EXECUTIVE SUMMARY
The purpose of this technical report is to assess the potential air quality and greenhouse gas
(GHG) emissions impacts associated with implementation of the proposed Bonita Glen Project
(Project). This assessment utilizes the significance thresholds in Appendix G of the California
Environmental Quality Act (CEQA) Guidelines (14 CCR 15000 et seq.).
Project Overview
The proposed Project is a 170-unit apartment development on a previously undeveloped 5.29-
acre site located in the City of Chula Vista (City), California. The site is located within the
Bonita Glen Specific Plan Area just west of the 805 Freeway and South of E Street and is shown
in Figure 1. The Project includes the development of 170 apartment units within six 3-story
garden-style buildings (two 21-plex buildings, two 18-plex buildings, and two 13-plex buildings)
and one 4-story podium-style building (66 units). Total building area for the project is
approximately 165,000 square feet. The proposed 170 units would be spread across 5 separate,
contiguous parcels, including Assessor Parcel Numbers 570-131-11-00, 570-140-40-00, 570-
140-54-00, 570-140-48-00, and 570-140-51-00, at a proposed density of 32 units/acre. The
Project includes covered (124 spaces) and uncovered (98 spaces) parking and recreation areas,
including a swimming pool, clubhouse, and dog park.
Air Quality
The air quality impact analysis evaluated the potential for adverse impacts to air quality due to
construction and operational emissions resulting from the Project. Impacts were evaluated for
their significance based on the City’s mass daily criteria air pollutant thresholds of significance.
Criteria air pollutants are defined as pollutants for which the federal and state governments have
established ambient air quality standards, or criteria, for outdoor concentrations to protect public
health. Criteria air pollutants include ozone (O3), nitrogen dioxide (NO2), carbon monoxide
(CO), sulfur dioxide (SO2), particulate matter with an aerodynamic diameter less than or equal to
10 microns (PM10), particulate matter with an aerodynamic diameter less than or equal to 2.5
microns (PM2.5), and lead. Pollutants that are evaluated include volatile organic compounds
(VOCs) (also referred to as reactive organic gases), oxides of nitrogen (NOx), CO, sulfur oxides
(SOx), PM10, and PM2.5. VOCs and NOx are important because they are precursors to O3.
Air Quality Plan Consistency
If a project proposes development that is greater than that anticipated in the local plan and San
Diego Association of Government’s (SANDAG’s) growth projections, the project might be in
conflict with the State Implementation Plan (SIP) and Regional Air Quality Strategy (RAQS)
Air Quality and Greenhouse Gas Emissions Analysis

and may contribute t o a potentially significant cumulative impact on air quality. The proposed
Project was deemed to be consistent with the current air quality plan, because the anticipated
growth associated with the Project does not exceed that projected by SANDAG. In addition, the
Project would not result in an increase in the frequency or severity of existing air quality violations
or cause or contribute to new violations. Based on these considerations, impacts related to the
Project’s potential to conflict with or obstruct implementation of the applicable air quality plan
would be less than significant.
Construction Criteria Air Pollutant Emissions
Construction of the Project would result in the temporary addition of pollutants to the local airshed
caused by on-site sources (i.e., off-road construction equipment, soil disturbance, and VOC off-
gassing) and off-site sources (i.e., on-road haul trucks, vendor trucks, and worker vehicle trips).
Maximum daily construction emissions would not exceed the City’s significance thresholds for VOC,
NOx, CO, SOx, PM10, or PM2.5 during construction in all construction years (2018–2020).
Operational Criteria Air Pollutant Emissions
Operational year 2021 was assumed consistent with the traffic report prepared for the project (Chen
Ryan 2017). Operation of the Project would generate operational criteria air pollutants from mobile
sources (vehicles), area sources (consumer product use, architectural coatings, and landscape
maintenance equipment), and energy (natural gas). Maximum operational emissions would not
exceed the City’s operational significance thresholds for VOC, NOx, CO, SOx, PM10, or PM2.5.
Exposure of Sensitive Receptors
Construction activities would not generate emissions in excess of the City’s site-specific mass daily
thresholds; therefore, site-specific construction impacts during construction of the Project would be less
than significant. In addition, diesel equipment would also be subject to the California Air Resources
Board (CARB) Airborne Toxic Control Measures (ATCMs) for in-use off-road diesel fleets, which
would minimize diesel particulate matter (DPM) emissions. No residual toxic air contaminants (TAC)
emissions and corresponding cancer risk are anticipated after construction, since no long-term sources
of TAC emissions are anticipated during operation of the Project. Therefore, the exposure of proximate
sensitive receptors to Project-generated TAC emissions and associated health risk impacts would be
less than significant. A Health Risk Assessment (HRA) was performed to determine the risk to Project
residents from the 805 freeway, which is approximately 276 feet from the eastern boundary of the site.
The results of the HRA show that the cancer risk on site from emissions from the 805 freeway would
exceed the SDAPCD threshold of 10 in 1 million and would result in a potentially significant impact.
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project

With mitigation, the cancer risk would be reduced to below the SDAPCD significance threshold and
therefore have a less than significant impact.
The Project would not negatively affect the level of service (LOS) of intersections on the Project site
and would not significantly contribute to a CO hotspot. In addition, no sensitive receptor land uses are
located near the only study area intersection that would operate at an unacceptable LOS. As such,
potential Project-generated impacts associated with CO hotspots would be less than significant.
Odors
Potential odors produced during construction would be attributable to concentrations of unburned
hydrocarbons from tailpipes of construction equipment, architectural coatings, and asphalt
pavement application, which would disperse rapidly from the Project site and generally occur at
magnitudes that would not affect substantial numbers of people. Impacts associated with odors
during construction would be less than significant. The Project is a residential development that
would not include land uses with sources that have the potential to generate substantial odors, and
impacts associated with odors during operation would be less than significant.
Cumulative Impacts
The potential for the Project to result in a cumulatively considerable impact is based on the
Project’s potential to exceed the project-specific daily thresholds. As discussed previously,
maximum construction and operational emissions would not exceed the City’s significance
thresholds for VOC, NOx, CO, SOx, PM10, or PM2.5. Therefore, the Project would not result in a
cumulatively considerable increase in criteria air pollutants.
Greenhouse Gas Emissions
Global climate change is primarily considered a cumulative impact but must also be evaluated on a
project-level under CEQA. A project participates in this potential impact through its incremental
contribution combined with the cumulative increase of all other sources of GHG emissions. GHGs are
gases that absorb infrared radiation in the atmosphere. Principal GHGs regulated under state and
federal law and regulations include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
GHG emissions are measured in metric tons of CO2 equivalent (MT CO2E), which account for
weighted global warming potential (GWP) factors for CH4 and N2O.
Project-Generated Construction and Operational Greenhouse Gas Emissions
Construction of the Proposed Project would result in GHG emissions primarily associated with
the use of off-road construction equipment, on-road hauling and vendor (material delivery)

trucks, and worker vehicles. Total proposed Project–generated GHG emissions during
construction were estimated to be 436.81 MT CO2E, or 14.56 MT CO2E per year when
amortized over 30 years.
The proposed Project would generate operational GHG emissions from area sources
(landscape maintenance), energy sources (electricity consumption), mobile sources (vehicle
trips), water supply and wastewater treatment, and solid waste. Estimated annual proposed
Project –generated operational GHG emissions at buildout in 2021 would be approximately
915.27 MT CO2 E per year.
Estimated annual proposed Project–generated operational emissions in 2021, plus amortized
Project construction emissions, would be approximately 929.83 MT CO2E per year. The service
population for the Project is anticipated to be 548 residents, resulting in an efficiency metric of
1.70 MT CO2E per person. This efficiency metric is lower than the significance threshold of 1.78
MT CO2E per person, which is based on the City’s Climate Action Plan (CAP) goal to reduce
GHG emissions 40% below 1990 levels by 2030. Therefore, the project would have a less-than-
significant impact.
Consistency with Applicable Greenhouse Gas Reduction Plans
The proposed Project was shown to be consistent with SANDAG’s Regional Plan, City’s CAP,
Senate Bill (SB) 32, and Executive Order (EO) S-3-05. The proposed Project does not conflict
with any plans adopted with the purpose of reducing GHG emissions; therefore, the proposed
Project’s impacts on GHG emissions would be less than significant.

1.2 Project Description
The proposed Project is a 170-unit apartment development on a previously undeveloped 5.29-
acre site located in the City of Chula Vista (City), California. The site is located within the
Bonita Glen Specific Plan Area just west of the 805 Freeway and South of E Street and is shown
in Figure 1. The Project includes the development of 170 apartment units within six 3-story
garden-style buildings (two 21-plex buildings, two 18-plex buildings, and two 13-plex buildings)
and one 4-story podium-style building (66 units). Total building area for the project is
approximately 165,000 square feet. The proposed 170 units would be spread across five separate,
contiguous parcels, including Assessor Parcel Numbers 570-131-11-00, 570-140-40-00, 570-
140-54-00, 570-140-48-00, and 570-140-51-00, at a proposed density of 32 units/acre. The
Project includes covered (124 spaces) and uncovered (98 spaces) parking and recreation areas ,
including a swimming pool, clubhouse, and dog park.
The Project is governed by the Bonita Glen Specific Plan, which proposes the development of
residential-retail-commercial projects on 8.74 acres of land. The plan is based upon special
standards and generalized site utilization plans, and is designed to promote innovative and
imaginative project planning. The text of the specific plan provides land use, bulk, height,

setback, urban design, parking, landscaping, and sign control standards and regulations. The
proposed Project utilizes State Density Bonus provisions that promote affordable housing
through the use of density bonuses, incentives or concessions, waivers or reductions to
development standards, and parking ratios in accordance with Section 65915 of the Government
Code and Chapter 19.90 of the Chula Vista Municipal Code. The proposed Project provid es 17
affordable dwelling units (10%) restricted for 55 years to lower-income households (80% of the
area median income) in a recorded restrictive covenant.

2 AIR QUALITY
2.1 Environmental Setting
The Project area is located within the San Diego Air Basin (SDAB) and is subject to the SDAPCD
guidelines and regulations. The SDAB is one of 15 air basins that geographically divide the State
of California. The weather of the San Diego region, as in most of Southern California, is
influenced by the Pacific Ocean and its semi-permanent high-pressure systems that result in dry,
warm summers and mild, occasionally wet winters. The average temperature ranges (in degrees
Fahrenheit (°F)) from the mid-40s to the high 90s. Most of the region’s precipitation falls from
November to April with infrequent (approximately 10%) precipitation during the summer. The
average seasonal precipitation along the coast is approximately 10 inches; the amount increases
with elevation as moist air is lifted over the mountains to the east.
The topography in the San Diego region varies greatly, from beaches on the west to mountains and
desert on the east. Along with local meteorology, the topography influences the dispersal and
movement of pollutants in the SDAB. The mountains to the east prohibit dispersal of pollutants in
that direction and help trap them in inversion layers as described in the next section.
The interaction of ocean, land, and the Pacific High Pressure Zone maintains clear skies for much
of the year and influences the direction of prevailing winds (westerly to northwesterly). Local
terrain is often the dominant factor inland, and winds in inland mountainous areas tend to blow
through the valleys during the day and down the hills and valleys at night.
2.1.1 Meteorological and Topographical Conditions
The SDAB lies in the southwest corner of California, comprises the entire San Diego region,
covers approximately covering 4,260 square miles, and is an area of high air pollution potential.
The SDAB experiences warm summers, mild winters, infrequent rainfalls, light winds, and
moderate humidity. This usually mild climatological pattern is interrupted infrequently by
periods of extremely hot weather, winter storms, or Santa Ana winds.
The SDAB experiences frequent temperature inversions. Subsidence inversions occur during the
warmer months as descending air associated with the Pacific High Pressure Zone meets cool
marine air. The boundary between the two layers of air creates a temperature inversion that traps
pollutants. Another type of inversion, a radiation inversion, develops on winter nights when air
near the ground cools by heat radiation and air aloft remains warm. The shallow inversion layer
formed between these two air masses also can trap pollutants. As the pollutants become more
concentrated in the atmosphere, photochemical reactions occur that produce ozone (O 3),
commonly known as smog.
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271

Light daytime winds, predominantly from the west, further aggravate the condition by driving air
pollutants inland, toward the mountains. During the fall and winter, air quality problems are
created due to carbon monoxide (CO) and oxides of nitrogen (NOx) emissions. CO
concentrations are generally higher in the morning and late evening. In the morning, CO levels
are elevated due to cold temperatures and the large number of motor vehicles traveling. Higher
CO levels during the late evenings are a result of stagnant atmospheric conditions trapping CO in
the area. Since CO is produced almost entirely from automobiles, the highest CO concentrations
in the basin are associated with heavy traffic. Nitrogen dioxide (NO2) levels are also generally
higher during fall and winter days when O3 concentrations are lower.
Under certain conditions, atmospheric oscillation results in the offshore transport of air from the
Los Angeles region to San Diego County (County). This often produces high O3 concentrations,
as measured at air pollutant monitoring stations within the County. The transport of air pollutants
from Los Angeles to San Diego has also occurred within the stable layer of the elevated
subsidence inversion, where high levels of O3 are transported.
The local climate in the southern part of the County is characterized as semi-arid with
consistently mild, warmer temperatures throughout the year. The average summertime high
temperature in the region is approximately 81°F, with highs approaching 80°F in August on
average, and record highs approaching 104°F in August. The average wintertime low
temperature is approximately 43.8°F, although record lows have approached 32°F in January.
Average precipitation in the local area is approximately 9.7 inches per year, with the bulk of
precipitation falling between December and March (WRCC 2017).
2.1.2 Pollutants and Effects
2.1.2.1 Criteria Air Pollutants
Criteria air pollutants are defined as pollutants for which the federal and state governments have
established ambient air quality standards, or criteria, for outdoor concentratio ns to protect public
health. The federal and state standards have been set, with an adequate margin of safety, at levels
above which concentrations could be harmful to human health and welfare. These standards are
designed to protect the most sensitive persons from illness or discomfort. Pollutants of concern
include O3, NO2, CO, sulfur dioxide (SO2), particulate matter with an aerodynamic diameter less
than or equal to 10 microns (PM10), particulate matter with an aerodynamic diameter less than or
equal to 2.5 microns (PM2.5), and lead. These pollutants, as well as toxic air contaminants

(TACs), are discussed in the following paragraphs.1 In California, sulfates, vinyl chloride,
hydrogen sulfide, and visibility-reducing particles are also regulated as criteria air pollutants.
Ozone. O3 is a strong-smelling, pale blue, reactive, toxic chemical gas consisting of three oxygen
atoms. It is a secondary pollutant formed in the atmosphere by a photochemical process involving
the sun’s energy and O3 precursors. These precursors are mainly NOx and volatile organic
compounds (VOCs). The maximum effects of precursor emissions on O3 concentrations usually
occur several hours after they are emitted and many miles from the source. Meteorology and
terrain play major roles in O3 formation, and ideal conditions occur during summer and early
autumn on days with low wind speeds or stagnant air, warm temperatures, and cloudless skies. O3
exists in the upper atmosphere O3 layer (stratospheric ozone) and at the Earth’s surface in the
troposphere (ozone).2 The O3 that the U.S. Environmental Protection Agency (EPA) and the
California Air Resources Board (CARB) regulate as a criteria air pollutant is produced close to the
ground level, where people live, exercise, and breathe. Ground-level O3 is a harmful air pollutant
that causes numerous adverse health effects and is, thus, considered “bad” O3. Stratospheric, or
“good,” O3 occurs naturally in the upper atmosphere, where it reduces the amount of ultraviolet
light (i.e., solar radiation) entering the Earth’s atmosphere. Without the protection of the beneficial
stratospheric O3 layer, plant and animal life would be seriously harmed.
O3 in the troposphere causes numerous adverse health effects; short-term exposures (lasting for a
few hours) to O3 at levels typically observed in Southern California can result in breathing pattern
changes, reduction of breathing capacity, increased susceptibility to infections, inflammation of the
lung tissue, and some immunological changes (EPA 2013). These health problems are particularly
acute in sensitive receptors such as the sick, the elderly, and young children.
Nitrogen Dioxide. NO2 is a brownish, highly reactive gas that is present in all urban
atmospheres. The major mechanism for the formation of NO 2 in the atmosphere is the
oxidation of the primary air pollutant nitric oxide, which is a colorless, odorless gas. NO x plays
a major role, together with VOCs, in the atmospheric reactions that produce O 3. NOx is formed
from fuel combustion under high temperature or pressure. In addition, NO x is an important
precursor to acid rain and may affect both terrestrial and aquatic ecosystems. The two ma jor
emissions sources are transportation and stationary fuel combustion sources , such as electric
utility and industrial boilers.
1 The descriptions of each of the criteria air pollutants and associated health effects are based on the EPA’s Criteria Air
Pollutants (2016a) and the CARB Glossary of Air Pollutant Terms (2016a).
2 The troposphere is the layer of the Earth’s atmosphere nearest to the surface of the Earth. The troposphere
extends outward about 5 miles at the poles and about 10 miles at the equator.

NO2 can irritate the lungs, cause bronchitis and pneumonia, and lower resistance to respiratory
infections (EPA 2016b).
Carbon Monoxide. CO is a colorless, odorless gas formed by the incomplete combustion of
hydrocarbon, or fossil fuels. CO is emitted almost exclusively from motor vehicles, power plants,
refineries, industrial boilers, ships, aircraft, and trains. In urban areas, such as the project location,
automobile exhaust accounts for the majority of CO emissions. CO is a nonreactive air pollutant
that dissipates relatively quickly; therefore, ambient CO concentrations generally follow the spatial
and temporal distributions of vehicular traffic. CO concentrations are influenced by local
meteorological conditions—primarily wind speed, topography, and atmospheric stability. CO from
motor vehicle exhaust can become locally concentrated when surface-based temperature inversions
are combined with calm atmospheric conditions, which is a typical situation at dusk in urban areas
from November to February. The highest levels of CO typically occur during the colder months of
the year, when inversion conditions are more frequent.
In terms of adverse health effects, CO competes with oxygen, often replacing it in the blood,
reducing the blood’s ability to transport oxygen to vital organs. The results of excess CO
exposure can include dizziness, fatigue, and impairment of central nervous system functions.
Sulfur Dioxide. SO2 is a colorless, pungent gas formed primarily from incomplete combustion
of sulfur-containing fossil fuels. The main sources of SO2 are coal and oil used in power plants
and industries; as such, the highest levels of SO2 are generally found near large industrial
complexes. In recent years, SO2 concentrations have been reduced by the increasingly stringent
controls placed on stationary source emissions of SO2 and limits on the sulfur content of fuels.
SO2 is an irritant gas that attacks the throat and lungs and can cause acute respiratory symptoms
and diminished ventilator function in children. When combined with particulate matter, SO2 can
injure lung tissue and reduce visibility and the level of sunlight. SO2 can also yellow plant leaves
and erode iron and steel.
Particulate Matter. Particulate matter pollution consists of very small liquid and solid particles
floating in the air, which can include smoke, soot, dust, salts, acids, and metals. Particulate
matter can form when gases emitted from industries and motor vehicles undergo chemical
reactions in the atmosphere. PM2.5 and PM10 represent fractions of particulate matter. Coarse
particulate matter (PM10) consists of particulate matter that is 10 microns or less in diameter and
is about 1/7 the thickness of a human hair. Major sources of PM10 include crushing or grinding
operations; dust stirred up by vehicles traveling on roads; wood-burning stoves and fireplaces;
dust from construction, landfills, and agriculture; wildfires and brush/waste burning; industrial
sources; windblown dust from open lands; and atmospheric chemical and photochemical

reactions. Fine particulate matter (PM2.5) consists of particulate matter that is 2.5 microns or less
in diameter and is roughly 1/28 the diameter of a human hair. PM2.5 results from fuel combustion
(e.g., from motor vehicles and power generation and industrial facilities), residential fireplaces,
and woodstoves. In addition, PM2.5 can be formed in the atmosphere from gases such as sulfur
oxides (SOx), NOx, and VOCs.
PM2.5 and PM10 pose a greater health risk than larger-size particles. When inhaled, these tiny particles
can penetrate the human respiratory system’s natural defenses and damage the respiratory tract.
PM2.5 and PM10 can increase the number and severity of asthma attacks, cause or aggravate
bronchitis and other lung diseases, and reduce the body’s ability to fight infections. Very small
particles of substances such as lead, sulfates, and nitrates can cause lung damage directly or be
absorbed into the blood stream, causing damage elsewhere in the body. Additionally, these
substances can transport adsorbed gases such as chlorides or ammonium into the lungs, also causing
injury. Whereas PM10 tends to collect in the upper portion of the respiratory system, PM2.5 is so tiny
that it can penetrate deeper into the lungs and damage lung tissue. Suspended particulates also
damage and discolor surfaces on which they settle and produce haze and reduce regional visibility.
People with influenza, people with chronic respiratory and cardiovascular diseases, and the elderly
may suffer worsening illness and premature death as a result of breathing particulate matter. People
with bronchitis can expect aggravated symptoms from breathing in particulate matter. Children may
experience a decline in lung function due to breathing in PM10 and PM2.5 (EPA 2009).
Lead. Lead in the atmosphere occurs as particulate matter. Sources of lead include leaded gasoline;
the manufacturing of batteries, paints, ink, ceramics, and ammunition; and secondary lead smelters.
Prior to 1978, mobile emissions were the primary source of atmospheric lead. Between 1978 and
1987, the phaseout of leaded gasoline reduced the overall inventory of airborne lead by nearly
95%. With the phaseout of leaded gasoline, secondary lead smelters, battery recycling, and
manufacturing facilities are becoming lead-emissions sources of greater concern.
Prolonged exposure to atmospheric lead poses a serious threat to human health. Health effects
associated with exposure to lead include gastrointestinal disturbances, anemia, kidney disease, and in
severe cases, neuromuscular and neurological dysfunction. Of particular concern are low-level lead
exposures during infancy and childhood. Such exposures are associated with decrements in
neurobehavioral performance, including intelligence quotient performance, psychomotor
performance, reaction time, and growth. Children are highly susceptible to the effects of lead.
Volatile Organic Compounds. Hydrocarbons are organic gases that are formed from hydrogen
and carbon and sometimes other elements. Hydrocarbons that contribute to formation of O3 are
referred to and regulated as VOCs (also referred to as reactive organic gases). Combustion
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
10 December 2018
engine exhaust, oil refineries, and fossil-fueled power plants are the sources of hydrocarbons.
Other sources of hydrocarbons include evaporation from petroleum fuels, solvents, dry cleaning
solutions, and paint.
The primary health effects of VOCs result from the formation of O3 and its related health effects.
High levels of VOCs in the atmosphere can interfere with oxygen intake by reducing the amount
of available oxygen through displacement. Carcinogenic forms of hydrocarbons, such as
benzene, are considered TACs. There are no separate health standards for VOCs as a group.
Sulfates. Sulfates are the fully oxidized form of sulfur, which typically occur in combination
with metals or hydrogen ions. Sulfates are produced from reactions of SO2 in the atmosphere.
Sulfates can result in respiratory impairment and reduced visibility.
Vinyl Chloride. Vinyl chloride is a colorless gas with a mild, sweet odor, which has been
detected near landfills, sewage plants, and hazardous waste sites, due to the microbial breakdown
of chlorinated solvents. Short-term exposure to high levels of vinyl chloride in the air can cause
nervous system effects such as dizziness, drowsiness, and headaches. Long-term exposure
through inhalation can cause liver damage, including liver cancer.
Hydrogen Sulfide. Hydrogen sulfide is a colorless and flammable gas that has a characteristic
odor of rotten eggs. Sources of hydrogen sulfide include geothermal power plants, petroleum
refineries, sewers, and sewage treatment plants. Exposure to hydrogen sulfide can result in
nuisance odors, as well as headaches and breathing difficulties at higher concentrations.
Visibility-Reducing Particles. Visibility-reducing particles are any particles in the air that
obstruct the range of visibility. Effects of reduced visibility can include obscuring the viewshed
of natural scenery, reducing airport safety, and discouraging tourism. Sources of visibility-
reducing particles are the same as for PM2.5, described above.
2.1.2.2 Non-Criteria Air Pollutants
Toxic Air Contaminants. A substance is considered toxic if it has the potential to cause adverse
health effects in humans, including increasing the risk of cancer upon exposure, or acute and/or
chronic noncancer health effects. A toxic substance released into the air is considered a TAC.
TACs are identified by federal and state agencies based on a review of available scientific
evidence. In the State of California, TACs are identified through a two-step process that was
established in 1983 under the Toxic Air Contaminant Identification and Control Act. This two-
step process of risk identification and risk management and reduction was designed to protect
residents from the health effects of toxic substances in the air. In addition, the California Air
Toxics “Hot Spots” Information and Assessment Act, Assembly Bill (AB) 2588, was enacted by
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
11 December 2018
the legislature in 1987 to address public concern over the release of TACs into the atmosphere.
The law requires facilities emitting toxic substances to provide local air pollution control districts
with information that will allow an assessment of the air toxics problem, identification of air toxics
emissions sources, location of resulting hotspots, notification of the public exposed to significant
risk, and development of effective strategies to reduce potential risks to the public over 5 years.
Examples include certain aromatic and chlorinated hydrocarbons, certain metals, and asbestos.
TACs are generated by a number of sources, including stationary sources, such as dry cleaners,
gas stations, combustion sources, and laboratories; mobile sources, such as automobiles; and area
sources, such as landfills. Adverse health effects associated with exposure to TACs may include
carcinogenic (i.e., cancer-causing) and noncarcinogenic effects. Noncarcinogenic effects
typically affect one or more target organ systems and may be experienced on either short-term
(acute) or long-term (chronic) exposure to a given TAC.
Diesel Particulate Matter. Diesel particulate matter (DPM) is part of a complex mixture that
makes up diesel exhaust. Diesel exhaust is composed of two phases, gas and particle, both of
which contribute to health risks. More than 90% of DPM is less than 1 micrometer in diameter
(about 1/70th the diameter of a human hair) and, thus, is a subset of PM2.5 (CARB 2016a). DPM
is typically composed of carbon particles (“soot,” also called black carbon) and numerous
organic compounds, including over 40 known cancer-causing organic substances. Examples of
these chemicals include polycyclic aromatic hydrocarbons, benzene, formaldehyde,
acetaldehyde, acrolein, and 1,3-butadiene (CARB 2016a). The CARB classified “particulate
emissions from diesel-fueled engines” (i.e., DPM; 17 CCR 93000) as a TAC in August 1998.
DPM is emitted from a broad range of diesel engines: on-road diesel engines of trucks, buses,
and cars and off-road diesel engines, including locomotives, marine vessels, and heavy-duty
construction equipment, among others. Approximately 70% of all airborne cancer risk in
California is associated with DPM (CARB 2000). To reduce the cancer risk associated with
DPM, CARB adopted a diesel risk reduction plan in 2000 (CARB 2000). Because it is part of
PM2.5, DPM also contributes to the same non-cancer health effects as PM2.5 exposure. These
effects include premature death; hospitalizations and emergency department visits for
exacerbated chronic heart and lung disease, including asthma; increased respiratory symptoms;
and decreased lung function in children. Several studies suggest that exposure to DPM may also
facilitate development of new allergies (CARB 2016b). Those most vulnerable to non-cancer
health effects are children whose lungs are still developing and the elderly who often have
chronic health problems.
Odorous Compounds. Odors are generally regarded as an annoyance rather than a health hazard.
Manifestations of a person’s reaction to odors can range from psychological (e.g., irritation,
anger, or anxiety) to physiological (e.g., circulatory and respiratory effects, nausea, vomiting,
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
12 December 2018
and headache). The ability to detect odors varies considerably among the population and, overall,
is quite subjective. People may have different reactions to the same odor. An odor that is
offensive to one person may be perfectly acceptable to another (e.g., coffee roaster). An
unfamiliar odor is more easily detected and is more likely to cause complaints than a familiar
one. Known as odor fatigue, a person can become desensitized to almost any odor, and
recognition may only occur with an alteration in the intensity. The occurrence and severity of
odor impacts depend on the nature, frequency, and intensity of the source; wind speed and
direction; and the sensitivity of receptors.
2.1.3 Sensitive Receptors
Some land uses are considered more sensitive to changes in air quality than others, depending on
the population groups and the activities involved. People most likely to be affected by air
pollution include children, the elderly, athletes, and people with cardiovascular and chronic
respiratory diseases. Facilities and structures where these air pollution-sensitive people live or
spend considerable amounts of time are known as sensitive receptors. Land uses where air
pollution–sensitive individuals are most likely to spend time include schools and schoolyards,
parks and playgrounds, daycare centers, nursing homes, hospitals, and residential communities
(sensitive sites or sensitive land uses) (CARB 2005). The SDAPCD identifies sensitive receptors
as those who are especially susceptible to adverse health effects from exposure to toxic air
contaminants, such as children, the elderly, and the ill. Sensitive receptors include schools (grades
Kindergarten through 12), day care centers, nursing homes, retirement homes, health clinics, and
hospitals within 2 kilometers of the facility (SDAPCD 2015a). The closest sensitive receptors to
the Proposed Project are residences adjacent to the western and eastern property boundaries.
2.2 Regulatory Setting
2.2.1 Federal Regulations
2.2.1.1 Criteria Air Pollutants
The federal Clean Air Act (CAA), passed in 1970 and last amended in 1990, forms the basis
for the national air pollution control effort. The EPA is responsible for implementing most
aspects of the CAA, including the setting of the National Ambient Air Qualit y Standards
(NAAQS) for major air pollutants, hazardous air pollutant standards, approval of state
attainment plans, motor vehicle emission standards, stationary source emission standards and
permits, acid rain control measures, stratospheric O 3 protection, and enforcement provisions.
Under the CAA, NAAQS are established for the following criteria pollutants: O3, CO, NO2, SO2,
PM10, PM2.5, and lead. The NAAQS describe acceptable air quality conditions designed to
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
13 December 2018
protect the health and welfare o f the citizens of the nation. The CAA requires the EPA to
reassess the NAAQS at least every 5 years to determine whether adopted standards are
adequate to protect public health based on current scientific evidence. States with areas that
exceed the NAAQS must prepare a State Implementation Plan (SIP) that demonstrates how
those areas will attain the standards within mandated time frames.
2.2.1.2 Hazardous Air Pollutants
The 1977, federal CAA amendments required the EPA to identify National Emission Standard s
for Hazardous Air Pollutants to protect public health and welfare. Hazardous air pollutants
include certain volatile organic chemicals, pesticides, herbicides, and radionuclides that present
a tangible hazard, based on scientific studies of exposure to h umans and other mammals.
Under the 1990 CAA amendments, which expanded the control program for Hazardous Air
Pollutants, 189 substances and chemical families were identified as Hazardous Air Pollutants.
2.2.2 State Regulations
2.2.2.1 Criteria Air Pollutants
The federal CAA delegates the regulation of air pollution control and the enforcement of the
NAAQS to the states. In California, the task of air quality management and regulation has been
legislatively granted to the CARB, with subsidiary responsibilities assigned to air quality
management districts and air pollution control districts at the regional and county levels. CARB,
which became part of the California Environmental Protection Agency in 1991, is responsible for
ensuring implementation of the California Clean Air Act of 1988, responding to the CAA and
regulating emissions from motor vehicles and consumer products.
CARB has established California Ambient Air Quality Standards (CAAQS), which are generally
more restrictive than the NAAQS. The CAAQS describe adverse conditions; that is, pollution
levels must be below these standards before a basin can attain the standard. Air quality is
considered “in attainment” if pollutant levels are continuously below the CAAQS and violate the
standards no more than once each year. The CAAQS for O3, CO, SO2 (1-hour and 24-hour),
NO2, PM10, PM2.5, and visibility-reducing particles are values that are not to be exceeded. All
others are not to be equaled or exceeded.
The NAAQS and CAAQS are presented in Table 1.

a California standards for O3, CO, SO2 (1-hour and 24-hour), NO2, suspended particulate matter (PM10, PM2.5), and visibility-reducing
particles are values that are not to be exceeded. All others are not to be equaled or exceeded. CAAQS are listed in the Table of
Standards in Section 70200 of Title 17 of the California Code of Regulations.

b National standards (other than O3, NO2, SO2, particulate matter, and those based on annual averages or annual arithmetic mean) are not
to be exceeded more than once per year. The O3 standard is attained when the fourth highest 8-hour concentration measured at each site
in a year, averaged over 3 years, is equal to or less than the standard. For PM10, the 24-hour standard is attained when the expected
number of days per calendar year with a 24-hour average concentration above 150 µg/m3 is equal to or less than 1. For PM2.5, the 24-
hour standard is attained when 98% of the daily concentrations, averaged over 3 years, are equal to or less than the standard.
c Concentration expressed first in units in which it was promulgated. Equivalent units given in parentheses are based on a reference
temperature of 25°C and a reference pressure of 760 torr. Most measurements of air quality are to be corrected to a reference temperature of
25°C and a reference pressure of 760 torr; ppm in this table refers to ppm by volume, or micromoles of pollutant per mole of gas.
d National Primary Standards: The levels of air quality necessary, with an adequate margin of safety, to protect the public health.
e National Secondary Standards: The levels of air quality necessary to protect the public welfare from any known or anticipated adverse
effects of a pollutant.
f On October 1, 2015, the national 8-hour O3 primary and secondary standards were lowered from 0.075 to 0.070 ppm.
g To attain the national 1-hour standard, the 3-year average of the annual 98th percentile of the 1-hour daily maximum concentrations at
each site must not exceed 100 parts per billion (ppb). Note that the national 1-hour standard is in units of ppb. California standards are in
units of ppm. To directly compare the national 1-hour standard to the California standards, the units can be converted from ppb to ppm. In
this case, the national standard of 100 ppb is identical to 0.100 ppm.
h On June 2, 2010, a new 1-hour SO2 standard was established, and the existing 24-hour and annual primary standards were revoked. To
attain the national 1-hour standard, the 3-year average of the annual 99th percentile of the 1-hour daily maximum concentrations at each
site must not exceed 75 ppb. The 1971 SO2 national standards (24-hour and annual) remain in effect until 1 year after an area is
designated for the 2010 standard, except that in areas designated nonattainment of the 1971 standards, the 1971 standards remain in
effect until implementation plans to attain or maintain the 2010 standards are approved.
i On December 14, 2012, the national annual PM2.5 primary standard was lowered from 15 g/m3 to 12.0 g/m3. The existing national 24-
hour PM2.5 standards (primary and secondary) were retained at 35 g/m3, as was the annual secondary standard of 15 μg/m3. The
existing 24-hour PM10 standards (primary and secondary) of 150 g/m3 were also retained. The form of the annual primary and
secondary standards is the annual mean averaged over 3 years.
j California Air Resources Board has identified lead and vinyl chloride as toxic air contaminants with no threshold level of exposure for
adverse health effects determined. These actions allow for the implementation of control measures at levels below the ambient
concentrations specified for these pollutants.
k The national standard for lead was revised on October 15, 2008, to a rolling 3-month average. The 1978 lead standard (1.5 μg/m3 as a
quarterly average) remains in effect until 1 year after an area is designated for the 2008 standard, except that in areas designated
nonattainment for the 1978 standard, the 1978 standard remains in effect until implementation plans to attain or maintain the 2008
standard are approved.
2.2.2.2 Toxic Air Contaminants
A TAC is defined by California law as an air pollutant that may cause or contribute to an
increase in mortality or an increase in serious illness, or which may pose a present or potential
hazard to human health. Federal laws use the Hazardous Air Pollutant s to refer to the same types
of compounds that are referred to as TACs under state law. California regulates TACs primarily
through the Tanner Air Toxics Act (AB 1807) and the Air Toxics Hot Spots Information and
Assessment Act of 1987 (AB 2588).
AB 1807 sets forth a formal procedure for CARB to designate substances as TACs. This
includes research, public participation, and scientific peer review before CARB can
designate a substance as a TAC. Pursuant to AB 2588, existing facilities that emit air
pollutan ts above specified level were required to (1) prepare a TAC emission inventory plan
and report, (2) prepare a risk assessment if TAC emissions were significant, (3) notify the
public of significant risk levels, and (4) if health impacts were above specifie d levels,
prepare and implement risk reduction measures.
Air Quality and Greenhouse Gas Emissions Analysis

16 December 2018
The following regulatory measures pertain to the reduction of DPM and criteria pollutant
emissions from off-road equipment and diesel-fueled vehicles:
Idling of Commercial Heavy Duty Trucks (13 CCR 2485)
In July 2004, CARB adopted an Airborne Toxic Control Measure (ATCM) to control emissions
from idling trucks. The ATCM prohibits idling for more than 5 minutes for all commercial trucks
with a gross vehicle weight rating over 10,000 pounds. The ATCM contains an exception that
allows trucks to idle while queuing or involved in operational activities.
In-Use Off-Road Diesel-Fueled Fleets (13 CCR 2449 et seq.)
In July 2007, CARB adopted an ATCM for in-use off-road diesel vehicles. This regulation
requires that specific fleet average requirements are met for NOx emissions and for particulate
matter emissions. Where average requirements cannot be met, Best Available Control
Technology requirements apply. The regulation also includes several recordkeeping and
reporting requirements.
In response to AB 8 2X, the regulations were revised in July 2009 (effective December 3, 2009)
to allow a partial postponement of the compliance schedule in 2011 and 2012 for existing fleets.
On December 17, 2010, CARB adopted additional revisions to further delay the deadlines
reflecting reductions in diesel emissions due to the poor economy and overestimates of diesel
emissions in California. The revisions delayed the first compliance date until no earlier than
January 1, 2014, for large fleets, with final compliance by January 1, 2023. The compliance dates
for medium fleets were delayed until an initial date of January 1, 2017, and final compliance date
of January 1, 2023. The compliance dates for small fleets were delayed until an initial date of
January 1, 2019, and final compliance date of January 1, 2028. Correspondingly, the fleet
average targets were made more stringent in future compliance years. The revisions also
accelerated the phaseout of equipment with older equipment added to existing large and medium
fleets over time, requiring the addition of Tier 2 or higher engines starting on March 1, 2011,
with some exceptions: Tier 2 or higher engines on January 1, 2013, without exception; and Tier 3
or higher engines on January 1, 2018 (January 1, 2023, for small fleets).
On October 28, 2011 (effective December 14, 2011), the Executive Officer approved amendments
to the regulation. The amendments included revisions to the applicability section and additions and
revisions to the definition. The initial date for requiring the addition of Tier 2 or higher engines for
large and medium fleets, with some exceptions, was revised to January 1, 2012. New provisions
also allow for the removal of emission control devices for safety or visibility purposes. The
regulation also was amended to combine the particulate matter and NOx fleet average targets under
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
17 December 2018
one, instead of two, sections. The amended fleet average targets are based on the fleet’s NOx fleet
average, and the previous section regarding particulate matter performance requirements was
deleted completely. The Best Available Control Technology requirements, if a fleet cannot comply
with the fleet average requirements, were restructured and clarified. Other amendments to the
regulations included minor administrative changes to the regulatory text.
In-Use On-Road Diesel-Fueled Vehicles (13 CCR 2025)
On December 12, 2008, CARB adopted an ATCM to reduce NOx and particulate matter
emissions from most in-use on-road diesel trucks and buses with a gross vehicle weight rating
greater than 14,000 pounds. The original ATCM regulation required fleets of on -road trucks to
limit their NOx and particulate matter emissions through a combination of exhaust retrofit
equipment and new vehicles. The regulation limited particulate matter emissions for most fleets
by 2011, and limited NOx emissions for most fleets by 2013. The regulation did not require any
vehicle to be replaced before 2012 and never required all vehicles in a fleet be replaced.
In December 2009, the CARB Governing Board directed staff to evaluate amendments that
would provide additional flexibility for fleets adversely affected by the poor California economy.
On December 17, 2010, CARB revised this ATCM to delay its implementation along with
limited relaxation of its requirements. Starting on January 1, 2015, lighter trucks with a gross
vehicle weight rating of 14,001 to 26,000 pounds with 20-year-old or older engines need to be
replaced with newer trucks (2010 model year emissions equivalent as defined in the regulation).
Trucks with a gross vehicle weight rating greater than 26,000 pounds with 1995 model year or
older engines needed to be replaced as of January 1, 2015. Trucks with 1996–2006 model year
engines must install a Level 3 (85% control) diesel particulate filter starting on January 1, 2012,
to January 1, 2014, depending on the model year, and then must be replaced after 8 years. Trucks
with 2007–2009 model year engines have no requirements until 2023, at which time they must
be replaced with 2010 model year emissions equivalent engines, as defined in the regulation.
Trucks with 2010 model year engines would meet the final compliance requirements. The
ATCM provides a phase-in option under which a fleet operator would equip a percentage of
trucks in the fleet with diesel particulate filters, starting at 30% as of January 1, 2012, with 100%
by January 1, 2016. Under each option, delayed compliance is granted to fleet operators who
have or will comply with requirements before the required deadlines.
On September 19, 2011 (effective December 14, 2011), the Executive Officer approved
amendments to the regulations, including revisions to the compliance schedule for vehicles with
a gross vehicle weight rating of 26,000 pounds or less to clarify that all vehicles must be
equipped with 2010 model year emissions equivalent engines by 2023. The amendments
included revised and additional credits for fleets that have downsized; implement early

Technical Report for the Bonita Glen Project
10271
18 December 2018
particulate matter retrofits; incorporate hybrid vehicles, alternative-fueled vehicles, and vehicles
with heavy-duty pilot ignition engines; and implement early addition of newer vehicles. The
amendments included provisions for additional flexibility, such as for low-usage construction
trucks, and revisions to previous exemptions, delays, and extensions. Other amendments to the
regulations included minor administrative changes to the regulatory text, including
recordkeeping and reporting requirements related to other revisions.
California Health and Safety Code Section 41700
Section 41700 of the California Health and Safety Code states that a person shall not discharge
from any source whatsoever quantities of air contaminants or other material that cause injury,
detriment, nuisance, or annoyance to any considerable number of persons or to the public, or that
endanger the comfort, repose, health, or safety of any of those persons or the public, or that
cause, or have a natural tendency to cause, injury or damage to business or property. This section
also applies to sources of objectionable odors.
2.2.3 Local Regulations
2.2.3.1 San Diego Air Pollution Control District
While CARB is responsible for the regulation of mobile emission sources within the state, local
air quality management districts and air pollution control districts are responsible for enforcing
standards and regulating stationary sources. The Project area is located within the SDAB and is
subject to the guidelines and regulations of the SDAPCD.
In the County, O3 and particulate matter are the pollutants of main concern, since exceedances of
state ambient air quality standards for those pollutants are experienced here in most years. For
this reason, the SDAB has been designated as a nonattainment area for the state PM10, PM2.5, and
O3 standards. The SDAB is also a federal O3 attainment (maintenance) area for 1997 8-hour O3
standard, an O3 nonattainment area for the 2008 8-hour O3 standard, and a CO maintenance area
(western and central part of the SDAB only, including the Project area).
Federal Attainment Plans
In December 2016, the SDAPCD adopted an update to the Eight-Hour Ozone Attainment Plan
for San Diego County (2008 O3 NAAQS). The 2016 Eight-Hour Ozone Attainment Plan for San
Diego County indicates that local controls and state programs would allow the region to reach
attainment of the federal 8-hour O3 standard (1997 O3 NAAQS) by 2018 (SDAPCD 2016a). In
this plan, SDAPCD relies on the Regional Air Quality Strategy (RAQS) to demonstrate how the
region will comply with the federal O3 standard. The RAQS details how the region will manage

and reduce O3 precursors (NOx and VOCs) by identifying measures and regulations intended to
reduce these pollutants. The control measures identified in the RAQS generally focus on
stationary sources; however, the emissions inventories and projections in the RAQS address all
potential sources, including those under the authority of CARB and the EPA. Incentive programs
for reduction of emissions from heavy-duty diesel vehicles, off-road equipment, and school
buses are also established in the RAQS.
Currently, the County is designated as moderate nonattainment for the 2008 NAAQS and
maintenance for the 1997 NAAQS. As documented in the 2016 8 -Hour Ozone Attainment Plan
for San Diego County, the County has a likely chance of obtaining attainment due to the
transition to low-emission cars, stricter new source review rules, and continuing the requirement
of general conformity for military growth and the San Diego International Airport. The County
will also continue emission control measures, including ongoing implementation of existing
regulations in ozone precursor reduction to stationary and area-wide sources, subsequent
inspections of facilities and sources, and the adoption of laws requiring Best Available Retrofit
Control Technology for control of emissions (SDAPCD 2016a).
State Attainment Plans
The SDAPCD and the SANDAG are r esponsible for developing and implementing the clean
air plan for attainment and maintenance of the ambient air quality standards in the SDAB. The
RAQS for the SDAB was initially adopted in 1991 and is updated on a triennial basis, most
recently in 2016 (S DAPCD 2016b). The RAQS outlines SDAPCD’s plans and control
measures designed to attain the state air quality standards for O 3. The RAQS relies on
information from CARB and SANDAG, including mobile and area source emissions, as well
as information regarding projected growth in the County and the cities in the County, to
forecast future emissions and then determine from that the strategies necessary for the
reduction of emissions through regulatory controls. CARB mobile source emission projections
and SANDAG growth projections are based on population, vehicle trends, and land use plans
developed by the County and the cities in the County as part of the development of their
general plans (SANDAG 2017a, 2017b).
In December 2016, the SDAPCD adopted the revised RAQS for the County. Since 2007, the San
Diego region reduced daily VOC emissions and NOx emissions by 3.9% and 7.0%, respectively;
the SDAPCD expects to continue reductions through 2035 (SDAPCD 2016b). These reductions
were achieved through implementation of six VOC control measures and three NOx control
measures adopted in the SDAPCD’s 2009 RAQS (SDAPCD 2009a); in addition, the SDAPCD is
considering additional measures, including three VOC measures and four control measures to
reduce 0.3 daily tons of VOC and 1.2 daily tons of NOx, provided they are found to be feasible
Air Quality and Greenhouse Gas Emissions Analysis

region-wide. In addition, SDAPCD has implemented nine incentive-based programs, has worked
with SANDAG to implement regional transportation control measures, and has reaffirmed the
state emission offset repeal.
In regards to particulate matter emissions reduction efforts, in December 2005, the SDAPCD
prepared a report titled “Measures to Reduce Particulate Matter in San Diego County” to address
implementation of Senate Bill (SB) 656 in San Diego County (SB 656 required additional
controls to reduce ambient concentrations of PM 10 and PM2.5) (SDAPCD 2005). In the report,
SDAPCD evaluated implementation of source-control measures that would reduce particulate
matter emissions associated with residential wood combustion; various construction activities
including earthmoving, demolition, and grading; bulk material storage and handling; carryout
and trackout removal and cleanup methods; inactive disturbed land; disturbed open areas;
unpaved parking lots/staging areas; unpaved roads; and windblown dust (SDAPCD 2005).
SDAPCD Rules and Regulations
As stated above, the SDAPCD is responsible for planning, implementing, and enforcing federal
and state ambient standards in the SDAB. The following rules and regulations apply to all
sources in the jurisdiction of SDAPCD and would apply to the Project:
SDAPCD Regulation II: Permits; Rule 20.2: New Source Review Non-Major Stationary
Sources. Requires new or modified stationary source units (that are not major stationary sources)
with the potential to emit 10 pounds per day or more of VOC, NOx, SOx, or PM10 to be equipped
with Best Available Control Technology. For those units with a potential to emit above Air Quality
Impact Assessments Trigger Levels, the units must demonstrate that such emissions would not
violate or interfere with the attainment of any national air quality standard (SDAPCD 2016b).
The Project does not propose specific stationary sources. If stationary sources were to be
included as part of the Project, or at a later date, those sources would be subject to Rule 20.2 and
would require appropriate operating permits from the SDAPCD. Because the SDAPCD has not
adopted specific criteria air pollutant thresholds for CEQA analyses, the thresholds identified in
Rule 20.2 are utilized in this analysis as screening-level thresholds to evaluate project-level
impacts, as discussed in Section 2.4.1.
SDAPCD Regulation IV: Prohibitions; Rule 50: Visible Emissions. Prohibits discharge into the
atmosphere from any single source of emissions whatsoever any air contaminant for a period or
periods aggregating more than 3 minutes in any period of 60 consecutive minutes, which is darker in
shade than that designated as Number 1 on the Ringelmann Chart, as published by the United States
Air Quality and Greenhouse Gas Emissions Analysis

21 December 2018
Bureau of Mines, or of such opacity as to obscure an observer's view to a degree greater than does
smoke of a shade designated as Number 1 on the Ringelmann Chart (SDAPCD 1997).
Construction of the Project may result in visible emissions, primarily during earth-disturbing
activities, which would be subject to SDAPCD Rule 50. Although visible emissions are less
likely to occur during operation of the Project, compliance with SDAPCD Rule 50 would be
required during both construction and operational phases.
SDAPCD Regulation IV: Prohibitions; Rule 51: Nuisance. Prohibits the discharge, from any
source, of such quantities of air contaminants or other materials that cause or have a tendency to
cause injury, detriment, nuisance, annoyance to people and/or the public, or damage to any
business or property (SDAPCD 1969).
Any criteria air pollutant emissions, TAC emissions, or odors that would be generated during
construction or operation of the Project would be subject to SDAPCD Rule 51. Violations can be
reported to the SDAPCD in the form of an air quality compliant by telephone, email, and online
form. Complaints are investigated by the SDAPCD as soon as possible.
SDAPCD Regulation IV: Prohibitions; Rule 55: Fugitive Dust. Regulates fugitive dust emissions
from any commercial construction or demolition activity capable of generating fugitive dust
emissions, including active operations, open storage piles, and inactive disturbed areas, as well as
track-out and carry-out onto paved roads beyond a project area (SDAPCD 2009b).
Construction of the Project, primarily during earth-disturbing activities, may result in fugitive
dust emissions that would be subject to SDAPCD Rule 55. Fugitive dust emissions are not
anticipated during operation of the Project.
SDAPCD Regulation IV: Prohibitions; Rule 67.0.1: Architectural Coatings. Requires
manufacturers, distributors, and end users of architectural and industrial maintenance coatings to
reduce VOC emissions from the use of these coatings, primarily by placing limits on the VOC
content of various coating categories (SDAPCD 2015a). Construction and operation of the Project
would include application of architectural coatings (e.g., paint and other finishes), which are subject
to SDAPCD Rule 67.0.1. Architectural coatings used in the reapplication of coatings during
operation of the Project would be subject to the VOC content limits identified in SDAPCD Rule
67.0.1, which applies to coatings manufactured, sold, or distributed within San Diego County.
SDAPCD Regulation XII: Toxic Air Contaminants; Rule 1200: Toxic Air Contaminants -
New Source Review. Requires new or modified stationary source units with the potential to
emit TACs above rule threshold levels to either demonstrate that the y will not increase the
maximum incremental cancer risk above 1 in 1 million at every receptor location, demonstrate
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271

that toxics best available control technology will be employed if maximum incremental cancer
risk is equal to or less than 10 in 1 million, or demonstrate compliance with the SDAPCD’s
protocol for those sources with an increase in maximum incremental cancer risk at any receptor
location of greater than 10 in 1 million but less than 100 in 1 million (SDAPCD 2017a).
The Project does not propose specific stationary sources that would generate TACs that are not
commonly associated with residential development projects. If stationary sources with the potential
to emit TACs were to be included as part of the Project, or at a later date, those sources would be
subject to SDAPCD Rule 1200, and would be subject to New Source Review requirements.
SDAPCD Regulation XII: Toxic Air Contaminants; Rule 1210: Toxic Air Contaminant
Public Health Risks –Public Notification and Risk Reduction. Requires each stationary
source required to prepare a public risk assessment to provide written public notice of risks at or
above the following levels: maximum incremental cancer risks equal to or greater than 10 in 1
million, cancer burden equal to or greater than 1.0, total acute noncancer health hazard index
equal to or greater than 1.0, or total chronic noncancer health hazard index equal to or greater
than 1.0 (SDAPCD 2017b).
The Project does not propose specific stationary sources that would generate TACs. If stationary
sources with the potential to emit TACs were to be included as part of the Project, or at a later date,
those sources would be subject to SDAPCD Rule 1210 and would be subject to Public Notification
and Risk Reduction requirements. The thresholds identified in Rule 1210 are utilized in this
analysis as thresholds for the health risk assessment (HRA) as described in Section 2.4.1, which are
consistent with the SDAPCD HRA Guidelines (SDAPCD 2015b).
2.2.3.2 San Diego Association of Governments
SANDAG is the regional planning agency for the County and serves as a forum for regional
issues relating to transportation, the economy, community development, and the environment.
SANDAG serves as the federally designated metropolitan planning organization for the County.
With respect to air quality planning and other regional issues, SANDAG has prepared San Diego
Forward: The Regional Plan (Regional Plan) for the San Diego region (SANDAG 2015). The
Regional Plan combines the big-picture vision for how the region will grow over the next 35
years with an implementation program to help make that vision a reality. The Regional Plan,
including its Sustainable Communities Strategy (SCS), is built on an integrated set of public
policies, strategies, and investments to maintain, manage, and improve the transportation system
so that it meets the diverse needs of the San Diego region through 2050.
In regards to air quality, the Regional Plan sets the policy context in which SANDAG
participates in and responds to the air district’s air quality plans and builds off the air district’s
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
23 December 2018
air quality plan processes that are designed to meet health-based criteria pollutant standards in
several ways (SANDAG 2015). First, it complements air quality plans by providing guidance
and incentives for public agencies to consider best practices that support the technology-based
control measures in air quality plans. Second, the Regional Plan emphasizes the need for better
coordination of land use and transportation planning, which heavily influences the emissions
inventory from the transportation sectors of the economy. This also minimizes land use conflicts,
such as residential development near freeways, industrial areas, or other sources of air pollution.
On September 23, 2016, SANDAG’s Board of Directors adopted the final 2016 Regional
Transportation Improvement Program. The 2016 Regional Transportation Improvement Program is a
multi-billion dollar, multi-year program of proposed projects for major transportation projects in the
San Diego region. Transportation projects funded with federal, state, and TransNet (the San Diego
transportation sales tax program) must be included in an approved Regional Transportation
Improvement Program. The programming of locally funded projects also may be programmed at the
discretion of the agency. The 2016 Regional Transportation Improvement Program covers five fiscal
years and incrementally implements the Regional Plan (SANDAG 2016).
2.2.3.3 Chula Vista General Plan
In the Environmental Element of the Chula Vista General Plan, the City outlines in Chapter
3.1.6, Promoting Clean Air, the background of air quality in the region and the following
objectives and policies related to air quality (City of Chula Vista 2005):
E6: Improve local air quality and red uce greenhouse gas emissions by minimizing the
release of air pollutants and toxic air contaminants and limiting the exposure of
people to such pollutants.
E6A: Explore opportunities for improving indoor air quality.
E6B: Prioritize greening efforts to keep air, water, and land clean.
The following policies related to air quality are found in Section 3.1.6 of the Environmental
Element in the Chula Vista General Plan:
E6.1: Encourage compact development featuring a mix of uses that locate residential areas
within reasonable walking distance to jobs, services, and transit.
E6.2: Promote and facilitate transit system improvements in order to increase transit use and
reduce dependency on the automobile.
Air Quality and Greenhouse Gas Emissions Analysis

24 December 2018
E6.3: Facilitate the use of alternative fuel and low- and zero-emission vehicles and equipment
in the community.
E6.4: Do not site new or re-powered fossil-fueled baseload or peaking-type Electric Generating
Facilities and other major toxic emitters within 1,000 feet of sensitive receptors, or site
sensitive receptors within 1,000 feet of such facilities.
E6.5: Ensure Electrical Generating Facilities incorporate cleaner fuel sources and least
polluting technologies in order to help transition the City to a less fossil fuel dependent
future, while meeting Chula Vista’s energy demand.
E6.6: Explore incentives to promote voluntary air pollutant reductions, including incentives for
developers who go above and beyond applicable requirements and for facilities and
operations that are not otherwise regulated.
E6.7: Encourage innovative energy conservation practices and air quality improvements in new
development and redevelopment projects consistent with the City's Air Quality
Improvement Plan Guidelines or its equivalent, pursuant to the City's Growth
Management Program.
E6.9: Discourage the use of landscaping equipment powered by two -stroke gasoline engines
within the City and promote less-polluting alternatives to their use.
E6.10: The siting of new sensitive receivers within 500 feet of highways resulting from
development or redevelopment projects shall require the preparation of a health risk
assessment as part of the CEQA review of the project. Attendant health risks identified in
the Health Risk Assessment (HRA) shall be feasibly mitigated to the maximum extent
practicable, in accordance with CEQA, in order to help ensure that applicable federal and
state standards are not exceeded.
E6.11: Develop strategies to minimize CO hot spots that address all modes of transportation.
E6.12: Promote clean fuel sources that help reduce the exposure of sensitive uses to pollutants.
E6.13: Encourage programs and infrastructure to increase the availability and usage of energy-
efficient vehicles, such as hybrid electric vehicles, electric vehicles, or those that run on
alternative fuels.
E6.14: Transition the City fleet to 100% “clean” vehicles by integrating hybrid and alternative
fuel vehicles as current municipal fleet vehicles are replaced.

E6.15: Site industries and other stationary emitters in a way that minimizes the potent ial impacts
of poor air quality on homes, schools, hospitals, and other land uses where people
congregate, and disadvantaged populations.
E6.16: Encourage the use of bicycles through support of bike share opportunities, community
bike programs, and the provision of bicycle parking opportunities such as bike racks and
bike lockers.
E6.A.1: Continue to limit exposure to secondhand smoke by encouraging the creation of smoke
free spaces and facilities in public spaces, and at all workplaces and multi-unit housing.
2.3 Regional and Local Air Quality Conditions
2.3.1 San Diego Air Basin Attainment Designation
Pursuant to the 1990 federal CAA amendments, the EPA classifies air basins (or portions thereof) as
“attainment” or “nonattainment” for each criteria air pollutant, based on whether the NAAQS have
been achieved. Generally, if the recorded concentrations of a pollutant are lower than the standard,
the area is classified as “attainment” for that pollutant. If an area exceeds the standard, the area is
classified as “nonattainment” for that pollutant. If there is not enough data available to determine
whether the standard is exceeded in an area, the area is designated as “unclassified” or
“unclassifiable.” The designation of “unclassifiable/attainment” means that the area meets the
standard or is expected to be meet the standard despite a lack of monitoring data. Areas that achieve
the standards after a nonattainment designation are redesignated as maintenance areas and must have
approved Maintenance Plans to ensure continued attainment of the standards. The California Clean
Air Act, like its federal counterpart, called for the designation of areas as “attainment” or
“nonattainment,” but based on CAAQS rather than the NAAQS. Table 2 depicts the current
attainment status of the project site with respect to the NAAQS and CAAQS. The attainment
classifications for the criteria pollutants are outlined in Table 2.

Notes:
Attainment = meets the standards; Attainment/maintenance = achieve the standards after a non attainment designation; Nonattainment =
does not meet the standards; Unclassified or Unclassifiable = insufficient data to classify; Unclassifiable/attainment = meets the standard or is
expected to be meet the standard despite a lack of monitoring data.
If nonattainment for Federal Standards, a clarifying classification will be provided indicating the severity of the nonattainment status.
a The federal 1-hour standard of 0.12 parts per million was in effect from 1979 through June 15, 2005. The revoked standard is referenced
here, because it was employed for such a long period and because this benchmark is addressed in State Implementation Plans.
b Federal designations for SO2 are on hold by the Environmental Protection Agency; Environmental Protection Agency expects to make the
designations by December 2017 (EPA 2016d).
In summary, the SDAB is designated as an attainment area for the 1997 8-hour O3 NAAQS and as
a nonattainment area for the 2008 8-hour O3 NAAQS. The SDAB is designated as a nonattainment
area for O3, PM10, and PM2.5 CAAQS. The portion of the SDAB where the Project is located is
designated as attainment or unclassifiable/unclassified for all other criteria pollutants under the
NAAQS and CAAQS.
2.3.2 Local Ambient Air Quality
CARB, air districts, and other agencies monitor ambient air quality at approximately 250 air quality
monitoring stations across the state. Local ambient air quality is monitored by the SDAPCD. The
SDAPCD operates a network of ambient air monitoring stations throughout San Diego County,
which measure ambient concentrations of pollutants and determine whether the ambient air quality
meets the CAAQS and the NAAQS. The nearest SDAPCD-operated monitoring station is the Chula
Vista monitoring station, which is located approximately 1 mile south of the Project site. This site
was used to show the background ambient air quality for O3, PM10, PM2.5, and NO2. The closest
monitoring site that measures CO is the Beardsley Street monitoring station in San Diego, which is
about 6 miles northwest of the Project. The closest monitoring site that measures SO2 is the Floyd
Smith Drive monitoring station in El Cajon, which is about 13 miles northeast of the Project. The
most recent background ambient air quality data and number of days exceeding the ambient air
quality standards from 2014 to 2016 are presented in Table 3.

Daily exceedances for particulate matter are estimated days because PM10 and PM2.5 are not monitored daily. All other criteria pollutants did
not exceed federal or state standards during the years shown. There is no federal standard for 1-hour O3, annual PM10, or 24-hour SO2, nor is
there a state 24-hour standard for PM2.5.
a Measurements of PM10 and PM2.5 are usually collected every 6 days and every 1 to 3 days, respectively. Number of days exceeding the
standards is a mathematical estimate of the number of days concentrations would have been greater than the level of the stand ard had
each day been monitored. The numbers in parentheses are the measured number of samples that exceeded the standard.

2.4 Significance Criteria and Methodology
2.4.1 Thresholds of Significance
The significance criteria used to evaluate the project impacts to air quality is based on the
recommendations provided in Appendix G of the California Environmental Quality Act (CEQA)
Guidelines. For the purposes of this air quality analysis, a significant impact would occur if the
project would (14 CCR 15000 et seq.):
1. Conflict with or obstruct implementation of the applicable air quality plan.
2. Violate any air quality standard or contribute substantially to an existing or projected air
quality violation.
3. Result in a cumulatively considerable net increase of any criteria pollutant for which
t he project region is non -attainment under an applicable federal or state ambient air
quality standard (including releasing emissions that exceed quantitative thresholds for
ozone precursors ).
4. Expose sensitive receptors to substantial pollutant concentrations.
5. Create objectionable odors affecting a substantial number of people.
Appendix G of the CEQA Guidelines (14 CCR 15000 et seq.) indicates that, where available, the
significance criteria established by the applicable air quality management district or air pollution
control district may be relied upon to determine whether the project would have a significant
impact on air quality.
The City of Chula Vista evaluated project emissions based on the quantitative emission
thresholds established by the SCAQMD. The SCAQMD sets forth quantitative emission
significance thresholds below which a project would not have a significant impact on ambient air
quality. It should be noted that the use of these significance thresholds is conservative, as the
SCAQMD’s significance thresholds were originally based on the SCAB extreme ozone
nonattainment status for the 1-hour NAAQS, whereas the SDAB was designated as an attainment
area for the 1-hour NAAQS. Project-related air quality impacts estimated in this environmental
analysis would be considered significant if any of the applicable significance thresholds
presented in Table 4 are exceeded.

GHG emissions thresholds for industrial projects, as added in the March 2015 revision to the SCAQMD Air Quality Significance Thresholds,
were not include included in Table 4 as they will be addressed within the GHG emissions analysis and not the air quality study.
a The phaseout of leaded gasoline started in 1976. Since gasoline no longer contains lead, the project is not anticipated to re sult in impacts
related to lead; therefore, it is not discussed in this analysis.
The thresholds listed in Table 4 represent screening-level thresholds that can be used to evaluate
whether Project-related emissions could cause a significant impact on air quality. Emissions
below the screening-level thresholds would not cause a significant impact. For nonattainment
pollutants, if emissions exceed the thresholds shown in Table 4, the Project could have the
potential to result in a cumulatively considerable net increase in these pollutants and, thus, could
have a significant impact on the ambient air quality.
With respect to odor s, SDAPCD Rule 51 (Public Nuisance) prohibits emission of any
material that causes nuisance to a considerable number of persons or endangers the comfort,
health, or safety of any person. A project that proposes a use that would produce
objectionable odors would be deemed to have a significant odor impact if it would affect a
considerable number of off -site receptors.

As described in Section 1.2, Project Description, the Project would develop a 170-unit
apartment complex on 5.29 acres. For the purposes of modeling, it was assumed that
construction of the Project would commence in October 2018 and would last approximately 21
months, ending in July 2020. The analysis contained herein is based on the assumptions outlined in
Table 5 (duration of phases is approximate). The Project schedule was based on information
provided by the Project applicant.

Each phase was broken into several subphases for modeling purposes. The equipment and vehicles included herein represents the aggregate
of all subphases.
For the analysis, it was generally assumed that heavy construction equipment would be operating
at the site for approximately 8 hours per day, 5 days per week (22 days per month) during Project
construction. The Project applicant provided construction worker trip estimates. There were
hauling trips for the Project to account for soil import and export. The total area graded for the
Project was estimated at 7.5 acres.
Construction of Project components would be subject to SDAPCD Rule 55, Fugitive Dust
Control. This rule requires that construction of Project components include steps to restrict
visible emissions of fugitive dust beyond the property line (SDAPCD 2009b). Compliance with
Rule 55 would limit fugitive dust (PM10 and PM2.5) that may be generated during grading and
construction activities.
A detailed depiction of the construction schedule—including information regarding subphases
and equipment used during each subphase—is included in Appendix A of this report. The
information contained in Appendix A was used as CalEEMod model inputs.
2.4.2.2 Operation
Emissions from the operational phase of the Project were estimated using CalEEMod. Operational
year 2021 was assumed as it would be the first full year following completion of construction.
Area Sources
CalEEMod was used to estimate operational emissions from area sources, including emissions
from consumer product use, architectural coatings, and landscape maintenance equipment.
Emissions associated with natural gas usage in space heating and water heating are calculated in
the building energy use module of CalEEMod, as described in the following text.
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
32 December 2018
Consumer products are chemically formulated products used by household and institutional
consumers, including detergents; cleaning compounds; polishes; floor finishes; cosmetics;
personal care products; home, lawn, and garden products; disinfectants; sanitizers; aerosol
paints; and automotive specialty products. Other paint products, furniture coatings, or
architectural coatings are not considered consumer products (CAPCOA 2017). Consumer
product VOC emissions are estimated in CalEEMod based on the floor area of buildings and on
the default factor of pounds of VOC per building square foot per day. The CalEEMod default
values for consumer products were assumed.
VOC off-gassing emissions result from evaporation of solvents contained in surface coatings,
such as in paints and primers used during building maintenance. CalEEMod calculates the VOC
evaporative emissions from the application of surface coatings based on the VOC emission
factor, the building square footage, the assumed fraction of surface area, and the reapplication
rate. The VOC emissions factor is based on the VOC content of the surface coatings, and
SDAPCD’s Rule 67.0.1 (Architectural Coatings) governs the VOC content for interior and
exterior coatings. This rule requires manufacturers, distributors, and end users of architectural
and industrial maintenance coatings to reduce VOC emissions from the use of these coatings,
primarily by placing limits on the VOC content of various coating categories (SDAPCD 2015 a).
The Project would use architectural coatings that would not exceed 150 grams per liter (g/L) for
interior or for exterior applications. The model default reapplication rate of 10% of area per year
is assumed. Consistent with CalEEMod defaults, it is assumed that the surface area for painting
equals 2.7 times the floor square footage, with 75% assumed for inter ior coating and 25%
assumed for exterior surface coating (CAPCOA 2017). CalEEMod defaults were assumed for the
application of architectural coatings during operation, as that would not be controlled by the
Project applicant.
Landscape maintenance includes fuel combustion emissions from equipment such as lawn
mowers, rototillers, shredders/grinders, blowers, trimmers, chainsaws, and hedge trimmers.
The emissions associated with landscape equipment use are estimated based on CalEEMod
default values for emissi on factors (grams per square foot of building space per day) and
number of summer days (when landscape maintenance would generally be performed) and
winter days. For San Diego County, the average annual number of summer days is es timated at
180 days (CAPCOA 2017).
Energy Sources
As represented in CalEEMod, energy sources include emissions associated with building electricity
and natural gas usage. Electricity use would contribute indirectly to criteria air pollutant emissions;
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
33 December 2018
however, the emissions from electricity use are only quantified for GHGs in CalEEMod, since
criteria pollutant emissions occur at the site of the power plant, which is typically off site.
The Project would incorporate solar photovoltaic panels on site to cover the electricity needs of all
common area lighting. The Project would also include Energy Star appliances, electronic vehicle
charging stations, and 100% light emitting diode lighting fixtures for interior and exterior.
Mobile Sources
Following the completion of construction activ ities, the Project would generate criteria
pollutant emissions from mobile sources (vehicular traffic) as a result of the residents from the
Project. The daily vehicle miles traveled and maximum weekday trip rates were taken from the
Traffic Impact Analysi s for the Project (Chen Ryan 2017). The maximum weekday trip rates
from the Traffic Impact Analysis are 1,020 one -way trips per day. The estimated trip lengths
and trip modes were based on CalEEMod defaults , which are 10.8 miles for home to work trips
(41.6%), 7.3 miles for home to shop trips (18.8%), and 7.5 miles for home to other trips
(39.6%) (CAPCOA 2017). The CalEEMod model was used to estimate emissions from
proposed vehicular sources (refer to Appendix A). CalEEMod default data, including
temperature, trip characteristics, variable start information, emissions factors, and trip
distances, were conservatively used for the model inputs. Project -related traffic was assumed
to include a mixture of vehicles in accordance with the associated use, light -duty vehicles for
the office staff and heavy-duty vehicles for the vendor trucks. Emission factors representing
the vehicle mix and emissions for 2021 were conservatively used to estimate emissions
associated with vehicular sources.
Health Risk Assessment
As required by Policy E 6.10 in the City’s General Plan Environmental Element, the siting of
new sensitive receivers within 500 feet of highways resulting from development or
redevelopment projects shall require the preparation of an HRA as part of the CEQA review of the
project. This report includes an HRA associated with emissions from the 805 freeway based on the
methodologies prescribed in the Office of Environmental Health Hazard Assessment (OEHHA) Air
Toxics Hot Spots Program Risk Assessment Guidelines – Guidance Manual for Preparation of
Health Risk Assessments (OEHHA 2015). To implement the OEHHA Guidelines based on Project
information, the SDAPCD has developed a three-tiered approach where each successive tier is
progressively more refined, with fewer conservative assumptions. The SDAPCD Supplemental
Guidelines for Submission of Air Toxics “Hot Spots” Program Health Risk Assessments provides
guidance with which to perform HRAs within the SDAB (SDAPCD 2015b).
Air Quality and Greenhouse Gas Emissions Analysis

Health effects from carcinogenic air toxics are usually described in terms of cancer risk. The
SDAPCD recommends a carcinogenic (cancer) risk threshold of 10 in a million. Additionally,
some TACs increase non-cancer health risk due to long-term (chronic) exposures. The Chronic
Hazard Index is the sum of the individual substance chronic hazard indices for all TACs
affecting the same target organ system. The SDAPCD recommends a Chronic Hazard Index
significance threshold of 1.0 (project increment). The exhaust from diesel engines is a complex
mixture of gases, vapors, and particles, many of which are known human carcinogens. DPM has
established cancer risk factors and relative exposure values for long-term chronic health hazard
impacts. No short-term, acute relative exposure level has been established for DPM; therefore,
acute impacts of DPM are not addressed in this assessment. This HRA evaluated the risk to future
residents from TAC emissions from gasoline and diesel vehicles from the nearby 805 freeway.
The dispersion modeling of vehicle emissions was performed using the American
Meteorological Society/EPA Regulatory Model (AERMOD), which is the model SDAPCD
requires for atmospheric dispersion of emissions. AERMOD is a steady-state Gaussian plume
model that incorporates air dispersion based on planetary boundary layer turbulence structure
and scaling concepts, including treatment of surface and elevated sources, building downwash,
and simple and complex terrain (EPA 2015). For the Project, AERMOD was run with all sources
emitting unit emissions (1 gram per second) to obtain the “Χ/Q” values. Χ/Q is a dispersion
factor that is the average effluent concentration normalized by source strength and is used as a
way to simplify the representation of emissions from many sources. The Χ/Q values of ground-
level concentrations were determined for freeway emissions using AERMOD and the maximum
concentrations determined for the 1-hour and Period averaging periods. Principal parameters of
this modeling are presented in Table 7.
Table 7
AERMOD Principal Parameters
Parameter Details
Meteorological Data The latest 3-year meteorological data (2010–2012) for the Chula Vista Station from SDAPCD were
downloaded and then input to AERMOD (Gould pers. comm. 2017). For cancer or chronic noncancer
risk assessments, the average cancer risk of all years modeled was used.
Urban versus Rural
Option
Urban areas typically have more surface roughness, as well as structures and low-albedo surfaces
that absorb more sunlight—and thus more heat—relative to rural areas. However, based on the
SDAPCD guidelines, the rural dispersion option was selected due to the Project’s proximity to the
ocean.
Terrain Characteristics The terrain in the vicinity of the modeled Project site is generally flat. The elevation of the modeled
site is about 29 meters above sea level. Digital elevation model files were imported into AERMOD so
that complex terrain features were evaluated as appropriate.
Elevation Data Digital elevation data were imported into AERMOD, and elevations were assigned to the emission
sources and receptors. Digital elevation data were obtained through AERMOD View in the United
States Geological Survey’s National Elevation Dataset format with a 10-meter resolution.

Air dispersion modeling of the 805 freeway was conducted using emissions estimated using CT-
EMFAC2014, conservatively assuming emissions would occur 24 hours per day, 365 days per year.
The Project area was modeled as two line volume sources, one source representing southbound
traffic and one representing northbound traffic.
Source Release
Characterizations
For modeling operational emissions dispersion using AERMOD, it was assumed that the total site
area would operate over a 70-year period.
Discrete Receptors A uniform Cartesian grid overlaying the project site with 20-meter resolution was converted into discrete
Cartesian receptors to represent future residents’ on site.
Note: See Appendix B.
Dispersion model plotfiles from AERMOD were then imported into CARB’s Hotspots Analysis
and Reporting Program Version 2 to determine health risk, which requires peak 1-hour emission
rates and annual-averaged emission rates for all pollutants for each modeling source. For the
residential health risk, the HRA assumes exposure would start in the third trimester of
pregnancy. Based on the HRA included in Appendix B, the maximally exposed individual resident
would be located at the northeastern corner of the Project site. The results of the HRA are provided
in Section 2.5.4, and detailed results and methodology are provided in Appendix B.
2.5 Impact Analysis
2.5.1 Would the project conflict with or obstruct implementation of the
applicable air quality plan?
As mentioned in Section 2.2.3, Local Regulations, the SDAPCD and SANDAG are responsible for
developing and implementing the clean air plans for attainment and maintenance of the ambient air
quality standards in the basin—specifically, the SIP and RAQS.3 The federal O3 maintenance plan,
which is part of the SIP, was adopted in 2012. The most recent O3 attainment plan was adopted in
2016. The SIP includes a demonstration that current strategies and tactics will maintain acceptable
air quality in the SDAB based on the NAAQS. The RAQS was initially adopted in 1991 and is
updated on a triennial basis (most recently in 2016). The RAQS outlines SDAPCD’s plans and
control measures designed to attain the state air quality standards for O3. The SIP and RAQS rely
on information from CARB and SANDAG, including mobile and area source emissions, as well as
information regarding projected growth in the County as a whole and the cities in the County, to
3 For the purpose of this discussion, the relevant federal air quality plan is the ozone maintenance plan (SDAPCD
2012). The RAQS is the applicable plan for purposes of state air quality planning. Both plans reflect growth
projections in the SDAB .
Air Quality and Greenhouse Gas Emissions Analysis

project future emissions and determine the strategies necessary for the reduction of emissions
through regulatory controls. CARB mobile source emission projections and SANDAG growth
projections are based on population, vehicle trends, and land use plans developed by the County
and the cities in the County as part of the development of their general plans.
If a project proposes development that is greater than that anticipated in the local plan and
SANDAG’s growth projections, the project might be in conflict with the SIP and RAQS and
may contribute to a potentially significant cumulative impact on air quality. The Project is
within the Bonita Glen Specific Plan, which was originally approved in 1977 and provides for
the long-term development of a variety of commercial and residential land uses. The Project is
consistent with the land-use zoning for the site.
Implementation of the Project would result in an increase in 170 apartments. The City’s
housing is projected to grow from 79,255 in 2012 to 89,176 in 2020, 101,188 in 2035, and
108,273 in 2050 (SANDAG 2013). The SANDAG projections assume an annual increase of
1,240 units between 2012 and 2020, 801 units between 2020 and 2035, and 472 units between
2035 and 2050. The Project will bring the 170 units into operation in 2021. The additional 170
units is within the projected annual increase of 801 housing units per year. Therefore, the
Project would be consistent with SANDAG projections.
While the SDAPCD and City do not provide guidance regarding the analysis of impacts
associated with air quality plan conformance, the County’s Guidelines for Determining
Significance and Report and Format and Content Requirements – Air Quality does discuss
conformance with the RAQS (County of San Diego 2007). The guidance indicates that if a
project, in conjunction with other projects, contributes to growth projections that would not
exceed SANDAG’s growth projections for the City, the project would not be in conflict with
the RAQS (County of San Diego 2007). As previously discussed, this Project would not
contribute to growth in the region that is not already accounted for. Therefore, impacts would
be considered less than significant .
Mitigation Measures
No mitigation is required.
Level of Significance After Mitigation
The Project is less than significant prior to mitigation.

2.5.2 Would the project violate any air quality standard or contribute
substantially to an existing or projected air quality violation?
Construction Emissions
Construction of the Project would result in the temporary addition of pollutants to the local
airshed caused by on-site sources (i.e., off-road construction equipment, soil disturbance, and
VOC off-gassing) and off-site sources (worker vehicle trips). Construction emissions can vary
substantially day to day, depending on the level of activity, the specific type of operation, and for
dust, the prevailing weather conditions.
Criteria air pollutant emissions associated with construction activity were quantified using
CalEEMod. Default values provided by the program were used where detailed Project
information was not available. A detailed depiction of the construction schedule—including
information regarding phasing, equipment used during each phase, haul trucks, vendor trucks,
and worker vehicles—is included in Section 2.4.2.1. The information contained in Appendix A
was used as CalEEMod inputs.
Implementation of the Project would generate air pollutant emissions from entrained dust, off-road
equipment, vehicle emissions, and asphalt pavement application. Entrained dust results from the
exposure of earth surfaces to wind from the direct disturbance and movement of soil, resulting in
PM10 and PM2.5 emissions. The Project is subject to SDAPCD Rule 55, Fugitive Dust Control.
This rule requires that the Project take steps to restrict visible emissions of fugitive dust beyond the
property line. Compliance with Rule 55 would limit fugitive dust (PM10 and PM2.5) generated
during grading and construction activities. To account for dust control measures in the calculations,
it was assumed that the active sites would be watered at least two times daily, resulting in an
approximately 55% reduction of particulate matter.
Exhaust from internal combustion engines used by construction equipment and worker vehicles
would result in emissions of VOC, NOx, CO, SOx, PM10, and PM2.5. The application of asphalt
pavement and architectural coatings would also produce VOC emissions.
Table 8 shows the estimated maximum daily construction emissions associated with construction
of the Project without mitigation. Complete details of the emissions calculations are provided in
Appendix A of this document.

The values shown are the maximum summer or winter daily emissions results from California Emissions Estimator Model. Although not
considered mitigation, these emissions reflect California Emissions Estimator Model “mitigated” output, which accounts for the required
compliance with SDAPCD Rule 55 (Fugitive Dust) and Rule 67.0.1 (Architectural Coatings).
As shown in Table 8, daily construction emissions would not exceed the significance thresholds for
any criteria air pollutant. Therefore, impacts during construction would be less than significant.
Operational Emissions
Operation of the Project would generate VOC, NOx, CO, SOx, PM10, and PM2.5 emissions from
mobile sources, including vehicle trips; area sources, including the use of consumer products,
and landscape maintenance equipment; and energy sources. As discussed in Section 2.4.2.2,
Operation, pollutant emissions associated with long-term operations were quantified using
CalEEMod. Project-generated mobile source emissions were estimated in CalEEMod based on
Project-specific trip rates. CalEEMod default values were used to estimate emissions from the
Project area and energy sources.
Table 9 presents the maximum daily area, energy, and mobile source emissions associated
with operation (Year 2021) of the Project. The values shown are the maximum summer or
winter daily emissions results from CalEEMod. Details of the emission calculations are

The values shown are the maximum summer or winter daily emissions results from California Emissions Estimator Model. These emissions
reflect California Emissions Estimator Model “mitigated” output, which accounts for compliance with SDAPCD Rule 55 (Fugitive Dust) and Rule
67.0.1 (Architectural Coatings).
As shown in Table 9, the combined daily area, energy, and mobile source emissions would not
exceed the SDAPCD’s operational thresholds for VOC, NO x, CO, SOx, PM10, and PM2.5.
Impacts associated with Project-generated operational criteria air pollutant emissions would be
less than significant.
Mitigation Measures
No mitigation is required.
Level of Significance After Mitigation
The Project would have a less-than-significant impact prior to mitigation.
2.5.3 Would the project result in a cumulatively considerable net increase of any
criteria pollutant for which the project region is non-attainment under an
applicable federal or state ambient air quality standard (including releasing
emissions which exceed quantitative thresholds for ozone precursors)?
Air pollution is largely a cumulative impact. The nonattainment status of regional pollutants is a
result of past and present development, and the SDAPCD develops and implements plans for
future attainment of ambient air quality standards. Based on these considerations, project -level
thresholds of significance for criteria pollutants are relevant in the determination of whether a
project’s individual emissions would have a cumulatively significant impact on air quality. As
described under Section 2.5.2, the Project would have a less-than-significant impact for short-
term construction and long-term operations.
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
40 December 2018
The SDAB is a nonattainment area for O3 under the NAAQS and CAAQS. The poor air quality
in the SDAB is the result of cumulative emissions from motor vehicles, off-road equipment,
commercial and industrial facilities, and other emission sources. Projects that emit these
pollutants or their precursors (i.e., VOCs and NOx for O3) potentially contribute to poor air
quality. In analyzing cumulative impacts from a project, the analysis must specifically evaluate
the project’s contribution to the cumulative increase in pollutants for which the SDAB is
designated as nonattainment for the CAAQS and NAAQS. If the project does not exceed
thresholds and is determined to have less-than-significant project-specific impacts, it may still
contribute to a significant cumulative impact on air quality if the emissions from the project, in
combination with the emissions from other proposed or reasonably foreseeable future projects,
are in excess of established thresholds. However, a project would only be considered to have a
significant cumulative impact if the project’s contribution accounts for a significant proportion of
the cumulative total emissions (i.e., it represents a “cumulatively considerable contribution” to
the cumulative air quality impact).
Additionally, for the SDAB, the RAQS serves as the long-term regional air quality planning
document for the purpose of assessing cumulative operational emissions in the basin to ensure
the SDAB continues to make progress toward NAAQS- and CAAQS-attainment status. As such,
cumulative projects located in the San Diego region would have the potential to result in a
cumulative impact to air quality if, in combination, they would conflict with or obstruct
implementation of the RAQS. Similarly, individual projects that are inconsistent with the
regional planning documents upon which the RAQS is based would have the potential to result
in cumulative operational impacts if they represent development and population increases
beyond regional projections.
The SDAB has been designated as a federal nonattainment area for O3 and a state nonattainment area
for O3, PM10, and PM2.5. The nonattainment status is the result of cumulative emissions from all
sources of these air pollutants and their precursors within the basin. As discussed previously, the
Project would not exceed significance thresholds during construction or operation. As such, the
Project would result in less-than-significant impacts to air quality relative to emissions.
Regarding long-term cumulative operational emissions in relation to consistency with local air
quality plans, the SIP and RAQS serve as the primary air quality planning documents for the
state and SDAB, respectively. The SIP and RAQS rely on SANDAG growth projections based
on population, vehicle trends, and land use plans developed by the cities and the County as part
of the development of their general plans. Therefore, projects that propose development that is
consistent with the growth anticipated by local plans would be consistent with the SIP and RAQS
and would not be considered to result in cumulatively considerable impacts from operational
emissions. As stated previously, the Project would be consistent with the existing zoning and land
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
41 December 2018
use designation for the site and would not result in significant regional growth that is not accounted
for within the RAQS. As a result, the Project would not result in a cumulatively considerable
contribution to regional O3 concentrations or other criteria pollutant emissions. Cumulative impacts
would be less than significant during operation.
Mitigation Measures
No mitigation is required.
Level of Significance After Mitigation
The Project would have a less-than-significant impact prior to mitigation.
2.5.4 Would the project expose sensitive receptors to substantial
pollutant concentrations?
Air quality varies as a direct function of the amount of pollutants emitted into the atmosphere,
the size and topography of the air basin, and the prevailing meteorological conditions. Air quality
problems arise when the rate of pollutant emissions exceeds the rate of dispersion. Reduced
visibility, eye irritation, and adverse health impacts upon those persons termed “sensitive
receptors” are the most serious hazards of existing air quality conditions in the area. Some land
uses are considered more sensitive to changes in air quality than others, depending on the
population groups and the activities involved. People most likely to be affected by air pollution,
as identified by CARB, include children, the elderly, athletes, and people with cardiovascular
and chronic respiratory diseases. As such, sensitive receptors include residences, schools,
playgrounds, child-care centers, athletic facilities, long-term health-care facilities, rehabilitation
centers, convalescent centers, and retirement homes. The closest sensitive receptors to the Project
are residences adjacent to the western and eastern property boundaries. The Project would also
introduce new on-site sensitive receptors to the area.
Health Impacts of Toxic Air Contaminants
“Incremental cancer risk” is the net increased likelihood that a person continuously exposed to
concentrations of TACs resulting from a project over a 9-, 30-, and 70-year exposure period
would contract cancer based on the use of standard OEHHA risk-assessment methodology
(OEHHA 2015). In addition, some TACs have non-carcinogenic effects. TACs that would
potentially be emitted during construction activities would be DPM emitted from heavy-duty
construction equipment and heavy-duty trucks. Heavy-duty construction equipment and diesel
trucks are subject to CARB ATCMs to reduce DPM emissions. According to the OEHHA, HRAs
should be based on a 30-year exposure duration based on typical residency period; however, such
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
42 December 2018
assessments should be limited to the period/duration of activities associated with the project
(OEHHA 2015). Thus, the duration of proposed construction activities (approximately 21 months)
would only constitute a small percentage of the total long-term exposure period and would not
result in exposure of proximate sensitive receptors to substantial TACs.
As required by Policy E 6.10 in the City’s General Plan Environmental Element (City of Chula
Vista 2005), the siting of new sensitive receivers within 500 feet of highways resulting from
development or redevelopment projects shall require the preparation of an HRA as part of the
CEQA review of the project. The Project is less than 300 feet from the 805 freeway and , thus, is
subject to this requirement. The duration of exposure from the 805 freeway was assumed to be
24 hours per day, 365 days per week over 9, 30, and 70 years. The HRA methodology was
further described in Section 2.4.2.2, and the detailed assessment is provided in Appendix B. The
results of the HRA for TAC emissions from the 805 freeway on future residents are summarized
in Table 10.

The results of the operational HRA demonstrate that the TAC exposure from roadway emissions
generated by the 805 freeway would result in cancer risk on site above the 10 in 1 million threshold.
Therefore, TAC emissions from operation of the Project may result in a potentially significant impact
and mitigation is required.
Health Impacts of Carbon Monoxide
Mobile-source impacts occur on two basic scales of motion. Regionally, Project-related travel
will add to regional trip generation and increase the vehicle miles traveled (VMT) within the
local airshed and the SDAB. Locally, Project traffic will be added to the City’s roadway system.
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
43 December 2018
If such traffic occurs during periods of poor atmospheric ventilation, consists of a large number
of vehicles “cold-started” and operating at pollution-inefficient speeds, and operates on roadways
already crowded with non-project traffic, there is a potential for the formation of microscale CO
“hotspots” in the area immediately around points of congested traffic. Because of continued
improvement in mobile emissions at a rate faster than the rate of vehicle growth and/or
congestion, the potential for CO hotspots in the SDAB is steadily decreasing.
Projects contributing to adverse traffic impacts may result in the formation of CO hotspots. To
verify that the Project would not cause or contribute to a violation of the CO standard, a
screening evaluation of the potential for CO hotspots was conducted. A traffic impact analysis
evaluated the level of service (LOS) (i.e., increased congestion) impacts at intersections affected
by the Project (Chen Ryan 2017). The potential for CO hotspots was evaluated based on the
results of the traffic report. As the City does not have CO hotspot guidelines, the County of San
Diego’s Guidelines (County of San Diego 2007) CO hotspot screening guidance was followed to
determine if the Project would require a site-specific hotspot analysis. The County recommends
that a quantitative analysis of CO hotspots be performed for intersections operating at or below a
LOS of “E” and have peak-hour trips exceeding 3,000 trips. The Project’s traffic impact analysis
determined that there would be no intersections that would operate at a LOS E or lower with the
Project (Chen Ryan 2017). Therefore, a quantitative analysis is not required for the Project. In
addition, because of continued improvement in vehicular emissions at a rate faster than the rate of
vehicle growth and/or congestion, the potential for CO hotspots in the SDAB is steadily
decreasing. Background CO levels in the area, as shown in Table 3, Ambient Air Quality Data, are
less than 20% of the 1- and 8-hour CAAQS and would be expected to improve further due to
reductions in motor vehicle emissions. Based on these considerations, Project operation would
result in a less-than-significant impact to air quality with regard to potential CO hotspots.
Health Impacts of Other Criteria Air Pollutants
Construction and operation of the Project would not result in emissions that exceed the
SDAPCD’s emission thresholds for any criteria air pollutants. Regarding VOCs, some VOCs
would be associated with motor vehicles and construction equipment, while others are associated
with architectural coatings, the emissions of which would not result in the exceedances of the
SDAPCD’s thresholds. Generally, the VOCs in architectural coatings are of relatively low
toxicity. Additionally, SDAPCD Rule 67.0.1 restricts the VOC content of coatings for both
construction and operational applications.
In addition, VOCs and NOx are precursors to O3, for which the SDAB is designated as
nonattainment with respect to the NAAQS and CAAQS (the SDAB is designated by the EPA as
an attainment area for the 1-hour O3 NAAQS standard and 1997 8-hour NAAQS standard). The
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
44 December 2018
health effects associated with O3, as discussed in Section 2.1.2, are generally associated with
reduced lung function. The contribution of VOCs and NOx to regional ambient O3 concentrations
is the result of complex photochemistry. The increases in O3 concentrations in the SDAB due to
O3 precursor emissions tend to be found downwind from the source location to allow time for the
photochemical reactions to occur. However, the potential for exacerbating excessive O3
concentrations would also depend on the time of year that the VOC emissions would occur,
because exceedances of the O3 AAQS tend to occur between April and October when solar
radiation is highest.
The holistic effect of a single project’s emissions of O3 precursors is speculative due to the lack
of quantitative methods to assess this impact. Nonetheless, the VOC and NOx emissions
associated with Project construction and operations could minimally contribute to regional O3
concentrations and the associated health impacts. Due to the minimal contribution during
construction and operation, as well as the existing good air quality in Coastal San Diego areas,
health impacts would be considered less than significant.
Regarding NO2, according to the construction emissions analysis, construction of the Proposed
Project would not contribute to exceedances of the NAAQS and CAAQS for NO2. As described
in Section 2.1.2, NO2 and NOx, health impacts are associated with respiratory irritation, which
may be experienced by nearby receptors during the periods of heaviest use of off-road
construction equipment. However, these operations would be relatively short term. Additionally,
off-road construction equipment would operate at various portions of the site and would not be
concentrated in one portion of the site at any one time. Construction of the proposed Project
would not require any stationary emission sources that would create substantial, localized NOx
impacts. Therefore, health impacts would be considered less than significant.
The VOC and NOx emissions, as described previously, would minimally contribute to regional
O3 concentrations and its associated health effects. In addition to O3, NOx emissions would not
contribute to potential exceedances of the NAAQS and CAAQS for NO2. As shown in Table 3,
the existing NO2 concentrations in the area are well below the NAAQS and CAAQS standards.
Thus, it is not expected that the Project’s operational NOx emissions would result in exceedances
of the NO2 standards or contribute to the associated health effects. CO tends to be a localized
impact associated with congested intersections. The associated CO “hotspots” were discussed
previously as a less-than-significant impact. Thus, the proposed Project’s CO emissions would not
contribute to significant health effects associated with this pollutant. PM10 and PM2.5 would not
contribute to potential exceedances of the NAAQS and CAAQS for particulate matter, would not
obstruct the SDAB from coming into attainment for these pollutants, and would not contribute to
significant health effects associated with particulates.
Air Quality and Greenhouse Gas Emissions Analysis

Based on the preceding considerations, health impacts associated with criteria air pollutants would
be considered less than significant.
Mitigation Measures
Consistent with SDAPCD guidance, mitigation measures were evaluated to identify ways to
ensure that residents of the proposed project would not be exposed to health risks that exceed
SDAPCD’s significance thresholds and to ensure that impacts related to community risk and
hazards from placement of sensitive receptors proximate to major sources of air pollution would
be less than significant.
The US EPA reported that the Minimum Efficiency Reporting Value (MERV) 13 filters remove
90% of particles ranging from 1 to 10 microns (EPA 2018). For this analysis, Dudek assumed an
90% particulate matter reduction for the air filters. No reduction in pollutant concentrations due
to the use of filters was applied to gaseous TACs such as benzene, toluene, and formaldehyde.
The National Human Activity Pattern Survey (NHAPS) was conducted in support by the US
EPA to study where people spend their time. The results of the NHAPS showed that on average
people spend 87% of their time in enclosed buildings and 6% of their time in enclosed vehicles
(Kleipeis et. al. 2001). This assessment of risk with mitigation includes the accounting for time
spent indoors as identified in the NHAPS and the time spent away from home as recommended
by OEHHA (OEHHA 2015). Accounting for the actual time spent indoors and exposure related
to the residents within the project provides a more realistic exposure scenario from TAC
emissions from the 805 freeway.
Studies have shown that vegetative landscaping can reduce particulate emissions by up to 65% to
85% at lower wind speeds, with greater removal rates expected for ultra-fine particles < 0.1 μm
in diameter. The effectiveness of PM removal via tree plantings depends on characteristics of the
species chosen (e.g., foliage surface, canopy structure, and life span) and varies by particulate
size (Fujii et al. 2008, Miller et al. 2009, SMAQMD 2011). Mitigation measure MM-HR-4 has
been provided to further reduce impacts related to particulates; however, emission reductions
from installation of tiered vegetative landscaping as described in MM-HR-4 was not quantified
for the purposes of impact determination because MM-HR-1 through MM-HR-3 mitigate
impacts to particulate exposure to a level that is less than significant.
The following mitigation measures would reduce the significant impacts associated with cancer
risk levels below the SDAPCD thresholds:
MM-HR-1 Prior to the issuance of the first building permit, the applicant or its successor
shall require the installation of high-efficiency return air filters on all heating,
Air Quality and Greenhouse Gas Emissions Analysis

ventilation, and air conditioning (HVAC) systems serving the project. This
requirement shall be noted on the project’s architectural plan. The air filtration
system shall reduce at least 90% of particulate matter emissions, such as can be
achieved with a Minimum Efficiency Reporting Value 13 (MERV 13) air
filtration system installed on return vents in residential units. The property
management for the project shall maintain the air filtration system on any HVAC
system installed for the specified residential units in accordance with the
manufacturer’s recommendations for the life of the project.
MM-HR-2 Prior to the issuance of the first building permit, t he applicant or its successor
shall locate air intake vents on the residential buildings such that they do not
face the 805 freeway and are as far from 805 freeway as practicable. This
requirement shall be noted on the project’s architectural plans.
MM-HR-3 Prior to issuance of the first certificate of occupancy, a City-approved, ASHRAE
certified specialist shall verify the implementation of the installation of high-
efficiency air filtration systems on return vents to reduce ambient particulate matter
concentrations prior to occupancy of the residential units. On-going maintenance of
the installed filtration systems shall be the responsibility of the applicant or its
successor. The City may enforce that the systems are in accordance with the
manufacturer’s recommendations for the life of the project.
MM-HR-4 As part of landscape design and vegetation palette for the project, installation of
tiered vegetative landscaping is encouraged, including the installation of
evergreen trees, between the 805 freeway and the project. Any vegetation selected
shall be compatible with the proposed project Fire Protection Plan. The tiered
vegetation shall be maintained as part of the residential community landscaping
areas where feasible.
Level of Significance After Mitigation
Implementing Mitigation Measures MM-HR-1, MM-HR-2, and MM-HR-3 would reduce the
maximum cancer risks at the residential point of maximum impact. The results of the risk assessment
with mitigation are shown in Table 11.

The cancer and non-cancer results of the roadway HRA show that with mitigation the project
would not exceed the SDAPCD significance thresholds. Therefore, TAC emissions from the 805
freeway would not expose sensitive receptors to substantial pollutant concentrations with
mitigation.
2.5.5 Would the project create objectionable odors affecting a substantial
number of people?
The State of California Health and Safety Code, Division 26, Part 4, Chapter 3, Section 41700
and SDAPCD Rule 51, commonly referred to as public nuisance law, prohibits emissions from
any source whatsoever in such quantities of air contaminants or other material that cause injury,
detriment, nuisance, or annoyance to the public health or damage to property. Projects required
to obtain permits from SDAPCD are evaluated by SDAPCD staff for potential odor nuisance,
and conditions may be applied (or control equipment required) where necessary to prevent
occurrence of public nuisance.
Section 19.66.090, Odors, of the Chula Vista Municipal Code requires that no emission shall be
permitted of odorous gases or other odorous matter in such quantities as to be readily detectable
at the points of measurement specified in Chula Vista Municipal Code 19.66.060(A). Any
process that may involve the creation or emission of any odors shall be provided with an
adequate secondary safeguard system of control, so that control will be maintained if the primary
safeguard system should fail (City of Chula Vista 1969). SDAPCD Rule 51 (Public Nuisance)
also prohibits emission of any material that causes nuisance to a considerable number of persons
or endangers the comfort, health, or safety of any person. A project that proposes a use that
would produce objectionable odors would be deemed to have a significant odor impact if it
would affect a considerable number of off-site receptors. Odor issues are very subjective by the
nature of odors themselves and due to the fact that their measurements are difficult to quantify.
As a result, this guideline is qualitative and will focus on the existing and potential surrounding
uses and location of sensitive receptors.
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
48 December 2018
The occurrence and severity of potential odor impacts depends on numerous factors: the nature,
frequency, and intensity of the source; the wind speeds and direction; and the sensitivity of
receiving location each contribute to the intensity of the impact. Although offensive odors
seldom cause physical harm, they can be annoying, cause distress among the public, and
generate citizen complaints.
Odors would be potentially generated from vehicles and equipment exhaust emissions during
construction of the Project. Potential odors produced during construction would be attributable to
concentrations of unburned hydrocarbons from tailpipes of construction equipment, architectural
coatings, and asphalt pavement application. Such odors would disperse rapidly from the Project
site and generally occur at magnitudes that would not affect substantial numbers of people.
Therefore, impacts associated with odors during construction would be less than significant.
Land uses and industrial operations associated with odor complaints include agricultural uses,
wastewater treatment plants, food-processing plants, chemical plants, composting, refineries,
landfills, dairies, and fiberglass molding (SCAQMD 1993). The Project does not include any of
the land uses typically associated with odor complaints. Therefore, Project operations would
result in an odor impact that would be less than significant.
Mitigation Measures
No mitigation is required.
Level of Significance After Mitigation
The Project would have a less-than-significant impact prior to mitigation.

3 GREENHOUSE GAS EMISSIONS
3.1 Environmental Setting
3.1.1 Climate Change Overview
Climate change refers to any significant change in measures of climate, such as temperature,
precipitation, or wind patterns, lasting for an extended period of time (decades or longer). The
Earth’s temperature depends on the balance between energy entering and leaving the planet’s
system. Many factors, both natural and human, can cause changes in Earth’s energy balance,
including variations in the Sun’s energy reaching Earth, changes in the reflectivity of Earth’s
atmosphere and surface, and changes in the greenhouse effect, which affects the amount of heat
retained by Earth’s atmosphere (EPA 2017a).
The greenhouse effect is the trapping and build -up of heat in the atmosphere (troposphere) near
the Earth’s surface. The greenhouse effe ct traps heat in the troposphere through a threefold
process as follows: short-wave radiation emitted by the Sun is absorbed by the Earth; the Earth
emits a portion of this energy in the form of long -wave radiation; and greenhouse gasses
(GHGs) in the upper atmosphere absorb this long -wave radiation and emit it into space and
toward the Earth. The greenhouse effect is a natural process that contributes to regulating the
Earth’s temperature and creates a pleasant, livable environment on the Earth. Human acti vities
that emit additional GHGs to the atmosphere increase the amount of infrared radiation that gets
absorbed before escaping into space, thus enhancing the greenhouse effect and causing the
Earth’s surface temperature to rise.
The scientific record of the Earth’s climate shows that the climate system varies naturally over a
wide range of time scales and that, in general, climate changes prior to the Industrial Revolution
in the 1700s can be explained by natural causes, such as changes in solar energy, volcanic
eruptions, and natural changes in GHG concentrations. Recent climate changes, in particular the
warming observed over the past century, however, cannot be explained by natural causes alone.
Rather, it is extremely likely that human activities have been the dominant cause of that warming
since the mid-20th century and is the most significant driver of observed climate change (IPCC
2013, EPA 2017a). Human influence on the climate system is evident from the increasing GHG
concentrations in the atmosphere, positive radiative forcing, observed warming, and improved
understanding of the climate system (IPCC 2013). The atmospheric concentrations of GHGs
have increased to levels unprecedented in the last 800,000 years, primarily from fossil fuel
emissions and secondarily from emissions associated with land use changes (IPCC 2013).
Continued emissions of GHGs will cause further warming and changes in all components of the
climate system, which is discussed further in Section 3.3.2, Potential Effects of Climate Change.

3.1.2 Greenhouse Gases
A GHG is any gas that absorbs infrared radiation in the atmosphere; in other words, GHGs trap
heat in the atmosphere. GHGs include, but are not limited to, carbon dioxide (CO2), methane
(CH4), nitrous oxide (N2O), ozone (O3), water vapor, hydrofluorocarbons (HFCs),
hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6).4
Some GHGs, such as CO2, CH4, and N2O, occur naturally and are emitted to the atmosphere
through natural processes and human activities. Of these gases, CO2 and CH4 are emitted in the
greatest quantities from human activities. Manufactured GHGs, which have a much greater h eat-
absorption potential than CO2, include fluorinated gases, such as HFCs, HCFCs, PFCs, and SF6,
which are associated with certain industrial products and processes. A summary of the most
common GHGs and their sources is included in the following text.5 Also included is a discussion
of other climate-forcing substances.
Carbon Dioxide. CO2 is a naturally occurring gas and a by-product of human activities and is the
principal anthropogenic GHG that affects the Earth’s radiative balance. Natural sources of CO2
include respiration of bacteria, plants, animals, and fungus; evaporation from oceans; volcanic out-
gassing; and decomposition of dead organic matter. Human activities that generate CO2 are from the
combustion of fuels, such as coal, oil, natural gas, and wood, and changes in land use.
Methane. CH4 is produced through both natural and human activities. CH4 is a flammable gas
and is the main component of natural gas. Methane is produced through anaerobic (without
oxygen) decomposition of waste in landfills, flooded rice fields, animal digestion, decomposition
of animal wastes, production and distribution of natural gas and petroleum, coal production, and
incomplete fossil fuel combustion.
Nitrous Oxide. N2O is produced through natural and human activities, mainly through
agricultural activities and natural biological processes, although fuel burning and other processes
also create N2O. Sources of N2O include soil cultivation practices (microbial processes in soil
and water), especially the use of commercial and organic fertilizers, manure management,
industrial processes (such as in nitric acid production, nylon production, and fossil-fuel-fired
power plants), vehicle emissions, and using N2O as a propellant (such as in rockets, race cars,
and aerosol sprays).
4 California Health and Safety Code 38505 identifies seven GHGs that the California Air Resources Board
(CARB) is responsible for monitoring and regulating to reduce emissions: CO2, CH4, N2O, SF6, HFCs, PFCs,
and nitrogen trifluoride.
5 The descriptions of GHGs are summarized from the Intergovernmental Panel on Climate Change (IPCC)
Second Assessment Report (1995), IPCC Fourth Asse ssment Report (2007), CARB’s Glossary of Terms Used
in GHG Inventories (2015), and the U.S. Environmental Protection Agency’s (EPA’s) Glossary of Climate
Change Terms (2016f).

51 December 2018
Fluorinated Gases. Fluorinated gases (also referred to as F-gases) are synthetic powerful GHGs
emitted from many industrial processes. Fluorinated gases are commonly used as substitutes for
stratospheric O3-depleting substances (e.g., CFCs, HCFCs, and halons). The most prevalent
fluorinated gases include the following:
Hydrofluorocarbons: HFCs are compounds containing only hydrogen, fluorine, and
carbon atoms. HFCs are synthetic chemicals used as alternatives to O3-depleting
substances in serving many industrial, commercial, and personal needs. HFCs are emitted
as byproducts of industrial processes and are used in manufacturing.
Perfluorocarbons: PFCs are a group of human-made chemicals composed of carbon and
fluorine only. These chemicals were introduced as alternatives, with HFCs, to the O3-
depleting substances. The two main sources of PFCs are primary aluminum production
and semiconductor manufacturing. Since PFCs have stable molecular structures and do
not break down through the chemical processes in the lower atmosphere, these chemicals
have long lifetimes, ranging between 10,000 and 50,000 years.
Sulfur Hexafluoride: SF6 is a colorless gas soluble in alcohol and ether and slightly
soluble in water. SF6 is used for insulation in electric power transmission and distribution
equipment, semiconductor manufacturing, the magnesium industry, and as a tracer gas
for leak detection.
Nitrogen Trifluoride: NF3 is used in the manufacture of a variety of electronics,
including semiconductors, and flat panel displays.
Chlorofluorocarbons. CFCs are synthetic chemicals that have been used as cleaning solvents,
refrigerants, and aerosol propellants. CFCs are chemically unreactive in the lower atmosphere
(troposphere), and the production of CFCs was prohibited in 1987 due to the chemical
destruction of stratospheric O3.
Hydrochlorofluorocarbons. HCFCs are a large group of compounds with a structure very close to
that of CFCs—containing hydrogen, fluorine, chlorine, and carbon atoms—but including one or
more hydrogen atoms. Like HFCs, HCFCs are used in refrigerants and propellants. HCFCs were also
used in place of CFCs for some applications; however, their use in general is being phased out.
Black Carbon. Black carbon is a component of fine particulate matter (PM2.5), which has been
identified as a leading environmental risk factor for premature death. It is produced from the
incomplete combustion of fossil fuels and biomass burning, particularly from older diesel
engines and forest fires. Black carbon warms the atmosphere by absorbing solar radiation,
influences cloud formation, and darkens the surface of snow and ice, which accelerates heat
absorption and melting. Black carbon is a short-lived species that varies spatially, which makes it
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271

difficult to quantify the global warming potential (GWP). DPM emissions are a major source of
black carbon and are TACs that have been regulated and controlled in California for several
decades to protect public health. In relation to declining DPM from the CARB’s regulations
pertaining to diesel engines, diesel fuels, and burning activities, CARB estimates that annual
black carbon emissions in California have reduced by 70% between 1990 and 2010, with 95%
control expected by 2020 (CARB 2014a).
Water Vapor. The primary source of water vapor is evaporation from the ocean, with additional
vapor generated by sublimation (change from solid to gas) from ice and snow, evaporation from
other water bodies, and transpiration from plant leaves. Water vapor is the most important,
abundant, and variable GHG in the atmosphere and maintains a climate necessary for life.
Ozone. Tropospheric O3, which is created by photochemical reactions involving gases from both
natural sources and human activities, acts as a GHG. Stratospheric O3, which is created by the
interaction between solar ultraviolet radiation and molecular oxygen (O2), plays a decisive role in the
stratospheric radiative balance. Depletion of stratospheric O3, due to chemical reactions that may be
enhanced by climate change, results in an increased ground-level flux of ultraviolet-B radiation.
Aerosols. Aerosols are suspensions of particulate matter in a gas emitted into the air through
burning biomass (plant material) and fossil fuels. Aerosols can warm the atmosphere by
absorbing and emitting heat and can cool the atmosphere by reflecting light.
3.1.3 Global Warming Potential
Gases in the atmosphere can contribute to climate change both directly and indirectly. Direct
effects occur when the gas itself absorbs radiation. Indirect radiative forcing occurs when
chemical transformations of the substance produce other GHGs, when a gas influences the
atmospheric lifetimes of other gases, and/or when a gas affects atmospheric processes that alter
the radiative balance of the Earth (e.g., affect cloud formation or albedo) (EPA 2016). The
Intergovernmental Panel on Climate Change (IPCC) developed the GWP concept to compare the
ability of each GHG to trap heat in the atmosphere relative to another gas. The GWP of a GHG is
defined as the ratio of the time-integrated radiative forcing from the instantaneous release of 1
kilogram of a trace substance relative to that of 1 kilogram of a reference gas (IPCC 2014). The
reference gas used is CO2; therefore, GWP-weighted emissions are measured in metric tons
(MT) of carbon dioxide equivalent (CO2E).
The current version of California Emissions Estimator Model (CalEEMod) (version 2016.3.2)
assumes that the GWP for CH4 is 25 (so emissions of 1 MT of CH4 are equivalent to emissions of 25
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
53 December 2018
MT of CO2), and the GWP for N2O is 298, based on the IPCC Fourth Assessment Report (IPCC
2007). The GWP values identified in CalEEMod were applied to the Bonita Glen Project (Project).
3.2 Regulatory Setting
3.2.1 Federal Regulations
Massachusetts v. EPA. In Massachusetts v. EPA (April 2007), the U.S. Supreme Court directed
the U.S. Environmental Protection Agency (EPA) administrator to determine whether GHG
emissions from new motor vehicles cause or contribute to air pollution that may reasonably be
anticipated to endanger public health or welfare, or whether the science is too uncertain to make
a reasoned decision. In December 2009, the administrator signed a final rule with the following
two distinct findings regarding GHGs under Section 202(a) of the federal Clean Air Act (CAA):
The administrator found that elevated concentrations of GHGs—CO2, CH4, N2O, HFCs,
PFCs, and SF6—in the atmosphere threaten the public health and welfare of current and
future generations. This is the “endangerment finding.”
The administrator further found the combined emissions of GHGs —CO2, CH4, N2O,
and HFCs—from new motor vehicles and new motor vehicle engines contribute to the
GHG air pollution that endangers public health and welfare. This is the “cause or
contribute finding.”
These two findings were necessary to establish the foundation for regulation of GHGs from new
motor vehicles as air pollutants under the CAA.
Energy Independence and Security Act. The Energy Independence and Security Act of 2007
(December 2007), among other key measures, would do the following, which would aid in the
reduction of national GHG emissions (EPA 2007):
Increase the supply of alternative fuel sources by setting a mandatory Renewable Fuel
Standard requiring fuel producers to use at least 36 billion gallons of biofuel in 2022.
Set a target of 35 miles per gallon for the combined fleet of cars and light trucks by model
year 2020 and direct National Highway Traffic Safety Administration (NHTSA) to establish
a fuel economy program for medium- and heavy-duty trucks and create a separate fuel
economy standard for work trucks.
Prescribe or revise standards affecting regional efficiency for heating and cooling
products and procedures for new or amended standards, energy conservation, energy
efficiency labeling for consumer electronic products, residential boiler efficiency, electric
motor efficiency, and home appliances.

Federal Vehicle Standards. In response to the U.S. Supreme Court ruling discussed above, the
Bush Administration issued Executive Order (EO) 13432 in 2007 directing the EPA, the
Department of Transportation, and the Department of Energy to establish regulations that reduce
GHG emissions from motor vehicles, non-road vehicles, and non-road engines by 2008. In 2009,
the NHTSA issued a final rule regulating fuel efficiency and GHG emissions from cars and light-
duty trucks for model year 2011, and in 2010, the EPA and NHTSA issued a final rule regulating
cars and light-duty trucks for model years 2012–2016 (75 FR 25324–25728).
In 2010, President Obama issued a memorandum directing the Department of Transportation,
Department of Energy, EPA, and NHTSA to establish additional standards regarding fuel
efficiency and GHG reduction, clean fuels, and advanced vehicle infrastructure. In response to
this directive, the EPA and NHTSA proposed stringent, coordinated federal GHG and fuel
economy standards for model years 2017–2025 light-duty vehicles. The proposed standards
projected to achieve 163 grams/mile of CO2 in model year 2025, on an average industry fleet-
wide basis, which is equivalent to 54.5 miles per gallon if this level were achieved solely through
fuel efficiency. The final rule was adopted in 2012 for model years 2017–2021 (77 FR 62624–
63200), and NHTSA intends to set standards for model years 2022–2025 in a future rulemaking.
In addition to the regulations applicable to cars and light-duty trucks described above, in 2011,
the EPA and NHTSA announced fuel economy and GHG standards for medium- and heavy-duty
trucks for model years 2014–2018. The standards for CO2 emissions and fuel consumption are
tailored to three main vehicle categories: combination tractors, heavy-duty pickup trucks and
vans, and vocational vehicles. According to the EPA, this regulatory program will reduce GHG
emissions and fuel consumption for the affected vehicles by 6%–23% over the 2010 baselines
(76 FR 57106–57513).
In August 2016, the EPA and NHTSA announced the adoption of the phase two program related
to the fuel economy and GHG standards for medium- and heavy-duty trucks. The phase two
program will apply to vehicles with model year 2018 through 2027 for certain trailers and model
years 2021 through 2027 for semi-trucks, large pickup trucks, vans, and all types of sizes of
buses and work trucks. The final standards are expected to lower CO2 emissions by
approximately 1.1 billion MT and reduce oil consumption by up to 2 billion barrels over the
lifetime of the vehicles sold under the program (EPA and NHTSA 2016).
Clean Power Plan and New Source Performance Standards for Electric Generating Units.
In October 2015, EPA published a final rule (effective December 2015) establishing the Carbon
Pollution Emission Guidelines for Existing Stationary Sources: Electric Utility Generating Units
(80 FR 64510–64660), also known as the Clean Power Plan. These guidelines prescribe how
states must develop plans to reduce GHG emissions from existing fossil-fuel-fired electric

generating units. The guidelines establish CO2 emission performance rates representing the best
system of emission reduction for two subcategories of existing fossil-fuel-fired electric
generating units: (1) fossil-fuel-fired electric utility steam-generating units and (2) stationary
combustion turbines. Concurrently, EPA published a final rule in October 2015 establishing
Standards of Performance for Greenhouse Gas Emissions from New, Modified, and
Reconstructed Stationary Sources: Electric Utility Generating Units (80 FR 64661–65120). The
rule prescribes CO2 emission standards for newly constructed, modified, and reconstructed
affected fossil-fuel-fired electric utility generating units. Implementation of the Clean Power
Plan has been stayed by the U.S. Supreme Court pending resolution of several lawsuits;
additionally, President Trump has called upon the EPA to review the Clean Power Plan.
3.2.2 State Regulations
The statewide GHG emissions regulatory framework is summarized below by category: state
climate change targets, building energy, renewable energy and energy procurement, mobile
sources, solid waste, water, and other state regulations and goals. The following text describes
EOs, legislation, regulations, and other plans and policies that would directly or indirectly reduce
GHG emissions and/or address climate change issues.
State Climate Change Targets
EO S-3-05. EO S-3-05 (June 2005) established the following statewide goals: GHG emissions
should be reduced to 2000 levels by 2010; GHG emissions should be reduced to 1990 levels by
2020; and GHG emissions should be reduced to 80% below 1990 levels by 2050.
Assembly Bill 32 and CARB’s Climate Change Scoping Plan. In furtherance of the goals
established in EO S-3-05, the Legislature enacted Assembly Bill (AB) 32, the California Global
Warming Solutions Act of 2006. AB 32 requires California to reduce its GHG emissions to 1990
levels by 2020.
Under AB 32, CARB is responsible for and is recognized as having the expertise to carry out and
develop the programs and requirements necessary to achieve the GHG emissions reduction
mandate of AB 32. Under AB 32, CARB must adopt regulations requiring the reporting and
verification of statewide GHG emissions from specified sources. This program is used to monitor
and enforce compliance with established standards. CARB also is required to adopt rules and
regulations to achieve the maximum technologically feasible and cost-effective GHG emission
reductions. AB 32 relatedly authorized CARB to adopt market-based compliance mechanisms to
meet the specified requirements. Finally, CARB is ultimately responsible for monitoring
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
56 December 2018
compliance and enforcing any rule, regulation, order, emission limitation, emission reduction
measure, or market-based compliance mechanism adopted.
In 2007, CARB approved a limit on the statewide GHG emissions level for year 2020 consistent
with the determined 1990 baseline (427 MMT CO2E). CARB’s adoption of this limit is in
accordance with Health and Safety Code Section 38550.
Further, in 2008, CARB adopted the Climate Change Scoping Plan: A Framework for Change
(Scoping Plan) in accordance with Health and Safety Code Section 38561. The Scoping Plan
establishes an overall framework for the measures that will be adopted to reduce California’s
GHG emissions for various emission sources/sectors to 1990 levels by 2020. The Scoping Plan
evaluates opportunities for sector-specific reductions, integrates all CARB and Climate Action
Team early actions and additional GHG reduction features by both entities, identifies additional
measures to be pursued as regulations, and outlines the role of a cap-and-trade program. The key
elements of the Scoping Plan include the following (CARB 2008):
1. Expanding and strengthening existing energy efficiency programs, as well as building
and appliance standards.
2. Achieving a statewide renewable energy mix of 33%.
3. Developing a California cap-and-trade program that links with other Western Climate
Initiative partner programs to create a regional market system and caps sources
contributing 85% of California’s GHG emissions.
4. Establishing targets for transportation-related GHG emissions for regions throughout
California, and pursuing policies and incentives to achieve those targets.
5. Adopting and implementing measures pursuant to existing state laws and policies,
including California’s clean car standards, goods movement measures, and the Low
Carbon Fuel Standard.
6. Creating targeted fees, including a public goods charge on water use, fees on high GWP
gases, and a fee to fund the administrative costs of the State of California’s long-term
commitment to AB 32 implementation.
In the Scoping Plan, CARB determined that achieving the 1990 emissions level in 2020 would
require a reduction in GHG emissions of approximately 28.5% from the otherwise projected
2020 emissions level; i.e., those emissions that would occur in 2020, absent GHG-reducing laws
and regulations (referred to as “Business-As-Usual”). For purposes of calculating this percent
reduction, CARB assumed that all new electricity generation would be supplied by natural gas
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
57 December 2018
plants; no further regulatory action would impact vehicle fuel efficiency; and building energy
efficiency codes would be held at 2005 standards.
In the 2011 Final Supplement to the Scoping Plan’s Functional Equivalent Document, CARB
revised its estimates of the projected 2020 emissions level in light of the economic recession and
the availability of updated information about GHG reduction regulations. Based on the new
economic data, CARB determined that achieving the 1990 emissions level by 2020 would require
a reduction in GHG emissions of 21.7% (down from 28.5%) from the Business-As-Usual
conditions. When the 2020 emissions level projection also was updated to account for newly
implemented regulatory measures, including Pavley I (model years 2009–2016) and the
Renewables Portfolio Standard (RPS; CPUC 2015; 12% to 20%), CARB determined that
achieving the 1990 emissions level in 2020 would require a reduction in GHG emissions of 16%
(down from 28.5%) from the Business-As-Usual conditions.
More recently, in 2014, CARB adopted the First Update to the Climate Change Scoping Plan:
Building on the Framework (First Update). The stated purpose of the First Update is to
“highlight California’s success to date in reducing its GHG emissions and lay the foundation for
establishing a broad framework for continued emission reductions beyond 2020, on the path to
80% below 1990 levels by 2050” (CARB 2014b). The First Update found that California is on
track to meet the 2020 emissions reduction mandate established by AB 32 and noted that
California could reduce emissions further by 2030 to levels squarely in line with those needed to
stay on track to reduce emissions to 80% below 1990 levels by 2050 if the state realizes the
expected benefits of existing policy goals.
In conjunction with the First Update, CARB identified “six key focus areas comprising major
components of the state’s economy to evaluate and describe the larger transformative actions that
will be needed to meet the state’s more expansive emission reduction needs by 2050” (CARB
2014b). Those six areas are: (1) energy; (2) transportation (vehicles/equipment, sustainable
communities, housing, fuels, and infrastructure); (3) agriculture; (4) water; (5) waste
management; and (6) natural and working lands. The First Update identifies key recommended
actions for each sector that will facilitate achievement of EO S-3-05’s 2050 reduction goal.
CARB’s research efforts presented in the First Update indicate that it has a “strong sense of
the mix of technologies needed to reduce emissions through 2050” (CARB 2014b). Those
technologies include energy demand reduction through efficiency and activity changes;
large-scale electrification of on -road vehicles, buildings, and industrial machinery;
decarbonizing electricity and fuel supplies; and the rapid market pene tration of efficient and
clean energy technologies.

As part of the First Update, CARB recalculated the state’s 1990 emissions level using more recent
GWPs identified by the IPCC. Using the recalculated 1990 emissions level (431 MMT CO2E) and the
revised 2020 emissions level projection identified in the 2011 Final Supplement, CARB determined
that achieving the 1990 emissions level by 2020 would require a reduction in GHG emissions of
approximately 15% (instead of 28.5% or 16%) from the Business-As-Usual conditions.
On January 20, 2017, CARB released The 2017 Climate Change Scoping Plan Update (Second
Update) for public review and comment (CARB 2017b). This update presents CARB’s strategy
for achieving the state’s 2030 GHG target as established in SB 32 (discussed below), including
continuing the Cap-and-Trade Program through 2030, and includes a new approach to reduce
GHGs from refineries by 20%. The Second Update incorporates approaches to cutting short-
lived climate pollutants (SLCPs) under the Short-Lived Climate Pollutant Reduction Strategy (a
planning document that was adopted by CARB in March 2017) and acknowledges the need for
reducing emissions in agriculture and highlights the work underway to ensure that California’s
natural and working lands increasingly sequester carbon. During development of the Second
Update, CARB held a number of public workshops in the Natural and Working Lands,
Agriculture, Energy, and Transportation sectors to inform development of the 2030 Scoping Plan
Update (CARB 2016). When discussing project-level GHG emissions reduction actions and
thresholds, the Second Update states “achieving no net increase in GHG emissions is the correct
overall objective, but it may not be appropriate or feasible for every development project. An
inability to mitigate a project’s GHG emissions to zero does not necessarily imply a substantial
contribution to the cumulatively significant environmental impact of climate change under
CEQA” (CARB 2017b). The Final Proposed Scoping Plan Update was adopted by CARB’s
Governing Board on December 14, 2017.
EO B-30-15. EO B-30-15 (April 2015) identified an interim GHG reduction target in support of
targets previously identified under S-3-05 and AB 32. EO B-30-15 set an interim target goal of
reducing statewide GHG emissions to 40% below 1990 levels by 2030 to keep California on its
trajectory toward meeting or exceeding the long-term goal of reducing statewide GHG emissions
to 80% below 1990 levels by 2050 as set forth in S-3-05. To facilitate achievement of this goal,
EO B-30-15 calls for an update to CARB’s Scoping Plan to express the 2030 target in terms of
MMT CO2E. The EO also calls for state agencies to continue to develop and implement GHG
emission reduction programs in support of the reduction targets. EO B-30-15 does not require
local agencies to take any action to meet the new interim GHG reduction target.
SB 32 and AB 197. SB 32 and AB 197 (enacted in 2016) are companion bills that set a new
statewide GHG reduction targets, make changes to CARB’s membership and increase legislative
oversight of CARB’s climate change–based activities, and expand dissemination of GHG and
other air quality-related emissions data to enhance transparency and accountability. More
Air Quality and Greenhouse Gas Emissions Analysis

59 December 2018
specifically, SB 32 codified the 2030 emissions reduction goal of EO B-30-15 by requiring
CARB to ensure that statewide GHG emissions are reduced to 40% below 1990 levels by 2030.
AB 197 established the Joint Legislative Committee on Climate Change Policies, consisting of at
least three members of the Senate and three members of the Assembly, in order to provide
ongoing oversight over implementation of the state’s climate policies. AB 197 also added two
members of the Legislature to CARB as nonvoting members; requires CARB to make available
and update (at least annually via its website) emissions data for GHGs, criteria air pollutants, and
TACs from reporting facilities; and, requires CARB to identify specific information for GHG
emissions reduction measures when updating the Scoping Plan.
SB 605 and SB 1383. SB 605 (2014) requires CARB to complete a comprehensive strategy to
reduce emissions of SLCPs in the state, and SB 1383 (2016) requires CARB to approve and
implement that strategy by January 1, 2018. SB 1383 also establishes specific targets for the
reduction of SLCPs (40% below 2013 levels by 2030 for CH4 and HFCs and 50% below 2013
levels by 2030 for anthropogenic black carbon) and provides direction for reductions from dairy
and livestock operations and landfills. Accordingly, and as mentioned above, CARB adopted its
Short-Lived Climate Pollutant Reduction Strategy (SLCP Reduction Strategy) in March 2017.
The SLCP Reduction Strategy establishes a framework for the statewide reduction of emissions
of black carbon, CH4, and fluorinated gases.
Building Energy
Title 24, Part 6. Title 24 of the California Code of Regulations was established in 1978 and
serves to enhance and regulate California’s building standards. While not initially promulgated
to reduce GHG emissions, Part 6 of Title 24 specifically establishes Building Energy Efficiency
Standards that are designed to ensure new and existing buildings in California achieve energy
efficiency and preserve outdoor and indoor environmental quality. These energy efficiency
standards are reviewed every few years by the Building Standards Commission and the
California Energy Commission (CEC) (and revised if necessary) (California Public Resources
Code, Section 25402(b)(1)). The regulations receive input from members of industry, as well as
the public, with the goal of “reducing of wasteful, uneconomic, inefficient, or unnecessary
consumption of energy” (California Public Resources Code, Section 25402). These regulations
are carefully scrutinized and analyzed for technological and economic feasibility (California
Public Resources Code, Section 25402(d)) and cost effectiveness (California Public Resources
Code, Sections 25402(b)(2) and (b)(3)). These standards are updated to consider and incorporate
new energy-efficient technologies and construction methods. As a result, these standards save
energy, increase electricity supply reliability, increase indoor comfort, avoid the need to
construct new power plants, and help preserve the environment.

The 2016 Title 24 standards are the currently applicable building energy efficiency standards and
became effective on January 1, 2017. In general, single-family homes built to the 2016 standards are
anticipated to use about 28% less energy for lighting, heating, cooling, ventilation, and water heating
than those built to the 2013 standards, and nonresidential buildings built to the 2016 standards will
use an estimated 5% less energy than those built to the 2013 standards (CEC 2015).
Title 24, Part 11. In addition to the CEC’s efforts, in 2008, the California Building Standards
Commission adopted the nation’s first green building standards. The California Green Building
Standards Code (CALGreen 2016) is commonly referred to as CALGreen and establishes minimum
mandatory standards as well as voluntary standards pertaining to the planning and design of
sustainable site development, energy efficiency (in excess of the California Energy Code
requirements), water conservation, material conservation, and interior air quality. The CALGreen
standards took effect in January 2011 and instituted mandatory minimum environmental
performance standards for all ground-up, new construction of commercial, low-rise residential and
state-owned buildings and schools and hospitals. The CALGreen 2016 standards became effective on
January 1, 2017. The mandatory standards require the following (CALGreen 2016):
Mandatory reduction in indoor water use through compliance with specified flow rates
for plumbing fixtures and fittings.
Mandatory reduction in outdoor water use through compliance with a local water
efficient landscaping ordinance or the California Department of Water Resources’ Model
Water Efficient Landscape Ordinance.
65% of construction and demolition waste must be diverted from landfills.
Mandatory inspections of energy systems to ensure optimal working efficiency.
Inclusion of electric vehicle charging stations or designated spaces capable of supporting
future charging stations.
Low-pollutant emitting exterior and interior finish materials, such as paints, carpets, vinyl
flooring, and particle boards.
The CALGreen standards also include voluntary efficiency measures that are provided at two
separate tiers and implemented at the discretion of local agencies and applicants. CALGreen’s
Tier 1 standards call for a 15% improvement in energy requirements, stricter water conservation,
65% diversion of construction and demolition waste, 10% recycled content in building materials,
20% permeable paving, 20% cement reduction, and cool/solar-reflective roofs. CALGreen’s more
rigorous Tier 2 standards call for a 30% improvement in energy requirements, stricter water
conservation, 75% diversion of construction and demolition waste, 15% recycled content in
building materials, 30% permeable paving, 25% cement reduction, and cool/solar-reflective roofs.

The California Public Utilities Commission (CPUC), CEC, and CARB also have a shared,
established goal of achieving zero net energy (ZNE) for new construction in California. The key
policy timelines include: (1) all new residential construction in California will be ZNE by 2020,
and (2) all new commercial construction in California will be ZNE by 2030 (CPUC 2013).6 As
most recently defined by the CEC in its 2015 Integrated Energy Policy Report, a ZNE code
building is “one where the value of the energy produced by on-site renewable energy resources is
equal to the value of the energy consumed annually by the building” using the CEC’s Time
Dependent Valuation metric (CEC 2015b).
Title 20. Title 20 of the California Code of Regulations requires manufacturers of appliances to
meet state and federal standards for energy and water efficiency. Performance of appliances must
be certified through the CEC to demonstrate compliance with standards. New appliances
regulated under Title 20 include refrigerators, refrigerator-freezers, and freezers; room air
conditioners and room air-conditioning heat pumps; central air conditioners; spot air
conditioners; vented gas space heaters; gas pool heaters; plumbing fittings and plumbing
fixtures; fluorescent lamp ballasts; lamps; emergency lighting; traffic signal modules;
dishwaters; clothes washers and dryers; cooking products; electric motors; low voltage dry-type
distribution transformers; power supplies; televisions and consumer audio and video equipment;
and battery charger systems. Title 20 presents protocols for testing for each type of appliance
covered under the regulations, and appliances must meet the standards for energy performance,
energy design, water performance, and water design. Title 20 contains three types of standards
for appliances: federal and state standards for federally regulated appliances, state standards for
federally regulated appliances, and state standards for non-federally regulated appliances.
SB 1. SB 1 (2006) established a $3 billion rebate program to support the goal of the state to
install rooftop solar energy systems with a generation capacity of 3,000 megawatts through
2016. SB 1 added sections to the Public Resources Code, including Chapter 8.8 (California
Solar Initiative), that require building projects applying for ratepayer -funded incentives for
photovoltaic systems to meet minimum energy ef ficiency levels and performance
requirements. Section 25780 established that it is a goal of the state to establish a self -
sufficient solar industry in which solar energy systems are a viable mainstream option for both
homes and businesses within 10 years of adoption and to place solar energy systems on 50% of
new homes within 13 years of adoption. SB 1, also termed “GoSolarCalifornia,” was
previously titled “Million Solar Roofs.”
6 It is expected that achievement of the ZNE goal will occur via revisions to t he Title 24 standards.

AB 1470. This bill established the Solar Water Heating and Efficiency Act of 2007. The bill
makes findings and declarations of the Legislature relating to the promotion of solar water
heating systems and other technologies that reduce natural gas demand. The bill defines several
terms for purposes of the act. The bill requires the commission to evaluate the data available
from a specified pilot program and, if it makes a specified determination, to design and
implement a program of incentives for the installation of 200,000 solar water heating systems in
homes and businesses throughout the state by 2017.
AB 1109. Enacted in 2007, AB 1109 required the CEC to adopt minimum energy efficiency
standards for general purpose lighting, to reduce electricity consumption 50% for indoor
residential lighting and 25% for indoor commercial lighting.
Renewable Energy and Energy Procurement
SB 1078. SB 1078 (2002) established the RPS program, which requires an annual increase in
renewable generation by the utilities equivalent to at least 1% of sales, with an aggregate goal of
20% by 2017. This goal was subsequently accelerated, requiring utilities to obtain 20% of their
power from renewable sources by 2010.
SB 1368. SB 1368 (2006) requires the CEC to develop and adopt regulations for GHG emission
performance standards for the long-term procurement of electricity by local publicly owned
utilities. These standards must be consistent with the standards adopted by the CPUC. This effort
will help protect energy customers from financial risks associated with investments in carbon -
intensive generation by allowing new capital investments in power plants for which GHG
emissions are as low as or lower than new combined-cycle natural gas plants by requiring
imported electricity to meet GHG performance standards in California and by requiring that the
standards be developed and adopted in a public process.
SB X1 2. SB X1 2 (2011) expanded the RPS by establishing that 20% of the total electricity sold
to retail customers in California per year by December 31, 2013, and 33% by December 31,
2020, and in subsequent years be secured from qualifying renewable energy sources . Under the
bill, a renewable electrical generation facility is one that uses biomass, solar thermal,
photovoltaic, wind, geothermal, fuel cells using renewable fuels, small hydroelectric generation
of 30 megawatts or less, digester gas, municipal solid waste conversion, landfill gas, ocean wave,
ocean thermal, or tidal current and that meets other specified requirements with respect to its
location. In addition to the retail sellers previously covered by the RPS, SB X1 2 added local,
publicly owned electric utilities to the RPS.

SB 350. SB 350 (2015) further expanded the RPS by establishing that 50% of the total electricity
sold to retail customers in California per year by December 31, 2030, be secured from qualifying
renewable energy sources. In addition, SB 350 includes the goal to double the energy efficiency
savings in electricity and natural gas final end uses (such as heating, cooling, lighting, or class of
energy uses on which an energy-efficiency program is focused) of retail customers through energy
conservation and efficiency. The bill also requires the CPUC, in consultation with the CEC, to
establish efficiency targets for electrical and gas corporations consistent with this goal.
Mobile Sources
AB 1493. In a response to the transportation sector accounting for more than half of California’s
CO2 emissions, AB 1493 was enacted in July 2002. AB 1493 required CARB to set GHG
emission standards for passenger vehicles, light-duty trucks, and other vehicles determined by
the state board to be vehicles that are primarily used for noncommercial personal transportation
in the state. The bill required that CARB set GHG emission standards for motor vehicles
manufactured in 2009 and all subsequent model years. CARB adopted the standards in
September 2004. When fully phased in, the near-term (2009–2012) standards will result in a
reduction of about 22% in GHG emissions compared to the emissions from the 2002 fleet, while
the mid-term (2013–2016) standards will result in a reduction of about 30%.
EO S-1-07. Issued on January 18, 2007, EO S-1-07 sets a declining Low Carbon Fuel Standard
for GHG emissions measured in CO2E grams per unit of fuel energy sold in California. The
target of the Low Carbon Fuel Standard is to reduce the carbon intensity of California passenger
vehicle fuels by at least 10% by 2020. The carbon intensity measures the amount of GHG
emissions in the lifecycle of a fuel, including extraction/feedstock production, processing,
transportation, and final consumption, per unit of energy delivered. CARB adopted the
implementing regulation in April 2009. The regulation is expected to increase the production of
biofuels, including those from alternative sources, such as algae, wood, and agricultural waste.
SB 375. SB 375 (2008) addresses GHG emissions associated with the transportation sector
through regional transportation and sustainability plans. SB 375 required CARB to adopt
regional GHG reduction targets for the automobile and light-truck sector for 2020 and 2035.
Regional metropolitan planning organizations are then responsible for preparing a Sustainable
Communities Strategy (SCS) within their Regional Transportation Plan (RTP). The goal of the
SCS is to establish a forecasted development pattern for the region that, after considering
transportation measures and policies, will achieve, if feasible, the GHG reduction targets. If an
SCS is unable to achieve the GHG reduction target, a metropolitan planning organization must
prepare an Alternative Planning Strategy demonstrating how the GHG reduction target would be
achieved through alternative development patterns, infrastructure, or additional transportation
measures or policies.
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
64 December 2018
Pursuant to Government Code Section 65080(b)(2)(K), an SCS does not: (1) regulate the use of
land; (2) supersede the land use authority of cities and counties; or (3) require that a city’s or
county’s land use policies and regulations, including those in a general plan, be consistent with
it. Nonetheless, SB 375 makes regional and local planning agencies responsible for developing
those strategies as part of the federally required metropolitan transportation planning process and
the state-mandated housing element process.
In 2010, CARB adopted the SB 375 targets for the regional metropolitan planning organizations.
The targets for the San Diego Association of Governments (SANDAG) are a 7% reduction in
emissions per capita by 2020 and a 13% reduction by 2035.
SANDAG completed and adopted its 2050 Regional Transportation Plan/Sustainable
Communities Strategy (RTP/SCS) in October 2011 (SANDAG 2011). In November 2011,
CARB, by resolution, accepted SANDAG’s GHG emissions quantification analysis and
determination that, if implemented, the SCS would achieve CARB’s 2020 and 2035 GHG
emissions reduction targets for the region.
After SANDAG’s 2050 RTP/SCS was adopted, a lawsuit was filed by the Cleveland National
Forest Foundation and others. The matter is pending before the California Supreme Court (Case
No. S223603) for determination of whether an environmental impact report for an RTP must
include an analysis of the plan’s consistency with the GHG reduction goals reflected in EO S-3-
05 to comply with the California Environmental Quality Act (CEQA).
Although the environmental impact report for SANDAG’s 2050 RTP/SCS is pending before the
California Supreme Court, in 2015, SANDAG adopted the next iteration of its RTP/SCS in
accordance with statutorily mandated timelines, and no subsequent litigation challenge was filed.
More specifically, in October 2015, SANDAG adopted San Diego Forward: The Regional Plan.
Like the 2050 RTP/SCS, this planning document meets CARB’s 2020 and 2035 reduction targets
for the region (SANDAG 2015). In December 2015, CARB, by resolution, accepted SANDAG’s
GHG emissions quantification analysis and determination that, if implemented, the SCS would
achieve CARB’s 2020 and 2035 GHG emissions reduction targets for the region.
Advanced Clean Cars Program . In January 2012, CARB approved the Advanced Clean Cars
program, a new emissions-control program for model years 2015 through 2025. The program
combines the control of smog - and soot-causing pollutants and GHG emissions into a single
coordinated package. The package includes elements to reduce smog -forming pollution, reduce
GHG emissions, promote clean cars, and provide the fuels for clean cars (CARB 2011). To
improve air quality, CARB has implemented new emission s standards to reduce smog-forming
emissions beginning with 2015 model year vehicles. It is estimated that , in 2025, cars will emit
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
65 December 2018
75% less smog-forming pollution than the average new car sold before 2012. To reduce GHG
emissions, CARB, in conjunction with the EPA and the NHTSA, has adopted new GHG
standards for model year 2017 to 2025 vehicles; the new standards are estim ated to reduce
GHG emissions by 34% in 2025. The Zero -Emissions Vehicle (ZEV) program will act as the
focused technology of the Advanced Clean Cars program by requiring manufacturers to
produce increasing numbers of ZEVs and plug -in hybrid electric vehicle s in the 2018 to 2025
model years. The Clean Fuels Outlet regulation will ensure that fuels such as electricity and
hydrogen are available to meet the fueling needs of the new advanced technology vehicles as
they come to the market.
EO B-16-12. EO B-16-12 (2012) directs state entities under the governor’s direction and control
to support and facilitate development and distribution ZEVs. This EO also sets a long-term target
of reaching 1.5 million ZEVs on California’s roadways by 2025. On a statewide basis, EO B-16-
12 also establishes a GHG emissions reduction target from the transportation sector equaling
80% less than 1990 levels by 2050. In furtherance of this EO, the Governor convened an
Interagency Working Group on ZEVs that has published multiple reports regarding the progress
made on the penetration of ZEVs in the statewide vehicle fleet.
AB 1236. AB 1236 (2015) as enacted in California’s Planning and Zoning Law, requires local
land use jurisdictions to approve applications for the installation of electric vehicle charging
stations, as defined, through the issuance of specified permits, unless there is substantial
evidence in the record that the proposed installation would have a specific, adverse impact on
public health or safety and there is no feasible method to satisfactorily mitigate or avoid the
specific, adverse impact. The bill provides for appeal of that decision to the planning
commission, as specified. The bill requires local land use jurisdictions with a population of
200,000 or more residents to adopt an ordinance by September 30, 2016, that creates an
expedited and streamlined permitting process for electric vehicle charging stations, as specified.
Prior to this statutory deadline, in August 2016, the County Board of Supervisors adopted
Ordinance No. 10437 (N.S.) adding a section to its County Code related to the expedited
processing of electric vehicle charging stations permits consistent with AB 1236.
SB 350. In 2015, SB 350—the Clean Energy and Pollution Reduction Act—was enacted into
law. As one of its elements, SB 350 establishes a statewide policy for widespread electrification
of the transportation sector, recognizing that such electrification is required for achievement of
the state’s 2030 and 2050 reduction targets (see Public Utilities Code Section 740.12).

Solid Waste
AB 939 and AB 341. In 1989, AB 939, known as the Integrated Waste Management Act (Public
Resources Code Sections 40000 et seq.), was passed because of the increase in waste stream and
the decrease in landfill capacity. The statute established the California Integrated Waste
Management Board, which oversees a disposal reporting system. AB 939 mandated a reduction
of waste being disposed where jurisdictions were required to meet diversion goals of all solid
waste through source reduction, recycling, and composting activities of 25% by 1995 and 50%
by the year 2000.
AB 341 (2011) amended the California Integrated Waste Management Act of 1989 to include a
provision declaring that it is the policy goal of the state that not less than 75% of solid waste
generated be source-reduced, recycled, or composted by the year 2020 and annually thereafter. In
addition, AB 341 required the California Department of Resources Recycling and Recovery
(CalRecycle) to develop strategies to achieve the state’s policy goal. CalRecycle has conducted
multiple workshops and published documents that identify priority strategies that CalRecycle
believes would assist the state in reaching the 75% goal by 2020.
Water
EO B-29-15. In response to the ongoing drought in California, EO B-29-15 (April 2015) set a
goal of achieving a statewide reduction in potable urban water usage of 25% relative to water use
in 2013. The term of the EO extended through February 28, 2016, although many of the
directives have since become permanent water-efficiency standards and requirements. The EO
includes specific directives that set strict limits on water usage in the state. In response to EO B-
29-15, the California Department of Water Resources has modified and adopted a revised
version of the Model Water Efficient Landscape Ordinance that, among other changes,
significantly increases the requirements for landscape water use efficiency and broadens its
applicability to include new development projects with smaller landscape areas.
Other State Regulations and Goals
SB 97. SB 97 (Dutton) (August 2007) directed the Governor’s Office of Planning and Research
to develop guidelines under CEQA for the mitigation of GHG emissions. In 2008, the Office of
Planning and Research issued a technical advisory as interim guidance regarding the analysis of
GHG emissions in CEQA documents. The advisory indicated that the lead agency should
identify and estimate a project’s GHG emissions, including those associated with vehicular
traffic, energy consumption, water usage, and construction activities (OPR 2008). The advisory
further recommended that the lead agency determine significance of the impacts and impose all
Air Quality and Greenhouse Gas Emissions Analysis

10271
67 December 2018
mitigation measures necessary to reduce GHG emissions to a level that is less than significant.
The California Natural Resources Agency adopted the CEQA Guidelines amendments in
December 2009, which became effective in March 2010.
Under the amended CEQA Guidelines, a lead agency has the discretion to determine whether to
use a quantitative or qualitative analysis or apply performance standards to determine the
significance of GHG emissions resulting from a particular project (14 CCR 15064.4(a)). The
Guidelines require a lead agency to consider the extent to which the project complies with
regulations or requirements adopted to implement a statewide, regional, or local plan for the
reduction or mitigation of GHG emissions (14 CCR 15064.4(b)). The Guidelines also allow a
lead agency to consider feasible means of mitigating the significant effects of GHG emissions,
including reductions in emissions through the implementation of project features or off-site
measures. The adopted amendments do not establish a GHG emission threshold, instead allowing
a lead agency to develop, adopt, and apply its own thresholds of significance or those developed
by other agencies or experts. The California Natural Resources Agency also acknowledges that a
lead agency may consider compliance with regulations or requirements implementing AB 32 in
determining the significance of a project’s GHG emissions (CNRA 2009a).
With respect to GHG emissions, the CEQA Guidelines state in Section 15064.4(a) that lead
agencies should “make a good faith effort, to the extent possible on scientific and factual data, to
describe, calculate or estimate” GHG emissions. The CEQA Guidelines note that an agency may
identify emissions by either selecting a “model or methodology” to quantify the emissions or by
relying on “qualitative analysis or other performance based standards” (14 CCR 15064.4(a)).
Section 15064.4(b) states that the lead agency should consider the following when assessing the
significance of impacts from GHG emissions on the environment: (1) the extent a project may
increase or reduce GHG emissions as compared to the existing environmental setting; (2)
whether the project emissions exceed a threshold of significance that the lead agency determines
applies to the project; and (3) the extent to which the project complies with regulations or
requirements adopted to implement a statewide, regional, or local plan for the reduction or
mitigation of GHG emissions (14 CCR 15064.4(b)).
EO S-13-08. EO S-13-08 (November 2008) is intended to hasten California’s response to the
impacts of global climate change, particularly s ea-level rise. Therefore, the EO directs state
agencies to take specified actions to assess and plan for such impacts. The final 2009 California
Climate Adaptation Strategy report was issued in December 2009 (CNRA 2009a), and an update,
Safeguarding California: Reducing Climate Risk, followed in July 2014 (CNRA 2014). To
assess the state’s vulnerability, the report summarizes key climate change impacts to the state for
the following areas: Agriculture, Biodiversity and Habitat, Emergency Management, Energy,
Forestry, Ocean and Coastal Ecosystems and Resources, Public Health, Transportation, and
Air Quality and Greenhouse Gas Emissions Analysis

Water. Issuance of the Safeguarding California: Implementation Action Plans followed in March
2016 (CNRA 2016). Presently, a draft of the Safeguarding California Plan: 2017 Update is
being prepared to communicate current and needed actions that the state government should take
to build climate change resiliency (CNRA 2017).
2015 State of the State Address. In January 2015, Governor Brown in his inaugural address and
annual report to the Legislature established supplementary goals that would further reduce GHG
emissions over the next 15 years. These goals include an increase in California’s renewable
energy portfolio from 33% to 50%, a reduction in vehicle petroleum use for cars and trucks by
up to 50%, measures to double the efficiency of existing buildings, and decreasing emissions
associated with heating fuels.
2016 State of the State Address . In his January 2016 address, Governor Brown established a
statewide goal to bring per capita GHG emission s down to two tons per person, which reflects
the goal of the Global Climate Leadership Memorandum of Understanding to limit global
warming to less than 2°C by 2050. The Global Climate Leadership Memorandum of
Understanding agreement pursues emission reductions of 80% to 95% below 1990 levels by
2050 and/or reach a per -capita annual emissions goal of less than two metric tons by 2050. A
total of 187 jurisdictions representing 38 countries and 6 continents, including California, have
signed or endorsed the Global Climate Leadership Memorandum of Understanding (Under 2
Coalition 2017).
3.2.3 Local Regulations
3.2.3.1 San Diego Air Pollution Control District
The San Diego Air Pollution Control District (SDAPCD) does not have established GHG rules,
regulations, or policies.
3.2.3.2 City of Chula Vista
International Council of Environmental Initiatives Local Governments for Sustainability.
In 1992, the City of Chula Vista participated in the Cities for Climate Protection Program, which
aimed at developing municipal action plans for the reduction of GHGs. This program was
sponsored and developed by the International Council of Environmental Initiatives and the
United Nations Environment Program in response to the United Nations Framework Convention
on Climate Change, while recognizing that all local planning and development has direct
consequences on energy consumption, and cities exercise key powers over urban infrastructure,
including neighborhood design, and over transportation infrastructure, such as roads, streets,
pedestrian areas, bicycle lanes, and public transport.

Chula Vista Carbon Dioxide (CO2) Reduction Plan. Each participant in the International
Council of Environmental Initiatives program was to create local policy measures to ensure
multiple benefits to the City and, at the same time, identify a carbon reduction goal through the
implementation of those measures. The carbon reduction goal was to fit within the realm of
international climate treaty reduction goals.
In its CO2 Reduction Plan, developed in 1996 and officially adopted in 2000, Chula Vista
committed to lowering its CO2 emissions by diversifying its transportation system and using
energy more efficiently in all sectors. To focus efforts in this direction, Chula Vista adopted the
international CO2 reduction goal of returning to pre-1990 levels by 2010. In order to achieve this
goal, eight actions were identified, which when fully implemented, were anticipated to save
100,000 tons of CO2 each year.
As a result of the 2005 GHG Emissions Inventory Report, in May 2007, staff reported to the City
Council that citywide GHG emissions had increased by 35% (mainly due to residential growth)
from 1990 to 2005, while emissions on a per capita basis and from municipal operations
decreased by 17% and 18%, respectively. The City Council directed staff to convene a Climate
Change Working Group to develop recommendations to reduce the community’s GHGs in order
to meet the City’s 2010 GHG emissions reduction targets.
As a result of the 2012 GHG Emissions Inventory Report, staff reported to the City Council that
citywide GHG levels are 1,011,481 MT CO2E. Compared to 2005, Chula Vista’s citywide GHG
emissions have increased by 8%. However, 2012 per capita emissions are approximately 5% below
2005 levels and 33% below 1990 levels. Unlike the last two inventories, 2009 and 2010, there was
a slight increase in citywide energy consumption over the last couple of years due most likely to
local economic recovery. As with past inventories, community transportation activity has
continued increasing with 2012 vehicle miles traveled (VMT) about 29% higher than in 2005. In
order to reach the current community emissions reduction goal of 20% below 1990 emission
levels, the City will have to reduce its GHG emissions by more than 359,332 MT CO2E (35%);
however, statewide initiatives are expected to help achieve some of these reductions by 2020.
Climate Change Working Group. The Climate Change Working Group, which is composed of
residents, businesses, and community organization representatives, helps the city develop
climate-related programs and policies. In 2008, the group reviewed over 90 carbon reduction
measures and ultimately chose seven measures to recommend for adoption to the City Council,
which the council subsequently adopted. The measures were designed to reduce or mitigate
climate change impacts by reducing GHG emissions within Chula Vista to 20% below 1990
levels, in keeping with its CO2 Reduction Plan and United Nations Framework Convention on
Climate Change goals.

In October 2009, the City Council directed the group to evaluate how the City could adapt to
potential climate change impacts. The group met throughout 2011 to develop recommendations
based on the City’s vulnerabilities and risks to climate change. In May 2011, the group adopted
the Climate Adaptation Strategies – Implementation Plans, described below, and in 2014, the
group released the 2014 Climate Action Plan Update – Recommendations, described below.
Chula Vista Climate Adaptation Strategies – Implementation Plans. The Climate
Adaptation Strategies – Implementation Plans document developed by the Climate Change
Working Group includes 11 strategies to facilitate Chula Vista’s adaptation to the potential
impacts of global climate change related to energy and water supply, public health, wildfires,
ecosystem management, coastal infrastructure, and local economy sectors. The strategies
include cool paving, shade trees, cool roofs, local water supply and reus e, stormwater pollution
prevention and reuse, education and wildfires, extreme heat plans, open space management,
wetlands preservation, sea level rise and land development codes, and green economy. For
each strategy, the plans outline specific implementat ion components, critical steps, costs, and
timelines. In order to limit the necessary staffing and funding required to implement the
strategies, the plans were also designed to build upon existing municipal efforts , rather than
create new, standalone polic ies or programs. Initial implementation of all 11 strategies were
phased over a 3-year period after adoption of the plan in 2011.
Chula Vista Climate Protection Measures. On July 10, 2008, the City Council adopted
implementation plans for seven climate protection measures to reduce GHG emissions to 20%
below 1990 levels by 2012. The implementation plans outline the detailed strategy for initiating,
funding, and tracking the following measures:
1. Clean Vehicle Replacement Policy for City Fleet: When City fleet vehicles are retired,
they will be replaced through the purchase or lease of alternative fuel or hybrid
substitutes. In addition, the City fleet will begin to pursue installing new fuel tanks to
allow heavy-duty vehicles to convert to biodiesel fuel immediately.
2. Clean Vehicle Replacement Policy for City-Contracted Fleets: As contracts for City-
contracted fleet services (such as transit buses, trash haulers and street sweeper trucks)
are renewed, the City will encourage contractors to replace their vehicles with alternative
fuel or hybrid substitutes through the contract bid process. In addition, the City will
pursue implementing two hydrogen vehicle demonstration projects.
3. Business Energy Evaluations: Businesses with storefronts or offices need to participate
in a no-cost energy assessment of their facilities to help identify opportunities for them to
reduce monthly energy costs. The business assessment will be integrated into the existing
business licensing process and codified through a new municipal ordinance.

71 December 2018
4. Green Building Standard: The City will implement a citywide, mandatory green building
standard for new residential and non-residential construction projects and major
renovations. The standard includes four components: 1) adopting a citywide Green
Building Standard, 2) adopting a citywide Enhanced Energy Efficiency Standard, 3)
launching a Green Building Awareness program for builders, permit applicants and the
general public, and 4) developing design guidelines for sustainable development.
5. Solar and Energy Efficiency Conversion Program: The City will create a community
program to provide residents and businesses with a streamlined, cost-effective
opportunity to implement energy efficiency improvements and to install solar/renewable
energy systems on their properties. The City will develop a funding mechanism to allow
program participants to voluntarily choose to place the improvement costs on their
property’s tax rolls, thereby avoiding large upfront capital costs. In addition, the program
will promote vocational training, local manufacturing, and retail sales opportunities for
environmental products and services. To help stimulate the private -sector renewable
market and lower the cost for installing renewable energy systems on new homes, the
City will require all new residential buildings to include pre-wiring and pre-plumbing for
solar photovoltaic and solar hot water systems, respectively.
6. Smart Growth Around Trolley Stations: The City will continue to implement the smart
growth design principles, which promote mixed-use and walkable and transit -friendly
development, particularly in and around the E, H, and Palomar trolley stations. These
principles were emphasized in the revised Chula Vista General Plan and the Urban
Core Specific Plan. In particula r, the City will initiate site planning, design studies and
specific area plan development to further support smart growth development that
complements GHG reductions.
7. Turf Lawn Conversion Program: The City will create a community program to
provide residents and businesses with a streamlined, cost -effective opportunity to
replace their turf lawns with water -saving landscaping and irrigation systems. Some
municipal turf lawn areas (such as medians, fire stations and non -recreational park
areas) will also be converted to act as public demonstration sites and to reduce monthly
water costs. The City will establish the model for water -wise landscaping for new
development through an update of the Chula Vista Municipal Landscape Ordinance and
Water Conservation Plan guidelines.
Chula Vista Climate Protection Measures – 2013 Progress Report. Since 2000, Chula Vista
has been implementing a “Climate Action Plan” (CO2 Reduction Plan) to address the threat of
climate change to the local community. This original plan has been revised to incorporate new
climate mitigation (2008) and adaptation (2011) measures to strengthen the City’s climate
Air Quality and Greenhouse Gas Emissions Analysis

10271
72 December 2018
action efforts and to facilitate the numerous community co-benefits, such as utility savings,
better air quality, reduced traffic congestion, local economic development, and improved
quality of life. Based on available funding, staff has been implementing the 18 climate -related
actions and their 57 as sociated components. Overall, 70% of the components have been
successfully completed and/or are being implemented on an ongoing basis, which represents a
7% increase since the last reporting period. Another 26% are still being actively pursued, while
only two components remain on hold (City of Chula Vista 2013).
2014 Climate Action Plan Update – Recommendations by the Climate Change Working
Group. The Climate Change Working Group has been evaluating new opportunities to help
reach the Chula Vista Climate Action Plan’s GHG gas reduction goal of 30% below 2005 levels.
As such, they have identified the following 12 action areas that could generate up to 166,000 MT
in reductions by 2020, while improving local air quality, generating utility savings, reducing
traffic congestion, and promoting a healthier community (City of Chula Vista 2014).
2017 Climate Action Plan. The latest version of the Climate Action Plan (CAP) was adopted on
September 26, 2017, by the City Council and provides updated goals, policies, actions, and the
latest city-wide inventory and projections. The CAP is not considered a CEQA “qualified” plan
under CEQA Guidelines Section 15183.5, as it has not been adopted in a public process following
environmental review. The Climate Change Working Group has been evaluating new opportunities
to help reach the Chula Vista Climate Action Plan’s GHG gas reduction goals which are based on
the Scoping Plan Update goals of 6 MT CO2E per person by 2030 and 2 MT CO2E per person by
2050. As such, they have identified the following 11 action areas that could generate up to 208,220
MT in reductions by 2020, while improving local air quality, generating utility savings, reducing
traffic congestion, and promoting a healthier community (City of Chula Vista 2017):

Chula Vista Green Building Standards. Consistent with Measure 4 of the Chula Vista Climate
Protection Measures, the City Council adopted the Green Building Standards Ordinance
(Ordinance No. 3140) on October 6, 2009, which became effective November 5, 2009. The
Green Building Standards ordinance includes standards for energy efficiency, pollutant controls,
interior moisture control, improved indoor air quality and exhaust, indoor water conservation,
stormwater management, and construction waste reduction and recycling.
Building permit applications are required to indicate on project construction plans and specifications
the Green Building Standards measures that comply with the ordinance. Prior to final building
approval or issuance of a certificate of occupancy, the Building Official reviews the information
submitted by the applicant and determines whether the applicant has constructed the project in
accordance with the permitted plans and documents, and whether the plans are in compliance with
Air Quality and Greenhouse Gas Emissions Analysis

the Green Building Standards. In 2013, Chula Vista adopted the Green Building Code, called
CalGreen, for Residential and Non-residential development effective January 1, 2014.
Chapter 15.12 Green Building Standards. Title 24, Part 11, was adopted as the Green Building
Code of the City of Chula Vista for enhancing the design and construction of buildings, building
additions and alterations through the use of building concepts having a reduced negative impact
or positive environmental impact and encouraging sustainable construction practices, excepting
such portions as are hereinafter deleted, modified, or amended.
Chula Vista Increased Energy Efficiency Standards. On January 26, 2010, the City Council
adopted the Increased Energy Efficiency Standards Ordinance (Ordinance No. 3149). This
ordinance became effective February 26, 2010, as Section 15.26 of the municipal code. Permit
applications are required to comply with these energy efficiency standards.
Chula Vista Municipal Code Section 15.26.030 requires permit applications to comply with
increased energy efficiency standards that achieve 15% to 20% greater efficiency than the
requirements of the Title 24 2008 standards, depending on climate zone. The City falls within two
climate zones, Zone 7 and Zone 10. The project site is within Zone 7. For Zone 7, the code requires:
All new low-rise residential building or additions, remodels or alterations to existing low-
rise residential buildings where the additions, remodels or alterations are greater than
1,000 square feet of conditional floor area, shall use at least 15% less energy than the
2008 Title 24 Building Energy Efficiency Standards allow; and
All new non-residential, high-rise residential or hotel/motel buildings, or additions,
remodels or alterations to existing non-residential, high-rise residential or hotel/motel
buildings where the additions, remodels or alterations are greater than 10,000 square feet
of conditioned floor area, shall use at least 15% less energy than the 2008 Title 24
Building Energy Efficiency Standards.
No city building permit shall be issued unless the permit application demonstrates to the
Building Official compliance with the requirements of Section 15.26.030. Compliance is
to be demonstrated based on a performance approach, using a CEC -approved energy
compliance software program, as specified in the Title 24 2008 Building Energy
Efficiency Standards.
In 2013, Chula Vista adopted the Energy Code for Residential and Non -Residential
development, effective July 1, 2014. Energy Efficiency measures adopted by the Chula Vista
Municipal Code are as follows:
Section 15.26.010 - California Energy Code. The California Energy Code is adopted as
the energy code of the City for the purpose of regulating building design and construction

individual single-family home construction, remodel, addition or renovation, shall submit
a Waste Management Report only (no deposit required).
All City projects.
Covered projects must submit a waste management plan to the Chula Vista Public Works
Department, Environmental Services Division, which must be reviewed and approved prior to
the issuance of a demolition or building permit. The waste management plan will indicate how
the applicant will recycle and/or reuse 90% of inert materials and at least 50% of the remaining
construction and demolition debris generated from the project.
City of Chula Vista Clean Transportation Energy Roadmap (2012). The Clean
Transportation Energy Roadmap (“Roadmap”) can serve as a resource for the City of Chula
Vista as it continues to promote clean transportation measures, both in its municipal operations
and in the community. The Roadmap identifies petroleum reduction measures and tools specific
to the City that generally result in cost savings and benefits to the environment, including:
An assessment of alternative fuel vehicles and fuel availability for the City’s vehicle fleet.
Commuter programs, including vanpools, carpools, and teleworking that the City could
promote to its employees.
Online tools to establish a baseline of petroleum consumed and GHGs emitted from
employee commutes, as well as annual tracking tools.
Smart growth and active transportation policies that enhance local walking and
biking options.
Outreach materials on Clean Transportation programs that can be shared with local
residents, schools, and businesses.
The Roadmap also recognizes the significant steps that the City has taken already. Since 2000,
Chula Vista has been implementing a “Climate Action Plan” (CO2 Reduction Plan) that includes
measures to reduce energy and fuel use at municipal facilities and throughout the community.
City of Chula Vista General Plan. The City of Chula Vista General Plan (City of Chula Vista
2005) includes various policies related to reducing GHG emissions (both directly and indirectly).
Applicable policies include the following:
Land Use and Transportation Element
Policy LUT-23.1: Encourage the use of bicycles and walking as alternatives to driving.

3.3 Greenhouse Gas Inventories and Climate Change Conditions
3.3.1 Sources of Greenhouse Gas Emissions
Global Inventory
Anthropogenic GHG emissions worldwide in 2012 (the most recent year for which data is
available) totaled approximately 44,816 million metric tons (MMT) CO2E (WRI 2015). Six
countries—China, the United States, the Russian Federation, India, Japan, and Brazil—and the
European community accounted for approximately 65% of the total global emissions,
approximately 29,300 MMT CO2E (WRI 2015). Table 12 presents the top GHG-emissions-
producing countries.

National and State Inventories
Per the EPA’s Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990–2015 (EPA 2017b),
total U.S. GHG emissions were approximately 6,586.7 MMT CO2E in 2015. The primary GHG
emitted by human activities in the United States was CO2, which represented approximately 82.2%
of total GHG emissions (5,411.4 MMT CO2E). The largest source of CO2, and of overall GHG

emissions, was fossil-fuel combustion, which accounted for approximately 93.3% of CO2 emissions
in 2015 (5,049.8 MMT CO2E). Relative to 1990, gross United States GHG emissions in 2015 are
higher by 3.5%, down from a high of 15.5% above 1990 levels in 2007. GHG emissions decreased
from 2014 to 2015 by 2.3% (153.0 MMT CO2E) and overall, net emissions in 2015 were 11.5%
below 2005 levels (EPA 2017c).
According to California’s 2000–2015 GHG emissions inventory (2017 edition), California
emitted 440.36 MMT CO2E in 2015, including emissions resulting from out-of-state electrical
generation (CARB 2017a). The sources of GHG emissions in California include transportation,
industrial uses, electric power production from both in-state and out-of-state sources, commercial
and residential uses, agriculture, high GWP substances, and recycling and waste. The California
GHG emission source categories (as defined in CARB’s 2008 Scoping Plan) and their relative
contributions in 2015 are presented in Table 13.

3.3.2 Potential Effects of Climate Change
Globally, climate change has the potential to affect numerous environmental resources through
uncertain impacts related to future air temperatures and precipitation patterns. The 2014
Intergovernmental Panel on Climate Change Synthesis Report indicated that warming of the climate
system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over
decades to millennia. Signs that global climate change has occurred include warming of the
atmosphere and ocean, diminished amounts of snow and ice, and rising sea levels (IPCC 2014).
In California, climate change impacts have the potential to affect sea level rise, agriculture, snowpack
and water supply, forestry, wildfire risk, public health, and electricity demand and supply (CCCC
2006). The primary effect of global climate change has been a 0.2° Celsius (°C) rise in average
global tropospheric temperature per decade, determined from meteorological measurements
worldwide between 1990 and 2005. Scientific modeling predicts that continued emissions of GHGs
at or above current rates would induce more extreme climate changes during the 21st century than
were observed during the 20th century. A warming of about 0.2°C (0.36° Fahrenheit (°F)) per decade
is projected, and there are identifiable signs that global warming could be taking place.
Although climate change is driven by global atmospheric conditions, climate change impacts are
felt locally. A scientific consensus confirms that climate change is already affecting California.
The average temperatures in California have increased, leading to more extreme hot days and
fewer cold nights; shifts in the water cycle have been observed, with less winter precipitation
falling as snow, and both snowmelt and rainwater running off earlier in the year; sea levels have
risen; and wildland fires are becoming more frequent and intense due to dry seasons that start
earlier and end later (CAT 2010).
An increase in annual average temperature is a reasonably foreseeable effect of climate change .
Observed changes over the last several decades across the Western United States reveal clear
signals of climate change. Statewide average temperatures increased by about 1.7°F from 1895
to 2011, and warming has been the greatest in the Sierra Nevada (CCCC 2012). By 2050,
California is projected to warm by approximately 2.7°F above 2000 averages, a threefold
increase in the rate of warming over the last century. By 2100, average temperatures could
increase by 4.1 to 8.6°F, depending on emissions levels. Springtime warming—a critical
influence on snowmelt—will be particularly pronounced. Summer temperatures will rise more
than winter temperatures, and the increases will be greater in inland California, compared to the
coast. Heat waves will be more frequent, hotter, and longer. There will be fewer extremely cold
nights (CCCC 2012). A decline of Sierra snowpack, which accounts for approximately half of
the surface water storage in California and much of the state’s water supply, by 30% to as much
as 90% is predicted over the next 100 years (CAT 2006).

Model projections for precipitation over California continue to show the Mediterranean pattern
of wet winters and dry summers with seasonal, year-to-year, and decade-to-decade variability.
For the first time, however, several of the improved climate models shift toward drier conditions
by the mid-to-late 21st century in Central and, most notably, Southern California. By late-
century, all projections show drying, and half of them suggest 30-year average precipitation will
decline by more than 10% below the historical average (CCCC 2012).
A summary of current and future climate change impacts to resource areas in California, as discussed
in the Safeguarding California: Reducing Climate Risk (CNRA 2014), is provided below.
Agriculture. The impacts of climate change on the agricultural sector are far more severe than the
typical variability in weather and precipitation patterns that occur year to year. The agriculture
sector and farmers face some specific challenges that include more drastic and unpredictable
precipitation and weather patterns; extreme weather events that range from severe flooding and
extreme drought to destructive storm events; significant shifts in water availably and water quality;
changes in pollinator lifecycles; temperature fluctuations, including extreme heat stress and
decreased chill hours; increased risks from invasive species and weeds, agricultural pests, and plant
diseases; and disruptions to the transportation and energy infrastructure supporting agricultural
production. These challenges and associated short-term and long-term impacts can have both
positive and negative effects on agricultural production. Nonetheless, it is predicted that current
crop and livestock production will suffer long-term negative effects resulting in a substantial
decrease in the agricultural sector if not managed or mitigated.
Biodiversity and Habitat. The state’s extensive biodiversity stems from its varied climate and
assorted landscapes, which have resulted in numerous habitats where species have evolved and
adapted over time. Specific climate change challenges to biodiversity and habitat include species
migration in response to climatic changes, range shift and novel combinations of species;
pathogens, parasites, and disease; invasive species; extinction risks; changes in the timing of
seasonal life-cycle events; food web disruptions; and threshold effects (i.e., a change in the
ecosystem that results in a “tipping point” beyond which irreversible damage or loss has occurs).
Habitat restoration, conservation, and resource management across California and through
collaborative efforts among public, private, and nonprofit agencies has assisted in the effort to
fight climate change impacts on biodiversity and habitat. One of the key m easures in these
efforts is ensuring species’ ability to relocate as temperature and water availability fluctuate as a
result of climate change based on geographic region.
Energy. The energy sector provides California residents with a supply of reliable and affordable
energy through a complex integrated system. Specific climate change challenges for the energy
sector include temperature, fluctuating precipitation patterns, increasing extreme weather events ,
Air Quality and Greenhouse Gas Emissions Analysis

and sea level rise. Increasing temperatures and reduced snowpack negatively impact the
availability of a steady flow of snowmelt to hydroelectric reservoirs. Higher temperatures also
reduce the capacity of thermal power plants, since power plant cooling is less efficient at higher
ambient temperatures. Increased temperatures will also increase electricity demand associated
with air conditioning. Natural gas infrastructure in Coastal California is threatened by sea level
rise and extreme storm events.
Forestry. Forests occupy approximately 33% of California’s 100 million acres and provide key
benefits, such as wildlife habitat, absorption of CO2, renewable energy, and building materials.
The most significant climate change–related risks to forests are accelerated risk of wildfire and
more frequent and severe droughts. Droughts have resulted in more large-scale mortalities and,
combined with increasing temperatures, have led to an overall increase in wildfire risks.
Increased wildfire intensity subsequently increases public safety risks, property damage, fire
suppression and emergency response costs, watershed and water quality impacts , and vegetation
conversions. These factors contribute to decreased forest growth, geographic shifts in tree
distribution, loss of fish and wildlife habitat, and decreased carbon absorption. Climate change
may result in increased establishment of non-native species, particularly in rangelands where
invasive species are already a problem. Invasive species may be able to exploit temperature or
precipitation changes or quickly occupy areas denuded by fire, insect mortality, or other climate
change effects on vegetation.
Ocean and Coastal Ecosystems and Resources. Sea level rise, changing ocean conditions, and
other climate change stressors are likely to exacerbate long-standing challenges related to ocean
and coastal ecosystems in addition to threatening people and infrastructure located along the
California coastline and in coastal communities. Sea level rise, in addition to more frequent and
severe coastal storms and erosion, are threatening vital infrastructure, such as roads, bridges,
power plants, ports and airports, gasoline pipes, and emergency facilities, as well as negatively
impacting the coastal recreational assets, such as beaches and tidal wetlands. Water quality and
ocean acidification threaten the abundance of seafood and other plant and wildlife habitats
throughout California and globally.
Public Health. Climate change can impact public health through various environmental changes
and is the largest threat to human health in the 21st century. Changes in precipitation patterns
affect public health primarily through potential for altered water supplies, and extreme events ,
such as heat, floods, droughts, and wildfires. Increased frequency, intensity, and duration of
extreme heat and heat waves is likely to increase the risk of mortality due to heat -related illness,
as well as exacerbate existing chronic health conditions. Other extreme weather events are likely
to negatively impact air quality and increase or intensify respiratory illness, such as asthma and
allergies. Additional health impacts that may be impacted by climate change include
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
85 December 2018
cardiovascular disease, vector-borne diseases, mental health impacts, and malnutrition injuries.
Increased frequency of these ailments is likely to subsequently increase the direct risk of injury
and/or mortality.
Transportation. Residents of California rely on airports, seaports, public transportation, and an
extensive roadway network to gain access to destinations, goods, and services. While the
transportation industry is a source of GHG emissions, it is also vulnerable to climate change
risks. Particularly, sea level rise and erosion threaten many coastal California roadways, airports,
seaports, transit systems, bridge supports, and energy and fueling infrastructure. Increasing
temperatures and extended periods of extreme heat threaten the integrity of the roadways and rail
lines. High temperatures cause the road surfaces to expand, which leads to increased pressure
and pavement buckling. High temperatures can also cause rail breakages, which could lead to
train derailment. Other forms of extreme weather events, such as extreme storm events, can
negatively impact infrastructure, which can impair movement of peoples and goods, or
potentially block evacuation routes and emergency access roads. Increased wildfires, flooding,
erosion risks, landslides, mudslides, and rockslides can all profoundly impact the transportation
system and pose a serious risk to public safety.
Water. Water resources in California support residences, plants, wildlife, farmland, landscapes,
and ecosystems and bring trillions of dollars in economic activity. Climate change could
seriously impact the timing, form, amount of precipitation, runoff patterns, and frequenc y and
severity of precipitation events. Higher temperatures reduce the amount of snowpack and lead to
earlier snowmelt, which can impact water supply availability, natural ecosystems , and winter
recreation. Water supply availability during the intense dry summer months is heavily dependent
on the snowpack accumulated during the winter. Increased risk of flooding has a variety of
public health concerns, including water quality, public safety, property damage, displacement,
and post-disaster mental health problems. Prolonged and intensified droughts can also negatively
affect groundwater reserves and result in increased overdraft and subsidence. Droughts can also
negatively impact agriculture and farmland throughout the state. The higher risk of wildfires can
lead to increased erosion, which can negatively impact watersheds and result in poor water
quality. Water temperatures are also prone to increase, which can negatively impact wildlife that
rely on a specific range of temperatures for suitable habitat.
In May 2017, the California Natural Resources Agency (CNRA) released the draft
Safeguarding California Plan: 2017 Update , which is a survey of current programmatic
responses for climate change and contains recommendations for further actions (CNRA 2017).

3.4 Significance Criteria and Methodology
3.4.1 Thresholds of Significance
The significance criteria used to evaluate the project’s GHG emissions impacts is based on
the recommendations provided in Appendix G of the CEQA Guidelines . For the purposes of
this GHG emissions analysis, the project would have a significant environmental impact if it
would (14 CCR 15000 et seq.):
1. Generate GHG emissions, either directly or indirectly, that may have a significant impact
on the environment?
2. Conflict with an applicable plan, policy, or regulation adopted for the purpose of
reducing the emissions of GHGs?
Global climate change is a cumulative impact; a project participates in this potential impact
through its incremental contribution combined with the cumulative increase of all other sources
of GHGs. There are currently no established thresholds for assessing whether the GHG
emissions of a project, such as the Project, would be considered a cumulatively considerable
contribution to global climate change; however, all reasonable efforts should be made to
minimize a project’s contribution to global climate change. In addition, while GHG impacts are
recognized exclusively as cumulative impacts (CAPCOA 2008), GHG emissions impacts must
also be evaluated on a project-level under CEQA.
The CEQA Guidelines do not prescribe specific methodologies for performing an assessment, do
not establish specific thresholds of significance, and do not mandate specific mitigation
measures. Rather, the CEQA Guidelines emphasize the lead agency’s discretion to determine the
appropriate methodologies and thresholds of significance consistent with the manner in which
other impact areas are handled in CEQA (CNRA 2009a). The State of California has not adopted
emissions-based thresholds for GHG emissions under CEQA. The Governor’s Office of Planning
and Research’s Technical Advisory titled “CEQA and Climate Change: Addressing Climate
Change through California Environmental Quality Act Review” states that “public agencies are
encouraged but not required to adopt thresholds of significance for environmental impacts. Even
in the absence of clearly defined thresholds for GHG emissions, the law requires that such
emissions from CEQA projects must be disclosed and mitigated to the extent feasible whenever
the lead agency determines that the project contributes to a significant, cumulative climate
change impact” (OPR 2008). Furthermore, the advisory document indicates that “in the absence
of regulatory standards for GHG emissions or other scientific data to clearly define what
constitutes a ‘significant impact,’ individual lead agencies may undertake a project -by-project
analysis, consistent with available guidance and current CEQA practice.” Section 15064.7(c) of
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
87 December 2018
the CEQA Guidelines specifies that “when adopting thresholds of significance, a lead agency
may consider thresholds of significance previously adopted or recommended by other public
agencies, or recommended by experts, provided the decision of the lead agency to adopt such
thresholds is supported by substantial evidence.”
Neither the State of California nor the SDAPCD has adopted emission -based thresholds of
significance for GHG emissions under CEQA.
An efficiency threshold sets a per capita emissions limit. The total emissions from a given
project are summed and divided by a project’s service population7 (SP) to determine emissions
per capita and are compared to the efficiency threshold. Efficiency thresholds have been
proposed by various agencies and air districts including both the Bay Area Air Quality
Management District and South Coast Air Quality Management District (SCAQMD). The Bay
Area Air Quality Management District and SCAQMD have each developed an efficiency
threshold of 6.6 MT CO2E/SP for plan level developments. Additionally, the Bay Area Air
Quality Management District suggested a project level efficiency threshold of 4.6 MT CO2E per
SP, while the SCAQMD suggested a project level efficiency threshold of 4.8 MT CO2E per SP.
The fault in these proposed thresholds is that they rely on CARB’s scoping plan reduction goal
and statewide population for 2020. The California Supreme Court’s decision on the Center for
Biological Diversity vs. California Department of Fish and Wildlife determined project level
analyses should not rely on statewide data. A more localized efficiency threshold must be
developed based on the population at the City level. These thresholds were developed assuming
compliance with AB 32 2020 goals.
To develop an efficiency threshold that would satisfy the requirements of Center for Biological
Diversity vs. California Department of Fish and Wildlife and EO B-30-15, the City’s 1990
emissions inventory, less 40%, must be divided by the City’s 2030 population. Project level
emissions can then be directly evaluated against a threshold based on local emission reduction
goals and local population densities in accordance with the Court’s decision on Center for
Biological Diversity vs. California Department of Fish and Wildlife.
As provided in the City’s 2012 Greenhouse Gas Emissions Inventory, the City’s 1990 GHG
emissions inventory totals approximately 847,166 MT CO2E. Based on the 1990 US Census (US
Census Bureau 1992), the City’s SP in 1990 was 235,344 (135,243 residents + 100,101 employees).
Dividing the City’s 1990 GHG emissions of 847,166 MT CO2E by the 1990 SP gives an efficiency
metric of 3.60 MT CO2E per SP.
7 Service population is defined as the number of residents plus the number of employees within the City.
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
88 December 2018
Consistent with EO B-30-15, the City’s 2030 goal is 508,300 MT CO2E (847,166 x [1-0.40]). Based
on SANDAG Series 13 model (SANDAG 2013), the City’s SP in 2030 is estimated at 407,525
(313,474 residents + 94,050 employees)8. Dividing the City’s 2030 GHG emissions goal by the
City’s 2030 population results in an efficiency metric of 1.25 MT CO2E per SP.
In order to develop an efficiency metric for the Project’s buildout year of 2021, it is necessary to
interpolate between the efficiency metrics in 1990 and 2030. Table 16 below shows the
calculated efficiency metric for 2021, which is consistent with EO B-30-15.
Table 16
2021 Interpolated Efficiency Metric
1990 Efficiency Metric (MT/SP/yr) 2030 Efficiency Metric (MT/SP/yr) 2021 Efficiency Metric1 (MT/SP/yr)
3.60 1.25 1.78
Notes: MT = metric ton; SP = service population; yr = year
1 The 2021 efficiency metric was calculated as follows: (((2030 Efficiency Metric – 1990 Efficiency Metric) ÷ (2030 – 1990)) × (2021 – 1990)) + (1990
Efficiency Metric).
As shown in Table 16, the calculated efficiency metric for 2021 based on the City’s emissions
inventory in 2012 and GHG emissions reduction goal for 2030 was 1.78 MT CO2E per SP. If the
Project achieves the 2021 efficiency metric, it would not interfere with attainment of the 2030 and
2050 statewide emission reduction targets, and therefore not interfere with the State’s and the
City’s ability to achieve the mid-term and long-term GHG reduction targets in the City’s CAP.
3.4.2 Approach and Methodology
As discussed in Section 3.1.2, Greenhouse Gases and Global Warming Potential, this analysis
assumes that the GWP for CH4 is 25 and the GWP for N2O is 298, based on the IPCC Fourth
Assessment Report (IPCC 2007).
3.4.2.1 Construction
CalEEMod Version 2016.3.2 was used to estimate potential Project-generated GHG emissions
during construction. Construction of the Project would result in GHG emissions primarily
associated with use of off-road construction equipment, on-road hauling and vendor (material
delivery) trucks, and worker vehicles. All details for construction criteria air pollutants discussed
in Section 2.4.2.1, are also applicable for the estimation of construction-related GHG emissions.
8 The SANDAG Series 13 model provides forecasts for years 2020 and 2035. The forecast for year 2030 was
interpolated using the forecasts for 2020 and 2035.
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
89 December 2018
As such, see Section 2.4.2.1 for a discussion of construction emissions calculation methodology
and assumptions.
3.4.2.2 Operation
CalEEMod Version 2016.3.2 was used to estimate potential Project-generated operational GHG
emissions from area sources (landscape maintenance), energy sources (natural gas and
electricity), mobile sources, solid waste, and water supply and wastewater treatment. Emissions
from each category are discussed in the following text with respect to the Project. For additional
details, see Section 2.4.2.3, Operation, for a discussion of operational emission calculation
methodology and assumptions, specifically for area, energy (natural gas), and mobile sources.
Operational year 2021 was assumed consistent with the Project’s traffic report.
Energy Sources
As represented in CalEEMod, energy sources include GHG emissions associated with building
electricity and natural gas usage (non-hearth). Electricity use would contribute indirectly to
GHGs, since GHG emissions occur at the site of the power plant, which is typically off site.
Emissions were calculated by mult iplying the energy use by the utility’s carbon intensity
(pounds of GHGs per megawatt -hour for electricity or 1,000 British thermal units for natural
gas) for CO2 and other GHGs. Annual natural gas (non -hearth) and electricity emissions were
estimated in CalEEMod using the emissions factors for SDG&E, which would be the energy
source provider for the Proposed Project. For the operational year 202 1, the emission factors
for SDG&E were adjusted to reflect SDG&E’s compliance with the RPS standards. A
renewable procurement percentage of 43% was achieved in 2016 as reported by the California
Energy Commission and thus is a conservative estimate of the renewable mix for 2021 since
the RPS goal for 2030 is 50% (California Energy Commission 2017).
CalEEMod default values for energy consumption for each land use were applied for the Project
analysis. The energy use from residential land uses is calculated in CalEEMod based on the
California Residential End-Use Survey database. The program uses data collected during the
Residential Appliance Saturation Survey to develop energy intensity values (electricity and
natural gas usage per square foot per year) for residential buildings. Energy use in buildings
(both natural gas and electricity) is divided by the program into end use categories subject to
Title 24 requirements (end uses associated with the building envelope, such as the HVAC
system, water heating system, and integrated lighting) and those not subject to Title 24
requirements (such as appliances, electronics, and miscellaneous “plug-in” uses).
Air Quality and Greenhouse Gas Emissions Analysis
Technical Report for the Bonita Glen Project
10271
90 December 2018
Title 24 of the California Code of Regulations serves to enhance and regulate California’s
building standards. The most recent amendments to Title 24, Part 6, referred to as the 2016
standards, became effective on January 1, 2017. The previous amendments were referred to as
the 2013 standards. CalEEMod 2016.3.2 includes compliance with the 2016 Title 24 standards.
The Project applicant is committed to exceeding the 2016 Title 24 energy standards. The Project
includes implementation of rooftop solar photovoltaic energy production, which will cover
energy use for all common area lighting. The Project will include the installation of electric
vehicle charging stations, Energy Star appliances, and 100% of the lighting fixtures on site will
be light-emitting diodes (LED).
Solid Waste
The Project would generate solid waste and would, therefore, result in CO2E emissions associated
with landfill off-gassing. Solid waste generation was derived from the CalEEMod default rates for
each land use type. Emission estimates associated with solid waste were estimated using CalEEMod.
These rates, last updated in 2013, provide solid waste generation for different land use types before
prior to diversion (Qiguo, pers. comm. 2018). A solid waste diversion rate of 75% was assumed in
accordance with AB 341 and 939.
Water Supply and Wastewater
Water supplied to the Project requires the use of electricity. Accordingly, the supply,
conveyance, treatment, and distribution of water would indirectly result in GHG emissions
through use of electricity. Annual water use for the Project and GHG emissions associated with
the electricity used for water supply were calculated based upon default water use estimates for
each land-use type, as estimated by CalEEMod and San Diego Gas and Electric factors. The
Project would include low-flow fixtures in all buildings and use non-potable water for irrigation
of the parks and greenbelts. Additional reclaimed water will be available for the Project to use,
but as a conservative measure, it was only assumed to be used for the parks and greenbelts.
Project Service Population
As previously discussed, a project’s “service population” refers to a project’s residents plus
employees that would be generated by the project. To estimate the residents for the Project, the
persons per household ratio for 2020 and 2035 from SANDAG’s Series 13 forecast were used to
extrapolate the persons per household ratio for 2021, as shown in Table 17.

2035 326,625 101,188 3.228
2021 – – 3.2211
Source: The population and household data are based on the household population and total housing units data in the in San Diego
Association of Government’s Series 13 Regional Growth Forecast (SANDAG 2013) for the City.
1 The 2021 persons per household was calculated as follows: (((2035 Persons Per Household – 2020 Persons Per Household) ÷ (2035 – 2020)) ×
(2021 – 2020)) + (2020 Persons Per Household))).
The interpolated persons per household ratio for 2021 based on the SANDAG data would be
3.221. Using the 2021 persons per household ratio of 3.221, as calculated above, and the 170
residential units, the estimated residential population of the Project would be 547.57, rounded to
548 residents. Since the project would not have employees, the 548 residents accounts for the SP.
3.5 Impact Analysis
3.5.1 Would the project generate greenhouse gas emissions, either directly or
indirectly, that may have a significant impact on the environment?
Construction Emissions
Construction of the Project would result in GHG emissions, which are primarily associated with
use of off-road construction equipment, on-road hauling and vendor (material delivery) trucks,
and worker vehicles. GHG emissions associated with temporary construction activity were
quantified using CalEEMod. A detailed depiction of the construction schedule—including
information regarding phasing, equipment utilized during each phase, haul trucks, vendor trucks,
and worker vehicles—is included in Section 2.4.2.1 of this report.
Table 18 shows the estimated annual GHG construction emissions associated with the Project, as
well as the amortized construction emissions over a 30-year “project life.”

Notes: CO2 = carbon dioxide; CH4 = methane; N2O = nitrous oxide; CO2E = carbon dioxide equivalent.
See Appendix A for complete results.
Total construction emissions for the Project were 437 MT CO2E. Estimated amortized Project-
generated construction emissions would be approximately 15 MT CO2E. However, because there
is no separate GHG threshold for construction emissions alone, the evaluation of significance is
discussed in the operational emissions analysis below.
Operational Emissions
Operation of the Project would generate GHG emissions through motor vehicle trips to and from
the Project site; landscape maintenance equipment operation; energy use (natural gas and
generation of electricity consumed by the Project); solid waste disposal; and generation of
electricity associated with water supply, treatment, and distribution and wastewater treatment.
CalEEMod was used to calculate the annual GHG emissions based on the operational
assumptions described in Section 3.4.2.2, Operation.
The estimated operational (year 2021) Project-generated GHG emissions from area sources,
energy usage, mot or vehicles, solid waste generation, and water usage and wastewater
generation are shown in Table 19.

See Appendix A for detailed results.
These emissions reflect California Emissions Estimator Model “mitigated” output and operational year 2021.
As shown in Table 19, estimated annual Project-generated GHG emissions in 2021 would be
approximately 915 MT CO2E per year as a result of Project operations. Estimated annual
Project-generated emissions in 2021 from area, energy, mobile, solid waste, and
water/wastewater sources and amortized Project construction emissions would be approximately
930 MT CO2E per year.
City-Specific Efficiency Metric
As discussed in Section 3.4.1, a quantitative analysis using a City-specific efficiency metric
threshold for a post-2020 year (i.e., 2021) was developed. The efficiency metric calculated for
2021 (as shown in Section 3.4.1, Significance Criteria) is 1.78 MT CO2E per SP.
As discussed in Section 3.4.2.2, the P roject is anticipated to generate 548 residents. Using the
estimated operational emissions of 930 MT CO2E and service population of 548, the Project
would have a GHG efficiency metric of 1.70 MT CO2E per SP. The Project’s efficiency metric
would not exceed the significance threshold efficiency metric of 1.78 MT CO2E per SP.
Therefore, the Project would be considered to have a less-than-significant impact with respect
to GHG emissions without mitigation.
Mitigation
No mitigation is required.
Level of Significance After Mitigation
The Project’s impact would be less than significant prior to mitigation.
3.5.2 Would the project conflict with an applicable plan, policy, or regulation
adopted for the purpose of reducing the emissions of greenhouse gases?
This section discusses the Project’s consistency with the City’s CAP, SANDAG’s Regional Plan,
and CARB’s Scoping Plan.

As shown in Table 21, the Project is consistent with all applicable Regional Plan Policy
Objectives or Strategies. SANDAG worked with the local jurisdictions to identify Regional
Housing Needs Assessment allocation options that meet the four goals of housing element law
(Government Code Section 65484(d)(1)-(4)) within the Regional Plan. The second of the four
objectives of the SANDAG Regional Housing Needs Assessment is to promote infill
development and socioeconomic equity, the protection of environmental and agricultural
resources, and the encouragement of efficient development patterns. Also, one of the key
achievements project ed for the Regional Plan is for nearly three -quarters of multi-family
housing to be built on redevelopment or infill sites. This Project would be consistent with that
goal as it is developing on an infill site.

In summary, the Project promotes a pedestrian experience for the Project’s residents and visitors
that facilitates non-vehicular travel, consistent with SB 375 and SANDAG’s Regional Plan. As
shown in Table 21, the Project would be consistent with policy objectives of SANDAG’s
Regional Plan. Impacts would be less than significant.
Consistency with CARB’s Scoping Plan
The Scoping Plan, approved by CARB on December 12, 2008, provides a framework for
actions to reduce California’s GHG emissions and requires CARB and other state agencies to
adopt regulations and other initiatives to reduce GHGs. As such, the Scoping Plan is not
directly applicable to specific projects. Related ly, in the Final Statement of Reasons for the
Amendments to the CEQA Guidelines, the CNRA observed that “[t]he [Scoping Plan] may not
be appropriate for use in determining the significance of individual projects because it is
conceptual at this stage and r elies on the future development of regulations to implement the
strategies identified in the Scoping Plan” (CNRA 2009 a). Under the Scoping Plan, however,
there are several state regulatory measures aimed at the identification and reduction of GHG
emissions. CARB and other state agencies have adopted many of the measures identified in the
Scoping Plan. Most of these measures focus on area source emissions (e.g., energy usage,
high-GWP GHGs in consumer products) and changes to the vehicle fleet (i.e., hybrid, electric,
and more fuel-efficient vehicles) and associated fuels (e.g., low-carbon fuel standard), among
others. The Project would comply with all applicable regulations adopted in furtherance of the
Scoping Plan to the extent required by law.
The Scoping Plan recommends strategies for implementation at the statewide level to meet the
goals of AB 32 and establishes an overall framework for the measures that will be adopted to
reduce California’s GHG emissions. Table 22 highlights measures that have been developed
under the Scoping Plan and the Project’s consistency with Scoping Plan measures. The table also
includes measures in the 2017 Scoping Plan Update. To the extent that these regulations are
applicable to the Project, its inhabitants, or uses, the Project would comply with all applicable
regulations adopted in furtherance of the Scoping Plan.

In addition to the measures outlined in the table above, the Scoping Plan also highlights , in
several areas, the goals and importance of infill projects. Specifically, the Scoping Plan calls out
an ongoing and proposed measure to streamline CEQA compliance and other barriers to infill
development. The plan encourages infill projects and sees them as crucial to achieving the
State’s long-term climate goals. The plan encourages accelerating equitable and affordable infill
development through enhanced financing and policy incentives and mechanisms.
The State will complete an Integrated Natural and Working Lands Climate Change Action Plan
by 2018, which will consider aggregation of eco-regional plans and efforts to achieve net
sequestration goals. The Action Plan will include goals and plans to promote and provide
incentives for infill development through community revitalization and urban greening and
promote the adoption of regional transportation and development plans, such as SB 375
Sustainable Communities Strategies and Climate Action Plans, that prioritize infill and compact
development and also consider the climate change impacts of land use and management.
The following strategies were outlined as to expand infill development within the scoping plan:
Encouraging regional Transfer of Development Rights programs to allow owners of
natural and working lands to sell their development rights to developers who can use
those rights to add additional density to development projects in preferred infill areas.
Promoting regional Transit-Oriented Development funds that leverage public resources with
private-sector investment capital to provide flexible capital for Transit-Oriented
Development projects.
Rebates for low-VMT/location-efficient housing, similar to programs that use rebates to
encourage adoption of energy-efficient appliances, ZEVs, water-efficient yards, or
renewable energy installation. For example, the rebate could reimburse residents for a
portion of the down payment for purchasing or renting a qualified home in exchange for a
minimum term of residence.
Promotion of cross-subsidizing multi-station financing districts along transit corridors to
leverage revenues from development in strong-market station areas in order to seed
needed infrastructure and development in weaker-market station areas.
Abatement of residential property tax increases in exchange for property-based
improvements in distressed infill areas.
Ways to promote reduced parking in areas where viable transportation alternatives are present.
Additional creative financing mechanisms to enhance the viability of priority infill projects.

Ways to promote and strengthen Urban Growth Boundaries to promote infill
development and conservation of natural and working lands by defining and limiting
developable land within a metropolitan area according to projected growth needs.
In summary, the Project would be consistent with the measures and policy goals as shown in Table 22.
The Project would also be consistent with the various efforts the Scoping Plan established to encourage
infill development projects. Therefore, the Project would be consistent with CARB’s Scoping Plan.
Finally, the SDAPCD has not adopted GHG reduction measures that would apply to the GHG
emissions associated with the Project. Therefore, this impact would be less than significant.
Mitigation Measures
No mitigation is required.
Level of Significance After Mitigation
The Project’s impact would be less than significant prior to mitigation.

SUMMARY
The purpose of this health risk assessment (HRA) is to determine the potential cancer risk of the
future residents for the proposed Bonita Glen Project (Project) due to emissions resulting from
vehicles traveling on the adjacent Interstate (I-) 805 in accordance with Policy EE 6.10 of the
City of Chula Vista’s General Plan.
Dispersion modeling was conducted using the American Meteorological Society/Environmental
Protection Agency Regulatory Model (AERMOD). The San Diego Air Pollution Control
District’s (SDAPCD’s) Supplemental Guidelines for Submission of Air Toxics “Hot Spots”
Program Health Risk Assessments , the Sacramento Metropolitan Air Quality Management
District’s Recommended Protocol for Evaluating the Location of Sensitive Land Uses
Adjacent to Major Roadwa ys, the U.S. Environmental Protection Agency’s Transportation
Conformity Guidance for Quantitative Hot -spot Analyses in PM2.5 and PM10 Nonattainment
and Maintenance Areas , and the Office of Environmental Health Hazard Assessment’s
(OEHHA) Air Toxics Hot Spots Program Risk Assessment Guidelines Guidance Manual for
Preparation of Health Risk Assessments (2015 Risk Assessment Guidelines Manual; OEHHA
2015) were used to prepare this HRA. According to the OEHHA, HRAs should be based on a 9,
30, and 70-year exposure duration. Although the SDAPCD Guidance is specifically targeted
towards health risk from air toxic emissions from stationary source operations, the thresholds
were adapted here for informational purposes.
This HRA finds that the maximally exposed individual resident of the Project would be exposed
to a cancer risk of greater than the SDAPCD’s threshold of 10 in 1 million prior to mitigation and
would result in a potentially significant impact. With mitigation, the cancer risk would be reduced
to below levels of significance. Therefore, the impact would be less than significant with
mitigation.

1 INTRODUCTION
1.1 Purpose
In support of the air quality technical report preparation, Dudek has prepared a health risk
assessment (HRA) modeling analysis to estimate health risk impacts on future residents from
exposure to vehicle emissions from I-805. This assessment was prepared in accordance with
the City of Chula Vista’s (City) General Plan Policy EE 6.10.
The analysis in this HRA uses air dispersion modeling methodology to evaluate potential public
health risks from roadway emissions adjacent to the Project. Results of the modeling analysis are
compared with the most recent California Environmental Quality Act (CEQA) significance
thresholds established by SDAPCD.
Per CEQA Guidelines, Appendix G (14 CCR 15000 et seq.), the HRA directly addresses question
(d): Would the project expose sensitive receptors to substantial pollutant concentrations?
1.2 Project Description
The Project is a 170-unit apartment development on a previously undeveloped 5.3-acre site
located in the City, California. The site is located within the Bonita Glen Specific Plan Area just
west of I-805 and South of E Street and is shown on Figure 1. The Project includes the
development of 170 apartment units within 6 three-story, garden-style buildings (2 twenty-one-
plex buildings, 2 eighteen-plex buildings, and 2 thirteen-plex buildings) and 1 four-story,
podium-style building (66 units). Total building area for the Project is approximately 165,000
square feet. The proposed 170 units would be spread across 5 separate, contiguous parcels,
Assessor Parcel Numbers 570-131-11-00, 570-140-40-00, 570-140-54-00, 570-140-48-00, and
570-140-51-00, at a proposed density of 32 units/acre. The Project includes covered (124 spaces)
and uncovered (98 spaces) parking and recreation areas, including a swimming pool, clubhouse,
and dog park. The Project provides 17 affordable dwelling units (10%) restricted for 55 years to
lower income households (80% of the area median income) in a recorded restrictive covenant.
The Project location is provided on Figure 1.
1.3 Toxic Air Contaminants
A substance is considered toxic if it has the potential to cause adverse health effects in humans,
including increasing the risk of cancer upon exposure or acute (short-term) and/or chronic (long-
term) non-cancer health effects. A toxic substance released into the air is considered a toxic air
contaminant (TAC). Examples include certain aromatic and chlorinated hydrocarbons, DPM,
certain metals, and asbestos. TACs are generated by a number of sources, incl uding stationary
sources such as dry cleaners, gas stations, combustion sources, and laboratories; mobile sources,

10271

such as automobiles; and area sources, such as landfills. Adverse health effects associated with
exposure to TACs may include carcinogenic (i.e., cancer-causing) and noncarcinogenic effects.
Noncarcinogenic effects typically affect one or more target organ systems and may be
experienced through either acute or chronic exposure to a given TAC.
California’s air toxics control program began in 1983 with the passage of Assembly Bill 1807,
the Toxic Air Contaminant Identification and Control Act, better known as the Tanner Bill. The
Tanner Bill established a regulatory process for the scientific and public review of individual
toxic compounds. When a compound becomes listed as a TAC under the Tanner Bill, the
California Air Resources Board (CARB) normally establishes minimum statewide emission-
control measures to be adopted by air quality management districts and air pollution control
districts. By 1992, 18 of the 189 federal hazardous air pollutants had been listed by CARB as
state TACs. In April 1993, CARB added 171 substances to the state program to make the state
TAC list equal to the federal list of hazardous air pollutants. In 1998, CARB designated DPM as
a TAC (CARB 1998). The exhaust from diesel engines is a complex mixture of gases, vapors,
and particles, many of which are known human carcinogens. DPM has established cancer risk
factors and relative exposure values for long-term chronic health hazard impacts. No short-term,
acute relative exposure values are established for DPM; therefore, acute impacts of DPM are not
addressed in this HRA.
The second major component of California’s air toxics program, supplementing the Tanner
process, was provided by the passage of Assembly Bill 2588, the Air Toxics “Hot Spots”
Information and Assessment Act of 1987. Assembly Bill 2588 currently regulates over 600
compounds, including all of the Tanner Bill–designated TACs.
Additionally, Proposition 65, passed by California voters in 1986, requires that a list of
carcinogenic and reproductive toxicants found in the environment be compiled; the discharge of
these toxicants into drinking water be prohibited; and warnings of public exposure by air, land,
or water be posted if a significant adverse public health risk is posed. The emission of any listed
substances by a facility would require a public warning unless health risks could be demonstrated
to be less than significant. For carcinogens, Proposition 65 defines the “no significant risk level”
as the level of exposure that would result in an increased cancer risk of greater than 1 in 100,000
over a 70-year lifetime (27 CCR 25711). The “no significant risk level” is 1 in 1,000 of the “no
observable effect level” for reproductive toxicants.

In 2000, CARB approved a comprehensive Diesel Risk Reduction Plan to reduce diesel
emissions from new and existing diesel-fueled vehicles and engines. The regulation is
anticipated to result in an 80% decrease in statewide diesel health risk in 2020 compared with the
diesel risk in 2000. Additional regulations apply to new trucks and diesel fuel, including the On-
Road Heavy-Duty Diesel Vehicle (In-Use) Regulation, On-Road Heavy-Duty (New) Vehicle
Program, In-Use Off-Road Diesel Vehicle Regulation, and New Off-Road Compression-Ignition
(Diesel) Engines and Equipment program. These regulations and programs have timetables by
which manufacturers must comply and existing operators must upgrade their diesel-powered
equipment. Several Airborne Toxic Control Measures reduce diesel emissions, including In-Use
Off-Road Diesel-Fueled Fleets (13 CCR 2449 et seq.) and In-Use On-Road Diesel-Fueled
Vehicles (13 CCR 2025).
1.4 Cancer Risk
Cancer risk is defined as the increase in lifetime probability (chance) of an individual developing
cancer due to exposure to a carcinogenic compound, typically expressed as the increased
probability in 1 million. The cancer risk from inhalation of a TAC is estimated by calculating the
inhalation (and if applicable, ingestion) dose in units of milligrams/kilogram body weight per
day based on an ambient concentration in units of micrograms per cubic meter (μg/m3), breathing
rate, and exposure period and multiplying the dose by the inhalation cancer potency factor,
expressed as (milligrams/kilogram body weight per day)-1. Cancer risks are typically calculated
for all carcinogenic TACs and summed to calculate the overall increase in cancer risk to an
individual. The calculation procedure assumes that cancer risk is proportional to concentrations
at any level of exposure and that risks due to different carcinogens are additive. This approach is
generally considered a conservative assumption at low doses and is consistent with the current
OEHHA regulatory approach. Exposure to carcinogenic TACs does not imply that the exposed
individual would contract cancer; rather, the cancer risk is a probability of developing cancer if
other factors (e.g., heredity, exposure to environmental or workplace risks that compromise the
immune system, overall health) would result in an increased susceptibility to developing cancer.
The cancer risk calculations were performed by multiplying the predicted dispersion modeled
output data by the TAC emissions and the appropriate risk values. The exposure and risk
equations that were used to calculate the cancer risk at receptors are integrated in the Hotspots
Analysis and Reporting Program, Version 2 (HARP 2) (CARB 2015a), model in accordance
with the 2015 Risk Assessment Guidelines Manual (OEHHA 2015).
The following equations were used to calculate the cancer risk using the model output data and
estimated TAC emissions associated with diesel exhaust.
Health Risk Assessment for the Bonita Glen Project
10271
6 October 2018
Cancer risk = DOSE * CPF * ASF * ED/AT * FAH
DOSE = (Cair * DBR * A * EF * 10-6)
Cair= ER * X/Q
Where:
DOSE: Daily inhalation dose (mg/kg-day)
CPF: Cancer potency factor (mg/kg-day)-1
ASF: Age sensitivity factor for a specified age group (unitless)
ED: Exposure duration (in years) for a specified age group
AT: Averaging time for lifetime cancer risk (years)
FAH: Fraction of time spent at home (unitless)
Cair: Average air concentration of TAC from the air dispersion model (μg/m3)
DBR: Daily breathing rate (L/kg body weight-day)
EF: Exposure frequency (unitless), days/365 days
A: Inhalation absorption factor (unitless)
10-6: Micrograms to milligrams conversion, liters to cubic meters conversion
ER: Emission rates (grams/second)
X/Q: Model output data (μg/m3)/(grams/second)
1.5 Non-Cancer Health Impacts
The non-cancer health impact of an inhaled TAC is measured by the hazard quotient, which is
the ratio of the ambient concentration of a TAC in units of μg/m 3 divided by the reference
exposure level (REL), also in units of μg/m3. The REL is the concentration at or below which no
adverse health effects are anticipated. The REL is typically based on health effects on a
particular target organ system, such as the respiratory system, liver, or central nervous system.
Hazard quotients of individual TACs are then summed for each target organ system to obtain a
hazard index. For DPM, the target organ system is the respiratory system.
In addition to the potential cancer risk, DPM has chronic (i.e., long-term) non-cancer health
impacts. The chronic hazard index (HIC) for DPM was calculated by dividing the maximum
modeled annual average concentration of TACs by its REL as implemented by HARP 2.
Health Risk Assessment for the Bonita Glen Project
10271

The chronic hazard quotients were calculated for DPM using the following equations
(OEHHA 2015).
HIC = (Cair /REL)
Where:
HIC: Chronic hazard index
Cair: Annual average concentration (μg/m3)
REL: Chronic reference exposure level (μg/m3)

2 GUIDANCE AND THRESHOLDS
2.1 Office of Environmental Health Hazard Assessment’s Guidance
OEHHA’s most recent guidance is the 2015 Risk Assessment Guidelines Manual (OEHHA
2015), which was adopted in 2015 to replace the 2003 HRA Guidance Manual. The Children’s
Environmental Health Protection Act of 1999 (Senate Bill 25), which requires explicit
consideration of infants and children in assessing risks from air toxics, requires revisions of the
methods for both non-cancer and cancer risk assessment and of the exposure assumptions in the
2003 HRA Guidance Manual. In response to Senate Bill 25, OEHHA released three technical
support documents addressing RELs (OEHHA 2008), cancer potency (OEHHA 2009), and
exposure assessment and stochastic analysis (OEHHA 2012) and adopted the 2015 Risk
Assessment Guidelines Manual (OEHHA 2015). The technical support document for RELs and
continuing work to re-evaluate TACs to ensure adequate protection for infants and children has
led to revisions of RELs for approximately 10 chemicals and chemical families. The basic
methodology for evaluating acute and chronic health effects using the RELs otherwise remained
the same as in the previous guidance manual. Moreover, RELs are designed to protect the most
sensitive individuals in the population, including infants and children, by selecting appropriate
toxicological data and including margins of safety. Accordingly, the evaluation methods are
assumed to protect children and other sensitive subpopulations (groups of more highly
susceptible individuals) from adverse health effects in the event of exposure (OEHHA 2008).
The cancer risk methodology described in the exposure assessment and stochastic analysis
technical support document and the 2015 Risk Assessment Guidelines Manual accounts for the
higher sensitivity of infants and children by applying age -specific daily breathing rates and
age-sensitivity factors. According to the technical support document, “accounting for effects of
early-in life exposure requires accounting for both the increased potency of early in life
exposure to carcinogens and the greater ex posure on a per [kilogram] body weight that occurs
early in life due to behavioral and physiological differences between infants and children, and
adults” (OEHHA 2012). In part, early-life periods are accounted for through the use of age-
sensitivity factor s. Compared to the previous guidance, which relied on a single breathing rate
for all ages, the revised guidance includes age -specific daily breathing rates that reflect the
differences for infants, children, and adults. Th is HRA uses HARP 2, which incorpo rates RELs
and cancer potency factors, which are periodically updated, and health effects calculations
based on the 2015 Risk Assessment Guidelines Manual. Accordingly, this HRA evaluates and
reflects conservative, health-protective methodologies to assess health impacts to adults , as
well as infants, children, and other sensitive subpopulations.

2.2 San Diego Air Pollution Control District Guidance
The SDAPCD’s Supplemental Guidelines for Submission of Air Toxics “Hot Spots” Program
Health Risk Assessments (SDAPCD 2015) provides guidance to perform HRAs within the San
Diego Air Basin. These supplemental guidelines address the modelling specific and user default
options for the risk evaluation incorporated into the HARP developed by the CARB, OEHHA,
and the Districts, which is the recommended program to use for Air Toxics “Hot Spots” HRAs.
The SDAPCD’s current thresholds of significance for TAC emissions from the operations of
permitted and non-permitted sources are combined and presented in Table 1.

2.3 Sacramento Metropolitan Air Quality Management
District Guidance
The Sacramento Metropolitan Air Quality Management District’s Recommended Protocol for
Evaluation the Location of Sensitive Land Uses Adjacent to Major Roadways (Protocol;
SMAQMD 2011) provides a methodology for the assessment and disclosure of potential cancer
risk from DPM attributable to siting sensitive land uses adjacent to freeways and major
roadways. This guidance builds on the CARB 2005 Land Use and Air Quality Handbook: A
Community Health Perspective. The Protocol defines a stepwise process that indicates the need
for and methodology to conduct a site-specific HRA. Of particular note, the Protocol
recommends a screening threshold of 100,000 vehicles per day for high traffic volume roadways.
The Protocol also recommends that the length of the roadway should be at least 10,000 feet
(5,000 feet for each link) to ensure pollutant capture (SMAQMD 2011).
2.4 U.S. Environmental Protection Agency Guidance
The U.S. Environmental Protection Agency offers guidance for roadway HRAs within its
Transportation Conformity Guidance for Quantitative Hot-Spot Analyses in PM2.5 and PM10
Nonattainment and Maintenance Areas (EPA 2015). More specifically, the guidance provides
specific references for HRA guidance, examples of projects, hot-spot analyses requirements,
examples of characterizing intersection projects for Motor Vehicle Emission Simulator,
examples of using EMFAC2011, estimates of locomotive emissions, and estimates of design

value calculations. The guidance also provides specific parameters for calculating the AERMOD
release height above the ground for a roadway HRA, which are 12 feet per lane for the width of
the traveled way and 1.7 times the average vehicle height for the initial vertical dimensions. The
guidance assumes that light-duty vehicles have an average height of 1.53 meters, and heavy-duty
vehicles have an average height of 4 meters. The release height can be weighted based on the
fleet composition (EPA 2015).

3 EMISSION CALCULATIONS
Traffic volumes were obtained to estimate emissions from diesel vehicle traffic traveling on I-
805. California Department of Transportation (Caltrans) data includes a breakdown of vehicle
volumes at the intersection of Bonita Road and I-805 adjacent to the Project site. These volumes
were used in this HRA to provide a conservative estimate of impacts at the Project site. Based on
the 2015 traffic volumes on the California state highways (Caltrans 2015), it was estimated that
the back annual average daily traffic (AADT) would be 220,000 and the ahead AADT would be
238,000 for an average AADT of 229,000. Back AADT represents traffic just south of the
intersection, while ahead AADT represents traffic just north of the intersection.
Data were obtained from the San Diego Association of Governments Series 13 forecast to
determine the projected growth in AADT at the intersection of Bonita Road and I-805
(SANDAG 2013). It was determined that the average annual growth rate in AADT from 2012 to
2050 was 0.02% per year. This factor was applied to the 2015 AADT to get a projected AADT
of 242,638 through 2091.
As explained previously, the primary TAC associated with high-volume roadways such as I-805
is DPM. Caltrans developed the CT-EMFAC2014 in collaboration with CARB to take into
account the latest vehicle fleet emissions for the state. The CT-EMFAC2014 was used to develop
TAC emission factors and emissions for the freeway segment for the analysis. Emissions were
generated in intervals of 5 years from 2021 through 2050. The first year of each five year period
was used as a conservative representation of the emissions within that five year period. The
Caltrans data showed that six percent of vehicle trips over the project segment were attributed to
trucks. The EMFAC2014 was used to estimate the vehicle miles travelled percentage by speed
bin. This data along with the speed composition data were entered into CT-EMFAC2014 to
develop the TAC emissions for the assessment. The CT-EMFAC2014 further decomposes the
vehicle fleet into Truck 1 and 2, which the default was assumed to be 1.4% and 4.6%
respectively. The CT-EMFAC2014 default percent of diesel and gasoline vehicles was assumed.
For this analysis, San Diego County and calendar years 2021 through 2050 were selected, as
2050 is the highest year CT-EMFAC2014 would estimate. Because this assessment evaluates up
to 70 years of exposure and data from CT-EMFAC2014 were not available beyond 2050, the
data for year 2050 were assumed for year 2051 through 2091.
Vehicle miles traveled were calculated by taking the AADT and multiplying it by the distance of
the freeway segment evaluated, which was 3,000 meters (1.86 miles), consistent with
Sacramento Metropolitan Air Quality Management District’s guidance (SMAQMD 2011).
Because the AADT represents total vehicle traffic flowing both south and north, the estimated
emissions were portioned out to the northbound and southbound directions according to the San

4 MODELING METHODOLOGY
4.1 Dispersion Model
Dudek conducted a dispersion modeling analysis of emissions from vehicles along a 3,000-meter
link of I-805 adjacent to the Project site for the HRA. The dispersion modeling was performed
using AERMOD View Version 9.6.1, which is the model SDAPCD recommends for
atmospheric dispersion of emissions. AERMOD is a steady-state Gaussian plume model that
incorporates air dispersion based on planetary boundary layer turbulence structure and scaling
concepts, including treatment of surface and elevated sources, building downwash, and simple
and complex terrain (EPA 2017).
Dudek evaluated the potential cancer and non -cancer health impacts from I-805 on future
residents using exposure periods appropriate to evaluate these emission increases. Dispersion
of emissions was modeled using AERMOD, and then cancer risk and non-cancer health impacts
subsequently using the HARP 2, which implements the 2015 OEHHA age-weighting
methodology for assessing TAC risks. The health risk results were then compared to SDAPCD
thresholds to assess Project significance.
The HRA was performed as a precautionary measure to evaluate any risk to nearby sensitive
receptors. Principal parameters of AERMOD for the Project operations included the following:
Meteorological Data: The latest 3-year meteorological data (2010–2012) for the Chula Vista
station from SDAPCD were downloaded, and then input to AERMOD (Gould pers. comm.
2017). For cancer or chronic non-cancer risk assessments, the average cancer risk of all years
modeled was used. A wind rose is provided for this station on Figure 2.
Urban and Rural Options: Typically, urban areas have more surface roughness and
structures and low-albedo surfaces that absorb more sunlight, and thus, more heat,
relative to rural areas. However, according to SDAPCD guidelines, the rural dispersion
option was selected due to the Project’s proximity to the ocean.
Terrain Characteristics: The terrain in the vicinity of the modeled Project site is
generally flat. The elevation of the modeled site is approximately 29 meters above sea
level. Digital elevation model files were imported into AERMOD so that complex terrain
features were evaluated as appropriate.
Discrete Receptors: A uniform Cartesian grid was placed over the Project site with 20-
meter spacing and converted into discrete receptors to represent future residents’ on site.
Source Equipment Operating Scenarios: Air dispersion modeling of I-805 was
conducted using emissions generated using California Department of Transportation data
and emission factors from CT-EMFAC2014, conservatively assuming the emissions
Health Risk Assessment for the Bonita Glen Project
10271

would occur 24 hours per day, 365 days per year, for 9, 30, and 70 years. I-805 was
modeled as two line volume sources, with one source representing southbound traffic and
one representing northbound traffic.
Source Release Characterizations: For modeling operational emissions dispersion
using AERMOD, it was assumed that the total site area would be exposed over a 9-, 30-,
and 70-year period. Table 2 shows the vehicle release characteristics used in the
AERMOD model.

Emission rate grams per second 1
Release height meters 5
Plume height and width meters 25
Note: The release height and plume height were calculated based on the weighted average of the fleet of diesel vehicles based on California
Department of Transportation and San Diego Association of Governments data.
4.2 Health Risk Assessment Methodology
In March 2015, the OEHHA approved the new 2015 Risk Assessment Guidelines Manual
(OEHHA 2015). The SDAPCD requires that all HRAs prepared for CEQA documents follow
SDAPCD policies in conjunction with the 2015 Risk Assessment Guidelines Manual. To
implement the OEHHA guidance based on Project information, the SDAPCD has developed a
three-tiered approach where each successive tier is progressively more refined with each
progressive level being less conservative. SDAPCD’s Tier 1 approach is a screening assessment
methodology that incorporates very conservative assumption methodologies when specific
information about a project and its impact locations to actual or assumed receptor locations are
unknown. The Tier 2 approach provides a more accurate analysis since it requires specific
modeling input for project sources and proximate receptors that refine the Tier 1 approach.
Tier 2 cancer and non-cancer health risk calculations were performed for the Project using ground-
level unity emission concentration (X/Q) input from AERMOD. This modeling established the
emissions dispersion field to the proposed residential receptors from atmospheric influence of the
I-805 emissions. Plot files generated in AERMOD were then imported into HARP 2, with ground
level concentrations (GLC) determined by multiplication of annual average emission rates and
annually averaged X/Q values for the freeway line sources of emissions. HARP 2 then assessed
resulting cancer and non-cancer risk from operational TAC emissions.

5 RECEPTORS USED FOR EVALUATING MODELED IMPACTS
Some land uses are considered more sensitive to changes in air quality than others, depending on
the population groups and the activities involved. People most likely to be affected by air
pollution include children, the elderly, athletes, and people with cardiovascular and chronic
respiratory diseases. Facilities and structures where these air pollution-sensitive people live or
spend considerable amounts of time are known as sensitive receptors. Land uses where air-
pollution-sensitive individuals are most likely to spend time include schools and schoolyards,
parks and playgrounds, daycare centers, nursing homes, hospitals, and residential communities
(sensitive sites or sensitive land uses) (CARB 2005). The SDAPCD considers schools
(kindergarten through grade 12), daycare centers, nursing homes, retirement homes, health
clinics, and hospitals within 2 kilometers of the facility as sensitive receptor land uses (SDAPCD
2015). As previously discussed, this HRA evaluates the risk to future residents of the Proje ct.

6 AIR DISPERSION MODELING HRA RESULTS
6.1 Health Risk Assessment Results
The maximally exposed individual resident would be at the northeastern corner of the Project
site. The results represent a worst-case conservative assumption of an on-site resident outside 24
hours per day, 365 days per year, for the 9-, 30-, and 70-year exposure durations and are shown
in Table 3.

Notes: HIC = Chronic Hazard Index.
The results of the HRA demonstrate that the exhaust emissions from the I-805 exhibit cancer
risks above the 10 in 1 million threshold and chronic hazard index less than 1. As shown in
Figure 3, all receptors onsite showed cancer risk above the threshold level in the 9-, 30-, and 70-
year exposure scenarios. AERMOD and HARP 2 outputs are contained in Appendix B.
Therefore, the project may result in a potentially significant impact. As such, mitigation is
required.

6.2 Mitigation Measures
Consistent with SDAPCD guidance, mitigation measures were evaluated to identify ways to
ensure that residents of the proposed project would not be exposed to health risks that exceed
SDAPCD’s significance thresholds and to ensure that impacts related to community risk and
hazards from placement of sensitive receptors proximate to major sources of air pollution would
be less than significant.
The US EPA reported that the Minimum Efficiency Reporting Value (MERV) 13 filters remove
90% of particles ranging from 1 to 10 microns (EPA 2018). For this analysis, Dudek assumed an
90% particulate matter reduction for the air filters. No reduction in pollutant concentrations due
to the use of filters was applied to gaseous TACs such as benzene, toluene, and formaldehyde.
The National Human Activity Pattern Survey (NHAPS) was conducted in support by the US
EPA to study where people spend their time. The results of the NHAPS showed that on average
people spend 87% of their time in enclosed buildings and 6% of their time in enclosed vehicles
(Kleipeis et. al. 2001). This assessment of risk with mitigation includes the accounting for time
spent indoors as identified in the NHAPS and the time spent away from home as recommended
by OEHHA (OEHHA 2015). Accounting for the actual time spent indoors and exposure related
to the residents within the project provides a more realistic exposure scenario from TAC
emissions from the 805 freeway.
Studies have shown that vegetative landscaping can reduce particulate emissions by up to 65% to
85% at lower wind speeds, with greater removal rates expected for ultra-fine particles < 0.1 μm
in diameter. The effectiveness of PM removal via tree plantings depends on characteristics of the
species chosen (e.g., foliage surface, canopy structure, and life span) and varies by particulate
size (Fujii et al. 2008, Miller et al. 2009, SMAQMD 2011). Mitigation measure MM-HR-4 has
been provided to further reduce impacts related to particulates; however, emission reductions
from installation of tiered vegetative landscaping as described in MM-HR-4 was not quantified
for the purposes of impact determination because MM-HR-1 through MM-HR-3 mitigate
impacts to particulate exposure to a level that is less than significant.
The following mitigation measures would reduce the significant impacts associated with cancer
risk levels below the SDAPCD thresholds:
MM-HR-1 The applicant or its successor shall install high-efficiency return air filters on all
heating, ventilation, and air conditioning (HVAC) systems serving the project.
The air filtration system shall reduce at least 90% of particulate matter emissions,
such as can be achieved with a Minimum Efficiency Reporting Value 13 (MERV
13) air filtration system installed on return vents in residential units. The property
Health Risk Assessment for the Bonita Glen Project
10271

management for the project shall maintain the air filtration system on any HVAC
system installed for the specified residential units in accordance with the
manufacturer’s recommendations for the life of the project.
MM-HR-2 The applicant or its successor shall locate air intake vents on the residential
buildings such that they do not face the 805 freeway and are as far from 805
freeway as practicable.
MM-HR-3 A City-approved, ASHRAE certified specialist shall verify the implementation of
the installation of high-efficiency air filtration systems on return vents to reduce
ambient particulate matter concentrations prior to occupancy of the residential
units. On-going maintenance of the installed filtration systems shall be the
responsibility of the applicant or its successor. The City may enforce that the
systems are in accordance with the manufacturer’s recommendations for the life of
the project.
MM-HR-4 As part of landscape design and vegetation palette for the project, installation of
tiered vegetative landscaping is encouraged, including the installation of
evergreen trees, between the 805 freeway and the project. Any vegetation selected
shall be compatible with the proposed project Fire Protection Plan. The tiered
vegetation shall be maintained as part of the residential community landscaping
areas where feasible.
Implementing Mitigation Measures MM-HR-1, MM-HR-2, and MM-HR-3 would reduce the
maximum cancer risks at the residential point of maximum impact. The results of the risk assessment
with mitigation are shown in Table 4.

The cancer and non-cancer results of the roadway HRA show that with mitigation the project
would not exceed the SDAPCD significance thresholds. Therefore, with respect to CEQA
Appendix G, air quality question (d), TAC emissions from the 805 freeway would not expose
sensitive receptors to substantial pollutant concentrations with mitigation.

7 CONCLUSIONS
Based on this analysis, the future residents of the Project would not be exposed to TACs at levels
above significance thresholds established by SDAPCD with implemented mitigation. The results
determined in this analysis reflect reasonable estimates of source emissions and exhaust
characteristics, available meteorological data near the Project site, and the use of currently
approved air quality models. Given the limits of available tools for such an analysis, the actual
impacts may vary from the estimates in this assessment. However, the combined use of the
AERMOD dispersion model and the health impact calculations required by OEHHA and
SDAPCD tend to over predict impacts such that they produce conservative (i.e., health-
protective) results. The emissions used in the analysis take into account all planned emissions
reductions and do not account for any future, but not adopted, regulations or rules reducing
emissions or changes in the vehicle fleets. Accordingly, the health impacts are not expected to be
higher than those estimated in this assessment.
