3.3 PROJECT PURPOSE AND OBJECTIVES The Otay Valley Quarry Reclamation Plan Amendment has been prepared by the project applicant in accordance with the requirements of SMARA found in PRC Section 2710 et seq., Tide 14 of the CCR Section 3500 et seq., and the City of Chula Vista's (the lead agency) implementing ordinance. SMARA's Reclamation Plan requirements are found primarily in PRC Section 2772 and in CCR Section 3502. Minimum standards to be followed (CCR Section 3503) and reclamation performance standards (CCR Section 3700 et seq.), as applicable to the operation and its approved plan, must be met during operations and reclamation. Based on SMARA, the proposed Reclamation Plan is intended to serve the following purposes: ~~~~~~ Provide the required contents for a Reclamation Plan as specified in PRC Section 2772 and CCR Section 3502; ~~~~~~ Serve as a reference manual for the mine operator to guide site reclamation consistent with the approved Reclamation Plan and to assist in regulatory compliance for operational activities; and ~~~~~~ Serve as a compliance document for the City of Chula Vista in monitoring ongoing compliance with the reclamation plan, as approved. As presented in the proposed Reclamation Plan Amendment and pursuant to CCR Section 3502(h)(1), the Reclamation Plan Amendment functions as an amendment to the Otay Ranch Pit Reclamation Plan Amendment approved by the State Mining and Geology Board on June 13, 2006, for the mining of a new surface area that is consistent with a vested mining rights determination made by the City of Chula Vista. The Reclamation Plan Amendment is intended to supersede provisions and requirements of all previous reclamation plans and amendments with respect to the Project Site. The Otay Valley Quarry Reclamation Plan Amendment is proposed to supersede provisions and requirements of all previous reclamation plans and amendments with respect to the Project Site as shown in Figure 3-1, Site Location -USES Map. As indicated in Section 3.2.2 of this EIR, certain portions of the Quarry Boundary are subject to provisions of the current Otay Ranch Pit Reclamation Plan Amendment. Specifically, these portions are known as the "North Parcel," the "West Parcel," and the "South Parcel;" the location of these parcels is illustrated in Figure 2-5 of this EIR. The North Parcel (10.4 acres) has substantially initiated reclamation activities, and future reclamation and revegetation of this parcel would comply with the Otay Ranch Pit Reclamation Plan Amendment, as well as additional requirements of the Otay Quarry MSCP Boundary Adjustment (Chula Vista Case Number PCM-10-14); however, the fill identified in the Otay Ranch Pit Reclamation Plan Amendment would no longer be placed on the North Parcel. More specifically, the 9.3-acre portion of the North Parcel subject to the MSCP Boundary Adjustment will be revegetated pursuant to the Boundary Adjustment document, while the portions of this parcel not covered under the Boundary Adjustment will be reclaimed and revegetated pursuant to the Otay Ranch Pit Reclamation Plan Amendment. (For a discussion of the approved Boundary Adjustment, see Section 2.5, below.) The proposed Otay Valley Quarry Reclamation Plan Amendment would be implemented at the Otay Valley Quarry when mining operations cease, which is estimated to be 2089. The Otay Valley Quarry is a hard rock quarry configured as an open pit, surrounded by stabilized land. Other than implementation of the Otay Valley Quarry Reclamation Plan Amendment Page 3-4 Environmental Impact Report (EIR) DRAFT: March 2011; FINAL: June 2011 ~~~~~~~ ~°~~" IIII'ilY~ ~~i~l~~~~ IIIIIIIIII ~' ~~~~~~~ IIIIIIIIIL`~~ ~' IIII'ilY~ 1111 IIII'~~~°~~"'I ~i~ll~ IIII~~~~l proposed Otay Valley Quarry Reclamation Plan Amendment, no other development is proposed as part of the project evaluated in this EIR. Therefore, the Otay Valley Quarry Reclamation Plan Amendment project would accomplish the following basic objectives of SMARA: ~~~~~~ Provide for long-term stability of slopes; ~~~~~ Prevent wind and water erosion by stabilizing the soil surface through proper grading and drainage; and ~~~~~~ Implement a revegetation program that is designed to establish self-sustaining native vegetation cover, until subsequent land development occurs. The proposed Reclamation Plan Amendment lays out these objectives specifically to meet physical reclamation treatment objectives for disturbed land in a manner that adheres to the applicable SMARA statutes, as listed below: ~~u~u PRC Section 2712(a). Adverse environmental effects are prevented or minimized and that mined lands are reclaimed to a usable condition which is readily adaptable for alternative land uses. ~~~~~~ PRC Section 2712(b). The production and conservation of minerals are encouraged, while giving consideration to values relating to recreation, watershed, wildlife, range and forage, and aesthetic enjoyment. ~~~~~~ PRC Section 2712(c). Residual hazards to the public health and safety are eliminated. SMARA requires a description of the "proposed or potential uses" of a mined site after reclamation. Section 19.69.080.B.5 of the City of Chula Vista's Zoning Code also requires that the Reclamation Plan "restore the mined lands to a useable condition that is readily adaptable for alternative land uses consistent with the general plan and multiple species conservation program." 3.4 PROJECT CHARACTERISTICS The proposed project evaluated in this EIR is a Reclamation Plan Amendment that would be implemented following completion of mining at the Otay Valley Quarry, anticipated to be about the year 2089. In order to understand how the Reclamation Plan Amendment would affect the topography existing at the time of its implementation, it is important to understand how the on-going mining operations will create the ultimate topography that will form the landform base for the Reclamation Plan Amendment. The reader is reminded that the current mining operations have vested rights, and approval of the Reclamation Plan Amendment does not affect these vested rights. Moreover, the continued mining operations do not require discretionary actions by the City. Therefore, this EIR does not address any aspects of the mining operations. This EIR does not address the specifics of how mining is accomplished, including types of equipment, quantity of material to be mined, etc., all of which is allowed to occur on the Project Site under the existing approved vested mining rights. 3.4.1 Mining and Resultant Mined Topography The proposed Otay Valley Quarry Reclamation Plan Amendment would be implemented at the Otay Valley Quarry, an open pit mine which will be actively mined until about 2089, at which time reclamation would begin. Mining at the site encompasses a mining operation eventually reaching approximately 197 acres of the 278-acre quarry. Actual active surface disturbance is kept to the minimum areas necessary for mining Otay Valley Quarry Reclamation Plan Amendment Page 3-5 Environmental Impact Report (EIR) DRAFT: March 2011; FINAL: June 2011 II ~ uu ~~ ~~~ ~~~~~ 9I ~~~ ~ ~ ~~~ ~~~~ and processing at an~~ given time. Figure 3-2, ~lliTae Gra~liT2~ Plaza, shows the results of the active minim; for the quarry. Figure 3-3, Mining and fxistin~ Surface Cross-Sections, depicts the ultimate result of mining and its changes to the current landform, and the Mine Phasing is shown in Figure 3-4. The current mining operation will ultimately excavate to depths that are below the local groundwater table, leaving a water feature at the end of mining and prior to reclamation. The quarry floor is planned for a maximum depth of approximately 300 feet below mean sea level, with a water surface anticipated at approximately 100 feet above mean sea level. The quarry high walls will be cut at a grade not to emceed 1:1 for a stable slope condition, except in the areas where benching will be eliminated to create sheer slopes. (See Figure 3-5, ~uarr~ 1xcavation Cut S'lo~e CoYn~onents and DiYnensions.) Final grading will he completed in such a manner that the slopes will convey the majority of all stormwater to the quarry. 3.5 PROPOSED RECLAMATION PLAN AMENDMENT 3.5.1 Overview The topography of the completed mining site will reflect a tti~pical hard rock quarry configured as an open pit. Final phases of mining will eliminate some of the horizontal benches tti~pical with hard rock mining and create areas of sheer slopes to better conform to surrounding native topography. This will allow implementation of the grading associated with the proposed Reclamation Plan Amendment, as shown in Figure 3-6, Proposed KeclaYnation Plan AYnendYnent Grading Plan. iVlined surfaces would be leveled and stabilized for erosion control. Cut surfaces would be completed to slope grades to ensure long-term stability. Figure 3-7, Mine KeclaYnation Surface Cross-Sections, provides cross-sectional representation of mine slopes following grading proposed as part of the Reclamation flan Amendment. Sediment basins and fines storage areas would be dewatered and revegetated with plant species suitable for erosion control. Grading would be completed in such a manner as to ensure proper surface drainage. Recoverable topsoil would be stockpiled for use on benches and quarry floor areas to be revegetated. The soil would be placed to enhance revegetation as surfaces are completed. Active revegetation, as proposed by' the Reclamation Plan Amendment, would occur along the quarr~~'s edges and outward-f king slopes, the larger quarr~~ benches, and the relatively level areas near the west and south boundaries. ti'egetation species mimes, as described below, are site-specific and chosen with the intent of stabilizing areas of fill and blending with the adjacent vegetation. The success of revegetation would be monitored after completion of final reclamation to ensure successful erosion control Figure 3-8, Conceptual Illustrative I~ ~- ; i~,~, provides an illustration of the Project Site when reclamation has been completed and fully established.

The sidewalls of the mined quarry comprise the nature Santiago Peak ~rolcanic material which would he graded in ~rarious configurations -stepped henches, steep faces, "rounded contours," and se~reral peak-saddle-peak formations - as part of the proposed Reclamation Plan Amendment. This ~rariation in topographic configuration would reduce the highly uniform and engineered appearance of the sidewalls, reduce the angled edges at the ~e~water hodv line, and help integrate the quarry edges with adjacent land. The reclaimed sidewalls (internal) would range in grade from 1:1 to nearly ~rertical. A~o~re the natural water line, areas of fill ha~re been proposed to ~rarv the topographic profile, restoring it to a more natural configuration (peak-saddle-peak) as was e~rident prior to mining. The outward-facing fill slopes would ~rary~ in grade from appro~imately~ 2:1 to 8:1, much like the surrounding topography, and present an undulating character along the southernmost edge nearest the Otav Ri~rer. The henches ha~re been reconfigured to mimic the natural contours of the ri~rer ~rallev edge. The reclaimed quarry's central depression would fill with water naturally and ha~re a water surface elegyration equalized with the local groundwater tahle at approximately 85 to 127 feet aho~re mean sea le~rel (11iVISI ). Final grading would he completed in a manner such that the slopes would con~rev the majority of all de~relopmental stormwater in drainage to the quarry. ~~ctive re~regetation would occur along the quarr~~'s edges and outward-f king slopes, the larger quarr~~ henches, and the relati~rely le~rel areas near the west and south houndaries. The revegetation is intended to stahilize areas of fill and hlend with the adjacent ~regetation. ti'egetation species mimes are tailored to their specific site location with the riparian species nearest the Otay~ Ri~rer, and mimed coastal sage scruh/grassland at higher elegyrations, where these plants grow among the ahundant Santiago Peak ~rolcanic outcrops of Rock iVlountain. In addition, re~regetation would ~risuallv screen parts of the quarry and add foreground interest when ~riewing the quarry from the two western henches at higher elegyrations. lluring the extended period of mineral extraction, the natural process of re~regetation in some areas will ha~re already commenced. The stepped ~rolcanic henches remaining within the quarry would not he acti~rely~ re~regetated, as this would not he necessary for stahilization and would accentuate the engineered faces of the quarry. 3.5.3 Backfilling, Regrading, Slope Sfabilify, and Reconfouring The proposed Otav Valley Quarr~~ Reclamation Plan Amendment estahlishes specific criteria and actions to properly hackfill, regrade, and ensure slope stahility and proper recontouring of the site. The specific actions listed in the plan support three goals: manage stockpiles to facilitate phased reclamation; fill slopes, stahility and conformity with surrounding topography or end use; and cut slope stahilitti~. (The creation of stockpiles onh~ occurs during acti~re mining; during reclamation, stockpiles are managed, as necessarti~.)

Additionally, the project includes enlarged "amenitti~ planting" areas just outside the northeast and southeast limits that would ~e enhanced with additional container stock to expedite large shrub/small tree coverage along those edges. I andscape and irrigation plans shall ~e prepared ~y~ a licensed landscape architect and approved ~y~ the Cite. Plant species to ~e used in re~regetation are common to the site and surrounding area; many have naturally re~regetated without assistance. Active resoiling would occur as reyegetation areas are completed. A locally supplied seed min with success guaranteed ~v the supplier would ~e used. Test plots would ~e used to confirm the recommended application rate and specific min. Species to ~e planted (see Tales 3-1 through 3-6, below) would consist of commercially ayaila~le erosion control and nature plants that have evidenced good success on disturbed soils, and are consistent with ~regetation used in the region for this purpose. The proposed Reclamation flan Amendment includes re~regetation with plant species that are commercially ayaila~le for erosion control, nature plants that have evidenced good success on disturbed soils, and plant species that are consistent with vegetation used in the region for this purpose. Tales 3-1 through 3-6 display the proposed re~regetation seed and container plant ("amenity") palettes for the various reyegetation areas from which species would ~e selected.

Following completion of mining operations, overburden and top soil would ~e placed on benches and within the quarry bottom. Seeding and planting would then occur to re~regetate the benches. Temporary access to the edge of the quarry bottom for revegetation efforts can occur along existing quarry benches, as fill of the quarry depression with water is not expected to reach equilibrium level for approximately ten years after the end of quarry operations. In general, non-irrigated re~regetation areas would ~e seeded in either fall or winter to the extent practical for hest germination results.

The lower benches and quarry bottom may ~e used for stockpiling of overburden during the mining period; this material would ~e recovered or merely bulldozed over the side for use in reclamation of the quarry floor. The rock comprising the benches and walls would ~e much more impervious to penetration of water and plant roots than even the present restrictive layers of highly weathered rock that underlie the existing soil profiles on the site. Therefore, the quarry walls would not ~e seeded or otherwise revegetated. The upland perimeter and fill areas would ~e fetter suited to revegetation due to the presence of the deeper soil.

Container plants in the amenitti~ planting zones may need supplemental irrigation for successful establishment (e.g., temporary automatic system, deep pipe delivery with manual watering, or other establishment methods developed in the future). The need for supplemental irrigation would be determined with the test plots. The proposed Reclamation flan Amendment includes separate success criteria for seeded areas and amenity planting zones. Success criteria for seeded areas consist of 25 percent vegetative cover by seeded species b~~ the end of a 120-day plant establishment and warrantti~ period, 40 percent cover by the end of year one, 50 percent by the end of year two, 60 percent by the end of year three, and 70 percent (or more) ultimate cover by seeded species. If these annual cover requirements are not met, re-seeding ma~~ be required as directed by the project biologist. These same criteria apply to seeded species in the amenity zones. In addition, the following success criteria apply to container plants in amenity zones during the five years after planting: 100 percent survival at end of year one, and 80 percent for the remaining four ~~ears. llead container plants shall be tallied annually and replaced as required to meet the success criteria. ~~dditional desired native species established through natural recruitment aho may be counted toward the criteria. Plant vitalitti~ and conformitti~ with established success criteria would be monitored for a total of five ti~ears after the completion of the reclamation activities, or until success criteria have been met, whichever is longer. lluring the first two years monitoring and maintenance would occur on a monthly basis. After the second year, monitoring would occur every other month for three years or until success criteria are achieved, whichever occurs later. In order to meet revegetation standards, vegetation should be self- sustaining for at least the last year of the monitoring period. For areas of revegetation, workers would evaluate the progress of revegetation, reseed any areas where vegetation has failed to establish, and would selectively apply herbicide to any areas with weeds. If plants do poorly because of substandard planting techniques, inferior planting stock, or drought, the same species would be replaced. If a species does poorly in spite of favorable stock, technique, and weather conditions, a qualified botanist or landscape architect would be consulted, and the plant species would be replaced with a more successful species within its plant association. For erosion control areas, workers would aho inspect the slopes and drainages for signs of significant erosion, and would implement erosion control measures, as appropriate. Workers would make any repairs to the irrigation system, if needed; perform erosion control work and fence repair; and remove sediment from ditches and ponds. At the end of the maintenance and monitoring period, if vegetation has properly established and sediment is no longer evident in site drainage, a closure report would be prepared and filed with the City of Chula Vista and the California llepartment of Conservation.

In general, weed suppression is needed for at least two to three years for improved native plant establishment and growth. For this project, a monitoring and maintenance plan would be implemented to promote successful revegetation. The project proposes the use of test plots to confirm the recommended application rates, container densities, and specific mixes. Test plots allow evaluation of the different plant palettes listed in Tables 3-1 through 3-6. Additionally, test plot locations are selected to represent significant microclimates in terms of slope, aspect, and elevation. Test plots would be designed such that no disturbance would occur for a minimum of five years after establishment and would be sufficiently large to quantify success criteria as outlined above. Maintenance would primarily consist of removing weeds to facilitate establishment of desired vegetation. Maintenance personnel should be able to distinguish between desired plants and weeds. Weeding should occur once per month during the first year after planting, and then every three to four months during years two through four. If any revegetated areas would receive supplemental irrigation (as determined by test plots), irrigation-related maintenance may also be required, either to inspect and adjust automatic irrigation systems (if that technology is used), or to deliver water as needed to irrigated plants (if manual/deep pipe irrigation is used). If supplemental irrigation is used, it should extend for at least two years to ensure plant establishment. Monitoring of test plots would be conducted annually by a qualified biologist, after most plant growth has ended (usually late summer). Monitoring consists of measuring percent survival and percent cover of desired species in revegetated areas, and comparing these data with established success criteria (summarized above) for seeded areas and container plants. The monitoring program would last a minimum of five years. 3.5.5 Drainage, Diversion Structures, Waterways, and Erosion Control The proposed Otay Valley Quarry Reclamation Plan Amendment establishes protocol for drainage, diversion structures, waterways, and erosion control at the Project Site, through the use of erosion and sedimentation and groundwater quality, recharge potential, and storage capacity. The specific conclusions and actions to support these goals are crucial in stabilizing the land and preparing for future development, and are as follows: Reclamation operations employ the following erosion and sediment control measures (as necessary): "~'~ Sedimentation basins "~'~ Water truck usage and soil compaction via track walking "'~'~ Diversion of run-on and run-off through the use of temporary chevrons "'~'~ Silt fences, wattles, rock slope protection, or other sediment control devices Preventative maintenance activities are performed as part of the Stormwater Pollution Prevention Plan (SWPPP) program and include the following: "'~'~ Cleaning of accumulated sediment, debris, and potential contaminants from the stormwater structural controls is conducted as needed before the start of the rainy season "'~'~ Clearing of debris from drain inlets and drainage pipes Otay Valley Quarry Reclamation Plan Amendment Page 3-22 Environmental Impact Report (EIR) DRAFT: March 2011; FINAL: June 2011 II ~ uu ~~ ~~~ ~~~~~ 9I ~~~ ~ ~ ~~~ ~~~~ Fuel or other chemicah present on the mine site will be handled and stored using appropriate containment to prevent accidental spillage into open water holies. City-approved spill prevention and emergency response plans outlining guidelines and procedures for handling hazardous materiah will be implemented. 3.G RECLAMATION PHASING AND SCHEDULE 3.6.1 Reclamation Plan Phasing Phasing for implementation of the Reclamation Plan ~~mendment is shown in Figure 3-10, KeclaYnation Phasing. Phasing for the Reclamation Plan ~~rnendment would involve interim-term phases and along-term phase. Installation of revegetation planting and irrigation will commence within sip months of completion of each phase, including the final phase. Intermediate-term phasing occurs in two forms. ~~ portion of intermediate-term phasing could be reclaimed after the construction of Rock iVlountain Road. This portion is depicted in yellow on Figure 3-10. The phase includes the northwest corner of the Project Site, located outside of the iVISCP Preserve boundary. If Rock iVlountain Road is not completed prior to the depletion of mineral resources, this intermediate-term phase will occur with the long-term phase, described below. Intermediate-term phasing aho includes a portion of the Project Site to be reclaimed after reaching the perimeter of the disturbance area. This area, depicted in blue of Figure 3-10, encompasses the bully of the southern portion of the Project Site, the southern houndary, and the northern houndary, all located outside the ~ISCP Preserve houndary. I ong-term phasing (shown in green on Figure 3-10) includes the remainder of the reclamation area, to be reclaimed after mining operations cease. This phase includes the western portion of the Project Site, outside of the iVISCP Preser~re houndary. ~~lso included in this phase is the internal periphery of the reclamation area. 3.6.2 Implementation Schedule The Otav Valley Quarry Reclamation Plan ~~mendment would occur in four scheduled stages. The first stage of reclamation would consist of the removal of all equipment and structures and would take approximately three weeks. The tti~pes of mobile equipment and/or machines to be removed from the site are typical excavation equipment, such as a dozer, front-end wheel loader, portable water pump, motor grader, conveyers, and haul trucks. A water truck is aho on-site for maintenance of surfaces and dust control. This equipment would be removed, along with stationary structures such as the scale and administration building. This phase would require the use of several flatbed trucks, a crane, a 12-person crew, and two excavators.

Grading would ~e accomplished ~y~ utilizing on-site fill materials. This phase would require the use of two bulldozers, one front-end loader, four trucks, one water truck, one excavator, one Made, and a 10-person crew. The third stage would consist of revegetation, which would occur during November through iVlarch for seeding purposes to take advantage of fall/winter rains and would likely last approximately four weeks. Work would ~e performed ~v a licensed landscape contractor specializing in nature revegetation and habitat restoration. This stage would require the use of one bulldozer, several flatbed trucks, a hvdroseed truck, one front-end loader, and hand-held equipment to ~e utilized ~v a 15-person crew. The fourth stage would consist of monitoring and maintenance activities, which would occur over an approximately five-year period, or until plant success criteria has been met, whichever is longer. The proposed project would first ~e required to meet the requirements of the SWPPP/National Pollutant llischarge Elimination System (NPllES) permit which tti~pically~ requires 75 percent vegetative cover for erosion control. SWPPP monitoring would need to ~e performed during construction activities associated with the Reclamation Plan Amendment, as outlined in the SWPPP, and until the Notice of Termination (NOT) is filed and approved. Two years following the execution of the new NPllES permit (2009 0009- llW~, SWPPP monitoring would ~e required to ~e performed ~v a qualified person that has completed State Water Board-sponsored or other State-approved training. Post-NOT monitoring for both erosion and exotics control would ~e performed for approximately three to five years, or until success criteria has been met, whichever is longer. This tti~pe of monitoring is usuallti~ performed quarterly (seasonallti~) ~~~ one or two biologists. iVlaintenance in the way of exotics control would ~e performed monthly for the first sip months and quarterly thereafter ~v a qualified maintenance contractor. iVlaintenance crews would consist of approximately ten people, depending on the amount of exotics control needed. All four stages of reclamation plan implementation would occur during the daytime. No nighttime construction activitti~ would occur. 3.7 DISCRETIONARY ACTIONS A discretionary action is an action taken ~y~ an agency that calls for the exercise of judgment in deciding whether to approve or how to carry out a project. For the proposed Otav Valley Quarr~~ Reclamation Plan Amendment project, approval of the Reclamation Plan Amendment ~v the City of Chula Vista City Council is required. Additionally, review of the Reclamation Plan Amendment by OiVIR is required prior to City approval. Implementation of the proposed Reclamation Plan Amendment would not affect jurisdictional waters or endangered species. Therefore, other State or Federal permits would not ~e required. (See Section 4.6, Biological Kesources, for a discussion of biological resources on and surrounding the Project Site and the project's potential to impact sensitive resources and habitat.)
