Pardee had no information regarding: • Title Records • Environmental site assessment or audit reports • Environmental permits or hazardous waste generator notices/reports • Aboveground and underground storage tanks • Septic systems, oil wells, or water wells • Material Safety Data Sheets; Community Right to Know Plans; or Safety, Preparedness and prevention Plans; Spill Protection Countermeasures and Control Plans • Knowledge of pending, threatened or past proceedings or notices from governmental entities regarding violation, liens, and hazardous substances, or petroleum products. • Specialized Knowledge of Property • Valuation Reduction for Environmental Issues • Owner, Property Manager and Occupant Information • Environmental problems with adjacent or vicinity locations. Pardee Homes provided Converse with topographic maps of the Property. Pardee also provided a letter from the Regional Water Quality Control Board (RWQCB) regarding Cleanup and Abatement Orders (81-13 and 81-27) for the Property. The letter was also included in the file reviewed at the San Diego Regional Water Quality Control Board (RWQCB), and is included as part of the summary in Section 4.4.3. Copies of the RWQCB letter are provided in Appendix D. Converse reviewed Phase I ESAs previously completed by Converse for the eastern adjacent Dennery Ranch property, and the southern adjacent Nakano property. Summaries of the Phase I ESAs are provided below: • Phase I ESA and Limited Phase II ESA Approximate 23 -Acre Nakano Property,Chula Vista California prepared by Converse Consultants dated August 21 2000. The southern adjacent Nakano Property consists of 23 -acres of agricultural land. The site was reported to be sub -divided into three (3) to four (4) individual agricultural plots with a small area used for farm operations, including equipment and a pesticide storage shed. Due to reported agricultural usage at the site, a Limited Phase II ESA was performed. Five (5) soil samples were collected and analyzed for pesticides, herbicides, total recoverable petroleum hydrocarbons (TRPH), and one (1) sample was analyzed for total petroleum hydrocarbons (TPH). Elevated levels of dichlorodiphenyldichloroethane (DDD), dichlorodiphenyldichloroethylene ® Converse Project No. 02-41-346-01 5 (DDE), and dichlorodiphenyltrichloroethane (DDT) were encountered at the pesticide trailer. A second round of sampling consisted of collecting samples in 18 trenches during a geotechnical investigation performed by Pacific Soils. An odor was detected during trenching activities along the northern portion of the Property. Based on Converse's assessment, the following recommendations were made: further subsurface investigation along the northern side of the property to evaluate potential impacts from the historical and present uses of the northern adjacent Davies Property, further subsurface investigation in the area of the pesticide trailer, evaluation of Border Zone issues relative to Burn Ash at Dennery Ranch and the subject property, asbestos and lead -base paint survey prior to building demolition, and abandon septic system in accordance with local regulations. • Phase I Environmental Site Assessment Report, Dennery Ranch Project, Northeast Palm Avenue and Denne Road prepared by Converse Consultants, dated April 14, 1997. Dennery Ranch is 245 acres located east of the Property. Located at the northwest corner of the Dennry Ranch site is an area of dumping. Debris observed included roofing materials, paper, plant material, cans, bottles, and pieces of glass. On April 10, 1997 Converse completed five (5) exploratory trenches to a maximum depth of 15 -feet below ground surface (bgs) in the area of the dumped material on the northwest corner of the property. Burn - ash soil was reported to be present in all trenches. • Addendum No. 1- Burn Ash Fill Area, Dennery Ranch Project San Diego, Califomia, prepared by Converse Consultants dated April 16, 1997. The report indicated that DDD, DDT, and PCB were detected at levels below the Total Threshold Limit Concentration (TTLC). The Department of Toxic Substances Control (DISC) reclassified burn -ash soil as nonhazardous, and on February 14, 1997, DTSC approved the disposal of burn -ash soil at the Otay Annex Landfill with provisions. Converse indicated in the addendum that environmental characteristics of the burn ash are not known, and recommended that the burn -ash should be appropriately removed from the site. Converse also recommended completing test pits and soil sampling to further define the area. • Letter from the Department of Toxic Substances Control DTSC RE: Final Border Zone Property Determination BZP) for the Dennery Ranch Property, dated September 15, 1999. Based on a review of existing information, DTSC indicated the Vincent Davies Property, the South Bay Refuse Disposal Site, and the Omar Rendering Site will not pose a significant threat to future residents of the Dennery Ranch Development. A Voluntary Cleanup Agreement (VCA) was reported to be underway to evaluate the northwest portion of the Dennery Ranch Property which contains burn ash. The DTSC indicated a decision on ® Converse Project No. 02-41-346-01 6 the status of this small portion will be rendered upon completion of the VCA, and that this Border zone property determination was limited only to a review of the potential impacts to Dennery Ranch from the South Bay, Vincent Davies Property, and the Omar Rendering Site. ® Converse Project No. 02-41-346-01 7 4.0 Records Review 4.1 Physical Setting 4. 1.1 Geology The Property is located approximately 80 to 120 -feet above mean sea level (MSL). Surface topography slopes gradually to the northwest towards the Otay River (United States Geological Survey [USGS] Topographic Map, Imperial Beach, 1967 photorevised 1975). The Property is underlain predominantly by alluvium and slope wash deposits (located predominantly in and contiguous with the Otay River), and stream -terrace deposits (located along the banks of the Otay River). The deposits are composed primarily of unconsolidated sand and gravel derived locally from the sedimentary, igneous, and metamorphic rocks in the area (California Division of Mines and Geology, Otay Mesa Quadrangle, California, 1977). 4.1.2 Groundwater The Property is not covered by current published groundwater contour maps. Regional groundwater flow is inferred to follow regional surface topography towards the west-southwest. According to a May 30, 1996 San Diego Department of Environmental Health Closure Letter for Voluntary Assistance Program, Case #H28262-001, regarding the northern adjacent property, located at 4501 Otay Valley Road, Chula Vista, California, depth to groundwater is approximately 30 to 35 -feet below ground surface. 4.1.3 Fault Zones Located approximately 1/2 -mile south of the Property is the La Nacion Fault Zone and Sweetwater Fault. The La Nacion Fault is an early Quaternary fault that has experienced displacement within the past 200-700,000 years (California Division of Mines and Geology [DMG], Preliminary Fault Activity Map of California, 1992). The DMG classified the La Nacion Fault as a "potentially active" fault, indicating surface displacement in Quaternary time. The Property is not located within an Alquist-Priolo earthquake fault zone (California Department of Conservation, DMG, Official Map of Alquist-Priolo Earthquake Fault Zones, 2000). ® Converse Project No. 02-41-346-01 8 4.1.4 Potable Water Supplier Potable water is supplied by the Otay Water District. 4.1.5 Flood Zone According to the Federal Emergency Management Agency (FEMA), Flood Insurance Rate Map #06073C2158 F, Panel 2158, dated June 1997, the Property is located in areas designated as Flood Zone AE and X. Flood Zone AE is defined as where the base flood elevation is determined to be between 88 and 89 -feet. Flood Zone X is defined as an area determined to be outside a 500 -year floodplain. 4.1.6 Radon The Property is located in San Diego County, which is classified as Zone 3 by the United States, Environmental Protection Agency (EPA). Zone 3 is defined as having a predicted average screening level of less than 2 pCilL (EPA Map of Radon Zones, 1993). 4.2 Historical Review 4.2.1.

A chronological summary of the permits is provided below. In March 1987, Aubert Davies was issued an electrical permit to install a service pole. In July 1992, Tom Davies was issued an electrical permit to install a temporary power pole, and in October 1992, an electrical permit was issued to add a meter to the existing pole. In March 1994, Vince Davies was issued an electrical permit to install a temporary power pole. 4.3 Regulatory Database Search A regulatory database search was completed on the Property by EDR. The complete EDR report is provided in Appendix C, EDR-Radius Map Report. The Property was identified in the EDR Report under current and historical addresses in the following databases: • Vincent Davies Property, EDR Map ID # 1, located at 4501 Otay Valley Road. The current address for the Property was reported in the Cal -Sites database, which contains potential or confirmed hazardous substance release properties. • Apache Services, EDR Map ID #2, located at 4551 Otay Valley Road. The historical address for the Property was reported to be part of the California Bond Expenditure Plan developed by the Department of Health Services, which is a site -expenditure plan developed as the basis for an appropriation of Hazardous Substance Cleanup Bond Act funds. It was reported that Department of Toxic Substances Control (DTSC) action was not required, and that the Property was referred to RWQCB lead. Off-site locations of environmental concern identified in the EDR report include: • Fuller Ford Honda, EDR Map ID # 139, located at 560 Auto Park Drive (approximately 1/4 to'/Z-mile northeast of the Property), was reported to be a Resource Conservation and Recovery Information System Small Quantity Generator (RCRIS-SQG) of hazardous waste. The site was listed on the Facility Index System (FINDS) which contains both facility information and ® Converse Project No. 02-41-346-01 12 pointers to other sources that contain more detail, the Hazardous Waste Information System (HAZNET) which extracts data from copies of hazardous waste manifests received each year by the DTSC, and the San Diego Hazardous Materials Management Division Database (HMMD). The site was reported to generate paint sludge, unspecified aqueous solution, and unspecified sludge waste. The disposal method was reported to be a recycler. The HMMD disclosure inventory includes: antifreeze, acrylic lacquer and enamel paints, helium, soap -detail chemicals/castrol, lacquer thinner -acetone, petroleum naptha, Stoddard solvent, acetylene compressed gas, argon/carbon dioxide compressed gas, dimethyl benzyl ammonium chloride, base lubricating oil, and oxygen compressed gas. The violations reported include: lack of hazardous waste manifests on-site, improper labeling of hazardous waste, hazardous waste containers not properly closed, and disposal of hazardous waste to an unauthorized point (ground, storm drain, sewer system, trash, or air). • Peoples Chevrolet, EDR Map ID #1310, located at 580 Auto Park Drive (approximately 1/4 to '/Z -mile northeast of the Property), was reported to be a RCRIS-SQG, and was listed as a FINDS, HAZNET, and San Diego HMMD site. The site was reported to generate unspecified organic liquid mixture, unspecified solvent mixture waste, unspecified oil -containing waste, and aqueous solution with less than 10% total organic residues. The HMMD disclosure inventory includes motor oil and grease, dichlorodifluoromethane (R-12 Freon), and antifreeze. The violations reported included used oil filters not being properly drained, stored, or labeled prior to transport, personnel training records deemed inadequate, inadequate labeling of hazardous materials, hazardous waste containers were reported to be open while in storage, business plan was not amended within 30 days for a 100% quantity increase, hazardous waste storage container was reported to be leaking or in poor condition, disposal of hazardous waste was reported to be an unauthorized point. • Crown Chemical Corporation, EDR Map ID #28, located at 1888 Nirvana Avenue (1 -mile east of the Property), was reported to be a RCRIS-SQG, and was listed as a FINDS site. The property was also reported to be a Cortese hazardous waste and substances site list, and a leaking underground storage tank (LUST) site. One RCRIS violation was reported: generator -all requirements (oversight), which was complied with in July 1985. The LUST was reported as a gasoline leak. The case type was reported to be other groundwater affected, and the status was reported to be preliminary site assessment workplan submitted. Other off-site locations of environmental concern included in the EDR Orphan Summary include: ® Converse Project No. 02-41-346-01 13 • Shinohara II Burnsite, located south of 4705 Otay Valley Road. The property was reported to be a solid waste facility or landfill (SWF/LF). • Shinohara 11, located on Otay Valley Road. The property was reported to be a SWF/LF. See Section 4.4.5, County of San Diego DEH HMMD, for more information regarding the Shinohara Property. Other off-site locations of environmental concern identified by EDR included permitted hazardous waste sites, hazardous waste generators, landfills, and leaking underground storage tank sites. The potential for environmental impact to the Property from the other off-site locations appears to be low due to one or more of the following: distance from the subject Property; location with respect to the direction of regional groundwater flow; status of the case; type of resource affected, remedial efforts being directed by a regulatory agency; and/or potential responsible parties have been identified. 4.4 Additional Regulatory Agency Record Sources 4.4.1 Division of Oil and Gas (DOG) California Department of Conservation, DOG, Wildcat Map W1-7, San Diego and Riverside Counties, August 18, 2001. No oil or gas wells are located on the Property. 4.4.2 California State Fire Marshall (CSFM), Pipeline Safety Division According to the CSFM, there are no pipelines in CSFM's jurisdiction in the vicinity of the Property. 4.4.3 San Diego Regional Water Quality Control Board (RWQCB) File #06-0036.02, "Vincent Davies Apache Services Dumpsite, 09/81 — 03185", was reviewed. A summary of the documents reviewed is provided below, and in Appendix D, User and Agency Documents. • The RWQCB first became involved with the Property in February 1981. Cleanup and Abatement (C&A) order 81-13, "Apache Service Site," located at 4551 Otay Valley Road, was issued for a salvage operation conducted on the central and eastern portions of the Property. All containers of toxic and hazardous materials were inventoried and disposed of in late 1981. Soil samples collected by the Department of Health Services (DHS) in May 1984 indicated that the soil on the Property ® Converse Project No. 02-41-346-01 14 was not contaminated by hazardous material. The RWQCB concurred, and considered C&A Order 81-13 to be satisfied in 1984. • C&A Order No. 81-27 " Vincent Davies Property — Otay River Valley (4501 Otay Valley Road)," was issued due to use of waste sandblasting grit as fill material on the central and eastern portions of the Property. C&A Order No. 81-27 required that the fill area surrounding the salvage yard be adequately characterized with respect to potential impacts to water resources in the area. Total concentrations of several heavy metals were found to be elevated above background levels. Three (3) monitoring wells were installed to monitor the leaching potential of the sandblast grit fill (information regarding the wells is included Section 4.4.5, County of San Diego DEH HMMD). Water samples collected from the wells in 1988 and 1989 revealed low quantities of metals. The RWQCB concluded that it was unlikely that the Otay River was being adversely affected by leachate generated from the Property. In June 1989, fish were collected from a river pond adjacent to Property. Fish tissue samples were analyzed for the presence of toxic constituents as part of the State's Toxic Substances Monitoring Program. Laboratory results received by the RWQCB indicated only very low levels of heavy metals were present within the fish. in addition, Mr. Vincent Davies placed a cap (type and depth of cap was not reported) on the fill and constructed a perimeter ditch around it to prevent the intrusion of all off-site storm water runoff. The RWQCB considered C&A Order 81-27 to be satisfied in July 1990. A 'Report of Investigation for Otay ValleV Disposal SitePerformed bv C.H. Wood and Associates, dated August 13, 1986 (provided in San Diego Department of Environmental Health file # H28262-001, Davies Voluntary Assistance Program Case (below), and in Appendix E) was performed to determine the extent of contaminated soil, investigate the probability of contaminants leaching into the subsoils, and to recommend remedial measures in regard to disposal or treatment of "contaminating elements." A summary of the investigation is provided below. • Three (3) long pits (Pits #101, 102, 103) were dug on the Property in August 1985 (locations of pits included in Appendix D) to determine location of sandblast grit fill on the Property. The soils encountered at the site were reported to consist of assorted debris characteristic of a refuse disposal site for construction debris and sandblast grit fill. C.H. Wood and Associates (CHWA) indicated that native soils underlying the fill were comprised of sandy clays and clayey sands. The placing of the sandblast grit fill was reported to be random. Pit #102 was reported to contain "gray -black ash that is the result of burned debris mixed with soil." Standard tests prescribed by the Regional Board (Total Threshold Limit Concentration (TTLC) and Standard Threshold Limit Concentration ® Converse Project No. 02-41-346-01 15 (STLC)) were performed on the sand and adjacent soils. Analytical test results are provided in Appendix D. CHWA indicated that little or no leaching had occurred because soil samples taken adjacent to obvious pockets of sandblast grit "compared well with areas where we are relatively certain that no toxic concentrations are located." CHWA indicated that additional tests of sandblast grit concentrated areas as well as adjacent areas showed that leaching potential was very low, and that existing fill soil contained large amounts of clay (low permeability). CHWA indicated leaching could be monitored by groundwater observation wells, with the alternative of removal and exportation of the contaminated fill if future leaching was detected, or as future land use and value dictated. CHWA also recommended that the sandblast grit fill be capped with 6 - inches of impermeable clay, and a 6 -inch protective blanket. 4.4.4 San Diego Air Pollution Control District (APCD) The San Diego APCD records search revealed no files regarding the Property. 4.4.5 County of San Diego, Department of Health (DEH), Hazardous Materials Management Division (HMMD) The following file regarding Paco's Truck Repair, a commercial auto repair business historically located on the Property, was reviewed. A summary of the documents reviewed is provided below. • File # H28262, Paco's Truck Repair On March 15, 1992, a release of several hundred gallons of road topping oil/asphalt occurred near the south bank of the Otay River. A vacuum truck was able to recover 200 -gallons of the spilled asphalt. The HMMD confirmed all contaminated soils had been disposed of before excavated areas were closed. In February 1998, an HMMD inspection was conducted on the Property. Notices of Violation were issued for the following observed conditions: antifreeze on floor surface, improper labeling of hazardous waste containers, waste containers not kept closed, training records unavailable, training program inadequate, and lack of implementation of business plan. In July 1999, an HMMD inspection was conducted on the Property. Notices of Violation were issued for the following observed conditions: improper labeling of waste materials, inadequate training records, and lack of implementation of business plan. ® Converse Project No. 02-41-346-01 16 In October 2001, an HMMD inspection was conducted on the Property. The following notices of violation were issued: waste containers missing proper labels, lack of employee training documentation. It should be noted that Paco's Truck Repair was not observed during Converse's Property reconnaissance. The following files regarding adjacent properties and off-site locations of potential concern were reviewed. The following is a summary of files reviewed in addition to the files reviewed in Section 4.4.3. • File # H28262-001, Davies Voluntary Assistance Program am Case The HMMD file contained information regarding the northern adjacent property (also has address of 4501 Otay Valley Road), located north of the Otay River. According to the HMMD Closure Summary, dated May 21, 1996, the site was impacted by elevated petroleum hydrocarbons concentrations due to: former releases of used motor fuel, on-site operations, and diesel fuel from aboveground storage tanks (ASTs). The petroleum -impacted soil was excavated to a depth of 28 -feet below ground surface. Groundwater was reported to be 30 to 35 -feet below ground surface. Laboratory analysis of groundwater samples collected from two (2) monitoring wells (exact location not reported) indicated that toluene was present in the groundwater at a concentration of 2.5 micrograms per liter (Ng/L). Aboveground passive bio -remediation treatment of the impacted soil was performed, and the treated soil was left on-site. The HMMD indicated that there was no apparent threat to public and/or environmental health, and issued a No Further Action letter on May 21, 1996. • File #91911, Shinohara Farms, Parcel 8 This site was reported to be located between Otay Valley Road and the Otay River, approximately 3/ -mile northeast of the Property. According to the HMMD file, this site consisted of approximately 18 acres. From the 1940s to the 1990s the land was used as agricultural property. Fill material was accepted by the property owner to expand the agricultural acreage along the Otay River. The fill material has been identified as bum -ash soil. In October 1992, a limited subsurface investigation was completed at the site. Test pits revealed glass shards and fused glass in the subsurface, suggesting that fill materials were composed of bum -ash containing soils. A soil sample, collected at 16 feet, contained a concentration of lead greater than the Total Threshold Limit Concentration (TTLC) of 1,000 milligrams per kilogram (mg/kg). Subsequently, seven (7) additional borings/samples were collected and ® Converse Project No. 02-41-346-01 17 analyzed for lead. All seven of the samples exceeded the TTLC for lead. In October 1993, three (3) groundwater wells were installed to evaluate if groundwater in the immediate vicinity of the site had been impacted by the burn -ash. The groundwater samples collected were not reported to be impacted by the burn -ash soil at the site. Also in October 1993, burn -ash soil at the site was reported to be excavated and stockpiled. Samples collected from stockpiled soils were not reported to exceed regulatory action levels. In May 1994, the site was reported to be under redevelopment as an auto park. • File # H2O13897011467, Shinohara Farms The file indicated the Shinohara site was located 118 -mile south of Otay Valley Road, and north of the Otay River. The site was issued a No Further Action letter in 1991 for the removal of a 550 -gallon diesel underground storage tank (UST), and a 550 -gallon gas UST. • He # H34845, Fuller Ford In May 1995, a HMMD inspection indicated that hazardous waste was being discharged into a storm drain, which emptied into the Otay River. In June 1998, a routine inspection was conducted on the property. Notices of Violation were issued for improper labeling of waste, and inadequate employee training. In September 1998, a HMMD inspection was conducted. Corrective action was suggested to label waste containers, close containers, and transfer waste from damaged containers to new ones. Otherwise Fuller Ford was noted as a clean facility. In June 1999, a HMMD inspection was conducted. Notices of Violation were issued for missing hazardous waste labels, lack of hazardous waste manifests, open waste containers, and disposal to an unauthorized point. In October 2002, a HMMD inspection was conducted. No violations were reported. • File # H02203. Crown Chemical Corn. ® Converse Project No. 02-41-346-01 18 Crown Chemical Corp is located approximately 1 -mile northeast of the Property. In June 1997, removal of several chlorinated solvent and gasoline USTs revealed that petroleum hydrocarbons and chlorinated solvents had impacted the soil in the tank excavation area. Further investigation revealed that the chlorinated solvents and petroleum hydrocarbons leaked from the USTs, and reached the groundwater beneath the property. Beginning in November 2000, quarterly groundwater monitoring well samples were collected from five (5) wells located on or near the site. Analytical results from November 2000 to October 2002 revealed the following concentrations of chemicals of potential concern: tetrachloroethene concentrations from non -detect (ND) to 1,700 parts per billion (ppb), trichloroethene concentrations from ND to 79 ppb, and 1,1-dichloroethene concentrations from ND to 230 ppb. 4.4.6 County of San Diego, Department of Agriculture, Weights, and Measures The Department of Agriculture, Weights, and Measures record search revealed no files regarding the Property. ® Converse Project No. 02-41-346-01 19 5.0 Site Reconnaissance 5.1 Methodology On Wednesday, January 15, 2003, Converse visited the Property to evaluate present use and environmental conditions at the Property.

Mr. Davies had no information regarding: • Title Records • Environmental site assessment or audit reports • Environmental permits or hazardous waste generator notices/reports • Aboveground and underground storage tanks • Septic systems, oil wells, or water wells • Material Safety Data Sheets; Community Right to Know Plans; or Safety, Preparedness and prevention Plans; Spill Protection Countermeasures and Control Plans • Knowledge of pending, threatened or past proceedings or notices from govemmental entities regarding violation, liens, and hazardous substances, or petroleum products. • Valuation Reduction for Environmental Issues • Owner, Property Manager and Occupant Information • Environmental problems with adjacent or vicinity locations. In the owner interview, Mr. Davies indicated that the Property is currently used for storage, auto towing, and trucking. Mr. Davies indicated that there are no sewage disposal/septic systems on the Property. During the Property reconnaissance, Mr. Davies indicated the Property was eight (8) acres total, three (3) of them being in the Otay River. He indicated the northern Property line was located from the large billboard (northwestern comer) to the fence posts (northeastern corner). Mr. Davies indicated that he has an agricultural grading permit for the fill located on the Property, and that the three (3) monitoring wells installed to monitor the sandblast - grit fill had not been removed. Mr. Davies' son, Tom Davies, indicated there were no hazardous waste, underground storage tanks (USTs), or aboveground storage tanks (ASTs) located on the Property. Mr. Tom Davies indicated that the northeastern adjacent property was owned by Mr. Shinohara (see Figure I in Appendix A — Property Plan). Mr. Tom Davies also indicated that no burn -ash soil had been brought onto the Property. Mr. Tom Davies also identified the approximate location of the sandblast -grit fill on the Property to be the central and eastern portions of the Property, but was unable to provide the exact location. Mr. Tom Davies also indicated the location of one (1) of the monitoring wells to be located along the southern bank of the Otay River on the north -central portion of the Property. ® Converse Project No. 02-41-346-01 27 6.2 Regulatory Agency Converse contacted the San Diego RWQCB regarding a possible re -review of the closure for Cleanup and Abatement Order 81-27 for the Apache Services Dumpsite. A re -review of the file was requested due to concerns regarding existing on-site sandblast grit fill related to the Property's proposed redevelopment as either open space or park land. Mr. John Odermatt of the San Diego RWQCB indicated that Cleanup and Abatement Order 81-27 was satisfied as far as the RWQCB was concerned, but suggested that Converse contact the County of San Diego, Department of Environmental Health (DEH), Solid Waste Local Enforcement Agency (LEA). Converse contacted Melissa Porter of the LEA, and she requested additional information regarding the size and quantity of the cap which was placed over the fill and how the Property would be maintained once it was redeveloped. ® Converse Project No. 02-41-346-01 28 7.0 Findings, Opinions and Conclusions Converse has performed a Phase I Environmental Site Assessment in general conformance with the scope and limitations of ASTM Practice E 1527-00 for 4501 Otay Valley Road, in the City of Chula Vista, San Diego County, California. Any exceptions to or deletions from this practice are described in the Limitations and Exceptions of Assessment section of this report. This assessment has revealed no evidence of recognized environmental conditions in connection with the Property except for the following: • The following two C&A orders were issued by the RWQCB to the Property owner, Vincent Davies: • C&A order 81-13, "Apache Service Site" was issued for a salvage operation conducted on the central and eastern portions of the Property. All containers of toxic and hazardous materials were inventoried and disposed of in late 1981. Soil samples collected by the Department of Health Services (DHS) in May 1984 indicated that the soil on the Property was not contaminated by hazardous materials. The RWQCB issued a letter in 1984 indicating that no further assessment appeared warranted. • C&A Order No. 81-27 " Vincent Davies Property — Otay River Valley," was issued due to use of waste sandblasting grit as fill material on the central and eastern portion of the Property. C&A Order No. 81-27 required that the fill area surrounding the salvage yard be adequately characterized with respect to potential impacts to water resources in the area. Total concentrations of several heavy metals were found to be elevated above background levels. Three monitoring wells were installed to monitor the leaching potential of the sandblast grit fill. Water samples collected from the wells in 1988 and 1989 revealed low quantities of metals. The RWQCB concluded that it is unlikely that the Otay River was being adversely impacted by leachate generated from the site. In June 1989, fish were collected from a river pond adjacent to Property. Tissue samples were analyzed for the presence of toxic constituents as part of the State's Toxic Substances Monitoring Program. Laboratory results received by the RWQCB indicated only very low levels of heavy metals were present within the fish. In addition, Mr. Vincent Davies placed a cap on the fill (type of cap was not reported) and constructed a perimeter ditch around it to prevent the intrusion of all off-site storm water runoff. The RWQCB considered C&A Order 81-27 to be satisfied in July 1990. The RWQCB indicated that further assessment does not appear to be warranted. ® Converse Project No. 02-41-346-01 29 • A C.H. Wood and Associates investigation on the Property, performed in August 1986, reported the presence of burn -ash in a pit dug on the central portion of the Property. • The Property is currently occupied by Monroy Towing Company, an unimproved road, Lora's Towing Company, Lamar Portable Toilets and Classrooms, and a storage bin lot. The following environmental concerns are associated with current uses of the Property: • A 55 -gallon drum and several smaller drums (20 to 40 -gallons each) of waste oil were observed at Lora's Towing on the southeast -central portion of the Property. Leaking and significant staining were observed. • A paint spray area was observed on the northern portion of Monroy's Towing. Two (2) 5-galion containers of paint thinner and 14 1 -gallon containers of paint were also observed. Minor staining was observed in the immediate vicinity. • Fourteen (14) car batteries were observed to be cleaned out on the soil on the southwestern portion of Monroy's Towing. Staining was observed on the dirt beneath the batteries. • Approximately 50 portable storage bins were observed on the eastern portion of the Property. The interiors of ten (10) of the bins were accessed, and observed to be empty. Staining was observed on the dirt around the trailers. • Four (4) unlabeled 15 55 -gallon drums were observed on the western portion of Monroy's Towing. Minor staining was observed. • Two (2) 55 -gallon drums were observed on the southeastern portion of Monroy's Towing. The labels were weathered and undistinguishable. Minor staining was observed. Approximately 5 -gallon plastic containers of waste oil were also observed on the southeastern portion of Monroy's Towing. Significant leaking and staining were observed. • Staining was observed beneath the portable classrooms on the eastern - central portion of the Property, on the soil beneath the auto vehicles stored at Monroy's Towing (southwestern portion of the Property), and at Lora's Towing. A cement pad located in the carport of Lora's Towing was observed to be stained. Stained soil was also observed on the northwestern portion of Monroy's Towing (southwestern portion of the Property). • Automobile tires were observed scattered throughout the Property. ® Converse Project No. 02-41-346-01 30 • A large pile of railroad ties was observed at the southeastern corner of the Property. • Several residential structures were observed on the Property. No septic tank, sewer system, or clarifier was observed. • Historical information has indicated that portions of the Property were agricultural as early as 1928 to at least 1983. There appears to be a potential for residual pesticides/herbicides impact to the Property from historical agricultural usage. • Soil containing burn ash was observed on the northeastern adjacent property approximately 25 -feet east of the eastern Property boundary line. Mr. Tom Davies indicated the site was owned by Mr. Shinohara. Additional burn ash may exist in that area. • Shinohara Parcel eight (8), consisting of 18 acres of land, located approximately 3/ -mile northeast of the Property, was reported to contain fill consisting of burn - ash soil. Groundwater samples collected did not indicate an impact to the groundwater due to burn -ash soil on site. Soil samples collected from stockpiled soil on-site were reported to contain concentrations below regulatory action levels. In 1994 the site was reported to be under development as an auto park. • Shinohara farms was reported to be located 1/8 -mile south of Otay Valley Road, and north of the Otay River, approximately 3/ -mile northeast of the Property. The site was issued a No Further Action letter in 1991 for the removal of a 550 - gallon diesel underground storage tank (UST), and 550 -gallon gas UST. • A San Diego DEH Case Closure Summary, dated May 21, 1996, reported the northern adjacent property was impacted by elevated petroleum hydrocarbons concentrations due to the following: former releases of used motor fuel, on-site operations, and diesel fuel from ASTs. The petroleum -impacted soil was excavated to a depth of 28 -feet below ground surface. Laboratory analysis of groundwater samples collected from two (2) monitoring wells indicated that toluene was present in the groundwater at a concentration of 2.5 ug/L. Aboveground passive bio -remediation treatment of the impacted soil was performed, and the treated soil was left on-site. The HMMD indicated that there was no apparent threat to public and/or environmental health, and issued a No Further Action letter on May 21, 1996. • A San Diego HMMD inspection of Fuller Ford Honda (560 Auto Park Drive) in May 1995, indicated that hazardous waste was being discharged into a storm drain which emptied into the Otay River. The Otay River makes up the northern and northwestern portions of the Property. There appears to be a potential for impact to the Property from historical dumping of hazardous materials and/or waste into the Otay River. ® Converse Project No. 02-41-346-01 31 Based on the above information, there appears to be a potential for environmental impact to the Property from current and historical usage of the Property and adjacent properties. Further assessment appears warranted at this time. Converse recommends the following: • Inform the San Diego County LEA as to the amount of cap and/or protective blanket placed over the sandblast grit fill located on the Property prior to re- development, and obtain closure for redevelopment prior to acquisition. • Prior to acquisition of the Property, samples should be collected along the eastern boundary of the Property, and on the central portion of the Property to assess any impact to the Property from burn -ash. • Evaluation of Border Zone issues relative to burn -ash at Dennery Ranch and the Property. • Soil sampling in the following areas of staining: in the vicinity of the storage bins and railroad ties on the eastern portion of the Property, stored automobiles on the central and southwestern portions of the Property, waste oil drums and stained cement pad on the northern central portion of the Property, waste oil drums and unlabeled drums on the southwestern portion of the Property, a paint spray booth on the southwestern portion of the Property, and used car batteries on the southwestern portion of the Property. • Soil sampling on the central portion of the Property beneath the porta potties due to pooling of water and cleaning agents in the immediate vicinity. • Soil sampling on the central portion of the Property on account of Notices of Violation (related to hazardous waste) issued by San Diego Department of Environmental Health, Hazardous Materials Division, to Paco's Truck Repair (historically located on the Property). • Sediment and water sampling in the Otay River on the northern portion of the Property due to sandblast fill located on the Property, and release of hazardous waste into the river from an upgradient off-site location. • Sampling and abandonment of groundwater wells located on the northern portion of the Property. • An asbestos and lead -base paint survey on roofing material debris pile and existing structures on the Property prior to demolition. Removal of tires, batteries, and drums prior to acquisition of the Property. ® Converse Project No. 02-41-346-01 32 Interview occupants of residential structures on the Property to evaluate possible presence of clarifier, sewer system, or septic tank. ® Converse Project No. 02-41-348-01 33 8.0 References California Department of Conservation, Division of Oil and Gas, Regional Wildcat Ma W1-7, San Diego and Riverside Counties, August 18, 2001.

Elevations have been determined from the USGS 1 degree Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. EDR's definition of a site with an elevation equal to the target property includes a tolerance of +1- 10 feet. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property (by more than 10 feet). Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed. Sites listed In bold italics are in multiple databases. Unmappable (orphan) sites are not considered in the foregoing analysis.

NFRAP sites may be sites where, following an initial investigation, no contamination was found, contamination was removed quickly without the need for the site to be placed on the NPL, or the contamination was not serious enough to require Federal Superfund action or NPL consideration. EPA has removed approximately 25,000 NFRAP sites to lift the unintended barriers to the redevelopment of these properties and has archived them as historical records so EPA does not needlessly repeat the investigations in the future. This policy change is part of the EPA's Brownfields Redevelopment Program to help cities, states, private investors and affected citizens to promote economic redevelopment of unproductive urban sites.

For example, the existence of wetlands information data in a specific report does not mean that all wetlands in the area covered by the report are included. Moreover, the absence of any reported wetlands information does not necessarily mean that wetlands do not exist in the area covered by the report. Oil/Gas Pipelines/Electrical Transmission Lines: This data was obtained by EDR from the USGS in 1994. It is referred to by USGS as GeoData Digital Line Graphs from 1:100,000 -Scale Maps. Itwas extracted from the transportation category including some oil, but primarily gas pipelines and electrical transmission lines. Sensitive Receptors: There are individuals deemed sensitive receptors due to their fragile immune systems and special sensitivity to environmental discharges. These sensitive receptors typically include the elderly, the sick, and children. While the location of all sensitive receptors cannot be determined, EDR indicates those buildings and facilities - schools, daycares, hospitals, medical centers, and nursing homes - where individuals who are sensitive receptors are likely to be located. Flood Zone Data: This data, available in select counties across the country, was obtained by EDR in 1999 from the Federal Emergency Management Agency (FEMA).

Section 7.2.3 requires that a current USGS 7.5 Minute Topographic Map (or equivalent, such as the USGS Digital Elevation Model) be reviewed. It also requires that one or more additional physical setting sources be sought when (1) conditions have been identified in which hazardous substances or petroleum products are likely to migrate to or from the property, and (2) more information than is provided in the current USGS 7.5 Minute Topographic Map (or equivalent) is generally obtained, pursuant to local good commercial or customary practice, to assess the impact of migration of recognized environmental conditions in connection with the property. Such additional physical setting sources generally include information about the topographic, hydrologic, hydrogeologic, and geologic characteristics of a site, and wells in the area. Assessment of the impact of contaminant migration generally has two principle investigative components: 1. Groundwater flow direction, and 2. Groundwater flow velocity. Groundwater flow direction may be impacted by surface topography, hydrology, hydrogeology, characteristics of the soil, and nearby wells. Groundwater flow velocity is generally impacted by the nature of the geologic strata. EDR's GeoCheck Physical Setting Source Addendum is provided to assist the environmental professional in forming an opinion about the impact of potential contaminant migration.

If such data is not reasonably ascertainable, it may be necessary to rely on other sources of information, such as surface topographic information, hydrologic information, hydrogeologic data collected on nearby properties, and regional groundwater flow information (from deep aquifers). TOPOGRAPHIC INFORMATION Surface topography may be indicative of the direction of surficial groundwater flow.

BOX 85261 SAN DIEGO, CA 92186-5261 (619) 338-2222 February 21, 1992 VINCENT DAVIES PROPERTY SUMMARY Between 1978 and 1981, approximately 2,000 truckloads of sandblasting grit from ship yards and boat yards in .the Sar. Diego area were used as fill material on the Davies Property. This fill was deposited both north & south of the Otay Valley River which flows through the Davies Property. The exact source(s) of 'this disposal is not know at this time. However, information provided to HNLMD by responsible Party (RP) Is attorney (telephone conversation) has revealed that apparently a sandblasting grit waste generator and waste transporter by the name Of Southwest Marine and a local waste transporter by the name of Sanitainer, Inc. (Now under the management of Laid Law Environmental Company) were among the waste disposal contributor to this sit. The RP's attorney has also indicated that'his client, Mr. Vincent Davies, was not told by any of the above referenced companies about the nature of this waste and nor his client received any laboratory test results in connection with the disposed material.. In 1981, the Regional Water Quality Control Board (RWQCB). issued two cleanup and abatement (C&A) order. The first C&A order "Apache Service Site" was in connection with salvage operation located on the south side of Otay River and the second C&A order Was issued for the use of waste sandblasting grit which surrounds the salvage yard. The RWQCB considered both C&A orders to be satisfied in May 1984 and July 1990 respectively. In 1991, RP.prepared a Waste Discharge Report for sandblasting grit deposited on the northern portion of his ;property to RWQCB and EPA conducted a Preliminary. Assessment (PA) on this property. Because of RWQCB staff limitations, the RP has requested oversight assistance from HMMD the results of EPA investigation has not been released to this date. Laboratory results from soil samples collected from sandblast grit- located ritlocated in the south portion of Davies property have shown a high concentration of heavy metals above allowable levels. Having the same type of waste contamination, it is'highly likely that the -2 - Mr. Vincent Davies February 21, 1992 sandblast grit deposited in Davies Property located in the north side of Otay Valley River is a hazard to public health and it is a potential source of hazardous waste discharge to the environment particularly Otay Valley River. Responsible Party: Vincent Davies 4501 Otay Valley Road Chula Vista, CA 92011 WP; DAVIES. LAN Chronological Events of Davies Property 4501 Otay Valley Road Chula Vista, CA 1978-1981 Approximately 2,000 truckloads of sandblasting grit from shipyards and boatyards in the San Diego area were used as fill on the Davies property. This fill was deposited both north and south of. the Otay River which flows through the Davies property. February 1961 First involvement of California Regional Water Quality Control Board (RWQCB) - San.Diegc Region at this site. Two cleanup and abatement order No. 81- 13 and No.'81.-27 were issued. C & A Order No. 81-13 "Apache "Service Site" was issued for a salvage operation being conducted on property. Within the salvage yard were containers of toxic and hazardous waste. C & A Order • No. '81-27 "Vincent Davies Property - Otay River Valley's was issued for the use of waste sand blasting grit as fill material on the property which surrounds the salvage yard. The subject property attained its position on the State Superfund listing because of the hazardous wastes which were identified at the salvage yard. The above C & A orders were issued to the portion of Davies property located south of Otay Valley River. Late 1981 All containers of toxic and hazardous materials were inventoried and removed from the salvage yard in late 1981. May 1984 Soil samples were collected by the- Department of Health Services (DOHS). Analyses indicate that the soil at the site is not contaminated by Hazardous material.- Concurring with the DOHS, the RWQCB considered C & A Order No.. 81-13 to be satisfied in 1984. 1985 A Report of Waste Discharge in connection with the sandblasting grit on south of the Otay River was filed. Compliance with C & A Order 81-27 was required that the fill material surrounding the salvage yard be adequately characterized and the potential threat to the water resources in the area be evaluated. 7-18-86 C.H.

The )rised of waste sand from MS. The waste sand includes ily of heavy metals such as which are contained in dry paint that was removed from the boat bottoms. Their recommendations were: 1) construct an interceptor ditch upslope along the property line, 2) slope to drain, 3) cap the surface with 6" of relatively impervious soil, 4) place 3 observation wells along the edge of the filled pad to allow sampling and testing of the ground water. Sample and test on a six month schedule. 1988-89 Water samples from 3 observation wells revealed only low levels of heavy`metals many being at or below the limit. of detection. Fish were collected from a river pond adjacent to the fill site in June 1989 and tissues were analyzed as part of the State Toxic Substances Monitoring Program (TEMP). The results indicated very low levels of heavy metals were present within these fish. Owner placed -a cap on the. fill - and constructed a perimeter ditch around it. Copies. of the final monitoring report, all progress reports., the 1989 TSMP, and all RWQCB data and files are available in the RWQCB office. 7-13-1990 The RWQCB San Diego Region determined that the fill material at this site was unlikely to adversely impact the water resources and associated beneficial uses of the Otay River, and determined that Order No. 81-27 had been satisfied. (signed by .Mr. Art Coe). The RWQCB also expressed their recommendation for the removal of this site from the State Superf and listing. 10-12-90 At the request of the City of Chula Vista Redevelopment Department, Dames and Moore Environmental Consultant conducted an Environmental Site Assessment on Vincent Property located on North of Otay Valley River. This investigation addressed issues relating to soil contamination associated' with waste oil and diesel contamination and did not address issues relating to soil contamination associated with fill material containing sandblasting waste. Their findings are as follows: The highest waste oil contamination detected contained 75,600 PPM waste oil contamination appears to extend to depths of 3 to 5 feet below ground surface (bgs) . The highest concentration of diesel in the soil detected contained 12,000 PPM and it appears the diesel contamination extends to depth of approximately 20' bgs. The estimated volume of contaminated soil is approximately 8,500 cubic yards (1,800 Diesel & 6700 cubic yards of waste oil). An unknown fraction of .waste oil: soils may contain heavy metals at concentration which would classify the soils as hazardous waste. In 1989-90 Dames & Moore conducted Preliminary field investigation in seven areas (identified as A through G.) north of Otay Valley River by drilling 18 shallow hand -anger borings. Drilling refusal occurred in several of the borings due to the cobbly nature of geologic formation. North of the site geology consists of sandstone member of the San Diego Formation. Ground water is generally encountered in alluvial deposits and the San Diego Formation at depths ranging from less than 25 feet to greater than 100 feet. A 300 gallon regular gasoline under -ground storage tank (UST) is located at this property. The property has a farm exemption for this tank. Approximately 18- above -ground fuel tanks ranging in capacity from 400 to greater than 10,000 gallons exist on the site. Hand anger borings and exploratory borings (maximum depth of 42 feet bgs) were drilled in all seven areas. Groundwater was encountered in several of the borings at depths ranging from 35 feet to 42 feet, bgs. Perched water horizon was encountered in Boring B-2 at 9 feet Bgs. Groundwater gradient is inferred to f low to southwest. Localized metal concentration , specifically of cadmium and lead, are present at concentrations 10 times above STLC levels (Lead concentration of 68..2 PPM was detected in one of the soil samples in area B; STLC equivalent of 6.8, this is above the STLC level of 5 mg/L for lead ; one soil sample from area A yielded 482 PPM lead, STLC equivalent of 48.2 PPM exceeds the STLC value of 5 PPM) . 8-22--1991 Letter from attorney of the responsible party Mr. Rodney F. Lorang of Shenas, Shaw & Pievak Law Firm to RWQCB - San Diego Region. The letter states that the responsible party is. now preparing the Report of Waste Discharge for sandblasting grit deposited on the northern portion of the Davies Property. The letter also indicates that diesel oil and waste crankcase oil have been spilled on the northern portion of the Davies Property by various tenants and vendors (Total of 21 tenants). 10--3-1991 EPA's letter to responsible party (Vincent Davies) indicating that Vincent Davies Property north of the Otay River has been listed on EPA's inventory of potential hazardous 'substances sites. 10-4-1991.

The location of the test pits are Rshowm on attached Plate Number 2 entitled 'Test Location and Site Plot Plan'. ;ihe Pits are numbered 100, 101, and 102 to differentiate them from all previous explorations. The pits were logged and soil samples were obtained at the time that the pits were dug. These logs are presented on the attached Plates 3 through 5, inclusive. The location of the samples are indicated in both plan and profile. The contaminants of major concern consist of dense sand_b,lastin4 sand from the sand blasting of boat bottoms. This dense sand contains the residue of 'boat bottom paint which in turn contains significant amounts of heavy metals such as copper, lead; and zinc. - the soils encountered at the site were found to consist of assorted debris characteristics of a refuse disposal site for broken concrete, etc.. The deposits of blasting sand were easily ,identified. Actual quantities and concentrations of toxic metals from the blasting sand is difficult to determine without laboratory tests and the quantities and concentration of blasting sand in the fill ground is also difficult to determine. The placing of the blasting sand appears to be ,Is consistency of method or occurrence. The contaminated soil was found in a;thick and thin layers in the soil, large and small lense shape deposits, large nd small pockets, and deposits conforming to a slope created by end dumping over a Previous slope.

Exploration Pit lags #100 and #1101 contained high oncentrations of blasting sand. In Pit ##100, the sand occurs as a deposit on a re "aus slope whereby successive truck loads of material was `end dumped* over he face of the existing slope. The result was the creation of the stratus shown n the cross section on Plate 3. Usually, it would appear that approximately -.35.. percent of, the sn 15 .i n_ Pit. 4100" is cant tahated ;by, _4lastin'g .sand.

Some of that layers appear to be continuous while others are segmented. It appears that approximately 25 -to 40 per.cent;...o.f the :...so l:s -in Pit #101, are contaminated by the blasting sand and the sand deposits are not as well segregated from adjacent soils as those in Pit #100.

Closer investigation identified it as ashes.. - Native soils underlying the fill are comprised of sandy clays and clayey sands with very low permeability. The soil and debris that was found to be interlaced with the blasting sand is comprised of all soil types but were predominantly fine grained sail (clays or sandy clays) and construction debris that is a result of the demolition of roads and buildings and construction debris resulting from cleanup atter construction. Standard tests that were prescribed by the Water Quality Control Board were performed on the sand and adjacent soils by another laboratory acting as4. our subcontractor. Two sets of tests were performed. The first test method was denoted TT_ Test Method which we understand stands for Total Threshold Limit. The elements for which tests were performed was Caamtum, Chromium, CopPerii Lead,... - Zinc, ad,Zinc, and.;Arsenic. A second set of tests were run on the identical, samples using the STLC. Test Method (Saturated Threshold limit) which is a normal -realistic value for the leaching processes. The results of these tests are presented -on..-., attached Plate Number 6 entitled 'Results of Chemical Tests'. The chemical tests s: reveal that all. three pits contained deposits of blasting sand* although'Pit.." #102 was thought to contain little or no blasting sand.

This reveals that little or no leachin sand to adjacent sails. Page 6 PROJECT 4774 0S/13/86 SECTION 3. CONCLUSIONS The information afforded us by the extensive study and review of the elements listed under Section 2.1 has allowed us to draw the following conclusions regarding the dump site: it Contaminants do exist in the fill. They exist in the residual of boat bottom paint particles. The paint vehicle that carried and carry the particles has been designed to protect the contaminants from leaching into water. They have been designed for the specific purpose of prolonging the life and effectiveness of the bottom paint. 1 Standard tests performed to determine the presence of the hazardous material was conducted in %he pockets of blasting sand and also in the fill soil all around the known locations of the hazardous material. The tests show high concentration within the pockets of blasting sand but little or relatively none in the adjacent soil. As stated hereinbefore, no leaching has occurred in the past. Additional tests to determine the leaching potential of the concentrated areas as well as the adjacent soil were conducted. The additional tests show that the a leaching potential is very low. The existing fill soil contains large amounts of clay and it has very low i permeability. Moisture migration is toward the surface through a capillary process which is not a leaching process for the contaminants. The contaminants can leave the fill only as dissolved salts and then being transported by water migration. It is our opinion that the contaminants have not and will not leach to the ground water or migrate to the surface under the present conditions. We believe that the enhancement of the present condition (preventing water from leaching into and through the contaminated soil while allowing evaporation from the ground surface) will render the probability of the migration of the contaminants from the fill soil to be extremely remote. Any potential leaching can be monitored by observation wells placed adjacent to the contaminated portion of the dump site. This would insure that the leaching would be discovered soon after any leaching began and long after the level of toxins could be detrimental. Alternatives to the prevention of leaching into the environment is removal and - exportation of the contaminated fill to a dump site. This can be done in the-:..;:,..._:-. future if leaching of the contaminants are detected. or should land use and valuer--,- dictate. PROJECT 4774 08/13/86 SECTION 46. REC2MQDATIONS To prevent future leaching of detrimental substances into the environment, the following recommendations are made: I . Canstruction of an interceptor di;tch.up,slope :along -•the- proper t;� --- - line to intercept surface .runoff and divert i.t.- away from the contaminated fill. Slope the ditch to drain. Refer to the attached Plate Number 2 and Detail A on Plate Plumber 7.. 2. Gradethesurface . afi the contaminated pad to sheet dram tt�suai^ thecr_egk channel. Cap the surface with 6 inches of impermeable clay and a b inch protective blanket. Refer to Plate Plumber 2 and Detail B ' of Plate Number 7. i 3. ' Place t-bree--,-observations 'wells at the locations indicated on attached Plate number 2 and constructed as detailed on attached Plate Number S. The wells should be purged, sampled and tested after installed. After one week, they should be resampied and tested for a j' value to be used for future comparison. Thereafter, they should be sampled and tested on a six month schedule, preferably at the beginning and end of the rainy season. Test results should be submitted to the Water Quality Cantral Board. After a period of two years, the testing schedule should be re-evaluated. Page 8 `,.L LOCATION PLAN N 11-2000, Job Number: C.H.

Sherlock Sneil & W:;'lmer 1920 Main Street, Suite 1200 Imine, California 92614-7060 Dear Mr, Sherloclt: DENNERY RAND PROPERTY (PALM AVENUE &. OCEAN VIEW HILLS PARKWAY, SAN DIE(rC1) - MAL BORDER ZQNE PROPERTY DETERMINATION Gray Davis Governor This letter is in response to your request, on behalf of Pardee Construction Company (Pardee), far a border zone property determination for the Dcunmy Ranch property. The oubjoot site is lacated to the east of Interstate 805 and north of the intersection of Palm Avenue and (cean Views Hills Parkway, San Diego and is approximately 260 acres. This property is located within 2,000 feet of several hazardous waste disposal sites as well as having one potential hazardous waste disposal site located on a portion of the subject property itself. The subject property is proposed for residential development. The hazardous waste disposal sites located Within 2000 feet of the subject property include the former South Bay Refuse Disposal site, Apache ServiceslVincont Davies property and Omar Rendering. The former South Bay Rcfuse Disposal (South Bay) site, located to the southwest of the subject property to the southeast of the intersection of Palm Avenue with Interstate 805, was operated by the County of San Diego between 1951 and 1963. The South Bay site was granted site closure status by the County of San Diego Department of Enviro=u,,ntal Health (DEH), the San Diego Regional Water Quality Control Board (RWQCB), and the California Integrated Waste Management Board following final removal of all burn ash and associated soil in 1994. Apache Services, a former salvage yard, is located to the northwest of the subject property to the cast of Interstate 805 at 4551 Otay Valley Road. The site has been re -mediated and a "no further action" letter issued by DEH dated May 30, 1996, Omar Rendering, a former animal by-product processing plant, is located to the north of tl:c subject property at 4826 Otay Valley Road. A Class I landfill for liquid wastes was also operated on a portion of the site from 1959 to 1978, The landfill has been closed and post -closure ground water monitoring and sampling is being performed quarterly under the oversight of the R WQCB, the lead agency, pursuant to RWQCB Order No. 97-40. Although California Etviroamvara.l Protoodan Agcac^ Cb Priutcd on ilaoyrlcd Pepor Sean Sherlock September 15, 1999 Pe -e Two additional investigation is underway for the rcm inder of the site under RWQCfi oversight, the sits 445 btu to fenced and is located almost 2000 fest north of the subject site on the other side of the Otay River from the subject property, A health risk assessment for the site completed in 1996 concluded that there was no risk to off-site residents. A small portion. of the Denner} Ranch property, approximately 0.5 acres, contains burn ash material that appears to have originated at the former South Bay site. Pardee has signed a Voluntary Cleanup Agreement (VCA) with DTSC to evaluate this site and, if needed, remediate this portion of the subject property. This site ha -F been delineated in attachments to the VCA, :Exhibit 'A,' 4 legal description, and Pxhibit `$,a a map. Hoth of these documents have been included as attachments to this determination. Basad on a review of the existing infornaation, the Department of Toxic Substances Control (E)TSC) believes that the South Bay site, Apache ServicesfVineent Davies property and the Omar Rendering site will not pose a significant health threat to future residents of the Dennery Punch development. In its present state, the small portion of the Dennery Ranch that is the subject of the VCA will also not pose a significant health threat to future residents of the rest of the Dennery Ranch development. In the request .for a border zona property datermirAt on, Pardee has stated that they "will not build residential structure[s] on the area impacted by burn ash." A decision on the status of this small portion of the property will be rendered upon completion of the VCA. Thus, this decision is limited to ail of the rernaining Dennery Ranch property and not to the approximately 0.5 acre portion delineated in the attachments to this letter. Furthermore, this decision is limited surly to a review of the potential impacts from the South Hay site, Apache SeMcesNincent Davies property and the Lamar Rendering sits to the Dennery Ranch property. This decision is limited to the information disclosed to DTSC regarding the South Bay site, A.p4che StrviceslV'incerzt Davies property and the Omar Rendering Site. This decision should uM be construed to represent a fading regarding potential health or environmental risks from the Deanery Ranch property itself. Any other potential adverse environmental conditions that may be found on the Dennery Ranch property itself have not been disclosed, have not been reviewed or have not been made available to DTSC, Unless DTSC reviews environmental documents for the entire Dcnn,; y Ranch property, it has not and cannot make any funding regarding the Dennery Ranch Development itself.
