Twenty-three exploratory soil borings were drilled vertically using two truck- mounted drill rigs (B-61 and Failing 10) equipped with 8-inch-diameter, hollow-stem augers (HSA). Drilling equipment was supplied by H-F Drilling. Drilling activities were conducted on November 20 through 24, 1992. Boring locations were randomly seleaed in areas downgradient of potential contaminant sources. Exploratory soil borings were logged by an I HIA geologist according to the Unified Soil Classification System (USCS). The soil classification chart and key to HIA boring logs is presented on Plate Bl. HLA boring logs are presented on Plates B2 through B24. Soil samples were collected during drilling by driving a Sprague and Henwood (S&H) split- spoon sampler ahead of the auger at regular lO-foot-inten^als. Samples were retained in 6- inch-long, 2.5-inch-diameter stainless-steel tubes for field monitoring of organic vapors and for potential laboratory analysis. Monitoring of organic vapors was performed using a organic vapor analyzer (OVA), calibrated to methane. Typically, two samples per boring were selected for laboratory analysis based on OVA readings or as representative of specific soil types within the boring and of soils immediately above groundwater (if OVA readings were negligible). The selected soil samples were sealed with Teflon-lined caps, labeled, * placed in Ziploc bags, and stored in a cooler with ice for subsequent transport to National Environmental Testing, Inc. (NET), a State-certified testing laboratory, under chain-of- « custody protocol. —* Soil cuttings were stored in Department of Transportation-approved 55-gallon drums and left onsite in appropriate areas on the ROW pending receipt of laboratory analytical results, which will be used to evaluate disposal options. 92NCr020.ipt B-1 n Harding Lawson Associates 2.0 GROUNDWATER SAMPLING Groundwater sampling was performed in each of the soil borings, with the exception of Boring 18B-2, where groundwater was not encountered. The borings were drilled to 4 to 11 feet below the groundwater table, and then the hollow-stem auger was raised in the borehole to allow groundwater to flow into borehole fi-om the surrounding formation. Groundwater samples were collected with a clean, stainless-steel bailer, decanted into laboratory-prepared sample jars, capped, labeled, placed in Ziploc bags, and stored on ice for subsequent transport under chain-of-custody protocol to the State-certified laboratory for analysis. 92NCr020.ipt B-2 r PrinTRd on Recycled Paoer @ MAJOR DIVISIONS TYPICAL NAMES 2^ ^ in 08 OS I u I < ^ o y GRAVELS MORE THAN HALF COARSE FRACTION IS UkRSER THAN No. 4 SIEVE SIZE SANDS MORE THAN HALF COARSE FRAaiON IS SMALLER THAN No. 4 SIEVE SIZE GW wEa-CRAoeo GRAVELS, GRAVEL-SAND MXTURES CLEAN GRAVELS WITH UTILE OR NO FWES GP POORLY GRADED GRAVELS, GRAVEL-SAND MIXTURES GM SILTY GRAVELS.

DRAFT Harding Lawson Associates EXECUTIVE SUMMARY Harding Lawson Associates (HLA) has completed a Phase I Preliminaiy Site Assessment (PSA) for the Santa Fe Railroad Right-of-Way in San Diego County, Califomia. This assessment was authorized by Mr. Bedros Agopovich of Daniel, Mann, Johnson & Mendenhall, for the North County Transportation District (NCTD). HLA understands that the NCTTD is currently negotiadng the purchase of approximately 82 miles of railroad right- of-way (ROW) for the purpose of developing a light rail system. HLA has conducted a site history review, records review, field reconnaissance, and building assessment to identify potential areas of environmental concem along the ROW. From the 1930s to the present, sections of the agricultural and undeveloped land along the railway have been gradually replaced by residential, commercial, and industrial facilides; however large sections along the railway continue to be mral in nature. As a result of HLA*s PSA, several sites have been recommended for followup Phase II field investigations. 92DPR014.ipt vi Printed on Recycled Paper. DRAFT Harding Lawson Associates 1.0 INTRODUCTION This report presents the results of Harding Lawson Associates* (HLA) Phase I Preliminaiy Site Assessment (PSA) for the Santa Fe Railroad Right-of-Way (ROW) in San Diego County, Califomia (Plates 1 and 2). This PSA was authorized by Daniel, Mann, Johnson & Mendenhall for a proposed transaction regarding the subject property. HLA understands that the ROW in San Diego County consists of 82 miles of railway that is generally located in the following two areas: • San Diego Main Line (North San Diego County to downtown San Diego) Approximately 60 miles, and • Escondido Branch Line (Oceanside to Escondido) - Approximately 22 miles. The study area is defined as the area located within a 2,000-foot corridor of the ROW property. The purpose of this PSA is to provide information about the site and surrounding area relative to the potential presence of contamination on or beneath the subject site and/or study area due to previous or present usage of hazardous materials and/or wastes. This evaluation is based on information from historical aerial photographs, personal interviews with people familiar with the property, available documentation on the subject property and surrounding areas from Federal, State, and local agencies, and a reconnaissance of the subject site and study area conducted by HLA personnel. Track charts detailing the Santa Fe Mileposts (MP) for both the San Diego Main Line (MP 207.4 through 267) and the Escondido Branch Line (MP 0 through 21.3) were used to reference all environmental concems identified in this report to Santa Fe MPs. 92DPR014.ipt 1 Printed on Recycled Paper. DRAFT Harding Lawson Associates 2.0 SCOPE OF SERVICES To evaluate the potential impact of past or present usage of hazardous materials and/or wastes at the site and at adjacent properties, HLA conducted a Phase I PSA, which consisted of the following tasks: Task 1 - Site Historv Review - Review aerial photographs related to the historical development of the site and study area, - Review title search information as provided by the North County Transportation District (NCTD), - Contact City and County historical societies, and - Interview individuals who may be knowledgeable about the site and study area. • Task 2 - Records Review - Review and evaluate published regulatoiy agency lists of hazardous material sites within a 2,000-foot corridor of the ROW property, - Contact Federal, State, and local regulatory agencies for documented hazardous materials information conceming the site and study area, and - Review available agency information pertaining to the potential for contamination at the site and within the study area. • Task 3 - ROW and Adiacent Propertv Reconnaissance Conduct a visual reconnaissance of the ROW corridor and adjacent properties to corroborate indications of possible hazardous material contamination discovered in Tasks 1 and 2.

DRAFT Harding Lawson Associates 3.0 SITE DESCRIPTION 3.1 GENERAL The San Diego Main Line roughly parallels the southwest-facing coastline between the city of San Diego and the Orange/San Diego County line and is constmcted largely on a series of broad and level coastal terraces. These coastal terraces are cut by numerous westward-to southwestward-trending drainages for the highlands located northeast of the Main line. Generally, the railway appears to have been constmcted on existing ground surfaces and grades with a minimum of modification by grading. The Main Line crosses many historically active drainages, wash bottoms, and flood plains as it transverses northward from the City of San Diego to the north County line. At its southem end, the Main Line crosses the San Diego Flood Plain and the eastem flank of Mission Bay. From San Diego to Oceanside, the Main Line crosses several large drainages including the San Diego River, Soledad Canyon, and San Dieguito River. In addition, the railway traverses the mouths of Batiguitos, Buena Vista, and San Eligo Lagoons leading to the sea. The central portion of the Main Line at Oceanside and the Escondido Branch Line are located within or on the margin of the Loma Alta Creek drainage. North of Oceanside to the north County line, the Main Line crosses the extensive drainages associated with Pilgrim Creek, Santa Margarita River, and Aliso, Las Pulgas, San Onofre, and San Marco Canyons. Based on the U.S. Geological Survey (USGS) 7.5-minute series topographic maps, the Main Line varies in elevation from approximately 20 feet above mean sea level (MSL) at drainage crossings (i.e., Oceanside) to approximately 374 feet above MSL in the Rose Canyon - La Jolla Mesa area. A maximum elevation of approximately 690 feet above MSL is reached by the Escondido Branch Line approximately 2 miles west of Escondido. 3.2 GEOLOGY The San Diego Main Line and the Escondido Branch Line are located within the southwestem portion of the Peninsular Range Province of Califomia. The railway is located 92DPR014.ipt 4 QW Printed on Recycled Paper. DRAFT Harding Lawson Associates on the southwestem flank of a westward-tilted, northwestward trending stmctural block bounded on the northeast by the Elsinore Valley fault zone and on the southwest by the Newport-Inglewood and Rose Canyon fault zones. On the southwestem side of this stmctural block extending from the County line to the city of San Diego, numerous prominent wave-cut (Pliestocene age) marine terraces extend inland for several miles, especially along the northem portion of the railway (north of Oceanside). The marine terrace features are cut by younger southwest- to westward-trending drainages, which have been partially infilled to unknown depths with either old (Pleistocene-age) alluvial deposits, forming nonmarine terraces, and/or recent (Holocene-age) alluvial deposits. The entire Main Line, especially the section north of Oceanside, crosses extensive marine terrace deposits generally composed of a crudely semi-consolidated stratified muture of sand, silt, and clay with scattered gravel, cobbles and boulders unconformably overlying bedrock units (Hunt and Hawkins, 1975). The railway also crosses several drainages that cut these marine terraces deposits. Concentrated along the drainages are older alluvium (nonmarine terraces), recent alluvium, slopewash, and beach deposits. In general these deposits consist of mixtures of poorly consolidated silt, sand, gravel, cobbles, and boulders. The alluvial materials appear to be thickest in the larger drainages of San Mateo, San Onofre, Las Puigas, San Margarita, San Luis Rey, Escondido Osuna, Soledad, and San Diego Canyons and Agua Hediondo, Buena Vista, and Batiquitos Lagoons. From the north County line to Oceanside, the Main Line crosses predominantly surficial deposits (i.e. marine terrace deposits); however, locally along the margins of drainages crossed by the railway minor exposures of Pleistocene to Pliocene San Mateo Formation bedrock are reported by Hunt and Hawkins (1975). The San Mateo Formadon chiefly consists of consolidated massive arkosic sandstone with scattered interbeds of gravel silty sandstone and siltstone. As determined from Rogers (1985) and Straud (1977), south of Oceanside to the city of San Diego, the Main Line encounters larger amounts of bedrock because of the more complete erosion of the coastal marine terraces. Bedrock beneath the eroded marine terraces and other surficial deposits for this portion ofthe railway consist of Eocene-age marine sediments WDPR014.ipt 5 Printed on Recycled Paper. Harding lawson Associates of the Poway Group overlying the La Jolla Group. The Poway and La Jolla Groups, as defined by the Califomia Division of Mines and Geology (CDMG) (Kennedy, 1975), contain several complexely interfingering rock units of conglomerate, sandstone, shale, and claystone representing two periods of past marine transgression followed by subsequent marine regressions. The Poway Group is composed of the Mission Valley (predominantly a sandstone)- Pomerado Conglomerate and the Stadium Conglomerate Formations in order of increasing age. The La Jolla Group is composed of the Friars (sandstone and claystone), Scripps (sandstone with conglomerate interbeds) Ardath Shale, Torrey Sandstone, and Del Mar (sandy claystone with sandstone interbeds) Formations. The Escondido Branch Line is predominantly underlain by bedrock. Based on information by Rogers (1985), the Branch Line starts in Oceanside on thick alluvial deposits, but the alluvium thins toward the east, and bedrock becomes the prime foundation material. Generally, the bedrock units become progressively older from west to east along the Branch Line. Limited amounts of San Mateo Formation, and extensive exposures of the Poway and La Jolla Groups are encountered east of El Camino Real to approximately Highway 78. East of Highway 78, the Branch Line is on Mesozoic-age granitics of the Southem Califomia Batholith, which was intmded into upper Jurassic-age metavolcanics of the Santiago Peak Volcanics and metasedimentaiy rock of the Jurassic-age Bedford Canyon Formation. Based on a review of the available literature, the Main Line crosses two well documented fault zones identified as the Cristianitos and Rose Canyon fault zones. The Main Line crosses the Cristianitos fault zone approximately 1/2 mile south of the San Onofre Nuclear Power Generator Station. The Cristianitos fault zone was extensively investigated as part of the constmction of the power plant and was determined to be inactive (this section of the fault has not moved during the last 11,000 years). From approximately La Jolla southward to the end of the Main Line in the City of San Diego, the railway closely parallels (within 1/2 mile) or is within the Rose Canyon fault zone. This zone composed of several different faults with differing names. The Rose Canyon Fault zone is defined as a potentially active fault zone, meaning that the fault zone exhibits evidence of movement within the last 2 million years (Hart, 1985) and is identified by the CDMG (Reiche, 1990) as probably the most hazardous fault zone within the San Diego metropolitan area. 92DPR014.ipt 6 \W Printed on Recycled Paper. DRAFT Harding Lawson Associates 3J HYDROGEOLOGY The railway is located within the San Diego Groundwater Basin as defined by the State Department of Water Resources and the Califomia Regional Water Quality Control Board, San Diego Region (DWR, 1975b). Because of the length of the railway, the alignment crosses several hydrographic units of the San Diego Groundwater Basin. These hydrographic units have been further subdivided by the RWQCB into subunits (and associated groundwater basins). A list of these hydrographic units and subunits is provided in Table 1. Sixteen groundwater basins are present in the coastal area beneath the railway. These basins consist generally of valleys infilled with poorly consolidated Holocene alluvium and semi- consolidated and consolidated Quatemary to Tertiaiy nearshore marine and nonmarine water-bearing sedimentaiy deposits. The coastal area traversed by the railway contains no large groundwater basins. Six of the basins range in area from 5 to 6.6 square miles (mi^), and the others range from 0.37 to 3.6 mil Four of the basins, the San Mateo, San Onofre Valley, San Luis Rey Mission Valley, and San Dieguito, are capable of storing approximately 322,100 acre-feet of groundwater in the upper sediments. The usable storage capacity as estimated by the DWR in 1967 is approximately 102,500 acre-feet per basin. In addition to the 16 groundwater basins, shallow marine tertace deposits located along the entire coastline and beneath portions of the San Diego Main Line may also store groundwater (DWR, 1975b). Groundwater flow directions and gradients vary along the railway alignment; however, a few general trends appear to exist. Groundwater levels appear to dip uniformly west- southwestward toward the Pacific Ocean, essentially paralleling and flowing in valley-bottom washes. Groundwater levels can range from nearly 350 feet above MSL in the highland east of the railway (i.e., the eastem portion of the Agua Hedionda Basin [DWR,*1988]) to 3 feet below MSL as recorded in Oceanside in 1952 (i.e.. Well 11S/SW-02N04). According to the DWR (1975a), seawater intmsion is known to have occurred in the San Luis Rey Valley groundwater basin and is suspected in the San Diego River Valley. In areas of seawater intmsion, the gradient may be locally reversed, dipping eastward toward land. 92DPR014.ipt P Printed on Recycled Paper, DKAM Harding Lawson Associates At approximately MP 253 on the San Diego Main Line, groundwater flow direction varies from the typical west-southwest trend where it is split by a shallow east-west trending groundwater divide. In this area, groundwater flow north of the divide is to the northwest along Soledad Canyon, and south of the divide it is to the southwest along Rose Canyon. Groundwater condidons along the southem and northem ends of the San Diego Main Line are increasingly complicated by the presence of the Cristianitos and Rose Canyon faults, respectively, which may produce groundwater barriers impounding groundwater on the east side of the fault zones. Groundwater quality data indicate that the character of the groundwater for each subarea is predominantly that of sodium chloride with lesser amounts of sulfates and nitrates. Total dissolved solids (TDS) concentrations range from 250 to greater than 5,000 parts per million with the highest TOS concentrations found in the San Luis Rey and San Dieguito River areas. These high TOS concentrations may be related to seawater intmsion. Groundwater quality ranges from suitable to inferior for domestic and irrigation uses along the length of the railway. 92DPR014.ipt F Printed on Recycled Paper. 79. DRAFT Harding Lawson Associates 4.0 SITE HISTORY REVIEW 4.1 VERBAL AND WRITTEN HISTORY HLA personnel interviewed Mr. Jerry Nebben of the NCTD on August 3,1992. Mr. Nebben stated that the town of Agra has historically been used as a staging area for chemicals used for agricultural purposes in northern San Diego County. Mr. Greg Thorpe, an attomey for the NCTO, was also interviewed by HLA personnel on August 3,1992. He stated that he had read that a small, gasoline powered, shuttle train, called "Doodle Bugs", operated along the Santa Fe line in thc 1930s and/or 1940s. He said that gasoline storage tanks supported the train along the line. HLA was unable to confirm this information. On August 1,1992, HLA personnel spoke with a librarian at the Historical Society of San Diego and were referred to the Museum of San Diego Histoiy at Balboa Park. The archivist at the museum stated that they had photographs of the trains, but most of their written information was on the railway that ran from San Diego to Arizona. HLA personnel also reviewed title information for the subject property as supplied by the NCTO. NCTO supplied station maps of the railway that show who leased, bought, or contracted to use land adjacent to the railroad tracks from the Orange County line to the city of San Diego including the Escondido Branch Line. Additionally, the maps show the lease dates, utility easements, names of lease holders, railroad equipment, and Santa Fe MPs. Lease dates range from 1899 to 1984. Information listed conceming adjacent property owners does not include much significant documentation about usage of adjacent land; however, the following properties that were either identified in the records review or that appeared to be of environmental concem based on the business name.

In addition, current aerial photographs of the site were supplied by the NCTO. Aerial photographs of the Main Line were reviewed for flights for the years 1932,1937,1939, 1941,1946,1953,1969,1972,1973,1977,1978,1979, and 1990. For the Escondido Branch Line, photographs were reviewed for flights for the years 1937,1939,1952,1972,1973, and 1979. Most flights covered only portions of the railway under review. - Pertinent USGS maps of the railway were reviewed and divided into 1-mile sections beginning at the Orange/San Diego County boundary and preceding south (MP 207.4 to 267). The Escondido Branch Line was divided into 1 mile sections in a similar manner starting in South Oceanside and proceeding east (MP 0 to 21.3). By correlating landmarks, railway and road configurations, and topography on the USGS maps and aerial photographs, the land uses and historical development along the 1/4-mile corridor were investigated on a mile-by-mile basis. Information gained from the site history review was used to guide the field reconnaissance of the ROW and adjacent properties.

Although locations of the environmental concems observed were correlated with MPs, these locations should be considered approximate because many of the photographs were taken from a high altitude and because of the sometimes large distance between easily identifiable landmarks. 4.2.1 San Diego Main Line Aerial photographs from the 1930s indicate that the railway and 1/4-mile-wide corridor were predominantly undeveloped or sparsely occupied by agricultural fields, cides, residences, commercial facilities, or light industrial facilities. From the 1930s to the present, sections of the agricultural and undeveloped land have been gradually replaced by residential, commercial and industrial facilities; however, large sections ofthe ROW condnue to be mral in nature. For Plate la historical photographs from 1932 through the late 1970s were reviewed. For Plates lb through lh, photographs from 1932 to 1990 were reviewed. Photographs from 1941 through 1990 were reviewed for Plate li. For Plates lj through 11, photographs from 1972, 1979, and 1990 were reviewed. MPs 262 and 263 at the northern end of Plate lm included reviews of photographs from 1972, 1978, and 1990, but only included reviews of photographs from 1972 and/or 1979 for MPs 264 and 265. Aerial photographs from 1979 were reviewed for MP 266 on Plate In. Plate la covers the railway from MP 207.4 to 223, which has historically included large sections of agricultural fields and undeveloped land (MP 207.4, 208, 211 through 214, 216 through 219, 221, and 222). Agricultural and undeveloped land were present in Mile 210 until 1972 when constmction activities for the San Onofre power plant became visible. Several aboveground storage tanks (ASTs), large storage areas, and two large holding ponds were observed in Mile 210. At Miles 215,220, and 223, maintenance areas were present in the 1932 aerial photographs, that were not distinguishable in photograph from later years. In 1939, Camp Del Mar, which contained several ASTs and storage areas on both sides of the tracks, is present at Miie 223. The number ofbuildings and storage areas associated with this facility increased until the 1950s and appeared to decrease thereafter. 92DPR014.ipt 11 Printed on Recycled Paper. DRAFT Harding Lawson Associates Plate lb includes MP 225 through 226. The city of Oceanside is present in all of the photographs reviewed of this area. The agricultural and undeveloped land surtounding Oceanside is gradually replaced with commercial/industrial and residendal development in later years. In Mile 225, evidence of drum storage and staining is visible on a set of sidetracks located east of the main tracks in the 1990 photographs reviewed. As early as 1932, a spur was observed in Mile 226 that leaves the main track and mns along approximately 10 large commercial/industrial facilities with ASTs and storage areas. In the 1990 photographs of Mile 226, several sites with significant staining, evidence of storage of dmms and materials, and ASTs are adjacent to the tracks and spur. The Escondido junction is present in the 1932 photograph of Mile 227. Soil staining is visible at this junction. Plate lc includes MPs 228 through 230.

Historical photographs were reviewed for this location only for the year 1979. Heavy industrial and commercial facilities were observed on both sides of the railway. 4.2.2 Escondido Branch Line The aerial photographs indicate that the Escondido Branch Line and the 1/4-mile corridor historically were primarily occupied by undeveloped land and agricultural fields, and sparsely occupied by cities, residences, commercial facilities, or light industrial facilities. From the 1930s to the present, sections of the agricultural and undeveloped land have been gradually replaced by residential, commercial, and industrial facilities. Plate 2a covers the MP 0 through 2. (The Escondido Junction is described as part of the Main Line) The surrounding area has historically been residential, agricultural, and undeveloped land. In 1952, at the beginning of MP 1, some staining was visible along the tracks, but by 1973 is not visible. Also in 1952, a small airfield is present north of the tracks and has some staining adjacent to the buildings. In the 1979 photograph, the airfield is improved and the stains are no longer visible. MP 2 in 1937 was all agricultural and undeveloped land. In the 1952 photograph, a silica mine is located south of the tracks. In subsequent years the mine extends further west, and stmctures are visible next to the tracks. Plate 2b includes MP 3 through 5, The silica mine is visible on the northem portion of MP 3 from 1937 to the present. In 1952 there is visible staining on the tracks, and a storage area is located to the north. MP 4 is consists of undeveloped land from 1937 to the present. From 1937 until 1952, MP 5 is all undeveloped land; in 1979 scattered residential stmctures are visible along the tracks. Plate 2c includes MP 6 through 9. In 1972 the land around the tracks is undeveloped land. One area of concem in the middle of Mile 6, south of the tracks is an apparent landfill with 92DPR014.rpl 14 Cw Printed on Recycled Paper. DRAFT Harding Lawson Associates an open pit that appears to contain a liquid. By 1979 the pit area is no longer visible. MP 7 is a mbcture of undeveloped land with some residential and commercial buildings. MPs 7 and 8 are mostly commercial and residential next to the tracks. For all photographs reviewed, there is a quany near the town of Vista and in 1979 a dmm storage yard visible to the south in the town of Vista, adjacent to the south side of the tracks. Plate 2d encompasses MP 10 through 13. From 1939 (1972 for MP 10) to the present, the tracks are flanked by agricultural land with residential, commercial, and industrial buildings. In 1973 at MP 10, a storage yard with visible stains is adjacent to the tracks. Plate 2e includes MP 14 through 16. The area is mainly residential with some agricultural fields and a few commercial stmctures from 1939 to 1979. A gravel pit is visible north of the tracks at MP 1 in 1972. In 1979, there appears to be a landfill on the south side of the tracks, and an auto junkyard to the north. Plate 2f includes MP 17 through 19. In 1939, the tracks are flanked by agricultural fields. From 1972-73 to 1979, there is in a gradual increase in residential, commercial, and industrial buildings. Plate 2g contains MP 20 and 21. Since 1973, the city of Escondido has been primarily a mucture of residential and commercial buildings.

Regulatoiy agency information was obtained from Govemment Records Reports compiled by Vista Environmental Information, Inc. (Vista) of San Diego, Califomia. Additional information was obtained by contacting local. State, and Federal environmental enforcement agencies. 5.1 REVIEW OF PUBLISHED REGULATORY AGENCY LISTS As part of this assessment, HLA obtained Govemment Records Reports prepared by Vista to evaluate whether sources on or near the ROW property may potentially pose an environmental threat to the ROW property. Vista provided separate reports for the Main Line from north San Diego County to downtown San Diego and the Branch Line from Escondido to Oceanside. Vista's search of govemment database sources was limited to a 2,000-foot corridor along the ROW property. Vista's search identified over 300 sites within the 2,000-foot corridor that appeared on at least one of the regulatoiy agency lists. HLA reviewed and evaluated Vista's reports in order to create a list of sites that may impact the ROW property based on the sites' proximity to the rail line and/or their upgradient locadon with respect to groundwater flow direction. The sites of concem identified by HLA are summarized in Table 2 (San Diego Line) and Table 3 (Escondido Line) and shown on Plates la through In and Plates 2a through 2g, respeaively. These tables identify each site by name, address, map number, mile marker number, and Vista's own identification number. Several of these sites appear on multiple regulatory agency lists; Tables 2 and 3 summarize the lists in which each site appears. HLA is in the process of obtaining additional information on each of these sites from the appropriate regulatory agencies in order to evaluate their potential to impact the ROW. Additionally, HLA reviewed the most recently available version of the United States Environmental Protection Agency (EPA), Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS), and National Priorities List 92DPR014.ipt 16 F Printed on Recycled Paper. DRAFT Harding Lawson Associates (NPL) in order to identify listed sites within 5 miles of the ROW property as specified in HLA's proposal dated June 23,1992. The discussion presented in this section is based on available information provided by the following govemment agencies and lists. The entire Vista report covering the 2,000-foot corridor along the ROW property is included in Appendbc B. • EPA Comprehensive Environmental Response, Compensation, and Liability Information System January 9, 1992 - CERCLIS provides information for businesses or properties that are in or being considered for the Federal Superfund Program according to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). Under this program, a business or property is identified, and a preliminary assessment is performed to assess whether the site shall become a Federal Superfund site. CERCLIS sites of concem identified within the l,0(X)-foot corridor for the San Diego Line and the Escondido Line are presented in Appendbc E. Appendbc E also lists additional CERCLIS sites within 5 miles of the ROW property. Additional information was obtained from the EPA on several sites with close proximity to the ROW and/or in an upgradient locadon with respect to groundwater flow direction. A summary of this information follows: - Burroughs Corporation. 5600 Avenida Encinas. Carlsbad - In 1974, Burroughs began manufacturing operations involving the design, processing, and manufacture of computer boards for other Burroughs facilides. The electroplating operations produced up to 35,000-gallons-per-day of acidic wastes containing copper, zinc, nickel, and chromium. Additionally, 2,000 tons of copper/fiber board dust and 50 tons of solid acidic and solvent wastes was annually disposed of at an unspecified Class I landfill. The facility constmcted two 500,000-gallon storage ponds for process wastewater evaporation; both ponds were lined with an acid-resistant material. In 1980, the Regional Water Quality Control Board (RWQCB) was notified that one of the pond liners had failed, allowing an undetermined amount of wastewater to leak into the underlying soil. Subsequently, 1,640 tons of contaminated soil (copper concentrations exceeding 100 ppm) was removed, along with the liner, and taken to the BKK Class I landfill in West Covina, Califomia. Groundwater at 6 to 8 feet below ground surface was removed in order to reduce the copper level in groundwater to less than 10 parts per million (ppm). In 1981, a discharge of solvent caused a second leak in the same pond. Clean water was flushed through the contaminated soil, and the pond was subsequently filled in with clean soil. The second pond was closed after inspection and authorization by the RWQCB in 1983 following a reduction in 92DPR014.ipl 17 Cw Printed on Recycled Paper. DRAFT Harding Lawson Associates Burroughs' manufacturing operations. The Califomia Department of Health Services approved Burroughs' closure plan for its facility in 1987. Groundwater within 3 miles of the Burroughs site is not used for drinking or irrigation purposes, and surface water within 3 miles of the site consists of the Pacific Ocean and the Agua Hedionda Lagoon, a wildlife habitat. A release of hazardous wastes from the site through the air is unlikely, since contaminated soil has been removed from surface impoundments, and the impoundments have been filled with clean soil. No further action is recommended for this site. No site maps were provided with this reassessment summaiy that would indicate the location of the referenced ponds or other Burtoughs facilities with respect to the ROW property. - Naval Training Center (Marine Corps Recmit Depots San Diego - A Federal Facility Preliminary Assessment Review (October 31, 1991) states that an Initial Assessment Study (IAS) prepared for the Naval Training Center (NTC) contained site information for the adjacent Marine Corps Recmit Depot (MCRD). The Old MCRD disposal area is located on property transferred to NTC from MCRD in 1975. MCRD operated a 32-acre, municipal-type landfill from the late 1940s to 1971 on filled marsh located between San Diego Intemationai Airport and the Boat Channel west of the airport. The disposal area received primarily municipal refuse from the NTC and MCRD but also accepted infectious wastes, paint wastes, empty pesticide containers, surplus pesticides, wood treatment chemicals (pentachlorophenol), waste motor oils, solvents, gasoline, paint thinners, and some pladng wastes. Transformers containing dielectric fluids were also disposed of at this site, but no specific information was available as to whether the transformers disposed of at the site contained PCBs. The IAS estimates that between 12,000 and 19,000 gallons of wastes were deposited at the old MCRD disposal area; however, the preliminary assessment states that information presented implies that a larger quantity of waste was disposed of at this site. It is believed that wastes deposited at this site may be in hydraulic connection with shallow groundwater which may in turn flow into the San Diego Bay. This site may also have areas of soil contamination; however, sampling had not been conducted as of the date of the preliminary assessment. This site is classified as high priority for further assessment. - General Dynamics. Convair Division. 3302 Pacific Highwav. San Diego - The preliminary assessment summary prepared in 1985 states that General Dynamics has manufactured aerospace products at this site since 1935. Convair is one of several divisions within the complex. Hazardous waste is generated in three main areas within the division: (1) Building 1 has an electroplating process, acid etching, alkaline cleaning, and a vapor degreaser; (2) Building 3 has an unspecified chemical processing operation and phosphoric acid anodizing; and (3) Building 75 has a large (unspecified) chemical processing operation. Wastes generated include acid and alkaline 92DPR014jpt 18 Cw Primed on Recycled Paper. DKAFi Harding Lawson Associates liquids, oily water, solvents, oils, paint waste, hazardous waste solids, asbestos, and PCBs. The wastes are stored in drums or tanks; the solvents and oils are recycled while the other wastes are disposed of offsite. EPA staff recommends no further action on this site based on the fact that past spills have been minor and mainly to the sewer and that there is no documented evidence of disposal of hazardous wastes on the site. No site maps were provided with this preliminary assessment summaiy that would indicate the location of the referenced buildings with respect to the ROW property. • EPA National Priorities List for Uncontrolled Hazardous Waste Sites, January 23,1992 - The NPL is a listing of CERCLIS sites which have been determined by EPA's Hazard Ranking System to present the greatest potential risks to human health and the environment. NPL sites, also known as Superfund sites, are qualified to receive CERCLA remedial funding. The only NPL site within the 5-mile study area is the Camp Pendleton Marine Corps Base (Camp Pendleton). The San Diego rail line crosses Camp Pendleton in a north-south direction across the western portion of the base. The information available on this site is presented below under the description of the CAL-SITES Annual Work Plan. Additional information on Camp Pendleton will be obtained by HLA from the California Department of Toxic Substances Control (DTSC) as soon as the information becomes available. • EPA Federal Superfund Liens, September 11,1991 - The SEPA has authority to file a lien against real property to recover clean up, response, and any other expenditure made by EPA under CERCLA. EPA prepares a listing of filed notices of Superfund liens, which is updated quarterly. There are no sites within the study area on the Superfund Liens list. • Hazardous Waste and Substance List (Cortese List), November 1990 - The Cortese List is compiled annually by the Califomia Govemor's Office ofPlanning and Research and provides information conceming potential and confirmed hazardous waste sites within the State of Califomia.

All sites on the Cortese List are also listed by the RWQCB and/or County Environmental Health Department (EHD); descriptions of the current status of these sites can be found in the RWQCB and/or EHD sections below. • CAL-SITES Annual Work Plan (AWP), October 31,1991 - The AWP contains a listing of all verified hazardous waste sites that are or will be targeted for cleanup by the Califomia Environmental Protection Agency (CAL-EPA) under the Hazardous Substance Cleanup Bond Act of 1984 and the Hazardous Substance Account (HSA). 92DPR014.ipt 19 Cw Printed on Recycled Paper. DKAFi Harding Lawson Associates There are no sites within the Escondido Line's 2,000-foot corridor on the AWP. There are two sites within the San Diego Line's 2,000-foot corridor on the AWP: Miramar Naval Air Station and Camp Pendleton Marine Corps Base. The available information on the status of these sites is presented below. Additional information on Camp Pendleton and Miramar Naval Air Station will be obtained by HLA from the California Department of Toxic Substances Control as soon as it becomes available. - Miramar Naval Air Station - The summaiy of the Federal Facility Cleanup Workplan included in the 1989 Bond Expenditure Plan states that a total of 10 potentially contaminated areas were identified at this site. The history of waste disposal indicates that oils, mbced solvents, paints, paint thinners, and waste fuels have been improperly disposed of at the facility. According to the initial assessment study, none of the areas pose immediate threats to human health or the environment; but five of the areas warrant further investigation to determine the extent of contamination and necessity of performing mitigating actions and/or cleanup operations. Surface water migration and direct contact are the primary concems. At the time this summary was prepared for the Bond Expenditure Plan, an installation restoration program had been initiated at the base, and the program was in the initial (preliminary) assessment phase of the mitigation process. - Camp Pendleton Marine Corps Training Camp - The summary of the Federal Facility Cleanup Workplan included in the 1989 Bond Expenditure Plan states that five sites on the base warrant further investigation according to studies conducted by the U.S. Navy. These sites include a waste pesticide wash rack, air operations drainage ditch, bum pits in a fire fighter drill field, a scrap yard, and a hazardous waste landfill. Soils are potentially contaminated with gasoline products, solvents, and heavy metals in areas identified by the U.S. Navy. The landfill may contain asbestos, ordnance, hospital wastes, PCBs, waste pesticides and herbicides, and pentachlorophenol. There is a high probability of contaminant migration into soil, surface waters, and groundwater beneath and adjacent to the facility. Additionally, there is a potential for direct contact with contaminated soils by workers onsite. Groundwater is a potential source of drinking water for the area. At the time this summaiy was prepared for the Bond Expenditure Plan, an installation restoration program had been initiated at the base by the U.S. Department of Defense, and contaminated areas on the base were being identified under this program. Border Zone Properties Act Sites (Deed Restrictions), February 1, 1992 - Pursuant to the Hazardous Waste Property/Border Zone Property Law, the CAL- EPA, DTSC is authorized to enter into voluntary deed restriction agreements with property owners who propose constmction of residences, schools, hospital, or daycare centers on properties that are "on or within 2,000 feet of a significant disposal of hazardous waste."

The DTSC has also interviewed county and local agency officials and reviewed the records of the RWQCB, Department of Fish and Game, other State environmental regulatory agencies, and historical land use data sources to generate lists of potential sites. Information conceming most of these sites should be considered preliminary, although most confirmed sites from this database are merged into the AWP database once they have been priority ranked. Many of these sites are currently identified as requiring no further action (NFA) based on DTSC determination that no release had occurred or, if a release may have occurred, it did not represent a significant threat to the public or the environment. Appendix E lists the CAL-SITES identified within the study area for the San Diego and the Escondido Lines along with additional information on these sites provided by DTSC. • DTSC Hazardous Waste Information System (HWIS), September 30, 1991 • DTSC has developed and maintains lists of hazardous waste generators and hazardous waste treatment, storage, and disposal facilities in Califomia.

No completed wells were shown on the map that are currently producing oil and/or gas, and no completed abandoned wells were shown. • San Diego County Agricultural Commission - HLA contacted the San Diego County Agricultural Commission regarding pesticide use, storage, or releases along the ROW property. HLA also requested any available information on three sites historically used for pesticide loading along the ROW, Agra, Los Flores, and Stuart. Mr. Dick Waldrip of the Agricultural Commission indicated that he believed these stations to be on property that is now occupied by Camp Pendleton. He was not aware of any major spills or any loading/unloading of 92DPR014.ipt 22 Qw Printed on Recycled Paper. DRAFT Harding Lawson Associates pesticides since 1963. He was able to give us information verbally on two minor incidents along the rail line. The first was in 1978 to 1980 when a Santa Fe rail car used to spray weeds along the ROW leaked herbicide at the Oceanside Railyard (north of Oceanside). Mr. Waldrip was unable to provide HLA with any exact information regarding quantities released or remedial activities. The second incident was a fire at a shed containing dmms of soil fiimigant in 1985 to 1987. This incident occurred approximately 5 miles north of Oceanside adjacent to the rail line. Mr. Waldrip was unable to provide HLA with any exact information regarding quantities released or remedial activities associated with this incident. Califomia Department ofTransportation (CalTrans) - HLA contacted CalTrans regarding past hazardous materials releases along the ROW property. Mr. Lany Croner of CalTrans stated that there were no releases on record for the last 3 years and that there were no good records kept prior to that time. In the 6 years, he had been with CalTrans, he could not recall any hazardous materials incidents along the ROW. Mr. Bob Rowland of CalTrans was also unaware of any hazardous materials incidents along the ROW in recent years. HLA was unable to find any additional information regarding past hazardous material releases along the ROW. 92DPR014.fpt 23 ^Printed on Recycled Paper. DRAFT Harding Lawson Associates 6.0 FIELD INVESTIGATION AND nNDINGS From September 3 through 11,1992, HLA personnel investigated both the ROW and study area, defined as a 2,000-foot corridor along the San Diego Main Line and the Escondido Branch Line. 6.1 METHODOLOGY An inspection was conducted by HLA personnel to assess the potential for current conditions, tenants, and activities in the ROW and study area to environmentally impact the surface and subsurface at the subject site. Mr. Ben Jones, flagman for Santa Fe Railroad, escorted HLA personnel during the inspection of the Main Line ROW. HLA personnel were not accompanied by Santa Fe Railroad personnel during the inspection of the Branch Line ROW or during the characterization of the study area. The study area was visually inspected by driving alongside the railway or, in areas inaccessible to HLA and Santa Fe Railroad vehicles (i.e., wetlands, bays, and canyons), was visually inspected from observation points using high-power binoculars. The study area was visually inspected for potential environmental concems including the presence of USTs, ASTs, pits, clarifiers, sumps, hazardous materials/waste storage areas, unusual stains or odors, hazardous materials/waste spills, and evidence of public dumping. Additionally, HLA personnel reviewed information collected during Tasks 1 and 2 of this assessment to identify known sources of contamination that may have the potential to threaten the environmental condition of the subsurface geology of the subject site. Areas of concem identified during Tasks 1 and 2 were inspected from points of public access or from the ROW. 6.2 MAINLINE The Main Line consists of Santa Fe Railroad Miles 207 through 267. The Main Line begins at the Orange County/San Diego County border and travels through Camp Pendleton and the communities of Oceanside, Carlsbad, Encinitas, Solano Beach, Del Mar, Soledad Valley, 92DPR014.ipt 24 Primed on Recycled Paper. /^ | DRAFT Harding Lawson Associates La Jolla, and San Diego. Areas of the Main Line pass wetlands, dense natural vegetation, heavy industry, light industry, commercial centers, military facilities, agricultural fields, and power stations. The location and a brief description of the level of environmental concem for each site identified during the site inspection is illustrated on Maps 3a-3n. In the following summary of findings, all sites are described as either being on the west or east side of the railway. Through Soledad Valley, sites located north or south of the track are described as being east or west of the track, respectively. Photographs taken during the site visit are presented in Appendbc C. 6.2.1 Plate 3a Plate 3a identifies sites located within a 2,000-foot corridor of Miles 207 through 223. Mile 207 and 208 San Onofre State Beach is located west of the railroad. Natural vegetation and the Interstate 5 (1-5) freeway are located east of the railroad. HLA identified no sites of environmental interest in Miles 207 or 208. Mile 209 San Onofre State Beach recreational facility and San Onofre Nuclear Power Plant are located west of the railroad. Natural vegetation, 1-5, and Camp Pendleton are located east of the railroad. HLA identified two sites of environmental interest located in Mile 209: Areas of Camp Pendleton located within the 2,000-foot corridor consisted of natural vegetation only. It is unlikely that this portion of Camp Pendleton poses an environmental threat to the railway. Hazardous materials use and storage, possible hazardous waste generation, spillage, and soil stains were observed in several areas at thc San Diego Gas and Electric (SDGE) San Onofre Nuclear Power Plant, including a maintenance facility located within 100 feet of the railroad. The environmental threat posed by this site is considered to be high. 92DPR014.ipt 25 ^ Printed on Recycled Paper.

Below is a list of definitions for these qualifiers or "flags". 1. Blank Space: A blank space in the "Q" column signifies an analyte was detected at a level which was within the acceptable calibration range for the method. 2. U: Indicates compound was analjrzed for but not detected. 3. J: This flag is used when the data indicate the presence of a compound that meets the identification critena but the result is less than the sample quantitation limit and greater than zero. For example, if the sample quantitation limit is 10 ug/kg, but a concentration of 3 u^g is calculated, it is reported as 3J. 4. E: This flag identifies compounds whose concentrations exceed the calibration range of the instrument for that specific analysis. Such samples are diluted and rerun in order to bring the detection(s) within the calibration range. 5. B: This flag is used when the analyte is found in the associated blank as well as in the sample. It indicates possible/probable blank contamination and warns the data user to take appropriate action. I Printed on Recycled Paper.
