EXECUTIVE SUMMARY ___________________________________________________________________________________ This Phase I Environmental Site Assessment (Phase I ESA) of the property located at 3580 Bullock Lane in the City of San Luis Obispo, California (the Site) was performed by Haro Environmental for Bullock Ranch, LLC. Haro Environmental performed this Phase I ESA consistent with the American Society for Testing and Materials (ASTM) Practice E-1527-13, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process (ASTM Standard). Exceptions to, or deletions from, this practice are described in this report. The purpose of this assessment was to identify known, potential or historic recognized environmental conditions (RECs) resulting from historic and/or current uses of hazardous substances or petroleum products at the Site. We understand Bullock Ranch, LLC is considering purchasing the Site and is interested in qualifying for the liability protections granted under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The findings of this environmental assessment are based on Haro Environmental’s knowledge of the Site from observations and information gathered during this Phase I ESA. The Site is an approximately 5.6-acre property with most of the Site currently vacant, undeveloped land. Development at the Site is at the southwest corner and includes one residence, one garage, one storage shed, and one greenhouse. The Site has been designated San Luis Obispo County Assessor’s Parcel Number 004-705-009. Undeveloped land and rural residential land uses are present to the north, northeast, east, and southeast, and Bullock Lane followed by railroad tracks are present to the southwest. Results of a regulatory agency database search indicate the Site is not listed in any of the databases searched by EDR. Several nearby properties were listed in the databases searched, however, based on either the distance from the Site, the location of these properties relative to the Site (i.e., at a lower elevation), or on the type of listing (non-release facility with no violations), these listed nearby properties are not expected to pose an environmental concern to the Site. A review of historic aerial photographs, topographic maps and city directories listings indicate the Site vacant, undeveloped land from at least 1897 to at least 1939, and developed with the several of the present day structures by at least 1949. Multiple smaller structures may have been present at the Site, however, the quality of the aerial photographs are such the specific types and uses are unable to be determined. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page ii Haro Environmental, Inc. A reconnaissance of the Site was conducted by a Haro Environmental representative on November 8, 2017. During the reconnaissance, Haro Environmental observed small quantities (5-gallon bucket) of petroleum products (likely used motor oil) and two automotive batteries on bare soil at the Site adjacent to the north of the storage shed. Minor staining of the soil surface beneath the bucket was observed. At the property to the north, two leaking 55-gallon drums and one approximately 250-gallon above ground storage tank (AST) were observed near the property line. Based on the data gathered and reviewed during this Phase I ESA, Haro Environmental did not identify recognized environmental conditions or concerns that have impacted, or pose a significant environmental threat to subsurface soil, soil vapor, or groundwater beneath the Site. During preparation of this Phase I ESA, Haro Environmental identified the following conditions to note:  The presence of a 5-gallon drum with stained soil and two automotive batteries on bare soil adjacent to the north of the storage shed at the Site.  The presence of two leaking 55-gallon drums and an AST at the property to the north. The 5-gallon bucket and automotive batteries as well as the stained soil beneath the bucket should be removed from the Site and property disposed of in accordance with all applicable State and local rules and regulations. Although the 55-gallon drums at the property to the north were observed to be leaking, the contents appeared to be used motor oil, did not appear to be impacting the subject Site, and therefore are not expected to pose an environmental concern to the Site. In addition, the AST did not appear to be leaking and is not expected to pose an environmental concern to the Site. Because we have no evidence indicating that the Site has been significantly impacted by hazardous materials or petroleum products, no additional assessment appears warranted at this time. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 1 Haro Environmental, Inc. 1.0 INTRODUCTION ___________________________________________________________________________________ This Phase I Environmental Site Assessment (Phase I ESA) of the property located at 3580 Bullock Lane in the City of San Luis Obispo, California (the Site) was performed by Haro Environmental for Bullock Ranch, LLC. A site vicinity map is provided on Plate 1. Haro Environmental performed this Phase I ESA consistent with the American Society for Testing and Materials (ASTM) Practice E-1527-13, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process (ASTM Standard). Exceptions to, or deletions from, this practice are described in Section 7.0 this report. 1.1 PURPOSE This Phase I ESA was conducted in an effort to identify known, potential or historic recognized environmental conditions (RECs) resulting from historic and/or current uses of the Site. We understand this information will be used to qualify for the liability protections granted under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The ASTM Standard defines a REC as: “The presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment.” The term includes hazardous substances or petroleum products even under conditions in compliance with laws. The term is not intended to include de minimis conditions that generally do not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. Conditions determined to be de minimis are not recognized environmental conditions” The ASTM Standard defines a historical REC as: “An environmental condition which in the past would have been considered a recognized environmental condition, but which may or may not be considered a recognized environmental condition currently.” For example, a historical REC could be identified if a past release of any hazardous substances or petroleum products has occurred in connection with the property and has 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 2 Haro Environmental, Inc. been remediated to the satisfaction of the lead regulatory agency as evidenced by a no further action letter or a case closure determination. At the request of Bullock Ranch, LLC, whom we understand is considering purchasing the Site, Haro Environmental has completed this Phase I ESA. This report is subject to the limitations presented in this Phase I ESA report. This report describes Haro Environmental’s assessment methodology, presents our findings, and provides our opinion as to the potential presence of RECs in connection with the Site. 1.2 SCOPE OF SERVICES The scope of services conducted for this study included the following tasks:  Perform an on-site reconnaissance to identify indicators of the existence of hazardous materials or petroleum products.  Observe adjacent or nearby properties from the Site and public thoroughfares in an attempt to see if such properties are likely to use, store, generate, or dispose of hazardous materials or petroleum products.  Obtain and review an environmental records database search from Environmental Data Resources, Inc. (EDR) to acquire information about the potential for hazardous materials to exist at on-site or at nearby properties.  Review the current U.S. Geological Survey (USGS) topographic map to obtain information about topography and uses of the Site and nearby properties.  Review historic aerial photographs, topographic maps, and city directories listings to obtain information about historic uses of the Site and adjacent properties.  Review California Division of Oil and Gas records to obtain information about historic oil and gas activity in the vicinity of the Site. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 3 Haro Environmental, Inc.  Conduct interviews with persons familiar with the Site development and local and/or State government agencies to obtain information about current and historic uses of the property.  Prepare this report documenting the findings of the Phase I study. Our scope of services did not include any inquiries with respect to non-scope ASTM considerations including but not limited to asbestos containing materials, radon gas, lead-based paint, lead in drinking water, mold, wetlands, regulatory compliance, cultural and historic resources, industrial hygiene, health and safety, ecological resources, endangered species, indoor air quality, electromagnetic fields or geologic hazards. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 4 Haro Environmental, Inc. 2.0 SITE SETTING ___________________________________________________________________________________ The Site setting presented in this section describes the condition of the Site at the time of the Phase I ESA. Tables 2-1 and 2-2 summarize the physical characteristics of the Site and adjoining properties. A Site and Adjacent Land Use Map is provided on Plate 2. 2.1 SITE DESCRIPTION Table 2-1 provides a summary of the physical location and size of the Site, as well as the current uses. This information was obtained from review of various maps (such as topographic maps and tax assessor maps), aerial photographs, and a site visit. Additional site description information was obtained during the site visit; please refer to the Section 5.0 of the report that covers site reconnaissance information. TABLE 2-1 SITE LOCATION AND LAND USE Parameter Information/Comments Location The Site is located at the north side of Bullock Lane in an area of rural residential land uses. Assessor’s Parcel No. (APN) 004-705-009 Section, Township, and Range Section 1, Township 31 South, Range 12 East of the Mount Diablo Base and Meridian. Current Use The Site is currently in residential land use and is developed with one residence, a garage, a storage shed, and a greenhouse. 2.2 REGIONAL GEOLOGY AND HYDROGEOLOGY Information on regional geology and hydrogeology is presented in Table 2-2. This information was obtained from published data and maps of the Site vicinity. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 5 Haro Environmental, Inc. TABLE 2-2 PHYSICAL AND ENVIRONMENTAL CHARACTERISTICS Geologic/Hydrogeologic Parameter Information/Comments Site Topography Based on a review of the USGS San Luis Obispo, California 7.5 minute Topographic Quadrangle Map dated 2012, elevation at the Site ranges from approximately 215 feet above Mean Sea Level (MSL) at the southwest corner to approximately 240 feet above MSL at the northwest corner, with relief across the Site generally sloping to the southwest. Surface/stormwater water runoff flows towards Bullock Lane. Site Geology and Soil Types The Site is located within the Coast Ranges of the California Geomorphic Provinces (CGS, 2002). The Coast Ranges are characterized by a series of northwest trending ranges and valleys, sub-parallel to faults branching from the San Andres Fault. These ranges extend into southern California and are bound on the east by the Great Valley, on the south by the Transverse Ranges, to the west by the Pacific Ocean, and to the north by the Klamath Mountains. According to the Geologic Map of the San Luis Obispo 7.5-Minute Quadrangle (CGS, 2010), the Site is underlain by Holocene- to late- Pleistocene-aged alluvial flood plain deposits. Beneath the alluvium is bedrock of the Jurassic-Cretaceous age Franciscan Formation. The Franciscan Formation is dominated by serpentinite, metavolcanic rocks, chert, and greywacke sandstone (DWR, 1975). According to the Geocheck® section of the EDR report (Appendix A), soils at the Site are dominated by the Cropley soils. Cropley soils have a clay surface texture with a high shrink-swell potential, and are classified by very slow infiltration rates and are moderately well drained. Site Hydrogeologic Setting The Site is not located within a groundwater basin as defined in California’s Groundwater Bulletin 118 (DWR, 2017). According to the GeoCheck® section of the EDR report (Appendix A), there are not groundwater wells located within a one-quarter mile radius of the Site. In addition, no groundwater wells were observed at or adjacent to the Site during the site reconnaissance. 2.3 ADJOINING AREA LAND USE A drive-by survey of the area adjoining to the Site was performed by Haro Environmental personnel on November 8, 2017. The results of this survey indicate rural residential land uses are present to the north and south, undeveloped land to the northeast, and Bullock Lane followed by railroad tracks to the southwest. Site and adjoining land uses are depicted on Plate 2. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 6 Haro Environmental, Inc. 2.4 LOCATION AND LEGAL DESCRIPTIONS The Site is located on the north side of Bullock Lane, southeast of Orcutt Road, and is identified by the County of San Luis Obispo Assessors office as APN 004-705-009. 2.5 USER PROVIDED INFORMATION Mr. Barry Ephraim, Partner with Bullock Ranch, LLC, was interviewed for actual knowledge pertaining to the Site to help identify the possibility of RECs in connection with the Site. A copy of a user questionnaire completed by Mr. Ephraim is provided in Appendix B. The results of the interview are provided below. 2.5.1 Title Records Haro Environmental was provided and reviewed the Preliminary Title Report dated October 5, 2017 prepared by First American Title Company. No information regarding deed restrictions or environmental liens were noted during our review of the October 5, 2017 Preliminary Title Report. A copy of the Title Report is provided in Appendix B. 2.5.2 Environmental Liens or Activity and Use Limitations Mr. Ephraim is unaware of any information pertaining to environmental liens or activity and use limitations for the Site. Haro Environmental was not provided with a copy of an environmental lien records search for the Site. 2.5.3 Specialized Knowledge Mr. Ephraim did not provide Haro Environmental with any information pertaining to specialized knowledge or experience regarding the Site. 2.5.4 Commonly Known or Reasonably Ascertainable Information Mr. Ephraim did not provide Haro Environmental with and was not aware of any information pertaining to commonly known or reasonably ascertainable information about the Site. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 7 Haro Environmental, Inc. 2.5.5 Valuation Reduction for Environmental Issues Mr. Ephraim was not aware of and did not provide Haro Environmental with any information pertaining to a valuation reduction for the Site relative to any known environmental issues. 2.5.6 Owner, Property Manager, and Occupant Information Mr. Ephraim indicated that based on his knowledge and experience related to the property, there are no obvious indicators that point to the presence or likely presence of contamination at the Site. 2.5.7 Reason for Performing Phase I ESA The purpose of this Phase I ESA was to assess the environmental conditions of the Site, taking into account commonly and reasonably ascertainable information. 2.5.8 Other No other information pertinent to the condition of the Site was provided to Haro Environmental by Mr. Ephraim. 2.6 ENVIRONMENTAL LIENS No environmental lien search was conducted by the preparer or the user of this Phase I report. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 8 Haro Environmental, Inc. 3.0 RECORDS REVIEW ___________________________________________________________________________________ Government agency database records are sources of information that may be helpful in evaluating activities that may have contributed to a release of hazardous substances or petroleum products to soil and/or groundwater. Haro Environmental contracted a government agency database search from EDR. A copy of the EDR report, which specifies the approximate minimum search distance for each public list as defined in the ASTM Standard, is included as Appendix A. The subject Site was not listed in any of the databases searched by EDR. Results of the regulatory agency database search performed by EDR indicate multiple properties are listed within the approximate minimum search distance, however, based on either distance from the Site, the topographic position relative to the Site (i.e., at a lower elevation), or on the nature of the listing (non- release site or site with no violations), these nearby listed properties would not be expected to pose an environmental concern to the Site (see Appendix A for a complete listing of properties reported and acronyms used by EDR). 3.1 RESULTS OF DATABASE SEARCH The following sections contain information on the results of the government records search conducted by EDR. Opinions presented below are based on information provided in EDR’s report (unless otherwise noted) and on criteria such as distance from the Site, anticipated groundwater movement direction in the vicinity of the Site, and the nature of any reported unauthorized releases. In assessing the potential impact to buildings materials, soil, soil vapor, and/or groundwater beneath the Site, the shallowest groundwater was considered with an anticipated groundwater movement direction assumed to follow the local topographic gradient to the southwest. 3.1.1 Subject Property The Site was not listed in any of the databases searched by EDR. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 9 Haro Environmental, Inc. 3.1.2 Adjacent and/or Nearby Properties Numerous properties near the Site were listed in the databases searched by EDR, however, based on either distance from the Site or on the nature of the listing (non-release site), none of these nearby listed properties would be expected to pose an environmental concern to the Site (see Appendix A for a complete listing of properties reported and acronyms used by EDR). 3.1.3 Orphan List Sites not plotted by EDR due to poor or inadequate address information are referred to as orphan sites. There were three unmapped orphan sites listed in the EDR Report. The orphan summary/unmapped sites report was reviewed by Haro Environmental to assess the potential for off-site properties to affect the subject Site. Because they have incomplete addresses, these orphan sites are not practically reviewable as defined by the ASTM standard. However, based upon the street names, locations reported, and Haro Environmental’s knowledge of the area, the orphan/unmapped sites identified by EDR would not be expected to pose a significant environmental concern to subsurface soils, soil vapor, or groundwater at the Site. 3.1.4 Non-ASTM Issues Assessment of non-ASTM issues including but not limited to asbestos containing materials, lead-based paint, lead in drinking water, mold, regulatory compliance, cultural and historic resources, industrial hygiene, health and safety, ecological resources, endangered species, indoor air quality, electromagnetic fields or geologic hazards were not included as part of this Phase I ESA. 3.2 OTHER RECORDS REVIEWED The following additional sources of information were reviewed as part of this Phase I ESA. 3.2.1 Public Agency Records Building permit information was reviewed at the City of San Luis Obispo Planning and Building Department and contained two permits for electrical upgrades. Building permit information was also requested from the County of San Luis Obispo Planning and Building Department and as of the writing of this report the County has not responded to our request for information. If the County provides 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 10 Haro Environmental, Inc. information after the Phase I ESA report is published that changes the findings of this Phase I ESA, an addendum letter will be forwarded to Bullock Ranch, LLC detailing the findings and providing an opinion regarding the potential to impact soil, soil vapor, and/or groundwater beneath the Site. The following additional public agencies were contacted regarding files for the Site and indicated they do not maintain files for the Site.  County of San Luis Obispo Environmental Health Services (CSLOEHS)  California Department of Toxic Substances Control (Envirostor Website)  County of San Luis Obispo Air Pollution Control District  County of San Luis Obispo Department of Planning and Building  Central Coast Regional Water Quality Control Board  State Water Resources Control Board (Geotracker website) 3.2.2 Previous Environmental Reports No previous environmental reports were provided to Haro Environmental for review. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 11 Haro Environmental, Inc. 4.0 SITE HISTORY ___________________________________________________________________________________ The history of the site was researched to identify obvious uses of the site back to the first developed use, or at least 40 years ago, whichever is earlier or readily available. Several data gaps since 1940 of greater than 5 years were identified in the historical records reviewed and included the years from 1942 to 1948 and from 1979 to 1987. These data gaps are considered insignificant because the site use appears to be similar during the data gaps or the site use is well documented via other historical research documents. 4.1 AERIAL PHOTOGRAPHS A review of historical aerial photography may indicate past activities at a property that may not be documented by other means, or observed during a site visit. The effectiveness of this technique depends on the scale and quality of the photographs and the available coverage. Aerial photographs were obtained from several historical photograph collections through EDR. A tabulation of the aerial photographs reviewed is presented in Table 4-1.

No Sanborn Fire Insurance Map coverage was available for the Site and a copy of the no coverage letter is included in Appendix A. 4.4 CITY DIRECTORIES Haro Environmental contacted EDR to obtain a historical City Directory Abstract, which lists the names and/or businesses that historically occupied an address. The City Directory Abstract, which covers the period from 1967 to 2014, provides tenant information for an address and/or adjoining streets. The City Directories reviewed did not provide information which would pose an environmental concern to the Site. The complete EDR City Directory Abstract listing results is provided in Appendix A. 4.5 OIL AND GAS MAPS Maps provided online by the California Department of Conservation, Division of Oil, Gas, and Geothermal Resources were reviewed to determine the current or historic presence of oil or gas wells in the vicinity of 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 15 Haro Environmental, Inc. the Site (DOGGR, 2014). The maps reviewed indicate there are no oil or gas wells located within a one- mile radius of the Site. 4.6 CRUDE OIL PIPELINES The National Pipeline Mapping System maintained by the Pipeline and Hazardous Materials Safety Administration was reviewed for the presence of gas and hazardous liquid transmission pipelines, and the results indicate there is one gas transmission pipeline located approximately 700 feet southwest of the Site. (PHMSA, 2017). This pipeline is reportedly owned by Southern California Gas Company and carries natural gas. Based on the contents of this pipeline and distance from the Site, impacts to soil, soil vapor, and/or groundwater beneath the Site are not expected. 4.7 CHAIN OF TITLE RECORDS Haro Environmental was provided and reviewed the Preliminary Title Report dated October 5, 2017 prepared by First American Title Company.

This section summarizes the findings from the site reconnaissance. 5.1 SITE RECONNAISSANCE 5.1.1 Methodology and Limiting Conditions Mr. Elliot Haro of Haro Environmental performed an unaccompanied reconnaissance of the Site on November 8, 2017. The site reconnaissance was conducted by: 1) observing the Site from public thoroughfares, 2) observing the adjoining properties from public thoroughfares, 3) observing the interior of the onsite structures, 4) observing the exterior of the onsite structures, 5) backtracking to correlate exterior features with interior features, as necessary, and 6) observing the Site from walking paths. The purpose of the site reconnaissance was to identify the presence or likely presence of hazardous substances or petroleum products under conditions that indicate an existing release, a past release, or threat of release into soil, groundwater, or surface water at the Site (recognized environmental conditions). Observations from the site reconnaissance are summarized in the following sections. A photolog of photographs taken during the site reconnaissance is included as Appendix C. 5.1.2 Current Use of the Property and Adjoining Properties The majority of the Site is vacant, undeveloped land with the southwestern portion in residential land use. Properties to the north and south are in residential land use and also used for storage of equipment and supplies. The property to the west is Bullock Lane followed by railroad tracks, and the property to the east is vacant, undeveloped land. Nearby land uses are depicted on Plate 2. 5.1.3 General Description of Structures There are four structures present at the Site and include one residence (Photos #1 and #2), a garage (Photo #4), a greenhouse (Photo #5), and a storage shed (Photo #3). The residence is approximately 1,200- 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 17 Haro Environmental, Inc. square feet, wood-frame construction with stucco siding constructed on a raised foundation. The garage and storage shed are wood-frame construction and wood siding, and the greenhouse is wood-frame with plastic siding. 5.1.4 Interior and Exterior Observations The interior of the residence and garage were not observed. The interior of the storage shed contains small quantities of paints and cleaners, and the greenhouse has plant containers. 5.1.5 Hazardous Substances and Petroleum Products Hazardous substances or petroleum products were observed during the site reconnaissance behind the shed and on the property adjacent to the north. To the north of the storage shed at the Site, one 5-gallon bucket with used motor oil was observed with stained soil (Photo #16), and two automotive batteries were observed (Photo #17). At the property to the north, two leaking 55-gallon drums with stained soil were observed (Photo #13) and one approximately 250-gallon above ground storage tank (AST; Photo #14). 5.1.6 Unidentified Substance Containers Unidentified hazardous substance containers or unidentified containers that might contain hazardous substances were observed during the site reconnaissance. These containers are discussed in Section 5.1.5. 5.1.7 Storage Tanks During the site reconnaissance, Haro Environmental did not observe evidence of above-ground storage tanks (ASTs) or underground storage tanks (USTs) at the Site. One AST was observed at the proepty adjacent to the north and is discussed in Section 5.1.5. 5.1.8 Odors During the site reconnaissance, Haro Environmental did not identify any strong, pungent, or noxious odors. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 18 Haro Environmental, Inc. 5.1.9 Pools of Liquid During the site reconnaissance, Haro Environmental did not identify any pools of liquid including standing surface water. In addition, sumps containing liquids likely to be hazardous substances or petroleum products were not observed. 5.1.10 Drums During the site reconnaissance, Haro Environmental did not observe evidence of drums onsite. Several drums were observed at the property to the north and the details regarding these drums are discussed in Section 5.1.5. 5.1.11 Indications of Polychlorinated Biphenyls (PCBs) During the site reconnaissance, Haro Environmental did not observe evidence of PCBs onsite. 5.1.12 Other Conditions of Concern During the site reconnaissance Haro Environmental did not note or observe evidence of any of the following:  Corrosion  Clarifiers, and/or sumps  Pits, ponds, and/or lagoons  Stressed vegetation  Waste water  Septic tanks  Fill soil Solid waste was observed at several locations at the Site including within the storage shed (Photo #15), behind the residence, and southeast of the residence (Photo #18). 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 19 Haro Environmental, Inc. 5.2 INTERVIEWS No interviews with the current property owner or key site manager were performed as part of this Phase I ESA. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 20 Haro Environmental, Inc. 6.0 FINDINGS, CONCLUSTIONS AND RECOMMENDATIONS This Phase I ESA of the property located at 3580 Bullock Lane in the City of San Luis Obispo, California was performed by Haro Environmental for Bullock Ranch, LLC. Haro Environmental performed this Phase I ESA consistent with ASTM Practice E-1527-13, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process (ASTM Standard). Exceptions to, or deletions from, this practice are described in this report. Based on the data gathered and reviewed during this Phase I ESA, Haro Environmental did not identify recognized environmental conditions or concerns that have impacted, or pose a significant environmental threat to subsurface soil, soil vapor, or groundwater beneath the Site. During preparation of this Phase I ESA, Haro Environmental identified the following conditions to note:  The presence of a 5-gallon drum with stained soil and two automotive batteries on bare soil adjacent to the north of the storage shed at the Site.  The presence of two leaking 55-gallon drums and an AST at the property to the north. The 5-gallon bucket and automotive batteries as well as the stained soil beneath the bucket should be removed from the Site and property disposed of in accordance with all applicable State and local rules and regulations. Although the 55-gallon drums at the property to the north were observed to be leaking, the contents appeared to be used motor oil, did not appear to be impacting the subject Site, and therefore are not expected to pose an environmental concern to the Site. In addition, the AST did not appear to be leaking and is not expected to pose an environmental concern to the Site. Because we have no evidence indicating that the Site has been significantly impacted by hazardous materials or petroleum products, no additional assessment appears warranted at this time. 2017-1227_3580 Bullock Phase I ESA-DRAFT Page 21 Haro Environmental, Inc. 7.0 STANDARD OF CARE ___________________________________________________________________________________ The findings and conclusions contained in this Phase I ESA are based upon professional opinions with regard to the subject matter.
