February 8, 2021 Project No. 21-6289 Page 14 Advanced An Employee-AwnedC0.rT3P 3y geographic perspective. AGI reviewed the CaIGEM Well Finder database for information that may be available for the subject property or surrounding sites. 3.4.1. Additional Subject Property Record Sources The subject property address was searched on the following record sources: SOURCE SUMMARY Regional Board & Property address was not listed on the GeoTracker database and did not have any GeoTracker database records on -file with the Regional Board. DTSC & ENVIROSTOR Property [address was not] listed on the ENVIROSTOR database and did not have database any records on -file with the DTSC. USEPA ENVIROFACTS Property address was not listed on the ENVIROFACTs database. SJVAPCD Property address was not identified as having records on -file with the SJVAPCD. SJCEHD Property address was identified as having records on -file with the SJCEHD. Records indicate that a septic tank was installed on the property in 1965. The septic tank was installed in the portion of the subject property excluded from this report. CalGem According to The Geologic Energy Management Division (CaIGEM) System, no oil and/or gas wells are located in the vicinity of the subject property. 3.4.2. Additional Site Vicinity Record Sources The SJCEHD and Regional Board maintain records for, and are responsible for, enforcement of state UST and hazardous waste laws. AGI commonly reviews files for up -gradient sites under active environmental regulation to ascertain the current site status and its potential to impact the subject property. No sites, under active or past environmental regulation, were identified by the database search within the required search radius of potential concern to the property. 3.5. PROVIDED SUBJECT PROPERTY RECORDS No records were provided to AGI by the user and/or property owner during the course of this Phase I. 3.6. VOLATILE ORGANIC COMPOUND VAPOR ENCROACHMENT The encroachment of hydrocarbon and volatile organic compound (VOC) vapors into soil pore space occurs when organic chemicals migrate from contaminated groundwater or soil into the airspace between soil particles. Some typical organics involved are petroleum based or chlorinated solvents (e.g, BTEX and dry cleaning chemicals). They may have leaked into the groundwater and/or soil from underground storage tanks, or buried waste, or from disposal in septic systems. In compliance with ASTM Standard E2600-15 (Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions), AGI evaluated the potential for a Vapor Encroachment Condition (VEC) at the subject property. Based on a VEC screening, it was determined that `a VEC does not exist' at the property. A copy of the AGI -generated Tier 1 VEC screening form is provided within Appendix E.
