2008-2009— Metal recycler—petroleum products(lubricants, solvents) 2. Indications of Past Spills/Releases No specific records of spills or releases have been reported at 248 Industrial Drive. Prior records review and requests discovered two limited Phase 11 investigations had been completed at the subject property. These prior reports are summarized below: 1997 Limited Soil Sampling - That report was referenced (but not attached) in a 2008 Transaction Screen Assessment(TSA) issued by Lush Geosciences Inc. (LGI). According to LGI the 1997 report found total recoverable petroleum hydrocarbon(TRPH) impact of up to 1,900 parts per million (ppm) at 5 feet below ground surface (bgs) in boring B-1 near the asphalt-containing ASTs, 160 ppm TRPH at 10 feet bgs in boring B-2, and no TRPH impact in boring B-3 near the AST that stored diesel fuel. LSI indicated that no volatile constituents were found, but did not describe what analyses were performed. September 27, 2010 —Limited Phase II Subsurface Investigation Report completed by PTS, Inc., for Mr. Tony Nam (Alco Iron & Metal) and the U.S. Small Business Administration (SBA). The scope of work consisted of five soil borings to five feet bgs. Heavy petroleum hydrocarbons were found up to 1,100 mg/kg. No VOCs were detected. During PEI's Limited Phase II Subsurface Investigation (April 2012) and Addendum Subsurface Sampling(September 2012),PEI discovered impact to groundwater with low levels of volatile organic constituents (VOCs) in the area of the septic system on the eastern border of the subject property. In addition, two concrete patches in the building interior were noted to cover heavy-hydrocarbon impacted soil. 3. UST and AST Locations No specific evidence of past or present underground storage tanks (USTs) was noted. Leatherback Industries (an asphalt roofing plant) reportedly used three large (20,000-gallon) above ground storage tanks (ASTs) and a large (20,000-gallon) diesel fuel AST on the east side of the main building. Concrete pads associated with these ASTs are visible. Based upon 1994 site diagrams in agency files, and contemporaneous with the presence of ASTs, a large portion of the site was previously unpaved;therefore,the former ground surfaces (and possible past releases) are no longer visible in these areas. The on-site geophysical survey was completed by Sierra Nevada GSI (Sierra) in March 2012. Sierra found several radar anomalies, including four potential USTs, underground utilities, and two large septic tanks. Subsequent subsurface investigation of the geophysical anomalies indicated the former presence of two USTs near the southeast corner of the building (PEI, Limited Phase 11, April 25, 2012). 4. Maintenance Shop, Chemical Storage Areas The site is vacant. A former chemical storage area was located within the central portion of the northeastern side of the subject building. This area was investigated with a soil
