r l PUBLIC NOTICE Fact Sheet Pending Case Closure for Leaking Underground Storage Tank Site Advanced Geo Environmental, Inc. (AGE), on behalf of the San Joaquin County Environmental Health Department (SJCEHD), invites public comment regarding the SJCEHD consideration to grant regulatory closure for a leaking underground storage tank (LUST)case on the Site identified below. SUBJECT SITE: Site Name: Harry's Auto Mart GeoTracker Global ID#T0607700314 Site Address: 2662 North Wilson Way, Stockton, California SJCEHD Site Code: 1306 PUBLIC COMMENT PERIOD: 21 March—21 May 2014 CASE SUMMARY: The SJCEHD in cooperation with the property owner and the responsible party, Mr. John and Ms. Maxine Ferraiolo, and environmental consultant, AGE, have evaluated soil and groundwater conditions at the Site resulting from historical unauthorized releases of gasoline from an underground storage tank (UST) system and from fueling operations. The UST system, consisting of four USTs and associated piping, was removed from the Site in April 1989. Soil and groundwater investigations were conducted from 2000 to 2013. Gasoline hydrocarbons were detected in on-site soil and groundwater. Active remediation of soil and groundwater by soil vapor extraction (SVE) and in-situ air sparging (IAS) was conducted during a pilot test in 2011 and continued until early 2014. An estimated 42,500 pounds of petroleum hydrocarbons were removed from the subsurface through IAS and SVE. A soil vapor investigation was not conducted to evaluate the potential for indoor vapor intrusion into current and future Site buildings, as the State Water Resources Control Board (SWRCB) Cleanup Fund determined that the case meets the Low-Threat Closure Policy for vapor intrusion. The SWRCB has concluded that the Site status is protective of the environment and of human health for current and future Site use and for adjacent off-site areas. After receipt of notification that all case closure activities have been completed, the SJCEHD intends to issue a No Further Action Required letter for the subject Site.
