Main St., Cleanup Sites list (case closed). These facilities are discussed below. 7.2 Environmental Health Department Databases Live Oak reviewed the San Joaquin County Environmental Health Department's Cleanup, Site Mitigation, Hazardous Materials, Hazardous Waste Generators, Underground Storage Tanks, Aboveground Storage Tanks, and Complaints databases, dated December 2022, for facilities of concern within one-quarter mile of the Site. The subject Site was not included on any of the databases. A total of 19 listed sites were identified within the search radius: • Jamar Service, 4075 E. Main St., approximately 230 feet south-southwest of the Site, Cleanup, Site Mitigation, Hazardous Materials, Hazardous Waste Generators, Underground Storage Tanks, and Complaints lists. Live Oak reviewed records on file at the San Joaquin County Environmental Health Department and GeoTracker for this facility. According to the files, a 350-gallon waste oil UST and a 500-gallon kerosene UST were removed from this facility in 1995, and two 6,000- gallon gasoline USTs and a 10,000-gallon gasoline UST were removed in 1998. A soil and ground water investigation was conducted from 1999 through 2020, including monitoring wells, soil vapor extraction wells, a ground-water extraction well, injection wells, and soil gas probes. Impacted soil was determined to extend north for 75 feet, and an impacted ground-water plume was identified extending east from this facility past Adelbert Avenue. According to a 2021 Public Notice by the California Environmental Protection Agency, "the results of the investigation have concluded that the remaining hydrocarbon impact to soil and groundwater does not appear to pose any significant threat to human health, the environment, or future site activities." The case has been recommended for closure by the Central Valley Regional Water Quality Control Board. Three monitoring wells remain in place adjacent to the subject Site, MW13A, B, and C. According to the Monitoring Well Destruction Workplan (ATC, 2021), no constituents of concern have been detected at these wells, which are screened at various depths from 60 to 110 feet. The Central Valley Regional Water Quality Control Board ordered in a November 2022 letter that these and other monitoring wells be destroyed by February 2023. In 1999, three new gasoline USTs were installed: a 10,000-gallon tank and two 6,000-gallon tanks. A 2022 Hazardous Materials Program Inspection Report identified several paperwork violations; Corrective Action Statements were on file. A 2021 Small Quantity Hazardous Waste Generator Inspection Report did not identify LOGE 2251 6
