• 7.0 GOVERNMENT AGENCY RESEARCH <br /> 7.1 EPA-Databases <br /> The California Environmental Protection Agency (EPA) manages contaminated <br /> sites through two sub-agencies: the State Water Resources Control Board <br /> (SWRCB) and the Department of Toxic Substances Control (DTSC). The <br /> SWRCB's GeoTracker database includes underground storage tank (UST) sites, <br /> leaking underground storage tank (LUST) sites, cleanup program sites, and land <br /> disposal sites. The database can be searched by reviewing two lists, the <br /> Permitted Underground Storage Tank (UST) Sites list and the Cleanup Sites list. <br /> DTSC's EnviroStor database includes Federal Superfund sites, State response <br /> sites, voluntary cleanup sites, school cleanup sites, corrective action sites, and <br /> permitted hazardous waste facilities. <br /> Live Oak searched both databases on October 20, 2015 for any listed sites within <br /> one-quarter mile of the Site. The subject Site was not listed on either database, <br /> and no other facilities were identified within one-quarter mile. <br /> 7.2 Environmental Health Department Databases <br /> Live Oak reviewed the San Joaquin County Environmental Health Department's <br /> • Hazardous Materials, Hazardous Waste Generators, Underground Storage <br /> Tanks, Aboveground Storage Tanks, Site Mitigation, and Leaking Underground <br /> Storage Tanks lists dated August 2015, for facilities of concern within one-quarter <br /> mile of the Site. No facilities were identified within the search radius. <br /> Live Oak searched the San Joaquin County Haz Mat Viewer on October 27, <br /> 2015 for the Site and nearby facilities with hazardous materials inventories. The <br /> Site was not listed, and no facilities within one-quarter mile were identified. <br /> Live Oak reviewed the San Joaquin County Environmental Health Department's <br /> Water Well Data Table dated March 10, 2009 for nearby addresses that have <br /> been tested for nitrate and dibromochloropropane (DBCP). Six wells were <br /> identified at addresses within approximately 1.5 miles of the subject Site. Five of <br /> the wells had been tested for DBCP; it was only detected in one well, at a <br /> concentration of 0.2 µg/L. All of the wells had been tested for nitrate; it was <br /> detected in all the wells at concentrations from 6.8 to 38 mg/L. The Maximum <br /> Contaminant Level (MCL) set by the US EPA for nitrate as NO3 is 45 mg/L. The <br /> MCL for DBCP is 0.2 µg/L. <br /> • <br /> LOGE 1524 4 <br />
