7.0 GOVERNMENT AGENCY RESEARCH <br /> 7.1 EPA Databases <br /> The California Environmental Protection Agency (EPA) manages contaminated sites <br /> through two sub-agencies: the State Water Resources Control Board (SWRCB) and the <br /> Department of Toxic Substances Control (DTSC). The SWRCB's GeoTracker database <br /> includes underground storage tank (UST) sites, leaking underground storage tank <br /> (LUST) sites, cleanup program sites, and land disposal sites. DTSC's EnviroStor <br /> database includes Federal Superfund sites, State response sites, voluntary cleanup <br /> sites, school cleanup sites, corrective action sites, and permitted hazardous waste <br /> facilities. <br /> Live Oak searched both databases on March 10, 2011. for any listed sites within one- <br /> quarter mile of the Site. The subject Site was not listed on either database. <br /> One facility was identified within one-quarter mile of the Site. Sebastiani Vineyards, C3, <br /> located at 4614 West Turner Road, adjacent to the south of the subject Site, was listed <br /> on GeoTracker as a leaking underground storage tank case. The case was closed in <br /> 2000. It is discussed in Section 7.2 below. <br /> 7.2 Environmental Health Department Databases <br /> Contaminated Site Databases <br /> On .lune 4, 2010, Live Oak reviewed two databases maintained by the EHD, the /� 3 <br /> Underground Storage Tank Site Mitigation List, dated May 5, 2010, and the Unit 1V l <br /> Sites (LOP) list, dated May 2010, for surrounding facilities of concern. No additional /�J <br /> listings were identified. <br /> Live Oak reviewed the records on file at the EHD for the Sebastiani Vineyards facility <br /> discussed above. According to a summary of action at this facility found in the EHD file, <br /> a 550-gallon underground gasoline tank was removed in 1988. Odor and discoloration <br /> were observed, and laboratory results confirmed contamination. Groundwater <br /> monitoring wells were installed starting in 1989, and a groundwater treatment system <br /> was initiated in 1992. By 1998, groundwater sampling found that the previously <br /> identified contaminants were no longer detectable. The wells were destroyed in 2000, <br /> and the case was closed by the Central Valley Regional Water Quality Control Board f`✓`/' <br /> with concurrence by the EHD. According to the Problem Assessment Report and Site <br /> Closure Document prepared by WZI Inc. (1997), the predominant groundwater flow <br /> direction from Sebastiani Vineyards is to the southeast, away from the Site. <br /> A 2010 Quarterly Monitoring Report prepared by Wallace-Kuhl indicates that the <br /> Sebastiani facility (now Canandaigua Wine) is being required to conduct quarterly <br /> LOGE 1111 Page 5 <br />
