• January 2001 permit for geotechnical borings. The location indicated appears to <br /> refer to the communications tower located north of Lone Tree Road, not part of <br /> the Site. <br /> • May 2004 permit for new irrigation well. The location is unclear but does not <br /> appear to be part of the Site. <br /> Copies of these records have been included in Appendix 4 of this report. <br /> 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. The database can be <br /> searched by reviewing two lists, the Permitted Underground Storage Tank (USTI Sites <br /> list and the Cleanup Sites list. DTSC's EnviroStor database includes Federal Superfund <br /> sites, State response sites, voluntary cleanup sites, school cleanup sites, corrective <br /> action sites, and permitted hazardous waste facilities. <br /> Live Oak searched both databases on November 30, 2012 for any listed sites within <br /> `r one-quarter mile of the Site. The subject Site was not listed on either database, and no <br /> listed facilities were identified within one-quarter mile of the Site. <br /> 7.2 Environmental Health Department Databases <br /> Live Oak reviewed the EHD's Underground Storage Tank Site Mitigation List, dated July <br /> 21, 2011, for surrounding facilities of concern. No listed facilities were identified within <br /> one-quarter mile of the Site. <br /> Live Oak reviewed the EHD's Water Well Data Table dated March 10, 2009 for nearby <br /> addresses that have been tested for nitrate and dibromochloropropane (DBCP). Five <br /> nearby wells were identified at addresses located within approximately 1.25 miles of the <br /> Site. Four of the wells had been tested for DBCP; it was detected in only one of the four <br /> at a concentration of 0.27 pg/L. The Maximum Contaminant Level (MCL) set by the US <br /> EPA for DBCP is 0.2 µg/L. Nitrate as NO3 was detected in all five wells at <br /> concentrations of 11.0 to 51.4 parts per million (ppm). The MCL for nitrate as NO3 is 45 <br /> ppm. <br /> -- LOGE 1225 Page 5 <br />
