Live Oak searched both databases on June 13, 2010 for any listed sites within one- <br /> quarter mile of the Site. The subject Site was not listed on either database. The <br /> following facilities were identified within one-quarter mile of the Site: <br /> • Edward Sprague, 23160 Davis Rd.: This facility is listed by GeoTracker as a <br /> permitted UST location. Its exact location could not be identified, but it is likely <br /> located at least one-eighth of a mile west of the Site. <br /> • Lodi Concrete Pipe Service, 381 W. Taddei Rd.: This facility is listed by <br /> GeoTracker as a closed LUST case. The leak reportedly involved gasoline and <br /> affected soil only; the case was closed in 1994. 3t is located approximately one- <br /> quarter mile south of the Site. <br /> 7.2 Environmental Health Department Databases <br /> On June 4, 2010, Live Oak reviewed two databases maintained by the EHD, the <br /> Underground Storage Tank Site Mitigation List, dated May 5, 2010, and the Unit IV <br /> Sites (LOP) list, dated May 2010, for surrounding facilities of concern. No additional <br /> listings were identified. <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), <br /> common ground water contaminants in San Joaquin County. Four nearby wells were <br /> identified at addresses located within approximately one-quarter mile of the Site. Three <br /> of the wells had been tested for DBCP; it was detected in only one, at a concentration of <br /> 0.8 parts per billion (ppb). Detected concentrations of nitrate as NO3 within these wells <br /> ranged from 4 to 13.7 parts per million (ppm). The Maximum Contaminant Level (MCL) <br /> set by the US EPA for DBCP is 0.2 ppb; the MCL for nitrate as NO3 is 45 ppm. <br /> ,-""7.3 Office of Emergency Services Databases <br /> The San Joaquin County Office of Emergency Services (OES) Hazardous Materials <br /> Management Program (HMMP) Compliance Website was searched on June 10, 2010. <br /> No records were identified for the Site addresses. <br /> Michelle Halliwell of the OES was interviewed by telephone on June 23, 2010. She <br /> indicated at this time that no hazardous materials incident reports are on file in the OES <br /> database for the Site addresses or nearby locations on Bender or Jahant Roads. <br /> LOGE1014 <br /> Page 5 <br />
