• PG&E Vernalis, Durham Ferry Road eight miles southeast of Tracy. According to GeoTracker, a leak was reported in 1965, and the drinking water aquifer was impacted with petroleum, fuels, oils, and benzene. The case was closed in 2002. The exact location of this facility is not apparent. However, based on review of historical aerial photographs, there is no evidence of structures along Durham Ferry Road within one-quarter mile of the project Site. 7.2 Environmental Health Department Databases Live Oak reviewed two databases maintained by the EHD, the Underground Storage Tank Site Mitigation List, dated May 7, 2010, and the Unit IV Sites (LOP) list, dated May 2010, for surrounding facilities of concern. One listed facility was found within one- quarter mile of the subject Site. • Alegre Trucking, 28902 Kasson Road. Although the access road for this property is within the quarter-mile radius of the Site, the majority of the property is located over one mile northeast. An environmental assessment was conducted on the property; the case is closed. Live Oak reviewed the EHD's Water Well Data Table dated March 10, 2009 for nearby addresses that have been tested for nitrate and dibromochloropropane (DBCP). Three nearby wells were identified at addresses located within approximately 1.5 miles of the Site. None of the wells had been tested for DBCP. Nitrate as NO3 was detected in all three wells at concentrations of 8.0 to 25.5 parts per million (ppm). The Maximum Contaminant Level (MCL) set by the US EPA for nitrate as NO3 is 45 ppm. 7.3 Office of Emergency Services Databases The San Joaquin County Office of Emergency Services (OES) Hazardous Materials Management Program (HMMP) Compliance Website was searched on March 25, 2011. An Agricultural Hazardous Materials Inventory was identified for the Site address under the name of J. Lombardi Farms; the inventory was not accessible due to security restrictions. Michelle Halliwell of the OES was interviewed by telephone on March 25, 2011.
