Levand-Bright Property - 2 - 29 July 2016 3 East 11 th Street Tracy, San Joaquin County Family Trust. At the time the release was discovered and to the present date, both the Levand Family Trust and the Mildred Levand Bright Family Trust both own 50% of the property at 3 East 11th Street, Tracy. Copies of the San Joaquin County Recorder's Office individual grant deeds, and a parcel map are attached. As the owner of the property at the time the leak was discovered, and as a current property owner, the Mildred Levand Bright Family Trust is an additional Responsible Party. Under the Water Code, as owners and operators of an underground storage tank system at the time a leak is discovered, both Responsible Parties are obligated to clean-up the property at 3 East 11 th Street in Tracy. In the Work Plan, AGE proposes to: • Advance a total of eight (8) soil borings using direct push drilling technology to investigate the lateral and vertical extent of pollution. The soil boring located at the former UST was proposed to be advanced to a total depth of 40 ft bgs and up to 50 feet below ground surface (ft bgs) if contamination is observed, based on field observations of hydrocarbon odor and organic vapor meter concentrations at 40 ft bgs. The other seven (7) soil borings are proposed to be advanced to total depths of 20 ft bgs to assess the lateral extent of pollution. • Collect soil samples, and shallow and deep groundwater samples during advancement of the borings for submission to an analytical laboratory chemical analysis. • Submit soil and groundwater samples to a certified analytical laboratory for analysis of: total petroleum hydrocarbons as gasoline (TPH-G); benzene, toluene, ethylbenzene and total xylenes (collectively BTEX); fuel oxygenates: methyl tert butyl ether(MTBE), di-isopropyl ether (DIPE), ethyl tert butyl ether (ETBE), tertiary-amyl methyl ether (TMAE) and tertiary butyl alcohol (TBA); and fuel scavengers: ethylene dibromide (EDB) and 1,2-dichloroethan (1,2-DCA). The Work Plan was approved by San Joaquin County Environmental Health Department (SJEHD) staff in a letter dated 21 January 2015, with the following conditions: • Limit the total depth of borings to 20 ft bgs, except the boring located in the tank pit, which should be limited to 40 ft bgs. Reduction in total boring depths is due to the depth to water in the subject area, which is approximately 10 ft bgs. • Add analysis for semi-volatile organic compounds by EPA method 8270 to the analytical list for a shallow tank pit sample, as the UST possibly contained waste fuel. Central Valley Water Board staff concur with SJEHD staff's approval of the Work Plan, and staff concur with the scope of work with the following additional conditions: 1. All conditions listed by SJEHD staff in its 2 January 2015 letter are adhered to. A copy of SJEHD staff's 2 January 2015 letter is attached for reference.
