To date,this workplan has not been received by County or <br /> Regional Board staffs. It is our understanding that a large volume of gasoline remains in site soils, and <br /> the on-site water supply well does not have a sanitary seal. An investigation is required to identify the <br /> extent and concentration of groundwater contamination. <br /> By 5 June 2000,you must submit a workplan describing your proposed plans to sample and analyze the <br /> groundwater at the site. Site investigation work must begin by 17 July 2000, and a report of findings <br /> must be submitted to the Regional Board and San Joaquin County Environmental Health Division by <br /> 21 August 2000. All samples must be analyzed for TPHg and BTEX by EPA Methods 8015/8021 or <br /> 8260B, and for all fuel oxygenates, ethanol,methanol, 1,2-DCA, and EDB by EPA Method 8260B. <br /> The required"workplan" and the"report of findings"are technical reports as described in Section 13267 <br /> of the California Water Code, which states, in part <br /> "(b)(1) In conducting an investigation specified in subdivision (a), the regional board may <br /> require any person who has discharged, discharges, or is suspected of discharging, or who proposes <br /> to discharge waste within its region...shall f rnish, under penalty ofperjury, technical or monitoring <br /> reports which the regional board requires. The burden, including costs, of these reports shall bear a <br /> reasonable relationship to the need for the report and the benefits to be obtained from the reports. " <br /> Failure to submit the requested technical reports could lead to fines authorized by Section 13268 of the <br /> Water Code,which states: <br /> "(a)Any person failing or refusing to furnish technical or monitoring program reports as <br /> required by subdivision (b) of Section 13267...is guilty of a misdemeanor and may be liable civilly in <br /> accordance with subdivision (b). <br /> California Environmental Protection Agency <br /> ped RecycledPaper <br />
