W. HAYES FACILITY), 2005 NAVY DRIVE, STOCKTON, <br /> SAN JOAQUIN COUNTY(RB #390659) <br /> 1 reviewed the Workplan for Soil and Groundwater Investigation (Workplan), received <br /> 13 September 2011 from your consultant KR Environmental. The Workplan proposed sampling <br /> of the monitoring wells (MW-1 through MW-4) and advancement of four soil borings (SB-3 <br /> through SB-6) for a total of twelve (three per boring) soil samples and four grab groundwater <br /> samples, to monitor groundwater and provide additional data for investigation to support the <br /> conclusion for the source of petroleum hydrocarbons and chlorinated solvents reported in <br /> groundwater monitoring between the wash rack and the former waste oil tank pit. Soil and <br /> groundwater analyses will include hexane extractable material (oil and grease) by <br /> APHA/USEPA Method 1664A, total petroleum hydrocarbons as diesel (TPHd) by USEPA <br /> Method 8015M, and TPH as gasoline, benzene, ethylbenzene, toluene, xylenes, fuel <br /> oxygenates, lead scavengers, and volatile organic compounds by USEPA Method 82608. <br /> The Workplan is approved. Please provide, by email to the email address listed below, a <br /> schedule for the fieldwork and report submittal by 1 October 2011. Failure to properly <br /> characterize the source area with supportable data will result in issuance of a formal <br /> enforcement Order pursuant to Section 13267 or 13304 of the California Water Code, in order <br /> to move this UST case towards a timely closure.
