Box 8307 PERMIT/SERVICES <br /> Stockton, CA 95208 <br /> DOCUMENTS REVIEW, MOORE TRUCK LINES, 3400 NEWTON ROAD, STOCKTON <br /> SAN JOAQUIN COUNTY(RB #391007) <br /> 1 reviewed Ground Water Monitoring Report— First Quarter 2011 (Report), received 11 June 2011 from <br /> your consultant Advanced GeoEnvironmental, Inc. The Report provided the groundwater monitoring <br /> results of one monitoring well (MW-1) sampled on 22 February 2011 (grab sample) and 11 March 2011 <br /> (full purge). The grab sample results were non-detect, while the full purge sample concentrations were <br /> total petroleum hydrocarbons as gasoline (TPHg), 140 micrograms per Liter (ug/L) and methyl tert butyl <br /> ether (MTBE), 120 ug/L. The results demonstrate that petroleum hydrocarbon concentrations have <br /> declined since February 2008. The Report recommends closure and well abandonment. <br /> I also reviewed the Report-referenced 30 August 2004 Closure Summary Report and 31 October 2008 <br /> Additional Site Assessment Report for content related to Regional Board case closure requirements. <br /> Please provide the following documents and supplemental information by 30 July 2011, to continue the <br /> closure process. Additional directives will be provided after receipt and my review. <br /> • A draft one page public notice in MS Word for public participation, by email to me. <br /> • A list of property owners and tenants within 500' of the Site, <br /> • a parcel map of the site and neighboring properties, and <br /> • A letter report containing the following additional information required for site closure: <br /> 1. The estimated time for TPHg and MTBE in MW-1 to reach water quality goals, <br /> 2. Mass estimates (initial and residual) for groundwater, and <br /> 3. A risk evaluation for soil, soil vapor and potential threats to nearby domestic wells <br /> If you have any questions, you can contact me at (916) 464-4615 or by e-mail at <br /> ib rton waterboards.ca. ov. <br /> :'James L.L.
