610 HUNTER , STOCKTON <br /> FARMER' S PROPERTY <br /> PAGE 2 <br /> • Installation of a Gast 2567-P132-T908X rotary vane compressor with maximum of 20 <br /> pounds per square inch pressure and 18 standard cfin. <br /> • Installation of associated subsurface (2 feet bsg) and surface piping, meters, and <br /> control instrumentation <br /> • Construction of a shed to preclude public access and reduce noise. <br /> • Sampling and maintenance of the system. <br /> COMMENTS AND CONDITIONS: <br /> San Joaquin County Public Health Services, Environmental Health Division (PHS/EHD) <br /> provides the following comments and conditions on the proposed work: <br /> ATC calculated the volume of impacted soil to be treated at 245,430 cubic feet ( 10 feet of <br /> thickness at an area of 24,543 square feet), and estimated about 38,964 pounds of <br /> gasoline and 121 pounds of benzene in the soil. The contaminant mass in groundwater <br /> was not calculated since the lateral extent of the contamination has not been defined. <br /> This is required for interim remediation. <br /> A pore volume calculation for the SVE system using the pore volume exchange rate and <br /> the porosity of the soil being treated must be submitted to PHS/EHD by December 24, <br /> 2001 . PHS/EHD recommends that the system achieve one pore volume of soil vapor <br /> extraction daily. If additional work is required to accomplish this an addendum to the <br /> work plan should be submitted. Submit any additional information and work plan <br /> addendum with the pore volume calculation. <br /> REASONS FOR DISAPPROVAL OF THE WORKPLAN (H&S 25299.372 <br /> subd.(C) (3) .) : <br /> None <br /> DATEDNOV 2`Z 20 1BY JeffreyWong&SeniorHS LOP/Site Mitigation Unit IV <br /> c: Drew Van Allen - ATC Associates Inc.
