Szeplaerl Pesti <br /> Page 2 <br /> PHS/EHD does not agree with the conclusion presented in the PAR <br /> that "No further investigation or remediation of adsorbed-phase <br /> hydrocarbon constitutes in the soil appears warranted at this <br /> time. " PHS/EHD requested further investigation of the on site/off- <br /> �site soil contamination.' The groundwater remediation proposal <br /> within the PAR included periodic pumping, activated carbon <br /> treatment and discharge of treated groundwater under a National <br /> Pollutant Discharge Elimination System (NPDES) permit. <br /> F Proposed soil and groundwater remedial options/additional <br /> investigation should be included in a draft Final Remediation Plan <br /> (FRP) . Prepare an executive summary/abstract of your draft FRP, <br /> pursuant to Section 280.67 Subpart 17 of 40CFR of the Federal <br /> Register. Please submit three copies of the draft FRP and <br /> executive summary/abstract to PHS/EHD by December 20, 1991. <br /> if you have any questions or comments contact Mary Meays, EHS, of <br /> my staff at (209) 468-3441. <br /> Jogi Khanna M.D. , M.P.H. <br /> Health O cer <br /> f <br /> a ie A.
