By allowing TOC ninety days to study remedial <br /> alternatives and to submit the findings, PHS-EHD expected to review data that would <br /> show which viable groundwater remediation method would be more cost-effective. <br /> Only one method (pump and treat) was proposed and the costs associated with this <br /> method were not provided. This CAP supplement is inadequate since feasibility studies <br /> for two alternatives have not been performed and evaluated. <br /> Currently this site is being evaluated by the State Water Resource Control Board <br /> (SWRCB) Clean Up Fund (CUF) to determine if the site is in compliance with corrective <br /> action requirements. By submitting an inadequate CAP (supplement), you are not in <br /> compliance with PHS-EHD directives and you have jeopardized your ability to receive <br /> reimbursement for your required soil and groundwater remediation. <br /> You are hereby directed to submit to PHS-EHD by August 21, 1998 a soil and <br /> groundwater Corrective Action Plan that addresses and evaluates two <br /> alternatives for restoring and protecting the beneficial uses of the groundwater. <br /> TOC is to provide data that shows the most cost-effective remedial method based upon <br /> field and feasibility tests performed on existing or newly installed equipment. Complete <br /> costs and a time schedule are to be included in the CAP. <br /> A Division of San Joaquin County Health Care Services <br />
