The EHD has the following comments: <br /> 1. The remediation plan for the proposed ventilation system must be submitted to the San <br /> .Joaagtiin County Air Pollution Control District for approval: t <br /> 2. The remediation plan does not define what the "short-term vapor extraction pilot test" is, <br /> and how it will be conducted and evaluated for remediation of the site. <br /> 3. The remediation pian lacks precise locations and descriptions of the two ventilation wells. <br /> 4. The remediation plan does not address what corrective actions need to be taken to protect <br /> the public health,safety,and the environment in accordance to Title 27 California Code of <br /> Regulations(27 CCR)Section 20937(a)(4). <br /> 5. The gas control system described in the remediation plan has not been designed by a <br /> registered civil or mechanical engineer in accordance to 27 CCR 20937(a)(5). <br /> Pursuant to 27 CCR 20919 and 20937,the ETD does not approve the remediation plan submitted <br /> by URS. The passive venting of landfill gas through the use of ventilation wells is not a suitable <br /> remediation for the site. <br /> The EHD is requiring that an appropriate gas control.system be planned and designed for <br /> remedlation of the site as described in 27 CCR 20919 and 20937(a). <br /> The EHD is requiring that a revised remedlation plan be submitted within fourteen (14) days <br /> receipt of-this letter. <br /> If you have any questions,please contact Ted Tasiopoulos R.E.H.S.at(209)953-7698. <br /> i <br /> abert McC el on, upR.E,H.S. <br /> Environmental Health Department <br /> i <br /> CC: Jay Kamine,URS <br /> John Macorias,CIWMB,MS-20 <br /> i <br /> i <br />
