Please submit a <br /> copy of their protocol to the EHD so that it may be compared to the ITRC guidance <br /> document and the Central Valley Regional Water Quality Control Board (CVRWQCB) <br /> Waste Discharge Requirement (WDR) evaluation checklist or advise the EHD that you <br /> will be following ITRC and CVRWQCB guidelines for-conducting BSTs. <br /> The EHD has evaluated the construction specifications included in the plan for the <br /> additional monitoring wells. Although the existing monitoring wells were installed with <br /> 25-foot long screened intervals, the EHD will not permit additional wells to be <br /> constructed with these long screened intervals. Historical depths to ground water at this <br /> site show that the most shallowest depth to first ground water is 8 feet below ground <br />'i surface and the deepest is 13 feet. A ten or fifteen foot screen in the proposed <br /> monitoring wells is sufficient. if you can justify the need°for ground water sampling at <br /> deeper intervals, then additional wells can be installed adjacent to these (clustered). If <br /> you advise the EHD that 25-foot screened intervals will not be installed,then the plan <br /> can be approved without a revision. <br /> You may email Mr. lnfurna with you' acknowledgements requested or submit a revised <br /> plan. Mr. lnfurna can be reached by electronic mail at minfurna(a)sicehd.com.
