In response to the EHD letter dated 19 February 2015 recommending <br />installation of six borings to test several possibilities, CRA now proposes to advance three <br />shallow soil borings (B-1, B-2 and B-3) to depths of first groundwater [approximately six feet <br />below surface grade (bsg)] to collect soil samples for laboratory analysis to address issues <br />outlined in the 19 February 2015 EHD letter and the original Site Assessment Work Plan (WP) <br />dated 22 December 2014. Details for advancing the borings are provided in WP. <br />Although the EHD believes it to be more cost efficient to advance six borings to six feet bsg and <br />collect data to address several issues as outlined in the 19 February 2015 EHD letter, the three <br />proposed borings by CRA in VVPA will provide data on the possible contamination 'fairway' and <br />perhaps provide evidence of natural attenuation from B-1. To move the project forward, the <br />El-ID approves the three proposed borings, but notes that others may eventually be needed. <br />For your information, the EHD will not enter into a Local Oversight Program (LOP) contract with <br />the State Water Resources Control Board for the next fiscal year (2015-2016). As of 01 July <br />2015, the EHD will no longer be the lead agency for LOP sites. The EHD will continue to issue <br />the permits for monitoring well and soil boring installations and destruction of all wells and <br />borings at these sites. The EHD will be handing all active LOP cases over to Central Valley <br />Regional Water Quality Control Board (CVRWQCB) to provide oversight and eventual closures <br />of these cleanup cases. <br />The contacts for your site at CVRVVQCB will initially be: <br />Cori Condon at (916) 464-4619 or ccondonAwaterboards.ca.dov, <br />Jim Barton at (916) 464-4615 or jim.bartonAwaterboards.ca.gov, and <br />Vera Fisher at (916) 464-4792 or vera.fischer@waterboards.ca.dov.
