The workplan proposes the expansion of the <br /> groundwater monitoring network at the winery in accordance with Provision H.1.b of Waste <br /> Discharge Requirements (WDRs) Order R5-2012-0103, which was adopted on 12 April 2013. <br /> Six shallow-interval groundwater monitoring wells (MW-1 through MW-6) currently exist at the <br /> site to monitor conditions surrounding the initial 30 acres of LAAs. The original workplan dated <br /> 28 June 2013 proposed the installation of one additional groundwater monitoring well (MW-7) <br /> north of LAA No. 2, based on a general north-northeasterly direction of groundwater flow. <br /> Per our review of the original workplan, one additional monitoring well was requested <br /> downgradient of LAA No. 4 in a letter dated 12 July 2013. The revised workplan provided a <br /> modified site plan (Figure 3 Revised) showing the proposed location of two monitoring wells <br /> (MW-7 and Ilii downgradient of LAA No. 2 and LAA No. 4, respectively. With the inclusion <br /> of MW-8 as part of the proposed scope of work, the workplan is hereby approved. Upon <br /> completion of additional monitoring well installations, monitoring of the existing and new wells <br /> shall be conducted in accordance with Monitoring and Reporting Program R5-2013-0028. <br /> Please submit the Monitoring Well Installation Report by 1 July 2014, as required by the WDRs. <br /> If you have any questions or need further clarification, please contact me at (916) 464-4616 or <br /> sarmstro ng(.awaterboards.ca.gov. <br /> SCOTT ARMSTRONG, P.G., C.HG. <br /> Engineering Geologist <br /> Waste Discharge to Land Permitting Unit <br /> cc: Rodney Estrada, San Joaquin County Environmental Health Department, Stockton <br /> Alicia Stamps, Kennedy/Jenks Consultants, San Francisco <br /> VA L E.
