CLOSURE SOLUTIONS, INC. <br /> .;!AR 0 4 2010 <br /> March 3, 2010 <br /> ENVIRONMENT HEALTH <br /> Mr. Anand Mamidi PERMIT/SERVICES <br /> California Regional Water Quality Control Board—Central Valley Region <br /> 11020 Sun Center Drive, Suite 200 <br /> Rancho Cordova, California 95670-6114 <br /> Subject: Sampling and Reporting Clarification <br /> Flag City New West#103 <br /> 6437 West Banner Street <br /> Lodi,California <br /> Order No. 115-2008-0085-013 <br /> Dear Mr. Mamidi: <br /> On behalf of New West Stations, Inc. (New West), Closure Solutions, Inc. (Closure Solutions) <br /> has prepared this Sampling and Reporting Clarification letter for the Flag City New West <br /> facility, located at 6437 West Banner Street, in Lodi, California (the Site, Figure 1). Closure <br /> Solutions has prepared this letter to document verbal changes to the sampling requirements <br /> included in the Notice of Applicability (NOA) during the phone conversation on February 25, <br /> 2010. During the conversation, you made the following changes to the NOA: <br /> 1) Upstream receiving water sampling: <br /> You stated that the upstream receiving water body DOES NOT need to be monitored for flow, <br /> pH, dissolved oxygen, electrical conductivity, temperature, total dissolved solids and turbidity <br /> as indicated in Attachment E Table E-6. You stated that the upstream receiving water DOES <br /> need to be monitored for hardness on a quarterly basis. <br /> 2) Downstream receiving water sampling: <br /> You indicated that the downstream receiving water body must be sampled on a quarterly basis <br /> for all the constituents listed in Attachment E Table E-7, plus hardness, which is not included in <br /> Attachment E Table E-7. <br /> Historically, neither upstream nor downstream receiving water body samples were collected <br /> from White House Slough on a regular basis, in accordance with the recommendations of Mr. <br /> Michael Negrete. Mr. Negrete indicated that White House Slough likely contained constituents <br /> of concern due to agricultural operations in the immediate vicinity of the water body, and that <br /> sampling the receiving water body did not serve a useful purpose. <br /> 2151 Salvio Street -Suite 301 < Concord, CA 94520 <br /> (800) 988-7880 <br />
