j STA'T`E OF CALIFORNIA PETE WILSON, Governor <br />CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD �o0F <br />CENTRAL VALLEY REGION <br />3443 ROUTIER ROAD, SUITE A <br />Sacramento, CA 95827-3098 <br />PHONE: (916) 361-5600 <br />FAX (916) 361-5686 <br />y m, <br />31 October 1991 <br />Mr. Benjamin Hall <br />Musco Olive Products <br />17950 Via Nicolo Road <br />Tracy, CA 95 <br />APPROVAL OF CONSTRUCTION QUALITY ASSURANCE REPORT FOR POND 8, MUSCO OLIVE <br />PRODUCTS, SAN JOAQUIN COUNTY (CASE# 2743) <br />Our staff has reviewed Specifications and Drawings for Pond B (September <br />1990), Design Operations Report (February 1986), Addendum to Design Operations <br />Report (March 1986), Preliminary Quality Assurance & Control Report (24 May <br />1991) and the 24 September 1991 Addendum No. 1 to the Construction Quality <br />Assurance (CQA) report. The enclosed Memorandum contains staff comments on <br />the Construction Quality Assurance report. I concur with the staff conclusion <br />that the required in situ permeability testing was not completed. <br />The flexible membrane liner and leachate collection system could be removed <br />and in situ testing could still be done to verify construction to the required <br />permeability. However, winter rains would likely make it impossible to <br />complete the testing this winter, we understand that Musco needs to use the <br />pond immediately. Moreover, staff is of the opinion that the clay liner is <br />probably constructed to meet the permeability requirement. Therefore, I <br />approve the construction of Pond B at Musco Olive Products, Tracy. <br />This approval should not be construed as an indication that we will accept <br />similar CQA in the future. In the future, the CQA plan must be submitted and <br />approved prior to construction. <br />If you have any questions, please <br />Robert Evans (916) 361-5737. <br />WILLIAM H.
