Lawrence Livermot National Laborator <br /> ® Y <br /> October 31,1989 <br /> EcE I <br /> � <br /> Ms. Laurie Cotulla NOV 7 9939 <br /> San Joaquin County Public Health Services <br /> Environmental Health Division ENVIRONMENTAL HEALTH <br /> Post Office Box 2009 PER MIT%SERVi CES <br /> Stockton,CA 95201 <br /> SUBJECT: Site 300 Inventory Reconciliation Report, 3rd Quarter 1989 <br /> Dear Ms. Cotulla, <br /> In-use underground storage tanks constructed before January 1,1984,are subject to the <br /> leak monitoring alternatives defined by California Code of Regulations Title 23, Chapter 3, <br /> Subchapter 16,Underground Tank Regulations,Article 4,Section 2641. Underground storage <br /> tanks monitored according to alternatives that include fuel quantity measurements are to report <br /> the results of these measurements quarterly. This letter is the quarterly inventory <br /> reconciliation report filed for the Lawrence Livermore National Laboratory (LLNL) Site 300 <br /> facility for the third quarter of 1989. It covers the period from July through September, 1989. <br /> Underground storage tanks subject to inventory reporting at the Site 300 facility are <br /> used as fuel supplies for emergency operators and motor vehicles. <br /> Emergency generator fuel supplies are registered with the State Water Resources <br /> control Board a systems 805-41D,827-12D,834-11D and 836-41D. LLNL now identifies these <br /> tanks as 805-D1U1, 827-D2U1,834-D1U1, and 836-D1U1,respectively. These systems are <br /> monitored according to Alternative 7: weekly tank gauging and annual tank testing. <br /> Reconciliation of weekly tank gauging shows quantity variation to be within allowable limits <br /> for the third quarter of 1989. <br /> There are three motor vehicle fuel supply tanks that are currently identified by LLNL <br /> as 879-G1U1,879-G2U1,834-D1U1. Tank 879-GlUl was previously registered as 879-11G and <br /> 879-G2U1 was registered as 879-12G. These systems are monitored by the requirements of <br /> Alternative 5: daily inventory reconciliation,annual tank testing,and continuous operation of <br /> pipeline leak detectors. <br /> Daily inventory reconciliation of tank gauin$showethaf frkiir fan1r.had volume <br /> variations that exceeded allowable limina 1 suiiitharizes the variations that excc6 cl`-' <br /> t1we'9116wabk limit for tanks 805-D1U1, 827-D2U1, 834-D1U1,and 836-D1U1."The allowable <br /> limit on all of these tanks was exceeded due to filling up the tanks to full capacity in order to <br /> conduct annual precision test. A test report from Gary Peters Enterprises for each of the tanks <br /> listed shows they passed a precision test on dates as shown. <br /> An Equal Opportunity Employer•Universityof California•P.O.Box 808 Livermore,California 94550•Telephone(415)422-1100•Twx 910-386-8339 UCLLL LVMR <br /> i <br />
