This letter is the second <br /> quarterly inventory reconciliation report filed for the Lawrence <br /> Livermore National Laboratory Site 300 facility. It covers the <br /> period from April through June, 1988. The report was delayed due <br /> to the discovery of inventory reconciliation procedural <br /> deficiencies at one of the buildings at the Site 300 facility. A <br /> review of equipment and procedures is currently underway. The <br /> report for the third and fourth quarters will follow in sixty <br /> days. <br /> Underground storage tanks subject to inventory reporting at the <br /> Site 300 facility are used as fuel supplies for emergency <br /> generators and motor vehicles. <br /> Emergency generator fuel supplies are registered with the <br /> State Water Resources Control Board as systems 805-41D, 814-41D, <br /> 827-12D, 830-11D, 834-11D, and 836-41D. These systems are <br /> monitored according to Alternative 7: weekly tank gauging and <br /> annual tank testing. Reconciliation of weekly tank gauging shows <br /> quantity variations to be within allowable limits for the second <br /> quarter of 1988. <br /> Motor vehicle fuel supplies are registered as systems 879-11G <br /> (879-G1U1) and 879-12G (879-G2U1) . Lawrence Livermore National <br /> Laboratory now identifies these tank systems as 879-GlU1 and <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 />
