Lawrence Livermore National Laboratory h . July 8, 1991 � � 4 JUL 210' 19'1 ENVIRONMENTAL HEALTH PERMIT/SERVICES Mr. Doug Wilson San Joaquin County Public Health Environmental Health Division Post Office Box 2009 Stockton, CA 95201 Re: Site 300 Second Quarter 1991 Inventory Reconciliation Report Dear Mr. Wilson: This is the quarterly Underground Storage Tank (UST) inventory reconciliation report required by Title 23, California Code of Regulations, Section 2644(e). The underground fuel storage tanks located at Site 300 are monitored according to the provisions of Alternative 5 (Title 23, CCR, Sections 2641 [c][5] and 2644 [e]). The two tanks subject to the Alternative 5 system are designated by tank number 879-G1U1 and 879-G2U1. Both tanks are used to supply gasoline to laboratory vehicles only. For the second quarter 1991, there was one variation that exceeded the allowable limits for tank 879-G2U1 (refer to Table 1). The reason for this variation is unknown. It is highly probable that the cause of this variation can be associated with the annual testing of the tank. As a future precaution, the tank will be stabilized longer after the annual leak testing prior to taking the initial dip stick measurement. There is no evidence that the aforementioned tank was leaking because the tank passed the annual leak test four days prior to this variation. In addition, the remaining daily reconciliations were within allowable limits. Enclosed is an Inventory Reconciliation Quarterly Summary Report Form for Second Quarter 1991 for your records. Also included is Table 1. which provides more detailed information that cannot be readily accommodated on the standard Summary Report Form.
