Box 808 <br /> Livermore, CA 94550 <br /> VOLATILE ORGANIC COMPOUNDS DETECTED OFF-SITE, UNIVERSITY OF CALIFORNIA, LAWRENCE <br /> LIVERMORE NATIONAL LABORATORY SITE 300, SAN JOAQUIN COUNTY - CASE NO. 2677 <br /> We have reviewed your 31 August 1988 work plan and time schedule prepared in <br /> response t0 our 24 August 1988 request® The work plan was to provide' an assess- <br /> ment of the extent, and the rate and direction of movement of the volatile organic <br /> compounds (VOCs) detected off-site of Lawrence Livermore National Laboratory' s <br /> Site 300. We remain concerned about the potential for the escaped VOCs to <br /> contaminate both Site 300 and private, off-site drinking water supply wells. <br /> The work plan and time schedule do not adequately respond to our concern. By, <br /> merely incorporating the characterization of the escaped VOC plume into the <br /> ongoing investigation in the General Services Area, you provide insufficient <br /> - - detail on yourspecificplans for the off-site work. Also, there is no justifi- <br /> cation to extend the schedule for conducting this important activity from January <br /> to September 1989. You should address this problem immediately and specifically. <br /> We expect to receive the required work plan and time schedule by 30 September <br /> 1988. The work plan must be directed specifically at characterizing the escaped <br /> VOC plume and providing interim containment and/or treatment, if necessary. IF <br /> you have any questions or comments, please call me at (916) 361-5653. <br /> MICHAEL HIGG <br /> Area Engineer <br /> MLH:gs <br /> cc: Mr. James T. Davis, U. S.
