Lawrence Livermore National Laboratory - Site 300
Tracy, San Joaquin County, California
|
|
Office: Oakland Operations Office
Size:
7,000 acres (10.1 square miles)
NPL Status:
Placed on the NPL on August 30, 1990.
Mission:
The LLNL was established in 1952 to function as a national scientific and
technical resource for the nuclear weapons program and other programs of
national interest. LLNL performs research, development, and testing associated
with the nuclear design aspects of all phases of the nuclear weapon life cycle.
The Laboratory consists of two noncontiguous parcels, the Livermore Site and
Site 300. Site 300 is used for high explosives testing.
Overview of Environmental Conditions:
Contamination of onsite groundwater and soil with tritium and trichloroethylene
and high explosive compounds.
CERCLA/RCRA Remediation Funding in FY 95: $9,220,000

Progress in Reaching Interagency Agreement
An integrated (CERCLA/RCRA) FFA was negotiated and signed between DOE, EPA
Region IX, the California EPA's Department of Toxic Substance Control, and the
Central Valley Regional Water Quality Control Board in June 29, 1992. In
February 1994 a revised Appendix A (schedule of deliverables) to the FFA was
approved by EPA.
Specific Cost Estimates and Budgetary Proposals Involving Each Interagency
Agreement
Funds budgeted for environmental restoration to support the milestones in the
FFA at the LLNL-Site 300 total $10.5 million of appropriated funding for FY 96
and $9.8 million for FY 97 according to the request in the President's Budget.
Public Comments Regarding Interagency Agreements
All stakeholders and interested parties have been involved in the development
of the FFA and subsequent revisions.
Progress in Conducting Remedial Investigations/Feasibility Studies
Under the terms of the FFA and at the request of the regulatory agencies, the
Site 300 Site Wide Remedial Investigation (SWRI) Report was prepared. The final
SWRI Report was submitted to the regulators on March 10, 1994.
DOE, LLNL, and regulatory agency personnel have worked together to
"re-engineer" the CERCLA process to expedite cleanup at portions of LLNL-Site
300 that present risks to human health and the environment. The areas of
highest priority are the GSA, Building 834, and Building 832 Canyon. GSA and
Building 834 are going through the standard CERCLA process of FS, PP, Public
Meeting, and ROD. The draft and final FS for the GSA OU and the final FS for OU
3/Pit Complex were submitted in FY 95. The Interim ROD for the Building 834 OU
was also completed in FY 95. Building 832 Canyon is in the subsurface
investigation phase, and the appropriate CERCLA path will be chosen on
completion of the investigation.
Progress in Conducting Remedial Actions
The Interim Groundwater Facilities at the Eastern and Central GSA
have continued to operate, and the Interim Soil Vapor Extraction Facility at
Building 834 was restarted. At GSA, the offsite plume was significantly pulled
back and offsite contamination was reduced.
