Lawrence Livermore National Laboratory - Livermore Site
Livermore, Alameda County, California
|
|
Office: Oakland Operations Office
Size:
811 acres (1.3 square miles)
NPL Status:
Placed on the NPL on July 22, 1987.
Mission:
The Lawrence Livermore National Laboratory (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, consisting of
two noncontiguous parcels (Livermore Site and Site 300), is also involved in
the following programs: inertial fusion, magnetic fusion, biomedical and
environmental research, isotope separation, and applied energy technology and
other research-related activities.
Overview of Environmental Conditions:
Contamination of groundwater and soil with tetrachloroethylene,
perchloroethylene, and trichloroethylene.
CERCLA/RCRA Remediation Funding in FY 95: $15,620,000

Progress in Reaching Interagency Agreement
DOE entered into an FFA with EPA Region IX and the State of California for
cleanup of the LLNL-Livermore Site. This FFA was executed on November 1, 1988
and became effective in February 1989. Significant emphasis was placed on the
renegotiation of FFA enforceable milestone deliverables this fiscal year. In
June 1994, EPA and the state agencies approved a revised schedule that
reprioritized activities to direct the focus on western and southern perimeters
where there is offsite contamination. A treatability study and groundwater
facility were added for Trailer 5475 where there are volatile organic compounds
and tritium contamination. The Treatment Facility 518 vapor extraction system
was also included in the schedule.
Specific Cost Estimates and Budgetary Proposals Involved in Each Interagency
Agreement
Funds budgeted for environmental restoration to support the FFA milestones at
the LLNL-Livermore Site total $12.7 million of appropriated funding for FY 96
and $12.7 million for FY 97 according to the request in the President's Budget.
Public Comments Regarding Interagency Agreements
No new comments on the FFA were received in FY 95. An IAG in the form of an FFA
became effective in 1989; as a result, a technical assistance group is in
place. This group continues to support community working group to review post
ROD documents and to provide input into the recent renegotiations and
priorities of the site remediation efforts.
Progress in Conducting Remedial Investigations/Feasibility Studies
The Draft Final FS was submitted to the state and EPA in December 1990 and the
proposed Remedial Action Plan was submitted in October 1991, in preparation for
the November 1991 public hearing on the proposed plan for onsite remediation
activities. A responsiveness summary for the public comments and final ROD was
approved by DOE in June 1992.
Progress in Conducting Remedial Actions
The ROD for the LLNL-Livermore Site was approved by DOE, EPA, and the State of
California in June 1992. The ROD called for cleanup of soil and groundwater
using seven treatment facilities and 24 initial extraction locations. In FY 95,
a draft Compliance Monitoring Plan was completed. In FY 95, Treatment Facility
518 was constructed and operation started. Currently, five treatment facilities
are in operation. Hydraulic control of the western offsite plume was
established in FY 95, including a dramatic decrease in offsite contaminant
concentrations. Additionally, a successful demonstration of the Dynamic
Underground Stripping Technology was performed at the Gasoline Spill Area,
which resulted in the removal of approximately 10,000 gallons of fuel
hydrocarbons.
In FY 95, Final Remedial Design Reports Numbers 5 and 6 were completed and
issued. Negotiations with regulators were conducted that reduced reporting
requirements. Treatment Facility F vadose zone remediation was completed and
groundwater pumping ceased for 6 months. Treatment Facility A North and
Treatment Facility B North pipelines were constructed and activated, and the
underground tank at Building 292 was sealed.
