Sandia National Laboratories/California
Livermore, Alameda County, California

|
Office: Albuquerque Operations Office
Size:
413 acres (0.6 square mile)
Mission:
Established in 1956 to provide support services to the neighboring Lawrence
Livermore National Laboratory, Sandia National Laboratories/California's
initial mission was to provide ordnance engineering services to Lawrence
Livermore National Laboratory. Current programs being carried out at Sandia
National Laboratories/California include nuclear weapons systems development
and combustion, solar, and fusion research. The site was developed initially by
the U.S. Navy in 1942 and later relinquished for DOE activities in 1956.
Overview of Environmental Conditions:
Soil and groundwater contamination from a diesel fuel leak and from historical
land disposal practices.
CERCLA/RCRA Remediation Funding in FY 95: $2,780,000
|
Remediation of environmental conditions at Sandia National
Laboratories/California is being addressed under authority of a State of
California Cleanup Order.
Specific Cost Estimates and Budgetary Proposals
Funds budgeted for environmental restoration at Sandia National
Laboratories/California total $2.8 million of appropriated funding for FY 96
and $2.6 million for FY 97 according to the request in the President's Budget.
Progress in Conducting Remedial Actions
On October 15, 1987 a PA/SI was submitted to EPA in response to CERCLA Section
120 requirements. To date, EPA has not completed a Hazard Ranking System
evaluation for this site.
In December 1989, the State of California RWQCB issued a Site Cleanup Order
(No. 89-184) to DOE and the Sandia Corporation. This order modified Order
88-142 requiring the consolidation of all site work to be accomplished by the
Sandia Corporation and DOE, and set forth provisions and specifications for
development and implementation of soil cleanup alternatives for identified
areas of soil and groundwater pollution. Four areas of potential soil and
groundwater pollution were identified in the Cleanup Order: Trudell Auto Repair
Shop, Fuel Oil Spill, Navy Landfill, and Miscellaneous Sites. RIs at all four
sites were completed in 1991.
Regarding the cleanup of the Fuel Oil Spill site, authorization to proceed as
recommended with an in-situ bioremediation pilot study was provided in December
1990. The remedial action plan for the Fuel Oil Spill was submitted to the
State of California for review in March 1992. In October 1993, the state
approved the use of the bioremediation pilot study for cleanup. An interim
remedial measure is being implemented to protect groundwater while the
bioremediation pilot study is being constructed and implemented. Construction
of the pilot project was completed in FY 95. The first injection phase of the
bioremediation phase began in June 1995.
The Navy Landfill Solid Waste Water Quality Assessment Test report was
submitted for review on June 29, 1990, as scheduled, recommending the "No
Action Alternative." Groundwater monitoring continued through 1994 to address
RWQCB concerns. The RWQCB gave permission in November 1994 to prepare a closure
plan for the Navy landfill. Acceptable closure should consist of slope
stabilization to be compatible with explosive magazines at the base of the
landfill.
The Miscellaneous Sites investigation found contaminants present in
concentrations far below regulatory guidelines. The report was submitted to the
State of California recommending "no further action." The RWQCB agreed to
closure of the assessment phase in 1994; no remedial activities were necessary.
Remedial activities associated with the Trudell Auto Repair Shop were completed
in September 1990 and the site was closed in December 1990. (DOE procured the
land on which the repair shop was located to serve as a buffer zone for the
protection of site operations.)
