ISRA Excavation and Removal of "ELV" Soils Has Begun

Published: 11/13/2012

To undertake some Interim Source Removal Action (ISRA) activities in the Expendable Launch Vehicle (ELV) Service area in NASA-administered Area II before the onset of seasonal rains, NASA has begun excavation and removal of some surface soils. The area being excavated is the southwestern portion of the ELV-1C area.

This action is taken at the direction of the Los Angeles Regional Water Quality Control Board (RWQCB) and with the concurrence of the Department of Toxic Substances Control (DTSC). Soils within this portion of the ELV-1C area have been sampled, analyzed, and compared to the ISRA cleanup goals approved by the RWQCB. Any soils with concentrations above these goals will be excavated. Additionally, waste characterization soil samples were analyzed in the ELV-1C area and, with the written approval of DTSC, these soils were screened against the Radiological Trigger Levels (RTLs) provided by EPA in December 2011. The soil sample results in the southwestern portion of the ELV-1C area yielded no radionuclide results at or above the December 2011 RTLs. The soils will be transported for disposal at the Waste Management Landfill in Lancaster, California, which accepts non-hazardous soils.

This decision reflects cooperation among NASA, DTSC and the RWQCB. The parties concluded that, because the EPA’s recommended RTLs are a more conservative screening level than the expected radiological lookup tables (to be finalized next year), and because the southwestern ELV-1C soils results are below the RTLs, NASA should begin this important ISRA work this year, in the attempt to remove approximately 600 cubic yards soil before winter rains.

NASA Has Received Closure Certification from DTSC for Three Groundwater Treatment Units

Published: 11/9/2012

NASA has received Closure Certification from the Department of Toxic Substances Control (DTSC) for three Hazardous Waste Management Units on NASA-administered property at Santa Susana Field Laboratory. The Bravo Groundwater Treatment Unit (GWTU), the Delta GWTU, and the RD-09 GWTU, including the associated pipelines between the groundwater extraction wells and the GWTUs are considered closed by DTSC under the Resource Conservation and Recovery Act (RCRA).

Update on NASA’s National Environmental Policy Act Compliance for Santa Susana Field Laboratory

Published: 7/18/2012

NASA remains committed to a proposed cleanup to background that will meet the Administrative Order on Consent between DTSC and NASA.

We received comments from Senator Boxer and the Council on Environmental Quality regarding the evaluation of alternatives for the preparation of our Environmental Impact Statement. As a result, NASA has chosen to streamline its review in the Draft Environmental Impact Statement (DEIS) and analyze only the alternatives of (a) cleanup to background and (b) the “no-action” alternative.

The Final Environmental Impact Statement can be found on the Key Documents page.

SSFL FieldNOTE – May 2012

NASA's NEPA Community Informational Meeting - March 27, 2012

Published: 2/7/2012

This meeting will provide updates on the results of surveys and other data NASA is gathering as it prepares its Draft Environmental Impact Statement (EIS). The Draft EIS is expected to be provided to the public for review and comment in summer 2012. The SSFL EIS Factsheet describes the current SSFL EIS process.

The meeting will begin at 6:00 p.m. From 6:00 to 6:45 NASA experts will hold informal discussions at various displays that summarize the information and approach NASA is taking to prepare its Draft EIS. From about 6:45 to 8:00 NASA experts and NASA consultants will provide an update on the EIS impact analysis and related studies followed by Questions and Answers between NASA presenters and the public.

Following the Q&A, informal discussions may take place.

The meeting will be in Chatsworth on March 27, 2012:
6:00 p.m. – 8:30 p.m. at the Radisson Hotel Chatsworth
9777 Topanga Canyon Road
Chatsworth, CA 91311

Note: The hotel may only be entered when heading south on Topanga Canyon Blvd (TCB). To enter heading north, make a U-turn at Lassen St. The hotel entrance arises abruptly as you round the corner on TCB after you pass Lassen St.
