Don’t Fear the CleanUp - It can be Achieved Properly
and SAVE Protected Species.
It will also lessen the toxins reaching off-site
For the Health & Safety of the Surrounding Communities

| Careful Consideration of the Protected Oak Trees During Remediation |

In early October 2010, NASA began soil removal activity on land it administers in Area II near a former incinerator and related ash pile (which burned non-hazardous wastes - from the mid-1950s through the 1970s) and sewage treatment plant (operational from 1961 to 1987). Soil removal in 2010, which targeted dioxin, was conducted in areas containing some oak trees. “We got at the soil we needed to with very minimal disturbance to the surrounding environment. That was our goal,” said Randy Dean, a CH2MHill contractor to NASA.
It was like watching a choreographed performance. Crews working in unison: workers with shovels carefully digging and loosening the top layer of soil, closely shadowed by workers wielding an industrial vacuum whisking away the soil to an awaiting closed container truck. “In this manner, no oak tree roots were exposed or damaged during the soil removal,” added Dean. All heavy equipment (small excavator and transport vehicles) stayed well beyond the oak tree drip line.

NASA’s work in removing soil contamination and protecting surface water quality continued during 2011 as part of the Interim Source Removal Action (ISRA). Phase I in the Area II Landfill vicinity was completed in 2009. Phase II near a former incinerator and related ash pile began in 2010 and continued in 2011. Phase II work has included excavation of approximately 273 cubic yards of soil in 2010 and an additional 1,156 cubic yards of soil in 2011 that was disposed of at Waste Management’s landfill in Lancaster, CA. Phase II work is planned to be completed in 2012 and will be followed by a Phase III. The ISRA is being conducted at SSFL under the direction of the Los Angeles Regional Water Quality Control Board (LA-RWQCB).
