From  NASA's Comparative Analysis  of

Background versus Risk-based Cleanup Scenarios

for the Soils at Santa Susana Field Laboratory

"The more aggressive cleanup of the site that would occur under the background cleanup (more soil removal, more trucks entering the site, more emissions, more road miles, more soil to dispose of in landfills, etc.) could result in an increase in traffic accidents and spills and more habitat modification, as well as disturbance of wildlife and more impacts to archeological resources, all of which might result in reduced net benefits when compared to the risk‐based cleanup scenario." p. 5-1  

SSMPA calls for SSFL Cleanup target date to be pushed back. 


SSMPA's mission is to preserve and protect the Simi Hills, Santa Susana Mountains, and regional open space.
