SSMPA Calls for Cleanup at Rocketdyne

  • A Cleanup that Does More Good than Harm
  • A Cleanup that Protects Our Surrounding Communities
  • A Cleanup that Preserves SSFL's Natural Habit and Wildlife
  • A Cleanup that Is "Doable” and Affordable
See SSMPA's Response to DTSC's Environmental Impact Report for SSFL Cleanup:

"DTSC must not be bound by arbitrary, politically-predetermined constraints, such as the 2010 Administrative Orders on Consent (AOCs), in its selection of effective and executable cleanup alternatives."

September 29, 2017: SSMPA’s Position on Cleanup of Santa Susana Field Lab

The Santa Susana Mountain Park Association (SSMPA) recommends that all responsible parties at the Santa Susana Field Lab (SSFL) execute a minimal impact risk-based cleanup, protective of human health and environment, to EPA’s recreational open space standard.  

SSMPA recommends against excessive cleanup of inert, non-hazardous waste; that is, against a cleanup with a risk that may far exceed the “risk” of leaving inert materials in place.

Which community organizations have already called for a
risk-based cleanup (not "background") at SSFL?

West Hills Neighborhood Council

Woodland Hills–Warner Center Neighborhood Council

The California Department of Toxic Substances Control (DTSC)

has oversight authority for the cleanup at the former Santa Susana Field Laboratory.

DTSC oversees the plans and activities of the three parties responsible (RPs) for the cleanup:


U.S. Department of Energy (DOE)

Boeing Co.


Early August 2013: NASA released a statement (DEIS) on the impacts of its plans for completing the cleanup of its land (~450 acres) at Santa Susana Field Lab (SSFL).

Early September 2013: Santa Susana Mountain Park Association (SSMPA) posted a draft version of its thorough evaluation of NASA's statement.

Mid-September 2013: Chatsworth Neighborhood Council and West Hills Neighborhood Council passed resolutions consistent with SSMPA's evaluation

Late September 2013: SSMPA posted its final version of its evaluation of NASA's statement. SSMPA sent its evaluation to NASA officials and to 35 local political officials and agencies.

Bottom Line: Back to the drawing board

 NASA must acquire from California's Department of Toxic Substances Control (DTSC) important missing information, and NASA must issue a corrected, comprehensive DEIS that provides decision makers adequate information to make an informed decision on how the cleanup should proceed.

Subject:Santa Susana Cleanup Effort Is a Mess

Dear Michael Hiltzik:

I read your column this morning regarding "Santa Susana toxic cleanup effort is a mess".

You are correct. 

Unfortunately, you, like many others, have listened to a one-sided view as reported by Consumer Watchdog. Their alleged facts are very skewed and misrepresented. Past and recent testing have shown that there is not a higher cancer risk for residents living within 2 miles of the SSFL. On a personal note: My family, including three young children, in the late 1970's lived at the bottom of Runkle property in Simi Valley, the SSFL watershed area, and more recently for twelve years on Woolsey Canyon, West Hills. After living on both sides of the SSFL within 2 miles, in different time periods, my family and I are cancer-free and healthy.

The Consumer Watchdog group works on the human fear factor so that a responsible cleanup might not happen. The radical clean up to background will require more than ten years of truckloads, minimum of 80,000 truckloads, of soil and rocks being excavated and hauled out causing more health risks versus a technical remediation as Boeing has been conducting for years. Half of the San Fernando Valley is a Super Fund site because of contamination from gas stations, dry cleaners using chemicals, machine shops and aerospace industry. No one is advocating demolishing all structures and excavating the soil in the eastern half of the San Fernando Valley.

Many of us are working to stop the insanity, save a thriving and important wildlife corridor, preserve Native American historical districts and historical rocket engine test stands. We want a clean up, but a responsible cleanup that doesn't hurt the environment.

If you would like to know the real facts, not hyperbole, about the contamination, the clean up in process, and the best scenario to ensure a risk-based assessment of the cleanup, you are invited to attend the next Community Advisory Group (CAG) meeting or attend a tour of the SSFL so you can learn more about the site and this natural wonderland. Website information about the SSFL cleanup: and John Luker <>, SSMPA Vice President, will be happy to discuss the SSFL cleanup and advise you of the next CAG meeting and SSFL tour.
