An agreement has been reached regarding the cleanup of chemical pollution at the Santa Susana Field Laboratory that sets strict deadlines and financial penalties.

The state Department of Toxic Substances Control negotiated the enforcement order this summer with the Boeing Co., U.S. Department of Energy and NASA, and released the final agreement on Aug. 16.

The enforcement order, among other things, mandates the entities submit plans proposing cleanup measures for the chemical contamination at the 2,850-acre former rocket engine and nuclear test site south of Simi Valley.

State law gives the Department of Toxic Substances Control the right to issue such an order when it determines there "is or has been a release of hazardous waste or hazardous waste constituents into the environment from a hazardous waste facility," the order states.

"It describes in great detail the various things the respondents need to do in order to move from the situation we find ourselves in today, toward the completion of the cleanup," said Norman Riley, the department's project director for the Field Lab. "We want them to be very clear on what we want."

Cleanup of chemical contamination at the site is expected to be completed by June 30, 2017, Riley said.

The 74-page document sets a series of deadlines for work ranging from collecting water sample reports to submitting aerial photographs of the site.

Boeing, the Energy Department and NASA must adhere to the deadlines. Any violation of the order's demands will result in a $15,000 fine, per violation, per day.

The Department of Energy owns some facilities at the Field Lab, and its contractors carried out nuclear experiments, including the operation of several small nuclear reactors. One of those reactors had a partial meltdown in 1959.

The department is tasked with overseeing the cleanup of radioactive contamination at the site and will also be responsible for removing chemical pollution on 290 acres of the site where the agency conducted its work.

"We entered these negotiations in good faith," said William Taylor, a spokesman for the department.

"It is very typical to work with state and federal agencies on cleanups."

NASA administers some land at the Field Lab, which is owned by the federal government and operated by Boeing, which bought the Field Lab in 1996.

The aeronautics company owns the bulk of the land. A spokeswoman for the company said it is committed to cleaning up the Field Lab in a timely and thorough manner and will work with agencies overseeing the efforts.

The public will also be a part of the process as the entities carry out the order's demands. Once specific methods for removing the contamination are proposed by the entities, a public hearing will be held.

The Department of Toxic Substances Control will give final approval on which cleanup measures are adopted.

This is the second time the department has issued an enforcement order for the Field Lab.

The first order was issued in 1992, Riley said. "It was very brief and nowhere near the level of detail that you see in this order," he said.

The new order supersedes the previous one.

It also calls for quarterly progress reports from the entities and lays out rules for the swift cleanup of contamination that causes an immediate danger.

Dan Hirsch, co-founder of Committee to Bridge the Gap, a nuclear watchdog group, said the new order has teeth.

"I think it's acknowledging the last one didn't get the job done," he said. "One hopes that this is going to be different this time."
