In light of back-to-back lawsuits that stalled construction, state water regulators have granted the Santa Clarita Valley Sanitation District more time to complete its four-year plan to reduce the amount of chloride discharged into the Santa Clara River watershed.

On March 12, the Los Angeles Regional Water Quality Control Board issued a tentative time schedule order, giving sewer officials a three-year extension to complete its plans.

Sewer officials were able to convince the board that lawsuits filed by an SCV group of ratepayers, called the Affordable Clean Water Alliance (ACWA), stopped it from working on the plan. The group challenged the district’s assessment of the impacts the chloride plan would have on the environment.

“Regarding the delays caused by the lawsuits, we are asking for an extension to January 2022,” Bryan Langpap, spokesman for the Santa Clarita Valley Sanitation District, said Monday

“Our chloride-compliance project was delayed due to legal challenge,” he said. “Because of the delay, we are not able to meet various compliance deadlines.”

Regional water officials agreed.

“We have been working with the Los Angeles Regional Water Quality Control Board, the regulator for the chloride limit, to demonstrate that these delays were beyond our control and that we have made our best effort to comply,” Langpap said.

The extension is scheduled to be finalized May 9.

Until then, the public has a chance to weigh in on the decision. Written comments must be received at the regional board’s office at 320 West 4th St., Suite 200, Los Angeles, 90013, by 5 p.m. Wednesday.

Comments may also be made at a public hearing scheduled 9 a.m. Thursday, May 9 in the City of Agoura Hills, 30001 Ladyface Court, Agoura Hills, 91301

If the TSO is approved and the SCV Sanitation District meets the TSO requirements, the SCV Sanitation District and its ratepayers will avoid regulatory fines.

In February, sewer officials announced they were scuttling recycled water plans because of the lawsuits.  

They also said the civil suits threw them off schedule to reduce salty chloride as promised to state officials in October 2014.

The Sanitation District, a Los Angeles County entity with two local representatives that is responsible for regulating local effluence, was mandated to reduce the amount of chloride, or salt, that discharges from SCV treatment plants into the Santa Clara River, largely due to concerns by downstream farmers that chloride was damaging salt-sensitive crops such as strawberries and avocados.

The litigation by ACWA delayed compliance with the state-mandated chloride limit by two years and cost ratepayers an additional $5 million, Grace Robinson Hyde, the chief engineer and general manager of the SCV Sanitation District, said in February.

“And, to be very clear,” she said, “all of the legal and resulting costs incurred to date, as well as those potentially incurred in (the) future, have been and will be borne by the ratepayers.”
