County officials urge EPA to quickly clean up DDT dumping off Palos Verdes Peninsula

The Los Angeles County Board of Supervisors will urge the U.S. Congress and the EPA to swiftly assess the environmental consequences and expedite cleanup of thousands of barrels of potentially toxic chemicals sitting on the ocean floor off the Palos Verdes Peninsula.

The supervisors unanimously voted to lobby the federal government on Tuesday, May 4, about a week after scientists announced they had discovered more than 27,000 barrels of what could be the banned pesticide DDT laying on the ocean floor between the Palos Verdes Peninsula and Catalina Island. It’s a revelation that has potentially catastrophic consequences for marine life.

“We are relying on the EPA,” said District 4 Supervisor Janice Hahn, who introduced Tuesday’s motion, “to hold accountable those who dumped barrels of toxic waste overboard into the Catalina Channel.”

Tuesday’s vote means the Board of Supervisors will send a letter to Michael Regan, the administrator of the Environmental Protection Agency, urging the federal government to analyze the extent of DDT damage off the coast and clean it up quickly. The county will also formally support a resolution from the state Assembly, which passed late last month and is currently awaiting a vote in the state Senate, that would also put pressure on the EPA.

“I think we need to support every effort possible,” Hahn said, “to restore our ocean life, our kelp forest and sea birds.”

DDT contamination off the Los Angeles coast, caused by the now-defunct Montrose Chemical Corp., has long been known to be a problem. Montrose reached a $140 million settlement with federal agencies in 2001, which included having the company pay for the Palos Verdes Reef Restoration Project that was completed last year.

But on April 26, scientists from UC San Diego’s Scripps Institution of Oceanography released a survey that detailed what potentially could be more than 27,000 barrels of dangerous chemicals. The barrels were discovered across 36,000 acres of seafloor, at depths of up to 3,000 feet. The barrels were about 12 miles offshore from the Palos Verdes Peninsula and eight miles offshore from Catalina Island.

But so far, officials do not know who is responsible for the recently discovered barrels — likely dumped decades ago — or what’s in them, though it could be DDT, a synthetic insecticide developed in the 1940s and banned in 1972 for its detrimental impacts on humans and wildlife.

Chris Lowe, who directs the Shark Lab at Cal State Long Beach, said at the Board of Supervisors meeting Tuesday the barrels likely pose greater risk to sea creatures.

“The concern with the deep site is that now we have barrels creating habitat,” Lowe told the supervisors, “which might actually attract animals. Many are capable of diving to those depths and can spread those chemicals. This site needs to be studied and assessed before a cleanup can begin.”

Supervisor Hilda Solis said it was important to bring those responsible for the barrels to justice, saying the dumping was egregious.

“We can’t continue to enable the bad actors from putting our communities at continued risk,” she said. “We have to strive for environmental justice such as the elimination of toxics and chemical from the ocean.”
