A new natural gas and petroleum leak occurred Saturday near Porter Ranch, not far from the shuttered well that spewed gas for four months, state officials reported.

The Governor’s Office of Emergency Services reported it received a complaint about a gas and petroleum leak at 8:25 a.m. from Southern California Gas Co. at its controversial Aliso Canyon Storage Facility.

The leak from a well, known as Standard Sesnon 1-21, was stopped at 10:25 a.m., according to an OES hazardous materials spill update, after it had spewed 30 gallons of oil spray and an unknown amount of natural gas.

“Earlier today we become aware that a third party company that operates at the Aliso Canyon site experienced a localized oil spill with gas venting at their petroleum well,” said SoCalGas in a community bulletin. “This well is not owned or operated by SoCalGas.”

The company said it immediately notified the California Governor’s Office of Emergency Services, as well as air, oil and gas regulatory agencies and local fire departments.

It was unclear Saturday what third-party company or subcontractor had been operating the leaking well.

One of 115 natural gas wells operated by SoCalGas sprung a leak in late October, releasing 100,000 tons of methane into the air in the largest gas leak in the nation. Thousands of residents complained of headaches, nosebleeds and other symptoms.

More than 7,000 homes and two schools were relocated at SoCal gas expense. An emergency declaration was issued. Numerous lawsuits have been filed.

After the new leak on Saturday, local conservationists repeated their call to permanently shut down the Aliso Canyon facility. The much depleted underground storage field, when full, supplies energy to power plants, institutions and millions of residents across Southern California.

“We are outraged!,” said Jennifer Milbauer, a spokeswoman for Save Porter Ranch, in a statement. “It’s more obvious than ever that Aliso Canyon is dangerous and needs to be completely shut down immediately, regardless of the operators in that field.

“These wells are old, decaying,” she added, “and this will continue to happen again and again, poisoning thousands in the nearby communities.”
