Almost three years after the largest gas leak in U.S. history, the state attorney general’s office has reached a tentative settlement of litigation brought against the Southern California Gas Co. over the blowout in Aliso Canyon that sickened thousands with nosebleeds and nausea and caused massive evacuations in the Porter Ranch community.

Attorney General Xavier Becerra stated late Tuesday in a prepared statement his office would announce the agreement and presumably fill in the details at a news conference Wednesday morning alongside state, city and county leaders at the Ronald Reagan State Building in downtown Los Angeles.

Participating in the press announcement will be: Los Angeles Mayor Eric Garretti, Los Angeles City Councilman Mitch Englander, L.A. City Attorney Mike Feurer and L.A. County Supervisors Kathryn Barger and Hilda Solis.

The apparent settlement comes after a succession of litigation, some still pending, and others resolved over the leak — which spewed nearly 100,000 metric tons into the air.

While gas was still spewing from the Aliso Canyon well in early 2016, California’s attorney general — then Kamala Harris — Attorney General Kamala Harris alleged in a lawsuit that SoCalGas violated state health and safety laws by not promptly controlling the release of natural gas, which had by then been leaking methane at its storage facility in the hills above Porter Ranch since Oct. 23. That leak, Harris alleged, was also not quickly reported to authorities.

Reaction to the settlement on Tuesday was swift from residents who have disagreed with the state, city and county’s response to the leak and also to the Gas Co. restarting its use of the gas fields to store more methane.

“If history repeats itself then no good will come from this,” said Andrew Krowne, activist and developer of an app to help residents detect further gas leaks. “The oil and gas companies will pay their way out of any accountability for their actions.”

“Thus far, all of the settlements that have already occurred have done so at the detriment of the public,” added Krowne, who spoke late Tuesday night. Krowne and his family were evacuated from their Chattsworth home after the leak and stayed in a hotel for five months.

Craig Galanti, a Porter Ranch resident and activist, also did not expect his family and the residents who experienced illness in the community will benefit.

“I’m really disappointed that they put corporate profit before public health,” he said during a phone interview Tuesday night. “I hope that reversed in tomorrow’s decision. A settlement should never be just a slap on the wrist”

Krowne said one possible positive outcome would be an award of $40 million to the state to then be used to pay for a thorough health study. But he did not think that would happen.

About 9,000 residents have sued SoCalGas and are currently in the discovery phase of a class-action suit. Early testimony centered on whether the methane gas leaked substances into the air in more than safe amounts, such as benzene and formaldehyde.

The Gas Co. has assured residents that levels of air toxics, which can cause cancer, are well within the acceptable levels set by state and federal health and environmental agencies.
