A state Senate committee approved a bill Tuesday that would prevent the reopening of the Aliso Canyon natural gas storage facility in Porter Ranch until an investigation is completed into the cause of a four-month methane leak from the facility.
The Senate Energy, Utilities and Communications Committee, however, amended the bill to authorize the governor to declare an emergency and temporarily allow gas injections at the facility to prevent interruptions in Southland energy supplies.
The bill will now move to the Senate Appropriations Committee before reaching the full Senate.
The Aliso Canyon storage facility has been largely out of use since the four-month leak spewed about 109,000 metric tons of methane into the air and led to the temporary relocation of about 7,000 residents. The leak began in October 2015 and was capped in February 2016.
State regulators are reviewing proposals that would allow Southern California Gas Co. to resume injecting gas into Aliso Canyon. The state Public Utilities Commission is also investigating whether use of the facility can be reduced or eliminated altogether.
Sen. Henry Stern, D-Agoura Hills, who sponsored Senate Bill 57, said the goal of the legislation “is to bring some comfort to the communities of the north valley without compromising the integrity of the grid.”
SoCalGas officials issued a statement saying the company is reviewing the legislation and amendments, but it remains convinced “that Aliso Canyon is safe and any legislation that prevents injections from resuming until the root cause analysis is completed is unnecessary.”
“According to a federal report, the leak occurred in the outer casing of the SS-25 well. Regardless of what the root cause analysis finds, the state’s comprehensive safety review has already demonstrated that the outer casings of every well approved for use are safe,” according to the Gas Co.
