Southern California Gas Co. on Oct. 8 released a memo to residents living near Aliso Canyon stating that a "minor release of natural gas" has occurred due to a malfunctioning valve on an oil tank storage in the area. The memo came after repairs had been made and the leak stopped.
The memo indicated that the incident had not resulted in any health or safety risks to Porter Ranch or the surrounding communities and elevated methane levels have not been detected at the eight pairs of fenceline monitors along the perimeter of the community, the Los Angeles Daily News reported Oct. 9.
The Sempra Energy subsidiary has also informed regulators and the appropriate agencies of the matter, the report said.
The utility asked the California Public Utilities Commission to greenlight a $480 million increase in its revenue requirement for 2019 relative to planned 2018 revenues, amounting to a 19.1% rise. SoCalGas said the nearly 20% increase in revenue in its 2019 general rate case will be put toward infrastructure upgrades in support of safety and reliability measures.
