Aliso Canyon Natural Gas Leak

U.S. EPA Involvement in the Response to the
Natural Gas Leak at the SoCalGas Aliso Canyon Facility

California state and local agencies are on the forefront of the response to the natural gas leak at Southern California Gas Company's Aliso Canyon facility. They include the California Office of Emergency Services (Cal OES), the California Division of Oil, Gas and Geothermal Resources (DOGGR), the South Coast Air Quality Management District, the County of Los Angeles Fire and Public Health Departments, the City of Los Angeles, the California Public Utilities Commission (CPUC), the California Air Resources Board (CARB), the California Energy Commission (CEC), the Division of Occupational Safety and Health (Cal/OSHA), and the Office of Environmental Health Hazard Assessment (OEHHA).

The U.S. Environmental Protection Agency is participating in daily operational calls with these local and state regulators and Southern California Gas Company to stay abreast of developments in controlling the gas release and assisting local residents. On Dec. 18, EPA sent a federal Clean Air Act information request letter to Southern California Gas Company for additional data and documents related to the facility and its operation. EPA is currently reviewing the information submitted and expects to receive additional information from the company in coming days. After completing its review of this information and in consultation with the state and local regulators already active on the scene, EPA will determine the appropriate next steps.
