The Pipeline and Hazardous Materials Safety Administration (PHMSA), the lead federal regulatory agency for pipeline safety and integrity, is investigating a gas leak on Hilcorp's gas system in Cook Inlet, Alaska.
During the course of the investigation, PHMSA is consulting with several federal/state agencies in Alaska and Hilcorp to evaluate the risk to public safety, the environment and marine life.
As a result of these consultations on 3 March 2017, PHMSA issued a Notice of Proposed Safety Order to Hilcorp Alaska that requires the operator to permanently repair or shut down the affected pipeline by 1 May and make improvements to improve the integrity of the line. If PHMSA receives any new information regarding this leak, it will take appropriate additional action.
