ANCHORAGE, Alaska (AP) — Federal regulators have ordered Hilcorp Alaska to replace a 7-mile undersea pipeline after a helicopter pilot spotted a natural gas leak bubbling to the surface last week.
The Pipeline and Hazardous Materials Safety Administration on Tuesday said the company must also submit and the agency must approve a restart plan before the line in Cook Inlet can resume operations.
The Anchorage Daily News reports that the leak is the fifth one for the subsea line since 2014. Hilcorp has until late May to provide a plan to replace the aging pipeline.
The company then has one year to replace the pipeline.
