Between December 2016 and April 2017, several crude oil and natural gas releases occurred from pipelines owned by Hilcorp Alaska, LLC’s offshore production and pipeline facilities in Alaska’s Upper Cook Inlet. 

A number of different federal and state agencies were involved in responding to those releases and questions arose regarding those various agencies’ authority, responsibilities and practices.

Following those releases, the U.S. Department of Transportation, Pipeline and Hazardous Material Safety Administration (PHMSA) initiated an intergovernmental effort with three specific goals: (1) to identify key stakeholders with an interest or responsibility for regulatory oversight of pipelines located within the waters of Upper Cook Inlet; (2) to inventory all current pipeline operators and assets within the waters of Upper Cook Inlet; and (3) to identify the federal and state agencies with regulatory authority over hazardous liquid and gas pipelines located within the waters of Upper Cook Inlet.
