Project Description

What's New

Additional Information about the Supplemental EIS Process:

 

In August 2021, the U.S. District Court for Alaska vacated the Record of Decision and Final EIS. The Bureau of Land Management is preparing a Supplemental Environmental Impact Statement (EIS) to address deficiencies identified by the court decision, and to ensure compliance with applicable law. This process relies on meaningful input from federal agencies, environmental organizations, Alaska Native organizations, numerous State of Alaska agencies and the affected communities along the North Slope. 
 

BLM Alaska is coordinating closely with eight cooperating agencies (US Fish and Wildlife Service, US Army Corps of Engineers, Inupiat Community of the Arctic Slope, North Slope Borough, State of Alaska, US Environmental Protection Agency, Native Village of Nuiqsut, and City of Nuiqsut) and external stakeholders to develop the Supplemental EIS.

The BLM held an informal scoping public comment period which ended on March 9, 2022, and the Notice of Availability for the Draft Supplemental EIS was published in the federal register on July 15, 2022. This began a 45-day public comment period which ended on August 29, 2022. 
 

The BLM published the Final Supplemental EIS on February 1, 2023.

The BLM has issued a new Record of Decision (ROD) for the Willow Master Development Plan Project which can be viewed on the Documents page.
