Alaska Underground Injection Control Class VI Primacy – Ends May 15

The Alaska Oil and Gas Conservation Commission recently informed the public that they intend to request the EPA for approval to directly regulate Class VI injection wells in areas where the state has jurisdiction. The UIC program regulates six different classes of injection wells based on their intended use. Class VI wells are used for the injection of carbon dioxide into deep rock formations for the purpose of long-term storage. There are currently no Class VI wells in Alaska. If the EPA approves the state’s request, Alaska would be the primary permitting and enforcement authority for any future proposed Class VI activities on land within the state’s jurisdiction. 

The EPA recognizes its unique relationship with Tribal governments as set forth in the United States Constitution, treaties, statutes, executive orders, and court decisions. The EPA will hold two webinars to share additional information. More information on joining these webinars is provided at the end of this letter to assist in your decision regarding whether to request consultation. 

If you would like additional information or would like to request government-to-government consultation, please have your staff contact Evan Osborne, the EPA staff lead for this action, at osborne.evan@epa.gov. We would appreciate a response to this government-to-government consultation offer no later than May 15, 2026.
