NOTICE OF PROPOSED CHANGES ON CARBON STORAGE AND UNDERGROUND INJECTION CONTROL CLASS VI WELLS IN THE REGULATIONS OF THE ALASKA OIL AND GAS CONSERVATION COMMISSION
Summary of proposed changes: The Alaska Oil and Gas Conservation Commission (AOGCC) proposes to adopt regulation changes in Title 20 Chapter 25 of the Alaska Administrative Code, dealing with carbon storage as it relates to Class VI wells and establishing a new Class VI Underground Injection Control program for Alaska, including the following:
(1) 20 AAC 25.402, title “Enhanced recovery operations,” is proposed to be updated with conforming amendments relating to “Class II” wells.
(2) 20 AAC 25.435, titled “Identification of underground sources of drinking water,” is proposed to add language stating that new aquifer exemptions will not be issued for a Class VI well.
(3) 20 AAC 25.442, titled “Expansion to the areal extent of existing Class II aquifer exemption for a Class VI well”, is proposed to add requirements to allow an owner or operator to request an expansion to an existing aquifer exemption for the purpose of a Class VI well.
(4) 20 AAC 25.444, titled “Transitioning from a Class II well to a Class VI well”, is proposed to add requirements for an operator of a Class II well to obtain a Class VI carbon storage permit when the primary purpose is the long-term storage of carbon or there is an increased risk to underground sources of drinking water compared to Class II operations.
(6) 20 AAC 25.505, titled “Scope of regulations”, is proposed to be changed to include the new sections 20 AAC 25.1000 – 20 AAC 25.1900.
(7) 20 AAC 25.535, titled “Enforcement”, is proposed to be amended to add provisions to implement AS 41.06.105-AS 41.06.210 in sections (a), (e), and (h).
(8) 20 AAC 25.556, titled “Orders”, is proposed to be amended to add a new subsection (e). This addition would establish an order for a preapplication fee for storage facility permitting without an expiration date.
(9) 20 AAC 25.990, titled “definitions” is proposed to amend and add new definitions.
(10) The AOGCC also proposes adding a new Title 20, Chapter 25, Article 9, titled “Carbon Storage (20 AAC 25.1000 – 20 AAC 25.1900)” to implement AS 41.06.105 – AS 41.06.210, the Carbon Capture, Utilization, and Storage Act as it relates to Class VI wells and to implement regulations required for the AOGCC to apply for Class VI primary enforcement authority (Primacy) from the United States Environmental Protection Agency (EPA) as a new well Class within the Underground Injection Control (UIC) program. Section 1422 of the Safe Drinking Water Act (SDWA) requires Primacy applicants to implement a program that is as stringent as EPA’s requirements for UIC programs and to enforce UIC program requirements that protects underground sources of drinking water from endangerment. Class VI wells are used for injection of carbon dioxide for long term underground storage. Regulations proposed to be added include sections:
