Approval and Promulgation of Implementation Plans; State of Alaska; Revised Format of 40 CFR Part 52 for Materials Incorporated by Reference

The Environmental Protection Agency (EPA) is revising the format for materials submitted by the State of Alaska that are incorporated by reference (IBR) into the Alaska State Implementation Plan (SIP). The regulations affected by this format change have all been previously submitted by Alaska and approved by the EPA. This format revision will primarily affect the "Identification of plan" section, as well as the format of the SIP materials that will be available for public inspection at the National Archives and Records Administration (NARA), the Air and Radiation Docket and Information Center located at the EPA Headquarters in Washington, DC, and the EPA Regional Office. The EPA is also adding a table in the "Identification of plan" section which summarizes the approval actions that the EPA has taken on the non-regulatory and quasi-regulatory portions of the Alaska SIP.
