Air Plan Approval; AK: Updates to Materials Incorporated by Reference

The Environmental Protection Agency (EPA) is updating the materials 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. In this action, the EPA is also notifying the public of corrections to typographical errors, and minor formatting changes to the IBR tables. This update affects the SIP materials that are available for public inspection at the National Archives and Records Administration (NARA) and the EPA Regional Office.
