Approval and Promulgation of Implementation Plans: Alaska

Environmental Protection Agency (EPA or we) approves the following revisions to the Alaska State Implementation Plan (SIP): a revision of the visible emission limit for coal burning boilers, during startup; shutdown; soot-blowing; grate cleaning; or other routine maintenance activities, that began operation before August 17, 1971, and submitted the required demonstration. Additionally, we are approving a revision to the definitions section that will add definitions of grate cleaning and soot-blowing. The Alaska Department of Environmental Conservation (ADEC) forwarded this submittal to EPA for inclusion in the Alaska SIP on November 1, 1999. These revisions were submitted for the purposes of complying with section 110 of the Clean Air Act.
