Summary

The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) submittal from the Alaska Department of Environmental Conservation (Alaska DEC) demonstrating that the SIP meets certain interstate transport requirements of the Clean Air Act (CAA) for the National Ambient Air Quality Standards (NAAQS) promulgated in 2010 for nitrogen dioxide (NO<INF>2</INF>) and sulfur dioxide (SO<INF>2</INF>). The EPA proposes to determine that Alaska's SIP contains adequate provisions to ensure that air emissions in Alaska do not significantly contribute to nonattainment or interfere with the maintenance of the 2010 NO<INF>2</INF> and SO<INF>2</INF> NAAQS in any other state.

The agency’s own summary, as published.
