Notice of Proposed Changes on Air Quality Control in the Regulations of the Alaska Department of Environmental Conservation


The Alaska Department of Environmental Conservation proposes to change regulations on air quality and the Serious State Implementation Plan (SIP) for the Fairbanks North Star Borough (FNSB) nonattainment area. The proposed technical amendments are needed to demonstrate that the SIP will meet the annual five percent reduction in federal emission requirements identified in the Clean Air Act.


The Alaska Department of Environmental Conservation (ADEC) proposes to adopt a regulation change in Title 18, Chapter 50 the Alaska Administrative Code, dealing with air quality and the Fairbanks North Star Borough (FNSB) nonattainment area, including the following:
