Current Regulations: Anchorage had a winter (Nov. - Feb.) oxygenated gasoline (min. 2.7 wt%) ethanol only program. On July 30, 2003, the Alaska DEC announced the suspension of this program because Anchorage has complied with the carbon monoxide NAAQS for the last six years.

On April 1, 2002, the Alaska Dept. of Environmental Conservation submitted a plan to EPA for implementation of EPA's highway diesel ultra low sulfur regulations (ULSD). "Urban" Alaska would follow the same schedule as the rest of the U.S. In May 2003, ADEC recommended a community-choice approach for rural Alaska's transition to ULSD; before June 2010, a rural community could bring in ULSD on its own timeframe, as dictated by local priorities, concerns, and logistics; however, model year 2007 and newer highway diesel vehicles must use ULSD. EPA promulgated an effective date of June 1, 2010 for refiners and importers for the ultra-low sulfur, cetane and aromatics requirements for highway, nonroad, locomotive and marine diesel fuel in rural Alaska (71 FR 32450; 6/6/06).
