|Description||Effective April 30, 2021, the U.S. Environmental Protection Agency designated a small area in the northwest corner of Washington State as a nonattainment area for the 2010 sulfur dioxide National Ambient Air Quality Standard. “Nonattainment” means not meeting or complying with the standard. The designated area is a 4.5-square-mile portion of an industrial area, Cherry Point, in Whatcom County. The area encompasses the site of an aluminum smelter, Intalco Aluminum LLC, and adjacent areas. Ecology, in consultation with NWCAA, developed this attainment plan to permanently reduce and control the amount of sulfur dioxide in the nonattainment area.|
