Clean Air Act Attainment Extension for the Municipality of Anchorage Area Carbon Monoxide Nonattainment Area: Alaska

This action grants a one (1) year attainment date extension for the Municipality of Anchorage (MOA), Alaska carbon monoxide (CO) nonattainment area. The MOA area failed to attain the National Ambient Air Quality Standard (NAAQS) for CO by the December 31, 1995 deadline pursuant to the 1990 Clean Air Act Amendments (CAAA). CO attainment is based on eight (8) consecutive quarters (two years) of clean air quality data. There were two (2) exceedances of the CO NAAQS recorded in the nonattainment area in 1994, and no exceedances in 1995. Due to no exceedances in 1995 and the State's compliance with all requirements and commitments pertaining to the MOA area in the Alaska State Implementation Plan (SIP), an extension to meet the standards by December 31, 1996 is granted. This action is based on 1994 and 1995 monitored air quality data for the CO NAAQS.
