Determination of Attainment of Ozone Standard by Grand Rapids and Muskegon, Michigan; Determination Regarding Applicability of Certain Reasonable Further Progress and Attainment Demonstration Requirements

On June 2, 1995 the USEPA published a direct final and proposed rulemaking determining that the Grand Rapids (Kent and Ottawa Counties) and Muskegon (Muskegon County), Michigan moderate ozone nonattainment areas were attaining the ozone National Ambient Air Quality Standard (NAAQS). Based on this determination, the USEPA also determined that certain reasonable further progress and attainment demonstration requirements, along with certain other related requirements, of part D of Title 1 of the Clean Air Act (Act) are not applicable to the areas so long as the areas continue to attain the ozone NAAQS. The 30-day comment period concluded on July 3, 1995. During this comment period, the USEPA received two comment letters in response to the June 2, 1995 rulemaking. This final rule summarizes all comments and USEPA's responses, and finalizes the USEPA's determination that these areas have attained the ozone standard and that certain reasonable further progress and attainment demonstration requirements as well as other related requirements of part D of the Act are not applicable to these areas as long as these areas continue to attain the ozone NAAQS.
