Abstract
On June 12, 1997, the Environmental Protection Agency (EPA) published an action of proposed rulemaking discussing its decision to approve a revision to the Michigan State Implementation Plan (SIP) to grant an exemption for the Muskegon County ozone nonattainment area from the applicable Oxides of Nitrogen (NO<INF>X</INF>) transportation conformity requirements. See Federal Register (62 FR 32058). No comments were received by the EPA during the 30-day comment period. This rule finalizes EPA's decision to approve the exemption for Muskegon County, moderate ozone nonattainment area, from the transportation conformity requirements for NO<INF>X</INF>. The Michigan SIP revision request is based on the urban airshed modeling (UAM) conducted for the attainment demonstration for the Lake Michigan Ozone Study (LMOS) modeling domain.
