Comparison: State vs. Federal
• Rules. Many mobile source regulatory programs are implemented at the federal level and are having a positive effect on air quality in Wisconsin. In addition, the state has implemented vehicle inspections and maintenance (I/M), stage II vapor recovery, and clean fuel fleet programs, as well as requirements addressing emission control device tampering, diesel particulate matter emissions, and visible emissions. Several of these programs are implemented in selected counties in which such programs are necessary to attain and maintain the National Ambient Air Quality Standards.
• Administration and enforcement. DNR's Air Management Program, in conjunction with the DOT, administers and enforces the mobile source programs in Wisconsin.
