Comparison: State vs. Federal
• Rules. Wisconsin requires all sources of air contaminants to obtain an operating permit. Major sources must obtain a Title V permit. Wisconsin's operating permit program follows the federal program. The U.S. Environmental Protection Agency (EPA) granted full approval to Wisconsin's operating permit program, effective November 30, 2001.
