Comparison: State vs. Federal
• Rules. The federal regulations regarding NESHAPS, including source-specific NESHAPs known as maximum control technology (MACT) standards, are effective in Illinois and the federally listed hazardous air pollutants (HAPs) are included in the state-regulated list of TACs. Additional state-listed pollutants include those from the Great Waters and Coastal Waters Program in Section 112(m) of the Clean Air Act and pollutants listed by the Great Lakes Commission. In addition, Illinois is taking action on the state level to limit the release of mercury into the environment.
• Administration and enforcement. The Division of Air Pollution Control in IEPA's Bureau of Air administers and enforces the regulations governing HAPs and the state TAC regulations, including mercury emissions from the combustion of fossil fuel.
