Comparison: State vs. Federal
• Rules. Missouri does not regulate any hazardous air pollutants (HAPs) in addition to the federally listed pollutants, but the state has developed case-by-case permitting requirements for major sources of HAPs that are not included in a source category specifically covered by the federal standards. Missouri has adopted by reference the federal National Emissions Standards for Hazardous Air Pollutants (NESHAP) rules, including the source-specific NESHAPs, also known as maximum achievable control technology (MACT) standards. The Department of Natural Resources (DNR) periodically updates its adoption of the federal standards to include newly promulgated NESHAPs applicable to sources in the state. For further information, see the national section HAZARDOUS AIR POLLUTANTS.
• Administration and enforcement. The Air Pollution Control Program of DNR's Division of Environmental Quality administers and enforces the HAP rules in Missouri.
