Comparison: State vs. Federal
• Rules. Mississippi has no additional state-listed hazardous air pollutants (HAPs). The state has adopted and incorporated by reference the federal NESHAP standards, including the NESHAPs for source categories, also known as maximum achievable control technology (MACT) standards. Major sources of HAPs that are not included in a source category specifically covered by the federal standards must make MACT determinations on a case-by-case basis. Refer to the national section HAZARDOUS AIR POLLUTANTS for more information.
• Administration and enforcement. DEQ's Air Division is responsible for administering and enforcing the hazardous air pollutant rules in Mississippi.
