Comparison: State vs. Federal
• Rules. South Carolina has incorporated by reference the National Emissions Standards for Hazardous Air Pollutants (NESHAPs), including the NESHAPs for source categories also known as maximum achievable control technology (MACT) standards. The incorporated MACT standards regulate emissions from major sources of hazardous air pollutants (HAPs) and nonmajor sources of HAPs known as area sources. See the national section HAZARDOUS AIR POLLUTANTS for more information on MACT standards.
In addition, there is a state program that establishes maximum allowable ambient concentrations for TAPs beyond the source's property line. The state list of TAPs is more extensive than the federal hazardous air pollutants (HAP) list.
• Administration and enforcement. South Carolina's DHEC administers and enforces the NESHAP and state toxic air pollutant regulations.
