Colorado has incorporated the National Emissions Standards for Hazardous Air Pollutants (NESHAP) by reference, including the NESHAPs for source categories, also known as maximum achievable control technology (MACT) standards. Refer to the national section HAZARDOUS AIR POLLUTANTS for more information.
• Administration and enforcement. The CDPHE's Air Pollution Control Division administers and enforces the hazardous air pollutant rules in Colorado.
