|Hazardous air pollutants are defined by the Federal Clean Air Act as pollutants that cause or may cause cancer or other serious health effects, such as reproductive effects or birth defects, or adverse environmental and ecological effects. MDEQ implements hazardous air pollutant regulations that include Maximum Achievable Control Technology (MACT) standards and other National Emission Standards for Hazardous Air Pollutants (NESHAP) and also provides technical assistance for the requirements of regulations to anyone who may be interested. A list of Hazardous Air Pollutants can be viewed here.|

- Processing regulation promulgations and amendments and identification of regulated facilities within the state
- Providing technical assistance for the requirements of regulations to anyone who may be interested

Ambient air monitoring for hazardous air pollutants has been done at various locations (link below) throughout the state off and on from May of 2001 through December of 2013. The specific monitoring efforts have included the characterization of air quality for concentrations of common hazardous air pollutant emissions in areas of more likely incidence of elevated levels. These efforts have included the EPA’s Urban Air Toxics Monitoring Program, an evaluation of ambient air quality impacts following Hurricane Katrina, participation in EPA’s Air Toxics in Schools Study, and a study to evaluate ambient air concentrations in Columbus, MS.
The data produced from these efforts, available through the link below, provided a favorable picture of air quality for the pollutants and areas monitored, indicating no problem or troublesome conditions that warranted corrective actions.
