Air Pollution Control Program
Section 9 Hazardous Air Pollutant Modeling Requirements
Hazardous air pollutants (HAPs), also known as air toxics, are air pollutants associated with elevated cancer levels and other adverse health effects. New emission units, or modifications to existing emission units, that have the potential to emit HAPs may be required to obtain a construction permit before commencing construction. New emission units may also be subject to the federal standards found in 40 CFR Part 63, known as National Emission Standards for Hazardous Air Pollutants for sources that fall within the following categories: Maximum Achievable Control Technology and Generally Available Control Technology standards. The following document provides a summary of the permit review requirements for HAPs.
