Comparison: State vs. Federal
• Rules. Sources of hazardous air pollutants (HAPs) in Connecticut must comply with the federal NESHAP standards, including source-specific NESHAPs, also known as maximum achievable control technology (MACT) standards. In addition, Connecticut has implemented a regulation for the control of state HAPs, in addition to the federal HAPs, which establishes emissions limits for over 850 substances on the basis of health standards. The regulation is designed to address localized impacts of state HAP emissions by limiting the concentration at the source's property line. All sources must comply with the requirements, not just selected source categories, as is the case with MACT standards.
• Administration and enforcement. DEP's Bureau of Air Management implements and enforces the HAP rules and mercury management programs in Connecticut.
