Michigan (Part 60) NSPS and (Part 61) NESHAP Delegations
Michigan has delegation of all existing and future Part 60 New Source Performance Standards (NSPS) and Part 61 National Emission Standards for Hazardous Air Pollutants (NESHAPs) standards. Michigan has primary implementation and enforcement authority for the delegated standards.
Section 111 of the federal Clean Air Act directs EPA to establish pollution control requirements for certain industrial activities which emit significant "criteria air pollutants." These requirements are known as new source performance standards (NSPS) and regulate pollutants such as particulate matter, sulfur dioxide, carbon monoxide, nitrogen oxides, volatile organic compounds, acid mist, total reduced sulfur and fluorides. NSPS are detailed in Chapter 40 of the Code of Federal Regulations, Part 60 (40 CFR Part 60), and are intended primarily to establish minimum nationwide requirements for new facilities.
Section 112 of the pre-1990 federal Clean Air Act directed EPA to establish standards to reduce emissions of hazardous air pollutants (HAPs). These pollutants include asbestos, benzene, beryllium, inorganic arsenic, mercury, radionuclides, and vinyl chloride. NESHAPs are detailed in 40 CFR Part 61 and establish minimum nationwide requirements for existing and new facilities.
