Federal EPA regulations and state compliance
In addressing mercury pollution in Michigan, Federal EPA regulations play a pivotal role in setting the standards and frameworks that guide pollution control efforts. The U.S. Environmental Protection Agency (EPA) is the primary federal authority responsible for regulating mercury emissions under the Clean Air Act (CAA) and the Clean Water Act (CWA). Under the CAA, the EPA has established the Mercury and Air Toxics Standards (MATS), which specifically target mercury emissions from coal-fired power plants, the largest source of human-caused mercury emissions in the U.S. These regulations require facilities to install pollution control technologies to reduce mercury emissions by over 90%. Additionally, the EPA’s National Emissions Standards for Hazardous Air Pollutants (NESHAPs) further regulate mercury emissions from industrial sources, including incinerators and boilers. For water pollution, the EPA’s Water Quality Standards under the CWA mandate that states control mercury discharges into waterways to protect human health and aquatic ecosystems.
Michigan’s compliance with these federal regulations is overseen by the Michigan Department of Environment, Great Lakes, and Energy (EGLE), which acts as the state’s primary environmental regulatory agency. EGLE is responsible for implementing and enforcing federal EPA standards within the state, ensuring that industries and facilities adhere to mercury emission limits. For instance, EGLE issues permits to industrial facilities under the Michigan Air Pollution Control Rules, which incorporate EPA’s MATS requirements. Similarly, EGLE enforces the National Pollutant Discharge Elimination System (NPDES) permits for wastewater discharges, ensuring compliance with EPA’s mercury limits in water bodies. Michigan also participates in the Great Lakes Restoration Initiative, a federal program that includes efforts to reduce mercury contamination in the Great Lakes region, further aligning state actions with federal goals.
One critical aspect of state compliance is monitoring and reporting. EGLE conducts regular inspections of regulated facilities to verify compliance with EPA standards and collects data on mercury emissions and discharges.
