STATE REGULATORY AGENCY
In Michigan, the counterpart to the U.S. Environmental Protection Agency (EPA) is the Michigan Department of Environmental Quality (DEQ). DEQ is responsible for protecting Michigan's land, water, and air from pollution. Michigan has been delegated authority by EPA to administer and enforce regulatory programs for air emissions, surface wastewater effluent and stormwater discharges, groundwater discharges, and solid and hazardous waste management. Various state regulatory requirements for water quality protection and waste management are more stringent than corresponding federal requirements. Michigan has its own federally approved occupational safety and health plan.
AIR QUALITY RULES
Michigan's air quality program is shaped by its state implementation plan (SIP), which sets forth basic strategies for implementation, maintenance, and enforcement of the National Ambient Air Quality Standards (NAAQS). As mandated by the federal Clean Air Act (CAA), each state must adopt and submit a SIP to EPA for approval. Michigan's SIP was officially submitted to EPA in February 1972 and is frequently amended to comply with the 1990 CAA amendments. The SIP focuses on permitting, nonattainment areas, hazardous air pollutants (HAPs), emissions standards, and numerous other air-related requirements.
Michigan's air quality rules are implemented and enforced by DEQ's Air Quality Division.
