Comparison: State vs. Federal
• Rules. Michigan is authorized by the U.S. Environmental Protection Agency (EPA) to issue state permits, general permits, federal facility permits, and pretreatment permits under the federal National Pollutant Discharge Elimination System (NPDES) permit program for wastewater discharges. Michigan issues three types of NPDES permits: individual permits, general permits, and permits-by-rule.
• Administration and enforcement. DEQ's Water Resources Division administers and enforces the NPDES permit requirements in Michigan.
Michigan issues NPDES general permits for stormwater discharges and for confined animal feeding operations (CAFOs). See the state sections STORMWATER-GENERAL and AG WASTE for more information on these types of NPDES discharge permits.
Michigan also issues state groundwater permits for wastewater discharges to the land or groundwater. See the state section
