58-700 Definitions.
For the purposes of this article, the words set out shall have the following meanings:
Discharge means the addition of any waste, waste effluent, wastewater, pollutant, or any combination thereof to any surface water of the State.
Municipal separate storm sewer system (MS4) means all separate storm sewers that are owned or operated by the United States, a state, city, township, county, district, association, or other public body created by or pursuant to State law, having jurisdiction over disposal of sewage, industrial wastes, stormwater, or other wastes, including special districts under State law, such as a sewer district, flood control district, or drainage district, or similar entity, or a designated or approved management agency under Section 208 of the Clean Water Act that discharges to the waters of the State. This term includes systems similar to separate storm sewer systems in municipalities, such as systems at military bases, large hospital or prison complexes, and highways and thoroughfares. The term does not include separate storm sewers in very discrete areas, such as individual buildings.

Stormwater means stormwater runoff, snow melt runoff, surface runoff and drainage, and nonstormwater included under the conditions of this article.
Waters of the State means any of the following: groundwater; lakes, including the Great Lakes bordering the State; rivers; streams; all other water courses and bodies of water within the jurisdiction of the State, including wetlands as defined by Part 303 of the Act, wetlands protection, being SS324.30301 to 324.30323 of the Michigan Compiled Laws.
