For the purposes of this chapter, the following shall mean:
BEST MANAGEMENT PRACTICES (BMPs)Devices or practices consistent with the guidelines set forth in the most current MDEQ Guidebook of BMPs for Michigan Watersheds, or equivalent practices and design criteria that accomplish the purposes of this chapter, as approved by the Department; that prevent pollutants from entering into stormwater flows; that direct the flow of stormwater; or that treat polluted water before it enters the stormwater system.
DISCHARGE PERMITA permit issued by the owner of the municipal separate storm sewer system (MS4) to a user for a discharge into the MS4.
ILLICIT CONNECTIONAny method or means for conveying an illicit discharge into the stormwater system.
ILLICIT DISCHARGEAny direct or indirect nonstormwater discharge (or seepage) to the stormwater system that is not composed entirely of stormwater or uncontaminated groundwater, except as exempted in this chapter. These are considered illicit because stormwater systems are not designed to accept, process or discharge such discharges.
MDEQMichigan Department of Environmental Quality.
MS4Municipal separate storm sewer system, as defined by federal and state laws.
NPDESNational Pollutant Discharge Elimination System, as addressed in 33 U.S.C. § 1342(b) and the Federal Clean Water Act, as amended.
NPDES STORMWATER DISCHARGE PERMITA permit issued by the U.S. Environmental Protection Agency (EPA) [or a state under authority delegated pursuant to 33 U.S.C. § 1342(b)] that authorizes the discharge of pollutants to waters of the United States, whether the permit is applicable on an individual, group, or general area-wide basis. For the purposes of this chapter, the subject NPDES permit is issued to the MS4 owner by the MDEQ.
PERFORMANCE STANDARDThe technical standard or set of standards to be met. Performance standards may be periodically revised by resolution of the Village Council in response to state and federal regulatory requirements, changed scientific knowledge, or similar changed conditions and/or enhanced knowledge.
PERSONAny individual, association, organization, partnership, firm, corporation or other entity recognized by law.
POLLUTANTAny substance which, alone or in combination with other substances, if discharged to waters of the state in sufficient quantities, causes or contributes to, or has the potential to cause or contribute to, a violation of a federal, state, or local water quality standard, a nuisance, or to render such waters harmful, detrimental or injurious to public health, safety or welfare, or to domestic, industrial, agricultural, recreational, or other legitimate beneficial uses or to any organism, aquatic life, plant or animal. Pollutants may include, but are not limited to: paints, varnishes and solvents; oil and other automotive fluids; nonhazardous liquid and solid wastes and yard wastes; refuse, rubbish, garbage, litter, or other discarded or abandoned objects, articles, and accumulations, so that same may cause or contribute to pollution; sediment; floatables; pesticides, herbicides, and fertilizers; hazardous substances and wastes; sewage, fecal coliform and pathogens; dissolved and particulate metals; animal wastes; residues that result from constructing a building or structure; and noxious or offensive matter of any kind.
STORMWATERRunoff from natural precipitation, including snowmelt, as well as other surface runoff and drainage that flow via natural or man-made drainageways.
STORMWATER DRAINAGE SYSTEM (STORMWATER SYSTEM)Any mode of conveyance that allows or permits the flow of stormwater to waters of the state, excluding combined sewer systems and sanitary sewer systems (separate stormwater systems are not intended to carry sanitary wastewater). The conveyance may be opened or enclosed, public or private, and may contain nonstormwater discharges. Specifically, the stormwater system includes all of the municipal storm drainage infrastructures and natural drainage designs that are intended to collect, control and provide a method of conveyance, discharge and perhaps treatment of stormwater. This may include roads with drainage systems, municipal streets, catch basins, inlets, curbs, gutters, ditches, and man-made swales, channels, wetlands, storm drains, outfalls, and treatment structures.
STORMWATER POLLUTION PREVENTION PLAN (SWPPP)A document which describes the best management practices (BMPs) and activities be implemented by a person or business to identify known or potential sources of pollution or contamination at a site and the actions to eliminate or reduce pollutant discharges to stormwater, stormwater drainageways, and/or receiving waters to the maximum extent practicable.
STORMWATER PROTECTION BOARD OF APPEALSA three-person board, appointed by the Village Council, to consider and decide appeals from decisions of the Stormwater Protection Administrator as well as such other matters as provided for in this chapter.
WASTEWATERAny water or other liquid, other than uncontaminated stormwater, discharged from a facility.
WATERS OF THE STATEThe Great Lakes and their connecting waters, all inland lakes, rivers, streams, impoundments, open drains, and other surface bodies of water within the confines of the state. It does not include drainageways and ponds used solely for wastewater conveyance, treatment, or control.
