of the City Code of Rosemount, Minnesota, are incorporated herein, and, the following shall mean:
BEST MANAGEMENT PRACTICES (BMPs): Practices to prevent or reduce the discharge of pollutants directly or indirectly to stormwater, groundwater, receiving surface waters, or stormwater conveyance systems. BMPs include schedules of activities, prohibitions, other management practices, also include treatment practices/requirements, operating procedures, and practices to control site runoff, spillage or leaks, sludge or water disposal, or drainage from raw materials storage. On construction sites, BMPs include The most effective and practicable means of erosion prevention and sediment control, and water quality management practices that are the most effective and practicable means to control, prevent, and minimize degradation of surface water, including avoidance of impacts, construction phasing, minimizing the length of time soil areas are exposed, prohibitions, pollution prevention through good housekeeping, and other management practices published by state or designated area wide planning agencies.
CITY: The City of Rosemount.
CLEAN WATER ACT: The federal water pollution control act (33 USC section 1251 et seq.), and any subsequent amendments thereto.
CONSTRUCTION ACTIVITY: A disturbance to the land that results in a change in the topography, existing soil cover (both vegetative and nonvegetative), or the existing soil topography that may result in accelerated stormwater runoff, leading to soil erosion and movement of sediment into surface waters or drainage systems. Examples of construction activity may include clearing, grading, filling and excavating.
CONSTRUCTION STORMWATER OR CSW: Stormwater associated with construction activity.
HAZARDOUS MATERIALS: Any material, including any substance, waste, or combination thereof, that because of its quantity, concentration, or physical, chemical, or infectious characteristics may cause, or significantly contribute to, a substantial present or potential hazard to human health, safety, property, or the environment when improperly treated, stored, transported, disposed of, or otherwise managed.
ILLEGAL DISCHARGE OR ILLICIT DISCHARGE: Any direct or indirect nonstormwater discharge to the storm drain system, except as exempted in this chapter.
ILLICIT CONNECTIONS: Any drain or conveyance, whether on the surface or subsurface, that allows an illegal discharge to enter the storm drain system including, but not limited to, any conveyances that allow any non-stormwater discharge including sewage, process wastewater, and wash water to enter the storm drain system and any connections to the storm drain system from indoor drains and sinks, regardless of whether said drain or connection had been previously allowed, permitted, or approved by the city or any other government agencies with permitting authority or, any drain or conveyance connected from a commercial or industrial land use to the storm drain system that has not been documented in plans, maps, or equivalent records and approved by the city or other government agencies with permitting authority.
INDUSTRIAL ACTIVITY: Activities subject to NPDES industrial permits as defined in 40 CFR, section 122.26(b)(14).
MPCA: The Minnesota Pollution Control Agency.
MUNICIPAL SEPARATE STORM SEWER SYSTEM OR MS4: A stormwater system or portion thereof subject to an NPDES MS4 Permit.
NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES): The program for issuing, modifying, revoking, reissuing, terminating, monitoring, and enforcing permits under the United States Clean Water Act, as amended. Applicable federal regulations include 33 U.S.C. 1251 et seq. Section 1342 and 40 CFR parts 122, 123, 124 and 450. The NPDES Programs regulating discharges to Waters of the United States for construction stormwater, industrial stormwater, and municipal stormwater are administered by the Minnesota Pollution Control Agency (MPCA) in the State of Minnesota.
NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM STORMWATER DISCHARGE PERMIT OR NPDES PERMIT: A permit issued by MPCA that authorizes the discharge of stormwater to Waters of the United States, whether the permit is applicable on an individual, group, or general areawide basis. This chapter is primarily concerned with NPDES Permits for Industrial Activity, Construction Stormwater, and Municipal Separate Storm Sewer Systems.
NONSTORMWATER DISCHARGE: Any discharge to the storm drain system that is not composed entirely of stormwater.
PERSON: Any individual, organization, firm, corporation, partnership, franchisee, association or governmental entity.
POLLUTANT: Anything that causes or contributes to pollution. 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; eroded soil or sediment; refuse, rubbish, garbage, litter, or other discarded or abandoned objects, pesticides, herbicides, and fertilizers; hazardous substances and wastes and residues that result from constructing a building or structure; and noxious or offensive matter of any kind, that, because of its quantity, concentration, or physical, chemical, or infectious characteristics may cause, or significantly contribute to, a substantial present or potential hazard to human health, safety, property or the environment, or that may degrade, impair or pollute ground or surface waters.
PREMISES: Any building, lot, parcel of land, or portion of land whether improved or unimproved including adjacent sidewalks and parking strips.
SECONDARY CONTAINMENT OR SECONDARY SPILL CONTAINMENT: Any system, device, or control measure used to capture spills or leaks of hazardous liquids and prevent them from migrating from their storage area in order to prevent pollution to soils and waters.
STORM DRAIN SYSTEM OR STORMWATER SYSTEM: Publicly owned facilities by which stormwater is collected and/or conveyed, including, but not limited to, any roads with drainage systems, municipal streets, gutters, curbs, inlets, piped storm drains, pumping facilities, retention and detention basins, natural and humanmade or altered drainage channels, reservoirs, and other drainage structures.
STORMWATER: Surface flows of water generated from precipitation events. Stormwater includes precipitation runoff, stormwater runoff, snowmelt runoff, and any other surface runoff and drainage.
STORMWATER POLLUTION PREVENTION PLAN: A document that describes the best management practices and activities to be implemented by a person or business to identify sources of pollution or contamination at a site and the actions to eliminate or reduce pollutant discharges to stormwater, stormwater conveyance systems, and/or receiving waters to the maximum extent practicable.
WASTEWATER: Any water or other liquid, other than uncontaminated stormwater, discharged from a facility. (Ord. XVI.61, 5-19-2009, eff. 5-19-2009; amd. Ord. 2023-05, 10-3-2023)
