CONSTRUCTION ACTIVITY: 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 include clearing, grading, filling, excavating, building construction and landscaping.
HAZARDOUS MATERIALS: Any materials which because of 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.
ILLICIT CONNECTION: Any drain or conveyance, whether on the surface or subsurface, which allows an illegal discharge to enter the storm drain system including any nonstormwater discharge including sewage, process wastewater, and wash water 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 an authorized enforcement agency.
ILLICIT DISCHARGE: Any direct or indirect nonstormwater discharge to the storm sewer system, except as exempted in section 7-16-3, "Stormwater And Urban Runoff Control", of this chapter.
MPCA: The Minnesota pollution control agency.
NPDES: The national pollutant discharge elimination system; the program for issuing, modifying, revoking, reissuing, terminating, monitoring, and enforcing permits under the clean water act (sections 301, 318, 402, and 405) and United States code of federal regulations title 33, sections 1317, 1328, 1342, and 1345 authorizing the discharge of pollutants to water of the United States.
POLLUTANT: Any substance which, when discharged has potential to or does:
A. Interfere with state designated water uses;
B. Obstruct or cause damage to surface waters;
C. Change water color, odor or usability as a drinking water source through causes not attributable to natural processes affecting surface water or subsurface processes affecting groundwater;
D. Add an unnatural surface film on the water;
E. Adversely change other chemical, biological, thermal or physical conditions in any surface water;
F. Degrade the quality of groundwater; or
G. Harm human life, aquatic life or terrestrial plant and wildlife.
Pollutants may include dredged soil, solid waste, garbage, wastewater, chemical waste, biological materials including yard waste and animal waste, rock, sand, dust, industrial waste, sediment, nutrients, toxic substances, pesticide, herbicide, fertilizer, trace metal, automotive fluid, petroleum based substances, oxygen demanding material, fecal coliform and pathogens, wastes and residues that result from constructing a building or structure and noxious or offensive matter of any kind.
SEWAGE: Any water carried domestic waste, exclusive of footing and roof drainage of any residence, industry, agriculture or commercial establishment whether treated or untreated and includes the liquid wastes produced by bathing, laundry and culinary operations; and from toilets and floor drains.
SEWER SYSTEM: Pipelines or conduits, pumping stations and force mains and all other constructions, devices, appliances, or appurtenances used for conducting sewage or industrial waste or other wastes to a point of ultimate disposal.
STORM SEWER SYSTEM: A conveyance or system of conveyances that is owned and operated by the city or other entity and designed or used for collecting or conveying stormwater.
STORMWATER: As defined under Minnesota rule 7077.0105, subpart 41(b) means "precipitation runoff, stormwater runoff, snowmelt runoff, and any other surface runoff and drainage".
STORMWATER POLLUTION PREVENTION PLAN (SWPPP): A stormwater and erosion and sediment control plan containing the requirements of this chapter, that when implemented will decrease soil erosion on a parcel of land and off site nonpoint pollution. It involves both temporary and permanent controls.
WASTEWATER: Liquid wastes, usually water that has been used, as for washing, flushing, or in a manufacturing process, and so contains waste products, collected in a sewer system and conveyed to a treatment plant for processing. (Ord. 884, 10-3-2011)
