For the purposes of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
   BEST MANAGEMENT PRACTICES (BMPs). Schedules of activities, prohibitions of practices, general good housekeeping practices, pollution prevention and educational practices, maintenance procedures, and other management practices to prevent or reduce the discharge of pollutants directly or indirectly to stormwater, receiving waters, or stormwater conveyance systems. BMPs also include treatment practices, operating procedures, and practices to control site runoff, spillage or leaks, sludge or water disposal, or drainage from raw materials storage.
   BMP PLAN (STORMWATER POLLUTION PREVENTION PLAN or SWPPP). A document which 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.
   CLEAN WATER ACT. The federal Water Pollution Control Act (33 U.S.C. §§ 1251 et seq.), and any subsequent amendments thereto and regulations promulgated thereunder.
      (1)   A construction activity is part of a larger COMMON PLAN OF DEVELOPMENT if it is completed in one (1) or more of the following ways: in separate stages; in separate phases; in combination with other construction activities. It is identified by the documentation that identifies the scope of the project including such things as the following: plats; blueprints; marketing plans; contracts; building permits; public notice or hearing; zoning requests. It can include one operator or many operators.
      (2)   Example: A subdivision is being built. You are grading three-fourths (3/4) of an acre, another company is clearing four (4) different acres, and a contractor is excavating another one-half (1/2) acre. In this case, the total area that would be disturbed is five and one-fourth (5-1/4) acres, so each operator would fall under the requirements associated with disturbing one (1) or more acres.
   CONSTRUCTION ACTIVITY. Activities subject to NPDES construction permits. These include construction projects resulting in land disturbance of one (1) acre or more or part of a common plan of development. Such activities include but are not limited to clearing and grubbing, grading, excavating, and demolition.
   HAZARDOUS MATERIALS. Any material, including any substance, waste, or combination thereof, which 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. Any direct or indirect non-stormwater discharge to the storm drain system, except as exempted in § 53.06.
   ILLICIT CONNECTIONS. Any drain or conveyance, whether on the surface or subsurface, which allows an illegal discharge to enter the municipal separate storm sewer system including but not limited to any conveyances which allow any non-stormwater discharge including sewage, process wastewater, and wash water to enter the municipal separate storm sewer system and any connections to the municipal separate storm sewer system from indoor drains and sinks, regardless of whether said drain or connection had been previously allowed, permitted, or approved by the city.
   INDUSTRIAL ACTIVITY. Activities subject to NPDES industrial permits as defined in 40 CFR, §122.26 (b)(14).
   MUNICIPAL SEPARATE STORM SEWER SYSTEM (MS4). 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 human-made or altered drainage channels, reservoirs, and other drainage structures.
   NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) STORMWATER DISCHARGE PERMIT. A permit issued by the EPA (or by 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.
   NON-STORMWATER DISCHARGE. Any discharge to the municipal separate storm sewer system that is not composed entirely of stormwater.
   POLLUTANT. Anything which causes or contributes to pollution. POLLUTANTS may include, but are not limited to: paints, varnishes, and solvents; oil and other automotive fluids; non-hazardous liquid and solid wastes and yard wastes; refuse, rubbish, garbage, litter, or other discarded or abandoned objects, ordnances, and accumulations, so that same may cause or contribute to pollution; pesticides, herbicides, and fertilizers; hazardous substances and wastes; sewage, fecal coil form and pathogens; dissolved and particulate metals; animal wastes; wastes and residues that result from constructing a building or structure; and noxious or offensive matter of any kind.
   WASTEWATER. Any water or other liquid, other than uncontaminated stormwater, discharged from a facility.
