803.03: STORM WATER ILLICIT DISCHARGE AND CONNECTIONS:
<br /> A. Purpose: The purpose of the ordinance is to promote,preserve and enhance the natural resources within
<br /> the City and protect them from adverse effects caused by non-storm water discharge by regulating
<br /> discharges that would have an adverse and potentially irreversible impact on water quality and
<br /> environmentally sensitive land. This ordinance will provide for the health,safety,and general welfare
<br /> of the citizens of the City of Roseville through the regulation of non-storm water discharges to the storm
<br /> drainage system to the maximum extent practicable as required by federal and state law.This ordinance
<br /> establishes methods for controlling the introduction of pollutants into the municipal separate storm
<br /> sewer system(MS4)in order to comply with requirements of the National Pollutant Discharge
<br /> Elimination System(NPDES)permit process. The objectives of this ordinance are:
<br /> 1. To regulate the contribution of pollutants to the municipal separate storm sewer system(MS4)by
<br /> storm water discharges by any person.
<br /> 2. To prohibit Illicit Connections and Discharges to the municipal separate storm sewer system.
<br /> 3. To establish legal authority to carry out all inspection,surveillance and monitoring procedures
<br /> necessary to ensure compliance with this ordinance.
<br /> B. Definitions: For the purposes of this ordinance,the following terms,phrases,words and their
<br /> derivatives shall have the meaning stated below.
<br /> 1. BEST MANAGEMENT PRACTICE(BMP):Erosion and sediment control and water quality
<br /> management practices that are the most effective and practicable means of controlling,preventing,
<br /> and minimizing the degradation of surface water,including construction-phasing,minimizing the
<br /> length of time soil areas are exposed,prohibitions,and other management practices published by
<br /> state or designated area-wide planning agencies.
<br /> a. Non-structural BMP: Practices that focus on preserving open space,protecting natural systems,
<br /> and incorporating existing landscape features such as wetlands and stream corridors to manage
<br /> storm water at its source.Other practices include clustering and concentrating development,
<br /> minimizing disturbed areas,and reducing the size of impervious areas.
<br /> b. Structural BMP: a physical device that is typically designed and constructed to trap or filter
<br /> pollutants from runoff,or reduce runoff velocities.
<br /> 2. COMMERCIAL: Activity conducted in connection with a business.
<br /> 3. DISCHARGE:Adding,introducing,releasing,leaking,spilling,casting,throwing,or emitting any
<br /> pollutant,or placing any pollutant in a location where it is likely to pollute waters of the state.
<br /> 4. EQUIPMENT: Implements used in an operation or activity. Examples include,but are not limited
<br /> to;lawn mowers,weed whips,shovels,wheelbarrows and construction equipment.
<br /> 5. EROSION:any process that wears away the surface of the land by the action of water,wind,ice,or
<br /> gravity. Erosion can be accelerated by the activities of man and nature.
<br /> 6. GROUNDWATER:Water contained below the surface of the earth in the saturated zone including,
<br /> without limitation,all waters whether under conned,unconfined,or perched conditions,in near
<br /> surface unconsolidated sediment or regolith,or in rock formations deeper underground.
<br /> 7. ILLEGAL/ILLICIT DISCHARGE:Any direct or indirect non-storm water discharge to the storm
<br /> drainage system,except as exempted in this chapter.
<br /> 8. ILLICIT CONNECTION:Either of the following:
<br /> a. Any drain or conveyance,whether on the surface or subsurface,which allows an illegal discharge
<br /> to enter the storm drain system(including any non-storm water discharge)including wastewater,
<br /> process wastewater,and wash water and any connections to the storm drain system from indoor
<br /> drains and sinks,regardless of whether said drain or connection had been previously allowed,
<br /> permitted,or approved by the City;or,
<br /> b. Any drain or conveyance connected from a residential,commercial or industrial land use to the
<br /> storm drain system which has not been documented in plans,maps,or equivalent records and
<br /> approved by the City.
<br /> 9. IMPERVIOUS SURFACE: A hard surface area which either prevents or retards the entry of water
