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.

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 <br />
