Summary
In the City of Eden Prairie, no one may dump pollutants into the storm sewer system or use an illicit connection to send non-stormwater into it. City Code § 5.75 implements the City's federal NPDES permit by banning illegal dumping and illicit discharges into the Municipal Separate Storm Sewer System.
All water entering the stormwater system will be protected from illegal disposal/dumping and illicit discharges and connections.A.Illegal Disposal/Dumping. No person shall throw, drain or otherwise discharge, cause or allow others under its control to throw, drain or otherwise discharge into a Stormwater System any pollutants or waters containing any pollutants other than stormwater.B.Illicit Discharges and Connections.1.No person shall cause any illicit discharge to enter a Stormwater System.2.No person shall use any illicit connection to intentionally convey non-stormwater to a Stormwater System.
Full Breakdown
Section 5.75, Subdivision 3 of the Eden Prairie City Code protects the City's Municipal Separate Storm Sewer System (MS4) from two categories of misconduct. Illegal disposal or dumping bars anyone from throwing, draining, or otherwise discharging pollutants, or allowing others under their control to do so, into a Stormwater System. Illicit discharges and connections separately bar causing any illicit discharge to enter a Stormwater System, using an illicit connection to intentionally convey non-stormwater into one, and constructing, using, maintaining, or simply letting an illicit connection continue to exist, even one built before this section existed.
Subdivision 4 exempts specific ordinary flows from the ban, including firefighting water, landscape irrigation, residential car washing, air conditioning condensation, and dechlorinated swimming pool water discharged after the chlorine has evaporated. Subdivision 5's good housekeeping rules add that pool water over 1,000 gallons must sit at least seven days without added chlorine before being discharged, and any facility under an MPCA General Stormwater Permit for industrial or construction activity must submit its Proof of Coverage to the City before discharging. The City may inspect any Stormwater System to check compliance, and if access is refused where probable cause exists, the City can seek a search warrant (Subd. 7). Subdivision 9 declares any violation a public nuisance that the City may abate at the violator's expense.
Violations & Fines
Discharging pollutants, causing an illicit discharge, or maintaining an illicit connection to Eden Prairie's storm sewer system violates Section 5.75, Subd. 3, and is unlawful under Subdivision 8, which lets the City suspend Stormwater System access without prior notice when a discharge presents imminent danger. Subdivision 9 additionally declares any violation a public nuisance the City may abate at the violator's expense, and Subdivision 10 lets the City assess unpaid abatement costs, including administrative costs, against the property.
