(a) Prohibition of Illicit Discharges. No Owner/Operator shall discharge, or cause to be discharged, any illicit discharge into the City's MS4. The commencement, conduct or continuance of any illicit discharge to the MS4 is prohibited; except as herein described:
(1) Waterline flushing; landscape irrigation; diverted stream flows; rising ground waters; uncontaminated ground water infiltration; uncontaminated pumped ground water; discharges from potable water sources; foundation drains; air conditioning condensate; irrigation water; springs; water from crawl space pumps; footing drains; lawn watering; individual residential car washing; flows from riparian habitats and wetlands; dechlorinated swimming pool discharges; street wash water; and discharges or flows from firefighting activities. These discharges are exempt until such time as they are determined by the City to be significant contributors of pollutants to the MS4.
(2) Discharges specified, in writing, by the City as being necessary to protect public health and safety.
(3) Discharges from off-lot discharging home sewage treatment systems permitted by the Greene County Combined Health District for the purpose of discharging treated sewage effluent in accordance with Ohio Administrative Code (OAC) 3701-29-02(6), until such time as the Ohio EPA issues an NPDES permitting mechanism for residential one-, two- or three-family dwellings. These discharges are exempt unless such discharges are deemed to be creating a public health nuisance by the Greene County Combined Health District.
(4) In compliance with the City's Stormwater Management Regulations, discharges from all off-lot discharging home sewage treatment systems must either be eliminated or have coverage under an appropriate NPDES permit, issued and approved by the Ohio EPA. When such permit coverage is available, discharges from off-lot discharging home sewage treatment systems will no longer be exempt from the requirements of this Chapter.
(b) Prohibition of Illegal Connections. The construction, use, maintenance, or continued existence of illegal connections to the MS4 is prohibited. This prohibition expressly includes, but is not limited to, illegal connections made in the past, regardless of whether the connection was permissible under law or practices applicable or prevailing at the time of connection. An Owner/Operator is considered to be in violation of this regulation if the Owner/Operator connects a line conveying illicit discharges to the MS4 or allows such connection to continue.
