No person shall discharge, or cause to be discharged, an illicit discharge into the MS4. The commencement, conduct or continuance of any illicit discharge to the MS 4 is prohibited except as described as follows:
(a) Water line 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 Authorized Enforcement Agency to be significant contributors of pollutants to the MS4.
(b) Discharges specified in writing by the Authorized Enforcement Agency as being necessary to protect public health and safety.
(c) Discharges from household sewage treatment systems existing prior to January 1, 2007 and permitted by the Warren County Board of Health for the purpose of discharging treated sewage effluent in accordance with Ohio Administrative Code 3701-29, or other applicable Warren County Board of Health regulations, until such time as the Ohio Environmental Protection Agency issues an NPDES permitting mechanism for household sewage treatment systems existing prior to January 1, 2007. These discharges are exempt unless such discharges are deemed to be creating a public health nuisance by the Warren County Board of Health. Discharges from new or replacement household sewage treatment systems installed after January 1, 2007 are not exempt from the requirements of this regulation.
(d) The prohibition shall not apply to any non-storm water discharge permitted under an NPDES permit, waiver, or waste discharge order issued to the discharger and administered under the authority of the Environmental Protection Agency, provided that the discharger is in full compliance with all requirements of the permit, waiver, or order and other applicable laws and regulations, and provided that written approval has been granted for any discharge to the MS4.
