No person shall cause or allow the discharge, emission, disposal, pouring or pumping directly or indirectly into the town storm drain system, watercourses, any storm water conveyance, the waters of the state or upon the land in manner and amount that the substance is likely to reach a storm water conveyance or the waters of the state, any liquid, solid, gas or other substance, other than storm water. The commencement, conduct or continuance of any illegal discharge to the storm drain system is prohibited except as described as follows:
(A) Discharges from the following activities will not be considered a source of pollutants to the storm drain system and to waters of the United States when properly managed to ensure that no potential pollutants are present, and therefore they shall not be considered illegal discharges unless determined to cause a violation of the provisions of this chapter; water line flushing; uncontaminated pumped ground water; discharges from potable water sources; landscape irrigation; irrigation water; lawn watering; diverted stream flows; rising ground water; uncontaminated ground water infiltration (as defined at 40 C.F.R. § 35.2005(20)) to the storm drain system; uncontaminated foundation and footing drains; uncontaminated water from crawl space pumps; air conditioning condensation; uncontaminated roof drains; springs; individual residential car washing; flows from riparian habitats and wetlands; dechlorinated swimming pool discharges; street wash waters; and other non-storm water discharges for which a valid NPDES discharge permit has been approved and issued by the state, and provided that any of the discharges to the municipal separate storm sewer system shall be authorized by the town.
(B) 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 by the state under the authority of the Federal 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 notification of the permitted discharge has been filed with the Storm Water Administrator, in a form acceptable to the Storm Water Administrator, for any discharge to the storm drain system.
(C) With written concurrence of the State Department of Environment and Natural Resources, the Storm Water Administrator may exempt in writing other non-storm water discharges, which are not a source of pollutants to the storm drain system or waters of the United States.
