(A) Prohibition of illegal discharges.
(1) No person shall discharge or cause to be discharged into the stormwater drainage system or waters of the United States any materials, pollutants, or waters containing any pollutants that cause or contribute to a violation of applicable water quality standards.
(2) The commencement, conduct, or continuance of any illegal discharge to the stormwater drainage system is prohibited except as described as follows:
(a) The following discharges are exempt from discharge prohibitions established by this chapter: water line flushing, fire hydrant flushing, discharges from potable water sources, landscape irrigation, lawn watering, rising groundwater, groundwater infiltration, uncontaminated pumped groundwater, diverted stream flows, natural riparian habitat and wetland flows, springs, storm sewer cleaning water, street wash water from streets where spills or leaks of pollutants or toxic or hazardous materials has not occurred (unless the pollutants or toxic or hazardous materials have been removed), foundation drains, footing drains, crawl space pumps, air conditioning condensation, non-commercial vehicle washing, routine external building washing that does not use detergents, dechlorinated swimming pool discharges (discharges must contain less than one part per million chlorine), fire fighting activities, and any other water source not containing pollutants or toxic or hazardous materials.
(b) Discharges specified in writing by the authorized enforcement agency as being necessary to protect public health and safety.
(c) Dye testing is an allowable discharge, but requires a verbal notification to the authorized enforcement agency prior to the time of the test.
(d) The prohibition shall not apply to any non-stormwater discharge permitted under an NPDES permit, waiver, or waste discharge order issued to the discharger and administered under the authority of the United States Environmental Protection Agency, provided that the discharger is in full compliance with all requirements of the permit, waiver, or order and all other applicable laws and regulations, and provided that written approval has been granted by the authorized enforcement agency for the discharge to the stormwater drainage system.
(B) Prohibition of illicit connections. The construction, use, maintenance, or continued existence of illicit connections to the stormwater drainage system is prohibited. This prohibition expressly includes, without limitation, illicit connections made in the past, regardless of whether the connection was permissible under law or practices applicable or prevailing at the time of connection. A person is considered to be in violation of this chapter if the person connects a line conveying sewage or any other non-stormwater discharge to the MS4, or allows such a connection to continue. Improper connections in violation of this chapter must be disconnected and redirected, if necessary, to an approved onsite wastewater management system or the sanitary sewer system upon approval of the authorized enforcement agency. Any drain or conveyance that has not been documented in plans, maps or equivalent, and which may be connected to the stormwater drainage system, shall be located by the owner or occupant of that property upon receipt of written notice of violation from the authorized enforcement agency requiring that such locating be completed. Such notice will specify a reasonable time period within which the location of the drain or conveyance is to be determined, that the drain or conveyance be identified as storm sewer, sanitary sewer or other, and that the outfall location or point of connection to the stormwater drainage system, sanitary sewer system or other discharge point be identified. Results of those investigations are to be documented and provided to the authorized enforcement agency.
