A. Prohibition Of Illegal Discharges: No person shall discharge or cause to be discharged into the municipal storm drainage system or watercourses any materials, including, but not limited to, pollutants or waters containing any pollutants, that cause or contribute to a violation of applicable water quality standards, other than stormwater. The commencement, conduct, or continuance of any illegal discharge to the storm drainage system is prohibited except as follows:
1. Water line and fire hydrant flushing or other potable water sources, storm sewer cleaning water, residual street wash water, landscape irrigation or lawn watering (except of wastewater irrigation), diverted stream flows, rising groundwater, groundwater infiltration to storm drains, uncontaminated pumped groundwater, foundation or footing drains (not including active groundwater dewatering systems), crawl space pumps, air conditioning condensation, springs, noncommercial washing of vehicles, natural riparian habitat or wetland flows, swimming pools (if dechlorinated - typically less than 1 ppm chlorine), firefighting activities, and any other water source not containing pollutants.
2. Discharges specified in writing by the authorized enforcement agency as being necessary to protect public health and safety.
3. Dye testing, but only with prior oral notification to the authorized enforcement agency prior to the time of the test.
4. Nonstormwater 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 other applicable laws and regulations, and provided that written approval has been granted for any discharge to the storm drainage system.
B. Prohibition Of Illicit Connections:
1. The construction, use, maintenance, or continued existence of illicit connections to the storm drainage system is prohibited.
2. 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.
3. A person is considered to be in violation of this chapter if the person connects a line conveying sewage to the MS4, or allows such a connection to continue.
4. Improper connections in violation of this chapter must be disconnected and redirected, if necessary, to an approved on site wastewater management system or the sanitary sewer system upon approval of the authorized enforcement agency.
5. Any drain or conveyance that has not been documented in plans, maps or equivalent, and which may be connected to the storm sewer 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 storm sewer system, sanitary sewer system or other discharge point be identified. Results of these investigations are to be documented and provided to the authorized enforcement agency. (Ord. 16-46, 9-19-2016)
