(A) Prohibition of illegal discharges. No person shall discharge or cause to be discharged into the municipal storm drain 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 storm water. The commencement, conduct or continuance of any illegal discharge to the storm drain system is prohibited. The following is a partial list, provided for informational purposes only, of common substances which are illicit discharges when allowed to enter a public drainage control system: solid waste, human and animal waste, antifreeze, oil, gasoline, grease and all
other automotive and petroleum products, flammable or explosive materials, metals in excess of naturally occurring amounts whether in liquid or solid form, chemicals not normally found in uncontaminated water, solvents and degreasers, painting products, drain cleaners, commercial and household cleaning materials, pesticides, herbicides, fertilizers, acids, alkalis, ink, steam-cleaning waste, laundry waste, soap, detergent, ammonia, chlorine, swimming pool or hot tub water, domestic or sanitary sewage, animal carcasses, food and food waste, yard waste, dirt, sand and gravel, and commercial car wash discharge water.
(B) Permissible discharges. The following discharges are exempt from discharge prohibitions established by this chapter: water line flushing or other potable water sources, landscape irrigation or lawn watering, diverted stream flows, rising ground water, ground water infiltration to storm drains, uncontaminated pumped ground water, foundation or footing drains (not including active groundwater de-watering systems), crawl space pumps, air conditioning condensation, springs, non-commercial washing of vehicles, natural riparian habitat or wetland flows, swimming pools (if de-chlorinated, typically less than one PPM chlorine), fire fighting activities, and any other water source not containing pollutants. Dye testing is an allowable discharge, but requires a verbal notification to the authorized enforcement agency prior to the time of the test. 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 Arkansas Department of Environmental Quality 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 drain system.
(C) Prohibition of illicit connections. The construction, use, maintenance or continued existence of illicit connections to the storm drain 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 to the MS4, or allows such a connection to continue.
