(A)   Prohibition of illicit discharges. No person shall discharge or cause to be discharged into the city's MS4 any materials other than stormwater.
   (B)   Exceptions. The following discharges are exempt from the prohibitions of this chapter:
      (1)   Water line flushing or flushing of 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 (including active groundwater dewatering systems), air conditioning condensation, springs, non-commercial washing of vehicles, natural riparian habitat or wet-land flows, swimming pools (if de-chlorinated to less than 1.0 mg/l chlorine), fire fighting activities, and any other water source not containing pollutants;
      (2)   Discharges specified in writing by the city as being necessary to protect public health and safety;
      (3)   Dye testing, but this requires a verbal notification to the city prior to the time of the test;
      (4)   Any non-stormwater discharge that is permitted under an NPDES permit, waiver, or waste discharge order issued to the discharger and administered under the authority of IDEM, 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)   Immediate suspension of access in emergency situations. The city may, without prior notice, suspend MS4 discharge access to a person when such suspension is necessary to stop an actual or threatened illicit discharge which presents or may present imminent and substantial danger to the environment, or to the health or welfare of persons or to the MS4 or Waters of the United States.
   (D)   Suspension order due to the detection of illicit discharge. The city will issue a written suspension order to any person that is found to be responsible for an active or potential illicit discharge. If the violator fails to comply with such a suspension order in a reasonable period of time, the city may take such steps as deemed necessary to prevent or minimize damage to the MS4 or Waters of the United States, or to minimize danger to persons. Any person responsible for an illicit discharge or connection may have their MS4 access terminated. The violator may petition the Board for a reconsideration and hearing.
   (E)   Reinstatement offense. A person commits an offense if the person reinstates MS4 access to premises terminated pursuant to this section, without the prior approval of the city.
