(A) Unless specifically authorized in this Article, no person shall discharge or cause to be discharged any substance to the stormwater system that is not composed entirely of stormwater.
(B) Unless specifically authorized in this Article, no person shall use, store, spill, dump, discharge or dispose of materials that could reasonably be expected to cause or contribute to the addition of pollutants in stormwater.
(C) This section does not prohibit the following nonstormwater discharges from entering the city's MS4: water line flushing, landscape irrigation, diverted stream flows, uncontaminated pumped groundwater, discharges of potable water, foundation drains, air conditioning condensate, irrigation or lawn watering water, water from crawlspace pumps, footing drains, residential car washing, riparian and wetlands flows, dechlorinated swimming pool discharges, street wash water and discharges from firefighting activities.
(D) A number of discharges associated with potable and reclaimed water systems, subterranean dewatering, well development, aquifer testing, hydrostatic testing of specific pipelines, charitable car washes, building and street washing, and dechlorinated swimming pool water are regulated presently in Arizona by the AZPDES de minimus general permit, and hence the city will rely on the state regulatory agency to enforce compliance with these requirements.
