It is unlawful for any person to discharge any substance other than naturally occurring stormwater runoff into the City’s storm drainage system. 


Sec. 50-52.  Unlawful discharges into storm drainage system.

(a)   It shall be unlawful for any person to discharge or cause to be discharged or spilled into the city's storm drainage system any substance, including but not limited to dirt, mud, landscape materials, hazardous substances such as but not limited to oil products or gasoline, paint, concrete, or any type of cleaning waste or residue. Only naturally occurring stormwater runoff can be discharged into the city's storm drainage system, with the following exceptions: return flows from irrigation, water from building foundation drainage, runoff from noncommercial car washing, dechlorinated water from swimming pools or water mains, water used for firefighting, discharges of water from ditches and canals as necessary to protect public drinking water supplies, and other waters determined by the city to be noncontaminated and acceptable for return to the storm drainage system and stream system. Nothing contained herein shall be construed to relieve any person discharging water into the storm drainage system from any liability for damage caused by the volume or quality of water thus discharged. For purposes of this section the term "storm drainage system" shall be defined as provided in section 50-51 and the term "stormwater runoff" shall be defined to include any flow of water resulting from rain or other forms of natural precipitation.
(b)   The discharge prohibition shall not apply to any non-stormwater discharge permitted under the Colorado Discharge Permit System, waiver, or waste discharge order issued to the discharger and administered under the authority of the Federal Environmental Protection Agency, provided that the city does not determine that the discharge is a significant source of contamination.
