§ 20-205. Discharge prohibitions.

No person shall discharge or cause to be discharged into the county separate storm sewer 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 drain system is prohibited, except as follows:

(1)

The following discharges are exempt from discharge prohibitions established by this article: water line flushing or other potable water sources, landscape irrigation or lawn watering, 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, de-chlorinated swimming pools (less than one 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 and approved by the county engineer or designee.

(3)

The prohibition shall not apply to any non-stormwater discharge permitted under an NPDES permit, waiver, or wastewater discharge order issued to the discharger and administered under the authority of the Federal 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 drain system and approved by the county engineer or designee.
