12.08.100 Exceptions to discharge.
No person shall commence, conduct, or continue any illegal discharge to the storm drain system except as follows. Discharges from the following will not be considered a source of pollutants to the storm drain system and to waters of the United States when properly managed to ensure that no potential pollutants are present, and therefore they shall not be considered illegal discharges unless determined to cause a violation of the provisions of the Porter-Cologne Act, Clean Water Act, or this chapter:
A. Uncontaminated groundwater, air conditioning condensation, uncontaminated roof, foundation, footing, or French drains (not including active groundwater dewatering systems), flows from riparian habitats and wetlands, residential car washing and fire fighting flows.
B. Non-storm water discharge permitted under an NPDES permit, waiver, low-threat discharge permit or waste discharge order issued to the discharger and administered by the state of California 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 by the city for any discharge to the storm drain system.
C. With written concurrence of the Central Coast Regional Water Quality Control Board, the city may exempt in writing other non-storm water discharges, which are not a source of pollutants to the storm drain system nor waters of the United States. (Ord. 1543 § 2 (part), 2010)
