The discharge of non-stormwater into the storm drain system is a violation of this chapter except as specified below.
(A) The discharge prohibition shall not apply to any discharge regulated under an NDPES Permit or Waiver issued to the discharger and administered by the State of California under the authority of the EPA, provided that the discharger is in full compliance with all requirements of the permit or waiver and other applicable laws or regulations.

(1) Discharges composed entirely of storm water;
(2) Air conditioning condensate;
(3) Irrigation water from agricultural sources;
(4) Discharges covered by a NPDES Permit, WDRs, or waivers issued by the Regional Board or State Board;
(5) Discharges from landscape irrigation, lawn/garden watering and other irrigation waters. These shall be minimized through public education and water conservation efforts, as prescribed under this Order Section XI.E. Residential Program;
(6) Passive foundation drains;
(7) Passive footing drains;
(8) Water from crawl space pumps;

However, appropriate BMPs to reduce the discharge of pollutants to the MEP must be implemented when they do not interfere with health and safety issues [see also Appendix K of the DAMP]);
(16) Waters not otherwise containing Wastes as defined in Cal. Water Code § 13050(d); and
