(a) It shall be unlawful to discharge any domestic waste or industrial waste into the storm drain system, creeks, surface waters or San Francisco Bay. Unlawful discharges shall include, but not be limited to, discharges from toilets; sinks; industrial processes; cooling systems; boilers; fabric cleaning; equipment cleaning; vehicle cleaning; construction activities, including, but not limited to, painting, paving, concrete placement, saw cutting and grading; swimming pools; spas; and fountains, or substances added to the storm drain to control root growth, unless specifically permitted by a discharge permit or unless exempted pursuant to guidelines published by the superintendent.
(b) It shall be unlawful to cause hazardous materials, domestic waste or industrial waste to be deposited in such a manner or location as to constitute a threatened discharge into the storm drain system, creeks, surface waters or San Francisco Bay. Domestic or industrial wastes that are not contained in a pipe, tank or other container are considered to be threatened discharges unless the discharge has been controlled, the flow has been blocked and the material is actively being cleaned up.
(c) For all unauthorized or prohibited releases to the storm drain system including sanitary sewer overflows and threatened discharges to the storm drain system, the responsible person shall:
(1) Immediately take action to stop, contain, and clean up unauthorized or threatened discharges or otherwise stop the noncompliance, and correct the problem;
(2) Immediately notify the superintendent upon becoming aware of releases that result in discharge into the storm drain system, creeks, surface waters or San Francisco Bay.
(d) Interior floor drains shall not be connected to the storm drain system.
(e) Exterior drains located in the following areas shall not be connected to the storm drain system:
(1) Equipment or vehicle washing areas;
(2) Areas where equipment fluids are routinely changed;
(3) Areas where hazardous materials, chemicals or other uncontained materials that are easily transported by wind or water are stored and are not secondarily contained;
(4) Loading docks: See Section 16.09.175(k).
(f) Multi-family residential units and residential developments shall be prohibited from providing a designated vehicle washing area that would cause wash water to be deposited in such a manner or location as to constitute a threatened discharge into the storm drain system.
(g) Secondary containment shall be provided for any rooftop equipment, tanks or pipes containing other than potable water, cooling water, heating system hot water, steam, water condensate or equivalent substances, which the superintendent determines will otherwise cause a probable discharge to the storm drain system.
(h) Storm drain inlets shall be clearly marked with the words "No dumping - Flows to Bay," or equivalent.
