No person shall discharge or cause to be discharged into the storm drain system 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 storm water, including water runoff as defined in Chapter 13.07.

An illegal discharge is assumed to have occurred if prohibited material is placed, blown, washed, tracked or in any way allowed to accumulate in any part of the MS4 so that it can be conveyed by storm water. (Ord. 1543 § 2 (part), 2010)
