A. Any person causing or allowing discharge to a storm water drainage system, surface waters or groundwater shall limit pollutants in the discharge by implementing source control best management practices (BMPs). “Applicable” source control BMPs in Volume IV of the current Stormwater Management Manual for Western Washington shall be used to reduce or eliminate the release of pollution citywide.

B. “Recommended” source control BMPs in Volume IV of the current Stormwater Management Manual for Western Washington shall be used to reduce or eliminate the release of pollution citywide if “applicable” source control BMPs do not prevent pollution. “Recommended” source control BMPs are identified by land use and specific business types. The City may require additional “recommended” source control BMPs and/or treatment BMPs or facilities if such BMPs or facilities are deemed necessary by the Director and/or his or her designee to eliminate an ongoing release of pollution. (Ord. 3031 § 2, 2021; Ord. 2859 § 2 (part), 2016: Ord. 2473 § 2 (part), 2009).
