Full Breakdown

Lakewood Municipal Code § 13.14.040 makes it unlawful to discharge or place polluting materials, including petroleum products, solvents, fertilizers and pesticides, so they enter the municipal storm sewer. Under § 13.14.100, the city defines a 'significant' site triggering Stormwater Discharge Permit requirements as one disturbing one acre or more, or a smaller site that is part of a larger common plan of development that will ultimately disturb an acre or more. The Environmental Manager enforces the chapter as a peace officer under § 13.14.090.

Discharging polluting material into the storm sewer or developing a qualifying site without a Stormwater Discharge Permit violates §§ 13.14.040 and 13.14.100, exposing the violator to a cease-and-desist order, a municipal court summons, or nuisance abatement, with each day a separate violation.
