The City will adopt requirements identifying Best Management Practices (BMPs) for any activity, operation or facility which may cause or contribute to pollution or contamination of stormwater, the stormdrain system or waters of the U.S. The owner or operator of a commercial or industrial establishment shall provide, at their own expense, reasonable protection from accidental discharge of prohibited materials or other wastes into the municipal stormdrain system or watercourses through the use of these structural and non-structural BMPs. Further, any person responsible for a property or premise, which is, or may be, the source of an illicit discharge, may be required to implement, at said person’s expense, additional structural and non-structural BMPs to prevent the further discharge of pollutants to the municipal separate storm sewer system. Compliance with all terms and conditions of a valid NPDES permit authorizing the discharge of Stormwater associated with industrial activity, to the extent practicable, shall be deemed compliance with the provisions of this section. These BMPs shall be part of a Stormwater Pollution Prevention Plan (SWPP) as necessary for compliance with requirements of the NPDES permit. Such SWPP shall be adopted by the City of Wood Village by the City Manager.
