The City Engineer will require Best Management Practices for any activity, operation, or facility which may cause or contribute to pollution or contamination of storm water, the MS4, or waters of the State. The owner or operator of a commercial or industrial establishment shall provide, at his/her own expense, reasonable protection from accidental discharge of prohibited materials or other wastes into the MS4 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 MS4. Compliance with all terms and conditions of a valid NPDES permit authorizing the discharge of storm water associated with this chapter, 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 (SWPPP) as necessary for compliance with requirements of the NPDES permit. (Ord. 2009- 12. Passed 3-31-09.)
