(A) The county requires the use of BMPs for any activity, operation, or facility, which may cause or contribute to pollution or contamination of stormwater, the storm drain system, or the waters of the state. This requirement includes facilities and operations covered under a NPDES permit (Industrial, Construction, and Municipal Storm Sewer System) as well as non-permitted facilities. Guidance for selecting and implementing BMPs may be found on the MPCA's website under the Storm Water Program.
(B) 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 county MS4 or watercourses through the use of structural and non-structural BMPs. Further, any person responsible for a property or premises, which is, or may be, the source of an illegal 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 county's MS4. Compliance with all of the 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 division.
