The Stormwater Program for Municipal Separate Storm Sewer System (MS4) operators is intended to reduce the pollutant loading to water resources from storm sewer systems to the “maximum extent practicable.”
The document can be found at the link below or is available as a hard copy at Chanhassen City Hall. You may also request that a copy be sent to you either electronically or via U.S. mail by contacting Terry Jeffery. Chanhassen’s MS4 Permit was approved May 8th, 2014. The City will be updating the existing SWPPP per new permit and our application.
