Tonka Bay's SWPPP Plan

A Municipal Separate Storm Sewer System (MS4) is a conveyance, or system of conveyances (i.e. municipal streets, catch basins, curbs, gutters, ditches, channels, etc.) that is designed to collect storm water and is owned and operated by a public entity.  It is regulated under the National Pollutant Discharge Elimination System (NPDES) MS4 permit.  Tonka Bay is required to minimize pollutants that enter their systems through a Storm Water Pollution Prevention Plan (SWPPP), which includes six minimum control measures (MCM) that address the following areas:
1.                  Public education and outreach

2.                  Public information and involvement

3.                  Illicit discharge detection and elimination

4.                  Construction site storm water runoff control

5.                  Post-construction storm water management

6.                  Pollution prevention and good housekeeping
In order to comply, the adjacent poster board provides information on the work and implementation of the city's MS4 program.

Tonka Bay will implement their best management practices in these six areas and can do so in a timeframe that makes sense for the city.
Citizens who wish to provide input on the adequacy of the SWPPP, or if you have additional questions or concern, can email Superintendent of Public Works, Todd Schallberg, at tschallberg@cityoftonkabay.net or call 952-474-2947.
