Storm Water Pollution Prevention Program

More About the Program

Inver Grove Heights is fortunate to have an abundance of surface water resources. The city is dotted with many wetlands and lakes, and the Mississippi River flows along the city’s eastern border. 

The city has adopted a number of policies and ordinances over the years to protect these water resources so that they may be enjoyed by both current and future residents of Inver Grove Heights. These policies and ordinances are intended to prevent property damage due to storm water flooding and to protect the quality of the surface water resources that receive storm water runoff. 

As part of its mandatory efforts to protect the quality of surface water resources, the city applied for, and received, a National Pollutant Discharge Elimination System (NPDES) storm water permit in 2003. This federal permit is administrated by the Minnesota Pollution Control Agency (MPCA). 

Permit Requirements

The permit requires that the city, as the owner of a Municipal Separate Storm Sewer System (MS4), develop and implement a Storm Water Pollution Prevention Plan (SWPPP) to reduce the discharge of pollutants from its storm sewer system to the maximum extent practicable. The city’s SWPPP must cover six minimum control measures:

  • Public education and outreach
  • Public participation / involvement Illicit discharge, detection and elimination
  • Construction site runoff control
  • Post-construction site runoff control
  • Pollution prevention / good housekeeping

Annual report

The city must identify Best Management Practices (BMPs) and measurable goals associated with each minimum control measure. The Inver Grove Heights Annual Report for Municipal Storm Sewer Systems provides a summary of the city’s status of complying with permit conditions and identifies the best management practices being used towards achieving the city’s identified measurable goals.
