MS4/Stormwater

The MS4 department is involved in a variety of activities including:

  • Stormwater Permitting & Plan Review
  • Construction Inspection
  • Compliance with the Storm Water Quality Management Plan (SWQMP)

The MS4s are required to comply with a state-issued stormwater permit (INR040005). The MS4s are implementing a program to prevent stormwater pollution in urban runoff and improve the water quality of local water bodies.

The Stormwater Quality Management Plan (SWQMP) describes the MS4 program and the way in which the program is implemented. Annual Reporting of the MS4 program implementation measures and goals are required to be submitted to IDEM each year.
