LOCAL STORMWATER PERMIT UPDATE

As of June 5, 2024, Monroe County's Stormwater Management Ordinance requires a local Stormwater Permit for land disturbing activities and a Logging Permit for commercial timber harvest activities. See the Stormwater Permitting webpage for more information. To apply for a permit, visit the OpenGov permit portal.

What is stormwater and why is it a concern?

Stormwater is the surface runoff resulting from rainstorms or melting snow.

As stormwater flows over impervious surfaces such as roads and parking lots, it often collects debris, chemicals, sediment and other pollutants before it flows to streams, lakes and other water bodies. In addition, excess runoff can contribute to more severe flooding events and cause erosion of valuable land.

Why is there a stormwater program?

The Clean Water Act and the Indiana MS4 General Permit require communities of a certain size to have a stormwater program that implements six Minimum Control Measures (MCMs):

  1. Public education and outreach
  2. Public participation and involvement
  3. Illicit discharge detection and elimination
  4. Construction site stormwater runoff control
  5. Post-construction stormwater runoff control
  6. Municipal operations pollution prevention and good housekeeping

The Monroe County Stormwater Program manages stormwater runoff within unincorporated Monroe County to minimize pollution and reduce flooding hazards in our waterways.

Important Construction Stormwater General Permit Update

As of 12/18/2021, IDEM no longer administers the construction stormwater permit program through Rule 5 (327 IAC 15-5).  Construction stormwater runoff is now regulated through the administrative Construction Stormwater General Permit (CSGP), a performance-based regulation designed to reduce pollutants associated with construction site runoff and/or land-disturbing activities.

You can find a copy of the new CSGP here

For more information about the transition to CSGP and the new performance standards click here.  For a detailed description of the CSGP and the new performance standards click here.  For a detailed description of the CSGP construction process within Monroe County, visit our Stormwater Permitting page.
