Municipal Separate Storm Sewer Systems (MS4)
On December 18, 2021, IDEM issued a Municipal Separate Storm Sewer General Permit (MS4GP). The MS4GP replaces 327 IAC 15-13 (Rule 13) which had previously been the Administrative Code that established the permitting requirements for all designated MS4s in Indiana. stormwater
MS4s are defined as a conveyance or system of conveyances owned by a state, city, town, or other public entity that owns or operates a system for collecting and conveying stormwater, and discharges to waters of the United States. Regulated conveyance systems include roads with drains, municipal streets, catch basins, curbs, gutters, storm drains, piping, channels, ditches, tunnels, and conduits. Combined sewer overflows and publicly owned treatment works are not included.
More information about the MS4 General Permit can be found on the Indiana Department of Environmental Management (IDEM) Website.

MS4 Stormwater Resolution & Ordinances for Muncie and Delaware County
Be on the lookout for signs of an illicit discharge. An illicit discharge is anything going into an MS4 conveyance (storm sewer, river, stream, ditch, swale) that is not composed ENTIRELY of storm water (see exceptions below).
What to look for (and report):
- Dumping of anything into a storm drain or waterway (or on a paved surface that can wash into a storm drain or waterway during rain events).
- Violations include: grass clippings, yard waste, pet waste, detergents, dirt/concrete wash water, paint, oil and other hazardous materials, trash.
- Anything unusual and unnatural in the waterways (e.g. smells, colors, “chalkiness”, oil sheen).
If you see any of these signs, please call our Report A Polluter Hotline: (765) 747-4896 or fill out our Report a Polluter Form. If possible, please take pictures and/or video, record the address and leave your name and phone number (not necessary, but helpful if there are questions).
Every person and organization in our MS4 (Muncie Sanitary District/City of Muncie, Delaware County, Town of Yorktown and Ivy Tech- Muncie) contributes to stormwater runoff, which is why funding must be mandated to complete Stormwater Management assessments, improvements, etc. to meet Federal and State mandates. This funding ensures mandatory MS4 compliance that is necessary to reduce pollution from entering our waterways, which results in improved water quality for the public, as well as the aquatic organisms that live in our waterways. For this reason, no one is exempt from paying stormwater fees, including churches, nonprofits, schools, and government buildings.
