MUNICIPALITIES- Illicit Discharge Detection & Elimination
The detection and elimination of pollutants being discharged into the MS4. Primarily, any discharge into the MS4 other than stormwater runoff including direct connections of waste water and effluent from residential or industrial/commercial sources. Municipalities must map all outfalls into surface water bodies, outfalls into adjacent MS4s and all infiltration practices such as dry-wells. Additionally, Municipalities must adopt a local law prohibiting illegal connection to or illegal dumping into the MS4. Lastly, Municipalities must regularly monitor outfalls for such discharges. Examples of prohibited practices include wastewater/grey water or rooftop runoff conveyances connected to the MS4 and disposal of chemicals and other waste products into ditches, storm sewers, catch basins, etc.

The CCE Stormwater Coordinator has 3 GPS units available on a lending basis to help Municipalities meet the outfall mapping requirement of the GP-02-02 Permit. Training is also available. 

Training will involve approximately an hour to an hour-and a-half of instruction on the basics of GPS and GIS technology, use of the GPS unit, and how to develop, prioritize & execute a mapping project. The remainder of the four-hour sessions will be spent in the field collecting data and getting familiar with the GPS Units, their capabilities and limitations.

Below are tools and links available for use by Municipal Governments and Stormwater Managers to help develop an Illicit Discharge Detection and Elimination Program:
