Illicit Discharge Reporting

What is an Illicit Discharge?

An illicit discharge is any discharge to an MS4 that is not composed entirely of stormwater or uncontaminated groundwater. The only things entering an MS4 should be uncontaminated groundwater or stormwater that is free of pollutants, debris, oils, residues, etc.

Why are Illicit Discharges a Problem?

Illicit discharges are a problem because they can pollute waterways without any treatment. Water from the storm sewer system typically is discharged directly from storm pipes to waterways so any pollutants being carried in the stormwater will also enter waterways.

Identifying an Illicit Discharge

An illicit discharge may have occurred if you notice that a storm sewer is discharging water, or if water or other liquids (other than stormwater) are entering the MS4. If the storm sewer is conveying water when there has been no rain, there is a chance it could be a sign of an illicit discharge.

How Can You Help?

You may notice stormwater inlets near your property, along roadways, or near businesses. You can monitor these stormwater inlets and take note if it seems like anything has been dumped into the storm sewer system.

If you do notice any potential pollutants entering the stormwater sewer system, please contact the Township: Call 610-539-8020 during the hours 8:00 AM - 4:30 PM.
