City of Attleboro Stormwater Management

Stormwater runoff is the result of water from a rain/snow event flowing across impervious services. Impervious services include but are not limited to streets, parking lots, or buildings. As stormwater flows over these surfaces, it collects pollutants in the form of oils, trash, and chemicals. Much of the City’s municipal drainage system ultimately drains into various waterways. These pollutants can have negative impacts on the quality of our natural resources and our ecosystem. Through the NPDES program, the City is working diligently to provide treatment for any stormwater runoff within our jurisdictional limits. This includes constructing new stormwater management systems and maintaining existing infrastructure to provide proper treatment and mitigation for stormwater.

The Environmental Protection Agency (EPA) requires many communities to apply for MS4 permit coverage under the Phase II National Pollutant Discharge Elimination System (NPDES) Program of the federal Clean Waters Act. The MS4 permit program is comprised of six minimum control measures that are designed to result in significant reductions of pollutants discharging into waterways.

The six program elements include:

1. Public Education and Outreach

2. Public Participation/Involvement

3. Illicit Discharge Detection and Elimination

4. Construction Site Runoff Control

5. Post Construction Runoff Control

6. Pollution Prevention/Good Housekeeping
