Mansfield’s Stormwater Management Program
The EPA nationally regulates the discharge of stormwater runoff that is transported through municipal drainage systems into local waterbodies through the National Pollutant Discharge Elimination System (NPDES) stormwater program. The NPDES stormwater program includes the following components, called Minimum Control Measures (MCMs):
- Public education and outreach
- Public participation
- Illicit discharge detection and elimination
- Management of construction site runoff
- Management of post-construction site runoff for new development and redevelopment
- Good housekeeping and pollution prevention in municipal operations
Summary of the Six Minimum Control Measures for Small MS4
The Town of Mansfield must implement specific policies and procedures for each MCM to help reduce pollution in local waterbodies. The program also includes requirements to address specific pollutants found in stormwater where waters are not meeting water quality goals or designated uses (e.g., fishable, swimmable) under the Clean Water Act. In Mansfield, this means reducing the levels of total phosphorus and solids in stormwater runoff.

Notice of Intent for discharging manholes
To comply with program requirements, the Town of Mansfield developed a Notice of Intent (NOI) to request authorization to discharge stormwater. The NOI was submitted to EPA and MassDEP on October 1, 2018. It includes information about the Town’s status of compliance with the NPDES stormwater program, a summary of waterbodies within Town that receive stormwater discharges, and best management practices (BMPs) the Town will implement to address the six MCMs. A Stormwater Management Plan (SWMP) will also be finalized by June 30, 2019, which summarizes the Town’s stormwater program and the NOI in greater detail.

Stormwater Management on a Residential Property
The Town of Mansfield has been committed to managing stormwater through the incorporation and implementation of the local Stormwater Management Bylaw in 2006. The Mansfield Stormwater Management Bylaw, Chapter 185 of Bylaw, along with the Stormwater Management Standards, established in 1996 within the Wetland Protection Act (310 CMR 10.00) apply to large-scale commercial, industrial or multiple residential projects. Work on a single-family residential lot is mostly exempt from these regulations. A single residential lot might not be the most obvious source of pollution problems, but behind a suburban landscape, there may be activities that can threaten our water quality within our single source aquifer.
Pollutants commonly present on residential lots include pesticides fertilizers used in landscaping. Other pollutants may include sediment from erosion-prone areas, yard waste such as leaves and grass clippings, pet waste and oil and gas from driveway surfaces. Even runoff from rooftops can contain pollutants known to occur in rainfall. These have the potential to be transported in stormwater to surface water bodies, posing risks to the environment and human health. While the contribution from an individual yard may seem small, the cumulative effects of stormwater runoff coming from hundreds or thousands of homes within a watershed can be significant. Reducing the amount of stormwater that leaves your property as runoff helps to prevent pollutants from reaching our streams, lakes, ponds and other wetland resource areas.
