Stormwater Matters -- Keep our waterways clean -- Only Rain down the drain!

The Clean Water Act (1972) authorizes the Environmental Protection Agency (EPA) to regulate point sources that discharge pollutants into waters of the United States through the National Pollutant Discharge Elimination System (NPDES) permit program. Objectives of the NPDES Stormwater Program are to reduce the discharge of stormwater pollutants to the maximum extent practicable, to protect water quality, and to satisfy the appropriate water quality requirements of the Clean Water Act. As a suburban community, Danvers is regulated by this permit program.

Stormwater is the water that runs off the land surface when it rains or snow melts.  It enters the Town’s storm drain system and flows directly to local lakes, streams, and wetlands. Stormwater runoff from undeveloped land is typically low since most rain or snow melt infiltrates into the ground or is lost to evaporation. Additional runoff from developed areas is created from impervious surfaces like streets, parking lots, and rooftops that prevent stormwater from naturally soaking into the ground.

Stormwater from developed areas typically contains a number of pollutants, such as oil and grease from roadways and parking lots, pesticides and fertilizers from lawns, sediment from construction sites, sand and dirt from roadway maintenance practices, and carelessly discarded trash such as cigarette butts, wrappers, and plastic bottles.  When these pollutants enter water bodies, they can contaminate drinking water supplies, hinder recreation activities, and harm aquatic and other wildlife habitats.

In addition to washing pollutants into our surface waters, improperly managed stormwater runoff can result in soil erosion and flooding.

In an on-going effort to minimize stormwater impacts within Danvers, the Town has developed a Stormwater Management Plan (SWMP) detailed in three sections below.  The first file details the SWMP sections 1-6, followed by Appendices A-E, finally Appendices F-G.  Last updated April 2021.

Municipal Separate Storm Sewer Systems (MS4) outfall screening

On April 5, 2019, the Town of Danvers received its Notice of Intent (NOI) approval from the Environmental Protection Agency and Massachusetts Department of Environmental Protection, to discharge stormwater from our MS4 in accordance with the terms and conditions of the MS4 General Permit. Under Section 3.3 BMP ID 3E-2 of the NOI, the Town is required to perform Dry Weather Outfall Screening and Sampling in accordance with the IDDE plan and permit conditions. All screening must be completed within three (3) years after the effective date of the permit.

During the next several months, the Danvers Engineering Division staff and our consultant Tighe & Bound will perform the outfall screenings at several locations.
