Stormwater Management Plan

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.

Information on all Massachusetts communities regulated by the Phase II Stormwater Program can be found on the EPA Site.

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 years after the effective date of the permit.

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