Phase II Stormwater Management Program

Stormwater discharges in the City of Amesbury are regulated by the U.S. Environmental Protection Agency (EPA) National Pollutant Discharge Elimination System (NPDES) Phase II Stormwater Permit Program. Under this program, Amesbury was required to obtain NPDES permit coverage under the 2016 “General Permit for Stormwater Discharges from Small Municipal Separate Storm Sewer Systems (MS4s)” for its stormwater discharges. This permit program was created with the intention of improving the quality of the nation’s waterways by reducing pollutant loads associated with stormwater runoff.  Under this permit, Amesbury is required to develop and implement a Notice of Intent (NOI) and Stormwater Management Program (SWMP), which identifies Best Management Practices (BMPs) the City will implement to address the following six “minimum control measures (MCMs)”:

  1. Public Education and Outreach
  2. Public Participation and Involvement
  3. Illicit Discharge Detection and Elimination
  4. Construction Site Runoff Control
  5. Post-Construction Runoff Control
  6. Pollution Prevention/Good Housekeeping for Municipal Operations

 

Amesbury submitted its Notice of Intent (NOI) to EPA and MassDEP in September 2018 to meet permit requirements which summarized Amesbury’s proposed SWMP to comply with the permit, which is detailed further in Amesbury’s written SWMP Plan originally prepared in June 2019 with updates ongoing. Amesbury submits Annual Reports to EPA and MassDEP by the end of September each year summarizing the progress of its SWMP. The NOI and Annual reports are available on EPA’s website.
