Amherst is working to implement a 5-year Stormwater Management Program required by the Phase II MS4 General Permit. Phase II local governments are required to develop and implement a stormwater management program that includes the following six minimum measures:
Public Education and outreach on stormwater impacts
Public involvement and participation
Illicit discharge detection and elimination (IDDE)
Construction site stormwater runoff control
Post construction stormwater management for new development and redevelopment
Pollution prevention/good housekeeping for municipal operations

Currently stormwater management design for new development and redevelopment, and construction site run off in Amherst is regulated under the Massachusetts Wetlands Protection Act and the Town of Amherst Wetlands Protection Bylaw and Regulations. Amherst is in the process of developing a new stormwater bylaw and regulations. Construction sites over one acre are also regulated under the National Pollutant Discharge Elimination System (NPDES) Stormwater Discharges Construction Activities program with the EPA. See the resources listed below for information on permitting and stormwater management technology.
As required by the NPDES MS4 General Permit, Amherst’s current Stormwater Management Program and latest MS4 Annual Report can be accessed by the public through the links provided in the column to the right. Please submit any comments on either document to Beth Willson at email@example.com.
