Massachusetts Stormwater Management Updates Advisory Committee

In preparation for updating the stormwater provisions of the Massachusetts Wetlands Protection Act and the Massachusetts Stormwater Handbook, MassDEP has convened a Stormwater Advisory Committee.

MassDEP is convening a stormwater Advisory Committee (AC) in preparation for updating the Massachusetts Stormwater Handbook and the Massachusetts Wetlands Protection Act (WPA) stormwater regulations (310 CMR 10.05(6)). MassDEP is undertaking these updates as part of its mission to protect wetland and water resources of the Commonwealth. The Advisory Committee will focus on two topics:

  • Aligning the WPA Stormwater Management Standards with Municipal Separate Storm Sewer System (MS4) General Permit Post-Construction Stormwater Rules 

MassDEP is developing measures that will more closely align the WPA stormwater management standards in wetlands areas with MS4 General Permit stormwater rules. These measures are expected to provide consistency between federal and state regulations, simplify the stormwater permitting process, and help the 260 MS4 communities meet the MS4 deadline to adopt local rules that meet EPA’s Minimum Control Measures. Alignment of the stormwater regulatory frameworks will also provide benefits that improve resilience for wetland ecosystems and for drainage and transportation infrastructures under changing climate conditions.

  • Precipitation Projections for Stormwater Management

MassDEP is preparing to update the Wetlands Protection Act stormwater regulations pertaining to precipitation intensity and frequency by, at a minimum, adopting the NOAA Atlas 14-Precipitation-Frequency Atlas of the United States Volume 10 Version 3.0: Northeastern States. This will address related stormwater management issues and broader climate resilience implications by incorporating the most recent storm data. MassDEP is also considering options for incorporating precipitation projections that account for future conditions.

MassDEP will also update the Advisory Committee on additions to the MA Stormwater Handbook such as the MassDEP Wetlands Program Solar Array Policy and special considerations being developed to address constraints imposed by limited Rights of Way (ROW) on MassDOT linear highway projects.


The purpose of this Advisory Committee process is to inform and seek input from interested stakeholders about proposed changes to MassDEP’s stormwater regulations and Handbook. The Advisory Committee comprises designees from invited organizations that represent interested stakeholders, including from the development, environment, and government sectors, as well as other subject matter experts. All meetings are open to the public.
