Recently Promulgated Amendments

Effective March 10, 2017, the Massachusetts Department of Environmental Protection (MassDEP) and the Massachusetts Office of Coastal Zone Management have promulgated revisions to the Waterways Regulations, the Designated Port Area (DPA) Regulations and the Municipal Harbor Plan (MHP) Regulations at 310 CMR 9.00, 301 CMR 25.00 and 301 CMR 23.00 respectively.

The changes to the Waterways Regulations are intended to promote and provide greater flexibility for creating public access options to the waterfront in addition to FPAs. MassDEP has created a new category called Facilities of Limited Accommodation (FLAs) that are described in the FLA Regulation Summary below.  Revisions to the Waterways Regulations can be found in 310 CMR 9.52, 9.53 and 9.56 and the definition section at 9.02. 

The DPA regulations promote waterborne commerce and marine industrial use.  The changes to the DPA and MHP regulations are intended to reduce regulatory provisions and increase the flexibility provided to municipalities and businesses, by allowing for new and expanded economic development opportunities while ensuring the protection of current and future marine industrial opportunities in selected areas within DPAs.
