Public Comment Period Extended for MassDEP Title 5 and Watershed Permitting regulatory amendments

Good Afternoon-


This email is to inform you that, in response to requests made during the public hearings, the public comment period for the Massachusetts Department of Environmental Protection’s (MassDEP) draft amendments to the Title 5 regulations, 310 CMR 15.000, and the new, related Watershed Permit regulations at 314 CMR 21.00, has been extended until January 30, 2023 and MassDEP will be hosting two additional Public Hearings:


Remote Only, January 24, 2023 at 6:00 p.m. Register at:

Remote Only, January 25, 2023 at 6:00 p.m. Register at:


Oral comments will be received at the above public hearings in January 2023 and written comments can be submitted via email to  Please put “Title 5 and Watershed Permitting” in the subject line. Written comments may also be submitted by mail and should be sent to MassDEP, Bureau of Water Resources – Division of Watershed Management, 100 Cambridge Street, suite 900, Boston, MA 02114, Attention: Title 5 & Watershed Permit. 


MassDEP also intends to hold two additional information sessions on: January 17, 2023 at 6:00 p.m. (remote) and January 18, 2023 at 6:00 p.m. (hybrid). More information about how to participate in these sessions will be provided on MassDEP’s website.


MassDEP has proposed these amendments and regulations to enhance protection of embayments and estuaries—particularly on Cape Cod, the Islands, the southern portion of the South Shore and the South Coast in Southeastern Massachusetts—from nitrogen pollution originating primarily from wastewater. The proposed amendments will allow MassDEP to designate new Natural Resource Area Nitrogen Sensitive Areas (NSA) and add nitrogen reduction provisions within these areas for Title 5 systems.  The new Watershed Permit regulations at 314 CMR 21.00 provide a voluntary watershed permitting approach for communities to control nitrogen and other pollutants from entering the embayments and estuaries. 


The draft regulations are published on the MassDEP website at: and at: 310 CMR 15.000: Septic Systems ("Title 5") | and 314 CMR 21.00: Watershed Permit Regulations | 


Recordings of previously held information sessions and public hearings can also be found here: 310 CMR 15.000: Septic Systems ("Title 5") | 


Please refer your constituents to these web page locations for up-to-date information pertaining to these amendments and draft regulations.
