The towns here did not file the same way. Two properties in this watershed can sit in different legal positions depending on which side of a town line they fall. If you are near a boundary, the town matters as much as the watershed.

What the filings mean

Notice of Intent

The town has filed a Notice of Intent: a commitment to apply for a Watershed Permit later, on a schedule approved by MassDEP. It pauses the clock. It does not stop it.

De Minimis application

The town has applied for a De Minimis Load Exemption — a separate legal route arguing the nitrogen load from this area is too small to warrant the upgrade requirement.

Because these are applications rather than granted permits, the suspension is conditional. A town that misses the milestones in its approved schedule can have the five-year upgrade clock started by MassDEP — running to 8 July 2030.

Selling a property here

On the MassDEP nitrogen disclosure form, a seller in Green Pond would normally tick box 2 — located in a Nitrogen Sensitive Area, but not subject to the upgrade requirement because a filing covers the watershed — and name the filing for their town above.

Separately, a passing Title 5 inspection is required before transfer, as it is everywhere in Massachusetts. How the disclosure works →
