Rushy Marsh Pond

Rushy Marsh

Covered by Barnstable's watershed permit application, but not a designated Nitrogen Sensitive Area. MassDEP confirmed this in writing on 25 August 2026.

A filing, not a designation. The filing below is real and is recorded in MassDEP's watershed application table dated 11 June 2026. No designated area appears here on MassDEP's NSA address map, and on 25 August 2026 MassDEP confirmed by email — from the Wastewater Management office for Cape & Islands — that Rushy Marsh is not a designated Nitrogen Sensitive Area. The town included it because it is approaching nitrogen abatement comprehensively, working to town boundaries as well as watershed boundaries.

Which source governs? The disclosure form under 310 CMR 15.215(4) turns on designation, not on what a town filed. For a property here, box 4 — not in a Nitrogen Sensitive Area — is the answer. Confirm the address on the map before you sign, and raise anything that looks different with your Board of Health.

And it is not a finding of pollution. MassDEP is explicit that a town applying for a watershed permit does not imply an impaired watershed. The watershed permit is the only mechanism through which MassDEP reviews alternative approaches to nutrient abatement — permeable reactive barriers, cranberry bog reactors and bog restoration — so a town may file for reasons unrelated to water quality where you live.

What the filings mean

Permit application

The town has filed a full Watershed Permit application. That is further along than a Notice of Intent: the plan itself is in front of MassDEP, not just an intention to produce one.

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 here would tick box 4 — the facility is not in a Nitrogen Sensitive Area. Do not tick box 2 on the strength of the filing above: the filing is real, the designation is not. Confirm on MassDEP's address map that nothing is shaded at the property.

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