⚠ The environmental review is happening right now — this is the window to demand the full study.  Here's how to weigh in →
Massena, NY · a neighbors' campaign

A 635-megawatt decision shouldn't happen with 11 people in the room.

We're neighbors in Massena — and we don't want a decision this big rushed past us. A Bitcoin and data-center operation has run on the old Reynolds / Alcoa East site since 2017; now the company wants to expand it into one of the largest in the country, on our river, on land we already know is contaminated. We don't want it — and we're backing that up the honest way: with the town's own record, and a demand for the full study before any vote.

One of the largest data centers in the country — decided here, in our town.

We're neighbors in Massena, and we don't want this rushed through. A Bitcoin and data-center company wants a massive expansion on the old Reynolds / Alcoa smelter site on the St. Lawrence — contaminated ground, beside a federal river cleanup. We're demanding the full environmental study, in public, before any vote.

● Updated July 3, 2026 — the environmental review is at its earliest stage and no determination has been made. This is not a done deal.
The numbers

What's actually on the table

Five numbers, straight from the record — the company's own statements to the Planning Board and documented measurements, each with its source.

The number What it means Source
~635 MW The proposed expansion — "expand and modernize" the campus to roughly 635 megawatts of power capacity. The company says — May 21, 2026 minutes
~4× The most recent public figure for the operation's current draw is about 166 MW (late 2024) — the expansion targets close to four times that. Record — the scale, in plain terms
≈70% Of the 912-MW U.S. (NYPA) side of the Massena hydro dam — a size comparison only; the operation says it buys power off the wholesale grid, not from the dam. Record — scale comparison
115 Backup generators in the plan — the company's own number, after what it describes as a reduction from 316. The company says — May 21, 2026 minutes
40 dB vs 50 dB The company predicts 40 dB at the nearest homes. At a comparable crypto site in North Tonawanda, NY, a police study found the plant exceeded that city's 50 dB nighttime limit every night. Company claim vs record — the receipts
Where this would happen

182 & 194 County Road 45 — the former Reynolds / Alcoa East smelter campus. On the St. Lawrence River. Beside a federal river cleanup. In our town.

Why we don't want it

Three problems that don't go away

Each one is laid out with its source on the Resources page — and each one is a reason this deserves the full study, not a rushed sign-off.

01

It sits on contaminated ground

The site is contaminated former-smelter land — PCBs, dioxins, and metals capped and contained in place, right beside a federal river cleanup. Heavy construction raises real questions about whether that cap stays intact.

02

It never turns off

The company says its studies show 40 dB at the nearest homes — but that already sits at the WHO threshold where nighttime noise begins to harm health. A comparable crypto site in North Tonawanda, NY exceeded its city's 50 dB night limit every night. We want worst-case modeling, not one reassuring number.

03

Your bill is on the table

A 635-MW load is enormous. When a crypto operation scaled up in Plattsburgh, NY, residents' bills rose and the city became the first in the U.S. to pause mining. Who pays for grid upgrades here, and what happens to local rates?

The momentum

A month ago, eleven people were in the room. Then—

This is moving, and it's moving because neighbors started paying attention. Dated and sourced, like everything here.

Residents gathered with signs outside Massena Town Hall at the June 29 rally
June 25, 2026 · where it started

Eleven people, one enormous decision

A make-up meeting noticed barely a day ahead — at first with the wrong date — drew about a dozen residents while the Planning Board began its review of the data-center application. Nothing was approved; the board even sent a threshold question to the Zoning Board of Appeals: whether a large data center is a permitted use in that zone at all. The full recap →

Then the steps of Town Hall filled

Several dozen residents — families, elders, and the Akwesasne Mohawk community — packed an emergency rally organized by Mohawks United in Safety and Health. Far more people than the meeting itself drew. The report + photos →

July 8, 2026 · next door

Now our neighbors in Canton are acting

Canton holds a July 8 public hearing on a moratorium that would pause large data centers through May 2027 — and the St. Lawrence County Legislature has affirmed that siting authority rests with towns, urging every municipality to consider a pause. Massena has that power too. The report →

On the Governor's desk

A statewide one-year data-center pause awaits a signature

The Responsible Data Center Development Act passed both houses of the New York Legislature on June 4 and awaits Governor Hochul's signature. It is not yet law. Ask her to sign it →

“This room is going to be full when we have a public hearing.”
— the Planning Board's own words, June 25, 2026 · from the meeting recap
Let's make that true.
Take action

Three ways to be heard. Pick one.

You don't need to be an expert — every action here is timed so you know exactly what it costs you.

01Get on the record ~3 minutesCopy the ready-made letter demanding the full study and email it to the Town Clerk. Written comments become part of the record.
02Show up one eveningPublic hearings are still required. The next date posts here the moment it's set — a full room changes how a board votes.
03Bring five neighbors ~90 secondsSend this site to five people in Massena. Eleven people in the room is how this almost slipped past everyone.
