Opposition and litigation at this site

Nothing on record as of September 14, 2026. No lawsuit, organized opposition, or contested hearing over Pontoon Bridge Road Data Center (proposed) in Massena, St. Lawrence County, New York appears in the sources this registry tracks. That is an absence in our sources rather than a finding that none exists, and local opposition often predates any coverage a national dataset would pick up.

If you live near this site and something is happening that this page does not show, that is worth telling us. Send us the document and it goes in the record with the source attached. For sites where opposition is already established, see every contested site we track.

Notes on the record

One of four Massena-area data-center initiatives named in May 2026 local coverage of the NYISO large-load requests (alongside an NCCS expansion, a former-Sears conversion and a Petawatt Holdings substation). No megawatt figure is recorded here: a 250 MW interconnection request is attributed to this project by a third-party tracker whose capacity fields are behind a paywall and could not be read, and the news account's only stated figure, 1,935 MW as the largest pending request, is not attributed to any named project. Entity-name spelling varies between sources ("American Data Center Partners LLC" / "American Data Centers Partners, LLC"). Coordinates are a street-address geocode.

What the record does not establish, and the document that would

In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.

Power capacity in megawatts
Cooling method and water use
Tax abatements or other public subsidy
Permanent jobs promised
Land area
How the community has received it
Which utility serves it

Which document closes each gap

Power capacity in megawatts: The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.
Cooling method and water use: The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
Tax abatements or other public subsidy: The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised: The economic development application or incentive agreement, which usually states a job commitment and a clawback.
Land area: The rezoning application, the plat, or the deed recorded with the county.
How the community has received it: Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.
Which utility serves it: The electric service agreement or the utility's filing with the state public utility commission.

Have one of these documents? Send it to us and we will add it to the record with attribution.

Distances are between recorded coordinates, many of which are a city or county centroid, so treat them as approximate. Cumulative load on one utility and one aquifer is the question a planning commission rarely asks.
