Opposition and litigation at this site

Nothing on record as of October 28, 2026. No lawsuit, organized opposition, or contested hearing over Iron Mountain WPA-1 (Boyers underground data center) in Boyers, Butler County, Pennsylvania 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.

Power and water

Iron Mountain's page lists "underground lake & geothermal cooling for reduced energy usage" for the former limestone mine and cites it as the basis of the site's efficiency. As of October 2026, the page does not describe the heat-rejection method, say whether lake water is withdrawn, or give a size for the lake, and no withdrawal or consumption figure is published.

Notes on the record

333,000 sq ft of data center space 220 feet underground in a former limestone mine on a 200-acre campus, about an hour north of Pittsburgh. The operator's page states "40 MW total potential capacity", a potential rather than a firm planned or in-service figure, so no capacity is recorded. As of October 2026, the operator page does not state the energised load. Cleanview's Pennsylvania list gives "Operating capacity 16 MW" for the site, ranked by power capacity; that is a power figure rather than a stated IT capacity, so it is not recorded as operational. Long-standing colocation/records site rather than an AI buildout, no AI classification asserted.

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
Tax abatements or other public subsidy
Permanent jobs promised
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.
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.
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.
