Mason County hyperscale data center campus Approved

The Mason County Fiscal Court gave final approval on May 22, 2026 to rezone 28 properties (2,080 acres, A-2 agricultural to I-3 industrial) outside Maysville for a hyperscale data center campus; the application's development plan shows six data center buildings, three utility substations, and 15 detention ponds on ~1,975 net acres. The developer's identity remains undisclosed, and a legal challenge by residents group We Are Mason County was pending at approval.

What to do next

Next step: Approved — pivot from stopping it to a binding CBA: enforceable caps on noise, water and cost, plus a community benefit.

State environmental permits

Backup generators, water withdrawal and stormwater are permitted by the state, usually earlier and in more detail than anything filed locally.

County & town filings

The rezoning application, site plan, traffic and noise studies, staff report and every revision.

Utility & grid records

The electricity request is filed with the grid operator and the utility long before the town hears about it — and states the real load.

Federal databases

Works anywhere, and covers the operator's record at its other sites.

  • EPA ECHO facility searchEvery federally-reported air, water and waste permit at a facility, plus its inspection and violation history. Search by address or draw a radius around the site. This project's locality centres on 38.600, -83.820 — search that point with a 5-mile radius.
  • EPA EnvirofactsThe same underlying records, queryable by county — useful for 'what else is permitted near this site' rather than one facility.
  • EPA Facility Registry ServiceResolves the shell LLC on a permit to the facility it belongs to. Worth a look when the filing name means nothing locally.

These are places to look, not evidence that anything has been filed. Links were checked on 2026-08-21; search links are queries, not records. What to ask for.

As of August 2026 (2m ago) · changes weekly — re-check before citing

A working set of identified proposals a community can track, not a census — most of the country's activity is not in here yet. Pennsylvania is the exception: its rows are synced from PA DEP's own data-center permit tracker, so the state's coverage is close to complete and carries the permit trail with it. **Each row carries its own provenance.** Rows showing a verification date link to reporting or the governing body's own record and were read on that date; rows marked *unverified* have no source on record — a lead to check, not a fact to cite. **Stage is derived, not asserted.** *Hearing scheduled*, *Awaiting decision*, *Approved* and *Withdrawn* are computed from each row's milestone dates on every rebuild, so a hearing date that has passed stops reading 'scheduled'. Hearings get moved and projects re-file under new names — treat a scheduled date as the earliest to act by, and confirm with the clerk before relying on it. Leads are mined into data/project_candidates.json and promoted here only after a human reads a primary source.
