What to do next

Next step: Already operating — the leverage now is enforcement: noise and water conditions, tax revenue tracking, and any expansion filing, which reopens the record.

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.

  • Search Mesa planning filingssearchPlanning departments post application files under many different names. Find the department, then ask the clerk for the application number — that number unlocks everything else.
  • Search Mesa property records / GISsearchThe parcel record names the buying LLC and the sale date, which is what ties an anonymous filing to an operator.

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.

  • No organised market covers this statenoteThere is no public queue to read. The record is the utility's integrated resource plan and its filings at the PUC — plus FERC eLibrary for anything federally docketed.
  • Arizona Corporation Commission — docket searchSpecial contracts, large-load tariffs and rate cases are docketed here. Testimony and exhibits are public, and are usually more candid than the press release.
  • FERC eLibraryFederal filings: transmission agreements, interconnection service agreements, and co-location disputes.
  • Search the serving utility for a will-serve lettersearchThe will-serve or load-service letter is the utility's own written commitment. Ask the utility and the PUC for it by name — it is frequently the first document to exist.

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 33.420, -111.830 — 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.
