State environmental permits

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

• Mississippi DEQ — Air DivisionThe program page: which permits this state requires, and the office that issues them.
• Search Mississippi DEQ — Air Division for this projectsearchThis state publishes no searchable permit database, so a written records request to the agency is the reliable route. Use this search only to find the right office.

County & town filings

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

• Search Madison County 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 Madison County 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.

• MISO (Midwest & Gulf) — interconnection queueRequested megawatts, queue position and target in-service date. The MW here is the real number; the one at the town meeting is often phase one.
• Mississippi Public Service 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 32.630, -90.030 — 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.
