AWS Calvert Technology Center Withdrawn
Eight data center buildings (266,000-332,000 sq ft each) proposed at 1650 Calvert Cliffs Parkway on Constellation-owned parcels near the Calvert Cliffs nuclear plant. AWS formally withdrew the concept site plan on Aug 4, 2026 - after first-round county review comments and before any resubmission. Timeline documented on the county's own project page.

State environmental permits
Backup generators, water withdrawal and stormwater are permitted by the state, usually earlier and in more detail than anything filed locally.
- Maryland Dept. of the EnvironmentThe program page: which permits this state requires, and the office that issues them.
- Search Maryland Dept. of the Environment 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 Lusby (Calvert 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 Lusby (Calvert 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.
- PJM Interconnection (Mid-Atlantic, Ohio Valley) — 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.
- Maryland 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 38.420, -76.450 — 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.

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.
