WAPR is a public register of where AI computing physically sits. This page is one building that volunteers have mapped as a data centre — the map records what kind of building it is, not what runs inside it, so it may host AI, cloud or ordinary corporate servers. Everything below comes from OpenStreetMap, the volunteer-made public map, and is republished as recorded — including the operator tag, which is what mappers entered rather than a check of who runs the building today. Fields nobody recorded are shown as “not recorded”, never guessed. What WAPR is →

This record is what OpenStreetMap contributors have mapped and tagged as a data centre — nothing more. WAPR republishes it verbatim with provenance; fields the mappers did not record are shown as such, never inferred.

What the public record says

how this is known

as old as the oldest of Mapped facilities, Interconnection facilities, Crane filings, Virginia regulated sites, Permitted water discharge, Generators at sites (EIA-860M/923)

Each line is a public document that marks a step in this site’s life — a rung, in the register’s terms — with its date and what kind of date it is: the document’s own, a state the record shows already held on that date, or the day WAPR first saw the record.

2026-01-03on or beforecrane notices filed beside it — FAA obstruction evaluation case file: the first filing within 1 km of any register object of this crane site (the objects sharing its name, operator and country, each within 3 km of another member), one calendar-year window (0 m from the pin)
20 filings within 1 km, last 2026-10-14, distinctive
FAA case files are read one calendar year at a time and the 2025 FAA year file was joined against a different register than the 2026 file the crane dates come from, so a filing near an object one register lacks cannot be counted — re-derive it (collectors/faa_part77.py --rederive 2025), so the first 2026 filing cannot be shown to be when this site's filings began
figures restated 2026-10-28: previously censored by FAA case files are read one calendar year at a time: 7 crane filing(s) within 1 km of a register object of this crane site, or within 1 km of the mapped site, are already in the 2025 file, so the first 2026 filing is not when filings began; filings prior window 7

The register’s rungs are: mapped · listed in the network registry · crane notices filed beside it · on an air regulator's books · holds a discharge permit · generators recorded emitting · a generator within 250 m produced power · interconnection · operating load. Rungs not shown for this site are rungs no public document has put it on. Interconnection and operating load are never written until a primary record exists.

Straight-line joins to federal layers: HIFLD transmission and retail service territories (2023 vintage), USGS principal aquifers (1:2.5M), USGS NHD named flowlines. They say what surrounds the site, never what it draws, pumps or discharges. A territory says who sells retail power there; a line passing a site is not a line serving it.

Air permit

feed checked 2026-11-01 09:18 UTC data permit status as EPA's ECHO held it on 2026-11-01

No air-permit source within 500 m carries the data-centre sector code in ICIS-Air. WAPR reads only the ICIS-Air sources a state has coded NAICS 518210 or SIC 7374, so this is not proof the site has no permit.

Water discharge

feed checked 2026-11-01 09:21 UTC data monitoring periods from 2025-10-31 to 2026-10-31 fetched 2026-11-01

No discharge permit coded to the data-centre sector within 500 m. Most cooling water leaves as vapour and to the sewer, not through an outfall, so a site with no discharge permit on record is not a site that uses no water.
