OSM way/1426146790 · no name or address is mapped, so it is titled by its operator tag and region
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
feed checked 2026-09-14 05:15 UTC (oldest of 6 instruments)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.

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.

- USGS National Hydrography Dataset, Flowline — Small Scale (layer 4), named features only (US Government work, public domain) — straight-line distance to the nearest NAMED stream or river; a reading beyond 30 km carries beyond_30km, and a site with none in the widest search carries no waterway
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.

Tons per year accepted into EPA's National Emissions Inventory for the facility — the only national per-facility emissions number for the sector, only as complete as what each state submitted and WAPR's data-centre filter.
Water discharge
feed checked 2026-11-01 09:21 UTC data monitoring periods from 2025-10-31 to 2026-10-31 fetched 2026-11-01No 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.
Generators within 1 km (EIA)
feed checked 2026-11-02 03:29 UTC data generators as listed in EIA-860M for 2026-08; output from EIA-923 over the last 12 months EIA's data service returned for each plant, windows ending between 2022-12 and 2026-08 — each plant's months are printed on its row · ended 2026-08-31 fetch time not statedNo EIA-listed generator within 1 km. EIA lists grid-connected units of 1 MW or more; behind-the-meter plants that never interconnect are not obliged to file.
