This page joins every source layer DataCenterData holds for one site unit. Each value says which layer stated it and when. Layers are shown side by side and never reconciled into one status; capacities of different kinds are never added together.

What the sources support
An Illinois EPA environmental-justice letter dated 5 August 2024 names Microsoft Corp-Chicago Data Center at 601 Northwest Avenue, Northlake, as a computer server facility and records a then-pending application to renew Federally Enforceable State Operating Permit 09070018 without requested changes to the facility or operation. That letter supports operation as of 5 August 2024. The later source-retrieval date is only when the source was retrieved. Current operating status is not independently established.

What remains unknown
- critical IT capacity
- building count
- county
- owner and operator as named roles
- whether the DCEO Data Center Investment Program row Microsoft Corporation / 2021 / Northlake is this facility (the 2025 and 2021 DCEO annual reports were read in full and do not publish a street address that would confirm or exclude the match)
- the later outcome of FESOP 09070018 (the Bureau of Air public-notice search endpoint was not successfully queried: the HTML pages return an empty table and populate results by HTTP POST, which was not run)

Facts
Quote-bound facts: each shows the value, the source address, the capture hash (first 12 characters; the full SHA-256 is in the page markup) and the capture date. The source's exact wording stays in the capture record and is not republished here; the capture hash binds it.
No quote-bound fact with a hashed capture is recorded for this facility.
