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Microsoft Corporation / 2021 / Northlake is this facility (the 2025 and 2021 DCEO annual reports were read in full and do not publish a street address that would confirm or exclude the match)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)
