Microsoft Corp-Chicago Data Center

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.

Status as of 5 August 2024: operating Status evidence: Illinois EPA, Office of Environmental Justice; Illinois EPA EJ notification letter dated August 5, 2024, BOA ID# 031807AAN, body paragraphs 2-3; document date 2024-08-05. Status is as of 2024-08-05 and is not a statement about the present: the letter records that the Illinois EPA had received an application to renew Federally Enforceable State Operating Permit 09070018, that the application was 'not requesting changes to the facility or operation', that it was then 'currently under review by the BOA', and that 'This is a computer server facility.'
