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
Iowa DNR's September 12, 2024 notice says the application was submitted to operate an existing Computer Processing and Data Preparation and Processing Services facility. Iowa DNR issued final Title V Operating Permit 24-TV-004 on October 17, 2024 for Osmium Data Center at 5855 SW Kerry St; the permit expires October 16, 2029. This establishes an existing permit-defined facility and an unexpired air-operating permit, not current IT load, every-building operation or continuous occupancy.

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.
