Arizona AG Wins Binding Pause on Surprise, AZ Warehouse-to-ICE-Detention Conversion Pending Environmental Review

Arizona AG Kris Mayes announced July 1 a binding stipulated agreement with DHS and ICE pausing all conversion work on the Surprise, AZ warehouse — a 418,400 sq ft industrial facility ICE purchased for approximately $70M in January 2026 (2026-01-23–dhs-purchases-rockefeller-surprise-az-warehouse). ICE cannot detain anyone or take further physical conversion steps until a federal environmental assessment is completed; Mayes’s office projects a minimum nine-month delay. The site sits directly across from a chemical storage facility, and Mayes had filed the underlying NEPA lawsuit in April. This is the first instance of a state AG winning a binding pre-construction pause on the warehouse-to-detention conversion program nationally.

The pause lands atop a site with an already-documented capture history: the $313M GardaWorld operating contract (2026-03-06–ice-awards-gardaworld-313m-surprise-arizona-contract) and the Rockefeller Group’s 483%-markup sale to DHS, where City of Surprise’s local detention ban was nullified by federal preemption. The NEPA pause is a delay mechanism, not a cancellation — the underlying 1,500-bed build-out remains authorized pending the review’s outcome.
