DHS Retains Contractor for Surprise AZ Environmental Review; GardaWorld Deal Worth $700M With Extensions

DHS disclosed on September 6, 2026 that it has retained a contractor to assist with the environmental review of the Surprise, Arizona ICE detention warehouse, and has begun working with that contractor including an introductory meeting. This is the operative compliance step under the stipulated agreement Arizona Attorney General Kris Mayes secured on July 1, which paused all conversion work pending a federal environmental assessment.

Two details qualify the disclosure. The filing does not name who was hired. And the City of Surprise reports that its staff met with a GardaWorld representative seeking information for the assessment — GardaWorld being the contractor already holding the renovate-and-operate contract for the facility. Whether GardaWorld is conducting the environmental review of the project it is paid to build, or merely supplying information to a separate reviewer, is not resolved by the reporting, and the distinction is the whole question about whether the review is independent.

The contract is larger than the figure usually cited. GardaWorld’s agreement is $313.4 million to renovate and operate, with a possible extension through early 2029 that would make it worth more than $700 million. This corpus has recorded the $313M award since March; the extension ceiling has not previously appeared here.

A correction to the stop-work chronology. The capture ledger placed the stop-work order on April 27, “at least two days before the AG filed suit.” Contract-modification records reported by Project Saltbox date it earlier: modification P00001, signed April 22, initiated the halt, and P00002, signed April 23, carried the explicit description “THIS MODIFICATION UPDATES THE STOP WORK ORDER IN EFFECT AT THE SURPRISE PROCESSING AND DETENTION FACILITY.” The order was later rescinded. The sequence still supports the point the ledger was reaching for — work stopped before Arizona sued, not because of it — but by a wider margin than stated, and on documents rather than inference.

Read against the Gilroy preliminary injunction six days later, the two Western cases show NEPA operating as the binding constraint on detention buildout where local zoning cannot reach a federal facility. The difference is the posture: Arizona got a negotiated stipulation and is now watching compliance proceed slowly; California got a contested injunction with a merits finding.

Sourcing note. The contractor retention, the unnamed-hire gap, the GardaWorld meeting with city staff, and the $700M extension ceiling are from Arizona Capitol Times and KJZZ. The P00001/P00002 modification dates and descriptions are Project Saltbox’s reading of contract records and were not independently pulled from a federal award database here; a USASpending or FPDS check on the GardaWorld contract would confirm both the modification dates and the extension value.
