## Summary

A May 4, 2026 letter from Utah Department of Environmental Quality deputy director Ashley Sumner to the Box Elder County Commission describes air-quality, drinking-water, and water-quality permitting requirements for the proposed data center and supporting power plant.

## Useful Claims

- The letter says the developer must obtain an air-quality Approval Order before construction can begin.
- It says no air-quality Notice of Intent had been submitted as of May 4, 2026.
- DEQ expected separate public water systems for the data center and power plant based on its understanding at that date.
- It says permits are required for surface-water and groundwater discharges to waters of the state.

## Reliability Notes

This is an official DEQ letter published in Box Elder County's document center and is primary for the agency's stated requirements and the submission status on the letter date. It is not a permit decision, a complete project description, or evidence that the project later submitted or received permits.
