How the community has taken it

Uinta County Commissioners unanimously approved the conditional-use permit but attached 15 conditions after hearing both resident opposition (an 8-signed-page petition citing environmental and tourism-visibility concerns) and resident support at the hearing.
Power and water
Fully islanded on-site microgrid generating power through natural gas engines and turbines, avoiding interconnection-queue exposure and ratepayer impact.
Cooling uses a water-glycol coolant mixture that is trucked in and lasts about six years before replacement, so the facility does not draw groundwater or surface water for cooling and will not use water from the nearby Bear River. A private on-site well supplies plumbing water only.
