Additional details about the deal, which was finalized this week, will be released during Gov. Steve Bullock's fire briefing in Butte Friday.

The helicopters were barred last year from responding to fires in national forests and U.S. Bureau of Land Management land because federal standards require they use smaller buckets to scoop water. The issue sparked tension between state and federal officials with a shortage of resources available to fight blazes during an active fire season last year across the West.

The five modified Bell UH-1H helicopters have increased power that enables them to carry 324-gallon buckets. However, U.S. Forest Service policy, developed after helicopter crashes in the past, requires aircraft of that type to carry water-scooping buckets 100 gallons smaller.

The issue is specific to Montana's helicopters and not any other state's aircraft of equipment, Forest Service officials previously said.

This ambulance is painted different, following the Baylor Scott &White scheme of blue and yellow. Chuck Pearson, director of Scott & White Emergency Medical Services, said the box is a little bit larger than current vehicles and allows 360-degree access to the patient.

Scott & White is moving toward this style of ambulance and has two others on order that will arrive in June, he said. Two or three more will likely be ordered in July to arrive in December.

These ambulances can be remounted where the box is taken off and placed on a new chassis.

The driver suffered minor injuries and was taken to an area hospital. That person is expected to be OK.

No one was in the ambulance at the time of the crash, officials said.
