EVANSTON (WNE) — Local emergency crews were kept busy over the weekend after a fire broke out at the Silver Eagle Refinery east of Evanston.

According to a press release issued by Uinta County Fire and Ambulance, fire and emergency medical services crews were dispatched to the area at about 10:30 on the morning of Saturday, Sept. 19, after an explosion at the loading rack area of the refinery.

The release said two trucks were loading at the time of the explosion, but the resulting fire was contained to the loading facility and there was no damage to the refinery itself.

The loading facility structure collapsed in the fire.

All roads in the area were closed to the public while crews responded.

Because it was contained to the loading facility, fire crews were able to let the fire burn itself out while maintaining protection for other structures and facilities.

Fire Deputy Tim Overy said there was still continuing burn-off at the loading area as of Monday morning, but the fire was contained and controlled.

Two drivers who were in the loading area at the time of the explosion were transported to Evanston Regional Hospital with burn injuries. Overy said one of those individuals was subsequently transferred to the burn unit at the University of Utah Medical Center.

The cause of the explosion is still under investigation.
