INL provided an update on the Sheep Fire: Last Monday, a bolt of lightning sparked the biggest fire in INL history. Over the course of six days, firefighters across eastern Idaho diligently fought the Sheep Fire, and we are happy to report that by Sunday, July 28, the fire was completely extinguished with no remaining hot spots.
The Sheep Fire burned 112,107 acres of grassland and sagebrush, all on INL’s desert site. No injuries were sustained, and all curtailed employees were back to work by Thursday, July 25. No buildings or structures were burned. Although a number of power poles were destroyed, Rocky Mountain Power and INL have crews currently working to replace the damaged lines, and no commercial power to INL facilities was lost during the course of the fire.
Successfully containing and extinguishing the Sheep Fire was an effort that involved the support of a number of agencies. We would like to thank and recognize the following for their assistance: The Bureau of Land Management Idaho Falls District, United States Forest Service—Caribou-Targhee National Forest, Beaverhead-Deerlodge and Custer-Gallatin—Inkom Fire Department, Teton Fire Department, Madison Fire Department, Ammon Fire Department, Ucon Fire Department, Idaho Department of Lands, Roberts Fire Department, Hamer Fire Department, West Jefferson Fire District, South Fremont Fire District, Idaho Falls Fire Department, Central Fire District, Private Contractor CJL, Mud Lake Oil and Rocky Mountain Power.
“In addition to the outside agencies who lent their support during the Sheep Fire, I would also like to personally thank the firefighters who worked around the clock in harsh conditions to contain the fire,” said Juan Alvarez, INL Chief Operations Officer. “I’d also like to extend my gratitude to all those behind the scenes who provided their support.” #SheepFire
