The 70,000-acre Substation fire, threatening 900 homes in Sherman County, became the top priority fire in the nation Thursday, an official said. It was 15 percent contained as of Friday morning.

That designation, due to the amount of homes threatened, added 60 personnel to the fire from the Pacific Northwest Incident Management Team. They joined 217 firefighters from 73 fire agencies. Air support and dozers earlier joined in suppression efforts.
