CASPER — When the Bridger Underground Coal Mine shuts down in November, 92 workers will lose their current jobs, down from the 94 reported by the mine’s owner earlier this month. For Rock Springs, a city of roughly 22,000, the closure is a mass layoff. But it’s an expected one.

“This is not surprising news at all,” said Shannon Anderson, staff attorney with the Powder River Basin Resource Council. “It’s been in the works for years. It really is just partly geology, partly economics. And it is not directly driven by the coal plant retirement decisions.”
