LIVINGSTON, Montana — R-Y Timber Inc. is shutting down its sawmill in Livingston about a week after a structure fire broke out at the site, the company’s general manager confirmed on Tuesday. R-Y Timber General Manager Dan Richards said a structure fire destroyed the yard’s planer on Sept. 12. That set operations back, but the company immediately decided to rebuild. The company was four to five weeks away from starting up a new planer when another fire sparked in the early morning hours on Feb. 7. This time, the flames damaged the mill itself, taking out the roof, according to Richards. Because of the challenges, R-Y Timber decided to close its Livingston mill, where approximately 70 employees work. Richards said the company is preparing to lay off quite a few people around the end of the week, though it aims to keep some workers to organize and clean up.
