A Canadian timber company will shut down operations at its Philomath sawmill, eliminating about 100 jobs in the small community west of Corvallis, Interfor Corp. said Friday. It will become the third Oregon sawmill to close since the start of the new year. Hampton Lumber closed its Banks mill and laid off 58 in January while Rosboro Co. temporarily closed its Springfield mill and laid off 25 in early February. …Interfor bought the Philomath mill in 2021 from Georgia-Pacific, saying at the time that the purchase would “support accelerated growth,” according to the Philomath News. …Nick Smith, spokesman for the American Forest Resource Council, a timber trade group, said he was worried that “more pain is coming. The common thread between these mill closures is high log costs driven by low log supply thanks to policy decisions at the state level,” Smith said.
