SEELEY LAKE — Pyramid Mountain Lumber may still have a chance to stay open, but it would take nothing short of a miracle. The company, which announced its impending closure on March 14, said it needs one of two things to stay in business: tens of millions of dollars in investment into automation, or roughly 50 more employees to return the mill to full operational output and increase revenues. …While the money for automation is non-existent within the company, the lack of employees stems from Seeley Lake’s longtime standoff with the county government over a community sewer system that’s stifling affordable housing. …The health department told the Missoulian that such restrictions are necessary to limit groundwater contamination from nitrates, and doubled down that the real solution is a public sewer system. …Seeley Lake had the opportunity to build a $12 million sewer system and $5 million collection system in 2021.
