POWELL RIVER, BC — The attempted sale of the shuttered, 100-year-old Powell River pulp mill is proving contentious as the town’s mayor has expressed “shock” at the sales listing and the local Tla’amin First Nation has laid claim to the entire 300-acre waterfront site. Catalyst Paper, part of Paper Excellence of Richmond, B.C. closed the mill permanently last December and, according to Mayor Dave Formosa, subsequently put it on the global real estate market without consulting the city. …According to Formosa, several interested parties had earlier expressed interest in keeping the city’s major tax provider a going concern. …In May, Tla’amin Nation wrote to Paper Excellence laying claim to the Catalyst Paper mill lands, including an adjacent hydro dam on Powell River. …Catalyst replied with a nuanced statement.
