Blue Tee Corp. will pay $1.36 million to clean up a mining Superfund site in Stevens County. The company operated a mine and milling facility near the community of Leadpoint from 1910 through the 1980s, producing nearly a million tons of lead, zinc and barium tailings. In 2003, the federal government spent more than $200,000 on an emergency cleanup of leftover chemicals, 55 gallon drums of hazardous and non-hazardous substances, and PCB-containing electrical equipment.
