A U.S. Appeals Court has ordered the Reserve Mining Company in Minnesota to pilase out its pollution of Lake Superior and its pollution of the air near Minneapolis-St. Paul. Reserve Mining has been dumping an estimated 67,000 tonsof crushed rock - contáining deadly asbestos fibers - into Lake Superior eacli day. Despite the fact that asbestos partióles are believed to cause cáncer, the dumping lus continued för more than two years as the case has slowly worked its way tluough the court system. The Appeals Court in St. Louis ruled that the cotnpany must takc immediáte steps to end its pollution of tlie air: but it granted the company "reasonable" time to end its pollution of Lake Superior. A lower court had ordered tlie plant dosed last year to prevent tlie pollution - but that order was stayed by a higher court.
