"SODA SPRINGS, Idaho -- As it races to replenish phosphate supplies for its weed-killing cash machine Roundup, Monsanto Co. insists its history of polluting southeastern Idaho’s high country shouldn’t prevent it from digging fresh open pits here.
Three of the St. Louis-based chemical company’s previous mines in this region of broad valleys and forested ridges are under federal Superfund authority; a fourth is now violating federal clean water laws. In all, several companies are responsible for polluting at least 17 sites southwest of Yellowstone and Grand Teton national parks.
With its current mine in the region nearly played out, Monsanto now wants federal regulators to let the company open a new one by 2011, contending safeguards on the project will keep poisons out of the Blackfoot River. The trout stream just a few hundred yards away is among 15 southeastern Idaho waterways where selenium that leaked from mines exceeds legal state levels."
