IN 1872, President Ulysses S. Grant signed a mining law to spur the development of the West by giving hard-rock mining precedence over other uses of federal land. But the law has long since outlived its purpose, and its environmental consequences have been severe.
Mining claims for copper, gold, uranium and other minerals cover millions of those acres, and the law, now 140 years old, makes it nearly impossible to block extraction, no matter how serious the potential consequences. Soaring metal prices are now driving new mine proposals across the West.
Oregon’s Chetco River is one example. The river’s gin-clear waters teem with wild trout and salmon, including giant Chinook salmon tipping scales at more than 60 pounds. In 1988, Congress designated the Chetco a national wild and scenic river “to be protected for the benefit of present and future generations.”
But the river is now threatened by proposals to mine gold along almost half of its approximately 55-mile length. Suction dredges would vacuum up the river bottom searching for gold, muddying water and disrupting clean gravel that salmon need to spawn. Despite the Chetco’s rich fishery and status as a wild and scenic river, the United States Forest Service is virtually powerless to stop the mining because of the 1872 law.
As Michael P. Dombeck, a former chief of the Forest Service, explained to a Senate committee in 2008, “it is nearly impossible to prohibit mining under the current framework of the 1872 mining law, no matter how serious the impacts might be.”
Under the law, mining companies — not the government — decide whether and where to file their claims on public land. (National parks, monuments and wilderness areas are excluded.) Federal agencies review the plans, but they are approved as a matter of course. Mining companies pledge to protect rivers threatened by their operations. But the industry’s track record hardly inspires confidence.
The Environmental Protection Agency estimates that headwater streams in 40 percent of Western watersheds are polluted by mining. A scientific review in 2006 of 25 modern Western mines by the environmental group Earthworks found that more than three-fourths resulted in water contamination. Over all, the E.P.A. has estimated that it will cost $20 billion to $54 billion to clean up abandoned mine sites.
As fisheries scientists, we are deeply concerned about the impact mining has had on our nation’s dwindling fisheries and the inadequacy of the 1872 law to regulate modern mining. In contrast to the pick-and-shovel operations of a century ago, most modern mines are large-scale operations that use toxic chemicals to extract metals from the ore, and they generate vast amounts of mine waste. After these mines close, treating the polluted water in perpetuity is often necessary.
At Oregon’s Formosa mine, for instance, toxic metal-laden drainage from mines is contaminating 18 miles of prime salmon habitat. In Montana, the Zortman Landusky Mine has polluted a dozen streams with arsenic, selenium and other harmful metals. The acidic runoff will continue for centuries.
