Montana Environmental Information Center v. Montana Department of Environmental Quality

Hecla Mining Company and its subsidiaries want to develop two industrial silver and copper mines­­––the Montanore and Rock Creek projects––beneath northwest Montana’s Cabinet Mountains Wilderness. Environmental organizations, in just one of a series of legal challenges to protect high-quality designated resource waters and unique bull trout and grizzly bear habitat, brought an action seeking a declaration that Montana Department of Environmental Quality’s issuance of a permit for the Montanore Project was unlawful. The Montana Supreme Court, in a four-member majority, affirmed the district court’s vacatur and remanded the case to the state agency for further proceedings. The decision is celebrated by environmental groups as a victory to ensure that mines are permitted under Montana’s contemporary water quality standards and nondegradation policy.
