In issuing permits for expansion of a key Montana coal mine, state regulators have consistently ignored water quality laws, the Montana Supreme Court ruled Wednesday as it vacated a permit for Rosebud Mine.
The ruling is likely to undo three different mine expansion permits granted to Rosebud Mine by Montana’s Department of Environmental Quality. The southeast Montana mine, owned by Westmoreland Mining LLC., feeds Colstrip Power Plant.
