The U.S. Department of Agriculture, Forest Service, will prepare an Environmental Impact Statement (EIS) to consider the proposal to create additional tailings and waste rock disposal capacity and related infrastructure at the Greens Creek Mine on northern Admiralty Island on the Admiralty Island National Monument, Tongass National Forest. The proposed action provides for an expansion of the existing tailings facility area to the south for an increase of approximately 200 acres. This would include an increase of about 60 acres for tailings placement and an addition of approximately 140 acres for supporting infrastructure.
