This Environmental Impact Statement (EIS) addresses the proposed withdrawal of approximately 310,296 acres of public lands from entry under public lands laws to support the training mission of the U.S. Army National Training Center (NTC) at Fort Irwin, California. The public lands are currently managed by the Department of the Interior, Bureau of Land Management (BLM). Approximately 20,921 acres of intermingled state and private lands would be acquired. Withdrawn and acquired lands would be for the exclusive military use for force-on-force training of armored and mechanized brigades. Significant impacts on public access, soil, air quality, biologic resources, cultural resources, land use, wilderness quality, and transportation are analyzed in this EIS.
