The Department of the Army (Army) intends to prepare a Legislative Environmental Impact Statement (LEIS) to assess potential impacts of the continued military use of withdrawn lands in Alaska. The current withdrawal will expire in 2026 unless Congress enacts legislation to extend it. The information presented in the LEIS will inform the legislative proposal submitted to Congress by the Army and support Congress’ decision on the proposed action. The U.S. Bureau of Land Management (BLM) has agreed to be a cooperating agency in preparation of this LEIS.
