ACTION: Finding of No Significant Impact

Assessment (EA) to analyze the potential environmental consequences of building three In-Flight Interceptor Communication System Data Terminals (IDTs) at Fort Dnim or Niagara Falls Air Reserve Station (ARS), New York. Within the Department of Defense, the MDA is responsible for developing and fielding a Ballistic Missile Defense System (BMDS). The BMDS is designed to intercept threat missiles during all phases of flight: boost, midcourse, and terminal. Ground-Based Midcourse Defense (GMD) is an element of the BMDS, which employs Ground-Based Interceptors (GBIs) to intercept and destroy long-range ballistic missiles during the midcourse phase of their flight before their reentry into the Earth's atmosphere. The Proposed Action is needed to provide a communications link that will help guide the GBI to its target
