All vehicles on the premises are powered by diesel motors to minimize interference by ignition systems.[5][6]. ngVLA Copyright 2009 Associated Universities, Inc. To aid in limiting outside interference, the area surrounding the Green Bank Observatory was at one time planted with pines characterized by needles of a certain length to block electromagnetic interference at the wavelengths used by the observatory. As part of the process of building a final concept for the ngVLA, NRAO launched the ngVLA Community Studies program, allowing members of the scientific and engineering communities to become major contributors to this effort. The debris from the collapse was cleared by June 1989, and West Virginia Senator Robert C. Byrd would pioneer a campaign in Congress to replace it with the Green Bank Telescope, construction for which began in 1990.
