Title

Evolved Expendable Launch Vehicle (EELV) Program, Suppl. EIS

Description

Implementation of the EELV program was previously assessed in the April 1998 Final Environmental Impact Statement, Evolved Expendable Launch Vehicle Program. The proposed Action of the SEIS is to allow the addition of up to five strap-on SRMs to the Lockheed Martin Astronautics (LMA) Atlas V launch vehicle and to allow the use of larger SRMs on the Boeing Delta IV launch vehicle, both of which are part of the EELV program. The launch locations for the Atlas V and Delta IV systems are Cape Canaveral Air Station (AS) in Brevard County, Florida, and Vandenberg Air Force Base (AFB), in Santa Barbara County, California. For the analysis in the SEIS, each contractor is assumed to launch approximately 50 percent of EELV flights involving SRMs (approximately 30 launches per year total). The No-Action Alternative is the previously approved implementation of the EELV program that was analyzed in the 1998 FEIS.
