Supplemental Environmental Impact Statement for the Evolved Expendable Launch Vehicle Program

摘要

The EIS was prepared to analyze the potential environmental consequences of the Proposed Action and No-Action Alternative. The Proposed Action is to allow the addition of up to five strap-on solid rocket motors (SRMs) to the Lockheed Martin Corporation (LMC) 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 Force Station in Brevard County, Florida, and Vandenberg Air Force Base, in Santa Barbara County, California. For the analysis of the FSEIS, 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.
