This report identifies alternative corridors of land within which transmission lines could be routed and details various impacts on the environment which would be associated with introduction of transmission facilities. Many alternative corridor locations were identified (see Figure 1-1). Identification of these alternative transmission corridors was a complex process, since the number of potential corridors capable of connecting the various substations was myriad; the \u27least desirable\u27 potential corridors, i.e., those where transmission facilities might have entailed severest impacts on the environment, had to be eliminated from consideration before alternative corridors could be delineated. Identified alternative corridor locations were subsequently evaluated to determine \u27most desirable\u27 corridors
