Volume 2 contains a discussion of US coal supplies within a reasonable distance, their cost, and transportation method, depending somewhat on the mine location. Also, included are technical and environmental evaluations and comparison with those of a coal-fired plant equipped with a scrubber. Site selection considerations, baseline ecology, permit applications, emissions and air and water pollution control, air and water quality impacts, socio-economic factors, and engineering cost data. The potential for improvements of the combined-cycle plant is considered: increase in temperature on efficiency, advanced gas turbine cycle, acid gas removal (Rectisol II).
