This report was prepared for the EPA and the Dept. of Energy. The findings of analyses of alternative new source performance standards are presented herein. All the assumptions and scenario specifications employed for the analyses reported in Still Further Analyses of Alternative NSP Standards for New Coal-Fired Powerplants were employed except: some of the scrubber cost estimates were revised by EPA; EPA developed several new specifications of alternative standards; and a few forecasts were made to reflect the effect of alternative standards on emissions after all existing coal-fired capacity is retired. EPA decided to include considerations of dry scrubbing in this set of analyses. In previous analyses, all the cost estimates were developed for 'wet scrubbing'. EPA requested that 14 alternative standards be assessed. These alternatives were specified in terms of: alternative ceilings; alternative scrubber costs; and alternative levels of partial or variable scrubbing for lower sulfur coals.
