The users manual describes a computerized system--consisting of a number of integrated programs, models, and data bases--that has been developed to compare the costs of power plant strategies designed to meet clean air regulations. It describes the data bases, programs, and procedures and requirements that are necessary for data base access and program execution. The power plant data base contains actual and projected information for all U.S. fossil-fuel power plants. A scrubbing cost model allows cost comparisons between any two of five compliance strategies: limestone scrubbing with sludge waste disposal, limestone scrubbing with gypsum production, sodium sulfite scrubbing with sulfur production, magnesia scrubbing with sulfuric acid production, and the use of clean fuel with no scrubbing. For salable flue gas desulfurization (FGD) byproducts, cost comparisons include potential marketing revenues. The sulfur and sulfuric acid data base includes actual and projected information for all U.S. sulfur-burning acid plants. The transportation data base contains legal rail mileages between all rail rate basing points in the 37 Eastern States (Docket 28300) and also contains location-related data for every named U.S. location. Each data base and program can generally be used independently of the other parts of the system.
