Treatment and disposal alternatives and costs for hazardous wastes from the organic chemicals, inorganic chemicals, and electroplating and metal finishing industries are evaluated. The 16 treatment and 5 disposal technologies were based on applicability to the industry categories, availability of cost and performance data, and effectiveness in reducing or eliminating hazardous waste constituents. Costs were aggregated at the technology level and entered in computer-linked models at the unit cost or component level. Volume II contains applicable portions of the Resource Conservation and Recovery Act, capital unit cost and operation/maintenance cost data files, curve fitting for cost files, module descriptions, and system variable equations. Volume II is intended for those desiring the supporting data for Volume I.
