These costs were developed to reflect the conventional use of technologies in this industry. Several unit operation/unit process configurations have been analyzed for the cost of application of technologies and to select the best practicable control technology (BPT) and best applicable technology (BAT) level of treatment. The detailed presentation of the applicable treatment technologies, cost methodology, and cost data are available in the literature.1-4 Specifically the U.S. EPA Report W-83-13, "Cost Effectiveness Analysis of Effluent Guidelines and Standards for the Aluminum Forming Category" reports the results of a cost-effectiveness (CE) analysis of alternative water pollution control technologies for the aluminum forming category.4 The primary cost of interest in the U.S. EPA report is the total annualized cost in complying with the regulations incurred by industry. The 1983 costs can be easily updated to the current cost,1213 or any future costs using the cost indexes announced periodically by the U.S. Army Corps of Engineers (U.S. ACE)14 or Engineering News Record of McGraw-Hill Book Company, NY.
