OFR-59-88 The Potential Impact Of Acid Rain Legislation On The Domestic Aluminum Smelting Industry: Methodology And Documentation ? 1. Introduction - 1.1 Purpose

For electric utilities serving the aluminum smelter industry in the United States, sulfur oxide (SOx) abatement legislation could bring about increases in the costs of generating electricity. This paper documents the method and assumptions used in estimating these increases, and the contains the results of the estimation. 1.2 SMELTER INFORMATION The smelters used in this study were identified by the Bureau of Mines (BOM) and are listed in Table 1.1. Also included in Table 1.1 are the electric utilities that serve these smelters. Compliance costs were estimated for these utilities. Some of the utilities are unique in the way that the information is handled or in the way the utility is operated; these are discussed below. 1.2.1 Big Rivers and Associated Co-ops, Data for Big Rivers and Associated Co-ops were gathered by George Mason University (GMU) students for BON and are included in this study.
