On 4 January 1978, the U.S. Environmental Protection Agency (EPA) promulgated a final rule for the control of sulfur oxide (SOx) emissions at existing nonferrous smelters in the State of Arizona, imposing a maximum emission limitation for each smelter as a 6-hour running mean. Emission limits, determined from a 1973-74 data base, were set by proportionally 'rolling back' the 24-hourly average smelter emissions, estimated by sulfur balance or other methods, for the day on which the maximum 3-hour-average ambient concentration of sulfur dioxide was observed. In response to the EPA rule, the State of Arizona has proposed an alternative approach to calculating copper smelter emission limits based on a statistical model. This new approach is known as 'multipoint rollback' and is based upon rollback of the entire distribution of emissions at the smelter. EPA's Region IX Office determined the need for technical assistance in evaluating Arizona's proposed method, and contracted with SRI International (SRI) for an objective evaluation.
