Cost benefit analysis
The Regional Haze rule is designed to enhance and protect visibility at large national parks and wilderness areas. There are 156 of these nationwide and they are called Mandatory Class I Federal Areas.
The Executive Summary of the RIA provides and overview of the scope, methodology, findings, limitations and conclusions of the Regional Haze RIA. Chapter 1 provides a brief description of the nature of the rule, refinements to the previous economic analysis, present analytical approach and remaining caveats and limitations. Chapter 2 describes the Statutory Authority for the Regional Haze rule as well as pertinent Executive Orders and Congressional Mandates related to the rule-making and analysis. Chapter 3 describes the illustrative progress goals and control strategies. Chapter 4 explains the concepts of benchmark and baseline emissions and air quality. Chapter 5 describes control measures, while Chapter 6 addresses emission reductions, air quality, visibility, and cost impacts, including the BART element of the rule. Chapter 7 estimates the administrative burden and costs associated with the final Regional Haze rule and Chapter 8 contains an assessment of the potential economic imp act of the rule as well as ways to avert or mitigate some impacts. Chapter 9 describes the underlying scientific physical and economic information used to assess benefits, the resulting benefit estimates, and plausibility checks for the estimated benefits. Chapter 10 contains a benfit-cost analysis for four uniform national progress goals as well as a situation where illustrative progress goals can vary across the geographic regions of the country (e.g. midwest/northeast, southeast, south central, Rocky Mountain, west, and northwest).
