production and pollution-control technologies are important considerations. The committee also recognizes that future developments in other pollution laws and regulations could have a substantial influence on the effects of NSR changes. Thus, the committee strove to consider the plausibility, significance, and interactions of those other relevant requirements.

To establish a background and context for the committee’s technical and scientific analysis, Chapter 2 provides a regulatory overview of the NSR programs in the context of the CAA. It also describes and discusses the NSR changes that are the subject of the committee’s evaluation. Chapter 3 considers emission sources subject to NSR and technology options available for their control. Chapter 4 continues discussions begun in the committee’s interim report on an analytic framework for assessing effects of NSR changes. Chapter 5 discusses econometrics as a way to measure effects of the NSR changes. Chapter 6 assesses the potential efficiency, technology, and emission implications of the NSR changes on electricity-generating facilities. Chapter 7 examines contributions that emission sources subject to NSR may make to ambient air quality and relationships between specific air pollutants and health effects. Chapter 8 presents the committee’s overall conclusions and suggests the kinds of analyses that are needed to address the information needs identified in this report. Terms and abbreviations used in this report are defined in a section after the references.
