 Abstract This project summarizes and evaluates the activities of the Ozone Transport Assessment Group (OTAG), which was organized to address the problem of the long-range transport of tropospheric ozone (O3) and its precursors across the eastern United States. This air quality management problem is complex, involving multiple sources and receptors, multiple stakeholders with different interests, and multiple jurisdictions of political control. The problem can be briefly summarized as follows: Human activity in one jurisdiction generates emissions of nitrogen oxides (NOX) and volatile organic compounds (VOCs) into the atmosphere. These pollutants are carried by winds to other locations. As these pollutants are carried downwind, they react with each other in a complex, non-linear system of chemical reactions to form ozone and other oxidants. Ozone and the other photochemically-formed oxidants cause damage to human health, vegetation, and man-made materials in some other jurisdiction 100's to 1000's of kilometers away from where the emissions occurred. Throughout this essay, we will refer to the long-range nature of this environmental problem as the regionality of ozone. Based on our study of OTAG's efforts to address the regionality of ozone, we have identified lessons that may be applied in the future to manage other regional air quality problems, or other multi-jurisdictional and multi-stakeholder environmental problems.
