This study attempts to provide information for South Korea’s domestic ozone control strategy development. To achieve the study goal, we reviewed several aspects of ground level ozone management in US. First, we summarized characteristics of ground level ozone. In our summary, we emphasized currently known physico-chemical nature of ozone is the fact that ozone being a product of two major precursors - NOx and VOCs - as well as processes that determine source-receptor relationships. Second, we described an overview of current ozone management in US. We highlighted major goals, processes, and tools in the current US ozone management system. Third, we examined history of the US ozone management system including advances of ozone science from 1940s to present. We examined series of historical events and explained how those events led to processes and tools used in the current US ozone management. Special emphases were placed on relationships between various ozone control policies and ozone science advances in US over time. Last, we reviewed lessons learned from past US ozone management practices and suggest what can be adopted and avoided for South Korea’s future ozone control strategy
