The Southern Appalachian Mountain Initiative (SAMI) is a consortium of eight Southeastern states, including North Carolina, and several federal agencies. It is now beginning to publish its research, more than a decade in the making, and will likely help to shape the debate on air quality for years. State policymakers should be cautious in interpreting SAMI data and analyses, however, due to troubling signs that it may not be looking at both sides of the regulatory equation.
