The process of establishing or revising health-based national ambient air quality standards (NAAQS) involves integrating a broad array of scientific information regarding pollutant levels in the environment, population exposures to the pollutant, and health outcomes associated with those exposures into a health risk assessment. Inherent in this process are numerous sources of scientific uncertainty and associated science policy decisions that provide the foundation for public health policy decisions regarding ambient air quality standard-setting. This presentation will discuss potential sources of scientific uncertainty in the air quality standard-setting process and identify potential approaches to addressing these uncertainties. Examples from the health assessments used to support the 2006 particulate matter NAAQS revision, the 2007 proposed Ozone NAAQS review, and other previous NAAQS reviews will be presented to illustrate the influence of these uncertainties and associated science policy decisions in public health policy decision-making.

Learning Objectives:

• Identify key scientific uncertainties associated with the process of setting U.S. national ambient air quality standards.
• List approaches to addressing scientific uncertainty in the air quality standard-setting process.
• Describe how scientific uncertaities have influenced public policy decisions regarding historical reviews of national ambient air quality standards.
