This document describes the air quality modeling performed by EPA in support or air quality and deposition assessments related source sector groups. A national scale air quality modeling analysis was performed to estimate the impact of current and future year sector emissions on annual and 24-hour PM2.5 concentrations, 8-hr maximum ozone, as well as visibility impairment. Air quality benefits are estimated with the Comprehensive Air Quality Model with Extensions (CAMx) model. CAMx simulates the numerous physical and chemical processes involved in the formation, transport, and destruction of ozone, particulate matter and air toxics. In addition to the CAMx model, the modeling platform includes the emissions, meteorology, and initial and boundary condition data which are inputs to this model. It is important to note that the inventories used in the air quality modeling may be different than a final sector inventory presented in a Regulatory Impact Analyses.
