Abstract
The document describes the air quality modeling performed by EPA in support of the proposed Locomotive/Marine rule. A national scale air quality modeling analysis was performed to estimate the effect of the proposed rule on future year: annual PM(sub 2.5) concentrations, daily maximum 8-hour ozone concentrations, and visibility. To model the air quality benefits of this rule the authors used the Community Multiscale Air Quality (CMAQ)(sup 1) model. CMAQ simulates the numerous physical and chemical processes involved in the formation, transport, and destruction of ozone and particulate matter. In addition to the CMAQ model, the modeling platform includes the emissions, meteorology, and initial and boundary condition data which are inputs to this model.
