This document describes the air quality modeling performed by EPA in support of the final Control of Emissions of Air Pollution from Locomotive Engines and Marine Compression-Ignition Engines Less than 20 Liters per Cylinder (Locomotive/Marine) rule. A national scale air quality modeling analysis was performed to estimate the effect of the rule on future annual fine particulate matter (PM2.5) concentrations, future 8-hour ozone concentrations, and future visibility levels. To estimate the air quality changes expected to result from this rule we used the Community Multiscale Air Quality (CMAQ) model1. The CMAQ model simulates the multiple physical and chemical processes involved in the formation, transport, and destruction of fine particulate matter and ozone. The overall CMAQ modeling platform has been revised from what was used at proposal. A modeling platform is a structured system of connected modeling-related tools and data that provide a consistent and transparent basis for assessing the air quality response to changes in emissions and/or meteorology. A platform typically consists of a specific air quality model, base year and future year baseline emissions estimates, and a set of meteorological model inputs. The final Locomotive/Marine rule modeling analyses were based on a 2002 modeling platform which reflects: (1) an updated version of the CMAQ model, (2) higher resolution PM2.5 modeling, (3) a longer period of ozone modeling, and (4) updated emissions and meteorological data. These updates from the previous 2001 platform will be described in more detail in subsequent sections of this technical support document (TSD).
