U.S. Environmental Protection Agency Office of Transportation and Air Quality Assessment and Standards Division January 6, 2005 DRAFT MOVES2004 MODEL AND DOCUMENTATION RELEASED FOR PUBLIC REVIEW SYNOPSIS: EPA’s Office of Transportation and Air Quality is pleased to announce the draft release of the first version of the Motor Vehicle Emission Simulator (MOVES), MOVES2004, and supporting documents covering model use, design, and technical inputs. This release initiates a six-month comment period to allow model stakeholders to review and provide comment on any aspect of the model or documentation. MOVES will eventually expand to replace MOBILE6 and NONROAD, the official models for estimating mobile sources emissions; at this time, however, MOVES2004 is being released for review purposes only and does not affect the official status of MOBILE6 or NONROAD. EPA expects to make annual releases of upgraded versions of MOVES, adding pollutants and sources over the next four years and updating underlying data as needed. MOVES2004 provides the basis for these future releases in terms of software design and interface, and by incorporating new methodologies and data for characterizing the on-road vehicle fleet and its activity. The model also estimates energy consumption (total, petroleum-based and fossil-based) and emissions of methane and nitrous oxide for all on-road sources, over the entire U.S. at the county level, from 1999 through 2050. The MOVES2004 package also includes an updated version of Argonne National Laboratories’ GREET model, with a built-in interface, to allow integrated estimation of “well-to-pump” energy and emission effects. The installation ZIP file posted on the MOVES website contains all of the software and underlying data necessary to install and run MOVES2004, including an installation guide (although MS Excel is required to run GREET). This file is large (over 200 MB), so the user should be aware that it may take a long time to download. Upon downloading and unzipping this file, the user should install the model following the step-by-step instructions contained in the installation guide. Once the model is properly installed, the MOVES2004 User Guide should be consulted to get started with model operation.
