MOVES Review Work Group, Final Report to the Clean Air Act Advisory Committee, February 2022

Approved for submittal to EPA by the Clean Air Act Advisory Committee, February 2022.

The MOVES (Motor Vehicle Emission Simulator) Review Work Group was formed by the Mobile Sources Technical Review Subcommittee (MSTRS) of the Clean Air Act Advisory Committee (CAAAC) in September 2016 to provide input to EPA on MOVES development. Members of the workgroup represented a spectrum of stakeholders, including vehicle and engine manufacturers, fuel producers, state and local emission modelers, academic researchers, environmental advocates, and affected federal agencies.

Over the course of five years, the MOVES Review Work Group met 13 times to review and discuss draft information on MOVES algorithms, data inputs and other features. Most presentations were given by EPA, but work group members also shared information, via presentations and discussions, with the work group. Notes from work group meetings were distributed to work group members and comments on meeting materials were compiled. The work group provided status presentations to the MSTRS at public meetings in October 2016, May 2017, May 2018, August 2019, and October 2020. As part of the May 2017 and May 2018 MSTRS presentations, the work group compiled and shared a set of interim recommendations. The work group chairs provided a final presentation to the MSTRS in October 2021 and to the CAAAC in December 2021 that summarizes the information in this report. In February 2022 the CAAAC voted to adopt the report and present it to EPA.
