Mobile Sources Technical Review Subcommittee (MSTRS) of the CAAAC

The Subcommittee provides the Clean Air Act Advisory Committee (CAAAC) with independent advice, counsel and recommendations on the scientific and technical aspects of programs related to mobile source air pollution and motor fuels. Through its various workgroups, the MSTRS addresses a wide range of developments, issues and research areas such as emissions modeling, air toxics, innovative and incentive based transportation policies, on-board diagnostics, heavy-duty engines and reformulated gasoline.

The MSTRS is composed of approximately 30 technical experts drawn from a wide range of stakeholder organizations. Included on the roster are individuals from the automotive industry (vehicles, engines and components), energy companies, academia, public interest groups, and state/regional/local governments. As a result of the workgroup structure employed to address specific areas, almost 60 people are involved in the work of this subcommittee.

Meetings of the full subcommittee are held biannually. Workgroups may meet several times per year in addition to the full subcommittee meetings. Since its formation in 1996, the MSTRS has presented several major reports and recommendations to the CAAAC which, in turn, have been forwarded to the Agency for its consideration and action.
