EPA-NAAQS

　　The Menu of Control Measures (MCM), complied by the State and Local Programs Group within U.S. EPA's Office of Air Quality Planning and Standards, was developed to provide information useful in the development of local emission reduction and NAAQS SIP scenarios, and identifying and evaluating potential control measures. This informational document is intended to provide a broad, though not comprehensive, listing of potential emissions reduction measures for direct PM 2.5 and precursors of ozone and PM 2.5 . Concerning mobile sources, we encourage State air planning agencies to consider these control measures when they do an initial screening step to identify the sectors that warrant more detailed analysis as part of their control strategy preparation for nonattainment ozone or PM SIPs. It is critical that this information be used only as a screening step and that final SIPs should be based on mobile source model runs for States' specific geographic areas following guidance from EPA's Office of Transportation and Air Quality (OTAQ).
