AMPO has just completed obtaining information from MPOs and state DOTs in air quality nonattainment and maintenance areas on the status of MOVES implementation. The survey information will be assessed and will be made available through AMPO. Contact Rich Denbow, AMPO's Technical Director, for more information.

The conference includes sessions on sustainability, climate change, bicycle and pedestrian planning, innovative finance, performance measures and much more. For more information, see: AMPO 2011 Annual Meeting.

EPA and DOT Offer Training Course on PM Quantitative Guidance. EPA and DOT recently announced a three-day training course on how to implement EPA's "Transportation Conformity Guidance for Quantitative Hot-spot Analyses in PM2.5 and PM10 Nonattainment and Maintenance Areas." This is a hands-on course targeted to state and local agency staff that are or will be using EPA's MOVES model and air quality dispersion models (AERMOD and CAL3QHCR) for quantitative PM hot-spot analyses. A California course using EMFAC2007 is currently under development. Detailed information about this course, including its content, technical requirements, and a list of upcoming training sessions can be found on EPA's website at: MOVES Project Level Analysis Training.

FHWA Clarifies Eligibility Issues Related to CMAQ Funds and Alternative Fuel Vehicles. FHWA recently clarified an issue related to the application of Federal, government-wide cost principles and the obligation and expenditure of Congestion Mitigation and Air Quality Improvement (CMAQ) funds for alternative fuel vehicles (AFVs). To review the full memo on this topic, see: CMAQ and Federal Cost Principles.

Continuation of the CMAQ 100 percent Federal Share Flexibility. The Energy Independence & Security Act of 2007 amended Title 23 to provide a temporary full Federal share (at 100 percent) for CMAQ projects obligated in Fiscal Years 2008 and 2009. This increased Federal share will continue to apply to CMAQ projects during the most recent SAFETEA-LU extension. In practice, the Federal share flexibility is continued as it was on September 30, 2009, when SAFETEA-LU expired. Any questions related to the CMAQ program should be directed to Mike Koontz at (202)366-2076.

MOVES/EMFAC 24-month Grace Period for Hot-Spot Analyses Started December 20, 2010. To access the Federal Register notice, guidance documents, and fact sheets, go to: EPA's Project Level Conformity.

MOVES2010's 24-Month Grace Period for Regional Conformity Analysis Started on March 2, 2010. For more information, see The Federal Register notice, EPA's guidance, and the MOVES website.
