Announcements and Recent Events

EPA Releases Revised MOVES2010a Installation Suite. U.S. EPA has revised the MOVES 2010a Installation Suite to improve model run time and to make it easier to install MOVES. The revised installation suite includes a number of improvements and also upgrades the MOVES default database. No changes were made to calculations in the MOVES code or to the content of the default database. This revision is not a new emissions model for the purposes of conformity or SIP development nor does it change the grace period which ends on March 2, 2012 before use of the model is required. The suite is available at: EPA's website.

Next MOVES Model User Group for MPOs Web Conference October 14, 2010. FHWA will be offering a web conference on October 14, 2010 for MOVES Model Users from 1:00-2:30 pm eastern time. The web conference will cover the purpose of the User Group, EPA/FHWA MOVES model training, a presentation on TDM2MOVES by Kip Billings from Wasatch Front Regional Council in Utah, spatial allocations of starts in the MOVES model, and an open discussion. Because of the limited number of phone lines, please register for the web conference early. Previous web conference presentations are available on AMPO's website. For more information on the MOVES model user group, contact Bob O'Loughlin.


Continuation of the CMAQ 100 percent Federal Share Flexibility and FY 2010 Supplementary Tables are Available. 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.

In addition, FY 2010 Supplementary Tables - Apportionments Pursuant to the Surface Transportation Extension Act of 2010 - were released on May 28th. Information on CMAQ funds authorized for FY2010 and apportioned to the States can be found in these tables. See

Any questions related to the CMAQ program should be directed to Mike Koontz at (202)366-2076 or

2006 PM2.5 Nonattainment Areas Must Demonstrate Conformity by December 14, 2010. In 2006, EPA promulgated a new 24-hr PM2.5 standard. The effective date of designations for that standard was December 14, 2009; thereby making conformity required in those newly-designated areas by December 14, 2010. There is no lapse grace period for newly-designated areas. EPA published the Transportation Conformity Rule PM2.5 and PM10 Amendments in the Federal Register on March 24, 2010. The rule includes requirements for demonstrating conformity in 2006 PM2.5 areas, updates the baseline year to 2008 for interim tests in 2006 PM2.5 nonattainment and maintenance areas, discusses which budgets should be used in PM10 areas to demonstrate conformity now that the PM10 annual standard has been revoked, and clarifies that federally funded or approved highway and transit projects in PM2.5, PM10 and CO nonattainment and maintenance areas must not delay timely attainment or achievement of other interim milestones. The rule and additional information can be found at:

MOVES2010's 24-Month Grace Period for Regional Conformity Analysis Started on March 2, 2010. The Federal Register notice includes EPA's announcement of the approval and availability of MOVES2010 for SIPs and regional emissions analyses in all states except California ( The notice also starts the two-year transportation conformity grace period that ends on March 2, 2012, after which MOVES2010 is required to be used for new regional emissions analysis for transportation conformity. EPA did not approve the use of MOVES2010 for project-level transportation conformity hot-spot analyses, which will be addressed in a future Federal Register notice. Guidance on implementing MOVES2010 for SIP development and conformity purposes can be found at: The MOVES2010 model and supporting materials can be found on the MOVES website:
