Date:		February 15, 2012
Subject:	Stakeholder call about MOVES Transition for Regional Conformity Analyses 
From:	Meg Patulski, State Measures and Transportation Planning Center, OTAQ
To:		Docket EPA-HQ-OAR-2011-0393

	On March 7, 2011, a conference call was held to discuss stakeholder concerns regarding the transition to using MOVES for regional conformity analyses.  EPA's Office of Transportation and Air Quality hosted the call, and the following other agencies were represented on the conference call:  
      * State air agencies from:  Connecticut, Massachusetts, New Hampshire, Rhode Island, New York, New Jersey, Maryland, Delaware, Pennsylvania, Virginia, North Carolina, Tennessee,  Florida, Kentucky, South Carolina, Michigan, Wisconsin, Indiana, Alabama, Arkansas, Oklahoma, Missouri, Colorado, Arizona, Nevada, Idaho, and Alaska
      * Local air agencies from:  Chattanooga, TN; Knoxville, TN; Nashville, TN; Jacksonville, FL; Dayton, OH; and Washoe County, NV
      * National Association of Clean Air Agencies (NACAA)
These agencies requested additional transition time for using MOVES in regional conformity analyses and any necessary revisions to state implementation plan (SIP) motor vehicle emissions budgets.  State and local agencies were concerned about the significant software, operational and technical differences between MOVES and the previous emissions model, MOBILE.  
      EPA expressed its intentions to proceed with a rulemaking to extend the MOVES2010 regional conformity analysis grace period.  All agencies strongly supported EPA's decision to proceed with this rulemaking.
