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 17, 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 (Lee Cook, Rudy Kapichak, Meg Patulski, and Astrid Larsen) hosted the call with Robert Yuhnke, an attorney and liaison for several environmental stakeholders.  EPA expressed its intentions to proceed with a rulemaking to extend the MOVES2010 regional conformity analysis grace period because several state and local transportation and air quality agencies had requested additional transition time for using MOVES for regional conformity analyses.  State and local agencies were concerned about the significant software, operational and technical differences between MOVES and the previous emissions model, MOBILE.  Mr. Yuhnke expressed concerns about extending the grace period in nonattainment areas that had not yet attained the applicable NAAQS.
