FACA MOVES Model Review Workgroup (updated 4/28/09 pm) Matthew Barth Professor and Director College of Engineering-Center for Environmental Research and Technology University of California-Riverside EPA-420-A-09-003 ------- MOVES Review Workgroup Objectives To evaluate and provide recommendations on the inputs proposed for use in MOVES... - emission rates - fleet & activity - fuel and other adjustments To evaluate MOVES input and output structures and their usefulness in meeting the needs of modelers developing SIPs and transportation conformity programs Under FACA structure, workgroup recommendations are made to the MSTRS 2 ------- MOVES Workgroup Membership Chairs: - John Koupal, EPA - Matt Barth, UC Riverside Industry: - Auto Alliance, AIAM, EMA, API, CRC Environmental Groups: - NRDC, Environmental Defense State and Local Government: - NACAA, AASHTO, GARB Federal Government: - EPA, FHWA Academia: - UC Riverside, Georgia Tech, NC State, Cornell ------- MOVES Workgroup Process EPA presents MOVES modeling materials at meetings Meeting notes are taken and distributed Workgroup members poll their membership and provide feedback comments Comments are compiled, summarized, and distributed Workgroup discusses comments at next meeting with the goal of developing consensus recommendations to be forwarded to MSTRS Workgroup also reviews draft MOVES reports as they become available ------- 2007-2009 Meeting Topics Fleet & Activity, Light Duty HC/CO/NOx emission rates Light Duty PM rates & Kansas City Study Evaporative emissions Fuel Effects Inspection/Maintenance Heavy Duty emission rates and Temperature Effects Fleet & Activity Update Tier 2 Emission Rates, LD PM & High VSP bins E10 & E85 effects, Air Toxics Heavy Duty Emission Rates Draft MOVES2009 & Project Level Manager ------- MOVES is largely shaped by data collected since the release of MOBILE6 Activity - in-use vehicle trip patterns - VIUS2002 Light-Duty Vehicles - thousands of in-use vehicles from I/M programs - Kansas City gasoline PM study - remote sensing data - in-use certification verification data Heavy-Duty Vehicles - 100 in-use vehicles (E-55 plus) - MOBILE6 based on engine certification data ------- Workgroup Comments: Workgroup discussions with EPA have been very open and informative. MOVES depends heavily on data; continuing data collection is essential Model validation is a higher priority than new features ------- Workgroup Recommendations: Data Collection Priorities for next phase of MOVES development/maintenance should be based on sensitivity analyses. EPA team should develop a "data collection plan" that would fill data holes and provides data into the future for maintenance EPA should consider some type of periodic surveillance data collection program, in addition to relying on I/M data sets, data from rule making projects, programs such as KC project, PEMS, etc. EPA should continue to be aggressive in obtaining data from similar or related data collection programs (state DOTs, California Air Resources Board, CRC) 8 ------- Workgroup Recommendations Validation EPA should develop a validation plan: - Potentially funded and/or carried out by other entities - Include comparisons to • MOBILE6 and EMFAC • remote sensing data • tunnel studies - Include intermediate validation of model subparts ------- Workgroup Recommendations: Future updates Workgroup has concerns on how EPA is going to update MOVES in the future: - need to update both emissions and fleet/activity inputs - need to assure data is available - Updates on a regular/ irregular basis? • perhaps consider regular periodic version release: MOVE2007, MOVES2008, etc. 10 ------- Workgroup Recommendations: Other • Significant outreach should occur with transportation community on interfacing MOVES with transportation data and models - FHWA has begun to address - Workshops, trainings and other communications need to continue • Ensure that future funding stream is available for MOVES development and maintenance 11 ------- |
