ESTIMATION OF REAL WORLD EMISSIONS FROM HIGHWAY VEHICLES The U.S. Environmental Protection Agency wishes to provide financial assistance to non-profit research organizations to promote development of accurate and affordable methodologies for estimation of real world emissions from highway vehicles. The pollutants of interest are (but are not limited to) volatile organic compounds (VOCs), nitrogen oxides (NOx), carbon monoxide (CO), particulate [size fractions of 2.5 and 10 micrometers, generally referred to as PM2.5 and PM10 respectively], toxics/Hazardous Air Pollutants (HAPs), and greenhouse gases (GHGs). Principal areas of interest are 1) improved emission inventory modeling techniques within the Mobile Emissions Assessment System for Urban and Regional Evaluation (MEASURE) framework; 2) development of gridded hourly emission factors with specified uncertainty reductions due to the introduction of alternative fuel vehicles; 3) development of gridded hourly activity factors with specified uncertainty; 4) estimated emissions reductions due to the introduction of alternate fuel vehicles; 5) improved mobile source generated fine PM and fugitive dust modeling; 6) estimated/ improved toxic/HAPs emissions modeling; 7) estimated emissions reductions due to control program effectiveness; and 8) validation of emission estimation methods developed by this research. EPA expects to award up to $100,000 to the successful applicant in fiscal year 2000. Based on the success of the research and availability of additional funding, it is possible that total funding in the amount of $2,000,000 may be awarded for this assistance area over a five year period. Multiple awards may be given in specific work areas if applicants with strengths in all areas are not identified in the solicitation process. Such multiple awards would reduce the amounts awarded to a single recipient. In order to qualify for the award of this assistance program, applicants must first submit a pre-application package in response to a Request for Application (RFA) which will be issued by EPA within the next sixty days. Qualified non-profit research organizations who wish to receive a copy of the RFA may submit a request, citing number APPCD 2000-1, no later than October 15, 1999, to M.P. Huneycutt, USEPA, Mail Drop 49, Research Triangle Park, NC 27711 or to the email address shown below. Oral requests cannot be honored. WEB: Not Applicable. No RFP available., www.epa.gov/appcdwww/crb/ecpd/mobile.htm. E-MAIL: Not applicable. No contract involved., huneycutt.malcolm@epa.gov. Posted 09/23/99 (W-SN383668).
