2. El Paso Rider 8 Program • A Texas program developed to assist areas stay in air quality attainment for ozone in accordance with the State Implementation Plan (SIP) • Joint effort by EPMPO and UTEP • Tasks accomplished: • Developed a conceptual ozone model to understand the nature of ozone pollution in the Paso del Norte region • Developed control strategies for ozone reduction in El Paso • Developed a website for the El Paso RIDER 8 program

3. Recent Progress • Involve and educate the public to promote awareness of air quality • Develop local ozone control strategies • Perform additional ambient monitoring at selected locations • Quantify emissions for selected emission inventory improvements • Perform air quality modeling for Texas SIP

13. Quantification of Improvements in Emission Inventories

14. Identified Emission Inventory Improvement Targets for El Paso • Light duty and heavy duty vehicles at the El Paso-Juarez international ports of entry; • Aircraft, auxiliary power units, and airport ground support equipment; • Locomotives; • Tactical operations at Ft Bliss Military Reservation; and • Extended idling of heavy duty diesel vehicles at truck stops and rest areas

15. Emissions from the International Ports of Entry • Conducted emission estimation for the BOTA and scale it for the other 2 bridges in El Paso (excluding the Stanton Street Bridge) • Estimated traffic volume and profile using 2005 traffic counts at the BOTA and 2006 CBP reported data • Estimated queue length and wait time at TBOA using MPO’s BQAT software • Estimated emissions using EPA’s MOVES software

16. Four International Ports of Entry

17. Emission Estimation for Other Sources • ELP Airport Emissions • FAA’s EDMS Model • Fleet mix and airport operations from ELP • Locomotive Emissions • Data from Union Pacific (UP) and Burlington Northern Santa-Fe (BNSF) • Ft. Bliss Tactical Operations • Data from Ft. Bliss • Truck Stop Emissions • Survey data • EPA’s MOVES emission model

18. Emissions Inventory Improvements • Daily Emissions at the POEs (in tons/day)

19. ELP Airport Emissions (in tons/year)

20. Emissions from the International Ports of Entry • Locomotive Emissions (in tons/year)

21. Ft. Bliss Tactical Operations (in tons/year)

22. Truck Stops Emissions (In progress)

23. Summary of Emissions Inventory Improvements • Significant emissions from the POEs • Significant emissions form ELP airport • Moderate emissions from locomotives and rail yards • Insignificant emissions from truck stops • Uncertainties in Ft. Bliss tactical emissions

24. Ozone Modeling

25. Progress in Ozone Modeling • UTEP performed WRF meteorology simulation and a screening CAMx run • Environ performed 2 CAMx sensitivity runs • UTEP is in the progress to summarize the study • UTEP will conduct additional studies to include the recently developed improved emission inventory
