  2. Review of Emission Inventories

  3. El Paso NOx Emissions (tons/year)

  4. El Paso VOC Emissions (tons/year)

  5. 1996 Regional Emissions

  6. Emission Inventory Improvements for El Paso

  7. Development of Onroad Emissions Based on the transportation network used by the El Paso MPO

  8. NOx Emissions from Major Nonroad Mobile Sources in El Paso

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

  10. Example: Method of Estimating Emissions from Locomotives • EMISSION FACTORS: derived from EPA Emission Factors for Locomotives (EPA-420-F-09-025, 2009) • ACTIVITY DATA: Gross Ton-miles (GTM) from line haul locomotives operating in El Paso in 2005 and 2008 (Union Pacific (UP) and Burlington-Northern Santa Fe (BNSF)); Number of switch locomotives operated in El Paso in 2005 and 2008 (UP and BNSF)

  11. Summary • Reviewed and documented existing El Paso emission sources for significant ozone precursors • Identified 6 emission sources for improvement in the EI database • Provided methodologies to improve the data quality • Developed work plan for further data collection or quantification (not discussed in this presentation)
