  1. 2008 Emissions Inventory for the Municipality of Juárez, Chihuahua, Mexico Meeting of the Joint Advisory Committee for the Improvement of Air Quality – Paso Del Norte January 17, 2013 Marty Wolf – Eastern Research Group, Inc. Arturo Woocay, Ph.D. Jose Maria Mares Vazquez, Ph.D.

  2. Inventory Objective & Scope • Objective – Develop 2008 base year emissions inventory for ozone modeling • Scope • Pollutants: NOx, SO2, VOC, CO, PM10, PM2.5 • Source types: point, area, on-road motor vehicle, nonroad mobile, biogenic • Inventory domain: Municipality of Juárez • Spatial resolution: Municipality-level

  3. Inventory Objective with Contractors Working with Mexico-based contractors. Developing skills and capacity for Mexico’s engineers to develop emissions inventories. Importance of having skilled and experienced engineers working in the field and teaching skills to students attending the local universities.

  4. Phase I Completed in August 2011 Includes area, on-road, nonroad, and biogenic sources Point sources not included – focus of Phase II Area sources (fuel combustion, evaporative, fires, other) On-road motor vehicles Nonroad mobile sources (aircrafts, locomotives, and construction and agricultural equipment) Biogenic sources (vegetation VOC and soil NOx)

  5. Phase II(currently underway) • 2008 point source emissions inventory provided by SEMARNAT with 182 point sources • Focus will be on QA of SEMARNAT inventory • Geographic coordinates check for 45 point sources • QA of COA data • Largest emitters • Pollutant inconsistencies • Comparison of input material consumption with reported emissions • Stack parameters

  6. Phase II – Point Source QA • EPA and TCEQ require contractors to QA data • Inventory development is an iterative process in which inventory data is constantly reviewed and improved

  7. Phase II – Geographic Coordinate Check

  8. Phase II – QA of COA data • Largest emitters • Facilities with “questionable” data • No reported emissions • Controlled emissions are greater than uncontrolled emissions • Reported paint, solvent, or other evaporative input materials, but no process VOC emissions • Reported natural gas fuel use, but only reported PM emissions without NOx or CO emissions • Reported natural gas fuel use, but reported high PM combustion emissions
