  1. TIJUANA AND PLAYAS DE ROSARITO EMISSIONS INVENTORY February 18th 2010

  2. Emissions Inventory Plan

  3. QAPP • QAPP was conditionally approved on October 21st 2009. • Comments were received on November 11th 2009. • Technical corrections were made and QAPP was delivered on December 4th 2009. • Committee roles were integrated on January 17th 2010.

  4. Objective To have an emissions to the atmosphere inventory for Tijuana-Rosarito in order to identify the main sources of pollutants, the quantity of emitted pollutants by type, where and when (season of the year) they are emitted with the purpose to develop the “PROAIRE” (Air quality program) in the region.

  5. Characteristics of the Tijuana-Rosarito emissions inventory • Base year: 2005 • Coverage: Tijuana and Playas de Rosarito municipalities. • Evaluated sources: Stationary, mobile (on road and non road), area and biogenical. • Pollutants to be estimated: CO, CH4, SOx, NOx, PM10, PM2.5, VOCs, HC, NH3. • Time representation: Seasons. • Geographical representation: • Stationary sources: Point and AGEBs. • Mobile sources: At roadway level and AGEBs. • Area sources: AGEBs. • Biogenical sources: At land use level and AGEBs. AGEB. ÁreaGeoestadísticaBásica (Basic Geostatistical Area)

  6. Mobile Sources

  7. Mobile Sources On road Estimation to be done with two methodologies: • At municipality level using the government vehicular registers. • At roadway level, using the transport model. For this methodology, fieldwork was done in order to calibrate the model. The Mobile6 model will be used to obtain the emission factor required for both methodologies. This model will be suitable for the study region, because of the use of the information collected in field. Non road • Bus and truck terminals • Aircraft (auxiliary power units and ground support equipment) • Locomotives • Marine vessels • Agricultural and construction equipment • Used methodologies: Emission factor(Mobile6), models NONROAD and FAAED

  8. On road mobile sources • a) Selection of representative roadways • b) Vehicle counting. Counting systems are used in order to know the quantity of vehicles circulating in different type of roadways. • c) Travels in different roadways in order to know the speed in such roadways. • d) Videotaping is made in order to know the vehicle fleet composition; and • e) Surveys are made in order to identify the kilometers traveled by the vehicle type.

  9. On road mobile Sources Tijuana Rosarito • Roadway selection

  10. On road mobile Sources • Roadway selection Tijuana Freeway Arterial Local

  11. On road mobile Sources • Roadway selection Rosarito Freeway Arterial Local

  12. On road mobile Sources • Roadway selection. Tijuana

  13. On road mobile Sources • Roadway selection. Playas de Rosarito

  14. On road mobile Sources Vehicle counting • Counting devices were installed for 62 points in 31 roadways for Tijuana and Playas de Rosarito, registering data for each roadway at least for 24 hours, considering both directions of the roadway.

  15. On road mobile Sources Circulation Speed with Scanner OBDII • 31 roadways were selected for travels along them, in order to identify the vehicles speed. • 118 travels • Time of the travel depends on length of the roadway and traffic load. • Travels lasts between 4 and 25 minutes by roadway in Tijuana and between 2 and 13 minutes in Playas de Rosarito.

  16. On road mobile Sources Vehicular classificationVideotaping 114 Videotapes were done, lasting 20 minutes each. Videotapes were made in the 31 selected roadways in Tijuana-Playas de Rosarito

  17. On road mobile Sources • Vehicular classification

  18. On road mobile Sources • Identified Vehicular fleet (up to now)

  19. On road mobile Sources Surveys • Total of surveys: 1200. • 42 survey points in Tijuana and 8 in Playas de Rosarito; Nov 9th to 17th, 2009. • Sites: gas stations, bus stops, public parking lots and taxi base stations.

  20. On road mobile Sources Progress in surveys evaluation for traveled kilometers and origin-destination. Data Base

  21. On road mobile Sources Transport Model TRANUS.

  22. Non Road Mobile Sources • The request and management of the information is currently in development. • Up to now, information of marine vessels has been received.

  23. Area Sources

  24. Area Sources • 8. Structure fires • 9. Sanitary landfill and open-air disposal of waste • 10. Waste water treatment • Dust from unpaved roads • Dust from paved roads • Construction Activities • Aeolia erosion. Erosive • Resurfacing of architectural surfaces • Asphalting • Dry cleaning • Cleaning and degreasing • Auto paint (body painting) • Traffic Paint • Commercial solvent use • Resurfacing industrial surfaces • Graphic Arts • Gasoline distribution • LP gas distribution • Massive fuel storage • Domestic ammonia emissions (NH3) • Raw sewage and waste water (NH3) • Animal waste (NH3) • Farming • Agricultural crops • Agricultural pesticides • Cattle feedlots • Fertilizer use (NH3) • Charbroiling (street vendors) • Area sources identification. • Information request and management. • Emissions estimation from surveys, mechanistic models, emission factors, energy and material balance. Sources to be estimated: • Combustion of industrial fuel • Commercial/institutional combustion (restaurants, tortilla shops, bakeries, charcoal grilled meat vendors, hotels, itinerant food stands) • Household combustion • Border Crossings • Brick Kilns • Agricultural burns • Forest fires

  25. Area Sources Main commercial and services business identified in Tijuana-Playas de Rosarito area.

  26. Area Sources Surveys applied • 742 surveys totally applied • 10% data capture

  27. Stationery Sources

  28. Stationery Sources • Information request and management. • Emission estimation by emission factor (AP-42) and by energy and material balance. • Emissions at municipality level, jurisdiction, industrial sector, industrial facilities and type of fuel.

  29. Stationery Sources • There are 333 regulated facilities. • 82% State and 18 % Federal.

  30. Stationery Sources Technical information is being evaluated, according with that reported by the state industrial facilities in their COA’s (Annual Operation Report). 59 facilities from 274 have been revised and the emissions estimations have started. From the remaining 215 facilities, only 81 (38%) have reported information about fuel consumption and currently this information is being validated. From the 81 facilities reporting fuel consumption, 41 have inconsistencies.
