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.
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.
Characteristics of the TijuanaRosarito 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. Área Geoestadística Básica (Basic Geostatistical Area)
Mobile Sources
Mobile Sources
On road
Estimation to be done with two
methodologies:
1. At municipality level using the
government vehicular registers.
2. 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
1. Bus and truck terminals
2. Aircraft (auxiliary power units and
ground support equipment)
3. Locomotives
4. Marine vessels
5. Agricultural and construction
equipment
Used
methodologies:
Emission
factor(Mobile6), models NONROAD and
FAAED
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.

• 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.

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.

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.
