Ciudad Jurez Area Sources Emissions Inventory

1
Ciudad Juárez Area Sources Emissions Inventory

• Project Kick-off Meeting
• Part I
• Project Overview
• Ciudad Juárez, Chihuahua, Mexico
• January 29, 2003

2
Inventory Objectives

• Update previous emissions inventory to 2002
• Focus on area sources
• Increase knowledge of smaller industrial sources
• Conduct surveys to support bottom up methods

3
Inventory Scope

• Base year 2002 (may use previous year projected
  forward to 2002)
• Geographic area Cd. Juárez and surrounding
  municipality
• Pollutants PM10, PM2.5, VOC, NOx, SO2, CO, NH3
• Temporal resolution Annual (tons/year), ozone
  day (tons/day)
• Spatial resolution Actual (preferred), areawide
  (as necessary)

4
Challenges

• Defining and managing confidential data
• Disseminating results for industrial sources
• Obtaining data from an adequate number of
  facilities
• Obtaining required data to use emission
  methodologies

5
Area Source Categories were Prioritized to Focus
Resources

• Prioritized according to significance
• (H)igh significant PM or VOC emitters
• (M)edium relative significance unknown, data
  availability unknown
• (L)ow insignificant or infrequent sources, data
  difficult to obtain

Participant Roles and Responsibilities
10
What are the Benefits to Industry From
Participating in the Survey?

• Provides accurate data for estimating air
  emissions in place of using assumptions
• Provides TCEQ information about manufacturing and
  industrial processes, allowing TCEQ small
  business assistance programs to develop
  inexpensive control strategies, and reduce
  operational costs and improve margins

11
What are the Benefits to Industry From
Participating in the Survey?

• (Cont.)
• Identifies business owners for participation in
  TCEQ environmental education workshops resulting
  in teaming opportunities with U.S. counterparts
  in El Paso
• Assists in ability to understand operating costs,
  how to reduce emissions, increase operation
  efficiency and improve profitability

12
Relationship of Cd. Juárez Inventory to the
Mexico National Emissions Inventory

• Objectives of the Mexico National Emissions
  Inventory (NEI)
• Promote emissions inventory capacity building
  within Mexico
• Develop first ever national inventory for Mexico
• Support air quality analyses and human exposure
  studies in Mexico
• Support tri-national inventory development
  (Canada, U.S., Mexico)
• Support regional haze planning in the U.S.
• How do these inventories overlap?

Ciudad Juárez Area Sources Emissions Inventory

• Project Kick-off Meeting
• Part II
• Inventory Methodology
• and Survey
• Ciudad Juárez, Chihuahua, Mexico
• January 29, 2003

17
Methodology 1 Determine Source Categories to
Survey

• Estimation methodologies support survey or other
  activity data
• Most high priority source categories, some medium
  and low priority

18
Methodology 2 Determine Specific Data to Collect

• Estimation methodologies dictate activity data to
  collect
• Also important
• Location (for future update to GIS database)
• Controls (for correct calculation, control plans)
• Operation schedule (for seasonal, weekly, daily
  estimates)

19
Area Source Matrix
20
Methodology 3 Organize Survey Forms

• Point Source Questionnaire (PSQ) Previously
  developed by ERG for Mexico Inventory Program
• Area Source Questionnaire (ASQ) Developed
  especially for this project in Cd. Juárez
• Maps of facilities from 1996 database

21
PSQ - Overview

• General forms
• Facility information, general devices, control
  devices, stacks
• Device-specific forms
• Boilers/heaters, solvent degreasing, internal
  combustion engines, incinerators, open process
  tanks, ovens, printing equipment, general solvent
  use, spray booths, storage piles, fixed/floating
  roof storage tanks

22
ASQ - Dry Cleaners

• Operation schedule
• Quantity solvent used
• Perchloroethylene or petroleum solvent
• Quantity solvent recycled
• Quantity solvent disposed

23
ASQ - Cattle Feedlots/Dairies

• Operation schedule
• Number of head per year
• Average number of head present in feedlot/dairy
• Residence time (days)

24
Methodology 4 Identify Facilities to Survey

• Obtain names and telephone numbers from 1996
  database
• Call to ask about operating status, willingness
  to participate, give information over the phone
• Schedule time to interview

25
Methodology 5 Conduct Survey
26
Methodology 6 Compile Results and Quality
Assure

• Surveyors
• Review and correct own work at the end of each
  day
• Submit PSQs and ASQs to ERG (Steve Erickson)
• ERG
• Set up calculation spreadsheets
• Enter PSQs and ASQs into spreadsheets
• Quality check data entry
• Calculate emissions
• Quality check calculations
• Summarize results

27
Methodology 7 Draft and Final Inventory Reports

• Documented methodology
• Completed survey forms/questionnaires and
  compiled results
• Other activity data and assumptions
• Spreadsheet calculations (activity data, emission
  factors, annual/daily emissions)
• Quality assurance procedures
• Summary tables and graphs
