Introduction

• Purposes
• - To create database for identifying pollutant
  point emission source and monitoring site by
  using GIS ArcMap
• - To determine the magnitude and variability of
  non-routine emissions (called Event Emission)
  relative to average annual emissions
• - To find remarkable monitoring sites for Event
  Emission
• Focus is on total volatile organic compounds
  (VOC) and highly reactive volatile organic
  compounds (HRVOC) ethene, propene, butene, and
  1,3-butadiene

Data Collection

• Pollutant Point Sources
• VOC emissions from TCEQ (2000)
• Air Emission Event Reports from TCEQ (2003)

• Monitoring Sites
• CAMS from TCEQ
• VOC measurement in monitoring site from EPA
  (2002) 200MB

1. Sorting Data by Using MS Access by county and
   type of VOC
2. Organizing in Excel
3. Save as DBF file for Attribute table in ArcMap

Conclusions

• Spatially distributed emission sources and
  monitoring sites by GIS ArcMap allows one can
  recognize the actual location.
• Linked database of emission sources and
  monitoring sites leads convenience of data
  access.
• Monitoring sites which mainly detect Event
  Emissions would be considered as remarkable
  monitoring sites for sudden upcoming Event
  Emissions.
