Air Quality Analysis Section Mission:
- Implements voluntary programs like Energy Star, Cool Communities, Green Lights, etc.
- Coordinates the ambient air monitoring program including ozone, particulate, and air toxics within Region 6 in accordance with national and regional requirements.
- Analyzes ambient air monitoring data to determine compliance with the National Ambient Air Quality Standards.
- Coordinates data collection efforts to support Regional and National needs.
- Coordinates the U.S./Mexico program air specific activities associated with Big Bend and the La Paz agreement.

Subject Area/Current Activities:
Ambient Air Monitoring: EPA Region 6 is responsible for the coordination of all ambient air monitoring activities within the five-state area of Arkansas, Louisiana, Oklahoma, New Mexico, and Texas. Pollutants typically monitored include ozone, particulate matter, carbon monoxide, lead, sulfur dioxide, and oxides of nitrogen. In addition, there are some sites that monitor for volatile organic compounds (VOCs). In addition to regular monitoring, the Region is currently working with the State of Arkansas and Texas in the one-year Pleasant Hill Monitoring Study that will evaluate sulfur dioxide and hydrogen sulfide ambient levels.
Quality Assurance: One of the major aspects of the ambient air monitoring program is the production of quality ambient air monitoring data for EPA and State decisionmakers. Decisions are made with the ambient air monitoring data that impact industry and the general public. Decisions from this data are utilized in determining compliance with the National Ambient Air Quality Standards and ultimately impacts offset decisions for industry, emission reductions, mobile source controls, etc. The Regional Office conducts systems audits and performance audits to ensure the quality of the data. In addition, the Region reviews the Quality Assurance Project Plans developed for ambient air monitoring. Staff members involved in these activities include: John Lay and Kuenja Chung.
Energy Efficiency: The Regional Office promotes the voluntary programs like Energy Star, Green Lights, and Cool Communities through outreach. Staff members involved in these activities include: Pat Kelly.
Air Toxics Monitoring: EPA is beginning efforts to expand ambient air toxics monitoring in all Regions. In FY99, primary emphasis was on expanding air toxics collection at PAMS sites in Houston. Region 6 is also actively involved in developing the Agency's concept paper for Air Toxics Monitoring. Staff members involved in these activities include Ruben Casso, and Kuenja Chung.
PAMS Program: EPA continues to work with the States in the Photochemical Assessment Monitoring Program (PAMS). This program monitors for volatile organics that are precursors to ozone formation. Staff members involved in this activity include Mark Sather.
Tribal Monitoring: Region 6 is working with the tribes in Oklahoma and New Mexico to establish ambient air monitoring sites on tribal lands. Staff members involved in this activity include Regina Krystyn.
Region 6 Air Montoring Sites: |
Below are State air monitoring sites that have been documented and photographed by the Regional Office in order to provide information on the location and what pollutants are being monitored. Click on each site to see photographs of these sites. Other air monitoring sites can be found at State Web sites listed later on this Web page. Most of these ambient air monitoring sites are designated by EPA as National Air Monitoring Stations (NAMS) or State/Local Air Monitoring Stations (SLAMS).

Lake Charles Ambient Air Data Analysis
- Air Toxics
- Trends in air toxics: the following charts are trends in air toxics
for the Westlake site in Calcasieu Parish and compared to three
other air toxic sites in the Region; i.e., Houston Clinton Drive,
Houston Halen, and Austin. The Houston sites are located in an industrial
area; while the Austin site's primary source would be mobile. Click
on the charts below to review.
- Distribution in air toxics: the following charts provide information
on the distribution of the air toxics data around the mean. Approximately
60-61 air toxics samples are collected annually at the Westlake
site.
