Our Operating Principles Provide our members with the best scientific air quality data available Enable our members to make the best decisions about ways to effectively reduce emissions Share key air monitoring data with TCEQ, City of Houston and Harris County on a routine basis Inform citiz
Slide 7: Our Measuring Process
Our Measuring Process Criteria Air Pollutants (NAAQS) Ozone* (03) Particulate Matter (PM10 and PM2.5) Oxides of Nitrogen* (NOx) Carbon Monoxide* (CO) Sulfur Dioxide* (SO2) Lead Volatile Organic Compounds (VOC) 157 VOCs emitted by industries, utilities, small businesses, vehicles, h
Slide 8: Our Measuring Process
Our Measuring Process VOC samples are taken using EPA-approved methods and equipment One sample every sixth day for a 24-hour period at each monitoring site Approximately 8,000 VOC samples collected by HRM in last 15 years with more than 1 million VOC results obtained from these samples Samp
Slide 9: Our Analysis Process
Our Analysis Process Upon collecting data from monitoring stations, we: Compare to EPA’s National Ambient Air Quality Standards (NAAQS) Compare to known benchmark concentrations Compare with computer modeling results Analyze trends Compare with data from other cities Houston Regional Mon

Slide 14: What We Know: Using TCEQ ESLs As Air Quality Indicator
What We Know: Using TCEQ ESLs As Air Quality Indicator According to TCEQ, Effects Screening Levels (ESLs) are an indicator of air quality for non-NAAQS air pollutants ESLs are established by TCEQ based on data concerning health effects, odor, nuisance potential, vegetation impacts, and corrosion
Slide 15: What We Know: Monitoring Data Indicate Good Air Quality
What We Know: Monitoring Data Indicate Good Air Quality HRM monitoring data compared to ESLs indicate generally good air quality Almost all monitored VOCs are below their annual ESL; most are a small fraction of their annual ESL Benzene has decreased about 80 percent over the last 15 years and
