2 Central Texas Final Report Monitoring Program SUMMARY As part of an air quality monitoring program for the Central Texas region, Capital Area Council of Governments (CAPCOG) and Air Quality Solutions, Inc. (AQSI), in collaboration with the Texas Commission on Environmental Quality (TCEQ) and the Lower Colorado River Authority (LCRA), operated several Continuous Air Monitoring Stations, CAMS 601, CAMS 614, CAMS 6602, (CAMS 675/1675), CAMS 684, and CAMS 690, in counties surroundings Travis county; Hays, Fayette, Bastrop, & Williamson County. Ozone data collection began in April 15, 2011 and ended on October 31, Measurements for ozone were made continuously during this period, except for interruptions including analyzer malfunction, calibrations, and equipment checks. In addition to the monitoring sites listed above are operated by AQSI, two regulatory monitoring stations are operated by TCEQ in Travis County, CAMS 3 & 38. NO x and meteorological measurements of Wind Speed and Wind Direction were also made at the CAMS 38, 614 and 6602 sites through the sample period. SO 2 and meteorological measurements were augmented at the CAMS 6602 site. The One-hour data summary for all sites in 2011 indicated; the highest one-hour average ozone concentration recorded at CAMS 03 was 88 ppb; CAMS 38 was 83 ppb, CAMS 614 was 96 ppb;; CAMS 6602 was 86 ppb; CAMS 601 was 85 ppb; and CAMS 675/1675 was 99 ppb; CAMS 684 was 86 ppb; CAMS 690 was 91 ppb. The fourth-highest 8-hour data summary for all sites in 2011 indicated; the fourth highest 8-hour average ozone concentration at CAMS 03 was 75 ppb; CAMS 38 was 73 ppb, CAMS 614 was 77 ppb;; CAMS 6602 was 75 ppb; CAMS 675/1675 was 78 ppb, CAMS 684 was 72 ppb, CAMS 690 was 71 ppb; and CAMS 601 was 75 ppb.

3 Central Texas Final Report Monitoring Program I. INTRODUCTION Air quality in Central Texas is generally good, however, when cloud cover is negligible and winds are light, the concentrations of some pollutants can reach unhealthful levels. The air pollutant that approaches unhealthful levels over the widest area with the greatest frequency is ozone. Ozone (O 3 ) formed in the lower atmosphere is a concern because it can damage the respiratory system. In addition, as a strong oxidant it can damage materials and harm crops. In order to preserve public health and welfare, the U.S. Environmental Protection Agency sets standards for the maximum allowable concentrations of air pollutants, such as ozone, in ambient air. On March 12, 2008 the EPA lowered the National Ambient Air Quality Standards ( NAAQS) for ground-level ozone, from the 1997 standard of 84 parts per billion (ppb), to 75 ppb. Attainment of the ozone NAAQS is based on the 3-year average of the fourth-highest daily maximum 8-hour average ozone concentrations measured annually at each regulatory monitor in a given region, i.e. CAMS 3 & CAMS 38. This 3-year average is called the design value. If a region s design value is 76 ppb or higher, that region has exceeded the federal standard and may be designated nonattainment by the EPA. Table I-1 reports the fourth highest daily maximum ozone concentrations (8-hour average) recorded in the Austin area since Table I-2 shows the rolling three-year averages calculated for the Austin area from Austin has historically been in attainment of the 1-hour average NAAQS for ozone. However, with respect to the EPA s new 8-hour ozone standard, it is questionable whether Austin will be able to maintain its attainment status for clean air in the future. EPA may use the previous 3 years of data from 2009, and 2010 and 2011 to determine Austin s attainment status. Final Report 2011 AQSI 3

5 Central Texas Final Report Monitoring Program Working in cooperation with the Texas Commission on Environmental Quality (TCEQ), the Lower Colorado River Authority (LCRA), and the Capital Area Council of Governments (CAPCOG), Air Quality Solutions, Inc. (AQSI) collected ambient air quality data during the summer of 2010 at CAMS 601 located in Fayette County (Fayette Power Plant), CAMS 614 located in Northwest Hays County (Dripping Springs), CAMS 674 (Round Rock) was re-located in the winter to Hutto CAMS 6602 and is located in Eastern Williamson County), CAMS 675 was re-located in mid September 2011 and re-named to CAMS 1675 and remains within the city of San Marcos in Southeast Hays County, CAMS 684 located in Northwest Bastrop County (McKinney Roughs), and CAMS 690 located in central Williamson County (Georgetown). The both CAMS 614 Dripping Springs and Hutto CAMS 6602 sites were equipped with ozone, and NO x, monitors as well as a multi-gas calibrator and a ZENO data logging system to supplement existing meteorological monitoring equipment. Data capture for the Central Texas region during the 2011 sampling period averaged 89 to 98 % for ozone, NOx & SO2 respectively. The wind directions in Austin during ozone action days are usually from the Northeast, East & Southeast. Due to the position of CAMS 601 to East/Southeast of Austin, ozone concentrations measured at this site provides information on levels of ozone and NO x entering the Austin area on typical summer days. In 2011, the CAMS 601 site remained the only true background site and is located approximately 60 miles east of the Austin/San Antonio metropolitan area. Overall air quality measurements were made from April through October 31, 2011 at the CAMS 601 site. This report will describe the research data collected from all ozone monitoring sites including the TCEQ and CAPCOG CAMS sites in the Austin area. The days in which the wind direction in Austin, during ozone action days, is not from the Southeast makes the entire network of all ozone sites very important in understanding the local influence versus transport from other regions. Additional analyses of monitoring and other meteorological data for evaluating source regions for high ozone measured at the Austin area monitors can be found in the conceptual model done by UT-CEER.

7 Central Texas Final Report Monitoring Program III. SAMPLING LOCATIONS AND METHODS III.1 Sampling Locations The CAMS 601 Fayette County site is located approximately 60 miles southeast of Austin near La Grange, Texas. The CAMS 614 Dripping Springs site is located approximately 18 miles southwest of the Austin downtown area within the Dripping Springs city limits. The CAMS 674 Round Rock site was decommissioned over the winter months/ the equipment is re-located to Hutto CAMS 6602 and is approximately 25 miles northeast of the downtown Austin area.. The CAMS 675 San Marcos site was re-located, on Sept 21, 2011, to the east of I-35, and re-named CAMS 1675, this new site is approximately 25 miles south of Austin and approximately 2 miles east of IH-35 and remains within the San Marcos city limits. The CAMS 684 McKinney Roughs site is located approximately 19 miles east of downtown Austin area near Bastrop, Texas. The CAMS 690 Lake Georgetown site is located approximately 25 miles north of the downtown Austin area and is located within Cedar Breaks Park. The location of these sites is shown on the map on Figure III-1. The TCEQ reports the daily maximum concentrations from CAMS 3, 38 & 614 sites to the U.S. Environmental Protection Agency (EPA). Air Quality Solutions, Inc. (AQSI) installed ambient monitoring equipment provided by CAPCOG/ TCEQ, specifically an ozone analyzer, a NO x analyzer, and an SO 2 analyzer at selective sites as well as a Dasibi 5008 multi-gas calibrator and a ZENO data logging system all provided by CAPCOG/TCEQ. This system, known as the MeteoStar Environmental Monitoring System (MeteoStar EMS), controls all routine measurement functions, including calibrations (as described later in this report). The archived data are available at the TCEQ s web site ( Hourly averages of ozone, resultant wind speed, and resultant wind direction were downloaded daily over the Internet and were stored on a personal computer hard drive. The files were backed-up to disk once a week. Monitoring of ambient concentrations of ozone at all sites, and NO x, and SO 2 at specific sites was performed from April 15, 2011 through October 31, Meteorological data was also collected during this period. Table III-1 presents a summary of the technologies that were used to make the measurements. Sample periods for each measurement are also indicated in Table III-1. Quantitative objectives for data quality are listed in Table III-2. Final Report 2011 AQSI 7

9 Central Texas Final Report Monitoring Program III.2 Sampling Methods III.2.1 Ozone (O 3 ), Oxides of Nitrogen (NO x ), and Sulfur Dioxide (SO 2 ) O 3 measurements were made using an ultraviolet absorption analyzer operating in the range of 0 to 400 ppb. Instruments had a minimum detectable sensitivity of 1 ppb. All connections to the ozone photometric analyzer that contacted the ambient sample were constructed of Teflon, glass, or other inert materials. The air sampling line was equipped with a 0.5 μm Teflon filter placed near the instrument inlet. Nitric oxide concentrations were measured by AQSI using O 3 chemiluminescence. The instrument operated within the dynamic range of 0 to 470 ppb. Operation in this range allowed the instrument to achieve a detection limit of 1.0 ppb. All connections to the instrument that contacted the ambient air sample or the quality control standards were constructed of Teflon, glass, or other inert materials. The air sampling line was equipped with a 0.5μm Teflon filter placed near the instrument inlet. Sulfur dioxide concentrations were measured by AQSI using fluorescence. The instrument operated within the dynamic range of 0 to 400 ppb. Operation in this range allowed the instrument to achieve a detection limit of 1.0 ppb. All connections to the instrument that contacted the ambient air sample or the quality control standards were constructed of Teflon, glass, or other inert materials. The air sampling line was equipped with a 0.5μm Teflon filter placed near the instrument inlet. Only CAMS 3, 38 & 614 ozone & NOx continuous gas monitoring equipment were subject to a two-point span-zero once a day, a three-point span check every two weeks, and a five-point calibration once a month throughout the study period. CAMS 601, (675/1675), 6602, 690, & 684 takes exception to the calibration standards set forth for ozone in the Quality Assurance Project Plan (QAPP). In addition, calibration of a continuous gas monitor was performed after any equipment maintenance or repair that may have affected instrument response or if quality control standards were found to be outside the specific quality control limits. The calibration requires the analysis of four standard concentrations, not including zero, without adjustment of the instrument. All calibration gas standards were from a source of known and documentable concentration. SO 2 calibration was done directly using an SO 2 cylinder. NO and NO 2 measurements were calibrated using an NO cylinder. NO Final Report 2011 AQSI 9

10 Central Texas Final Report Monitoring Program calibration was done directly. NO 2 calibrations were performed by titration of the NO with controlled amounts of ozone. A Dasibi Model 5008 multi-gas calibrator produced ozone used in the calibrations. A minimum of five data points, including zero, spanning the working range of the instrument were used to conduct the calibrations. III.3 Sampling Schedule Air quality measurements were made from April 15, 2011 to October 31, 2011 for CAMS 601, 614, 6602, 675, 684 and 690. Continuous monitoring for ozone, NO x, (NO x not measured at CAMS 675/1675, or 684) SO 2, (SO 2 not monitored at CAMS 614, 675, or 684) wind speed, and wind direction was performed at CAMS 601, 614, 6602, (675/1675), 684, and 690 twenty-four hours a day, every day. Although data monitoring and collection was continuous, some data were lost due to equipment malfunction, routine calibrations, and a few limited data system problems. These limited data gaps are noted in the data volume.

11 Central Texas Final Report Monitoring Program IV. RESULTS AND DISCUSSION The results of the study are organized into sections of ozone concentrations per monitoring site and ozone precursor concentrations when available. IV.1 Ozone Concentrations in Central Texas and Regional Transport of Ozone Daily imum Ozone Concentrations Daily maximum 1-hour average ozone concentrations observed in Central Texas are reported in Figures IV-1 through IV-15, and listed in Table IV-1. The top ten daily 1- hour maximum ozone concentrations in 2010 at CAMS 601, 614, 6602, (675/1675), 684, 690, 3, and 38 were typically between 60 and 90 ppb. The highest one-hour average ozone concentration recorded at CAMS 03 was 88 ppb; CAMS 614 was 96 ppb; CAMS 38 was 83 ppb; CAMS 6602 was 86 ppb; CAMS 601 was 85 ppb; and CAMS (675/1675) was 99 ppb; CAMS 684 was 86 ppb; CAMS 690 was 91 ppb In 2011 the fourth highest 8-hour average ozone concentration recorded at CAMS 03 was 75 ppb; CAMS 614 was 77 ppb; CAMS 38 was 73 ppb; CAMS 6602 was 75 ppb; CAMS (675/1675) was 78 ppb, CAMS 684 was 72 ppb, CAMS 690 was 71 ppb; and CAMS 601 was 75 ppb. Daily 8-hour ozone maxima for Central Texas are shown in Figures IV-16 through IV-31. During the Central Texas year 2011 monitoring program some data was lost due to instrument repairs/replacement, communication challenges, and in some instances logistical challenges. All ozone monitors were audited by a 5 and 3 point calibration check each month and sample filters were replaced every two weeks. *Note: With respect to the NAAQS for ozone, two sites, recorded a 4 th highest ozone concentration of 76 ppb or above. CAMS 614, CAMS (675/1675) ( see chart for all sites), However the 4 th Highest 3-Year rolling ozone average concentration remains within the EPA s clean air attainments status of the NAAQS for Ozone Final Report 2011 AQSI 11
