4 EXECUTIVE SUMMARY This report summarizes the quality of the monitoring data from the Continuous Air Monitoring Stations (CAMS) 501, 502, 504, 503, 505 and 506, owned by Alamo Area Council of Governments (AACOG), and operated by Dios Dado Environmental, for the year of 2015 (The months of April 2015 through October 2015). The objectives of this report are to provide and assess the following: The actual data gathered during the monitoring period The quality of the monitored data The data validation performed The amount of data captured for the year of 2015 The incidents that may have led to data loss Assessment of the data quality indicates that the monitoring data collected during the year 2015 met all of the TCEQ regulatory guidelines for Ozone only sites. The monitoring results did suggest exceedances of the National Ambient Air Quality Standards (NAAQS) on a short-term basis, however, these sites do not meet the regulatory requirements for NAQS as set forth by the EPA. These sites are close enough to be excellent sources of ambient data for mapping and research purposes. Pollutants: Ozone (O3), Meteorology: Wind speed, Resultant wind speed, Resultant wind direction, Maximum wind gust, Standard deviation of horizontal wind direction, Outdoor temperature, Indoor temperature, Precipitation events The data collected at the sites this Year was fully representative of ambient conditions in the area. The monitoring instruments all functioned properly or were repaired quickly enough to prevent any data loss this year. Normal calibration and maintenance procedures, which are noted in the logs and all relevant tables, resulted in a loss of some data but not enough to fall below the 75 required. All equipment operations conformed to TCEQ criteria and passed our calibrations during the season. A data return rate of greater than 96.3 (average) was achieved on all the Ozone instruments at the sites for the entire reporting period. AACOG equipment concerns for the 2016 ozone season are as follows: The Thermo Fisher 49C O3 units are passed their useful lifetime and we will no longer be able to obtain spare parts after this ozone season. New units must be budgeted for future site operations. The C502, Fair Oaks Ranch, site will need to be relocated due to building expansion and flora and fauna overgrowth. The school will no longer be able to house the equipment. The C503, Bulverde, site met gear is still on the ground and not installed. The tower is ready to put in when the school gives AACOG the green light for the location. The met gear all needs to be cleaned and overhauled before the next season as well. The AACOG spare unit was deployed at C501 and the C501 unit needs maintenance, then the spare unit got taped by a storm and we had to replace the nose cone with the one from C503, so it needs repaired as well. We are so very pleased to be of service to AACOG and our community, and are pleased with the success of this season operation. Thank you for the opportunity to serve.
