1 Semiannual Maintenance and Calibration Report Prepared by Air Resource Specialists, Inc. Client: National Park Service Field Personnel: Mike Slate Site: Canyonlands National Park (CANY-IS) Service Date(s): 12/15/215 to 12/16/215 Site Operator: Joe Carlson Subject: Semi-Annual Maintenance All site visit and calibration forms are attached, detailing the pre- and post-maintenance calibrations and test results. SUMMARY OF FINDINGS GASEOUS POLLUTANT SUPPORT EQUIPMENT Zero-Air System (Werther / Panther Compressor PC7/4E): Maintenance - No maintenance for the pump or compressor was required at this time. The media for the zero-air system was replaced. Station Temperature: Pre-Maintenance Testing - The sensor was compared against a certified temperature transfer standard. The sensor was found to be responding within calibration acceptance criteria. GASEOUS POLLUTANT ANALYZERS Ozone Analyzer (Thermo 49c): Pre-Maintenance Testing - The ozone analyzer was compared against a Level 2 ozone transfer standard. The ozone analyzer was found to be responding within calibration acceptance criteria. Maintenance - This analyzer was removed and replaced with 49i to match the onsite transfer standard which is a 49i. Post-Maintenance Testing - The ozone analyzer was compared against a Level 2 ozone transfer standard. The ozone analyzer was found to be responding within calibration acceptance criteria. Ozone Station Reference (Thermo 49i): Pre-Maintenance Testing - The ozone station reference was compared against a Level 2 ozone transfer standard. The ozone station reference was found to be responding within calibration acceptance criteria. Maintenance - The photometer lamp intensity was increased, the tubes were cleaned, and the cooling fan filter was replaced. Post-Maintenance Testing - The ozone station reference was compared against a Level 2 ozone transfer standard. The ozone station reference was found to be responding within calibration acceptance criteria.

2 METEOROLOGICAL SENSORS Ambient Temperature and Vertical Temperature Difference (Climatronics 193): Pre-Maintenance Testing - The sensor was compared against a certified temperature transfer standard in three water baths controlled at temperatures between and 5 degrees Celsius. The sensor was confirmed to be responding within calibration acceptance criteria. Relative Humidity (Rotronic MP61): Pre-Maintenance Testing - The sensor was collocated with a certified relative humidity transfer standard. The sensor was confirmed to be responding within calibration acceptance criteria. The aspirator fan was functioning correctly. Maintenance - The sensor was replaced with a recently refurbished unit. Post-Maintenance Testing - The sensor was collocated with a certified relative humidity transfer standard. The sensor was confirmed to be responding within calibration acceptance criteria. Wind Speed (Climatronics 175): Pre-Maintenance Testing - The sensor was challenged with a certified anemometer drive. The sensor was confirmed to be responding within calibration acceptance criteria. The starting threshold test for the sensor was within acceptance criteria. The heater for the sensor was found to be functioning incorrectly. Maintenance - The sensor was replaced with a recently refurbished unit. Post-Maintenance Testing - The sensor was challenged with a certified anemometer drive. The sensor was confirmed to be responding within calibration acceptance criteria. The starting threshold test for the sensor was within acceptance criteria. The heater for the sensor was functioning correctly. Wind Direction (Climatronics 176): Pre-Maintenance Testing - The reference alignment for the sensor was checked using a compass. The reference alignment for the sensor was confirmed to be within acceptable limits. The accuracy of the sensor was tested by comparison to a reference. The sensor was confirmed to be responding within calibration acceptance criteria. The linearity of the sensor was within acceptable limits. The starting threshold test results were within acceptance criteria. The heater for the sensor was confirmed to be functioning incorrectly. Maintenance - The sensor was replaced with a recently refurbished unit. Post-Maintenance Testing - The reference alignment for the sensor was checked using a compass. The reference alignment for the sensor was confirmed to be within acceptable limits. The accuracy of the sensor was tested by comparison to a reference. The sensor was confirmed to be responding within calibration acceptance criteria. The linearity of the sensor was within acceptable limits. The starting threshold test for the sensor was within acceptance criteria. The heater for the sensor was functioning correctly. Solar Radiation (Li-Cor Pyranometer): Pre-Maintenance Testing - The sensor was collocated with a certified solar radiation transfer standard. The sensor was confirmed to be responding within calibration acceptance criteria. The sensor was found to be level and clean. Maintenance - No maintenance was required.

3 Post-Maintenance Testing - The sensor was collocated with a certified solar radiation transfer standard. The sensor was confirmed to be responding within calibration acceptance criteria. Precipitation (Climatronics 158): Pre-Maintenance Testing - The sensor was challenged using a known volume of water. The sensor was found responding within calibration acceptance criteria. The sensor was found to be level and clean. The heater was found to be functional. PARTICULATE MONITORS AND SAMPLERS CASTNET Filter Pack Flow: Pre-Maintenance Testing - A leak check on the system was performed and results were within acceptable limits. The flow was checked using a certified flow standard measuring flow in standard conditions. The measured flow was found to be within calibration acceptance criteria. Maintenance - The pump was rebuilt, the fittings were cleaned, and the inline filter was replaced. Post-Maintenance Testing - The flow was checked using a certified flow standard measuring flow in standard conditions. The measured flow was confirmed to be within calibration acceptance criteria. ADDITIONAL COMMENTS The shelter is showing its age. This shelter is an old custom wooden shelter. A park electrician recently added some additional outlets to minimize and electrical safety issues in the shelter.

A total of 45 complete cycles were run, whereas only six (one per day) are required. The Ozone Concentrations were run, on an average, at 959, 883, 89, 735, 663, 59, 515, 438, 364, 31, 231, 152, 74 and 22 ppb with a Zero at the start and at the end of each cycle. The instrument Slope was set at Y = 1.X +. and was not altered. The %RSD of all the Slopes should not exceed 3.7% and the Standard Deviation for all the Intercepts should be less than 1.5. (Transfer Standard for Calibration of Air Monitoring Analyzers for Ozone Technical Assistance Document, October 213, see Table 3 1) The next Re Verification will be due by 1/22/16. Scott A.
