Semiannual Maintenance and Calibration Report Prepared by Air Resource Specialists, Inc. Client: National Park Service Field Personnel: Will Yahr Site: Big Bend NP - (BIBE-KB) Service Date(s): 7/26/217 Site Operator: Price Rumbelow Subject: Semiannual Maintenance All site visit and calibration forms are attached, detailing the pre- and post-maintenance calibrations and test results. Calibration acceptance criteria are defined as the thresholds at which corrective action is required. Data acceptance criteria are defined as the thresholds at which the quality of the ambient data is questionable and may require invalidation. This report is not complete without the inclusion of the calibration form worksheets. 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. (SELECT) 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. Maintenance - No maintenance was performed. Post-Maintenance Testing - No post-maintenance checks were performed. 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 - The ozone inlet and calibration line tubing were replaced. The ozone analyzer was calibrated. 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 49c): Pre-Maintenance Testing - The Level 3 ozone station reference was recertified using a Level 2 ozone transfer standard. The ozone station reference was found to be responding within calibration acceptance criteria. Maintenance - The ozone station reference logger correction factors were updated according to the new certification.

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. Maintenance - Wind speed sensor serial number 1697 was replaced with sensor serial number 2229. 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 outside of 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. Maintenance - Wind direction sensor serial number 222 was replaced with sensor serial number 1813. The wind alignment crossarm was adjusted. 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. 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 performed. Post-Maintenance Testing - No post-maintenance checks were performed. 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 functionality of the heater was not assessed. Maintenance - No maintenance was performed. Post-Maintenance Testing - No post-maintenance checks were performed. 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 and the internal filter was replaced. The internal elbows were inspected and found to be clean. The logger configuration was updated according to the Excel calibration spreadsheet. 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 There are two new operators that will be performing weekly visits to the site. They were present for DataView checklist training and for the tailgate safety meeting.
