1 Twice-Annual Station Maintenance and Calibration Report CANYONLANDS NATIONAL PARK March 3, 21 National Park Service Gaseous Pollutant Monitoring Program Prepared by Air Resource Specialists, Inc. under Contract C CALIBRATION SUMMARY Air quality site: Island in the Sky Field Specialist: Dave Meisters Primary Site Operator: Lofton Wiley Backup Site Operator: Kevin Moore All site visit and calibration forms are attached, detailing the pre- and post-maintenance calibrations. Pre-Maintenance Calibration Summary: The ozone analyzer and station reference were both found to be about +6. Maintenance Activity Summary: O 3 The analyzer was found to be +6. The sample pump diaphragm and photometer tubes were installed. Analog output was in need of adjustment; the analyzer displayed a coefficient higher than expected. Both instruments were calibrated. After calibration, the correlation coefficients were back to normal, and no further maintenance was performed. The dryer has failed in the zero air source, as it is indicating desiccant. The compressor s water drop-out bottle leaks air, and the ¼ line is poorly installed; holes have worn through because of the vibration. A replacement Panther with 8 of ¼ tubing (with stainless steel swage lock fittings and tubing tie-downs) will be shipped. WS/WD The cross arm was checked for proper N/S orientation, and it was found to be two (2) degrees low. The sensors were checked for proper orientation and accuracy, and then replaced. Orientation and accuracy checks were repeated for the new sensor, and once the orientation ring was adjusted to correct for a 12 degree offset (probably from the lab rebuild), the final checks passed. The translator was not adjusted. T/ T Calibration checks were performed on the upper and lower temperature sensors at three (3) temperature baths, with very good results. The aspirator fans were found in working condition. The translator was not adjusted. SR A pre-maintenance calibration check of the solar radiation sensor showed that it responded 4 low compared to the reference. The sensor found level and clean. The translator was not adjusted. The post-maintenance side-by-side comparison was recorded. PRECIP The precipitation gauge was reading accurately, and the tipping mechanism was found to be clean and level. No adjustments were necessary. 191 Sharp Point Drive, Suite E Fort Collins, CO 8525 Telephone:

2 WETNESS The wetness sensor, which was exposed in the surrounding snow, was tested and produced expected results. RH The relative humidity sensor was found in good agreement with the reference sensor during pre-maintenance checks. The aspirator fan was in working condition. The sensor was replaced as routine maintenance, and the post-maintenance comparisons are documented. CASTNet Pre-maintenance flow checks passed, and the calibration procedure was not performed. A new diaphragm was installed. Post-Maintenance Calibration Summary: All parameters were within specifications. ADDITIONAL NOTES AND OBSERVATIONS Station Operator The park's law enforcement personnel take turns doing the weekly station visits. They take care to follow SOPs, but often need to perform minimal maintenance due to understaffing. Lofton was able to meet with me to allow access to the shelter and to assist with the meteorological readings during the performance checks. He does a good job and is responsive when problems arise at the site. Monitoring Shelter and Supporting Hardware The 8 ft. x 7 ft. wooden shelter is in poor condition, with bad door seals and many signs of dirt and dust intrusion. The j-box at the base of the tower should be replaced to accommodate for power requirements, and the system should be replaced as well. Bolts are missing from the flow tower unistrut clips (actually, it is doubtful that there ever were bolts because the clips are too small). Fence wire is being used instead, but is not adequate; the tower is loose on the shelter mount. The guy wires on the meteorological tower have rusty wire clamps. 191 Sharp Point Drive, Suite E Fort Collins, CO 8525 Telephone:
