CCOS Field Operations Plan Version 2: 5/31/00 Device Manufacturer Model Element Range Bubble meter Teledyne/Hastings 0 - 5 lpm Laminar flow meter Meriam 50MK10 725250-C1 0 - 50 cc/min Laminar flow meter Meriam 50MK10 725250-C2 0 - 1 lpm Laminar flow meter Meriam 50MJ10-1/2 700310-T2 0 - 10 lpm Laminar flow meter Meriam 50MJ10-1/2 700310-T1 0 - 50 lpm Laminar flow meter Meriam 50MW20-1 700310-T3 0 - 200 lpm The Laminar flow devices are certified annually against a primary flow standard by an external laboratory. The bubble flow meter is a primary flow measuring device, and therefore requires no certification. Parsons also maintains a bubble flow meter. Flow Meters - Several flow meters are available as transfer standards for this study. These flow meters and their operating ranges are summarized below: Make Model SN Range Type Bubble-O 0 - 400 ccpm Bubble Bios DC-Lite 0 - 20 lpm Piston Schlumberger Remus 4, G1-6 0 - 20 lpm Dry test Teledyne-Hastings HS-10KS 16045 0 - 10 lpm Mass flow Teledyne-Hastings HS-50JS 16944 0 - 50 lpm Mass flow Teledyne-Hastings HS-10S 17259 0 - 150 lpm Mass flow All flow meters will be certified against suitable flow standards prior to being used in the field. Certifications consist of a comparison between the flow meter and the appropriate QA laminar flow standard at at least 10 different flow spaced evenly across the operating range of the mass flow meter. Continuous Air Quality Analyzers Dilution Standards and Gases - Multipoint audits will be performed using either a Dasibi 1009 CP dilution system, an Environics Series 100 dilution system, or equivalent system. These systems are maintained and the flow rates certified by Parsons’ and the departments. The zero air source will be either a cylinder of Ultra-Pure Air that will be supplied by Scott Specialty Gases or an Aadco 737R pure air system with CH4 burner and compressor capable of delivering a constant 20 lpm air supply. The span gases, except for the SUVA refrigerant, will be provided by Scott Specialty Gases. All gas standard analysis is performed in accordance with EPA Protocols and is traceable to National Institute of Standards and Technology (NIST) standards.) For the CCOS audits, Relative Accuracy Test Audits (RATA) Class cylinders will be used, which are certified to with ±1% of true. SUVA refrigerant will be used to audit the nephelometers. This compound has a known scattering coefficient that is within the nephelometer measurement range. Ozone - All field ozone transfer standards will be certified against a primary standard. Procedures for certification and recertification of ozone primary and transfer standards are based on the EPA technical assistance document, Transfer Standards for Calibration of Air Monitoring Analyzers for Ozone (EPA 1979), EPA-600/4-79-056. All ozone transfer standards used for Chapter 4: QUALITY ASSURANCE 4-8
CCOS Field Operations Plan Version 2: 5/31/00 CCOS will be compared against the California ARB standard photometer prior to the audits. The ozone transfer standards used for CCOS will be an API 400, a Dasibi 5009 MC or a Dasibi 1003 PC ozone analyzer. These ozone analyzers have been converted to a transfer standard configuration in accordance with EPA guidelines (September, 1979). Ozone analyzers that are converted to a transfer standard configuration must be compared to a primary ozone standard by means of a 6 x 6 comparison as the final step in the conversion process. Ozone transfer standards that are in regular use must be compared by means of a 1 x 6 (zero and five upscale concentration points) comparison with the a primary ozone standard twice per quarter. NMOC/carbonyl samplers Laboratory performance audits of the analytical methods for non-methane organic hydrocarbons (NMOCs) and carbonyls will be conducted to assess the accuracy of the methods used by the laboratory to measure the ambient concentrations, as well as the sampling systems. Audits are conducted by supplying the laboratory with a cylinder containing a mixture of target organic hydrocarbons and carbonyl standards prepared by the National Institute of Standards and Technology (NIST). The laboratory analyzes the contents of the cylinder following their normal standard operating procedures. 4.4 System Audit Procedures 4.4.1 Radar Profilers and RASS The system audit of the radar profiler begins with an inspection of the antenna and controller interface cables for proper connection. Antennas and enclosures or clutter fences are inspected for structural integrity. The orientation of the antennas are checked using a magnetic transit and tripod with the observed magnetic readings corrected to true directions using the local magnetic declination. The magnetic orientation measurements are also verified using solar azimuth measurements and latitude and longitude information obtained from handheld GPS. The inclinations of the antennas are measured using a Pro SMARTLEVEL. Measurements are made in at least two directions on the bottom of the antenna array’s support structure. For the multiple antenna systems the inclination angle is also measured and compared to the software setting. A vista diagram is prepared that documents the surroundings of the site. The diagram identifies potential reflective sources for the radar signal, as well as potential active sources that could generate interference. The diagram also provides a description of the view in 30-degree increments around the antenna, including the elevation angle and estimated distance to potential sources. If the configuration of the system allows, an evaluation of the total noise spectrum is performed with the system "listening only," i.e., without transmitting a pulse. The results of this check should produce no measured winds or temperature, or data with very low reliability. If reliable data points are reported at any level, then there is probably an active noise source in the area that is generating frequencies in the operational region of the radar or RASS.
