<strong>CCOS</strong> Field Operations Plan (DRAFT) Version 2: 5/31/00<br />
and tridecane for the NO 2 /PAcN analyzers. Each analyzer will be calibrated at zero and at up to<br />
five upscale points, except tridecane which will only be at one level. Each measurement will<br />
have a standard operating procedure that lists the specific tasks required of the site operator.<br />
They will also contain information on procedure for handling problems and personnel to contact<br />
for assistance. DRI will install NO/NOy analyzers at S0 and S1 sites.<br />
T&B will be responsible for operating the Bodega Bay (S1), Turlock (S1), and Pecheco<br />
Pass (S2) sites. Personnel will be present during installation of equipment and will be available<br />
for training. Training for the Pecheco Pass site will also include training for the gas analyzers.<br />
UCB will be responsible for operating the Sunol (R) and Altamont (S2) sites. Personnel<br />
will be present during installation of equipment and will be available for training. These two<br />
sites are heavily equipped but have several instruments in common.<br />
The VOC canister samplers will be installed by Biospheric <strong>Research</strong> Corporation and<br />
<strong>Desert</strong> <strong>Research</strong> <strong>Institute</strong> for the sites indicated in Table 2.4-3. AtmAA will install carbonyl<br />
cartridge samplers at all <strong>CCOS</strong> supplemental sites. The site operators will need to be present<br />
during installation to provide assistance and to insure that the samplers are installed properly and<br />
do not adversely affect the current operations. Training of the site operators on sampler<br />
operations will be done at the time of installation.<br />
DRI will perform final calibrations of the O 3 analyzers, CO analyzers, CO 2 analyzers,<br />
calibration systems, data loggers (at S0, S1, and S2 sites), CRPAQS DAS (at research sites),<br />
diode array spectrometers for actinic flux measurements, particulate nitrate analyzers,<br />
Aethalometers, and nephelometers. Full onsite calibrations will be performed on the O 3 ,<br />
NO/NOx, CO, CO 2 analyzers, particulate nitrate analyzers and the nephelometers. The diode<br />
array spectrometers will be calibrated onsite with a field lamp and in Reno after the study. The<br />
flow meters and ozone generators of the calibration systems will be checked after return to Reno.<br />
CE-CERT will perform final calibrations of the NO/NOx analyzers, NO/NOy,<br />
NOy/NOy*, HCHO, and the NO 2 /PacN analyzers analyzers at S2 and R sites. Full calibrations<br />
will be done for each analyzer. This will include NO, NO 2 , nitric acid, and NPN for the NO/NOy<br />
and NOy/NOy analyzers; HCHO for the HCHO analyzers, and NO 2 and tridecane for the<br />
NO 2 /PAcN analyzers. Each analyzer will be calibrated at zero and at up to five upscale points,<br />
except tridecane which will only be at one level.<br />
T&B will assist in the final calibrations and instrument removal at the Bodega Bay (S1),<br />
Turlock (S1), and Pecheco Pass (S2) sites. UCB will assist in the final calibrations and<br />
instrument removal at the Sunol (R) and Altamont (S2) sites. VOC canister samplers and the<br />
carbonyl cartridge samplers will be removed by the respective contractors.<br />
2.4.6 Site Operations<br />
<strong>CCOS</strong> supplemental analyzers will be calibrated daily using automated calibration<br />
systems. Details of the calibration methods and standards that will be used are summarized in<br />
Table 2.4-4. Automatic calibration checks will be made daily for the O3, NO/NOX, NO/NOY,<br />
