Tasks Required i. A minimum of four high visibility enforcement activities, such as checkpoints or saturation patrols, must be performed during the national mobilizations (May Seatbelt, Labor Day Impaired Driving, and Holiday Season Impaired Driving), and
Tasks Required. All monitoring equipment is calibrated once before use at the beginning of the season and during the season according to the Ecology and manufacturer approved process. The one exception are temperature data loggers, which cannot be calibrated, but are checked for drift twice annually: before deployment and following removal at the end of the monitoring season. See the Standard Operating Procedures (SOPs) in Appendix A for calibration procedures. Any temperature data loggers that do not calibrate within the accepted standards are either discarded or sent in for repair. At the end of the season, when the units are brought in, the calibration is checked again. Each monitoring site is visited monthly from May through October and the temperature data are downloaded, then brought back to the office and uploaded. During the site visit when the shuttles are downloaded the time and temperature are taken with the field meters for on-site comparison. The ProPlus and ProODO are checked weekly with the certified NIST thermometer to ensure there is no drift in the temperature readings prior to field visits. The pH is calibrated before each sample day and is checked at the end of the day. The specific conductivity is calibrated weekly and calibration checked before and after each sample day. Dissolved oxygen calibration will be checked each sample day and calibrated as needed (will hold calibration for months). The SonTek FlowTracker ADV is used to measure stream flow. Duplicate measurements are taken once a month at a site and compared for a certain acceptable range of error associated with the measurements taken. A Quality Assurance (QA) check is also performed prior to flow measurement in the stream. If the QA is reading abnormally, the flow tracker is sent in for calibration. The parameters sampled at each site are listed in Table 2. It is important to note that not all sites will be sampled for fecal coliform, just those streams where there are concerns of state water quality criteria exceedances.
