T&B Systems is performing quarterly performance audits of the PSD monitoring network operated for the Santa Barbara County Air Pollution Control District. The network monitoring includes a full range of continuous gas, meteorological, and particulate monitoring equipment for up to 20 sites during the late 1980s. This project is a continuation of QA/QC services provided to the District by T&B staff since 1986. Until 1994, T&B staff also performed the technical reviews of meteorological and air quality data submitted by the monitoring network contractors to the District to assess their validity and determine whether the data quality control/QA requirements were met. These reviews involved routine, detailed checks of contractors’ procedures for monitoring quality control, data processing and editing. In 1994, using procedures and training provided by T&B Systems staff, the District assumed responsibility for this data validation effort
