Except for monitoring malfunctions, associated repairs or required quality assurance or control activities, including calibration checks or required zero and span adjustments, you shall conduct all monitoring at all times that the unit is operating. Data recorded during monitoring malfunctions, associated repairs, out-of-control periods or required quality assurance or control activities may not be used for purposes of calculating the emissions concentrations and percent reductions specified in s. NR 466.25 (1). You shall use all the valid data collected during all other periods in assessing compliance of the control device and associated control system. A monitoring malfunction is any sudden, infrequent, not reasonably preventable failure of the monitoring system to provide valid data. Monitoring failures that are caused in part by poor maintenance or careless operation are not malfunctions. NR 466.24(2)(e)8.8. Any averaging period for which you do not have valid monitoring data, and the data are required, constitutes a deviation, and you shall notify the department in accordance with s. NR 466.26 (1) (c).
