Deviation is defined as a departure from an indicator range or work practice for monitoring, consistent with any averaging period specified for averaging the results of the monitoring. What are the requirements if a deviation occurs?

The reports are due September 30th for all deviations that occurred during the first six calendar months, and March 31st for the last six calendar months.
