(7) Except for the CPMS in paragraphs (2) and (3), calculate the daily average for each monitored parameter for each operating day using the data recorded by the CPMS. Valid data points must be available for 75% of the operating hours in an operating day to compute the daily average where the operating day is:
(i) A 24-hour period if the control device operation is continuous.
(ii) The total number of hours of control device operation per 24-hour period.
(8) Except as specified in subparagraph (iii), do both of the following:
(i) Ensure the data recorded by the CPMS is used to assess the operation of the control device and associated control system.
(ii) Report the failure to collect the required data in paragraph (1) as a deviation of the monitoring requirements.
(iii) The requirements of subparagraphs (i) and (ii) do not apply during:
(A) A monitoring system malfunction.
(B) A repair associated with a monitoring system malfunction.
(C) A required monitoring system quality assurance or quality control activity.
(9) Determine compliance with the established parameter value by comparing the calculated daily average to the established operating parameter value as follows:
(i) For a minimum operating parameter established in paragraph (6)(i)(A) or paragraph (6)(ii)(A), the control device is in compliance if the calculated value is equal to or greater than the established value.
(ii) For a maximum operating parameter established in paragraph (6)(i)(B) or paragraph (6)(ii)(B), the control device is in compliance if the calculated value is less than or equal to the established value.
