§ 145.72. Out of control periods.
(a) Quality assurance requirements. Whenever a monitoring system fails to meet the quality assurance or data validation requirements of 40 CFR Part 75 (relating to quality assurance and quality control procedures), data shall be substituted using the applicable procedures in 40 CFR Part 75 Subpart D, Appendix D or Appendix E (relating to missing data substitution procedures; optional SO2 emissions data protocol for gas-fired and oil-fired units; and optional NOx emissions estimation protocal for gas-fired peaking units and oil-fired peaking units).
(b) Audit decertification. Whenever both an audit of a monitoring system and a review of the initial certification or recertification application reveal that any system or component should not have been certified or recertified because it did not meet a particular performance specification or other requirement under § 145.71 (relating to initial certification and recertification procedures) or the applicable provisions of 40 CFR Part 75, both at the time of the initial certification or recertification application submission and at the time of the audit, the Department will issue a notice of disapproval of the certification status of the system or component. For the purposes of this subsection, an audit shall be either a field audit or an audit of any information submitted to the Department or the Administrator. By issuing the notice of disapproval, the Department revokes prospectively the certification status of the system or component. The data measured and recorded by the system or component will not be considered valid quality-assured data from the date of issuance of the notification of the revoked certification status until the date and time that the owner or operator completes subsequently approved initial certification or recertification tests. The owner or operator shall follow the initial certification or recertification procedures in § 145.71 for each disapproved system.
