Section 225.260  Out of Control Periods for Emission Monitors

a)         Whenever any emissions monitoring system fails to meet the quality-assurance and quality-control requirements or data validation requirements of 40 CFR 75, incorporated by reference in Section 225.140, data must be substituted using the applicable missing data procedures in subparts D and I of 40 CFR 75, each incorporated by reference in Section 225.140.

b)         Audit Decertification.  Whenever both an audit of an emissions monitoring system and a review of the initial certification or recertification application reveal that any emissions monitoring system should not have been certified or recertified because it did not meet a particular performance specification or other requirement pursuant to Section 225.250 or the applicable provisions of 40 CFR 75, both at the time of the initial certification or recertification application submission and at the time of the audit, the Agency must issue a notice of disapproval of the certification status of such monitoring system.  For the purposes of this subsection (b), an audit must be either a field audit or an audit of any information submitted to the Agency.  By issuing the notice of disapproval, the Agency revokes prospectively the certification status of the emissions monitoring system.  The data measured and recorded by the monitoring system must 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 for the monitoring system.  The owner or operator must follow the applicable initial certification or recertification procedures in Section 225.250 for each disapproved monitoring system.
