                   Subpart H_Monitoring and Reporting
 
Sec. 96.72  Out of control periods.

    (a) Whenever any monitoring system fails to meet the quality 
assurance requirements of appendix B of part 75 of this chapter, data 
shall be substituted using the applicable procedures in subpart D, 
appendix D, or appendix E of part 75 of this chapter.
    (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 Sec. 96.71 or the 
applicable provisions of part 75 of this chapter, both at the time of 
the initial certification or recertification application submission and 
at the time of the audit, the permitting authority will issue a notice 
of disapproval of the certification status of such system or component. 
For the purposes of this paragraph, an audit shall be either a field 
audit or an audit of any information submitted to the permitting 
authority or the Administrator. By issuing the notice of disapproval, 
the permitting authority revokes prospectively the certification status 
of the system or component. The data measured and recorded by the system 
or component shall 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 Sec. 96.71 for each disapproved system.
