§ 123.212. Out-of-control periods for emissions monitors.

 (a)  If an emissions monitoring system fails to meet the quality-assurance and quality-control requirements or data-validation requirements of Chapter 139, Subchapter C (relating to requirements for source monitoring for stationary sources), data for the demonstration of compliance with §  123.207 (relating to annual emission limitations for coal-fired EGUs) shall be substituted using the applicable missing data procedures in the Continuous Source Monitoring Manual (DEP 274-0300-001). If a mass emissions monitoring system fails to meet a quality-assurance or quality-control requirement, mass emissions data shall be substituted using the missing data procedures in 40 CFR Part 75, Subpart I (relating to Hg mass emission provisions).

 (b)  If both an audit of a monitoring system and a review of the initial certification or recertification application reveal that a monitoring system should not have been certified or recertified because it did not meet a particular performance specification or other requirement under §  123.210 (relating to general monitoring and reporting requirements) or the applicable provisions of 40 CFR Part 75 (relating to continuous emission monitoring), 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 monitoring system.

   (1)  For the purposes of this subsection, an audit must be either a field audit or an audit of information submitted to the Department.

   (2)  By issuing the notice of disapproval, the Department revokes prospectively the certification status of the monitoring system. The data measured and recorded by the monitoring system 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 for the monitoring system.

   (3)  The owner or operator shall follow the applicable initial certification or recertification procedures in §  123.210 for each disapproved monitoring system.

   The provisions of this §  123.212 issued under section 5(a)(1) of the Air Pollution Control Act (35 P. S. §  4005(a)(1)).

   The provisions of this §  123.212 adopted February 16, 2007, effective February 17, 2007, 37 Pa.B. 883.
