§ 123.211. Initial certification and recertification procedures for emissions monitoring.

 (a)  By the applicable deadline specified in §  123.210 (f)—(h) (relating to general monitoring and reporting requirements), the owner or operator of an affected EGU shall comply with the following initial certification and recertification procedures for a continuous monitoring system (continuous emission monitoring system) and an excepted monitoring system (sorbent trap monitoring system) as required under 40 CFR 75.15 (relating to special provisions for measuring Hg mass emissions using the excepted sorbent trap monitoring methodology) and Chapter 139 (relating to sampling and testing):

   (1)  The owner or operator of the EGU shall ensure that each continuous monitoring system required by the applicable provisions of §  123.210 successfully completes all of the initial certification testing required under 40 CFR 75.80(d) (relating to general provisions) and Chapter 139.

   (2)  If the owner or operator of the EGU installs a monitoring system to meet the requirements of this section and § §  123.210 and 123.212—123.215 in a location where no monitoring system was previously installed, initial certification testing is required in accordance with the applicable provisions of 40 CFR 75.80(d) and Chapter 139.

   (3)  If the owner or operator of the EGU makes a replacement, modification or change to a certified continuous emission monitoring system or excepted monitoring system (sorbent trap monitoring system) required by §  123.210 that may significantly affect the ability of the system to accurately measure or record mercury mass emissions or heat input rate or to meet the quality-assurance and quality-control requirements of 40 CFR 75.81 (relating to monitoring of Hg mass emissions and heat input at the unit level) or 40 CFR Part 75, Appendix B (relating to quality assurance and quality control procedures), the monitoring system for the EGU shall be recertified in accordance with 40 CFR 75.20(b) (relating to initial certification and recertification procedures) and Chapter 139.

   (4)  If the owner or operator of the EGU makes a replacement, modification or change to the flue gas handling system or the operation of the EGU that may significantly change the stack gas flow or concentration profile, the owner or operator shall recertify each continuous emission monitoring system and each excepted monitoring system (sorbent trap monitoring system) whose accuracy is potentially affected by the change in accordance with 40 CFR 75.20(b) and Chapter 139.

   (5)  This subsection applies to both the initial certification and recertification procedures of a continuous monitoring system required by §  123.210. For recertifications, replace the words ‘‘certification’’ and ‘‘initial certification’’ with the word ‘‘recertification,’’ replace the word ‘‘certified’’ with the word ‘‘recertified,’’ and follow the procedures required under 40 CFR 75.20(b)(5) or Chapter 139, Subchapter C (relating to requirements for source monitoring for stationary sources) as directed by the Department instead of the following procedures:

     (i)   The owner or operator shall submit to the Department written notice of the dates of certification testing.

     (ii)   The owner or operator shall submit to the Department a certification application for each monitoring system. A complete certification application must include the information specified in Chapter 139, Subchapter C.

     (iii)   If the Department issues a notice of disapproval of a certification application or a notice of disapproval of certification status, the owner or operator shall:

       (A)   Substitute, for each disapproved monitoring system, for each hour of EGU operation during the period of invalid data specified under 40 CFR 75.20(a)(4)(iii) or 75.21(e) (relating to quality assurance and quality control requirements) and continuing until the applicable date and hour specified under 40 CFR 75.20(a)(5)(i), either the following values or, if approved by the Department in writing, an alternative emission value that is more representative of actual emissions that occurred during the period:

         (I)   For a disapproved mercury pollutant concentration monitor and disapproved flow monitor, respectively, the maximum potential concentration of mercury and the maximum potential flow rate, as defined in 40 CFR Part 75, Appendix A, Sections 2.1.4.1 and 2.1.7.1 (relating to specifications and test procedures).

         (II)   For a disapproved moisture monitoring system and disapproved diluent gas monitoring system, respectively, the minimum potential moisture percentage and either the maximum potential CO₂ concentration or the minimum potential O₂ concentration (as applicable), as defined in 40 CFR Part 75, Appendix A, Sections 2.1.3.1, 2.1.3.2 and 2.1.5.

         (III)   For a disapproved excepted monitoring system (sorbent trap monitoring system) under 40 CFR 75.15 and disapproved flow monitor, respectively, the maximum potential concentration of mercury and maximum potential flow rate, as defined in 40 CFR Part 75, Appendix A, Sections 2.1.4.1 and 2.1.7.1.

       (B)   Submit a notification of certification retest dates and a new certification application in accordance with subparagraphs (i) and (ii).

       (C)   Repeat all certification tests or other requirements that were failed by the monitoring system, as indicated in the Department’s notice of disapproval, within the time period specified by the Department in the notice of disapproval.

 (b)  The owner or operator shall submit a certification application to the Department within 45 calendar days after completing all initial certification or recertification tests required under this section.
