   (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.

§ 123.213.  Monitoring of gross electrical output.

   The owner or operator of an EGU complying with the requirements of § 123.206(d) (relating to compliance requirements for the emission standards for coal-fired EGUs) using electrical output (Oi) shall monitor gross Oi of the associated generators and report in watt-hours per hour.

§ 123.214.  Coal sampling and analysis for input mercury levels.

   (a)  Except as provided in § 123.210(c) (relating to general monitoring and reporting requirements), the owner or operator of an EGU complying with this section and §§ 123.201--123.213 and 123.215 shall:

   (1)  Perform daily sampling of the coal combusted in the EGU for mercury content, in pounds per trillion Btu, as follows:

   (i)  Collect coal samples from the feeders or other representative location in accordance with 40 CFR 63.7521(c) (relating to what fuel analyses and procedures must I use?).

   (ii)  Composite coal samples in accordance with the requirements of 40 CFR 63.7521(d).

   (2)  Analyze each of the composited coal samples for mercury content in accordance with the procedures of ASTM D 6414-01 or the current revision of this method, or other alternative as approved by the Department.

   (b)  The owner or operator of an EGU shall use the data collected from the sampling and analysis required under subsection (a) to determine the input mercury content of the coal combusted in the EGU in terms of pounds of mercury per trillion Btu.

   (c)  The Department may change the frequency of the sampling and analysis of the coal combusted in the EGU for the input mercury level based on historical data provided by the owner or operator of the EGU. The change in the frequency will be approved by the Department as a minor modification to the Title V operating permit.

   (d)  Upon the written request of an EGU owner or operator, the Department may approve, in writing, an alternate coal sampling and analysis program submitted by the owner or operator of the EGU to demonstrate compliance with this section and §§ 123.201--123.213 and 123.215.

§ 123.215.  Recordkeeping and reporting.

   (a)  The owner or operator of an affected EGU shall comply with the recordkeeping and reporting requirements in this section and the applicable recordkeeping and reporting requirements of 40 CFR 75.84 (relating to recordkeeping and reporting) and Chapter 139, Subchapter C (relating to requirements for source monitoring for stationary sources).

   (b)  The owner or operator of an affected EGU complying with this section and §§ 123.201--123.214 through the requirements of § 123.206(d) (relating to compliance requirements for the emission standards for coal-fired EGUs) by using electrical output to determine the allowable emissions of the EGU shall maintain the daily gross electrical output in GWhs in the file required under 40 CFR 75.84(a).

   (c)  The owner or operator of an affected EGU complying with this section and §§ 123.201--123.214 through the requirements of § 123.206(e) by using input mercury levels to determine the allowable emissions of the EGU shall maintain the daily mercury content of coal used in pounds of mercury per trillion Btu and the daily input mercury content in pounds in the file required under 40 CFR 75.84(a).

   (d)  Except as provided in § 123.210(c) (relating to general monitoring and reporting requirements), the owner or operator of an affected EGU shall maintain records as follows:

   (1)  Record the daily outlet mercury or output mercury data using the time period appropriate to the excepted monitoring system (sorbent trap monitoring system).

   (2)  If using an averaging methodology, record all other information collected on a daily basis necessary to calculate the average.

   (3)  Record for each control period the method through which each EGU demonstrated compliance.

   (4)  For an owner or operator who uses the averaging option of § 123.206(a)(2), calculate and record:

   (i)  The monthly actual mercury emissions within 30 days of the end of each month.

   (ii)  The 12-month rolling actual emissions each month.

   (5)  Maintain the following records onsite:

   (i)  The results of quarterly assessments conducted under 40 CFR Part 75, Appendix B, Section 2.2 (relating to quality assurance and quality control procedures).

   (ii)  Daily/weekly system integrity checks under 40 CFR Part 75, Appendix B, Section 2.6.

   (iii)  Quality assurance records as required by the Continuous Source Monitoring Manual (DEP 274-0300-001).

   (6)  Make available to the Department upon request the records required under paragraph (5).

   (e)  The owner or operator shall submit quarterly reports to the Department in accordance with the Continuous Source Monitoring Manual (DEP 274-0300-001).
