Article 8
Monitoring, Reporting, and Recordkeeping

A. The owners and operators, and to the extent applicable, the CO2 authorized account representative of a CO2 budget unit shall comply with the monitoring, recordkeeping, and reporting requirements as provided in this section and all applicable sections of 40 CFR Part 75. Where referenced in this article, the monitoring requirements of 40 CFR Part 75 shall be adhered to in a manner consistent with the purpose of monitoring and reporting CO2 mass emissions pursuant to this part. For purposes of complying with such requirements, the definitions in 9VAC5-140-6020 and in 40 CFR 72.2 shall apply, and the terms "affected unit," "designated representative," and "CEMS" in 40 CFR Part 75 shall be replaced by the terms "CO2 budget unit," "CO2 authorized account representative," and "CEMS," respectively, as defined in 9VAC5-140-6020. For units not subject to an Acid Rain emissions limitation, the term "administrator" in 40 CFR Part 75 shall be replaced with "the department or its agent." Owners or operators of a CO2 budget unit who monitor a non-CO2 budget unit pursuant to the common, multiple, or bypass stack procedures in 40 CFR 75.72(b)(2)(ii), or 40 CFR 75.16 (b)(2)(ii)(B) pursuant to 40 CFR 75.13, for purposes of complying with this part, shall monitor and report CO2 mass emissions from such non-CO2 budget units according to the procedures for CO2 budget units established in this article.

B. The owner or operator of each CO2 budget unit shall meet the following general requirements for installation, certification, and data accounting.

1. Install all monitoring systems necessary to monitor CO2 mass emissions in accordance with 40 CFR Part 75, except for equation G-1. Equation G-1 in Appendix G shall not be used to determine CO2 emissions under this part. This may require systems to monitor CO2 concentration, stack gas flow rate, O2 concentration, heat input, and fuel flow rate.

2. Successfully complete all certification tests required under 9VAC5-140-6340 and meet all other requirements of this section and 40 CFR Part 75 applicable to the monitoring systems under subdivision 1 of this subsection.

3. Record, report, and quality-assure the data from the monitoring systems under subdivision 1 of this subsection.

C. The owner or operator shall meet the monitoring system certification and other requirements of subsection B of this section on or before the following dates. The owner or operator shall record, report, and quality-assure the data from the monitoring systems under subdivision B 1 of this section on and after the following dates:

1. The owner or operator of a CO2 budget unit, except for a CO2 budget unit under subdivision 2 of this subsection, shall comply with the requirements of this section by January 1, 2021.

2. The owner or operator of a CO2 budget unit that commences commercial operation July 1, 2021, shall comply with the requirements of this section by (i) January 1, 2022, or (ii) the earlier of 90 unit operating days after the date on which the unit commences commercial operation or 180 calendar days after the date on which the unit commences commercial operation.

3. For the owner or operator of a CO2 budget unit for which construction of a new stack or flue installation is completed after the applicable deadline under subdivision 1 or 2 of this subsection by the earlier of (i) 90 unit operating days after the date on which emissions first exit to the atmosphere through the new stack or flue or (ii) 180 calendar days after the date on which emissions first exit to the atmosphere through the new stack or flue.

D. Data shall be reported as follows:

1. Except as provided in subdivision 2 of this subsection, the owner or operator of a CO2 budget unit that does not meet the applicable compliance date set forth in subsection C of this section for any monitoring system under subdivision B 1 of this section shall, for each such monitoring system, determine, record, and report maximum potential, or as appropriate minimum potential, values for CO2 concentration, CO2 emissions rate, stack gas moisture content, fuel flow rate, heat input, and any other parameter required to determine CO2 mass emissions in accordance with 40 CFR 75.31(b)(2) or (c)(3) or Section 2.4 of Appendix D of 40 CFR Part 75 as applicable.

2. The owner or operator of a CO2 budget unit that does not meet the applicable compliance date set forth in subdivision C 3 of this section for any monitoring system under subdivision B 1 of this section shall, for each such monitoring system, determine, record, and report substitute data using the applicable missing data procedures in Subpart D, or Appendix D of 40 CFR Part 75, in lieu of the maximum potential, or as appropriate minimum potential, values for a parameter if the owner or operator demonstrates that there is continuity between the data streams for that parameter before and after the construction or installation under subdivision C 3 of this section.

a. CO2 budget units subject to an Acid Rain emissions limitation or CSAPR NOX Ozone Season Trading Program that qualify for the optional SO2, NOX, and CO2 (for Acid Rain) or NOX (for CSAPR NOX Ozone Season Trading Program) emissions calculations for low mass emissions (LME) units under 40 CFR 75.19 and report emissions for such programs using the calculations under 40 CFR 75.19, shall also use the CO2 emissions calculations for LME units under 40 CFR 75.19 for purposes of compliance with these regulations.

b. CO2 budget units subject to an Acid Rain emissions limitation that do not qualify for the optional SO2, NOX, and CO2 (for Acid Rain) or NOX (for CSAPR NOX Ozone Season Trading Program) emissions calculations for LME units under 40 CFR 75.19 shall not use the CO2 emissions calculations for LME units under 40 CFR 75.19 for purposes of compliance with these regulations.

c. CO2 budget units not subject to an Acid Rain emissions limitation shall qualify for the optional CO2 emissions calculation for LME units under 40 CFR 75.19, provided that they emit less than 100 tons of NOX annually and no more than 25 tons of SO2 annually.

3. The owner or operator of a CO2 budget unit shall report net-electric output data to the department as required by Article 5 (9VAC5-140-6190 et seq.) of this part.

E. Prohibitions shall be as follows.

1. No owner or operator of a CO2 budget unit shall use any alternative monitoring system, alternative reference method, or any other alternative for the required CEMS without having obtained prior written approval in accordance with 9VAC5-140-6380.

2. No owner or operator of a CO2 budget unit shall operate the unit so as to discharge, or allow to be discharged, CO2 emissions to the atmosphere without accounting for all such emissions in accordance with the applicable provisions of this article and 40 CFR Part 75.

3. No owner or operator of a CO2 budget unit shall disrupt the CEMS, any portion thereof, or any other approved emissions monitoring method, and thereby avoid monitoring and recording CO2 mass emissions discharged into the atmosphere, except for periods of recertification or periods when calibration, quality assurance testing, or maintenance is performed in accordance with the applicable provisions of this article and 40 CFR Part 75.

4. No owner or operator of a CO2 budget unit shall retire or permanently discontinue use of the CEMS, any component thereof, or any other approved emissions monitoring system under this article, except under any one of the following circumstances:

a. The owner or operator is monitoring emissions from the unit with another certified monitoring system approved, in accordance with the applicable provisions of this article and 40 CFR Part 75, by the department for use at that unit that provides emissions data for the same pollutant or parameter as the retired or discontinued monitoring system; or

b. The CO2 authorized account representative submits notification of the date of certification testing of a replacement monitoring system in accordance with 9VAC5-140-6340 D 3 a.
