These provisions shall also apply to a unit for which an application for a NOX Budget opt-in permit is submitted and not denied or withdrawn, as provided in subpart I of this part:
(1) Install all monitoring systems required under this subpart for monitoring NOX mass emissions. This includes all systems required to monitor NOX emission rate, NOX concentration, heat input rate, and stack flow rate, in accordance with §§ 75.71 and 75.72 of this chapter.
(2) Install all monitoring systems for monitoring heat input rate.

(3) For the owner or operator of a NOX Budget unit under § 97.4(a) that commences operation on or after January 1, 2003 and that reports on an annual basis under § 97.74(d) by the following dates:
(i) 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; or
(ii) May 1, 2003, if the compliance date under paragraph (b)(3)(i) of this section is before May 1, 2003.
(4) For the owner or operator of a NOX Budget unit under § 97.4(a) that commences operation on or after January 1, 2003 and that reports on a control period basis under § 97.74(d)(2)(ii), by the following dates:
(i) The earlier of 90 unit operating days or 180 calendar days after the date on which the unit commences commercial operation, if this compliance date is during a control period; or
(ii) May 1 immediately following the compliance date under paragraph (b)(4)(i) of this section, if such compliance date is not during a control period.
(5) For the owner or operator of a NOX Budget unit that has a new stack or flue or add-on NOX emission controls for which construction is completed after the applicable deadline under paragraph (b)(1), (b)(2), (b)(3), or (b)(4) of this section or under subpart I of this part and that reports on an annual basis under § 97.74(d), by the earlier of 90 unit operating days or 180 calendar days after the date on which emissions first exit to the atmosphere through the new stack or flue or add-on NOX emission controls.
(6) For the owner or operator of a NOX Budget unit that has a new stack or flue or add-on NOX emission controls for which construction is completed after the applicable deadline under paragraph (b)(1), (b)(2), (b)(3), or (b)(4) of this section or under subpart I of this part and that reports on a control period basis under § 97.74(d)(2)(ii), by the following dates:
(i) The earlier of 90 unit operating days or 180 calendar days after the date on which emissions first exit to the atmosphere through the new stack or flue or add-on NOX emission controls, if this compliance date is during a control period; or
(ii) May 1 immediately following the compliance date under paragraph (b)(6)(i) of this section, if such compliance date is not during a control period.

(c) Commencement of data reporting. (1) The owner or operator of NOX Budget units under paragraph (b)(1) or (b)(2) of this section shall determine, record and report NOX mass emissions, heat input rate, and any other values required to determine NOX mass emissions (e.g., NOX emission rate and heat input rate, or NOX concentration and stack flow rate) in accordance with § 75.70(g) of this chapter, beginning on the first hour of the applicable compliance deadline in paragraph (b)(1) or (b)(2) of this section.
(2) The owner or operator of a NOX Budget unit under paragraph (b)(3) or (b)(4) of this section shall determine, record and report NOX mass emissions, heat input rate, and any other values required to determine NOX mass emissions (e.g., NOX emission rate and heat input rate, or NOX concentration and stack flow rate) and electric and thermal output in accordance with § 75.70(g) of this chapter, beginning on:
(i) The date and hour on which the unit commences operation, if the date and hour on which the unit commences operation is during a control period; or

(3) No owner or operator of a NOX Budget unit shall disrupt the continuous emission monitoring system, any portion thereof, or any other approved emission monitoring method, and thereby avoid monitoring and recording NOX 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 subpart and part 75 of this chapter or except as provided in § 75.74 of this chapter.
(4) No owner or operator of a NOX Budget unit shall retire or permanently discontinue use of the continuous emission monitoring system, any component thereof, or any other approved emission monitoring system under this subpart, except under any one of the following circumstances:

(ii) The owner or operator is monitoring emissions from the unit with another certified monitoring system approved, in accordance with the applicable provisions of this subpart and part 75 of this chapter, by the permitting authority for use at that unit that provides emission data for the same pollutant or parameter as the retired or discontinued monitoring system; or
(iii) The NOX authorized account representative submits notification of the date of certification testing of a replacement monitoring system for the retired or discontinued monitoring system in accordance with § 97.71(b)(2).
