(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
