a)         Recordkeeping.  The owner or operator of any unit included in an emissions averaging plan (e.g., affected units, nonsubject units, units that could be exempt under Section 217.386(c), and low usage units) or an affected unit that is not exempt under Section 217.386(c) and is not subject to the low usage exemption of Section 217.388(a)(3) must maintain records that demonstrate compliance with the requirements of this Subpart Q, which include, but are not limited to:

1)         Identification, type (e.g., lean-burn, gas-fired), and location of each unit.

2)         Calendar date of the record.

3)         Before July 1, 2025, the number of hours the unit operated on a monthly basis and during each ozone season.  On and after July 1, 2025, daily operating hours.

B)        Provide a testing protocol to the Agency 60 days prior to testing; and

C)        Not later than 30 days after the completion of the test, submit the results of the test to the Agency.

D)        Notwithstanding subsections (c)(1)(A) through (C), 40 CFR Part 75 affected sources may provide testing notification and protocol submittal in accordance with 40 CFR 75.61(a)(1) and (5) and report in accordance with 40 CFR 75.60(b)(7) requirements.

2)         Under the requirements for monitoring in Section 217.394(e), the owner or operator of the unit must report to the Agency any monitored exceedances of the applicable NO_x concentration from Section 217.388(a)(1) or (a)(2) within 30 days after performing the monitoring.

3)         Within 90 days after permanently shutting down an affected unit or a unit included in an emissions averaging plan, the owner or operator of the unit must withdraw or amend the applicable permit to reflect that the unit is no longer in service.

4)         Until July 1, 2025, if demonstrating compliance through an emissions averaging plan:

A)        By October 31 following the applicable ozone season, the owner or operator must notify the Agency if he or she cannot demonstrate compliance for that ozone season; and

B)        By January 31 following the applicable calendar year, the owner or operator must submit to the Agency a report that demonstrates the following:

i)          For all units that are part of the emissions averaging plan, the total mass of allowable NO_x emissions for the ozone season and for the annual control period;

ii)         The total mass of actual NO_x emissions for the ozone season and annual control period for each unit included in the averaging plan;

iii)        The calculations that demonstrate that the total mass of actual NO_x emissions are less than the total mass of allowable NO_x emissions using equations in Sections 217.390(h) and (i); and

iv)        The information required to determine the total mass of actual NO_x emissions and the calculations performed in subsection (c)(4)(B)(iii) of this Section.

5)         On and after July 1, 2025, if demonstrating compliance through an emissions averaging plan, by May 1 following the previous calendar year, the owner or operator must submit to the Agency a report that includes the following:

A)        For all units that are part of the emissions averaging plan, the total mass of allowable NO_x emissions on a 30-day rolling average basis.

B)        The total mass of actual NO_x emissions on a 30-day rolling average basis for each unit included in the averaging plan.
