                   Subpart I--Individual Unit Opt-ins
 
Sec. 96.87  Change in regulatory status.

    (a) Notification. When a NOX Budget opt-in source becomes 
a NOX Budget unit under Sec. 96.4, the NOX 
authorized account representative shall notify in writing the permitting 
authority and the Administrator of such change in the NOX 
Budget opt-in source's regulatory status, within 30 days of such change.
    (b) Permitting authority's and Administrator's action. (1)(i) When 
the NOX Budget opt-in source becomes a NOX Budget 
unit under Sec. 96.4, the permitting authority will revise the 
NOX Budget opt-in source's NOX Budget opt-in 
permit to meet the requirements of a NOX Budget permit under 
Sec. 96.23 as of an effective date that is the date on which such 
NOX Budget opt-in source becomes a NOX Budget unit 
under Sec. 96.4.
    (ii)(A) The Administrator will deduct from the compliance account 
for the NOX Budget unit under paragraph (b)(1)(i) of this 
section, or the overdraft account of the NOX Budget source 
where the unit is located, NOX allowances equal in number to 
and allocated for the same or a prior control period as:
    (1) Any NOX allowances allocated to the NOX 
Budget unit (as a NOX Budget opt-in source) under Sec. 96.88 
for any control period after the last control period during which the 
unit's NOX Budget opt-in permit was effective; and
    (2) If the effective date of the NOX Budget permit 
revision under paragraph (b)(1)(i) of this section is during a control 
period, the NOX allowances allocated to the NOX 
Budget unit (as a NOX Budget opt-in source) under Sec. 96.88 
for the control period multiplied by the ratio of the number of days, in 
the control period, starting with the effective date of the permit 
revision under paragraph (b)(1)(i) of this section, divided by the total 
number of days in the control period.
    (B) The NOX authorized account representative shall 
ensure that the compliance account of the NOX Budget unit 
under paragraph (b)(1)(i) of this section, or the overdraft account of 
the NOX Budget source where the unit is located, includes the 
NOX allowances necessary for completion of the deduction 
under paragraph (b)(1)(ii)(A) of this section. If the compliance account 
or overdraft account does not contain sufficient NOX 
allowances, the Administrator will deduct the required number of 
NOX allowances, regardless of the control period for which 
they were allocated, whenever NOX allowances are recorded in 
either account.
    (iii)(A) For every control period during which the NOX 
Budget permit revised under paragraph (b)(1)(i) of this section is 
effective, the NOX Budget unit under paragraph (b)(1)(i) of 
this section will be treated, solely for purposes of NOX 
allowance allocations under Sec. 96.42, as a unit that commenced 
operation on the effective date of the NOX Budget permit 
revision under paragraph (b)(1)(i) of this section and

will be allocated NOX allowances under Sec. 96.42.
    (B) Notwithstanding paragraph (b)(1)(iii)(A) of this section, if the 
effective date of the NOX Budget permit revision under 
paragraph (b)(1)(i) of this section is during a control period, the 
following number of NOX allowances will be allocated to the 
NOX Budget unit under paragraph (b)(1)(i) of this section 
under Sec. 96.42 for the control period: the number of NOX 
allowances otherwise allocated to the NOX Budget unit under 
Sec. 96.42 for the control period multiplied by the ratio of the number 
of days, in the control period, starting with the effective date of the 
permit revision under paragraph (b)(1)(i) of this section, divided by 
the total number of days in the control period.
    (2)(i) When the NOX authorized account representative of 
a NOX Budget opt-in source does not renew its NOX 
Budget opt-in permit under Sec. 96.83(b), the Administrator will deduct 
from the NOX Budget opt-in unit's compliance account, or the 
overdraft account of the NOX Budget source where the 
NOX Budget opt-in source is located, NOX 
allowances equal in number to and allocated for the same or a prior 
control period as any NOX allowances allocated to the 
NOX Budget opt-in source under Sec. 96.88 for any control 
period after the last control period for which the NOX Budget 
opt-in permit is effective. The NOX authorized account 
representative shall ensure that the NOX Budget opt-in 
source's compliance account or the overdraft account of the 
NOX Budget source where the NOX Budget opt-in 
source is located includes the NOX allowances necessary for 
completion of such deduction. If the compliance account or overdraft 
account does not contain sufficient NOX allowances, the 
Administrator will deduct the required number of NOX 
allowances, regardless of the control period for which they were 
allocated, whenever NOX allowances are recorded in either 
account.
    (ii) After the deduction under paragraph (b)(2)(i) of this section 
is completed, the Administrator will close the NOX Budget 
opt-in source's compliance account. If any NOX allowances 
remain in the compliance account after completion of such deduction and 
any deduction under Sec. 96.54, the Administrator will close the 
NOX Budget opt-in source's compliance account and will 
establish, and transfer any remaining allowances to, a new general 
account for the owners and operators of the NOX Budget opt-in 
source. The NOX authorized account representative for the 
NOX Budget opt-in source shall become the NOX 
authorized account representative for the general account.
