quarterly NOX mass emissions, as determined under paragraph
(c)(4)(ii)(B) of this section, for all of the calendar quarters in the
year to date.
    (iii) CO2 Mass Emissions. (A) The hourly CO2
mass emissions (tons) for the affected low mass emission unit shall be
determined using Equation LM-11 and the appropriate fuel-based
CO2 emission factor from Table 3 of this section for the
fuel being combusted in that hour. If more than one fuel is combusted
in the hour, use the highest emission factor for all of the fuels
combusted in the hour. If records are missing as to which fuel was
combusted in the hour, use the highest emission factor for all of the
fuels capable of being combusted in the unit.

WCO2 = EFCO2  x  HIhr    (Eq. LM-11)

Where:

WCO2 = Hourly CO  mass emissions (tons).
EFCO2 = Fuel-based CO2 emission factor from Table
3 of this section (ton/mmBtu).
HIhr = Either the maximum rated hourly heat input from
paragraph (c)(3)(i)(A) of this section or the hourly heat input as
determined under paragraph (c)(3)(ii) of this section (mmBtu).

    (B) The quarterly CO2 mass emissions (tons) for the low
mass emission unit shall be the sum of all of the hourly CO2
mass emissions in the quarter, as determined under paragraph
(c)(4)(iii)(A)of this section.
    (C) The year-to-date cumulative CO2 mass emissions
(tons) for the low mass emission unit shall be the sum of all of the
quarterly CO2 mass emissions, as determined under paragraph
(c)(4)(iii)(B) of this section, for all of the calendar quarters in the
year to date.
    (d) Each unit that qualifies under this section to use the low mass
emissions methodology must follow the recordkeeping and reporting
requirements pertaining to low mass emissions units in subparts F and G
of this part.
    (e) The quality control and quality assurance requirements in
Sec. 75.21 are not applicable to a low mass emissions unit for which
the low mass emissions excepted methodology under paragraph (c) of this
section is being used in lieu of a continuous emission monitoring
system or an excepted monitoring system under appendix D or E to this
part, except for fuel flowmeters used to meet the provisions in
paragraph (c)(3)(ii) of this section. However, the owner or operator of
a low mass emissions unit shall implement the following quality
assurance and quality control provisions:
    (1) For low mass emission units or groups of units which use the
long term fuel flow methodology under paragraph (c)(3)(ii) of this
section and which use fuel billing records to determine fuel usage, the
owner or operator shall keep, at the facility, for three years, the
records of the fuel billing statements used for long term fuel flow
determinations.
    (2) For low mass emission units or groups of units which use the

    13. Section 75.20 is amended by adding new paragraph (h) to read as
follows:

Sec. 75.20  Certification and recertification procedures.

* * * * *
    (h) Initial certification and recertification procedures for low
mass emission units using the excepted methodologies under Sec. 75.19.
The owner or operator of a gas-fired or oil-fired unit using the low
mass emissions excepted methodology under Sec. 75.19 shall meet the
applicable general operating requirements of Sec. 75.10, the applicable
requirements of Sec. 75.19, and the applicable certification
requirements of this paragraph.
    (1) Monitoring plan. The designated representative shall submit a
monitoring plan in accordance with Secs. 75.53 and 75.62. The
designated representative for an owner or operator who wishes to use
fuel-and unit-specific NOX emission rate testing for units
with NOX controls under Sec. 75.19(c)(1)(iv) must submit in
the monitoring plan the parameters monitored which will be used to
determine operation of the NOX emission controls. For units
using water or steam injection to control NOX, the water-to-
fuel or steam-to-fuel range of values must be documented.
    (2) Certification application. [reserved]
    (3) Approval of certification applications. The provisions for the
certification application formal approval process in the introductory
text of paragraph (a)(4) and in paragraphs (a)(4)(i), (ii), and (iv) of
this section shall apply, except that ``continuous emission or opacity
monitoring system'' shall be replaced with ``excepted methodology.''
The excepted methodology shall be deemed provisionally certified for
use under the Acid Rain Program, as of the following dates:
    (i) For a unit that commenced operation on or before January 1,
1997, from January 1 of the year following submission of the
certification application until the completion of the period for the
Administrator's review; or
    (ii) For a unit that commenced operation after January 1, 1997,
from the date of submission of a certification application for approval
to use the low mass emissions excepted methodology under Sec. 75.19
until the completion of the period for the Administrator's review,
except that the methodology may be used retrospectively until the date
and hour that the unit commenced operation for purposes of
demonstrating that the unit qualified to use the methodology under
Sec. 75.19(b)(4)(iii).
    (4) Disapproval of certification applications. If the Administrator
determines that the certification application does not demonstrate that
the unit meets the requirements of Secs. 75.19(a) and (b), the
Administrator shall issue a written notice of disapproval of the
certification application within 120 days of receipt. By issuing the
notice of disapproval, the provisional certification is invalidated by
the Administrator, and the data recorded under the excepted methodology
shall not be considered valid. The owner or operator shall follow the
procedures for loss of certification:
    (i) The owner or operator shall substitute the following values, as
applicable, for each hour of unit operation during the period of
invalid data specified in paragraph (a)(4)(iii) of this section or in
Secs. 75.21(e) (introductory paragraph) and 75.21(e)(1): the maximum
potential concentration of SO2, as defined in section
2.1.1.1 of appendix A to this part to report SO2
concentration; the maximum potential NOX emission rate, as
defined in Sec. 72.2 of this chapter to report NOX emission
rate; the maximum potential flow rate, as defined in section 2.1 of
appendix A to this part to report volumetric flow; or the maximum
CO2 concentration used to determine the maximum potential
concentration of SO2 in section 2.1.1.1 of appendix A to
this part to report CO2 concentration data. For a unit
subject to a State or federal NOX mass reduction program
where the owner or operator intends to monitor NOX mass
emissions with a NOX pollutant concentration monitor and a
flow monitoring system, substitute for NOX concentration
using the maximum potential concentration of NOX, as defined
in section 2.1.2.1 of appendix A to this part, and substitute for
volumetric flow using the maximum potential flow rate, as defined in
section 2.1 of appendix A to this part. The owner or operator shall
substitute these values until such time, date, and hour as a continuous
emission monitoring system or excepted monitoring system, where
applicable, is installed and provisionally certified;
    (ii) The designated representative shall submit a notification of
certification test dates, as specified in Sec. 75.61(a)(1)(ii), and a
new certification application according to the procedures in paragraph
(a)(2) of this section; and
    (iii) The owner or operator shall install and provisionally certify
continuous emission monitoring systems or excepted monitoring systems,
where applicable, two calendar quarters from the end of the quarter in
which the unit no longer qualifies as a low mass emissions unit.
    14. Section 75.24 is amended by revising paragraph (d) to read as
follows:

Sec. 75.24  Out-of-control periods.

* * * * *
    (d) When the bias test indicates that an SO2 monitor, a
volumetric flow monitor, a NOX continuous emission
monitoring system or a NOX concentration monitoring system
used to determine NOX mass emissions, as defined in
Sec. 75.71(a)(2), is biased low (i.e., the arithmetic mean of the
differences between the reference method value and the monitor or
monitoring system measurements in a relative accuracy test audit exceed
the bias statistic in section 7 of appendix A to this part), the owner
or operator shall adjust the monitor or continuous emission monitoring
system to eliminate the cause of bias such that it passes the bias
test, or calculate and use the bias adjustment factor as specified in
section 2.3.3 of appendix B to this part and in accordance with Sec. 75.7.
* * * * *
    16. Subpart H is added to part 75 to read as follows:

requirements established by an applicable State or federal
NOX mass emission reduction program that adopts the
requirements of this subpart.
    (3)(i) The designated representative of an affected unit that is
not subject to an Acid Rain emissions limitation may submit a petition
to the permitting authority and the Administrator requesting an
alternative to any requirement of this subpart. Such a petition shall
meet the requirements of Sec. 75.66 and any additional requirements
established by an applicable State or federal NOX mass
emission reduction program that adopts the requirements of this subpart.
    (ii) Use of an alternative to any requirement of this subpart is in
accordance with this subpart only to the extent that it is approved by
the Administrator and by the permitting authority if required by an
applicable State or federal NOX mass emission reduction
program that adopts the requirements of this subpart.

Sec. 75.71  Specific provisions for monitoring NOX emission
rate and heat input for the purpose of calculating NOX mass
emissions.

    (a) Coal-fired units. The owner or operator of a coal-fired
affected unit shall either:

[[Page 57509]]

    (1) Meet the general operating requirements in Sec. 75.10 for a
NOX-diluent continuous emission monitoring system
(consisting of a NOX pollutant concentration monitor, an
O2- or CO2-diluent gas monitor, and a data
acquisition and handling system) to measure NOX emission
rate and for a flow monitoring system and an O2- or
CO2-diluent gas monitor to measure heat input, except as
provided in accordance with subpart E of this part; or
    (2) Meet the general operating requirements in Sec. 75.10 for a
NOX concentration monitoring system (consisting of a
NOX pollutant concentration monitor and a data acquisition
and handling system) to measure NOX concentration and for a

reported under the applicable State or federal NOX mass
emission reduction program that adopts the requirements of this
subpart, the owner or operator also must meet the general operating
requirements for a flow monitoring system and an O2- or
CO2-diluent gas monitor to measure heat input, or, if
applicable, use the procedures in appendix D to this part. These
requirements must be met, except as provided in accordance with subpart
E of this part.
    (b) Moisture correction. If a correction for the stack gas moisture
content is needed to properly calculate the NOX emission
rate in lb/mmBtu (i.e., if the NOX pollutant concentration
monitor measures on a different moisture basis from the diluent
monitor) or NOX mass emissions in tons (i.e., if the
NOX concentration monitoring system or diluent monitor
measures on a different moisture basis from the flow rate monitor), the
owner or operator of an affected unit shall account for the moisture
content of the flue gas on a continuous basis in accordance with
Sec. 75.11(b) except that the term ``SO2'' shall be replaced
by the term ``NOX'.
    (c) Gas-fired nonpeaking units or oil-fired nonpeaking units. The
owner or operator of an affected unit that, based on information
submitted by the designated representative in the monitoring plan,
qualifies as a gas-fired or oil-fired unit but not as a peaking unit,
as defined in Sec. 72.2 of this chapter, shall either:
    (1) Meet the requirements of paragraph (a) of this section and, if
applicable, paragraph (b) of this section; or
    (2) Meet the general operating requirements in Sec. 75.10 for a
NOX-diluent continuous emission monitoring system, except as
provided in accordance with subpart E of this part, and use the
procedures specified in appendix D to this part for determining hourly
heat input. However, the heat input apportionment provisions in section
2.1.2 of appendix D to this part shall not be used to meet the
NOX mass reporting provisions of this subpart, except as
provided in Sec. 75.72(a); or
    (3) Meet the requirements of the low mass emission excepted
methodology under paragraph (e)(2) of this section and under
Sec. 75.19, if applicable.
    (d) Gas-fired or oil-fired peaking units. The owner or operator of
an affected unit that qualifies as a peaking unit and as either gas-
fired or oil-fired, as defined in Sec. 72.2 of this chapter, based on
information submitted by the designated representative in the
monitoring plan, shall either:
    (1) Meet the requirements of paragraph (c) of this section; or
    (2) Use the procedures in appendix D to this part for determining
hourly heat input and the procedures specified in appendix E to this
part for estimating hourly NOX emission rate. However, the
heat input apportionment provisions in section 2.1.2 of appendix D to
this part shall not be used to meet the NOX mass reporting
provisions of this subpart except for units using an excepted
monitoring system under appendix E to this part and except as provided
in Sec. 75.72(a). In addition, if after certification of an excepted
monitoring system under appendix E to this part, a unit's operations
exceed a capacity factor of 20.0 percent in any calender year or exceed
a capacity factor of 10.0 percent averaged over three years, the owner
or operator shall meet the requirements of paragraph (c) of this
section or, if applicable, paragraph (e) of this section, by no later
than December 31 of the following calender year.
    (e) Low mass emissions units. Notwithstanding the requirements of
paragraphs (c) and (d) of this section, the owner or operator of an
affected unit that qualifies as a low mass emissions unit under
Sec. 75.19(a) shall comply with one of the following:
    (1) Meet the applicable requirements specified in paragraphs (c) or
(d) of this section; or
    (2) Use the low mass emissions excepted methodology in
Sec. 75.19(c) for estimating hourly emission rate, hourly heat input,
and hourly NOX mass emissions.
    (f) Other units. The owner or operator of an affected unit that
combusts wood, refuse, or other materials shall comply with the
monitoring provisions specified in paragraph (a) of this section and,
where applicable, paragraph (b) of this section.

Sec. 75.72  Determination of NOX mass emissions.

    Except as provided in paragraphs (e) and (f) of this section, the
owner or operator of an affected unit shall calculate hourly
NOX mass emissions (in lbs) by multiplying the hourly
NOX emission rate (in lbs/mmBtu) by the hourly heat input
(in mmBtu/hr) and the hourly operating time (in hr). The owner or
operator shall also calculate quarterly and cumulative year-to-date
NOX mass emissions and cumulative NOX mass
emissions for the ozone season (in tons) by summing the hourly
NOX mass emissions according to the procedures in section 8
of appendix F to this part.
    (a) Unit utilizing common stack with other affected unit(s). When
an affected unit utilizes a common stack with one or more affected
units, but no nonaffected units, the owner or operator shall either:
    (1) Record the combined NOX mass emissions for the units
exhausting to the common stack, install, certify, operate, and maintain
a NOX-diluent continuous emissions monitoring system in the
common stack, and either:
    (i) Install, certify, operate, and maintain a flow monitoring
system at the common stack. The owner or operator also shall provide
heat input values for each unit, either by monitoring each unit
individually using a flow monitor and a diluent monitor or by
apportioning heat input according to the procedures in
Sec. 75.16(e)(5); or
    (ii) If any of the units using the common stack are eligible to use
the procedures in appendix D to this part,
    (A) Use the procedures in appendix D to this part to determine heat
input for that unit; and
    (B) Install, certify, operate, and maintain a flow monitoring
system in the duct to the common stack for each remaining unit; or
    (2) Install, certify, operate, and maintain a NOX-
diluent continuous emissions monitoring system in the duct to the
common stack from each unit and either:
    (i) Install, certify, operate, and maintain a flow monitoring
system in the duct to the common stack from each unit; or
    (ii) For any unit using the common stack and eligible to use the
procedures in appendix D to this part,
    (A) Use the procedures in appendix D to determine heat input for
that unit; and
    (B) Install, certify, operate, and maintain a flow monitoring
system in the duct to the common stack for each remaining unit.

[[Page 57510]]

    (b) Unit utilizing common stack with nonaffected unit(s). When one
or more affected units utilizes a common stack with one or more
nonaffected units, the owner or operator shall either:
    (1) Install, certify, operate, and maintain a NOX-
diluent continuous emission monitoring system in the duct to the common
stack from each affected unit; and
    (i) Install, certify, operate, and maintain a flow monitoring
system in the duct to the common stack from each affected unit; or
    (ii) For any affected unit using the common stack and eligible to
use the procedures in appendix D to this part,
    (A) Use the procedures in appendix D to determine heat input for
that unit; however, the heat input apportionment provisions in section
2.1.2 of appendix D to this part shall not be used to meet the
NOX mass reporting provisions of this subpart; and
    (B) Install, certify, operate, and maintain a flow monitoring
system in the duct to the common stack for each remaining affected unit
that exhausts to the common stack; or
    (2) Install, certify, operate, and maintain a NOX-
diluent continuous emission monitoring system in the common stack; and
    (i) Designate the nonaffected units as affected units in accordance
with the applicable State or federal NOX mass emissions
reduction program and meet the requirements of paragraph (a)(1) of this
section; or
    (ii) Install, certify, operate, and maintain a flow monitoring
system in the common stack and a NOX-diluent continuous
emission monitoring system in the duct to the common stack from each
nonaffected unit. The designated representative shall submit a petition
to the permitting authority and the Administrator to allow a method of
calculating and reporting the NOX mass emissions from the
affected units as the difference between NOX mass emissions
measured in the common stack and NOX mass emissions measured
in the ducts of the nonaffected units, not to be reported as an hourly
value less than zero. The permitting authority and the Administrator
may approve such a method whenever the designated representative
demonstrates, to the satisfaction of the permitting authority and the
Administrator, that the method ensures that the NOX mass
emissions from the affected units are not underestimated. In addition,
the owner or operator shall also either:
    (A) Install, certify, operate, and maintain a flow monitoring
system in the duct from each nonaffected unit or,
    (B) For any nonaffected unit exhausting to the common stack and
otherwise eligible to use the procedures in appendix D to this part,
determine heat input using the procedures in appendix D for that unit.
However, the heat input apportionment provisions in section 2.1.2 of
appendix D to this part shall not be used to meet the NOX
mass reporting provisions of this subpart. For any remaining
nonaffected unit that exhausts to the common stack, install, certify,
operate, and maintain a flow monitoring system in the duct to the
common stack; or
    (iii) Install a flow monitoring system in the common stack and
record the combined emissions from all units as the combined
NOX mass emissions for the affected units for recordkeeping
and compliance purposes; or
    (iv) Submit a petition to the permitting authority and the
Administrator to allow use of a method for apportioning NOX
mass emissions measured in the common stack to each of the units using
the common stack and for reporting the NOX mass emissions.
The permitting authority and the Administrator may approve such a
method whenever the designated representative demonstrates, to the
satisfaction of the permitting authority and the Administrator, that
the method ensures that the NOX mass emissions from the
affected units are not underestimated.
    (c) Unit with bypass stack. Whenever any portion of the flue gases
from an affected unit can be routed to avoid the installed
NOX-diluent continuous emissions monitoring system or
NOX concentration monitoring system, the owner and operator
shall either:
    (1) Install, certify, operate, and maintain a NOX-
diluent continuous emissions monitoring system and a flow monitoring
system on the bypass flue, duct, or stack gas stream and calculate
NOX mass emissions for the unit as the sum of the emissions
recorded by all required monitoring systems; or
    (2) Monitor NOX mass emissions on the bypass flue, duct,
or stack gas stream using the reference methods in Sec. 75.22(b) for
NOX concentration, flow, and diluent, or NOX
concentration and flow, and calculate NOX mass emissions for
the unit as the sum of the emissions recorded by the installed
monitoring systems on the main stack and the emissions measured by the
reference method monitoring systems.
    (d) Unit with multiple stacks. Notwithstanding Sec. 75.17(c), when
the flue gases from a affected unit discharge to the atmosphere through
more than one stack, or when the flue gases from a unit subject to a
NOX mass emission reduction program utilize two or more
ducts feeding into two or more stacks (which may include flue gases
from other affected or nonaffected unit(s)), or when the flue gases
from an affected unit utilize two or more ducts feeding into a single
stack and the owner or operator chooses to monitor in the ducts rather
than in the stack, the owner or operator shall either:
    (1) Install, certify, operate, and maintain a NOX-
diluent continuous emission monitoring system and a flow monitoring
system in each duct feeding into the stack or stacks and determine
NOX mass emissions from each affected unit using the stack
or stacks as the sum of the NOX mass emissions recorded for
each duct; or
    (2) Install, certify, operate, and maintain a NOX-
diluent continuous emissions monitoring system and a flow monitoring
system in each stack, and determine NOX mass emissions from
the affected unit using the sum of the NOX mass emissions
recorded for each stack, except that where another unit also exhausts
flue gases to one or more of the stacks, the owner or operator shall
also comply with the applicable requirements of paragraphs (a) and (b)
of this section to determine and record NOX mass emissions
from the units using that stack; or
    (3) If the unit is eligible to use the procedures in appendix D to
this part, install, certify, operate, and maintain a NOX-
diluent continuous emissions monitoring system in one of the ducts
feeding into the stack or stacks and use the procedures in appendix D
to this part to determine heat input for the unit, provided that:
    (i) There are no add-on NOX controls at the unit;
    (ii) The unit is not capable of emitting solely through an
unmonitored stack (e.g., has no dampers); and
    (iii) The owner or operator of the unit demonstrates to the
satisfaction of the permitting authority and the Administrator that the
NOX emission rate in the monitored duct or stack is
representative of the NOX emission rate in each duct or stack.
    (e) Units using a NOX concentration monitoring system
and a flow monitoring system to determine NOX mass. The
owner or operator may use a NOX concentration monitoring
system and a flow monitoring system to determine NOX mass
emissions in paragraphs (a) through (d) of this section (in place of a
NOX-diluent continuous emission monitoring system and a flow
monitoring system). When using this approach, calculate NOX
mass according to sections 8.2 and 8.3 in appendix F of this part. In
addition, if an applicable

[[Page 57511]]

State or federal NOX mass reduction program requires
determination of a unit's heat input, the owner or operator must either:
    (1) Install, certify, operate, and maintain a CO2 or
O2 diluent monitor in the same location as each flow
monitoring system. In addition, the owner or operator must provide heat
input values for each unit utilizing a common stack by either:
    (i) Apportion heat input from the common stack to each unit
according to Sec. 75.16(e)(5), where all units utilizing the common
stack are affected units, or
    (ii) Measure heat input from each affected unit, using a flow
monitor and a CO2 or O2 diluent monitor in the
duct from each affected unit; or
    (2) For units that are eligible to use appendix D to this part, use
the procedures in appendix D to this part to determine heat input for
the unit. However, the use of a fuel flowmeter in a common pipe header
and the provisions of sections 2.1.2.1 and 2.1.2.2 of appendix D of
this part are not applicable to any unit that is using the provisions
of this subpart to monitor, record, and report NOX mass
emissions under a State or federal NOX mass emission
reduction program and that shares a common pipe or a common stack with
a nonaffected unit.
    (f) Units using the low mass emitter excepted methodology under
Sec. 75.19. For units that are using the low mass emitter excepted
methodology under Sec. 75.19, calculate ozone season NOX
mass emissions by summing all of the hourly NOX mass
emissions in the ozone season, as determined under paragraph
Sec. 75.19(c)(4)(ii)(A) of this section, divided by 2000 lb/ton.
    (g) Procedures for apportioning heat input to the unit level. If
the owner or operator of a unit using the common stack monitoring
provisions in paragraphs (a) or (b) of this section does not monitor
and record heat input at the unit level and the owner or operator is
required to do so under an applicable State or federal NOX
mass emission reduction program, the owner or operator should apportion
heat input from the common stack to each unit according to Sec. 75.16(e)(5).

Sec. 75.73 Recordkeeping and reporting.  [Reserved]


Sec. 75.74  Annual and ozone season monitoring and reporting requirements.

    (a) Annual monitoring requirement. (1) The owner or operator of an
affected unit subject both to an Acid Rain emission limitation and to a
State or federal NOX mass reduction program that adopts the
provisions of this part must meet the requirements of this part during
the entire calendar year.
    (2) The owner or operator of an affected unit subject to a State or
federal NOX mass reduction program that adopts the
provisions of this part and that requires monitoring and reporting of
hourly emissions on an annual basis must meet the requirements of this
part during the entire calendar year.
    (b) Ozone season monitoring requirements. The owner or operator of
an affected unit that is not required to meet the requirements of this
subpart on an annual basis under paragraph (a) of this section may either:
    (1) Meet the requirements of this subpart on an annual basis; or
    (2) Meet the requirements of this part during the ozone season,
except as specified in paragraph (c) of this section.
    (c) If the owner or operator of an affected unit chooses to meet
the requirements of this subpart on less than an annual basis in
accordance with paragraph (b)(2) of this section, then:
    (1) The owner or operator of a unit that uses continuous emissions
monitoring systems to meet any of the requirements of this subpart must
perform recertification testing of all continuous emission monitoring
systems under Sec. 75.20(b). If the owner or operator has not
successfully completed all recertification tests by the first hour of
unit operation during the ozone season each year, the owner or operator
must substitute for data following the procedures of Sec. 75.20(b).
    (2) The owner or operator is required to operate and maintain
continuous emission monitoring systems and perform quality assurance
and quality control procedures under Sec. 75.21 and appendix B of this
part each year from the time the continuous emission monitoring system
is initially certified or is recertified under paragraph (c)(1) of this
section through September 30. Records related to the quality assurance/
quality control program must be kept in a form suitable for inspection
on a year-round basis.
    (3) The owner or operator of a unit using the procedures in
appendix D of this part to determine heat input is required to operate
or maintain fuel flowmeters only during the ozone season, except that
for purposes of determining the deadline for the next periodic quality
assurance test on the fuel flowmeter, the owner or operator shall count
all quarters during the year when the fuel flowmeter is used, not just
quarters in the ozone season. The owner or operator shall record and
the designated representative shall report the number of quarters when
a fuel is combusted for each fuel flowmeter.
    (4) The owner or operator of a unit using the procedures in
appendix D of this part to determine heat input is only required to
sample fuel during the ozone season, except that:
    (i) The owner or operator of a diesel-fired unit that performs
sampling from the fuel storage tank upon delivery must sample the tank
between the date and hour of the most recent delivery before the first
date and hour that the unit operates in the ozone season and the first
date and hour that the unit operates in the ozone season.
    (ii) The owner or operator of a diesel-fired unit that performs
sampling upon delivery from the delivery vehicle must ensure that all
shipments received during the calendar year are sampled.
    (iii) The owner or operator of a unit that performs sampling on
each day the unit combusts fuel oil or that performs oil sampling
continuously must sample the fuel oil starting on the first day the
unit operates during the ozone season. The owner or operator then shall
use that sampled value for all hours of combustion during the first day
of unit operation, continuing until the date and hour of the next sample.
    (5) The owner or operator is required to record and report the
hourly data required by this subpart for the longer of:
    (i) The period of time that the owner or operator of the unit is
required to perform the quality assurance and quality control
procedures of Sec. 75.21 and appendix B of this part under paragraph
(c)(2) of this section; or
    (ii) The period of time of May 1 through September 30.
    (6) The owner or operator shall use quality-assured data, in
accordance with paragraph (c)(2) or (c)(3) of this section, in the
substitute data procedures under subpart D of this part and section 2.4
of appendix D of this part.
    (i) The lookback periods (e.g., 2160 quality-assured monitor
operating hours for a NOX-diluent continuous emission
monitoring system, a NOX concentration monitoring system, or
a flow monitoring system) used to calculate missing data must include
only data from periods when the monitors were quality assured under
paragraph (c)(2) or (c)(3) of this section.
    (ii) If the NOX emission rate or NOX
concentration of the unit was consistently lower in the previous ozone
season because the unit combusted a fuel that produces less
NOX than the fuel currently being combusted or because the
unit's add-on emission controls are not operating properly, then the
owner or operator shall not use the

[[Page 57512]]

missing data procedures of Secs. 75.31 through 75.33. Instead, the
owner or operator shall substitute the maximum potential NOX
emission rate, as defined in Sec. 72.2 of this chapter, from a
NOX-diluent continuous emission monitoring system, or the
maximum potential concentration of NOX, as defined in
section 2.1.2.1 of appendix A to this part, from a NOX
concentration monitoring system. The owner or operator shall substitute
these maximum potential values for each hour of missing NOX
data, from completion of recertification testing until the earliest of:
    (A) 720 quality-assured monitor operating hours after the
completion of recertification testing (not to go beyond September 30 of
that ozone season), or
    (B) For a unit that changed fuels, the first hour when the unit
combusts a fuel that produces the same or less NOX than the
fuel combusted in the previous ozone season, or
    (C) For a unit with add-on emission controls that are not operating
properly, the first hour when the add-on emission controls operate
properly.
    (7) The owner or operator of a unit with NOX add-on
emission controls or a unit capable of combusting more than one fuel
shall keep records during ozone season in a form suitable for
inspection to demonstrate that the typical NOX emission rate
or NOX concentration during the prior ozone season(s)
included in the missing data lookback period is representative of the
ozone season in which missing data are substituted and that use of the
missing data procedures will not systematically underestimate
NOX mass emissions. These records shall include:
    (i) For units that can combust more than one fuel, the fuel or
fuels combusted each hour; and
    (ii) For units with add-on emission controls, the range of
operating parameters for add-on emission controls, as described in
Sec. 75.34(a) and information for verifying proper operation of the
add-on emission controls, as described in Sec. 75.34(d).
    (8) The designated representative shall certify with each quarterly
report that NOX emission rate values or NOX
concentration values substituted for missing data under subpart D of
this part are calculated using only values from an ozone season, that
substitute values measured during the prior ozone season(s) included in
the missing data lookback period are representative of the ozone season
in which missing data are substituted, and that NOX
emissions are not systematically underestimated.
    (9) Units may qualify to use the low mass emission excepted
monitoring methodology in Sec. 75.19 on an ozone season basis. In order
to be allowed to use this methodology, a unit may not emit more than 25
tons of NOX per ozone season. The owner or operator of the
unit shall meet the requirements of Sec. 75.19, with the following
exceptions:
    (i) The phrase ``50 tons of NOX annually'' shall be
replaced by the phrase ``25 tons of NOX during the ozone
season.''
    (ii) If any low mass emission unit fails to provide a demonstration
that its ozone season NOX mass emissions are less than 25
tons, than the unit is disqualified from using the methodology. The
owner or operator must install and certify any equipment needed to
ensure that the unit is monitoring using an acceptable methodology by
May 1 of the following year.
    (10) Units may qualify to use the optional NOX mass
emissions estimation protocol for gas-fired peaking units and oil-fired
peaking units in appendix E to this part on an ozone season basis. In
order to be allowed to use this methodology, the unit must meet the
definition of peaking unit in Sec. 72.2 of this part, except that the
word ``calender year'' shall be replaced by the word ``ozone season''
and the word annual in the definition of the term ``capacity factor''
in Sec. 72.2 of this part, shall be replaced by the word ``ozone
season''.

Sec. 75.75  Additional ozone season calculation procedures for special
circumstances.

    (a) The owner or operator of a unit that is required to calculate
ozone season heat input for purposes of providing data needed for
determining allocations, shall do so by summing the unit's hourly heat
input determined according to the procedures in this part for all hours
in which the unit operated during the ozone season.
    (b) The owner or operator of a unit that is required to determine
ozone season NOX emission rate (in lbs/mmBtu) shall do so by
dividing ozone season NOX mass emissions(in lbs) determined
in accordance with this subpart, by heat input determined in accordance
with paragraph (a) of this section.

8. Procedures for NOX Mass Emissions

    The owner or operator of a unit that is required to monitor,
record, and report NOX mass emissions under a State or
federal NOX mass emission reduction program must use the
procedures in section 8.1 to account for hourly NOX mass
emissions, and the procedures in section 8.2 to account for
quarterly, seasonal, and annual NOX mass emissions to the
extent that the provisions of subpart H of this part are adopted as
requirements under such a program.
    8.1  Use the following procedures to calculate hourly
NOX mass emissions in lbs for the hour using hourly
NOX emission rate and heat input.
    8.1.1  If both NOX emission rate and heat input are
monitored at the same unit or stack level (e.g, the NOX
emission rate value and heat input value both represent all of the
units exhausting to the common stack), use the following equation:
[GRAPHIC] [TIFF OMITTED] TR27OC98.011

where:

M(NOx)h = NOX mass emissions in lbs for the
hour.
E(NOx)h = Hourly average NOX emission rate for
hour h, lb/mmBtu, from section 3 of this appendix, from method 19 of
appendix A to part 60 of this chapter, or from section 3.3 of
appendix E to this part. (Include bias-adjusted NOX
emission rate values, where the bias-test procedures in appendix A
to this part shows a bias-adjustment factor is necessary.)
HIh = Hourly average heat input rate for hour h, mmBtu/
hr. (Include bias-adjusted flow rate values, where the bias-test
procedures in appendix A to this part shows a bias-adjustment factor
is necessary.)

[[Page 57514]]

th = Monitoring location operating time for hour h, in
hours or fraction of an hour (in equal increments that can range
from one hundredth to one quarter of an hour, at the option of the
owner or operator). If the combined NOX emission rate and
heat input are monitored for all of the units in a common stack, the
monitoring location operating time is equal to the total time when
any of those units was exhausting through the common stack.

    8.1.2  If NOX emission rate is measured at a common
stack and heat input is measured at the unit level, sum the hourly
heat inputs at the unit level according to the following formula:
[GRAPHIC] [TIFF OMITTED] TR27OC98.012

where:
HICS = Hourly average heat input rate for hour h for the
units at the common stack, mmBtu/hr.
tCS = Common stack operating time for hour h, in hours or
fraction of an hour (in equal increments that can range from one
hundredth to one quarter of an hour, at the option of the owner or
operator)(e.g., total time when any of the units which exhaust
through the common stack are operating).
HIu = Hourly average heat input rate for hour h for the
unit, mmBtu/hr.
tu = Unit operating time for hour h, in hours or fraction
of an hour (in equal increments that can range from one hundredth to
one quarter of an hour, at the option of the owner or operator).
    Use the hourly heat input rate at the common stack level and the
hourly average NOX emission rate at the common stack
level and the procedures in section 8.1.1 of this appendix to
determine the hourly NOX mass emissions at the common stack.
    8.1.3  If a unit has multiple ducts and NOX emission
rate is only measured at one duct, use the NOX emission
rate measured at the duct, the heat input measured for the unit, and
the procedures in section 8.1.1 of this appendix to determine
NOX mass emissions.
    8.1.4  If a unit has multiple ducts and NOX emission
rate is measured in each duct, heat input shall also be measured in
each duct and the procedures in section 8.1.1 of this appendix shall
be used to determine NOX mass emissions.
    8.2  If a unit calculates NOX mass emissions using a
NOX concentration monitoring system and a flow monitoring
system, calculate hourly NOX mass rate during unit (or
stack) operation, in lb/hr, using Equation F-1 or F-2 in this
appendix (as applicable to the moisture basis of the monitors). When
using Equation F-1 or F-2, replace ``SO2'' with
``NOX'' and replace the value of K with 1.194 x
10<SUP>-</SUP><SUP>7</SUP> (lb NOX /scf)/ppm. (Include
bias-adjusted flow rate or NOX concentration values,
where the bias-test procedures in appendix A to this part shows a
bias-adjustment factor is necessary.)
    8.3  If a unit calculates NOX mass emissions using a
NOX concentration monitoring system and a flow monitoring
system, calculate NOX mass emissions for the hour (lb) by
multiplying the hourly NOX mass emission rate during unit
operation (lb/hr) by the unit operating time during the hour, as follows:
[GRAPHIC] [TIFF OMITTED] TR27OC98.013

Where:

M(NOx)h = NOX mass emissions in lbs for the hour.
Eh = Hourly NOX mass emission rate during unit
(or stack) operation, lb/hr, from section 8.2 of this appendix.
th = Monitoring location operating time for hour h, in
hours or fraction of an hour (in equal increments that can range
from one hundredth to one quarter of an hour, at the option of the
owner or operator). If the NOX mass emission rate is
monitored for all of the units in a common stack, the monitoring
location operating time is equal to the total time when any of those
units was exhausting through the common stack.

    8.4  Use the following procedures to calculate quarterly,
cumulative ozone season, and cumulative yearly NOX mass
emissions, in tons:
[GRAPHIC] [TIFF OMITTED] TR27OC98.014

Where:

M(NOx) time period = NOX mass emissions in
tons for the given time period (quarter, cumulative ozone season,
cumulative year-to-date).
M(NOx)h = NOX mass emissions in lbs for the
hour. p = The number of hours in the given time period (quarter,
cumulative ozone season, cumulative year-to-date).

    8.5 Specific provisions for monitoring NOX mass
emissions from common stacks. The owner or operator of a unit
utilizing a common stack may account for NOX mass
emissions using either of the following methodologies, if the
provisions of subpart H are adopted as requirements of a State or
federal NOX mass reduction program:
    8.5.1  The owner or operator may determine both NOX
emission rate and heat input at the common stack and use the
procedures in section 8.1.1 of this appendix to determine hourly
NOX mass emissions at the common stack.
    8.5.2  The owner or operator may determine the NOX
emission rate at the common stack and the heat input at each of the
units and use the procedures in section 8.1.2 of this appendix to
determine the hourly NOX mass emissions at each unit.

Sec. 96.4  Applicability.

    (a) The following units in a State shall be NOX Budget
units, and any source that includes one or more such units shall be a
NOX Budget source, subject to the requirements of this part:
    (1) Any unit that, any time on or after January 1, 1995, serves a
generator with a nameplate capacity greater than 25 MWe and sells any
amount of electricity; or
    (2) Any unit that is not a unit under paragraph (a) of this section
and that has a maximum design heat input greater than 250 mmBtu/hr.
    (b) Notwithstanding paragraph (a) of this section, a unit under
paragraph (a) of this section shall be subject only to the requirements
of this paragraph (b) if the unit has a federally enforceable permit
that meets the requirements of paragraph (b)(1) of this section and
restricts the unit to burning only natural gas or fuel oil during a
control period in 2003 or later and each control period thereafter and
restricts the unit's operating hours during each such control period to
the number of hours (determined in accordance with paragraph (b)(1)(ii)
and (iii) of this section) that limits the unit's potential
NOX mass emissions for the control period to 25 tons or
less. Notwithstanding paragraph (a) of this section, starting with the
effective date of such federally enforceable permit, the unit shall not
be a NOX Budget unit.
    (1) For each control period under paragraph (b) of this section,
the federally enforceable permit must:
    (i) Restrict the unit to burning only natural gas or fuel oil.
    (ii) Restrict the unit's operating hours to the number calculated
by dividing 25 tons of potential NOX mass emissions by the
unit's maximum potential hourly NOX mass emissions.
    (iii) Require that the unit's potential NOX mass
emissions shall be calculated as follows:
    (A) Select the default NOX emission rate in Table 2 of
Sec. 75.19 of this chapter that would otherwise be applicable assuming
that the unit burns only the type of fuel (i.e., only natural gas or
only fuel oil) that has the highest default NOX emission
factor of any type of fuel that the unit is allowed to burn under the
fuel use restriction in paragraph (b)(1)(i) of this section; and
    (B) Multiply the default NOX emission rate under
paragraph (b)(1)(iii)(A) of this section by the unit's maximum rated
hourly heat input. The owner or operator of the unit may petition the
permitting authority to use a lower value for the unit's maximum rated
hourly heat input than the value as defined under Sec. 96.2. The
permitting authority may approve such lower value if the owner or
operator demonstrates that the maximum hourly heat input specified by
the manufacturer or the highest observed hourly heat input, or both,
are not representative, and that such lower value is representative, of
the unit's current capabilities because

[[Page 57519]]

modifications have been made to the unit, limiting its capacity
permanently.
    (iv) Require that the owner or operator of the unit shall retain at
the source that includes the unit, for 5 years, records demonstrating
that the operating hours restriction, the fuel use restriction, and the
other requirements of the permit related to these restrictions were met.
    (v) Require that the owner or operator of the unit shall report the
unit's hours of operation (treating any partial hour of operation as a
whole hour of operation) during each control period to the permitting
authority by November 1 of each year for which the unit is subject to
the federally enforceable permit.
    (2) The permitting authority that issues the federally enforceable
permit with the fuel use restriction under paragraph (b)(1)(i) and the
operating hours restriction under paragraphs (b)(1)(ii) and (iii) of
this section will notify the Administrator in writing of each unit
under paragraph (a) of this section whose federally enforceable permit
issued by the permitting authority includes such restrictions. The
permitting authority will also notify the Administrator in writing of
each unit under paragraph (a) of this section whose federally
enforceable permit issued by the permitting authority is revised to
remove any such restriction, whose federally enforceable permit issued
by the permitting authority includes any such restriction that is no
longer applicable, or which does not comply with any such restriction.
    (3) If, for any control period under paragraph (b) of this section,
the fuel use restriction under paragraph (b)(1)(i) of this section or
the operating hours restriction under paragraphs (b)(1)(ii) and (iii)
of this section is removed from the unit's federally enforceable permit
or otherwise becomes no longer applicable or if, for any such control
period, the unit does not comply with the fuel use restriction under
paragraph (b)(1)(i) of this section or the operating hours restriction
under paragraphs (b)(1)(ii) and (iii) of this section, the unit shall
be a NOX Budget unit, subject to the requirements of this
part. Such unit shall be treated as commencing operation and, for a
unit under paragraph (a)(1) of this section, commencing commercial
operation on September 30 of the control period for which the fuel use
restriction or the operating hours restriction is no longer applicable
or during which the unit does not comply with the fuel use restriction
or the operating hours restriction.

Sec. 96.42  NOX allowance allocations.

    (a)(1) The heat input (in mmBtu) used for calculating
NOX allowance allocations for each NOX Budget
unit under Sec. 96.4 will be:
    (i) For a NOX allowance allocation under Sec. 96.41(a),
the average of the two highest amounts of the unit's heat input for the
control periods in 1995, 1996, and 1997 if the unit is under
Sec. 96.4(a)(1) or the control period in 1995 if the unit is under
Sec. 96.4(a)(2); and
    (ii) For a NOX allowance allocation under Sec. 96.41(b),
the unit's heat input for the control period in the year that is four
years before the year for which the NOX allocation is being
calculated.
    (2) The unit's total heat input for the control period in each year
specified under paragraph (a)(1) of this section will be determined in
accordance with part 75 of this chapter if the NOX Budget

section, a total number of NOX allowances equal to 95
percent in 2003, 2004, and 2005, or 98 percent thereafter, of the tons
of NOX emissions in the State trading program budget
apportioned to electric generating units under Sec. 96.40 in accordance
with the following procedures:
    (1) The permitting authority will allocate NOX
allowances to each NOX Budget unit under Sec. 96.4(a)(1) in
an amount equaling 0.15 lb/mmBtu multiplied by the heat input
determined under paragraph (a) of this section, rounded to the nearest
whole NOX allowance as appropriate.
    (2) If the initial total number of NOX allowances
allocated to all NOX Budget units under Sec. 96.4(a)(1) in
the State for a control period under paragraph (b)(1) of this section
does not equal 95 percent in 2003, 2004, and 2005, or 98 percent
thereafter, of the number of tons of NOX emissions in the
State trading program

[[Page 57525]]

budget apportioned to electric generating units, the permitting
authority will adjust the total number of NOX allowances
allocated to all such NOX Budget units for the control
period under paragraph (b)(1) of this section so that the total number
of NOX allowances allocated equals 95 percent in 2003, 2004,
and 2005, or 98 percent thereafter, of the number of tons of
NOX emissions in the State trading program budget
apportioned to electric generating units. This adjustment will be made
by: multiplying each unit's allocation by 95 percent in 2003, 2004, and
2005, or 98 percent thereafter, of the number of tons of NOX
emissions in the State trading program budget apportioned to electric
generating units divided by the total number of NOX
allowances allocated under paragraph (b)(1) of this section, and
rounding to the nearest whole NOX allowance as appropriate.
    (c) For each control period under Sec. 96.41, the permitting
authority will allocate to all NOX Budget units under
Sec. 96.4(a)(2) in the State that commenced operation before May 1 of

section, a total number of NOX allowances equal to 95
percent in 2003, 2004, and 2005, or 98 percent thereafter, of the tons
of NOX emissions in the State trading program budget
apportioned to non-electric generating units under Sec. 96.40 in
accordance with the following procedures:
    (1) The permitting authority will allocate NOX
allowances to each NOX Budget unit under Sec. 96.4(a)(2) in
an amount equaling 0.17 lb/mmBtu multiplied by the heat input
determined under paragraph (a) of this section, rounded to the nearest
whole NOX allowance as appropriate.
    (2) If the initial total number of NOX allowances
allocated to all NOX Budget units under Sec. 96.4(a)(2) in
the State for a control period under paragraph (c)(1) of this section
does not equal 95 percent in 2003, 2004, and 2005, or 98 percent
thereafter, of the number of tons of NOX emissions in the
State trading program budget apportioned to non-electric generating
units, the permitting authority will adjust the total number of
NOX allowances allocated to all such NOX Budget
units for the control period under paragraph (c)(1) of this section so
that the total number of NOX allowances allocated equals 95
percent in 2003, 2004, and 2005, or 98 percent thereafter, of the
number of tons of NOX emissions in the State trading program
budget apportioned to non-electric generating units. This adjustment
will be made by: multiplying each unit's allocation by 95 percent in
2003, 2004, and 2005, or 98 percent thereafter, of the number of tons
of NOX emissions in the State trading program budget
apportioned to non-electric generating units divided by the total
number of NOX allowances allocated under paragraph (c)(1) of
this section, and rounding to the nearest whole NOX
allowance as appropriate.
    (d) For each control period under Sec. 96.41, the permitting
authority will allocate NOX allowances to NOX
Budget units under Sec. 96.4 in the State that commenced operation, or
is projected to commence operation, on or after May 1 of the period
used to calculate heat input under paragraph (a)(1) of this section, in
accordance with the following procedures:
    (1) The permitting authority will establish one allocation set-
aside for each control period. Each allocation set-aside will be
allocated NOX allowances equal to 5 percent in 2003, 2004,
and 2005, or 2 percent thereafter, of the tons of NOX
emissions in the State trading program budget under Sec. 96.40, rounded
to the nearest whole NOX allowance as appropriate.
    (2) The NOX authorized account representative of a
NOX Budget unit under paragraph (d) of this section may
submit to the permitting authority a request, in writing or in a format
specified by the permitting authority, to be allocated NOX
allowances for no more than five consecutive control periods under
Sec. 96.41, starting with the control period during which the
NOX Budget unit commenced, or is projected to commence,
operation and ending with the control period preceding the control
period for which it will receive an allocation under paragraph (b) or
(c) of this section. The NOX allowance allocation request
must be submitted prior to May 1 of the first control period for which
the NOX allowance allocation is requested and after the date
on which the permitting authority issues a permit to construct the
NOX Budget unit.
    (3) In a NOX allowance allocation request under
paragraph (d)(2) of this section, the NOX authorized account
representative for units under Sec. 96.4(a)(1) may request for a
control period NOX allowances in an amount that does not
exceed 0.15 lb/mmBtu multiplied by the NOX Budget unit's
maximum design heat input (in mmBtu/hr) multiplied by the number of
hours remaining in the control period starting with the first day in
the control period on which the unit operated or is projected to operate.
    (4) In a NOX allowance allocation request under
paragraph (d)(2) of this section, the NOX authorized account
representative for units under Sec. 96.4(a)(2) may request for a
control period NOX allowances in an amount that does not
exceed 0.17 lb/mmBtu multiplied by the NOX Budget unit's
maximum design heat input (in mmBtu/hr) multiplied by the number of
hours remaining in the control period starting with the first day in
the control period on which the unit operated or is projected to operate.
    (5) The permitting authority will review, and allocate
NOX allowances pursuant to, each NOX allowance
allocation request under paragraph (d)(2) of this section in the order
that the request is received by the permitting authority.
    (i) Upon receipt of the NOX allowance allocation
request, the permitting authority will determine whether, and will make
any necessary adjustments to the request to ensure that, for units
under Sec. 96.4(a)(1), the control period and the number of allowances
specified are consistent with the requirements of paragraphs (d)(2) and
(3) of this section and, for units under Sec. 96.4(a)(2), the control
period and the number of allowances specified are consistent with the
requirements of paragraphs (d)(2) and (4) of this section.
    (ii) If the allocation set-aside for the control period for which
NOX allowances are requested has an amount of NOX
allowances not less than the number requested (as adjusted under
paragraph (d)(5)(i) of this section), the permitting authority will
allocate the amount of the NOX allowances requested (as
adjusted under paragraph (d)(5)(i) of this section) to the
NOX Budget unit.
    (iii) If the allocation set-aside for the control period for which
NOX allowances are requested has a smaller amount of
NOX allowances than the number requested (as adjusted under
paragraph (d)(5)(i) of this section), the permitting authority will
deny in part the request and allocate only the remaining number of
NOX allowances in the allocation set-aside to the
NOX Budget unit.
    (iv) Once an allocation set-aside for a control period has been
depleted of all NOX allowances, the permitting authority
will deny, and will not allocate any NOX allowances pursuant
to, any NOX allowance allocation request under which
NOX allowances have not already been allocated for the
control period.
    (6) Within 60 days of receipt of a NOX allowance
allocation request, the permitting authority will take appropriate
action under paragraph (d)(5) of this section and notify the
NOX authorized account representative that submitted the
request and the Administrator of the number of NOX

[[Page 57526]]

allowances (if any) allocated for the control period to the
NOX Budget unit.
    (e) For a NOX Budget unit that is allocated
NOX allowances under paragraph (d) of this section for a
control period, the Administrator will deduct NOX allowances
under Sec. 96.54(b) or (e) to account for the actual utilization of the
unit during the control period. The Administrator will calculate the
number of NOX allowances to be deducted to account for the
unit's actual utilization using the following formulas and rounding to
the nearest whole NOX allowance as appropriate, provided
that the number of NOX allowances to be deducted shall be
zero if the number calculated is less than zero:

NOX allowances deducted for actual utilization for units
under Sec. 96.4(a)(1) = (Unit's NOX allowances allocated
for control period)-(Unit's actual control period utilization  x
0.15 lb/mmBtu); and
NOX allowances deducted for actual utilization for units
under Sec. 96.4(a)(2) = (Unit's NOX allowances allocated
for control period)-(Unit's actual control period utilization  x
0.17 lb/mmBtu)
Where:

    ``Unit's NOX allowances allocated for control
period'' is the number of NOX allowances allocated to the
unit for the control period under paragraph (d) of this section; and
    ``Unit's actual control period utilization'' is the utilization
(in mmBtu), as defined in Sec. 96.2, of the unit during the control period.

    (f) After making the deductions for compliance under Sec. 96.54(b)
or (e) for a control period, the Administrator will notify the
permitting authority whether any NOX allowances remain in
the allocation set-aside for the control period. The permitting
authority will allocate any such NOX allowances to the
NOX Budget units in the State using the following formula
and rounding to the nearest whole NOX allowance as appropriate:

Unit's share of NOX allowances remaining in allocation
set-aside = Total NOX allowances remaining in allocation
set-aside  x  (Unit's NOX allowance allocation <divide>
(State trading program budget excluding allocation set-aside)
Where:

    ``Total NOX allowances remaining in allocation set-
aside'' is the total number of NOX allowances remaining
in the allocation set-aside for the control period to which the
allocation set-aside applies;
    ``Unit's NOX allowance allocation'' is the number of
NOX allowances allocated under paragraph (b) or (c) of
this section to the unit for the control period to which the
allocation set-aside applies; and
    ``State trading program budget excluding allocation set-aside''
is the State trading program budget under Sec. 96.40 for the control
period to which the allocation set-aside applies multiplied by 95
percent if the control period is in 2003, 2004, or 2005 or 98
percent if the control period is in any year thereafter, rounded to
the nearest whole NOX allowance as appropriate.

representative for a general account, including private legal disputes
concerning the proceeds of NOX allowance transfers.
    (c) Account identification. The Administrator will assign a unique
identifying number to each account established under paragraph (a) or
(b) of this section.

Sec. 96.52  NOX Allowance Tracking System responsibilities
of NOX authorized account representative.

    (a) Following the establishment of a NOX Allowance
Tracking System account, all submissions to the Administrator
pertaining to the account, including, but not limited to, submissions
concerning the deduction or transfer of NOX allowances in
the account, shall be made only by the NOX authorized
account representative for the account.
    (b) Authorized account representative identification. The
Administrator will assign a unique identifying number to each
NOX authorized account representative.

Sec. 96.53  Recordation of NOX allowance allocations.

    (a) The Administrator will record the NOX allowances for
2003 in the NOX Budget units' compliance accounts and the
allocation set-asides, as allocated under subpart E of this part. The
Administrator will also record the NOX allowances allocated
under Sec. 96.88(a)(1) for each NOX Budget opt-in source in
its compliance account.
    (b) Each year, after the Administrator has made all deductions from
a NOX Budget unit's compliance account and the overdraft
account pursuant to Sec. 96.54, the Administrator will record

[[Page 57528]]

NOX allowances, as allocated to the unit under subpart E of
this part or under Sec. 96.88(a)(2), in the compliance account for the
year after the last year for which allowances were previously allocated
to the compliance account. Each year, the Administrator will also
record NOX allowances, as allocated under subpart E of this
part, in the allocation set-aside for the year after the last year for
which allowances were previously allocated to an allocation set-aside.
    (c) Serial numbers for allocated NOX allowances. When
allocating NOX allowances to and recording them in an
account, the Administrator will assign each NOX allowance a
unique identification number that will include digits identifying the
year for which the NOX allowance is allocated.

Sec. 96.54  Compliance.

    (a) NOX allowance transfer deadline. The NOX
allowances are available to be deducted for compliance with a unit's
NOX Budget emissions limitation for a control period in a
given year only if the NOX allowances:
    (1) Were allocated for a control period in a prior year or the same
year; and
    (2) Are held in the unit's compliance account, or the overdraft
account of the source where the unit is located, as of the
NOX allowance transfer deadline for that control period or
are transferred into the compliance account or overdraft account by a
NOX allowance transfer correctly submitted for recordation
under Sec. 96.60 by the NOX allowance transfer deadline for
that control period.
    (b) Deductions for compliance. (1) Following the recordation, in
accordance with Sec. 96.61, of NOX allowance transfers
submitted for recordation in the unit's compliance account or the
overdraft account of the source where the unit is located by the
NOX allowance transfer deadline for a control period, the
Administrator will deduct NOX allowances available under
paragraph (a) of this section to cover the unit's NOX
emissions (as determined in accordance with subpart H of this part), or
to account for actual utilization under Sec. 96.42(e), for the control
period:
    (i) From the compliance account; and
    (ii) Only if no more NOX allowances available under
paragraph (a) of this section remain in the compliance account, from
the overdraft account. In deducting allowances for units at the source
from the overdraft account, the Administrator will begin with the unit
having the compliance account with the lowest NOX Allowance
Tracking System account number and end with the unit having the
compliance account with the highest NOX Allowance Tracking
System account number (with account numbers sorted beginning with the
left-most character and ending with the right-most character and the
letter characters assigned values in alphabetical order and less than
all numeric characters).
    (2) The Administrator will deduct NOX allowances first
under paragraph (b)(1)(i) of this section and then under paragraph
(b)(1)(ii) of this section:
    (i) Until the number of NOX allowances deducted for the
control period equals the number of tons of NOX emissions,
determined in accordance with subpart H of this part, from the unit for
the control period for which compliance is being determined, plus the
number of NOX allowances required for deduction to account
for actual utilization under Sec. 96.42(e) for the control period; or
    (ii) Until no more NOX allowances available under
paragraph (a) of this section remain in the respective account.
    (c)(1) Identification of NOX allowances by serial
number. The NOX authorized account representative for each
compliance account may identify by serial number the NOX
allowances to be deducted from the unit's compliance account under
paragraph (b), (d), or (e) of this section. Such identification shall
be made in the compliance certification report submitted in accordance
with Sec. 96.30.
    (2) First-in, first-out. The Administrator will deduct
NOX allowances for a control period from the compliance
account, in the absence of an identification or in the case of a
partial identification of NOX allowances by serial number
under paragraph (c)(1) of this section, or the overdraft account on a
first-in, first-out (FIFO) accounting basis in the following order:
    (i) Those NOX allowances that were allocated for the
control period to the unit under subpart E or I of this part;
    (ii) Those NOX allowances that were allocated for the
control period to any unit and transferred and recorded in the account
pursuant to subpart G of this part, in order of their date of
recordation;
    (iii) Those NOX allowances that were allocated for a
prior control period to the unit under subpart E or I of this part; and
    (iv) Those NOX allowances that were allocated for a
prior control period to any unit and transferred and recorded in the
account pursuant to subpart G of this part, in order of their date of
recordation.
    (d) Deductions for excess emissions. (1) After making the
deductions for compliance under paragraph (b) of this section, the
Administrator will deduct from the unit's compliance account or the
overdraft account of the source where the unit is located a number of
NOX allowances, allocated for a control period after the
control period in which the unit has excess emissions, equal to three
times the number of the unit's excess emissions.
    (2) 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.
    (3) Any allowance deduction required under paragraph (d) of this
section shall not affect the liability of the owners and operators of
the NOX Budget unit for any fine, penalty, or assessment, or
their obligation to comply with any other remedy, for the same
violation, as ordered under the CAA or applicable State law. The
following guidelines will be followed in assessing fines, penalties or
other obligations:
    (i) For purposes of determining the number of days of violation, if
a NOX Budget unit has excess emissions for a control period,
each day in the control period (153 days) constitutes a day in
violation unless the owners and operators of the unit demonstrate that
a lesser number of days should be considered.
    (ii) Each ton of excess emissions is a separate violation.
    (e) Deductions for units sharing a common stack. In the case of
units sharing a common stack and having emissions that are not
separately monitored or apportioned in accordance with subpart H of
this part:
    (1) The NOX authorized account representative of the
units may identify the percentage of NOX allowances to be
deducted from each such unit's compliance account to cover the unit's
share of NOX emissions from the common stack for a control
period. Such identification shall be made in the compliance
certification report submitted in accordance with Sec. 96.30.
    (2) Notwithstanding paragraph (b)(2)(i) of this section, the
Administrator will deduct NOX allowances for each such unit
until the number of NOX allowances deducted equals the
unit's identified percentage (under paragraph (e)(1) of this section)
of the number of tons of NOX emissions, as determined in
accordance with subpart H of this part, from the common stack for the
control period for which compliance is being determined or, if no
percentage is identified, an equal

[[Page 57529]]

percentage for each such unit, plus the number of allowances required
for deduction to account for actual utilization under Sec. 96.42(e) for
the control period.
    (f) The Administrator will record in the appropriate compliance
account or overdraft account all deductions from such an account
pursuant to paragraphs (b), (d), or (e) of this section.

Sec. 96.55  Banking.

    (a) NOX allowances may be banked for future use or
transfer in a compliance account, an overdraft account, or a general
account, as follows:
    (1) Any NOX allowance that is held in a compliance
account, an overdraft account, or a general account will remain in such
account unless and until the NOX allowance is deducted or
transferred under Sec. 96.31, Sec. 96.54, Sec. 96.56, subpart G of this
part, or subpart I of this part.
    (2) The Administrator will designate, as a ``banked''
NOX allowance, any NOX allowance that remains in
a compliance account, an overdraft account, or a general account after
the Administrator has made all deductions for a given control period
from the compliance account or overdraft account pursuant to Sec. 96.54.
    (b) Each year starting in 2004, after the Administrator has
completed the designation of banked NOX allowances under
paragraph (a)(2) of this section and before May 1 of the year, the
Administrator will determine the extent to which banked NOX
allowances may be used for compliance in the control period for the
current year, as follows:
    (1) The Administrator will determine the total number of banked
NOX allowances held in compliance accounts, overdraft
accounts, or general accounts.
    (2) If the total number of banked NOX allowances
determined, under paragraph (b)(1) of this section, to be held in
compliance accounts, overdraft accounts, or general accounts is less
than or equal to 10% of the sum of the State trading program budgets
for the control period for the States in which NOX Budget
units are located, any banked NOX allowance may be deducted
for compliance in accordance with Sec. 96.54.
    (3) If the total number of banked NOX allowances
determined, under paragraph (b)(1) of this section, to be held in
compliance accounts, overdraft accounts, or general accounts exceeds
10% of the sum of the State trading program budgets for the control
period for the States in which NOX Budget units are located,
any banked allowance may be deducted for compliance in accordance with
Sec. 96.54, except as follows:
    (i) The Administrator will determine the following ratio: 0.10
multiplied by the sum of the State trading program budgets for the
control period for the States in which NOX Budget units are
located and divided by the total number of banked NOX
allowances determined, under paragraph (b)(1) of this section, to be
held in compliance accounts, overdraft accounts, or general accounts.
    (ii) The Administrator will multiply the number of banked
NOX allowances in each compliance account or overdraft
account. The resulting product is the number of banked NOX
allowances in the account that may be deducted for compliance in
accordance with Sec. 96.54. Any banked NOX allowances in
excess of the resulting product may be deducted for compliance in
accordance with Sec. 96.54, except that, if such NOX
allowances are used to make a deduction, two such NOX
allowances must be deducted for each deduction of one NOX
allowance required under Sec. 96.54.
    (c) Any NOX Budget unit may reduce its NOX
emission rate in the 2001 or 2002 control period, the owner or operator
of the unit may request early reduction credits, and the permitting
authority may allocate NOX allowances in 2003 to the unit in
accordance with the following requirements.
    (1) Each NOX Budget unit for which the owner or operator
requests any early reduction credits under paragraph (c)(4) of this
section shall monitor NOX emissions in accordance with
subpart H of this part starting in the 2000 control period and for each
control period for which such early reduction credits are requested.
The unit's monitoring system availability shall be not less than 90
percent during the 2000 control period, and the unit must be in
compliance with any applicable State or Federal emissions or emissions-
related requirements.
    (2) NOX emission rate and heat input under paragraphs
(c)(3) through (5) of this section shall be determined in accordance
with subpart H of this part.
    (3) Each NOX Budget unit for which the owner or operator
requests any early reduction credits under paragraph (c)(4) of this
section shall reduce its NOX emission rate, for each control
period for which early reduction credits are requested, to less than
both 0.25 lb/mmBtu and 80 percent of the unit's NOX emission
rate in the 2000 control period.
    (4) The NOX authorized account representative of a
NOX Budget unit that meets the requirements of paragraphs
(c)(1)and (3) of this section may submit to the permitting authority a
request for early reduction credits for the unit based on
NOX emission rate reductions made by the unit in the control
period for 2001 or 2002 in accordance with paragraph (c)(3) of this
section.
    (i) In the early reduction credit request, the NOX
authorized account may request early reduction credits for such control
period in an amount equal to the unit's heat input for such control
period multiplied by the difference between 0.25 lb/mmBtu and the
unit's NOX emission rate for such control period, divided by
2000 lb/ton, and rounded to the nearest ton.
    (ii) The early reduction credit request must be submitted, in a
format specified by the permitting authority, by October 31 of the year
in which the NOX emission rate reductions on which the
request is based are made or such later date approved by the permitting
authority.
    (5) The permitting authority will allocate NOX
allowances, to NOX Budget units meeting the requirements of
paragraphs (c)(1) and (3) of this section and covered by early
reduction requests meeting the requirements of paragraph (c)(4)(ii) of
this section, in accordance with the following procedures:
    (i) Upon receipt of each early reduction credit request, the
permitting authority will accept the request only if the requirements
of paragraphs (c)(1), (c)(3), and (c)(4)(ii) of this section are met
and, if the request is accepted, will make any necessary adjustments to
the request to ensure that the amount of the early reduction credits
requested meets the requirement of paragraphs (c)(2) and (4) of this
section.
    (ii) If the State's compliance supplement pool has an amount of
NOX allowances not less than the number of early reduction
credits in all accepted early reduction credit requests for 2001 and
2002 (as adjusted under paragraph (c)(5)(i) of this section), the
permitting authority will allocate to each NOX Budget unit
covered by such accepted requests one allowance for each early
reduction credit requested (as adjusted under paragraph (c)(5)(i) of
this section).
    (iii) If the State's compliance supplement pool has a smaller
amount of NOX allowances than the number of early reduction
credits in all accepted early reduction credit requests for 2001 and
2002 (as adjusted under paragraph (c)(5)(i) of this section), the
permitting authority will allocate NOX allowances to each
NOX Budget unit covered by

[[Page 57530]]

such accepted requests according to the following formula:

Unit's allocated early reduction credits = [(Unit's adjusted early
reduction credits) / (Total adjusted early reduction credits
requested by all units)] x (Available NOX allowances from
the State's compliance supplement pool)

where:

    ``Unit's adjusted early reduction credits'' is the number of
early reduction credits for the unit for 2001 and 2002 in accepted
early reduction credit requests, as adjusted under paragraph
(c)(5)(i) of this section.
    ``Total adjusted early reduction credits requested by all
units'' is the number of early reduction credits for all units for
2001 and 2002 in accepted early reduction credit requests, as
adjusted under paragraph (c)(5)(i) of this section.
    ``Available NOX allowances from the State's
compliance supplement pool'' is the number of NOX
allowances in the State's compliance supplement pool and available
for early reduction credits for 2001 and 2002.

    (6) By May 1, 2003, the permitting authority will submit to the
Administrator the allocations of NOX allowances determined
under paragraph (c)(5) of this section. The Administrator will record
such allocations to the extent that they are consistent with the
requirements of paragraphs (c)(1) through (5) of this section.
    (7) NOX allowances recorded under paragraph (c)(6) of
this section may be deducted for compliance under Sec. 96.54 for the
control periods in 2003 or 2004. Notwithstanding paragraph (a) of this
section, the Administrator will deduct as retired any NOX
allowance that is recorded under paragraph (c)(6) of this section and
is not deducted for compliance in accordance with Sec. 96.54 for the
control period in 2003 or 2004.
    (8) NOX allowances recorded under paragraph (c)(6) of
this section are treated as banked allowances in 2004 for the purposes
of paragraphs (a) and (b) of this section.

Sec. 96.56  Account error.

    The Administrator may, at his or her sole discretion and on his or
her own motion, correct any error in any NOX Allowance
Tracking System account. Within 10 business days of making such
correction, the Administrator will notify the NOX authorized
account representative for the account.

Sec. 96.57  Closing of general accounts.

    (a) The NOX authorized account representative of a
general account may instruct the Administrator to close the account by

    (B) Incomplete application notice. A certification application will
be considered complete when all of the applicable information required
to be submitted under paragraph (b)(3)(ii) of this section has been
received by the permitting authority. If the certification application
is not complete, then the permitting authority will issue a written
notice of incompleteness that sets a reasonable date by which the
NOX authorized account representative must submit the
additional information required to complete the certification
application. If the NOX authorized account representative
does not comply with the notice of incompleteness by the specified
date, then the permitting authority may issue a notice of disapproval
under paragraph (b)(3)(iv)(C) of this section.
    (C) Disapproval notice. If the certification application shows that
any monitoring system or component thereof does not meet the
performance requirements of this part, or if the certification
application is incomplete and the requirement for disapproval under
paragraph (b)(3)(iv)(B) of this section has been met, the permitting
authority will issue a written notice of disapproval of the
certification application. Upon issuance of such notice of disapproval,
the provisional certification is invalidated by the permitting
authority and the data measured and recorded by each uncertified
monitoring system or component thereof shall not be considered valid
quality-assured data beginning with the date and hour of provisional
certification. The owner or operator shall follow the procedures for
loss of certification in paragraph (b)(3)(v) of this section for each
monitoring system or component thereof which is disapproved for initial
certification.
    (D) Audit decertification. The permitting authority may issue a
notice of disapproval of the certification status of a monitor in
accordance with Sec. 96.72(b).
    (v) Procedures for loss of certification. If the permitting
authority issues a notice of disapproval of a certification application
under paragraph

[[Page 57533]]

(b)(3)(iv)(C) of this section or a notice of disapproval of
certification status under paragraph (b)(3)(iv)(D) of this section, then:

Subpart I--Individual Unit Opt-ins

Sec. 96.80  Applicability.

    A unit that is in the State, is not a NOX Budget unit
under Sec. 96.4, vents all of its emissions to a stack, and is
operating, may qualify, under this subpart, to become a NOX
Budget opt-in source. A unit that is a NOX Budget unit, is
covered by a retired unit exemption under Sec. 96.5 that is in effect,
or is not operating is not eligible to become a NOX Budget
opt-in source.

Sec. 96.81  General.

    Except otherwise as provided in this part, a NOX Budget
opt-in source shall be treated as a NOX Budget unit for
purposes of applying subparts A through H of this part.

Sec. 96.82  NOX authorized account representative.

    A unit for which an application for a NOX Budget opt-in
permit is submitted and not denied or withdrawn, or a NOX
Budget opt-in source, located at the same source as one or more
NOX Budget units, shall have the same NOX
authorized account representative as such NOX Budget units.

Sec. 96.83  Applying for NOX Budget opt-in permit.

    (a) Applying for initial NOX Budget opt-in permit. In
order to apply for an initial NOX Budget opt-in permit, the
NOX authorized account representative of a unit qualified
under Sec. 96.80 may submit to the permitting authority at any time,
except as provided under Sec. 96.86(g):
    (1) A complete NOX Budget permit application under
Sec. 96.22;
    (2) A monitoring plan submitted in accordance with subpart H of
this part; and
    (3) A complete account certificate of representation under
Sec. 96.13, if no NOX authorized account representative has
been previously designated for the unit.
    (b) Duty to reapply. The NOX authorized account
representative of a NOX Budget opt-in source shall submit a
complete NOX Budget permit application under Sec. 96.22 to
renew the NOX Budget opt-in permit in accordance with
Sec. 96.21(c) and, if applicable, an updated monitoring plan in
accordance with subpart H of this part.

Sec. 96.84  Opt-in process.

    The permitting authority will issue or deny a NOX Budget
opt-in permit for a unit for which an initial application for a
NOX Budget opt-in permit under Sec. 96.83 is submitted, in
accordance with Sec. 96.20 and the following:
    (a) Interim review of monitoring plan. The permitting authority
will determine, on an interim basis, the sufficiency of the monitoring
plan accompanying the initial application for a NOX Budget
opt-in permit under Sec. 96.83. A monitoring plan is sufficient, for
purposes of interim review, if the plan appears to contain information
demonstrating that the NOX emissions rate and heat input of
the unit are monitored and reported in accordance with subpart H of
this part. A determination of sufficiency shall not be construed as
acceptance or approval of the unit's monitoring plan.
    (b) If the permitting authority determines that the unit's
monitoring plan is sufficient under paragraph (a) of this section and
after completion of monitoring system certification under subpart H of
this part, the NOX emissions rate and the heat input of the
unit shall be monitored and reported in accordance with subpart H of
this part for one full control period during which monitoring system
availability is not less than 90 percent and during which the unit is
in full compliance with any applicable State or Federal emissions or
emissions-related requirements. Solely for purposes of applying the
requirements in the prior sentence, the unit shall be treated as a
``NOX Budget unit'' prior to issuance of a NOX
Budget opt-in permit covering the unit.

[[Page 57536]]

    (c) Based on the information monitored and reported under paragraph
(b) of this section, the unit's baseline heat rate shall be calculated
as the unit's total heat input (in mmBtu) for the control period and
the unit's baseline NOX emissions rate shall be calculated
as the unit's total NOX emissions (in lb) for the control
period divided by the unit's baseline heat rate.
    (d) After calculating the baseline heat input and the baseline
NOX emissions rate for the unit under paragraph (c) of this
section, the permitting authority will serve a draft NOX
Budget opt-in permit on the NOX authorized account
representative of the unit.
    (e) Confirmation of intention to opt-in. Within 20 days after the
issuance of the draft NOX Budget opt-in permit, the
NOX authorized account representative of the unit must
submit to the permitting authority a confirmation of the intention to
opt in the unit or a withdrawal of the application for a NOX
Budget opt-in permit under Sec. 96.83. The permitting authority will
treat the failure to make a timely submission as a withdrawal of the
NOX Budget opt-in permit application.
    (f) Issuance of draft NOX Budget opt-in permit. If the
NOX authorized account representative confirms the intention
to opt-in the unit under paragraph (e) of this section, the permitting
authority will issue the draft NOX Budget opt-in permit in
accordance with Sec. 96.20.
    (g) Notwithstanding paragraphs (a) through (f) of this section, if
at any time before issuance of a draft NOX Budget opt-in
permit for the unit, the permitting authority determines that the unit
does not qualify as a NOX Budget opt-in source under
Sec. 96.80, the permitting authority will issue a draft denial of a
NOX Budget opt-in permit for the unit in accordance with
Sec. 96.20.
    (h) Withdrawal of application for NOX Budget opt-in
permit. A NOX authorized account representative of a unit
may withdraw its application for a NOX Budget opt-in permit
under Sec. 96.83 at any time prior to the issuance of the final
NOX Budget opt-in permit. Once the application for a
NOX Budget opt-in permit is withdrawn, a NOX
authorized account representative wanting to reapply must submit a new
application for a NOX Budget permit under Sec. 96.83.
    (i) Effective date. The effective date of the initial
NOX Budget opt-in permit shall be May 1 of the first control
period starting after the issuance of the initial NOX Budget
opt-in permit by the permitting authority. The unit shall be a
NOX Budget opt-in source and a NOX Budget unit as
of the effective date of the initial NOX Budget opt-in permit.

Sec. 96.85  NOX Budget opt-in permit contents.

    (a) Each NOX Budget opt-in permit (including any draft
or proposed NOX Budget opt-in permit, if applicable) will
contain all elements required for a complete NOX Budget opt-
in permit application under Sec. 96.22 as approved or adjusted by the
permitting authority.
    (b) Each NOX Budget opt-in permit is deemed to
incorporate automatically the definitions of terms under Sec. 96.2 and,
upon recordation by the Administrator under subpart F, G, or I of this
part, every allocation, transfer, or deduction of NOX
allowances to or from the compliance accounts of each NOX
Budget opt-in source covered by the NOX Budget opt-in permit
or the overdraft account of the NOX Budget source where the
NOX Budget opt-in source is located.

Sec. 96.86  Withdrawal from NOX Budget Trading Program.

    (a) Requesting withdrawal. To withdraw from the NOX
Budget Trading Program, the NOX authorized account
representative of a NOX Budget opt-in source shall submit to
the permitting authority a request to withdraw effective as of a
specified date prior to May 1 or after September 30. The submission
shall be made no later than 90 days prior to the requested effective
date of withdrawal.
    (b) Conditions for withdrawal. Before a NOX Budget opt-
in source covered by a request under paragraph (a) of this section may
withdraw from the NOX Budget Trading Program and the
NOX Budget opt-in permit may be terminated under paragraph
(e) of this section, the following conditions must be met:
    (1) For the control period immediately before the withdrawal is to
be effective, the NOX authorized account representative must
submit or must have submitted to the permitting authority an annual
compliance certification report in accordance with Sec. 96.30.
    (2) If the NOX Budget opt-in source has excess emissions
for the control period immediately before the withdrawal is to be
effective, the Administrator will deduct or has deducted from 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, the full amount
required under Sec. 96.54(d) for the control period.
    (3) After the requirements for withdrawal under paragraphs (b)(1)
and (2) of this section are met, the Administrator will deduct from 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, NOX
allowances equal in number to and allocated for the same or a prior
control period as any NOX allowances allocated to that
source under Sec. 96.88 for any control period for which the withdrawal
is to be effective. 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.
    (c) A NOX Budget opt-in source that withdraws from the
NOX Budget Trading Program shall comply with all
requirements under the NOX Budget Trading Program concerning
all years for which such NOX Budget opt-in source was a
NOX Budget opt-in source, even if such requirements arise or
must be complied with after the withdrawal takes effect.
    (d) Notification. (1) After the requirements for withdrawal under
paragraphs (a) and (b) of this section are met (including deduction of
the full amount of NOX allowances required), the permitting
authority will issue a notification to the NOX authorized
account representative of the NOX Budget opt-in source of
the acceptance of the withdrawal of the NOX Budget opt-in
source as of a specified effective date that is after such requirements
have been met and that is prior to May 1 or after September 30.
    (2) If the requirements for withdrawal under paragraphs (a) and (b)
of this section are not met, the permitting authority will issue a
notification to the NOX authorized account representative of
the NOX Budget opt-in source that the NOX Budget
opt-in source's request to withdraw is denied. If the NOX
Budget opt-in source's request to withdraw is denied, the
NOX Budget opt-in source shall remain subject to the
requirements for a NOX Budget opt-in source.
    (e) Permit amendment. After the permitting authority issues a
notification under paragraph (d)(1) of this section that the
requirements for withdrawal have been met, the permitting authority
will revise the NOX Budget permit covering the
NOX Budget opt-in source to terminate the NOX
Budget opt-in permit as of the effective date specified under paragraph
(d)(1) of this section. A NOX Budget opt-in source shall
continue to be a NOX Budget opt-in source until the
effective date of the termination.

[[Page 57537]]

    (f) Reapplication upon failure to meet conditions of withdrawal. If
the permitting authority denies the NOX Budget opt-in
source's request to withdraw, the NOX authorized account
representative may submit another request to withdraw in accordance
with paragraphs (a) and (b) of this section.
    (g) Ability to return to the NOX Budget Trading Program.
Once a NOX Budget opt-in source withdraws from the

opt-in permit is terminated under this section, the NOX
authority account representative may not submit another application for
a NOX Budget opt-in permit under Sec. 96.83 for the unit
prior to the date that is 4 years after the date on which the
terminated NOX Budget opt-in permit became effective.

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.

Sec. 96.88  NOX allowance allocations to opt-in units.

    (a) NOX allowance allocation. (1) By December 31
immediately before the first control period for which the
NOX Budget opt-in permit is effective, the permitting
