    The revisions and additions read as follows:

Sec.  75.34  Units with add-on emission controls.

    (a) The owner or operator of an affected unit equipped with add-on
SO2 and/or NOX emission controls shall provide
substitute data in accordance with paragraphs (a)(1), through (a)(5) of
this section for each hour in which quality-assured data from the
outlet SO2 and/or NOX monitoring system(s) are
not obtained.
* * * * *

availability for SO2 or NOX, calculated in
accordance with Sec.  75.32, is less than 90.0 percent and is greater
than or equal to 80.0 percent; and parametric data establishes that the
add-on emission controls were operating properly (i.e. within the range
of operating parameters provided in the quality assurance/

quality control program) during the hour, the owner or operator may:
    (i) Replace the maximum SO2 concentration recorded in
the 720 quality-assured monitor operating hours immediately preceding
the missing data period, with the maximum controlled SO2 concentration
recorded in the previous 720 quality-assured monitor operating hours;
or
    (ii) Replace the maximum NOX concentration(s) or
NOX emission rate(s) from the appropriate load bin(s) (based
on a lookback through the 2,160 quality-assured monitor operating hours
immediately preceding the missing data period), with the maximum
controlled NOX concentration(s) or emission rate(s) from the
appropriate load bin(s) in the same 2,160 quality-assured monitor
operating hour lookback period.

20. Section 75.38 is amended by revising paragraphs (a) and (c) to read
as follows.

Sec.  75.38  Standard missing data procedures for Hg CEMS.

    (a) Once 720 quality assured monitor operating hours of Hg
concentration data have been obtained following initial certification,
the owner or operator shall provide substitute data for Hg
concentration in accordance with the procedures in ( 75.33(b)(1)
through (b)(4), except that the term ``Hg concentration'' shall apply
rather than ``SO2 concentration,'' the term ``Hg
concentration monitoring system'' shall apply rather than
``SO2 pollutant concentration monitor,'' the term ``maximum
potential Hg concentration, as defined in section 2.1.7 of appendix A
to this part'' shall apply, rather than ``maximum potential
SO2 concentration'', and the percent monitor data
availability trigger conditions prescribed for Hg in Table 1 of Sec.
75.33 shall apply rather than the trigger conditions prescribed for
SO2.
* * * * *
    (c) For units with FGD systems or add-on Hg emission controls, when
the percent monitor data availability is less than 80.0 percent and is
greater than or equal to 70.0 percent, and a missing data period
occurs, consistent with Sec.  75.34(a)(3), for each missing data hour
in which the FGD or Hg emission controls are documented to be operating
properly, the owner or operator may report the maximum controlled Hg
concentration recorded in the previous 720 quality-assured monitor
operating hours. In addition, when the percent monitor data
availability is less than 70.0 percent and a missing data period
occurs, consistent with Sec.  75.34(a)(5), for each missing data hour
in which the FGD or Hg emission controls are documented to be operating
properly, the owner or operator may report the greater of the maximum
expected Hg concentration (MEC) or 1.25 times the maximum controlled Hg
concentration recorded in the previous 720 quality-assured monitor
operating hours. The MEC shall be determined in accordance with section

    The revisions and additions read as follows:

Sec.  75.39  Missing data procedures for sorbent trap monitoring
systems.

    (a) If a primary sorbent trap monitoring system has not been
certified by the applicable compliance date specified under a State or
Federal Hg mass emission reduction program that adopts the requirements
of subpart I of this part, and if quality-assured Hg concentration data
from a certified backup Hg monitoring system, reference method, or
approved alternative monitoring system are unavailable, the owner or
operator shall report the maximum potential Hg concentration, as
defined in section 2.1.7 of appendix A to this part, until the primary
system is certified.
    (b) For a certified sorbent trap system, a missing data period will
occur in the following circumstances, unless quality-assured Hg
concentration data from a certified backup Hg CEMS, sorbent trap
system, reference method, or approved alternative monitoring system are
available:
    (1) A gas sample is not extracted from the stack during unit
operation (e.g., during a monitoring system malfunction or when the
system undergoes maintenance); or
    (2) The results of the Hg analysis for the paired sorbent traps are
missing or invalid (as determined using the quality assurance
procedures in appendix K to this part). The missing data period begins
with the hour in which the paired sorbent traps for which the Hg
analysis is missing or invalid were put into service. The missing data
period ends at the first hour in which valid Hg concentration data are
obtained with another pair of sorbent traps (i.e., the hour at which
this pair of traps was placed in service), or with a certified backup
Hg CEMS, reference method, or approved alternative monitoring system.
    (c) Initial missing data procedures. Use the missing data
procedures in Sec.  75.31(b) until 720 hours of quality-assured Hg
concentration data have been collected with the sorbent trap monitoring
system(s), following initial certification.
    (d) Standard missing data procedures. Once 720 quality-assured
hours of data have been obtained with the sorbent trap system(s), begin
reporting the percent monitor data availability in accordance with
Sec.  75.32 and switch from the initial missing data procedures in
paragraph (c) of this section to the standard missing data procedures
in Sec.  75.38.
* * * * *

    (f) In cases where the owner or operator elects to use a primary Hg
CEMS and a certified redundant (or non-redundant) backup sorbent trap
monitoring system (or vice-versa), when both the primary and backup
monitoring systems are out-of-service and quality-assured Hg
concentration data from a temporary like-kind replacement analyzer,
reference method, or approved alternative monitoring system are
unavailable, the previous 720 quality-assured monitor operating hours
reported in the electronic quarterly report under Sec.  75.64 shall be
used for the required missing data lookback, irrespective of whether
these data were recorded by the Hg CEMS, the sorbent trap system, a
temporary like-kind replacement analyzer, a reference method, or an
approved alternative monitoring system.

certification in Sec.  75.4(a), (b), or (c). The initial quarterly
report shall contain hourly data beginning with the hour of provisional
certification or the hour corresponding to the relevant certification
deadline, whichever is earlier. For an affected unit subject to Sec.
75.4(d) that is shutdown on the relevant compliance date in Sec.
75.4(a) or has been placed in long-term cold storage (as defined in
Sec.  72.2 of this chapter), quarterly reports are not required. In
such cases, the owner or operator shall submit quarterly reports for
the unit beginning with the data from the quarter in which the unit
recommences commercial operation (where the initial quarterly report
contains hourly data beginning with the first hour of recommenced
commercial operation of the unit). For units placed into long-term cold
storage during a reporting quarter, the exemption from submitting
quarterly reports begins with the calendar quarter following the date
that the unit is placed into long-term cold storage. For any
provisionally-certified monitoring system, Sec.  75.20(a)(3) shall
apply for initial certifications, and Sec.  75.20(b)(5) shall apply for
recertifications. Each electronic report must be submitted to the
Administrator within 30 days following the end of each calendar
quarter. Prior to January 1, 2008, each electronic report shall include
for each affected unit (or group of units using a common stack), the
information provided in paragraphs (a)(1), (a)(2), and (a)(8) through
(a)(15) of this section. During the time period of January 1, 2008 to

0
32. Section 75.71 is amended by:
0
a. Revising the section heading;
0
b. In paragraph (a)(1), by removing the second occurrence of the phrase
``CO2 diluent gas monitor'' and adding in its place the
phrase ``CO2 diluent gas monitoring system'';
0
c. Removing the phrase ``O2 or CO2 diluent gas
monitor'' and adding in its place the phrase ``O2 or
CO2 monitoring system'', in paragraph (a)(2); and
0
d. Revising paragraph (e).
    The revision reads as follows:

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

* * * * *
    (e) Low mass emissions units. Notwithstanding the requirements of
paragraphs (c) and (d) of this section, for an affected unit using the
low mass emissions (LME) unit under Sec.  75.19 to estimate hourly
NOX emission rate, heat input and NOX mass
emissions, the owner or operator shall calculate the ozone season
NOX mass emissions by summing all of the estimated hourly
NOX mass emissions in the ozone season, as determined under
Sec.  75.19 (c)(4)(ii)(A), and dividing this sum by 2000 lb/ton.
* * * * *

0
33. Section 75.72 is amended by:
0
a. Revising the section heading and the introductory text;
0
b. Revising paragraph (c)(3); and
0
c. Removing and reserving paragraph (f).
    The revisions read as follows:

Sec.  75.72  Determination of NOX mass emissions for common stack and
multiple stack configurations.

    The owner or operator of an affected unit shall either: calculate
hourly NOX mass emissions (in lbs) by multiplying the hourly
NOX emission rate (in lbs/

mmBtu) by the hourly heat input rate (in mmBtu/hr) and the unit or
stack operating time (as defined in Sec.  72.2), or, as provided in
paragraph (e) of this section, calculate hourly NOX mass
emissions from the hourly NOX concentration (in ppm) and the
hourly stack flow rate (in scfh). Only one methodology for determining
NOX mass emissions shall be identified in the monitoring
plan for each monitoring location at any given time. 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.
* * * * *
    (c) * * *
    (3) Install, certify, operate, and maintain a NOX-
diluent CEMS and a flow monitoring system only on the main stack. If
this option is chosen, it is not necessary to designate the exhaust
configuration as a multiple stack configuration in the monitoring plan
required under Sec.  75.53, since only the main stack is monitored. For
each unit operating hour in which the bypass stack is used and the
emissions are either uncontrolled (or the add-on controls are not
documented to be operating properly), report NOX mass
emissions as follows. If the unit heat input is determined using a flow
monitor and a diluent monitor, report NOX mass emissions
using the maximum potential NOX emission rate, the maximum
potential flow rate, and either the maximum potential CO2
concentration or the minimum potential O2 concentration (as
applicable). The maximum potential NOX emission rate may be
specific to the type of fuel combusted in the unit during the bypass
(see Sec.  75.33(c)(8)). If the unit heat input is determined using a
fuel flowmeter, in accordance with appendix D to this part, report
NOX mass emissions as the product of the maximum potential
NOX emission rate and the actual measured hourly heat input
rate. Alternatively, for a unit with NOX add-on emission
controls, for each unit operating hour in which the bypass stack is
used but the add-on NOX emission controls are not bypassed,
the owner or operator may report the maximum controlled NOX
emission rate (MCR) instead of the maximum potential NOX
emission rate provided that the add-on controls are documented to be
operating properly, as described in the quality assurance/quality
control program for the unit, required by section 1 in appendix B of
this part. To provide the necessary documentation, the owner or
operator shall record parametric data to verify the proper operation of
the NOX add-on emission controls as described in Sec.
75.34(d). Furthermore, the owner or operator shall calculate the MCR
using the procedure described in section <IP_ADDRESS>(b) of appendix A to
this part by replacing the words ``maximum potential NOX
emission rate (MER)'' with the words ``maximum controlled
NOX emission rate (MCR)'' and by using the NOX
MEC in the calculations instead of the NOX MPC.

    (ii) * * *
    (F) Data Validation. For each RATA that is performed by April 30,
data validation shall be done according to sections 2.3.2(a)-(j) of
appendix B to this part. However, if a required RATA is not completed
by April 30, data from the monitoring system shall be invalid,
beginning with the first unit operating hour on or after May 1. The
owner or operator shall continue to invalidate all data from the CEMS
until either:
    (1) The required RATA of the CEMS has been performed and passed; or
    (2) A probationary calibration error test of the CEMS is passed in
accordance with Sec.  75.20(b)(3)(ii). Once the probationary
calibration error test has been passed, the owner or operator shall
perform the required RATA in accordance with the conditional data
validation provisions and within the 720 unit or stack operating hour
time frame specified in Sec.  75.20(b)(3) (subject to the restrictions
in paragraph (c)(3)(xii) of this section), and the term ``quality
assurance'' shall apply instead of the term ``recertification.''
However, in lieu of the provisions in Sec.  75.20(b)(3)(ix), the owner
or operator shall follow the applicable provisions in paragraphs
(c)(3)(xi) and (c)(3)(xii) of this section.
    (3) * * *
    (ii) For each gas monitor required by this subpart, linearity
checks shall be performed in the second and third calendar quarters, as
follows:
    (A) For the second calendar quarter, the pre-ozone season linearity
check required under paragraph (c)(2)(i) of this section shall be
performed by April 30.
    (B) For the third calendar quarter, a linearity check shall be
performed and passed no later than July 30.
    (C) Conduct each linearity check in accordance with the general
procedures in section 6.2 of appendix A to this part, except that the
data validation procedures in sections 6.2(a) through (f) of appendix A
do not apply.
    (D) Each linearity check shall be done ``hands-off,'' as described
in section 2.2.3(c) of appendix B to this part.
    (E) Data Validation. For second and third quarter linearity checks
performed by the applicable deadline (i.e., April 30 or July 30), data
validation shall be done in accordance with sections 2.2.3(a), (b),
(c), (e), and (h) of Appendix B to this part. However, if a required
linearity check for the second calendar quarter is not completed by
April 30, or if a required linearity check for the third calendar
quarter is not completed by July 30, data from the monitoring system
(or range) shall be invalid, beginning with the first unit operating
hour on or after May 1 or July 31, respectively. The owner or operator
shall continue to invalidate all data from the CEMS until either:
    (1) The required linearity check of the CEMS has been performed and
passed; or
    (2) A probationary calibration error test of the CEMS is passed in
accordance with Sec.  75.20(b)(3)(ii). Once the probationary
calibration error test has been passed, the owner or operator shall
perform the required linearity check in accordance with the conditional
data validation provisions and within the 168 unit or stack operating
hour time frame specified in Sec.  75.20(b)(3) (subject to the
restrictions in paragraph (c)(3)(xii) of this section), and the term
``quality assurance'' shall apply instead of the term
``recertification.'' However, in lieu of the provisions in Sec.
75.20(b)(3)(ix), the owner or operator shall follow the applicable
provisions in paragraphs (c)(3)(xi) and (c)(3)(xii) of this section.
    (F) A pre-season linearity check performed and passed in April
satisfies the linearity check requirement for the second quarter.
    (G) The third quarter linearity check requirement in paragraph
(c)(3)(ii)(B) of this section is waived if:
    (1) Due to infrequent unit operation, the 168 operating hour
conditional data validation period associated with a pre-season
linearity check extends into the third quarter; and
    (2) A linearity check is performed and passed within that
conditional data validation period.
* * * * *
    (6) * * *
    (iii) For the time periods described in paragraphs (c)(2)(i)(C) and
(c)(2)(ii)(E) of this section, hourly emission data and the results of
all daily calibration error tests and flow monitor interference checks
shall be recorded. The owner or operator may opt to report unit
operating data, daily calibration error test and flow monitor
interference check results, and hourly emission data in the time period
from April 1 through April

30. However, only the data recorded in the time period from May 1
through September 30 shall be used for NOX mass compliance
determination;

    (L) In Sec.  75.34(a)(3) and (a)(5), the phrases ``720 quality-
assured monitor operating hours within the ozone season'' and ``2160
quality-assured monitor operating hours within the ozone season'' apply
instead of ``720 quality-assured monitor operating hours'' and ``2160
quality-assured monitor operating hours'', respectively.
    (8) * * *
    (ii) For units with add-on emission controls, using the missing
data options in Sec. Sec.  75.34(a)(1) through 75.34(a)(5), the range
of operating parameters for add-on emission controls (as defined in the
quality assurance/quality control program for the unit required by
section 1 in appendix B to this part) and information for verifying
proper operation of the add-on emission controls during missing data
periods, as described in Sec.  75.34(d).
* * * * *
    (11) Units may qualify to use the optional NOX mass
emissions estimation protocol for gas-fired 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 chapter, except that the words
``year'', ``calendar year'' and ``calendar years'' in that definition
shall be replaced by the words ``ozone season'', ``ozone season'', and
``ozone seasons'', respectively. In addition, in the definition of the
term ``capacity factor'' in Sec.  72.2 of this chapter, the word
``annual'' shall be replaced by the words ``ozone season'' and the
number ``8,760'' shall be replaced by the number ``3,672''.

    The revisions and additions read as follows:

Sec.  75.81  Monitoring of Hg mass emissions and heat input at the unit
level.

* * * * *
    (a) * * *
    (4) If heat input is required to be reported under the applicable
State or Federal Hg mass emission reduction program that adopts the
requirements of this subpart, the owner or operator must meet the
general operating requirements for a flow monitoring system and an
O2 or CO2 monitoring system to measure heat input
rate.
* * * * *
    (c) * * *
    (1) The owner or operator must perform Hg emission testing one year
or less before the compliance date in Sec.  75.80(b), to determine the
Hg concentration (i.e., total vapor phase Hg) in the effluent.
    (i) The testing shall be performed using one of the Hg reference
methods listed in Sec.  75.22(a)(7), and shall consist of a minimum of
3 runs at the normal unit operating load, while combusting coal. The
coal combusted during the testing shall be representative of the coal
that will be combusted at the start of the Hg mass emissions reduction
program (preferably from the same source(s) of supply).
    (ii) The minimum time per run shall be 1 hour if Method 30A is
used. If either Method 29 in appendix A-8 to part 60 of this chapter,
ASTM D6784-02 (the Ontario Hydro method) (incorporated by reference
under Sec.  75.6 of this part), or Method 30B is used, paired samples
are required for each test run and the runs must be long enough to
ensure that sufficient Hg is collected to analyze. When Method 29 in
appendix A-8 to part 60 of this chapter or the Ontario Hydro method is
used, the test results shall be based on the vapor phase Hg collected
in the back-half of the sampling trains (i.e., the non-filterable
impinger catches). For each Method 29 in appendix A-8 to part 60 of
this chapter, Method 30B, or Ontario Hydro method test run, the paired
trains must meet the relative deviation (RD) requirement specified in
Sec.  75.22(a)(7) or Method 30B, as applicable. If the RD specification
is met, the results of the two samples shall be averaged
arithmetically.
    (iii) If the unit is equipped with flue gas desulfurization or add-
on Hg emission controls, the controls must be operating normally during
the testing, and, for the purpose of establishing proper operation of
the controls, the owner or operator shall record parametric data or
SO2 concentration data in accordance with Sec.
75.58(b)(3)(i).
    (iv) If two or more of units of the same type qualify as a group of
identical units in accordance with Sec.  75.19(c)(1)(iv)(B), the owner
or operator may test a subset of these units in lieu of testing each
unit individually. If this option is selected, the number of units
required to be tested shall be determined from Table LM-4 in Sec.
75.19. For the purposes of the required retests under paragraph (d)(4)
of this section, EPA strongly recommends that (to the extent
practicable) the same subset of the units not be tested in two
successive retests, and that every effort be made to ensure that each
unit in the group of identical units is tested in a timely manner.
    (2)(i) Based on the results of the emission testing, Equation 1 of
this section shall be used to provide a conservative estimate of the
annual Hg mass emissions from the unit:

[GRAPHIC] [TIFF OMITTED] TR24JA08.018

Where:

E = Estimated annual Hg mass emissions from the affected unit,
(ounces/year)
K = Units conversion constant, 9.978 x 10-10 oz-scm/
[mu]g-scf
N = Either 8,760 (the number of hours in a year) or the maximum
number of operating hours per year (if less than 8,760) allowed by
the unit's Federally-enforceable operating permit.
CHg = The highest Hg concentration ([mu]g/scm) from any
of the test runs or 0.50 [mu]g/scm, whichever is greater
Qmax = Maximum potential flow rate, determined according
to section <IP_ADDRESS> of appendix A to this part, (scfh)

    (ii) Equation 1 of this section assumes that the unit operates at
its maximum potential flow rate, either year-round or for the maximum
number of hours allowed by the operating permit (if unit operation is
restricted to less than 8,760 hours per year). If the permit restricts
the annual unit heat input but not the number of annual unit operating
hours, the owner or operator may divide the allowable annual heat input
(mmBtu) by the design rated heat input capacity of the unit (mmBtu/hr)
to determine the value of ``N'' in Equation 1. Also, note that if the
highest Hg concentration

measured in any test run is less than 0.50 [mu]g/scm, a default value
of 0.50 [mu]g/scm must be used in the calculations.
* * * * *
    (d) * * *
    (2) Following initial certification, the same default Hg
concentration value that was used to estimate the unit's annual Hg mass
emissions under paragraph (c) of this section shall be reported for
each unit operating hour, except as otherwise provided in paragraph
(d)(4)(iv) or (d)(6) of this section. The default Hg concentration
value shall be updated as appropriate, according to paragraph (d)(5) of
this section.
* * * * *
    (4) * * *
    (iv) An additional retest is required when there is a change in the
coal rank of the primary fuel (e.g., when the primary fuel is switched
from bituminous coal to lignite). Use ASTM D388-99 (incorporated by
reference under Sec.  75.6 of this part) to determine the coal rank.
The four principal coal ranks are anthracitic, bituminous,
subbituminous, and lignitic. The ranks of anthracite coal refuse (culm)
and bituminous coal refuse (gob) shall be anthracitic and bituminous,
respectively. The retest shall be performed within 720 unit operating
hours of the change.
    (5) The default Hg concentration used for reporting under Sec.
75.84 shall be updated after each required retest. This includes
retests that are required prior to the compliance date in Sec.
75.80(b). The updated value shall either be the highest Hg
concentration measured in any of the test runs or 0.50 [mu]g/scm,
whichever is greater. The updated value shall be applied beginning with
the first unit operating hour in which Hg emissions data are required
to be reported after completion of the retest, except as provided in
paragraph (d)(4)(iv) of this section, where the need to retest is
triggered by a change in the coal rank of the primary fuel. In that
case, apply the updated default Hg concentration beginning with the
first unit operating hour in which Hg emissions are required to be
reported after the date and hour of the fuel switch.
* * * * *
    (e) * * *
    (1) The methodology may not be used for reporting Hg mass emissions
at a common stack unless all of the units using the common stack are
affected units and the units' combined potential to emit does not
exceed 464 ounces of Hg per year times the number of units sharing the
stack, in accordance with paragraphs (c) and (d) of this section. If
the test results demonstrate that the units sharing the common stack
qualify as low mass emitters, the default Hg concentration used for
reporting Hg mass emissions at the common stack shall either be the
highest value obtained in any test run or 0.50 [mu]g/scm, whichever is
greater.
    (i) The initial emission testing required under paragraph (c) of
this section may be performed at the common stack if the following
conditions are met. Otherwise, testing of the individual units (or a
subset of the units, if identical, as described in paragraph (c)(1)(iv)
of this section) is required:
    (A) The testing must be done at a combined load corresponding to
the designated normal load level (low, mid, or high) for the units
sharing the common stack, in accordance with section <IP_ADDRESS> of
appendix A to this part;
    (B) All of the units that share the stack must be operating in a
normal, stable manner and at typical load levels during the emission
testing. The coal combusted in each unit during the testing must be
representative of the coal that will be combusted in that unit at the
start of the Hg mass emission reduction program (preferably from the
same source(s) of supply);
    (C) If flue gas desulfurization and/or add-on Hg emission controls
are used to reduce level the emissions exiting from the common stack,
these emission controls must be operating normally during the emission
testing and, for the purpose of establishing proper operation of the
controls, the owner or operator shall record parametric data or
SO2 concentration data in accordance with Sec.
75.58(b)(3)(i);
    (D) When calculating E, the estimated maximum potential annual Hg
mass emissions from the stack, substitute the maximum potential flow
rate through the common stack (as defined in the monitoring plan) and
the highest concentration from any test run (or 0.50 [mu]g/scm, if
greater) into Equation 1;
    (E) The calculated value of E shall be divided by the number of
units sharing the stack. If the result, when rounded to the nearest
ounce, does not exceed 464 ounces, the units qualify to use the low
mass emission methodology; and
    (F) If the units qualify to use the methodology, the default Hg
concentration used for reporting at the common stack shall be the
highest value obtained in any test run or 0.50 [mu]g/scm, whichever is
greater; or
    (ii) The retests required under paragraph (d)(4) of this section
may also be done at the common stack. If this testing option is chosen,
the testing shall be done at a combined load corresponding to the
designated normal load level (low, mid, or high) for the units sharing
the common stack, in accordance with section <IP_ADDRESS> of appendix A to
this part. Provided that the required load level is attained and that
all of the units sharing the stack are fed from the same on-site coal
supply during normal operation, it is not necessary for all of the
units sharing the stack to be in operation during a retest. However, if
two or more of the units that share the stack are fed from different
on-site coal supplies (e.g., one unit burns low-sulfur coal for
compliance and the other combusts higher-sulfur coal), then either:
    (A) Perform the retest with all units in normal operation; or
    (B) If this is not possible, due to circumstances beyond the
control of the owner or operator (e.g., a forced unit outage), perform
the retest with the available units operating and assess the test
results as follows. Use the Hg concentration obtained in the retest for
reporting purposes under this part if the concentration is greater than
or equal to the value obtained in the most recent test. If the retested
value is lower than the Hg concentration from the previous test,
continue using the higher value from the previous test for reporting
purposes and use that same higher Hg concentration value in Equation 1
to determine the due date for the next retest, as described in
paragraph (e)(1)(iii) of this section.
    (iii) If testing is done at the common stack, the due date for the
next scheduled retest shall be determined as follows:
    (A) Substitute the maximum potential flow rate for the common stack
(as defined in the monitoring plan) and the highest Hg concentration
from any test run (or 0.50 [mu]g/scm, if greater) into Equation 1;
    (B) If the value of E obtained from Equation 1, rounded to the
nearest ounce, is greater than 144 times the number of units sharing
the common stack, but less than or equal to 464 times the number of
units sharing the stack, the next retest is due in two QA operating
quarters;
    (C) If the value of E obtained from Equation 1, rounded to the
nearest ounce, is less than or equal to 144 times the number of units
sharing the common stack, the next retest is due in four QA operating
quarters.

    5.1.4 EPA Protocol Gases
    (a) An EPA Protocol Gas is a calibration gas mixture prepared
and analyzed according to Section 2 of the ``EPA Traceability
Protocol for Assay and Certification of Gaseous Calibration
Standards,'' September 1997, EPA-600/R-97/121 or such revised
procedure as approved by the Administrator (EPA Traceability
Protocol).
    (b) An EPA Protocol Gas must have a specialty gas producer-
certified uncertainty (95-percent confidence interval) that must not
be greater than 2.0 percent of the certified concentration (tag
value) of the gas mixture. The uncertainty must be calculated using
the statistical procedures (or equivalent statistical techniques)
that are listed in Section 2.1.8 of the EPA Traceability Protocol.
    (c) On and after January 1, 2009, a specialty gas producer
advertising calibration gas certification with the EPA Traceability
Protocol or distributing calibration gases as ``EPA Protocol Gas''
must participate in the EPA Protocol Gas Verification Program (PGVP)
described in Section 2.1.10 of the EPA Traceability Protocol or it
cannot use ``EPA'' in any form of advertising for these products,
unless approved by the Administrator. A specialty gas producer not
participating in the PGVP may not certify a calibration gas as an
EPA Protocol Gas, unless approved by the Administrator.
    (d) A copy of EPA-600/R-97/121 is available from the National
Technical Information Service, 5285 Port Royal Road, Springfield,
