emission limitations and you do not use a PM CPMS for monitoring PM
compliance, you must measure the (secondary) voltage and amperage of
the electrostatic precipitator collection plates during the particulate
matter performance test. Calculate the average electric power value
(secondary voltage x secondary current = secondary electric power) for
each test run. The operating limit for the electrostatic precipitator
is calculated as the lowest 1-hour average secondary electric power
measured during the most recent performance test demonstrating
compliance with the particulate matter emission limitations.
    (e) If you use activated carbon sorbent injection to comply with
the emission limitations, you must measure the sorbent flow rate during
the performance testing. The operating limit for the carbon sorbent
injection is calculated as the lowest 1-hour average sorbent flow rate
measured during the most recent performance test demonstrating
compliance with the mercury emission limitations. For energy recovery
units, when your unit operates at lower loads, multiply your sorbent
injection rate by the load fraction, as defined in this subpart, to
determine the required injection rate (e.g., for 50 percent load,
multiply the injection rate operating limit by 0.5).
    (f) If you use selective noncatalytic reduction to comply with the
emission limitations, you must measure the charge rate, the secondary
chamber temperature (if applicable to your CISWI unit), and the reagent
flow rate during the nitrogen oxides performance testing. The operating
limits for the selective noncatalytic reduction are calculated as the
highest 1-hour average charge rate, lowest secondary chamber
temperature,

and lowest reagent flow rate measured during the most recent
performance test demonstrating compliance with the nitrogen oxides
emission limitations.
    (g) If you use a dry scrubber to comply with the emission
limitations, you must measure the injection rate of each sorbent during
the performance testing. The operating limit for the injection rate of
each sorbent is calculated as the lowest 1-hour average injection rate
of each sorbent measured during the most recent performance test
demonstrating compliance with the hydrogen chloride emission
limitations. For energy recovery units, when your unit operates at
lower loads, multiply your sorbent injection rate by the load fraction,
as defined in this subpart, to determine the required injection rate
(e.g., for 50 percent load, multiply the injection rate operating limit
by 0.5).
    (h) If you do not use a wet scrubber, electrostatic precipitator,
or fabric filter to comply with the emission limitations, and if you do
not determine compliance with your particulate matter emission
limitation with either a particulate matter CEMS or a particulate
matter CPMS, you must maintain opacity to less than or equal to ten
percent opacity (1-hour block average).
    (i) If you use a PM CPMS to demonstrate compliance, you must
establish your PM CPMS operating limit and determine compliance with it
according to paragraphs (i)(1) through (5) of this section:
    (1) During the initial performance test or any such subsequent
performance test that demonstrates compliance with the PM limit, record
all hourly average output values (milliamps, or the digital signal
equivalent) from the PM CPMS for the periods corresponding to the test
runs (e.g., three 1-hour average PM CPMS output values for three 1-hour
test runs):
    (i) Your PM CPMS must provide a 4-20 milliamp output, or the
digital signal equivalent, and the establishment of its relationship to
manual reference method measurements must be determined in units of
milliamps or digital bits;
    (ii) Your PM CPMS operating range must be capable of reading PM
concentrations from zero to a level equivalent to at least two times
your allowable emission limit. If your PM CPMS is an auto-ranging
instrument capable of multiple scales, the primary range of the
instrument must be capable of reading PM concentration from zero to a
level equivalent to two times your allowable emission limit; and
    (iii) During the initial performance test or any such subsequent
performance test that demonstrates compliance with the PM limit, record
and average all milliamp output values, or their digital equivalent,
from the PM CPMS for the periods corresponding to the compliance test
runs (e.g., average all your PM CPMS output values for three
corresponding 2-hour Method 5I test runs).
    (2) If the average of your three PM performance test runs are below
75 percent of your PM emission limit, you must calculate an operating
limit by establishing a relationship of PM CPMS signal to PM
concentration using the PM CPMS instrument zero, the average PM CPMS
output values corresponding to the three compliance test runs, and the
average PM concentration from the Method 5 or performance test with the
procedures in (i)(1)through (5) of this section:
    (i) Determine your instrument zero output with one of the following
procedures:
    (A) Zero point data for in-situ instruments should be obtained by
removing the instrument from the stack and monitoring ambient air on a
test bench;
    (B) Zero point data for extractive instruments should be obtained
by removing the extractive probe from the stack and drawing in clean
ambient air;
    (C) The zero point can also can be established obtained by
performing manual reference method measurements when the flue gas is
free of PM emissions or contains very low PM concentrations (e.g., when
your process is not operating, but the fans are operating or your
source is combusting only natural gas) and plotting these with the
compliance data to find the zero intercept; and
    (D) If none of the steps in paragraphs (i)(2)(i)(A) through (C) of
this section are possible, you must use a zero output value provided by
the manufacturer.
    (ii) Determine your PM CPMS instrument average in milliamps, or the
digital equivalent, and the average of your corresponding three PM
compliance test runs, using equation 1:
[GRAPHIC] [TIFF OMITTED] TR23JN16.008

Where:

X1 = the PM CPMS output data points for the three runs
constituting the performance test,
Y1 = the PM concentration value for the three runs
constituting the performance test, and
n = the number of data points.

    (iii) With your instrument zero expressed in milliamps, or the
digital equivalent, your three run average PM CPMS milliamp value, or
its digital equivalent, and your three run average PM concentration
from your three compliance tests, determine a relationship of mg/dscm
per milliamp or digital signal equivalent, with equation 2:
[GRAPHIC] [TIFF OMITTED] TR23JN16.009

Where:

R = the relative mg/dscm per milliamp, or the digital equivalent,
for your PM CPMS,
Y1 = the three run average mg/dscm PM concentration,
X1 = the three run average milliamp output, or the
digital equivalent, from you PM CPMS, and
z = the milliamp or digital signal equivalent of your instrument
zero determined from paragraph (i)(2)(i) of this section.

    (iv) Determine your source specific 30-day rolling average
operating limit using the mg/dscm per milliamp value, or per digital
signal equivalent, from equation 2 in equation 3, below. This sets your
operating limit at the PM CPMS output value corresponding to 75 percent
of your emission limit:

[GRAPHIC] [TIFF OMITTED] TR23JN16.010

Where:

Ol = the operating limit for your PM CPMS on a 30-day
rolling average, in milliamps or their digital signal equivalent,
L = your source emission limit expressed in mg/dscm,
z = your instrument zero in milliamps or digital equivalent,
determined from paragraph (i)(2)(i) of this section, and
R = the relative mg/dscm per milliamp, or per digital signal output
equivalent, for your PM CPMS, from equation 2.

    (3) If the average of your three PM compliance test runs is at or
above 75 percent of your PM emission limit you must determine your
operating limit by averaging the PM CPMS milliamp or digital signal
output corresponding to your three PM performance test runs that
demonstrate compliance with the emission limit using equation 4 and you
must submit all compliance test and PM CPMS data according to the
reporting requirements in paragraph (i)(5) of this section:
[GRAPHIC] [TIFF OMITTED] TR23JN16.011

Where:

X1 = the PM CPMS data points for all runs i,
n = the number of data points, and
Oh = your site specific operating limit, in milliamps or
digital signal equivalent.

    (4) To determine continuous compliance, you must record the PM CPMS
output data for all periods when the process is operating and the PM
CPMS is not out-of-control. You must demonstrate continuous compliance
by using all quality-assured hourly average data collected by the PM
CPMS for all operating hours to calculate the arithmetic average
operating parameter in units of the operating limit (e.g., milliamps or
digital signal bits, PM concentration, raw data signal) on a 30-day
rolling average basis.
    (5) For PM performance test reports used to set a PM CPMS operating
limit, the electronic submission of the test report must also include
the make and model of the PM CPMS instrument, serial number of the
instrument, analytical principle of the instrument (e.g., beta
attenuation), span of the instruments primary analytical range,
milliamp or digital signal value equivalent to the instrument zero
output, technique by which this zero value was determined, and the
average milliamp or digital signals corresponding to each PM compliance
test run.

Sec.  60.2680  What if I do not use a wet scrubber, fabric filter,
activated carbon injection, selective noncatalytic reduction, an
electrostatic precipitator, or a dry scrubber to comply with the
emission limitations?

    (a) If you use an air pollution control device other than a wet
scrubber, activated carbon injection, selective noncatalytic reduction,
fabric filter, an electrostatic precipitator, or a dry scrubber or
limit emissions in some other manner, including mass balances, to
comply with the emission limitations under Sec.  60.2670, you must
petition the EPA Administrator for specific operating limits to be
established during the initial performance test and continuously
monitored thereafter. You must submit the petition at least sixty days
before the performance test is scheduled to begin. Your petition must
include the five items listed in paragraphs (a)(1) through (5) of this
section:
    (1) Identification of the specific parameters you propose to use as
additional operating limits;
    (2) A discussion of the relationship between these parameters and
emissions of regulated pollutants, identifying how emissions of
regulated pollutants change with changes in these parameters and how
limits on these parameters will serve to limit emissions of regulated
pollutants;
    (3) A discussion of how you will establish the upper and/or lower
values for these parameters which will establish the operating limits
on these parameters;
    (4) A discussion identifying the methods you will use to measure
and the instruments you will use to monitor these parameters, as well
as the relative accuracy and precision of these methods and
instruments; and
    (5) A discussion identifying the frequency and methods for
recalibrating the instruments you will use for monitoring these
parameters.
    (b) [Reserved]

Model Rule--Performance Testing

Sec.  60.2690  How do I conduct the initial and annual performance
test?

    (a) All performance tests must consist of a minimum of three test
runs conducted under conditions representative of normal operations.
    (b) You must document that the waste burned during the performance
test is representative of the waste burned under normal operating
conditions by maintaining a log of the quantity of waste burned (as
required in Sec.  60.2740(b)(1)) and the types of waste burned during
the performance test.
    (c) All performance tests must be conducted using the minimum run
duration specified in tables 2 and 6 through 9 of this subpart.
    (d) Method 1 of appendix A of this part must be used to select the
sampling location and number of traverse points.
    (e) Method 3A or 3B of appendix A of this part must be used for gas
composition analysis, including measurement of oxygen concentration.
Method 3A or 3B of appendix A of this part must be used simultaneously
with each method.
    (f) All pollutant concentrations, except for opacity, must be
adjusted to 7 percent oxygen using equation 5 of this section:
[GRAPHIC] [TIFF OMITTED] TR23JN16.012

Where:

Cadj = pollutant concentration adjusted to 7 percent
oxygen;
Cmeas = pollutant concentration measured on a dry basis;
(20.9-7) = 20.9 percent oxygen-7 percent oxygen (defined oxygen
correction basis);
20.9 = oxygen concentration in air, percent; and
%O2 = oxygen concentration measured on a dry basis,
percent.

    (g) You must determine dioxins/furans toxic equivalency by
following the procedures in paragraphs (g)(1) through (4) of this
section:
    (1) Measure the concentration of each dioxin/furan tetra- through
octa-isomer emitted using EPA Method 23 at 40 CFR part 60, appendix A;
    (2) Quantify isomers meeting identification criteria 2, 3, 4, and 5
in Section <IP_ADDRESS> of Method 23, regardless of whether the isomers meet
identification criteria 1 and 7. You must quantify the isomers per
Section 9.0 of Method 23. [Note: You may reanalyze the sample aliquot
or split to reduce the number of isomers not meeting identification
criteria 1 or 7 of Section <IP_ADDRESS>.];
    (3) For each dioxin/furan (tetra- through octa-chlorinated) isomer
measured in accordance with paragraph (g)(1) and (2) of this section,
multiply the isomer concentration by its corresponding toxic
equivalency factor specified in table 4 of this subpart; and
    (4) Sum the products calculated in accordance with paragraph (g)(3)
of this section to obtain the total concentration of dioxins/furans
emitted in terms of toxic equivalency.
    (h) Method 22 at 40 CFR part 60, appendix A-7 must be used to
determine compliance with the fugitive ash emission limit in table 2 of
this subpart or tables 6 through 9 of this subpart.
    (i) If you have an applicable opacity operating limit, you must
determine compliance with the opacity limit using Method 9 at 40 CFR
part 60, appendix A-4, based on three 1-hour blocks consisting of ten
6-minute average opacity values, unless you are required to install a
continuous opacity monitoring system, consistent with Sec.  60.2710 and
Sec.  60.2730.
    (j) You must determine dioxins/furans total mass basis by following
the procedures in paragraphs (j)(1) through (3) of this section:
    (1) Measure the concentration of each dioxin/furan tetra- through
octa-chlorinated isomer emitted using EPA Method 23 at 40 CFR part 60,
appendix A-7;
    (2) Quantify isomers meeting identification criteria 2, 3, 4, and 5
in Section <IP_ADDRESS> of Method 23, regardless of whether the isomers meet
identification criteria 1 and 7. You must quantify the isomers per
Section 9.0 of Method 23. (Note: You may reanalyze the sample aliquot
or split to reduce the number of isomers not meeting identification
criteria 1 or 7 of Section <IP_ADDRESS>.); and
    (3) Sum the quantities measured in accordance with paragraphs
(j)(1) and (2) of this section to obtain the total concentration of
dioxins/furans emitted in terms of total mass basis.

Sec.  60.2695  How are the performance test data used?

    You use results of performance tests to demonstrate compliance with
the emission limitations in table 2 of this subpart or tables 6 through
9 of this subpart.

Model Rule--Initial Compliance Requirements

Sec.  60.2700  How do I demonstrate initial compliance with the amended
emission limitations and establish the operating limits?

    You must conduct a performance test, as required under Sec. Sec.
60.2670 and 60.2690, to determine compliance with the emission
limitations in table 2 of this subpart and tables 6 through 9 of this
subpart, to establish compliance with any opacity operating limits in
Sec.  60.2675, to establish the kiln-specific emission limit in Sec.
60.2710(y), as applicable, and to establish operating limits using the
procedures in Sec.  60.2675 or Sec.  60.2680. The performance test must
be conducted using the test methods listed in table 2 of this subpart
and tables 6 through 9 of this subpart and the procedures in Sec.
60.2690. The use of the bypass stack during a performance test shall
invalidate the performance test. You must conduct a performance
evaluation of each continuous monitoring system within 60 days of
installation of the monitoring system.

Sec.  60.2705  By what date must I conduct the initial performance
test?

    (a) The initial performance test must be conducted no later than
180 days after your final compliance date. Your final compliance date
is specified in table 1 of this subpart.
    (b) If you commence or recommence combusting a solid waste at an
existing combustion unit at any commercial or industrial facility and
you conducted a test consistent with the provisions of this subpart
while combusting the given solid waste within the 6 months preceding
the reintroduction of that solid waste in the combustion chamber, you
do not need to retest until 6 months from the date you reintroduce that
solid waste.
    (c) If you commence or recommence combusting a solid waste at an
existing combustion unit at any commercial or industrial facility and
you have not conducted a performance test consistent with the
provisions of this subpart while combusting the given solid waste
within the 6 months preceding the reintroduction of that solid waste in
the combustion chamber, you must conduct a performance test within 60
days from the date you reintroduce solid waste.

Sec.  60.2706  By what date must I conduct the initial air pollution
control device inspection?

    (a) The initial air pollution control device inspection must be
conducted within 60 days after installation of the control device and
the associated CISWI unit reaches the charge rate at which it will
operate, but no later than 180 days after the final compliance date for
meeting the amended emission limitations.
    (b) Within 10 operating days following an air pollution control
device inspection, all necessary repairs must be completed unless the
owner or operator obtains written approval from the state agency
establishing a date whereby all necessary repairs of the designated
facility must be completed.

Model Rule--Continuous Compliance Requirements

Sec.  60.2710  How do I demonstrate continuous compliance with the
amended emission limitations and the operating limits?

    (a) Compliance with standards. (1) The emission standards and
operating requirements set forth in this subpart apply at all times.
    (2) If you cease combusting solid waste you may opt to remain
subject to the provisions of this subpart. Consistent with the
definition of CISWI unit, you are subject to the requirements of this
subpart at least 6 months following the last date of solid waste
combustion. Solid waste combustion is ceased when solid waste is not in
the combustion chamber (i.e., the solid waste feed to the combustor has
been cut off for a period of time not less than the solid waste
residence time).
    (3) If you cease combusting solid waste you must be in compliance
with any newly applicable standards on the effective date of the waste-
to-fuel switch. The effective date of the waste-to-fuel switch is a
date selected by you, that must be at least 6 months from the date that
you ceased combusting solid waste, consistent with Sec.  60.2710(a)(2).
Your source must remain in compliance

with this subpart until the effective date of the waste-to-fuel switch.
    (4) If you own or operate an existing commercial or industrial
combustion unit that combusted a fuel or non-waste material, and you
commence or recommence combustion of solid waste, you are subject to
the provisions of this subpart as of the first day you introduce or
reintroduce solid waste to the combustion chamber, and this date
constitutes the effective date of the fuel-to-waste switch. You must
complete all initial compliance demonstrations for any Section 112
standards that are applicable to your facility before you commence or
recommence combustion of solid waste. You must provide 30 days prior
notice of the effective date of the waste-to-fuel switch. The
notification must identify:
    (i) The name of the owner or operator of the CISWI unit, the
location of the source, the emissions unit(s) that will cease burning
solid waste, and the date of the notice;
    (ii) The currently applicable subcategory under this subpart, and
any 40 CFR part 63 subpart and subcategory that will be applicable
after you cease combusting solid waste;
    (iii) The fuel(s), non-waste material(s) and solid waste(s) the
CISWI unit is currently combusting and has combusted over the past 6
months, and the fuel(s) or non-waste materials the unit will commence
combusting;
    (iv) The date on which you became subject to the currently
applicable emission limits;
    (v) The date upon which you will cease combusting solid waste, and
the date (if different) that you intend for any new requirements to
become applicable (i.e., the effective date of the waste-to-fuel
switch), consistent with paragraphs (a)(2) and (3) of this section.
    (5) All air pollution control equipment necessary for compliance
with any newly applicable emissions limits which apply as a result of
the cessation or commencement or recommencement of combusting solid
waste must be installed and operational as of the effective date of the
waste-to-fuel, or fuel-to-waste switch.
    (6) All monitoring systems necessary for compliance with any newly
applicable monitoring requirements which apply as a result of the
cessation or commencement or recommencement of combusting solid waste
must be installed and operational as of the effective date of the
waste-to-fuel, or fuel-to-waste switch. All calibration and drift
checks must be performed as of the effective date of the waste-to-fuel,
or fuel-to-waste switch. Relative accuracy tests must be performed as
of the performance test deadline for PM CEMS (if PM CEMS are elected to
demonstrate continuous compliance with the particulate matter emission
limits). Relative accuracy testing for other CEMS need not be repeated
if that testing was previously performed consistent with section 112
monitoring requirements or monitoring requirements under this subpart.
    (b) You must conduct an annual performance test for the pollutants
listed in table 2 of this subpart or tables 6 through 9 of this subpart
and opacity for each CISWI unit as required under Sec.  60.2690. The
annual performance test must be conducted using the test methods listed
in table 2 of this subpart or tables 6 through 9 of this subpart and
the procedures in Sec.  60.2690. Opacity must be measured using EPA
Reference Method 9 at 40 CFR part 60. Annual performance tests are not
required if you use CEMS or continuous opacity monitoring systems to
determine compliance.
    (c) You must continuously monitor the operating parameters
specified in Sec.  60.2675 or established under Sec.  60.2680 and as
specified in Sec.  60.2735. Operation above the established maximum or
below the established minimum operating limits constitutes a deviation
from the established operating limits. Three-hour block average values
are used to determine compliance (except for baghouse leak detection
system alarms) unless a different averaging period is established under
Sec.  60.2680 or, for energy recovery units, where the averaging time
for each operating parameter is a 30-day rolling, calculated each hour
as the average of the previous 720 operating hours over the previous 30
days of operation. Operation above the established maximum, below the
established minimum, or outside the allowable range of the operating
limits specified in paragraph (a) of this section constitutes a
deviation from your operating limits established under this subpart,
except during performance tests conducted to determine compliance with
the emission and operating limits or to establish new operating limits.
Operating limits are confirmed or reestablished during performance
tests.
    (d) You must burn only the same types of waste and fuels used to
establish subcategory applicability (for ERUs) and operating limits
during the performance test.
    (e) For energy recovery units, incinerators, and small remote
units, you must perform annual visual emissions test for ash handling.
    (f) For energy recovery units, you must conduct an annual
performance test for opacity using EPA Reference Method 9 at 40 CFR
part 60 (except where particulate matter continuous monitoring system
or continuous parameter monitoring systems are used) and the pollutants
listed in table 7 of this subpart.
    (g) For facilities using a CEMS to demonstrate compliance with the
carbon monoxide emission limit, compliance with the carbon monoxide
emission limit may be demonstrated by using the CEMS according to the
following requirements:
    (1) You must measure emissions according to Sec.  60.13 to
calculate 1-hour arithmetic averages, corrected to 7 percent oxygen.
CEMS data during startup and shutdown, as defined in this subpart, are
not corrected to 7 percent oxygen, and are measured at stack oxygen
content. You must demonstrate initial compliance with the carbon
monoxide emissions limit using a 30-day rolling average of the 1-hour
arithmetic average emission concentrations, including CEMS data during
startup and shutdown as defined in this subpart, calculated using
equation 19-19 in section 12.4.1 of EPA Reference Method 19 at 40 CFR
part 60, appendix A-7.
    (2) Operate the carbon monoxide continuous emissions monitoring
system in accordance with the applicable requirements of performance
specification 4A of appendix B and the quality assurance procedures of
appendix F of this part.
    (h) Coal and liquid/gas energy recovery units with annual average
heat input rates greater than 250 MMBtu/hr may elect to demonstrate
continuous compliance with the particulate matter emissions limit using
a particulate matter CEMS according to the procedures in Sec.
60.2730(n) instead of the continuous parameter monitoring system
specified in Sec.  60.2710(i). Coal and liquid/gas energy recovery
units with annual average heat input rates less than 250 MMBtu/hr,
incinerators, and small remote incinerators may also elect to
demonstrate compliance using a particulate matter CEMS according to the
procedures in Sec.  60.2730(n) instead of particulate matter testing
with EPA Method 5 at 40 CFR part 60, appendix A-3 and, if applicable,
the continuous opacity monitoring requirements in paragraph (i) of this
section.
    (i) For energy recovery units with annual average heat input rates
greater than or equal to 10 MMBTU/hour but less than 250 MMBtu/hr you
must install, operate, certify and maintain a continuous opacity
monitoring system (COMS) according to the procedures in Sec.  60.2730.

    (j) For waste-burning kilns, you must conduct an annual performance
test for the pollutants (except mercury and particulate matter, and
hydrogen chloride if no acid gas wet scrubber is used) listed in table
8 of this subpart. If you do not use an acid gas wet scrubber or dry
scrubber, you must determine compliance with the hydrogen chloride
emissions limit according to the requirements in paragraph (j)(1) of
this section. You must determine compliance with the mercury emissions
limit using a mercury CEMS according to paragraph (j)(2) of this
section. You must determine compliance with particulate matter using
CPMS:
    (1) If you monitor compliance with the HCl emissions limit by
operating an HCl CEMS, you must do so in accordance with Performance
Specification 15 (PS 15) of appendix B to 40 CFR part 60, or, PS 18 of
appendix B to 40 CFR part 60. You must operate, maintain, and quality
assure a HCl CEMS installed and certified under PS 15 according to the
quality assurance requirements in Procedure 1 of appendix F to 40 CFR
part 60 except that the Relative Accuracy Test Audit requirements of
Procedure 1 must be replaced with the validation requirements and
criteria of sections 11.1.1 and 12.0 of PS 15. You must operate,
maintain and quality assure a HCl CEMS installed and certified under PS
18 according to the quality assurance requirements in Procedure 6 of
appendix F to 40 CFR part 60. For any performance specification that
you use, you must use Method 321 of appendix A to 40 CFR part 63 as the
reference test method for conducting relative accuracy testing. The
span value and calibration requirements in paragraphs (j)(1)(i) and
(ii) of this section apply to all HCl CEMS used under this subpart:
    (i) You must use a measurement span value for any HCl CEMS of 0-10
ppmvw unless the monitor is installed on a kiln without an inline raw
mill. Kilns without an inline raw mill may use a higher span value
sufficient to quantify all expected emissions concentrations. The HCl
CEMS data recorder output range must include the full range of expected
HCl concentration values which would include those expected during
``mill off'' conditions. The corresponding data recorder range shall be
documented in the site-specific monitoring plan and associated records;
and
    (ii) In order to quality assure data measured above the span value,
you must use one of the three options in paragraphs (j)(1)(ii)(A)
through (C) of this section:
    (A) Include a second span that encompasses the HCl emission
concentrations expected to be encountered during ``mill off''
conditions. This second span may be rounded to a multiple of 5 ppm of
total HCl. The requirements of the appropriate HCl monitor performance
specification shall be followed for this second span with the exception
that a RATA with the mill off is not required;
    (B) Quality assure any data above the span value by proving
instrument linearity beyond the span value established in paragraph
(j)(1)(i) of this section using the following procedure. Conduct a
weekly ``above span linearity'' calibration challenge of the monitoring
system using a reference gas with a certified value greater than your
highest expected hourly concentration or greater than 75% of the
highest measured hourly concentration. The ``above span'' reference gas
must meet the requirements of the applicable performance specification
and must be introduced to the measurement system at the probe. Record
and report the results of this procedure as you would for a daily
calibration. The ``above span linearity'' challenge is successful if
the value measured by the HCl CEMS falls within 10 percent of the
certified value of the reference gas. If the value measured by the HCl
CEMS during the above span linearity challenge exceeds 10 percent of
the certified value of the reference gas, the monitoring system must be
evaluated and repaired and a new ``above span linearity'' challenge met
before returning the HCl CEMS to service, or data above span from the
HCl CEMS must be subject to the quality assurance procedures
established in (j)(1)(ii)(D) of this section. In this manner values
measured by the HCl CEMS during the above span linearity challenge
exceeding +/-20 percent of the certified value of the reference gas
must be normalized using equation 6;
    (C) Quality assure any data above the span value established in
paragraph (j)(1)(i) of this section using the following procedure. Any
time two consecutive one-hour average measured concentration of HCl
exceeds the span value you must, within 24 hours before or after,
introduce a higher, ``above span'' HCl reference gas standard to the
HCl CEMS. The ``above span'' reference gas must meet the requirements
of the applicable performance specification and target a concentration
level between 50 and 150 percent of the highest expected hourly
concentration measured during the period of measurements above span,
and must be introduced at the probe. While this target represents a
desired concentration range that is not always achievable in practice,
it is expected that the intent to meet this range is demonstrated by
the value of the reference gas. Expected values may include above span
calibrations done before or after the above-span measurement period.
Record and report the results of this procedure as you would for a
daily calibration. The ``above span'' calibration is successful if the
value measured by the HCl CEMS is within 20 percent of the certified
value of the reference gas. If the value measured by the HCl CEMS is
not within 20 percent of the certified value of the reference gas, then
you must normalize the stack gas values measured above span as
described in paragraph (j)(1)(ii)(D) of this section. If the ``above
span'' calibration is conducted during the period when measured
emissions are above span and there is a failure to collect the one data
point in an hour due to the calibration duration, then you must
determine the emissions average for that missed hour as the average of
hourly averages for the hour preceding the missed hour and the hour
following the missed hour. In an hour where an ``above span''
calibration is being conducted and one or more data points are
collected, the emissions average is represented by the average of all
valid data points collected in that hour; and
    (D) In the event that the ``above span'' calibration is not
successful (i.e., the HCl CEMS measured value is not within 20 percent
of the certified value of the reference gas), then you must normalize
the one-hour average stack gas values measured above the span during
the 24-hour period preceding or following the ``above span''
calibration for reporting based on the HCl CEMS response to the
reference gas as shown in equation 6:
[GRAPHIC] [TIFF OMITTED] TR23JN16.013

    Only one ``above span'' calibration is needed per 24-hour period.
    (2) Compliance with the mercury emissions limit must be determined
using a mercury CEMS according to the following requirements:

    (i) You must operate a CEMS in accordance with performance
specification 12A at 40 CFR part 60, appendix B or a sorbent trap based
integrated monitor in accordance with performance specification 12B at
40 CFR part 60, appendix B. The duration of the performance test must
be a calendar month. For each calendar month in which the waste-burning
kiln operates, hourly mercury concentration data and stack gas
volumetric flow rate data must be obtained. You must demonstrate
compliance with the mercury emissions limit using a 30-day rolling
average of these 1-hour mercury concentrations, including CEMS data
during startup and shutdown as defined in this subpart, calculated
using equation 19-19 in section 12.4.1 of EPA Reference Method 19 at 40

    (s) For facilities using a CEMS to demonstrate compliance with the
sulfur dioxide emission limit, compliance with the sulfur dioxide
emission limit may be demonstrated by using the CEMS specified in Sec.
60.2730 to measure sulfur dioxide. CEMS data during startup and
shutdown, as defined in this subpart, are not corrected to 7 percent
oxygen, and are measured at stack oxygen content. You must calculate a
30-day rolling average of the 1-hour arithmetic average emission
concentrations, including CEMS data during startup and shutdown as
defined in this subpart, using equation 19-19 in section 12.4.1 of EPA
Reference Method 19 at 40 CFR part 60, appendix A-7. The sulfur dioxide
CEMS must be operated according to performance specification 2 in
appendix B of this part and must follow the procedures and methods
specified in paragraph (s) of this section. For sources that have
actual inlet emissions less than 100 parts per million dry volume, the
relative accuracy criterion for inlet sulfur dioxide CEMS should be no
greater than 20 percent of the mean value of the reference method test
data in terms of the units of the emission standard, or 5 parts per
million dry volume absolute value of the mean difference between the
reference method and the CEMS, whichever is greater:
    (1) During each relative accuracy test run of the CEMS required by
performance specification 2 in appendix B of this part, collect sulfur
dioxide and oxygen (or carbon dioxide) data concurrently (or within a
30- to 60-minute period) with both the CEMS and the test methods
specified in paragraphs (s)(1)(i) and (ii) of this section:
    (i) For sulfur dioxide, EPA Reference Method 6 or 6C, or as an
alternative ANSI/ASME PTC 19.10-1981 (incorporated by reference, see
Sec.  60.17) must be used; and
    (ii) For oxygen (or carbon dioxide), EPA Reference Method 3A or 3B,
or as an alternative ANSI/ASME PTC 19.10-1981 (incorporated by
reference, see Sec.  60.17), as applicable, must be used.
    (2) The span value of the CEMS at the inlet to the sulfur dioxide
control device must be 125 percent of the maximum estimated hourly

specified in Sec.  60.2730 to measure nitrogen oxides. CEMS data during
startup and shutdown, as defined in this subpart, are not corrected to
7 percent oxygen, and are measured at stack oxygen content. You must
calculate a 30-day rolling average of the 1-hour arithmetic average
emission concentration using equation 19-19 in section 12.4.1 of EPA
Reference Method 19 at 40 CFR part 60, appendix A-7. The nitrogen

nitrogen oxides and oxygen (or carbon dioxide) data concurrently (or
within a 30- to 60-minute period) with both the CEMS and the test
methods specified in paragraphs (t)(1)(i) and (ii) of this section:
    (i) For nitrogen oxides, EPA Reference Method 7 or 7E at 40 CFR
part 60, appendix A-4 must be used; and
    (ii) For oxygen (or carbon dioxide), EPA Reference Method 3A or 3B,
or as an alternative ANSI/ASME PTC 19.10-1981 (incorporated by
reference, see Sec.  60.17), as applicable, must be used.
    (2) The span value of the CEMS must be 125 percent of the maximum
estimated hourly potential nitrogen oxide emissions of unit.
    (3) Conduct accuracy determinations quarterly and calibration drift
tests daily in accordance with procedure 1 in appendix F of this part.
    (4) The owner or operator of an affected facility may request that
compliance with the nitrogen oxides emission limit be determined using
carbon dioxide measurements corrected to an equivalent of 7 percent
oxygen. If carbon dioxide is selected for use in diluent corrections,
the relationship between oxygen and carbon dioxide levels must be
established during the initial performance test according to the
procedures and methods specified in paragraphs (t)(4)(i) through (iv)
of this section. This relationship may be reestablished during
performance compliance tests:
    (i) The fuel factor equation in Method 3B must be used to determine
the relationship between oxygen and carbon dioxide at a sampling
location. Method 3A, 3B, or as an alternative ANSI/ASME PTC 19.10-1981
(incorporated by reference, see Sec.  60.17), as applicable, must be
used to determine the oxygen concentration at the same location as the
carbon dioxide monitor;
    (ii) Samples must be taken for at least 30 minutes in each hour;
    (iii) Each sample must represent a 1-hour average; and
    (iv) A minimum of 3 runs must be performed.

using a 30-day rolling average of 1-hour arithmetic average emission
concentrations, including CEMS data during startup and shutdown, as
defined in this subpart, calculated using equation 19-19 in section
12.4.1 of EPA Reference Method 19 at 40 CFR part 60, appendix A-7. CEMS
data during startup and shutdown, as defined in this subpart, are not
corrected to 7 percent oxygen, and are measured at stack oxygen
content; and
    (2) Operate all CEMS in accordance with the applicable procedures
under appendices B and F of this part.
    (v) Use of the bypass stack at any time is an emissions standards
deviation for particulate matter, HCl, Pb, Cd, Hg, NOX,
SO2, and dioxin/furans.
    (w) For energy recovery units with a design heat input capacity of
100 MMBtu per hour or greater that do not use a carbon monoxide CEMS,
you must install, operate, and maintain an oxygen analyzer system as
defined in Sec.  60.2875 according to the procedures in paragraphs
(w)(1) through (4) of this section:
    (1) The oxygen analyzer system must be installed by the initial
performance test date specified in Sec.  60.2675;
    (2) You must operate the oxygen trim system within compliance with
paragraph (w)(3) of this section at all times;
    (3) You must maintain the oxygen level such that the 30-day rolling
average that is established as the operating limit for oxygen is not

concentration using equation 19-19 in section 12.4.1 of EPA Reference
Method 19 of Appendix A-7 of this part.
    (x) For energy recovery units with annual average heat input rates
greater than or equal to 250 MMBtu/hour and waste-burning kilns, you
must install, calibrate, maintain, and operate a PM CPMS and record the
output of the system as specified in paragraphs (x)(1) through (8) of
this section. For other energy recovery units, you may elect to use PM
CPMS operated in accordance with this section. PM CPMS are suitable in
lieu of using other CMS for monitoring PM compliance (e.g., bag leak
detectors, ESP secondary power, PM scrubber pressure):
    (1) Install, calibrate, operate, and maintain your PM CPMS
according to the procedures in your approved site-specific monitoring
plan developed in accordance with paragraphs (l) and (x)(1)(i) through
(iii) of this section:
    (i) The operating principle of the PM CPMS must be based on in-
stack or extractive light scatter, light scintillation, beta
attenuation, or mass accumulation of the exhaust gas or representative
sample. The reportable measurement output from the PM CPMS must be
expressed as milliamps or the digital signal equivalent;
    (ii) The PM CPMS must have a cycle time (i.e., period required to
complete sampling, measurement, and reporting for each measurement) no
longer than 60 minutes; and
    (iii) The PM CPMS must be capable of detecting and responding to
particulate matter concentrations increments no greater than 0.5 mg/
actual cubic meter.
    (2) During the initial performance test or any such subsequent
performance test that demonstrates compliance with the PM limit, you
must adjust the site-specific operating limit in accordance with the
results of the performance test according to the procedures specified
in Sec.  60.2675.
    (3) Collect PM CPMS hourly average output data for all energy
recovery unit or waste-burning kiln operating hours. Express the PM
CPMS output as milliamps or the digital signal equivalent.
    (4) Calculate the arithmetic 30-day rolling average of all of the
hourly average PM CPMS output collected during all energy recovery unit
or waste-burning kiln operating hours data (milliamps or their digital
equivalent).
    (5) You must collect data using the PM CPMS at all times the energy
recovery unit or waste-burning kiln is operating and at the intervals
specified in paragraph (x)(1)(ii) of this section, except for periods
of monitoring system malfunctions, repairs associated with monitoring
system malfunctions, required monitoring system quality assurance or
quality control activities (including, as applicable, calibration
checks and required zero and span adjustments), and any scheduled
maintenance as defined in your site-specific monitoring plan.
    (6) You must use all the data collected during all energy recovery
unit or waste-burning kiln operating hours in assessing the compliance
with your operating limit except:
    (i) Any data collected during monitoring system malfunctions,
repairs associated with monitoring system malfunctions, or required
monitoring system quality assurance or quality control activities
conducted during monitoring system malfunctions are not used in
calculations (report any such periods in your annual deviation report);
    (ii) Any data collected during periods when the monitoring system
is out of control as specified in your site-specific monitoring plan,
repairs associated with periods when the monitoring system is out of
control, or required monitoring system quality assurance or quality
control activities conducted during out-of-control periods are not used
in calculations (report emissions or operating levels and report any
such periods in your annual deviation report);
    (iii) Any PM CPMS data recorded during periods of CEMS data during
startup and shutdown, as defined in this subpart.
    (7) You must record and make available upon request results of PM
CPMS system performance audits, as well as the dates and duration of
periods from when the PM CPMS is out of control until completion of the
corrective actions necessary to return the PM CPMS to operation
consistent with your site-specific monitoring plan.
    (8) For any deviation of the 30-day rolling average PM CPMS average
value from the established operating parameter limit, you must:
    (i) Within 48 hours of the deviation, visually inspect the air
pollution control device;
    (ii) If inspection of the air pollution control device identifies
the cause of the deviation, take corrective action as soon as possible
and return the PM CPMS measurement to within the established value;
    (iii) Within 30 days of the deviation or at the time of the annual
compliance test, whichever comes first, conduct a PM emissions
compliance test to determine compliance with the PM emissions limit and
to verify. Within 45 days of the deviation, you must re-establish the
CPMS operating limit. You are not required to conduct additional
testing for any deviations that occur between the time of the original
deviation and the PM emissions compliance test required under paragraph
(x) of this section; and
    (iv) PM CPMS deviations leading to more than four required
performance tests in a 12-month process operating period (rolling
monthly) constitute a violation of this subpart.
    (y) When there is an alkali bypass and/or an in-line coal mill that
exhaust emissions through a separate stack(s), the combined emissions
are subject to

the emission limits applicable to waste-burning kilns. To determine the
kiln-specific emission limit for demonstrating compliance, you must:
    (1) Calculate a kiln-specific emission limit using equation 7:
    [GRAPHIC] [TIFF OMITTED] TR23JN16.014

Where:

Cks = Kiln stack concentration (ppmvd, mg/dscm, ng/dscm,
depending on pollutant. Each corrected to 7% O2.)
Qab = Alkali bypass flow rate (volume/hr)
Cab = Alkali bypass concentration (ppmvd, mg/dscm, ng/
dscm, depending on pollutant. Each corrected to 7% O2.)
Qcm = In-line coal mill flow rate (volume/hr)
Ccm = In-line coal mill concentration (ppmvd, mg/dscm,
ng/dscm, depending on pollutant. Each corrected to 7%
O2.)
Qks = Kiln stack flow rate (volume/hr)

    (2) Particulate matter concentration must be measured downstream of
the in-line coal mill. All other pollutant concentrations must be
measured either upstream or downstream of the in-line coal mill.
    (3) For purposes of determining the combined emissions from kilns
equipped with an alkali bypass or that exhaust kiln gases to a coal
mill that exhausts through a separate stack, instead of installing a
CEMS or PM CPMS on the alkali bypass stack or in-line coal mill stack,
the results of the initial and subsequent performance test can be used
to demonstrate compliance with the relevant emissions limit. A
performance test must be conducted on an annual basis (between 11 and
13 calendar months following the previous performance test).

Sec.  60.2715  By what date must I conduct the annual performance test?

    You must conduct annual performance tests between 11 and 13 months
of the previous performance test.

Sec.  60.2716  By what date must I conduct the annual air pollution
control device inspection?

    On an annual basis (no more than 12 months following the previous
annual air pollution control device inspection), you must complete the
air pollution control device inspection as described in Sec.  60.2706.

Sec.  60.2720  May I conduct performance testing less often?

    (a) You must conduct annual performance tests according to the
schedule specified in Sec.  60.2715, with the following exceptions:
    (1) You may conduct a repeat performance test at any time to

forward, as specified in Sec.  60.2725. The Administrator may request a
repeat performance test at any time;
    (2) You must repeat the performance test within 60 days of a
process change, as defined in Sec.  60.2875; and
    (3) If the initial or any subsequent performance test for any
pollutant in table 2 or tables 6 through 9 of this subpart, as
applicable, demonstrates that the emission level for the pollutant is
no greater than the emission level specified in paragraph (a)(3)(i) or
(a)(3)(ii) of this section, as applicable, and you are not required to
conduct a performance test for the pollutant in response to a request
by the Administrator in paragraph (a)(1) of this section or a process
change in paragraph (a)(2) of this section, you may elect to skip
conducting a performance test for the pollutant for the next 2 years.
You must conduct a performance test for the pollutant during the third
year and no more than 37 months following the previous performance test
for the pollutant. For cadmium and lead, both cadmium and lead must be
emitted at emission levels no greater than their respective emission
levels specified in paragraph (a)(3)(i) of this section for you to
qualify for less frequent testing under paragraph (a) of this section:
    (i) For particulate matter, hydrogen chloride, mercury, carbon
monoxide, nitrogen oxides, sulfur dioxide, cadmium, lead, and dioxins/
furans, the emission level equal to 75 percent of the applicable
emission limit in table 2 or tables 6 through 9 of this subpart, as
applicable, to this subpart; and
    (ii) For fugitive emissions, visible emissions (of combustion ash
from the ash conveying system) for 2 percent of the time during each of
the three 1-hour observation periods.
    (4) If you are conducting less frequent testing for a pollutant as
provided in paragraph (a)(3) of this section and a subsequent
performance test for the pollutant indicates that your CISWI unit does
not meet the emission level specified in paragraph (a)(3)(i) or
(a)(3)(ii) of this section, as applicable, you must conduct annual
performance tests for the pollutant according to the schedule specified
in paragraph (a) of this section until you qualify for less frequent
testing for the pollutant as specified in paragraph (a)(3) of this
section.
    (b) [Reserved]

Sec.  60.2725  May I conduct a repeat performance test to establish new
operating limits?

    (a) Yes. You may conduct a repeat performance test at any time to
establish new values for the operating limits. The Administrator may
request a repeat performance test at any time.
    (b) You must repeat the performance test if your feed stream is
different than the feed streams used during any performance test used
to demonstrate compliance.

    (1) Following the date on which the initial performance test is
completed or is required to be completed under Sec.  60.2690, whichever
date comes first, ensure that the affected facility does not operate
above the maximum charge rate, or below the minimum secondary chamber
temperature (if applicable to your CISWI unit) or the minimum reagent
flow rate measured as 3-hour block averages at all times; and
    (2) Operation of the affected facility above the maximum charge
rate, below the minimum secondary chamber temperature and below the
minimum reagent flow rate simultaneously constitute a violation of the
nitrogen oxides emissions limit.
    (f) If you use an electrostatic precipitator to comply with the
emission limits of this subpart and you do not use a PM CPMS for
monitoring PM compliance, you must monitor the secondary power to the
electrostatic precipitator collection plates and maintain the 3-hour
block averages at or above the operating limits established during the
mercury or particulate matter performance test.
    (g) For waste-burning kilns not equipped with a wet scrubber or dry
scrubber, in place of hydrogen chloride testing with EPA Method 321 at
40 CFR part 63, appendix A, an owner or operator must install,
calibrate, maintain, and operate a CEMS for monitoring hydrogen
chloride emissions, as specified in Sec.  60.2710(j), discharged to the
atmosphere and record the output of the system. To demonstrate
continuous compliance with the hydrogen chloride emissions limit for
units other than waste-burning kilns not equipped with a wet scrubber
or dry scrubber, a facility may substitute use of a hydrogen chloride
CEMS for conducting the hydrogen chloride annual performance test,
monitoring the minimum hydrogen chloride sorbent flow rate, monitoring
the minimum scrubber liquor pH.
    (h) To demonstrate continuous compliance with the particulate
matter emissions limit, a facility may substitute use of either a
particulate matter CEMS or a particulate matter CPMS for conducting the
particulate matter annual performance test and other CMS monitoring for
PM compliance (e.g., bag leak detectors, ESP secondary power, PM
scrubber pressure).
    (i) To demonstrate continuous compliance with the dioxin/furan
emissions limit, a facility may substitute use of a continuous
automated sampling system for the dioxin/furan annual performance test.
You must record the output of the system and analyze the sample
according to EPA Method 23 at 40 CFR part 60, appendix A-7. This option
to use a continuous automated sampling system takes effect on the date
a final performance specification applicable to dioxin/furan from
continuous monitors is published in the Federal Register. The owner or
operator who elects to continuously sample dioxin/furan emissions
instead of sampling and testing using EPA Method 23 at 40 CFR part 60,
appendix A-7 must install, calibrate, maintain and operate a continuous
automated sampling system and must comply with the requirements
specified in Sec.  60.58b(p) and (q). A facility may substitute
continuous dioxin/furan monitoring for the minimum sorbent flow rate,
if activated carbon sorbent injection is used solely for compliance
with the dioxin/furan emission limit.
    (j) To demonstrate continuous compliance with the mercury emissions
limit, a facility may substitute use of a continuous automated sampling
system for the mercury annual performance test. You must record the
output of the system and analyze the sample at set intervals using any
suitable determinative technique that can meet performance
specification 12B criteria. This option to use a continuous automated
sampling system takes effect on the date a final performance
specification applicable to mercury from monitors is published in the
Federal Register. The owner or operator who elects to continuously
sample mercury emissions instead of sampling and testing using EPA
Method 29 or 30B at 40 CFR part 60, appendix A-8, ASTM D6784-02
(Reapproved 2008) (incorporated by reference, see Sec.  60.17), or an
approved alternative method for measuring mercury emissions, must
install, calibrate, maintain and operate a continuous automated
sampling system and must comply with the requirements specified in
Sec.  60.58b(p) and (q). A facility may substitute continuous mercury
monitoring for the minimum sorbent flow rate, if activated carbon
sorbent injection is used solely for compliance with the mercury
emission limit. Waste-burning kilns must install, calibrate, maintain,
and operate a mercury CEMS as specified in Sec.  60.2710(j).
    (k) To demonstrate continuous compliance with the nitrogen oxides
emissions limit, a facility may substitute use of a CEMS for the
nitrogen oxides annual performance test to demonstrate compliance with
the nitrogen oxides emissions limits and monitoring the charge rate,
secondary chamber temperature and reagent flow for selective
noncatalytic reduction, if applicable:
    (1) Install, calibrate, maintain and operate a CEMS for measuring
nitrogen oxides emissions discharged to the atmosphere and record the
output of the system. The requirements under performance specification
2 of appendix B of this part, the quality assurance procedure 1 of
appendix F of this part and the procedures under Sec.  60.13 must be
followed for installation, evaluation and operation of the CEMS; and
    (2) Following the date that the initial performance test for
nitrogen oxides is completed or is required to be completed under Sec.
60.2690, compliance with the emission limit for nitrogen oxides
required under Sec.  60.52b(d) must be determined based on the 30-day
rolling average of the hourly emission concentrations using CEMS outlet
data. The 1-hour arithmetic averages must be expressed in parts per
million by volume corrected to 7 percent oxygen (dry basis) and used to
calculate the 30-day rolling average concentrations.

CEMS data during startup and shutdown, as defined in this subpart, are
not corrected to 7 percent oxygen, and are measured at stack oxygen
content. The 1-hour arithmetic averages must be calculated using the
data points required under Sec.  60.13(e)(2).
    (l) To demonstrate continuous compliance with the sulfur dioxide
emissions limit, a facility may substitute use of a continuous
automated sampling system for the sulfur dioxide annual performance
test to demonstrate compliance with the sulfur dioxide emissions
limits:
    (1) Install, calibrate, maintain and operate a CEMS for measuring
sulfur dioxide emissions discharged to the atmosphere and record the
output of the system. The requirements under performance specification
2 of appendix B of this part, the quality assurance requirements of
procedure 1 of appendix F of this part and the procedures under Sec.
60.13 must be followed for installation, evaluation and operation of
the CEMS; and
    (2) Following the date that the initial performance test for sulfur
dioxide is completed or is required to be completed under Sec.
60.2690, compliance with the sulfur dioxide emission limit may be
determined based on the 30-day rolling average of the hourly arithmetic
average emission concentrations using CEMS outlet data. The 1-hour
arithmetic averages must be expressed in parts per million corrected to
7 percent oxygen (dry basis) and used to calculate the 30-day rolling
average emission concentrations. CEMS data during startup and shutdown,
as defined in this subpart, are not corrected to 7 percent oxygen, and
are measured at stack oxygen content. The 1-hour arithmetic averages
must be calculated using the data points required under Sec.
60.13(e)(2).
    (m) For energy recovery units over 10 MMBtu/hr but less than 250
MMBtu/hr annual average heat input rates that do not use a wet
scrubber, fabric filter with bag leak detection system, or particulate
matter CEMS, you must install, operate, certify and maintain a
continuous opacity monitoring system according to the procedures in
paragraphs (m)(1) through (5) of this section by the compliance date
specified in Sec.  60.2670. Energy recovery units that use a
particulate matter CEMS to demonstrate initial and continuing
compliance according to the procedures in Sec.  60.2730(n) are not
required to install a continuous opacity monitoring system and must
perform the annual performance tests for opacity consistent with Sec.
60.2710(f):
    (1) Install, operate and maintain each continuous opacity
monitoring system according to performance specification 1 at 40 CFR
part 60, appendix B;

monitoring system according to the requirements in Sec.  60.13 and
according to performance specification 1 at 40 CFR part 60, appendix B;
    (3) As specified in Sec.  60.13(e)(1), each continuous opacity
monitoring system must complete a minimum of one cycle of sampling and
analyzing for each successive 10-second period and one cycle of data
recording for each successive 6-minute period;
    (4) Reduce the continuous opacity monitoring system data as
specified in Sec.  60.13(h)(1); and
    (5) Determine and record all the 6-minute averages (and 1-hour
block averages as applicable) collected.
    (n) For coal and liquid/gas energy recovery units, incinerators,
and small remote incinerators, an owner or operator may elect to
install, calibrate, maintain and operate a CEMS for monitoring
particulate matter emissions discharged to the atmosphere and record
the output of the system. The owner or operator of an affected facility
who continuously monitors particulate matter emissions instead of
conducting performance testing using EPA Method 5 at 40 CFR part 60,
appendix A-3 or, as applicable, monitor with a particulate matter CPMS
according to paragraph (r) of this section, must install, calibrate,
maintain and operate a CEMS and must comply with the requirements
specified in paragraphs (n)(1) through (13) of this section:
    (1) Notify the Administrator 1 month before starting use of the
system;
    (2) Notify the Administrator 1 month before stopping use of the
system;
    (3) The monitor must be installed, evaluated and operated in
accordance with the requirements of performance specification 11 of
appendix B of this part and quality assurance requirements of procedure

than 180 days after the final compliance date for meeting the amended
emission limitations, as specified under Sec.  60.2690 or within 180
days of notification to the Administrator of use of the continuous
monitoring system if the owner or operator was previously determining
compliance by Method 5 at 40 CFR part 60, appendix A-3 performance
tests, whichever is later;
    (5) The owner or operator of an affected facility may request that
compliance with the particulate matter emission limit be determined
using carbon dioxide measurements corrected to an equivalent of 7
percent oxygen. The relationship between oxygen and carbon dioxide
levels for the affected facility must be established according to the
procedures and methods specified in Sec.  60.2710(t)(4)(i) through
(iv);
    (6) The owner or operator of an affected facility must conduct an
initial performance test for particulate matter emissions as required
under Sec.  60.2690. Compliance with the particulate matter emission
limit, if PM CEMS are elected for demonstrating compliance, must be
determined by using the CEMS specified in paragraph (n) of this section
to measure particulate matter. You must calculate a 30-day rolling
average of 1-hour arithmetic average emission concentrations, including
CEMS data during startup and shutdown, as defined in this subpart,
using equation 19-19 in section 12.4.1 of EPA Reference Method 19 at 40
CFR part 60, appendix A-7 of this part;
    (7) Compliance with the particulate matter emission limit must be
determined based on the 30-day rolling average calculated using
equation 19-19 in section 12.4.1 of EPA Reference Method 19 at 40 CFR
part 60, Appendix A-7 of the part from the 1-hour arithmetic average of
the CEMS outlet data.
    (8) At a minimum, valid continuous monitoring system hourly
averages must be obtained as specified Sec.  60.2735;
    (9) The 1-hour arithmetic averages required under paragraph (n)(7)
of this section must be expressed in milligrams per dry standard cubic
meter corrected to 7 percent oxygen (or carbon dioxide) (dry basis) and
must be used to calculate the 30-day rolling average emission
concentrations. CEMS data during startup and shutdown, as defined in

at stack oxygen content. The 1-hour arithmetic averages must be
calculated using the data points required under Sec.  60.13(e)(2);
    (10) All valid CEMS data must be used in calculating average
emission concentrations even if the minimum CEMS data requirements of
paragraph (n)(8) of this section are not met;
    (11) The CEMS must be operated according to performance
specification 11 in appendix B of this part;
    (12) During each relative accuracy test run of the CEMS required by
performance specification 11 in appendix B of this part, particulate
matter and oxygen (or carbon dioxide) data must be collected
concurrently (or within a 30-to 60-minute period) by both the CEMS and
the following test methods:

    (i) For particulate matter, EPA Reference Method 5 at 40 CFR part
60, appendix A-3 must be used; and
    (ii) For oxygen (or carbon dioxide), EPA Reference Method 3A or 3B
at 40 CFR part 60, appendix A-2, as applicable, must be used; and
    (13) Quarterly accuracy determinations and daily calibration drift

followed for installation, evaluation, and operation of the CEMS; and
    (2) Following the date that the initial performance test for carbon
monoxide is completed or is required to be completed under Sec.
60.2690, compliance with the carbon monoxide emission limit may be
determined based on the 30-day rolling average of the hourly arithmetic
average emission concentrations, including CEMS data during startup and
shutdown as defined in this subpart, using CEMS outlet data. Except for
CEMS data during startup and shutdown, as defined in this subpart, the
1-hour arithmetic averages must be expressed in parts per million
corrected to 7 percent oxygen (dry basis) and used to calculate the 30-
day rolling average emission concentrations. CEMS data collected during
startup or shutdown, as defined in this subpart, are not corrected to 7
percent oxygen, and are measured at stack oxygen content. The 1-hour
arithmetic averages must be calculated using the data points required
under Sec.  60.13(e)(2).
    (p) The owner/operator of an affected source with a bypass stack
shall install, calibrate (to manufacturers' specifications), maintain
and operate a device or method for measuring the use of the bypass
stack including date, time and duration.
    (q) For energy recovery units with a heat input capacity of 100
MMBtu per hour or greater that do not use a carbon monoxide CEMS, you

greater than or equal to 250 MMBtu/hour and waste-burning kilns, you
must install, calibrate, maintain, and operate a PM CPMS and record the
output of the system as specified in paragraphs (r)(1) through (8) of
this section. For other energy recovery units, you may elect to use PM
CPMS operated in accordance with this section. PM CPMS are suitable in
lieu of using other CMS for monitoring PM compliance (e.g., bag leak
detectors, ESP secondary power, PM scrubber pressure):
    (1) Install, calibrate, operate, and maintain your PM CPMS
according to the procedures in your approved site-specific monitoring
plan developed in accordance with Sec.  60.2710(l) and (r)(1)(i)
through (iii) of this section:
    (i) The operating principle of the PM CPMS must be based on in-
stack or extractive light scatter, light scintillation, beta
attenuation, or mass accumulation of the exhaust gas or representative
sample. The reportable measurement output from the PM CPMS must be

must adjust the site-specific operating limit in accordance with the
results of the performance test according to the procedures specified
in Sec.  60.2675.
    (3) Collect PM CPMS hourly average output data for all energy
recovery unit or waste-burning kiln operating hours. Express the PM
CPMS output as milliamps or the digital signal equivalent.
    (4) Calculate the arithmetic 30-day rolling average of all of the
hourly average PM CPMS output collected during all energy recovery unit
or waste-burning kiln operating hours data (milliamps or digital bits).
    (5) You must collect data using the PM CPMS at all times the energy
recovery unit or waste-burning kiln is operating and at the intervals
specified in paragraph (r)(1)(ii) of this section, except for periods
of monitoring system malfunctions, repairs associated with monitoring
system malfunctions, required monitoring system quality assurance or
quality control activities (including, as applicable, calibration
checks and required zero and span adjustments), and any scheduled
maintenance as defined in your site-specific monitoring plan.
    (6) You must use all the data collected during all energy recovery
unit or waste-burning kiln operating hours in assessing the compliance
with your operating limit except:
    (i) Any data collected during monitoring system malfunctions,
repairs associated with monitoring system malfunctions, or required
monitoring system quality assurance or quality control activities
conducted during monitoring system malfunctions are not used in
calculations (report any such periods in your annual deviation report);
    (ii) Any data collected during periods when the monitoring system
is out of control as specified in your site-specific monitoring plan,
repairs associated with periods when the monitoring system is out of
control, or required monitoring system quality assurance or quality
control activities conducted during out-of-control periods are not used
in calculations (report emissions or operating levels and report any
such periods in your annual deviation report); and
    (iii) Any PM CPMS data recorded during periods of CEMS data during
startup and shutdown, as defined in this subpart.
    (7) You must record and make available upon request results of PM
CPMS system performance audits, as well as the dates and duration of
periods from when the PM CPMS is out of control until completion of the
corrective actions necessary to return

the PM CPMS to operation consistent with your site-specific monitoring
plan.
    (8) For any deviation of the 30-day rolling average PM CPMS average
value from the established operating parameter limit, you must:
    (i) Within 48 hours of the deviation, visually inspect the air
pollution control device;
    (ii) If inspection of the air pollution control device identifies
the cause of the deviation, take corrective action as soon as possible
and return the PM CPMS measurement to within the established value;
    (iii) Within 30 days of the deviation or at the time of the annual
compliance test, whichever comes first, conduct a PM emissions
compliance test to determine compliance with the PM emissions limit and
to verify the operation of the emissions control device(s). Within 45
days of the deviation, you must re-establish the CPMS operating limit.
You are not required to conduct additional testing for any deviations
that occur between the time of the original deviation and the PM
emissions compliance test required under this paragraph; and
    (iv) PM CPMS deviations leading to more than four required
performance tests in a 12-month process operating period (rolling
monthly) constitute a violation of this subpart.
    (s) If you use a dry scrubber to comply with the emission limits of
this subpart, you must monitor the injection rate of each sorbent and
maintain the 3-hour block averages at or above the operating limits
established during the hydrogen chloride performance test.

Sec.  60.2735  Is there a minimum amount of monitoring data I must
obtain?

    For each continuous monitoring system required or optionally
allowed under Sec.  60.2730, you must monitor and collect data
according to this section:
    (a) You must operate the monitoring system and collect data at all
required intervals at all times compliance is required except for
periods of monitoring system malfunctions or out-of-control periods,
repairs associated with monitoring system malfunctions or out-of-
control periods (as specified in Sec.  60.2770(o)), and required
monitoring system quality assurance or quality control activities
including, as applicable, calibration checks and required zero and span
adjustments. A monitoring system malfunction is any sudden, infrequent,
not reasonably preventable failure of the monitoring system to provide
valid data. Monitoring system failures that are caused in part by poor
maintenance or careless operation are not malfunctions. You are
required to effect monitoring system repairs in response to monitoring
system malfunctions or out-of-control periods and to return the
monitoring system to operation as expeditiously as practicable.
    (b) You may not use data recorded during the monitoring system
malfunctions, repairs associated with monitoring system malfunctions or
out-of control periods, or required monitoring system quality assurance
or control activities in calculations used to report emissions or
operating levels. You must use all the data collected during all other
periods, including data normalized for above scale readings, in
assessing the operation of the control device and associated control
system.
    (c) Except for periods of monitoring system malfunctions or out-of-
control periods, repairs associated with monitoring system malfunctions
or out-of-control periods, and required monitoring system quality
assurance or quality control activities including, as applicable,
calibration checks and required zero and span adjustments, failure to
collect required data is a deviation of the monitoring requirements.

Model Rule--Definitions

Sec.  60.2875  What definitions must I know?

    Terms used but not defined in this subpart are defined in the Clean
Air Act and subparts A and B of this part.
    30-day rolling average means the arithmetic mean of the previous
720 hours of valid operating data. Valid data excludes periods when
this unit is not operating. The 720 hours should be consecutive, but
not necessarily continuous if operations are intermittent.
    Administrator means the Administrator of the U.S. Environmental
Protection Agency or his/her authorized representative or Administrator
of a State Air Pollution Control Agency.
    Agricultural waste means vegetative agricultural materials such as
nut and grain hulls and chaff (e.g., almond, walnut, peanut, rice, and
wheat), bagasse, orchard prunings, corn stalks, coffee bean hulls and
grounds, and other vegetative waste materials generated as a result of
agricultural operations.
    Air curtain incinerator means an incinerator that operates by
forcefully projecting a curtain of air across an open chamber or pit in
which combustion occurs. Incinerators of this type can be constructed
above or below ground and with or without refractory walls and floor.
(Air curtain incinerators are not to be confused with conventional
combustion devices with enclosed fireboxes and controlled air
technology such as mass burn, modular, and fluidized bed combustors.)
    Annual heat input means the heat input for the 12 months preceding
the compliance demonstration.
    Auxiliary fuel means natural gas, liquified petroleum gas, fuel
oil, or diesel fuel.
    Average annual heat input rate means annual heat input divided by
the hours of operation for the 12 months preceding the compliance
demonstration.
    Bag leak detection system means an instrument that is capable of
monitoring particulate matter loadings in the exhaust of a fabric
filter (i.e., baghouse) in order to detect bag failures. A bag leak
detection system includes, but is not limited to, an instrument that
operates on triboelectric, light scattering, light transmittance, or
other principle to monitor relative particulate matter loadings.
    Burn-off oven means any rack reclamation unit, part reclamation
unit, or drum reclamation unit. A burn-off oven is not an incinerator,
waste-burning kiln, an energy recovery unit or a small, remote
incinerator under this subpart.
    Bypass stack means a device used for discharging combustion gases
to avoid severe damage to the air pollution control device or other
equipment.
    Calendar quarter means three consecutive months (nonoverlapping)
beginning on: January 1, April 1, July 1, or October 1.
    Calendar year means 365 consecutive days starting on January 1 and
ending on December 31.
    CEMS data during startup and shutdown means the following:
    (1) For incinerators and small remote incinerators: CEMS data
collected during the first hours of operation of a CISWI unit startup
from a cold start until waste is fed into the unit and the hours of
operation following the cessation of waste material being fed to the
CISWI unit during a unit shutdown. For each startup event, the length
of time that CEMS data may be claimed as being CEMS data during startup
must be 48 operating hours or less. For each shutdown event, the length
of time that CEMS data may be claimed as being CEMS data during
shutdown must be 24 operating hours or less;
    (2) For energy recovery units: CEMS data collected during the
startup or shutdown periods of operation. Startup begins with either
the first-ever firing of fuel in a boiler or process heater for the
purpose of supplying useful thermal energy (such as steam or heat) for
heating, cooling or process purposes, or producing electricity, or the
firing of fuel in a boiler or process heater for any purpose after a
shutdown event. Startup ends four hours after when the boiler or
process heater makes useful thermal energy (such as heat or steam) for
heating, cooling, or process purposes, or generates electricity,
whichever is earlier. Shutdown begins when the boiler or process heater
no longer makes useful thermal energy (such as heat or steam) for
heating, cooling, or process purposes and/or generates electricity or
when no fuel is being fed to the boiler or process heater, whichever is
earlier. Shutdown ends when the boiler or process heater no longer
makes useful thermal energy (such as steam or heat) for heating,
cooling, or process purposes and/or generates electricity, and no fuel
is being combusted in the boiler or process heater; and
    (3) For waste-burning kilns: CEMS data collected during the periods
of kiln operation that do not include normal operations. Startup means
the time from when a shutdown kiln first begins firing fuel until it
begins producing clinker. Startup begins when a shutdown kiln turns on
