The EPA continues to carefully and continuously monitor information
from the Centers for Disease Control and Prevention (CDC), local area
health departments, and our Federal partners so that we can respond
rapidly as conditions change regarding COVID-19.
II. General Information
A. Does this action apply to me?
The proposed amendments apply to industries that are subject to the
current provisions of 40 CFR parts 51, 60, and 63. We did not list all
of the specific affected industries or their North American Industry
Classification
[[Page 24490]]
System (NAICS) codes herein since there are many affected sources in
numerous NAICS categories. If you have any questions regarding the
applicability of this action to a particular entity, consult either the
air permitting authority for the entity or your EPA Regional
representative as listed in 40 CFR 63.13.
B. What action is the Agency taking?
This action proposes corrections and revisions to source test
methods, performance specifications (PS), and associated regulations.
The corrections and revisions consist primarily of typographical
errors, updates to testing procedures, and the addition of alternative
equipment and methods the Agency has deemed acceptable to use.
III. Background
The EPA catalogs errors and corrections, as well as necessary
revisions to test methods, performance specifications, and associated
regulations in 40 CFR parts 51, 60, and 63 and periodically updates and
revises these provisions. The most recent updates and revisions were
promulgated on October 7, 2020 (85 FR 63394). This proposed rule
addresses necessary corrections and revisions identified after that
final action, many of which were brought to our attention by regulated
sources and end-users, such as environmental consultants and compliance
professionals. These revisions will improve the quality of data
obtained and give source testers the flexibility to use newly approved
alternative procedures.
IV. Incorporation by Reference
The EPA proposes to incorporate by reference two ASTM standards.
Specifically, the EPA proposes to incorporate ASTM D6216-20, which
covers the procedure for certifying continuous opacity monitors and
includes design and performance specifications, test procedures, and QA
requirements to ensure that continuous opacity monitors meet minimum
design and calibration requirements necessary for accurate opacity
monitoring measurements in regulatory environmental opacity monitoring
applications subject to 10 percent or higher opacity standards. The EPA
also proposes to update the incorporation by reference for ASTM D6784,
a test method for elemental, oxidized, particle-bound, and total
mercury in emissions from stationary sources, from the 2002 version to
the 2016 version; this update would apply to incorporations by
reference in 40 CFR part 60, appendix B, Performance Specification 12A
for continuous monitoring of mercury emissions. Likewise, EPA proposes
to update the incorporations by reference in 40 CFR part 63 for use of
ASTM D6784 under table 5 and appendix A of Subpart UUUUU, for mercury
emissions measurement and monitoring. Both the ASTM D6216-20 and ASTM
D6784-16 standards were developed and adopted by ASTM. The ASTM
standards may be obtained from www.astm.org or from the ASTM at 100
Barr Harbor Drive, P.O. Box C700, West Conshohocken, PA 19428-2959.
The EPA also proposes to incorporate by reference the American
Public Health Association (APHA) Method 5210 Biochemical Oxygen Demand
(BOD) from ``Standard Methods for the Examination of Water and
Wastewater.'' This standard is acceptable as an alternative to Method
405.1 and is available from APHA at www.standardmethods.org or by
telephone at (844) 232-3707.
The EPA is also proposing specific modifications to requirements in
an existing incorporation by reference, the ASTM E2515-11 test method.
The proposed stipulations would modify the post-test leak check
procedures as well as add procedures for performing leak checks during
a sampling run.
V. Summary of Proposed Amendments
The following amendments are being proposed.
A. Method 201A of Appendix M of Part 51
In Method 201A, the erroneous equation 25 in section 12.5 would be
corrected.
B. General Provisions (Subpart A) of Part 60
In the General Provisions of part 60, Sec. 60.17(h) would be
revised to add American Society for Testing and Materials (ASTM) D6216-
20 and D6784-16 to the list of incorporations by reference and to re-
number the remaining consensus standards that are incorporated by
reference in alpha-numeric order.
C. Standards of Performance for New Residential Wood Heaters (Subpart
AAA) of Part 60
Subpart AAA would be amended to add stipulations for use of the
ASTM E2515-11 test method. The stipulations would modify the post-test
leak check procedures as well as add procedures for performing leak
checks during a sampling run. The stipulations to ASTM E2515-11 are
necessary as we have learned that the quality assurance/quality control
(QA/QC) requirements for leak tests required by ASTM E2515-11, section
9.6.5.1 are not sufficient to provide assurance of the sampling system
integrity. Additionally, the language of ASTM E2515-11, section 9.6.5.1
currently allows for averaging the PM results from a non-leaking
sampling system with those from a leaking sampling system, which
effectively reduces reported PM emissions by as much as half, rendering
the test method inappropriate for compliance determination.
We would revise the language in Sec. 60.534(c) and are proposing
new language to replace ASTM E2515-11, section 9.6.5.1 by adding Sec.
60.534(c)(1), which specifies appropriate post-test leak check
procedures and in Sec. 60.534(c)(2) by adding procedures for
performing leak checks during a sampling run. We are proposing these
modifications to bring appropriate QA/QC requirements to PM
measurements required by the rule and to eliminate opportunity for
emissions test results to be considered valid when a leaking sampling
system allows dilution of the PM sample(s).
We are also proposing in Sec. 60.534(d) that the first hour PM
emissions measurements be conducted using a separate ASTM E2515-11
sampling train operated concurrently with the paired ASTM E2515-11
sampling trains used in compliance PM sampling. In this manner, the
first hour PM emissions would be collected appropriately, and the
compliance test measurements would not be impacted by a sampling pause
for filter replacement at the 1-hour mark.
The regulatory language in Sec. 60.539b(b) would be revised to
include General Provisions that were added to Sec. 60.8(f)(2) (81 FR
59801, August 30, 2016) and were inadvertently exempted from inclusion
in subpart AAA as that rule, as promulgated in 2015, exempted Sec.
60.8(f) in its entirety. The exemption promulgated in subpart AAA at
Sec. 60.539b(b) was intended to exempt those affected sources from
Sec. 60.8(f), which, at the time, consisted of what is now currently
Sec. 60.8(f)(1) and is specific to compliance testing results
consisting of the arithmetic mean of three replicate tests. We are
proposing these modifications to ensure that emissions test reporting
includes all data necessary to assess and assure the quality of the
reported emissions data and appropriately describes and identifies the
specific unit covered by the emissions test report. Since compliance
tests in this category consist of a single test, the original
regulatory
[[Page 24491]]
exemption to the General Provisions of Sec. 60.8(f)(1) is retained.
D. Standards of Performance for New Residential Wood Heaters, New
Residential Hydronic Heaters, and Forced-Air Furnaces (Subpart QQQQ) of
Part 60
The erroneous PM emission limits in g/MJ in Sec. Sec.
60.5474(b)(2), (b)(3) and (b)(6) would be corrected.
In addition, subpart QQQQ would be amended to add stipulations for
use of the ASTM E2515-11 test method. The stipulations would modify the
post-test leak check procedures as well as add procedures for
performing leak checks during a sampling run. The stipulations to ASTM
E2515-11 are necessary as we have learned that the QA/QC requirements
for leak tests required by ASTM E2515-11, section 9.6.5.1 are not
sufficient to provide assurance of the sampling system integrity.
Additionally, the language of ASTM E2515-11, section 9.6.5.1 currently
allows for averaging the PM results from a non-leaking sampling system
with those from a leaking sampling system, which effectively reduces
reported PM emissions by as much as half, rendering the test method
inappropriate for compliance determination. The language in Sec.
60.5476(c)(5) and Sec. 60.5476(c)(6) would be replaced with the word
``reserved.''
We would revise language in Sec. 60.5476(f) and are proposing new
language to replace ASTM E2515-11, section 9.6.5.1 by adding Sec.
60.5476(f)(1), which specifies appropriate post-test leak check
procedures and in Sec. 60.5476(f)(2) adding procedures for performing
leak checks during a sampling run. We are proposing these modifications
to bring appropriate QA/QC requirements to PM measurements required by
the rule and eliminate opportunity for emissions test results to be
considered valid when a leaking sampling system allows dilution of the
PM sample(s).
We are also proposing in Sec. 60.5476(f) that first hour PM
emissions measurements should be conducted using a separate ASTM E2515-
11 sampling train operated concurrently with the paired ASTM E2515-11
sampling trains used in compliance PM sampling. In this manner, the
first hour PM emissions will be collected appropriately, and the
compliance test measurements would not be impacted by a sampling pause
for filter replacement at the one-hour mark. In Sec. 60.5476(f), we
would incorporate language about filter type and size acceptance
currently in Sec. 60.5476(c)(5). Additionally, we would remove text
relating to EN 303-5 currently found in Sec. 60.5476(f).
The regulatory language in Sec. 60.5483(b) would be revised to
include General Provisions that were added to Sec. 60.8(f)(2) (81 FR
59801, August 30, 2016) and were inadvertently exempted from subpart
QQQQ as that rule, as promulgated in 2015, exempted Sec. 60.8(f) in
its entirety. The exemption promulgated in subpart QQQQ at Sec.
60.5483(b) was intended for those affected sources subject to Sec.
60.8(f), which, at the time, consisted of what is currently Sec.
60.8(f)(1) and is specific to compliance testing results consisting of
the arithmetic mean of three replicate tests. We are proposing these
modifications to ensure that emissions test reporting includes all data
necessary to assess and assure the quality of the reported emissions
data and appropriately describes and identifies the specific unit
covered by the emissions test report. Since compliance tests in this
category consist of a single test, the original regulatory exemption to
the General Provisions of Sec. 60.8(f)(1) is retained.
In subpart QQQQ, in Method 28WHH, in section 13.8, the erroneous CO
calculation instructions for equation 23 would be corrected to include
the summation of CO emissions over four instead of three test
categories.
E. Method 1 of Appendix A-1 of Part 60
In Method 1, the heading in section 11.5.1 would be moved to 11.5,
and the word ``procedure'' would be moved to the first sentence in
section 11.5.1 for clarity. Section 11.5.2 would be revised to clearly
specify the number of traverse points that must be used for sampling
and velocity measurements once a directional flow-sensing probe
procedure has been used to demonstrate that an alternative measurement
site is acceptable. The last sentence of section 11.5.2, which appears
unclear as to what ``same traverse point number and locations'' it is
referring, would be revised to instead specify the ``same minimum of 40
traverse points for circular ducts and 42 points for rectangular
ducts'' that are used in the alternative measurement procedure of
section 11.5.3.
Also, Table 1-2 would be revised to correct the erroneous
requirement that calls for 99.9 percent of stack diameter from the
inside wall to the traverse point to 98.9 percent.
F. Method 4 of Appendix A-3 of Part 60
In Method 4, Table 4-3 would be formatted correctly.
G. Method 7 of Appendix A-4 of Part 60
In Method 7, section 10.1.3 would be revised to change the word
``should'' to ``shall'' in the last sentence because the difference
between the calculated concentration values and the actual
concentrations are required to be less than 7 percent for all
standards.
H. Method 19 of Appendix A-7 of Part 60
In Method 19, the erroneous equation 19-5 would be corrected.
I. Method 25 of Appendix A-7 of Part 60
In Method 25, a record and report section (section 12.9) would be
added to confirm that the quality control (QC) was successfully
performed. Also, the erroneous Figure 25-6 would be corrected.
J. Method 25C of Appendix A-7 of Part 60
In Method 25C, the nomenclature in section 12.1 for CN2
and CmN2 would be revised to provide clarity.
K. Method 26 of Appendix A-8 of Part 60
In Method 26, erroneous equations 26-4 and 26-5 in sections 12.4
and 12.5, respectively, would be revised to be consistent with the
nomenclature in section 12.1.
L. Performance Specification 1 of Appendix B of Part 60
In Performance Specification 1, references to ASTM D6216-12 (in
sections 2.1, 3.1, 6.1, 8.1(1), 8.1(2)(iii), 8.1(3)(ii), 8.2(1),
8.2(2), 8.2(3), 9.0, 12.1, 13.1, 13.2, and 16.0 reference 8) would be
replaced with ASTM D6216-20. Note: If the initial certification of the
continuous opacity monitoring system (COMS) has already occurred using
D6216-98, D6216-03, D6216-07, or D6216-12, it will not be necessary to
recertify using D6216-20.
Also, in Performance Specification 1, section 8.1(2)(iii) would be
revised by removing the next to the last sentence, which reads, ``The
opacities of the two locations or paths may be measured at different
times but must represent the same process operating conditions,''
because the statement is confusing and unclear; furthermore, it is
unlikely that one would achieve the same conditions at two different
times.
M. Performance Specification 2 of Appendix B of Part 60
In Performance Specification 2, in section 8.3.3, a sentence would
be added to clarify that during a calibration, the reference gas is to
be
[[Page 24492]]
introduced into the sampling system prior to any sample conditioning or
filtration equipment and must pass through as much of the probe as is
practical. In section 12.5, minor revisions would be made to clarify
that relative accuracy (RA) test results are expressed as a percent of
emission rate or concentration (units of the applicable standard) and
the definition of the average reference method (RM) value for Equation
2-6.
N. Performance Specification 4B of Appendix B of Part 60
The entire Performance Specification 4B would be updated to the
Environmental Monitoring Management Council (EMMC) methods format used
for all other performance specifications.
O. Performance Specification 6 of Appendix B of Part 60
In Performance Specification 6, section 13.2 would be revised to
specifically state the relative accuracy criteria including significant
figures. On October 7, 2020 (85 FR 63394), we revised section 13.2 of
Performance Specification 6 to make the relative accuracy calculations
and criteria consistent with Performance Specification 2 and offer an
alternate calculation and criterion for low emission concentration/rate
situations; however, we neglected to specifically cite the alternate
relative accuracy criterion from Performance Specification 2 for low
emission sources and to ensure consistency with Performance
Specification 2 with regard to significant figures in the relative
accuracy criteria.
P. Performance Specification 12A of Appendix B of Part 60
We are proposing to revise the references (in sections 8.4.2,
8.4.4, 8.4.5, 8.4.6.1, and 17.5 and the footnote to Figure 12A-3) to
ASTM D6784, Standard Test Method for Elemental, Oxidized, Particle-
Bound and Total Mercury in Flue Gas Generated from Coal-Fired
Stationary Sources (Ontario Hydro Method), to update them from the 2002
version to the latest version, which was authorized in 2016.
The capabilities of mercury CEMS have been improving since
initially being deployed to support regulations over a decade ago.
Therefore, we are proposing to revise section 13.3 to modify the
alternative relative accuracy criterion such that: (1) It would apply
only at mercury concentrations less than 2.5 [micro]g/scm and (2) the
difference between the average reference method and CEMS values added
to the confidence coefficient would now be 0.5 [micro]g/scm. This
revised criterion is consistent with revisions that we made to the
mercury monitoring requirements in 40 CFR 63, subpart UUUUU (81 FR
20172, April 6, 2016).
Q. Performance Specification 16 of Appendix B of Part 60
In Performance Specification 16, several corrections and
modifications would be made to clarify the intent of the requirements.
In section 1.1, we would correct the language to make it clear that if
a PEMS (predictive emission monitoring system) contains a diluent
component, then the diluent component must be tested as well. Also, in
section 1.1, the language referring to PS-17 would be removed since PS-
17 was never promulgated. In sections 3.11 and 3.12, language would be
added to define commonly used acronyms, and in section 3.12, the
language would be corrected to indicate that the relative accuracy test
audit (RATA) is to be conducted as specified in section 8.2. In section
9.1, the QA/QC Summary chart would be corrected to reflect the language
found in section 2.2, which indicates that the relative accuracy audit
(RAA) is required on all PEMS and not just those classified as
compliance PEMS. The QA/QC Summary Chart is also modified to align the
criteria for a RAA with that found in section 13.5. In section 9.4, the
language stating a RATA is to be conducted at the normal operating
level would be corrected to indicate the RATA is to be conducted as
specified in section 8.2 and to remove the statement that the
statistical tests in section 8.3 are not required for the yearly RATA.
In section 12.3.2, the alternative criteria language would be removed
because it does not apply to F-factor determinations. In sections 13.1
and 13.5, the language would be modified to add the corresponding
alternative criteria in units of lb/mmBtu.
R. Procedure 1 of Appendix F of Part 60
In Procedure 1, in section 4.1, a sentence would be added to
clarify that during a calibration, the reference gas is to be
introduced into the sampling system prior to any sample conditioning or
filtration equipment and must pass through as much of the probe as is
practical. Section 5.2.3 (2) would be modified to refine the
alternative cylinder gas audit (CGA) criteria in response to the use of
analyzers with lower span values. In section 6.2, in order to provide
clarity and clear up any confusion, we would remove the language
referring to the relevant performance specification and insert the
language referring to the use of Equation 1-1.
S. Procedure 5 of Appendix F of Part 60
Regulated entities have pointed out that we did not include
criteria for the system integrity check required in Procedure 5. In
section 2.5, we would clarify that ongoing daily calibration of the Hg
CEMS must be conducted using elemental mercury reference gas. This is
consistent with revisions that we made to the Hg monitoring
requirements in 40 CFR 63, subpart UUUUU (81 FR 20172, April 6, 2016).
We would revise the title of section 4.0 and add section 4.4 to explain
more explicitly the procedure for conducting the system integrity check
as well as to provide the criteria for passing the check. In section
5.1.3, to add clarity we would insert language referring to Equation 1-
1 of Procedure 1 for calculating relative accuracy.
T. General Provisions (Subpart A) of Part 63
In the General Provisions of part 63, Sec. 63.14 would be revised
to: (1) Add ASTM D6784-16 to redesignated paragraph (i) and (2) add
``Standard Methods for the Examination of Water and Wastewater'' Method
5210B to new paragraph (d).
U. National Emission Standards for Hazardous Air Pollutants From the
Pulp and Paper Industry (Subpart S) of Part 63
In subpart S, the existing reference in 40 CFR 63.457(c)(4) to
Method 405.1 of part 136 of chapter 40 for the measurement of
biochemical oxygen demand (BOD) is no longer valid, as Method 405.1 was
withdrawn in 2007. It was replaced with Biochemical Oxygen Demand
Standard Methods 5210 B (72 FR 11199, March 12, 2007), which has been
previously approved in test plans for measuring BOD to demonstrate
compliance with the requirements of subpart S. In Sec. 63.457(c)(4),
Method 405.1 would be updated to reference Method 5210B. This method
would also be incorporated by reference in 40 CFR 63.14.
V. Standards of Performance for Hazardous Air Pollutants From Hazardous
Waste Combustors (Subpart EEE) of Part 63
In the appendix to subpart EEE, we would remove the erroneous
language regarding an Interference Response Test in the introductory
paragraph of section 5 and section 5.3 in its entirety.
W. National Emission Standards for Hazardous Air Pollutants: Paper and
Other Web Coating (Subpart JJJJ) of Part 63
In 2009, revisions were made to Sec. 63.3360(e)(1)(viii) to
clarify that the
[[Page 24493]]
results of Method 25 or Method 25A were being used to determine ``total
organic volatile matter'' (85 FR 41276). At the time, the use of the
terminology ``total gaseous non-methane organic volatile organic
matter'' in Sec. 63.3360(e)(1)(vi) was overlooked. We are proposing to
revise Sec. 63.3360(e)(1)(vi) by removing the term ``non-methane'' to
be consistent with Sec. 63.3360(e)(1)(viii).
X. National Emission Standards for Hazardous Air Pollutants for
Stationary Reciprocating Internal Combustion Engines (Subpart ZZZZ) of
Part 63
We have received multiple inquiries regarding the requirements in
Table 4 of Subpart ZZZZ to measure the exhaust gas moisture when
measuring the concentration of carbon monoxide (CO), formaldehyde, or
THC to demonstrate compliance with the rule. It was first pointed out
that it is not always necessary to measure that exhaust gas moisture
when measuring CO. We would add language to all three sections of Table
4 stating that that the moisture measurement is only necessary when
needed to correct the CO, formaldehyde, THC and/or O2
measurements to a dry basis.
Y. National Emission Standards for Hazardous Air Pollutants: Engine
Test Cells/Stands Residual Risk and Technology Review (Subpart PPPPP)
of Part 63
In subpart PPPPP, the existing erroneous statement in Sec.
63.9306(d)(2)(iv) would be corrected to read, ``Using a pressure sensor
with measurement sensitivity of 0.002 inches water, check gauge
calibration quarterly and transducer calibration monthly.'' Also, in
subpart PPPPP, the existing erroneous statement in Sec. 63.9322(a)(1)
would be corrected to read, ``The capture system meets the criteria in
Method 204 of appendix M to 40 CFR part 51 for a permanent total
enclosure (PE) and directs all the exhaust gases from the enclosure to
an add-on control device.''
Z. National Emission Standards for Hazardous Air Pollutants: Coal- and
Oil-Fired Electric Utility Steam Generating Units (Subpart UUUUU) of
Part 63
We are proposing to revise the references in sections 4.1.1.5 and
4.1.1.5.1 in subpart UUUUU, appendix A to ASTM Method D6784, Standard
Test Method for Elemental, Oxidized, Particle-Bound and Total Mercury
in Flue Gas Generated from Coal-Fired Stationary Sources (Ontario Hydro
Method), to update them from the 2002 version to the latest version,
which was authorized in 2016. In table 5, we are proposing to add ASTM
Method D6784-16 as a mercury testing option as it was inadvertently
left out previously.
AA. Method 315 of Appendix A of Part 63
Section 16.2 is mislabeled as section 6.2 and would be corrected.
BB. Method 323 of Appendix A of Part 63
In Method 323, sections 10.1 and 10.3 would be revised to require
best laboratory practices. The nomenclature in section 12.1 would be
revised to include ``b,'' which is the intercept of the calibration
curve at zero concentration and revise Kc; these additions
are necessary because equation 323-5 in section 12.6 would be revised
to reflect changes in calibration procedures for calculating the mass
of formaldehyde.
VI. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at https://www2.epa.gov/laws-regulations/laws-and-executive-orders.
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review
This action is not a significant regulatory action and was,
therefore, not submitted to the Office of Management and Budget (OMB)
for review.
B. Paperwork Reduction Act (PRA)
This action does not impose an information collection burden under
the PRA. The amendments being proposed in this action to the test
methods, performance specifications, and testing regulations only make
corrections and minor updates to existing testing methodology. In
addition, the proposed amendments clarify performance testing
requirements.
C. Regulatory Flexibility Act (RFA)
I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA. This
action will not impose any requirements on small entities. This
proposed rule will not impose emission measurement requirements beyond
those specified in the current regulations, nor does it change any
emission standard.
D. Unfunded Mandates Reform Act (UMRA)
This action does not contain any unfunded mandate as described in
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect
small governments. The action imposes no enforceable duty on any state,
local or tribal governments or the private sector.
E. Executive Order 13132: Federalism
This action does not have federalism implications. It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications, as specified in
Executive Order 13175. This action would correct and update existing
testing regulations. Thus, Executive Order 13175 does not apply to this
action.
G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
The EPA interprets Executive Order 13045 as applying only to those
regulatory actions that concern environmental health or safety risks
that the EPA has reason to believe may disproportionately affect
children, per the definition of ``covered regulatory action'' in
section 2-202 of the Executive Order. This action is not subject to
Executive Order 13045 because it does not concern an environmental
health risk or safety risk.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution or Use
This action is not subject to Executive Order 13211 because it is
not a significant regulatory action under Executive Order 12866.
I. National Technology Transfer and Advancement Act and 1 CFR Part 51
This action involves technical standards. The EPA proposes to use
ASTM D6216-20 for continuous opacity monitors in Performance
Specification 1. The ASTM D6216-20 standard covers the procedure for
certifying continuous opacity monitors and includes design and
performance specifications, test procedures, and QA requirements to
ensure that continuous opacity monitors meet minimum design and
calibration requirements, necessary in part, for accurate opacity
monitoring measurements in regulatory environmental opacity monitoring
applications subject to 10 percent or
[[Page 24494]]
higher opacity standards. The EPA also proposes to update the version
of ASTM D6784, a test method for elemental, oxidized, particle-bound,
and total mercury in emissions from stationary sources, from the 2002
to 2016 version in the references contained in 40 CFR part 60, appendix
B, Performance Specification 12A for continuous monitoring of mercury
emissions. Likewise, EPA proposes to update the version of ASTM D6784
referenced in table 5 and appendix A of Subpart UUUUU in 40 CFR part
63, for mercury emissions measurement and monitoring. The ASTM D6216-20
and D6784-16 standards were developed and adopted by the American
Society for Testing and Materials. The standards may be obtained from
http://www.astm.org or from the ASTM at 100 Barr Harbor Drive, P.O. Box
C700, West Conshohocken, PA 19428-2959.
The EPA also proposes to use the APHA Method 5210 Biochemical
Oxygen Demand (BOD) from ``Standard Methods for the Examination of
Water and Wastewater.'' This standard is acceptable as an alternative
to Method 405.1 and is available from APHA at www.standardmethods.org
or by telephone at (844) 232-3707.
Additionally, the EPA proposes language intended to correct a
portion of the ASTM E2515-11 test method. The stipulations would modify
the post-test leak check procedures as well as add procedures for
performing leak checks during a sampling run. The stipulations to ASTM
E2515-11 are necessary as we have learned that the quality assurance/
quality control (QA/QC) requirements for leak tests required by ASTM
E2515-11, section 9.6.5.1 are not sufficient to provide assurance of
the sampling system integrity. Additionally, the language of ASTM
E2515-11, section 9.6.5.1 currently allows for averaging the PM results
from a non-leaking sampling system with those from a leaking sampling
system which effectively reduces reported PM emissions by as much as
half, rendering the test method inappropriate for compliance
determination.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
The EPA believes that this action is not subject to Executive Order
12898 (59 FR 7629, February 16, 1994) because it does not establish an
environmental health or safety standard. This action would correct and
update existing testing regulations.

(c) For affected wood heaters subject to the 2015 and 2020
particulate matter emission standards specified in Sec. 60.532(a), (b)
and (c), particulate
[[Page 24495]]
matter emission concentrations must be measured with ASTM E2515-11
(IBR, see Sec. 60.17) with the following exceptions: Eliminate section
9.6.5.1 of ASTM E2515-11 and perform the post-test leak checks as
described in paragraph (c)(1) of this section. Additionally, if a
component change of either sampling train is needed during sampling,
then perform the leak check specified in paragraph (c)(2) of this
section. Four-inch filters and Teflon membrane filters or Teflon-coated
glass fiber filters may be used in ASTM E2515-11.
(1) Post-Test Leak Check: A leak check of each sampling train is
mandatory at the conclusion of each sampling run before sample
recovery. The leak check must be performed in accordance with the
procedures of ASTM E2515-11, section 9.6.4.1 (IBR, see Sec. 60.17),
except that it must be conducted at a vacuum equal to or greater than
the maximum value reached during the sampling run. If the leakage rate
is found to be no greater than 0.0003 m\3\/min (0.01 cfm) or 4% of the
average sampling rate (whichever is less), the leak check results are
acceptable. If a higher leakage rate is obtained, the sampling run is
invalid.
(2) Leak Checks During Sample Run: If, during a sampling run, a
component (e.g., filter assembly) change becomes necessary, a leak
check must be conducted immediately before the change is made. The leak
check must be done according to the procedure outlined in ASTM E2515-
11, section 9.6.4.1 (IBR, see Sec. 60.17), except that it must be done
at a vacuum equal to or greater than the maximum value recorded up to
that point in the sampling run. If the leakage rate is found to be no
greater than 0.0003 m\3\/min (0.01 cfm) or 4% of the average sampling
rate (whichever is less), the leak check results are acceptable. If a
higher leakage rate is obtained, the sampling run is invalid.
Note 1 to paragraph (c)(2): Immediately after component changes,
leak checks are optional but highly recommended. If such leak checks
are done, the procedure in paragraph (c)(1) of this section should
be used.
(d) For all tests conducted using ASTM E2515-11 (IBR, see Sec.
60.17), with the exceptions described in Sec. paragraphs (c)(1) and
(2) of this section, and pursuant to this section, the manufacturer and
approved test laboratory must also measure the first hour of
particulate matter emissions for each test run by sampling with a
third, identical and independent sampling train operated concurrently
for the first hour of PM paired train compliance testing according to
paragraph (c) of this section. The manufacturer and approved test
laboratory must report the test results from this third train
separately as the first hour emissions.

(f) For affected wood heaters subject to the particulate matter
emission standards, particulate matter emission concentrations must be
measured with ASTM E2515-11 (IBR, see Sec. 60.17) with the following
exceptions, eliminate section 9.6.5.1 of ASTM E2515-11 and perform the
post-test leak checks as described in paragraph (f)(1) of this section.
Additionally, if a component change of either sampling train is needed
during sampling, then perform the leak check specified in paragraph
(f)(2 of this section). Four-inch filters and Teflon membrane filters
or Teflon-coated glass fiber filters may be used in ASTM E2515-11. For
all tests conducted using ASTM 2515-11, with the exceptions described
in paragraphs (f)(1) and (2) of this section, the manufacturer and
approved test laboratory must also measure the first hour of
particulate matter emissions for each test run by sampling with a
third, identical and independent sampling train operated concurrently
with the first hour of PM paired train compliance testing. The
manufacturer and approved test laboratory must report the test results
for this third train separately as the first hour emissions.
(1) Post-Test Leak Check: A leak check of each sampling train is
mandatory at the conclusion of each sampling run before sample
recovery. The leak check must be performed in accordance with the
procedures of ASTM E2515-11, section 9.6.4.1 (IBR, see Sec. 60.17),

greater than 0.0003 m\3\/min (0.01 cfm) or 4% of the average sampling
rate (whichever is less), the leak check results are acceptable. If a
higher leakage rate is obtained, the sampling run is invalid.
Note 1 to paragraph (f)(2): Immediately after component changes,
leak checks are optional but highly recommended. If such leak checks
are done, the procedure in paragraph (f)(1) of this section should
be used.

Method 1--Sample and Velocity Traverses For Stationary Sources
* * * * *
11.5 Alternative Measurement Site Selection Procedure. The
alternative site selection procedure may be used to determine the
rotation angles in lieu of the procedure outlined in section 11.4.
11.5.1 This alternative procedure applies to sources where
measurement locations are less than 2 equivalent or duct diameters
downstream or less than one-half duct diameter upstream from a flow
disturbance. The alternative should be limited to ducts larger than
24 inches in diameter where blockage and wall effects are minimal. A
directional flow-sensing probe is used to measure pitch and yaw
angles of the gas flow at 40 or more traverse points; the resultant
angle is calculated and compared with acceptable criteria for mean
and standard deviation.
Note: Both the pitch and yaw angles are measured from a line
passing through the traverse point and parallel to the stack axis.
The pitch angle is the angle of the gas flow component in the plane
that INCLUDES the traverse line and is parallel to the stack axis.
The yaw angle is the angle of the gas flow component in the plane
PERPENDICULAR to the traverse line at the traverse point and is
measured from the line passing through the traverse point and
parallel to the stack axis.
11.5.2 Traverse Points. Use a minimum of 40 traverse points for
circular ducts and 42 points for rectangular ducts for the gas flow
angle determinations. Follow the procedure outlined in section 11.3
and Table 1-1 or 1-2 of this method for the location and layout of
the traverse points. If the alternative measurement location is
determined to be acceptable according to the criteria in this
alternative procedure, use the same minimum of 40 traverse points
for circular ducts and 42 points for rectangular ducts that were
used in the alternative measurement procedure for future sampling
and velocity measurements.

Performance Specification 1--Specifications and Test Procedures for
Continuous Opacity Monitoring Systems in Stationary Sources
* * * * *
2.1 ASTM D6216 (IBR, see Sec. 60.17) is the reference for
design specifications, manufacturer's performance specifications,
and test procedures. The opacity monitor manufacturer must
periodically select and test an opacity monitor, that is
representative of a group of monitors produced during a specified
period or lot, for conformance with the design specifications in
ASTM D6216. The opacity monitor manufacturer must test each opacity
monitor for conformance with the manufacturer's performance
specifications in ASTM D6216. Note: If the initial certification of
the opacity monitor occurred before [the effective date of the final
rule] using ASTM D6216-98, D6216-03, D6216-07, or D6216-12, it is
not necessary to recertify using ASTM D6216-20.
* * * * *
3.1 All definitions and discussions from section 3 of ASTM D6216
are applicable to PS-1.
* * * * *
6.1 Continuous Opacity Monitoring System. You, as owner or
operator, are responsible for purchasing an opacity monitor that
meets the specifications of ASTM D6216, including a suitable data
recorder or automated data acquisition handling system. Example data
recorders include an analog strip chart recorder or more
appropriately an electronic data acquisition and reporting system
with an input signal range compatible with the analyzer output.
* * * * *
8.1 * * *
(1) You must purchase an opacity monitor that complies with ASTM
D6216 and obtain a certificate of conformance from the opacity
monitor manufacturer.
(2) * * *
(iii) Alternative Locations and Light Beam Paths. You may select
locations and light beam paths, other than those cited above, if you
demonstrate, to the satisfaction of the Administrator or delegated
agent, that the average opacity measured at the alternative location
or path is equivalent to the opacity as measured at a location
meeting the criteria of sections 8.1(2)(i) and 8.1(2)(ii). The
opacity at the alternative location is considered equivalent if
{1{time} the average opacity value measured at the alternative
location is within 10 percent of the average opacity
value measured at the location meeting the installation criteria,
and {2{time} the difference between any two average opacity values
is less than 2 percent opacity (absolute). You use the following
procedure to conduct this demonstration: Simultaneously measure the
opacities at the two locations or paths for a minimum period of time
(e.g., 180-minutes) covering the range of normal operating
conditions and compare the results. You may use alternative
procedures for determining acceptable locations if those procedures
are approved by the Administrator.
(3) * * *
(ii) Calibration Error Check. Conduct a three-point calibration
error test using three calibration attenuators that produce outlet
pathlength corrected, single-pass opacity values shown in ASTM
D6216, section 7.5. If your applicable limit is less than 10 percent
opacity, use attenuators as described in ASTM D6216, section 7.5 for
applicable standards of 10 to 19 percent opacity. Confirm the
external audit device produces the proper zero value on the COMS
data recorder. Separately, insert each calibration attenuators (low,
mid, and high-level) into the external audit device. While inserting
each attenuator, {1{time} ensure that the entire light beam passes
through the attenuator, {2{time} minimize interference from
reflected light, and {3{time} leave the attenuator in place for at
least two times the shortest recording interval on the COMS data
recorder. Make a total of five nonconsecutive readings for each
attenuator. At the end of the test, correlate each attenuator
insertion to the corresponding value from the data recorder.
Subtract the single-pass calibration attenuator values corrected to
the stack exit conditions from the COMS responses. Calculate the
arithmetic mean difference, standard deviation, and confidence
coefficient of the five measurements value using equations 1-3, 1-4,
and 1-5. Calculate the calibration error as the sum of the absolute
value of the mean difference and the 95 percent confidence
coefficient for each of the three test attenuators using equation 1-
6. Report the calibration error test results for each of the three
attenuators.
* * * * *
8.2 * * *
(1) Conduct the verification procedures for design
specifications in section 6 of ASTM D6216.
(2) Conduct the verification procedures for performance
specifications in section 7 of ASTM D6216.
(3) Provide to the owner or operator, a report of the opacity
monitor's conformance to the design and performance specifications
required in sections 6 and 7 of ASTM D6216 in accordance with the
reporting requirements of section 9 in ASTM D6216.
9.0 What quality control measures are required by PS-1?
Opacity monitor manufacturers must initiate a quality program
following the requirements of ASTM D6216, section 8. The quality
program must include:
(1) A quality system and
(2) A corrective action program.
* * * * *
12.1 Desired Attenuator Values. Calculate the desired attenuator
value corrected to the emission outlet pathlength as follows:
[GRAPHIC] [TIFF OMITTED] TP26AP22.084
Where:
OP1 = Nominal opacity value of required low-, mid-, or
high-range calibration attenuators.
OP2 = Desired attenuator opacity value from ASTM D6216,
section 7.5 at the opacity limit required by the applicable subpart.
L1 = Monitoring pathlength.
L2 = Emission outlet pathlength.
* * * * *
13.1 Design Specifications. The opacity monitoring equipment
must comply with the design specifications of ASTM D6216.
13.2 Manufacturer's Performance Specifications. The opacity
monitor must comply with the manufacturer's performance
specifications of ASTM D6216.

8.3.3 Conduct the CD test at the two points specified in section
6.1.2. Introduce to the CEMS the reference gases, gas cells, or
optical filters (these need not be certified). When using reference
gases, introduce the reference gas prior to any sample conditioning
or filtration equipment and ensure that it passes through all
filters,
[[Page 24500]]
scrubbers, conditioners, and other monitor components used during
normal sampling. The reference gas should pass through as much of
the sampling probe as practical. Record the CEMS response and
subtract this value from the reference value (see example data sheet
in Figure 2-1).

12.5 Relative Accuracy. Calculate the RA, expressed as a
percentage, of a set of data as follows:
[GRAPHIC] [TIFF OMITTED] TP26AP22.085
Where:
[verbar]d[verbar] = Absolute value of the mean differences (from
Equation 2-3).
[verbar]CC[verbar] = Absolute value of the confidence coefficient
(from Equation 2-3).
RM = Average RM value. In cases where the average emissions for the
test are less than 50 percent of the applicable emission standard,
substitute the applicable emission standard value in the denominator
of Eq. 2-6 in place of the average RM value. In all other cases, use
RM.

Applicability
This specification is to be used for evaluating the
acceptability of carbon monoxide (CO) and oxygen (O2)
continuous emission monitoring systems (CEMS) at the time of or soon
after installation and whenever specified in the regulations. The
CEMS may include, for certain stationary sources, (a) flow
monitoring equipment to allow measurement of the dry volume of stack
effluent sampled, and (b) an automatic sampling system.
This specification is not designed to evaluate the installed
CEMS' performance over an extended period of time, nor does it
identify specific calibration techniques and auxiliary procedures to
assess the CEMS' performance. The source owner or operator, however,
is responsible to properly calibrate, maintain, and operate the
CEMS. To evaluate the CEMS' performance, the Administrator may
require, under section 114 of the Act, the operator to conduct CEMS
performance evaluations at times other than the initial test.
The definitions, installation and measurement location
specifications, test procedures, data reduction procedures,
reporting requirements, and bibliography are the same as in PS 3
(for O2) and PS 4A (for CO) except as otherwise noted
below.
Summary of Performance Specification
Installation and measurement location specifications,
performance specifications, test procedures, and data reduction
procedures are included in this specification. Reference method
tests, calibration error tests, calibration drift tests, and
interferant tests are conducted to determine conformance of the CEMS
with the specification.
Definitions
The definitions are the same as in section 3.0 of PS2 with the
following definitions added:
Continuous Emission Monitoring System (CEMS). This definition is
the same as PS 2 section 3.0 with the following addition. A
continuous monitor is one in which the sample to be analyzed passes
the measurement section of the analyzer without interruption.
Response Time (RT). The time interval between the start of a
step change in the system input and when the pollutant analyzer
output reaches 95 percent of the final value.
Calibration Error (CE). The difference between the concentration
indicated by the CEMS and the known concentration generated by a
calibration source when the entire CEMS, including the sampling
interface is challenged. A CE test procedure is performed to
document the accuracy and linearity of the CEMS over the entire
measurement range.
Interferences [Reserved]
Safety
This performance specification may involve hazardous materials,
operations, and equipment. This performance specification may not
address all of the safety problems associated with its use. It is
the responsibility of the user to establish appropriate safety and
health practices and determine the applicable regulatory limitations
prior to performing this performance specification. The CEMS user's
manual should be consulted for specific precautions to be taken with
regard to the analytical procedures.
Equipment and Supplies
Same as section 6.0 of PS 2, except for the following:
Data Recorder Scale. For O2, same as specified in PS
3, except that the span must be 25 percent. The span of the
O2 may be higher if the O2 concentration at
the sampling point can be greater than 25 percent. For CO, same as
specified in PS 4A, except that the low-range span must be 200 ppm
and the high range span must be 3000 ppm. In addition, the scale for
both CEMS must record all readings within a measurement range with a
resolution of 0.5 percent.
Reagents and Standards
Sample Collection, Preservation, Storage, and Transport
Installation and Measurement Location Specifications
The CEMS Installation. This specification is the same as PS 2
section 8.1.1 with the following additions. Both the CO and
O2 monitors should be installed at the same general
location. If this is not possible, they may be installed at
different locations if the effluent gases at both sample locations
are not stratified and there is no in-leakage of air between
sampling locations.
Measurement Location. Same as PS 2 section 8.1.2.
Point CEMS. The measurement point should be within or centrally
located over the centroidal area of the stack or duct cross section.
Path CEMS. The effective measurement path should: (1) Have at
least 70 percent of the path within the inner 50 percent of the
stack or duct cross sectional area, or (2) be centrally located over
any part of the centroidal area.
Reference Method (RM) Measurement Location and Traverse Points
This specification is the same as PS 2 section 8.1.3 with the
following additions. When pollutant concentration changes are due
solely to diluent leakage and CO and O2 are
simultaneously measured at the same location, one half diameter may
be used in place of two equivalent diameters.
Pretest Preparation. Install the CEMS, prepare the RM test site
according to the specifications in section 8.1, and prepare the CEMS
for operation according to the manufacturer's written instructions.
Stratification Test Procedure. Stratification is defined as the
difference in excess of 10 percent between the average concentration
in the duct or stack and the concentration at any point more than
1.0 meter from the duct or stack wall. To determine whether effluent
stratification exists, a dual probe system should be used to
determine the average effluent concentration while measurements at
each traverse point are being made. One probe, located at the stack
or duct centroid, is used as a stationary reference point to
indicate change in the effluent concentration over time. The second
probe is used for sampling at the traverse points specified in
Method 1 (40 CFR part 60 appendix A). The monitoring system samples
sequentially at the reference and traverse points throughout the
testing period for five minutes at each point.
Calibration Drift Test Procedure. Same as section 8.3 in PS 2.
[[Page 24501]]
Note: The CE and RT tests must be conducted during the CD test
period.
Calibration Error Test Procedure. Challenge each monitor (both
low and high range CO and O2) with zero gas and EPA
Protocol 1 cylinder gases at three measurement points within the
ranges specified in Table 4B-1 (in section 18.0).
Operate each monitor in its normal sampling mode as nearly as
possible. The calibration gas must be injected into the sample
system as close to the sampling probe outlet as practical and should
pass through all CEMS components used during normal sampling.
Challenge the CEMS three non-consecutive times at each measurement
point and record the responses. The duration of each gas injection
should be sufficient to ensure that the CEMS surfaces are
conditioned.
Response Time Test Procedure. Same as section 8.3 in PS 4A and
must be carried out for both the CO and O2 monitors.
Relative Accuracy Test Procedure. Sampling Strategy for
Reference Method (RM) Tests, Number of RM Tests, and Correlation of
RM and CEMS Data are the same as PS 2, sections 8.4.3, 8.4.4, and
8.4.5, respectively.
Quality Control [Reserved]
Calibration and Standardization [Reserved]
Analytical Procedure
Sample collection and analysis are concurrent for this
Performance Specification (see section 8.0). Refer to the RM for
specific analytical procedures.
Calculation and Data Analysis
Summarize the results on a data sheet as shown in Figure 4B-1
(in section 18.0).
Calibration Error (CE) is the average the differences between
the instrument response and the certified cylinder gas value for
each gas. Calculate the CE results for the CO monitor according to:
[GRAPHIC] [TIFF OMITTED] TP26AP22.086
Where:
d = mean difference between the CEMS response and the known
reference concentration, and
FS = span value.
The CE for the O2 monitor is the average percent
O2 difference between the O2 monitor and the
certified cylinder gas value for each gas.
Method Performance
Calibration Drift Performance Specification. For O2,
same as specified in PS 3. For CO, the same as specified in PS 4A
except that the CEMS calibration must not drift from the reference
value of the calibration standard by more than 3 percent of the span
value on either the high or low range.
Calibration Error (CE) Performance Specification. The mean
difference between the CEMS and reference values at all three test
points (see Table 4B-1) must be no greater than 5 percent of span
value for CO monitors and 0.5 percent for O2 monitors.
Response Time Performance Specification. The response time for
the CO or O2 monitor must not exceed 240 seconds.
Relative Accuracy (RA) Performance Specification. For
O2, same as specified in PS 3. For CO, the same as
specified in PS 4A.
Pollution Prevention [Reserved]
Waste Management [Reserved]
Alternative Procedure
Alternative RA Procedure. Under some operating conditions, it
may not be possible to obtain meaningful results using the RA test
procedure. This includes conditions where consistent, very low CO
emission or low CO emissions interrupted periodically by short
duration, high level spikes are observed. It may be appropriate in
these circumstances to waive the RA test and substitute the
following procedure.
Conduct a complete CEMS status check following the
manufacturer's written instructions. The check should include
operation of the light source, signal receiver, timing mechanism
functions, data acquisition and data reduction functions, data
recorders, mechanically operated functions, sample filters, sample
line heaters, moisture traps, and other related functions of the
CEMS, as applicable. All parts of the CEMS must be functioning
properly before the RA requirement can be waived. The instrument
must also successfully pass the CE and CD specifications.
Substitution of the alternate procedure requires approval of the
Regional Administrator.

13.2 CERMS Relative Accuracy. Calculate the CERMS Relative
Accuracy (RA) expressed as a percentage using Eq. 2-6 of section 12

standard. If the average emissions for the test are less than 50
percent of the applicable emission standard, substitute the
applicable emission standard value in the denominator of Eq. 2-6 in

8.4.2 Reference Methods (RM). Unless otherwise specified in an
applicable subpart of the regulations, use Method 29, Method 30A, or
Method 30B in appendix A-8 to this part or ASTM D6784 (IBR, see
Sec. 60.17) as the RM for Hg concentration. For Method 29 and ASTM
D6784 only, the filterable portion of the sample need not be
included when making comparisons to the CEMS results. When Method
29, Method 30B, or ASTM D6784-16 is used, conduct the RM test runs
with paired or duplicate sampling systems and use the average of the
vapor phase Hg concentrations measured by the two trains. When
Method 30A is used, paired sampling systems are not required. If the
RM and CEMS measure on a different moisture basis, data derived with
Method 4 in appendix A-3 to this part must also be obtained during
the RA test.
* * * * *
8.4.4 Number and Length of RM Test Runs. Conduct a minimum of
nine RM test runs. When Method 29, Method 30B, or ASTM D6784 is
used, only test runs for which the paired RM trains meet the
relative deviation criteria (RD) of this PS must be used in the RA
calculations. In addition, for Method 29 and ASTM D6784, use a
minimum sample time of 2 hours and for Methods 30A and 30B use a
minimum sample time of 30 minutes.
* * * * *
8.4.5 Correlation of RM and CEMS Data. Correlate the CEMS and
the RM test data as to the time and duration by first determining
from the CEMS final output (the one used for reporting) the
integrated average pollutant concentration for each RM test period.
Consider system response time, if important, and confirm that the
results are on a consistent moisture basis with the RM test. Then,
compare each integrated CEMS value against the corresponding RM
value. When Method 29, Method 30B, or ASTM D6784 is used, compare
each CEMS value against the corresponding average of the paired RM
values.
* * * * *
8.4.6.1 When Method 29, Method 30B, or ASTM D6784 is used,
outliers are identified through the determination of relative
deviation (RD) of the paired RM tests. Data that do not meet the RD
criteria must be flagged as a data quality problem and may not be
used in the calculation of RA. The primary reason for performing
paired RM sampling is to ensure the quality of the RM data. The
percent RD of paired data is the parameter used to quantify data
quality. Determine RD for paired data points as follows: Where: Ca
and Cb are the Hg concentration values determined from the paired
samples.
* * * * *
13.3 Relative Accuracy (RA). The RA of the CEMS must be no
greater than 20 percent of the mean value of the RM test data in
terms of units of [micro]g/scm. Alternatively, if the mean RM is
less than 2.5 [micro]g/scm, the results are acceptable if the
absolute value of the difference between the mean RM and CEMS values
added to the absolute value of the confidence coefficient from
Equation 12A-7 does not exceed 0.5 [micro]g/scm.

1.1 Does this performance specification apply to me? If you, the
source owner or operator, intend to use (with any necessary
approvals) a predictive emission monitoring system (PEMS) to show
compliance with
[[Page 24503]]
your emission limitation under 40 CFR parts 60, 61, or 63, you must
use the procedures in this performance specification (PS) to
determine whether your PEMS is acceptable for use in demonstrating
compliance with applicable requirements. Use these procedures to
certify your PEMS after initial installation and periodically
thereafter to ensure the PEMS is operating properly. If your PEMS
contains a diluent (O2 or CO2) measuring
component, the diluent component must be tested as well. These
specifications apply to PEMS that are installed under 40 CFR parts
60, 61, and 63 after the effective date of this performance
specification.

used in place of the portable analyzer for the RAA.
3.12 Relative Accuracy Test Audit (RATA) means a RA test that is
performed at least once every four calendar quarters after the
initial certification test. The RATA shall be conducted as described

9.4 Yearly Relative Accuracy Test Audit. Perform a minimum 9-run
RATA as specified by section 8.2 on a yearly basis in the quarter
that the RAA is not performed.
* * * * *
12.3.2 F-test. Conduct an F-test for each of the three RA data
sets collected at different test levels. Calculate the variances of
the PEMS and the RM using Equation 16-6.
[GRAPHIC] [TIFF OMITTED] TP26AP22.087
Determine if the variance of the PEMS data is significantly
different from that of the RM data at each level by calculating the
F-value using Equation 16-7.
[GRAPHIC] [TIFF OMITTED] TP26AP22.088
Compare the calculated F-value with the critical value of F at
the 95 percent confidence level with n-1 degrees of freedom. The
critical value is obtained from Table 16-2 or a similar table for F-
distribution. If the calculated F-value is greater than the critical
value at any level, your proposed PEMS is unacceptable.
* * * * *
13.1 PEMS Relative Accuracy. The RA, calculated in units of the
emission standard, must not exceed 10 percent if the PEMS
measurements are greater than 100 ppm or 0.2 lbs/mm Btu. The RA must
not exceed 20 percent if the PEMS measurements are between 100 ppm
(or 0.2 lb/mm Btu) and 10 ppm (or 0.02 lb/mm Btu). For measurements
below 10 ppm (or 0.02 lb/mm Btu), the absolute mean difference
between the PEMS measurements and the RM measurements must not
exceed 2 ppm (or 0.01 lb/mm Btu). For diluent only PEMS, an
alternative criterion of 1 percent absolute difference
between the PEMS and RM may be used if less stringent.
* * * * *
13.5 Relative Accuracy Audits (RAA). The average of the three
portable analyzer or RM determinations must not differ from the
simultaneous PEMS average value by more than 10 percent of the
analyzer or RM for concentrations greater than 100 ppm (or 0.2 lb/mm
Btu) or 20 percent for concentrations between 100 ppm (or 0.2 lb/mm
Btu) and 20 ppm (or 0.04 lb/mm Btu), or the test is failed. For
measurements at 20 ppm (or 0.04 lb/mm Btu) or less, this difference
must not exceed 2 ppm (or 0.01 lb/mm Btu) for a pollutant PEMS. For
diluent PEMS, the difference must not exceed 1 percent.

4.1 CD Requirement. As described in 40 CFR 60.13(d), source
owners and operators of CEMS must check, record, and quantify the CD
at two concentration values at least once daily (approximately 24
hours) in accordance with the method prescribed by the manufacturer.
When using reference gases, introduce the reference gas prior to any
sample conditioning or filtration equipment and ensure that it
passes through all filters, scrubbers, conditioners, and other
monitor components used during normal sampling. The reference gas
must pass through as much of the sampling probe as practical. The
CEMS calibration must, as minimum, be adjusted whenever the daily
zero (or low-level) CD or the daily high-level CD exceeds two times
the limits of the applicable PS's in appendix B of this regulation.
* * * * *
5.2.3 * * *
(1) * * *
(2) For the CGA, for pollutant monitors, the audit inaccuracy
must be 15 percent of the average audit value as
calculated using Equation 1-1 or the difference between the average
CEMS response and the average audit value must be less than one of
the following:

audit value.
(3) For the RAA, 15 percent of the three-run average
or 7.5 percent of the applicable standard, whichever is
greater.
* * * * *
6.2 RAA Accuracy Calculation. Use Equation 1-1 to calculate the
accuracy for the RAA. The RAA must be calculated in the units of the
applicable emission standard.

Check
* * * * *
4.4 Weekly System Integrity Check. At least once every 7
calendar days, using the procedure described in section 8.3.3 of
Performance Specification 12A in appendix B to this part, source
owners and operators of Hg CEMS must use a single mid- or high-level
oxidized Hg (mercuric chloride, HgCl2) reference gas to
assess transport and measurement of oxidized mercury. The absolute
value of the difference between the Hg CEMS output response and the
reference gas value, as a percentage of span, must not be greater
than 10.0 percent.
* * * * *
5.1.3 Relative Accuracy Audit (RAA). As an alternative to the
QGA, a RAA may be conducted in three of four calendar quarters, but
in no more than three quarters in succession. To conduct a RAA,
follow the RATA test procedures in section 8.5 of PS 12A in appendix
B to this part, except that only three test runs are required.
Calculate the relative accuracy according to Equation 1-1 of
Procedure 1 of this appendix.

quarterly, and a Relative Accuracy Test Audit (RATA) (if applicable,
see sections 5.1 and 5.2) must be conducted yearly. When a
performance test is also required under Sec. 63.1207 to document
compliance with emission standards, the RATA must coincide with the
performance test. The audits must be conducted as follows.
5.1 Relative Accuracy Test Audit (RATA). This requirement
applies to O2 and CO CEMS. The RATA must be conducted at
least yearly. Conduct the RATA as described in the RA test procedure
(or alternate procedures section) described in the applicable
Performance Specifications. In addition, analyze the appropriate
performance audit samples received from the EPA as described in the
applicable sampling methods.
5.2 Absolute Calibration Audit (ACA). The ACA must be conducted
at least quarterly except in a quarter when a RATA (if applicable,
see section 5.1) is conducted instead. Conduct an ACA as described
in the
[[Page 24505]]
calibration error (CE) test procedure described in the applicable
Performance Specifications.
5.3 Excessive Audit Inaccuracy. If the RA from the RATA or the
CE from the ACA exceeds the criteria in the applicable Performance
Specifications, hazardous waste burning must cease immediately.
Hazardous waste burning cannot resume until the owner or operator
takes corrective measures and audit the CEMS with a RATA to document
that the CEMS is operating within the specifications.

29. Amend sections 4.1.1.5 and 4.1.1.5.1 under ``4. Certification and
Recertification Requirements'' in Appendix A to subpart UUUUU of part
63 to read as follows:
Appendix A to Subpart UUUUU--Hg Monitoring Provision
* * * * *
4.1.1.5 Relative Accuracy Test Audit (RATA). Perform the RATA of
the Hg CEMS at normal load. Acceptable Hg reference methods for the
RATA include ASTM D6784 (IBR, see Sec. 63.14) and Methods 29, 30A,
and 30B in appendix A-8 to part 60 of this chapter. When Method 29
or ASTM D6784 is used, paired sampling trains are required, and the
filterable portion of the sample need not be included when making
comparisons to the Hg CEMS results for purposes of a RATA. To
validate a Method 29 or ASTM D6784 test run, calculate the relative
deviation (RD) using Equation A-1 of this section, and assess the
results as follows to validate the run. The RD must not exceed 10
percent, when the average Hg concentration is greater than 1.0
[micro]g/dscm. If the RD specification is met, the results of the
two samples shall be averaged arithmetically.
[GRAPHIC] [TIFF OMITTED] TP26AP22.090
Where:
RD = Relative Deviation between the Hg concentrations of samples
``a'' and ``b'' (percent),
Ca = Hg concentration of Hg sample ``a'' ([micro]g/dscm),
and
Cb = Hg concentration of Hg sample ``b'' ([micro]g/dscm).
4.1.1.5.1 Special Considerations. A minimum of nine valid test
runs must be performed, directly comparing the CEMS measurements to
the reference method. More than nine test runs may be performed. If
this option is chosen, the results from a maximum of three test runs
may be rejected so long as the total number of test results used to
determine the relative accuracy is greater than or equal to nine;
however, all data must be reported including the rejected data. The
minimum time per run is 21 minutes if Method 30A is used. If Method
29, Method 30B, or ASTM D6784 (IBR, see Sec. 63.14) is used, the
time per run must be long enough to collect a sufficient mass of Hg
to analyze. Complete the RATA within 168 unit operating hours,
except when Method 29 or ASTM D6784 is used, in which case; up to
336 operating hours may be taken to finish the test.

orifices may be used as calibration standards in place of the wet
test meter specified in section 10.3 of this method, provided that
they are selected, calibrated, and used as follows:
* * * * *
Method 323--Measurement of Formaldehyde Emissions From Natural Gas-
Fired Stationary Sources--Acetyl Acetone Derivatization Method
* * * * *
10.1 Spectrophotometer Calibration. Prepare a stock solution of
10 [micro]g/mL formaldehyde. Prepare a series of calibration
standards from the stock solution corresponding to 0.0, 0.5, 1.5,
3.5, 5.0, and 7.5 [micro]g/mL formaldehyde. Mix 2.0 ml of each
calibration standard with 2.0 mL of acetyl acetone reagent in screw
cap vials, thoroughly mix the solution, and place the vials in a
water bath (or heating block) at 60 [deg]C for 10 minutes. Remove
the vials and allow to cool to room temperature. Transfer each
solution to a cuvette and measure the absorbance at 412 nm using the
spectrophotometer. Develop a calibration curve (response vs.
concentration) from the analytical results of these standards. The
acceptance criteria for the spectrophotometer calibration is a
correlation coefficient of 0.99 or higher. If this criterion is not
met, the calibration procedures should be repeated.
* * * * *
10.3 Calibration Checks. Calibration checks consisting of
analyzing a mid-range standard separate prepared with each batch of
samples. The calibration check standard must be prepared independent
of the calibration stock solution. The result of the check standard
must be within 10 percent of the theoretical value to be acceptable.
If the acceptance criteria are not met, the standard must be
reanalyzed. If still unacceptable, a new calibration curve must be
prepared using freshly prepared standards.
* * * * *
12.1 Nomenclature.
* * * * *
b = the intercept of the calibration curve at zero concentration
* * * * *
Kc = spectrophotometer calibration factor, slope of the
least square regression line, absorbance/([micro]g/mL) (Note: Most
spreadsheets are capable of calculating a least squares line,
including slope, intercept, and correlation coefficient).
