Revisions to Test Methods, Performance Specifications, and
Testing Regulations for Air Emission Sources

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: This action proposes technical and editorial corrections and
revisions to regulations related to source testing of emissions. This
proposed rule will make corrections and updates to testing provisions
that contain inaccuracies and outdated procedures, and provide
alternatives to existing testing regulations. These revisions will
improve the quality of data and provide testers flexibility to use
recently-approved alternative procedures. Many of these changes were
suggested by testers and other end-users, and they will not impose new
substantive requirements on source owners or operators.

DATES: Comments must be received on or before November 9, 2015.
    Public Hearing. If anyone contacts the Environmental Protection
Agency (EPA) by September 18, 2015 requesting to speak at a public
hearing, a hearing will be held on October 8, 2015.

I. General Information

A. Does this action apply to me?

    The proposed amendments apply to industries that are already
subject to the current provisions of parts 51, 60, 61, and 63. For
example, Performance Specification 4A applies to municipal waste
combustors and hazardous waste incinerators. We did not list all of the
specific affected industries or their North American Industry
Classification System (NAICS) codes herein since there are many
affected sources. 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 should I consider as I prepare my comments for the EPA?

    1. Submitting CBI. Do not submit this information to the EPA
through http://www.regulations.gov or email. Clearly mark any of the
information that you claim to be CBI. For CBI information in a disk or
CD-ROM that you mail to the EPA, mark the outside of the disk or CD-ROM
as CBI and then identify electronically within the disk or CD-ROM the
specific information that is claimed as CBI. In addition to one
complete version of the comment that includes information claimed as
CBI, a copy of the comment that does not contain the information
claimed as CBI must be submitted for inclusion in the public docket.
Information so marked will not be disclosed except in accordance with
procedures set forth in 40 CFR part 2.
    2. Tips for Preparing Your Comments. When submitting comments,
remember to:
     Follow directions--The agency may ask you to respond to
specific questions or organize comments by referencing a Code of
Federal Regulations (CFR) part or section number.
     Explain why you agree or disagree, suggest alternatives,
and substitute language for your requested changes.
     Describe any assumptions and provide any technical
information and/or data that you used.
     If you estimate potential costs or burdens, explain how
you arrived at your estimate in sufficient detail to allow for it to be
reproduced.
     Provide specific examples to illustrate your concerns, and
suggest alternatives.
     Explain your views as clearly as possible, avoiding the
use of profanity or personal threats.
     Make sure to submit your comments by the comment period
deadline identified.

C. Where can I get a copy of this document?

    In addition to being available in the docket, an electronic copy of
this proposed rule will also be available on the Worldwide Web (WWW)
through the Technology Transfer Network (TTN). Following signature, a
copy of this proposed rule will be posted at the following address:
http://www.epa.gov/ttn/emc/. The TTN provides information and
technology exchange in various areas of air pollution control.

II. Background

    The EPA has been cataloging errors and corrections, as well as
revisions that are needed to test methods, performance specifications,
and associated regulations in 40 CFR parts 51, 60, 61, and 63. The most
recent final rule that updated and revised methods was published on
February 27, 2014 (79 FR 11228). Many of the corrections and revisions
herein have been brought to our attention by affected parties and end-
users. The corrections and revisions consist primarily of typographical
errors, technical errors in equations and diagrams, updates to
procedures, and the addition of alternative equipment and methods the
Agency has found acceptable to use.

III. Summary of Proposed Amendments

A. Appendix M to Part 51

    In paragraph (4)(a) of appendix M to part 51, we propose to add
Methods 30A and 30B to the list of methods not requiring the use of
audit samples. Consistent with the criteria used in establishing the
original list of methods for which no audit samples are required (75 FR
55636), Method 30A is an instrumental test method that already has
sufficient calibration and quality assurance requirements. Method 30B
has sufficient performance-based quality assurance measures including
analysis of an independent calibration standard with each set of field
samples.

B. Method 201A of Appendix M to Part 51

    In Method 201A, the constant in equation 9, which is shown as
0.07657, will be corrected to 0.007657.

C. Method 202 of Appendix M to Part 51

    In Method 202, we propose to add section 3.8 to incorporate ASTM
E617-13 by reference. The first sentence in paragraph <IP_ADDRESS> will be
revised by adding ``back half of the filterable PM filter holder.''
Section 9.10 erroneously states ``You must purge the assembled train as
described in sections <IP_ADDRESS> and <IP_ADDRESS>.'' The statement will be
corrected to reference section 8.5.3. Sections 10.3 and 10.4 will be
added to require calibration of the balance used to weigh impingers and
to require a multipoint calibration of the analytical balance. During
the most recent revision of Method 202, sections <IP_ADDRESS>, <IP_ADDRESS>,
<IP_ADDRESS>, <IP_ADDRESS> and figure 7 were inadvertently deleted and will be
re-inserted into the method.

D. Appendix P to Part 51

    In appendix P to part 51, section 3.3 erroneously refers to section
2.1 of Performance Specification 2 of appendix B of part 60. The
citation will be corrected to section 6.1. Section 5.1.3 erroneously
refers to paragraph 4.1.4, which does not exist; the text will be
changed to reflect the correct references to paragraphs 3.1.4 and
3.1.5.

E. General Provisions (Subpart A) Part 60

    In the General Provisions of part 60, Sec.  60.8(f) will be revised
to require the reporting of specific emissions test data in test
reports. These data elements will be required regardless of whether the
report is submitted electronically or in paper format. 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. Section 60.17(g) will be
revised to add ASTM D6911-15 to the list of incorporations by reference
and to re-number the remaining consensus standards that are
incorporated by reference in alpha-numeric order.

F. Standards of Performance for Stationary Spark Ignition Internal
Combustion Engines (Subpart JJJJ) Part 60

    In Table 2 of subpart JJJJ, Methods 18 and 320 and ASTM D 6348-03
will be deleted as test method options for measuring VOC, and only
Method 25A will be allowed.

G. Method 1 of Appendix A-1 to Part 60

    In Method 1, section <IP_ADDRESS>, the word ``istances'' will be
changed to ``distances'' in the second sentence. In addition, there are
two figures labeled Figure 1-2. The second figure will be deleted.

H. Method 2 of Appendix A-1 to Part 60

    In Method 2, instructions are given for conducting S-type pitot
calibrations. Currently, the same equipment is commonly used for both
Methods 2 and 2G (same S-type pitot), but the calibration procedure is
slightly different in each method. Other key pieces that enhance the
quality assurance/quality control (QA/QC) of the calibrations will be
added to Method 2, and the amount of blockage allowed will be reduced
to tighten up calibration accuracy. To address these issues, changes
will be made to sections 6.7, <IP_ADDRESS>, <IP_ADDRESS>, <IP_ADDRESS>, and
<IP_ADDRESS>.3 of Method 2. Section <IP_ADDRESS> inadvertently references
section <IP_ADDRESS>. The reference will be corrected to section 12.4.4.
The side of Figure 2-10 labeled (b) will be deleted, and the label (a)
will be removed from the figure.

I. Method 2G of Appendix A-2 to Part 60

    In Method 2G, instructions are given for conducting S-type pitot
calibrations. Currently the same equipment is commonly used for both
Methods 2 and 2G (same S-type pitot), but the calibration procedure is
slightly different in each method. Other key pieces that enhance the
QA/QC of the calibrations will be added to the method, and the amount
of blockage allowed will be reduced to tighten up calibration accuracy.
Changes will be made to sections 6.11.1, 6.11.2, 10.6.6, and 10.6.8 of
Method 2G to address these issues.

J. Method 3C of Appendix A-2 to Part 60

    In Method 3C, section 6.3 will be revised to add subsections
(6.3.1, 6.3.2, 6.3.3, 6.3.4, and 6.3.5) that clarify the requirements
necessary to check analyzer linearity.

K. Method 4 of Appendix A-3 to Part 60

    In Method 4, section 10.3 (Field Balance) will be added to require
calibration of the balance used to weigh impingers. Section 12.2.5 will
be added, which provides another option for calculating the approximate
moisture content. Section 16.4 will be revised to clarify that a fuel
sample must be taken and analyzed to develop F-factors required by the
alternative. Also, in section 16.4, percent relative humidity is
inadvertently defined as ``calibrated hydrometer acceptable''; the word
``hydrometer'' will be replaced with ``hygrometer.''

L. Method 5 of Appendix A-3 to Part 60

    In Method 5, we erroneously finalized the reference to the Isostack
metering system in 79 FR 11228. Therefore, we will remove this
reference from section <IP_ADDRESS> and continue to issue broadly applicable
test method determinations or letters of assessments regarding whether
specific alternative metering equipment meets the specifications of the
method as was our intent in the ``Summary of Comments and Responses on
Revisions to Test Methods and Testing Regulations'' (EPA-HQ-OAR-2010-
0114-0045). The phrase ``after ensuring that all joints have been wiped
clean of silicone grease'' will be removed from section <IP_ADDRESS>.5.
Sections 10.7 and 10.8 will be added to require calibration of the
balance used to weigh impingers and to require a multipoint calibration
of the analytical balance.

M. Method 5H of Appendix A-3 to Part 60

    In Method 5H, sections 10.4 and 10.5 will be added to require
calibration of the balance used to weigh impingers and to require a
multipoint calibration of the analytical balance.

N. Method 5I of Appendix A-3 to Part 60

    In Method 5I, sections 10.1 and 10.2 will be added to require
calibration of the balance used to weigh impingers and to require a
multipoint calibration of the analytical balance.

O. Method 6C of Appendix A-4 to Part 60

    In Method 6C, due to numerous comments and questions, the language
detailing the methodology for performing interference checks in section
8.3 will be revised to clarify and streamline the procedure. We
continue to believe that the interference test need only be repeated if
major components are replaced with different model parts.

P. Method 7E of Appendix A-4 to Part 60

    In Method 7E, section 8.1.2 will be revised to be consistent with
the requirements in Performance Specification 2. In cases where the 3-
point sampling is used, the three points along the measurement line
exhibiting the highest average concentration during the stratification
test will be 0.4, 1.2, and 2.0 meters instead of 0.4, 1.0, and 2.0
meters.
    Also, in Method 7E, due to numerous comments and questions, the
language in section 8.2.7 detailing the methodology for performing
interference checks will be revised to clarify and streamline the
procedure. We continue to believe that the interference test need only
be repeated if major components are replaced with different model
parts. Also, the word ``equations'' will be replaced with ``equation''
in the sentence in section 12.8 that reads ``If desired, calculate the
total NOX concentration with a correction for converter
efficiency using equation 7E-8.''

Q. Method 10 of Appendix A-4 to Part 60

    In Method 10, sections 6.2.5 and 8.4.2 will be revised, and section
6.2.6 will be added to clarify the types of sample tanks allowed for
integrated sampling.

R. Methods 10A and 10B of Appendix A-4 to Part 60

    Methods 10A and 10B will be revised to allow the use of sample
tanks as an alternative to flexible bags for sample collection.

S. Method 15 of Appendix A-5 to Part 60

    In Method 15, section 8.3.2 will be revised to clarify the
calibrations that represent partial calibration.

T. Method 16C of Appendix A-6 to Part 60

    In Method 16C, equation 16-1C will be revised to replace
Cv (manufacturer certified concentration of a calibration
gas in ppmv SO2) in the denominator with CS (calibration
span in ppmv). Therefore, the definition of CS will be added to the
nomenclature in section 12.1, and the definition of Cv will
be deleted from the nomenclature in section 12.1.

U. Method 18 of Appendix A-6 to Part 60

    In Method 18, section <IP_ADDRESS>.2.3 will be removed because the
requirement to analyze two field audit samples as described in section
9.2 has been moved to the General Provisions.

V. Method 25C of Appendix A-7 to Part 60

    In Method 25C, section 9.1 incorrectly references section 8.4.1;
this reference will be corrected to section 8.4.2. Section 11.2 will be
deleted because the audit sample analysis is now covered under the
General Provisions. The nomenclature will be revised in section 12.1,
and equation 25C-2 will be revised in section 12.3. Sections 12.4,
12.5, 12.5.1, and 12.5.2 will be added to incorporate equations to
correct sample concentrations for ambient air dilution.

W. Method 26 of Appendix A-8 to Part 60

    In Method 26, section 13.3 will be revised to indicate the correct
method detection limit.

X. Method 26A of Appendix A-8 to Part 60

    In Method 26A, language will be added to section 4.3 indicating
that dissociating chloride salts at elevated temperatures interfere
with halogen acid measurement in this method, but maintaining
particulate probe/filter temperatures at 120+/-14 [deg]C (248+/-25
[deg]F) minimizes this interference. Sections 6.1.7 and 8.1.5 will be
revised to delete reference to other temperatures around the probe and
filter holder during sampling as specified by the applicable subpart or
approved by the Administrator for a particular application. Also, the
error in ``. . . between 120 and 134 [deg]C (248 and 275 [deg]F . .
.'') will be corrected to ``. . . between 120 and 134 [deg]C (248 and
273 [deg]F . . .'') in section 8.1.6.

Y. Method 29 of Appendix A-8 to Part 60

    In Method 29, section <IP_ADDRESS> will be revised to require rinsing
impingers containing permanganate with hydrogen chloride (HCl) to
ensure consistency with the application of Method 29 across various
stationary source categories and since there is evidence that HCl is
needed to release the mercury (Hg) bound in the precipitate from the
permanganate. Sections 10.4 and 10.5 will be added to require
calibration of the balance used to weigh impingers and to require a
multipoint calibration of the analytical balance.

Z. Method 30A of Appendix A-8 to Part 60

    In Method 30A, the heading of section 8.1 will be changed from
``Sample Point Selection.'' to ``Selection of Sampling Sites and
Sampling Points.''

AA. Method 30B of Appendix A-8 to Part 60

    In Method 30B, the heading of section 8.1 will be changed from
``Sample Point Selection.'' to ``Selection of Sampling Sites and
Sampling Points.'' In section <IP_ADDRESS>, the reference to ASTM WK223 will
be changed to ASTM D6911-15. ASTM WK223 was the draft standard that was
available at the time that Method 30B was first promulgated; it has
since been finalized to ASTM D6911-15.

BB. Appendix B to Part 60--Performance Specifications

    In the index to appendix B to part 60, Performance Specification
16--Specifications and Test Procedures for Predictive Emission
Monitoring Systems in Stationary Sources will be added.

CC. Performance Specification 1 of Appendix B to Part 60

    In Performance Specification 1, paragraph 8.1(2)(i) will be revised
to not limit the location of a continuous opacity monitoring system
(COMS) to a point at least four duct diameters downstream and two duct
diameters upstream from a control device or flow disturbance, but it
will refer to paragraphs 8.1(2)(ii) and 8.1(2)(iii) for additional
options.

DD. Performance Specification 2 of Appendix B to Part 60

    In Performance Specification 2, the definition of span value will
be revised in section 3.11. Also, in section 6.1.1, the data recorder
language will be revised. In section 16.3.2, the characters
``|dverbar'' will be replaced with d, which is the average
difference between responses and the concentration/responses. In
section 18, Table 2-2 and Figure 2-1 are attached to each other. Table
2-2 will be detached from Figure 2-1, and the figure will be labeled
``Calibration Drift Determination.''

EE. Performance Specification 3 of Appendix B to Part 60

    In Performance Specification 3, we will revise section 13.2 to
clarify how to calculate relative accuracy.

FF. Performance Specification 4A of Appendix B to Part 60

    In Performance Specification 4A, we will revise the response time
test procedure in sections 8.3 and 8.3.1. The language specifying that
the response time is a check of the entire system was previously
deleted. However, we have had several inquiries about this, and we
believe that the entire system should be checked with the response time
test procedure; therefore, we will put this requirement back into the
performance specification. We will also revise section 13.3 because we
have received information indicating that the response time of 1.5
minutes is too stringent; we will relax the response time requirement
to 2.0 minutes.

GG. Performance Specification 11 of Appendix B to Part 60

    In Performance Specification 11, equations 11-1 and 11-2 will be
revised in section 12.1, and the response range will be used in lieu of
the upscale value in section 13.1.

HH. Performance Specification 15 of Appendix B to Part 60

    In Performance Specification 15, the statement ``An audit sample is
obtained from the Administrator'' will be deleted from paragraph 9.1.2.
Also, in Performance Specification 15, reserved sections 14.0 and 15.0
will be added.

II. Performance Specification 16 of Appendix B to Part 60

    In Performance Specification 16, we will change Table 16-1 to make
be consistent with conventional statistical applications; the two
columns currently labeled ``n-1'' will be re-labeled ``n.'' We will
also revise section 12.2.3 for selection of n-1 degrees of freedom.

JJ. Procedure 2 of Appendix F to Part 60

    In Procedure 2, equations 2-2 and 2-3 in section 12.0 will be
revised to correctly define the denominator when calculating
calibration drift. Also, equation 2-4 in section 12.0 will be revised
to correctly define the denominator when calculating accuracy.

KK. General Provisions (Subpart A) Part 61

    Section 61.13(e)(1)(i) of the General Provisions of Part 61 will be
revised to add Methods 30A and 30B to the list of methods not requiring
the use of audit samples. Consistent with the criteria used in
establishing the original list of methods for which no audit samples
are required (75 FR 55636), Method 30A is an instrumental test method
that already has sufficient calibration and QA requirements. Method 30B
has sufficient performance-based QA measures including analysis of an
independent calibration standard with each set of field samples.

LL. Method 107 of Appendix B to Part 61

    In Method 107, the term ``Geon'' will be deleted from the heading
in section 11.7.3.

MM. General Provisions (Subpart A) Part 63

    The General Provisions of part 63, Sec.  63.7(c)(2)(iii)(A) will be
revised to add Methods 30A and 30B to the list of methods not requiring
the use of audit samples. Consistent with the criteria used in
establishing the original list of methods for which no audit samples
are required (75 FR 55636), Method 30A will be added because it is an
instrumental test method that already has sufficient calibration and QA
requirements, and Method 30B will be added because it has sufficient
performance-based QA measures including analysis of an independent
calibration standard with each set of field samples.
    Also in the General Provisions of part 63, Sec.  63.7(g)(2) will be
revised to require the reporting of specific emissions test data in
test reports. These data elements will be required regardless of
whether the report is submitted electronically or in paper format. We
will make these revisions 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.

NN. Method 320 of Appendix A to Part 63

    In Method 320, sections 13.1, 13.4, and 13.4.1 will be revised to
indicate the correct Method 301 reference.

IV. Request for Comments

    The Agency is reviewing the adequacy of its current test methods in
regard to sampling site selection and sampling point requirements.
Emission gas flow patterns affect representative testing, and this is
not addressed in many EPA test methods. Method 1 contains provisions
for sampling point locations, traversing, and determination of cyclonic
flow, and Method 7E was revised to contain procedures for determining
gaseous stratification in 2006. However, there are currently no
requirements in most methods for gaseous compounds to follow the Method
1 or 7E procedures.
    Method 7E allows stratification to be assessed through either a 3-
or 12-point traverse while measuring variations in either a pollutant
or diluent concentration. The degree of stratification determines
whether a single-point, 3-point, or 12-point traverse is used for the
emissions test. There are no requirements to check for cyclonic flow in
Method 7E.
    We have some information that suggests deficiencies exist in the 3-
point test in a number of cases and that at least a 5-point, dual axis
test should be required. A summary of this information has been
included in the docket for this action. We are also reconsidering the
appropriateness of measuring variations in a diluent gas for the test
instead of the regulated pollutant.
    In this rule, we propose to update the General Provisions of parts
60, 61, and 63 to include evaluations of gas stratification and
cyclonic flow with all compliance tests. The Agency solicits comments
and data to aid in establishing effective and equitable procedures.
    The Agency also requests comments on the proposed changes to the
response time test in Performance Specification 4A. The Agency has
received some information to suggest that a system response time test
criteria of less than two minutes may be difficult to accomplish.
Therefore, the Agency solicits comments and data to assist in
establishing appropriate criteria.

V. Statutory and Executive Order Reviews

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'' under the
terms of Executive Order (E.O.) 12866 (58 FR 51735, October 4, 1993)
and is, therefore, not subject to review under Executive Orders 12866
and 13563 (76 FR 3821, January 21, 2011).

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 do not add
information collection requirements but make corrections and 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. In
making this determination, the impact of concern is any significant
adverse economic impact on small entities. An agency may certify that a
rule will not have a significant economic impact on a substantial
number of small entities if the rule relieves regulatory burden, has no
net burden or otherwise has a positive economic effect on the small
entities subject to the rule. This proposed rule will not impose
emission measurement requirements beyond those specified in the current
regulations, nor does it change any emission standard. We have,
therefore, concluded that this action will have no net regulatory
burden for all directly regulated small entities.

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 simply corrects and updates 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 D6911-15 for packaging and shipping samples in Method 30B. The
ASTM D6911-15 standard provides guidance on the selection of procedures
for proper packaging and shipment of environmental samples to the
laboratory for analysis to ensure compliance with appropriate
regulatory programs and protection of sample integrity during shipment.
    The EPA proposes to use ASTM E617-13 for laboratory weights and
precision mass standards in Methods 4, 5, 5H, 5I, 29, and 202. The ASTM
E617-13 standard covers weights and mass standards used in laboratories
for specific classes.
    The ASTM D6911-15 and ASTM E617-13 standards were developed and
adopted by the American Society for Testing and Materials (ASTM). These
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.

J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

    The EPA believes the human health or environmental risk addressed
by this action will not have potential disproportionately high and
adverse human health or environmental effects on minority, low-income
or indigenous populations because it does not affect the level of
protection provided to human health or the environment.

2. Revise section 4.0 a. of appendix M to part 51 to read as follows:

Appendix M to Part 51--Recommended Test Methods for State
Implementation Plans

* * * * *
    4.0 * * *
    a. The source owner, operator, or representative of the tested
facility shall obtain an audit sample, if commercially available,
from an AASP for each test method used for regulatory compliance
purposes. No audit samples are required for the following test
methods: Methods 3A and 3C of appendix A-3 of part 60 of this
chapter, Methods 6C, 7E, 9, and 10 of appendix A-4 of part 60,
Methods 18 and 19 of appendix A-6 of part 60, Methods 20, 22, and
25A of appendix A-7 of part 60, Methods 30A and 30B of appendix A-8
of part 60, and Methods 303, 318, 320, and 321 of appendix A of part
63 of this chapter. If multiple sources at a single facility are
tested during a compliance test event, only one audit sample is
required for each method used during a compliance test. The
compliance authority responsible for the compliance test may waive
the requirement to include an audit sample if they believe that an
audit sample is not necessary. ``Commercially available'' means that
two or more independent AASPs have blind audit samples available for
purchase. If the source owner, operator, or representative cannot
find an audit sample for a specific method, the owner, operator, or
representative shall consult the EPA Web site at the following URL,
http://www.epa.gov/ttn/emc, to confirm whether there is a source
that can supply an audit sample for that method. If the EPA Web site
does not list an available audit sample at least 60 days prior to
the beginning of the compliance test, the source owner, operator, or
representative shall not be required to include an audit sample as
part of the quality assurance program for the compliance test. When
ordering an audit sample, the source owner, operator, or
representative shall give the sample provider an estimate for the
concentration of each pollutant that is emitted by the source or the
estimated concentration of each pollutant based on the permitted
level and the name, address, and phone number of the compliance
authority. The source owner, operator, or representative shall
report the results for the audit sample along with a summary of the
emission test results for the audited pollutant to the compliance
authority and shall report the results of the audit sample to the
AASP. The source owner, operator, or representative shall make both
reports at the same time and in the same manner or shall report to
the compliance authority first and then report to the AASP. If the
method being audited is a method that allows the samples to be
analyzed in the field, and the tester plans to analyze the samples
in the field, the tester may analyze the audit samples prior to
collecting the emission samples provided a representative of the
compliance authority is present at the testing site. The tester may
request and the compliance authority may grant a waiver to the
requirement that a representative of the compliance authority must
be present at the testing site during the field analysis of an audit
sample. The source owner, operator, or representative may report the
results of the audit sample to the compliance authority and then
report the results of the audit sample to the AASP prior to
collecting any emission samples. The test protocol and final test
report shall document whether an audit sample was ordered and
utilized and the pass/fail results as applicable.

    9.10 Field Train Recovery Blank. You must recover a minimum of
one field train blank for each source category tested at the
facility. You must recover the field train blank after the first or
second run of the test. You must assemble the sampling train as it
will be used for testing. Prior to the purge, you must add 100 ml of
water to the first impinger and record this data on Figure 4. You
must purge the assembled train as described in Section 8.5.3. You
must recover field train blank samples as described in Section
8.5.4. From the field sample weight, you will subtract the
condensable particulate mass you determine with this blank train or
0.002 g (2.0 mg), whichever is less.
* * * * *

10.0 Calibration and Standardization

* * * * *
    10.3 Field Balance Calibration Check. Check the calibration of
the balance used to weigh impingers with ASTM E617-13 ``Standard
Specification for Laboratory Weights and Precision Mass Standards''
Class 3 tolerance (or better) weight of at least 500g or within 50g
of a loaded impinger weight. Daily before use, the field balance
must measure the weight within  0.5 g of the certified
mass. If the daily balance calibration check fails, perform
corrective measures and repeat check before use of balance.
    10.4 Analytical Balance Calibration. Perform a multipoint
calibration (at least five points spanning the operational range) of
the analytical balance before the first use and semiannually,
thereafter. The calibration of the analytical balance must be
conducted using ASTM E617-13 ``Standard Specification for Laboratory
Weights and Precision Mass Standards'' Class 2 (or better) tolerance
weights. Audit the balance each day it is used for gravimetric
measurements by weighing at least one ASTM E617-13 Class 2 tolerance
(or better) calibration weight that corresponds to 50 to 150 percent
of the weight of one filter or 5 g. If the scale cannot reproduce
the value of the calibration weight to within 0.5 mg of the
certified mass, perform corrective measures, and conduct the
multipoint calibration before use.

11.0 Analytical Procedures

* * * * *
    11.2.2 * * *
    <IP_ADDRESS> Determine the inorganic fraction weight. Transfer the
aqueous fraction from the extraction to a clean 500-ml or smaller
beaker. Evaporate to no less than 10 ml liquid on a hot plate or in
the oven at 105 [deg]C and allow to dry at room temperature (not to
exceed 30 [deg]C (85[emsp14][deg]F)). You must ensure that water and
volatile acids have completely evaporated before neutralizing
nonvolatile acids in the sample. Following evaporation, desiccate
the residue for 24 hours in a desiccator containing anhydrous
calcium sulfate. Weigh at intervals of at least 6 hours to a
constant weight. (See Section 3.0 for a definition of Constant
weight.) Report results to the nearest 0.1 mg on the CPM Work Table
(see Figure 6 of Section 18) and proceed directly to Section 11.2.3.
If the residue cannot be weighed to constant weight, re-dissolve the
residue in 100 ml of deionized distilled ultra-filtered water that
contains 1 ppmw (1 mg/L) residual mass or less and continue to
Section <IP_ADDRESS>.
    <IP_ADDRESS> Use titration to neutralize acid in the sample and
remove water of hydration. If used, calibrate the pH meter with the
neutral and acid buffer solutions. Then titrate the sample with 0.1N
NH4OH to a pH of 7.0, as indicated by the pH meter or colorimetric
indicator. Record the volume of titrant used on the CPM Work Table
(see Figure 6 of Section 18).
    <IP_ADDRESS> Using a hot plate or an oven at 105 [deg]C, evaporate
the aqueous phase to approximately 10 ml. Quantitatively transfer
the beaker contents to a clean, 50-ml pre-tared weighing tin and
evaporate to dryness at room temperature (not to exceed 30 [deg]C
(85 [deg]F)) and pressure in a laboratory hood. Following
evaporation, desiccate the residue for 24 hours in a desiccator
containing anhydrous calcium sulfate. Weigh at intervals of at least
6 hours to a constant weight. (See Section 3.0 for a definition of
Constant weight.) Report results to the nearest 0.1 mg on the CPM
Work Table (see Figure 6 of Section 18).
    <IP_ADDRESS> Calculate the correction factor to subtract the
NH4\+\ retained in the sample using Equation 1 in Section
12.

    3.3 Calibration Gases. For nitrogen oxides monitoring systems
installed on fossil fuel-fired steam generators, the pollutant gas
used to prepare calibration gas mixtures (Section 6.1, Performance
Specification 2, appendix B, part 60 of this chapter) shall be
nitric oxide (NO). For nitrogen oxides monitoring systems, installed
on nitric acid plants the pollutant gas used to prepare calibration
gas mixtures (Section 6.1, Performance Specification 2, appendix B,
part 60) shall be nitrogen dioxide (NO2). These gases
shall also be used for daily checks under paragraph 3.7 of this
appendix as applicable. For sulfur dioxide monitoring systems
installed on fossil fuel-fired steam generators or sulfuric acid
plants, the pollutant gas used to prepare calibration gas mixtures
(Section 6.1, Performance Specification 2, appendix B, part 60)
shall be sulfur dioxide (SO2). Span and zero gases should
be traceable to National Bureau of Standards reference gases
whenever these reference gases are available. Every 6 months from
date of manufacture, span and zero gases shall be reanalyzed by
conducting triplicate analyses using the reference methods in
appendix A, part 60, as follows: For SO2, use Reference
Method 6; for nitrogen oxides, use Reference Method 7; and for
carbon dioxide or oxygen, use Reference Method 3. The gases may be
analyzed at less

frequent intervals if longer shelf lives are guaranteed by the
manufacturer.
* * * * *
    5.1.3 The values used in the equations under paragraph 5.1 are
derived as follows:
    E = pollutant emission, g/million cal (lb/million BTU),
    C = pollutant concentration, g/dscm (lb/dscf), determined by
multiplying the average concentration (ppm) for each hourly period
by 4.16x10-5 M g/dscm per ppm (2.64x 10-9 M
lb/dscf per ppm) where M = pollutant molecular weight, g/g-mole (lb/
lb-mole). M = 64 for sulfur dioxide and 46 for oxides of nitrogen.
    %O2, %CO2 = Oxygen or carbon dioxide
volume (expressed as percent) determined with equipment specified
under paragraphs 3.1.4 and 3.1.5 of this appendix.

    (f) Unless otherwise specified in the applicable subpart, each
performance test shall consist of three separate runs using the
applicable test method.
    (1) Each run shall be conducted for the time and under the
conditions specified in the applicable standard. For the purpose of
determining compliance with an applicable standard, the arithmetic
means of results of the three runs shall apply. In the event that a
sample is accidentally lost or conditions occur in which one of the
three runs must be discontinued because of forced shutdown, failure of
an irreplaceable portion of the sample train, extreme meteorological
conditions, or other circumstances, beyond the owner or operator's
control, compliance may, upon the Administrator's approval, be
determined using the arithmetic mean of the results of the two other
runs.
    (2) Contents of report (electronic or paper submitted copy). Unless
otherwise specified in a relevant standard or test method, or as
otherwise approved by the Administrator in writing, results of a
performance test shall include general identification information for
the facility including a mailing address, the actual address, the owner
or operator or responsible official (where they are applicable) or an
appropriate representative and an email address for this person, and
the appropriate Federal Registry System (FRS) number for the facility;
the purpose of the test including the regulation requiring the test,
the pollutant being measured, the units of the standard or the
pollutant emissions units, and any process parameter component; a brief
process description; a complete unit description, including a
description of feed streams and control devices, the appropriate source
classification code (SCC), and the latitude and longitude of the

Appendix A-1 to Part 60--Test Methods 1 through 2F

* * * * *

Method 1--Sample and Velocity Traverses for Stationary Sources

* * * * *

11.0 Procedure

* * * * *
    <IP_ADDRESS> When the eight- and two-diameter criterion cannot be
met, the minimum number of traverse points is determined from Figure
1-1. Before referring to the figure, however, determine the
distances from the measurement site to the nearest upstream and
downstream disturbances, and divide each distance by the stack
diameter or equivalent diameter, to determine the distance in terms
of the number of duct diameters.
* * * * *

Method 2--Determination of Stack Gas Velocity and Volumetric Flow Rate
(Type S Pitot Tube)

* * * * *

6.0 Equipment and Supplies

* * * * *
    6.7 Calibration Pitot Tube. Calibration of the Type S pitot tube
requires a standard Pitot tube for a reference.
* * * * *

10.0 Calibration and Standardization

* * * * *
    <IP_ADDRESS> The flow system shall have the capacity to generate a
test-section velocity around 910 m/min (3,000 ft/min). This velocity
must be constant with time to guarantee constant and steady flow
during the entire period of calibration. A centrifugal fan is
recommended for this purpose, as no flow rate adjustment for back
pressure of the fan is allowed during the calibration process. Note
that Type S pitot tube coefficients obtained by single-velocity
calibration at 910 m/min (3,000 ft/min) will generally be valid to
3 percent for the measurement of velocities above 300 m/
min (1,000 ft/min) and to 6 percent for the measurement
of velocities between 180 and 300 m/min (600 and 1,000 ft/min). If a
more precise correlation between the pitot tube coefficient, (Cp),
and velocity is desired, the flow system should have the capacity to
generate at least four distinct, time-invariant test-section
velocities covering the velocity range from 180 to 1,500 m/min (600
to 5,000 ft/min), and calibration data shall be taken at regular
velocity intervals over this range (see References 9 and 14 in
section 17.0 for details).
* * * * *
    <IP_ADDRESS> Read [Delta]pstd, and record its value in a
data table similar to the one shown in Figure 2-9. Remove the
standard pitot tube from the duct, and disconnect it from the
manometer. Seal the standard entry port. Make no adjustment to the
fan speed or other wind tunnel volumetric flow control device
between this reading and the corresponding Type S pitot reading.
* * * * *
    <IP_ADDRESS> Repeat Steps <IP_ADDRESS> through <IP_ADDRESS> until three
pairs of [Delta]p readings have been obtained for the A side of the
Type S pitot tube, with all the paired observations conducted at a
constant fan speed (no changes to fan velocity between observed
readings).
* * * * *
    <IP_ADDRESS>.3 For Type S pitot tube combinations with complete
probe assemblies, the calibration point should be located at or near
the center of the duct; however, insertion of a probe sheath into a
small duct may cause significant cross-sectional area interference
and blockage and yield incorrect coefficient values (Reference 9 in
section 17.0). Therefore, to minimize the blockage effect, the
calibration point may be a few inches off-center if necessary, but
no closer to the outer wall of the wind tunnel than 4 inches. The
maximum allowable blockage, as determined by a projected-area model
of the probe sheath, is 2 percent or less of the duct cross-
sectional area (Figure 2-10a). If the pitot and/or probe assembly
blocks more than 2 percent of the cross-sectional area at an
insertion point only 4 inches inside the wind tunnel, the diameter
of the wind tunnel must be increased.
* * * * *
    <IP_ADDRESS> For a probe assembly constructed such that its pitot
tube is always used in the same orientation, only one side of the
pitot tube need be calibrated (the side which will face the flow).
The pitot tube must still meet the alignment specifications of
Figure 2-2 or 2-3, however, and must have an average

deviation ([sigma]) value of 0.01 or less (see section 12.4.4).

Method 2G--Determination of Stack Gas Velocity and Volumetric Flow Rate
With Two-Dimensional Probes

* * * * *

6.0 Equipment and Supplies

* * * * *
    6.11.1 Test section cross-sectional area. The flowing gas stream
shall be confined within a circular, rectangular, or elliptical
duct. The cross-sectional area of the tunnel must be large enough to
ensure fully developed flow in the presence of both the calibration
pitot tube and the tested probe. The calibration site, or ``test
section,'' of the wind tunnel shall have a minimum diameter of 30.5
cm (12 in.) for circular or elliptical duct cross-sections or a
minimum width of 30.5 cm (12 in.) on the shorter side for
rectangular cross-sections. Wind tunnels shall meet the probe
blockage provisions of this section and the qualification
requirements prescribed in section 10.1. The projected area of the
portion of the probe head, shaft, and attached devices inside the
wind tunnel during calibration shall represent no more than 2
percent of the cross-sectional area of the tunnel. If the pitot and/
or probe assembly blocks more than 2 percent of the cross-sectional
area at an insertion point only 4 inches inside the wind tunnel, the
diameter of the wind tunnel must be increased.
    6.11.2 Velocity range and stability. The wind tunnel should be
capable of achieving and maintaining a constant and steady velocity
between 6.1 m/sec and 30.5 m/sec (20 ft/sec and 100 ft/sec) for the
entire calibration period for each selected calibration velocity.
The wind tunnel shall produce fully developed flow patterns that are
stable and parallel to the axis of the duct in the test section.
* * * * *

10.0 Calibration

* * * * *
    10.6.6 Read the differential pressure from the calibration pitot
tube ([Delta]Pstd), and record its value. Read the
barometric pressure to within 2.5 mm Hg (0.1
in. Hg) and the temperature in the wind tunnel to within 0.6[deg]C
(1[emsp14][deg]F). Record these values on a data form similar to
Table 2G-8. Record the rotational speed of the fan or indicator of
wind tunnel volumetric flow and make no adjustment to fan speed or
wind tunnel flow control between this observation and the Type S
probe reading.
* * * * *
    10.6.8 Take paired differential pressure measurements with the
calibration pitot tube and tested probe (according to sections
10.6.6 and 10.6.7). The paired measurements in each replicate can be
made either simultaneously (i.e., with both probes in the wind
tunnel) or by alternating the measurements of the two probes (i.e.,
with only one probe at a time in the wind tunnel). Adjustments made
to the fan speed or other changes to the system designed to change
the air flow velocity of the wind tunnel between observation of the
calibration pitot tube ([Delta]Pstd) and the Type S pitot
tube invalidates the reading and the observation must be repeated.

6. Analysis

* * * * *
    6.3 Analyzer Linearity Check and Calibration. Perform this test
before sample analysis.
    6.3.1 Using the gas mixtures in section 5.1, verify the detector
linearity over the range of suspected sample concentrations with at
least three concentrations per

compound of interest. This initial check may also serve as the
initial instrument calibration.
    6.3.2 You may extend the use of the analyzer calibration by
performing a single point calibration verification. Calibration
verifications shall be performed by triplicate injections of a
single-point standard gas. The concentration of the single-point
calibration must either be at the midpoint of the calibration curve
or at approximately the source emission concentration measured
during operation of the analyzer.
    6.3.3 Triplicate injections must agree within 5 percent of their
mean, and the average calibration verification point must agree
within 10 percent of the initial calibration response factor. If
these calibration verification criteria are not met, the initial
calibration described in section 6.3.1, using at least three
concentrations, must be repeated before analysis of samples can
continue.
    6.3.4 For each instrument calibration, record the carrier and
detector flow rates, detector filament and block temperatures,
attenuation factor, injection time, chart speed, sample loop volume,
and component concentrations.
    6.3.5 Plot a linear regression of the standard concentrations
versus area values to obtain the response factor of each compound.
Alternatively, response factors of uncorrected component
concentrations (wet basis) may be generated using instrumental
integration.

    Note:  Peak height may be used instead of peak area throughout
this method.

Method 4--Determination of Moisture Content in Stack Gases

* * * * *

10.0 Calibration and Standardization

* * * * *
    10.3 Field Balance Calibration Check. Check the calibration of
the balance used to weigh impingers using ASTM E617-13 ``Standard
Specification for Laboratory Weights and Precision Mass Standards''
(incorporated by reference--see 40 CFR 60.17) Class 3 tolerance (or
better) weight of at least 500g or within 50g of a loaded impinger
weight. Daily before use, the field balance must measure the weight
within 0.5g of the certified mass. If the daily balance
calibration check fails, perform corrective measures and repeat
check before use of balance.
* * * * *

12.0 Data Analysis and Calculations

* * * * *
    12.2.5 Using F-factors to determine approximate moisture for
estimating moisture content where no wet scrubber is being used, for
the purpose of determining isokinetic sampling rate settings with no
fuel sample is acceptable using the average Fc or
Fd factor from Method 19 (see Method 19, section 12.3.1).
If this option is selected, calculate the approximate moisture as
follows:
BWS = BH + BA + BF
Where:
BA = Mole Fraction of moisture in the ambient air.
[GRAPHIC] [TIFF OMITTED] TP08SE15.004

BF = Mole fraction of moisture from free water in the
fuel.
[GRAPHIC] [TIFF OMITTED] TP08SE15.005

BH <= Mole fraction of moisture from the hydrogen in the
fuel.
[GRAPHIC] [TIFF OMITTED] TP08SE15.006

Bws = Mole fraction of moisture in the stack gas.
Fd = Volume of dry combustion components per unit of heat
content at 0 percent oxygen, dscf/106
    Btu (scm/J). See Table 19-2 in Method 19.
Fw = Volume of wet combustion components per unit of heat
content at 0 percent oxygen, wet
    scf/10\6\ Btu (scm/J). See Table 19-2 in Method 19.
%RH = Percent relative humidity (calibrated hydrometer acceptable),
percent.
PBar = Barometric pressure, in. Hg.
T = Ambient temperature, [deg]F.
W = Percent free water by weight, percent.
O2 = Percent oxygen in stack gas, dry basis, percent.
* * * * *

16.0 Alternative Procedures

* * * * *
    16.4 Using F-factors to determine moisture is an acceptable
alternative to Method 4 for a combustion stack not using a scrubber
and where a fuel sample is taken during the test run and analyzed
for development of an Fd factor (see Method 19, section
12.3.2) and where stack O2 content is measured by Method
3A or 3B during each test run.
    If this option is selected, calculate the moisture content as
follows:
BWS = BH + BA + BF
Where:
BA = Mole fraction of moisture in the ambient air.

[GRAPHIC] [TIFF OMITTED] TP08SE15.007

    Note:  Values of BA should be between 0.00 and 0.06
with common values being about 0.015.

BF = Mole fraction of moisture from free water in the
fuel.
[GRAPHIC] [TIFF OMITTED] TP08SE15.008

    Note: Free water in fuel is minimal for distillate oil and
gases, such as propane and natural gas, so this step may be omitted
for those fuels.

BH = Mole fraction of moisture from the hydrogen in the
fuel.
[GRAPHIC] [TIFF OMITTED] TP08SE15.009

Bws = Mole fraction of moisture in the stack gas.
Fd = Volume of dry combustion components per unit of heat
content at 0 percent oxygen, dscf/10\6\ Btu (scm/J). Develop a test
specific Fd value using an integrated fuel sample from
each test run and Equation 19-3 in section 12.3.2 of Method 19.
FW = Volume of wet combustion components per unit of heat
content at 0 percent oxygen, wet scf/10\6\ Btu (scm/J). Develop a
test specific FW value using an integrated fuel sample
from each test run and Equation 19-4 in section 12.3.2 of Method 19.
%RH = Percent relative humidity (calibrated hygrometer acceptable),
percent.
PBar = Barometric pressure, in. Hg.
T = Ambient temperature, [deg]F.

    <IP_ADDRESS> Metering System. Vacuum gauge, leak-free pump,
calibrated temperature sensors (rechecked at at least one point
after each test), dry gas meter (DGM) capable of measuring volume to
within 2 percent, and related equipment, as shown in Figure 5-1.
Other metering systems capable of maintaining sampling rates within

8.0 Sample Collection, Preservation, Storage, and Transport

* * * * *
    <IP_ADDRESS>.5 Clean the inside of the front half of the filter
holder by rubbing the surfaces with a Nylon bristle brush and
rinsing with acetone. Rinse each surface three times or more if
needed to remove visible particulate. Make a final rinse of the
brush and filter holder. Carefully rinse out the glass cyclone, also
(if applicable). After all acetone washings and particulate matter
have been collected in the sample container, tighten the lid on the
sample container so that acetone will not leak out when it is
shipped to the laboratory. Mark the height of the fluid level to
allow determination of whether leakage occurred during transport.
Label the container to identify clearly its contents.

    10.7 Field Balance Calibration Check. Check the calibration of
the balance used to weigh impingers using ASTM E617-13 ``Standard

(incorporated by reference--see 40 CFR 60.17) Class 3 tolerance (or
better) weight of at least 500g or within 50g of a loaded impinger
weight. Daily before use, the field balance must measure the weight
within 0.5g of the certified mass. If the daily balance
calibration check fails, perform corrective measures and repeat

    10.8 Analytical Balance Calibration. Perform a multipoint
calibration (at least five points spanning the operational range) of
the analytical balance before the first use and semiannually,
thereafter. The calibration of the analytical balance must be

at least one ASTM E617-13 Class 2 tolerance (or better) calibration
weight) that corresponds to 50 to 150 percent of the weight of one
filter or 5g. If the scale cannot reproduce the value of the
calibration weight to within 0.5 mg of the certified mass, perform
corrective measures, and conduct the multipoint calibration before
use.

    8.3 Interference Check. You must follow the procedures of
section 8.2.7 of Method 7E to conduct an interference check,
substituting SO2 for NOX as the method
pollutant. For dilution-type measurement systems, you must use the
alternative interference check procedure in section 16 and a co-

8.0 Sample Collection, Preservation, Storage, and Transport

* * * * *
    8.1.2 Determination of Stratification. Perform a stratification
test at each test site to determine the appropriate number of sample
traverse points. If testing for multiple pollutants or diluents at
the same site, a stratification test using only one pollutant or
diluent satisfies this requirement. A stratification test is not
required for small stacks that are less than 4 inches in diameter.
To test for stratification, use a probe of appropriate length to
measure the NOX (or pollutant of interest) concentration
at twelve traverse points located according to Table 1-1 or Table 1-
2 of Method 1. Alternatively, you may measure at three points on a
line passing through the centroidal area. Space the three points at
16.7, 50.0, and 83.3 percent of the measurement line. Sample for a
minimum of twice the system response time (see section 8.2.6) at
each traverse point. Calculate the individual point and mean
NOX concentrations. If the concentration at each traverse
point differs from the mean concentration for all traverse points by
no more than: (a)  5.0 percent of the mean
concentration; or (b)  0.5 ppm (whichever is less
restrictive), the gas stream is considered unstratified and you may
collect samples from a single point that most closely matches the
mean. If the 5.0 percent or 0.5 ppm criterion is not met, but the
concentration at each traverse point differs from the mean
concentration for all traverse points by not more than: (a) 10.0 percent of the mean; or (b) 1.0 ppm
(whichever is less restrictive), the gas stream is considered to be
minimally stratified, and you may take samples from three points.
Space the three points at 16.7, 50.0, and 83.3 percent of the
measurement line. Alternatively, if a twelve-point stratification
test was performed and the emissions were shown to be minimally
stratified (all points within  10.0 percent of their
mean or within  1.0 ppm), and if the stack diameter (or
equivalent diameter, for a rectangular stack or duct) is greater
than 2.4 meters (7.8 ft), then you may use 3-point sampling and
locate the three points along the measurement line exhibiting the
highest average concentration during the stratification test, at
0.4, 1.2 and 2.0 meters from the stack or duct wall. If the gas
stream is found to be stratified because the 10.0 percent or 1.0 ppm
criterion for a 3-point test is not met, locate twelve traverse
points for the test in accordance with Table 1-1 or Table 1-2 of
Method 1.
* * * * *
    8.2.7 Interference Check. Conduct an interference response test
of the gas analyzer prior to its initial use in the field. If you
have multiple analyzers of the same make and model, you need only
perform this alternative interference check on one analyzer. You may
also meet the interference check requirement if the instrument
manufacturer performs this or a similar check on an analyzer of the
same make and model of the analyzer that you use and provides you
with documented results.

    8.4.2 Integrated Sampling. Evacuate the flexible bag or sample
tank. Set up the equipment as shown in Figure 10-1 with the bag
disconnected. Place the probe in the stack and purge the sampling
line. Connect the bag, making sure that all connections are leak-
free. Sample at a rate proportional to the stack velocity. If
needed, the CO2 content of the gas may be determined by
using the

Method 3 integrated sample procedures, or by weighing an ascarite
CO2 removal tube used and computing CO2
concentration from the gas volume sampled and the weight gain of the
tube. Data may be recorded on a form similar to Table 10-1. If a
sample tank is used for sample collection, follow procedures similar
to those in sections 8.1.2, 8.2.3, 8.3, and 12.4 of Method 25 as
appropriate to prepare the tank, conduct the sampling, and correct
the measured sample concentration.

    8.1 Sample Bag or Tank Leak-Checks. While a leak-check is
required after bag or sample tank use, it should also be done before
the bag or sample tank is used for sample collection. The tank
should be leak-checked according to the procedure specified in
section 8.1.2 of Method 25. The bag should be leak-checked in the
inflated and deflated condition according to the following
procedure:
* * * * *
    8.2.1 Evacuate and leak check the sample bag or tank as
specified in section 8.1. Assemble the apparatus as shown in Figure
10A-1. Loosely pack glass wool in the tip of the probe. Place 400 ml
of alkaline permanganate solution in the first two impingers and 250
ml in the third. Connect the pump to the third impinger, and follow
this with the surge tank, rate meter, and 3-way valve. Do not
connect the bag or sample tank to the system at this time.
* * * * *
    8.2.3 Purge the system with sample gas by inserting the probe
into the stack and drawing the sample gas through the system at 300
ml/min  10 percent for 5 minutes. Connect the evacuated
bag or sample tank to the system, record the starting time, and
sample at a rate of 300 ml/min for 30 minutes, or until the bag is
nearly full, or the sample tank reaches ambient pressure. Record the
sampling time, the barometric pressure, and the ambient temperature.
Purge the system as described above immediately before each sample.

partial recalibration using the procedures in section 10.0. Only
H2S (or other permeant) need be used to recalibrate the
GC/FPD analysis system and the dilution system. Partial
recalibration may be performed at the midlevel calibration gas
concentration or at a concentration measured in the samples but not
less than the lowest calibration standard used in the initial
calibration. Compare the calibration curves obtained after the runs
to the calibration curves obtained under section 10.3. The
calibration drift should not exceed the limits set forth in section
13.4. If the drift exceeds this limit, the intervening run or runs
should be considered invalid. As an option, the calibration data set
which gives the highest sample values may be chosen by the tester.

Method 26--Determination of Hydrogen Chloride Emissions From Stationary
Sources

* * * * *

13.0 Method Performance

* * * * *
    13.3 Detection Limit. A typical IC instrumental detection limit
for C1- is 0.2 [mu]g/ml. Detection limits for the other
analyses should be similar. Assuming 50 ml liquid recovered from
both the acidified impingers, and the basic impingers, and 0.12 dscm
of stack gas sampled, then the analytical detection limit in the
stack gas will be about 0.05 ppm for HCl and Cl2,
respectively.

Method 26A--Determination of Hydrogen Halide and Halogen Emissions From
Stationary Sources Isokinetic Method

4.0 Interferences

* * * * *
    4.3 Dissociating chloride salts (e.g., ammonium chloride) at
elevated temperatures interfere with halogen acid measurement in
this method. Maintaining particulate probe/filter temperatures at
120  14 [deg]C (248  25 [deg]F) minimizes
this interference.
* * * * *

6.0. Equipment and Supplies

* * * * *
    6.1.7 Heating System. Any heating system capable of monitoring
and maintaining temperature around the filter shall be used to
ensure a sample gas temperature exiting the filter of 120  14 [deg]C (248  25 [deg]F) during sampling or
such other temperature as specified by an applicable subpart of the
standards. The monitoring and regulation of the temperature around
the filter may be done with the filter temperature sensor or another
temperature sensor.
* * * * *

8.0 Sample Collection, Preservation, Storage, and Transport

* * * * *
    8.1.5 Sampling Train Operation. Follow the general procedure
given in Method 5, section 8.5. Maintain a temperature around the
probe, through the filter (and cyclone, if used) of 120
14 [deg]C (248  25 [deg]F) or such other temperature as
specified by an applicable subpart of the standards to avoid
dissociating halogen salts and to maintain acid gases in the vapor
phase since it is extremely difficult to purge acid gases off these
components. (These components are not quantitatively recovered and
hence any collection of acid gases on these components will result
in potential under reporting these emissions.) For each run, record
the data required on a data sheet such as the one shown in Method 5,
Figure 5-3. If the condensate impinger becomes too full, it may be
emptied, recharged with 50 ml of 0.1 N H2SO4,
and replaced during the sample run. The condensate emptied must be
saved and included in the measurement of the volume of moisture
collected and included in the sample for analysis. The additional 50
ml of absorbing reagent must also be considered in calculating the
moisture. Before the sampling train integrity is compromised by
removing the impinger, conduct a leak-check as described in Method
5, section 8.4.2.
    8.1.6 Post-Test Moisture Removal (Optional). When the optional
cyclone is included in the sampling train or when liquid is visible
on the filter at the end of a sample run even in the absence of a
cyclone, perform the following procedure. Upon completion of the
test run, connect the ambient air conditioning tube at the probe
inlet and operate the train with the filter heating system between
120 and 134 [deg]C (248 and 273 [deg]F) at a low flow rate (e.g.,
[Delta]H = 1 in. H2O) to vaporize any liquid and hydrogen
halides in the cyclone or on the filter and pull them through the
train into the impingers. After 30 minutes, turn off the flow,
remove the conditioning tube, and examine the cyclone and filter for
any visible liquid. If liquid is visible, repeat this step for 15
minutes and observe again. Keep repeating until the cyclone is dry.

    Note: It is critical that this is repeated until the cyclone is
completely dry.

Method 29--Determination of Metals Emissions From Stationary Sources

* * * * *

8.0 Sample Collection, Preservation, Transport, and Storage

* * * * *
    <IP_ADDRESS> Wash the two permanganate impingers with 25 ml of 8 N
HCl, and place the wash in a separate sample container labeled No.
5C containing 200 ml of water. First, place 200 ml of water in the
container. Then wash the impinger walls and stem with the 8 N HCl by
turning the impinger on its side and rotating it so that the HCl
contacts all inside surfaces. Use a total of only 25 ml of 8 N HCl
for rinsing both permanganate impingers combined. Rinse the first
impinger, then pour the actual rinse used for the first impinger
into the second impinger for its rinse. Finally, pour the 25 ml of 8
N HCl rinse carefully into the container with the 200 ml of water.
Mark the height of the fluid level on the outside of the container
in order to determine if leakage occurs during transport.
* * * * *

10.0 Calibration and Standardization

* * * * *
    10.4 Field Balance Calibration Check. Check the calibration of
the balance used to weigh impingers using ASTM E617-13 ``Standard
Specification for Laboratory Weights and Precision Mass Standards''
(incorporated by reference--see 40 CFR 60.17) Class 3 tolerance (or
better) weight of at least 500g or within 50g of a loaded impinger
weight. Daily before use, the field balance must measure the weight
within  0.5g of the certified mass. If the daily balance
calibration check fails, perform corrective measures and repeat
check before use of balance.
    10.5 Analytical Balance Calibration. Perform a multipoint
calibration (at least five points spanning the operational range) of
the analytical balance before the first use and semiannually,
thereafter. The calibration of the analytical balance must be
conducted using ASTM E617-13 ``Standard Specification for Laboratory
Weights and Precision Mass Standards'' (incorporated by reference--
see 40 CFR 60.17) Class 2 (or better) tolerance weights. Audit the
balance each day it is used for gravimetric measurements by weighing
at least one ASTM E617-13 Class 2 tolerance (or better) calibration
weight that corresponds to 50 to 150 percent of the weight of one
filter or 5 g. If the scale cannot reproduce the value of the
calibration weight to within 0.5 mg of the certified mass, perform
corrective measures, and conduct the multipoint calibration before
use.

    <IP_ADDRESS> Sample Handling, Preservation, Storage, and Transport.
While the performance criteria of this approach provides for
verification of appropriate sample handling, it is still important
that the user consider, determine, and plan for suitable sample
preservation, storage, transport, and holding times for these
measurements. Therefore, procedures in ASTM D6911-15 ``Standard
Guide for Packaging and Shipping Environmental Samples for
Laboratory Analysis'' (incorporated by reference--see 40 CFR 60.17)
shall be followed for all samples, where appropriate.
