Amendments for Testing and Monitoring Provisions
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule: amendments.
-----------------------------------------------------------------------
SUMMARY: In this rule, we, the Environmental Protection Agency (EPA)
are making final minor amendments to our stationary source testing and
monitoring rules. These amendments include miscellaneous editorial
changes and technical corrections that are needed. We are also
promulgating Performance Specification 15, which contains the criteria
for certifying continuous emission monitoring systems (CEMS) that use
fourier transform infrared spectroscopy (FTIR). In addition, we are
changing the outline of the test methods and CEMS performance
specifications already listed in Parts 60, 61, and 63 to fit a new
format recommended by the Environmental Monitoring Management Council
(EMMC). The editorial changes and technical corrections update the
rules and help maintain their original intent. Performance
Specification 15 will provide the needed acceptance criteria for FTIR
CEMS as they emerge as a new technology. We are reformatting the test
methods and performance specifications to make them more uniform in
content and interchangeable with other Agency methods. The amendments
apply to a large number of industries that are already subject to the
current provisions of Parts 60, 61, and 63. Therefore, we have not
listed specific affected industries or their Standard Industrial
Classification codes here.
DATES: Effective Date. This regulation is effective October 17, 2000.
The incorporation by reference of certain publications listed in the
rule is approved by the Director of the Federal Register as of October
17, 2000.

I. Why Were These Amendments Made?
We have compiled miscellaneous errors and editions that are needed
for the test methods, performance specifications, and associated
regulations in 40 CFR Parts 60, 61, and 63. The corrections and
revisions consist primarily of typographical errors, technical errors
in equations and diagrams, and narrative that is no longer applicable
or is obsolete. Some of the revisions were brought to our attention by
the public. The major changes to the rule proposed on August 27, 1997
that resulted from public comments are discussed in Section III. Please
note that, although numerous technical corrections were made to Parts
60, 61, and 63 rules, none affected a compliance standard or reporting
or recordkeeping requirement. Revisions were only made to sections that
pertain to source testing or monitoring of emissions and operations.
II. What Does the New EMMC Format for Methods Look Like?
The new EMMC format we have adopted for analytical methods was
developed by consensus and will help integrate make consistent the test
methods written by different EPA programs. The test methods and
performance specifications being restructured in the new format are
shown in Table 1.

III. What Were the Significant Public Comments and What Resulting
Changes Were Made Since Proposal?
We asked that public comments on the August 27, 1997 proposal (62
FR 45369) be submitted by October 27, 1997. On November 18, 1997, we
reopened (62 FR 61483) the comment period to allow additional time for
review and comment. We received comments from facility owners and
operators, trade associations, State and Local air pollution control
agencies, environmental consultants, and private citizens. Their
comments were considered in developing this final action. A detailed
discussion of all comments are contained in the Summary of Comments and
Responses Document (see ADDRESSES section of this preamble). The major
public comments and the Agency's responses are summarized below.
A. Update to ASTM Methods
Several commenters supported our updating the references to ASTM
Standards to include the dates of the most recent versions. However,
some were concerned that updated standards not supplant the versions
previously allowed and those promulgated with the original regulation.
The ASTM recommended we follow the tradition of other governmental
agencies and list only the latest version of each standard. This would
present the latest, most improved standard. They felt that previously
approved versions would still be acceptable for future use, and this
could be noted in the preamble to the final rule.
On January 14, 1998, we published a supplementary Federal Register
notice to solicit public comments on this idea. We received three
comment letters. All commenters objected to the idea of listing only
the latest version of the ASTM standard. The commenters noted problems
that would be encountered with State Implementation Plans (SIP) wherein
only the specific ASTM standards listed in the subparts would be
allowed. They feared that listing only the latest version of the
standard would change the current allowance to use earlier versions.
This could potentially change the intent of the original emission
standard. Most commenters didn't think a preamble explanation was
sufficient assurance for continued allowance of earlier versions since
preambles are not published in the Code of Federal Regulations. There
were additional concerns for laboratories using currently acceptable
versions who would need to upgrade their practice to reflect the latest
version of a standard. The commenters were not amenable to only listing
the latest standard unless
[[Page 61746]]
language were added to the General Provisions of each part stating that
previously allowed versions of the standards were still allowed at the
discretion of the source. We feel the commenters have valid concerns
and have decided to continue the convention of listing all acceptable
versions of the ASTM standards including the new updates. The intent of
this action is to allow any of the yearly-designated versions of a
specific standard to be used in the applications where cited.
B. Performance Requirements for Continuous Instrumental Methods of Part
60--Methods 3A, 6C, 7E, 10, and 20
Several commenters thought the preamble language for this proposal
gave inadequate notice of the changes being made. Commenters stated
that, in the proposal, we did not provide an adequate basis and purpose
statement and misled the readers into thinking that the proposal
contained no substantive changes to these test methods. Based on the
number of substantive changes in this proposal, and in light of the
Section 307(d) requirements, the commenters felt that we must address
these issues in a new proposal before the revisions can go final with
the rest of the package. We agree with the commenters that the preamble
to the proposed rule may not have given adequate public notice for some
of the revisions. The revisions to the continuous instrumental methods
(Methods 3A, 6C, 7E, 10, and 20) may be considered substantive, but
were not enumerated in the preamble nor was a supporting rationale
given. Therefore, the revisions to Methods 3A, 6C, 7E, 10, and 20 will
be reproposed as a separate rule. The comments already received on the
proposal of these methods will be held for consideration with any
future comments that result from the reproposal.
C. Method 18 (Part 60, Appendix A)
One commenter thought Method 18 was difficult to follow. The
commenter suggested that, to simplify organization of the method, we
should divide the method into five categories. Each title would begin
with ``Measurement of Gaseous Organic Compounds by Gas Chromatography''
but have the following subtitles:
18A--Evacuated container sampling procedure.
18B--Bag sampling procedure.
18C--Direct interface procedure.
18D--Dilution interface procedure.
18E--Adsorption tube sampling procedure.
Another commenter suggested dividing the method into two different
methods, one for the direct extractive technique, and the other for
sample collection into bags, flasks, or adsorbents.
The method is currently divided according to the various sampling
procedures; for example, Section 8.2.2 is the Direct Interface Sampling
and Analysis Procedures, Section 8.2.3 is Dilution Interface Sampling
and Analysis Procedures, and so on. We do not believe that multiple
sampling procedures warrant dividing Method 18 into separate methods.
We feel a single method allowing different procedures offers the source
greater flexibility than citing specific procedures for particular
situations. One commenter noted that the proposed method requires
triplicate injections for analysis of the calibration standards used
for preparing the pre-test calibration curve, triplicate injections of
the test samples, and triplicate injections for construction of the
post-test calibration curve. The commenter questioned the additional
accuracy expected for the extra hours spent in sample analysis and
calibration while in the field conducting a source test compared to the
current method which requires two consecutive analyses for pre- and
post-test calibration and sample analyses meeting the same criteria for
acceptance. We are increasing the calibration requirement to triple
injections to tighten the method's quality assurance procedures.
Triplicate calibration injections is the normal procedure prevalent in
the analytical community, as well as in other Agency methodologies. It
is difficult to establish precision and accuracy with duplicate
injections. However, triplicate injections provide a reasonable measure
of analytical precision without being overly burdensome. We do not feel
the increase in time and costs associated with the third injection will
significantly affect a typical test, considering the added benefits to
data quality that are gained.
Several commenters asked us to revise and clarify various aspects
of Section 10. We have made these modifications to address their
concerns.
Regarding Section 13.1, one commenter noted that Method 18 is not a
method in the general sense, but is more of a guideline on how to
develop and document a test method. The commenter therefore felt that
any prospective method should be written up and submitted to us along
with the proper documentation that includes recovery study results. We
disagree with this commenter. Method 18, which has been cited and used
for many years, is a specific gas chromatography method with specific
sampling, analytical, and data quality requirements. The method was
written to accomodate many test sites having many possible target
compounds and gas matrices. The tester has been given numerous
sampling, separation, and analytical system options to make the method
adaptable to the needs of various compliance demonstrations.
Several commenters asked us to clarify the 5 to 10 percent relative
standard deviation (RSD) requirement for calibration standards in
Section 13.1.
We have added clarity to Section 13.1. The 5 to 10 percent RSD is
not a precision criterion for calibration standards but a typical
precision range for analyzing field samples. Five percent RSD is
required for triplicate injections of calibration standards.
D. Method 25 (Part 60, Appendix A)
One commenter noted that Method 25 has limitations due to
conditions that may exist in stack gas. If such conditions exist, the
commenter recommends interfacing a nonmethane analyzer directly to the
source or use Method 25A or 25B to measure the emissions. The commenter
recommended modifying Method 25 to allow instruments that are able to
determine the methane and nonmethane portions using components
different from those described by Method 25 when the analyzer is
directly interfaced to the source. The commenter feels that Method 25
would be more practical for determining methane/nonmethane emissions at
the field site if the method could be modified to allow these other
analyzers. The commenter feels that it will also be necessary that
fixed performance specifications be defined in the method, such as
those for Method 6C. We believe these comments address method changes
that are beyond those covered in the proposal and are, therefore,
beyond the scope of this action. The commenter is encouraged to pursue
these method changes through other appropriate channels such as
submitting a request to use them as an alternative method.
E. Performance Specification 15 (Part 60, Appendix B)
One commenter noted that the statement of applicability for the
demonstration is limited to the criteria we gave. The commenter stated
that, with performance based measurement systems, the focus is on data
quality objectives (DQO) where the performance specifications are
coupled with the DQO. We believe the purpose of reference methods and,
in this case
[[Page 61747]]
performance specifications, is to provide standard procedures for
sources to follow in order to provide quality emission data. However,
we do provide latitude to sources by publishing performance-based
methods and PS whenever possible. This performance specification is one
such procedure; as long as an FTIR sampling system meets the
requirements of the performance specifications, it can be used for any
regulated pollutant.
Based on public comments and upon further deliberation, we have
removed the system calibration requirement from Section 10.3 of PS-15.
Since both a system calibration and the calibration transfer standard
measurement basically test instrument function, having both of these
requirements in the performance specifications is redundant.
One commenter felt that the number of runs should be given as
``guidance'' rather than made a requirement. We set the requirement for
nine runs (when comparing the FTIR to a reference method) and 10 runs
(when comparing the FTIR to a reference monitor) because these are
standard prodedures for performance specifications. We note that this
performance specification also allows analyte spiking as an option;
therefore, a revision on this point is not necessary.
One commenter noted that Section 11.1.1.4.3 states ``if the RM is a
CEM, synchronize the sampling flow rates of the RM and the FTIR CEM.''
The commenter noted that instrumental analyzers are currently used for
reference methods. EPA Methods 6C, 7E, 3A, and 10 measure
SO2, NOX, O2, CO2, and CO
on a continuous basis for a short period of time and are referred to as
instrumental analyzers and not CEMs. The commenter felt the statement
should read ``if the reference method is an instrumental analyzer,
synchronize the sampling flow rates of the RM and the FTIR.'' We agree
with the commenter and have made the noted change.
IV. What Revisions Were Made That Were Not in the Proposed Rule?
A revision was made to Section 6.6 of Method 21 of Part 60 to
clarify the VOC monitoring instrument specifications. The requirement
for the instrument to be intrinsically safe for Classes 1 and 2,
Division 1 conditions has been amended to require them to be
intrinsically safe for Class 1 and/or Class 2, Division 1 conditions,
as appropriate. The performance test provisions of Sec. 60.754(d) for
determining control device efficiency when combusting landfill gas were
amended to allow the use of Method 25 as an alternative to Methods 18
and 25C. The tester has the option of using either Method 18, 25, or
25C in this case. These amendments were not published in the proposed
rule.
V. Administrative Requirements
A. Docket
Docket A-97-12 is an organized and complete file of all information
submitted to us or otherwise considered in the development of this
final rulemaking. The principal purposes of the docket are: (1) to
allow interested parties to identify and locate documents so that they
can effectively participate in the rulemaking process, and (2) to serve
as the record in case of judicial review (except for interagency review
materials) [Clean Air Act Section 307(d)(7)(A), 42 U.S.C.
7607(d)(7)(A)].
B. Office of Management and Budget Review
Under Executive Order 12866 (58 FR 51735 October 4, 1993), we must
determine whether the regulatory action is ``significant'' and
therefore subject to Office of Management and Budget (OMB) review and
the requirements of this Executive Order. The Order defines
``significant regulatory action'' as one that is likely to result in a
rule that may: (1) Have an annual effect on the economy of $100 million
or more or adversely affect in a material way the economy, a sector of
the economy, productivity, competition, jobs, the environment, public
health or safety, or State, Local, or Tribal governments or
communities; (2) Create a serious inconsistency or otherwise interfere
with an action taken or planned by another agency; (3) Materially alter
the budgetary impact of entitlements, grants, user fees, or loan
programs, or the rights and obligations of recipients thereof; or (4)
Raise novel legal or policy issues arising out of legal mandates, the
President's priorities, or the principles set forth in the Executive
Order.
We have determined that this rule is not a ``significant regulatory
action'' under the terms of Executive Order 12866 and is therefore not
subject to OMB review. We have determined that this regulation would
result in none of the economic effects set forth in Section 1 of the
Order because it does not impose emission measurement requirements
beyond those specified in the current regulations, nor does it change
any emission standard.
C. Regulatory Flexibility Act Compliance
We have determined that it is not necessary to prepare a regulatory
flexibility analysis in connection with this final rule. We have also
determined that this rule will not have a significant economic impact
on a substantial number of small businesses. This rulemaking does not
impose emission measurement requirements beyond those specified in the
current regulations, nor does it change any emission standard.
D. Paperwork Reduction Act
This rule does not impose or change any information collection
requirements. The Paperwork Reduction Act of 1980, 44 U.S.C. 3501, et
seq., is not required.
E. Unfunded Mandates Reform Act
Title II of the unfunded Mandates Reform Act of 1995 (UMRA), Pub.
L. 104-4, establishes requirements for Federal agencies to assess the
effects of their regulatory action on State, local, and tribal
governments and the private sector. Under section 202 of the UMRA, we
generally must prepare a written statement, including a cost-benefit
analysis, for proposed and final rules with ``Federal mandates'' that
may result in expenditures by State, local, and tribal governments, in
the aggregate, or by the private sector, of $100 million or more in any
one year. Before promulgating an EPA rule for which a written statement
is needed, Section 205 of the UMRA generally requires us to identify
and consider a reasonable number of regulatory alternatives and adopt
the least costly, most cost-effective or least burdensome alternative
that achieves the objectives of the rule. The provisions of Section 205
do not apply when they are inconsistent with applicable law. Moreover,
Section 205 allows EPA to adopt an alternative other than the least
costly, most cost-effective or least burdensome alternative if the
Administrator publishes with the final rule an explanation why that
alternative was not adopted. Before we establish any regulatory
requirement that may significantly or uniquely affect small
governments, including tribal governments, we must develop a small
government agency plan as required under Section 203 of the UMRA. The
plan must provide for notifying potentially affected small governments,
enabling officials of affected small governments to have meaningful and
timely input in the development of our regulatory proposals with
significant Federal intergovernmental mandates, and informing,
educating, and advising small governments on compliance with the
regulatory requirements.
Today's rule contains no Federal mandates (under the regulatory
[[Page 61748]]
provisions of Title II of the UMRA) for State, local, or tribal
governments or the private sector. We have determined that today's rule
does not include a Federal mandate because it imposes no enforceable
duty on any State, local, and tribal governments, or the private
sector. Today's rule simply makes corrections and minor revisions to
current testing requirements and promulgates a monitoring specification
that can be used to support future monitoring rules. For the same
reason we have also determined that this rule contains no regulatory
requirements that might significantly or uniquely affect small
governments.
F. Executive Order 13132 (Federalism)
Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August
10, 1999), requires EPA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' is defined in the
Executive Order to include regulations that 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.'' Under
Executive Order 13132, EPA may not issue a regulation that has
federalism implications, that imposes substantial direct compliance
costs, and that is not required by statute, unless the Federal
government provides the funds necessary to pay the direct compliance
costs incurred by State and local governments, or EPA consults with
State and local officials early in the process of developing the
proposed regulation. EPA also may not issue a regulation that has
federalism implications and that preempts State law unless the Agency
consults with State and local officials early in the process of
developing the proposed regulation.
If EPA complies by consulting, Executive Order 13132 requires EPA
to provide to the Office of Management and Budget (OMB), in a
separately identified section of the preamble to the rule, a federalism
summary impact statement (FSIS). The FSIS must include a description of
the extent of EPA's prior consultation with State and local officials,
a summary of the nature of their concerns and the agency's position
supporting the need to issue the regulation, and a statement of the
extent to which the concerns of State and local officials have been
met. Also, when EPA transmits a draft final rule with federalism
implications to OMB for review pursuant to Executive Order 12866, EPA
must include a certification from the agency's Federalism Official
stating that EPA has met the requirements of Executive Order 13132 in a
meaningful and timely manner.
This final rule 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, as specified in Executive Order 13132.
This final rule simply makes corrections and minor revisions to current
testing requirements and promulgates a monitoring specification that
can be used to support future monitoring rules. Thus, the requirements
of section 6 of the Executive Order do not apply to this rule.
G. Executive Order 13084: Consultation and Coordination With Indian
Tribal Governments
Under Executive Order 13084, we may not issue a regulation that is
not required by statute, that significantly or uniquely affects the
communities of Indian tribal governments, and that imposes substantial
direct compliance costs on those communities, unless the Federal
government provides the funds necessary to pay the direct compliance
costs incurred by the tribal governments, or we consult with those
governments. If we comply by consulting, Executive Order 13094 requires
us to provide to the Office of Management and Budget, in a separately
identified section of the preamble to the rule, a description of the
extent of our prior consultation with representatives of affected
tribal governments, a summary of the nature of their concerns, and a
statement supporting the need to issue the regulation. In addition,
Executive Order 13084 requires us to develop an effective process
permitting elected and other representatives of Indian tribal
governments ``to provide meaningful and timely input in the development
of regulatory policies on matters that significantly or uniquely affect
their communities.'' Today's rule does not significantly or uniquely
affect the communities of Indian tribal governments. This rule only
amends regulatory requirements that are already in effect and adds no
additional requirements. Accordingly, the requirements of Section 3(b)
of Executive Order 13084 do not apply to this rule.
H. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
Executive Order 13045: ``Protection of Children from Environmental
Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997) applies
to any rule that: (1) Is determined to be ``economically significant''
as defined under E.O. 12866, and (2) concerns an environmental health
or safety risk that we have reason to believe may have a
disproportionate effect on children. If the regulatory action meets
both criteria, we must evaluate the environmental health or safety
effects of the planned rule on children, and explain why the planned
regulation is preferable to other potentially effective and reasonably
feasible alternatives we considered.
We interpret E.O. 13045 as applying only to those regulatory
actions that are based on health or safety risks, such that the
analysis required under section 5-501 of the Order has the potential to
influence the regulation. This rule is not subject to E.O. 13045
because it does not establish an environmental standard intended to
mitigate health or safety risks.
I. Submission to Congress and the General Accounting Office
The Congressional Review Act, 5 U.S.C. 801, et seq., as added by
the Small Business Regulatory Enforcement Fairness Act of 1996,
generally provides that before a rule may take effect, the agency
promulgating the rule must submit a rule report, which includes a copy
of the rule, to each House of the Congress and to the Comptroller
General of the United States. We will submit a report containing this
rule and other required information to the U.S. Senate, the U.S. House
of Representatives, and the Comptroller General of the United States
before it is published in the Federal Register. This action is not a
``major rule'' as defined by 5 U.S.C. 804(2). This rule will be
effective October 17, 2000.
J. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), P.L. 104-113 (15 U.S.C. 272), directs us to use
voluntary consensus standards (VCSs) in our regulatory activities
unless to do so would be inconsistent with applicable law or otherwise
impractical. Voluntary consensus standards are technical standards
(e.g., materials specifications, test methods, sampling procedures,
business practices, etc.) that are developed or adopted by VCS bodies.
[[Page 61749]]
The NTTAA requires us to provide Congress, through OMB, explanations
when we decide not to use available and applicable VCSs.
This rulemaking involves technical standards. Specifically, this
rule makes technical corrections to portions of the subparts in Parts
60, 61, and 63 pertaining to source testing or monitoring of emissions
and operations. The rule does not, however, change the nature of any of
the technical standards currently in use. Moreover, many of the
technical standards currently in use are VCSs developed by the American
Society for Testing and Materials (ASTM). In fact, we have taken the
opportunity presented by this rulemaking to update the references to
the ASTM standards to include the dates of the most recent versions of
these standards (see Section III.A. of the preamble for a full
discussion). A complete list of the ASTM standards updated by this rule
can be found in Part 60.17. Thus, today's action is consistent with our
obligation to use VCSs in our regulatory activities whenever
practicable.
Finally, we are promulgating PS-15, which identifies certification
criteria for continuous emission monitoring systems (CEMS) using
fourier transform infrared spectroscopy (FTIR). PS-15 is a performance
specification that is being issued as an example procedure for use by
industry and regulatory agencies as appropriate. While there are no
underlying national EPA standards that will require the use of this
procedure at this time, we conducted a search for VCS FTIR performance
specifications and found none. We plan to periodically conduct
rulemaking to make minor updates to test methods and performance
specifications. In these rulemakings, we will review updates to VCS
incorporated by reference and consider VCSs that may be used in lieu of
EPA reference methods. We plan to provide the opportunity for public
comment during these update rulemakings in part to allow VCS
organizations to suggest where VCSs may be available for our use.
K. Plain Language in Government Writing
This rule is not written in the plain language format. In most
cases, the rule corrects errors and makes updates to small portions of
existing regulations that are not in plain language. The new plain
language format was not used to keep the language of the amended
sections consistent with that of the unamended rules. Also, the test
methods were reformatted and proposed before the plain language
provisions were mandated. Due to their volume, the time and costs
associated with the magnitude of effort required to rewrite the final
methods in plain language is prohibitive. However, this preamble is
written in plain language, and we believe the amendments and
reformatted test methods have been written clearly.

7602.
Sec. 60.11 [Amended]
2. Amend Sec. 60.11 by:
a. In paragraphs (b) and (e)(1), by revising the words ``Reference
Method 9'' to read ``Method 9'' wherever they occur;
b. In paragraph (e)(5), revise the words ``to determine opacity
compliance'' in the last sentence to read ``to determine compliance
with the opacity standard.''
Sec. 60.13 [Amended]
3. Amend Sec. 60.13 by:
a. Revising the last two sentences in paragraph (d)(1), revising
paragraph (g), and revising the first sentence in paragraph (j)(2).
b. Revising the words ``ng/J of pollutant'' to read ``ng of
pollutant per J of heat input'' in the sixth sentence of paragraph (h).
c. Revising the words ``with the effluent gases'' to read ``in the
effluent gases'' in paragraph (i)(1).
d. Revising the words ``effluent from two or more affected
facilities are released'' to read ``effluent from two or more affected
facilities is released'' in paragraph (i)(9).
e. Revising the words ``relative accuracy test'' to read ``relative
accuracy (RA) test'' in the paragraph (j) introductory text.
f. Revising the words ``relative accuracy'' to read ``RA'' in
paragraphs (j)(1) and (2).
g. Revising the section references ``section 7'' and ``section 10''

The revisions read as follows:
Sec. 60.13 Monitoring requirements.
* * * * *
(d) * * *
(1) * * * For continuous monitoring systems measuring opacity of
emissions not using automatic zero adjustments, the optical surfaces
exposed to the effluent gases shall be cleaned prior to performing the
zero and span drift adjustments. For systems using automatic zero
adjustments, the optical surfaces shall be cleaned when the cumulative
automatic zero compensation exceeds 4 percent opacity.
* * * * *
(g)(1) When more than one continuous monitoring system is used to
measure the emissions from only one affected facility (e.g., multiple
breechings, multiple outlets), the owner or operator shall report the
results as required from each continuous monitoring system. When the
effluent from one affected facility is released to the atmosphere
through more than one point, the owner or operator shall install an
applicable continuous monitoring system on each separate effluent
unless installation of fewer systems is approved by the Administrator.
(2) When the effluents from two or more affected facilities subject
to the same opacity standard are combined before being released to the
atmosphere, the owner or operator may either install a continuous
opacity monitoring system at a location monitoring the combined
effluent or install an opacity combiner system comprised of opacity and
flow monitoring systems on each stream, and shall report as per
Sec. 60.7(c) on the combined effluent. When the affected facilities are
not subject to the same opacity standard, the owner or operator shall
report the results as per Sec. 60.7(c) on the combined effluent against
the most stringent opacity standard
[[Page 61750]]
applicable, except for documented periods of shutdown of the affected
facility, subject to the most stringent opacity standard. During such
times, the next most stringent opacity standard shall apply.
(3) When the effluents from two or more affected facilities subject
to the same emissions standard, other than opacity, are combined before
being released to the atmosphere, the owner or operator may install
applicable continuous emission monitoring systems on each effluent or
on the combined effluent. The owner or operator may report the results
as required for each affected facility or for the combined effluent.
When the affected facilities are not subject to the same emissions
standard, separate continuous emission monitoring systems shall be
installed on each effluent and the owner or operator shall report as
required for each affected facility.
* * * * *
(j) * * *
(2) The waiver of a CEMS RA test will be reviewed and may be
rescinded at such time, following successful completion of the
alternative RA procedure, that the CEMS data indicate that the source
emissions are approaching the level. * * *
* * * * *
Sec. 60.14 [Amended]

if the cross-sectional area is less than 5.00 m2 (53.8
ft2) or at a point no closer to the walls than 1.00 m (39.4
in.) if the cross-sectional area is 5.00 m2 or more and the
centroid is more than 1 m from the wall. The sampling time and sample
volume shall be at least 10 minutes and 0.010 dscm (0.35 dscf) for each

Sec. 60.754 Test methods and procedures.
(a) * * *
(3) Tier 2. The landfill owner or operator shall determine the NMOC
concentration using the following sampling procedure. The landfill
owner or operator shall install at least two sample probes per hectare
of landfill surface that has retained waste for at least 2 years. If
the landfill is larger than 25 hectares in area, only 50 samples are
required. The sample probes should be located to avoid known areas of
nondegradable solid waste. The owner or operator shall collect and
analyze one sample of landfill gas from each probe to determine the
NMOC concentration using Method 25 or 25C of Appendix A of this part.
Method 18 of Appendix A of this part may be used to analyze the samples
collected by the Method 25 or 25C sampling procedure. Taking composite
samples from different probes into a single cylinder is allowed;
however, equal sample volumes must be taken from each probe. For each
composite, the sampling rate, collection times, beginning and ending
cylinder vacuums, or alternative volume measurements must be recorded
to verify that composite volumes are equal. Composite sample volumes
should not be less than one liter unless evidence can be provided to
substantiate the accuracy of smaller volumes. Terminate compositing
before the cylinder approaches ambient pressure where measurement
accuracy diminishes. If using Method 18, the owner or operator must
identify all compounds in the sample and, as a minimum, test for those
compounds published in the most recent Compilation of Air Pollutant
Emission Factors (AP-42), minus carbon monoxide, hydrogen sulfide, and
mercury. As a minimum, the instrument must be calibrated for each of
the compounds on the list. Convert the concentration of each Method 18
compound to CNMOC as hexane by multiplying by the ratio of
its carbon atoms divided by six. If more than the required number of
samples are taken, all samples must be used in the analysis. The
landfill owner or operator must divide the NMOC concentration from
Method 25 or 25C of Appendix A of this part by six to convert from
CNMOC as carbon to CNMOC as hexane. If the
landfill has an active or passive gas removal system in place, Method
25 or 25C samples may be collected from these systems instead of
surface probes provided the removal system can be shown to provide
sampling as representative as the two sampling probe per hectare
requirement. For active collection systems, samples may be collected
from the common header pipe before the gas moving or condensate removal
equipment. For these systems, a minimum of three samples must be
collected from the header pipe.
* * * * *
(d) For the performance test required in Sec. 60.752(b)(2)(iii)(B),
Method 25, 25C, or Method 18 of Appendix A of this part must be used to
determine compliance with the 98 weight-percent efficiency or the 20
ppmv outlet concentration level, unless another method to demonstrate
compliance has been approved by the Administrator as provided by
Sec. 60.752(b)(2)(i)(B). Method 3 or 3A shall be used to determine
oxygen for correcting the NMOC concentration as hexane to 3 percent. In
cases where the outlet concentration is less than 50 ppm NMOC as carbon
(8 ppm NMOC as hexane), Method 25A should be used in place of Method
25. * * *

METHOD 1--Sample and Velocity Traverses for Stationary Sources
Note: This method does not include all of the specifications
(e.g., equipment and supplies) and procedures (e.g., sampling)
essential to its performance. Some material is incorporated by
reference from other methods in this part. Therefore, to obtain
reliable results, persons using this method should have a thorough
knowledge of at least the following additional test method: Method
2.
1.0 Scope and Application
1.1 Measured Parameters. The purpose of the method is to provide
guidance for the selection of sampling ports and traverse points at
which sampling for air pollutants will be performed pursuant to
regulations set forth in this part. Two procedures are presented: a
simplified procedure, and an alternative procedure (see Section 11.5).
The magnitude of cyclonic flow of effluent gas in a stack or duct is
the only parameter quantitatively measured in the simplified procedure.
1.2 Applicability. This method is applicable to gas streams
flowing in ducts, stacks, and flues. This method cannot be used when:
(1) the flow is cyclonic or swirling; or (2) a stack is smaller than
0.30 meter (12 in.) in diameter, or 0.071 m\2\ (113 in.\2\) in cross-
sectional area. The simplified procedure cannot be used when the
measurement site is less than two stack or duct diameters downstream or
less than a half diameter upstream from a flow disturbance.
1.3 Data Quality Objectives. Adherence to the requirements of this
method will enhance the quality of the data obtained from air pollutant
sampling methods.
Note: The requirements of this method must be considered before
construction of a new facility from which emissions are to be
measured; failure to do so may require subsequent alterations to the
stack or deviation from the standard procedure. Cases involving
variants are subject to approval by the Administrator.
2.0 Summary of Method
2.1 This method is designed to aid in the representative
measurement of pollutant emissions and/or total volumetric flow rate
from a stationary source. A measurement site where the effluent stream
is flowing in a known direction is selected, and the cross-section of
the stack is divided into a number of equal areas. Traverse points are
then located within each of these equal areas.
3.0 Definitions [Reserved]
4.0 Interferences [Reserved]
5.0 Safety
5.1 Disclaimer. This method may involve hazardous materials,
operations, and equipment. This test method may not address all of the
safety problems associated with its use. It is the responsibility of
the user of this test method to establish appropriate safety and health
practices and determine the applicability of regulatory limitations
prior to performing this test method.
6.0 Equipment and Supplies.
6.1 Apparatus. The apparatus described below is required only when
utilizing the alternative site selection procedure described in Section
11.5 of this method.
6.1.1 Directional Probe. Any directional probe, such as United
Sensor Type DA Three-Dimensional Directional Probe, capable of
measuring both the pitch and yaw angles of gas flows is acceptable.
Before using the probe, assign an identification number to the
directional probe, and permanently mark or engrave the number on the
body of the probe. The pressure holes of directional probes are
susceptible to
[[Page 61780]]
plugging when used in particulate-laden gas streams. Therefore, a
procedure for cleaning the pressure holes by ``back-purging'' with
pressurized air is required.
6.1.2 Differential Pressure Gauges. Inclined manometers, U-tube
manometers, or other differential pressure gauges (e.g., magnehelic
gauges) that meet the specifications described in Method 2, Section
6.2.
Note: If the differential pressure gauge produces both negative
and positive readings, then both negative and positive pressure
readings shall be calibrated at a minimum of three points as
specified in Method 2, Section 6.2.
7.0 Reagents and Standards [Reserved]
8.0 Sample Collection, Preservation, Storage, and Transport [Reserved]
9.0 Quality Control [Reserved]
10.0 Calibration and Standardization [Reserved]
11.0 Procedure
11.1 Selection of Measurement Site.
11.1.1 Sampling and/or velocity measurements are performed at a
site located at least eight stack or duct diameters downstream and two
diameters upstream from any flow disturbance such as a bend, expansion,
or contraction in the stack, or from a visible flame. If necessary, an
alternative location may be selected, at a position at least two stack
or duct diameters downstream and a half diameter upstream from any flow
disturbance.
11.1.2 An alternative procedure is available for determining the
acceptability of a measurement location not meeting the criteria above.
This procedure described in Section 11.5 allows for the determination
of gas flow angles at the sampling points and comparison of the
measured results with acceptability criteria.
11.2 Determining the Number of Traverse Points.
11.2.1 Particulate Traverses.
11.2.1.1 When the eight- and two-diameter criterion can be met,
the minimum number of traverse points shall be: (1) twelve, for
circular or rectangular stacks with diameters (or equivalent diameters)
greater than 0.61 meter (24 in.); (2) eight, for circular stacks with
diameters between 0.30 and 0.61 meter (12 and 24 in.); and (3) nine,
for rectangular stacks with equivalent diameters between 0.30 and 0.61
meter (12 and 24 in.).
11.2.1.2 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. Then, determine from Figure 1-1 the minimum number
of traverse points that corresponds: (1) to the number of duct
diameters upstream; and (2) to the number of diameters downstream.
Select the higher of the two minimum numbers of traverse points, or a
greater value, so that for circular stacks the number is a multiple of
4, and for rectangular stacks, the number is one of those shown in
Table 1-1.
11.2.2 Velocity (Non-Particulate) Traverses. When velocity or
volumetric flow rate is to be determined (but not particulate matter),
the same procedure as that used for particulate traverses (Section
11.2.1) is followed, except that Figure 1-2 may be used instead of
Figure 1-1.
11.3 Cross-Sectional Layout and Location of Traverse Points.
11.3.1 Circular Stacks.
11.3.1.1 Locate the traverse points on two perpendicular diameters
according to Table 1-2 and the example shown in Figure 1-3. Any
equation (see examples in References 2 and 3 in Section 16.0) that
gives the same values as those in Table 1-2 may be used in lieu of
Table 1-2.
11.3.1.2 For particulate traverses, one of the diameters must
coincide with the plane containing the greatest expected concentration
variation (e.g., after bends); one diameter shall be congruent to the
direction of the bend. This requirement becomes less critical as the
distance from the disturbance increases; therefore, other diameter
locations may be used, subject to the approval of the Administrator.
11.3.1.3 In addition, for elliptical stacks having unequal
perpendicular diameters, separate traverse points shall be calculated
and located along each diameter. To determine the cross-sectional area
of the elliptical stack, use the following equation:
Square Area = D1 x D2 x 0.7854
Where: D1 = Stack diameter 1
D2 = Stack diameter 2
11.3.1.4 In addition, for stacks having diameters greater than
0.61 m (24 in.), no traverse points shall be within 2.5 centimeters
(1.00 in.) of the stack walls; and for stack diameters equal to or less
than 0.61 m (24 in.), no traverse points shall be located within 1.3 cm
(0.50 in.) of the stack walls. To meet these criteria, observe the
procedures given below.
11.3.2 Stacks With Diameters Greater Than 0.61 m (24 in.).
11.3.2.1 When any of the traverse points as located in Section
11.3.1 fall within 2.5 cm (1.0 in.) of the stack walls, relocate them
away from the stack walls to: (1) a distance of 2.5 cm (1.0 in.); or
(2) a distance equal to the nozzle inside diameter, whichever is
larger. These relocated traverse points (on each end of a diameter)
shall be the ``adjusted'' traverse points.
11.3.2.2 Whenever two successive traverse points are combined to
form a single adjusted traverse point, treat the adjusted point as two
separate traverse points, both in the sampling and/or velocity
measurement procedure, and in recording of the data.
11.3.3 Stacks With Diameters Equal To or Less Than 0.61 m (24
in.). Follow the procedure in Section 11.3.1.1, noting only that any
``adjusted'' points should be relocated away from the stack walls to:
(1) a distance of 1.3 cm (0.50 in.); or (2) a distance equal to the
nozzle inside diameter, whichever is larger.
11.3.4 Rectangular Stacks.
11.3.4.1 Determine the number of traverse points as explained in
Sections 11.1 and 11.2 of this method. From Table 1-1, determine the
grid configuration. Divide the stack cross-section into as many equal
rectangular elemental areas as traverse points, and then locate a
traverse point at the centroid of each equal area according to the
example in Figure 1-4.
11.3.4.2 To use more than the minimum number of traverse points,
expand the ``minimum number of traverse points'' matrix (see Table 1-1)
by adding the extra traverse points along one or the other or both legs
of the matrix; the final matrix need not be balanced. For example, if a
4 x 3 ``minimum number of points'' matrix were expanded to 36 points,
the final matrix could be 9 x 4 or 12 x 3, and would not
necessarily have to be 6 x 6. After constructing the final matrix,
divide the stack cross-section into as many equal rectangular,
elemental areas as traverse points, and locate a traverse point at the
centroid of each equal area.
11.3.4.3 The situation of traverse points being too close to the
stack walls is not expected to arise with rectangular stacks. If this
problem should ever arise, the Administrator must be contacted for
resolution of the matter.
11.4 Verification of Absence of Cyclonic Flow.
11.4.1 In most stationary sources, the direction of stack gas flow
is essentially parallel to the stack walls. However, cyclonic flow may
exist (1) after such devices as cyclones and inertial demisters
following venturi
[[Page 61781]]
scrubbers, or (2) in stacks having tangential inlets or other duct
configurations which tend to induce swirling; in these instances, the
presence or absence of cyclonic flow at the sampling location must be
determined. The following techniques are acceptable for this
determination.
11.4.2 Level and zero the manometer. Connect a Type S pitot tube
to the manometer and leak-check system. Position the Type S pitot tube
at each traverse point, in succession, so that the planes of the face
openings of the pitot tube are perpendicular to the stack cross-
sectional plane; when the Type S pitot tube is in this position, it is
at ``0 deg. reference.'' Note the differential pressure (p)
reading at each traverse point. If a null (zero) pitot reading is
obtained at 0 deg. reference at a given traverse point, an acceptable
flow condition exists at that point. If the pitot reading is not zero
at 0 deg. reference, rotate the pitot tube (up to 90 deg.
yaw angle), until a null reading is obtained. Carefully determine and
record the value of the rotation angle () to the nearest
degree. After the null technique has been applied at each traverse
point, calculate the average of the absolute values of ;
assign values of 0 deg. to those points for which no rotation
was required, and include these in the overall average. If the average
value of is greater than 20 deg., the overall flow condition
in the stack is unacceptable, and alternative methodology, subject to
the approval of the Administrator, must be used to perform accurate
sample and velocity traverses.
11.5 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 Alternative Measurement Site Selection Procedure. This
alternative 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 in. 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 for the location and layout of the traverse points. If
the measurement location is determined to be acceptable according to
the criteria in this alternative procedure, use the same traverse point
number and locations for sampling and velocity measurements.
11.5.3 Measurement Procedure.
11.5.3.1 Prepare the directional probe and differential pressure
gauges as recommended by the manufacturer. Capillary tubing or surge
tanks may be used to dampen pressure fluctuations. It is recommended,
but not required, that a pretest leak check be conducted. To perform a
leak check, pressurize or use suction on the impact opening until a
reading of at least 7.6 cm (3 in.) H2O registers on the
differential pressure gauge, then plug the impact opening. The pressure
of a leak-free system will remain stable for at least 15 seconds.
11.5.3.2 Level and zero the manometers. Since the manometer level
and zero may drift because of vibrations and temperature changes,
periodically check the level and zero during the traverse.
11.5.3.3 Position the probe at the appropriate locations in the
gas stream, and rotate until zero deflection is indicated for the yaw
angle pressure gauge. Determine and record the yaw angle. Record the
pressure gauge readings for the pitch angle, and determine the pitch
angle from the calibration curve. Repeat this procedure for each
traverse point. Complete a ``back-purge'' of the pressure lines and the
impact openings prior to measurements of each traverse point.
11.5.3.4 A post-test check as described in Section 11.5.3.1 is
required. If the criteria for a leak-free system are not met, repair
the equipment, and repeat the flow angle measurements.
11.5.4 Calibration. Use a flow system as described in Sections
10.1.2.1 and 10.1.2.2 of Method 2. In addition, the flow system shall
have the capacity to generate two test-section velocities: one between
365 and 730 m/min (1,200 and 2,400 ft/min) and one between 730 and
1,100 m/min (2,400 and 3,600 ft/min).
11.5.4.1 Cut two entry ports in the test section. The axes through
the entry ports shall be perpendicular to each other and intersect in
the centroid of the test section. The ports should be elongated slots
parallel to the axis of the test section and of sufficient length to
allow measurement of pitch angles while maintaining the pitot head
position at the test-section centroid. To facilitate alignment of the
directional probe during calibration, the test section should be
constructed of plexiglass or some other transparent material. All
calibration measurements should be made at the same point in the test
section, preferably at the centroid of the test section.
11.5.4.2 To ensure that the gas flow is parallel to the central
axis of the test section, follow the procedure outlined in Section 11.4
for cyclonic flow determination to measure the gas flow angles at the
centroid of the test section from two test ports located 90 deg. apart.
The gas flow angle measured in each port must be 2 deg. of
0 deg.. Straightening vanes should be installed, if necessary, to meet
this criterion.
11.5.4.3 Pitch Angle Calibration. Perform a calibration traverse
according to the manufacturer's recommended protocol in 5 deg.
increments for angles from -60 deg. to +60 deg. at one velocity in each
of the two ranges specified above. Average the pressure ratio values
obtained for each angle in the two flow ranges, and plot a calibration
curve with the average values of the pressure ratio (or other suitable
measurement factor as recommended by the manufacturer) versus the pitch
angle. Draw a smooth line through the data points. Plot also the data
values for each traverse point. Determine the differences between the
measured data values and the angle from the calibration curve at the
same pressure ratio. The difference at each comparison must be within
2 deg. for angles between 0 deg. and 40 deg. and within 3 deg. for
angles between 40 deg. and 60 deg..
11.5.4.4 Yaw Angle Calibration. Mark the three-dimensional probe
to allow the determination of the yaw position of the probe. This is
usually a line extending the length of the probe and aligned with the
impact opening. To determine the accuracy of measurements of the yaw
angle, only the zero or null position need be calibrated as follows:
Place the directional probe in the test section, and rotate the probe
until the zero position is found. With a protractor or other angle
measuring device, measure the angle indicated by the yaw angle
indicator on the three-dimensional probe. This should be within 2 deg.
of 0 deg.. Repeat this measurement for any other points along the
length of the pitot where yaw angle measurements could be read in order
to account for
[[Page 61782]]
variations in the pitot markings used to indicate pitot head positions.

11.5 of this method) is required, perform the following calculations

calculations retaining at least one extra significant figure beyond
that of the acquired data. Round the values after the final
calculations.

Method 1A--Sample and Velocity Traverses for Stationary Sources
With Small Stacks or Ducts
Note: This method does not include all of the specifications
(e.g., equipment and supplies) and procedures (e.g., sampling)
essential to its performance. Some material is incorporated by
reference from other methods in this part. Therefore, to obtain
reliable results, persons using this method should have a thorough
knowledge of at least the following additional test method: Method
1.
1.0 Scope and Application
1.1 Measured Parameters. The purpose of the method is to provide
guidance for the selection of sampling ports and traverse points at
which sampling for air pollutants will be performed pursuant to
regulations set forth in this part.
1.2 Applicability. The applicability and principle of this method
are identical to Method 1, except its applicability is limited to
stacks or ducts. This method is applicable to flowing gas streams in
ducts, stacks, and flues of less than about 0.30 meter (12 in.) in
diameter, or 0.071 m 2 (113 in.2) in cross-
sectional area, but equal to or greater than about 0.10 meter (4 in.)
in diameter, or 0.0081 m 2 (12.57 in.2) in cross-
sectional area. This method cannot be used when the flow is cyclonic or
swirling.
1.3 Data Quality Objectives. Adherence to the requirements of this
method will enhance the quality of the data obtained from air pollutant
sampling methods.
2.0 Summary of Method
2.1 The method is designed to aid in the representative
measurement of pollutant emissions and/or total volumetric flow rate
from a stationary source. A measurement site or a pair of measurement
sites where the effluent stream is flowing in a known direction is
(are) selected. The cross-section of the stack is divided into a number
of equal areas. Traverse points are then located within each of these
equal areas.
2.2 In these small diameter stacks or ducts, the conventional
Method 5 stack assembly (consisting of a Type S pitot tube attached to
a sampling probe, equipped with a nozzle and thermocouple) blocks a
significant portion of the cross-section of the duct and causes
inaccurate measurements. Therefore, for particulate matter (PM)
sampling in small stacks or ducts, the gas velocity is measured using a
standard pitot tube downstream of the actual emission sampling site.
The straight run of duct between the PM sampling and velocity
measurement sites allows the flow profile, temporarily disturbed by the
presence of the sampling probe, to redevelop and stabilize.

5.0 Safety
5.1 Disclaimer. This method may involve hazardous materials,
operations, and equipment. This test method may not address all of the
safety problems associated with its use. It is the responsibility of
the user of this test method to establish appropriate safety and health
practices and determine the applicability of regulatory limitations
prior to performing this test method.

7.0 Reagents and Standards [Reserved]
8.0 Sample Collection, Preservation, Storage, and Transport [Reserved]
9.0 Quality Control [Reserved]
10.0 Calibration and Standardization [Reserved]
11.0 Procedure
11.1 Selection of Measurement Site.
11.1.1 Particulate Measurements--Steady or Unsteady Flow. Select a
particulate measurement site located preferably at least eight
equivalent stack or duct diameters downstream and 10 equivalent
diameters upstream from any flow disturbances such as bends,
expansions, or contractions in the stack, or from a visible flame.
Next, locate the velocity measurement site eight equivalent diameters
downstream of the particulate measurement site (see Figure 1A-1). If
such locations are not available, select an alternative particulate
measurement location at least two equivalent stack or duct diameters
downstream and two and one-half diameters upstream from any flow
disturbance. Then, locate the velocity measurement site two equivalent
diameters downstream from the particulate measurement site. (See
Section 12.2 of Method 1 for calculating equivalent diameters for a
rectangular cross-section.)
11.1.2 PM Sampling (Steady Flow) or Velocity (Steady or Unsteady
Flow) Measurements. For PM sampling when the volumetric flow rate in a
duct is constant with respect to time, Section 11.1.1 of Method 1 may
be followed, with the PM sampling and velocity measurement performed at
one location. To demonstrate that the flow rate is constant (within 10
percent) when PM measurements are made, perform complete velocity
traverses before and after the PM sampling run, and calculate the
deviation of the flow rate derived after the PM sampling run from the
one derived before the PM sampling run. The PM sampling run is
acceptable if the deviation does not exceed 10 percent.
11.2 Determining the Number of Traverse Points.
11.2.1 Particulate Measurements (Steady or Unsteady Flow). Use
Figure 1-1 of Method 1 to determine the number of traverse points to
use at both the velocity measurement and PM sampling locations. Before
referring to the figure, however, determine the distances between both
the velocity measurement and PM sampling sites to the nearest upstream
and downstream disturbances. Then divide each distance by the stack
diameter or equivalent diameter to express the distances in terms of
the number of duct diameters. Then, determine the number of traverse
points from Figure 1-1 of Method 1 corresponding to each of these four
distances. Choose the highest of the four numbers of traverse points
(or a greater number) so that, for circular ducts the number is a
multiple of four; and for rectangular ducts, the number is one of those
shown in Table 1-1 of Method 1. When the optimum duct diameter location
criteria can be satisfied, the minimum number of traverse points
required is eight for circular ducts and nine for rectangular ducts.
11.2.2 PM Sampling (Steady Flow) or only Velocity (Non-
Particulate) Measurements. Use Figure 1-2 of Method 1 to determine
number of traverse points, following the same procedure used for PM
sampling as described in Section 11.2.1 of Method 1. When the optimum
duct diameter location criteria can be satisfied, the minimum number of
traverse points required is eight for circular ducts and nine for
rectangular ducts.

Method 2--Determination of Stack Gas Velocity and Volumetric Flow
Rate (Type S Pitot Tube)
Note: This method does not include all of the specifications
(e.g., equipment and supplies) and procedures (e.g., sampling)
essential to its performance. Some material is incorporated by
reference from other methods in this part. Therefore, to obtain
reliable results, persons using this method should have a thorough
knowledge of at
least the following additional test method:
Method 1.
1.0 Scope and Application.
1.1 This method is applicable for the determination of the average
velocity and the volumetric flow rate of a gas stream.
1.2 This method is not applicable at measurement sites that fail
to meet the criteria of Method 1, Section 11.1. Also, the method cannot
be used for direct measurement in cyclonic or swirling gas streams;
Section 11.4 of Method 1 shows how to determine cyclonic or swirling
flow conditions. When unacceptable conditions exist, alternative
procedures, subject to the approval of the Administrator, must be
employed to produce accurate flow rate determinations. Examples of such
alternative procedures are: (1) to install straightening vanes; (2) to
calculate the total volumetric flow rate stoichiometrically, or (3) to
move to another measurement site at which the flow is acceptable.
1.3 Data Quality Objectives. Adherence to the requirements of this
method will enhance the quality of the data obtained from air pollutant
sampling methods.
2.0 Summary of Method.
2.1 The average gas velocity in a stack is determined from the gas
density and from measurement of the average velocity head with a Type S

6.0 Equipment and Supplies
Specifications for the apparatus are given below. Any other
apparatus that has been demonstrated (subject to approval of the
Administrator) to be capable of meeting the specifications will be
considered acceptable.
6.1 Type S Pitot Tube.
6.1.1 Pitot tube made of metal tubing (e.g., stainless steel) as
shown in Figure 2-1. It is recommended that the external tubing
diameter (dimension Dt, Figure 2-2b) be between 0.48 and
0.95 cm (\3/16\ and \3/8\ inch). There shall be an equal distance from
the base of each leg of the pitot tube to its face-opening plane
(dimensions PA and PB, Figure 2-2b); it is
recommended that this distance be between 1.05 and 1.50 times the
external tubing diameter. The face openings of the pitot tube shall,
preferably, be aligned as shown in Figure 2-2; however, slight
misalignments of the openings are permissible (see Figure 2-3).
6.1.2 The Type S pitot tube shall have a known coefficient,
determined as outlined in Section 10.0. An identification number shall
be assigned to the pitot tube; this number shall be permanently marked
or engraved on the body of the tube. A standard pitot tube may be used
instead of a Type S, provided that it meets the specifications of
Sections 6.7 and 10.2. Note, however, that the static and impact
pressure holes of standard pitot tubes are susceptible to plugging in
particulate-laden gas streams. Therefore, whenever a standard pitot
tube is used to perform a traverse, adequate proof must be furnished
that the openings of the pitot tube have not plugged up during the
traverse period. This can be accomplished by comparing the velocity
head (p) measurement recorded at a selected traverse point
(readable p value) with a second p measurement
recorded after ``back purging'' with pressurized air to clean the
impact and static holes of the standard pitot tube. If the before and
[[Page 61790]]
after p measurements are within 5 percent, then the traverse
data are acceptable. Otherwise, the data should be rejected and the
traverse measurements redone. Note that the selected traverse point
should be one that demonstrates a readable p value. If ``back
purging'' at regular intervals is part of a routine procedure, then
comparative p measurements shall be conducted as above for the
last two traverse points that exhibit suitable p measurements.
6.2 Differential Pressure Gauge. An inclined manometer or
equivalent device. Most sampling trains are equipped with a 10 in.
(water column) inclined-vertical manometer, having 0.01 in.
H20 divisions on the 0 to 1 in. inclined scale, and 0.1 in.
H20 divisions on the 1 to 10 in. vertical scale. This type
of manometer (or other gauge of equivalent sensitivity) is satisfactory
for the measurement of p values as low as 1.27 mm (0.05 in.)
H20. However, a differential pressure gauge of greater
sensitivity shall be used (subject to the approval of the
Administrator), if any of the following is found to be true: (1) the
arithmetic average of all p readings at the traverse points in
the stack is less than 1.27 mm (0.05 in.) H20; (2) for
traverses of 12 or more points, more than 10 percent of the individual
p readings are below 1.27 mm (0.05 in.) H20; or (3)
for traverses of fewer than 12 points, more than one p reading
is below 1.27 mm (0.05 in.) H20. Reference 18 (see Section
17.0) describes commercially available instrumentation for the
measurement of low-range gas velocities.
6.2.1 As an alternative to criteria (1) through (3) above,
Equation 2-1 (Section 12.2) may be used to determine the necessity of
using a more sensitive differential pressure gauge. If T is greater
than 1.05, the velocity head data are unacceptable and a more sensitive
differential pressure gauge must be used.
Note: If differential pressure gauges other than inclined
manometers are used (e.g., magnehelic gauges), their calibration
must be checked after each test series. To check the calibration of
a differential pressure gauge, compare p readings of the
gauge with those of a gauge-oil manometer at a minimum of three
points, approximately representing the range of p values in
the stack. If, at each point, the values of p as read by
the differential pressure gauge and gauge-oil manometer agree to
within 5 percent, the differential pressure gauge shall be
considered to be in proper calibration. Otherwise, the test series
shall either be voided, or procedures to adjust the measured
p values and final results shall be used, subject to the
approval of the Administrator.
6.3 Temperature Sensor. A thermocouple, liquid-filled bulb
thermometer, bimetallic thermometer, mercury-in-glass thermometer, or
other gauge capable of measuring temperatures to within 1.5 percent of
the minimum absolute stack temperature. The temperature sensor shall be
attached to the pitot tube such that the sensor tip does not touch any
metal; the gauge shall be in an interference-free arrangement with
respect to the pitot tube face openings (see Figure 2-1 and Figure 2-
4). Alternative positions may be used if the pitot tube-temperature
gauge system is calibrated according to the procedure of Section 10.0.
Provided that a difference of not more than 1 percent in the average
velocity measurement is introduced, the temperature gauge need not be
attached to the pitot tube. This alternative is subject to the approval
of the Administrator.
6.4 Pressure Probe and Gauge. A piezometer tube and mercury- or
water-filled U-tube manometer capable of measuring stack pressure to
within 2.5 mm (0.1 in.) Hg. The static tap of a standard type pitot
tube or one leg of a Type S pitot tube with the face opening planes
positioned parallel to the gas flow may also be used as the pressure
probe.
6.5 Barometer. A mercury, aneroid, or other barometer capable of
measuring atmospheric pressure to within 2.54 mm (0.1 in.) Hg.
Note: The barometric pressure reading may be obtained from a
nearby National Weather Service station. In this case, the station
value (which is the absolute barometric pressure) shall be requested
and an adjustment for elevation differences between the weather
station and sampling point shall be made at a rate of minus 2.5 mm
(0.1 in.) Hg per 30 m (100 ft) elevation increase or plus 2.5 mm
(0.1 in.) Hg per 30 m (100 ft.) for elevation decrease.
6.6 Gas Density Determination Equipment. Method 3 equipment, if
needed (see Section 8.6), to determine the stack gas dry molecular
weight, and Method 4 (reference method) or Method 5 equipment for
moisture content determination. Other methods may be used subject to
approval of the Administrator.
6.7 Calibration Pitot Tube. When calibration of the Type S pitot
tube is necessary (see Section 10.1), a standard pitot tube shall be
used for a reference. The standard pitot tube shall, preferably, have a
known coefficient, obtained either (1) directly from the National
Institute of Standards and Technology (NIST), Gaithersburg MD 20899,
(301) 975-2002, or (2) by calibration against another standard pitot
tube with an NIST-traceable coefficient. Alternatively, a standard
pitot tube designed according to the criteria given in Sections 6.7.1
through 6.7.5 below and illustrated in Figure 2-5 (see also References
7, 8, and 17 in Section 17.0) may be used. Pitot tubes designed
according to these specifications will have baseline coefficients of
0.99 0.01.
6.7.1 Standard Pitot Design.
6.7.1.1 Hemispherical (shown in Figure 2-5), ellipsoidal, or
conical tip.
6.7.1.2 A minimum of six diameters straight run (based upon D, the
external diameter of the tube) between the tip and the static pressure
holes.
6.7.1.3 A minimum of eight diameters straight run between the
static pressure holes and the centerline of the external tube,
following the 90 deg. bend.
6.7.1.4 Static pressure holes of equal size (approximately 0.1 D),
equally spaced in a piezometer ring configuration.
6.7.1.5 90 deg. bend, with curved or mitered junction.
6.8 Differential Pressure Gauge for Type S Pitot Tube Calibration.
An inclined manometer or equivalent. If the single-velocity calibration
technique is employed (see Section 10.1.2.3), the calibration
differential pressure gauge shall be readable to the nearest 0.127 mm
(0.005 in.) H20. For multivelocity calibrations, the gauge
shall be readable to the nearest 0.127 mm (0.005 in.) H20
for p values between 1.27 and 25.4 mm (0.05 and 1.00 in.)
H20, and to the nearest 1.27 mm (0.05 in.) H20
for p values above 25.4 mm (1.00 in.) H20. A
special, more sensitive gauge will be required to read p
values below 1.27 mm (0.05 in.) H20 (see Reference 18 in
Section 16.0).
7.0 Reagents and Standards [Reserved]
8.0 Sample Collection and Analysis
8.1 Set up the apparatus as shown in Figure 2-1. Capillary tubing
or surge tanks installed between the manometer and pitot tube may be
used to dampen p fluctuations. It is recommended, but not
required, that a pretest leak-check be conducted as follows: (1) blow
through the pitot impact opening until at least 7.6 cm (3.0 in.)
H20 velocity head registers on the manometer; then, close
off the impact opening. The pressure shall remain stable for at least
15 seconds; (2) do the same for the static pressure side, except using
suction to obtain the minimum of 7.6 cm (3.0 in.) H20. Other
leak-check procedures, subject to the approval of the Administrator,
may be used.
8.2 Level and zero the manometer. Because the manometer level and
zero
[[Page 61791]]
may drift due to vibrations and temperature changes, make periodic
checks during the traverse (at least once per hour). Record all
necessary data on a form similar to that shown in Figure 2-6.
8.3 Measure the velocity head and temperature at the traverse
points specified by Method 1. Ensure that the proper differential
pressure gauge is being used for the range of p values
encountered (see Section 6.2). If it is necessary to change to a more
sensitive gauge, do so, and remeasure the p and temperature
readings at each traverse point. Conduct a post-test leak-check
(mandatory), as described in Section 8.1 above, to validate the
traverse run.
8.4 Measure the static pressure in the stack. One reading is
usually adequate.
8.5 Determine the atmospheric pressure.
8.6 Determine the stack gas dry molecular weight. For combustion
processes or processes that emit essentially CO2,
O2, CO, and N2, use Method 3. For processes
emitting essentially air, an analysis need not be conducted; use a dry
molecular weight of 29.0. For other processes, other methods, subject
to the approval of the Administrator, must be used.
8.7 Obtain the moisture content from Method 4 (reference method,
or equivalent) or from Method 5.
8.8 Determine the cross-sectional area of the stack or duct at the
sampling location. Whenever possible, physically measure the stack
dimensions rather than using blueprints. Do not assume that stack
diameters are equal. Measure each diameter distance to verify its
dimensions.

10.0 Calibration and Standardization
10.1 Type S Pitot Tube. Before its initial use, carefully examine
the Type S pitot tube top, side, and end views to verify that the face
openings of the tube are aligned within the specifications illustrated
in Figures 2-2 and 2-3. The pitot tube shall not be used if it fails to
meet these alignment specifications. After verifying the face opening
alignment, measure and record the following dimensions of the pitot
tube: (a) the external tubing diameter (dimension Dt, Figure
2-2b); and (b) the base-to-opening plane distances (dimensions
PA and PB, Figure 2-2b). If Dt is
between 0.48 and 0.95 cm \3/16\ and \3/8\ in.), and if PA
and PB are equal and between 1.05 and 1.50 Dt,
there are two possible options: (1) the pitot tube may be calibrated
according to the procedure outlined in Sections 10.1.2 through 10.1.5,
or (2) a baseline (isolated tube) coefficient value of 0.84 may be
assigned to the pitot tube. Note, however, that if the pitot tube is
part of an assembly, calibration may still be required, despite
knowledge of the baseline coefficient value (see Section 10.1.1). If
Dt, PA, and PB are outside the
specified limits, the pitot tube must be calibrated as outlined in
Sections 10.1.2 through 10.1.5.
10.1.1 Type S Pitot Tube Assemblies. During sample and velocity
traverses, the isolated Type S pitot tube is not always used; in many
instances, the pitot tube is used in combination with other source-
sampling components (e.g., thermocouple, sampling probe, nozzle) as
part of an ``assembly.'' The presence of other sampling components can
sometimes affect the baseline value of the Type S pitot tube
coefficient (Reference 9 in Section 17.0); therefore, an assigned (or
otherwise known) baseline coefficient value may or may not be valid for
a given assembly. The baseline and assembly coefficient values will be
identical only when the relative placement of the components in the
assembly is such that aerodynamic interference effects are eliminated.
Figures 2-4, 2-7, and 2-8 illustrate interference-free component
arrangements for Type S pitot tubes having external tubing diameters
between 0.48 and 0.95 cm (\3/16\ and \3/8\ in.). Type S pitot tube
assemblies that fail to meet any or all of the specifications of
Figures 2-4, 2-7, and 2-8 shall be calibrated according to the
procedure outlined in Sections 10.1.2 through 10.1.5, and prior to
calibration, the values of the intercomponent spacings (pitot-nozzle,
pitot-thermocouple, pitot-probe sheath) shall be measured and recorded.
Note: Do not use a Type S pitot tube assembly that is
constructed such that the impact pressure opening plane of the pitot
tube is below the entry plane of the nozzle (see Figure 2-6B).
10.1.2 Calibration Setup. If the Type S pitot tube is to be
calibrated, one leg of the tube shall be permanently marked A, and the
other, B. Calibration shall be performed in a flow system having the
following essential design features:
10.1.2.1 The flowing gas stream must be confined to a duct of
definite cross-sectional area, either circular or rectangular. For
circular cross sections, the minimum duct diameter shall be 30.48 cm
(12 in.); for rectangular cross sections, the width (shorter side)
shall be at least 25.4 cm (10 in.).
10.1.2.2 The cross-sectional area of the calibration duct must be
constant over a distance of 10 or more duct diameters. For a
rectangular cross section, use an equivalent diameter, calculated
according to Equation 2-2 (see Section 12.3), to determine the number
of duct diameters. To ensure the presence of stable, fully developed
flow patterns at the calibration site, or ``test section,'' the site
must be located at least eight diameters downstream and two diameters
upstream from the nearest disturbances.
Note: The eight- and two-diameter criteria are not absolute;
other test section locations may be used (subject to approval of the
Administrator), provided that the flow at the test site has been
demonstrated to be or found stable and parallel to the duct axis.
10.1.2.3 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 steady flow during calibration.
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).
10.1.2.4 Two entry ports, one for each of the standard and Type S
pitot tubes, shall be cut in the test section. The standard pitot entry
port shall be located slightly downstream of the Type S port, so that
the standard and Type S
[[Page 61792]]
impact openings will lie in the same cross-sectional plane during
calibration. To facilitate alignment of the pitot tubes during
calibration, it is advisable that the test section be constructed of
PlexiglasTM or some other transparent material.
10.1.3 Calibration Procedure. Note that this procedure is a
general one and must not be used without first referring to the special
considerations presented in Section 10.1.5. Note also that this
procedure applies only to single-velocity calibration. To obtain
calibration data for the A and B sides of the Type S pitot tube,
proceed as follows:
10.1.3.1 Make sure that the manometer is properly filled and that
the oil is free from contamination and is of the proper density.
Inspect and leak-check all pitot lines; repair or replace if necessary.
10.1.3.2 Level and zero the manometer. Switch on the fan, and
allow the flow to stabilize. Seal the Type S pitot tube entry port.
10.1.3.3 Ensure that the manometer is level and zeroed. Position
the standard pitot tube at the calibration point (determined as
outlined in Section 10.1.5.1), and align the tube so that its tip is
pointed directly into the flow. Particular care should be taken in
aligning the tube to avoid yaw and pitch angles. Make sure that the
entry port surrounding the tube is properly sealed.
10.1.3.4 Read 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.
10.1.3.5 Connect the Type S pitot tube to the manometer and leak-
check. Open the Type S tube entry port. Check the manometer level and
zero. Insert and align the Type S pitot tube so that its A side impact
opening is at the same point as was the standard pitot tube and is
pointed directly into the flow. Make sure that the entry port
surrounding the tube is properly sealed.
10.1.3.6 Read ps, and enter its value in the
data table. Remove the Type S pitot tube from the duct, and disconnect
it from the manometer.
10.1.3.7 Repeat Steps 10.1.3.3 through 10.1.3.6 until three pairs
of p readings have been obtained for the A side of the Type S
pitot tube.
10.1.3.8 Repeat Steps 10.1.3.3 through 10.1.3.7 for the B side of
the Type S pitot tube.
10.1.3.9 Perform calculations as described in Section 12.4. Use
the Type S pitot tube only if the values of A and
B are less than or equal to 0.01 and if the
absolute value of the difference between Cp(A) and
Cp(B) is 0.01 or less.
10.1.4 Special Considerations.
10.1.4.1 Selection of Calibration Point.
10.1.4.1.1 When an isolated Type S pitot tube is calibrated,
select a calibration point at or near the center of the duct, and
follow the procedures outlined in Section 10.1.3. The Type S pitot
coefficients measured or calculated, (i.e. Cp(A) and
Cp(B)) will be valid, so long as either: (1) the isolated
pitot tube is used; or (2) the pitot tube is used with other components
(nozzle, thermocouple, sample probe) in an arrangement that is free
from aerodynamic interference effects (see Figures 2-4, 2-7, and 2-8).
10.1.4.1.2 For Type S pitot tube-thermocouple combinations
(without probe assembly), select a calibration point at or near the
center of the duct, and follow the procedures outlined in Section
10.1.3. The coefficients so obtained will be valid so long as the pitot
tube-thermocouple combination is used by itself or with other
components in an interference-free arrangement (Figures 2-4, 2-7, and
2-8).
10.1.4.1.3 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. The actual blockage
effect will be negligible when the theoretical blockage, as determined
by a projected-area model of the probe sheath, is 2 percent or less of
the duct cross-sectional area for assemblies without external sheaths
(Figure 2-10a), and 3 percent or less for assemblies with external
sheaths (Figure 2-10b).
10.1.4.2 For those probe assemblies in which pitot tube-nozzle
interference is a factor (i.e., those in which the pitot-nozzle
separation distance fails to meet the specifications illustrated in
Figure 2-7A), the value of Cp(s) depends upon the amount of
free space between the tube and nozzle and, therefore, is a function of
nozzle size. In these instances, separate calibrations shall be
performed with each of the commonly used nozzle sizes in place. Note
that the single-velocity calibration technique is acceptable for this
purpose, even though the larger nozzle sizes (>0.635 cm or \1/4\ in.)
are not ordinarily used for isokinetic sampling at velocities around
910 m/min (3,000 ft/min), which is the calibration velocity. Note also
that it is not necessary to draw an isokinetic sample during
calibration (see Reference 19 in Section 17.0).
10.1.4.3 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 () value of 0.01
or less (see Section 10.1.4.4).
10.1.5 Field Use and Recalibration.
10.1.5.1 Field Use.
10.1.5.1.1 When a Type S pitot tube (isolated or in an assembly)
is used in the field, the appropriate coefficient value (whether
assigned or obtained by calibration) shall be used to perform velocity
calculations. For calibrated Type S pitot tubes, the A side coefficient
shall be used when the A side of the tube faces the flow, and the B
side coefficient shall be used when the B side faces the flow.
Alternatively, the arithmetic average of the A and B side coefficient
values may be used, irrespective of which side faces the flow.
10.1.5.1.2 When a probe assembly is used to sample a small duct,
30.5 to 91.4 cm (12 to 36 in.) in diameter, the probe sheath sometimes
blocks a significant part of the duct cross-section, causing a
reduction in the effective value of Cp(s). Consult Reference
9 (see Section 17.0) for details. Conventional pitot-sampling probe
assemblies are not recommended for use in ducts having inside diameters
smaller than 30.5 cm (12 in.) (see Reference 16 in Section 17.0).
10.1.5.2 Recalibration.
10.1.5.2.1 Isolated Pitot Tubes. After each field use, the pitot
tube shall be carefully reexamined in top, side, and end views. If the
pitot face openings are still aligned within the specifications
illustrated in Figure 2-2 and Figure 2-3, it can be assumed that the
baseline coefficient of the pitot tube has not changed. If, however,
the tube has been damaged to the extent that it no longer meets the
specifications of Figure 2-2 and Figure 2-3, the damage shall either be
repaired to restore proper alignment of the face openings, or the tube
shall be discarded.
10.1.5.2.2 Pitot Tube Assemblies. After each field use, check the
face opening alignment of the pitot tube, as in Section 10.1.5.2.1.
Also, remeasure the intercomponent spacings of the assembly. If the
intercomponent spacings have not changed and the face opening alignment
is acceptable, it can be assumed that the coefficient of the assembly
has not changed. If the face
