SUPPLEMENTARY INFORMATION:
I. General Information
A. Does this action apply to me?
The proposed amendments apply to a large number of industries that
are already subject to the current provisions of Parts 51, 60, 61, and
63. Therefore, we have not listed specific affected industries or their
North American Industry Classification System (NAICS) codes here. 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.

II. Background
The EPA catalogs revisions and updates that are needed for test
methods, performance specifications, and associated regulations in 40
CFR parts 51, 60, 61, and 63, and proposes the revisions on a 5- to 10-
year basis. The last methods update was published as a final rule on
October 17, 2000 (65 FR 61744). Many of these needed revisions were
brought to our attention by affected parties and end-users. The
revisions consist of allowable alternatives that were not previously
available, changes that facilitate the use of mercury-free equipment,
and updates needed to correct obsolete provisions or add flexibility.
Corrections to typographical errors and technical errors in equations
and diagrams are also proposed. It is important to note that although
numerous technical
[[Page 1132]]
corrections are being proposed to portions of the subparts in parts 51,
60, 61, and 63, changes are not made to any compliance standard,
reporting, or recordkeeping requirement. For this notice, the EPA is
only proposing revisions to sections of the subpart pertaining to
source testing or monitoring of emissions and operations.
III. Summary of Amendments
A. Appendix M of Part 51
In the introduction of Appendix M of part 51, Methods 3A and 19
would be added to the list of methods not requiring the use of audit
samples. Method 3A is a direct measurement instrumental method which
the audit program does not evaluate, and Method 19 deals with
calculation procedures and not measurement procedures.
B. Method 201A of Appendix M of Part 51
Revisions would be made to the Method 201A published on December
21, 2010. Typographical errors in references to isokinetic sampling
rate, source gas temperatures, stack blockage dimensions by the
sampling heads, and PM10 in Sections 8.3.4(b), 8.3.4.1,
8.7.2.2, and 8.7.5.5(a), respectively, would be corrected. An erroneous
reference to Methods 4A and 5 in Section 10.1 when using a standard
pitot tube would be corrected to refer to Methods 1 and 2. Section
10.5, which addresses Class A volumetric glassware, would be deleted
because it is not needed in the method. For those filters whose weight
cannot be weighed to a constant weight in Section 11.2.1, instruction
would be added to flag and report the data as a minimum value. It would
be noted that the nozzle, front half, and in-stack filter samples need
to be speciated into organic and inorganic fractions to be similar to
the practice in Method 17. The method would also note that neither
Method 17 nor 201A require a separate analysis of the filter for
inorganic and organic particulate matter. Method 201A is often used
together with Method 202 which requires a separate analysis of
inorganic and organic PM. This note would remind testers that a
separate analysis is not required for Method 201A. An incorrect term in
Equation 9 of Section 12.5 would be corrected. In the nomenclature in
Section 12.1, Vb, the volume of aliquot taken for ion
chromatography (IC) analysis, would be deleted since no IC analysis is
performed.
C. Method 202 of Appendix M of Part 51
Revisions would be made to the Method 202 published on December 21,
2010. In Section 8.5.3.1, the text referring to empty impingers would
be deleted because empty impingers are not used. Figures 2 and 3 would
be revised to correctly show the first impinger with an extended stem
instead of a shortened one to be consistent with the method text, and
the condensed moisture and sample portion of the sampling train would
be labeled to make it easy to identify. Figures 4, 5, and 6 would be
republished because they did not print clearly in the December 21,
2010, publication.
D. General Provisions (Subpart A) Part 60
In the General Provisions of part 60, Methods 3A and 19 would be
added to the list of methods not requiring the use of audit samples in
Sec. 60.8(gd). Method 3A is a direct measurement instrumental method
which the audit program does not evaluate, and Method 19 deals with
calculation procedures in lieu of measurement procedures.
A new Sec. 60.8(h) would be added to require that sampling sites
be evaluated for cyclonic flow and stratification before testing.
Cyclonic flow and gas stratification has not been adequately addressed
in the past except for particulate measurement methods. Our experience
has been that gaseous pollutant measurements may also be affected by
these phenomena. Procedures currently used in Methods 1 and 7E would be
referenced for all tests to evaluate the suitability of test locations
and give procedures for testing under conditions of gas stratification
and cyclonic flow to preclude non-representative sampling.
A new Sec. 60.8(i) would be added to allow the use of Method 205
of 40 CFR part 51, Appendix M, ``Verification of Gas Dilution Systems
for Field Instrument Calibrations,'' as an alternative provision
whenever the use of multiple calibration gases is required under Part
60. Method 205 has previously been allowed for different applications
on a case-by-case basis. Method 205 reduces the number of cylinder
gases needed for a test by allowing lower-concentration gases to be
generated from a high-level gas. Section 60.13(d)(1) would be revised
to remove the phrase ``automatically, intrinsic to the opacity
monitor'' which was incorrectly inserted into the paragraph in a past
revision. The title of an organization in a method that is incorporated
by reference would be updated in Sec. 60.17(e), and the edition of the
method referred to in Sec. 60.17(e)(1) would be updated to reflect the
currently available version.
E. Industrial-Commercial-Institutional Steam Generating Units (Subpart
Db) Part 60
In subpart Db, Method 320 would be added as an alternative to the
methods for determining nitrogen oxides (NOX) concentration
in Sec. 60.46b(f)(1)(ii), (h)(1) and (2), and sulfur dioxide
(SO2) concentration in Sec. 60.47b(b)(2). The EPA has
allowed the use of Method 320 in the past on a case-by-case basis and
now believes it is appropriate for general use.
F. Hospital/Medical/Infectious Waste Incinerators (Subpart Ec) Part 60
In subpart Ec, the definition of medical/infectious wastes in Sec.
60.51c would be revised to correct the misspelling of ``cremation.''
G. Sulfuric Acid Plants (Subpart H) Part 60
In Subpart H, an equation for calculating the SO2
emission rate in Sec. 60.84(d) would be corrected.
H. Sewage Treatment Plants (Subpart O) Part 60
In subpart O, a reference to Method 209F in Sec. 60.154(b)(5)
would be revised to reflect a newer available version of the method
(i.e., 2540G).
I. Kraft Pulp Mills (Subpart BB) Part 60
In subpart BB, a typographical error in the equation in Sec.
60.284(c)(3) would be corrected.
J. Stationary Gas Turbines (Subpart GG) Part 60
In subpart GG, the definitions of terms for the equation in Sec.
60.335(b)(l) would be revised to allow the reference combustor inlet
absolute pressure to be measured in millimeters of mercury (mm Hg).
Using the site barometric pressure gives comparable results to the
observed combustor inlet absolute pressure for calculating the mean
NOX emission concentration and would be allowed as an
alternative.
K. Lead-Acid Battery Manufacturing Plants (Subpart KK) Part 60
In subpart KK, Method 29 would be added as an alternative to Method
12 in Sec. 60.374(b)(1)and (c)(2) for determining the lead
concentration and flow rate of the effluent gas. Method 29 is an
accepted method for determining lead under other rules and is
appropriate for this subpart as well. Also, an error in the equation
for calculating the lead emission concentration in 60.374(b)(2) would
be corrected.
[[Page 1133]]
L. Metallic Mineral Processing Plants (Subpart LL) Part 60
In subpart LL, an error in the value of the particulate matter
standard in Sec. 60.382(a)(1) would be corrected from 0.02 g/dscm to
0.05 g/dscm. An alternative procedure, where a single visible emission
observer may conduct visible emission observations for up to three
fugitive, stack, or vent emission points within a 15-second interval,
would be added to Sec. 60.386. This alternative would allow the
observer to take readings in a more cost-effective and timely manner
than currently allowed.
M. Asphalt Processing and Asphalt Roofing Manufacture (Subpart UU) Part
60
In subpart UU, an error in the value of the particulate matter
standard for saturated felt or smooth-surfaced roll roofing in Sec.
60.472(a)(1)(ii) would be corrected from 0.04 kg/Mg to 0.4 kg/Mg.
N. Volatile Organic Compound (VOC) Emissions From Synthetic Organic
Chemical Manufacturing Industry (SOCMI) Distillation Operations
(Subpart NNN) Part 60
In subpart NNN, several paragraphs were renumbered in a previous
amendment, but conforming changes in sections that referenced these
paragraphs were not made. In Sec. 60.660(c)(4) and Sec. 60.665(h)(2)
and (3), these references would be corrected.
O. Stationary Compression Ignition Internal Combustion Engines (Subpart
IIII) Part 60
In Subpart IIII, the use of Method 1 or 1A for sampling point
selection would be dropped, and single-point sampling at the centroid
of the exhaust would be added. The exhausts of most regulated engines
are too small and not equipped with sampling ports. This makes it
difficult to divide the exhaust into multiple sampling-point locations
as required by Methods 1 and 1A. Table 7 would be revised to delete the
requirement to use Method 1 or 1A.
P. Stationary Spark Ignition Internal Combustion Engines (Subpart JJJJ)
Part 60
In Subpart JJJJ, the exhausts of most regulated engines do not
contain sampling ports and are too small to be subdivided into multiple
sampling-point locations. Table 2 would be revised to delete the
requirement to use Method 1 or 1A for determining sampling site and
sampling-point location, and instruction would be added to sample at
the centroid of the exhaust.
Q. Method 1 of Appendix A-1 of Part 60
In Method 1, Section 11.2.2 would be clarified to note that it
specifically applies to gaseous measurements. The provisions in the
section for determining exhaust gas stratification would be streamlined
to make them consistent with the new stratification provisions in
Method 7E. Figures 1-1 and 1-2 would be clarified to note that the
horizontal coordinates represent the duct diameters from the sampling
point to the flow disturbance and not simply the duct diameters from
the flow disturbance. Figure 1-2 would also be corrected to show the
proper demarcation between the requirement for 12 and 16 sampling
points. The test for the presence or absence of cyclonic flow would be
required for all tests instead of recommended at sites suspected of
having cyclonic flow.
R. Method 2 of Appendix A-1 of Part 60
In Method 2, a pressure stability specification that has been
lacking for the pitot tube leak-check would be added to clearly note
the desired stability. An erroneous reference to a Figure 2-6B would be
corrected to reference Figure 2-7B. An error in a term in the
denominator of Equation 2-7 would be corrected to the average of the
square root of delta P rather than the square root of the average delta
P. The velocity constant in English units used in Equation 2-7 would be
corrected by changing m/sec to ft/sec. The term for absolute
temperature in Equations 2-7 and 2-8 would be corrected to represent
the average of the absolute temperatures; an inadvertently omitted term
would be added to Section 12.1 for the average absolute temperature;
and calibrating a barometer against a NIST-traceable barometer would be
added as an alternative to calibrating against a mercury barometer to
facilitate the use of mercury-free products.
S. Method 2A of Appendix A-1 of Part 60
In Method 2A, calibrating a barometer against a NIST-traceable
barometer would be added as an alternative to calibrating against a
mercury barometer to facilitate the use of mercury-free products.
T. Method 2B of Appendix A-1 of Part 60
In Method 2B, nomenclature errors would be corrected and the
assumed ambient carbon dioxide concentration used in the calculations
would be changed from 300 to 380 ppm to closer approximate current
ambient levels.
U. Method 2D of Appendix A-1 of Part 60
In Method 2D, calibrating a barometer against a NIST-traceable
barometer would be added as an alternative to calibrating against a
mercury barometer to facilitate the use of mercury-free products.
V. Method 3A of Appendix A-2 of Part 60
In Method 3A, a redundant sentence noting that pre-cleaned air may
be used for the high-level calibration gas would be deleted.
W. Method 4 of Appendix A-3 of Part 60
In Method 4, the English value for the leak rate exceedance in
Section 9.1 would be corrected from 0.20 cfm to 0.020 cfm. Method 6A,
Method 320, and a calculation using F-factors would be added as
alternatives to Method 4 for the moisture determination. These are
logical alternatives in cases where Methods 6A and 320 are already
being used, and the F-factors approach can save both time and expenses
in some cases.
X. Method 5 of Appendix A-3 of Part 60
In Method 5, a clarification would be added that the deionized
water used in the analysis of material caught in the impingers must
have <=0.001 percent residue; the factor K would be corrected to K' in
Equation 5-13; calibrating a barometer against a NIST-traceable
barometer would be added as an alternative to calibrating against a
mercury barometer to facilitate the use of mercury-free products;
calibrating a temperature sensor against a thermometer equivalent to a
mercury-in-glass thermometer would be added as an alternative to
calibrating against a mercury-in-glass thermometer to facilitate the
use of mercury-free products; rechecking temperature sensors for the
filter holder and metering system after each test has been found to be
sufficient and would replace having sensors calibrated within 3 [deg]F;
the option to check the probe heater calibration after a test at a
single point using a reference thermometer would be added; the use of
weather station barometric pressure corrected to testing point
elevation would be added as an option to having an on-site barometer;
mention of stopcock grease for air-tight impinger seals would be
deleted since it is outdated and not often used; a smaller acetone
cleanup blank is determined sufficient and a single blank per container
would be allowed in place of a blank from each wash bottle; Section
10.3.3 would be clarified as a post-test
[[Page 1134]]
metering system calibration check rather than a metering system
calibration, and an alternative metering check procedure would be
added; the Isostack metering system would be noted as an acceptable
system for determining sample flow rates; the use of a Teflon filter
holder would be allowed without having to obtain the Administrator's
approval first; and Reference 13 for post-test calibration would be
added to the method.
Y. Method 5A of Appendix A-3 of Part 60
In Method 5A, mercury-free thermometers would be added as an
alternative to mercury-in-glass thermometers to facilitate the use of
mercury-free products.
Z. Method 5E of Appendix A-3 of Part 60
In Method 5E, the use of the Rosemount Model 2100A total organic
content analyzer would be replaced with the Tekmar-Dohrmann or
equivalent analyzer, as neither the Rosemount analyzer nor any similar
dual-injection analyzer is currently manufactured. Also, Section 12.5
inadvertently labels the equation for total particulate concentration
as Eq. 5E-4, which would be corrected to Eq. 5E-5.
AA. Method 5H of Appendix A-3 of Part 60
In Method 5H, Section 12.1 would be revised to add missing terms
Ci, Co, Qi, and Qo; and
procedures for the determination of an alternative tracer gas flow rate
would be added.
BB. Method 6 of Appendix A-4 of Part 60
In Method 6, calibrating a temperature sensor against a thermometer
equivalent to a mercury-in-glass thermometer would be added as an
alternative to using a mercury-in-glass thermometer, and calibrating a
barometer against a NIST-traceable barometer would be added as an
alternative to calibrating against a mercury barometer. These revisions
would facilitate the use of mercury-free products.
CC. Method 6C of Appendix A-4 of Part 60
In Section 4.0 of Method 6C, an incorrect reference to Section 4.1
of Method 6 would be corrected to reference Section 4.0 of Method 7E.
Provisions that were removed from the original method that addressed
potential quenching effects in fluorescence analyzers would be added
again. It was previously believed that current fluorescence analyzers
are not affected by quenching effects; however, we were informed that
the provisions are still needed in many cases.
DD. Method 7 of Appendix A-4 of Part 60
In Method 7, procedures would be added to avoid biased results when
sampling under conditions of high SO2 concentrations;
calibrating a barometer against a NIST-traceable barometer would be
added as an alternative to calibrating against a mercury barometer; and
calibrating a temperature sensor against a thermometer equivalent to a
mercury-in-glass thermometer would be added as an alternative to using
a mercury-in-glass thermometer. These revisions would facilitate the
use of mercury-free products.
EE. Method 7A of Appendix A-4 of Part 60
In Method 7A, new procedures would be added to avoid biased results
when sampling under conditions of high SO2 concentrations,
and calibrating a temperature sensor against a thermometer equivalent
to a mercury-in-glass thermometer would be added as an alternative to
using a mercury-in-glass thermometer to facilitate the use of mercury-
free products.
FF. Method 7E of Appendix A-4 of Part 60
In Method 7E, the instructions for choosing the high-level
calibration gas would be clarified. Instructions would be added to
minimize contact of the sample with any condensate to reduce the chance
of sample loss, and an error in the traverse point locations used to
determine stratification across large stacks would be corrected. A
statement noting that the stratification test is not required at
sources with temporally varying emissions or low-concentration
emissions would be added since a stratification test under such
conditions would be meaningless or difficult to pass. The basis of a
stable response for measurements in the system response time
determination would be revised in Section 8.2.5 to conform with Section
8.2.6. The response time reading would be recorded after the
concentration reading has reached 95 percent or within 0.5 ppm of a
stable response for the gas instead of after reaching 95 percent of the
certified gas concentration. This change removes a potential conflict
between the response time stable reading criterion and the bias or
system calibration error test criterion. Alternative sampling bags made
of materials other than Tedlar would be allowed if the materials are
applicable for retaining the compounds of interest. Tedlar bags are no
longer being produced.
GG. Method 8 of Appendix A-4 of Part 60
In Method 8, corrections would be made to errors in the sample
aliquot volumes required for containers 1 and 2 and in the values for
Va and Vsoln. Figure 8-1 would be clarified to
identify which impingers collect sulfuric acid/sulfur trioxide and
which collect sulfur dioxide.
HH. Method 10 of Appendix A-4 of Part 60
Method 10 would be revised to allow the use of sample tanks as an
alternative to flexible bags for sample collection. Tanks are an
acceptable collection medium, are currently allowed for carbon monoxide
in other EPA methods, and are appropriate for Method 10 as well.
II. Methods 10A and 10B of Appendix A-4 of Part 60
In Methods 10A and 10B, sampling bags made of materials other than
Tedlar would be allowed if the materials have the sample retaining
qualities of Tedlar. Tedlar bags are no longer produced.
JJ. Method 11 of Appendix A-5 of Part 60
Method 11 would be revised to address sample breakthrough at high
concentrations. An additional collection impinger would be added to the
train whenever the final impinger solution exhibits a yellow color.
Calibrating a temperature sensor against a thermometer equivalent to a
mercury-in-glass thermometer would be added as an alternative to using
a mercury-in-glass thermometer to facilitate the use of mercury-free
products.
KK. Method 12 of Appendix A-5 of Part 60
Method 12 would be revised to allow an analysis by inductively
coupled plasma-atomic emission spectrometry (ICP-AES) or cold vapor
atomic fluorescence spectrometry (CVAFS) as alternatives to atomic
absorption (AA) analysis. The ICP-AES is currently an approved
technique for lead analysis in Method 29, and CVAFS offers comparable
sensitivity and precision to AA.
LL. Method 14A of Appendix A-5 of Part 60
In Section 10.1.1 of Method 14A, we inadvertently referenced Figure
5-6.
[[Page 1135]]
This reference would be corrected to Figure 5-5.
MM. Method 16A of Appendix A-6 of Part 60
In Method 16A, the applicability section would note that method
results may be biased low if used at sources other than kraft pulp
mills where stack oxygen levels may be lower.
NN. Method 18 of Appendix A-6 of Part 60
In Method 18, sampling bags made of materials other than Tedlar
would be allowed if the materials are applicable for retaining the
compounds of interest. Tedlar bags are no longer produced.
OO. Method 23 of Appendix A-7 of Part 60
In Method 23, the requirement in Section 2.2.7 that silica gel be
stored in metal containers is unnecessary and would be deleted. Section
4.2.7 would be clarified to note that the used silica gel should be
transferred to its original container or other suitable vessel if
moisture is being determined. If moisture is not being determined, the
spent silica gel may be discarded. Mercury-free thermometers would be
added as an alternative to using mercury-in-glass thermometers to
facilitate the use of mercury-free products.
PP. Method 24 of Appendix A-7 of Part 60
Method 24 would be revised to cite only ASTM Method D2369 and not
the specific sections of the method, since the section numbers may
change with periodic updates.
QQ. Method 25 of Appendix A-7 of Part 60
In Method 25, more detailed information would be added to describe
the filters used for sample collection.
RR. Method 25C of Appendix A-7 of Part 60
Method 25C would be revised to allow sampling lines made of Teflon.
Probes that have closed points and are driven below surface in a single
step and withdrawn at a distance to create a gas gap would be allowed
as acceptable substitutes to using pilot probes and the auger
procedure. An equation for correcting the sample nitrogen concentration
for tank dilution would be added as a supplemental calculation option.
SS. Method 25D of Appendix A-7 of Part 60
In Method 25D, errors in cross-references within the method would
be corrected.
TT. Method 26 of Appendix A-8 of Part 60
Method 26 would be revised to allow the use of heated Teflon probes
in place of glass-lined probes. Conflicting temperature requirements
for the sampling system would be clarified. The note to keep the probe
and filter temperature at least 20 [deg]C above the source temperature
would be removed because the specification is not needed at higher
temperature stacks. The location of the thermocouple that monitors the
collected gas temperature would be clarified as being in the gas
stream, not the filter box. Method 26A would be an acceptable
alternative to Method 26 since the methods are fundamentally similar
and give comparable results when determining non-particulate hydrogen
halides.
UU. Method 29 of Appendix A-8 of Part 60
Method 29 would be revised to allow samples to be analyzed by CVAFS
as an alternative to AA analysis since CVAFS is as sensitive and
precise as AA.
VV. Method 30B of Appendix A-8 of Part 60
In Method 30B, calibrating a barometer against a NIST-traceable
barometer would be added as an alternative to calibrating against a
mercury barometer to facilitate the use of mercury-free products.
Table 9-1 and the method text would be revised to amend the quality
assurance/quality control criteria for sorbent trap section 2
breakthrough and sample analysis. These revisions would address
compliance testing and relative accuracy testing of mercury monitoring
systems currently being conducted at much lower emission
concentrations.
For compliance/emissions testing, the specification in Table 9-1
for sample analysis would be revised to require analytical results be
within the valid calibration range down to a concentration of 0.01
[micro]g/dscm. This will ensure that measurements at the low levels
being measured under recent rulemakings are of known, acceptable, and
consistent quality. For relative accuracy testing of mercury monitoring
systems, the sample analysis specification in Table 9-1 would remain
the same, but the breakthrough criteria for second section in the
sorbent traps would be revised to provide additional flexibility where
mercury concentrations are less than 0.5 [micro]g/dscm.
Finally, Method 30B would be revised to include the most up to date
citation for determining the method detection limit or MDL.
WW. Performance Specification 1 of Appendix B of Part 60
In Performance Specification 1, the terms ``full scale'' and
``span'' would be noted as having the same meaning.
XX. Performance Specification 3 of Appendix B of Part 60
In Performance Specification 3, a statement that allows the
relative accuracy to be within 20 percent of the reference method would
be added to establish the original intent of the rule. This statement
was inadvertently deleted in a previous amendment.
YY. Performance Specification 4 of Appendix B of Part 60
Performance Specification 4 would be revised to remove the required
use of the interference trap specified in Method 10 when evaluating
non-dispersive infrared continuous emission monitoring systems against
Method 10. This is an old requirement, and the trap is not needed with
modern analyzers.
ZZ. Performance Specification 4B of Appendix B of Part 60
Performance Specification 4B would be clarified to note that
Equation 1 in Section 7.1.1 for calculating calibration error only
applies to the carbon monoxide monitor and not the oxygen monitor. It
would be noted for the oxygen monitor that the calibration error should
be expressed as the oxygen concentration difference between the mean
monitor and reference value at three levels.
AAA. Performance Specification 7 of Appendix B of Part 60
Performance Specification 7 would be revised to allow Methods 15
and 16 as reference methods in addition to Method 11. Methods 15 and 16
are approved for determining hydrogen sulfide and are appropriate for
this application. Methods 15 and 16 are approved EPA reference methods
for a number of sources. A pertinent reference would also be added to
the references section.
BBB. Performance Specification 11 of Appendix B of Part 60
In Performance Specification 11, errors in the denominators of
Equations 11-1 and 11-2 would be corrected.
[[Page 1136]]
CCC. Performance Specification 15 of Appendix B of Part 60
In Performance Specification 15, the general references to 40 CFR
part 60, Appendix B for the relative accuracy analysis procedure would
specifically cite Performance Specification 2 of 40 CFR part 60,
Appendix B.
DDD. Performance Specification 16 of Appendix B of Part 60
Performance Specification 16 would be clarified to answer questions
that have arisen since its publication. Retesting a predictive emission
monitoring system (PEMS) after a sensor is replaced would be explained
more clearly. Allowances would be made for relative accuracy testing at
three load or production rate levels in cases where the key operating
parameter could not be readily altered. Additional instruction would be
added for performing the relative accuracy audit (RAA). An error in the
RAA acceptance criterion would be corrected, and an alternative
acceptance criterion for low concentration measurements would be added.
The yearly relative accuracy test audit would clearly note that the
statistical tests in Section 8.3 are not required. An incorrect
reference to Equation 16-4 in Section 12.4 would be corrected.
EEE. Procedure 1 of Appendix F of Part 60
In Procedure 1, the relevant performance specification would be
cited for the RAA calculation instead of using the current Equation 1-1
which is not appropriate for all pollutants.
FFF. Procedure 2 of Appendix F of Part 60
In Procedure 2, Equations 2-2 and 2-3 would be revised to have the
full-scale value in the denominator, which is more appropriate than the
up-scale check value. The denominator of equation 2-4 would be revised
to include the volume of the reference device rather than the full-
scale value. These revisions reflect the original intent of the rule.
GGG. Procedure 5 of Appendix F of Part 60
In Procedure 5, the second section listed as Section 6.2.6 would be
correctly numbered as Section 6.2.7.
HHH. General Provisions (Subpart A) Part 61
In the General Provisions of part 61, Methods 3A and 19 would be
added to the list of methods not requiring the use of audit samples in
Sec. 61.13(e). These methods were inadvertently omitted in the
original rule.
III. Beryllium (Subpart C) Part 61
In the beryllium National Emission Standards for Hazardous Air
Pollutants (NESHAP), Method 29 of part 60 would be added as an
alternative to Method 104 in Sec. 61.33(a) for emissions testing since
Method 29 is used to determine beryllium under other rules and is
appropriate for this subpart as well.
JJJ. Beryllium Rocket Motor Firing (Subpart D) Part 61
In the beryllium rocket motor firing NESHAP, a conversion error in
the emission standard in Sec. 61.42(a) would be corrected.
KKK. Mercury (Subpart E) Part 61
In the mercury NESHAP, Method 29 of part 60 would be added as an
alternative to Method 101A in Sec. 61.53(d)(2) for emissions testing
since Method 29 is used to determine mercury under other rules and is
appropriate for this subpart as well.
LLL. Inorganic Arsenic Emissions From Glass Manufacturing Plants
(Subpart N) Part 61
In the glass manufacturing plants NESHAP, Method 29 in Appendix A
of part 60 would be added as an alternative to Method 108 in Sec.
61.164(d)(2)(i) for determining the arsenic emissions rate and in Sec.
61.164(e)(1)(i) and (e)(2) for determining the arsenic concentration in
a gas stream. Method 29 is used to determine arsenic under other rules
and is appropriate for this subpart as well.
MMM. Method 101 of Appendix B of Part 61
Method 101 would be revised to allow analysis by ICP-AES or CVAFS
as alternatives to AA analysis. These techniques are allowed for
determining mercury in other approved methods and are appropriate for
Method 101 as well. They were not available when Method 101 was
promulgated.
NNN. Method 101A of Appendix B of Part 61
Method 101A would be revised to allow analysis by ICP-AES or CVAFS
as alternatives to AA analysis. These techniques are allowed for
determining mercury in other approved methods and are appropriate for
Method 101A as well. They were not available when Method 101A was
promulgated.
OOO. Method 102 of Appendix B of Part 61
In Method 102, mercury-free thermometers would be allowed in place
of mercury-in-glass thermometers to facilitate the use of mercury-free
products.
PPP. Method 104 of Appendix B of Part 61
Method 104 would be revised to allow analysis by ICP-AES as an
alternative to AA analysis. This new technique is acceptable for
measuring beryllium and was not available when Method 104 was
promulgated. A new alternative procedures section would be added to
address ICP-AES.
QQQ. Methods 108 and 108A of Appendix B of Part 61
Methods 108 and 108A would be revised to allow analysis by ICP-AES
as an alternative to AA analysis. This new technique is acceptable for
measuring arsenic and was not available when Methods 108 and 108A were
promulgated. A new alternative procedures section would be added to
address ICP-AES.
RRR. General Provisions (Subpart A) Part 63
In the General Provisions of part 63, Methods 3A and 19 would be
added to the list of methods not requiring the use of audit samples in
Sec. 63.7(c). These were inadvertent omissions of the original rule.
In Sec. 63.8(f)(6)(iii), an incorrect reference to a section of
Performance Specification 2 would be corrected.
SSS. Synthetic Organic Chemical Manufacturing Industry (Subpart G) Part
63
Subpart G would be revised to allow the use of Method 8260B in the
SW-846 Compendium of Methods or Method 316 to determine hazardous air
pollutant concentrations in wastewater streams in Sec.
63.144(b)(5)(i). Both methods are appropriate for this application but
were not considered during the original rule development.
TTT. Chromium Emissions From Hard and Decorative Chromium
Electroplating and Chromium Anodizing Tanks (Subpart N) Part 63
South Coast Air Quality Management District Method 205.1 would be
added as a testing option for measuring total chromium. Method 205.1 is
appropriate for this application, but its application to this rule was
not considered during the original rule development.
UUU. Ethylene Oxide Emissions Standards for Sterilization Facilities
(Subpart O) Part 63
The ethylene oxide emissions standards for sterilization facilities
NESHAP would be revised to allow
[[Page 1137]]
California Air Resources Board (CARB) Method 431 as an alternative to
the procedures in Sec. 63.365(b) for determining efficiency at the
sterilization chamber vent. Method 431 is appropriate for this
application but was not considered during the original rule
development. An error in a reference to a section in Performance
Specification 8 would also be corrected.
VVV. Marine Tank Vessel Loading Operations (Subpart Y) Part 63
The marine tank vessel loading operations NESHAP would be revised
to allow Method 25B as an alternative to Method 25A in Sec.
63.565(d)(5) for determining the average volatile organic compound
(VOC) concentration upstream and downstream of recovery devices. Method
25B would be allowed as an alternative to Methods 25 and 25A for
determining the percent reduction in VOC in Sec. 63.565(d)(8), and the
requirement that Method 25B be validated according to Method 301 in
Sec. 63.565(d)(10) would be added. Method 25B would also be added as
an alternative to Method 25A in determining the baseline outlet VOC
concentration in Sec. 63.565(g). Method 25B uses a different detector
than Method 25A but gives comparable results to Method 25A in these
applications.
WWW. Aerospace Manufacturing and Rework Facilities (Subpart GG) Part 63
The aerospace manufacturing and rework facilities NESHAP would be
revised to remove an incorrect reference to the location of Method 319
in Sec. 63.750(o).
XXX. Pharmaceuticals Production (Subpart GGG) Part 63
The pharmaceuticals production NESHAP would be revised to allow
Method 320 as an alternative to Method 18 for demonstrating that a vent
is not a process vent. Method 320 is a broadly applicable method that
is acceptable in this application because it is self-validating.
YYY. Secondary Aluminum Production (Subpart RRR) Part 63
The secondary aluminum production NESHAP would be revised to allow
Method 26 as an alternative to Method 26A in Sec. 63.1511(c)(9) for
determining hydrochloric acid (HCl) concentration. Method 26 is the
non-isokinetic version of Method 26A and is being allowed in all cases
where non-isokinetic sampling for HCl is performed.
ZZZ. Manufacturing of Nutritional Yeast (Subpart CCCC) Part 63
Table 2 in the manufacturing of nutritional yeast NESHAP would be
revised to delete the requirements to use Methods 1, 2, 3, and 4 when
measuring VOC by Method 25A. Methods 1, 2, 3, and 4 are required for
particulate matter sampling and the VOC in this application is normally
not particulate in nature.
AAAA. Petroleum Refineries: Catalytic Cracking Units, Catalytic
Reforming Units, and Sulfur Recovery Units (Subpart UUUU) Part 63
Table 4 in the petroleum refineries: catalytic cracking units,
catalytic reforming units, and sulfur recovery units NESHAP would be
revised to allow Method 320 as an alternative to Method 18 for
determining control device efficiency for organic compounds. Method 320
is a broadly applicable method that is acceptable in this application
because it is self-validating.
BBBB. Stationary Reciprocating Internal Combustion Engines (Subpart
ZZZZ) Part 63
Table 4 in the stationary reciprocating internal combustion engines
NESHAP would be revised to clarify that a heated probe is not necessary
when using ASTM D6522 to measure oxygen or carbon dioxide
concentrations because condensed moisture is normally not an
interferent to these compounds. The requirement to use Method 1 or 1A
for sampling site and sampling point location would be deleted because
the exhausts are small and have temporally varying emissions.
Instruction would be added to sample at the centroid of the stack.
CCCC. Method 306 of Appendix A of Part 63
Method 306 would be revised to remove references to two figures
that do not exist and to add clarifying information about the
conditions under which ICP is appropriate for sample analysis.
Alternative mercury-free thermometers also would be added as
alternatives to mercury-in-glass thermometers to facilitate the use of
mercury-free products.
DDDD. Method 306A of Appendix A of Part 63
In Method 306A, information would be added to clarify the
conditions under which sample filtering is required.
EEEE. Methods 308, 315, and 316 of Appendix A of Part 63
In Methods 308, 315, and 316, calibrating a temperature sensor
against a thermometer equivalent to a mercury-in-glass thermometer
would be added as an alternative to mercury-in-glass thermometers to
facilitate the use of non-mercury products. Alternative mercury-free
thermometers would be added as an alternative to using a mercury-in-
glass thermometers.
FFFF. Method 321 of Appendix A of Part 63
In Method 321, the term for dilution factor in the calculations
would be clarified.
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 no requirements in
most methods 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-, or 12-point traverse is used for the test.
There are no requirements to check for cyclonic flow in Method 7E.
We have 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 regulatory docket. We are also reconsidering the appropriateness of
a diluent gas for the test instead of the regulated pollutant.
In this proposed rule, we would 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 your
comments and data to aid in establishing better procedures.
[[Page 1138]]
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 (EO) 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
This action does not impose an information collection burden under
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq.
Burden is defined at 5 CFR 1320.3(b). The amendments being proposed in
this action to the test methods and testing regulations do not add
information collection requirements but make needed corrections and
updates to existing testing methodology.
C. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA) generally requires an agency
to prepare a regulatory flexibility analysis of any rule subject to
notice and comment rulemaking requirements under the Administrative
Procedure Act or any other statute unless the agency certifies that the
rule will not have a significant economic impact on a substantial
number of small entities. Small entities include small businesses,
small organizations, and small governmental jurisdictions.
For purposes of assessing the impacts of this rule on small
entities, small entity is defined as (1) A small business as defined by
the Small Business Administration's (SBA) regulations at 13 CFR
121.201; (2) a small governmental jurisdiction that is a government of
a city, county, town, school district or special district with a
population of less than 50,000; and (3) a small organization that is
any not-for-profit enterprise which is independently owned and operated
and is not dominant in its field.
After considering the economic impacts of this rule on small
entities, I certify that this action will not have a significant
economic impact on a substantial number of small entities. This
proposed rule will neither impose emission measurement requirements
beyond those specified in the current regulations, nor will it change
any emission standard. This proposed action will not impose any new
requirements on small entities. We continue to be interested in the
potential impacts of the proposed rule on small entities and welcome
comments on issues related to such impacts.
D. Unfunded Mandates Reform Act
This action contains no Federal mandates under the provisions of
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C.
1531-1538 for State, local, or tribal governments or the private
sector. The action imposes no enforceable duty on any State, local or
tribal governments or the private sector. Therefore, this action is not
subject to the requirements of sections 202 or 205 of the UMRA. This
action is also not subject to the requirements of section 203 of UMRA
because it contains no regulatory requirements that might significantly
or uniquely affect small governments. This action corrects and updates
current testing regulations and does not add any new requirements.
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, as
specified in Executive Order 13132. This action simply corrects minor
errors and makes updates to current source testing methods to maintain
their original intent. Thus, Executive Order 13132 does not apply to
this action. In the spirit of Executive Order 13132, and consistent
with the EPA policy to promote communications between the EPA and State
and local governments, the EPA specifically solicits comment on this
proposed rule from State and local officials.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications, as specified in
Executive Order 13175 (65 FR 67249, November 9, 2000). This proposed
rule imposes no requirements on tribal governments. This action simply
corrects and updates current testing regulations. Thus, Executive Order
13175 does not apply to this action. The EPA specifically solicits
additional comment on this proposed action from tribal officials.
G. Executive Order 13045: Protection of Children From Environmental
Health and Safety Risks
The EPA interprets EO 13045 (62 FR 19885, April 23, 1997) as
applying only to those regulatory actions that concern health or safety
risks, such that the analysis required under section 5-501 of the EO
has the potential to influence the regulation. This action is not
subject to EO 13045 because it does not establish an environmental
standard intended to mitigate health or safety risks.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This action is not subject to Executive Order 13211 (66 FR 28355
(May 22, 2001)), because it is not a significant regulatory action
under Executive Order 12866.
I. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (``NTTAA''), Public Law 104-113 (15 U.S.C. 272 note)
directs the EPA to use voluntary consensus standards in its 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, and business practices) that are developed or adopted by
voluntary consensus standards bodies. NTTAA directs the EPA to provide
Congress, through OMB, explanations when the Agency decides not to use
available and applicable voluntary consensus standards.
This proposed rulemaking involves technical standards. The EPA
proposes to use ASTM D975-076, developed and adopted by the American
Society for Testing and Materials (ASTM). This standard may be obtained
from ASTM at 100 Barr Harbor Drive, P.O. Box C700, West Conshohocken,
PA 19428-2959. ASTM D975-076 has been determined to be at least as
stringent as currently required ASTM D396 for defining ``distillate
oil.'' ASTM D975-076 is required in some State permits for this purpose
and end users have asked that it be allowed as an alternative to D396
under 40 CFR 60.41c.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
Executive Order (EO) 12898 (59 FR 7629 (Feb. 16, 1994)) establishes
Federal executive policy on environmental justice. Its main provision
directs Federal agencies, to the greatest extent practicable and
permitted by law, to make environmental justice part of their mission
by identifying and addressing, as appropriate, disproportionately high
[[Page 1139]]
and adverse human health or environmental effects of their programs,
policies, and activities on minority populations and low-income
populations in the United States.
The EPA has determined that this proposed rule will not have
disproportionately high and adverse human health or environmental
effects on minority or low-income populations because it does not
affect the level of protection provided to human health or the
environment. This rule corrects and updates current testing regulations

Revisions to Test Methods and Testing Regulations
List of Subjects in 40 CFR Parts 51, 60, 61, and 63
Environmental protection, Air pollution control, Test methods and
procedures, and Performance specifications.
Dated: November 29, 2011.
Lisa P. Jackson,
Administrator.
For the reasons stated in the preamble, the Environmental
Protection Agency proposes to amend title 40, chapter I of the Code of
Federal Regulations as follows:
PART 51--REQUIREMENTS FOR PREPARATION, ADOPTION, AND SUBMITTAL OF
IMPLEMENTATION PLANS
1. The authority citation for part 51 continues to read as follows:
Authority: 23 U.S.C. 101; 42 U.S.C. 7401-7671q.
2. Amend Appendix M by revising section 4a. to read as follows:
Appendix M to Part 51--Recommended Test Methods for State
Implementation Plans
* * * * *
4. * * *
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, 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, and Methods 303, 318, 320, and 321 of Appendix A of Part
63. 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 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.
* * * * *
3. Amend Method 201A of Appendix M as follows:
a. By revising sections 8.3.4(b) and 8.3.4.1.
b. By revising sections 8.7.2.2 and 8.7.5.5(a).
c. By revising the introductory text of section 10.1.
d. By revising section 11.2.1.
e. By revising Equation 9 in section 12.5.
f. By removing section 10.5.
g. By removing the term ``Vb'' and its definition from
section 12.1.
Method 201A--Determination of PM10 and PM2.5
Emissions From Stationary Sources (Constant Sampling Rate Procedure)
* * * * *
8.3.4 * * *
(b) The appropriate nozzle to maintain the required gas sampling
rate for the velocity pressure range and isokinetic range. If the
isokinetic range cannot be met (e.g., batch processes, extreme
process flow or temperature variation), void the sample or use
methods subject to the approval of the Administrator to correct the
data. The acceptable variation from isokinetic sampling is 80 to 120
percent and no more than 100 21 percent (2 out of 12 or
5 out of 24) sampling points outside of this criteria.
* * * * *
8.3.4.1 Preliminary traverse. You must use an S-type pitot tube
with a conventional thermocouple to conduct the traverse. Conduct
the preliminary traverse as close as possible to the anticipated
testing time on sources that are subject to hour-by-hour gas flow
rate variations of approximately 20 percent and/or gas
temperature variations of approximately 10 [deg]C
( 18; [deg]F). (Note: You should be aware that these
variations can cause errors in the cyclone cut diameters and the
isokinetic sampling velocities.)
* * * * *
8.7.2.2 Probe blockage factor. You must use Equation 26 to
calculate an average probe blockage correction factor
(bf) if the diameter of your stack or duct is between
25.7 and 36.4 inches for the combined PM2.5/
PM10 sampling head and pitot and between 18.8 and 26.5
inches for the PM2.5 cyclone and pitot. A probe blockage
factor is calculated because of the flow blockage caused by the
relatively large cross-sectional area of the cyclone sampling head,
as discussed in Section 8.3.2.2 and illustrated in Figures 8 and 9
of Section 17. You must determine the cross-sectional area of the
cyclone head you use and determine its stack blockage factor. (Note:
Commercially-available sampling heads (including the PM10
cyclone, PM2.5 cyclone, pitot and filter holder) have a
projected area of approximately 31.2 square inches when oriented
into the gas stream. As the probe is moved from the outermost to the
innermost point, the amount of blockage that actually occurs ranges
from approximately 13 square inches to the full 31.2 inches plus the
blockage caused by the probe extension. The average cross-sectional
area blocked is 22 square inches.
* * * * *
8.7.5.5 * * *
(a) Container 1, Less than or equal to PM2.5
micrometer filterable particulate. Use tweezers and/or clean
disposable surgical gloves to remove the filter from the filter
holder. Place the filter in the Petri dish that you labeled with the
test identification and Container 1. Using a dry brush and/
or a sharp-edged blade, carefully transfer any PM and/or filter
fibers that adhere to the filter holder gasket or filter support
screen to the Petri dish. Seal the container. This container holds
particles less than or equal to 2.5 micrometers that are caught on
the in-stack
[[Page 1140]]
filter. (Note: If the test is conducted for PM10 only,
then Container 1 would be for less than or equal to
PM10 micrometer filterable particulate.)
* * * * *
10.1 Gas Flow Velocities. You must use an S-type pitot tube that
meets the required EPA specifications (EPA Publication 600/4-77-
0217b) during these velocity measurements. (Note: If, as specified
in Section 8.7.2.3, testing is performed in stacks less than 26.5
inches in diameter, testers may use a standard pitot tube according
to the requirements in Method 1 or 2 of Appendix A-3 to Part 60.)
You must also complete the following:
* * * * *
11.2.1 Container 1, Less than or Equal to
PM2.5 Micrometer Filterable Particulate. Transfer the
filter and any loose particulate from the sample container to a
tared weighing dish or pan that is inert to solvent or mineral
acids. Desiccate for 24 hours in a desiccator containing anhydrous
calcium sulfate. Weigh to a constant weight and report the results
to the nearest 0.1 mg. (See Section 3.0 for a definition of constant
weight.) If constant weight requirements cannot be met, data should
be reported and flagged as a minimum value. (Note: Regardless of the
stack temperature, you are not required to speciate the Method 201A
nozzle, front half or in-stack filter sample into organic and
inorganic fractions. Neither Method 17 nor 201A require separate
analysis of the filter for inorganic and organic PM. Since the in-
stack filter samples collected at <=30 [deg]C (85 [deg]F) may
include both filterable insoluble particulate and condensable
particulate, the filter should be weighed after desiccation but not
extracted since insoluble particulate will not be recovered from the
extraction.)

4. Amend Method 202 of Appendix M as follows:
a. By revising the introductory text in section 8.5.3.1.
b. By revising section 11.2.2.
c. By revising Figures 2, 3, 4, 5, and 6 in section 18.0.
Method 202--Dry Impinger Method for Determining Condensable Particulate
Emissions from Stationary Sources
* * * * *
8.5.3.1 If you choose to conduct a pressurized nitrogen purge on
the complete CPM sampling train, you may quantitatively transfer the
water collected in the condenser and the water dropout impinger to
the backup impinger as an alternative to replacing the short stem
impinger insert with a long stem insert prior to purging the
sampling train. You must measure the water combined in the backup
impinger and record the volume or weight as part of the moisture
collected during sampling as specified in Section 8.5.3.4.
* * * * *
11.2.2 CPM Container 1, Aqueous Liquid Impinger
Contents. Analyze the water soluble CPM in Container 1 as
described in this section. Place the contents of Container
1 into a separatory funnel. Add approximately 30 ml of
hexane to the funnel, mix well, and pour off the upper organic
phase. Repeat this procedure twice with 30 ml of hexane each time
combining the organic phase from each extraction. Each time, leave a
small amount of the organic/hexane phase in the separatory funnel,
ensuring that no water is collected in the organic phase. This
extraction should yield about 90 ml of organic extract. Combine the
organic extract from Container 1 with the organic train
rinse in Container 2.

* * * * *
(h) Unless otherwise specified in the applicable subpart, each test
location must be verified to be free of cyclonic flow and evaluated for
the existence of emission gas stratification and the required number of
sampling traverse points. If other procedures are not specified in the
applicable subpart to the regulations, use the appropriate procedures
in Method 1 to check for cyclonic flow and Method 7E to evaluate
emission gas stratification and selection of sampling points.
(i) Whenever the use of multiple calibration gases is required by a
test method, performance specification, or quality assurance procedure
in a Part 60 standard or appendix, Method 205 of 40 CFR part 51,
Appendix M, ``Verification of Gas Dilution Systems for Field Instrument
Calibrations,'' may be used.
7. Amend Sec. 60.13 by revising paragraph (d)(1) to read as

(d)(1) Owners and operators of a CEMS installed in accordance with
the provisions of this part, must check the zero (or low level value
between 0 and 20 percent of span value) and span (50 to 100 percent of
span value) calibration drifts at least once daily in accordance with a
written procedure. The zero and span must, at a minimum, be adjusted
whenever either the 24-hour zero drift or the 24-hour span drift
exceeds two times the limit of the applicable performance specification
in Appendix B of this part. The system must allow the amount of the
excess zero and span drift to be recorded and quantified whenever
specified. Owners and operators of a COMS installed in accordance with
the provisions of this part must check the zero and upscale (span)
calibration drifts at least once daily. For a particular COMS, the
acceptable range of zero and upscale calibration materials is defined
in the applicable version of PS-1 in Appendix B of this part. For a
COMS, the optical surfaces, exposed to the effluent gases, must be
cleaned before performing the zero and upscale drift adjustments,
except for systems using automatic zero adjustments. The optical
surfaces must be cleaned when the cumulative automatic zero
compensation exceeds 4 percent opacity.

24. Amend Method 1 of Appendix A-1 to Part 60 by revising Sections
11.2.2, 11.4.1, and Figures 1-1 and 1-2 to read as follows:
Appendix A-1 to Part 60--Test Methods 1 Through 2F
Method 1--Sample and Velocity Traverses From Stationary Sources
* * * * *
11.2.2 Velocity and Gaseous (Non-Particulate) Traverses. Perform
a stratification test 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.
When the 8- and 2-diameter criterion can be met, the minimum number
of traverse points for the stratification test will be 12. Test for
stratification using a probe of appropriate length to measure the
gas concentration at the required traverse points located according
to Table 1-2. Alternatively (if the 8- and 2-diameter criterion is
met), you may measure the gas concentration 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 at each traverse point.
Calculate the individual point and mean 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
no 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 12-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, 1.0 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 12 traverse points for the test in accordance with Table 1-2.
* * * * *
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 scrubbers, or (2) in stacks having
tangential inlets or other duct configurations which tend to induce
swirling. Determine the presence or absence of cyclonic flow at each
sampling location. The following techniques are acceptable for this
determination.

Method 5--Determination of Particulate Matter Emissions From Stationary
Sources
* * * * *
6.1.1.5 Filter Holder. Borosilicate glass, with a glass frit
filter support and a silicone rubber gasket. Alternatively, Teflon
filter holders may be used. Other materials of construction (e.g.,
stainless steel or Viton) may be used, subject to the approval of
the Administrator. The holder design shall provide a positive seal
against leakage from the outside or around the filter. The holder
shall be attached immediately at the outlet of the probe (or
cyclone, if used).
* * * * *
6.1.1.7 Temperature Sensor. A calibrated temperature sensor
(rechecked at at least one point after each test) shall be installed
so that the sensing tip of the temperature sensor is in direct
contact with the sample gas, and the temperature around the filter
holder can be regulated and monitored during sampling.
* * * * *
6.1.1.9 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.
Alternatively, an Isostack metering system may be used if all Method
5 calibrations are performed, with the exception of those related to
[Delta]H@ in Section 9.2.1, wherein the sample flow rate system
shall be calibrated in lieu of [Delta]H@ and shall not deviate by
more than 5 percent. Other metering systems capable of maintaining
sampling rates within 10 percent of isokinetic and of determining
sample volumes to within 2 percent may be used, subject to the
approval of the Administrator. When the metering system is used in
conjunction with a pitot tube, the system shall allow periodic
checks of isokinetic rates.
* * * * *
7.1.3 Water. When analysis of the material caught in the
impingers is required, deionized distilled water (to conform to ASTM
D 1193-77 or 91 Type 3 (incorporated by reference--see Sec. 60.17))
with <= 0.001 percent residue shall be used. Run blanks prior to
field use to eliminate a high blank on test samples, and use only
water with low blank values (<= 0.001 percent).
* * * * *
8.1 Pretest Preparation. It is suggested that sampling equipment
be maintained according to the procedures described in APTD-0576.
Alternative mercury-free thermometers may be used if the
thermometers are at a minimum equivalent in terms of performance or
suitably effective for the specific temperature measurement
application.
* * * * *
8.3.4 Set up the train as shown in Figure 5-1 ensuring that the
connections are leak-tight. Subject to the approval of the
Administrator, a glass cyclone may be used between the probe and
filter holder when the total particulate catch is expected to exceed
100 mg or when water droplets are present in the stack gas.
* * * * *
8.7.3 Before moving the sample train to the cleanup site, remove
the probe from the sample train and cap the open outlet of the
probe. Be careful not to lose any condensate that might be present.
Cap the filter inlet where the probe was fastened. Remove the
umbilical cord from the last impinger, and cap the impinger. If a
flexible line is used between the first impinger or condenser and
the filter holder, disconnect the line at the filter holder, and let
any condensed water or liquid drain into the impingers or condenser.
Cap off the filter holder outlet and impinger inlet. Either ground-
glass stoppers, plastic caps, or serum caps may be used to close
these openings.
* * * * *
8.7.5 Save a portion of the acetone used for cleanup as a blank.
For each container of acetone used for cleanup, save 200 ml and
place it in a glass sample container labeled ``acetone blank.'' To
minimize any particulate contamination, rinse the wash bottle prior
to filling from the tested container. Take 200 ml of this acetone
directly from the wash bottle being used, and place it in a glass
sample container labeled ``acetone blank.''
* * * * *
10.3.3 Acceptable Variation in Calibration Check. If the DGM
coefficient values obtained before and after a test series differ by
more than 5 percent, the test series shall either be voided, or
calculations for the test series shall be performed using whichever
meter coefficient value (i.e., before or after) gives the lower
value of total sample volume.
* * * * *
10.4 Probe Heater Calibration. Use a heat source to generate air
heated to selected temperatures that approximate those expected to
occur in the sources to be sampled. Pass this air through the probe
at a typical sample flow rate while measuring the probe inlet and
outlet temperatures at various probe heater settings. For each air
temperature generated, construct a graph of probe heating system
setting versus probe outlet temperature. The procedure outlined in
APTD-0576 can also be used. Probes constructed according to APTD-
0581 need not be calibrated if the calibration curves in APTD-0576
are used. Also, probes with outlet temperature monitoring
capabilities do not require calibration. As an alternative, the
following single-point calibration procedure may be used. After each
test run series, check the accuracy (and, hence, the calibration) of
each thermocouple system at ambient temperature, or any other
temperature, within the range specified by the manufacturer, using a
reference thermometer (either ASTM reference thermometer or a
thermometer that has been calibrated against an ASTM reference
thermometer). The temperatures of the thermocouple and reference
thermometers shall agree to within 2 [deg]F. Note: The
probe heating system shall be calibrated before its initial use in
the field.
10.5 Temperature Sensors. Use the procedure in Section 10.3 of
Method 2 to calibrate in-stack temperature sensors. Dial
thermometers, such as are used for the DGM and condenser outlet,
shall be calibrated against mercury-in-glass thermometers. An
alternative mercury-free NIST-traceable thermometer may be used if
the thermometer is, at a minimum, equivalent in terms of performance
or suitably effective for the specific temperature measurement
application.
10.6 Barometer. Calibrate against a mercury barometer or NIST-
traceable barometer prior to the field test. Alternatively,
barometric pressure may be obtained from a weather report that has
been adjusted for the test point (on the stack) elevation.

16.3 Alternative Post-Test Metering System Calibration. The
following procedure may be used as an alternative to the post-test
calibration described in Section 10.3.2. This alternative procedure
does not detect leakages between the inlet of the metering system
and the dry gas meter. Therefore, two steps must be included to make
it an equivalent alternative: (1) The metering system must pass the
post-test leak-check from either the inlet of the sampling train or
the inlet of the metering system. Therefore, if the train fails the
former leak-check, another leak-check from the inlet of the metering
system must be conducted; (2) The metering system must pass the
leak-check of that portion of the train from the pump to the orifice
meter as described in Section 10.3.1.1.
16.3.1 After each test run, do the following:
16.3.1.1 Ensure that the metering system has passed the post-
test leak-check. If not, conduct a leak-check of the metering system
from its inlet.
16.3.1.2 Conduct the leak-check of that portion of the train
from the pump to the orifice meter as described in Section 10.3.1.1.
16.3.1.3 Calculate Yqa for each test run using the
following equation:
[GRAPHIC] [TIFF OMITTED] TP09JA12.036
Where:
Yqa = Dry gas meter calibration check value,
dimensionless.
0.0319 = (29.92/528)(0.75)\2\(in. Hg/[deg]R) cfm\2\.
[Delta]H@ = Orifice meter calibration coefficient, in.
H2O.
Md = Dry molecular weight of stack gas, lb/lb-mole.
29 = Dry molecular weight of air, lb/lb-mole.
16.3.2 After each test run series, do the following:
16.3.2.1 Average the three or more Yqa's obtained
from the test run series and compare this average Yqa
with the dry gas meter calibration factor Y. The average
Yqa must be within 5 percent of Y.
16.3.2.2 If the average Yqa does not meet the 5
percent criterion, recalibrate the meter over the full range of
orifice settings as detailed in Section 10.3.1. Then follow the
procedure in Section 10.3.3.

16.0 Alternative Procedures
16.1 Alternative Stack Gas Volumetric Flow Rate Determination
(Tracer Gas).
16.1.1 Apparatus.
16.1.1.1 Tracer Gas Injector System. This is to inject a known
concentration of tracer gas into the stack. This system consists of
a cylinder of tracer gas, a gas cylinder
[[Page 1155]]
regulator, a stainless steel needle valve or a flow controller, a
nonreactive (stainless steel or glass) rotameter, and an injection
loop to disperse the tracer gas evenly in the stack.
16.1.1.2 Tracer Gas Probe. A glass or stainless steel sampling
probe.
16.1.1.3 Gas Conditioning System. A gas conditioning is a system
suitable for delivering a cleaned sample to the analyzer consisting
of a filter to remove particulate and a condenser capable of
lowering the dew point of the sample gas to less than 5 [deg]C (40
[deg]F). A desiccant such as anhydrous calcium sulfate may be used
to dry the sample gas. Desiccants which react or absorb tracer gas
or stack gas may not be used, e.g. silica gel absorbs
CO2.
16.1.1.4 Pump. An inert (i.e., stainless steel or Teflon head)
pump to deliver more than the total sample required by the
manufacturer's specifications for the analyzer used to measure the
downstream tracer gas concentration.
16.1.1.5 Gas Analyzer. A gas analyzer is any analyzer capable of
measuring the tracer gas concentration in the range necessary at
least every 10 minutes. A means of controlling the analyzer flow
rate and a device for determining proper sample flow rate shall be
provided unless data is provided to show that the analyzer is
insensitive to flow variations over the range encountered during the
test. The gas analyzer needs to meet or exceed the flowing
performance specifications:
------------------------------------------------------------------------
------------------------------------------------------------------------
Linearity.......................... 1 percent of full
scale.
Calibration Error.................. <= 2 percent of span.
Response Time...................... <= 10 seconds.
Zero Drift (24 hour)............... <= 2 percent of full scale.
Span Drift (24 hour)............... <= 2 percent of full scale.
Resolution......................... <= 0.5 percent of span.
------------------------------------------------------------------------
16.1.1.6 Recorder (optional). To provide a permanent record of
the analyzer output.
16.1.2 Reagents.
16.1.2.1 Tracer Gas. The tracer gas is sulfur hexafluoride in an
appropriate concentration for accurate analyzer measurement or pure
sulfur dioxide. The gas used must be nonreactive with the stack
effluent and give minimal (< 3 percent) interference to measurement
by the gas analyzer.
16.1.3 Procedure. Select upstream and downstream locations in
the stack or duct for introducing the tracer gas and delivering the
sampled gas to the analyzer. The inlet location should be 8 or more
duct diameters beyond any upstream flow disturbance. The outlet
should be 8 or more undisturbed duct diameters from the inlet and 2
or more duct diameters from the duct exit. After installing the
apparatus, meter a known concentration of the tracer gas into the
stack at the inlet location. Use the gas sample probe and analyzer
to show that no stratification of the tracer gas is found in the
stack at the measurement locations. Monitor the tracer gas
concentration from the outlet location and record the concentration
at 10-minute intervals or more often at the option of the tester. A
minimum of three measured intervals is recommended to determine the
stack gas volumetric flow rate. Other statistical procedures may be
applied for complete flow characterization and additional QA/QC.

located, unmodified Method 6 sampling train. Quenching in
fluorescence analyzers must be evaluated and remedied unless a
dilution system and ambient-level analyzer is used. This may be done

Biased results have been observed when sampling under conditions
of high sulfur dioxide concentrations. At or above 2100 ppm

concentration of the Method 7 absorbing solution. Laboratory tests
have shown that high concentrations of SO2 (about 2100

6.1 What do I need for the measurement system? You may use any
equipment and supplies meeting the following specifications:
(1) Sampling system components that are not evaluated in the
system bias or system calibration error test must be glass, Teflon,
or stainless steel. Other materials are potentially acceptable,
subject to approval by the Administrator.
(2) The interference, calibration error, and system bias
criteria must be met.
[[Page 1156]]
(3) Sample flow rate must be maintained within 10 percent of the
flow rate at which the system response time was measured.
(4) All system components (excluding sample conditioning
components, if used) must maintain the sample temperature above the
moisture dew point. Ensure minimal contact between any condensate
and the sample gas. Section 6.2 provides example equipment
specifications for a NOX measurement system. Figure 7E-1
is a diagram of an example dry-basis measurement system that is
likely to meet the method requirements and is provided as guidance.
For wet-basis systems, you may use alternative equipment and
supplies as needed (some of which are described in Section 6.2),
provided that the measurement system meets the applicable
performance specifications of this method.
* * * * *
7.1.1 High-Level Gas. This concentration is chosen to set the
calibration span as defined in Section 3.4. Choose this high-level
concentration so that emission measurements will be within 20 to 100
percent of this concentration.
* * * * *
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 12 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 no 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 12-point stratification test
was performed and the emissions 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 12 traverse points for the test in
accordance with Table 1-1 or Table 1-2 of Method 1. This
stratification test may not be meaningful at sources with temporally
varying emissions or where emission concentrations are low. In these
cases, the stratification test is not required.
* * * * *
8.2.5 Initial System Bias and System Calibration Error Checks.
Before sampling begins, determine whether the high-level or mid-
level calibration gas best approximates the emissions and use it as
the upscale gas. Introduce the upscale gas at the probe upstream of
all sample conditioning components in system calibration mode.
Record the time it takes for the measured concentration to increase
to a value that is within 95 percent or 0.5 ppm (whichever is less
restrictive) of a stable response for both the low-level and upscale
gases. Continue to observe the gas concentration reading until it
has reached a final, stable value. Record this value on a form
similar to Table 7E-2.
* * * * *
16.2.2 Bag Procedure. Perform the analyzer calibration error
test to document the calibration (both NO and NOX modes,
as applicable). Fill a Tedlar or equivalent bag approximately half
full with either ambient air, pure oxygen, or an oxygen standard gas
with at least 19.5 percent by volume oxygen content. Fill the
remainder of the bag with mid- to high-level NO in N2 (or
other appropriate concentration) calibration gas. (Note that the
concentration of the NO standard should be sufficiently high enough
for the diluted concentration to be easily and accurately measured
on the scale used. The size of the bag should be large enough to
accommodate the procedure and time required. Contact the bag
manufacturer for guidance on the applicability of Tedlar equivalent
materials for NO.)

of this solution into a 250-ml Erlenmeyer flask, add 2 to 4 drops of
thorin indicator, and titrate to a pink endpoint using 0.0100 N

using by evacuating with a pump followed by a dry gas meter. When
the evacuation is complete, there should be no flow through the
meter. Gas tanks may be used in place of bags if the samples are
analyzed within one week.

8.4.2 Integrated Sampling. Evacuate the flexible bag. 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

2.0 Summary of Method
An integrated gas sample is extracted from the stack, passed
through an alkaline permanganate solution to remove sulfur oxides
and nitrogen oxides, and collected in a Tedlar or equivalent bag.
(Contact the bag manufacturer for guidance on the applicability of
Tedlar equivalent materials for the compound of interest.) The CO
concentration in the sample is measured spectrophotometrically using
the reaction of CO with p-sulfaminobenzoic acid.
* * * * *
8.2.1 Evacuate the bag completely using a vacuum pump. 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 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 to the system,
[[Page 1158]]
record the starting time, and sample at a rate of 300 ml/min for 30
minutes, or until the bag is nearly full. Record the sampling time,
the barometric pressure, and the ambient temperature. Purge the
system as described above immediately before each sample.
* * * * *
11.1 Assemble the system shown in Figure 10A-3, and record the
information required in Table 10A-1 as it is obtained. Pipet 10.0 ml
of the colorimetric reagent into each gas reaction bulb, and attach
the bulbs to the system. Open the stopcocks to the reaction bulbs,
but leave the valve to the bag closed. Turn on the pump, fully open
the coarse-adjust flow valve, and slowly open the fine-adjust valve
until the pressure is reduced to at least 40 mm Hg. Now close the
coarse adjust valve, and observe the manometer to be certain that
the system is leak-free. Wait a minimum of 2 minutes. If the
pressure has increased less than 1 mm Hg, proceed as described
below. If a leak is present, find and correct it before proceeding
further.
11.2 Record the vacuum pressure (Pv) to the nearest 1
mm Hg, and close the reaction bulb stopcocks. Open the bag valve,
and allow the system to come to atmospheric pressure. Close the bag
valve, open the pump coarse adjust valve, and evacuate the system
again. Repeat this fill/evacuation procedure at least twice to flush
the manifold completely. Close the pump coarse adjust valve, open
the bag valve, and let the system fill to atmospheric pressure. Open
the stopcocks to the reaction bulbs, and let the entire system come
to atmospheric pressure. Close the bulb stopcocks, remove the bulbs,
record the room temperature and barometric pressure
(Pbar, to nearest mm Hg), and place the bulbs on the
shaker table with their main axis either parallel to or
perpendicular to the plane of the table top. Purge the bulb-filling
system with ambient air for several minutes between samples. Shake
the samples for exactly 2 hours.
* * * * *
12.3 CO Concentration in the Bag. Calculate Cb using
Equations 10A-2 and 10A-3. If condensate is visible in the bag,
calculate Bw using Table 10A-2 and the temperature and
barometric pressure in the analysis room. If condensate is not
visible, calculate Bw using the temperature and
barometric pressure at the sampling site. * * *
* * * * *
13.5 Stability. The individual components of the colorimetric
reagent are stable for at least one month. The colorimetric reagent
must be used within two days after preparation to avoid excessive
blank correction. The samples in the bag should be stable for at
least one week if the bags are leak-free.
* * * * *

Sections 2.1 and 6.2.3, and by revising the narrative in Section 12.2

2.1 An integrated gas sample is extracted from the sampling
point, passed through a conditioning system to remove interferences,
and collected in a Tedlar or equivalent bag. (Contact the bag
manufacturer for guidance on the applicability of Tedlar equivalent
materials for the compound of interest.) The CO is separated from
the sample by gas chromatography (GC) and catalytically reduced to
methane (CH4) which is determined by flame ionization
detection (FID). The analytical portion of this method is identical
to applicable sections in Method 25 detailing CO measurement.
* * * * *

6.3.1.4, equipped to accept a sample line from the bag.

Equations 10B-1 and 10B-2. If condensate is visible in the bag,

temperature and barometric pressure in the analysis room. If
condensate is not visible, calculate Bw using the
temperature and barometric pressure at the sampling site. * * *

depletion of the absorbing solution. An additional cadmium sulfate
impinger should be added for subsequent samples and the sample with

and inside of the filter holder as specified by Method 5, (2) 0.1 N
HNO3 is used in the impingers, (3) a glass fiber filter
with a low Pb background is used, and (4) the entire train contents,

16.4 Alternative Analyzer. Inductively coupled plasma-atomic
emission spectrometry (ICP-AES) may be used as an alternative to
atomic absorption analysis provided the following conditions are
met:
16.4.1 Sample collection, sample preparation, and analytical
preparation procedures are as defined in the method except as
necessary for the ICP-AES application.
16.4.2 The limit of quantitation for the ICP-AES must be
demonstrated, and the sample concentrations reported should be no
less than two times the limit of quantitation. The limit of
quantitation is defined as ten times the standard deviation of the
blank value. The standard deviation of the blank value is determined
from the analysis of seven blanks. It has been reported that for
mercury and those elements that form hydrides, a continuous-flow
generator coupled to an ICP-AES offers detection limits comparable
to cold vapor atomic absorption.

8.2.1.1.2 Sampling Procedure. To obtain a sample, assemble the
sample train as shown in Figure 18-9. Leak-check both the bag and
the container. Connect the vacuum line from the needle valve to the
Teflon sample line from the probe. Place the end of the probe at the
centroid of the stack or at a point no closer to the walls than 1 m,
and start the pump. Set the flow rate so that the final volume of
the sample is approximately 80 percent of the bag capacity. After
allowing sufficient time to purge the line several times, connect
the vacuum line to the bag, and evacuate until the rotameter
indicates no flow. Then position the sample and vacuum lines for
sampling, and begin the actual sampling, keeping the rate
proportional to the stack velocity. As a precaution, direct the gas
exiting the rotameter away from sampling personnel. At the end of
the sample period, shut off the pump, disconnect the sample line
from the bag, and disconnect the vacuum line from the bag container.
Record the source temperature, barometric pressure, ambient
temperature, sampling flow rate, and initial and final sampling time
on the data sheet shown in Figure 18-10. Protect the bag and its
container from sunlight. Record the time lapsed between sample
collection and analysis, and then conduct the recovery procedure in
Section 8.4.2.
* * * * *
8.2.1.4 Other Modified Bag Sampling Procedures. In the event
that condensation is observed in the bag while collecting the sample
and a direct interface system cannot be used, heat the bag during
collection and maintain it at a suitably elevated temperature during
all subsequent operations. (Note: Take care to leak-check the system
prior to the dilutions so as not to create a potentially explosive
atmosphere.) As an alternative, collect the sample gas, and
simultaneously dilute it in the bag.
* * * * *
8.2.1.4.2 Second Alternative Procedure. Prefill the bag with a
known quantity of inert gas. Meter the inert gas into the bag
according to the procedure for the preparation of gas concentration
standards of volatile liquid materials (Section 10.1.2.2), but
eliminate the midget impinger section. Take the partly filled bag to
the source, and meter the source gas into the bag through heated
sampling lines and a heated flowmeter, or Teflon positive
displacement pump. Verify the dilution factors before sampling each
bag through dilution and analysis of gases of known concentration.
* * * * *
8.2.1.5.2.2 Analyze the two field audit samples as described in
Section 9.2 by connecting each bag containing an audit gas mixture
to the sampling valve. Calculate the results; record and report the
data to the audit supervisor.
* * * * *
16.1.1.12 Flexible Bags. Tedlar or equivalent, 10- and 50-liter
capacity, for preparation of standards. (Contact the bag
manufacturer for guidance on the applicability of Tedlar equivalent
materials for the compound of interest.)
* * * * *
16.1.3.2 Flexible Bag Procedure. Any leak-free plastic (e.g.,
Tedlar, Mylar, Teflon) or plastic-coated aluminum (e.g., aluminized
Mylar) bag, or equivalent, can be used to obtain the pre-survey
sample. Use new bags, and leak-check them before field use. In
addition, check the bag before use for contamination by filling it
with nitrogen or air and analyzing the gas by GC at high
sensitivity. Experience indicates that it is desirable to allow the
inert gas to remain in the bag about 24 hours or longer to check for
desorption of organics from the bag. Follow the leak-check and
sample collection procedures given in Section 8.2.1.

I.D. with a heating system capable of maintaining a probe gas
temperature during sampling of 120 14 [deg]C (248
25 [deg]F) to prevent moisture condensation; or Teflon
where stack probes are below 210 [deg]C. If HF is a target analyte,
then preconditioning of new teflon components by heating should be
considered to prevent potential HF outgassing. A Teflon-glass filter
in a mat configuration should be installed in the gas stream, not
the filter box, to remove particulate matter from the gas stream
(see Section 6.1.6).
* * * * *
8.1.2 Adjust the probe temperature and the temperature of the
filter and the stopcock (i.e., the heated area in Figure 26-1) to a
temperature sufficient to prevent water condensation. This
temperature should be greater than 120 [deg]C (248 [deg]F). The
temperature should be monitored throughout a sampling run to ensure
that the desired temperature is maintained. It is important to
maintain a temperature around the probe and filter of greater than
120 [deg]C (248 [deg]F) 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 would result in potential underreporting of these
emissions. The applicable subparts may specify alternative higher
temperatures.)

* * * * *
11.3 Field Sample Analyses. Analyze the sorbent trap samples
following the same procedures that were used for conducting the
Hg\0\ and HgCl2 analytical bias tests. The individual
sections of the sorbent trap and their respective components must be
analyzed separately (i.e., section 1 and its components, then
section 2 and its components). All sorbent trap section 1 sample
analyses must be within the calibrated range of the analytical
system as specified in Table 9-1. For wet analyses, the sample can
simply be diluted to fall within the calibrated range. However, for
the destructive thermal analyses, samples that are not within the
calibrated range cannot be re-analyzed. As a result, the sample
cannot be validated, and another sample must be collected. It is
strongly suggested that the analytical system be calibrated over
multiple ranges so that thermally analyzed samples do fall within
the calibrated range. The total mass of Hg measured in each sorbent
trap section 1 must also fall within the lower and upper mass limits
established during the initial Hg\0\ and HgCl2 analytical
bias test. If a sample is analyzed and found to fall outside of
these limits, it is acceptable for an additional Hg\0\ and
HgCl2 analytical bias test to be performed that now
includes this level. However, some samples (e.g., the mass collected
in trap section 2), may have Hg levels so low that it may not be
possible to quantify them in the analytical system's calibrated
range. Because a reliable estimate of these low-level Hg
measurements is necessary to fully validate the emissions data, the
MDL (see section 8.2.2.1 of this method) is used to establish the
minimum amount that can be detected and reported. If the measured
mass or concentration is below the lowest point in the calibration
curve and above the MDL, the analyst must do the following: Estimate
the mass or concentration of the sample based on the analytical
instrument response relative to an additional calibration standard
at a concentration or mass between the MDL and the lowest point in
the calibration curve. This is accomplished by establishing a
response factor (e.g., area counts per Hg mass or concentration) and
estimating the amount of Hg present in the sample based on the
analytical response and this response factor. * * *

11.1.1.4.3 Continuous Emission Monitors as RMs. If the RM is a
CEM, synchronize the sampling flow rates of the RM and the FTIR CEM.
Each run is at least 1 hour long and consists of at least 10 FTIR
CEM measurements and the corresponding 10 RM measurements (or
averages). For the statistical comparison, use the relative accuracy
analysis procedure in Performance Specification 2 of Appendix B of
40 CFR part 60. If the RM time constant is < \1/2\ the FTIR CEM time
constant, brief fluctuations in analyte concentrations that are not
adequately measured with the slower FTIR CEM time constant can be
excluded from the run average along with the corresponding RM
measurements. However, the FTIR CEM run average must still include
at least 10 measurements over a 1-hour period.

6.1.7 Sensor Location and Repair. We recommend you install
sensors in an accessible location in order to perform repairs and
replacements. Permanently-installed platforms or ladders may not be
needed. If you install sensors in an area that is not accessible,
you may be required to shut down the emissions unit to repair or
replace a sensor. Conduct a new RATA after replacing a sensor that
supplies a critical PEMS parameter if the new sensor provides a
different output or scaling or changes the historical training
dataset of the PEMS. Replacement of a non-critical sensor that does
not cause an impact in the accuracy of the PEMS does not trigger a
RATA. All sensors must be calibrated as often as needed but at least
as often as recommended by the manufacturers.
* * * * *
8.2.1 Reference Methods. Unless otherwise specified in the
applicable regulations, you must use the test methods in Appendix A
of this part for the RM test. Conduct the RM tests at three
operating levels. The RM tests shall be performed at a low-load (or
production) level between the minimum safe, stable load and 50
percent of the maximum level load, at the mid-load level (an
intermediary level between the low and high levels), and at a high-
load level between 80 percent and the maximum load. Alternatively,
if practicable, you may test at three levels of the key operating
parameter (e.g. selected based on a covariance analysis between each
parameter and the PEMS output) equally spaced within the normal
range of the parameter.

9.3 Quarterly Relative Accuracy Audits. In the first year of
operation after the initial certification, perform a RAA consisting
of at least three 30-minute portable analyzer or RM determinations
each quarter a RATA is not performed. To conduct a RAA, follow the
procedures in Section 8.2 for the relative accuracy test, except
that only three sets of measurement data are required, and the
statistical tests are not required. The average of the three or more
portable analyzer or RM determinations must not exceed the limits
given in Section 13.5. Report the data from all sets of measurement
data. If a PEMS passes all quarterly RAAs in the first year and also
passes the subsequent yearly RATA in the second year, you may elect
to perform a single mid-year RAA in the second year in place of the
quarterly RAAs. This option may be repeated, but only until the PEMS
fails either a mid-year RAA or a yearly RATA. When such a failure
occurs, you must resume quarterly RAAs in the quarter following the
failure and continue conducting quarterly RAAs until the PEMS
successfully passes both a year of quarterly RAAs and a subsequent
RATA.
9.4 Yearly Relative Accuracy Test. Perform a minimum 9-run RATA
at the normal operating level on a yearly basis in the quarter that
the RAA is not performed. The statistical tests in Section 8.3 are
not required for the yearly RATA.
* * * * *
12.4 Relative Accuracy Audit. Calculate the quarterly RAA using
Equation 16-9.
[GRAPHIC] [TIFF OMITTED] TP09JA12.042
* * * * *
13.5 Relative Accuracy Audits. The average of the three portable
analyzer or RM determinations must not differ from the simultaneous
PEMS average value by more than 10 percent of the analyzer or RM for
concentrations greater than 100 ppm or 20 percent for concentrations
between 100 and 20 ppm, or the test is failed. For measurements at
20 ppm or less, this difference must not exceed 2 ppm for a
pollutant PEMS and 1 percent absolute for a diluents PEMS.

CEMS (e.g., dscm),
VR = Sample gas volume measured by the independent
calibrated reference device (e.g., dscm) for the SVA or the
reference value for the daily sample volume check.
Note: Before calculating SVA accuracy, you must correct the
sample gas volumes measured by your PM CEMS and the independent
calibrated reference device to the same basis of temperature,
pressure, and moisture content. You must document all data and
calculations.

follows:
Sec. 61.13 Emission tests and waiver of emission tests.
* * * * *
(e) * * *
(1) * * *
(i) 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; Methods 6C, 7E, 9, and 10 of
Appendix A-4 of Part 60; Method 18 and 19 of Appendix A-6 of Part 60;
Methods 20, 22, and 25A of Appendix A-7 of Part 60; and Methods 303,
318, 320, and 321 of Appendix A of Part 63. 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,
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 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.

shall test emissions from the source according to Method 104 of
Appendix B to this part or according to Method 29 of Appendix A to Part
60. Method 103 of Appendix B to this part is approved by the
Administrator as an alternative method for sources subject to Sec.
61.32(a). The emission test shall be performed:
(1) Within 90 days of the effective date in the case of an existing
source or a new source which has an initial startup date preceding the
effective date; or
(2) Within 90 days of startup in the case of a new source which did
not have an initial startup date preceding the effective date.
* * * * *
71. Amend Sec. 61.42 by revising paragraph (a) to read as follows:

4.1 Matrix Effects. Analysis for Be by flame atomic absorption
spectrophotometry is sensitive to the chemical composition and to
the physical properties (e.g., viscosity, pH) of the sample.
Aluminum and silicon, in particular, are known to interfere when
present in appreciable quantities. The analytical procedure includes
(optionally) the use of the Method of Standard Additions to check
for these matrix effects, and sample analysis using the Method of
Standard Additions if significant matrix effects are found to be
present (see Reference 2 in Section 17.0).
* * * * *
11.5.3 Check for Matrix Effects (optional). Use the Method of
Standard Additions (see Reference 2 in Section 17.0) to check at
least one sample from each source for matrix effects on the Be
results. If the results of the Method of Standard Additions
procedure used on the single source sample do not agree to within 5
percent of the value obtained by the routine atomic absorption
analysis, then reanalyze all samples from the source using the
Method of Standard Additions procedure.

part, to meet or exceed the efficiency data points found in Tables 1
and 2, or 3 and 4 of Sec. 63.745 for existing or new sources
respectively.
89. Amend Sec. 63.1251 by revising the definition of ``Process
vent'' to read as follows:
Sec. 63.1251 Definitions.
* * * * *
Process vent means a vent from a unit operation or vents from
multiple unit operations within a process that are manifolded together
into a common header, through which a HAP-containing gas stream is, or
has the potential to be, released to the atmosphere. Examples of
process vents include, but are not limited to, vents on condensers used
for product recovery, bottom receivers, surge control vessels,
reactors, filters, centrifuges, and process tanks. Emission streams
that are undiluted and uncontrolled containing less than 50 ppmv HAP,
as determined through process knowledge that no HAP are present in the
emission stream or using an engineering assessment as discussed in
Sec. 63.1257(d)(2)(ii); test data using Method 18 of 40 CFR part 60,
Appendix A; Method 320 of 40 CFR part 63; or any other test method that
has been validated according to the procedures in Method 301 of
Appendix A of this part, are not considered process vents. Process
vents do not include vents on storage tanks regulated under Sec.
63.1253, vents on wastewater emission sources regulated under Sec.
63.1256, or pieces of equipment regulated under Sec. 63.1255.
* * * * *
90. Amend Sec. 63.1511 by revising paragraph (c)(9) as to read
follows:
Sec. 63.1511 Performance test/compliance demonstration general
requirements.
* * * * *
(c) * * *
(9) Method 26A for the concentration of HCl. Where a lime-injected
fabric filter is used as the control device to comply with the 90
percent reduction standard, the owner or operator must measure the
fabric filter inlet concentration of HCl at a point before lime is
introduced to the system. Method 26 may be used in place of Method 26A
where it can be demonstrated that there are no water droplets in the
emission stream. This can be demonstrated by showing that the vapor
pressure of water in the emission stream that you are testing is less
than the equilibrium vapor pressure of water at the emission stream
temperature, and by certifying that the emission stream is not
controlled by a wet scrubber.

94. Amend Method 306 of Appendix A to Part 63 by revising Sections
2.2.1, 6.1.4, and 8.0 to read as follows:
Appendix A to Part 63--Test Methods Pollutant Measurement Methods From
Various Waste Media
* * * * *
Method 306--Determination of Chromium Emissions From Decorative and
Hard Chromium Electroplating and Chromium Anodizing Operations--
Isokinetic Method
* * * * *
2.2.1 Total chromium samples with high chromium concentrations
(>=35 [micro]g/L) may be analyzed using inductively coupled plasma
emission spectrometry (ICP) at 267.72 nm. Note: The ICP analysis is
applicable for this method only when the solution analyzed has a Cr
concentration greater than or equal to 35 [micro]g/L or five times
the method detection limit as determined according to Appendix B in
40 CFR part 136. Similarly, inductively coupled plasma-mass
spectroscopy (ICP-MS) may be used for total chromium analysis
provided the procedures for ICP-MS analysis described in Method 6020
or 6020A (EPA Office of Solid Waste, publication SW-846) are
followed.
* * * * *
6.1.4 Operating and maintenance procedures for the sampling
train are described in APTD-0576 of Method 5. Users should read the
APTD-0576 document and adopt the outlined procedures. Alternative
mercury-free thermometers may be used if the thermometers are, at a
minimum, equivalent in terms of performance or suitably effective
for the specific temperature measurement application.
* * * * *
8.0 Sample Collection, Preservation, Holding Times, Storage, and
Transport
Note: Prior to sample collection, consideration should be given
to the type of analysis (Cr \+6\ or total Cr) that will be
performed. Which analysis option(s) will be performed will determine
which sample recovery and storage procedures will be required to
process the sample.
* * * * *
95. Amend Method 306A of Appendix A to Part 63 by revising Section
8.2 to read as follows:
Method 306A--Determination of Chromium Emissions From Decorative and
Hard Chromium Electroplating and Chromium Anodizing Operations
* * * * *
8.2 Sample Recovery. After the train has been transferred to the
sample recovery area, disconnect the tubing that connects the jar/
impingers. The tester shall select either the total Cr or Cr \+6\
sample recovery option. Samples to be analyzed for both total Cr and
Cr \+6\ shall be recovered using the Cr \+6\ sample option (Section
8.2.2). Note: Collect a reagent blank sample for each of the total
Cr or the Cr \+6\ analytical options. If both analyses (Cr and Cr
\+6\) are to be conducted on the samples, collect separate reagent
blanks for each analysis. Also, since particulate matter is not
usually present at chromium electroplating and/or chromium anodizing
operations, it is not necessary to filter the Cr \+6\ samples unless
there is observed sediment in the collected solutions. If it is
necessary to filter the Cr \+6\ solutions, please refer to Method
0061, Determination of Hexavalent Chromium Emissions from Stationary
Sources, Section 7.4, Sample Preparation in SW-846 (see Reference
1).

10.1.3 Temperature Sensors. Calibrate against mercury-in-glass
thermometers. An alternative mercury-free thermometer may be used if
the thermometer is, at a minimum, equivalent in terms of performance
or suitably effective for the specific temperature measurement
application.
* * * * *
97. Amend Method 315 of Appendix A to Part 63 by revising Sections
6.1.1 and 10.5 and by redesignating Section 8.11 as 8.1 and revising
newly designated section 8.1 to read as follows:

6.1.1 Sampling train. A schematic of the sampling train used in
this method is shown in Figure 5-1, Method 5, 40 CFR part 60,
Appendix A. Complete construction details are given in APTD-0581
(Reference 2 in section 17.0 of this method); commercial models of
this train are also available. For changes from APTD-0581 and for
allowable modifications of the train shown in Figure 5-1, Method 5,
40 CFR part 60, Appendix A, see the following subsections. Note: The
operating and maintenance procedures for the sampling train are
described in APTD-0576 (Reference 3 in section 17.0 of this method).
Since correct usage is important in obtaining valid results, all
users should read APTD-0576 and adopt the operating and maintenance
procedures outlined in it, unless otherwise specified herein.
Alternative mercury-free thermometers may be used if the
thermometers are, at a minimum, equivalent in terms of performance
or suitably effective for the specific temperature measurement
application. The use of grease for sealing sampling train components
is not recommended because many greases are soluble in methylene
chloride. The sampling train consists of the following components:

Method 2, 40 CFR part 60, Appendix A to calibrate in-stack
temperature sensors. Dial thermometers, such as are used for the DGM
and condenser outlet, shall be calibrated against mercury-in-glass
thermometers. An alternative mercury-free thermometer may be used if
the thermometer is, at a minimum, equivalent in terms of performance
or suitably effective for the specific temperature measurement
application.
