Revisions to Test Methods and Testing Regulations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: This action proposes editorial and technical corrections 
necessary for source testing of emissions and operations. The revisions 
include the addition of alternative equipment and methods as well as 
corrections to technical and typographical errors. We also solicit 
public comment on potential changes to the current procedures for 
determining emission stratification.

DATES: Comments must be received on or before March 9, 2012.
    Public Hearing. If anyone contacts the EPA by January 19, 2012 
requesting to speak at a public hearing, a hearing will be held on 
February 8, 2012.

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.

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

    In addition to being available in the docket, an electronic copy of 
this proposed rule will also be available on the Worldwide Web (WWW) 
through the Technology Transfer Network (TTN). Following signature, a 
copy of

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.

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 
and does not cause emission increases from regulated sources.

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.

PART 60--STANDARDS OF PERFORMANCE FOR NEW STATIONARY SOURCES

    5. The authority citation for part 60 continues to read as follows:

    Authority:  42 U.S.C. 7401, et seq.

    6. Amend Sec.  60.8 by revising paragraph (g)(1) and adding new 
paragraphs (h) and (i) to read as follows:

Sec.  60.8  Performance tests.

* * * * *
    (g) * * *
    (1) 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, 
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,

[[Page 1145]]

operator, or representative shall give the sample provider an estimate 
for the concentration of each pollutant that is emitted by the source 
or the estimated concentration of each pollutant based on the permitted 
level and the name, address, and phone number of the compliance 
authority. The source owner, operator, or representative shall report 
the results for the audit sample along with a summary of the emission 
test results for the audited pollutant to the compliance authority and 
shall report the results of the audit sample to the AASP. The source 
owner, operator, or representative shall make both reports at the same 
time and in the same manner or shall report to the compliance authority 
first and then report to the AASP. If the method being audited is a 
method that allows the samples to be analyzed in the field and the 
tester plans to analyze the samples in the field, the tester may 
analyze the audit samples prior to collecting the emission samples 
provided a representative of the compliance authority is present at the 
testing site. The tester may request, and the compliance authority may 
grant, a waiver to the requirement that a representative of the 
compliance authority must be present at the testing site during the 
field analysis of an audit sample. The source owner, operator, or 
representative may report the results of the audit sample to the 
compliance authority and 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.
* * * * *
    (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 
follows:

Sec.  60.13  Monitoring requirements.

* * * * *
    (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.
* * * * *
    8. Amend Sec.  60.17 by revising paragraphs (e) and (e)(1) to read 
as follows:

Sec.  60.17  Incorporations by reference.

* * * * *
    (e) The following material is available for purchase from the Water 
Environment Federation, 2626 Pennsylvania Avenue NW., Washington, DC 
20037.
    (1) Method 209A, Total Residue Dried at 103-105 [deg]C, in Standard 
Methods for the Examination of Water and Wastewater, 20th Edition,

for particulate matter and nitrogen oxides.

* * * * *
    (f) * * *
    (1) * * *
    (ii) Method 7E of Appendix A of this part or Method 320 of Appendix 
A of Part 63 shall be used to determine the NOX 
concentrations. Method 3A or 3B of Appendix A of this part shall be 
used to determine O2 concentration.
* * * * *
    (h) * * *
    (1) Conduct an initial performance test as required under Sec.  
60.8 over a minimum of 24 consecutive steam generating unit operating 
hours at maximum heat input capacity to demonstrate compliance with the 
NOX emission standards under Sec.  60.44b using Method 7, 
7A, or 7E of Appendix A of this part, Method 320 of Appendix A of Part 
63, or other approved reference methods; and
    (2) Conduct subsequent performance tests once per calendar year or 
every 400 hours of operation (whichever comes first) to demonstrate 
compliance with the NOX emission standards under Sec.  
60.44b over a minimum of 3 consecutive steam generating unit operating 
hours at maximum heat input capacity using Method 7, 7A, or 7E of 
Appendix A of this part, Method 320 of Appendix A of Part 63, or other 
approved reference methods.

* * * * *
    (b) * * *
    (2) Measuring SO2 according to Method 6B of Appendix A 
of this part at the inlet or outlet to the SO2 control 
system. An initial stratification test is required to verify the 
adequacy of the sampling location for Method 6B of Appendix A of this 
part. The stratification test shall consist of three paired runs of a 
suitable SO2 and CO2 measurement train operated 
at the candidate location and a second similar train operated according 
to the procedures in Section 3.2 and the applicable procedures in 
Section 7 of Performance Specification 2. Method 6B of Appendix A of 
this part, Method 6A of Appendix A of this part, or a combination of 
Methods 6 and 3 or 3B of Appendix A of this part or Methods 6C or 
Method 320 of Appendix A of Part 63 and 3A of Appendix A of this part 
are suitable measurement techniques. If Method 6B of Appendix A of this 
part is used for the second train, sampling time and timer operation 
may be adjusted for the stratification test as long as an adequate 
sample volume is collected; however, both sampling trains are to be 
operated similarly. For the location to be adequate for Method 6B of 
Appendix A of this part, 24-hour tests, the mean of the absolute

[[Page 1146]]

difference between the three paired runs must be less than 10 percent.
* * * * *
    11. Amend Sec.  60.51c by revising the definition of ``Medical/
infectious waste'' to read as follows:

Sec.  60.51c  Definitions.

* * * * *
    Medical/infectious waste means any waste generated in the 
diagnosis, treatment, or immunization of human beings or animals, in 
research pertaining thereto, or in the production or testing of 
biologicals that are listed in paragraphs (1) through (7) of this 
definition. The definition of medical/infectious waste does not include 
hazardous waste identified or listed under the regulations in part 261 
of this chapter; household waste, as defined in Sec.  261.4(b)(1) of 
this chapter; ash from incineration of medical/infectious waste, once 
the incineration process has been completed; human corpses, remains, 
and anatomical parts that are intended for interment or cremation; and 
domestic sewage materials identified in Sec.  261.4(a)(1) of this 
chapter.
* * * * *
    12. Amend Sec.  60.84 by revising the equation in paragraph (d) to 
read as follows:

    (2) Method 9 and the procedures in Sec.  60.11 shall be used to 
determine opacity from stack emissions and process fugitive emissions. 
The observer shall read opacity only when emissions are clearly 
identified as emanating solely from the affected facility being 
observed. 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. This option is subject to the 
following limitations:
    (i) No more than three emission points are read concurrently;
    (ii) All three emission points must be within a 70[deg] viewing 
sector or angle in front of the observer such that the proper sun 
position can be maintained for all three points; and
    (iii) If an opacity reading for any one of the three emission 
points is within 5 percent opacity of the application standard, then 
the observer must stop taking readings for the other two points and 
continue reading just that single point.

    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.

    8.1 Set up the apparatus as shown in Figure 2-1. Capillary 
tubing or surge tanks installed between the manometer and pitot tube 
may be used to dampen [Delta]P fluctuations. It is recommended, but 
not required, that a pretest leak-check be conducted as follows: (1) 
blow through the pitot impact opening until at least 7.6 cm (3.0 
in.) H2O velocity head registers on the manometer; then, 
close off the impact opening. The pressure shall remain stable 
( 2.5 mm H2O,  0.10 in. 
H2O) for at least 15 seconds; (2) do the same for the 
static pressure side, except using suction to obtain the minimum of 
7.6 cm (3.0 in.) H2O. Other leak-check procedures, 
subject to the approval of the Administrator, may be used.

constructed such that the impact pressure opening plane of the pitot 
tube is below the entry plane of the nozzle (see Figure 2-7B).

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.

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.

SO2, use five times the H2O2 
concentration of the Method 7 absorbing solution. Laboratory tests 
have shown that high concentrations of SO2 (about 2100 
ppm) cause low results in Method 7 and 7A. Increasing the

    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.

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.)

H2SO4 concentration, pipette a 10-ml aliquot 
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

compound of interest.) Leak-test the bag in the laboratory before 
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.

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 
tank is used for sample collection, follow procedures similar to 
those in Sections 8.1.2, 8.2.3, 8.3, and 12.4 of Method 25 as

Method 10A--Determination of Carbon Monoxide Emissions in Certifying 
Continuous Emission Monitoring Systems at Petroleum Refineries

* * * * *

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.
* * * * *
    43. Amend Method 10B of Appendix A-4 to Part 60 by revising 
Sections 2.1 and 6.2.3, and by revising the narrative in Section 12.2 
to read as follows:

Method 10B--Determination of Carbon Monoxide Emissions From Stationary 
Sources

* * * * *
    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.

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. * * *

    8.5 Sample for at least 10 minutes. At the end of the sampling 
time, close the sampling valve, and record the final volume and 
temperature readings. Conduct a leak-check as described in Section 
8.2. A yellow color in the final cadmium sulfate impinger indicates 
depletion of the absorbing solution. An additional cadmium sulfate 
impinger should be added for subsequent samples and the sample with 
yellow color in the final impinger should be voided.

    10.1.2 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.

    45. Amend Method 12 of Appendix A-5 to Part 60 by revising Section 
16.1 and adding Sections 16.4, 16.4.1, and 16.4.2 to read as follows:

Sources

* * * * *
    16.1 Simultaneous Determination of Particulate Matter and Lead 
Emissions. Method 12 may be used to simultaneously determine Pb 
provided: (1) acetone is used to remove particulate from the probe 
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, 
including the impingers, are treated and analyzed for Pb as 
described in Sections 8.0 and 11.0 of this method.
* * * * *
    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.

compounds (H2S, carbonyl sulfide, and carbon disulfide) from sulfur 
recovery units at onshore natural gas processing facilities, and

* * * * *
    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.

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

* * * * *
    6.1.1 Probe. Borosilicate glass, approximately \3/8\-in. (9-mm) 
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.)

Method 30B--Determination of Total Vapor Phase Mercury Emissions From 
Coal-Fired Combustion Sources Using Carbon Sorbent Traps

* * * * *
    8.2.2.1 Determination of Minimum Calibration Concentration or 
Mass. Based on your instrument's sensitivity and linearity, 
determine the calibration concentrations or masses that make up a 
representative low level calibration range. Verify that you are able 
to meet the multipoint calibration performance criteria in section 
11.0 of this method. Select a calibration concentration or mass that 
is no less than 2 times the lowest concentration or mass in your 
calibration curve. The lowest point in your calibration curve must 
be at least 5, and preferably 10, times the Method Detection Limit 
(MDL), which is the minimum amount of the analyte that can be 
detected and reported. The MDL must be determined at least once for 
the analytical system using an MDL study such as that found in 
section 15.0 of the EPA Method 301 (76 FR 28673, 5/18/2011). * * *

    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. * * *

    11.1.1.4.2 RMs Using a Grab Sampling Technique. Synchronize the 
RM and FTIR CEM measurements as closely as possible. For a grab 
sampling RM, record the volume collected and the exact sampling 
period for each sample. Synchronize the FTIR CEM so that the FTIR 
measures a spectrum of a similar cell volume at the same time as the 
RM grab sample was collected. Measure at least five independent 
samples with both the FTIR CEM and the RM for each of the minimum 
nine runs. Compare the run concentration averages by using the

    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.

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.

    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.

to calculate the accuracy, in percent, for each of the three SVA 
tests or the daily sample volume check:
[GRAPHIC] [TIFF OMITTED] TP09JA12.045

[[Page 1165]]

Where:

VM = Sample gas volume determined/reported by your PM 
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:

    Authority:  42 U.S.C. 7401, et seq.

    69. Amend Sec.  61.13 by revising paragraph (e)(1)(i) to read as 
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.
* * * * *
    70. Amend Sec.  61.33 by revising paragraph (a) to read as follows:

Sec.  61.33  Stack sampling.

    (a) Unless a waiver of emission testing is obtained under Sec.  
61.13, each owner or operator required to comply with Sec.  61.32(a) 
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:

Sec.  61.42  Emission standard.

    (a) Emissions to the atmosphere from rocket-motor test sites shall 
not cause time-weighted atmospheric concentrations of beryllium to 
exceed 75 microgram minutes per cubic meter ([mu]g-min/m \3\) (4.68 x 
10-9 pound minutes per cubic foot (lb-min/ft \3\)) of air 
within the limits of 10 to 60 minutes, accumulated during any 2

    (i) Use Method 108 in Appendix B to this part or Method 29 in 
Appendix A to part 60 for determining the arsenic emission rate, g/hr 
(lb/hr). The emission rate shall equal the arithmetic mean of the 
results of three 60-minute test runs.
* * * * *
    (e) * * *
    (1) * * *
    (i) Use Method 108 in Appendix B to this part or Method 29 in 
Appendix A to part 60 to determine the concentration of arsenic in the 
gas streams entering and exiting the control device. Conduct three 60-
minute test runs, each consisting of simultaneous testing of the inlet 
and outlet gas streams. The gas streams shall contain all the gas 
exhausted from the glass melting furnace.
* * * * *
    (2) Calculate the percent emission reduction for each run as 
follows:

[[Page 1166]]

[GRAPHIC] [TIFF OMITTED] TP09JA12.046

Where:

D = the percent emission reduction.
Cb = the arsenic concentration of the stack gas entering

    16.1.1 Inductively coupled plasma-atomic emission spectrometry 
(ICP-AES) may be used as an alternative to atomic absorption 
analysis provided the following conditions are met:
    16.1.1.1 Sample collection, sample preparation, and analytical 
preparation procedures are as defined in the method except as 
necessary for the ICP-AES application.
    16.1.1.2 The quality control procedures are conducted as 
prescribed.
    16.1.1.3 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.
    6.1.2 Samples may also be analyzed by cold vapor atomic

    8.1.1.1 Calibrate the meter box orifice. Use the techniques 
described in APTD-0576 (see Reference 9 in Section 17.0 of Method 5 
of Appendix A to Part 60). Calibration of the orifice meter at flow 
conditions that simulate the conditions at the source is suggested. 
Calibration should either be done with hydrogen or with some other 
gas having a similar Reynolds Number so that there is similarity 
between the Reynolds Numbers during calibration and during sampling. 
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.

    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).

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 63--NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS 
FOR SOURCE CATEGORIES

    80. The authority citation for part 63 continues to read as 
follows:

    Authority: 42 U.S.C. 7401 et seq.

    81. Amend Sec.  63.7 by revising paragraph (c)(2)(iii)(A) to read 
as follows:

Sec.  63.7  Performance testing requirements.

* * * * *
    (c) * * *
    (2) * * *
    (iii) * * *
    (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, 
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.

    (5) Recovery devices. The average VOC concentration in the vent 
upstream and downstream of the control device shall be determined using 
Method 25A or 25B of Appendix A to part 60 of this chapter for recovery 
devices. The average VOC concentration shall correspond to the volume 
measurement by taking into account the sampling system response time.
* * * * *
    (8) Where Method 25, 25A, or 25B is used to measure the percent 
reduction in VOC, the percent reduction across the combustion or 
recovery device shall be calculated as follows:
[GRAPHIC] [TIFF OMITTED] TP09JA12.047

Where:

R = control efficiency of control device, percent.
Ei = mass flow rate of VOC at the inlet to the combustion 
or recovery device as calculated under paragraph (c)(7) of this 
section, kg/hr.
Eo = mass flow rate of VOC at the outlet of the 
combustion or recovery device, as calculated under paragraph (c)(7) 
of this section, kg/hr.

    (g) Baseline outlet VOC concentration. The procedures in this 
paragraph shall be used to determine the outlet VOC concentration 
required in Sec.  63.563(b)(4), (6), (7), and (8) for combustion 
devices except flare, carbon adsorbers, condenser/refrigeration units, 
and absorbers, respectively, and to monitor the VOC concentration as 
required in Sec.  63.564(e), (g), (h), and (i). The owner or operator 
shall use the procedures outlined in Method 25A or 25B. For the 
baseline VOC concentration, the arithmetic average of the outlet VOC 
concentration from three test runs from paragraph (d) of this section 
shall be calculated for the control device. The VOC concentration shall 
be measured at least every 15 minutes. Compliance testing of VOC CEMS 
shall be performed using PS 8.

63.745(g)(2) or Sec.  63.746(b)(4) must be certified by the filter 
manufacturer or distributor, paint/depainting booth supplier, and/or 
the facility owner or operator using method 319 in Appendix A of this 
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).

Stationary Sources

* * * * *
    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:

    10.5 Temperature sensors. Use the procedure in Section 10.3 of 
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.
