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
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.
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.
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.
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.
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.
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.''
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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 i, 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 degC 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 microg/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 microg/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
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
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
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).
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.
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.
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.
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.
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.
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.
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.
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
  
  * * * * *
3. * * *
  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, 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.
  * * * * *
4. Amend Method 201A of Appendix M as follows:
  1. By revising sections 8.3.4(b) and 8.3.4.1.
  2. By revising sections 8.7.2.2 and 8.7.5.5(a).
  3. By revising the introductory text of section 10.1.
  4. By revising section 11.2.1.
  5. By revising Equation 9 in section 12.5.
  6. By removing section 10.5.
  7. 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 degC ( 18; degF). (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.

  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.
8. Amend Sec. 60.13 by revising paragraph (d)(1) to read as follows:

  (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.

  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.

  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).

  6.1.1.9 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.

  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-

  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.

  6.1 What do I need for the measurement system? You may use any equipment and supplies meeting the following specifications:
  
  (1) Sampling system components that are not evaluated in the system bias or system calibration error test must be glass, Teflon, or stainless steel. Other materials are potentially acceptable, subject to approval by the Administrator.
  
  (2) The interference, calibration error, and system bias criteria must be met.
  
  Page 1156
  
  (3) Sample flow rate must be maintained within 10 percent of the flow rate at which the system response time was measured.
  
  (4) All system components (excluding sample conditioning components, if used) must maintain the sample temperature above the moisture dew point. Ensure minimal contact between any condensate and the sample gas. Section 6.2 provides example equipment specifications for a NOX measurement system. Figure 7E-1 is a diagram of an example dry-basis measurement system that is likely to meet the method requirements and is provided as guidance. For wet-basis systems, you may use alternative equipment and supplies as needed (some of which are described in Section 6.2), provided that the measurement system meets the applicable performance specifications of this method.

  7.1.1 High-Level Gas. This concentration is chosen to set the calibration span as defined in Section 3.4. Choose this high-level concentration so that emission measurements will be within 20 to 100 percent of this concentration.
  
  * * * * *
  
  8.1.2 Determination of Stratification. Perform a stratification test at each test site to determine the appropriate number of sample traverse points. If testing for multiple pollutants or diluents at the same site, a stratification test using only one pollutant or diluent satisfies this requirement. A stratification test is not required for small stacks that are less than 4 inches in diameter. To test for stratification, use a probe of appropriate length to measure the NOX (or pollutant of interest) concentration at 12 traverse points located according to Table 1-1 or Table 1-2 of Method 1. Alternatively, you may measure at three points on a line passing through the centroidal area. Space the three points at 16.7, 50.0, and 83.3 percent of the measurement line. Sample for a minimum of twice the system response time (see Section 8.2.6) at each traverse point. Calculate the individual point and mean NOX concentrations. If the concentration at each traverse point differs from the mean concentration for all traverse points by no more than: (a) 5.0 percent of the mean concentration; or (b) 0.5 ppm (whichever is less restrictive), the gas stream is considered unstratified and you may collect samples from a single point that most closely matches the mean. If the 5.0 percent or 0.5 ppm criterion is not met, but the concentration at each traverse point differs from the mean concentration for all traverse points by no more than: (a) 10.0 percent of the mean; or (b) 1.0 ppm (whichever is less restrictive), the gas stream is considered to be minimally stratified, and you may take samples from three points. Space the three points at 16.7, 50.0, and 83.3 percent of the measurement line. Alternatively, if a 12-point stratification test was performed and the emissions shown to be minimally stratified (all points within 10.0 percent of their mean or within 1.0 ppm), and if the stack diameter (or equivalent diameter for a rectangular stack or duct) is greater than 2.4 meters (7.8 ft), then you may use 3-point sampling and locate the three points along the measurement line exhibiting the highest average concentration during the stratification test at 0.4, 1.2, and 2.0 meters from the stack or duct wall. If the gas stream is found to be stratified because the 10.0 percent or 1.0 ppm criterion for a 3-
  
  point test is not met, locate 12 traverse points for the test in accordance with Table 1-1 or Table 1-2 of Method 1. This stratification test may not be meaningful at sources with temporally varying emissions or where emission concentrations are low. In these cases, the stratification test is not required.
  
  * * * * *
  
  8.2.5 Initial System Bias and System Calibration Error Checks. Before sampling begins, determine whether the high-level or mid-
  
  level calibration gas best approximates the emissions and use it as the upscale gas. Introduce the upscale gas at the probe upstream of all sample conditioning components in system calibration mode. Record the time it takes for the measured concentration to increase to a value that is within 95 percent or 0.5 ppm (whichever is less restrictive) of a stable response for both the low-level and upscale gases. Continue to observe the gas concentration reading until it has reached a final, stable value. Record this value on a form similar to Table 7E-2.
  
  * * * * *
  
  16.2.2 Bag Procedure. Perform the analyzer calibration error test to document the calibration (both NO and NOX modes, as applicable). Fill a Tedlar or equivalent bag approximately half full with either ambient air, pure oxygen, or an oxygen standard gas with at least 19.5 percent by volume oxygen content. Fill the remainder of the bag with mid- to high-level NO in N2 (or other appropriate concentration) calibration gas. (Note that the concentration of the NO standard should be sufficiently high enough for the diluted concentration to be easily and accurately measured on the scale used. The size of the bag should be large enough to accommodate the procedure and time required. Contact the bag manufacturer for guidance on the applicability of Tedlar equivalent materials for NO.)

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 appropriate to prepare the tank, conduct the sampling, and correct the measured sample concentration.

  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.

  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.)

  16.4.2 The limit of quantitation for the ICP-AES must be demonstrated, and the sample concentrations reported should be no less than two times the limit of quantitation. The limit of quantitation is defined as ten times the standard deviation of the blank value. The standard deviation of the blank value is determined from the analysis of seven blanks. It has been reported that for mercury and those elements that form hydrides, a continuous-flow generator coupled to an ICP-AES offers detection limits comparable to cold vapor atomic absorption.

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

  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 degC (248 25 degF) to prevent moisture condensation; or Teflon where stack probes are below 210 degC. 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 degC (248 degF). 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 degC (248 degF) since it is extremely difficult to purge acid gases off these components. (These components are not quantitatively recovered and, hence, any collection of acid gases on these components would result in potential underreporting of these emissions. The applicable subparts may specify alternative higher temperatures.)

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

  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.

  Authority: 42 U.S.C. 7401, et seq.
70. 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.

71. Amend Sec. 61.33 by revising paragraph (a) to read as follows:
  
  Sec. 61.33 Stack sampling.
  
  (
  1. 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.

  (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:

  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 fluorescence spectrometry.

  Method 102--Determination of Particulate and Gaseous Mercury Emissions From Chlor-Alkali Plants (Hydrogen Streams)
  
  * * * * *
  
  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.
  
  * * * * *
78. Amend Method 104 in Appendix B to Part 61 as follows:
  1. By revising Section 4.1.
  2. By revising Section 11.5.3.

  4. By adding a new Section 16.
  Method 104--Determination of Beryllium Emissions From Stationary Sources
  
  * * * * *
  
  4.1 Matrix Effects. Analysis for Be by flame atomic absorption spectrophotometry is sensitive to the chemical composition and to the physical properties (e.g., viscosity, pH) of the sample. Aluminum and silicon, in particular, are known to interfere when present in appreciable quantities. The analytical procedure includes (optionally) the use of the Method of Standard Additions to check for these matrix effects, and sample analysis using the Method of Standard Additions if significant matrix effects are found to be present (see Reference 2 in Section 17.0).
  
  * * * * *
  
  11.5.3 Check for Matrix Effects (optional). Use the Method of Standard Additions (see Reference 2 in Section 17.0) to check at least one sample from each source for matrix effects on the Be results. If the results of the Method of Standard Additions procedure used on the single source sample do not agree to within 5 percent of the value obtained by the routine atomic absorption analysis, then reanalyze all samples from the source using the Method of Standard Additions procedure.

  16.1.3 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.

  (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.

28. 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 microg/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 microg/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.
  
  * * * * *
29. 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).

31. 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:
  
  Method 315--Determination of Particulate and Methylene Chloride Extractable Matter (MCEM) From Selected Sources at Primary Aluminum Production Facilities
  
  * * * * *
  
  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:

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.
  
  * * * * *
32. Amend Method 316 of Appendix A to Part 63 by revising Section 10.5 to read as follows:
  
  Method 316--Sampling and Analysis for Formaldehyde Emissions From Stationary Sources in the Mineral Wool and Wool Fiberglass Industries
  
  * * * * *
  
  10.5 Temperature gauges: Use the procedure in Section 4.3 of EPA Method 2 to calibrate in-stack temperature gauges. Dial thermometers, such as are used for the dry gas meter 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.
  
  * * * * *
33. Amend Method 321 of Appendix A to Part 63 by revising the definition for the term ``Df'' after equation (2) in Section 9.3.1 to read as follows:
  
  Test Method 321--Measurement of Gaseous Hydrogen Chloride Emissions at Portland Cement Kilns by Fourier Transform Infrared (FTIR) Spectroscopy
