Sources

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: This action proposes corrections and updates to regulations 
for source testing of emissions under various rules. This proposed rule 
includes corrections to inaccurate testing provisions, updates to 
outdated procedures, and approved alternative procedures that provide 
testers enhanced flexibility. The revisions will improve the quality of 
data but will not impose new substantive requirements on source owners 
or operators.

DATES: Comments must be received on or before February 11, 2020.
    Public Hearing: If a public hearing is requested by December 18, 
2019, then we will hold a public hearing. If a public hearing is

inquire if a hearing will be held, please contact Mrs. Lula Melton by 
email at melton.lula@epa.gov or phone at (919) 541-2910. The last day 
to pre-register in advance to speak at the public hearing will be 
December 26, 2019. If held, the public hearing will convene at 9:00 
a.m. (local time) and will conclude at 4:00 p.m. (local time).
    Because this hearing is being held at a U.S. government facility, 
individuals planning to attend the hearing should be prepared to show 
valid picture identification to the security staff in order to gain 
access to the meeting room. Please note that the REAL ID Act, passed by 
Congress in 2005, established new requirements for entering federal 
facilities. For purposes of the REAL ID Act, EPA will accept 
government-issued IDs, including drivers' licenses, from the District 
of Columbia and all states and territories except from American Samoa. 
If your identification is issued by American Samoa, you must present an 
additional form of identification to enter the federal building where 
the public hearing will be held. Acceptable alternative forms of 
identification include: Federal employee badges, passports, enhanced 
driver's licenses, and military identification cards. For additional 
information for the status of your state regarding REAL ID, go to: 
https://www.dhs.gov/real-id-enforcement-brieffrequently-asked-questions. Any objects brought into the building need to fit through 
the security screening system, such as a purse, laptop bag, or small 
backpack. Demonstrations will not be allowed on federal property for 
security reasons.
    Submit your comments identified by Docket ID No. EPA-HQ-OAR-2018-
0815 at https://www.regulations.gov (our preferred method) or the other 
methods identified in the ADDRESSES section. Once submitted, comments 
cannot be edited or removed from the docket. Do not submit 
electronically any information you consider to be Confidential Business 
Information (CBI) or other information whose disclosure is restricted 
by statute. Multimedia submissions (audio, video, etc.) must be 
accompanied by a written comment. The written comment is considered the 
official comment and should include discussion of all points you wish 
to make. The EPA will generally not consider comments or comment 
contents located outside of the primary submission (i.e., on the Web, 
Cloud, or other file sharing system). For additional submission 
methods, the full EPA public comment policy, information about CBI or 
multimedia submissions, and general guidance on making effective 
comments, please visit https://www.epa.gov/dockets/commenting-epa-dockets.

II. General Information

A. Does this action apply to me?

    The proposed amendments apply to industries that are subject to the 
current provisions of 40 CFR parts 51, 60, 61, and 63. We did not list 
all of the specific affected industries or their North American 
Industry Classification System (NAICS) codes herein since there are 
many affected sources in numerous NAICS categories. If you have any 
questions regarding the applicability of this action to a particular 
entity, consult either the air permitting authority for the entity or 
your EPA Regional representative as listed in 40 CFR 63.13.

B. What action is the Agency taking?

    This action proposes corrections and revisions to source test 
methods, performance specifications (PS), and associated regulations. 
The corrections and revisions consist primarily of typographical 
errors, updates to testing procedures, and the addition of alternative 
equipment and methods the Agency has deemed acceptable to use.

III. Background

    The EPA catalogs errors and corrections, as well as necessary 
revisions to test methods, performance specifications, and associated 
regulations in 40 CFR parts 51, 60, 61, and 63 and periodically updates 
and revises these provisions. The most recent updates and revisions 
were promulgated on November 14, 2018 (83 FR 56713). This proposed rule 
addresses necessary corrections and revisions identified subsequent to 
that final action, many of which were brought to our attention by 
regulated sources and end-users, such as environmental consultants and 
compliance professionals. These revisions will improve the quality of 
data obtained and give source testers the flexibility to use newly-
approved alternative procedures.

IV. Incorporation by Reference

    The EPA proposes to incorporate by reference one ASTM International 
standard. Specifically, the EPA proposes to incorporate ASTM D 2369-10, 
which covers volatile organic content of coatings, in Method 24. This 
standard was developed and adopted by ASTM International and may be 
obtained from http://www.astm.org or from the ASTM at 100 Barr Harbor 
Drive, P.O. Box C700, West Conshohocken, PA 19428-2959.
    The EPA proposes to incorporate by reference SW-846 Method 6010D 
and SW-846 Method 6020B in Method 12. Method 6010D covers inductively

[[Page 68071]]

coupled plasma-atomic emission spectrometry (ICP-AES) analysis, and 
Method 6020B covers inductively coupled plasma-mass spectrometry (ICP-
MS) analysis. These methods may be obtained from https://www.epa.gov or 
from the U.S. Environmental Protection Agency, 1200 Pennsylvania Avenue 
NW, Washington, DC 20460.
    The EPA proposes to incorporate by reference Gas Processors 
Association (GPA) 2166 and GPA 2174 in subpart KKKK of part 60, which 
involve procedures for obtaining samples from gaseous and liquid fuels, 
respectively. These GPA standards were developed and adopted by the Gas 
Processors Association and may be obtained from https://gpamidstream.org/ or from the Gas Processors Association, 6526 East 
60th Street, Tulsa, OK 74145.
    The EPA proposes to incorporate by reference International 
Organization for Standardization (ISO) 10715 in subpart KKKK of part 
60. This standard involves procedures for obtaining samples from 
gaseous fuels. This standard was developed by the International 
Organization for Standardization and may be obtained from https://www.iso.org/home.html or from the IHS Inc., 15 Inverness Way East, 
Englewood, CO 80112.
    ASTM D4057-5 (Reapproved 2000), ASTM D4177-95 (Reapproved 2000), 
ASTM D5287-97 (Reapproved 2002), ASTM D6348-03, ASTM D6784-02 
(Reapproved 2008), and ASME PTC 19.10-1981 were previously approved for 
incorporation by reference, and no changes are proposed.
    The EPA proposes to update the ASTM standards referenced in Method 
311, but these standards are not incorporated by reference. The EPA is 
not proposing to update the ASTM standards referenced in Performance 
Standard 18, which are not incorporated by reference.

V. Summary of Proposed Amendments

    The following amendments are being proposed.

A. Method 201A of Appendix M of Part 51

    In Method 201A, section 1.2, the erroneous gas filtration 
temperature limit of 30 [deg]C would be revised to 29.4 [deg]C. In 
section 1.6, the erroneous word ``recommended'' would be corrected to 
``required.'' Section 6.2.1(d) would be revised to allow polystyrene 
petri dishes as an alternative to polyethylene due to the lack of 
commercially available polyethylene petri dishes. The polystyrene petri 
dishes offer similar chemical resistivity to acids and inorganics as 
polyethene and have been shown to transfer extreme low residual 
gravimetric mass to filters when used in ambient air applications. In 
section 8.6.6, the erroneous stack temperature of 10 [deg]C 
would be revised to 28 [deg]C. In section 17.0, the 
erroneous caption for Figure 7 would be corrected from ``Minimum Number 
of Traverse Points for Preliminary Method 4 Traverse'' to ``Maximum 
Number of Required Traverse Points,'' and the erroneous y-axis label 
would be corrected from ``Minimum Number of Traverse Points'' to 
``Maximum Number of Traverse Points.''

B. General Provisions (Subpart A) of Part 60

    In the General Provisions of part 60, Sec.  60.17(h) would be 
revised to add ASTM D2369-10 to the list of incorporations by reference 
and to re-number the remaining consensus standards that are 
incorporated by reference in alpha-numeric order.
    In part 60, Sec.  60.17(j) would be revised to add SW-846-6010D and 
SW-846-6020B to the list of incorporations by reference and to re-
number the remaining standards that are incorporated by reference in 
alpha-numeric order.
    In part 60, Sec.  60.17(k) would be revised to add GPA Standards 
2166-17 and 2174-14 to the list of incorporations by reference and to 
re-number the remaining GPA standards that are incorporated by 
reference in alpha-numeric order.
    In part 60, Sec.  60.17(l) would be revised to add ISO 10715:1997 
to the list of incorporations by reference.

C. Standards of Performance for New Residential Wood Heaters (Subpart 
AAA) of Part 60

    In Sec.  60.534(h), the language would be amended based on comments 
received in response to an Advance Notice of Proposed Rulemaking 
(ANPRM), for Standards of Performance for New Residential Wood Heaters, 
New Residential Hydronic Heaters and Forced-Air Furnaces (83 FR 61585, 
November 30, 2018). Several commenters stated that the final clause of 
these existing paragraphs would create loopholes that allow 
manufacturers and test labs to withhold critical testing data. The EPA 
recognizes that this provision was not intended to create an avenue for 
omissions, so we are proposing language to clarify these communications 
and their reporting.

D. Standards of Performance for Municipal Solid Waste Landfills That 
Commenced Construction, Reconstruction, or Modification After July 17, 
2014 (Subpart XXX) of Part 60

    In Sec.  60.766(a)(3), the text for calibration of temperature 
measurement would be revised to provide clarity and improve the 
consistency of implementation.

E. Standards of Performance for Commercial and Industrial Solid Waste 
Incineration Units (Subpart CCCC) of Part 60

    Subpart CCCC of part 60 would be revised to clarify that (1) 
initial and annual performance testing for particulate matter (PM) for 
waste-burning kilns and energy recovery units (ERU) is to be conducted 
using Method 5 or Method 29 of Appendix A of part 60; (2) the required 
particulate matter continuous parameter monitoring system (PM CPMS) is 
used to demonstrate continuing compliance with the PM emission limit; 
and (3) heat input information must be reported for each ERU. The 
current language in Sec. Sec.  60.2110(i), (i)(1)(iii) and 60.2145(b), 
when read together, make it clear that for purposes of demonstrating 
compliance with the PM emission limit, there must be initial testing 
and subsequently, annually and for ongoing continuous demonstration of 
compliance, that data from the compliant performance test in turn must 
be used to set an operating limit for the PM CPMS. Tables 6 and 7, 
however, presently specify PM CPMS as the performance test method for 
determining compliance.
    Paragraphs 60.2110(i)(1) and 60.2145(j) would be revised to clarify 
that the PM CPMS coupled with an operating limit is used for continuing 
compliance demonstration with the PM emission limit. Paragraphs 
60.2110(i)(1)(iii) and (i)(2) would be revised to include Method 29 as 
an alternative to Method 5 to measure PM in determining compliance with 
the PM emission limit. Paragraph 60.2145(j) would also be revised to 
add PM to the list of pollutants for which performance tests are 
conducted annually. Paragraph (p) would be added to Sec.  60.2210 to 
require that annual reports include the annual heat input and average 
annual heat input rate of all fuels being burned in ERUs in order to 
verify which subcategory of ERU applies.
    The required annual performance test timeframe would be changed 
from ``between 11 and 13 calendar months following the previous 
performance test'' to ``no later than 13 calendar

[[Page 68072]]

months following the previous performance test'' in paragraphs 
60.2145(y)(3) and 60.2150. The current two-month testing range can 
present operational and testing challenges for facilities that have 
multiple commercial and industrial solid waste incineration (CISWI) 
units, and this revision would be consistent with other rules, such as 
the National Emission Standards for Hazardous Air Pollutants from 
Hazardous Waste Combustors, to which CISWI units may be subject.
    Table 6 (Emission Limitations for Energy Recovery Units) and Table 
7 (Emission Limitations for Waste-Burning Kilns) would be revised to 
clarify the performance test method for PM. The fourth column of the 
``Particulate matter (filterable)'' row of Table 6 would be revised to 
remove the requirement to use a PM CPMS as the performance test method 
for large ERU. The fourth column of the ``Particulate matter 
(filterable)'' row of Table 7 would be revised to remove the 
requirement to use a PM CPMS and to instead specify Methods 5 and 29 as 
alternatives for measuring PM to determine compliance with the PM 
limit. The third column of the ``Particulate matter (filterable)'' row 
of Table 7 would be changed from a 30-day rolling average to specify a 
3-run average with a minimum sample volume of 2 dry standard cubic 
meter (dscm) per run.

F. Emission Guidelines and Compliance Times for Commercial and 
Industrial Solid Waste Incineration Units (Subpart DDDD) of Part 60

    Subpart DDDD of part 60 would be revised to clarify that (1) 
initial and annual performance testing for PM for waste-burning kilns 
and ERU is to be conducted using Method 5 or Method 29 of Appendix A of 
part 60; (2) the required PM CPMS is used to demonstrate continuing 
compliance with the PM emission limit; and (3) heat input information 
must be reported for ERU. The current language in Sec. Sec.  60.2675(i) 
and (i)(1)(iii) and 60.2710(b), when read together, makes it clear that 
for purposes of demonstrating compliance for PM, performance testing 
must be used initially and then annually and for purposes of ongoing 
continuous demonstration of compliance, data from the compliant 
performance test is in turn used to set an operating limit for the PM 
CPMS. Tables 7 and 8, however, presently specify PM CPMS as the 
performance test method for determining compliance.
    Paragraphs 60.2675(i)(1) and 60.2710(j) would be revised to clarify 
that the PM CPMS is used for continuing compliance demonstration with 
the PM emission limit. Paragraph 60.2710(j) would be also revised to 
clarify that PM performance tests are conducted annually and Sec. Sec.  
60.2675(i)(1)(iii) and (i)(2) would be revised to include Method 29 as 
an alternative to Method 5 to measure PM in determining compliance with 
the PM emission limit.
    Also, the required annual performance test timeframe would be 
changed from ``between 11 and 13 calendar months following the previous 
performance test'' to ``no later than 13 calendar months following the 
previous performance test'' in Sec. Sec.  60.2710(y)(3) and 60.2715. 
The current two-month testing range can present operational and testing 
challenges for facilities that have multiple CISWI units, and this 
revision would be consistent with other rules, such as the National 
Emission Standards for Hazardous Air Pollutants from Hazardous Waste 
Combustors, to which CISWI units may be subject.
    Table 7 (Emission Limitations for Energy Recovery Units) and Table 
8 (Emission Limitations That Apply to Waste-Burning Kilns) would be 
revised to clarify the performance test method for PM. The fourth 
column of the ``Particulate matter filterable'' row of Table 7 would be 
revised to remove the requirement to use a PM CPMS as the performance 
test method for large ERU. The fourth column of the ``Particulate 
matter filterable'' row of Table 8 would be revised to specify Methods 
5 and 29 as alternatives for measuring PM to determine compliance with 
the PM emission limit. The third column of the ``Particulate matter 
filterable'' row of Table 8 would be changed from a 30-day rolling 
average to specify a 3-run average with a minimum sample volume of 1 
dscm per run.

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

    In Table 2 of subpart JJJJ, text would be added to clarify that 
when stack gas flowrate measurements are necessary, they must be made 
at the same time as pollutant concentration measurements unless the 
option in Method 1A is applicable and is being used.

H. Standards of Performance for Stationary Combustion Turbines (Subpart 
KKKK) of Part 60

    In 2006, EPA promulgated the combustion turbine criteria pollutant 
NSPS, Subpart KKKK of 40 CFR part 60 (71 FR 38482, July 6, 2006). This 
rule, which includes a sulfur dioxide (SO2) emissions 
standard for all fuels, including natural gas, also made provisions to 
minimize the compliance burden for owners/operators of combustion 
turbines burning natural gas and/or low sulfur distillate oil. At the 
time, the Agency recognized that any SO2 testing 
requirements for owners/operators of combustion turbines burning 
natural gas would result in compliance costs without any associated 
environmental benefit.
    As currently written, the initial and subsequent performance tests 
required in Sec.  60.4415 may be satisfied by fuel analyses performed 
by the facility, a contractor, the fuel vendor, or any other qualified 
agency as described in Sec.  60.4415(a)(1). However, the fuel sample 
must be collected using ASTM D5287 (Standard Practice for Automatic 
Sampling of Gaseous Fuels). This method is not typically used by owner/
operators of natural gas pipelines and, as a result, tariff sheets 
cannot be used without approval of the alternate method. This is 
creating a situation where the owner/operators of the combustion 
turbines must do their own sampling and testing, a burden that was not 
intended in the original rulemaking.
    To align the rule requirements with the original intent of subpart 
KKKK, the EPA is proposing to include additional sampling methods in 
order for tariff sheets to be used to satisfy the SO2 
performance testing requirements. Specifically, Sec.  60.4415(a)(1) 
would be amended to include GPA 2166 and ISO 10715 for manual sampling 
of gaseous fuels. In addition, manual sampling method GPA 2174 would be 
added for liquid fuels. The EPA is soliciting comment regarding whether 
additional sampling methods should also be included and whether 
additional test methods should be included in Sec. Sec.  60.4360 and 
60.4415. Specifically, for sampling, EPA is soliciting comment on 
including American Petroleum Institute (API) Manual of Petroleum 
Measurement Standards, Chapter 14--Natural Gas Fluids Measurement, 
Section 1--Collecting and Handling of Natural Gas Samples for Custody 
Transfer, 7th Edition, August 2017. For determining the sulfur content 
of liquid fuels, EPA is soliciting comment on adding ASTM D5623-94 
(2014) (Standard Test Method for Sulfur Compounds in Light Petroleum 
Liquids by Gas Chromatography and Sulfur Selective Detection) and ASTM 
D7039-15a (Standard Test Method for Sulfur in Gasoline and Diesel Fuel 
by Monochromatic Wavelength Dispersive X-ray Fluorescence 
Spectrometry). For determining the sulfur content of gaseous fuels, EPA 
is soliciting comment on adding GPA D2140-17 (Liquefied Petroleum Gas 
Specifications

[[Page 68073]]

and Test Methods) and GPA 2261-19 (Analysis for Natural Gas and Similar 
Gaseous Mixtures by Gas Chromatography).
    These amendments would also be consistent with the burden reduction 
proposed by the EPA in 2012 (77 FR 52554, August 29, 2012). In that 
proposal, the EPA proposed amendments to subpart KKKK that would 
eliminate the SO2 emissions limit for owner/operators of 
combustion turbines burning natural gas and/or low sulfur distillate 
and add additional sampling and test methods for owners/operators of 
combustion turbines burning other fuels. (The EPA has not taken final 
action on that proposal.)

I. Standard of Performance for New Residential Wood Heaters, New 
Residential Hydronic Heaters and Forced-Air Furnaces (Subpart QQQQ) of 
Part 60

    In subpart QQQQ, in Sec.  60.5476(i), the language would be amended 
based on comments received in response to an ANPRM for Standards of 
Performance for New Residential Wood Heaters, New Residential Hydronic 
Heaters and Forced-Air Furnaces (83 FR 61585, November 30, 2018). 
Several commenters stated that the final clause of these existing 
paragraphs would create loopholes that allow manufacturers and test 
labs to withhold critical testing data. The EPA recognizes that this 
provision was not intended to create an avenue for omissions, so we are 
proposing language to clarify these communications and their reporting.

J. Method 4 of Appendix A-3 of Part 60

    In Method 4, the erroneous leak check procedures in section 8.1.3 
would be corrected; the erroneous section 8.1.4.2 would be corrected; 
and in the table in section 9.1, the erroneous reference to section 
8.1.1.4 would be replaced with section 8.1.3.2.2.
    Method 4 would be revised to standardize the constants between 
Methods 4 and 5, and more significant digits would be added to 
constants to remove rounding and truncation errors. Also, the option 
for volumetric determination of the liquid content would be deleted to 
remove the unnecessary density conversion. We believe most method users 
have moved to gravimetric measurement of the liquid contents to lower 
the cost and increase the accuracy of the liquid measurement. Revisions 
would occur in various sections (2.1, 6.1.5, 11.1, 11.2, 12.1.1, 
12.1.2, 12.1.3, 12.2.1, and 12.2.2) and Figures 4-4 and 4-5.

K. Method 5 of Appendix A-3 of Part 60

    In Method 5, sections 6.2.4 and 8.1.2 would be revised to allow 
polystyrene petri dishes as an alternative to polyethylene due to the 
lack of commercially available polyethylene petri dishes. The 
polystyrene petri dishes offer similar chemical resistivity to acids 
and inorganics as polyethene and have been shown to transfer extreme 
low residual gravimetric mass to the filters when used in ambient air 
applications.
    Method 5 would also be revised to standardize the constants between 
Methods 4 and 5, and more significant digits would be added to 
constants to remove rounding and truncation errors. Also, the option 
for volumetric determination of the liquid content would be deleted to 
remove the unnecessary density conversion. We believe most method users 
have moved to gravimetric measurement of the liquid contents to lower 
the cost and increase the accuracy of the liquid measurement. Revisions 
would occur in various sections (6.1.1.8, 6.2.5, 8.7.6.4, 12.1, 12.3, 
12.4, 12.11.1, 12.11.2, 16.1.1.4, and 16.2.3.3) and in Figure 5-6.

L. Method 7C of Appendix A-4 of Part 60

    In Method 7C, in section 7.2.11, the erroneous chemical compound, 
sodium sulfite would be corrected to sodium nitrite.

M. Method 7E of Appendix A-4 of Part 60

    In Method 7E, section 8.5 would be revised to ensure that the 
specified bias and calibration error checks are performed consistently. 
The results of the post-run system bias and calibration error checks 
are used to validate the run, as well as to correct the results of each 
individual test run for bias found in the sampling system. The more 
frequently these checks are performed, the more accurate the bias 
adjusted data will be.

N. Method 12 of Appendix A-5 of Part 60

    In Method 12, sections 7.1.2, 8.7.1.6, 8.7.3.1, and 8.7.3.6 would 
be revised to remove references regarding the use of silicone grease, 
which is no longer allowed when conducting Method 5, and section 12.3 
would be revised to correctly refer to the title of section 12.4 of 
Method 5.
    Section 16.1 allows measurements of PM emissions in conjunction 
with the lead measurement but does not currently provide enough detail 
to ensure proper PM measurement; the proposed revisions to section 16.1 
would provide testers with the necessary procedures to execute the PM 
and lead emissions measurements using one sampling train.
    Sections 16.3, 16.4.1, 16.4.2, 16.5, 16.5.1, and 16.5.2 would be 
revised to specify appropriate EPA analytical methods, as well as 
supporting quality assurance procedures, as part of the allowed 
alternatives to use inductively coupled plasma-atomic emission 
spectrometry (ICP-AES) and inductively coupled plasma-mass spectrometry 
(ICP-MS) for sample analysis. Section 16.0 currently allows three 
alternatives to the atomic absorption analysis otherwise required in 
Method 12, specifically ICP-AES in section 16.4, ICP-MS in section 
16.5, and cold vapor atomic fluorescence spectrometry (CVAFS) in 
section 16.6. In regard to the options to use ICP-AES and ICP-MS for 
analysis of lead, sections 16.4 and 16.5 currently do not include any 
specifics for applying these candidate analytical techniques, nor any 
procedures for assessing data quality. The proposed revisions would 
provide the needed specificity by referencing existing EPA methods for 
ICP-AES and ICP-MS along with supporting quality assurance 
requirements. The option to use CVAFS to measure lead (section 16.6) 
would be removed since CVAFS for lead is not generally available, and 
there is no existing EPA method for conducting it.

O. Method 16B of Appendix A-6 of Part 60

    In Method 16B, in section 2.1, the erroneous phrase ``an integrated 
gas sample'' would be corrected to ``a gas sample.'' In sections 6.1 
and 8.2, the reference to section 8.4.1 would be changed to 8.3.1 since 
section 8.4.1 would be renumbered to 8.3.1. The text in section 8.3, 
``Analysis. Inject aliquots of the sample into the GC/FPD analyzer for 
analysis. Determine the concentration of SO2 directly from 
the calibration curves or from the equation for the least-squares 
line.'' would be moved to section 11.1 to be consistent with EPA test 
method formatting. Sections 8.4, 8.4.1, and 8.4.2 would be renumbered 
to 8.3, 8.3.1, and 8.3.2, respectively since the text in section 8.3 
would be moved to section 11.1. In section 11.1, the sentence ``Sample 
collection and analysis are concurrent for this method (see section 
8.3).'' would be deleted. Section 11.2 would be added so that a uniform 
set of analysis results would be obtained over the test period.

[[Page 68074]]

P. Method 16C of Appendix A-6 of Part 60

    In Method 16C, in section 13.1, ``gas concentration'' would be 
replaced with ``span'' for clarity.

Q. Method 24 of Appendix A-7 of Part 60

    In Method 24, section 6.2, the most recent version of ASTM D 2369 
(ASTM D 2369-10) would be added.

R. Method 25C of Appendix A-7 of Part 60

    We are proposing to change the correction of non-methane organic 
compounds (NMOC) within the method. Currently, we require the NMOC to 
be corrected by nitrogen or oxygen content. The correction is done by 
nitrogen unless the nitrogen content exceeds a threshold of 20 percent. 
When the nitrogen threshold is above 20 percent, the correction is done 
by oxygen. We are considering multiple options for revisions, which are 
outlined in greater detail in docket ID EPA-HQ-OAR-2018-0815, based on 
data provided by industry also provided in docket ID EPA-HQ-OAR-2018-
0815. The revisions to the correction that we are considering are for 
when only oxygen is used as a NMOC correction, setting a rainfall 
threshold in lieu of a nitrogen percent threshold, and requiring a 
methane measurement and using methane only as the correction. We have 
provided amendatory text for each option in docket ID EPA-HQ-OAR-2018-
0815.

S. Method 26 of Appendix A-8 of Part 60

    In Method 26, in section 8.1.2, the misspelled word 
``undereporting'' in the next to the last sentence would be corrected 
to ``under reporting.''

T. Method 26A of Appendix A-8 of Part 60

    In Method 26A, section 6.1.3, a reference to section 6.1.1.7 of 
Method 5 would be added to make the filter temperature sensor placement 
consistent with the requirements in Method 5. Also, in section 6.1.3, 
the requirement that the filter temperature sensor must be encased in 
glass or Teflon would be added because of the reactive nature of the 
halogen acids. In section 8.1.5, the misspelled word ``undereporting'' 
would be corrected to ``under reporting.''

U. Performance Specification 4B of Appendix B of Part 60

    In Performance Specification 4B, the response time in section 4.5 
would be changed from ``must not exceed 2 minutes'' to ``must not 
exceed 240 seconds'' to be consistent with the response time in 
Performance Specification 4A.

V. Performance Specification 5 of Appendix B of Part 60

    In Performance Specification 5, section 5.0, the erroneous term 
``users manual'' would be replaced with ``user's manual,'' and in the 
note in section 8.1, the sentence ``For Method 16B, you must analyze a 
minimum of three aliquots spaced evenly over the test period.'' would 
be added to provide consistency with the number of aliquots analyzed in 
Method 16B, which may be used as the reference method.

W. Performance Specification 6 of Appendix B of Part 60

    In Performance Specification 6, section 13.1 would be revised to 
clarify that the calibration drift test period for the analyzers 
associated with the measurement of flow rate should be the same as that 
for the pollutant analyzer that is part of the continuous emission rate 
monitoring system (CERMS). Section 13.2 would be revised for clarity 
and to be consistent with the requirements in Performance Specification 
2.

X. Performance Specification 8 of Appendix B of Part 60

    In Performance Specification 8, a new section 8.3 would be added to 
require that an instrument drift check be performed as described in 
Performance Specification 2, and the existing sections 8.3, 8.4, and 
8.5 would be re-numbered as 8.4, 8.5, and 8.6, respectively.

Y. Performance Specification 9 of Appendix B of Part 60

    In Performance Specification 9, the quality control and performance 
audit sections would be clarified. In section 7.2, a requirement that 
performance audit gas must be an independent certified gas cylinder or 
cylinder mixture certified by the supplier to be accurate to two 
percent of the tagged value supplied with the cylinder would be added.
    In section 8.3, an incorrect reference concerning quality control 
requirements that pertain to the 7-day drift test would be clarified 
and corrected, and an incorrect reference to the error calculation 
equation would be corrected. In section 8.4, a requirement to ensure 
that performance audit samples challenge the entire sampling system 
including the sample transport lines would be added, and quality 
control requirements that must be met for performance audit tests would 
be specified by adding references to sections 13.3 and 13.4.
    In section 10.1, the erroneous word ``initial'' would be deleted 
from the title, ``Initial Multi-Point Calibration,'' and the quality 
control requirements that must be met for multi-point calibrations 
would be specified by referencing sections 13.1 and 13.2 in addition to 
13.3. Sections 10.1 and 10.2 would be clarified such that calibrations 
may be performed at the instrument rather than through the entire 
sampling system.
    In section 13.1, language would be clarified to ensure that every 
time a triplicate injection is performed, the calibration error must be 
less than or equal to 10 percent of the calibration gas value. In 
section 13.2, language would be clarified to specify that the linear 
regression correlation coefficient must be determined to evaluate the 
calibration curve for instrument response every time the continuous 
emission monitoring system (CEMS) response is evaluated over multiple 
concentration levels. Section 13.4 would be added to describe the 
quality control requirements for the initial and periodic performance 
audit test sample.

Z. Performance Specification 18 of Appendix B of Part 60

    In Performance Specification 18, section 2.3 would be revised to 
clarify that Method 321 is only applicable to Portland cement plants. 
Also, in section 11.9.1, the reference to Method 321 would be deleted 
because Method 321 is specific to Portland cement plants, and it is 
already specified in the applicable regulations.

AA. Procedure 1 of Appendix F of Part 60

    In Procedure 1, section 5.2.3(2), the criteria for cylinder gas 
audits (CGAs) as applicable to diluent monitors would be specified for 
clarity.

BB. Method 107 of Appendix B of Part 61

    In Method 107, the erroneous equation 107-3 would be corrected by 
adding the omitted plus (+) sign.

CC. General Provisions (Subpart A) of Part 63

    In the General Provisions of part 63, in Sec.  63.2, the definition 
of alternative test method would be revised to exclude ``that is not a 
test method in this chapter and'' because doing so clarifies that to 
use methods other than those required by a specific subpart requires 
the alternative test method review and approval process.

[[Page 68075]]

    Section 63.14(h) would be revised to add ASTM D 4457, ASTM D 4747, 
ASTM D 4827, and ASTM D 5910 to the list of incorporations by reference 
and to re-number the remaining consensus standards that are 
incorporated by reference in alpha-numeric order.

DD. Portland Cement Manufacturing (Subpart LLL) of Part 63

    In subpart LLL, the units of measure in Equations 12, 13, 17, 18, 
and 19 would be revised to add clarity and consistency. Equations 12 
and 13 need to be corrected so that the operating limit units of 
measure is calculated correctly. The calculation of the operating limit 
is established by a relationship of the total hydrocarbons (THC) CEMS 
signal to the organic HAPs compliance concentration. As illustrated in 
Table 1 in Part 63, Subpart LLL, the THC and organic HAP emissions 
limits units are in ppmvd corrected to 7 percent oxygen. Therefore, the 
average organic HAP values in equation 12 need to be in ppmvd, 
corrected to 7 percent oxygen, instead of ppmvw. The THC CEMS monitor 
units of measure are ppmvw, as propane and the variables would be 
updated to reflect this. The variables in equations 13 and 19 reference 
variables in equations 12 and 18, respectively. Those variables would 
be updated for consistency between the equations.
    The units of measure in equation 17 should be the monitoring 
system's units of measure. It is possible for those systems to be on 
either a wet or a dry basis. Currently, the equation is only on a wet 
basis, even though it should be on the basis of the monitor (wet or 
dry). The changes to the units of measure from ppmvw to ppmv takes 
either possibility into account. For Equations 17 and 18, the operating 
limit units of measure would be changed to the units of the CEMS 
monitor, ppmv.

EE. Method 301 of Appendix A of Part 63

    In Method 301, section 11.1.3, the erroneous SD in equation 301-13 
would be replaced with SDd.

FF. Method 308 of Appendix A of Part 63

    In Method 308, section 12.4, erroneous equation 308-3 would be 
corrected, and in section 12.5, erroneous equation 308-5 would be 
corrected.

GG. Method 311 of Appendix A of Part 63

    In Method 311, in sections 1.1 and 17, the ASTM would be updated. 
Specifically, in section 1.1, ASTM D4747-87 would be updated to D4747-
02, and ASTM D4827-93 would be updated to D4827-03. Also, in section 
1.1, Provisional Standard Test Method, PS 9-94 would be replaced with 
D5910-05. In section 17, ASTM D4457-85 would be updated to ASTM D4457-
02, and ASTM D4827-93 would be updated to ASTM D4827-03.

HH. Method 315 of Appendix A of Part 63

    In Method 315, in Figure 315-1, an omission would be corrected by 
adding a ``not to exceed'' blank criteria for filters used in this test 
procedure. The blank criteria was derived from evaluation of blank and 
spiked filters used to prepare Method 315 audit samples. We would set 
the allowable blank correction for filters based on the greater of two 
criteria. The first criterion requires the blank to be at least 10 
times the measured filter blanks from the audit study. The second 
criterion requires the blank to be at least 5 times the resolution of 
the analytical balance required in Method 315. The ``not to exceed'' 
value would, therefore, be based on the second criterion (balance 
resolution) because it is the higher of the two criteria.

II. Method 316 of Appendix A of Part 63

    In Method 316, section 1.0, the erroneous positive exponents would 
be corrected to negative exponents. Also, the title of section 1.0, 
``Introduction,'' would be changed to ``Scope and Application'' to be 
consistent with the Environmental Monitoring Management Council (EMMC) 
format for test methods.

JJ. Method 323 of Appendix A of Part 63

    In the title of Method 323, the misspelled word ``Derivitization'' 
would be corrected to ``Derivatization,'' and in section 2.0, the 
misspelled word ``colorietrically'' would be corrected to 
``colorimetrically.''

VI. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at http://www2.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    This action is not a significant regulatory action and was 
therefore not submitted to the Office of Management and Budget (OMB) 
for review.

B. Executive Order 13771: Reducing Regulations and Controlling 
Regulatory Costs

    This action is expected to be an Executive Order 13771 deregulatory 
action. This proposed rule is expected to provide meaningful burden 
reduction by updating and clarifying methods and performance 
specifications, thereby improving data quality, and also by providing 
source testers flexibility by incorporating approved alternative 
procedures.

C. Paperwork Reduction Act (PRA)

    This action does not impose an information collection burden under 
the PRA. The amendments being proposed in this action to the test 
methods, performance specifications, and testing regulations only make 
corrections and minor updates to existing testing methodology. In 
addition, the proposed amendments clarify performance testing 
requirements.

D. Regulatory Flexibility Act (RFA)

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

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandate as described in 
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect 
small governments. The action imposes no enforceable duty on any state, 
local or tribal governments or the private sector.

F. 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.

[[Page 68076]]

G. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action does not have tribal implications, as specified in 
Executive Order 13175. This action would correct and update existing 
testing regulations. Thus, Executive Order 13175 does not apply to this 
action.

H. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that concern environmental health or safety risks 
that the EPA has reason to believe may disproportionately affect 
children, per the definition of ``covered regulatory action'' in 
section 2-202 of the Executive Order. This action is not subject to 
Executive Order 13045 because it does not concern an environmental 
health risk or safety risk.

I. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution or Use

    This action is not subject to Executive Order 13211 because it is 
not a significant regulatory action under Executive Order 12866.

J. National Technology Transfer and Advancement Act and 1 CFR Part 51

    This action involves technical standards. The EPA proposes to use 
ASTM D 2369 in Method 24. The ASTM D 2369 standard covers volatile 
content of coatings. The EPA proposes to use ASTM D 4457, ASTM D 4747, 
ASTM D 4827, and ASTM D 5910 in Method 311. These ASTM standards cover 
procedures to identify and quantify hazardous air pollutants in paints 
and coatings. The ASTM standards were developed and adopted by the 
American Society for Testing and Materials and may be obtained from 
http://www.astm.org or from the ASTM at 100 Barr Harbor Drive, P.O. Box 
C700, West Conshohocken, PA 19428-2959.
    The EPA proposes to use GPA 2166 and GPA 2174 in Subpart KKKK of 
part 60, which involve procedures for obtaining samples from gaseous 
and liquid fuels, respectively. These GPA standards were developed and 
adopted by the Gas Processors Association and may be obtained from 
https://gpamidstream.org/ or from the Gas Processors Association, 6526 
East 60th Street, Tulsa, OK 74145.
    The EPA proposes to use ISO 10715 in subpart KKKK of part 60. This 
standard involves procedures for obtaining samples from gaseous fuels. 
This standard was developed by the International Organization for 
Standardization and may be obtained from https://www.iso.org/home.html 
or from the ISH Inc., 15 Inverness Way East, Englewood, CO 80112.

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

    The EPA believes that this action is not subject to Executive Order 
12898 (59 FR 7629, February 16, 1994) because it does not establish an 
environmental health or safety standard. This action would correct and 
update existing testing regulations.

    Authority: 23 U.S.C. 101; 42 U.S.C. 7401-7671q.

0
2. Revise sections 1.2, 1.6, 6.2.1(d), and 8.6.6 and Figure 7 in Method 
201A of appendix M to part 51 to read as follows:

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

* * * * *
    Method 201A--Determination of PM10 and PM2.5 
Emissions From Stationary Sources (Constant Sampling Rate Procedure)
* * * * *
    1.2 Applicability. This method addresses the equipment, 
preparation, and analysis necessary to measure filterable PM. You can 
use this method to measure filterable PM from stationary sources only. 
Filterable PM is collected in stack with this method (i.e., the method 
measures materials that are solid or liquid at stack conditions). If 
the gas filtration temperature exceeds 29.4 [deg]C (85 [deg]F), then 
you may use the procedures in this method to measure only filterable PM 
(material that does not pass through a filter or a cyclone/filter 
combination). If the gas filtration temperature exceeds 29.4 [deg]C (85 
[deg]F), and you must measure both the filterable and condensable 
(material that condenses after passing through a filter) components of 
total primary (direct) PM emissions to the atmosphere, then you must 
combine the procedures in this method with the procedures in Method 202 
of appendix M to this part for measuring condensable PM. However, if 
the gas filtration temperature never exceeds 29.4 [deg]C (85 [deg]F), 
then use of Method 202 of appendix M to this part is not required to 
measure total primary PM.
* * * * *
    1.6 Conditions. You can use this method to obtain particle sizing 
at 10 micrometers and or 2.5 micrometers if you sample within 80 and 
120 percent of isokinetic flow. You can also use this method to obtain 
total filterable particulate if you sample within 90 to 110 percent of 
isokinetic flow, the number of sampling points is the same as required 
by Method 5 of appendix A-3 to part 60 or Method 17 of appendix A-6 to 
part 60, and the filter temperature is within an acceptable range for 
these methods. For Method 5, the acceptable range for the filter 
temperature is generally 120 [deg]C (248 [deg]F) unless a higher or 
lower temperature is specified. The acceptable range varies depending 
on the source, control technology and applicable rule or permit 
condition. To satisfy Method 5 criteria, you may need to remove the in-
stack filter and use an out-of-stack filter and recover the PM in the 
probe between the PM2.5 particle sizer and the filter. In 
addition, to satisfy Method 5 and Method 17 criteria, you may need to 
sample from more than 12 traverse points. Be aware that this method 
determines in-stack PM10 and PM2.5 filterable 
emissions by sampling from a required maximum of 12 sample points, at a 
constant flow rate through the train (the constant flow is necessary to

[[Page 68077]]

maintain the size cuts of the cyclones), and with a filter that is at 
the stack temperature. In contrast, Method 5 or Method 17 trains are 
operated isokinetically with varying flow rates through the train. 
Method 5 and Method 17 require sampling from as many as 24 sample 
points. Method 5 uses an out-of-stack filter that is maintained at a 
constant temperature of 120 [deg]C (248 [deg]F). Further, to use this 
method in place of Method 5 or Method 17, you must extend the sampling 
time so that you collect the minimum mass necessary for weighing each 
portion of this sampling train. Also, if you are using this method as 
an alternative to a test method specified in a regulatory requirement 
(e.g., a requirement to conduct a compliance or performance test), then 
you must receive approval from the authority that established the 
regulatory requirement before you conduct the test.
* * * * *
    6.2.1 * * *
    (d) Petri dishes. For filter samples; glass, polystyrene, or 
polyethylene, unless otherwise specified by the Administrator.
* * * * *
    8.6.6 Sampling Head. You must preheat the combined sampling head to 
the stack temperature of the gas stream at the test location (28 [deg]C, 50 [deg]F). This will heat the sampling 
head and prevent moisture from condensing from the sample gas stream.

Sec.  60.534  What test methods and procedures must I use to determine 
compliance with the standards and requirements for certification?

* * * * *
    (h) The approved test laboratory must allow the manufacturer, the 
manufacturer's approved third-party certifier, the EPA and delegated 
state regulatory agencies to observe certification testing. However, 
manufacturers must not involve themselves in the conduct of the test 
after the pretest burn has begun. Communications between the 
manufacturer and laboratory or third-party certifier personnel 
regarding operation of the wood heater must be limited to written 
communications transmitted prior to the first pretest burn of the 
certification test series. During certification tests, the manufacturer 
may communicate with the third-party certifier, and only in writing to 
notify them that the manufacturer has observed a deviation from proper 
test procedures by the laboratory. All communications must be included 
in the test documentation required to be submitted pursuant to Sec.  
60.533(b)(5) and must be consistent with instructions provided in the 
owner's manual required under Sec.  60.536(g).

(i) and paragraphs (i)(1) and (2) to read as follows:

Sec.  60.2110  What operating limits must I meet and by when?

* * * * *
    (i) If you use a PM CPMS to demonstrate continuing compliance, you 
must establish your PM CPMS operating limit and determine compliance 
with it according to paragraphs (i)(1) through (5) of this section:
    (1) Determine your operating limit as the average PM CPMS output 
value recorded during the performance test or at a PM CPMS output value 
corresponding to 75 percent of the emission limit if your PM 
performance test demonstrates compliance below 75 percent of the 
emission limit. You must verify an existing or establish a new 
operating limit after each repeated performance test. You must repeat 
the performance test annually and reassess and adjust the site-specific 
operating limit in accordance with the results of the performance test:
    (i) Your PM CPMS must provide a 4-20 milliamp output, or digital 
equivalent, and the establishment of its relationship to manual 
reference method measurements must be determined in units of milliamps;
    (ii) Your PM CPMS operating range must be capable of reading PM 
concentrations from zero to a level equivalent to at least two times 
your allowable emission limit. If your PM CPMS is an auto-ranging 
instrument capable of multiple scales, the primary range of the 
instrument must be capable of reading PM concentration from zero to a 
level equivalent to two times your allowable emission limit; and
    (iii) During the initial performance test or any such subsequent 
performance test that demonstrates compliance with the PM limit, record 
and average all milliamp output values, or their digital equivalent, 
from the PM CPMS for the periods corresponding to the compliance test 
runs (e.g., average all your PM CPMS output values for three 
corresponding Method 5 or Method 29 test runs).
    (2) If the average of your three PM performance test runs are below 
75 percent of your PM emission limit, you must calculate an operating 
limit by establishing a relationship of PM CPMS signal to PM 
concentration using the PM CPMS instrument zero, the average PM CPMS 
output values corresponding to the three compliance test runs, and the 
average PM concentration from the Method 5 or Method 29 performance 
test with the procedures in (i)(1) through (5) of this section:

8. Amend Sec.  60.2145 by revising the introductory text to paragraph 
(j) and paragraph (y)(3) to read as follows:

Sec.  60.2145  How do I demonstrate continuous compliance with the 
emission limitations and the operating limits?

* * * * *

[[Page 68079]]

    (j) For waste-burning kilns, you must conduct an annual performance 
test for particulate matter, cadmium, lead, carbon monoxide, dioxins/
furans and hydrogen chloride as listed in table 7 of this subpart, 
unless you choose to demonstrate initial and continuous compliance 
using CEMS, as allowed in paragraph (u) of this section. If you do not 
use an acid gas wet scrubber or dry scrubber, you must determine 
compliance with the hydrogen chloride emissions limit using a HCl CEMS 
according to the requirements in paragraph (j)(1) of this section. You 
must determine compliance with the mercury emissions limit using a 
mercury CEMS or an integrated sorbent trap monitoring system according 
to paragraph (j)(2) of this section. You must determine compliance with 
nitrogen oxides and sulfur dioxide using CEMS. You must determine 
continuing compliance with the particulate matter emissions limit using 
a PM CPMS according to paragraph (x) of this section.
* * * * *
    (y) * * *
    (3) For purposes of determining the combined emissions from kilns 
equipped with an alkali bypass or that exhaust kiln gases to a coal 
mill that exhausts through a separate stack, instead of installing a 
CEMS or PM CPMS on the alkali bypass stack or in-line coal mill stack, 
the results of the initial and subsequent performance test can be used 
to demonstrate compliance with the relevant emissions limit. A 
performance test must be conducted on an annual basis (no later than 13 
calendar months following the previous performance test).

adding paragraph (p) to read as follows:

Sec.  60.2210  What information must I include in my annual report?

    The annual report required under Sec.  60.2205 must include the 
items listed in paragraphs (a) through (p) of this section. If you have 
a deviation from the operating limits or the emission limitations, you 
must also submit deviation reports as specified in Sec. Sec.  60.2215, 
60.2220, and 60.2225:

\1\ All emission limitations are measured at 7 percent oxygen (except for CEMS and integrated sorbent trap
  monitoring system data during startup and shutdown), dry basis at standard conditions. For dioxins/furans, you
  must meet either the Total Mass Basis limit or the toxic equivalency basis limit.
\2\ In lieu of performance testing, you may use a CEMS or, for mercury, an integrated sorbent trap monitoring
  system, to demonstrate initial and continuing compliance with an emissions limit, as long as you comply with
  the CEMS or integrated sorbent trap monitoring system requirements applicable to the specific pollutant in
  Sec.  Sec.   60.2145 and 60.2165. As prescribed in Sec.   60.2145(u), if you use a CEMS or integrated sorbent
  trap monitoring system to demonstrate compliance with an emissions limit, your averaging time is a 30-day
  rolling average of 1-hour arithmetic average emission concentrations.
\3\ Alkali bypass and in-line coal mill stacks are subject to performance testing only, as specified in Sec.
  60.2145(y)(3). They are not subject to the CEMS, integrated sorbent trap monitoring system, or CPMS
  requirements that otherwise may apply to the main kiln exhaust.

12. Amend Sec.  60.2675 by revising the introductory text to paragraph 
(i) and paragraphs (i)(1) and (2) to read as follows:

Sec.  60.2675  What operating limits must I meet and by when?

* * * * *
    (i) If you use a PM CPMS to demonstrate continuing compliance, you 
must establish your PM CPMS operating limit and determine compliance 
with it according to paragraphs (i)(1) through (5) of this section:
    (1) During the initial performance test or any such subsequent 
performance test that demonstrates compliance with the PM limit, record 
all hourly average output values (milliamps, or the digital signal 
equivalent) from the PM CPMS for the periods corresponding to the test 
runs (e.g., three 1-hour average PM CPMS output values for three 1-hour 
test runs):
    (i) Your PM CPMS must provide a 4-20 milliamp output, or the 
digital signal equivalent, and the establishment of its relationship to 
manual reference method measurements must be

[[Page 68081]]

determined in units of milliamps or digital bits;
    (ii) Your PM CPMS operating range must be capable of reading PM 
concentrations from zero to a level equivalent to at least two times 
your allowable emission limit. If your PM CPMS is an auto-ranging 
instrument capable of multiple scales, the primary range of the 
instrument must be capable of reading PM concentration from zero to a 
level equivalent to two times your allowable emission limit; and
    (iii) During the initial performance test or any such subsequent 
performance test that demonstrates compliance with the PM limit, record 
and average all milliamp output values, or their digital equivalent, 
from the PM CPMS for the periods corresponding to the compliance test 
runs (e.g., average all your PM CPMS output values for the three 
corresponding Method 5 or Method 29 p.m. test runs).
    (2) If the average of your three PM performance test runs are below 
75 percent of your PM emission limit, you must calculate an operating 
limit by establishing a relationship of PM CPMS signal to PM 
concentration using the PM CPMS instrument zero, the average PM CPMS 
output values corresponding to the three compliance test runs, and the 
average PM concentration from the Method 5 or Method 29 performance 
test with the procedures in (i)(1) through (5) of this section:

13. Amend Sec.  60.2710 by revising paragraphs (j) and (y)(3) to read 
as follows:

Sec.  60.2710  How do I demonstrate continuous compliance with the 
amended emission limitations and the operating limits?

* * * * *
    (j) For waste-burning kilns, you must conduct an annual performance 
test for the pollutants (except mercury and hydrogen chloride if no 
acid gas wet scrubber or dry scrubber is used) listed in table 8 of 
this subpart, unless you choose to demonstrate initial and continuous 
compliance using CEMS, as allowed in paragraph (u) of this section. If 
you do not use an acid gas wet scrubber or dry scrubber, you must 
determine compliance with the hydrogen chloride emissions limit using a 
HCl CEMS according to the requirements in paragraph (j)(1) of this 
section. You must determine compliance with the mercury emissions limit 
using a mercury CEMS or an integrated sorbent trap monitoring system 
according to paragraph (j)(2) of this section. You must determine 
continuing compliance with particulate matter using a PM CPMS according 
to paragraph (x) of this section.
* * * * *
    (y) * * *
    (3) For purposes of determining the combined emissions from kilns 
equipped with an alkali bypass or that exhaust kiln gases to a coal 
mill that exhausts through a separate stack, instead of installing a 
CEMS or PM CPMS on the alkali bypass stack or in-line coal mill stack, 
the results of the initial and subsequent performance test can be used 
to demonstrate compliance with the relevant emissions limit. A 
performance test must be conducted on an annual basis (no later than 13 
calendar months following the previous performance test).
0
14. Revise Sec.  60.2715 to read as follows:

Sec.  60.2715  By what date must I conduct the annual performance test?

    You must conduct annual performance tests no later than 13 calendar 
months following the previous performance test.

    8.1.3 Leak-Check Procedures.
    8.1.3.1 Leak Check of Metering System Shown in Figure 4-1. That 
portion of the sampling train from the pump to the orifice meter should 
be leak-checked prior to initial use and after each shipment. Leakage 
after the pump will result in less volume being recorded than is 
actually sampled. The following procedure is suggested (see Figure 5-2 
of Method 5): Close the main valve on the meter box. Insert a one-hole 
rubber stopper with rubber tubing attached into the orifice exhaust 
pipe. Disconnect and vent the low side of the orifice manometer. Close 
off the low side orifice tap. Pressurize the system to 13 to 18 cm (5 
to 7 in.) water column by blowing into the rubber tubing. Pinch off the 
tubing and observe the manometer for one minute. A loss of pressure on 
the manometer indicates a leak in the meter box; leaks, if present, 
must be corrected.
    8.1.3.2 Pretest Leak Check. A pretest leak check of the sampling 
train is recommended, but not required. If the pretest leak check is 
conducted, the following procedure should be used.
    8.1.3.2.1 After the sampling train has been assembled, turn on and 
set the filter and probe heating systems to the desired operating 
temperatures. Allow time for the temperatures to stabilize. If a Viton 
A O-ring or other leak-free connection is used in assembling the probe 
nozzle to the probe liner, leak-check the train at the sampling site by 
plugging the nozzle and pulling a 380 mm (15 in.) Hg vacuum.
    Note: A lower vacuum may be used, provided that it is not exceeded 
during the test.
    8.1.3.2.2 Leak-check the train by first plugging the inlet to the 
filter holder and pulling a 380 mm (15 in.) Hg vacuum (see note in 
section 8.1.3.2.1). Then connect the probe to the train, and leak-check 
at approximately 25 mm (1 in.) Hg vacuum; alternatively, the probe may 
be leak-checked with the rest of the sampling train, in one step, at 
380 mm (15 in.) Hg vacuum. Leakage rates in excess of 4 percent of the 
average sampling rate or 0.00057 m\3\/min (0.020 cfm), whichever is 
less, are unacceptable.
    8.1.3.2.3 Start the pump with the bypass valve fully open and the 
coarse adjust valve completely closed. Partially open the coarse adjust 
valve, and slowly close the bypass valve until the desired vacuum is 
reached. Do not reverse the direction of the bypass valve, as this will 
cause water to back up into the filter holder. If the desired vacuum is 
exceeded, either leak-check at this higher vacuum, or end the leak 
check and start over.
    8.1.3.2.4 When the leak check is completed, first slowly remove the 
plug from the inlet to the probe, filter holder, and immediately turn 
off the vacuum pump. This prevents the water in the impingers from 
being forced backward into the filter holder and the silica gel from 
being entrained backward into the third impinger.
    8.1.3.3 Leak Checks During Sample Run. If, during the sampling run, 
a component (e.g., filter assembly or impinger) change becomes 
necessary, a leak check shall be conducted immediately before the 
change is made. The leak check shall be done according to the procedure 
outlined in section 8.1.3.2 above, except that it shall be done at a 
vacuum equal to or greater than the maximum value recorded up to that 
point in the test. If the leakage rate is found to be no greater than 
0.00057 m\3\/min (0.020 cfm) or 4 percent of the average sampling rate 
(whichever is less), the results are acceptable, and no correction will 
need to be applied to the total volume of dry gas metered; if, however, 
a higher leakage rate is obtained, either record the leakage rate and 
plan to correct the sample volume as shown in section 12.3 of Method 5, 
or void the sample run.
    Note: Immediately after component changes, leak checks are 
optional. If such leak checks are done, the procedure outlined in 
section 8.1.3.2 above should be used.
    8.1.3.4 Post-Test Leak Check. A leak check of the sampling train is 
mandatory at the conclusion of each sampling run. The leak check shall 
be performed in accordance with the procedures outlined in section 
8.1.3.2, except that it shall be conducted at a vacuum equal to or 
greater than the maximum value reached during the sampling run. If the 
leakage rate is found to be no greater than 0.00057 m\3\ min (0.020 
cfm) or 4 percent of the average sampling rate (whichever is less), the 
results are acceptable, and no correction need be applied to the total 
volume of dry gas metered. If, however, a higher leakage rate is 
obtained, either record the leakage rate and correct the sample volume 
as shown in section 12.3 of Method 5, or void the sampling run.
* * * * *
    8.1.4.2 At the end of the sample run, close the coarse adjust 
valve, remove the probe and nozzle from the stack, turn off the pump, 
record the final DGM meter reading, and conduct a post-test leak check, 
as outlined in section 8.1.3.4.

Method 5--Determination of Particulate Matter Emissions From Stationary 
Sources

* * * * *
    6.1.1.8 Condenser. The following system shall be used to determine 
the stack gas moisture content: Four impingers connected in series with 
leak-free ground glass fittings or any similar leak-free 
noncontaminating fittings. The first, third, and fourth impingers shall 
be of the Greenburg-Smith design, modified by replacing the tip with a 
1.3 cm (\1/2\ in.) ID glass tube extending to about 1.3 cm (\1/2\ in.) 
from the bottom of the flask. The second impinger shall be of the 
Greenburg-Smith design with the standard tip. Modifications (e.g., 
using flexible connections between the impingers, using materials other 
than glass, or using flexible vacuum lines to connect the filter holder 
to the condenser) may be used, subject to the approval of the 
Administrator. The first and second impingers shall contain known 
quantities of water (Section 8.3.1), the third shall be empty, and the 
fourth shall contain a known weight of silica gel, or equivalent 
desiccant. A temperature sensor, capable of measuring temperature to 
within 1 [deg]C (2 [deg]F) shall be placed at the outlet of the fourth 
impinger for monitoring purposes. Alternatively, any system that cools 
the sample gas stream and allows measurement of the water condensed and 
moisture leaving the condenser, each to within 0.5 g may be used, 
subject to the approval of the Administrator. An acceptable technique 
involves the measurement of condensed water either gravimetrically and 
the determination of the moisture leaving the condenser by: (1) 
Monitoring the temperature and pressure at the exit of the condenser 
and using Dalton's law of partial pressures; or (2) passing the sample 
gas stream through a tared silica gel (or equivalent desiccant) trap 
with exit gases kept below 20 [deg]C (68 [deg]F) and determining the 
weight gain. If means other than silica gel are used to determine the 
amount of moisture leaving the condenser, it is recommended that silica 
gel (or equivalent) still be used between the condenser system and pump 
to prevent moisture condensation in the pump and metering devices and 
to avoid the need to make corrections for moisture in the metered 
volume.
    Note: If a determination of the PM collected in the impingers is 
desired in addition to moisture content, the impinger system described 
above shall be used, without modification. Individual States or control 
agencies requiring this information shall be contacted as to the sample 
recovery and analysis of the impinger contents.
* * * * *
    6.2.4 Petri dishes. For filter samples; glass, polystyrene, or 
polyethylene, unless otherwise specified by the Administrator.
    6.2.5 Balance. To measure condensed water to within 0.5 g at a 
minimum.
* * * * *
    8.1.2 Check filters visually against light for irregularities, 
flaws, or pinhole leaks. Label filters of the proper diameter on the 
back side near the edge using numbering machine ink. As an alternative, 
label the shipping containers (glass, polystyrene or polyethylene petri 
dishes), and keep each filter in its identified container at all times 
except during sampling.
* * * * *
    8.7.6.4 Impinger Water. Treat the impingers as follows: Make a 
notation of any color or film in the liquid catch. Measure the liquid 
that is in the first three impingers by weighing it to within 0.5 g at 
a minimum by using a balance. Record the weight of liquid present. This 
information is required to calculate the moisture content of the 
effluent gas. Discard the liquid after measuring and recording the 
weight, unless analysis of the impinger catch is required (see Note, 
section 6.1.1.8). If a different type of

[[Page 68088]]

condenser is used, measure the amount of moisture condensed 
gravimetrically.

    8.5 Post-Run System Bias Check and Drift Assessment.
    How do I confirm that each sample I collect is valid? After each 
run, repeat the system bias check or 2-point system calibration error 
check (for dilution systems) to validate the run. Do not make 
adjustments to the measurement system (other than to maintain the 
target sampling rate or dilution ratio) between the end of the run and 
the completion of the post-run system bias or system calibration error 
check. Note that for all post-run system bias or 2-point system 
calibration error checks, you may inject the low-level gas first and 
the upscale gas last, or vice-versa. If conducting a relative accuracy 
test or relative accuracy test audit, consisting of nine runs or more, 
you may risk sampling for up to three runs before performing the post-
run bias or system calibration error check provided you pass this test 
at the conclusion of the group of three runs. A failed post-run bias or 
system calibration error check in this case will invalidate all runs 
subsequent to the last passed check. When conducting a performance or 
compliance test, you must perform a post-run system bias or system 
calibration error check after each individual test run.

conduct a system performance check as detailed in section 8.3.1 to 
validate the sampling train components and procedures. Although this 
test is optional, it would significantly reduce the possibility of 
rejecting tests as a result of failing the post-test performance check. 
At the completion of the pretest system performance check, insert the 
sampling probe into the test port making certain that no dilution air 
enters the stack though the port. Condition the entire system with 
sample for a minimum of 15 minutes before beginning analysis. If the 
sample is diluted, determine the dilution factor as in section 10.4 of 
Method 15.

    11.1 Analysis. Inject aliquots of the sample into the GC/FPD 
analyzer for analysis. Determine the concentration of SO2

    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 
must be maintained between 120 and 134 [deg]C (248 and 273 [deg]F). The 
temperature should be monitored throughout a sampling run to ensure 
that the desired temperature is maintained. It is important to maintain 
a temperature around the probe and filter in this range 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 under 
reporting of these emissions. The applicable subparts may specify 
alternative higher temperatures.)

    8.1.5 Sampling Train Operation. Follow the general procedure given

around the probe, filter (and cyclone, if used) between 120 and 134 
[deg]C (248 and 273 [deg]F) since it is extremely difficult to purge 
acid gases off these components. (These components are not 
quantitatively recovered and hence any collection of acid gases on 
these components would result in potential under reporting these 
emissions. The applicable subparts may specify alternative higher 
temperatures.) For each run, record the data required on a data sheet 
such as the one shown in Method 5, Figure 5-3. If the condensate 
impinger becomes too full, it may be emptied, recharged with 50 ml of 
0.1 N H2SO4, and replaced during the sample run. The condensate emptied 
must be saved and included in the measurement of the volume of moisture 
collected and included in the sample for analysis. The additional 50 ml 
of absorbing reagent must also be considered in calculating the 
moisture. Before the sampling train integrity is compromised by 
removing the impinger, conduct a leak-check as described in Method 5, 
section 8.4.2.

Performance Specification 6--Specifications and Test Procedures for 
Continuous Emission Rate Monitoring Systems in Stationary Sources

* * * * *
    13.1 Calibration Drift. Since the CERMS includes analyzers for 
several measurements, the CD shall be determined separately for each 
analyzer in terms of its specific measurement. The calibration for each 
analyzer associated with the measurement of flow rate shall not drift 
or deviate from each reference value of flow rate by more than 3 
percent of the respective high-level reference value over the CD test 
period (e.g., seven-day) associated with the pollutant analyzer. The CD 
specification for each analyzer for which other PSs have been 
established (e.g., PS 2 for SO2 and NOX), shall 
be the same as in the applicable PS.
    13.2 CERMS Relative Accuracy. Calculate the CERMS Relative Accuracy 
using Eq. 2-6 of section 12 of Performance Specification 1. The RA of 
the CERMS shall be no greater than 20 percent of the mean value of the 
RM's test data in terms of the units of the emission standard, or in 
cases where the average emissions for the test are less

[[Page 68092]]

than 50 percent of the applicable standard, substitute the emission 
standard value in the denominator of Eq. 2-6 in place of the RM.

Performance Specification 9--Specifications and Test Procedures for Gas 
Chromatographic Continuous Emission Monitoring Systems in Stationary 
Sources

* * * * *
    7.2 Performance Audit Gas. Performance Audit Gas is an independent 
cylinder gas or cylinder gas mixture. A certified EPA audit gas shall 
be used, when possible. A gas mixture containing all the target 
compounds within the calibration range and certified by EPA's 
Traceability Protocol for Assay and Certification of Gaseous 
Calibration Standards may be used when EPA performance audit materials 
are not available. If a certified EPA audit gas or a traceability 
protocol gas is not available, use a gas manufacturer standard accurate 
to 2 percent.
* * * * *
    8.3 Seven (7)-Day Calibration Error (CE) Test Period. At the 
beginning of each 24-hour period, set the initial instrument set points 
by conducting a multi-point calibration for each compound. The multi-
point calibration shall meet the requirements in section 13.1, 13.2, 
and 13.3. Throughout the 24-hour period, sample and analyze the stack 
gas at the sampling intervals prescribed in the regulation or permit. 
At the end of the 24-hour period, inject the calibration gases at three 
concentrations for each compound in triplicate and determine the 
average instrument response. Determine the CE for each pollutant at 
each concentration using Equation 9-2. Each CE shall be <=10 percent. 
Repeat this procedure six more times for a total of 7 consecutive days.
    8.4 Performance Audit Test Periods. Conduct the performance audit 
once during the initial 7-day CE test and quarterly thereafter. 
Performance Audit Tests must be conducted through the entire sampling 
and analyzer system. Sample and analyze the EPA audit gas(es) (or the 
gas mixture) three times. Calculate the average instrument response. 
Results from the performance audit test must meet the requirements in 
sections 13.3 and 13.4.
* * * * *
    10.1 Multi-Point Calibration. After initial startup of the GC, 
after routine maintenance or repair, or at least once per month, 
conduct a multi-point calibration of the GC for each target analyte. 
Calibration is performed at the instrument independent of the sample 
transport system. The multi-point calibration for each analyte shall 
meet the requirements in sections 13.1, 13.2, and 13.3.
* * * * *
    10.2 Daily Calibration. Once every 24 hours, analyze the mid-level 
calibration standard for each analyte in triplicate. Calibration is 
performed at the instrument independent of the sample transport system. 
Calculate the average instrument response for each analyte. The average 
instrument response shall not vary more than 10 percent from the 
certified concentration value of the cylinder for each analyte. If the 
difference between the analyzer response and the cylinder concentration 
for any target compound is greater than 10 percent, immediately inspect 
the instrument making any necessary adjustments, and conduct an initial 
multi-point calibration as described in section 10.1.
* * * * *
    13.1 Calibration Error (CE). The CEMS must allow the determination 
of CE at all three calibration levels. The average CEMS calibration 
response must not differ by more than 10 percent of calibration gas 
value at each level after each 24-hour period and after any triplicate 
calibration response check.
    13.2 Calibration Precision and Linearity. For each triplicate 
injection at each concentration level for each target analyte, any one 
injection shall not deviate more than 5 percent from the average 
concentration measured at that level. When the CEMS response is 
evaluated over three concentration levels, the linear regression curve 
for each organic compound shall be determined using Equation 9-1 and 
must have an r\2\ >= 0.995.
* * * * *
    13.4 Performance Audit Test Error. Determine the error for each 
average pollutant measurement using the Equation 9-2 in section 12.3. 
Each error shall be less than or equal to 10 percent of the cylinder 
gas certified value. Report the audit results including the average 
measured concentration, the error and the certified cylinder 
concentration of each pollutant as part of the reporting requirements 
in the appropriate regulation or permit.

63, appendix A, or ASTM D6348-12 including all annexes, as applicable, 
as the RMs for HCl measurement. Obtain and analyze RM audit samples, if 
they are available, concurrently with RM test samples according to the 
same procedure specified for performance tests in the general 
provisions of the applicable part. If Method 26 is not specified in an 
applicable subpart of the regulations, you may request approval to use 
Method 26 in appendix A-8 to this part as the RM on a site-specific 
basis under Sec. Sec.  63.7(f) or 60.8(b). Other RMs for moisture, 
O2, etc., may be necessary. Conduct the RM tests in such a 
way that they will yield results representative of the emissions from 
the source and can be compared to the CEMS data.

    1.1 Applicability. This method is applicable for determination of 
most compounds designated by the U.S. Environmental Protection Agency 
as volatile hazardous air pollutants (HAP's) (See Reference 1) that are 
contained in paints and coatings. Styrene, ethyl acrylate, and methyl 
methacrylate can be measured by ASTM D 4827-03 or ASTM D 4747-02. 
Formaldehyde can be measured by ASTM D 5910-05 or ASTM D 1979-91. 
Toluene diisocyanate can be measured in urethane prepolymers by ASTM D 
3432-89. Method 311 applies only to those volatile HAP's which are 
added to

[[Page 68095]]

the coating when it is manufactured, not to those that may form as the 
coating cures (reaction products or cure volatiles). A separate or 
modified test procedure must be used to measure these reaction products 
or cure volatiles in order to determine the total volatile HAP 
emissions from a coating. Cure volatiles are a significant component of 
the total HAP content of some coatings. The term ``coating'' used in 
this method shall be understood to mean paints and coatings.

1.0 Scope and Application

    This method is applicable to the determination of formaldehyde, CAS 
Registry number 50-00-0, from stationary sources in the mineral wool 
and wool fiber glass industries. High purity water is used to collect 
the formaldehyde. The formaldehyde concentrations in the stack samples 
are determined using the modified pararosaniline method. Formaldehyde 
can be detected as low as 8.8 x 10-\10\ lbs/cu ft (11.3 
ppbv) or as high as 1.8 x 10-\3\ lbs/cu ft (23,000,000 
ppbv), at standard conditions over a 1 hour sampling period, sampling 
approximately 30 cu ft.
