Revisions to Testing Regulations for Air Emission Sources

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: This action proposes corrections and updates to regulations 
for source testing of emissions. The proposed rule includes corrections 
to testing provisions that contain inaccuracies, updates to outdated 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.

I. General Information

A. Does this action apply to me?

    The proposed amendments apply to industries that are subject to the 
current provisions of parts 51, 60, 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 makes corrections and revisions to source test methods, 
performance specifications (PS), quality assurance/quality control (QA/
QC) procedures, and testing 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.

II. Background

    The EPA catalogs errors and corrections, as well as necessary 
revisions to test methods, PS, QA/QC procedures, and associated 
regulations in 40 CFR parts 51, 60, and 63 and periodically updates and 
revises these provisions. The most recent updates and revisions were 
promulgated on August 30, 2016 (81 FR 59800). 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.

III. Summary of Proposed Amendments

    The following amendments are being proposed.

A. Method 201A of Appendix M of Part 51

    In Method 201A, in section 12.5, the denominator of equation 24 
would be corrected.

B. Method 204 of Appendix M of Part 51

    In Method 204, in section 8.2, the statement regarding equation 
204-2 would be corrected to ``The NEAR must be <=0.05.''

C. Method 205 of Appendix M of Part 51

    In Method 205, section 2.1.1 would be revised to allow the use of 
National Institute of Standards and Technology (NIST)-traceable 
transfer standards to calibrate the gas dilution system because these 
standards are widely available and provide the accuracy necessary to 
perform the calibration. Section 2.1.1 would also be revised to require 
testers to report the results of the calibration of the dilution system 
to enable the regulatory authority to review this information.

D. General Provisions (Subpart A) of Part 60

    In the General Provisions of part 60, section 60.17(h) would be 
revised to add American Society for Testing and Materials (ASTM) D6216-
12 to the list of incorporations by reference and to re-number the 
remaining consensus standards that are incorporated by reference in 
alpha-numeric order.

E. Fossil-Fuel-Fired Steam Generators (Subpart D) Part 60

    In subpart D, the allowed filter temperature in section 
60.46(b)(2)(i) would be revised from 160 <plus-minus>14 [deg]C to 160 
<plus-minus>5 [deg]C resulting in increased precision of the filterable 
PM measurements.

F. Electric Utility Steam Generating Units (Subpart Da) Part 60

    In subpart Da, the allowed filter temperature in section 60.50Da 
(b)(1)(ii)(A) would be revised from 160 <plus-minus>14 [deg]C to 160 
<plus-minus>5 [deg]C resulting in increased precision of the filterable 
PM measurements.

G. Industrial-Commercial-Institutional Steam Generating Units (Subpart 
Db) Part 60

    In subpart Db, the allowed filter temperature in section 
60.46b(d)(4) would be revised from 160 <plus-minus>14 [deg]C to 160 
<plus-minus>5 [deg]C resulting in increased precision of the filterable 
PM measurements.

[[Page 3638]]

H. Small Industrial-Commercial-Institutional Steam Generating Units 
(Subpart Dc) Part 60

    In subpart Dc, the allowed filter temperature in section 
60.45c(a)(5) would be revised from 160 <plus-minus>14 [deg]C to 160 
<plus-minus>5 [deg]C resulting in increased precision of the filterable 
PM measurements.

I. Municipal Waste Combustors for Which Construction Is Commenced After 
December 20, 1989 and on or Before September 20, 1994 (Subpart Ea) Part 
60

    In subpart Ea, the allowed filter temperature in section 
60.58a(b)(3) would be revised from 160 <plus-minus>14 [deg]C to 160 
<plus-minus>5 [deg]C resulting in increased precision of the filterable 
PM measurements.

J. Glass Manufacturing Plants (Subpart CC) Part 60

    In subpart CC, the allowed filter temperature in section 60.293(f) 
would be revised from 120 <plus-minus>14 [deg]C to 120 <plus-minus>5 
[deg]C resulting in increased precision of the filterable particulate 
matter (PM) measurements. The allowed filter temperature in section 
60.296(d)(2) would be revised from 177 <plus-minus>14 [deg]C to 177 
<plus-minus>5 [deg]C resulting in increased precision of the filterable 
PM measurements.

K. New Residential Wood Heaters, New Residential Hydronic Heaters and 
Forced-Air Furnaces Part 60

    In subpart QQQQ, in Method 28WHH, in section 13.5.1, equation 8 
would be corrected.

L. Method 2B of Appendix A-1 of Part 60

    In Method 2B, in section 12.1, the definition of ambient carbon 
dioxide concentration would be revised because the global monthly mean 
(CO<INF>2</INF>)<INF>a</INF> concentration varies over time. Also, a 
website link would be added to the definition.

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

    The allowed filter temperature in Method 5, sections 2.0, 6.1.1.2, 
6.1.1.6, 6.1.1.7, and 8.5 would be revised from 120 <plus-minus>14 
[deg]C to 120 <plus-minus>5 [deg]C resulting in increased precision of 
the filterable PM measurements. Section 6.1.1.9 would be revised to 
allow the use of a single temperature sensor in lieu of two temperature 
sensors on the dry gas meter as allowed by Technical Information 
Document 19 (TID-19) and the approved broadly applicable alternative, 
ALT-117 (see https://www.epa.gov/emc).

N. Method 5B of Appendix A-3 of Part 60

    The allowed filter temperature in Method 5B, sections 2.0, 6.1, and 
8.2 would be revised from 160 <plus-minus>14 [deg]C to 160 <plus-
minus>5 [deg]C resulting in increased precision of the filterable PM 
measurements. Section 11.0 would be revised to replace the reference to 
Method 5, section 11.0 with specific analytical procedures and to 
report the results using Figure 5B-1 for complete data review. Section 
17.0 would be revised to delete the word ``Reserved'' from the title, 
and Figure 5B-1 (Analytical Data Sheet) would be added.

O. Method 5I of Appendix A-3 of Part 60

    In Method 5I, sections 2.1 and 8.5.2.2 would be revised to tighten 
the allowed filter temperature from 120 <plus-minus>14 [deg]C to 120 
<plus-minus>5 [deg]C resulting in increased precision of the filterable 
PM measurements.

P. Method 7 of Appendix A-4 of Part 60

    In Method 7, sections 10.1.2 and 11.3 reference erroneous sections; 
the correct sections would be inserted.

Q. Method 8 of Appendix A-4 of Part 60

    In Method 8, sections 6.1.1.1 through 6.1.1.4 would be renumbered 
to 6.1.1.2 through 6.1.1.5; a new section 6.1.1.1 would be added to 
clarify the requirements that apply to the probe nozzle; and Figure 8-1 
(Sulfuric Acid Sampling Train) would be corrected.

R. Method 18 of Appendix A-6 of Part 60

    In Method 18, in section 13.1, the erroneous paragraph (c) 
designation would be re-designated as (b).

S. Method 22 of Appendix A-7 of Part 60

    In Method 22, sections 11.2.1 and 11.2.2 would be revised to allow 
digital photography to be used for a subset of the recordkeeping 
requirements. Section 11.2.3 would be added to allow digital 
photographic records. Note that ALT-109 (see https://www.epa.gov/emc) 
is the associated broadly applicable alternative that allows the use of 
digital photographs for specific recordkeeping requirements.

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

    In Method 26, section 6.2.2 would be revised to allow the use of 
glass sample storage containers as an option to allow flexibility and 
to be consistent with Method 26A.

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

    In Method 26A, section 6.2.1 would be revised to remove the 
language regarding sample storage containers. We have determined that 
high-density polyethylene is an acceptable material for sample storage 
containers in addition to the currently allowed glass. Therefore, we 
would allow both high-density polyethylene and glass in a new section 
6.2.4.

V. Test Method 28WHH of Appendix A-8 of Part 60

    In Test Method 28WHH, equation 8 in section 13.5.1 would be 
corrected.

W. Performance Specification 1 of Appendix B of Part 60

    In Performance Specification 1, references to ASTM D6216-98 (in 
sections 2.1, 3.1, 6.1, 8.1(1), 8.1(3)(ii), 8.2(1), 8.2(2), 8.2(3), 
9.0, 12.1, 13.1, 13.2, and 16.0 reference 8. will be replaced with ASTM 
D6216-12. Note: If the initial certification of the continuous opacity 
monitoring system (COMS) has already occurred using D6216-98, D6216-03, 
or D6216-07, it will not be necessary to recertify using D6216-12.

X. Performance Specification 2 of Appendix B of Part 60

    In Performance Specification 2, section 13.2 would be replaced with 
a table that indicates the relative accuracy performance 
specifications.

Y. Performance Specification 3 of Appendix B of Part 60

    In Performance Specification 3, the two sentences in section 12.0 
that read, ``Calculate the arithmetic difference between the RM and the 
CEMS output for each run. The average difference of the nine (or more) 
data sets constitute the RA.'' would be deleted; these two sentences 
are no longer necessary since equations 3-1 and 3-2 would be moved from 
section 13.2 to section 12.0.

Z. Performance Specification 11 of Appendix B of Part 60

    In Performance Specification 11, section 13.1, the word ``average'' 
erroneously exists in the second sentence and would be deleted.

AA. Performance Specification 15 of Appendix B of Part 60

    In Performance Specification 15, section 13.0 would be added as 
``Method Performance (Reserved).''

BB. Performance Specification 18 of Appendix B of Part 60

    In Performance Specification 18, in section 11.8.7, the last 
sentence would

[[Page 3639]]

be revised to clarify the duration of the drift check. In Table 1, the 
erroneous acronym ``NO<INF>2</INF>'' would be replaced with ``NO.'' In 
the appendix of Performance Specification 18, the inadvertently omitted 
reserved section 12.0 would be added.

CC. Procedure 1 of Appendix F of Part 60

    In Procedure 1, in section 5.1.2 (1), the sentence immediately 
following the table that reads, ``Challenge the CEMS three times at 
each audit point, and use the average of the three responses in 
determining accuracy.'' would be replaced with, ``Inject each of the 
audit gases, three times each for a total of six injections. Inject the 
gases in such a manner that the entire CEMS is challenged. Do not 
inject the same gas concentration twice in succession.'' In section 
5.1.2 (3), the reference to EPA's traceability protocol for gaseous 
calibration standards would be updated, and the language regarding the 
use of EPA Method 205 for dilution of audit gases would be clarified.

DD. General Provisions (Subpart A) of Part 63

    Sections 63.7(g)(2), 63.7(g)(2)(v), and 63.8(e)(5)(i) of the 
General Provisions (subpart A) of part 63 would be revised to require 
the reporting of specific test data for continuous monitoring system 
performance evaluation tests and ongoing QA tests. These data elements 
would be required regardless of the format of the report, i.e., 
electronic or paper. These modifications will ensure that performance 
evaluation and quality assurance test reporting include all data 
necessary for the compliance authority to assess and assure the quality 
of the reported data and that the reported information describes and 
identifies the specific unit covered by the evaluation test report.

EE. Wool Fiberglass Manufacturing (Subpart NNN) Part 63

    In subpart NNN, the allowed filter temperature in Sec.  
63.1385(a)(5) would be revised from 120 <plus-minus>14 [deg]C to 120 
<plus-minus>5 [deg]C resulting in increased precision of the filterable 
PM measurements.

FF. Major Sources: Industrial, Commercial, and Institutional Boilers 
and Process Heaters (Subpart DDDDD) Part 63

    In Table 6 of subpart DDDDD, row 1.f. would be revised to allow the 
use of EPA SW-846-7471B (for liquid samples) in addition to EPA SW-846-
7470A for measuring mercury to allow flexibility.

GG. Coal- and Oil-Fired Electric Utility Steam Generating Units 
(Subpart UUUUU) Part 63

    In subpart UUUUU, the allowed filter temperature in Sec.  
63.10010(h)(7)(i)(1) would be revised from 160 <plus-minus>14 [deg]C to 
160 <plus-minus>5 [deg]C resulting in increased precision of the 
filterable PM measurements. In Table 5, Method 5I would be allowed as a 
test method option because Method 5I is designed for low PM 
application.

HH. Method 303 of Appendix A of Part 63

    In Method 303, section 12.4, equation 303-3 would be corrected by 
inserting ``where y = '' in front of the equation.

II. Method 308 of Appendix A of Part 63

    In Method 308, deionized distilled water would replace the aqueous 
n-proponal solution; the affected sections are 2.0, 7.2.2, 7.2.3.3, and 
11.3.2. Section 7.2.2, which defines the aqueous n-proponal solution, 
would be removed. Section 8.1.2 would be revised to require a leak 
check prior to the sampling run (in addition to after the sampling run) 
for QA purposes; requiring a leak check prior to the sampling run would 
potentially save time and money. In section 9.1, methanol spike 
recovery check would be added as a QC measure in Table 9.1. In section 
12.1, variables used in equations 308-4 and 308-5 would be added and 
section 12.5, which includes equations 308-4 and 308-5, would be added. 
In section 13.0, the title ``Reserved'' would be replaced with ``Method 
Performance'' and QA requirements would be added to be consistent with 
other methods.

JJ. Method 320 of Appendix A of Part 63

    In section 8.2.2.4, the denominator in equation 2 would be 
corrected from P<INF>SS</INF> to P<INF>S</INF>. In section 9.2.3, the 
word ``where'' in the statement ``Calculate the dilution ratio using 
the tracer gas as follows: where:'' would be deleted. Also in section 
9.2.3, ``dir'' on the definition of spike is inadvertently 
superscripted and would be subscripted.

KK. Method 323 of Appendix A of Part 63

    In Method 323, section 12.9, the denominator in equation 323-8 
would be corrected.

LL. Method 325A of Appendix A of Part 63

    In Method 325A, section 8.2.1.3 would be revised to clarify that 
only one extra sampling site is required near known sources of volatile 
organic compounds (VOCs) when the source is within 50 meters of the 
boundary and the source is located between two monitors. The label 
under Figure 8.1 would be corrected from Refinery (20% angle) to 
Refinery (20[deg] angle). Section 8.2.3.2 would be revised to include 
facilities with a monitoring perimeter length equal to 7,315 meters 
(24,000 feet). Section 8.2.3.3 would be added to provide clarification 
and an equivalent procedure in Option 2 (linear distance between sites) 
for site locations that parallel section 8.2.2.2.4 in Option 1 (radial 
distance between sites).

MM. Method 325B of Appendix A of Part 63

    In Method 325B, section 9.3.2 would be revised to correct an error 
in the number of field blank samples required for a sampling period and 
to provide consistency with the sample analysis required in Method 
325B. In sections 9.13 and 11.3.2.5, the erroneous reference to section 
10.6.3 would be corrected to 10.0. Also in section 11.3.2.5, the 
erroneous reference to section 10.9.5 would be corrected to 9.13. 
Section 12.2.2 would be revised to correct the calculation of target 
compound concentrations at standard conditions. Sections 12.2.3 and 
12.2.4 would be deleted because the equations for target concentrations 
are incorrect. Table 17-1 would be revised to add inadvertently omitted 
QC criteria from section 9.3.3.

IV. 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'' under the 
terms of Executive Order (E.O.) 12866 (58 FR 51735, October 4, 1993) 
and is, therefore, not subject to review under Executive Orders 12866 
and 13563 (76 FR 3821, January 21, 2011).

B. 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 improving data quality and providing source testers the 
flexibility to use newly-approved alternative procedures.

[[Page 3640]]

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 do not 
substantively revise the existing information collection requirements 
but rather 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.

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 D6216-12 for continuous opacity monitors in Performance 
Specification 1. The ASTM D6216-12 standard covers the procedure for 
certifying continuous opacity monitors and includes design and 
performance specifications, test procedures, and QA requirements to 
ensure that continuous opacity monitors meet minimum design and 
calibration requirements, necessary in part, for accurate opacity 
monitoring measurements in regulatory environmental opacity monitoring 
applications subject to 10 percent or higher opacity standards.
    The ASTM D6216-12 standard was developed and adopted by the 
American Society for Testing and Materials. The standard 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.

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.

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

* * * * *
    2.0 Summary of Method. Particulate matter is withdrawn 
isokinetically from the source and collected on a glass fiber filter 
maintained at a temperature of 120 <plus-minus>5 [deg]C (248 <plus-
minus>9 [deg]F) or such other temperature as specified by an 
applicable subpart of the standards or approved by the Administrator 
for a particular application. The PM mass, which includes any 
material that condenses at or above the filtration temperature, is 
determined gravimetrically after the removal of uncombined water.
* * * * *
    6.1.1.2 Probe Liner. Borosilicate or quartz glass tubing with a 
heating system capable of maintaining a probe gas temperature during 
sampling of 120 <plus-minus>5 [deg]C (248 <plus-minus>9 [deg]F), or 
such other temperature as specified by an applicable subpart of the 
standards or as approved by the Administrator for a particular 
application. Since the actual temperature at the outlet of the probe 
is not usually monitored during sampling, probes constructed 
according to APTD-0581 and utilizing the calibration curves of APTD-
0576 (or calibrated according to the procedure outlined in APTD-
0576) will be considered acceptable. Either borosilicate or quartz 
glass probe liners may be used for stack temperatures up to about 
480 [deg]C (900 [deg]F); quartz glass liners shall be used for 
temperatures between 480 and 900 [deg]C (900 and 1,650 [deg]F). Both 
types of liners may be used at higher temperatures than specified 
for short periods of time, subject to the approval of the 
Administrator. The softening temperature for borosilicate glass is 
820 [deg]C (1500 [deg]F), and for quartz glass it is 1500 [deg]C 
(2700 [deg]F). Whenever practical, every effort should be made to 
use borosilicate or quartz glass probe liners. Alternatively, metal 
liners (e.g., 316 stainless steel, Incoloy 825 or other corrosion 
resistant metals) made of seamless tubing may be used, subject to 
the approval of the Administrator.
* * * * *
    6.1.1.6 Filter Heating System. Any heating system capable of 
monitoring and maintaining temperature around the filter shall be 
used to ensure the sample gas temperature exiting the filter of 120 
<plus-minus> 5 [deg]C (248 <plus-minus>9 [deg]F) during sampling or 
such other temperature as specified by an applicable subpart of the 
standards or approved by the Administrator for a particular 
application. The monitoring and regulation of the temperature around 
the filter may be done with the filter temperature sensor or another 
temperature sensor.
    6.1.1.7 Filter Temperature Sensor. A temperature sensor capable 
of measuring temperature to within <plus-minus>3 [deg]C (5.4 [deg]F) 
shall be installed so that the sensing tip of the temperature sensor 
is in direct contact with the sample gas exiting the filter. The 
sensing tip of the sensor may be encased in glass, Teflon, or metal 
and must protrude at least \1/2\ in. into the sample gas exiting the 
filter. The filter temperature sensor must be monitored and recorded 
during sampling to ensure a sample gas temperature exiting the 
filter of 120 <plus-minus>5 [deg]C (248 <plus-minus>9 [deg]F), or 
such other temperature as specified by an applicable subpart of the 
standards or approved by the Administrator for a particular 
application.
* * * * *
    6.1.1.9 Metering System. Vacuum gauge, leak-free pump, 
calibrated temperature sensors, dry gas meter (DGM) capable of 
measuring volume to within 2 percent, and related equipment, as 
shown in Figure 5-1. Other metering systems capable of maintaining 
sampling rates within 10 percent of isokinetic and of determining 
sample volumes to within 2 percent may be used, subject to the 
approval of the Administrator. When the metering system is used in 
conjunction with a pitot tube, the system shall allow periodic 
checks of isokinetic rates. The average DGM temperature for use in 
the calculations of Section 12.0 may be obtained by averaging the 
two temperature sensors located at the inlet and outlet of the DGM 
as shown in Figure 5-3 or alternatively from a single temperature 
sensor located at the immediate outlet of the DGM or the plenum of 
the DGM.
* * * * *
    8.5 Sampling Train Operation. During the sampling run, maintain 
an isokinetic sampling rate (within 10 percent of true isokinetic 
unless otherwise specified by the Administrator) and a sample gas 
temperature through the filter of 120 <plus-minus>5 [deg]C (248 
<plus-minus>9 [deg]F) or such other temperature as specified by an 
applicable subpart of the standards or approved by the 
Administrator. Note: After startup of the sampling system, it may 
take several minutes to equilibrate the system and temperature 
reading to within the required temperature threshold.
* * * * *

Method 5B--Determination of Nonsulfuric Acid Particulate Matter 
Emissions From Stationary Sources

* * * * *

2.0 Summary of Method

    Particulate matter is withdrawn isokinetically from the source 
and collected on a glass fiber filter maintained at a temperature of 
160 <plus-minus>5 [deg]C (320 <plus-minus>9 [deg]F). The collected 
sample is then heated in an oven at 160 [deg]C (320 [deg]F) for 6 
hours to volatilize any condensed sulfuric acid that may have been 
collected, and the nonsulfuric acid particulate mass is determined 
gravimetrically.
* * * * *
    6.1 Sample Collection.
    The probe liner heating system and filter heating system must be 
capable of maintaining a sample gas temperature of 160 <plus-minus>5 
[deg]C (320 <plus-minus>9 [deg]F).
* * * * *
    8.2 Probe and Filter Temperatures.
    Maintain the probe outlet and filter temperatures at 160 <plus-
minus>5 [deg]C (320 <plus-minus>9 [deg]F). Note: After start-up of 
the sampling system, it may take several minutes to equilibrate the 
system and temperature reading to within the required temperature 
threshold.
* * * * *

11.0 Analytical Procedure

    11.1 Record and report the data required on a sheet such as the 
one shown in Figure 5B-1.
    11.2 Handle each sample container as follows:
    11.2.1 Container No. 1. Leave the contents in the shipping 
container or transfer the filter and any loose PM from the sample 
container to a tared glass weighing dish. Oven dry the filter sample 
at a temperature of 160 <plus-minus>5 [deg]C (320 <plus-minus>9 
[deg]F) for 6 hours. Cool in a desiccator for 2 hours, and weigh to 
constant weight. Report the results to the nearest 0.1 mg. For the 
purposes of this section, the term ``constant weight'' means a 
difference of no more than 0.5 mg or 1 percent of total weight less 
tare weight, whichever is greater, between two consecutive 
weighings, with no less than 6 hours of desiccation time between 
weighings.
    11.2.2 Container No. 2. Note the level of liquid in the 
container, and confirm on the

[[Page 3643]]

analysis sheet whether leakage occurred during transport. If a 
noticeable amount of leakage has occurred, either void the sample or 
use methods, subject to the approval of the Administrator, to 
correct the final results. Measure the liquid in this container 
either volumetrically to <plus-minus>1 ml or gravimetrically to 
<plus-minus>0.5 g. Transfer the contents to a tared 250 ml beaker, 
and evaporate to dryness at ambient temperature and pressure. Then 
oven dry the probe sample at a temperature of 160 <plus-minus>5 
[deg]C (320 <plus-minus>9 [deg]F) for 6 hours. Cool in a desiccator 
for 2 hours, and weigh to constant weight. Report the results to the 
nearest 0.1 mg.
    11.2.3 Container No. 3. Weigh the spent silica gel (or silica 
gel plus impinger) to the nearest 0.5 g using a balance. This step 
may be conducted in the field.
    11.2.4 Acetone Blank Container. Measure the acetone in this 
container either volumetrically or gravimetrically. Transfer the 
acetone to a tared 250 ml beaker, and evaporate to dryness at 
ambient temperature and pressure. Desiccate for 24 hours, and weigh 
to a constant weight. Report the results to the nearest 0.1 mg.

    Note:  The contents of Container No. 2 as well as the acetone 
blank container may be evaporated at temperatures higher than 
ambient. If evaporation is done at an elevated temperature, the 
temperature must be below the boiling point of the solvent; also, to 
prevent ``bumping,'' the evaporation process must be closely 
supervised, and the contents of the beaker must be swirled 
occasionally to maintain an even temperature. Use extreme care, as 
acetone is highly flammable and has a low flash point.

Method 5I--Determination of Low Level Particulate Emissions From 
Stationary Sources

* * * * *
    2.1. Description. The system setup and operation is essentially 
identical to Method 5. Particulate is withdrawn isokinetically from 
the source and collected on a 47 mm glass fiber filter maintained at 
a temperature of 120 <plus-minus>5 [deg]C (248 <plus-
minus>9[emsp14][deg]F). The PM mass is determined by gravimetric 
analysis after the removal of uncombined water. Specific measures in 
this procedure designed to improve system performance at low 
particulate levels include:

1. Improved sample handling procedures
2. Light weight sample filter assembly
3. Use of low residue grade acetone

    Accuracy is improved through the minimization of systemic errors 
associated with sample handling and weighing procedures. High purity 
reagents, all glass, grease free, sample train components, and light 
weight filter assemblies and beakers, each contribute to the overall 
objective of improved precision and accuracy at low particulate 
concentrations.
* * * * *
    8.5.2.2 Care should be taken to maintain the filter box 
temperature of the paired trains as close as possible to the Method 
required temperature of 120 <plus-minus>5 [deg]C (248 <plus-

KNO<INF>3</INF> working standard solution (1 ml = 100 [mu]g 
NO<INF>2</INF>) to a series of five 50-ml volumetric flasks. To each 
flask, add 25 ml of absorbing solution and 10 ml water. Add 1 N NaOH 
to each flask until the pH is between 9 and 12 (about 25 to 35 
drops). Dilute to the mark with water. Mix thoroughly, and pipette a 
25-ml aliquot of each solution into a separate porcelain evaporating 
dish. Beginning with the evaporation step, follow the analysis 
procedure of section 11.2 until the solution has been transferred to 
the 100-ml volumetric flask and diluted to the mark. Measure the 
absorbance of each solution at the optimum wavelength as determined 
in section 10.1.1.2. This calibration procedure must be repeated on 
each day that samples are analyzed. Calculate the spectrophotometer 
calibration factor as shown in section 12.2.

* * * * *

Performance Specification 1--Specifications and Test Procedures for 
Continuous Opacity Monitoring Systems in Stationary Sources

* * * * *
    2.1 ASTM D6216-12 (incorporated by reference, see Sec.  60.17) 
is the reference for design specifications, manufacturer's 
performance specifications, and test procedures. The opacity monitor 
manufacturer must periodically select and test an opacity monitor, 
that is representative of a group of monitors produced during a 
specified period or lot, for conformance with the design 
specifications in ASTM D6216-12. The opacity monitor manufacturer 
must test each opacity monitor for conformance with the 
manufacturer's performance specifications in ASTM D6216-12. Note: If 
the initial certification of the opacity monitor occurred before 
January 26, 2018 using D6216-98, D6216-03, or D6216-07, it is not 
necessary to recertify using D6216-12.
* * * * *
    3.1 All definitions and discussions from section 3 of ASTM 
D6216-12 are applicable to PS-1.
* * * * *
    6.1 Continuous Opacity Monitoring System. You, as owner or 
operator, are responsible for purchasing an opacity monitor that 
meets the specifications of ASTM D6216-12, including a suitable data 
recorder or automated data acquisition handling system. Example data 
recorders include an analog strip chart recorder or more 
appropriately an electronic data acquisition and reporting system 
with an input signal range compatible with the analyzer output.
* * * * *
    8.1 * * *
    (1) You must purchase an opacity monitor that complies with ASTM 
D6216-12 and obtain a certificate of conformance from the opacity 
monitor manufacturer.
    (2) * * *
    (3) * * *
    (ii) Calibration Error Check. Conduct a three-point calibration 
error test using three calibration attenuators that produce outlet 
pathlength corrected, single-pass opacity values shown in ASTM 
D6216-12, section 7.5. If your applicable limit is less than 10 
percent opacity, use attenuators as described in ASTM D6216-12, 
section 7.5 for applicable standards of 10 to 19 percent opacity. 
Confirm the external audit device produces the proper zero value on 
the COMS data recorder. Separately, insert each calibration 
attenuators (low, mid, and high-level) into the external audit 
device. While inserting each attenuator, (1) ensure that the entire 
light beam passes through the attenuator, (2) minimize interference 
from reflected light, and (3) leave the attenuator in place for at 
least two times the shortest recording interval on the COMS data 
recorder. Make a total of five nonconsecutive readings for each 
attenuator. At the end of the test, correlate each attenuator 
insertion to the corresponding value from the data recorder. 
Subtract the single-pass calibration attenuator values corrected to 
the stack exit conditions from the COMS responses. Calculate the 
arithmetic mean difference, standard deviation, and confidence 
coefficient of the five measurements value using equations 1-3, 1-4, 
and 1-5. Calculate the calibration error as the sum of the absolute 
value of the mean difference and the 95 percent confidence 
coefficient for each of the three test attenuators using equation 1-
6. Report the calibration error test results for each of the three 
attenuators.
* * * * *
    8.2 * * *
    (1) Conduct the verification procedures for design 
specifications in section 6 of ASTM D6216-12.

[[Page 3646]]

    (2) Conduct the verification procedures for performance 
specifications in section 7 of ASTM D6216-12.
    (3) Provide to the owner or operator, a report of the opacity 
monitor's conformance to the design and performance specifications 
required in sections 6 and 7 of ASTM D6216-12 in accordance with the 
reporting requirements of section 9 in ASTM D6216-12.
* * * * *

9.0 What quality control measures are required by PS-1?

    Opacity monitor manufacturers must initiate a quality program 
following the requirements of ASTM D6216-12, section 8. The quality 
program must include (1) a quality system and (2) a corrective 
action program.
* * * * *
    12.1 Desired Attenuator Values. Calculate the desired attenuator 
value corrected to the emission outlet pathlength as follows:
[GRAPHIC] [TIFF OMITTED] TP26JA18.003

Where:

OP<INF>1</INF> = Nominal opacity value of required low-, mid-, or 
high-range calibration attenuators.
OP<INF>2</INF> = Desired attenuator opacity value from ASTM D6216-
12, section 7.5 at the opacity limit required by the applicable 
subpart.
L<INF>1</INF> = Monitoring pathlength.

    13.1 What is the 7-day drift check performance specification? 
Your daily PM CEMS internal drift checks must demonstrate that the 
daily drift of your PM CEMS does not deviate from the value of the 
reference light, optical filter, Beta attenuation signal, or other 
technology-suitable reference standard by more than 2 percent of the 
response range. If your CEMS includes diluent and/or auxiliary 
monitors (for temperature, pressure, and/or moisture) that are 
employed as a necessary part of this performance specification, you 
must determine the calibration drift separately for each ancillary 
monitor in terms of its respective output (see the appropriate 
performance specification for the diluent CEMS specification). None 
of the calibration drifts may exceed their individual specification.

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

    Inject each of the audit gases, three times each for a total of 
six injections. Inject the gases in such a manner that the entire 
CEMS is challenged. Do not inject the same gas concentration twice 
in succession.
    Use of separate audit gas cylinder for audit points 1 and 2. Do 
not dilute gas from audit cylinder when challenging the CEMS.
    The monitor should be challenged at each audit point for a 
sufficient period of time to assure adsorption-desorption of the 
CEMS sample transport surfaces has stabilized.
    (2) * * *
    (3) Use Certified Reference Materials (CRM's) (See Citation 1) 
audit gases that have been certified by comparison to National 
Institute of Standards and Technology (NIST) Standard Reference 
Materials (SRM's) or EPA Protocol Gases following the most recent 
edition of the EPA Traceability Protocol for Assay and Certification 
of Gaseous Calibration Standards (See Citation 2). Procedures for 
preparation of CRM's are described in Citation 1. Procedures for 
preparation of EPA Protocol Gases are described in Citation 2. In 
the case that a suitable audit gas level is not commercially 
available, Method 205 (See Citation 3) may be used to dilute CRM's 
or EPA Protocol Gases to the needed level. The difference between 
the actual concentration of the audit gas and the concentration 
indicated by the monitor is used to assess the accuracy of the CEMS.

2.0 Summary of Method

    A gas sample is extracted from the sampling point in the stack. 
The methanol is collected in deionized distilled water and adsorbed 
on silica gel. The sample is returned to the laboratory where the 
methanol in the water fraction is separated from other organic 
compounds with a gas chromatograph (GC) and is then measured by a 
flame ionization detector (FID). The fraction adsorbed on silica gel 
is extracted with deionized distilled water and is then separated 
and measured by GC/FID.

    7.2.3.3 Methanol Standards for Adsorbent Tube Samples. Prepare a 
series of methanol standards by first pipetting 10 ml of the 
methanol working standard into a 100-ml volumetric flask and 
diluting the contents to exactly 100 ml with deionized distilled 
water. This standard will contain 10 [micro]g/ml of methanol. 
Pipette 5, 15, and 25 ml of this standard, respectively, into four 
50-ml volumetric flasks. Dilute each solution to 50 ml with 
deionized distilled water. These standards will have 1, 3, and 5 
[micro]g/ml of methanol, respectively. Transfer all four standards 
into 40-ml glass vials capped with Teflon[supreg]-lined septa and 
store under refrigeration. Discard any excess solution.
* * * * *
    8.1.2 Leak Check. A leak check before and after the sampling run 
is mandatory. The leak-check procedure is as follows:
    Temporarily attach a suitable (e.g., 0- to 40-ml/min) rotameter 
to the outlet of the DGM, and place a vacuum gauge at or near the 
probe inlet. Plug the probe inlet, pull a vacuum of at least 250 mm 
(10 inch) Hg or the highest vacuum experienced during the sampling 
run, and note the flow rate as indicated by the rotameter. A leakage 
rate in excess of 2 percent of the average sampling rate is 
acceptable.

    Note: Carefully release the probe inlet plug before turning off 
the pump.

13.0 Method Performance

    Since a potential sample may contain a variety of compounds from 
various sources, a specific precision limit for the analysis of 
field samples is impractical. Precision in the range of 5 to 10 
percent relative standard deviation (RSD) is typical for gas 
chromatographic techniques, but an experienced GC operator with a 
reliable instrument can readily achieve 5 percent RSD. For this 
method, the following combined GC/operator values are required.
    (a) Precision. Triplicate analyses of calibration standards fall 
within 5 percent of their mean value.
    (b) Recovery. After developing an appropriate sampling and 
analytical system for the pollutants of interest, conduct the 
following spike recovery procedure at each sampling point where the 
method is being applied.
    i. Methanol Spike. Set up two identical sampling trains. 
Collocate the two sampling probes in the stack. The probes shall be 
placed in the same horizontal plane, where the first probe tip is 
2.5 cm from the outside edge of the other. One of the sampling 
trains shall be designated the spiked train and the other the 
unspiked train. Spike methanol into the impinger, and onto the 
adsorbent tube in the spiked train prior to sampling. The total mass 
of methanol shall be 40 to 60 percent of the mass expected to be 
collected with the unspiked train. Sample the stack gas into the two 
trains simultaneously. Analyze the impingers and adsorbents from the 
two trains utilizing identical analytical procedures and 
instrumentation. Determine the fraction of spiked methanol recovered 
(R) by combining the amount recovered in the impinger and in the 
adsorbent tube, using the equations in section 12.5. Recovery values 
must fall in the range: 0.70 <=R <=1.30. Report the R value in the 
test report.

Method 325A--Volatile Organic Compounds From Fugitive and Area Sources: 
Sampler Deployment and VOC Sample Collection

* * * * *
    8.2.1.3 Extra samplers must be placed near known sources of VOCs 
if the potential emission source is within 50 meters (162 feet) of 
the boundary and the source location is between two monitors. 
Measure the distance (x) between the two monitors and place another 
monitor approximately halfway between (x/2 <plus-minus>10 percent) 
the two monitors. Only one extra sampler is required between two 
monitors to account for the known source of VOCs. For example, in 
Figure 8.1, the facility added three additional monitors (i.e., 
light shaded sampler locations) and in Figure 8.2, the facility 
added two additional monitors to provide sufficient coverage of all 
area sources.

    8.2.3.2 For facilities with a monitoring perimeter length 
greater than or equal to 7,315 meters (24,000 feet), sampling 
locations are spaced 610 <plus-minus>76 meters (2,000 <plus-
minus>250 feet) apart.
    8.2.3.3 Unless otherwise specified in an applicable regulation, 
permit or other requirement, for small disconnected subareas with 
known sources within 50 meters (162 feet) of the monitoring 
perimeter, sampling points need not be placed closer than 152 meters 
(500 feet) apart as long as a minimum of 3 monitoring locations are 
used for each subarea.

Method 325B--Volatile Organic Compounds From Fugitive and Area Sources: 
Sampler Preparation and Analysis

* * * * *
    9.3.2 Field blanks must be shipped to the monitoring site with 
the sampling tubes and must be stored at the sampling location 
throughout the monitoring exercise. The field blanks must be 
installed under a protective hood/cover at the sampling location, 
but the long-term storage caps must remain in place throughout the 
monitoring period (see Method 325A). The field blanks are then 
shipped back to the laboratory in the same container as the sampled 
tubes. Collect at least two field blank samples per sampling period 
to ensure sample integrity associated with shipment, collection, and 
storage.
* * * * *
    9.13 Routine CCV at the Start of a Sequence. Run CCV before each 
sequence of analyses and after every tenth sample to ensure that the 
previous multi-level calibration (see Section 10.0) is still valid.
* * * * *
    11.3.2.5 Whenever the thermal desorption--GC/MS analytical 
method is changed or major equipment maintenance is performed, you 
must conduct a new five-level calibration (see Section 10.0). System 
calibration remains valid as long as results from subsequent CCV are 
within 30 percent of the most recent 5-point calibration (see 
Section 9.13). Include relevant CCV data in the supporting 
information in the data report for each set of samples.
* * * * *
    12.2.2 Determine the equivalent concentrations of compounds in 
atmospheres as follows. Correct target compound concentrations 
determined at the sampling site temperature and atmospheric pressure 
to standard conditions (25 [deg]C and 760 mm mercury) using Equation 
12.5.

Where:

m<INF>meas</INF> = The mass of the compound as measured in the 
sorbent tube ([micro]g).
t = The exposure time (minutes).

[[Page 3656]]

t<INF>ss</INF> = The average temperature during the collection 
period at the sampling site (K).
U<INF>NTP</INF> = The method defined diffusive uptake rate (sampling 
rate) (mL/min).

    Note: Diffusive uptake rates (U<INF>std</INF>) for common VOCs, 
using carbon sorbents packed into sorbent tubes of the dimensions 
specified in Section 6.1, are listed in Table 12.1. Adjust 
analytical conditions to keep expected sampled masses within range 
(see Sections 11.3.1.3 to 11.3.1.5). Best possible method detection 
limits are typically in the order of 0.1 ppb for 1,3-butadiene and 
0.05 ppb for volatile aromatics such as benzene for 14-day 
monitoring. However, actual detection limits will depend upon the 
analytical conditions selected.
