Stationary Combustion Turbines
Emissions Information Collection
Test Procedures, Methods and Reporting Requirements for the
Section 114 Request for Stationary Combustion Turbines
This document provides an overview of the required testing, approved sampling and analysis
methods, target pollutants and units of measure, and reporting requirements for stationary
combustion turbines that are required to provide emission test data to the U.S. Environmental
Protection Agency (EPA) under Clean Air Act (CAA) section 114 (42 U.S.C. 7414). The
purpose for this testing is to gather data on air pollutant emissions from stationary combustion
turbines in this source category to inform the EPA's decision-making process for regulation of
these sources. All recipients must complete and submit test results no later than 9 months after
receipt of this request. The document is organized as follows:
1.0 Testing Procedures and Methods
2.0 How to Report Data
3.0 How to Submit Data
4.0 Contact Information for Questions on Test Plan and Reporting
1.0 Testing Procedures and Methods
The EPA requires emissions and other test data for several pollutants, including specific
hazardous air pollutants (HAP), criteria pollutants, and potential surrogate groups. If the EPA is
requesting that you complete emissions testing, the cover letter of this CAA section 114 request
will include a list of emissions sources selected for testing at your facility. For stationary
combustion turbines as specified in Enclosure 1 of your section 114 cover letter, you must
perform an emissions test for some combination of pollutants {i.e., simultaneous measurements
per group) and diluents according to the test protocols and test methods for air emissions
presented in Section 1.1 of this document.
You may have conducted tests for some of these pollutants already. If you have conducted any of
the requested groups of tests {i.e., any complete set of tests required to be conducted
simultaneously as described in Footnote 2 to Table 1) in the past 5 years, these test data may be
submitted for this section 114 request according to the procedures in Section 2 and no additional
testing for those pollutants is required, provided the test data you submit is representative of your
operations and the previous testing met the testing requirements specified in this document {e.g.,
test method, sample volume) and contains all required data elements.
Please refer to the Stationary Combustion Turbines website (https://www.epa.gov/stationary-
sources-air-pollution/stationary-combustion-turbines-national-emission-standards) for additional
-------
testing information. Please note that you do not have to submit a test plan to the EPA for
approval prior to testing; however, we recommend that you prepare a test plan for your own use
to assist in the planning of the test program and to verify that you address all of the testing and
reporting requirements specified in this document. Please note that you also must report your
process and emissions testing data using the EPA's Electronic Reporting Tool (ERT), where
applicable. You are directed to the ERT website (https://www.epa.gov/electronic-reporting-air-
emissions/electronic-reporting-tool-ert) for a more complete and interactive description of the
ERT, list of methods currently supported by the ERT, and a link to download the ERT. Some of
the emissions test methods listed in this document are supported in the ERT while others are not
(e.g., U.S. EPA Method 320).
You must follow all of the procedures as specified in the test methods, including the quality
assurance and quality control measures, and document the results in the ERT and in any test
report provided to the EPA. For this program, you do not need to obtain audit materials from
your state or local agency or from the EPA. You may apply any third-party audit materials you
have on hand and document the results, but you are not required to do so.
If Enclosure 1 of your section 114 cover letter is missing any stationary combustion turbines
subject to 40 CFR part 63, subpart YYYY, or if any of the stationary combustion turbines
included in Enclosure 1 are misclassified (e.g., units are not in the appropriate test group or are
not subject to subpart YYYY), please contact Melanie King (see Section 4.0 of this document).
If a facility has units that are required to be tested according to your section 114 cover letter but
you are unable to respond to an item exactly as requested and you are unable to test another
similar unit, please explain why you cannot respond and/or provide any information you believe
may be related in a submission to Melanie King (see Section 4.0 of this document) within
35 days of postmark date of your section 114 cover letter. NOTE: The EPA reserves all of its
enforcement rights provided by CAA section 113, including the right to bring a claim in the U.S.
District Court to enforce the CAA section 114 obligation to comply with all the requests
described in this document.
1.1 Stack Test Methods
You must follow the stack test method procedures described in this section for each stationary
combustion turbine that you are required to test.
The owner/operator of the stationary combustion turbine must certify that the unit tested was
operating in a normal and representative manner during the performance test. The
owner/operator must also certify that it operated the air pollution control device (APCD), if any,
on the unit tested in accordance with manufacturers' specifications and requirements for proper
operation during the emissions testing.
1.1.1 Sample Location
You should collect emissions samples for the identified pollutants downstream of the last
relevant APCD (i.e., stack or other point representing the composition of the flue gases at the
exit to the atmosphere), unless otherwise indicated. You must use U.S. EPA Method 1 or 1A of
Appendix A-l to 40 CFR Part 60, as applicable, to select the locations and number of traverse
2
-------
points for sampling for the tests in this section. See https://www.epa.gov/emc/method-l-
samplevelocitv-traverses and https ://www. epa. gov/emc/method-1 a-small-ducts for copies of the
methods and guidance information for sampling situations not meeting Method 1 criteria.
1.1.2 Emissions Measurement Methods
Table 1 summarizes the testing required to be performed for each type of stationary combustion
turbine. When possible, testing for each of the pollutants listed in Table 1 should be conducted
simultaneously for your stationary combustion turbine. However, if simultaneous testing is not
possible, then you must at least conduct the tests for formaldehyde and carbon monoxide
simultaneously and conduct the tests for filterable particulate matter (PM) and HAP metals
testing simultaneously. It is not necessary to test the different pollutants in any particular order.
The primary reason for concurrent testing is to obtain a clear understanding about the overall
HAP emissions profile from each emission process point. A second reason is to gather
information that will help us evaluate the correlations of emissions of one pollutant to another
pollutant, to potentially establish surrogate relationships. For example, the metal HAP tests and
PM tests from the APCD or main stack are required to be done at the same time. Where a
predictable relationship between metal HAP and PM exists, a surrogate relationship can be
established for compliance purposes. Tests that are required to be concurrent under this test
request that are not done in this manner may be considered invalid and may need to be
repeated.
Table 1 also presents a list of the test methods to use for completing the required tests. For copies
of the U.S. EPA test methods and additional information, please refer to the EPA's Emission
Measurement Center (EMC) website, https://www.epa.gov/emc.
Report all pollutant emission data as indicated in Table 1. Report the results of your emissions
tests according to the directions provided in Section 2.0 of this document.
Unless otherwise specified, each pollutant emissions test should consist of at least seven test runs
for the sampling duration and/or volume indicated for each specified unit.

-------
During testing, you should monitor, record and report process data for each test run. For process
data that you record during testing, make clear the correlation between emissions measurements
and process data (e.g., identify Method 5, run 1 for the associated process data on the process
data details tab of the ERT or be sure to enter the process data on the correct row of the
Stationary Combustion Turbines Testing Supplement, as applicable; see Section 2.2 for more
information on the Stationary Combustion Turbines Testing Supplement).
The process data to be documented during each test run (as applicable) include:
• Fuel type (e.g., natural gas, propane, fuel oil), and heat input (British thermal units per
hour (Btu/hr)).
• Actual fuel feed rate during test (based on HHV) and permitted fuel feed rate (based on
HHV) (MMBtu/hr). You must explain the procedure that you used (e.g., EPA Method
19) to determine the actual fuel feed rate and provide the calculation in the notes field for
this data element in the Microsoft® Excel template that is used to report results to the
EPA.
• Turbine load (percent).
• Emission unit operating temperature (°F).
• Operating parameters relevant for the APCD, including, for example, oxidation catalyst
inlet temperature.
You must keep the following records for 3 years:
• Documentation that each emissions test was conducted in accordance with the enclosed
sampling protocol; and
• The results of each emissions test.
1.2 Ensuring Data Quality of the Source Tests Performed
While in most cases we are not specifying numerical minimum detection levels for the tests to be
performed, we have specified the testing conditions and methods required, including minimum
test run sample volumes or times when appropriate, which we believe will provide data of a
quality sufficient for decision making.
We remind source owners and testers of the CAA section 114(a)(1) requirement to provide
information requested for the development of emissions standards using methods that provide
data necessary for the decisions. This information includes data of quality sufficient to support
those decisions. For the most part, we can identify test methods and procedures that will satisfy
those decision-making needs (e.g., minimum sampling times). In other cases, we recognize that
the source owner's or tester's selection of test procedures or equipment could bear significantly
on the quality of the data. See Appendix A of this document for information regarding guidance
for calculating and reporting values measured below method detection levels.
We believe that the CAA is clear that it is incumbent on the source owner/operator and the tester
to apply methods and procedures that result in data quality necessary for our decisions, including
providing for the lowest possible detection limits considering practical and reasonable
limitations. For example, source owners/operators and testers should not automatically choose to
5
-------
use low or medium quality equipment for testing (e.g., for cost reasons) if high quality
equipment is reasonably available. We will review test reports in light of this expectation and
will be particularly mindful of whether the testing procedures applied are representative of the
highest reasonably expected capabilities (e.g., comparing reported minimum measurement
detection levels between tests and testers).
On completion of your required tests, please provide a complete test report, including
appendices. A complete test report includes the following information, at a minimum:
• General identification information for facility including a mailing address; the actual
facility address; the owner or operator, responsible official, or an appropriate
representative (where applicable) and an email address for this person; and the
appropriate Federal Registry System (FRS) number for the facility);
• A brief process description, including a flow diagram clearly showing the turbine and the
sampling site;
• A complete unit description, including the unit ID, the stationary combustion turbine
subcategory, the appropriate source classification code (SCC), the latitude and longitude
of the emission point being tested (decimal degrees to five decimal points), and the
maximum permitted process rate (where applicable);
• Emissions control measures in use during the test, including:
o APCD description and APCD ID (if applicable)
o A description of any pollution prevention or other HAP emission reduction
approaches being implemented during the test program;
• Any process data and control device monitoring data required in this document;
• Sampling site description; description of sampling and analysis procedures and any
modifications to standard procedures; quality assurance procedures;
• Description of any deviations from the test methods or other anomalies that occurred with
the process or APCD operations during the test;
• Run-by-run emission data in the units of measure specified in Table 1;
• Stack or exhaust gas flow rate (as determined using U.S. EPA Method 2 or alternatives)
at the time of and during the emissions test, as appropriate;
• Example calculations of all applicable stack gas parameters, emission rates and analytical
results, as applicable;
• Raw field sampling data sheets and notes;
• Laboratory data and analysis reports, including instrument calibrations and raw analytical
data;
• Chain-of-custody documentation;
• Explanation of laboratory data qualifiers;
• Quality assurance and quality control activities performed;
• Identification information for the company conducting the performance test, including a
contact person and his/her email address; and
• Any other information required by the test method, a relevant standard, or the
Administrator.
If we believe that a source owner/operator or tester has failed to meet the requirement of the
CAA to provide data of sufficient quality or quantity for our decisions, we can and will request
6
-------
additional measurements that require the use of improved testing procedures. The permitted
facility representative and the testing company representative must complete the Final
Verification form of the ERT certifying that the report is accurate and complete.
2.0 How to Report Data
The method for reporting the results of any testing and monitoring requests depend on the type of
tests and the type of methods used to complete the test requirements. This section discusses the
requirements for reporting the data.
2.1 Reporting Stack Test Data within ERT
For testing conducted using one of the methods listed in Table 2, you must report your data using
the EPA's ERT Version 6.0 or newer. ERT is a Microsoft Access® database application available
at https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert. If you
are not a registered owner of Microsoft Access®, you can install the runtime version of
Microsoft Access® from the link on the ERT website in order to run the ERT Application. The
ERT must be downloaded onto your computer prior to data entry. A series of Microsoft Excel®-
based templates can be used to assist with the upload of the field sampling data. These templates
are also available on the ERT website. After completing the data entry into the ERT, you will
also need to attach supporting documentation to the Attachments module of the ERT. The
supporting documentation should include: complete lab reports, chain of custodies, field data and
sample/moisture recovery sheets, CEMS raw data, calibrations of equipment, gases and
instruments, QA/QA data, audit sample results (if applicable), and field notes. If a full test report
is attached in the ERT, any of the preceding supporting documentation included in the full test
report does not need to also be individually attached. The ERT database file should be
transmitted to EPA using one of the options described in Section 3.0 of this document.
The list of fields within the ERT with notes explaining whether the field is required or optional
can be found on the Stationary Combustion Turbines website (https://www.epa.gov/stationary-
sources-air-pollution/stationary-combustion-turbines-national-emission-standards).

*For data entry purposes- if PM is collected by Method 29, the data entry is only performed once by selecting PM as a
compound/analyte under Method 29.
7
-------
2.2 Reporting Other Test Data Not Listed in ER T
At present, of the methods required by this request, only the methods shown in Table 2 are
supported by the ERT. For testing you conducted using a method not currently supported by the
ERT (including the use of a plant CEMS), you must report the results of this test in the
Stationary Combustion Turbines Testing Supplement. The Stationary Combustion Turbines
Testing Supplement can be downloaded from the Stationary Combustion Turbines website
(https://www.epa.gov/stationarv-sources-air-pollution/stationary-combustion-turbines-national-
emi s si on- standards).
You must report the results of each test on the appropriately labeled form corresponding to the
specific tests requested at your emissions source. If you conducted testing at more than one
source at a facility using methods not currently supported by the ERT, follow the instructions in
the Stationary Combustion Turbines Testing Supplement, found on the Stationary Combustion
Turbines website. For plant CEMS data used in lieu of EPA Method 10, the test run average is
calculated as the average of the one-minute averages collected over the duration of the test run.
After completing the Stationary Combustion Turbines Testing Supplement, you must also submit
an electronic copy of the emission test report (PDF format preferred) for air sampling. If the
complete emission test report is attached to the ERT file containing the associated flow rate
measurements, a second copy does not need to be submitted. Both the completed Stationary
Combustion Turbines Testing Supplement and the emission test report(s) should be included as
attachments to the ERT file for simultaneous tests done using methods supported by the ERT (at
a minimum, EPA Methods 1 through 3) and transmitted to the EPA as described in Section 3.0
of this document. For plant CEMS data used in lieu of EPA Method 10, the one-minute averages
during each of the seven test runs must be included as an attachment in the ERT and the test run
averages reported in the testing supplement.
2.3 Guidance for Calculating and Reporting Measurements Less Than In-Stack Method
Detection Levels for Emissions Data Submitted in Response to CAA Section 114
Requests
See Appendix A to this document for guidance on calculating and reporting measurements less
than detection levels for emissions data collection programs.
3.0 How to Submit Data
As explained in the previous section, where applicable, you must report your data using the ERT.
If the ERT does not support a particular pollutant or method, you must report your data using the
data reporting tools we provide and include the additional file as an attachment to your ERT
submittal. When you are ready to submit your data to the EPA, compile electronic copies of all
nonconfidential* requested files (including files that do not contain any Confidential Business
Information (CBI) as well as files that have been redacted to remove CBI) and email the files to
the address shown in your section 114 cover letter.
8
-------
* Please Note: The EPA's procedures for handling CBI are described in Enclosure 4 of the letter
accompanying the section 114 request. If you claim that some of the information being submitted
is CBI,1 DO NOT use the method described above to submit your CBI. You must create a
separate submission containing all files associated with this request (i.e., all information claimed
to be CBI and non-CBI portions combined). Clearly mark the materials submitted with the words
"Confidential Business Information." Send these files under separate cover only to Ms. Tiffany
Purifoy at one of the CBI addresses shown in your section 114 cover letter.
For the security of your data, the EPA recommends sending your confidential files to the EPA's
CBI Office as described in Section 6 of Enclosure 4 of your section 114 cover letter. If you
compile the materials onto a CD, DVD, or USB flash drive to mail to the CBI office, the EPA
recommends sending it via registered U.S. Mail using return receipt requested, Federal Express,
or other method for which someone must provide a signature upon receipt.

Appendix A
Guidance for Calculating and Reporting Measurements Less Than
In-Stack Method Detection Levels for Emissions Data
Submitted in Response to Section 114 Requests
Please identify the status of measured values relative to detection levels in the Stationary
Combustion Turbines Testing Supplement or in the ERT using the descriptions below. For each
reported emissions value, insert the appropriate flag (BDL, DLL, or ADL) in the Flag line of the
ERT or in the Flag column of the Stationary Combustion Turbines Testing Supplement for the
row that corresponds to that run.
• BDL (below detection level) - all analytical values used to calculate and report an in-
stack emissions value are less than the laboratory's reported detection level(s);
• DLL (detection level limited) - at least one but not all values used to calculate and report
an in-stack emissions value are less than the laboratory's reported detection level(s); or
• ADL (above detection level) - all analytical values used to calculate and report an in-
stack emissions value are greater than the laboratory's reported detection level(s).
When reporting and calculating individual test run data:
• You must use the approach specified in the test method for calculation and determination
of the analytical method detection level (MDL). If the method does not specify the
approach and calculation of the MDL, you must determine the MDL in accordance with
the procedures specified in Section 15 of Method 301 (located in Appendix A of 40 CFR
part 63).
• For analytical data reported from the laboratory as above the MDL, include the ADL flag
in the Outlet Detect Flag column of the Stationary Combustion Turbines Testing
Supplement as appropriate or in the Comments line in the ERT.
• For analytical data reported from the lab as BDL, "non-detect" or "below detection
level":
o Include a brief description of the procedures used to determine the analytical
detection and in-stack detection level:
¦ In the Analytical Comments column of the Stationary Combustion
Turbines Testing Supplement; or
¦ In the Comments line of Lab Data tab in the Run Data Details in the ERT.
o Describe these procedures completely in the complete test report, including the
measurements made, the standards used, and the statistical procedures applied,
o Calculate the in-stack emissions rate for any analytical result reported as BDL
using the relevant MDL, sampling volumes, and other relevant run-specific
parameters (such as O2 or flow rate). The reported value must assume that the
analyte is present at the full MDL value,
o Report the calculated emissions concentration or rate result:
-------
¦ As a numerical value {i.e., no brackets or < symbol) in the Stationary
Combustion Turbines Testing Supplement, columns Outlet Mass and/or
Outlet Concentration as appropriate; select the appropriate flag in the
Outlet Detect Flag column as appropriate; or
¦ As a numerical value in the ERT with the appropriate flag in the
Comments line.
o Report as numerical values {i.e., no brackets or < symbol) any analytical data
measured above the MDL, including any data between the MDL and a laboratory-
specific reporting or quantification level {i.e., flag as ADL).
• For pollutant measurements composed of multiple components or fractions {e.g., mercury
and other metals sampling trains), when the result for the value for any component is
measured below the MDL:
o Calculate in-stack emissions rate or concentrations as outlined above for each
component or fraction;
o Sum the measured values and/or calculated values (using the MDL as outlined
above) for all of the components or fractions; and
o Report the sum of all components or fractions:
¦ As a numerical value (i.e., no brackets or < symbol) in the Stationary
Combustion Turbines Testing Supplement; columns Outlet Mass and/or
Outlet Concentration as appropriate and select the appropriate flag in the
Outlet Detect Flag column as appropriate; or
¦ As a numerical value in the ERT with the appropriate flag in the
Comments line.
¦ If all components or fractions are BDL, the appropriate flag is BDL. If the
components or fractions are a mix of BDL, DLL, and ADL, then the
appropriate flag is DLL. [Note: If all components or fractions are above
the MDL, the appropriate flag is ADL.]
o In addition to reporting the sum of the components or fractions, report the
individual component or fraction values for each run if the Stationary Combustion
Turbines Testing Supplement or ERT format allows. If the Stationary Combustion
Turbines Testing Supplement or ERT format does not allow reporting of the
individual components or fractions {i.e., the format allows reporting only a single
sum value):
¦ For the Stationary Combustion Turbines Testing Supplement, for each
applicable run, report the appropriate flag in the Outlet Detect Flag
column and report the values for the measured or MDL value for each
component or fraction as used in the calculations {e.g., 0.036, [<0.069],
1.239, [<0.945] for a four-fraction sample) in the Analytical Comments
column; or
¦ For the ERT, next to the sum reported as above, report on the Comments
line the appropriate flag and the measured or MDL value for each
component or fraction as used in the calculations {e.g., 0.036, [<0.069],
1.239, [<0.945] for a four-fraction sample).
A-2
-------
• For measurements conducted using the instrumental test methods (e.g., Methods 3A):
o Record gaseous concentration values as measured including negative values and
flag as ADL; do not report as BDL.
o Calculate and report in-stack emissions rates using these measured values,
o Include relevant information relative to calibration gas values or other technical
qualifiers for measured values in the Comments line in the ERT or Method
Comments line column of the Stationary Combustion Turbines Testing
Supplement.
