ECMPS Reporting Instructions
Quality Assurance and Certification
1.0 INTRODUCTION: QUALITY ASSURANCE AND CERTIFICATION
About This Document
In the Emissions Collection and Monitoring Plan System (ECMPS), data must be submitted to
the EPA through the Client Tool using extensible-markup language (XML) format. XML files
must contain certain data elements, which are defined in the XML schema. (Note: more
information about the ECMPS XML Schemas can be found in the XML Schema Description
Documents.)
The purpose of the reporting instructions is to provide the necessary information for owners and
operators to meet the reporting requirements for sources affected by:
1) The Acid Rain Program (ARP);
2) The Clean Air Interstate Rule (CAIR); and
3) Other programs required to report data using these XML schemas.
These instructions explain how to report the required data for the applicable regulations. Owners
and operators of units should refer to the applicable regulations for information about what data
are required to be reported.
The Quality Assurance and Certification XML Schema is made up of a root element, complex
elements, and simple elements. A simple element is a single piece of data. A complex element
is a group of simple elements which are logically grouped together. The root element is the base
of the XML schema.
The elements are related to each other in parent-child relationships. The root element is the
parent element of the entire schema. Complex elements are children of the root element, and
complex elements can also be children of other complex elements. If a complex element is
dependent on a parent complex element, the child complex element cannot be included in the
XML file unless the appropriate parent complex element is also included. Figure 1 below
illustrates the relationships between the QA and certification root element and the complex
elements.
This document provides instructions on how the required data should be reported using this data
structure. A separate section is provided for each complex element, its dependencies, and its
simple elements. In addition, there are "specific considerations" that apply to particular types of
monitoring plan configurations.
About QA and Certification Data
QA and certification tests are required for all types of monitoring systems. Test extension or
exemption data indicate variances from prescribed testing requirements or extensions to the
Environmental Protection Agency
Quality Assurance and Certification Reporting Instructions -- Page 1
June 17, 2009
1.0 Introduction: Quality Assurance and Certification
normal QA testing schedule. QA or Certification Events (e.g., monitor replacements), as well as
data elements for submitting an electronic certification application when certifications are
required, are submitted when there is either diagnostic or recertification testing of specific
monitoring systems or components.
QA and Certification Reporting Guidelines
All certification, recertification, and periodic quality assurance tests that affect data validation
must be reported for each primary monitoring system, each redundant backup monitoring
system, and each non-redundant backup system used to report data. For routine QA tests and
diagnostics, the tests results may either be submitted prior to quarterly report submission period,
or with the quarterly emissions file whose hourly data are affected by the test(s). For initial
certification and recertification events, the test results must be submitted to EPA electronically
within 45 days of completing all required tests.
Certification, Recertification and Diagnostic Tests
For initial certifications, recertifications and for certain diagnostic tests, you must submit a
corresponding QA CERTIFICATION EVENT DATA record along with the test results, to indicate the
event that triggered the need for the tests, and which QA tests were required for that event (refer
to the Part 75 Emissions Monitoring Policy Manual). Also you will need to submit a QA
CERTIFICATION EVENT DATA record whenever the conditional data validation procedures in
§75.20(b)(3) are used for routine QA tests.
Aborted Tests
Report all QA tests that are discontinued due to problems with the monitoring systems. Also
report the results of all trial RATA runs and gas injections that do not meet the acceptance
criteria in §75.20(b)(3)(vii)(E). These are regarded as failed tests and trigger out-of-control
periods.
However, do not report the results of tests that are discontinued for reasons unrelated to the
monitors' performance (e.g., due to process upsets, unit outages, or reference method failures).
And do not report the results of trial runs and gas injections that meet the acceptance criteria in
§75.20(b)(3)(vii)(E), which are part of the process of optimizing the performance of a continuous
emissions monitoring system (CEMS). The results of these tests are not used to establish the
validity of hourly emissions data. Simply keep a record of them in the unit's test log.
Entering Test Run Times
When entering test run times for QA tests, use the same frame of reference for entering the end
time as is used for the begin time. ECMPS assumes the run duration to be the difference
between the reported end time and begin time for a run. For example, if a run is begun at
10:20:00 (hr:min:sec) and the run is 21 minutes long, ending at 10:40:59, then the begin time
should be reported as 10:20 and the end time should be entered as 10:41 and not 10:40.

1.0 Introduction: Quality Assurance and Certification
June 17, 2009
Test Calculations
Whenever you perform QA test calculations that involve a number of steps in sequence (e.g.,
linearity error or percent relative accuracy calculations), begin the calculation sequence with the
raw data values reported in the XML (i.e., begin with flow rates that are rounded to the nearest
1000 scfh, gas concentrations that are rounded to the nearest 0.1 ppm, etc.). However, once you
have begun the calculation sequence, do not round off any of the intermediate values (such as the
mean difference, confidence coefficient, (R-A), etc.). Rather retain the full decimal display of
the computer in the intermediate values until the final result is obtained and then round off the
final result. Similarly, do not use rounded intermediate values of statistical terms such as the
standard deviation, mean difference, and confidence coefficient when you perform a bias test of
a CEMS or determine a bias adjustment factor (BAF).

1.2 TEST SUMMARY DATA Elements
Description of Data
Submit one TEST SUMMARY DATA record for each periodic quality assurance, certification, and
diagnostic test submitted as part of the QUALITY ASSURANCE AND CERTIFICATION Test file. This
record summarizes each test performed and provides the test results, the reason for the
conducting each test, and other fundamental information about each test reported (e.g., Span
Scale).
Some tests are quite simple and all the relevant data are reported in the TEST SUMMARY DATA
record. For example, a Data Acquisition and Handling System (DAHS) verification or Primary
Element Inspection (PEI) can be fully described in this record.
On the other hand, most tests have additional data such as gas injections or test runs that must be
linked to the TEST SUMMARY DATA record. The more detailed test data (e.g., calibration
injections for a 7-day calibration error test) are provided in separate complex elements, as listed
below. Some of those dependent complex elements summarize the results that are specific to
one level of a test (e.g., LINEARITY SUMMARY DATA) and have additional detailed records linked
to them in dependent records defined in another complex element (e.g., LINEARITY INJECTION
DATA). These relationships are depicted in the overall schematic (Figure 1) for QA
CERTIFICATION DATA provided on the third page of this document.
In addition to "tests" of monitors or systems, there are also related sets of data that are required to
qualify for a test or to use as a reference ratio for a test. These include the "reference" data for a
flow-to-load check, the baseline data for a fuel-flow-to-load check, and the qualification data
showing that only a single-load flow RATA is required based on the prior year's operation. This
information should also be reported in a TEST SUMMARY DATA record and the related dependent
records.
Dependencies for TEST SUMMARY DATA
The TEST SUMMARY DATA record is dependent on the QUALITY ASSURANCE AND CERTIFICATION
record.

SUMMARY DATA record:

2.1 7-Day Calibration Error Test
Description of Data
Report the details of all 7-day calibration error tests performed for initial certification,
recertification, or diagnostic purposes, using TEST SUMMARY DATA and seven CALIBRATION
INJECTION DATA records. For each day of the 7-day test, report the results of the zero and
upscale gas injections (or flow reference signals) in one CALIBRATION INJECTION DATA record.
All seven CALIBRATION INJECTION DATA records must be linked to the corresponding TEST
SUMMARY DATA record for the 7-day calibration error test being reported.
Specific Considerations
Applicability of 7-Day Calibration Error Tests
● 7-day calibration error tests are reported on a component basis, and need only be reported
once per component, even if that component is shared among multiple systems.
● For moisture monitoring systems consisting of wet- and dry-basis O2 monitors, report
two 7-day calibration tests only if the wet and dry readings are obtained from two
different analyzers.
● For flow monitoring systems comprised of two flow monitor components, perform and
report a 7-day calibration test for each component.
● For dual range monitors, perform and report 7-day calibration tests at each range of the
instrument. Report 7-day calibration error tests for each range of a dual-range analyzer
as separate tests even if both ranges of the analyzer are identified by a single Component
ID.

2.1.1 TEST SUMMARY DATA Elements for 7-Day Calibration
Use the following instructions for completing each element of the TEST SUMMARY DATA section
for the 7-day calibration error test.
Unit ID or Stack Pipe ID
Element Name: UnitID or StackPipeID
Report the Unit ID or Stack Pipe ID that corresponds to the location of the analyzer.
Test Type Code
Element Name: TestTypeCode
Report the test type code as "7DAY."
Monitoring System ID
Element Name: MonitoringSystemID
Leave this field blank. It does not apply to 7-day calibration error tests.
Component ID
Element Name: ComponentID
Report the three-character Component ID assigned to the analyzer.
Span Scale Code
Element Name: SpanScaleCode
Report the analyzer range of the component tested as "H" for high or "L" for low. For single
range monitors, report the scale as "H" unless you are using the default high range option, in
which case report the scale as "L."
Test Number
Element Name: TestNumber
At each monitoring location and for each test type, report a unique test number for each set of
records which comprises a single test. One method of tracking unique test numbers is to use the
Component ID as a prefix to the number. The test number may not be reused at this location for
another 7-day calibration error test.
Test Reason Code
Element Name: TestReasonCode
Report the purpose of the test using the appropriate code from Table 1.

2.1.2 Calibration Injection Data
June 17, 2009
Zero Measured Value
Element Name: ZeroMeasuredValue
Report the response of the gas analyzer to the zero-level calibration gas, in ppm for SO2 and NOx
or in pct for CO2 and O2. For flow monitors, report the response of the monitor to the zero-level
reference signal.
Upscale Measured Value
Element Name: UpscaleMeasuredValue
Report the response of the gas analyzer to the upscale calibration gas, in ppm for SO2 and NOx or
in pct for CO2 and O2. For flow monitors, report the response of the monitor to the upscale
reference signal.
Zero APS Indicator
Element Name: ZeroAPSIndicator
Report whether the zero-level test result was determined using a normal specification "0" or the
alternative performance specification "1" allowed under Part 75.
Appendix A to Part 75 specifies that the calibration error of an O2 or CO2 monitor is always
expressed in percent O2 or CO2, rather than as a percentage of span. This is considered to be the
"normal" calibration error specification; therefore, "0" should be reported in this field. The
alternate performance specification applies only to SO2 and NOx pollutant concentration
monitors that are considered low-emitters of those pollutants and to low-span differential
pressure flow monitors.
Upscale APS Indicator
Element Name: UpscaleAPSIndicator
Report whether the upscale test result was determined using a normal specification "0" or the
alternative performance specification "1" allowed under Part 75. (See discussion under Zero
APS Indicator for more details.)
Zero Calibration Error
Element Name: ZeroCalibrationError
Report the results of the zero-level calibration error test, as required by Part 75.
For SO2, NOx, and flow monitors, express the results either as a percentage of the span value
(i.e., CE), or (for low emitters of SO2 and NOx or for low-span differential pressure flow
monitors) as the absolute value of the difference between the reference value and the measured
value (i.e., R - A). If the calibration error meets the standard specification, report the CE even
though the test would also pass the alternative specification. Only when the result does not pass
the standard specification, but meets the alternative specification, should you report |R - A|. If
the test does not pass either specification, report the CE.
Environmental Protection Agency
Quality Assurance and Certification Reporting Instructions -- Page 19
June 17, 2009
2.1.2 Calibration Injection Data
For low-span differential pressure-type flow monitors using the alternative specification (because
the standard specification was not met): (1) report "0.0" in this field if the value of R - A is <
0.01 inches of water. If the value of R - A is > 0.01 inches of water, report the result as a
percentage of the span value (i.e., CE).
For CO2 and O2 monitors, express the result as an absolute percent CO2 or O2, since the results
are always determined as the absolute value of the difference between the reference value and
the measured value (i.e., |R - A|).
Upscale Calibration Error
Element Name: UpscaleCalibrationError
Report the results of the upscale calibration error test, as required by Part 75. (See the discussion
under Zero Calibration Error for more details.)
Zero Reference Value
Element Name: ZeroReferenceValue
Report the certified (tag) value of the zero-level reference calibration gas, in ppm for SO2 and
NOx or in pct for CO2 and O2. Report the value of the reference signal, in the appropriate units,
for flow monitors.
Upscale Reference Value
Element Name: UpscaleReferenceValue
Report the certified (tag) value of the upscale reference calibration gas, in ppm for SO2 and NOx

2.2 Cycle Time Test
Description of Data
The Cycle Time Test is required for initial certification of a gas CEMS and may be required for
recertification or as a diagnostic test. The Cycle Time Test is not a required periodic quality
assurance test under Appendix B to Part 75. Perform the cycle time test according to the
procedures under 40 CFR Part 75, Appendix A, Section 6.4.
Submit one TEST SUMMARY DATA record and its associated CYCLE TIME SUMMARY DATA record
for each Cycle Time Test performed on a component. Separate CYCLE TIME INJECTION DATA
records are required for the upscale and downscale tests for each analyzer component.
Specific Considerations
Applicability of Cycle Time Tests
● For a dual-range analyzer, report the results of cycle time testing against each range of
the analyzer as two separate tests, even if both ranges of the analyzer are identified by a
single Component ID.
● For a NOx-diluent system, the entire system would be considered out of control (OOC) if
either the NOx or the diluent component fails a cycle time test.
● If you perform an "abbreviated" cycle time test as a diagnostic (refer to the Part 75
Emissions Monitoring Policy Manual), do not report the results of this test electronically.
Keep the data and test results on-site, in a format suitable for audit and inspection.

2.3 Linearity Checks
Description of Data
Report all linearity checks performed for initial certification, recertification, ongoing quality
assurance, or diagnostic purposes using the TEST SUMMARY DATA, LINEARITY SUMMARY DATA,
and LINEARITY INJECTION DATA records. Submit one TEST SUMMARY DATA record for each
linearity check. Include a separate LINEARITY SUMMARY DATA record for each gas level (low,
mid, and high), to report the calculated results for each level. Each LINEARITY SUMMARY DATA
record will include multiple LINEARITY INJECTION DATA records, (one for each calibration gas
injection performed at the gas level for that LINEARITY SUMMARY DATA record). The LINEARITY
INJECTION DATA record is used to report the reference and measured value of each calibration
gas injection.
For a completed linearity check, there will generally be nine LINEARITY INJECTION DATA records
and three corresponding LINEARITY SUMMARY DATA records. However, if a State agency
requires more than the nine EPA-required gas injections for the purposes of their QA program,
you may (optional) report all of the injections using the same test number, although EPA prefers
that you report only the last three injections at each gas level. If more than nine injections are
reported, calculate and report results in the LINEARITY SUMMARY DATA records using only the
last three injections at each gas level. EPA will evaluate only the last three injections at each
level, as indicated by the date and time of the injections. Additional injections will be
disregarded in the Agency's recalculation of the test results.
Specific Considerations
General Requirements for Linearity Checks
● Linearity checks must be performed with the unit in operation.
● Linearity checks are required for the initial certification of all gas monitors.
● Linearity checks are reported on a component basis. Except as noted below for dualrange analyzers. They need only be reported once per component (and range), even if
that component is shared among multiple systems. For example, only one linearity check
need be reported for a CO2 monitor that is a component of both a CO2 monitoring system
and a NOx-diluent monitoring system.
● Gas injections must be performed such that two gas injections are never performed
successively at the same level (i.e., low, mid, or high) during the test.
● Linearity checks are not required for an SO2 or NOx analyzer with a span value of
30 ppm or less. A TEST EXTENSION EXEMPTION DATA record is not required to claim
this exemption.
● Linearity checks for the two ranges of a dual-range analyzer are reported as separate
tests, even if both ranges of the analyzer are identified by a single Component ID.
● If gas monitors are configured such that injection of calibration gases forces all of the
analyzers into the calibration mode, when performing a linearity check on one monitor
Quality Assurance and Certification Reporting Instructions -- Page 34
Environmental Protection Agency
2.3 Linearity Checks
June 17, 2009
this may (e.g., if using tri-blend calibration gases) initiate simultaneous (unscheduled)
linearity checks of the other analyzers. The results of these unscheduled linearity checks
do not have to be reported as long as they meet the linearity error specifications.
However, if the results of these unscheduled tests indicate that a monitoring system is
out-of-control, the results must be reported and the test considered a failed linearity
check.
Linearity Checks for Year-Round Reporters
● If reporting data on a year-round basis, a linearity check of each gas monitor is required
for routine quality assurance in each QA operating quarter (i.e., a calendar quarter with >
168 unit or stack operating hours).
● Limited linearity check exemptions are allowed for "non-QA operating quarters" with
< 168 unit or stack operating hours. However, at least one linearity check is required
every four calendar quarters, regardless of the number of unit or stack operating hours.
● If a required linearity check is not completed by the end of the quarter in which it is due,
a 168 unit/stack operating hour grace period is allowed to perform the test. A TEST
EXTENSION EXEMPTION DATA record is not needed to claim the exemption.
● For dual-range analyzers, you may claim limited linearity check exemptions (up to three
consecutive calendar quarters) on a monitor range that is not used at all during the
quarter. You must report TEST EXTENSION EXEMPTION DATA records to claim these
exemptions.
Linearity Checks for Ozone Season-Only Reporters
● For Subpart H units or stacks that report NOx mass emissions and heat input data only in
the ozone season, a successful linearity check of each component of the primary or
redundant backup CEMS is required prior to each ozone season. The linearities are to be
completed no later than April 30 in the second-quarter and by July 30 in the third-quarter
(see §75.74(c)(3)(ii)).
● The "QA operating quarter" methodology for determining the frequency of linearity
checks does not apply to ozone season-only reporters. For these sources, linearity checks
are required in April and July (see §75.74(c)(3)(ii)).
● The grace period provisions in Section 2.2.4 of Appendix B also do not apply to ozone
season-only reporters. Instead, a 168 unit (or stack) operating hour conditional data
validation period may be used to perform a linearity check that is not completed by the
April 30 or July 30 deadline (see §75.74(c)(2)(ii)(F), (c)(3)(xi), and (c)(3)(xii)). You
must submit a QA CERTIFICATION EVENT DATA record to document the required
probationary calibration error and conditional data validation period.
Environmental Protection Agency
Quality Assurance and Certification Reporting Instructions -- Page 35
June 17, 2009
2.3 Linearity Checks
Aborted, Abbreviated, or Discontinued Linearity Checks
● Report all completed and aborted linearity checks that affect data validation. However,
for ozone season-only reporters, an aborted or failed pre-ozone season (April) linearity
check need not be reported if a subsequent linearity check is passed prior to the start of
the current ozone season.
● An aborted test must be reported and is to be treated as a failed test whenever the test is
discontinued due to a monitor failure or malfunction. Do not report, or treat as a failed
test, a linearity check that is discontinued because of a failure unrelated to instrument
performance, such as a power outage, unit outage, or calibration gas problem. The data
and results of such tests are simply documented in the test log and kept on-site. Also, do
not report the results of trial gas injections that are part of the process of optimizing the
performance of a monitor, when the injections meet the acceptance criteria in
§75.20(b)(3)(vii)(E). Furthermore, for a monitor that is already "out-of-control" due to a
failed or aborted linearity check, do not report the results of any subsequent gas injection
attempts that do not meet the acceptance criteria in §75.20(b)(3)(vii)(E).
● If you perform a three-injection "abbreviated" linearity check as a diagnostic (refer to the
Part 75 Emissions Monitoring Policy Manual), do not report the results of this test
electronically. Keep the data and test results on-site, in a format suitable for audit and
inspection.

2.4 Relative Accuracy Test Audit (RATA)
June 17, 2009
Description of Data
Report all RATAs performed for initial certification, recertification, ongoing quality assurance,
or diagnostic purposes using TEST SUMMARY DATA, RATA DATA, RATA SUMMARY DATA, and
RATA RUN DATA records. Use the RATA RUN DATA record to report the measured data for
each test run. The RATA SUMMARY DATA record is used to report the calculated results and
statistical information for the RATA at the tested operating level. You must include a RATA
SUMMARY DATA record for each operating level tested to satisfy the RATA testing requirement.
Use the RATA DATA record to report the number of load levels that make up the RATA test and
the overall results of the test (i.e., relative accuracy, bias adjustment factor, and RATA test
frequency). There should be a single RATA DATA record for each RATA test.
Only one RATA SUMMARY DATA record (along with its associated RATA RUN DATA records) is
reported for a RATA of a gas or moisture monitoring system. Up to three RATA SUMMARY
DATA records (along with their associated RATA RUN DATA records) are reported for a RATA
of a flow monitoring system, depending upon whether the test was performed at one, two, or
three operating levels. There should be a minimum of nine RATA RUN DATA records reported
for each operating level, unless the RATA was aborted.
In addition to the records listed above, the following records must be reported in certain
circumstances:
● Report FLOW RATA RUN DATA records and RATA TRAVERSE DATA records for RATAs
of flow monitoring systems in which:
-- Method 2F or 2G is used; or
-- Method 2 is used, and a calculated wall effects adjustment factor is determined by
direct measurement using Method 2H.
For Method 2F and 2G RATAs, report a FLOW RATA RUN DATA record for each run
used to calculate relative accuracy (i.e., Run Status Code is equal to "RUNUSED" in
the RATA RUN DATA record).
For Method 2 RATAs using Method 2H to derive a measured wall effects adjustment
factor, report a FLOW RATA RUN DATA record for the run (or runs) used to calculate
the wall effects adjustment factor.
With each FLOW RATA RUN DATA record, report a RATA TRAVERSE DATA record
for each Method 1 traverse point in the run. There should be a minimum of twelve
RATA TRAVERSE DATA records reported for each run. However, a minimum of
sixteen records is required for circular stacks using a calculated wall effects
adjustment factor.
Environmental Protection Agency
Quality Assurance and Certification Reporting Instructions -- Page 47

2.4 Relative Accuracy Test Audit (RATA)
● Report a TEST QUALIFICATION DATA record to claim an exception from the usual testing
requirements. Additional details are provided in the TEST QUALIFICATION DATA record.
There are three types of claims for which this record is appropriate:
1. Single-load Flow RATA claim. For locations that have an installed stack flow
monitor and operate primarily at a single operating level (in accordance with Part 75,
Appendix B Section 2.3.1.3(c)(3)), include this claim with each flow RATA to
indicate the supporting load operation percentages.
2. Exception from Normal Load requirement for pollutant system. For unusual
situations in which a single-level RATA could not be performed at the normal
operating level, include this claim if the RATA was performed at a different operating
level. You must receive specific EPA approval to qualify for this exception.
3. Exception from Normal Load requirement for flow system. For unusual
situations in which a multi-level flow RATA could not be performed when the unit
was operating at normal load ranges, include this claim if the load ranges of the
operating levels tested deviated from the values reported in the MONITORING LOAD
DATA record for the unit or stack. You must receive specific EPA approval to qualify
for this exception.
Specific Considerations
General Requirements
● RATAs are performed and reported only on a system basis. For example, the RATA for
a NOx-diluent monitoring system must be performed on a lb/mmBtu basis, and not on an
individual component basis.
● Gas monitor RATAs are always single-load tests, performed at the designated normal
load. If two normal loads are defined in the monitoring plan, the test may be done at
either load level.
● Flow RATAs are generally required to be performed at three operating levels (low, mid,
and high) for initial certification and recertification. For ongoing QA tests, the RATAs
are generally done at the two most frequently-used operating levels, although a three-load
test is required at least once every five years (20 calendar quarters), and whenever the
flow monitor polynomial constants or K-factors are changed. Note the following
exceptions:
-- For flow monitors installed on peaking units and bypass stacks, only single-load flow
RATAs are required.
-- Some units have approved petitions to perform tests at fewer than the standard
number of load levels. If the exemption from the standard requirement is ongoing,
this information should be reported in the MONITOR QUALIFICATION DATA record in
the monitoring plan. If the exemption is test-specific, such as a single-load claim
based on operating for ≥ 85.0 percent of the time at a single load since the previous
Quality Assurance and Certification Reporting Instructions -- Page 48
Environmental Protection Agency
2.4 Relative Accuracy Test Audit (RATA)
June 17, 2009
annual flow RATA, this information should be reported in a TEST QUALIFICATION
DATA record.
Aborted or Discontinued RATAs
● Report the results of all completed and aborted RATAs which affect data validation.
However, for ozone season-only reporters, an aborted or failed pre-ozone season RATA
need not be reported if a subsequent RATA is passed prior to the start of the current
ozone season.
● An aborted RATA is treated as a failed test if the RATA is discontinued due to a monitor
system failure, and the results must be reported. It is not necessary to report, or to treat as
a failed test, a RATA which is discontinued because of a failure which is unrelated to
instrument performance, such as a power outage, unit outage, unit stability problems, or
reference method failure.
● Also do not report the results of trial RATA runs that are part of the process of
optimizing the performance of a monitor, when the injections meet the acceptance criteria
in §75.20(b)(3)(vii)(E). For trial runs that do not affect data validation, document the
results as part of the official test log and maintain records on-site (or at an alternative
location known to the regulatory agency, if on-site storage is not feasible).
RATA Deadlines
● For units or stacks reporting data on a year-round basis, for routine quality assurance, a
RATA of each primary or redundant backup CEMS is required either semiannually (i.e.,
once every two QA operating quarters) or annually (i.e., once every four QA operating
quarters), depending on the relative accuracy percentage obtained in the previous RATA.
However, a RATA is required once every eight calendar quarters, regardless of how
many QA operating quarters have elapsed since the last test.
● For a non-redundant backup monitoring system, a RATA is required only once every
eight quarters, unless it is used at a particular unit or stack location for more than 720
hours in a calendar year (see §75.20(d)). To claim this exemption, report the appropriate
TEST EXTENSION EXEMPTION DATA record.
● Part 75 also allows extensions of SO2 RATA deadlines based on the type of fuel
combusted during the quarter and provides conditional RATA exemptions in certain
instances. Use the TEST EXTENSION EXEMPTION DATA records to report these claims.
(See the TEST EXTENSION EXEMPTION DATA instructions for details.)
● If a required RATA is not completed by the end of the quarter in which it is due, a 720
unit/stack operating hour grace period is allowed to perform the test. A TEST EXTENSION
EXEMPTION DATA record is not needed to claim the exemption.
● For units or stacks reporting data only in the ozone season, a successful RATA of each
primary and redundant backup CEMS is required prior to each ozone season. The RATA
is to be completed no later than April 30 each year in either the first or second calendar
Environmental Protection Agency
Quality Assurance and Certification Reporting Instructions -- Page 49
June 17, 2009
2.4 Relative Accuracy Test Audit (RATA)
quarter, but no later than April 30 (see §75.74(c)(2)(ii)). Note that the QA operating
quarter method of determining RATA deadlines and data validation status does not apply
to these units or stacks.
● The RATA grace period provisions in Section 2.3.3 of Appendix B also do not apply to
units or stacks reporting data only in the ozone season. However, a 720 unit (or stack)
operating hour conditional data validation period may be used to complete a RATA after
the April 30 deadline (see §75.74(c)(2)(ii)(F), (c)(3)(xi) and (c)(3)(xii)). You must
submit a QA CERTIFICATION EVENT DATA record to document the required probationary
calibration error and conditional data validation period.

Number of Load Levels
Element Name: NumberOfLoadLevels
Report the number of operating level tests which are required for a successful RATA. For
RATAs of gas and moisture systems, report "1." For flow RATAs, report "1," "2," or "3," as
appropriate.
Relative Accuracy
Element Name: RelativeAccuracy
Report the result of the relative accuracy test, as required and defined for the appropriate test
method and in Part 75, Appendix A. For multi-level flow RATAs, report the highest relative
accuracy at all tested operating levels. Leave this field blank for a RATA that is aborted prior to

For year-round reporters, report the frequency code from Table 10 below that identifies when a
RATA performed for initial certification, recertification, or routine QA expires and the next test
is due. For primary and redundant backup CEMS, the test frequency is based on the relative
accuracy percentage obtained, or, if necessary, on the alternative performance specification. If
the test qualifies for a reduced (i.e., annual) RATA frequency as provided in Part 75, Appendix
B, Section 2.3.1.2, report 4QTRS. If the RATA passes but does not qualify for annual
frequency, then the standard (semiannual) test frequency applies; in that case, report 2QTRS. If
a single load flow RATA is conducted as the required semi-annual test, report ALTSL. For nonEnvironmental Protection Agency

For the RATA of a moisture, CO2 or O2 monitoring system, the BAF will always be 1.000.
For a single-level RATA, report the BAF calculated at the tested operating level. For a multilevel flow RATA, report 1.000 only if the bias test is passed (i.e., the BAF was calculated as
1.000) at all normal operating levels. (A unit or stack may have one or two operating levels
designated as normal in the MONITORING LOAD DATA record.) If the bias test failed at any
normal operating level, report the higher of the BAFs that were calculated at the two most
frequently used operating levels, as designated in the MONITORING LOAD DATA record. (See
Section 6.5.2.1(d) and Section 7.6.5(c) of Appendix A to Part 75.)

RATA RUN DATA Elements
Instructions for completing each element of the RATA RUN DATA record are provided below.
Run Number
Element Name: RunNumber
Assign and report a run number to each measurement, beginning with the number "1" for each
operating level. Because all runs must be reported whether or not they are used to calculate the
relative accuracy test, run numbers must be consecutive and in chronological order. Do not skip
a run number.
Begin Date

Report the hour, on the run begin date, in which the run began. Run times must not overlap.
Begin Minute
Element Name: BeginMinute
Report the minute, during the run begin hour, in which the run began. Run times must not
overlap.
End Date
Element Name: EndDate

CEM Value
Element Name: CEMValue
Report the measured value from the monitoring system being tested in the appropriate units for
the run. Report these values to the same precision as is required for hourly data (i.e., to the
nearest 0.1 ppm; 0.1% CO2, O2, or H2O; 0.001 lb/mmBtu; or 1000 scfh, as applicable). For flow
monitors installed on rectangular stacks or ducts, if using Conditional Test Method CTM-041 to
apply a correction for wall effects, the reference method and flow monitor run values reported in
RATA RUN DATA will be wall effects-adjusted flow rates.
RATA Reference Value
Element Name: RATAReferenceValue
Report the measured value from the reference method against which the monitoring system is
being compared. This value should reflect adjustment, as necessary, for moisture and/or
calibration bias. Also report these values to the same precision as required for hourly data. For
flow monitors installed on rectangular stacks or ducts, if using Conditional Test Method CTM041 to apply a correction for wall effects, the reference method values reported in RATA RUN
DATA will be the wall effects-adjusted flow rates.

Gross Unit Load or Average Velocity at Operating Level
Element Name: GrossUnitLoad
Report the load level in megawatts or steam load during each RATA run for load-based units.
The units for this value should be consistent with the units used to define load levels in the
MONITORING LOAD DATA record of the monitoring plan.
For units that do not produce electrical or steam load (e.g., cement kilns, refinery process heaters,
etc.), report the average stack gas velocity at the operating level being tested. To determine the
appropriate average velocity, first divide the range of operation (which is defined in the
MONITORING LOAD DATA record in terms of stack gas velocity) into low, mid, and high
operating levels, as described in Section 6.5.2.1(b) of Appendix A. Then, report the velocity at
the midpoint of the tested level for each of the RATA runs (e.g., if the RATA is done at the
"high" operating level and the high level extends from 40 to 60 ft/sec, report 50 ft/sec as the
average velocity for each RATA run).
Run Status Code
Element Name: RunStatusCode
Report whether the run data were used to determine relative accuracy using one of the codes as
shown in Table 14.

in Method 3 to calculate Md.
Wet Molecular Weight
Element Name: WetMolecularWeight
Report Ms molecular weight of the stack gas for the test run, on a wet basis. Use Equation 2-6 in
Method 2 to calculate Ms.
Average Velocity without Wall Effects
Element Name: AvgVelocityWithoutWallEffects

The calculated average run velocity is the arithmetic average of the calculated point velocities at
the Method 1 traverse points (i.e., the average of all of the velocity values reported for the
Calculated Velocity data element in the RATA TRAVERSE DATA record for this test run).
Average Velocity with Wall Effects
Element Name: AverageVelocityWithWallEffects
For a circular stack using reference method codes 2FH, 2GH, or M2H, report the average run
velocity, considering wall effects if a WAF is derived using the data from this test run. Calculate
this value using the appropriate point velocity values from the RATA TRAVERSE DATA record's

Report this value even if you decide to apply a default WAF to all the runs of this RATA.
Leave this field blank for reference methods 2F, 2FJ, 2G, and 2GJ or if no WAF was calculated
from the data for this run.
Calculated Wall Effects Adjustment Factor (WAF)
Element Name: CalculatedWAF
For circular stacks using reference method codes 2FH, 2GH, or M2H, report the WAF if a WAF
is calculated using the data from this test run. Derive this value by dividing the adjusted velocity
value of the Average Velocity With Wall Effects by the unadjusted velocity value of the Avg

value even if you decided to apply a default WAF to all the runs of this RATA.
Leave this field blank for reference methods 2F, 2FJ, 2G, and 2GJ or if no WAF was calculated
from the data for this run.
Average Stack Flow Rate
Element Name: AverageStackFlowRate
Report the average stack gas flow rate for the test run, in scfh (wet basis). If wall effects are not
considered, calculate the average flow rate according to the applicable equation in Method 2, 2F,
or 2G, using the unadjusted average run velocity from the Avg Velocity Without Wall Effects
data element of this record in the calculations. If the stack is circular and wall effects
adjustments are applied, however, first obtain the wall effects-adjusted average velocity by
multiplying the calculated WAF or the default WAF (as appropriate) by the unadjusted average
velocity in accordance with Equation 2H-21 of Method 2H. Then, following the provisions of
Section 12.7 in Method 2H, use the final wall effects-adjusted velocity, obtained from Equation
2H-21, in the applicable equation from Method 2, 2F, or 2G to calculate the wall effects-adjusted
stack gas flow rate. Report this adjusted flow rate as the Average Stack Flow Rate data element.
The flow rate value reported for this data element must equal the flow rate reported as the RATA
Reference Value for this run in the RATA RUN DATA record.
For a rectangular stack or duct, if Conditional Test Method CTM-041 is used to determine a
WAF, calculate the average stack gas flow rate (in scfh), adjusted for wall effects, using the
following equation:

TEST QUALIFICATION DATA XML Elements
Description of Data
Report a TEST QUALIFICATION DATA record as part of a RATA test to claim an exception from the
usual RATA testing requirements. There are three types of claims for which this record is
appropriate:
1. For a location that has an installed stack flow monitor and is not exempt from performing
multi-load flow RATAs, the required annual flow RATA may be performed at a single
load (i.e., the designated normal load) if certain conditions are met. If the unit or stack
has operated primarily at a single load for ≥ 85.0 percent of the time since the last annual
flow RATA, and if fewer than 20 calendar quarters have elapsed since the last 3-load
flow RATA, a single load RATA claim may be submitted. Include this claim along with
the results of the single-load flow RATA, to document that the 85.0 percent criterion was
met (see Part 75, Appendix B, Section 2.3.1.3(c)(3)). Note that this single-load flow
RATA claim is not available to sources that report emissions data on an ozone seasononly basis.
2. For unusual situations in which a single-level RATA cannot be performed at the normal
operating load level (e.g., due to mechanical problems with the unit, include this claim if
the RATA is performed at a different operating level. You must receive permission from
EPA to claim this exception.
3. For unusual situations in which a multi-level flow RATA cannot be performed at one or
more of the required load levels (e.g., if the unit cannot attain the high-load level, due to
mechanical problems), include this claim record to indicate that tested load levels are not
consistent with the operating range defined in the MONITORING LOAD DATA record. You
must receive permission from EPA to claim this exception. If you obtain permission to
claim the exception, divide the available operating range into low, mid and high segments
according to Part 75, Appendix A, Section 6.5.2.1, and express the operating level for
each RATA (L, M, or H) in terms of the available range.

2.5 Flow-to-Load Reference
Description of Data
For each primary and each redundant backup flow monitoring system, an evaluation of the flowto-load ratio or the gross heat rate (GHR) is required in each QA operating quarter (as defined in
40 CFR 72.2). Do not analyze data recorded by a redundant backup flow monitors unless
emissions data are reported from the system during the quarter. In order to perform the flow-toload ratio or GHR evaluation, a reference value of the flow-to-load ratio (Rref) or the gross heat
rate (GHRref) must be derived from data collected during the most recent passing normal-load
RATA for the flow monitor. This information is reported in a FLOW-TO-LOAD REFERENCE DATA
record. The FLOW-TO-LOAD REFERENCE DATA record must be submitted as a "child" of a TEST
SUMMARY DATA record.
Specific Considerations
● When two levels are designated as normal in the MONITORING LOAD DATA record for the
location, report Flow-to-Load Reference Data separately for each level (i.e., in two TEST
SUMMARY DATA and FLOW-TO-LOAD REFERENCE DATA records).
● For a flow monitor on a common stack, Rref or GHRref is derived from the stack flow rate
and the combined unit loads for the units serving the stack. Report one TEST SUMMARY
DATA and FLOW-TO-LOAD REFERENCE DATA record for the common stack under the
Monitoring System ID of the flow monitor at the stack. For example, if CS1 is a
common stack serving Units 1 and 2, report these records under the flow monitoring
system ID associated with common stack CS1.
● For flow monitors in a multiple stack (MS) configuration, Rref or GHRref may be
calculated for each monitor separately or on a combined basis for the unit, as follows:
-- Derive a single Rref or GHRref from the sum of the flow rates in the individual stacks
or ducts and the unit load, and report the reference value multiple times (i.e., under
the Monitoring System ID of the flow monitor at each stack or duct); or
-- Calculate separate reference ratios for each stack, using the average reference method
flow rates and unit load during the RATA for the individual flow monitors. If this
approach is chosen, report "1" in the Calc Separate Reference Indicator in the FLOWTO-LOAD REFERENCE DATA record.
● Units that do not produce electrical or steam load (e.g., cement kilns) are exempted from
the requirement to perform flow-to-load testing.
● Report either the reference flow-to-load ratio or the reference GHR, but not both,
depending upon which approach is used in the quarterly flow-to-load check. In the
unusual circumstance where the flow-to-load check is performed using the flow-to-load
ratio in one quarter and the GHR in another quarter and both are based on the same
reference RATA, report two separate flow-to-load-reference tests (TEST SUMMARY DATA
PLUS FLOW-TO-LOAD REFERENCE DATA RECORD), one containing the reference GHR and
one containing the reference flow-to-load ratio.

runs (e.g., for two 9-run RATAs performed on stacks MS1 and MS2, add the load values for all
18 RATA runs and divide the result by 18).
Average Reference Method Flow
Element Name: AverageReferenceMethodFlow
Report the arithmetic mean of the stack flow rates in scfh (Qref) measured by EPA Reference
Method 2 (or its allowable alternatives) at the reported operating level of the reference RATA.
For a multiple stack configuration, if performing the test on a combined basis, calculate the mean
reference method flow rate by summing the mean reference method flow rates at the reported
operating level measured during the reference RATAs for all of the multiple stacks.
Reference Flow/Load Ratio
Element Name: ReferenceFlowLoadRatio
If the flow-to-load methodology was used, calculate and report Rref by dividing the average
reference method flow rate (Qref) by the average gross unit load (Lavg) and multiplying the result
by 10-5. Round the ratio to two decimal places.
Leave this field blank if the gross heat rate methodology for the quarterly flow monitor
evaluations was used.
Average Hourly Heat Input Rate
Element Name: AverageHourlyHeatInputRate
If the gross heat rate methodology was used, use the appropriate equation from Appendix F to
Part 75 to calculate HIavg, the average hourly heat input during the reference RATA at the
reported operating level. In the Appendix F equation, use the average hourly CO2 concentration
recorded during the RATA test period and the average reference method flow rate. Report this
average hourly heat input rate, rounded to one decimal place.

Flow-to-Load Check XML Structure
Description of Data
For each primary and each redundant backup flow monitoring system, a flow-to-load ratio or the
gross heat rate quality assurance test is required for every QA operating quarter, as described in
Section 2.2.5 of Appendix B to Part 75. Report the results of this check in a TEST SUMMARY
DATA record with an associated FLOW-TO-LOAD CHECK DATA record.
Environmental Protection Agency
Quality Assurance and Certification Reporting Instructions -- Page 91
June 17, 2009
2.6 Flow-to-Load Check
When two load levels are designated as normal in the MONITORING LOAD DATA record, perform
the quarterly flow-to-load ratio or GHR evaluation at the higher load level if sufficient data are
available for the analysis. Otherwise, perform the evaluation at the lower load level. If the test
is performed at the higher load level, report a flow-to-load check only for that load level. If there
are insufficient data available at the higher load level (i.e., < 168 hours of quality-assured flow
rate data within ± ten percent of Lavg) and the test is done at the lower load level, report flow-toload checks for both load levels. Report the test result as "FEW168H" or "EXC168H" (as
appropriate) for the higher load level in the TEST SUMMARY DATA record to indicate whether the
insufficient data availability was due to a lack of operating hours at the high load level within ±
ten percent of Lavg or due to the allowable exclusion of data. For the lower normal load report a
test result of "PASSED" or "FAILED" (as appropriate) in the TEST SUMMARY DATA record. If
there are insufficient data at both load levels, report a flow-to-load check for both load levels,
indicating a test result of "FEW168H" or "EXC168H" (as appropriate) for both load levels. (See
also Table 18, "Flow-to-Load Result Codes and Descriptions," on page 96.)
Note that for a multiple stack configuration, if you elect to perform the data analysis on a
combined basis, rather than for each individual stack, you will obtain only a single test result,
since the flow-to-load ratio or GHR analysis is done at the unit level, not at the stack level.
However, you must report this same test result multiple times (i.e., once under each flow
Monitoring System ID associated with each of the multiple stacks).
Specific Considerations
Applicability of Flow-to-Load Checks
● Do not report a flow-to-load check for a redundant backup flow monitor unless stack
flow data from the monitor are reported in the emissions file for that quarter.
● Units that do not produce electrical or steam load (e.g., cement kilns) are exempted from
the requirement to perform flow-to-load testing.
Reporting Requirements for Flow-to-Load Checks
● For units or stacks for which you report data on a year-round basis, report flow-to-load
checks for each QA operating quarter (as defined in 40 CFR 72.2). For NOx Budget
Program units or stacks which report data only in the ozone season, report flow-to-load
checks only for the second and third calendar quarters, if those quarters are QA operating
quarters (see §75.74(c)(3)(iii)).
● Do not report a flow-to-load check for non-QA operating quarters (< 168 operating
hours).
Monitors Applying Rectangular Duct WAFs
● For rectangular stacks or ducts with installed flow monitors, when applying a wall effects
adjustment factor (WAF) to the data from the flow monitor, the WAF is entered into the
programming of the flow monitor as a correction to the stack or duct cross-sectional area.
As soon as the wall effects correction is applied, the measured stack gas flow rates at a
Quality Assurance and Certification Reporting Instructions -- Page 92
Environmental Protection Agency
2.6 Flow-to-Load Check
June 17, 2009
given load level will decrease, possibly by five percent or more. This reduction in the
reported flow rates may adversely impact the quarterly flow-to-load (Q/L) ratio test, and
may even cause a test failure, if the data from the most recent normal load flow RATA
(i.e., the RATA on which the reference Q/L ratio is based) were not corrected for wall
effects. Note that this effect is only temporary, and will disappear when the next normal
load flow RATA is done and the appropriate WAF is applied to the reference method
data. However, in the interim period while the effect is still present, EPA recommends
the following:
-- Report the reference flow-to-load ratio information in FLOW-TO-LOAD REFERENCE
DATA in the usual manner. Do not attempt to make any adjustment to the reference
method flow rate data recorded during the previous normal load RATA.
-- Perform the quarterly flow-to-load ratio test in the usual manner and assess the
impact of the wall effects adjustment that was applied to the stack flow rates. If the
test is passed, report the results of the flow-to-load check in the usual manner.
-- If the test is failed, the quarterly flow rate data may be copied, exported outside the
DAHS environment, and the wall effects correction may be removed from each
hourly flow rate, by dividing it by the WAF. Then, rerun the flow-to-load analysis.
Report these results as the flow-to-load check and put a note in the Test Comment
indicating that the WAF was removed from the flow rate data before running the
flow-to-load ratio test. Keep the results of the data analysis on-site, in a format
suitable for inspection.
● In the quarterly emissions file, the wall effects-adjusted flow rates must be reported in the
MONITOR HOURLY VALUE DATA record, as measured by the flow monitor and as
recorded by the DAHS, whether or not the WAF is removed from the flow rate data to
perform the flow-to-load ratio test.

Online Zero Calibration Error
Element Name: OnlineZeroCalibrationError
Report the results of the calibration error (CE) test for the online zero-level injection, as required
by Part 75.
For SO2, NOx, and flow monitors, express the results either as a percentage of the span value
(i.e., CE), or (for low emitters of SO2 and NOx or for low-span differential pressure flow
monitors) as the absolute value of the difference between the reference value and the measured
value (i.e., R - A). If the calibration error meets the standard specification, report the CE even
though the test would also pass the alternative specification. Only when the result does not pass
the standard specification, but meets the alternative specification, should you report |R - A|. If
the test does not pass either specification, report the CE.
For low-span differential pressure-type flow monitors that are calibrated on an H2O basis and
that use the alternative specification: (1) report "0.0" in this field if the value of R - A is < 0.01
inches of water; or (2) report "0.1" in this field if the value of R - A is > 0.01, but < 0.10 inches
of water; or (3) if the value of R - A is > 0.10 inches of water, report the result to the nearest
0.1 in. H2O. For CO2 and O2 monitors, express the result as in terms of absolute percent CO2 or
O2, since the results are always determined as the absolute value of the difference between the
reference value and the measured value (i.e., |R - A|).

Element Name: UpscaleGasLevelCode
Indicate whether the upscale gas injections or reference signals are "HIGH" or "MID." Midlevel gas injections in lieu of the high-level injections may be performed and reported, provided
that the mid-level gas is more representative of the actual stack emissions.
Online Zero APS Indicator
Element Name: OnlineZeroAPSIndicator
Report whether the online zero-level test result was determined using a normal specification "0"
or the alternative performance specification "1" allowed under Part 75.
Appendix A to Part 75 specifies that the calibration error of an O2 or CO2 monitor is always
expressed in percent O2 or CO2, rather than as a percentage of span. This is considered to be the
"normal" calibration error specification; therefore, "0" should be reported in this field. The
alternate performance specification applies only to SO2 and NOx pollutant concentration
monitors that are considered low-emitters of those pollutants and to low-span differential
pressure flow monitors.

3.1 Appendix E Correlation Test
Description of Data
To establish a NOx/heat input rate correlation curve based on Appendix E to Part 75, you must
perform reference method testing at a minimum of four load levels. Report the overall test
information in a TEST SUMMARY DATA record and report the test results at each load level in the
APP E CORRELATION TEST SUMMARY DATA record. The number of records required corresponds
to the number of loads tested. For example, if the Appendix E test is performed at four unique
load levels, report four APP E CORRELATION TEST SUMMARY DATA records. Report the test data
from a minimum of three runs for each load level in the APP E CORRELATION TEST RUN DATA
record.
Report a companion APPENDIX E HEAT INPUT FROM OIL DATA record for any Appendix E test
used to establish a NOx emission rate curve for use during hours in which oil is combusted. An
APPENDIX E HEAT INPUT FROM OIL DATA record verifies the calculation of heat input during the
run. There should be one APPENDIX E HEAT INPUT FROM OIL DATA record for each run reported
in an APP E CORRELATION TEST RUN DATA record when any of the fuel combusted was oil.
Report a companion APPENDIX E HEAT INPUT FROM GAS DATA record for any Appendix E test
used to establish a NOx emission rate curve for use during hours in which gas is combusted. An
APPENDIX E HEAT INPUT FROM GAS DATA record verifies the calculation of heat input during the
run. There should be one APPENDIX E HEAT INPUT FROM GAS DATA record for each run reported
in an APP E CORRELATION TEST RUN DATA record when any of the fuel combusted was gas.
If you are establishing a correlation curve based on a consistent fuel mixture, report the
appropriate combination of APPENDIX E HEAT INPUT FROM OIL DATA record(s) and/or APPENDIX
E HEAT INPUT FROM GAS DATA record(s) for each run.
Specific Considerations
Aborted or Invalid Tests
● If a test is aborted or if certain test runs are discarded as invalid, keep a record of this in
the test log, but do not report partial tests or invalid runs in the APP E CORRELATION TEST
RUN DATA record. The only acceptable reasons for aborting a test or discarding test runs
are: (1) the reference test method was not used properly or malfunctioned; or (2) a
problem with the unit or process prevented the test from being done at the load level or
conditions specified in the regulation.

Description of Data
If the fuel flowmeter is calibrated with a flowing fluid, report fuel flowmeter accuracy test results
in a FUEL FLOWMETER ACCURACY DATA record (i.e., if the flowmeter is calibrated in a
laboratory or by an in-line calibration against a reference flowmeter, or both). (See Sections
2.1.5.1 and 2.1.5.2 of Appendix D to Part 75.) The FUEL FLOWMETER ACCURACY DATA record
must be submitted as a "child" of a TEST SUMMARY DATA record. If the flowmeter is an orifice,
nozzle, or venturi-type that meets the design criteria of AGA Report No. 3, report the results of
Environmental Protection Agency

3.2 Fuel Flowmeter Accuracy Test
the transmitter/transducer calibrations and primary element inspections using, respectively, the
TRANSMITTER TRANSDUCER DATA record and the TEST SUMMARY DATA record for
Miscellaneous Tests.
Specific Considerations
Multi-Flowmeter Systems
● Report separate Fuel Flowmeter Accuracy tests for each installed flowmeter component
for fuel flowmeter systems with multiple flowmeter components (e.g., a system with a
main supply meter and a return meter, or a system consisting of multiple flowmeters
supplying the same type of fuel to a unit or to a group of low mass emissions (LME)
units).
Frequency of Testing
●
Flowmeter accuracy tests are required once every four "fuel flowmeter QA operating
quarters," as defined in 40 CFR 72.2, with a maximum of 20 calendar quarters between
successive tests. However, the optional fuel flow-to-load ratio test in Section 2.1.7 of
Appendix D may be used to extend the interval between successive accuracy tests up to
20 calendar quarters, irrespective of the number of fuel flowmeter QA operating quarters
that have elapsed since the previous test.
●
Do not report accuracy test results if the meter is temporarily put into storage after being
recalibrated (i.e., if the fuel flowmeter component is not active and is therefore not part of
the monitoring plan). A fuel flowmeter QA operating quarter is counted against a
flowmeter only when the meter has been re-installed, not if it is in storage (refer to the
Part 75 Emissions Monitoring Policy Manual).

Description of Data
For orifice, nozzle, and venturi-type fuel flowmeters, that conform to AGA Report No.3, the
owner or operator may opt to certify the meters by calibrating the transmitters (or transducers)
using NIST-traceable equipment and performing a visual inspection of the primary element, in
lieu of calibrating the meters with a flowing fluid. If this option is chosen, use a TEST SUMMARY

3.3 Transmitter Transducer Test
DATA record and the TRANSMITTER TRANSDUCER DATA record, to report the results of the
transmitter or transducer accuracy tests, performed according to Section 2.1.6.1 of Appendix D
to Part 75.
Specific Considerations
Frequency of Testing
● Transmitter/transducer accuracy tests are required once every four "fuel flowmeter QA
operating quarters" (as defined in §72.2 of Part 75) with a maximum of 20 calendar
quarters between successive tests. However, the optional fuel flow-to-load ratio test in
Section 2.1.7 of Appendix D may be used to extend the interval between successive
accuracy tests up to 20 calendar quarters, irrespective of the number of fuel flowmeter
QA operating quarters that have elapsed since the previous test. Submit one
TRANSMITTER TRANSDUCER DATA record for each transmitter or transducer accuracy test
performed.
● For a combined cycle combustion turbine (CT) with a duct burner (DB), if the same fuel
is combusted in both the turbine and the duct burner, show the CT and DB fuel
flowmeters as separate components of the same monitoring system. In this case, both
flowmeters must be up-to-date on their required QA tests to maintain an "in-control" QA
status for the system. The interval between the required QA tests is determined in the
same way for both components. The number of hours that the fuel is combusted during
the quarter determines whether a "QA quarter" is counted against a particular flowmeter,
not the number of hours that the flowmeter is used.
Example: A combined cycle turbine with a duct burner combusts only natural gas. In the thirdquarter of 2007, natural gas is combusted for 250 hours in the unit. The duct burner operates
only for 50 hours. In this case, since natural gas was combusted in the unit for > 168 hours, a
fuel flowmeter QA operating quarter is counted against both the CT and DB flowmeters, even
though the DB flowmeter was used for only 50 hours.

3.4 Fuel Flow-to-Load Baseline
Description of Data
If you elect to use the optional fuel flow-to-load ratio test provisions of Section 2.1.7 of
Appendix D to Part 75 to extend the deadline for required fuel flowmeter accuracy tests, report a
TEST SUMMARY DATA record and its corresponding FUEL FLOW-TO-LOAD BASELINE DATA
record for each fuel flowmeter system that will be quality-assured using fuel flow-to-load ratio or
gross heat rate (GHR) methodology, upon completion of the baseline data collection. According
to the provisions of Section 2.1.7.1, the baseline fuel flow-to-load ratio or GHR must be
supported by at least 168 hours of baseline fuel flow-to-load ratio or gross heat rate (GHR) data.
Specific Considerations
Reporting Baseline Data
● For orifice, nozzle, and venturi fuel flowmeters relying on conformance with AGA
Report No. 3 for certification and QA, baseline data collection begins immediately after
completing the full quality assurance sequence (i.e., flowmeter transmitter/transducer
calibration test and primary element inspection (PEI)). The transmitter calibrations and
PEI must either be completed in the same calendar quarter or in the adjacent quarters.
● For flowmeters that do not require a PEI, if the calibration occurs on-site, baseline data
collection begins immediately after completing the accuracy test. If the calibration
occurs off-site, baseline data collection begins immediately after the flowmeter is
reinstalled.
● The baseline data must be generated within four calendar quarters.
● For common pipe configurations, a single baseline fuel flow-to-load ratio or GHR is
derived from the average common pipe fuel flow rate and the hourly loads for all units
that received fuel from the common pipe. Thus, report only one FUEL FLOW-TO-LOAD
BASELINE DATA record for the common pipe (see Part 75, Appendix D, Section
2.1.7.1(b)).
● For units that co-fire fuels as the principal mode of operation, use the GHR methodology
and derive the baseline data during co-fired hours (see Part 75, Appendix D, Section
2.1.7.1(e)). Report a TEST SUMMARY DATA record for each fuel flowmeter system that
supplies fuel to the unit during co-fired hours. In the associated FUEL FLOW-TO-LOAD
BASELINE DATA records for these systems, report the identical co-fired baseline
information.

For orifice, nozzle, and venturi fuel flowmeters required to perform a transmitter accuracy test as
periodic quality assurance (under Section 2.1.6 of Appendix D), report the test number of the
most recent transmitter accuracy test (according to Sections 2.1.6.1 through 2.1.6.5 of Appendix
D). For all other fuel flowmeters, report the test number of the most recent flowmeter system
accuracy test (according to Section 2.1.5.1 or 2.1.5.2 of Appendix D).

3.4.2 Fuel Flow-to-Load Baseline Data
Primary Element Inspection (PEI) Test Number
Element Name: PEITestNumber
For orifice, nozzle, or venturi fuel flowmeters required to perform a visual inspection of the
primary element as periodic quality assurance (under Section 2.1.6.6 of Appendix D), report the
test number of the most recent primary element inspection. For all other types of fuel
flowmeters, leave this field blank.
Average Fuel Flow Rate
Element Name: AverageFuelFlowRate
Report the hourly average fuel flow rate during unit operation measured by the fuel flowmeter
system during the baseline period (i.e., Qbase from Equation D-1b in Section 2.1.7.1 of Appendix
D). If you elect to use the gross heat rate (GHR) option and report the average hourly heat input
rate, leave this field as blank.
For a system with more than one fuel flowmeter, you must determine the net hourly fuel flow
rate for each hour in the baseline data collection period. The net fuel flow rate may represent the
difference between the values measured for the main supply and recirculating fuel lines, or may
represent the sum of fuel flow for two or more fuel flowmeters measuring the same type of fuel
to the unit. For a combined cycle turbine with auxiliary firing (e.g., a duct burner), if the duct
burner operates infrequently (i.e., < 25 percent of the unit operating hours, on average), you may
establish the baseline for the fuel flowmeter system using the hours when only the combustion
turbine is in operation. Add together all of the net hourly fuel flow rates and divide by the
number of hours in the baseline data collection period to obtain Qbase.
Average Load
Element Name: AverageLoad
Report the average unit load during the baseline period (i.e., Lavg from Equation D-1c in Section
2.1.7.1 of Appendix D). For a common pipe, add together all of the hourly operating loads for
all units that received fuel through the common pipe header during the baseline data collection
period. Divide the result by the number of hours in the baseline data collection period to obtain
Lavg. For a combined cycle turbine with auxiliary firing, if the duct burner operates infrequently
(< 25 percent of the unit operating hours, on average) and you may establish the baseline using
hours when only the turbine is in operation, use the corresponding hourly electrical outputs from
the turbine to determine Lavg.
Baseline Fuel Flow-to-Load Ratio
Element Name: BaselineFuelFlowToLoadRatio
Report the baseline fuel flow-to-load ratio calculated as Rbase from Equation D-1b in Section
2.1.7.1 of Appendix D. If you report the Baseline GHR, you may leave this field blank.

Quality Assurance and Certification Reporting Instructions -- Page 159
June 17, 2009
3.5 Fuel Flow-to-Load Test
fuel flowmeter accuracy and transmitter/transducer tests, you may extend the QA deadline by
one quarter by reporting one fuel flow-to-load test per fuel flowmeter system. Report the flowto-load test results in a TEST SUMMARY DATA record and the details of the flow-to-load analysis
in an associated FUEL FLOW-TO-LOAD TEST record.
Report this test every operating quarter, starting with either:
● The first operating quarter following the quarter in which all the required fuel flowmeter
accuracy tests, transmitter/transducer accuracy tests, and primary element inspections are
completed for flowmeters that are calibrated on-site; or
● The first operating quarter following the quarter that the flowmeter was reinstalled for
flowmeters that are calibrated off-site.
If baseline data collection is still in progress at the end of the quarter, report a test result of
"INPROG" in the TEST SUMMARY record and do not report a FUEL FLOW-TO-LOAD TEST record.
Specific Considerations
Submitting for a Combined-Cycle Combustion Turbine (CT)
● For a combined-cycle combustion turbine (CT) with a duct burner, if the fuel flowmeters
serving the CT and the duct burner are represented as components of a single fuel
flowmeter monitoring system, the fuel flow-to-load ratio test may be performed using
only the turbine fuel flow rate and load, provided that the duct burner is used, on average,
for < 25 percent of the unit operating hours.
● For units that co-fire fuels as the principal mode of operation, use the GHR methodology
and use only co-fired hours in the data analysis (see Part 75, Appendix D, Section
2.1.7.2(d)(2)). Report a TEST SUMMARY DATA record for each fuel flowmeter system
that supplies fuel to the unit during co-fired hours. In the associated FUEL FLOW-TOLOAD TEST records for these systems, report the identical information from the co-fired
data analysis.
Reporting Frequency
● Do not report this record for non-operating quarters (i.e., quarters with zero operating
hours).
● For ozone season only reporters, fuel flow-to-load ratio tests are required only during the
ozone season. Therefore, for such units or pipes, report a FUEL FLOW-TO-LOAD TEST
DATA record only for the second and third calendar quarters, if those quarters are
operating quarters (see §75.74(c)(3)(v)).

3.6 Unit Default Test (LME)
Description of Data
To establish a unit-specific, fuel-specific NOx emission rate for qualifying low mass emissions
(LME) units under the Acid Rain Program or Subpart H, perform Appendix E testing at each of the
required load levels, as described in §75.19 (c)(1)(iv)(A), (I) and (J). Report fuel-and-unit specific
NOx emission rate tests using a TEST SUMMARY DATA record, a UNIT DEFAULT TEST DATA record,
and UNIT DEFAULT TEST RUN DATA records for each run at each operating level of the test.
Indicate each test run used to calculate the highest three-run average NOx emission rate, by
reporting "0" for "no" or "1" for "yes" in the Run Used Flag data element of the appropriate UNIT
DEFAULT TEST RUN DATA records. Report only three records with this indicator; for all other
records leave this field blank.
Specific Considerations
Aborted or Invalid Tests
● If a test is aborted or if certain test runs are discarded as invalid, keep a record of this in the
test log, but do not report partial tests or invalid runs in the UNIT DEFAULT TEST RUN DATA
record. The only acceptable reasons for aborting a test or discarding test runs are: (1) the
reference test method was not used properly or malfunctioned; or (2) a problem with the
unit or process prevented the test from being done at the load level or conditions specified
in the regulation.

5.0 QA Certification Event Data
June 17, 2009
5.0 QA CERTIFICATION EVENT DATA
Figure 42
QA CERTIFICATION EVENT DATA XML Elements
Description of Data
Normal operation and maintenance of monitoring systems usually necessitates replacement or
repair of various components or changes to the type of equipment or software installed to
measure and report emissions. These changes may occur unexpectedly during normal operation
or according to a maintenance schedule. Diagnostic testing and in some instances certification or
recertification testing is required when such repairs, component replacements, or equipment
changes are made.
Submit one QA CERTIFICATION EVENT DATA record for each event requiring certification,
recertification or other non-routine testing of a monitoring system. This data record identifies
the nature of the event, the date and time it occurred, and the monitoring system and/or
component to which it is relevant. Also, for ozone season only reporters, submit a QA
CERTIFICATION EVENT DATA record when using conditional data validation in situations where
the required QA linearity or RATA was not completed by the required deadline (i.e., April 30 or
July 30, as applicable; see §75.74(c)(2)(ii)(F) and (c)(3)(ii)(E)).
Environmental Protection Agency
Quality Assurance and Certification Reporting Instructions -- Page 185
June 17, 2009
5.0 QA Certification Event Data
The QA CERTIFICATION EVENT DATA record also defines any time period(s) during which data
from a monitoring system are considered to be "conditionally valid" pending the outcome of the
required certification, recertification, quality assurance, or diagnostic tests. Data are considered
quality-assured when all of the required QA tests have been successfully completed. When
"conditional" data validation is used, it must be done in accordance with procedures in
§75.20(b)(3) prior to completing all of the required certification, recertification, or diagnostic
testing. Under §75.20(b)(3), the conditionally valid data status begins when a probationary
calibration error test is passed. If the required QA tests are then completed in a timely manner
with no failures, the conditionally valid data are considered to be quality-assured back to the
hour of completion of the probationary calibration error test.
Regarding recertifications, note that with one exception (i.e., changing of the polynomial
coefficient(s) or K-factor(s) of a flow monitor or moisture monitoring system) the definition of a
"recertification event" is limited to those non-routine changes to a monitoring system or process
which require either: (1) RATA(s); (2) fuel flowmeter accuracy testing; (3) a full QA sequence
of transmitter tests and primary element inspections (for orifice, nozzle and venturi-type fuel
flowmeters); or (4) regeneration of an Appendix E NOx correlation curve. Submittal of a formal
recertification application is required only for such recertification events.
Note that when a monitoring system is replaced, a new, unique system ID is assigned and the
new system must be tested for certification. When an analyzer is replaced in a previously
certified system and a new system ID is assigned, this is also considered to be a certification
event. If the old system ID is retained, it is considered to be a recertification event (refer to the
Part 75 Emissions Monitoring Policy Manual).
Report a QA CERTIFICATION EVENT DATA record as follows:
● When conducting initial certification testing of any system on a new (or newly-affected)
unit.
● Whenever recertification testing or diagnostic testing is required as a result of changes
made to a previously certified monitoring system (or as the result of changes in the
manner of operating the process). Refer to the Part 75 Emissions Monitoring Policy
Manual.
● When a monitoring system is replaced with a new system (having a new system ID) and
is tested for certification.
● When the conditional data validation procedures of §75.20(b)(3) are used following
repair, corrective maintenance or reprogramming of the monitor (see Sections 2.2.3(b)(3)
and 2.3.2(b)(3) of Appendix B).
● For ozone season-only reporters, when using conditional data validation because the
required QA linearity check or RATA was not completed by the required deadline.
● If a routine quality assurance test is done for the dual purposes of routine QA and
recertification (see Part 75, Appendix B, Section 2.4).
Quality Assurance and Certification Reporting Instructions -- Page 186
Environmental Protection Agency
5.0 QA Certification Event Data
June 17, 2009
● For the required linearity checks of non-redundant backup monitors and temporary "likekind replacement" analyzers, when these monitors are brought into service (see
§75.20(d)(2)(iii)).
● When the polynomial coefficients or K-factor(s) of a flow monitor or moisture
monitoring system are changed, triggering an unscheduled RATA requirement.
● When a change from a non-CEMS-based monitoring methodology to a CEMS
methodology occurs (e.g., changing from Appendix E to a CEMS for NOx), and the
conditional data validation procedures of §75.20(b)(3) are applied during the CEMS
certification process.
● When there has been a change in the coal rank of the primary fuel. Retesting is also
required within 720 unit operating hours of the change.
● When recertification is required as a result of events referenced in §75.4.
Do not report a QA CERTIFICATION EVENT DATA record:
● For the routine periodic quality assurance tests required under Appendices B, D, and E of
Part 75, except when conditional data validation is used.
● If the only diagnostic test required for a particular event is a calibration error test.
● For any event listed in the recertification and diagnostic testing tables in the Part 75
Emissions Monitoring Policy Manual that does not require QA CERTIFICATION EVENT
DATA record to be submitted.
● When a change from a CEMS-based monitoring methodology to a non-CEMS
methodology occurs (e.g., switching from an SO2 CEMS to Appendix D, or changing
from a NOx CEMS to Appendix E ). In such cases, simply use the MONITORING METHOD
DATA records to indicate changes in monitoring methodology. However, if the opposite
occurs, (i.e., changing from a non-CEMS-based methodology to CEMS), report a QA
CERTIFICATION EVENT DATA record if the conditional data validation procedures of
§75.20(b)(3) are applied during the CEMS certification process.
Specific Considerations
The following typical certification, recertification, and maintenance events would be reported in
this record.
● Replacement of an entire continuous emission monitoring system;
● Change-outs of analytical or other monitoring system components;
● DAHS vendor changes or software version upgrades;
Environmental Protection Agency
Quality Assurance and Certification Reporting Instructions -- Page 187
June 17, 2009
5.0 QA Certification Event Data
● Changing of the polynomial coefficient(s) or K-factor(s) of a flow monitor or moisture
monitoring system;
● Modification to the flue gas handling system or unit operation that significantly changes
the flow or concentration profile;
● Probe location change, for gas monitoring systems;
● Flow monitor location change; and
● Other system modifications that require one or more tests, as determined in accordance
with the EPA policy (refer to the Part 75 Emissions Monitoring Policy Manual) or
through consultation with EPA Regional Office and Headquarters staff.

ID number. If only component-level tests are required (e.g., linearity checks), leave this field
blank.
Component ID
Element Name: ComponentID
If the event requires any component-level tests report the component ID subject to the

tests on more than one component, be sure to report a QA Certification Event record for each
applicable component.) If the event only requires system level tests (e.g., a RATA), leave this
field blank. Examples of Event Codes that are system specific but not component-specific
include 5, 10, and 130.

QA Cert Event Date
Element Name: QACertEventDate
Report the date of the event. If the monitoring system is deemed to be out-of-control (unable to
provide quality-assured data) as a result of changes made to the system, report the date of that
change. If there is no out-of-control period associated with a particular event, report the date and
hour of the beginning of the event. This date and hour must precede the date and hour of
commencement of the required diagnostic or recertification tests.
Consider the following scenarios:
● For certifications and recertifications triggered by the replacement of a monitoring
system or an analyzer, report the date and hour on which the replacement monitoring
system or analyzer is first installed.
● For the initial certification of monitoring systems on new (or newly-affected) units (QA
Cert Event Codes 125 and 305), report a date and hour that predates, but is close in time
to, the commencement date and hour of the certification testing. If you use the
conditional data validation procedures of §75.20(b)(3), the beginning date and hour of the
certification event must precede the date and hour of the probationary calibration error
test.
● For installation of add-on controls or the construction of a new stack or flue (QA Cert
Event Codes 20 through 26, and 40), report the date on which emissions first exited to the
atmosphere through the new operating controls, stack, or flue. (Refer to the Part 75
Emissions Monitoring Policy Manual.)
● When a DAHS is replaced or the DAHS software version is upgraded, and the old and
new platforms or software versions are run in parallel (so that there may be a smooth
transition from the old to the new, with no monitoring system out-of-control periods
associated with the DAHS replacement or upgrade), report the date and hour at which the
new DAHS platform or software version first begins to be run in parallel with the old
platform or version.

Conditional Begin Date
Element Name: ConditionalBeginDate
If applicable, report the date on which conditional data validation began. For gas CEMs or flow
monitoring systems only, whenever using the conditional data validation procedures of
§75.20(b)(3), report the date that a probationary calibration error test was successfully completed
according to the provisions of §75.20(b)(3). Data are conditionally valid from that date until all
required tests are passed, provided that all tests are passed in succession, within the allotted
window of time, with no failures.
Note that in most instances, the allotted time for completing the required tests will be as
specified in §75.20(b)(3)(iv). However, for the initial certification of the CEMS installed on a
new (or a newly affected) unit, the timelines in §75.20(b)(3)(iv) are superseded by the
certification window provided in the applicable regulation. Leave these fields blank if the
conditional data validation procedures in §75.20(b)(3) are not used. Also, leave this field blank
for excepted monitoring systems under Appendices D or E to Part 75. When a new stack is
constructed or when add-on SO2 or NOx emission controls are installed, a longer window of time
is allotted in §75.4(e) for the required certification, recertification and/or diagnostic testing (refer
to the Part 75 Emissions Monitoring Policy Manual).
Also, if the Event Code indicates initial certification, analyzer replacement, or complete
replacement of a monitoring system (Event Codes 40, 50, 51, 100, 101, 120, 125, 151, 250, 255,
300 or 305) and conditional data validation is used, a BAF of 1.000 should be applied to the
hourly data (where applicable) from the beginning of the conditional data validation period to the
completion hour of the certification or recertification RATA. For any other events that require a
RATA, apply the BAF from their previous RATA during the conditional data period, unless that
RATA failed or was aborted, in which case use 1.000.

6.0 Test Extension Exemption Data
June 17, 2009
6.0 TEST EXTENSION EXEMPTION DATA
Figure 43
TEST EXTENSION EXEMPTION DATA XML Elements
Description of Data
To claim a quarter-specific test extension or exemption from the standard QA test schedule or
requirements under any program, report a TEST EXTENSION EXEMPTION DATA record. Each
record identifies the monitoring system and/or component to which the extension or exemption
applies the year and quarter of the extension or exemption, and a code indicating the specific
type of extension or exemption being claimed.
Use this record to claim the following types of extensions and exemptions:
For CEM systems:
● Only very low-sulfur fuel was combusted this quarter (extends SO2 RATA deadline).
● Analyzer Range was not used this quarter and fewer than four calendar quarters have
elapsed since the last linearity check on this range (exempts from linearity on that range).
Environmental Protection Agency
Quality Assurance and Certification Reporting Instructions -- Page 197
June 17, 2009
6.0 Test Extension Exemption Data
● Year-to-date usage of this "regular" non-redundant backup monitoring system is no more
than 720 hours and fewer than eight full quarters have elapsed since the last RATA (see
§75.20(d)).
● Emissions exhausted during quarter for less than 168 operating hours through bypass
stack on which a primary-bypass (PB) monitoring system is located (exempts monitor
from linearity and RATA).
For non-CEM systems:
● This calendar quarter was not a "fuel flowmeter QA operating quarter" (as defined in
40 CFR 72.2) for an ozone season-only reporter during quarters one, two, and four
(extends Fuel Flow Accuracy test schedule).
● Duct burner on combined-cycle turbine operated less than 168 operating hours during
quarter (extends accuracy test deadline for fuel flowmeter feeding the duct burner by one
quarter).
Do NOT use this record to claim the following types of extensions and exemptions, because
these extensions and exemptions are being determined through other reporting mechanisms:
● This calendar quarter was not a QA operating quarter (i.e., location operated less than
168 operating hours). (This is determined from hourly emissions data.)
● This calendar quarter was not a fuel flowmeter QA operating quarter (except as noted
above). (This is determined from hourly emissions data.)
● A claim for a 168-hour or 720-hour grace period extension. (This is determined from
hourly emissions data.)
● Linearity test exemption when span value for SO2 or NOx is less than 30 ppm. (This is
determined from the span record in the monitoring plan.)
● Extension of fuel flow accuracy testing through fuel flow-to-load testing. (This is
reported in a fuel flow-to-load test.)
● Special RATA claims (i.e., single-load flow claim, non-normal operating level claim,
operating range exception). (This is reported with the RATA in a Test Qualification
record.)
