Monitoring Plan
1.0 Introduction: The Monitoring Plan
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);
3) The Mercury and Toxics Standards (MATS) Rule; and
4) 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 Monitoring Plan 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 monitoring plan 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.

1.0 Introduction: The Monitoring Plan
About Monitoring Plan Data
The Monitoring Plan describes how a monitoring configuration monitors its emissions.
Monitoring plan data define relationships between stacks, pipes, and units, specify locations at a
facility from which emissions are monitored, and identify systems of monitoring equipment by
detailing the individual system components. Monitoring plan data also provide operational
characteristics and qualifications for certain special types of monitoring (e.g., Low Mass
Emissions monitoring).

3.0 Stack Pipe Data
Types of Stacks and Pipes
When assigning IDs to stacks or pipes, consider the following types of stacks and pipes and the
associated ID prefix:
• Common Stacks; If a stack serves more than one unit and emissions are monitored at
that stack, it must be defined as a "common stack" for reporting purposes. Assign a
common stack ID beginning with the prefix "CS" followed by one to four alphanumeric
characters.
• Common Pipes: If a fuel pipe serves more than one unit and fuel flow is monitored at
that common pipe header, it must be defined as a "common pipe" for reporting purposes.
Assign a pipe ID beginning with the prefix "CP" followed by one to four additional
alphanumeric characters. If more than one fuel type is associated with the same group of
units, it is not necessary to report a common pipe for each fuel type: rather, define one
"common pipe" and define separate fuel flow monitoring systems for each fuel type at the
pipe.
• Multiple Ducts or Stacks: A multiple stack defines two or more ducts or stacks in
which C'F.MS are located for a single unit. (It also defines any additional monitoring
loc atiou(s) for a single unit that is also monitored at a common stack or common pipe.) If
a unit has a ( "EMS located in more than one duct or stack from the unit, assign a multiple
stack ID to each monitoring location. Assign a stack ID beginning with the prefix "MS"
followed by one to four alphanumeric characters.
• Multiple Pipes: For a combined cycle (CC) peaking unit with a combustion turbine and
duct burner for which: (1) Appendices D and E are used; and (2) fuel flow is measured
separately for the turbine and duct burner, define multiple pipes, i.e., one for each fuel
flowmeter location. Assign a pipe ID beginning with the prefix "MP" followed by one to
four alphanumeric characters. Consult with the EPA Clean Air Markets Division or state
agency prior to initial monitoring plan submission if a facility has this configuration.

Description of Data
The Unit Control Data record is used to identify emissions controls that are utilized or
planned for the specified unit. Submit a Unit Control Data record for each type of NOx, SO2,
or particulate control equipment in place or planned for each unit defined in the monitoring plan.
If emission controls that are specific to Hg, HC1 or HF removal are also in place or planned for a
unit, EPA recommends that you submit additional UNIT CONTROL DATA records to represent
these controls. These data include information describing the parameter emitted and the
corresponding control type. For controls with co-benefits (e.g., flue gas desulfurization systems
(FGD)), just list the control once using the parameter code that corresponds to the primary
pollutant controlled.
Do not report Unit Control Data for any parameter (NOX, S02, HG, HC1, HF, or PART) for
which the unit is uncontrolled. Similarly, do not report unit control data for a parameter if
emissions of that parameter are controlled only by limiting production or by switching fuels.

Description of Data
The Monitoring Location Attribute Data record provides a description of the physical
characteristics of a specified monitoring location. Submit a Monitoring Location Attribute
Data record for each multiple or common stack defined in a monitoring plan. Also report a
Monitoring Location Attribute Data record for each unit in the monitoring plan if
emissions are monitored or determined there. Do not report this record for pipes.
For multiple stack (MS) configurations, if the monitors are located on the stacks, report the
height, elevation and inside cross-sectional area (CSA) information for each stack (i.e., stack exit
CSA and, if applicable, the CSA at the flow monitor location). If the monitors are located at
breechings or ducts rather than on the stack, in the Monitoring Location Attribute record for
each multiple stack report the stack exit height, base elevation and inside CSA information for
the exhaust stack, and report the CSA at the stack exit and, if applicable, the inside CSA at the
flow monitor location in the ductwork.
For units that are part of a common pipe (CP) or multiple (MP) configuration and use Appendix
D estimation procedures for heat input, CO2, or SO2, report (using the appropriate Unit ID or
Stack ID) the stack height, elevation and inside cross-sectional area of the stack through which
emissions are discharged to the atmosphere. This can be a single unit stack or a stack serving
more than one unit. If the unit emits through more than one stack, report information for the
stack typically associated with higher emissions for the unit.

6.0 Monitoring Method Data
6.0 Monitoring Method Data
Figure 12
Monitoring Method Data XML Elements
Description of Data
The Monitoring Method Data record describes the emissions monitoring methodologies used
at each monitoring location identified in the monitoring plan. A separate MONITORING METHOD
Data record must be included for each parameter (NOX, S02, C02, etc.) monitored or
calculated at each identified monitoring location. For EGUs subject to the MATS rule, report the
Monitoring Method Data record only if compliance with an applicable Hg, HC1, HF, or SO2
standard is demonstrated by continuously monitoring the pollutant emission rate. If MATS
compliance for acid gases or HAP metals is determined by any other method (e.g., periodic stack
testing, parameter monitoring, etc.), report the optional supplemental mats compliance data
record instead (see section 6.1, below). Note that when heat input is not monitored at the unit
level, a Monitoring Method Data record for heat input must be included for both the
monitoring location and at the unit level.
For example, if all emissions are monitored at a common stack for Units 1 and 2, report one set
of monitor method records for the common stack location, which includes a single record for
each parameter monitored, and (if heat input monitoring is required) two additional records (i.e.,
one each for Units 1 and 2) indicating the method by which heat input is determined at the unit
level.
Report only one active method for each parameter monitored at the location. For locations with
an unmonitored bypass stack, use the Bypass Approach Code field in the applicable method
record(s) to report whether or not a fuel-specific default value will be used for bypass hours. For
information on particular usages of this record for moisture, heat input, ARP units, NOx program

Specific Considerations
Moisture
• If required to correct for moisture (H2Q) when calculating emissions or heat input at a
monitoring location, report a separate monitor method record for the II20 parameter. Do
this for each location at which moisture is needed, defining the methodology used to
determine hourly moisture for emissions calculations.
Monitoring Plan Reporting Instructions — Page 36
Environmental Protection Agency
-------
6.0 Monitoring Method Data
September 17, 2014
Heat Input
• If heat input monitoring is required, there must be a separate monitor method record for
heat input (HI) data for each unit, even if the monitor location is not at the unit level. For
example, if SO2, CO2, NOx, and Flow monitors are installed at CS001, which serves Unit
1, 2, and 3, there will be a full set of monitor method records for CS001 and only one
monitor method record for HI at each unit. The unit records for monitor method should
indicate that the heat input is calculated for the unit, using the "CALC" monitoring
method code.
Acid Rain Program Units
• If a location which has an SO2 monitor combusts both high sulfur fuel (e.g., coal or oil)
and a low sulfur fuel, and uses a default SO2 emission rate in conjunction with Equation
F-23 for hours in which very low sulfur fuel is combusted (see §75.11(e)(1)), report one
monitor method record for parameter S02 with a monitoring methodology code
CEMF23. If only low-sulfur fuel is combusted and the F-23 calculation is used for every
hour, report the SO2 monitoring method as F23.
• If a unit or stack is exempt from opacity monitoring, report a monitor method record for
the unit or stack defining the parameter OP with a monitor method code of EXP.
• If opacity is monitored at a common stack or multiple stacks, but no other parameters are
monitored at that location, do not define the stack(s). Instead, report the opacity method
and system data at the unit level.
• If a unit is also subject to Subpart H, be sure to include the appropriate method record(s)
indicating how NOx mass is determined.
NOx Program Units
• Report a monitor methodology record for parameter NOX at each applicable location.
• Report the method code as NOXR if NOx mass emissions are calculated by determining
NOx emission rate and heat input rate. Report method code CEM if NOx mass is
calculated as the product of NOx concentration and stack gas flow rate.
• If applicable, report methodology records for NOx emission rate and/or heat input.
Hg Program Units (MATS Rule):
• Report a monitoring methodology record for parameter HGRE or HGRH at each
applicable location where the Hg emission rate is continuously monitored.
• If you plan to install, certify and operate a backup Hg monitoring system using a different
monitoring methodology other than the primary system, (e.g., where Hg CEMS is used as
the primary monitoring system and a sorbent trap system is used as a redundant backup),
report the combination method code (CEMST). The backup system may only be used for
Environmental Protection Agency

reporting Hg concentration during operating hours in which the primary Hg system is not
available.
S02, HC1 and HF Program Units (MATS Rule):
Report a monitoring methodology record for parameter S02RE, S02RH, HCLRE, HCLRH,
HFRE, or HFRH (as applicable) at each location where the S02, HC1, or HF emission rate is
continuously monitored.
Low Mass Emissions (LME) Units
For all LME units as under the methodology in §75.19:
• For Acid Rain Program LME units: Submit separate monitor methodology records for
parameters S02M, NOXM, C02M, HIT, and, if applicable OP.
• For Non-Acid Rain LME Units: Submit monitor method records to describe the
methodologies for both NOx mass (NOXM) and heat input (HIT).
Part 75 Alternative Monitoring System (AMS)
• The use of method code AMS for determining average hourly emissions for parameters
C02, HI, NOX, NOXR, or S02 is granted through petition based on meeting the
requirements of Subpart E of Part 75.
Updating the Monitoring Method Data Record
When changing monitoring methodologies for a parameter, report both the old and new
Monitoring Method Data records. First, close out the existing monitoring methodology
record by entering the date and hour that the methodology was discontinued (EndDate,
EndHour). Second, create a new monitoring method record for that parameter indicating the date
and hour during which use of the replacement methodology began (BeginDate, BeginHour). For
the new method, leave the values for End Date and End Hour blank.
(Note: For EGUs subject to the MATS rule, if CEM, ST, or CEMST is the old methodology for
Hg emission rate, or if CEM is the old methodology for HC1, HF, or SO2 emission rate and you
switch to another compliance methodology for acid gases or HAP metals (e.g., periodic stack
testing), close out the existing Monitoring Method Data record by entering the date and hour
that the methodology was discontinued (EndDate, EndHour). Then, EPA strongly encourages
you to create a new, optional supplemental mats compliance Method Data record, as
described in section 6.1.
In order to correct a previously submitted record that contains erroneous information, resubmit
that Monitoring Method Data record with the corrected information. For example, if the SO2
Monitoring Method Code was previously submitted as "CEM" and the correct code should have
been "CEMF23," the record should be updated and resubmitted. Note that the BeginDate and
BeginHour elements should not be updated, unless the BeginDate and/or BeginHour are the
elements to be corrected.

6.1 Supplemental MATS Compliance Method Data
Begin Date
Element Name: BeginDate
Report the date on which the compliance method is first used at the monitoring location.
For new units, report the first date on which the compliance method is expected to be used.
Correct as needed when the actual begin date is known.
Begin Hour
Element Name: BeginHour
Report the hour in which the compliance method is first used at the monitoring location.
End Date
Element Name: EndDate
Report the date on which the compliance method is last used at the monitoring location. Leave
this field blank for active records.
End Hour
Element Name: EndHour
Report the hour in which the compliance method is last used at the monitoring location. Leave
this field blank for active records.
Specific Considerations
• For Hg, LEE status is available only for existing EGUs. For all other parameters, LEE
status is available for both new and existing EGUs.
• For all parameters except Hg, you must obtain 3 years of performance test data showing
that the emissions are < 50% of the standard to qualify for LEE status.
Updating the Supplemental MATS compliance Method Data Record
When you change the compliance method for a parameter, report both the old and new
supplemental mats compliance Method Data records, except as described in the Note,
below. First, close out the existing record by entering the date and hour that the compliance
method was discontinued (EndDate, EndHour). Second, create a new record, indicating the date
and hour at which use of the replacement compliance method began (BeginDate, BeginHour). In
the new supplemental mats compliance Method Data record, leave the values for End
Date and End Hour blank.
In order to correct a previously submitted supplemental mats compliance Method Data
record that contains erroneous information, resubmit that record with the corrected information.

Description of Data
The Component Data record describes each of the components used to make up the monitoring
systems defined in the monitoring plan. A component can be either a hardware component, such
as a NOx analyzer, or a software component, such as a DAHS. Under most circumstances, only
one Component Data record is required for components that are shared by multiple monitoring
systems defined at that location. For example, an O2 monitor that is used in both the NOx
emissions rate system and the moisture monitoring system needs only to be identified in one
Component Data record. The exception exists for a combined cycle combustion unit using a
"time-share" CEMS configuration to monitor emissions from both the main and bypass stacks.
Please refer to "Specific Considerations" below for more information.
Information describing the monitoring system of which the component is a part is not needed for
this record. The relationship between components and monitoring systems is defined by the
Monitoring System Component Data record.
For information on defining DAHS components, how to report fuel flowmeter data when using
flowmeter rotation, and how to represent manufacturer and serial number information, refer to
"Specific Considerations" below.

Dependencies for Component Data
The Component Data record is dependent on the Unit Data record or the Stack Pipe Data
record.
The following records are dependent upon the Component Data record:
• Analyzer Range Data
• Monitoring System Component Data
Component Data Elements
Instructions for completing each element of the Component Data section are provided below:
Component ID
Element Name: ComponentID
Report the three-character ID assigned to the component. This ID is assigned by a source and
must be unique to a stack, pipe, or unit. For example, two different monitored units or stacks,
e.g., CS1 and CS2, could each have an O2 monitor with the same assigned Component ID of 123.
However, no two components at the same monitored location (in this case, either CS1 or CS2)
are allowed to have the same Component ID. For temporary like-kind analyzer replacements
under §75.20(d), the component ID of the like-kind analyzer must begin with the prefix "LK"
(e.g., "LK1," "LK2," etc.).
Note that components are linked to each system that the component serves using the
Monitoring System Component record. The Monitoring System Component record
includes a begin date and hour to track when a particular component is placed into service as part
of the system, and an end date and hour to indicate when the component is removed or is
replaced.
Do not close out primary monitoring components that are temporarily removed from service for
maintenance, e.g., when a like-kind monitoring component is placed into service while the
primary component is being repaired.
Also, do not close out temporary like-kind replacement analyzer ("LK") components unless a
particular like-kind analyzer will never be used again at the unit or stack location. You may
represent the "LK" analyzer in the monitoring plan as an active component of the primary
monitoring system, for the entire useful life of the LK analyzer.

Specific Considerations
Essential DAHS Components (Software and Hardware)
• Identify the software component(s) of the Data Acquisition and Handling System
(DAHS) as individual components. Any software program that calculates emissions or
heat input rate, or implements missing data substitution algorithms or quarterly reporting
functions should be defined as a component. Identify the programmable logic controller
(PLC) or automated data logger (DL) as a system component if it performs any of those
functions.
Non-Essential Software or Hardware Components
• Software or hardware components that perform the following functions do not have to be
identified as part of the DAHS and therefore do not need component definitions1:
— Calculation of RATA results;
— Calculation of flow-to-load results (that are merged with the final quarterly report); or
— Recording of operating parameters (that are merged with the final quarterly report),
e.g., unit load.
Rotating Fuel Flowmeters
When fuel flowmeters are rotated among different units to facilitate the removal of meters for
accuracy testing (e.g., three fuel flowmeters rotated between two units), submit a new
monitoring system component data record each time that a fuel flowmeter is being placed
into service, and update the end date and hour of the monitoring system component data
record for the fuel flowmeter that is being removed. Use the reinstallation date and hour in the
fuel flowmeter accuracy data record as the begin date and hour in the new monitoring
system component data record, and use the hour prior to the reinstallation date and hour as the
end date and hour in the monitoring system component data record for the fuel flowmeter
that is being removed. If the fuel flowmeter that is being placed into service had previously been
installed, you may report its previously assigned component ID in the monitoring system
COMPONENT DATA record or you may assign a new component ID.
The rotation of dilution probes should be reported in the same manner as fuel flowmeters.
1 While these components do not have to be identified in the monitoring plan, identify them in the data flow
diagram under § 75.53(c)(5)(iii) and/or the quality assurance plan under Appendix B to Part 75.

Manufacturer and Serial Number Data for DAHS Components
• Use an abbreviation that clearly identifies the utility or operating company responsible
for the software development if software has been developed in-house. Use the same
abbreviation or name in the Manufacturer field for all units and sources using the
software.
• Serial numbers are optional for DAHS software components and billing fuel flowmeters.
If choosing to assign one, it must be unique to the software installation.
Time-Share CEMS on Single Unit
When using a "time-share" CEMS configuration to monitor emissions from both the main stack
and bypass stack for a combined cycle combustion unit using a single monitoring location,
define separate systems with unique Monitoring System IDs for each effluent point, and define
separate component records with unique Component IDs for each system. Defining separate
components for each system will allow for the tracking of component specific tests (e.g.,
linearity, seven day cal, online offline cal, and cycle time) where the test cannot be otherwise
uniquely identified. (This is a distinct change from the previous EDR format, where it was
acceptable to include the same component in both systems, since the Monitoring System ID used
to be included in the test record.) If the same component was previously reported in both
systems, EPA recommends that affected units define new component records only for the system
that represents the monitoring of the bypass stack, so as to minimize the amount of data that
would need to be resubmitted. The most recent component specific QA test data (previously
submitted under the old format) will need to be resubmitted under the new Component IDs.
Manufacturer, Model, and Serial Number for STRAIN components
When reporting the Manufacturer, Model Number, or Serial Number for STRAIN components,
report the Sample Gas Flow Meter manufacturer, model number, and serial number. Do not
report the numbers, etc. associated with the sorbent traps or other associated hardware.

Description of Data
Submit a Monitoring System Data record to define each monitoring system that is installed
(or will be installed) at each monitoring location in the monitoring plan. For continuous
emission monitoring methodologies, a monitoring system is any combination of analytical
components, sensors, and data software components for which a relative accuracy test is
required (i.e., SO2 concentration system, Hg CEMS, HC1 CEMS, HF CEMS, sorbent trap
monitoring system, flow rate system, NOx diluent system, NOx concentration system, O2
concentration system, CO2 concentration system, or moisture system, as applicable). For
monitoring methodologies based on fuel flow metering, a monitoring system consists of the
fuel flowmeter component(s) and the software component(s) needed to calculate and report
hourly fuel flow for a unit or common pipe for a particular fuel. See the "Specific
Considerations" section below for more detailed information about system types.
Information describing the monitoring system's individual components is not needed for this

Specific Considerations
Characteristics of Monitoring Systems
• Monitoring systems are generally comprised of the actual, physical components that are
installed or will be installed for a unit, pipe, or stack where the measurement equipment
is installed. Each monitoring system either directly measures a specific emissions
parameter (for example, NOx emission rate) or provides a parameter necessary for
calculating emissions (for example, pollutant concentration, stack flow, moisture, or
mass oil flow). A monitoring system can include both hardware and software
components.
• CEM Systems must include the probe component in addition to the analyzer(s) and
DAHS software.
Monitoring Plan Reporting Instructions — Page 60

8.0 Monitoring System Data
September 17, 2014
Types of Systems Which May Be Defined and Used
• CO2 or O2 System. A CO2 monitoring system may be used to: (1) measure percent
CO2 to determine CO2 mass emissions; or (2) determine hourly heat input rate (in
conjunction with a flow monitoring system). O2 monitoring systems are only used for
determining hourly heat input rate. A CO2 or O2 system is comprised of a CO2 or O2
analyzer and a DAHS software component. When using Equation F-14A or F-14B to
convert a measured O2 value to CO2 for purposes of determining hourly CO2 mass
emissions, define a CO2 monitoring system containing an O2 component and DAHS
software. A probe component must be added to the system when the sample
acquisition method of the CO2 or O2 System is either dilution (DIL), dilution in-stack
(DIN), dilution out-of-stack (DOU), dry extractive (EXT), or wet extractive (WXT).
• Flow Monitoring System. This monitoring system is used to measure stack flow rate in
standard cubic feet per hour (scfh). The flow rate is used to calculate heat input rate
and/or SO2, CO2, and/or NOx mass emissions. At a minimum, the system is comprised
of a flow monitor and DAHS software. For flow monitors, identify a single component
as representative of the control unit of the monitor. If the average of two or more flow
monitors will be used to determine the hourly flow value, identify each separate flow
monitor as a component in the flow monitoring system.
• Gas Fuel Flow System. This monitoring system measures gas flow rate in 100 standard
cubic feet per hour. Gas flow rate is used to calculate SO2 and CO2 mass emissions
and/or heat input rate. At a minimum, this system is comprised of a gas fuel flowmeter
and DAHS software.
• Moisture System. This system is used to measure hourly percent moisture for the
calculation of hourly heat input rate, NOx emission rate, NOx mass emissions, CO2
mass emissions, or SO2 mass emissions, if an hourly moisture adjustment is required
because component monitors use different moisture bases. A moisture system may be
comprised of a moisture sensor and DAHS software or one or more dry and wet basis
oxygen analyzers and DAHS software. One of these oxygen analyzers may also be a
component of the NOx-diluent system described below. For units with saturated gas
streams (e.g., following a wet scrubber, it is also possible to use a moisture system
comprised of a temperature sensor and a moisture look-up table. This type of system is
represented by a single DAHS software component (note that this is the same DAHS
component that is listed as a component of the other monitoring systems at the unit or
stack).
• Long Term Gas or Oil Fuel Flow System. These monitoring systems are for low mass
emissions (LME) units only. They measure fuel flow on a long term (non-hourly)
basis, for the purpose of quantifying unit heat input. The systems are comprised of
DAHS software components and, depending on the methodology selected, may also
include Appendix D or billing fuel flowmeters or other relevant components. These
systems are used in conjunction with default or unit-specific, fuel-specific emission

8.0 Monitoring System Data
• NOx-Diluent System. This monitoring system is used to determine NOx emission rate in
lb/mmBtu. It is comprised of a NOx concentration monitor, a CO2 or O2 diluent
monitor, and DAHS software. A probe component must be added to the system when
the sample acquisition method of the NOx-Diluent System is either dilution (DIL),
dilution in-stack (DIN), dilution out-of-stack (DOU), dry extractive (EXT), or wet
extractive (WXT).
• Appendix E NOx System (NOXE). This monitoring system is used to determine NOx
emission rate in lb/mmBtu based on a NOx/heat input rate correlation curve derived
from emission testing. Each NOXE system represents a single correlation curve (either
for a single fuel or for a consistent mixture of fuels) and is comprised of the DAHS
software component. Appendix E systems are associated with a unit, not with multiple
or common stacks.
• NOx Concentration System. This monitoring system is used to determine NOx
concentration, and is used in conjunction with a separately certified flow monitoring
system to calculate NOx mass emission rate (lb/hr). It is comprised of a NOx
concentration monitor and DAHS software. A probe component must be added to the
system when the sample acquisition method of the NOx Concentration System is either
dilution (DIL), dilution in-stack (DIN), dilution out-of-stack (DOU), dry extractive
(EXT), or wet extractive (WXT).
• N()x Predictive Emissions Monitoring System. This type of monitoring system must be
approved by petition under §75.66 and Subpart E of Part 75. It is used to determine
NOx emission rate for a gas or oil-fired turbine or boiler and is comprised only of a
DAHS software component (or components).
• Volumetric Oil Fuel Flow System. This monitoring system measures hourly volumetric
oil flow rate. Oil flow rate is used to calculate SO2 and CO2 mass emissions and/or
heat input rate. At a minimum, it is comprised of an oil fuel flowmeter and DAHS
software.
• Mass Oil Fuel Flow System. This monitoring system measures hourly mass of oil
combusted in pounds per hour. Oil flow rate is used to calculate SO2 or CO2 mass
emissions and/or heat input rate. At a minimum, it is comprised of an oil fuel
flowmeter and DAHS software.
• Opacity System. This monitoring system is used to determine the opacity of emissions.
It is comprised of a continuous opacity monitor (COM) and DAHS software.
• Particulate Matter Monitoring System. This monitoring system is used to continuously
monitor particulate emissions. Affected units with a particulate monitoring system are
exempt from opacity monitoring under Part 75.
• SO2 Concentration System. This monitoring system is used to measure SO2
concentration. It is used in conjunction with a flow monitoring system to determine
hourly SO2 mass emission rates in lb/hr. The system consists of an SO2 concentration
monitor and a DAHS software component. A probe component must be added to the

system when the sample acquisition method of the SO2 Concentration System is either
dilution (DIL), dilution in-stack (DIN), dilution out-of-stack (DOU), dry extractive
(EXT), or wet extractive (WXT).
• Hg Concentration System. This monitoring system is used to measure hourly Hg
concentration in units of ng/scm. It is used in conjunction with auxiliary measurements
(i.e., stack gas flow rate, diluent gas concentration, stack gas moisture content,
electrical output, as applicable) to determine hourly Hg mass emission rates in units of
lb/TBtu or lb/GWh. The monitoring system consists of a Hg pollutant concentration
monitor, and a DAHS software component. A probe component must be added to the
system when the sample acquisition method of the Hg Concentration System is either
dilution (DIL), dilution in-stack (DIN), dilution out-of-stack (DOU), dry extractive
(EXT), or wet extractive (WXT).
• Sorbent Trap Monitoring System. This monitoring system is used to determine Hg
concentration in units of ng/dscm. Paired sampling trains are used to collect vapor
phase Hg over a discrete period of time (up to 14 operating days), using sorbent traps
that contain a suitable adsorbing medium (e.g., halogenated carbon). The total volume
of dry gas sampled by each train during the collection period is measured. After the
traps are removed from service, they are analyzed to determine the mass of Hg
collected. The Hg mass collected by each train is used together with the dry gas sample
volume to determine an Hg concentration value. Generally speaking, the two Hg
concentrations are averaged and the average value is assigned to each operating hour of
the sampling period. This average concentration is used in conjunction with auxiliary
measurements (i.e., stack gas flow rate, diluent gas concentration, stack gas moisture
content, electrical output, as applicable) to determine hourly Hg mass emission rates in
units of lb/TBtu or lb/GWh. The monitoring system consists of two sampling train
components (each one representing a sorbent trap and the associated sample gas flow
meter) and a DAHS component.
• HCl Concentration System. This monitoring system is used to measure hourly HC1
concentration in units of ppm. It is used in conjunction with auxiliary measurements
(i.e., stack gas flow rate, diluent gas concentration, stack gas moisture content,
electrical output, as applicable) to determine hourly HCl mass emission rates in units of
lb/mmBtu or lb/MWh. The monitoring system consists of a HCl pollutant
concentration monitor, and a DAHS software component. A probe component must be
added to the system when the sample acquisition method of the HCl Concentration
System is either dilution (DIL), dilution in-stack (DIN), dilution out-of-stack (DOU),
dry extractive (EXT), or wet extractive (WXT).
• HF Concentration System. This monitoring system is used to measure hourly HF
concentration in units of ppm. It is used in conjunction with auxiliary measurements
(i.e., stack gas flow rate, diluent gas concentration, stack gas moisture content,
electrical output, as applicable) to determine hourly HF mass emission rates in units of
lb/mmBtu or lb/MWh. The monitoring system consists of a HF pollutant concentration
monitor, and a DAHS software component. A probe component must be added to the
system when the sample acquisition method of the HF Concentration System is either

OILM, OILV, and GAS Systems
• If different types of oil or gas are burned in one unit, define a separate oil or gas system
for each type of fuel combusted in the unit.
• Each oil or gas system must include at least one fuel flowmeter hardware component.
Each oil and gas system must also include a DAHS component to record and calculate
fuel flow and heat input and to perform missing data substitutions.
• The oil or gas system for the unit or common pipe must include all fuel flowmeters that
are necessary to determine net fuel flow for one type of fuel. For example, if net oil
flow is measured by using one flowmeter for the main fuel line to the unit and
subtracting the value measured by the flowmeter on the return fuel line, the system
must include both the main and return flowmeters as separate components of the same
system. If more than one pipe supplies the same type of fuel to a unit and separate fuel
flowmeters are installed on each of the pipes (e.g., for a combined cycle turbine with a
duct burner), all the flowmeters measuring that one fuel are considered separate
components of the same system.
Low Mass Emissions Units (LMEs)
• For low mass emissions units reporting under §75.19, do not define monitoring
systems, and do not report this record unless long term fuel flow monitoring systems
are used to measure fuel flow and heat input.
• For a group of oil or gas-fired LME units served by a common pipe (or supply tank),
define a LTOL or LTGS monitoring system for the pipe or tank. In both cases (i.e., for
common pipe or tank), the pipe or tank ID number must begin with a "CP" prefix (e.g.,
CP001). If two or more common pipes or tanks of different fuel types supply the same
group of LME units, define a separate LTOL or LTGS system for each pipe or tank. If
two or more pipes or tanks supply the same type of fuel to a group of LME units, define
a single LTOL or LTGS system.
Monitoring System Data Updates
If changes must be made to key data fields and/or a system must be redefined after that system
has been certified and used to report emissions, recertification testing may be required. If it is
necessary to make such changes and it is unclear what testing or other requirements may be
associated with that change, consult with EPA or the applicable state agency.

This record links individual monitoring components to each monitoring system in which they
serve and defines the time frame for that relationship. Report a Monitoring System
Component Data record for each system-component relationship. See the descriptions for each
type of monitoring system in the instructions for the Monitoring System Data record for
general information about what components to include in each system.
Except for primary monitoring systems containing like-kind replacement ("LK") components, a
system should not contain any active components that are not in service when the system is being
used to monitor and report data. For example, do not include backup DAHS software as an
additional DAHS component of a primary system. If you have defined primary SO2 system 101,
consisting of a SO2 concentration monitor (component ID SOI) and a DAHS software
installation (component ID D01), and you also have a second installation of that DAHS software,
you should define a separate Data Backup (DB) SO2 monitoring system.

Description of Data
The Monitoring Formula Data record is used to identify the formulas that will be used to
calculate required data from the monitoring systems defined in the Monitoring System Data
record. It is not necessary to define formulas referencing backup monitoring systems unless the
backup monitoring systems use different formulas than the primary system.
Monitoring Formula Data are used for three primary purposes:
• To verify that the formulas selected are appropriate to the monitoring approach and
reflect a thorough understanding of emissions calculations and the use of appropriate
variables;
• To provide the basis for formula verification to ensure that the DAHS software calculates
emissions and selected values accurately; and
• To verify hourly calculations in quarterly reports.
Dependencies for Monitoring Formula Data
The Monitoring Formula Data record is dependent on the Unit Data record or the Stack

Because the fuel usage time may not be equal to the unit operating time, the hourly C02 rate for the feel may be
different from the hourly C02 rate for the unit. Use formula G-4A to calculate the unit hourly CGI rate.

Specific Considerations
Required Formulas
• Depending on the monitoring methodologies and component types in use, include in the
monitoring plan one or more of the following formulas:
• For CEMS Based Methodologies
— SO2 mass emission rate
— NOx emission rate
— NOx mass emission rate
— CO2 concentration (if CO2 is calculated from O2 data)
— CO2 mass emission rate
— Hg emission rate
— HC1 emission rate
— HF emission rate
— SO2 emission rate (MATS)
— Heat input rate
— F-factor proration calculation for mixed fuels (if elected)
— Flow-weighted or heat input-weighted NOx emission rate formulas for multiple stacks
using two primary NOx systems
— Moisture formulas for moisture systems using O2 wet and dry readings
— Flow formulas for all flow systems containing two flow monitors
Monitoring Plan Reporting Instructions ~ Page 98
Environmental Protection Agency
-------
9.0 Monitoring Formula Data
September 17, 2014
• For Fuel Flow Based Methodologies
— SO2 mass emission rate (ARP)
— CO2 mass emission rate (ARP)
— NOx emission rate for the unit where separate Appendix E single fuel curves were
used (Equation E-2)
— Heat input rate
— Mass of oil formulas for OILV measurements (ARP)
— Net fuel flow formulas for systems with more than one flowmeter
— F-factor proration calculation for mixed fuels (if elected)
F-Factors and F-Factor Formulas
• Heat input rate, NOx emission rate, and CO2 emission rate formulas based on CEMS
require the inclusion of a specific F-factor based on the fuel being combusted. If a
combination of fuels may be combusted within any given hourly period, two options for
calculating emissions are available: (1) use the highest F-factor, or (2) use a prorated F-
factor. Calculate prorated F-factors using Equation F-8 in 40 CFR Part 75, Appendix F.
If a pro-rated F-factor formula is used, include it in this data set.
Equations 19-3D and 19.5D
• For units that use Equation 19-3 or 19-5 to calculate NOx, SO2, Hg, HC1, or HF emission
rate (lb/mmBtu) during normal unit operation, if the O2 diluent cap value is applied
during startup and shutdown hours, you must use Equation 19-3D instead of Equation
19-3 or Equation 19-5D instead of Equation 19-5 (as applicable) for each hour in which
the diluent cap is used, to avoid generating negative NOx, SO2 , Hg, HC1, or HF emission
rates.
Situations That Do Not Require Formulas
• Appendix E units do not need formulas for the NOx emission rate.
• Units using LME methodology in §75.19 do not need formulas.
• Do not include formulas for cumulative quarterly or annual emissions or heat input.
• Do not provide formulas representing the default heat input rate or default NOx emission
rate for the unit or stack.

Description of Data
Monitoring Default Data records define Maximum Values, Minimum Values, Defaults, and
Constants that are used in the Part 75 calculations or in the missing data routines. Report one
record for each fuel type and parameter combination to define the applicable emission factor,
moisture content, maximum potential value or diluent cap to be used at a monitoring location, as
described below.
Monitoring Default Data records are required for the following situations:
Missing Data Defaults (DefaultPurposeCode "MD")
• Maximum NOx emission rate (MER) for any location using a NOx-diluent monitoring
CEM system.
• Maximum controlled NOx emission rate (MCR) for bypass stacks or missing data
substitution for hours in which the add-on controls are documented to be operating
properly (see §§75.17(d), 75.31(c)(3), and 75.34(a)(5)).

potential NOx emission rates (MERs), or maximum potential flow rates (MPFs), for units
using fuel-specific CEMS missing data option under §75.33.
• Fuel-specific maximum potential SO2 or NOx concentrations or maximum potential NOx
emission rates, for units with add-on emission controls and unmonitored bypass stacks, if
the fuel-specific MPC or MER is reported during hours when the flue gases are routed
through the bypass stack and the add-on controls are either bypassed or not documented
to be operating properly (see §§75.16 (c)(3) and 75.17 (d)).
• Fuel-specific maximum controlled NOx concentrations or maximum controlled NOx
emission rates (MCR), for units with add-on emission controls and unmonitored bypass
stacks, if the fuel-specific MEC or MCR is reported during hours when the flue gases are
routed through the bypass stack when the add-on emissions controls are not bypassed, are
in use, and are documented to be operating properly (see §75.17 (d)).
• Generic NOx emission rate defaults for low mass emissions units. Use this value when
NOx controls are not operating or when default has expired.
• Maximum potential NOx concentration and emission rate for Appendix E units. Use
maximum emissions rate when NOx controls are not operating, when burning emergency
fuels, or when Appendix E curve has been invalidated or has expired.
• Maximum or minimum potential moisture percentage (required only if monitoring
moisture continuously or using a moisture look-up table). Used for missing data
purposes.
• Minimum emission values for subtractive stack situations, if approved by petition.

Moisture Defaults
If using a default value to determine moisture, report fuel-specific moisture default values.
Tables 49 and 50 provide the fuel-specific moisture default values for coal-fired and wood-
burning units and natural gas-fired boilers. Table 49 provides minimum default moisture values
that are used in all emission (SO2, NOx, CO2) and heat input rate calculations requiring moisture
corrections, except for calculation of NOx emission rates using Equation 19-3, 19-4, or 19-8 from
EPA Method 19 in Appendix A-7 to 40 CFR 60. If Equation 19-3, 19-4, or 19-8 is used to
calculate NOx emission rate, SO2 emission rate, HC1 emission rate, HF emission rate, or Hg
emission rate, use the appropriate maximum default moisture value from Table 50.
If using a monitoring system to determine moisture, report either the maximum or minimum
potential moisture percentage, depending on whether you use the standard or inverse missing
data procedure from Part 75. For the minimum potential moisture percentage, report either a
default value of 3.0 percent H2O or a site-specific value obtained from 720 or more hours of
historical data. For the maximum potential moisture percentage, report either a default value of
15.0 percent H2O or a site-specific value derived from 720 or more hours of historical data.

Table 51 contains tlie "generic" default NOx emission factors for qualifying oil and gas-fired low
mass emissions units under §75.19. which are based on the unit type and the type of fuel
combusted. Unit and fuel-specific NOx emission rates may be determined for low mass
emissions units by emission testing, in lien of using the defaults in Table 51.
For fuel oil combustion, in lieu of using the default values in Table 52, fuel and unit-specific
default S02 emission rates may be determined based on the maximum allowable weight
percentage of sulfur in the fuel, as specified in the operating permit (see §75.19(c)(l)(i)). For
gaseous feels other tlian natural gas, there are no generic default values available. Therefore,
fuel and unit-specific emission rates must be determined for all emission parameters.

Specific Considerations
Situations Not Requiring Monitoring Default Data Submission
• Values for CO2 or O2 used to calculate the maximum potential velocity (MPV), which is
used to determine the flow rate span value. Submit the information to support flow span
calculations in hardcopy with the initial monitoring plan (and store on site). Do not
report this information electronically in the EDR.
• Maximum oil and gas fuel flow rate. These values are defined in System Fuel Flow
Data.
• Maximum potential (or maximum expected) SO2, NOx, CO2, or flow rate values, for units
using the standard (non-fuel-specific (NSF)) CEMS missing data routines in §75.33.
(These maximum potential and expected values are defined in Monitor Span Data.)
• Default high range value for SO2 or NOx (already defined in monitor span).
• Default SO2 emission rates for Acid Rain Program units that use Appendix D to account
for SO2 mass emissions from the combustion of gaseous fuel. For these units, report the
default SO2 emission rates in the Parameter Fuel Flow Data record.
• Appendix D density and GCV values for oil and gas. These values are defined in the
Fuel Flow Data record.
Specific Considerations for Units Using Equation F-23
• For pipeline natural gas combustion, report 0.0006 lb/mmBtu.
• For other natural gas combustion, report the default SO2 emission rate (lb/mmBtu)
calculated using Equation D-lh.

September 17, 2014
MPC Value
Element Name: MPCValue
In the high scale record for NOx, SO2, or CO2, report the Maximum Potential Concentration
(MPC) value for the location. Report MPC for NOx, SO2, and Hg to one decimal place. For O2,
leave this field blank.
MPF Value
Element Name: MPFValue
If the span record is for parameter FLOW, report the Maximum Potential Flow (MPF) value for
the monitoring location in standard cubic feet per hour (scfh) on a wet basis.
Span Value
Element Name: SpanValue
Report the Span Value determined according to the requirements of Part 75 or (if applicable) 40
CFR Part 63, Subpart UUUUU. If using a default high range value for SO2 or NOx, leave this
field blank in the high scale record.
For Hg, determine the span value as follows. Multiply the Hg concentration (|ig/scm)
corresponding to the emission standard by two and round off the result to either: the next highest
integer; the next highest multiple of 5 |ig/scm; or the next highest multiple of 10 |ig/scm.
For SO2 and NOx, high-scale span values must be between 100 percent and 125 percent of the
maximum potential concentration, rounded up to the next highest multiple of 100 ppm (or,
alternatively, rounded up to the next 10 ppm if 125 percent of MPC is less than 500 ppm). Low-
scale span values must be between 100 percent and 125 percent of MEC, rounded upward to the
next highest multiple of 10 ppm.
For flow rate, the span value is the calibration span value and must be reported in the units used
for daily calibrations. To determine the calibration span value for monitors that are not
calibrated in units of inches of H20, first convert the maximum potential velocity (MPV) from
units of wet standard feet per minute (wsfpm) to the units used for daily calibration. Multiply the
result by a factor no less than 1.00 and no more than 1.25 and round up, retaining at least two
significant figures. For flow monitors calibrated in inches of water, report the calibration span
value to two decimal places.
For CO2 and O2, report the appropriate percentage (see Part 75, Appendix A, §2.1.3), to the
nearest one percent CO2 or O2, not ppm.
Full Scale Range
Element Name: FullScaleRange
Report the full-scale range in the units used for daily calibrations for SO2, NOx, CO2, O2, and
flow rate. As a general guideline, select the range such that, to the extent practicable, the
majority of the readings obtained during normal operation of the monitor are between 20 and 80
percent of full-scale. See Section 2.1 of Appendix A to Part 75 for allowable exceptions to this

Specific Considerations
CEMS Methodology
• If you are using a CEMS methodology, Monitoring Span Data must be included for
each parameter (e.g., NOX, S02, C02, 02, HG, HCL, HF, or FLOW) that is measured
with CEMS.
• Note that for units that combust more than one type of fuel, the maximum potential
concentration (MPC) values reported in Monitoring Span Data are generally based on
the fuel that produces the highest pollutant concentration or emission rate. However, if
you elect to use one of the fuel-specific missing data options in §75.33, 75.16(c)(3), or
75.17(d)(2), in addition to reporting the "conventional" MPC or MER values for the
highest emitting fuel in Monitoring Span Data, you must report a fuel-specific
maximum potential value for each of the other fuels, using Monitoring Default Data.
Monitoring Plan Reporting Instructions — Page 126
Environmental Protection Agency
-------
11.0 Monitoring Span Data
September 17, 2014
Dual Ranges and Separate Monitoring Span Data Records
• If SO2, NOx, CO2, or O2 emission concentrations vary such that dual ranges are required
(e.g., due to fuel switching or emission controls), provide separate Monitoring Span Data
records for the low scale and high scale values.
High Scale and Low Scale Span Records
• If you elect to use a default high range value (200 percent of MPC for SO2 or NOx)
instead of calibrating and maintaining a high monitor range for hours in which emissions
exceed the full-scale of the low range, submit both high scale and low scale span records,
but in the high scale record, only report values for the following elements: the MPC,
Begin Date and Begin Hour, the activation date and hour of the default high range value,
and Default High Range (the default high range value of 200 percent of MPC).
DP-Type Flow Monitors Calibrated in Units of Inches of H2O
• For DP-type flow monitors that are calibrated in units of inches of H2O, select a value
between 100 percent and 125 percent of the MPV. Then convert that value from units of
wet, standard feet per minute (wsfpm) to units of wet actual feet per second (wafps).
Then use Equation 2-7 in EPA Reference Method 2 (40 CFR 60, Appendix A-l) to
convert the actual velocity to an equivalent delta-P value in inches of H2O. Retain at
least two decimal places in the delta-P value. In performing these calculations, the values
of stack temperature, stack pressure, stack gas molecular weight and the pitot tube
coefficient may be estimated based on the results of previous emission testing.
Updating the Monitoring Span Data Record
When any value in a Monitoring Span Data record changes, update the information by
reporting both the original span record with the appropriate end date and the new span record
with the appropriate begin date.
If you have discontinued the use of a default high range value for SO2 or NOx in favor of using a
span value, report in the old record the last date and hour on which the default high range was in
use. In the new record, report the date and hour on which the new span value became effective.
If changing from a span value to a default high range value for SO2 or NOx, report the date on

12.0 Rectangular Duct WAF Data

Rectangular Duct WAF Data XML Elements
Description of Data
Submit a Rectangular Duct WAF Data record for rectangular ducts or stacks with installed
flow monitors, in which a wall effects adjustment factor (WAF) was determined using
Conditional Test Method CTM-041 and applied to the hourly flow rate data. Conditional Test
Method CTM-041 is used to either:
• Determine a site-specific default WAF; or
• Make wall effects measurements and calculate an average WAF, based on three or more
test runs.
If you elect to measure wall effects, the measurements may be made at any load level (low, mid
or high) and may either be coupled with the test runs of a flow RATA or may be made
separately. Once a default or measured WAF has been determined, it may be entered into the
programming of the flow monitor as a correction to the cross-sectional area of the rectangular
stack or duct, thereby adjusting the measured stack gas flow rates for wall effects. Then, when a
Monitoring Plan Reporting Instructions — Page 128
Environmental Protection Agency
-------
12.0 Rectangular Duct WAF Data
September 17, 2014
subsequent RATA of the flow monitor is performed, the same WAF that is being used to correct
the flow monitor readings should be applied to the reference method test data.
All units/stacks currently applying a wall effects correction obtained using CTM-041 to flow rate
data must report a Rectangular Duct WAF Data record in each quarterly submission. For
units not presently applying a wall effects correction, if you intend to begin using a WAF, report
this record after the WAF has been determined and prior to the next quarterly file that uses that
WAF.
If a new WAF test has been performed (because the stack or ductwork is altered such that the
flow profile is significantly changed), report two Rectangular Duct WAF Data records: one
that ends the record that is no longer effective, and one that reports the new wall effects
adjustment factor data.
Dependencies for Rectangular Duct WAF Data
The Rectangular Duct WAF Data record is dependent on the Unit Data record or the
Stack Pipe Data record.
No other records are dependent upon the Rectangular Duct WAF Data record.

Monitoring Load Data Elements
Instructions for completing each element of the Monitoring Load Data section are provided
below:
Maximum Load Value
Element Name: MaximumLoadValue
This value is required for all units and all additional monitoring locations with the exception of
non-load based units. Define the maximum hourly gross load associated with the unit, stack, or
pipe at full capacity:
• For boilers and simple cycle turbines (including units with multiple stack exhaust
configurations), this value is based on one of the following: (1) the nameplate capacity;
(2) the nameplate capacity as derated; or (3) a value higher than nameplate, if the unit or
stack historically operates at levels exceeding nameplate.
• For common stack (or common pipe) configurations, the maximum load will be the
highest sustainable combined operating load for the units serving the common stack (or
pipe).
• For multiple stacks, report the maximum hourly gross load for the associated unit.
• Determine the total maximum hourly gross load according to the guidelines in the Part 75
Emissions Monitoring Policy Manual for combined cycle (CC) combustion turbine units.
For combined cycle combustion turbines where the HRSG produces steam, the equivalent
load for the HRSG must be included in the maximum hourly gross load determination.
Express the total unit load on a consistent basis, i.e., either in terms of electrical or steam
load.
• For units subject to the MATS rule that use CEMS or sorbent trap monitoring systems to
continuously monitor the Hg emissions rate in units of lb/GWh, or for MATS units that
use CEMS to continuously monitor the SO2, HC1, or HF emission rate in units of
lb/MWh:
(1) If, for Part 75 purposes, you report gross electrical load in megawatts (MW) in the
HOURLY OPERATING DATA records, report the maximum gross electrical load value in
MW in this field. In this case, the hourly load data stream, in megawatts, in the
HOURLY OPERATING DATA records will suffice for both Part 75 and MATS purposes.
Otherwise:
(2) If, for Part 75 purposes, you report steam load or mmBtu/hr in the HOURLY
OPERATING DATA records, report the maximum steam load or the maximum
mmBtu/hr value in this field (as applicable). However, for the purposes of the MATS
rule, you must report a second hourly load data stream, i.e., the equivalent hourly
gross electrical load in megawatts, in the HOURLY OPERATING DATA records.
• Leave this field blank for units that do not produce electrical or steam load.

TMs value is required for all units and all additional monitoring locations where load-based
missing data are used. Report the lower boundary of the range of operation for units that
produce electrical or steam load, in units of megawatts. 1000 lblir of steam or iniriBtu/hr of
steam, as appropriate.
For single units (including units that have a multiple stack exhaust configuration), report the
minimum safe, sustainable load for the unit.
For a common stack (or pipe), report the lowest safe, sustainable load for any of the units using
the stack (or pipe) as the lower boundary of the range of operation. Alternatively, for frequently
operated units discharging to a common stack (or using a common pipe), the sum of the
minimum safe, stable loads of the units serving the common stack (or pipe) may be reported as
the lower boundary of the operating range.
For multiple stacks, report, the minimum safe, stable load for the associated unit.
For lion load-based unitv report the lower boundary of the range of operation in terms of stack
gas velocity (ft/sec). as described in Section 6.5.2.1(a) of Appendix A.

Upper Operation Boundary
Element Name: UpperOperationBoundary
This value is required for all units and all additional monitoring locations where load-based
missing data are used. Report the upper boundary of the range of operation for units that
produce electrical or steam load, in units of megawatts, 1000 lb/hr of steam, or mmBtu/hr of
steam, as appropriate. The upper boundary of the range of operation must be equal to or less
than the maximum hourly gross load reported in the Maximum Load Value.
Report the maximum sustainable load for single units (including units that have a multiple stack
exhaust configuration), to either: (1) the nameplate capacity of the unit (less any physical or
regulatory deratings); or (2) the highest sustainable load, based on a minimum of four
representative quarters of historical operating data.
Report the sum of the maximum sustainable loads of all units using the stack (or pipe) for a
common stack (or pipe), as the upper boundary of the range of operation. If that combined load
is unattainable in practice, report the highest sustainable combined load, based on a minimum of
four representative quarters of historical operating data.
For multiple stacks, report the maximum sustainable load for the associated unit.
For non load-based units, report the upper boundary of the range of operation in terms of stack
gas velocity (ft/sec), as described in Section 6.5.2.1(a) of Appendix A.
Normal Level Code
Element Name: NormalLevelCode
This value is required for all units and all additional monitoring locations where load-based
missing data are used, except for peaking units or stacks linked to peaking units. Designate and
report the most frequently used load level ("L," "M," or "H") as the "normal" load level for units
that produce electrical or steam load, based upon the results of the historical load data analysis
described in Section 6.5.2.1(c) of Appendix A. For all SO2, NOx, and flow RATAs conducted at
the designated normal load, a bias test is required.
For non load-based units, designate the normal operating level based on knowledge of the unit
and operating experience with the industrial process.
Second Level Code
Element Name: SecondLevelCode
This value is required for all units and all additional monitoring locations where load-based
missing data are used, except for peaking units or stacks linked to peaking units. Report the
second most frequently used level based on the results of the historical load data analysis
described in Section 6.5.2.1(c) of Appendix A (for units that produce electrical or steam load),
or, based on knowledge of the unit and operating experience with the industrial process (for non
load-based units).

13.0 Monitoring Load Data
Second Normal Indicator
Element Name: SecondNormallndicator
This value is required for all units and all additional monitoring locations where load-based
missing data are used, except for peaking units or stacks linked to peaking units. For units that
produce electrical or steam load, based upon the results of the historical load data analysis, the
second most frequently used load level may be elected to be designated as an additional normal
load level. If you wish to designate the second most frequently used operating level as a second
normal level, report" 1" for this element. Otherwise, report "0". Note that if you designate the
second level as a normal level, you must perform a bias test for all SO2, NOx, and flow RATAs
conducted at this load level.
For non load-based units, a second normal operating level may be designated, based on
knowledge of the unit and operating experience with the industrial process.
Load Analysis Date
Element Name: LoadAnalysisDate
Report the year, month and day of the historical load data analysis (see Sections 6.5.2.1 (c) and
(d) of Appendix A) that defines the two most frequently used load levels, and the normal load
level(s) for units that produce electrical or steam load.
Leave this field blank for new units since no load analysis has yet been completed.
Leave this field blank for non load-based units.
Begin Date
Element Name: BeginDate
Report the date on which the load information became effective. For the initial load analysis at a
particular unit or stack, report the Begin Date as the first day of the quarter in which the data
analysis was performed (i.e., 2005-01-01 or 2005-04-01, etc.), rather than the actual date of the
analysis unless the two dates are the same. For records created to indicate a change to the load
information, this date should equal the load analysis date if the change is based on a new load
analysis. But, if you are simply electing to add a second normal load or to make minor
adjustments to the boundaries of the operating range, or updating other information that is not
dependent on the load analysis, the Begin Date may be later than the load analysis date.
For peaking units, report the later of: (a) the date of program participation; or (b) the date on
which peaking status was first claimed for the unit.
For non load-based units, report the date on which the determination of the operating range, the
most frequent operating level(s), and the normal operating level(s) is made.
Begin Hour

13.0 Monitoring Load Data
September 17, 2014
End Date
Element Name: EndDate
Report the last date on which the load information was in effect. Report an end date only when
another Monitoring Load Data record will be reported to provide a change to one or more
data elements, either because a new historical load data analysis was performed which indicated
a change, or because you elect to change the second normal load designation or the range of
operation. When this occurs, submit one Monitoring Load Data record with the results of the
previous load data analysis and report the end date in this field. Submit a second Monitoring
Load Data record with the results of the new load data analysis or choice, leaving this field
blank (see "Specific Considerations" below).
For non load-based units, report an end date only when a change in the manner of unit or process
operation results in a change in the operating range and/or the most frequently-used operating
levels, and/or the designated normal operating level(s). Should this occur, submit two
Monitoring Load Data records, one to deactivate the old information, and one to activate the
new information, as described immediately above for load-based units.
End Hour
Element Name: EndHour
Report the last date on which the load information was in effect. This value should be left blank
for active records.
Specific Considerations
Range of Operation for Electrical or Steam Load Units and Non Load-Based Units
• Monitoring Load Data defines the upper and lower boundaries of the "range of
operation" for the unit (or units, for a common stack or pipe). For units that produce
electrical or steam load, the range of operation extends from the minimum safe, stable
operating load to the maximum sustainable load, and provides the basis for defining the
low, mid, and high operating load levels. For non load-based units (e.g., cement kilns,
refinery process heaters, etc.), the range of operation extends from the minimum potential
stack gas velocity, in ft/sec (or, alternatively, from 0.0 ft/sec) to the maximum potential
velocity.
Purpose of Historical Load Data Analysis
• Monitoring Load Data is also used to report the results of an analysis of historical load
data for the unit or stack, as described in Part 75 (see Section 6.5.2.1(c) of Appendix A).
The results of the historical load data analysis provide the basis for: (1) defining the
normal operating load level (or levels) for the unit or stack; (2) determining the two
appropriate load levels at which to conduct annual two-load flow RATAs; (3)
determining, for multi-load flow RATAs, the two appropriate load levels at which to
calculate bias adjustment factors, when two load levels are designated as normal and a
normal load bias test is failed; and (4) determining the appropriate load level at which to
Environmental Protection Agency
Monitoring Plan Reporting Instructions ~ Page 137
-------
September 17, 2014
13.0 Monitoring Load Data
conduct the quarterly flow-to-load ratio test. Note that for peaking units, the historical
load data analysis is not required.
Historical Load Data Analysis for Non Load-Based Units
• Non load-based units are exempted from the historical load data analysis in Section
6.5.2.1 (c) of Appendix A. For these units, the most frequently used operating levels and
the normal operating level(s) are determined by the owner or operator, using sound
engineering judgment, based on operating experience with the unit and knowledge of the
industrial process.
Upper and Lower Boundaries for New or Newly-Affected Units
• For new or newly-affected units, in the initial monitoring plan submittal, use the best
available estimates of the upper and lower boundaries of the range of operation and
determine the normal load (or operating level) and the two most frequently-used load (or
operating) levels based on the anticipated manner of operating the unit. Report the date
of submittal of the initial monitoring plan or the date on which commercial operation of
the unit begins (whichever is earlier) in the Begin Date field.
Updating the Monitoring Load Data Record
When the manner of operating the unit(s) changes significantly, update the information in
Monitoring Load Data by submitting two Monitoring Load Data records. First, close out
the existing monitor load record by entering an end date and hour. Next, create a new monitor
load record indicating the Begin Date and Hour for the new record.
In order to correct a previously submitted record that contains erroneous information, resubmit
the Monitoring Load Data record with the corrected information. For example, if the Normal
Level Code was previously submitted as "FT (for high-load) when the normal load level should
have be "M" (for mid-load), the record should be updated and resubmitted. Note that the
BeginDate and BeginHour elements should not be updated, unless the BeginDate and/or
BeginHour are the elements to be corrected.
Once the operating range and normal load level(s) have been established, Part 75 does not
require repeating the historical load analysis unless a significant change in the manner of unit
operation occurs, which may result in a re-designation of the operating range and/or the normal
load level(s) and/or the two most frequently used load levels. At least two quarters of
representative data are required to document that such a change in unit operation has occurred.
If such a change has been determined, establish the new load information by creating a new
Monitoring Load Data record with the new information, and report the old record with the
appropriate End Date and End Hour (which must be just prior to the Begin Date and Begin Hour
of the new record).
If, however, you elect to repeat the load analysis periodically, e.g., prior to each annual RATA,
in order to confirm that nothing has changed (this is good practice, even though this is not
required by the regulation), do not change the Begin Date unless the new data analysis shows
Monitoring Plan Reporting Instructions — Page 138
Environmental Protection Agency
-------
13.0 Monitoring Load Data
September 17, 2014
that a re-designation of the operating range and/or the normal load and/or the two most
frequently-used load levels is necessary.
For peaking units, if peaking status is lost at the end of a year or ozone season, the Monitoring
Load Data record information must be deactivated as of December 31 (for a year-round
reporter) or September 30 (for an ozone season-only reporter) of that year. Then, you must
perform a historical load analysis and activate a new Monitoring Load Data record, as
described in the Load Analysis data element instructions above.
When transitioning from non-peaking status to peaking unit status at the beginning of a new
calendar year or ozone season, deactivate the existing Monitoring Load Data record, as of
December 31 of the previous year (for a year-round reporter) or September 30 of the previous
year (for an ozone season-only reporter). Then, activate a new Monitoring Load Data record,
as of January 1 of the current year (for a year-round reporter) or October 1 of the previous year
(for an ozone season-only reporter). A new load analysis is not required, because the whole
operating range is considered normal for a peaking unit. Therefore, in the new MONITORING
Load Data record, leave Normal Level Code through Second Level Indicator data elements
blank. A Monitoring Qualification Percent Data record must also be submitted, to claim
peaking unit status.
MATS Units Reporting Steam Load or mmBtu/hr for Part 75
If you seek to comply with one or more electrical output-based SO2, Hg, HF, or HC1 emission
rate limits under the MATS rule, you must report gross electrical load in megawatts. However,
if, for Part 75 purposes, you report steam load or mmBtu/hr in the HOURLY OPERATING DATA
records and in the MAXIMUM LOAD VALUE data elementof this section, you must report the
equivalent maximum gross electrical load (MW) in the MATS MAXIMUM LOAD VALUE data
element of this section. You must also report the equivalent hourly electrical load (MW) in the
MATS Hour Load data element in the HOURLY OPERATING DATA records.

Monitoring Qual LME Data Elements
Instructions for completing each element of the Monitoring Qual LME Data section are
provided below:
Qualification Data Year
Element Name: QualificationDataYear
Report the calendar year used for the measured, estimated, or projected SO2 and/or NOx mass
emissions.
Operating Hours
Element Name: OperatingHours
Report the number of unit operating hours (as defined in §72.2) for the Qualification Data Period
(i.e., full year or ozone season) in the Qualification Data Year.
SO2 Tons
Element Name: SO2 Tons
If this record is linked to a Monitoring Qualification Data record with a
QualificationTypeCode of "LMEA", and the unit is subject to an SO2 program, report the SO2
mass emissions for the Qualification Data Year based on either measured or estimated SO2 mass
emissions or projected SO2 mass emissions, as appropriate according to § 75.19. Round and
report this value to one decimal place.
Otherwise, leave this field blank.
NOx Tons
Element Name: NOxTons
If this record is linked to a Monitoring Qualification Data record with a
QualificationTypeCode of "LMEA", and the unit is subject to a NOx program and is reporting
year-round, report the annual NOx mass emissions for the Qualification Data Year based on
either measured or estimated NOx mass emissions or projected NOx mass emissions, as
appropriate according to §75.19. Round and report this value to one decimal place.
If this record is linked to a Monitoring Qualification Data record with a
QualificationTypeCode of "LMES", and the unit is subject to an ozone-season NOx program,
report the seasonal NOx mass emissions for the Qualification Data Year based on either
measured or estimated NOx mass emissions or projected NOx mass emissions, as appropriate
according to §75.19. Round and report this value to one decimal place.
Otherwise, leave this field blank.

14.1 Monitoring Qual LME Data
Specific Considerations
SO2 Mass Emissions Reduction Program Units
• Use this record type to qualify as a low mass emissions unit by demonstrating that the
unit emits no more than 25 tons of SO2 per year.
NOx Mass Emissions Reduction Program Units
• For a unit subject to a program with a seasonal NOx emission cap, use this record type to
qualify as a low mass emissions unit by demonstrating that the unit emits no more than
50 tons of NOx per ozone season.
• For a unit that reports NOx mass emission data year-round, use this record to qualify as a
low mass emissions unit by demonstrating that the unit emits < 100 tons of NOx per year.
Data Projections
Projections may be used, as necessary, for Year 1, Year 2, or Year 3 (or for Ozone Season 1, 2,
or 3), when:
• Actual measured data (e.g., EDR reports) or reasonable estimates of actual emissions
derived from other sources (e.g., Part 60 monitoring data, process operating data, fuel
usage records, etc.) are not available (e.g., for a new unit);
• One or more of the past three years is not representative of current unit operation (e.g., if
controls were recently installed); or
• The owner or operator takes a federally enforceable permit restriction on unit operating
hours.
Historical Data
• If only historical data are being used to qualify, Year 1 would be three years before the
Qualification Data Year (i.e., the year of the LME application (see §75.19(a)(2)).
• If only projected data are being used, Year 1 would be the calendar year of the
Qualification Data Year (i.e., the year of the LME application).
• If only historical data are being used, Year 3 would be one year before the Qualification
Data Year or if only projected data were being used, Year 3 would be two years after the
Qualification Data Year (i.e., the year of the LME application).
• The appropriate calendar years for Ozone Seasons 1, 2, and 3 are determined in a similar
manner.

14.1 Monitoring Qual LME Data
September 17, 2014
LME Attainment Failure
• If a qualifying LME unit emits more than the allowable number of tons of SO2 or NOx in
a particular year or ozone season, the unit loses its LME status. Should this occur, the
owner or operator must install and certify monitoring systems in a timely manner, as
described in §75.19(b)(2).
• If LME status is lost, update the Monitoring Qualification Data record by
completing the end date. Also submit a Monitoring Method Data record indicating
changes in monitoring methodologies with the appropriate effective dates.
LME Emission Testing
• For information on emission testing of a group of identical LME units, refer to the UNIT
Default Test Summary Data record instructions in the QA Certification Data section
of the reporting instructions.
Updating the Monitoring Qual LME Data Record
This record is not designed to be updated from year to year. Rather, ongoing LME status is
demonstrated by the cumulative SO2 and NOx mass emissions reported in the hourly emissions
records. Changes to this data should only be necessary if the unit loses its LME status or needs
additional qualification records based on a change in program applicability or a change in
reporting frequency.

Description of Data
Report this record in conjunction with the Monitoring Qualification Data record to support
the qualifications of a peaking unit or gas-fired unit. For any year or ozone season in which a
unit qualifies as a peaking or gas-fired unit, submit a Monitoring Qual Percent Data record
documenting the capacity or fuel usage of the unit during a three year period. "Peaking unit" is
defined in 40 CFR 72.2 for an annual basis and is described in 40 CFR 75.74(c)(l 1) for an ozone
season basis. "Gas-fired" is defined in 40 CFR 72.2. Do this for any regulatory purpose (i.e.,
either for the selection of monitoring methodology, exemption from multi-load testing, or
frequency of on-going QA/QC activities).

14.2 Monitoring Qua! Percent Data
September 17. 2014
Specific Considerations
Qualifying Using Historical and/or Projected Data
• Provide three years of historical percent capacity factor or foe! usage information using
projected data as provided for in the definitions of gas-fired and peaking unit in §72.2.
• For a unit in a NOx mass emissions reduction, program reporting oil an ozone season-only
basis, provide ozone season capacity factor information for the period from May 1
through September 30 of each year. Yea* 1 should be the earliest year for which data are
reported (for example, if all historical data are being used. Year 1 would be three years
before the current calendar year or. if all projected data were being used. Year 1 would be
the current calendar year). Similarly, Year 3 should be the last year for which data are
reported i lor example, i f all historical data are being used. Year 5 would be one year
before the current calendar year or if all projected data were being used. Year 3 would be
two years after the current calendar year).
• Calculate the three year average annual capacity factor or percentage of the annual heat
input < HI J from the combustion ofga^eou* fuel, by averaging the percent capacity factor
(or percent of HI from gaseous fuel) for the three years of data provided. For example, if
a unit has operated for three years at 6.0 percent, 10.0 percent, and 12.0 percent annual
capacity factor, report each of these values as a Percentage Value element.

14.2 Monitoring Qual Percent Data
Peaking and Gas-Fired Unit Qualification
• If reporting to qualify both as a peaking unit and as a gas-fired unit, submit two
Monitoring Qualification Data records, one with QualificationTypeCode of GF
(gas-fired) and one with QualificationTypeCode of PK or SK. With each, report the
appropriate Monitoring Qual Percent Data record to demonstrate that the unit meets
the gas-fired or peaking unit criteria.
Qualifications for Gas-Fired Units
• In accordance with paragraph (3)(ii)(B) of the "gas-fired" definition in §72.2, 720 hours
of unit operating data may be provided to initially qualify as a gas-fired unit, if the
designated representative certifies that the pattern of fuel usage has permanently changed.
• A unit is classified as gas-fired as of the date on which the results of the 720 hour
demonstration are submitted to the Administrator (see paragraph (3)(iii) of "gas-fired"
definition). The 720 hour demonstration data qualifies a unit as gas-fired from the date
on which the results of the demonstration are submitted until the end of that same
calendar year.
• For the next year, actual, historical fuel usage data must be submitted from the previous
year (beginning with the date on which gas-fired qualification was first met) to verify that
fuel usage requirements were met for the first reporting year.
• For example, if qualified based on the 720 hour demonstration as of June 30, 2000, then,
in 2001, historical data must be submitted for the time interval from June 30, 2000
through December 31, 2000 (labeled as Year 1). In 2002, historical data would be
submitted for 2000 (labeled as Year 1) and 2001 (labeled as Year 2). In 2003, historical
data would be submitted for 2000, 2001, and 2002, labeled as Year 1, Year 2, and Year 3,
respectively (see Table 69, below).

** Initial qualification based on 720 hours of unit operating data
Initial and Subsequent Qualification
• It is possible a unit may initially qualify as a gas-fired or peaking unit by using historical
data or projected data. A combination of historical and projected data may be used.
However, to maintain peaking unit or gas-fired unit status, actual capacity factor or fuel
usage data for each subsequent year must be reported, Tims, if the basis for qualifying in
the first reporting year is on three years of projections, it is not possible to re-qualify in
the second reporting year based solely on projections. The qualifying data for the second
reporting year must include the actual capacity factor or fuel usage data from the first
reporting Near.
Loss of Status
• If. after evaluating the capacity factor or fuel usage data for a particular reporting year,
the unit no longer qualifies as a peaking or gas-fired unit, update the Monitoring Qual
Data record by reporting the appropriate End Date, to indicate that the peaking or gas-
fired unit status lias been lost.
• If a unit has previously qualified as a peaking or gas-fired unit but has lost that status and
re-establishing peaking or gas-fired status is wished, the unit may only re-qualify ba^ed
on three years of actual historical data. The use of projections is disallowed in such cases
(see §72.2, paragraph (4) of "gas-fired" definition and paragraph (3) of the "peaking unit"
definition).
Updating the Monitoring Qual Percent Data Record
For each unit, as applicable, add another Monitoring Qual Percent Data record at the
beginning of each calendar year (for year-round reporters) or at the start of the ozone season (for
ozone season-only reporters) to demonstrate on-going qualification, based on the previous year
(or ozone season) of historical data.

14.3 Monitoring Qual LEE Data
14.3 Monitoring Qual LEE Data
Figure 27
Monitoring Qual LEE Data XML Elements
Description of Data
For EGUs subject to the the MATS Rule, you are encouraged to report a Monitoring Qual
LEE Data record to provide initial and on-going evidence that an existing EGU (or a group of
EGUs sharing a common stack) qualifies as a low-emitter of Hg or HC1 under 40 CFR
63.10005(h). Note, however, that for HC1, this record applies only to coal-fired, petroleum coke-
fired, and IGCC EGUs.
(Note: For Hg, use of the LEE methodology is restricted to existing EGUs and is prohibited for
scrubbed units with main stack and bypass stack configurations). For HC1, the LEE option is
available for both new and existing EGUs).
For an EGU with a single unit-single stack configuration, the LEE methodology may be used if it
is demonstrated either that:
• The unit's potential to emit is less than 29.0 lb of Hg per year; or
• The unit's Hg emission rate is less than 10% of the applicable emission standard in Table
2 of 40 CFR Part 63, Subpart UUUUU.
A candidate EGU must undergo a 30 operating day demonstration test using EPA Method 30B
(for Hg concentration) together with other measured parameters to show that the unit qualifies as
a LEE. To retain LEE status, the demonstration test must be repeated annually.
For a group of candidate units that share a common stack, you may either perform the 30
operating day demonstration test on each individual unit or test at the common stack.
Monitoring Plan Reporting Instructions — Page 154
Environmental Protection Agency
-------
14.3 Monitoring Qual LEE Data
September 17, 2014
• If the common stack testing option is chosen, the individual units sharing the stack will
qualify as LEEs if:
— The average Hg emission rate from the test is < 10% of the applicable emission
standard; or
— The average Hg emission rate from the test meets the applicable emission standard
and the calculated annual Hg mass emissions from the group of units do not exceed
29.0 lb times the number of units sharing the stack.
• If the group of units sharing the stack qualifies for LEE status, report a Monitoring
Qual LEE Data record for the common stack.
For a candidate EGU with a multiple stack or duct exhaust configuration (excluding scrubbed
units with a main stack and bypass stack), you must separately test each stack or duct. The unit
qualifies for LEE status if:
• The Hg emission rate is < 10% of the applicable Hg emission standard at all of the stacks
or ducts; or
• The sum of the calculated annual Hg mass emissions from all of the stacks or ducts does
not exceed 29.0 lb.
The LEE methodology for HC1 may be used if:performance test results show that the HC1
emissions are less than 50 percent of the applicable limit in Table 1 or Table 2 of Subpart
UUUUU for 3 consecutive years;
Dependencies for Monitoring Qual LEE Data
The Monitoring Qual LEE Data record is dependent on the Monitoring Qualification
Data record.
No other records are dependent upon the Monitoring Qual LEE Data record.
Monitoring Qual Hg LEE Data Elements
Instructions for completing each element of the Monitoring Qual Hg LEE Data section are
provided below:
Qualification Test Date
Element Name: QualificationTestDate
For Hg, report the end date (MMDDYYYY) of the demonstration test (i.e., either the initial LEE
qualifying test or the latest retest, as applicable) showing that the unit (or group of units sharing a
common stack) qualifies to use the LEE methodology.
For HC1, report the end date (MMDDYYYY) of the performance test that completes the 3 year
demonstration for LEE qualification.
Environmental Protection Agency

Element Name: ParameterCode
Report the appropriate Parameter code (HG or HCL) associated with the LEE qualification.
Qualification Test Type
Element Name: QualificationTestType
Indicate whether the LEE qualification test is the initial 30 operating day demonstration test or a
retest. Report "INITIAL" if it is the initial test and "RETEST" if it is a retest.
Potential Annual Hg Mass Emissions
Element Name: PotentialAnnualHgMassEmissions
If the unit (or group of units sharing a common stack) seeks to qualify for the LEE methodology
based on its potential annual Hg mass emissions, report the calculated annual emissions in
pounds (rounded off to one decimal place). Calculate the potential annual Hg mass emissions
according to 40 CFR 63.10005(h). Leave this field blank if LEE qualification for Hg is based on
emitting at less than 10% of the applicable emission standard.
Applicable Emission Standard
Element Name: ApplicableEmissionStandard
If the unit (or group of units sharing a common stack) seeks to qualify as a LEE by emitting at
less than 10% of the applicable Hg emission standard, specify the numerical value of that
standard. This field should be reported in standard notation and not scientific notation. Leave
this field blank if LEE qualification is based on the potential annual Hg mass emissions.
Units of Standard
Element Name: UnitsofStandard
If the unit (or group of units sharing a common stack) seeks to qualify for LEE by emitting at
less than 10% of the applicable Hg emission standard or less than 50% of the applicable HC1
emission standard, specify the units of measure of that standard. Report "LBTBTU" if the units
of the standard are lb/TBtu, "LBMBTU" if the units of the standard are lb/mmBtu, "LBMWH" if
the units of the standard are lb/MWh, and "LBGWH" if the units of the standard are lb/GWh.
Leave this field blank if Hg LEE qualification is based on the potential annual Hg mass
emissions.
Percentage of Emission Standard
Element Name: PercentageOfEmissionStandard
If the unit (or group of units sharing a common stack) qualifies for LEE based on emitting at less
than 10%) of the applicable Hg emission standard or less than 50% of the applicable HC1
emission standard, report the results of the demonstration test (or retest) as a percentage of the
standard, rounded to one decimal place. Leave this field blank if Hg LEE qualification is based
on the potential annual Hg mass emissions.

September 17, 2014
Specific Considerations
Loss of LEE Status
• If the annual retest of a LEE (or group of LEEs sharing a common stack) shows that the
unit (or group of units) no longer qualifies for Hg LEE status, the owner or operator must
install and certify Hg CEMS or sorbent trap monitoring system(s) within 6 months (see
section 63.10006(b)(2) of Subpart UUUUU).
• If the triennial (i.e., once every 3 years) HC1 retest of a LEE shows that the unit no longer
qualifies for HC1 LEE status, the owner or operator must conduct quarterly emissions
testing for HC1.
• If LEE status is lost, update the Monitoring Qualification Data record by completing
the end date. Also submit Monitoring Method Data or supplemental mats
compliance Method Data records (as applicable), indicating changes in monitoring
methodologies with the appropriate effective dates (see Sections 6.0 and 6.1, above).
Note that reporting of supplemental mats compliance Method Data records is
optional.
Updating the Monitoring Qual LEE Data Record
For a unit (or group of units sharing a common stack) that initially qualifies for LEE status, the
Monitoring Qual Hg LEE Data record must be updated annually (for Hg) or every three
years (for HC1), based on the results of each required retest.
