                          Reporting Instructions for
                           MATS Compliance Reports 

Introduction

About This Document

The Emissions Collection and Monitoring Plan System (ECMPS), requires data to be submitted to the EPA through a "Client Tool", using extensible-markup language (XML) format.  An XML file contains certain data elements, which are defined in one or more "schemas".  

The purpose of these reporting instructions is to enable owners and operators of affected coal-fired and oil-fired electricity generating units (EGUs) to document compliance with emission limits under the Mercury and Air Toxics Standards (MATS) rule (40 CFR Part 63, Subpart UUUUU).  

An XML schema is typically made up of a root element (which is the base of the schema), simple elements, and complex elements.  A simple element is a single piece of data.  A complex element is a group of simple elements that are logically grouped together.

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 or parents 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 illustrates the relationships between the root element and the complex and simple elements for the MATS compliance report schema.

This document provides instructions on how to report the required data using this data structure.  A separate section is provided for each complex element, its dependencies, and its simple elements.  In addition, the document discusses specific considerations that apply when reporting data for particular types of monitoring configurations.

About MATS Compliance Data

Compliance data are required for each EGU affected by MATS.  The MATS compliance report data file will include the results of any performance stack test that is used to demonstrate compliance with the MATS standards as well as any 30- (or in some cases 90-) boiler operating day rolling averages that must be reported for MATS compliance.  The rolling averages are based on data from continuous emission monitoring systems (CEMS), sorbent trap monitoring systems, or continuous parametric monitoring systems (CPMS).  If applicable, the MATS compliance report data file must also include any 30- or 90-group boiler operating day rolling averages reported for units included in an averaging plan.  

The MATS Compliance report data file will also include unit information for each affected EGU at the facility.  Specifically, the date of the last tune-up, fuel usage during the reporting period, malfunction information, and emergency bypass information must be reported.

A MATS Compliance report data file covering all of the MATS-affected units at a given facility must be submitted for each calendar quarter.  Each report must be submitted no later than 60 days after the end of the calendar quarter, and must be accompanied by the applicable reference method data described in sections 17 through 30 of Appendix E to Subpart UUUUU, pertaining to performance stack tests that were completed during the calendar quarter..  
 
Rounding Conventions for Reporting Emissions Values

Each emissions value that is reported must be rounded to a specified precision.  The appropriate precision for compliance averages is based on the precision of the emission limit specified in the MATS rule.  

All of the emission limits in Tables 1 and 2 of MATS are expressed in scientific notation, rounded to one decimal place.  In view of this, for the purposes of compliance demonstrations using MATS compliance report records, all stack test results and rolling average emission rates must be reported in scientific notation with one leading non-zero integer, rounded off to this same precision, i.e., to one decimal place with no spaces in-between characters.  Use the standard arithmetic rounding convention, where numbers five through nine round to the next highest number and numbers four or below round downward.  For example, if the average emission rate from a stack test is 0.0185 lb/mmBtu, you would round off to 0.019 lb/mmBtu and then report it in equivalent scientific notation as 1.9E-2 in the MATS compliance report data file.   

Remove "Compliance Indicator" from the schema below.  Also, add "Facility Name" immediately below "ORIS Code".

[2]The data elements in this schema correspond to sections 8.1 through 8.3 of Appendix E to Subpart UUUUU.

Description of Data

The Averaging group configuration record is reported only when you have elected to use emissions averaging under §63.10009.  This record requires an averaging group ID to be assigned and identifies the parameter to be averaged and the units and/or common stacks that are included in the averaging plan.  In each quarterly report, you must submit one Averaging group configuration record for each unit or common stack in the averaging plan.

If you elect to average individual HAP metals, you must submit a separate Averaging group configuration record for each one. 

Use the following instructions to report each data element of the Averaging group configuration record:

Parameter
Element Name: Parameter

Select the code for the parameter to be averaged from the list in Table 1, below, and report this value.

Averaging Group ID
Element Name: AveragingGroupID

Assign an ID number to the averaging group.  The ID must begin with the prefix "GP", followed by one to four alphanumeric characters (e.g., GP1, GP123A).

Unit ID
Element Name: UnitID

For each EGU in the averaging group that is tested or monitored at the unit level, report the Unit ID.  If there is an electronic monitoring plan in ECMPS for the unit, report the Unit ID exactly as it appears in the monitoring plan.  Otherwise, report the ID assigned to the unit by the facility.

Common Stack ID
Element Name: CommonStackID

For each common stack in the averaging group that is tested or monitored at the common stack level, report the common stack ID.  If there is an electronic monitoring plan in ECMPS for the common stack, report the common stack ID exactly as it appears in the monitoring plan.
 Otherwise, report the ID assigned to the stack by the facility, prefaced by the letters "CS" (e.g., if the common stack is known as "Stack #7", report "CS7" as the stack ID).

[________________________________]
[3]The data elements in this schema correspond to sections 3.1 through 3.14 of Appendix E to Subpart UUUUU.

Add "Test Number" to the schema above, after "Test Location ID"

Description of Data
Performance Test Summary Data records (see Figure 4) are reported for all performance stack tests that are used to demonstrate compliance with an emission limitation, i.e., required quarterly or annual stack tests and/or LEE qualification tests (including 30 boiler operating day LEE tests for Hg).  
Submit one Performance Test Summary Data record for each performance stack test that is completed during the calendar quarter and is used to demonstrate compliance with a MATS emission limit, including any LEE qualification tests and/or annual filterable PM performance tests that are used in conjunction with a PM CPMS.  

If quarterly Method 29 tests are used to demonstrate compliance with individual HAP metals standards, submit a separate Performance Test Summary Data record for each HAP metal.  The data in the Test Location, Test Number, Begin and End Dates/Times, Timing of Test, and Test Method Code fields will be the same in all of these records.  The data in the Parameter, Emission Limit, and Emission Limit Units of Measure fields will be specific to each HAP metal.

If the results of a particular stack test are used as part of an emissions averaging plan, you must submit the test results in a Performance Test Summary Data record, but compliance with the weighted average emission rate (WAER) for the emissions averaging group is demonstrated using the Compliance averages records.  

Use the following instructions to report each element of the Performance Test Summary Data record.
Parameter
Element Name: Parameter
Report the code that indicates the parameter from the list in Table 1, above.  Note:  Parameter "SO2" is not applicable.  When SO2 serves as a surrogate for HCl, continuous monitoring is required; stack testing is not an available compliance option.
Test Location ID
Element Name: TestLocationID
Report the Unit or Stack ID that represents the location at which the performance test was done.  If there is an electronic monitoring plan in ECMPS for the unit or stack, the Unit or Stack ID reported here must be the same as the ID in the monitoring plan.   Otherwise, report the ID assigned by the facility to the unit or stack at which the performance test was done.  If the unit or stack is in an averaging plan, the Unit or Stack ID must exactly match the unit or stack ID in the Averaging group configuration record.
Test Number
Element Name: TestNumber

You must assign a unique test number to each performance stack test.  This number must exactly match the one assigned to the test in the supplementary report that provides the essential data elements from Appendix F of Subpart UUUUU for the reference method(s) used in the performance test.

Begin Date 
Element Name: BeginDate 
Report the begin date of the first run in the test (MMDDYYYY). 
Begin Hour
Element Name: BeginHour 
Report the begin hour of the first run in the test (00-23). 
End Date 
Element Name: EndDate 
Report the end date of the last run in the test (MMDDYYYY). 
End Hour
Element Name: EndHour 
Report the end hour of the last run in the test (00-23). 
Timing of Test
Element Name: TimingOfTest

Report "1" if the test was performed on-schedule, according to §63.10006(f) of the MATS rule.  Report "0" if the test was performed late. 

Used In Averaging Plan 
Element Name: UsedInAveragingPlan
Report "1" if the test was performed on a unit (or stack) that is included in an emissions averaging plan, and "0" if the test was performed on a unit (or stack) that is not included in an emissions averaging plan.  If a 1 is reported, the test results presented in the Performance Test Summary Data record are not used directly to demonstrate compliance but rather are used in conjunction with stack test results and/or hourly CEMS (or sorbent trap system) emission rates from other units to determine the 30- or 90-day weighted average emission rates (WAERs) for the group of units.  The calculated 30- or 90-day rolling averages are reported in the Compliance averages record.
Averaging Group ID
Element Name: AveragingGroupID

If the results of this performance test are to be included in an emissions averaging plan along   with stack test results and/or hourly CEMS (or sorbent trap) emission rates from other affected EGUs report the Group ID number that was established in the Averaging group configuration record.   

Test Method Code
Element Name: TestMethodCode
Report the reference method used to determine the pollutant concentration, using the codes in Table 2, below. 
Emissions Limit
Element Name: EmissionsLimit

Average Emission Rate
Element Name: AverageEmissionRate
For quarterly and annual stack tests, determine the average pollutant emission rate for the 3 (or more) test runs by averaging the individual Emission Values reported in the Performance Test Run Data records.  Report the average pollutant emission rate in this field, in the units of measure of specified in the Emissions Limit Units of Measure field.  Express the emission rate in scientific notation with one leading non-zero digit and one decimal place (e.g., 2.5E-1).
For 30-boiler operating day Hg LEE tests, proceed as follows. 
 For each pair of sorbent traps used (i.e., for each data collection period), determine the Hg concentration and the average value of each parameter that is used to convert Hg concentration to units of the emission standard (i.e., CO2 or O2 concentration, stack gas flow rate, electrical load, or moisture content, as applicable).  The average parameter values for each data collection period are reported in the Conversion Parameters records.
 Then, determine the overall average values of Hg concentration and each parameter for the 30-day test, by taking the arithmetic average of all of the average parameter values from the individual data collection periods.  
 Finally, use the overall average value of each parameter together with the overall average Hg concentration to determine the average Hg emission rate for the 30-day test, and report the result in this field.
LEE Indicator
Element Name: LEEIndicator

If this stack test is used to establish (or re-establish) LEE status, report "1" in this field; otherwise, report "0".  Note: For pollutants other than Hg, 3 years of stack test data are required to establish LEE status.  If the requisite 3-years of data have not yet been accumulated, report "0" for this test.

Description of Data

Conversion Parameters records are used to report values of the parameters that are required to convert the pollutant concentration values measured by the reference method to the units of the MATS emissions standard.  Conversion parameters may include CO2 or O2 concentration, stack gas flow rate, moisture content, or electrical load, as applicable.  

For each test run, report one Conversion Parameters record for each parameter that is used to convert the concentration to the units of the standard.  The number of Conversion Parameters records that you must report depends on the emission rate equation used for the conversion, which, in turn, depends on whether you have elected to comply with a heat input-based standard or an electrical output-based standard. 

Use the following instructions to report each element of the Conversion Parameters record.

Value
Element Name:  Value

For quarterly and annual stack tests, and for triennial LEE tests, report the numerical value of the conversion parameter for the test run.  

For 30-boiler operating day Hg LEE tests using Method 30B, report the average value of the parameter for the data collection period with a particular pair of sorbent traps.  

Note: The MATS Rule requires the overall average diluent gas concentration, stack gas flow rate, stack gas moisture content, and electrical load values for the entire 30- boiler operating day test period to be used together with the overall average Hg concentration for the entire test period (as reported in the Performance Test Summary Data record) to calculate the average Hg emission rate for the LEE test (see §63.1005(h)(3)(ii) and (iii)).  To obtain the overall average value of a particular conversion parameter for the 30- boiler operating day test, you must take the arithmetic average of the average values of that parameter for the individual data collection periods.

Description of Data

The QA Parameters record is used to report the results of various quality assurance activities that are used to validate the reference method used during the performance test run (or, if applicable, for Hg LEE tests), during the data collection period with a particular pair of sorbent traps.

Use the following instructions to report each element of the QA Parameters record.

Parameter Type
Element Name:  ParameterType

Identify the applicable QA parameter code(s) from Table 9 below for the reference method used to measure the pollutant concentration during the performance test run (or data collection period).  A separate QA Parameters record must be reported for each QA parameter specified in Table 9 that applies to the reference method.   

For Method 30B tests, report leak check results using parameter codes LEAKA and LEAKB and breakthrough results using parameter codes BRKA and BRKB when the test results are based on both sorbent trap system trains (A and B).  However, when Method 30B test results are based on a single sorbent trap, report leak check and breakthrough results using parameter codes LEAK and BRK, respectively (see section 12.8.3 of Performance Specification 12B in Part 60, Appendix B).

________________

[7] The data elements in this schema correspond to sections 4.1 through 4.3 of Appendix E to Subpart UUUUU.

Description of Data

For MATS affected units, the Operating Limit Data record is only used to report the operating limit established during annual filterable particulate matter performance testing for sources that use a PM CMPS.  Do not report an Operating Limit Data record for any other performance tests. 

Use the following instructions to report each element of the Operating Limit Data record:

Parameter Type
Element Name:  ParameterType

Report a parameter type of "PMCPMS".

Operating Limit
Element Name:  OperatingLimit

Report the operating limit, i.e., either the highest one-hour average PM CPMS output value recorded during the performance test or the extrapolated PM CPMS output value corresponding to 75 percent of the applicable PM emissions limit, in accordance with §63.10023(b) and Table 6 of Subpart UUUUU.

Units of Measure
Element Name: UnitsofMeasure

Report the units of measure of the PM CPMS operating limit.  If the operating limit is in units of milliamps, report MA; if it is in units of particulate concentration, report PMC, or if it is in some other units of measure (raw data signal), report OTHER.

            Compliance averages XML Elements[8]

                                       

____________________

[8] The data elements in this schema correspond to sections 9.1 through 9.8 of Appendix E to Subpart UUUUU.

Description of Data

Compliance Averages records are used to report the 30- (or 90-) boiler operating day rolling averages that are used to demonstrate compliance with MATS limits based on CEMS, sorbent trap system, or PM CPMS data.  These records are also used to report the 30- or 90-group boiler operating day rolling averages for units and common stacks included in an averaging plan. 

 For an EGU that is not included in an averaging plan, if emissions are monitored and reported at the unit level, a new 30- (or 90-) boiler operating day rolling average emission rate for each applicable pollutant (or, if applicable, a new 30- boiler operating day rolling average PM CMPS value) is calculated and reported in a Compliance averages record, for each boiler operating day in the calendar quarter. Exclude boiler operating days on which   fuel is combusted only during startup and/or shutdown, unless sorbent trap monitoring systems are used and all of the emissions data are included in the compliance determinations.  

 When emissions from multiple EGUs are monitored and reported at a common stack that is not in an averaging plan, a new 30- (or 90-) boiler operating day rolling average emission rate for each applicable pollutant (or, if applicable, a new 30- boiler operating day rolling average PM CMPS value) is calculated and reported in a Compliance averages record, for each day in the calendar quarter on which any unit that shares the common stack combusts any fuel.  Exclude boiler operating days on which   fuel is combusted only during startup and/or shutdown, unless sorbent trap monitoring systems are used and all of the emissions data are included in the compliance determinations.  

 For EGUs that are part of an emissions averaging plan, a new 30- or 90-group boiler operating day weighted emissions average emission rate (WAER) is calculated for each applicable pollutant and reported in a Compliance averages record, for each day in the calendar quarter on which any unit in the averaging plan combusts any fuel.  Exclude boiler operating days on which   fuel is combusted only during startup and/or shutdown, unless sorbent trap monitoring systems are used and all of the emissions data are included in the compliance determinations.    

 Do not report a Compliance averages record for any pollutant (or CPMS value) for any day in the calendar quarter on which no fuel is combusted in the affected unit (or units), or for operating days on which fuel is combusted only during startup and/or shutdown, unless sorbent trap monitoring systems are used and all of the emissions data are included in the compliance determinations.  

 If, for a particular pollutant, quarterly stack test data are used as part of an emissions averaging plan, you must report those stack test results using Performance Test Summary Data and Performance Test Run Data records, as described in sections 3.0 and 3.1, above.  Then you must include the stack test results in the calculation of each  30- or 90-operating day weighted average emission rate (WAER) for the averaging group, as described in §63.10009, and report the WAER in a Compliance averages record.  See Examples 1 and 2, below:

Example 1: Suppose that a facility includes three MATS-affected units, and emissions are measured at the unit level using CEMS for SO2, PM and Hg.  The units are designed to combust coal with a GCV >= 8,300 Btu/lb.  The source decides to implement a 90 group boiler operating day averaging plan for Hg that includes all three units, but will not use emissions averaging for SO2 or PM.  

For each unit, the source would have to report one Compliance averages record for SO2 and one Compliance averages record for PM for each boiler operating day in the calendar quarter on which a new 30 day rolling average emission rate is calculated.  For Hg, the source would report a Compliance averages record for each group boiler operating day in the calendar quarter on which a new 90-group boiler operating day weighted average emision rate is calculated for the group of units.    

Example 2:  Suppose that a facility has three affected coal-fired units and elects to monitor HCl emissions using a CEMS on two of the units and to perform quarterly HCl stack testing on the third unit.  All three units are included in an averaging plan for HCl.  In the 1[st] and 2[nd] calendar quarters, the required quarterly HCl stack tests for the third unit are performed on February 15[th] and May 1[st], respectively.  

The source must report a Compliance averages record for each group boiler operating day in the calendar quarter on which a new 30-group boiler operating day weighted average HCl emission rate is calculated for the group of units.  The weighted average emission rates are calculated as follows:

 From the beginning of the calendar quarter through May 1[st], the results of the February 15[th] stack test of the third unit (which were reported using PERFORMANCE TEST SUMMARY DATA and PERFORMANCE TEST RUN DATA records) are used together with hourly average CEMS emission rates from the other two units to calculate the WAER for the group of units.  

 Then, for the remainder of the calendar quarter, the results of the May 1[st] stack test of the third unit (which are reported using PERFORMANCE TEST SUMMARY DATA and PERFORMANCE TEST RUN DATA records) are used together with hourly average CEMS emission rates from the other two units to calculate the WAER.    

Use the following instructions for reporting each element of the Compliance averages record.

Unit ID
Element Name: UnitID

If a particular unit is not included in an averaging plan, and emissions (or, if applicable, PM CPMS values) are monitored and reported at the unit level, report the Unit ID in this field, exactly as it appears in the electronic monitoring plan for the unit.  Otherwise, leave this field blank.

Common Stack ID
Element Name: CommonStackID

If emissions (or, if applicable, PM CPMS values) are monitored and reported at a common stack and the common stack is not included in an averaging plan, report the Common Stack ID in this field, exactly as it appears in the electronic monitoring plan for the unit.  Otherwise, leave this field blank.

Averaging Group ID
Element Name: AveragingGroupID

If emissions averaging is being used for a particular parameter, report the Group ID that was established in the Averaging group configuration record.  If emissions averaging is not used for the parameter, leave this field blank.

Parameter
Element Name: Parameter
Report the code that indicates the applicable parameter from Table 1, above.  Note: If a PM CPMS is used for the compliance demonstration, report a parameter code of "PMCPMS" in this field to represent the raw PM CPMS response values.
Date 
Element Name: Date 
Report the date (MMDDYYYY) for the boiler operating day for which an emissions average is being reported.  
Average Type
Element Name: AverageType 
Report the average type from the list below.  Note that compliance for MATS is demonstrated using 30-day averages except for Hg emissions where the owner or operator may demonstrate compliance on a 90- group boiler operating day basis.

For units or common stacks that are not included in an averaging plan, report the 30- (or 90-) boiler operating day rolling average determined for the boiler operating day in the same units of measure that are reported in the Units of Measure field.
If the data is being reported for an emissions averaging group, report the rolling 30- or 90-"group boiler operating day" weighted average emission rate (WAER) for the group boiler operating day in the same units of measure that are reported in the Units of Measure field.  
Comment 
Element Name: Comment 
Report any comments regarding the emissions average data.

                            Special Considerations
For units in an averaging plan, the 30- or 90-boiler operating day WAER values may be based on CEMS data, sorbent trap monitoring system data, stack test results, or, in some cases, a combination of these.  Use Equation 2a, 2b, 3a, or 3b in §63.10009(b) (as applicable) to calculate the WAERs.  When using these equations, note the following considerations for each EGU in the averaging group:

 When CEMS (or sorbent trap system) data are to be included in the calculation of the 30- (or 90-) group boiler operating day WAERs, you must use all valid hourly average pollutant emission rates and the corresponding hourly heat input (mmBtu), electrical generation (MWh), or steam generation (lb) values (as applicable) recorded during each 30- (or 90-) day group boiler operating day period.  Each 30- (or 90) day average must exclude Part 75 bias adjusted data and/or substitute data, as well as any hourly averages recorded during periods of startup or shutdown, as defined by the MATS rule, must be excluded, except as follows:
      
 If you monitor Hg emissions with a sorbent trap monitoring system, you may opt to include startup and shutdown emissions in your compliance determinations; and
 For monitored common stacks, startup and shutdown emissions must be included in compliance determinations when at least one unit other than the unit(s) starting up or shutting down is in normal, stable operation.    
 
 If stack test data are to be included in the WAER calculations, you must use the average pollutant emission rate from the most recent test together with the cumulative heat input, electrical output, or steam generation values (as applicable) for each 30- or 90- group boiler operating day period.
      
 If you elect to use steam generation instead of heat input or electrical generation to calculate the WAER, you must use a conversion factor (i.e., mmBtu per lb of steam generated or MWh per lb of steam generated), obtained from the most recent compliance or emission test.

Description of Data

Report one Unit Information record for each affected unit at the facility.  You must report the unit type, and, as applicable, the date of the last boiler tune-up and burner inspection.

Elements that depend on the Unit Information record. 

The following complex element is dependent upon the Unit Information record.  This element cannot be submitted unless a Unit Information record is included in the data file:

 Fuel usage data
 malfunction information

Use the following instructions to complete each element of the Unit Information record:

Unit ID
Element Name: UnitID

Report the ID of the affected unit.  If there is an electronic monitoring plan in place in ECMPS for the unit, report the Unit ID exactly as it appears in the monitoring plan.  

Last Tune-up Date
Element Name:  LastTuneupDate

Report the completion date of the most recent performance tune-up done to comply with the requirements in §63.10021(e).  

Emergency Bypass Information
Element Name:EmergencyBypassInformation

In general, an existing EGU may not use the LEE compliance option if: 

 It is coal-fired, petroleum coke-fired, or is an IGCC; and 

 Is equipped with a main stack and bypass stack (or duct) that allows the effluent to bypass a control device.  

However, there is an exception to this.  Section 63.10000(c)(1)(i)(C)(2) allows the LEE option to be used for such a unit if: 

 The EGU initially qualifies for LEE status; 

 The required LEE retests are performed (e.g., annually for Hg); 

 The control device is bypassed only during emergency periods totaling no more than 2 percent of the EGU's annual operating hours, and clean fuels are burned to the maximum extent practicable during the emergency periods; and 

 Emergency bypass information is reported annually.  

If you choose to implement the alternative LEE compliance option in §63.10000(c)(1)(i)(C)(2), use the following instructions to report emergency bypass information:  

(Note: Bypass hours in which only clean fuel is combusted are exempted from this reporting requirement).

In the compliance report for the fourth quarter of each calendar year, use a text field to report the following emergency bypass information: 

 Report the total number of emergency bypass hours for the calendar year as a percentage of the EGU's annual operating hours.
 Briefly describe each emergency event, including the cause and corrective actions taken. 
 Explain how clean fuels were burned to the maximum extent practicable. 
 Provide an estimate of the emissions released during the bypass event(s).  
 Show how this emissions estimate, taken together with the results of the most recent LEE retest, demonstrates that the EGU continues to qualify as a LEE, or that LEE status has been lost.  	
 If there were no emergency bypass events in the year, include a statement to that effect.

Elements that depend on the unit information record  

The following complex elements are dependent on the unit information record, in a parent-child relationship. These complex elements cannot be submitted unless a unit information record is included in the data file.

Note that EPA allows the use of non-waste, non-hazardous secondary fuels if certain criteria under 40 CFR 241.3 are met.  Except for the materials listed in (a) through (d), below, whether or not a particular material qualifies as a non-waste, non-hazardous fuel type is determined by EPA through the petition process.  

According to 40 CFR Part 241.4, the following non-hazardous secondary materials are not considered to be solid waste when used as fuel in a combustion unit:

   (a) Scrap tires that are not discarded and are managed under the oversight of established tire collection programs, including tires removed from vehicles and off-specification tires.
   (b) Resinated wood.
   (c) Coal refuse that has been recovered from legacy piles and processed in the same manner as currently-generated coal refuse.
   (d) Dewatered pulp and paper sludge that are not discarded and are generated and burned on-site at pulp and paper mills that burn a significant portion of such materials, provided that the dewatered residuals are managed in a manner that preserves their meaningful heating values.
If any of these non-waste, non-hazardous fuel is combusted during the month, or if another secondary fuel that qualifies as a non-waste, non-hazardous fuel report the fuel type using the appropriate code in Table 15.

[12] The data elements in this schema correspond to sections 13.1 through 13.5 of Appendix E to Subpart UUUUU.

Description of Data

If there were any deviations during the reporting period, submit Deviations records to represent them.

If there were no deviations, report a single Deviations record and provide information only in the Unit, Stack, or Group ID and Comment fields.  Leave the other fields blank.

Use the following instructions to report the applicable elements of each Deviations record.

Unit ID 
Element Name:  UnitID	

If the deviation is being reported for an individual EGU that has either exceeded an emission limit (or operating limit), or that has not met a work practice standard, testing or monitoring requirement, report the corresponding Unit ID exactly as it appears in the electronic monitoring plan for the unit.  If there is no electronic monitoring plan in ECMPS for the unit, report the ID assigned to the unit by the facility.

Common Stack ID
Element Name: CommonStackID

If the deviation is being reported for a common stack at which an emission limit (or operating limit) has been exceeded, or at which a testing or monitoring requirement has not been met, report the Common Stack ID exactly as it appears in the electronic monitoring plan for the unit.  If there is no electronic monitoring plan in ECMPS for the unit, report the ID assigned to the stack by the facility, prefaced by the letters "CS" (e.g., if the facility-assigned stack ID is "7", report "CS7" as the common stack ID).

Averaging Group ID
Element Name: AveragingGroupID

If the deviation is being reported for the exceeding an emission limit for a particular parameter where emissions averaging is being used to demonstrate compliance with that parameter, report the Averaging Group ID that was established in the Averaging group configuration record.  

Nature of the Deviation

Description of the Deviation
Element Name: DescriptionoftheDeviation

Provide a detailed description of the deviation in this text field, as follows:

1.  If the deviation is an emission limit or operating limit exceedance (code ELEX or OLEX), report:

 The parameter (e.g., Hg, HCl, PM, milliamps);

 The limit that was exceeded;

 The date of the emission test that exceeded the limit (if applicable);

 The beginning and ending dates of the 30- or 90- boiler operating day rolling average that exceeded the limit (if applicable).  If there were multiple exceedances, you may itemize the beginning and ending dates of each one in this data field; it is not necessary to report multiple Deviations records.

2.  If the deviation is a failure to meet a work practice standard, testing requirement, monitoring requirement, or other requirement (codes WPNM, TRNM, MRNM, and ORNM), specify which standard or requirement was not met.  In addition:

 For any unmonitored bypass stack usage during the quarter, indicate the total number of hours that the bypass stack was used.

 For any failure(s) to collect required monitoring data, report:

 The monitored parameter;
 The total source operating time (hours) in the quarter;
 The number of hours of monitoring system downtime due to:

 Monitoring system malfunctions;
 Out-of-control periods;
 Non-monitoring equipment malfunctions;
 QA/QC activities (e.g., calibrations, performance audits);
 Routine maintenance;
 Other known causes; and
 Unknown causes.

   (Note:  Monitoring system outages for required QA/QC activities and/or routine maintenance must be reported, but are not considered to be deviations).

 For an emission test that was due within the reporting quarter but was not performed, specify the parameter (e.g., HCl, PM, etc.) and the test deadline, and state that the test was not done as required.

 For a late emission test that was performed during the reporting quarter (as indicated by a "Timing of Test" flag of "0" in section 3.0 of these Instructions), specify the test parameter, the test deadline, and indicate how many days elapsed between the test deadline and the test completion date.

3.  Briefly describe any follow-up or corrective actions taken in response to the deviation.

Comment
Element Name: Comment

You may opt to provide any additional information related to the deviation in this field.

If there were no deviations in the reporting period, make a statement to that effect in this data field.
