1.0 I NTRODUCTION 

### : E MISSIONS

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 i n the XML schema. (Note: More information about the ECMPS XML Schemas can be found in the XML Schema Description Documents.)

The purpose of the reporting instructions is to provide the necessary information for owners and operators to meet the reporting requirements for sources affected by:

1) The Acid Rain Program (ARP); 2) The Clean Air Interstate Rule (CAIR); and 3) Other programs required to report data using these XML schemas.

These instructions explain how to report the required data for the applicable regulations. Owners and operators of units should refer to the applicable regulations for information about what data are required to be reported.

The Emissions 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 emissions root element and the complex elements.

This document provides instructions on how the required data should be reported using this data structure. A separate section is provided for each complex element, its dependencies, and its simple elements. In addition, there are " specific considerations " that apply to particular types of monitoring plan configurations.

About Emissions Data

Emissions data are hourly values for measured parameters, calculated hourly emissions values, instrument calibration data, and aggregated summary data. An emissions file contains one

Environmental Protection Agency Emissions Reporting Instructions

-- Page 1March 07, 2012 September 19, 2012 1.0 Introduction: Emissions

calendar quarte r of hourly and aggregate emissions measurements for a specified unit or group of related units, including stacks and pipes.

Each unit that is required to submit emissions data for a particular calendar quarter must be included in one and only one emissions file for that quarter. Each emissions file should contain all relevant operating, daily quality assurance, and emissions data for all units, common stacks, multiple stacks, or common pipes that were in a common monitoring configuration for any part

of the quarter.

You must submit an emissions file for each quarter or, for ozone season only reporters, for the second and third calendar quarters of each year.

Rounding Conventions for Reporting Emissions Values

Each emissions value that is reported must be rounded to a specified number of decimal places. The appropriate number of decimal places is based on the parameter, fuel type, and/or record type. Because some fields were designed to be generic and support reporting data for different

parameters, it is not always appropriate to report values to the number of decimal places in the XML format. The appropriate precision for each parameter (and fuel type) can be found in the instructions under each record type.

Use the standard arithmetic rou nding convention where numbers five through nine round to the next highest number in the previous decimal position to the left.

For example, when reporting SO2C, NOXC, CO2C, O2C, or H2O in the M ONITOR H OURLY
V ALUE D ATA (MHV) record, round these value s to the near est 0.1 ppm or 0.1 percent (as applicable). When reporting FLOW, the last significant digit in the reported flow rate values is in the thousands place; fill in zeros in the hundreds, tens, and unit columns (e.g., round 15, 922,855 scfh to 15,923,000 scfh). When reporting NOXR in the D ERIVED H OURLY V ALUE D ATA (DHV) record, round the NO

x emission rate to three decimal places.

Use of Rounded and Unrounded Values in Emissions Calculations

When performing calculations using any value that is reported in the XML, use the value as it is reported. In other words, use the rounded value in the calculation. However, any value that is calculated in an intermediate equation but is not reported should not be rounded before using it in a subsequent equation.

For exa mple, to calculate the bias -adjusted SO 2 concentration, multiply the UnadjustedHourlyValue in the SO2C MHV record (which has been reported as a value rounded to one decimal place) by the bias adjustment factor (which has been reported in the RATA as a

valu e rounded to three decimal places), and round the result to one decimal place before reporting this value as the AdjustedHourlyValue in the MHV record. To calculate the hourly

SO 2 mass rate in lb/hr using formula F -1, use the AdjustedHourlyValue in the SO 2C MHV record (which has been rounded to one decimal place) and AdjustedHourlyValue in the FLOW MHV record (which has been rounded to the nearest thousand) in the equation, and round the result to one decimal place before reporting this value as the AdjustedHourlyValue in the SO2 DHV record. When calculating quarterly SO 2 emissions in tons, first multiply the

Emissi ons Reporting Instructions

-- Page 2 Environmental Protection Agency1.0 Introduction: Emissions March 07, 2012September 19, 2012

AdjustedHourlyValue in the SO2 DHV record (which has been rounded to one decimal place) by the OperatingTime (which has been rounded to two decimal places) for every hour. Sum these unrounded products, then divide this unrounded sum by 2 ,000. Finally, round the result to one decimal place before reporting the quarterly emissions value in S UMMARY V ALUE D ATA record.

S UMMARY V ALUE D ATA XML Elements

S UMMARY V ALUE D ATA Overview

Description of Data

The S UMMARY V ALUE D ATA record s are used to report aggregated values for the parameter s included in the emissions submission file and cumulative values for the year and/or ozone

sea son. Summary values are reported by monitoring location and parameter on the basis of the current reporting period, year

- to

- date, and, if relevant, ozone season- to -date sums (or averages)

. For each monitoring location in the file, r eport a S UMMARY V ALUE D ATA record for operating time and another for operating hours. A lso report a S UMMARY V ALUE D ATA record for each parameter measured or calculated at that location to meet a regulatory requirement

. See Table 1 below for applicable parameters.

For units required to report heat input (HI) , you must include for each unit a S UMMARY V ALUE
D ATA record for HI whether the HI was actually measured at the unit level or apportioned (or summed) from another location or multiple locations.

Common Stacks or Pipes

Th e reporting period and cumulative heat input values for the stack or pipe (in mmBtu) must equal the sum of the HIs for the units associated with the stack or pipe. For the individual units, report S UMMARY V ALUE D ATA records only for HI , operating time, an d operating hours. Do not apportion SO 2 mass emissions, CO 2 mass emissions, or average NO

x emission rates to the

individual units.

Environmental Protection Agency Emissions Reporting Instructions

-- Page 7March 07, 2012 September 19, 2012 2.1 Sum mary Value Data

Multiple Stacks or Pipes

For these configurations, report only the reporting period and cumulative HI , operating time, operating hours , and weighted average NO

x em ission rates in the unit- level S UMMARY V ALUE
D ATA records. Do not report quarterly and cumulative SO 2 or CO 2 mass emissions at the unit level. The reported quarterly or cumulative HI value for the unit must equal the sum of the corresponding HI values reported for the individual stacks, ducts, or pipes.

Complex Stack Configurations

A complex stack configuration exists where a unit ' s emissions are measured at more than one

stack location and where at least one of these stack locations is a common stack shared with one

or more other units.

For the purposes of quarterly and cumulative HI accounting, the sum of the HIs for all units associated with all stacks in a complex configuration must equal the sum of th e stack HIs for all of the stacks. For example, if emissions from scrubbed Units 1, 2, and 3 are measured at CS1 during normal unit operation and are measured at CS2 during scrubber bypass hours, the sum of

the HIs for Units 1, 2, and 3 must equal the sum of the HIs for CS1 and CS2.

See "Specific Considerations" below for information about how t o calculate summary value s.

Report the cumulative parameter value (i.e., emissions or time) as measured from the beginning of the current reporting period to the end of the current reporting period. This will generally be the quarterly total (or average) , except for the second calendar quarter file for ozone season only reporters. For those files, this value is the total (or average) for just May and June. The value should be rounded to the number of decimal places according to Table 2. If ther e was no operation at this location during the reporting period, report zero.

Ozone Season t o Date Total
Element Name: OzoneSeasonToDateTotal

For locations subject to ozone season only programs, report the cumulative parameter value (i.e.,

emissions or time) for the ozone season as follows: For a first quarter report, leave this field blank. For a second quarter report, report the sum parameter value (i.e., emissions or time) from the beginning of the ozone season (May 1) to the end of the reporting period. For a third quarter report, report the sum of the Ozone Season to Date Total value reported in the second quarter plus the quarterly value for the parameter reported for the third quarter. For a fourth quarter report, report the Ozone Season to date total from the third quarter report. All values should be rounded to the number of decimal places according to Table 2. If there was no operation at this location during the ozone season, report zero. For locations not subject to ozone season only programs, leave this field blank.

Year t o Date Total
Element Name: YearToDateTotal

For locations that report year-round, report the cumulative sum of current year quarterly totals for each parameter value (i.e., emissions or time) as follows: For a first quarter report, report the sum parameter value (i.e., emissions or time) for the quarter. For subsequent quarters, report the

sum of the current reporting period plus the quarterly values for the parameter reported in the previous quarters. For examp le, the Year to Date total for quarter three would be calculated by summing the current quarter three reporting period value with the previously reported quarter one and quarter two values. The value should be rounded to the number of decimal places

accor ding to Table 2. If there was no operation at this location during the calendar year- to

Specific Considerations

Operating Time and Operating Hours

● Operating Time is the sum of the hourly OperatingTime in H OURLY O PERATING D ATA records. Operating Hours is a count of H OURLY O PERATING D ATA records with OperatingTime greater than zero.

SO2M, NOXM , HIT, and CO2M from Hourly Data

● For non-L ow M ass E missions (LME) locations, t o calculate Reporting Period, Year to

Date , and Ozone Season to Date totals for SO2M, and NOXM , multiply each hourly rate value reported in the D ERIVED H OURLY V ALUE record by the corresponding operating

time in the H OURLY O PERATI NG record, sum those values, and then divide by 2 ,000. Round the resulting sum to the appropriate number of decimal places per Table 2. For CO2M, follow the same procedure but do not divide by 2,000.

● For LME units, to calculate Reporting Period, Year to Date, and Ozone Season to Date totals for SO2M, NOXM and HIT, sum the values in the D ERIVED H OURLY V ALUE records and divide by 2,000. Round the resulting sum to the appropriate number of decimal places per Table 2. For CO2M, follow the same procedure but do not divide by
2,000.

● If a common fuel pipe (or supply tank) serves a group of LME units and the long- term fuel flow option is used to quantify heat input, report the cumulative heat input for t he group of units under the common pipe (or tank) ID. If more than one common pipe (or tank) serves the same group of LME units, report a separate S UMMARY V ALUE D ATA
record for Total Heat Input ( HIT ) for each pipe (or tank).

Emissions Reporting Instructions

-- Page 10 Environmental Protection Agency2.1 Summary Value Data March 07, 2012 September 19, 2012

CO2M from Daily Data

● If CO 2 mass is calculated on a daily basis and reported in the D AILY E MISSION S D ATA record, calculate Reporting Period, Year to Date, an d Ozone Season to Date for CO2M by summing the values in these records. Round the resulting sum to the appropriate

number of decimal places per Table 2.

NO

x Emission Rate

● For non-Acid Rain units, do not report a S UMMARY V ALUE D ATA record for NOXR, even

if the NO

x emission rate is calculated on an hourly basis for the purpose of determining

NO

x mass rate (lb/hr).

● Calculate summary NO

x emission rates as a straight arithm etic average of the NO

x emission rates for all operating hours in the reporting period, ozone season, or year

- to

date period , as reported in the D ERIVED H OURLY V ALUE D ATA . If the recorded NO

x emission rate is zero, include these hours in the average only if the operating time for the hour is greater than zero.

● Do not weight the quarterly or cumulative average NO

x emission rate for partial operating hours (i.e., count all hourly NO

x emission rates equally, irrespective of the unit operating time). Report both the quarterly and cumulative average NO

x emission r ates for the unit or stack to three decimal places.

● For simple multiple stack or multiple duct configurations in which NO

x emissions and heat input are monitored separately in each of the stacks or ducts, you must calculate and report the quarterly and cumulative arithmetic average NO

x emission rate for each stackor duct, and you must also calculate and report a quarterly and cumulative heat inputweighted NO

x emission rate for the unit. Determine the heat input-weighted averages for the unit as follows. First, use the reported hourly data (i.e., stack level NO

x emission and heat input rates) and the following formula to calculate a heat input-weighted unit NO

x emission rate for each stack operating hour in the quarter:

(NO

x Rate) A (Heat Input) A + (NO

x Rate) B (Heat Input) B Hourly Unit NO

x Emission Rate (lb/mmBtu) = (Heat Input ) A + (Heat Input) B

● In the formula above, the term " Heat Input " for multiple stack A or B is the product of the hourly HI rate for the stack and the corresponding operating time for the stack.

● When a multiple -stack configuration is selected for a combined- cycle combustio n turbine (CT) that: (a) uses the provisions of Appendix D to Part 75 for unit HI ; and (b) has a main stack and bypass stack configuration; and (c) has NO

x - diluent monitoring systems on both the main and bypass stacks, the mathematics are slightly different. In this case, for any unit operating hour in which gases flow through both stacks for any part of the hour, a time-weighted, rather than a heat-input-weighed unit- level NO

x emission rate is calculated, using an equation similar to the one above, excep t that the terms " (Heat Input)A" and " (Heat Input)B " are replaced with tA and tB, respectively, where tA and tB

Environmental Protection Agency Emissions Reporting Instructions

-- Page 11March 07, 2012 September 19, 2012 2.1 Sum mary Value Data

are the main stack operating time and bypass stack operating time, respectively. The

time

- weighted hourly average NO

x emission rates are then used to determine the quarterly and cumulative NO

x emission rates for the unit.

● The quarterly heat input- weighted average NO

x emission rate for the unit is then determined by taking the sum of all of the hourly heat input- weighted NO

x emission rates for the quarter and dividing this sum by the total number of unit operating hours in the quarter. In determining the number of unit operating hours in the quarter, each partialoperating hour is counted as a full hour of unit operation. The cumulative heat inputweighted average NO

x emission rate for the unit is determined in the same w ay as the quarterly average for the unit, except that the terms " for the quarter " and "in the quarter" are replaced, respectively, with the terms, "for the year, to date" and "in the year, to date."

● For Acid Rain Program (ARP) LME units, determine the quarterly average NO

x emission rate for each unit as follows: Sum all of the hourly NO

x mass values from the D ERIVED
H OURLY V ALUE records for NO

x to get the total NO

x mass for the quarter. Then, sum the hourly HI values from the D ERIVED H OURLY V ALUE records for HI to obtain the HIT for the quarter. Divide the total NO

x mass for the quarter by the total quarterly HI , to determine the quarterly NO

x emission rate in lb/mmBtu. Calculate the cumulative ( year

to

- date) NO

x emission rate by separately summing the hourly NO

x mass and HI values over all operating hours in all quarters, and then dividing the NO

x mass sum by the HI

sum.

level calibration error test injections each pass the standard performance specification in sequence. Partial calibrations, where only one injection level is completed and passes the performance specification, may not be reported as

" PASSED ." Ra ther

, these may either be omitted from the electronic report or reported as " INC

. "

PASSAPS This code applies to daily calibration tests only. Report whenever the standard performance specification was not met for one or both injections, but the alternati ve performance specification (as described in Appendix B, Section 2.1.4(a)) was met for whichever injections did not meet the standard specification.

FAILED Report whenever the applicable performance specification is not met for the test. For daily calib ration error tests, report the test as failed whenever either the zero

level calibration error test or upscale

- level calibration error test (or both) have failed to meet the applicable performance specification. Partial calibrations, where only one inject ion level is completed and failed, must be reported as " FAILED ." Data for the systems associated with the specified component will be considered invalid

until a subsequent retest is passed.

INC Report whenever a calibration error test is not completed at both required

ca libration levels and the completed calibration injection passes the applicable performance specification tests. Incomplete tests have no affect on data validation and do not satisfy the daily calibration requirements of Part 75.

ABORTED Report whenever a test is aborted due to a malfunction of the monitoring system. Data for the systems associated with the specified component will be considered

invalid until a subsequent retest is passed.

Span Scale Code

Element Name: SpanScaleCode

For Daily Calibration tests, report whether the component or the range of the instrument tested is high (H) or low (L) scale (I f the component is a single range and no default high range is in use, enter "H") . Do not report a span scale code for flow monitor components.

D AILY C ALIBRATION D ATA Overview

Description of Data

Th e D AILY C ALIBRATION D ATA record is used to report the details of each daily calibration error test sequence completed

. You must report a D AILY C ALIBRATION D ATA record for each calibration error test performed that affect s data validation. A complete D AIL Y C ALIBRATION
D ATA record should contain data for both the zero and upscale calibration point.

Partial calibrati on error tests (where the tested level passes the applicable specification) do not satisfy the daily calibration error requirements and are n ot required to be reported since they have no affect on data validation. If such calibrations are included in the emissions report, then report the result as " INC " in the D AILY T EST S UMMARY D ATA record. Partial calibration error tests where the tested level fails to meet the applicable specification must be reported as a

" FAILED " test. You are not required to report additional failed calibration tests for a component when the data from that component is already considered invalid due to a previously fail ed

calibration error test. However, please note that tests reported as "FAILED" should be reported with all the necessary fields completed. Daily calibration error tests conducted with expired gas cylinders, gas cylinders obtained from a vendor not participating in the PGVP program, or gas cylinders containing concentrations outside the required percentage of Monitor Span Value record are considered invalid and should not be reported.

For more information concerning this record regarding moisture monitor ing systems, flow monitors, maintenance procedures, or dual range analyzers, see the "Specific Considerations"

Specific Considerations

Maintenance Procedures

● During maintenance procedures, the calibration gas injections used during those procedures do not have to be reported if the results of the calibration gas injection do not indicate that the control status of the monitor has changed. For instance, if a monitoring system is already out -of- control and calibration gases are injected as part of the maintenance procedures, the results of these injections do not have to be reported. Only the results of the post- maintenance calibration error test which is used to validate the subsequent emissions data must be reported. Similarly, if as part of a maintenance procedure on one monitor, calibration gases must be injected into other monitors, the results of these injections do not have to be reported as long as the y are within the calibration error specification. If the results of these injections indicate that any monitoring system is out -of-control, these injections must be reported and considered to

be a failed calibration error test.

Components Belonging to Mu ltiple Systems

● If a component is part of two (or more) systems (for example, a CO 2 analyzer used both as a primary CO 2 monitor and as a diluent monitor in a NO

x - diluent monitoring system)

the calibration error test should only be reported once, using the component ID. Data

Emissions Reporting Instructions

-- Page 24 Environme ntal Protection Agency2.2.1 Daily Calibration Data March 07, 2012 September 19, 2012

validation for each monitoring system which the component is part of will be determined based on this single test record. Moisture Monitoring Systems

● For moisture monitoring systems consisting of wet - and dry- basis O 2 monitors, report

two calibr ations only if the wet and dry readings are obtained from two different analyzers. Report only the dry- basis O 2 calibration when a single analyzer is used for both wet and dry oxygen.

Flow Monitoring Systems

● For flow monitoring systems comprised of tw o flow components, perform and report a daily calibration for each flow component in the system.

Dual Range Monitors

● For dual range monitors, perform and report daily calibrations for the instrument range(s) used during the day.

Provisions for Conducting Daily Calibration

● Conduct the daily calibration according to the requirements of 40 CFR Part 75, Appendices A and B. Daily calibrations validate the acceptability of emissions data from each monitoring component.

x emissions data from a combinedcycle combustion turbine that: (a) uses Appendix D to measure the unit-level heat input; and (b)

has a NO

x - diluent monitoring system installed on each stack (i.e. , on the main stack and the bypass stack), report the stack operating times as follows:

● For any hour in which all of the exhaust gases flow through one stack or the other, the operating time for the stack that is in use will be equal to the unit operating time for that hour, and the operating time for the other stack will be 0.00; and

● For a transition hour, in which gases flow through both stacks during the entire hour or any part of the hour:

-- Report that fraction of the hour (if any) in which gases flow only through the main

stack as the " main stack operating time ;" and

-- Report the remainder of the hour in which gases either flow through both stacks simultaneously or flow only through the bypass stack as the "bypass stack opera ting

time. "

Operating Time for LME Units

Report the fraction of the clock hour during which the unit combusted any fuel (or the fraction of the clock hour during which the stack or pipe was used).

Report a unit operating time of "0.00" for any clock hour in which the unit did not operate.

Hour Load

Report hourly load information as either steam load or gross unit load. The units for average hourly gross unit load are to be reported in megawatts of electrical generation or in e ither 1,000

lbs/hr or mmBtu/hr of steam generation

. Note that this value represents an hourly rate and not the total load for the hour. Do not correct steam load for standard temperature and pressure; use steam load at measured temperature and pressure ( see Part 75, Appendix C, Section 2.2.1).

If you convert auxiliary heat input to the megawatts equivalent ( e.g. , for a heat recovery steam generator with a duct burner) and add that value to megawatts for a gas turbine, you should report the unit electric load in megawatts.

For all multiple -stack configurations, for each unit operating hour in which gases flow through a particular stack or duct, report the unit load in both the stack-level and unit- level H OURLY
O PERATING D ATA records for that hour.

Load Range
Element Name: LoadRange

Report an operating load range (load bin number) for each operating hour (see Appendix C to Part 75) for units that produce electrical or steam load. For units that do not produce electrical or

steam load (e.g., cement kilns, refinery process heaters, etc.), report the operational bin number, if operational bins are used for missing data purposes. If the operational bin number is indeterminable, report " 0. "

For a monitored common stack, the load bins are defined at the common stack on the basis of combined unit load, and load-based missing data routines are applied at the common stack. Therefore for each unit operating hour, report the common stack load bin number in both the

common stack and unit-l evel H OURLY O PERATING D ATA records.

M ONITOR H OURLY V ALUE D ATA Overview

Description of Data

Use the M ONITOR H OURLY V ALUE D ATA (MHV) record to report each value measured by a

continuous emissions or stack flow monitoring system (or , if applicable, the missing data substitution value for the parameter). The monitored emission values can include SO 2 concentration, NO

x concentration, CO 2 concentration, O 2 concentration, H 2 O concentration (moisture), and volumetric flow. These instructions contain sub sect ions of each measured parameter, to give specific stipulations on how to report for that particular parameter.

SO 2 Concentration

If you use continuous emissions monitoring systems (CEM S ) to determine SO 2 mass emissions, report SO 2 concentration in a n MHV record for each hour or partial hour of unit operation, with one exception: do not report an MHV record for hours in which only gaseous fuel is combusted, if you account for SO 2 mass emissions during those hours using the provisions of §75.11(e)(1) in

li eu of operating and recording data from the SO 2 monitoring system.

Volumetric Flow

If you use stack flow monitoring to determine hourly heat input rate or SO 2 , CO 2 , or NO

x mass emissions, report volumetric flow in an MHV record for each operating hour or partial operating

hour.

Note that fo r units with add-on NO

x emission controls, hours in which the flue gases are discharged through an unmonitored bypass stack are considered to be missing data hours. However, when the outlet NO

x monitor is unavailable and proper operation of the emission controls is not verified, §75.34 (a)(1) allows you to report data from a certified NO

For a summary of these requirements, see Table 11 below.

Reporting of High Range and Full Scale Exceedance Defaults

x concentration as follows:

(a) For NO

x emission rate (MER) as a substitute data value in a DHV re cord using an MODC of 25.

(c) Where both NO

1. If a quality -assured diluent value is available for the hour, treat the hour as a qualityassured monitor operating hour and include it in the missing data lookback and as an available hour for percent monitor data availability calculations. Also, use the NO

x concentration value in conjunction with the quality- assured average diluent gas concentration for the hour to calculate and report NO

3 If the CO 2 value is used to calculate heat input or CO 2 mass rate , report an MHV record f or CO2C for every operating hour. Otherwise, do not report CO2C MHV records for missing data hours.

(a) Whenever you use a CO 2 monitor to determine CO 2 mass emissions and /or for heat input rate:

Report a MHV record using the CO 2 Monitoring System ID, f or each hour or partial hour of unit operation. When the hourly CO 2 concentration is missing, or for hours in which the flue gases are discharged through an unmonitored bypass stack, use the missing data routines in §75.35 and 75.36 to provide substitute data values.

Emissions Rep orting Instructions

If the CO 2 monitor is also used as the diluent monitor for a NO

x - diluent monitoring system, whenever a CO 2 RATA is failed on the CO 2 monitoring system , then both the

CO 2 and NO

x -diluent monitoring systems are considered out-of-control. ( See Appendix B §2.3.2(g)). Report the applicable substitute CO 2 concentration data in the MHV record using the applicable missing data procedures for CO2C. For NO

x emission rate

, report the appropriate substitute data value in the DHV record.

However, if the CO 2 data for the CO 2 monitoring system is considered out-of-control due to the expiration of the applicable CO 2 RATA but the NO

x RATA has not yet expired

, 1 then substitute data should only be used for CO 2 mass and heat input rate

calculations and not for calculation of the NO

x emission rate. For NO

x emission rate, the

actual measure d CO 2 concentration should be used. In such cases, report two CO 2 concentrations for each hour until a CO 2 RATA is completed. First, report the appropriate substitute CO 2 data using the CO 2 System ID . Second , report the actual CO 2 value recorded by the CO 2 component, leaving the System ID blank. (The actual CO 2 value will be used in the NO

x emission rate calculation for the hour, while the substitute

data value will be used in the CO 2 mass a nd heat input rate calculations.)

(b) If you use the CO 2 monitor only to calculate NO

x emission rate:

Report a n MHV record for CO 2 concentration . Leave the Monitoring System ID blank. Do not report an MHV record for the hour if: (1) a quality- assured CO 2 concentration is not available; or (2) a quality- assured NO

x concentration is not available; or (3) both (1) and (2). Instead, report a substitute data value for NO

x emission rate in the DHV record.

Note that hours in which the flue gases are discharged through an unmonitored bypass stack are considered to be missing data hours. For these hours, do not report a MHV record. In the DHV record, report the NO

x MER and MODC of "23."

When a default high range value (200 percent of M PC) or a f ull- scale exceedance value (200 percent of the range) is used in the calculation of the hourly average NO

x concentration, the NO

x concentration is considered to be both quality- assured and available. Therefore, if a quality

- assured CO 2 concentra tion is available for that hour, report a MHV record and calculate the NO

x emission rate in the usual manner. However, if a quality- assured CO 2 concentration is not available for that hour, the NO

x emission rate data for the hour are considered missing. In that case, do not report a MHV record for the hour and report the maximum potential NO

x emission rate (MER) as a substitute data value in DHV record, using an MODC of "25."

O 2 Concentration

Report an MHV record for O 2 concentration for each hour in wh ich you use the O 2 concentration to determine the hourly NO

x emission rate, heat input rate, or CO 2 concentration . Report two

MHV records for O 2 concentra tion (one wet-basis and one dry-basis) for each hour in which you

use O 2 concentration to determine p ercent moisture.

1 Note that this situation should only arise if the NO

x emission rate RATA was done using O 2 as the diluent for the

reference method or if the CO 2 RATA data are not su bmitted. If the RATA was conducted using a CO 2 diluent in the reference method, then there should be sufficient CO 2 data available to submit a RATA for the CO 2 system.

(a) Whenever you use an O 2 monitor to determine CO 2 concentration, CO 2 mass emission s, and/or for heat input rate (as part of a CO 2 monitoring system):

Report an MHV record using the CO 2 Monitoring System ID, for each hour or partial hour of unit operation in which a quality- assured O 2 value is obtained. When the hourly

O 2 concentration is missing, or for hours in which the flue gases are discharged through an unmonitored bypass stack, use the missing data routines in §75.36 to provide

For h eat input that is calculated from the O 2 , report the applicable substitute O 2 concentration data in the MHV record using the applicable missing data procedures for

O2C. For NO

x emission rate. The actual measured O 2 concentration should be used to calculate NO

x emission rate. In such cases, report an

additional O 2 concentration record for each hour until an O 2 RATA is completed. First,

report the appropriate substitute O 2 data using the O 2 System ID . Secondly, report the

actual O 2 value recorded by the O 2 component leaving the System ID blank. (The

recorded O 2 value will be used in the NO

(d) If you also use wet and dry O 2 monitors to determine the hourly percent moisture:

Report two O 2 MHV records for each hour. Report the wet O 2 measurement with a "W" as the Moisture Basis data element and report the dry O 2 measurement with a "D" as the Moisture Basis data element. If either the wet or dry O 2 component is also used to calculate heat input, NO

The Part 75 missing data procedures for moisture are found in §75.37. These procedures are modeled after the standard missing data procedures for SO 2 . In most instances, the moisture missing data algorithm is the inverse of the SO 2 algorithm ( i.e., the lower moisture values are more conservative and therefore an inverted moisture missing data algorithm must be applied (using 10 th percentile va lues instead of 90 th percentile values, minimum values instead of maximum values, etc .)). However, when Equations 19-3, 19-4, or 19-8 from Method 19 of 40

CFR Part 60 are used to determine NO

conservative an d therefore the standard SO 2 missing data algorithm must be applied.

x emission rate for an hour, report the actual CO 2 concentration for the hour and the appropriate MODC (either "01" or "02" ). See instructions under Description of Data for CO 2 Concentration.

Emissions Rep orting Instructions

-- Page 46 Environmental Protection Agency2.4.1 Monitor Hourly Value Data March 07, 2012 September 19, 2012

O 2 Concentration

Report O 2 concentration for the hou r, expressed in %O 2, and round the resulting value to the appropriate number of decimal places per Table 16. For each hour in which you use the diluent cap value to calculate NO

x emission rate

, report the actual quality

- assured O 2 concentration and

approp riate MODC ( "01" through "04"). For each such hour, report an MODC of "14" in the

NO

x emission rate DHV record , to indicate that the diluent cap is being used for NO

x emission

rate.

For any hour in which there is a full scale exceedance of the O 2 monitor range, report the appropriate diluent cap value for the type of unit and an MODC of "20." You must also report a default record in the monitoring plan with a parameter code of O2X and a Default Purpose Code

of " DC " containing this value even if you do not calculate an hourly NO

x Emissions Rate. (Note that you may instead report a time weighted average calculated using the diluent cap value for the portion of the hour that the monitoring range was exceeded with the quality assured data collected during the portion of the hour when the range was not exceeded. In this case, report the hourly average but use an MODC of "20" to indicate a range exceedance has occurred during the hour.)

If you use wet and dry O 2 monitors to determine the hourly percent moisture and both values are

q uality

- assured , report two O 2 MHV records for each hour.

If you use O 2 concentration for the heat input rate calculation , report the appropriate substitute data value in this field when a quality- assured O 2 concentration for the hour is unavailable or for hours in which the flue gases are discharged through an unmonitored bypass stack. Otherwise, if a quality

- assured O 2 concentration is not obtained, do not report an MHV record for the hour.

Moisture

Report moisture for the hour, expressed in %H 2 O, and round the resulting value, obtained either from a moisture sensor, or for saturated gas streams, from a temperature sensor and look-up

table , to the appropriate number of decimal places per Table 16. Report the appropriate substitute data value for hours in which a quality- assured moisture percentage is unavailable or for hours in which the flue gases are discharged through an unmonitored bypass stack.

Volumetric Flow

For each operating hour (or partial operating hour) in which a quality

- assured flow rate was measured (MODC "01" through "04" and "54"), report the unadjusted flow rate in units of scfh (wet

- basis). Report flow rate to the appropriate number of decimal places per Table 16. For missing data hours, leave this field blank (this includes hours in which the flue gases are discharged through an unmonitored bypass stack).

If a start -up or shut-down hour results in a stack flow rate that is too low to be registered by the stack flow monitor, you may report a default minimum stack flow rate of 1,000 scfh. Report an MODC of " 55" for the hour. Manual entry of this MODC is permitted.

Adjusted Hourly Value

Element Name: AdjustedHourlyValue

Leave this field blank for parameters CO2C, H2O, and O2C.

SO 2 Concentration

For each hour in which you obtain quality- assured values, apply the appropriate bias adjustment factor (BAF) to the rounded average SO 2 concentration for the hour. Report the adjusted SO 2 concentration for the hour in ppm and round the resulting value to the appropriate number of decimal places per Table 16.

Note that for an initial certification, analyzer replacement, or complete monitoring system replacement (as indicated by reporting a QA AND C ERTIFICATION E VENT record with a QACertificationEventCode value of "100," "101," "120," or "125"), if you are using conditional data validation, the BAF is uncertain during the conditional data period. Therefore, apply a BAF of 1.000 from the beginning of the conditional data validation period to the completion ho ur of

the certification or recertification RATA

.

For each hour in which you use missing data procedures, report the substitute data value.

For each hour in which the flue gases are routed through an unmonitored bypass stack, or when

the outlet SO 2 monitor is unavailable and proper operation of the emission controls is not verified, you may either report the MPC in this field or, if data are available from a certified inlet monitor, report the bias-adjusted SO 2 concentration measured by the monitor.

For e ach hour in which only very low sulfur fuel (as defined in §72.2) is combusted, report the

bias -adjusted hourly average SO 2 concentration , unless it is less than 2.0 ppm, in which case,

report "2.0 ppm."

For each hour in which a default high range value is used in the calculation of the hourly average

SO 2 concentration, report the bias-adjusted hourly average in this field unless application of the

BAF causes t he hourly average to exceed 200 percent of the MPC, in which case, report 200 percent of the MPC.

When a full- scale exceedance o f the high range occurs and 200 percent of the range is used in the calculation of the hourly average SO 2 concentration, report the bias-adjusted hourly average in this field unless application of the BAF causes the hourly a verage to exceed 200 percent of the range, in which case, report 200 percent of the range.

Refer to the Part 75 Emissions Monitoring Policy Manual for a further discussion of overscaling and use of the default high range value.

NO

Report data in this field only if you use NO

x concentration times stack flow rate to determine

NO

x mass emissions. L eave this field blank if you do not have a NO

x concentration system

.

Emissions Rep orting Instructions

-- Page 48 Environmental Protection Agency2.4.1 Monitor Hourly Value Data March 07, 2012 September 19, 2012

For each hour in which you obtain a quality-assured value, apply the appropr iate adjustment factor (1.000 or system BAF) to the rounded average NO

x concentration for the hour. Report the adjusted average NO

x concentration for the hour in ppm and round the resulting value to the appropriate number of decimal places per Table 16.

Note that for an initial certification, analyzer replacement, or complete monitoring system replacement (as indicated by reporting a QA AND C ERTIFICATION E VENT record with a QACertificationEventCode value of "100," "101," "120," or "125"), if you are using conditional data validation, the BAF is uncertain during the conditional data period. Therefore, apply a BAF of 1.000 from the beginning of the conditional data validation period to the completion hour of

the certification or recertification RATA

.

For e ach hour in which NO

x concentration is missing, report the substitute NO

x concentration

value.

For each hour in which a default high range value is used in the calculation of the hourly average

NO

x concentration, report the bias-adjusted hourly average in this field , unless it exceeds 200

percent of the MPC, in which case, report 200 percent of the MPC.

When a full- scale exceedance o f the high range occurs and 200 percent of the range is used in the calculation of the hourly average NO

x concentration, report the bias-adjusted hourly average in

this field , unless it exceeds 200 percent of the r ange, in which case, report 200 percent of the

range.

For units with add-on NO

x emission controls, if you report data from a certified NO

x monitor at the control device inlet during hours in which the outlet NO

x monitor is unavailable and proper operation of the emission controls is not verified, report the average, bias-adjusted NO

x concentration recorded by the monitor. Include these hours in the missing data lookbacks and

treat them as available hours in the PMA calculations.

Volumetric Flow

For hours in which quality-assured data are obtained, apply the appropriate bias adjustment factor (1.000 or BAF) to the rounded quality-assured value and report the adjusted stack flow for

the hour. Report the resulting value to the appropriate number of decimal places per Table 16. For each hour in which missing data procedures are used to report data, report the substitute data value. When the flue gases are discharged through an unmonitored bypass stack, report the appropriate substitute data value for flow rate (under §75.33) in this field. Do not leave this field

blank.

Note that for an initial certification, analyzer replacement, or monitoring system replacement (a s indicated by reporting a QA AND C ERTIFICATION E VENT record with a QACertificationEventCode value of "300" or "305"), if you are using conditional data validation, the BAF is uncertain during the conditional data period. Therefore, apply a BAF of 1.000 f rom the beginning of the conditional data validation period to the completion hour of the certification

or recertification RATA

For CEM Methods

Derived Hourly Heat Input Rate (mmBtu/hr)

For each unit or stack with a stack flow monitor and diluent monitor, report the calculated heat input rate in the AdjustedHourlyValue element of a D HV record. If you monitor heat input rate and report this record at a common stack, also apportion the heat input rate measured at the common stack to the individual units ( i.e. , report additional DHV records for heat input rate

under the associated Unit ID s). If you monitor heat input rate and report this record at multiple stacks, also report the heat input rate for the unit in an additional DHV record.

Derived SO 2 Hourly Mass Emission Rate (lb/hr)

For each unit or stack with an SO 2 CEMS (or using the F23 methodology per §75.11(e)(1)), report the calculated SO 2 mass emission rate in the AdjustedHourlyValue element of a DHV

record

.

If you monitor SO 2 mass emission rate and report this record at a common stack, do not apportion the SO 2 mass emission ra te measured at the common stack to the individual units ( i.e.

, do not report any additional DHV records under the associated Unit IDs).

If, for a particular unit, you monitor SO 2 mass emission rate at multiple stacks (or ducts), do not report the combined SO 2 mass emission rate for the unit ( i.e. , do not report any unit- level DHV records).

Derived NO

x Hourly Emission Rate (lb/mmBtu)

For each unit or stack with a NO

x emission rate CEMS, report the calculated NO

x emission rate

in the Una djustedHourlyValue element and the bias- adjusted emission rate in the AdjustedHourlyValue element of a DHV record . If you monitor NO

x emission rate and report this record at a common stack, do not apportion the NO

x emission rate measured at the common

stack to the individu al units ( i.e. , do not report any additional DHV records under the associated Unit IDs).

If, for a particular unit, you monitor NO

x emission rate at multiple stacks (or ducts), calculate the

heat -input weighted hourly emission rate for the unit, but do not report those hourly unit level values (i.e. , do not report any unit- level DHV records for NO

x emission rate ). Rather, only use them to calculate the quarterly and cumulative NO

x emission rates for the unit. Report these quarterly and cumulative values in the unit- level S UMMARY V ALUE D ATA record.

For a combined- cycle turbine that uses a multiple

- stack configuration, report separate stack

- level

DHV records for each hour in which there is both main stack and bypass stack operating time. Then, calculate a time -weighted unit- level NO

x emission rate for each hour, as described in the

S UMMARY V ALUE D ATA record instructions. Store, but do not report, these time-weighted, hourly unit- level emission rates. Rather, only use them to calculate the quarterly and c umulative

unit- level NO

x emission rates.

Emissions Reporting Instructions

For Derived NO

x Mass Emission Rate (lb/hr)

For each unit, stack, or pipe at which NO

x mass emissions are measured or estimated, s ubmit a

DHV record, for every hour in the reporting period that the unit or stack o perates.

If you monitor NO

x mass emissions and report this record at a common stack, do not apportion

the NO

x mass emissions measured at the common stack to the individual units ( i.e. , do not report any additional DHV record s under the associated Unit IDs ).

If, for a particular unit, NO

x mass emissions is monitored at multiple stacks (or ducts), do not report the combined hourly NO

x mass emissions for the unit ( i.e. , do not report any unit- level

DHV records for NO

x mass rate ).

Derived CO 2 Mass Emission Rate (tons /hr)

For any operating hour (or partial hour) for each unit, stack, or pipe at which CO 2 emissions are monitored using CEMS, including the use of O 2 CEMS

, report CO 2 mass emission rate in a DHV

record.

If you monitor CO 2 mass emission rate an d report this record at a common stack, do not apportion the CO 2 mass emission rate measured at the common stack to the individual units ( i.e.

, do not report any additional DHV records under the associated unit IDs).

If, for a particular unit, CO 2 mass em ission rate is monitored at multiple stacks (or ducts), do not report the combined CO 2 mass emission rate for the unit ( i.e. , do not report any unit- level DHV

records ).

Derived CO 2 Concentration

For any operating hour (or partial hour) for each unit or stack at which CO 2 concentration is

determined by calculating it from O 2 readings, report the derived CO 2 concentration value for each operating hour or partial operating hour in this record. Note that measured CO 2 concentration from a CO 2 system utilizin g a CO 2 monitor should be recorded in the M ONITOR
H OURLY V ALUE D ATA (MHV) record.

Derived H 2 O (Moisture) Value

For any operating hour (or partial hour) for each unit or stack at which moisture is determined by calculating it from wet and dry O 2 readings , report the derived moisture value for each operating hour or partial operating hour in this record.

● Note that m easured H 2 O values from a moisture sensor or a temperature sensor and lookup table, if reporting for saturated gas streams , should be reported in the MHV record.

If you use a fuel-specific default moisture value, as allowed under §75.11 or §75.12 (for coal and wood-burning units and natural gas

- fired boilers ) and you have just one default value defined in your monitoring plan, do not report a MHV record or a DHV record on an hourly basis.

calculations in a n H 2 O D ERIVED H OURLY V ALUE D ATA record with a Method of Determination Code ( MODC ) of "40" on an hourl y basis.

Derived SO 2 Hourly Emission Rate (lb/mmBtu)

If you are using the F23 methodology to calculate the SO 2 mass rate per § 75.11(e)(1) and you

have defined more than one fuel- specific SO 2 emission rate default value in your monitoring plan, report th e fuel

- specific or pro -rated default value used in your emissions calculations in an

SO2R D ERIVED H OURLY V ALUE D ATA record with an MODC of "40" on an hourly basis.

Appendix D Methods

Heat Input

If you use Appendix D fuel flowmetering to determine heat input, report the heat input rate calculated for each fuel in the appropriate H OURLY P ARAMETER F UEL F LOW D ATA records. In addition, report the total heat input rate for the hour in a DHV record for the location. (You must report this record even if only one fuel was combusted during the hour.) If the fuel flowmeter ing is at a common pipe, also report the apportioned hourly heat input rate in a DHV record for each unit that is part of the common pipe.

SO 2

If you use Appendix D fuel flowmetering to determine SO 2 , report the SO 2 mass emission rate calculated for each fuel in the appropriate H OURLY P ARAMETER F UEL F LOW D ATA record. In addition, report the total SO 2 mass emission rate for the hour in a DHV record for the location. (You must report this record even if only one fuel was combusted during the hour.) If the fuel

flowmeter ing is at a common pipe, do not report hourly apportioned SO 2 for the units.

Appendix G Method for Hourly CO 2

If you use Equation G-4 to determine hourly CO 2 , report the CO 2 mass emission rate calculated for each fuel in the appropriate H OURLY P ARAMETER F UEL F LOW D ATA record. In addition, report the total CO 2 mass emission rate for the hour in a DHV record. (You must report this record even if only one fuel was combusted during the hour.)

Appendix E Method for Hourly NO

x Emission Rate

If you use Appendix E to determine NO

x emission rate, report the overall NO

x emission rate for

the hour in a DHV record. If you burn a single, consistent blend of fuels and established a si ngle Appendix E curve for that fuel blend, report all the Appendix E related information in this DHV record. If you established a separate Appendix E curve for each fuel, report the fuel- specific

NO

x emission rate data in the appropriate H OURLY P ARAMETER F UEL F LOW D ATA record and in addition, report the overall NO

x emission rate for the hour in a DHV record. (You must report this record even if only one fuel was combusted during the hour.)

Unadjusted Hourly Value

Eleme nt Name: UnadjustedHourlyValue

Report the unadjusted derived hourly value for the parameter specified, as follows:

NO

x Emission Rate from CEM

Calculate and report the NO

x emission rate (lb/mmBtu) based on the unadjusted NO

x concentration and unadjusted diluent (CO 2 or O 2 ) concentration recorded in the MHV record. Report the resulting value to the appropriate number of decimal places in Table 20. For hours in which you use missing data procedures leave this field blank, including hours in which the flue gases are discharged through an unmonitored bypass stack.

If you use Equation 19-3 or 19-5 to determine NO

x emission rate, you must use modified Equation 19-3D or 19- 5D (as app licable) instead of Equation 19-3 or 19-5, for hours in which you use the diluent cap (see Table 29 in the M ONITOR ING F ORMULA D ATA record in the Monitoring Plan Reporting Instructions ).

For all other parameters, leave this field blank.

Adjusted Hourly Value

Element Name: AdjustedHourlyValue

Report the adjusted or " final " derived hourly value for the parameter specified.

SO 2 Mass Emission Rate (lb/hr)

For CEM methods, this value is normally derived using the bias-adjusted stack flow and the biasadjusted SO 2 concentration (each reported in the MHV record ), in conjunction with the appropriate equation in Appendix F to Part 75. However, for an hour in which a very low sulfur fuel (see § 72.2) is combusted, the value may be calculated from a CEMS -derived heat input rate (i.e., from monitored stack flow rate, and diluent (CO 2 or O 2 ) concentration) and a default SO 2 emission rate using Equation F-23 (see §75.11(e)(1)).

For Appendix D units and pipes, report the total SO 2 mass emission rate for the location in this

field. Use formula D-12 to combine SO 2 mass emission rates fr om multiple fuels (as reported in

H OURLY P ARAMETER F UEL F LOW ).

Report all data for this element in lb/hr and to the appropriate number of decimal places per Table 20.

If you use NO

NO

CEM Systems

. For each hour in which you report NO

x emission rate in the Unadjusted Hourly Value element, apply the appropriate adjustment factor (1.000 or bias adjustment factor (BAF)) to the rounded average NO

x emission rate and report the adjusted NO

x emission rate for the hour. Report the resulting value to the appropriate number of decimal places per Table 20. Report the appropriate substitute data value for NO

x emission rate f or each hour that a quality

- assu red

emission rate is not obtained , including hours in which the flue gases are discharged through an unmonitored bypass stack. Do not leave this field blank.

Note that for an initial certification, analyzer replacement, or complete monitoring system

rep lacement (as indicated by reporting a QA C ERTIFICATION E VENT record with an Event Code of 100, 101, 120, 125, 151, 250, 255, 300 or 305), if you are using conditional data validation, the BAF is uncertain during the conditional data period. Therefore, apply a BAF of 1.000 from the beginning of the conditional data validation period to the completion hour of the certification

or recertification RATA

. For any other events that require a RATA, apply the BAF from their previous RATA during the conditional data period, unless that RATA failed or was aborted, in

which case use 1.000.

For a combined- cycle combustion turbine ( CT ) using a multiple -stack configuration to report

NO

x emission rate, use missing data substitution for any transition hour (i.e., an hour during which gases flow through both stacks), if either the main stack or bypass monitoring system is out of service, and draw the appropriate substitute data value from the bypass stack data pool.

If a full

- scale exceedance of the low NO

x range occurs an d you use a default high range value of 200 percent of the MPC in the calculation of the hourly average NO

x concentration reported in

the MHV record, or if a full

- scale exceedance of the high NO

x range oc curs and you use a value of 200 percent of the range in the calculation of the hourly average NO

x concentration reported

in the MHV record, use the reported NO

x concentration in conjunction with the quality- assured diluent concentration for the hour to calculate and report the NO

x emission rate. These hour s are treated as quality -assured monitor operating hours; they are included in missing data lookback and are treated as available hours for percent monitor data availability calculations.

If a diluent concentration is unavailable during an hour in which a full scale exceedance of the

NO

x analyzer occurs or an hour in which the default high range value is used, the NO

x emission rate for the hour is considered to be missing. In that case, do not report Monitor Hourly Value

for NO

x concentration for this h our since the NO

x emission rate cannot be calculated; instead, report the maximum potential NO

x emission rate (MER) in this field, and use an MODC of "25."

Appendix E Systems. Report the overall NO

x emission rate for the unit to the appropriate

number of decimal places per Table 20. If this value was determined from a consistent fuel mix curve, also report the appropriate System ID for the Appendix E NO

x system. If a single fuel curve or curves were defined, report the fuel- specific NO

x emission rate in the appropriate

P ARAMETER F UEL F LOW D ATA record(s), and report the combined NO

x emission rate for the unit

in this record.

CO 2 Concentration (D erived from O 2 Concentration) (pct)

Report the CO 2 Concentration for the hour to the appropriate number of deci mal places per Table

20. This is either the value calculated from a quality

- assured O 2 concentration value (as reported

in the MHV record), or the appropriate substitute data value, as specified in §75.35.

CO 2 Mass Emission Rate (ton s /hr)

If you are using CEMS, this value is derived using the bias-adjusted stack flow and either the unadjusted CO 2 concentration reported in the MHV record (if you are using a CO 2 analyzer), or

the CO 2 Concentration reported in the DHV record ( if you are using an O 2 analyzer ), in conjunction with the appropriate equation in Appendix F to Part 75.

For units using Appendix G, calculate and report, in P ARAMETER F UEL F LOW D ATA record(s)

, the

CO 2 mass emissions (tons/hr) for each fuel separately using Equation G-4. Then use Equation

G- 4A (see Table 32, M ONITOR ING F ORMULA D ATA record in the Monitoring Plan Reporting Instructions) to determine the combined CO 2 mass emission rate for the hour. Report the combined hourly CO 2 mass emission rate (tons/hr) in this field in the DHV re cord.

Report this element in tons per hour and to the appropriate number of decimal places per Table

20.

H 2 O (Moisture) (pct)

Report moisture for the hour, expressed in %H 2 O, rounded to one decimal place. Report the appropriate substitute data value for hours in which a quality- assured moisture percentage is unavailable or for hours in which the flue gases are discharged through an unmonitored bypass

stack.

Heat Input (HI) Rate (mmBtu/hr)

Report this value in mmBtu per hour (mmBtu/hr) and to the appropriate number of decimal places per Table 20. If you use CEMS to determine hourly heat input rate, calculate the hourly rate using the diluent gas concentration, bias-adjusted hourly stack flow rate, percent moisture (if appropriate), and F- factor.

If y ou measure and report heat input rate at a common stack or pipe, also apportion and report heat input rate at the unit level. This apportionment should be based on megawatts , steam load, or fuel flow rate, using Equation F- 21A, F -21B, or F-21D in Appendix F to Part 75, as applicable. These formulas use time -weighted hourly load to apportion the heat input rate

measured at a common stack to the individual units.

For each hour, the sum of the individual heat inputs in mmBtu ( i.e. , the sum of the individual unit heat input rates, each multiplied by the corresponding unit operating time) must equal the total common stack heat input in mmBtu ( i.e. , the common stack heat input rate multiplied by the common stack operating time).

Emissions Reporting Instructions

-- Page 64 Environmental Protection Agency2. 4 .2 Derived Hourly Value Data March 07, 2012 September 19, 2012

For a unit with a multiple stac k configuration, with flow rate and diluent monitors on each stack, calculate the hourly heat input rate for the unit using Equation F-21C in Appendix F to Part 75. Also use Equation F-21C for multiple pipe configurations.

For each hour, the total unit h eat input in mmBtu ( i.e. , the unit heat input rate multiplied by the unit operating time) must equal the sum of the individual stack (or pipe) heat inputs in mmBtu ( i.e. , the sum of the individual stack (or pipe) heat input rates, each multiplied by the

co rresponding stack (or pipe) operating time).

For Appendix D units combusting multiple fuels, report the hourly heat input rate calculated

from all fuels in the DHV record. Report this record even if only one fuel was combusted during

the hour.

For non-A cid Rain NO

x Budget Program units that use NO

x concentration times stack flow as the primary methodology to calculate NO

x mass emissions, rep ort the hourly heat input rate unless you are specifically exempted (e.g., by a State SIP) from reporting it for al location purposes. However, you must report unit operating time and load (except for non load- based units) for each hour in the H OURLY O PERATING D ATA record, even if you are not required to report hourly heat input.

If, for any operating hour, the heat input rate is calculated to be less than one mmBtu/hr,

substitute for that hour a value of one mmBtu/hr. Use an MODC of "26" for any such hours. This applies only to monitoring locations where CEM S are installed (i.e., where HI Rate is calculated using eq uation F- 15, F -16, F-17, or F-18.) This does not apply to HI Rate calculated through Appendix D or apportionment.

In the rare event no units attached to the common stack generated load (Load = 0) during the hour, heat input should be apportioned by opera ting time.

Total Heat Input (HIT) (mmBtu)

Report this value in mmBtu for LME units and to the appropriate number of decimal places per Table 20.

SO 2 Emission Rate (lb/mmBtu)

If you are using the F23 methodology to calculate the SO 2 mass rate per § 75.11(e)(1) and you

have defined more than one fuel- specific SO 2 emission rate default value in your monitoring plan, report the fuel- specific or pro

- rated default value in lb/mmBtu . Report the value to the appropriate number of decimal places per Table 20

.

LME Units

Report the value for each required parameter as total mass (or heat input) for the hour. Report each value to the appropriate number of decimal places per Table 20.

For CEM methods for parameters CO2C, NOXR or H2O, report one of the following MODCs as shown in Table 21 to identify the monitoring system or missing data procedure used to report the derived value or when you were directed to report it for an approved a lternative monitoring

system

. For parameter HI , use an MODC of "26" when the calculated Heat Input Rate is zero or negative and was therefore replaced with a value of 1.0 . Report an MODC of "40" for parameters SO2R and H2O when a fuel

- specific or pro

the derived value.

For all oth er parameter s, leave this field blank.

NO

x Hourly Emission Rate

Report an MODC of "14" when the diluent cap value for CO 2 or O 2 is used in place of the measured value reported in the MHV records. Also, be sure that you register the appropriate diluent cap value for the unit in the M ONITORING D EFAULT D ATA record in the monitoring plan

. A diluent cap value can only be used for calculating NO

x emission rate during operating hours

for which a quality

- assured measured diluent (CO 2 or O 2 ) value is obtained.

For full

- scale exceedances of a NO

x analyzer, EPA requires reporting of an MODC reflecting the monitoring system in use during the exceedance, or reporting an MODC of "25" if the diluent concentration normally reported in the MHV records is not quality-assured. Therefore, during

full

- scale exceedances, when 200 percent of MPC or 200 percent of range is reported for NO

x concentration in the MHV record and is used in conjunction with a quality -assured diluent gas

concentration to calculate the NO

x emission rate, report the MODC code associated with the monitoring system that is in use at the time of the full

- scale exceedance (for example, report "01" if the primary NO

x -diluent monitoring system is in use). If a full- scale exceedance of the NO

x analyzer occurs and no quality-assured diluent gas concentration for the hour is available, report

an MODC of "25" for that hour. Manual entry of an MODC of "21" is permitted.

Whenever a flowmeter is used to determine heat input rate or SO 2 or CO 2 emissions in acc ordance with Appendix D, report an H OURLY F UEL F LOW D ATA (HFF) record for each type of oil and/or gaseous fuel combusted during each operating hour using the Monitoring S ystem ID associated with the appropriate flowmeter monitoring system . Do not report an HFF record f or low mass emissions units (LME) that use a certified Appendix D fuel flowmeter for long term fuel flow

purposes ; use the L ONG T ERM F UEL F LOW (LTFF) record

.

To report hourly SO 2 mass emission rate, CO 2 mass emission rate and/or Heat Input, you must also submit the appropriate H OURLY P ARAMETER F UEL F LOW D ATA record s associated with each HFF

record

.

If you measure fuel flow at a common pipe location, report a HFF record using the Stack Pipe ID for each hour in which fuel is combusted by a unit served by the common pipe. Do not report HFF records for the individual units on an hourly basis. Apportion the heat input rate calculated at the common pipe location to each unit, using appropriate time-weighted apportionment formulas based on load (see Appendix F and the M ONITOR F ORMULA D ATA instructions). Report the apportioned hourly heat input rate values in separate D ERIVED H OURLY V ALUE D ATA (DHV)

Environmental Protection Agency Emissions Reporting Instructions

-- Page 73March 07, 2012 September 19, 2012 2.4.3 Hourly Fuel Flow Data

records for the individual units. Use the hourly heat input rates and operating times from the DH Vrecords to calculate the cumulative heat input values for each unit and report these values in unitlevel S UMMARY V ALUE D ATA records . If you use uncertified fuel flowmeter s at the unit and Equation F-21D to apportion the common pipe heat input to the in dividual units, report HFF only for the common pipe

-- do not report any HFF records showing the fuel flow to the individual

units.

For Oil Fuel Flow Records

Report an HFF for any hour in which oil is combusted as a startup fuel and fuel flow is estimate d through tank measurements.

The oil flow rate is the net fuel flow rate to the unit(s). For example, it may represent the difference between the values measured for the main supply and re

- circulating oil lines or it may represent the sum of oil flow for two fuel flowmeters measuring the same type of oil to the unit.

For oil fuel flow systems, if the fuel flow system measures mass flow rate of oil directly, leave blank the following data elements:

● Volumetric Flow Rate

● Volumetric Units of Measure Code

Fuel Code

Element Name: FuelCode

Report the type of oil or gaseous fuel combusted during the hour for the system. For oil fuels use the general fue l type codes provided in Table 2 5 below. For gaseous fuels, you may either report the type of fuel using the General Fuel Type codes (which are consistent with the codes used in the

U NIT F UEL D ATA record in the monitoring plan ) or report more specific fuel codes for the type of

gas combusted using one of the Specific Fuel Type codes. Both sets of fuel type codes are listed in

Table 26 below. The Fuel Code should match the Fuel Code in the Monitor System record associated with the Monitoring System ID.

Fuel Usage Time

Element Name: FuelUsage Time

Report the fraction of the clock hour during which the unit combusted th e specified fuel . You may use any equal incr ements from hundredths (0.01 hr) to quarters (0.25 hr) of an hour. Do not leave

this field blank.

For common pipes, report the cumulative portion of the hour during which the specified fuel was combusted in any of the units served by the common pipe, not to exceed a fuel usage time of 1.00. For example, if a common pipe serves Units 1 and 2 and both units operate for the first 24 minutes (0.40 hr) of the hour and then are both shut down, the fuel usage time is 0.40. If Unit 1 operates only for the first 24 minutes of the hour and Unit 2 operates only for the last 24 minutes of the hour, the fuel usage time is 0.40 hr plus 0.40 hr, or 0.80. If Unit 1 operates for the first 40 minutes of the hour and Unit 2 operates for the last 40 minutes of the hour, report a fuel usage time of 1.00, since for all minutes in the hour, at least one of the units operated.

Volumetric Flow Rate

Element Name: VolumetricFlowRate

For Oil Fuel Flow Records

If the fuel flow system measures the volumetric flow rate of oil, report the net volumetric flow rate, as measured, rounded to one decimal place. This value represents an hourly rate for periods in which the fuel is combusted, not a total flow for the hour. If the hourly oil fl ow rate is so small that it results in a heat input rate of 0.0 mmBtu/hr (rounded to the nearest tenth) when Equation

D- 8 is used, you may report, as a default value, the minimum oil flow rate that will give a heat input rate greater than zero. This minimum oil flow rate must be defined in the M ONITOR
D EFAULT D ATA record in the monitoring plan.

For units using Appendix D to account for SO 2 mass emissions you must report mass flow rate. I f you use a volumetric flowmeter , report the volumetric flow rate i n this field, the mass oil flow rate in the Mass Flow Rate field, and the density value used for the conversion in an H OURLY
P ARAMETER F UEL F LOW record . I f the fuel flow system measures mass flow rate of oil directly,

leave this field blank.

For Gas Fu el Flow Records

For Appendix D gas systems, the flow rate of gas is measured hourly by the fuel flowmeter system. The flow rate is the net fuel flow rate to the unit(s). For example, it may represent the sum of the gas flow rates for two fuel flowmeters measuring gas to the unit. All values must be reported in 100 standard cubic feet per hour (100 scfh) rounded to one decimal place. This value represents an hourly rate for periods in which the fuel is combusted, not a total flow for the hour.

If the h ourly gas flow rate is so small that it results in a heat input rate of 0.0 mmBtu/hr (rounded to the nearest tenth) when Equation D-6 is used, you may report, as a default value, the minimum gas flow rate that will give a heat input rate greater than zero. This minimum gas flow rate must

be defined in the M ONITOR D EFAULT D ATA record in the monitoring plan.

Mass Flow Rate
Element Name: MassFlowRate

For Oil Fuel Flow Records

Report the Mass Flow Rate of oil either measured directly by a fuel flowmeter system or calculated from the volumetric flow rate measured by a fuel flowmeter system. All values must be reported in lb/hr, rounded to one decimal place. This value represents an hourly rate for the period in which fuel is combusted, not total flow for the hour.

For units using Appendix D to account for SO 2 mass emissions , you must report mass flow rate in

order to calculate SO 2 mass emissions. Where the density of the oil is determined by the applicable ASTM procedures refere nced in Part 75, use Equation D- 3 to calculate the mass flow rate of oil (in lb/hr).

OIL = V x D
rate oil

- rate oil (Equation D-3)

Where:

OIL rate = Mass rate of oil consumed per hr (lb/hr)

V oil

- rate = Volume rate of oil consumed per hr, measured in scfh, gal/hr, barrels/hr, or

m 3 /hr (rounded to one decimal place)

D oil = Density of oil, measured in lb/scf, lb/gal, lb/barrel, or lb/m 3

However, for Subpart H units using Appendix D only for heat input determination, you may measure and report either mass flow rate or volumetric flow rate of oil. If you use volumetric flow rate and gross calorific value ( GCV ) to determine hourly heat input rate, leave this field blank.

For Gas Fuel Flow Records

Leave this field blank.

Source o f Data Mass Code

Element Name: SourceOfDataMassCode

For Oil Fuel Flow Records

Report one of the following codes to indicate the type of value reported for mass oil flow rate

. If

the mass oil flow value was calculated from a volumetric oil flow value, report code 2, regardless of what Source of Data code was reported for the volumetric oil flow. For emergency fuels where

certified fuel flowmeter s are used instead of the maximum unit f uel flow rate f or heat input, use either code 0, 1, 2, or 3 as appropriate. Do not use code 4 unless the maximum unit fuel flow rate option is used for reporting heat input for the emergency fuel.

X Operatin g Parameter Data Missing or Invalid

Y Designated Operational an d Control Equipment Parameters

w ithin Normal Limits

Z Operation Below Lowest Tested Heat Input Rate Point on the

When to Report "E"

Report "E" if the unit burned an emergency or ign ition fuel during the hour and you do not have a separate correlation curve for the emergency fuel. For these hours, report the fuel

- specific maximum potential NO

x emission rate ( MER ) in the ParameterValueForFuel field

.

When to Report "M"

When 20 calend ar quarters have elapsed since the quarter of the last Appendix E test for a particular type of fuel, without a subsequent re-test being done, the correlation curve for that fuel type has expired. From that point on (i.e., starting with the first hour after the end of the 20 thquarter), the previous correlation curve is considered invalid, and you must report the fuelspecific MER for every hour in which the fuel is combusted, until a successful re- test has been completed. Report "M" for each such hour.

When to Report "N"

Report "N" if a unit operating parameter is outside of normal limits. For example, report "N"

when excess O 2 exceeds by more than 2.0 percent the excess O 2 value recorded at the same operating heat input rate during the last NO

x emissi on rate test.

Environmental Protection Agency Emissions Reporting Instructions

-- Page 85March 07, 2012 September 19, 2012 2.4.3.1 Hourly Parameter Fuel Flow Data

Also, if one or more parameters are outside the normal limits for > 16 consecutive operating hours, a re-test is required within 30 unit operating days or 180 calendar days (whichever occurs

first -- see Appendix E, Section 2.3). Beginning with the 17th consecutive "out-of- spec " operating hour and continuing until the re-test is completed, continue to report "N" for each hour of combustion of the fuel(s) that triggered the need for the re- test.

Use missing data procedures from Appendix E for any hour in which "N" is indicated. These procedures require you to substitute the highest tested NO

x emission rate on the curve for the

fuel.

Note: If fuel flow rate and gross calorific value data are missing, use the missing data procedures in Appendix D, not Appendix E.

When to Report "U"

For units with add-on NO

x controls only. Report "U" if any parameter used to verify proper operation of the emission controls is outside of normal limits (or the control equipment is not functioning). For these hours, report the fuel- specific NO

x MER in the Parameter Value for Fuel

field

.

When to Report "W"

Report "W" if the hourly heat input rate is higher than the maximum heat input rate correlated on the curve. Use the missing data procedures in section 2.5.2.1 of Appendix E when this occurs. During your next periodic or quality assurance/quality control related testing, test under conditions more representative of your maximum potential heat rate. If possible, use the new maximum heat input rate as t he highest heat input point during the next test.

When to Report "X"

For missing or invalid excess O 2 or other operating parameter data, report "X" and report the highest NO

x emission rate on the curve for the fuel. This indicates that the hour is not demonstrated to be within the specified limits in Section 2.3 of Appendix E, but it also is not demonstrated to be outside the specified limits. (Note that the use of the "X" value is optional, you may choose instead to treat these hours as out-of-spec.) Hours marked with "N" count towards the 16 consecutive unit operating hours before retesting is required, while hours marked

with "X" do not count for this purpose. In either case, the data count against the availability of data where the unit operates wi thin the parameters. If the data availability falls below 90.0 percent, the Agency may require retesting.

When to Report "Z"

Report "Z" if the hourly heat input rate is below the lowest heat input rate. In this case it is not necessary to verify that t he operational parameters are within any specified limits. Report the

same NO

x emission rate recorded during testing at the lowest heat input rate.

Description of Data

If you have a qualifying low mass emissions (LME) unit or group of units and use a long term fuel flow system to measure oil or gas to calculate heat input, re port a L ONG T ERM F UEL F LOW

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 differe nt fuel types supply the same group of LME units, you must 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, you may represent it as a single LTOL or LTGS syste m.

LTFF Value
Element Name : LongTermFuelFlowValue

Report the total fuel flow recorded for the quarter, reporting period, or fuel flow period to zero decimal places . If you measure in units other than gallons, pounds or standard cubic feet, convert the reading to allowable units by using conversion equations.

Instructions for Using Billing Records

● If you have daily billing records, then use the daily fuel usage to apportion the fuel flow on a daily basis to hours within the ozone season or quarter beginning on the first operating day of the ozone season or quarter and ending on the last operating day of the

ozone season or quarter.

Example 1 . If a billing period starts on June 15 and ends on July 16 and the bill includes daily usage, use the daily quantities to determine which fuel was combusted during June (attributed to the second quarter) and which fuel was combusted during July (attributed to the third quarter).

● If the bill does not specify daily fuel usage, apportion fuel based on unit output, as reported in the O PERATING H OUR D ATA record.

Example 2 . If the billing period starts on June 15 and ends on July 16, and the bill only has total fuel combusted during the period, apportion the fuel into June and July based on the unit output for the billing period. Thus, if 75 percent of the unit output between June

Emissions Reporting Instructions

-- Page 90 Environmental Protection Agency2.5 Long Term Fuel Flow Data March 07, 2012 September 19, 2012

15 and July 16 occurred during June, then apportion 75 percent of the total fuel into June and 25 percent into July.

● It is the responsibility of the owner/operator to obtain all necessary billing records in time to ensure timely quarterly report submissions.

Instructions for Using Tank Drop Measurements

● For year -round reporting, measure the tank volume (the beginning and e nding LTFF measurement) within no more than 48 hours of the beginning or end of a quarter.

If you measure the level of oil in a tank on December 30 or 31 or on January 1 or 2, use this measurement (compared to the baseline value at the beginning of the quarter) to calculate the amount of fuel combusted during the quarter (even if the measurement was taken in January). Use this measurement as the baseline for determining the amount of fuel combusted during the next quarter. When apportioning heat input based on unit output only, use output from the beginning and end of the quarter, not the output corresponding to the beginning and end of the actual measurement period.

● Perform as many measurements as necessary to accurately determine fuel usage during the measurement period. The Agency recommends performing measurements before and after fuel is added to a tank unless you know the exact volume of fuel added to the tank.

● If a unit operated for only a very short period or used only a very limited amount of fuel during a quarter or reporting period so that a tank drop measurement will not yield an accurate estimate of the fuel combusted during the quarter, use the uni t' s maximum rated heat input for each hour of operation during that qu arter. Report a method of determination code ( MODC ) of "45" in the D ERIVED H OURLY V ALUE D ATA (DHV) record for Total Heat Input (HIT) for each hour.

Instructions for Using Certified Fuel Flowmeters

● When a certified Appendix D fuel flowmeter is used for long term fuel flow purposes, you are required to record hourly fuel flow rates. You must also submit M ONITORING
S YSTEM F UEL F LOW D ATA in the monitoring plan and must submit the results of all periodic fuel flowmeter quality assurance tests. However, reporting of hourly fuel flow rate information is not required. Therefore, do not report H OURLY FUEL FLOW DATA (HFF) records for LME units.

● Use the recorded hourly fuel flow rates, fuel usage times (if available) , and the density of the fuel (if needed) to determine the total mass or volume (as applicable) of each type of fuel combusted during the reporting period. Then, use Equation LM-2 or LM-3 in §75.19, as appropriate, to calculate the heat inpu t from each type of fuel combusted during the reporting period. Add together all of the reporting period heat input values for all fuels, according to Equation LM-4. Then, apportion the total heat input for thereporting period to each operating hour in the period, using Equations LM-5 through LM8A (as applicable) replacing the term "quarter" with the term "reporting period."

● When calculating the total mass or volume of fuel combusted, if hourly fuel usage times are not available, use a value of 1.00 for each operating hour in the reporting period.

● If any fuel flowmeter data are missing for any hour(s) in the reporting period, you must provide substitute data for those hours, using either: (1) the load- based missing data procedures in Appendix D (if these procedures are programmed in the Data Acquisition and Handling System ( DAHS ) ); or (2) the maximum system fuel flow rate in

M ONITORING S YSTEM F UEL F LOW D ATA record)

.

Long Term Fuel Flow UOM Code

Element Name : LongTermFuelFlowUOMCode

Report the units of measure in which you are reporting fuel flow using one of the following uppercase codes in Table 35.

Table 35 Long Term Fuel Flow UOM Code

Code Description

GAL Gallons (oil)

LB Pounds (oil)

SCF Standard Cubic Feet (gas)

Gross Calorific Val ue Element Name : GrossCalorificValue

Report the heat content or gross calorific value (GCV) o f the fuel from Table LM -5 of §75.19 or the highest GCV recorded in the previous calendar year from fuel sampling and analysis according to the procedures of Ap pendix D to Part 75. If you measure in units other than those

listed below , convert to an allowable unit by using appropriate conversion equations. Report the value to one decimal place.

GCV Units of Measure Code

Element Name : GCVUnitsofMeasureCode

Report the units of measure for GCV using one of the uppercase codes in Table 36.

Total Heat Input
Element Name : TotalHeatInput

Calculate and report the total heat input (mmBtu) measured by the LTFF system for the quarter or reporting period using the approp riate heat input formula from § 75.19 (e.g., LM

- 2, LM

- 3). Report the value to zero decimal places

.

Specific Co nsiderations

● If this system is the only LTFF system used for the unit or group of units, apportion this heat input to the unit operating hours in the quarter (or reporting period) usin g the appropriate equation in §75.19. If two or more LTFF systems ar e used during the quarter or reporting period, sum the total heat input values from all systems before apportioning heat input to the unit operating hours.

● For a single LME unit which is not part of a group of LME units, the total heat input

values for all LTFF systems used during the quarter must equal the quarterly unit heat input value reported in the S UMMARY V ALUE D ATA record.

● For a group of LME units served by one or more common pipes or tanks, you must report

both LTFF and S UMMARY V ALUE D ATA rec ords under each common pipe (or tank) ID number. For each common pipe or tank ID, the total heat input reported in the LTFF record(s) must equal the quarterly heat input reported in the S UMMARY V ALUE D ATA
record.

● For any hour during which the unit is burning a secondary fuel that is not measured by a long term fuel flow system, you m ust calculate the total heat input for the hour using the maximum rated hourly heat input rate for the unit. Report an MODC of " 45 " in the DHV record for (HIT) for the hour.

● If a unit (or group of units linked to a common pipe) using LTFF to determine heat input burns fuel, but does not generate any load during the reporting period, apportion the total heat input based on operating time instead of load using the appropr iate equation in §75.19.
