1 MEMORANDUM
TO: Jim Eddinger, U.S. Environmental Protection Agency, OAQPS
FROM: Amanda Singleton and Graham Gibson, ERG
DATE: April, 2010
SUBJECT: Standardization of Reported Data from the Questionnaire for Boilers, Process Heaters, Incinerators an d Other Combustion Units

1.0 INTRODUCTION

This memorandum describes the processes used to standardize fuel type, emission test data, continuous emission monitor (CEM) data a nd other data reported by industry in the 2008 Questionnaire for Boilers, Process Heaters, Incinerators and Other Combustion Units 1 (ICR No. 2286.01, OMB Control No. 2060-0616, EPA Form No. 5900-122) and the 2009 Test Plan for Industrial, Commercial, and Institu tional Boilers and Process Heaters 2 (ICR No. 2286.02, OMB Control No. 2060-0616, EPA Form No. 5900-122). ERG developed a comprehensive survey results database of all data reported by industry, as well as a consolidated emissions database. A data dictionary and description of all the fields contained in the database are summarized in other
memoranda 3 . This memorandum discusses only those data fields which required standardization, including (but not limited to) emission values, design capacity values, fu el types and control devices. This memorandum also explains the methodologies and any c onstants and conversion
factors that were used to st andardize these data fields.

Various types of reported qualitative and qua ntitative data were standardized by creating
additional data fields in the ERG databases. Thes e fields were beneficial because they allowed manipulation of the raw data while maintaining a visual copy of the reported data. Further,2 knowing the reported data present alongside the ma nipulated data eased the process of quality assurance (QA) on the standardized fields.

Industry reported data in many different fo rmats, including a variety of units of measurement for pollutant emission values and nome nclature differences for a single fuel type. In order to make these categorizations, it was necessary to standardi ze this wide range of reported data.

This memorandum is divided into the following sections:

.3 2.0 QUALITATIVE DATA STANDARDIZATIONS

Reported fuel types and control devices we re standardized in order to categorize combustion units at separate facilities. E ach combustion unit was also assigned a specific classification based on its physical design to furt her aid in the categoriz ations. The processes used and assumptions made in standardizing these re ported data are discussed within this section.

2.1 Fuel Types

Fuel type is reported in 8 of the 23 data tables in the ERG databases. In order to assign combustion units to a fuel category and analyze da ta across different fuel types, these reported
fuels needed to be standardized across all data tabl es where fuel type is used to characterize the
unit. Table 1 shows each mention of fuel in the da tabase where a corre sponding standardized fuel field was generated. The re ported design capacity fuels were not standardized because they may not necessarily represent the fuels r outinely combusted in the combustion units.

NRC_Fuel Common NRC_Fuel

Data: Non-Fossil Fuels NonFossilFuel Common Fuel4 A “common” fuel field was cr eated corresponding to each re ported fuel type in the database. In order to assign a common fuel t ype to each unique fuel reported, a table called
LOOKUP: Common Fuels was created to map each reported fuel to a standardized fuel spelling and category. The level of detail within the common fuel categories were based on fuel categories provided in Appendix C of the Survey Overview Document 2 . If the reported fuel did not match any of the corresponding fuel categorie s in Appendix C, a new common fuel category
was created.

Fuels were occasionally reported as a combina tion within a single re cord. Each reported
fuel in the mixture was standardized to the form at listed in Appendix C of the Survey Overview
Document 2 , separated by “and” or “/” in the standardiz ed fuel field. For example, a reported fuel of “#2 Fuel Oil, kerosene” was standardized to “No. 2 Distillate and Kerosene” or “No. 2 Distillate/Kerosene.” Combination fuels that app eared in a single data record were also included
the LOOKUP: Common Fuels table.

Survey respondents were asked to select a fu el from a series of drop-down lists in the Microsoft ® Excel spreadsheet templates. These te mplates also allowed industry to select “other fuel” and enter a description of the type of fuel they combust. In these ca ses, the description was what was reported as the fuel t ype in the database. For data reported in the 2008 questionnaire,
when an actual fuel was selected from the dr op down menu and comments were also entered in the other fuel type description field, the comments were reported as the fuel in the database instead of the fuel type selected from the drop- down list. In these cases, the original survey response template files were reviewed and the intended fuels were manually entered into the reported fuel fields of the database and the comm ents moved to the descri ption field. Then, the standardized fuel fields were update d using the format specified in the LOOKUP: Common
Fuels table.5 2.2 Air Pollution Control Devices

Add-on air pollution control devices are reported in 4 of the 23 data tables. In order to categorize and compare the current state of cont rols installed for various types of combustion units these reported devices need to be standardized across all data tables where a control device
used to characterize the data cont ained in a particular record. Table 2 shows each mention of
control device in the database where a corres ponding standardized control device field was generated.

Table 2 - Standardized Control Device Fields
Table Reported Control Device Field Standardized Control Device Field Data: CEMS Backgrnd TypControl Standardized TypControl

ControlDevice Standardized ControlDevice Data: Control Device PriorDevice Standardized PriorDevice
Data: EmissionsTest

Background Info ControlDevice Standardized ControlDevice

In order to assign a standardized control de vice to each unique control reported, a table
called LOOKUP: Control Devices was created to map each reported control device to a standardized control device spel ling and category. The standardiz ed control types were based on the list of control devices provided in the drop down lists in the Survey Answer Key 4 . If the reported fuel did not match any of the correspon ding control devices in the Answer Key, a new control device category was added to the LOOKUP: Control Devices table.

In the Data: CEMS Backgrnd and Data: EmissionsTest Background Info tables, the reported control devices were ofte n reported as “As listed in ques tion II.B.3.a1” or “As listed in question II.B.3.a6.” Both are re ferences to the entries for th at specific combustor in the Data:
Control Device table. The former is a reference to the “ControlDevice” fi eld whereas the latter
is a reference to the “PriorDevi ce” field. In those instances, the standardized control device field was populated with the standardized cont rol device data to which it referred.6 Occasionally, combinations of control de vices were entered when comments were entered as a result of selecting “other control device” from the drop-down list of controls in the Microsoft ® Excel template files. In these instan ces, each reported control device in the mixture was standardized, with individual control devices separated by “and” or “/” in the standardized field. For example, if a facility reported a cont rol device combination of “Flue gas recirculation/ low now burner”, this was standa rdized to “Low NOx Burners and Flue Gas Recirculation” or
“Low NOx Burners/Flue Gas Recirculation.”

Survey respondents were asked to select a cont rol device from a series of drop-down lists in the Microsoft ® Excel spreadsheet templates. These templates also allowed industry to select
“other control device” and enter a description of the control devi ce installed on the unit. In these cases, the description was what wa s reported as the fuel type in the database. For data reported in the 2008 questionnaire, when a specific control device was selected fr om the drop down menu
and comments were also entered in the other fu el type description field, the comments were reported as the control device in the database instead of the c ontrol device selected from the drop-down list. In these cases, th e original survey response template files were reviewed and the
intended control devices were manu ally entered into the reported control device fields of the database and the comments moved to the descripti on field. Then, the standardized control device fields were updated using th e format specified in the LOOKUP: Control Devices table.

2.3 Unit Classifications

The 2008 questionnaire collected data on several types of combustion un its. In order to analyze data on a particular subset of combusti on units, each unit was assigned to a classification of “Boiler,” “Process Heater” or “Other.” There was no clear and direct question within the questionnaire itself that asked whether a combus tion unit was a boiler, process heater or other unit. However there were a series of questions th at, if answered correctly or answered at all, would give enough information to deduce the type of unit. Table 3 shows the hierarchy used to classify all reported combustion units based on these indirect questionnaire questions.7 Table 3 - Combustor Classification Hierarchy Step Criteria Classification
If the facility selected a boile r design for the combustion unit (questions II.B.1.K and II.B.1.L of the Answer Key 4 ). Boiler 1 If the facility selected a process heater design for the combustion unit (question II.B.1.M of the Answer Key 4 ). Process Heater If the primary use of the combustion device was listed as steam generation and not also waste incineration (question II.B.1.I of the Answer Key 4 ). Boiler
2 If the primary use of the combustion device was listed as process heat and not also waste incineration or steam generation (question II.B .1.I of the Answer Key 4 ). Process Heater

If the fuel combusted was listed as being directly fed to a boiler (question II.C.2.B of the Answer Key 4 ). Boiler
If the fuel combusted was listed as being directly fed to a process heater (question II. C.2.B of the Answer Key 4 ). Process Heater 3
If the fuel combusted was listed as being directly fed to any other type of unit (question II.C.2.B of the Answer Key 4 ). Other

4 If the unit noted any cleaning/reconditioning or inspection of a feed water system (question II.B.3.C of the Answer Key 4 ). Boiler

5 If modifications to a unit’s c ontrol device(s) were made in order to comply with the now vacated 40 CFR 63 Subpart DDDDD (question II.B.3.A.4 of the Answer Key 4 ). Boiler

6 If the facility selected an other combustor type design for the combustion unit (question II.B.1.N of the Answer Key 4 ). Other

7 If the facility-specified combustor ID contained any reference to the unit being a bo iler (for example, a combustor ID of “Boiler 1” would fit this description). Boiler

8 All remaining units. Other

If a unit met more than one of the criteria listed above, it was classified based on which
criteria was listed first in the table. For exam ple, if a combustion unit’s primary use was steam generation (step 2) but also report ed feeding fuel directly to a process heater (step 3), the unit
was classified as a boiler and not a process heater.

After the eight steps in Table 3 were completed the data were reviewed to ensure that, even if the unit was a boiler, all assigned clas sifications were logical. The structure of the questionnaire itself allowed those reporting data to enter informati on about a boiler into a section about process heater designs, or vice versa. If the facility-assigned unit ID given to a combustion8 unit did not logically match the information th ey provided, then changes were made to the classification of the unit. For example, if a facility submitted data for a combustion unit named “Boiler 1,” but completed only sections dealing with process heaters, the combustion unit would have been classified as a process heater. In th is case, the classification would have been changed from process heater to boiler. For all similar in stances, the classifications were investigated and corrected using the same method.

3.0 STANDARDIZATION OF EMISSION DATA

Emission data were reported in the data tabl es in the consolidated emissions database
entitled Data: EmissionsTest , Data: CEMS, and Data: CO and THC CEMS . All of the emission data were standardized according to the procedures listed in this section.

3.1 Standardizations of Reported Emission Test and CEMS Data

The reported emissions data from emission test results and CEMS were standardized in order to provide a common basis for analyzi ng and comparing emission data from various potential boiler and process heater subcateg ories. The automated conversion equations, constants, and assumptions used to standardize emission data are discussed within this section.

In order to allow for reporting of both non- detect data (with detection limits) and detectable emission data, all emission data were imported in a text field format. Numeric fields mirroring the contents of this text field were cr eated in order to apply mathematical operations on the emission data, and the reported detection li mits for non-detect emissions data. These data were reported as textual data due to the format in which non-detect da ta was reported; those completing the survey were asked to enter the det ection limit for that pollutant and test enclosed by brackets. Any reported data in this format was deemed non-detect and the value inside the
brackets was used as the detection limit. Non-det ect data was also reported in other formats, so any reported data that included any text other than a numeric value was considered to be nondetect. For example, if the reported emission va lue was “ND 0.5” then the value was assumed to
be non-detect and 0.5 was used as the detection limit. The format of the Questionnaire and Test9 Plan templates did not allow fo r monitoring data to be reporte d as non-detect values, so all reported data was assumed to be above detection limits.

Next, the units of measure were reviewed to identify any gaps or in consistencies in the reported units of measure. Sometimes the repor ted emission value included both the units and the emission value in the emission field, resulti ng in no units of measure reported in the emission unit column. In these cases, these units of m easure were separated from the emission value and the “Standardized Pollutant_Units” field was upd ated to include the intended units. For example, if the reported emission value was “ 10 ppm” and the reported emission value unit was null, the “Standardized Pollutant_Units” field was updated to “ppm” wh ile the “Standardized Pollutant_Value” field was updated to “10.”

Some combustion units reporte d an emission value but did not report any units of measurement corresponding to that value. These data points were compared to other data points from the same facility, combustor and pollutant. If there was additional data with reported units
of measure and the value without units of measure was of the same order of magnitude, it was
assumed that the units were consistent. Fo r example, if a combustion unit reported CO emissions to be “10 ppm,” “14 ppm,” and “12”, it was assumed that the “12” was intended to be “12 ppm.” If the reported emission value without any units of measure was not within the same order of magnitude, no units of measure were assi gned to the data points and those values were
not standardized.

After both a numeric emission data point and a reported unit of measure had been assigned and reviewed, the emissions were standa rdized using a two-step process: First, the
numeric emission values were converted to un its of either pounds per million British Thermal Units (lb/MMBtu) or a standard ized concentration, depending on the base units of measure
associated with the emission data. If units were reported in a concentration format these
concentrations needed to be standardized before proceeding to the second step of the standardization process. Generally, pollutant s that are emitted as gases (i.e., organic and inorganic hazardous air pollutants) are reported on a relative basis, such as volume of pollutant per volume of stack gas. Pollutants that are emitt ed as solids or particulate matter are reported10 on an absolute basis, such as mass of pollutant per volume of stack gas. Table 4 shows the units of measure resulting from step 1 of the emission data conversions.

A comprehensive list of all reported emissi on units was generated and a unit conversion equation was developed for each individual reporte d unit. These equations convert the numeric emission test values into the preferred units of measure. The database table LOOKUP: Unit
Conversions was created to assign each reported unit of measure to a conversion equation ID in
order to automate the data standa rdization process. Each equation ID is labeled according to the type of conversion it represents. Table 5 shows the equation ID prefix es given to the different types of conversion equations.11 Table 5 - Conversion Equation ID Prefixes Equation Type ID Prefix
Concentration Conversions CEq

Units of Measure Not Able to be Converted -

Reported units of measure that were not in concentration, mass per time or mass per heat input format were not converted. Alt hough those units are also located in the LOOKUP: Unit
Conversions table, they were assigned an “NED” Un it Format, or “No Equation Developed.” A complete list of all these conve rsion equations can be found in Table B-1 of Appendix B

.

3.2 Standardizations of Other Emission Test Parameters

As shown in Appendix B , the conversion factor needed to standardize emission test data may be a numeric multiplier, based on a series of constants to convert from one unit of measure to another. Alternately, the conversion factor may require other parameters (e.g., fuel input, exhaust flowrate, oxygen correction) during the test run to be in corporated into the conversion factor. If these parameters are used in a conversion equation they must also be standardized to
ensure accurate conversion of th e emission test data. Additional fields were created for the standardization of each additional conversion parameter. Only those values that were
standardized will have a value in the standardized field. If the data could not be standardized,
the standardized field was left as a null value. Table 6 shows the types of emission test and CEM parameters that needed standardization.12 Table 6 - Additional St andardized Parameters Data Category Standardized Units of Measure
Total Heat Input MMBtu/hr
Fuel Input Rate MMBtu/hr
Amount of Oxygen in Process Exhaust %, O 2
Amount of Moisture in Process Exhaust %, H 2 O

Exhaust Flowrate dscfm
Exhaust Temperature °F

Molecular Weight g/g-mol

For each of the parameters discussed belo w, a numeric field was created to apply necessary mathematical operations in order to sta ndardize the parameter to the preferred units of measure. These numeric fields mirrored the origin al text fields containi ng the reported values for each parameter. However, the database would not automatically convert the numeric fields if the data was not numeric. In these cases, the parameters needed to be cleaned up and manually entered in the numeric fields. For example, if a reported numeric value used a comma in place of a decimal point, that value would not be auto matically converted; so, the comma was replaced with a decimal and the numeric value was manually entered.

3.2.1 Heat and Fuel Input Rates Some emission data conversion equations requir ed the heat input or fuel input during the
test to be standardized to MMBtu/hr. If emi ssions were reported as a pollutant mass per unit of time, the total reported heat input during the te st run was the preferred conversion parameter. However, if a facility did not report a total heat input value and instead repo rted fuel input rates, the sum of all standardized fuel input rates we re used to convert the emission test values.

Some emission data were reported as a mass of emissions per mass of fuel combusted. In order to standardize these reported values into units of lb/MMBtu, the average higher heating13 value (HHV) reported in the questionnaire for each fuel listed as an input was needed to convert
the emission data. The standardizati on of all HHV values is discussed in Section 5.0 . If a combination of fuels was reported, an equally weighted mixture was assumed and the HHV for each constituent fuel was averaged. Sometimes the fuel reported with the design capacity units was a generic “fuel oil” or “coal.” Any unspecifi ed specification of fuel oil was assumed to be
No. 2 Distillate because it is the most common specification of oil reported to be combusted in the questionnaire. An unspecified type of coal was assigned the HHV of bituminous coal because it was the most common type of coal report ed to be combusted in the questionnaire. All types of wood were assumed to have the same HHV as was assumed in the Memorandum from Jack Johnson, ERG, to Fred Porter, US EPA 5 . A list of HHV for specific fuel types can be found
in Table B-2 of Appendix B

.

The conversions used to standardize the fuel and heat input rates ar e identical to those used to standardize the design capacity of each combustion unit (as described in Section 4.0 ). A
list of these conversions can be found in Table B-3 of Appendix B

.

3.2.2 Exhaust Oxygen and Moisture Content
Some emission data conversions required the amount of oxygen (O 2 ) and/or moisture present in the exhaust stream to be standardi zed to a percent. The 2008 Combustion Survey and 2009 Test Plan requested O 2 and moisture be reported as percent and it was assumed that all reported values were already in these units sinc e the survey respondent could not specify other
units of measure. Values such as “0.05” we re assumed to be “0.05%” and not “5%” since the survey specifically asked for units in percent format.

Since a percentage cannot be greater than 100, the O 2 and moisture contents were reviewed to ensure that no repor ted data were above that threshol d. If a facility did not submit
O 2 or moisture data, the standardized fi elds were not populated with anything. O 2 data was only a requirement when reporting carbon monoxide data in the 2008 Questionnaire. Oxygen percentages were requested for all pollutants in the 2009 Test Pl an. If the reported units of measure required an O 2 concentration for standardization, an O 2 concentration of zero percent14 was used in the conversion calcula tion if a percentage was not reported and if the pollutant was
not carbon monoxide.

3.2.3 Exhaust Flowrate Some emission conversions required the exhaust stream flowrate to be standardized to dry standard cubic feet per minute (dscfm). A ny reported unit of measur e that listed contained
the letter “D” was assumed to be an abbreviati on for “dry.” Similarly, any reported unit of
measure that listed an “S” was assumed to be an abbreviation for “standar d.” If a unit reported an “S” but no “D” (such as “scfm,” an acronym fo r “standard cubic feet per minute”), the units were assumed to be at dry standa rd conditions. A list of all exha ust flowrate conversions can be
found in Table B-4 of Appendix B

.

3.2.4 Exhaust Temperature Some emission conversions required the exhaust stream temperature to be standardized to degrees Fahrenheit (°F). Any standardized temperature greater than 2,000 °F was compared against the other temperatures repor ted at that facility in the attemp t to find typographical errors. If the reported temperature was subject to a typo graphical error, the order of magnitude for the reported and standardized temperature values wa s reduced in order to maintain consistency between all data points at that facility. For example, if a f acility reported te mperatures of “356.746 °F,” “359.617 °F” and “364223 °F,” the latt er was changed to “364.223 °F.” A list of all exhaust temperature conversions can be found in Table B-5 of Appendix B

.

3.2.5 Molecular Weights Some emission conversions required the molecu lar weights of specific pollutants in order
to convert the emissions test data. The database table LOOKUP: Pollutant Molecular Weights assigns a molecular weight, in grams per gram-mole (g/g-mol), for all pollutants specified in the survey. Since polycyclic aromatic hydrocarbon (PAH) data is reported cumulatively for all associated components, the molecular weights of the components of each PAH group were summed to get a cumulative molecular weight. Table 7 shows the compounds that make up the PAH groups and the groupings to which they belong.15 Table 7 - PAH Constituent Compounds Compound 7-PAH 15-PAH 16-PAH

Fluorene X X

Phenanthrene X X

Anthracene X X

Pyrene X X
Benzo(g,h,i)perylene X X

Dibenzofuran

Some facilities did not test for specific PAH compounds in the PAH groupings. This was reflected as a written note accompanying the em ission test data, telling which constituent compounds were not included in the emission value. In these instances, the reported pollutant16 was changed to reflect the corresponding P AH group, minus the selective compounds. For example, if the note specified that the test was for all constituents of 7-PAH except for chrysene, the pollutant field was changed to “7-PAH not chrysene.” Additional molecular weights were generated for these altered PAH groups and were used in the conversions where applicable.

After these parameters were standardized, th ey could be used in any of the conversion equations applied to the emission data and emission limits. Figures 1-3 show examples of
emission test data and emission mo nitoring data linked to the tabl es which hold these parameters.

Figure 2 - ET Conversion Field Linkage17 Figure 3 –ET Conversion Field Linkage, 2

3.3 Applying and Tracking Em ission Conversion Equations

Once all of the reported emission and associat ed parameter data were standardized a series of update queries were programmed to make the conversions. Thes e queries converted the numeric emissions data fields ( by multiplying by the conversion fact or assigned to each base unit
in the LOOKUP: Unit Conversions table) and updated the standa rdized emission unit of measure fields with the appropriate unit. Figures 4-5 show examples of fields in the Data: EmissionsTest
and Data: CEMS tables, respectively, that were conve rted using these conversion equations.

Figure 4 – ET Fields Standardized via Conversion Queries

Figure 5 - CEMS Fields Standardized via Conversion Queries

Additionally, these queries tagge d each of the records conve rted in the emission data
tables with the conversion ID that was used to convert the reported data. If a record was missing18 any of the test parameters necessary to run th e conversion, or if the re ported unit of measure could not be standardized, the que ries tagged the record with a not e to indicate why the data was
not standardized in lieu of assi gning the record a conversion ID. For example, if the reported data was in units of pounds per hour, but the faci lity did not provide heat and/or fuel input information during for the specific test, the “Conversion Eq Used” field would have been populated with “Not Able to Convert – THI Value.”

This programmed update query approach to data standardization was beneficial for several reasons: First, these que ries did not manipulate the raw survey data in any way. The presence of any conversion errors would not resu lt in the loss of data as the “Standardized Pollutant_Value” field could easily be repopulatedand reconverted based on the original textbased data field. As previously mentioned, a ny typographical errors were corrected in the reported data fields, so repopulat ing the standardized field woul d not require manual entry each time. Secondly, updating the “Standardized Poll utant_Units” fields as part of each query allowed the programmer and reviewer to review any records that coul d not be converted. Tagging each record with its associ ated conversion ID provided revi ewers with an opportunity to
isolate and check the converted values associated with each conversion ID.

After all emission conversion update queries were completed on the Data: EmissionsTest data table, each emission record in the data table would be standard ized to one of the units listed
in Table 4 or the record would contain a note that th e data could not be converted. Similarly,
each emission record in the Data: CEMS and Data: CO and THC CEMS data tables was
standardized to one of the units listed in Table 4 or the record would cont ain a note that the data
could not be converted.

The standardized numeric fields were inve stigated to ensure that the conversions themselves had run correctly. A ny blatantly obvious er rors in conversions were corrected. The range of numeric values at both th e facility level and for the entire database were investigated to find questionable data points. If a facility had standardized values that differed by orders of magnitude, its individual data point s were investigated further to determine if they were subject to typographical errors. These erro rs were usually a result of the facility not entering a decimal19 with the reported values. For example, if a facility reported “5.67,” “5.84” and “574” the latter value is obviously a typographical error and was changed to “5.74.” For all remaining questionable data values, the numeric value was s till standardized but a no te was entered stating that the value was inconceivable and is not used in any further analyses.

3.4 Applying Fuel Factors (F-fa ctors) to Emission Data

After the emission data were st andardized as described in Sections 3.1 to 3.3 above, step two of the emission data processi ng was to convert the data into the preferred standard units of measure used in the development of National Emission Standards for Hazardous Air Pollutants at Industrial, Commercial , and Institutional Boilers and Process Heaters. Table 8 shows the preferred units of measure for sp ecific pollutants following F-Fact or conversions. In order to convert the data to these units of measure, an F- factor was necessary to re late exhaust volumes to fuel energy inputs.20 Table 8 - Standardized Unit s of Measure for the F-Fact or Standardization Process
Pollutant Resulting Units of Measure After FFactor Conversions CO, NOx, SO 2 , Total Hydrocarbons (as propane), Formaldehyde ppm @ 3% O 2

Total Mass Dioxins/Furans ng/dscm @ 7% O 2

Toxic Equivalent (TEQ) Dioxins/Furans TEQ ng/dscm @ 7% O 2

All Other Pollutants lb/MMBtu

F-Factors themselves are fuel-specific. A unique F-Factor was assigned to each emission test based on the fuel reported during the test, an d that value was used in the standardization of the reported data. A list of a ll F-Factors used in converting em ission test and CEM data (and the sources from which the F-Factors were found) can be found in the LOOKUP: F-Factors
database table.

Three data sources were used to develop F-Factors. The primary source was the EPA Method 19 table, which included F-Factors for wood, bark, tire derived fuel, petroleum coke, gaseous fuel and oil (crude, dist illate and residual). It was assumed that the wood F-Factor applied to all types of wood. Fu els not present in the Method 19 table were located in alternate sources, including the emission test database developed fo r the Industrial Combustion Coordinated Rulemaking (ICCR) and the vacate d boiler MACT and an EPRI report containing
field demonstrations from biodiesel. 7,8,9 All data sources are specified in the LOOKUP: FFactors table of the Emissions Database for Boilers and Pro cess Heaters Contai ning Stack Test, CEM, & Fuel Analysis Data Reported under ICR No. 2286.01 & ICR No. 2286.03 (version 5) . If an emission test reported combusting more than on e type of fuel during the test, an average of the F-Factors for each fuel type in the mix were used. If an emission test reported a fuel for which no F-Factor could be found, the data po ints corresponding to that fuel were not standardized in this step. Sim ilarly, if an emission test reporte d a fuel combination and one or
more of the constituent fuels had no F-Factor assigned, only the fuels wi th known F-Factors were averaged to get the final value.21 Once each emission test or CEM record was a ssigned an F-Factor, these F-factors were used as a parameter in the ten F-factor equations beginning with the prefix “FF” that are listed in
the LOOKUP: Unit Conversions table. These equations can also be found in Table B-1 of Appendix B . These F-factor equations were applied in a series of programmed update queries, similar to the update discussion in Section 3.3 above. These queries updated the final
standardized emission values and units of meas ure and tagged each record with the F-factor equation used to convert the data. If there wa s no F-factor available for the fuels corresponding to the emission data, the queries tagged the reco rd with a note to indicate why the data was not standardized in lieu of assigni ng the record a conversion ID. Figures 7-8 show which fields in
the Data: EmissionsTest and Data: CEMStables, respectively, were converted using these FFactor conversion equations.

Figure 7 - ET Fields Standardized via F-Factor Conversion Queries

Figure 8 - CEMS Fields Standardized via F-Factor Conversion Queries

After all F-factor update queries were completed on the Data: EmissionsTest data table,
each emission record in the data table would be standardized to one of the units listed in Table 8
or the record would contain a not e that the data could not be converted. After all F-Factor conversion update queries were completed on the Data: CEMS data table, each emission record in the table corresponding to CO and PM data were standardized to one of the units listed in
Table 8 or the record would contain a note th at the data could not be converted.

The values generated from the F-Factor convers ions were investigated to ensure that the conversions themselves had run correctly. Data ranges were also investigated as mentioned in
Section 3.3 above. Reported data that ended up not converted by the F-Factor queries were investigated to make sure that the data pertaine d to an emission test burning a fuel which was not assigned an F-Factor.22 3.5 Total Metals Emissions

For each specific emission test for which data was reported and standardized for selected metallic HAP, a total metals emission va lue was created for each test run. Table 9 shows the
metallic HAP that were selected to create total metals emission values.

Table 9 – Metallic HAP
Metallic HAP
Antimony (Sb) Cobalt (Co)

Arsenic (As) Lead (Pb)
Beryllium (Be) Manganese (Mn)
Cadmium (Cd) Nickel (Ni)
Chromium (Cr) Selenium (Se)

Using data from the Data: EmissionsTest table, the Data: Total Metals Emissions table was generated to contain the calculated total metals emissions values. For each unique emission test, a total metals value was calculated for each test run if standardized da ta was available for all
metallic HAP listed in Table 9 . These values were generated by summing the standardized
emission values for each metal. Emissions data were not requested for antimony and cobalt in the 2008 Questionnaire, so only data from the 2009 Test Plan were used to calculate total metals
emission values.

3.6 Total Mass Dioxin/Furan Emissions

The 2009 Test Plan requested emission data for dioxin/furans on a mass basis. Data were
submitted as both a total dioxin/furan emission value, as well as emissions for specific congeners. A total dioxin/furan emission value was generated on a total mass basis for each combustion unit that reported dioxi n/furan data. If a total dioxin /furan value was reported, it was
selected as the total mass value for that combusti on unit. If no total mass value was reported, but23 data were reported for individual congeners, th e sum of the emission values for each congener
was used as the total mass value. Table 10 shows the individual congeners for which data were reported.

It was assumed that if data was reported fo r a subset of all conge ners, there were zero emissions of the congeners with missing data. If a facility reported a total mass dioxin/furan
value and data for the individual congeners, the reported total mass value was selected. A table24 named Data: Total PCDD/PCDF Emissions (TEQ & Total Mass) was generated to hold the total
mass values for each combustion unit. Total mass va lues were calculated on the test run level for each unique emission test.

For each combustion unit that reported indi vidual congener data, a toxic equivalent (TEQ) value was calculated using the World Health Organization 2005 Toxic Equivalency Factors (TEF) 5 . These factors standardize the emission values of individual congeners to a health-based comparison of the congener 2,3,7,8-TCDD. For example, the TEF for 1,2,3,4,7,8 HxCDD is 0.1, meaning that 1 gr am of 1,2,3,4,7,8 HxCDD has the sa me adverse health potential as 0.1 gram of 2,3,7,8-TCDD. A lis t of all TEF can be found in Table B-10 of Appendix B and
in the LOOKUP: Toxic Equivalency Factors database table.

The emission values for each congener were multiplied by the TEQ factor in order to obtain a TEQ emission value for each congener. Then, the TEQ values were summed for each test run for each specific emission test . The TEQ values were appended to the Data: Total PCDD/PCDF Emissions (TEQ & Total Mass) , located in the same r ecord as the corresponding
total mass value calculated for the combustion un it’s emission test. Since some combustion units reported a total mass value but not individual cong ener data, a TEQ value could not be calculated
for each unit with total mass data.

4.0 STANDARDIZATION OF DESIGN CAPACITIES

The reported design capacity of each boiler and process heater was standardized to units of million British thermal units per hour (MMB tu/hr) in order to provide a common basis for analyzing and comparing data from various sizes of boilers and process heaters. The automated conversion equations, constants, and assumpti ons used to standardize emission data are
discussed within this section.

First, two data fields calle d “Standardized Capacity” and “Standardized CapacityUnit”
were created in the Data: Unit Design/Operation table to hold the sta ndardized design capacity
data. These fields were created so as to not overwrite the data originally reporte d data during the25 standardization process. Additi onally, since the reported design capacity was a text-based field the “Standardized Capacity” field was created as a numeric field. This allowed mathematical operations to be applied to the reported design capacities in order to standardize the parameter to the preferred units of measure. Next, a list was created to identify unique units of measure reported with each design capacity. This list was reviewed to identify and update design capacities without reported units of measure. Missing units of meas ure were corrected in one of three ways:

 If the reported design capacity value included the units of measure and the reported “CapacityUnit” field was null, the “Standardized CapacityUnit” field was updated to include the intended units. For example, if the reported design capacity was listed as “100 MMBtu/hr” a nd the reported design capacity unit was null, the “Standardized CapacityUnit” fi eld was updated to “MMBtu/hr” while the “Standardized Capacity” fi eld was updated to “100.”

 For units that reported a design capacity value but did not re port any units, the design capacity was compared to design cap acities from other combustion units at the same facility. If additional combusto rs of a similar size were reported with
units of measure and the value was of the same order of magnitude, it was
assumed that the units were consistent. For example, if Boiler 1 and Boiler 2 were located at the same facility, and Bo iler 1 reported a design capacity of “100 MMBtu/hr” while Boiler 2 reported a desi gn capacity of “120,” and did not report any units, it was assumed that the “120” was intended to be “120 MMBtu/hr.” In this case, the “Standardized Capacity Unit” field was updated to “MMBtu/hr” while the “Standardized Capacity” field wa s updated to “120.” If no distinction could be made for the unit with missing units of measure, the “Standardized CapacityUnit” field was updated to “unknown.”

 If the user selected units of measure fo r the design capacity from the survey drop down menu and also provided a note about these units in the field reserved for collecting “other” units of measure, this description was reported as the units of26 measure in the database. In these case s original Microsoft ® Excel templates
were reviewed and the correct units of m easure were entered in the standardized design capacity and design capacity unit fields.

After these units of measure were corre cted, a lookup table was created in the comprehensive survey results database to map all of the unique reported units of measure to their appropriate conversion equations and conversion factors. This lookup table is entitled LOOKUP: Design Capacity Conversions . The aim of this lookup table was to create a method for automatically converting large quantities of design capacity values. A list of all design capacity and heat input convers ion factors can be found in Table B-3 of Appendix B

.

As shown in Appendix B , the conversion factor needed to standardize design capacities may be a numeric multiplier, based on a series of constants and assumed efficiencies to convert
from one unit of measure to another. Alternat ely, the conversion factor for design capacities expressed in terms of fuel input rates may require the fuel high er heating value (HHV) in order to standardize the design capacit y. If these parameters are calle d into a conversion equation they
must also be standardized to ensure accura te conversion of the emission test data.

If a higher heating value (HHV) was necessa ry for a design capacity conversions, the type of fuel was determined based on the fuel re ported to be associated w ith the design capacity.
The standardization of all HHV values is discussed in Section 5.0 . Sometimes the fuel reported with the design capacity units was a generic “fuel oil” or “coal.” Any unspecified specification
of fuel oil was assumed to be No. 2 Distillate because it is the most common specification of oil reported to be combusted in the questionnaire. An unspecified type of coal was assigned the
HHV of bituminous coal because it was the most co mmon type of coal reported to be combusted in the 2008 Questionnaire. All types of wood were assumed to have the same HHV as was assumed in the Memorandum from Jack Johnson, ERG, to Fred Porter, US EPA 5 . A list of HHV for specific fuel types can be found in Table B-2 of Appendix B

.

After all of the reported desi gn capacity units and HHV were standardized, a series of update queries were programmed to make the c onversions. These queries converted the numeric27 design capacities by multiplying by the conversion factor assigned to each base unit in the LOOKUP: Design Capacity Conversions table, and incorporating the appropriate HHV into the conversion, when necessary. For design capac ities that could not be converted, the “Standardized CapacityUnit” field was updated to “unknown.”

Design capacities for multiple units at the same facility were compared in order to find errors in the conversions. The total ranges of converted design capacities for each group of reported units of measure were inve stigated to ensure that there we re no questionable data points. Standardized design capacities greater than 1,800 MMBtu/hr were deemed illogical and the “Standardized CapacityUnit” field was updated to “unknown” for those combustion units.

5.0 STANDARDIZATION OF FUEL ANALYSIS DATA

Fuel analysis data were sta ndardized in order to impleme nt emission data conversions and develop emission factors for mercury, HCl, a nd metallic HAP at uncontrolled liquid fuel units. The automated conversion equations, cons tants, and assumptions used to standardize
emission data are discussed within this section.

5.1 Standardization of Higher Heating Values

Higher heating values (HHV) were a requi red parameter for some emission data conversion equations. In order to st andardize HHV, two data fields called “ParameterValueNumeric” (a numeric field) an d “CorrectedParameter_Units” were created in
the Data: Fuel Analysis table to hold the standardized HHV. These fields were created so as to not overwrite the data originally reported data during the standa rdization process. Additionally, since the reported HHV were in a text-based field the “ParameterValueNumeric” field was
created as a numeric field to allow mathematical operations to be applie d to the reported HHV in order to standardize the parameter to the prefer red units of measure. Sometimes the reported
HHV included both the units of measure and the valu e in the HHV field, resulting in no units of measure reported in the HHV unit column. In thes e cases, these units of measure were separated
from the HHV and the “Standardized Paramete r _Units” field was updated to include the28 intended units. Table 11 shows the preferred units for all HHV values based on the state of matter of the corresponding fuel.

Table 11 – Preferred Units of Measure for HHV Fuel State of Matter HHV Unit

Solid Btu/lb
Liquid Btu/gal

Gaseous Btu/scf

If HHV were reported in terms of Btu/gallon, a density of each of the fuels was needed to develop an emission factor with units of lb/MMBtu. Table B-6 of Appendix B shows a list of all the liquid fuel densities and assumptions used to estimate de nsities in order to convert HHV from Btu/gallon into Btu/lb.

After these units of measure were corre cted, a lookup table was created in the comprehensive survey results database to map all of the unique reported units of measure to their appropriate conversion equations and conversion factors. This lookup table is entitled LOOKUP: Fuel Input Conversions/HHVs . The purpose of this lookup table was to create a method for automatically converting large quantitie s of fuel HHV. A list of all HHV conversion
factors can be found in Table B-7 of Appendix B . After all of the units for HHV were standardized, a series of update queries were programmed to make the HHV conversions. These queries converted the numeric HHV by multiplyi ng by the conversion factor assigned to each
base unit in the LOOKUP: Fuel Input Conversions/HHVs table.

As a final step, the standardized HHV for each common fuel type were averaged in order to establish an average (mean) HHV for each common fuel type reported in the 2008 questionnaire and 2009 Test Plan. Standardized HHV were averaged for all data points that represented data measured on an “as received” ba sis. The ranges of standardized HHV for each fuel type were investigated in or der to determine outliers. Any va lues that were inconsistent by a factor of 10 were compared to similar data from the same facility in order to determine if a29 typographical error had been made. Typographica l errors were corrected. For the remaining questionable values, the “Standardized Paramete r _Units” field for each was populated with a note describing the reported data as inconceivable. The questionable numeric values were still standardized, but none were us ed in any further analyses.

5.2 Standardization of Fuel Parameters

Many liquid fuel boiler and process heaters do not have any air pollution control devices installed to control emissions of mercury, HCl, or metallic HAP. In the absence of control devices, the Agency assumed that all of the merc ury and metallic HAP contained in the fuel was
emitted and all of the chlorine contained in th e liquid fuel was emitted as HCl. Although fuel analysis would only be considered for uncontrolled liquid units, da ta were standardized for all fuel types so other analyses such as fuel content variability could be done.

For each of the fuel analysis parameters discussed below, a numeric field called
“ParameterValueNumeric” was created in order to mirror the data reported in the text-based “Parameter_Value” field. This numeric field allo wed mathematical operators to be applied to the
data in order to calculate emission factors. If the parameter was reported as non-detect, the brackets and other symbols reported in non-detect records were removed from the data prior to populating the “ParameterValueNumeric” field. The “ParameterValueisNonDetect” field was updated to “ND” if the parameter was reported as a detection limit a nd “Numeric value not provided” if the parameter was reported as non- detect but no detection limit was reported for the parameter. In addition, a fiel d called “CorrectedParameter_Units” was created to hold all of the
units of measure after correc ting for typographical errors or notes contained in the “Parameter_Units” field.

5.2.1 Moisture Content The preferred format of sta ndard concentrations of mercur y, chlorine, and metallic HAP were milligram per gram on a dry basis. In order to calculate these concentrations, any analysis reported on an “as received” basis and reported moisture content had to be adjusted to a dry basis30 as shown in Equation 1, where “Fuel Parameter” is either the HHV, or mercury, chlorine, or
metallic HAP content of the fuel.

Equation 1 – Moisture Correction for Dry Basis



### (%) 1[ ] 100% Fuel Parameter Reported Moisture Content 



The moistures were all reported in units of percent and so no conversions were necessary
to standardize these moisture contents. Some of the moisture contents were reported as “<0.05,”
and in these cases the numeric value wa s used as the percent moisture in Equation 1 above. Some of the moisture contents were reported to be greater than 100 percent and these values were not used in any equations as they were unrea listic values for moisture content. If the data was reported on an as received basis but no moistu re content was reported, the moisture content was assumed to be zero for the purpose of standardizing to a dry basis.

5.2.2 Mercury, Chlorine and Metals Content The fuel analysis parameters for mercury, ch lorine, and metals were reported as either
concentrations or emission factors. The data reported as concentr ations were first standardized to units of milligram per gram on a dry basis, befo re they were converted into emission factors. A table was developed to assign each of the reported units to the appropriate conversion equation. Each equation was labeled with the prefix “FA” for fuel analysis followed by the appropriate equation ID. A list of th ese conversion equations is shown in Table B-8 of Appendix B . The “StdParemeterConc(mgperg dry)” field contains the result of multiplying the “ParameterValueNumeric” field by th e appropriate conversion equation.

Next, the reported emission factor data was standardized to lb/MMBtu and the
standardized concentration data was converted to standardized emission factors in units of lb/MMBtu. Mercury and metals concentration data were converted into mercury and metals
emission factors. Chlorine concentration data wa s converted into HCl emission factors. A list of the conversion equations used to standardize emission f actors to units of lb /MMBtu is shown in31 Table B-9 of Appendix B . The “StdParameter for EF” field c ontains the result of multiplying the “StdParemeterConc(mgperg dry)” fiel d (for concentration data) or the “ParameterValueNumeric” field (for emission factor data) by the appropriate conversion equation. When an HHV was necessary for thes e conversions, the HHV was adjusted to a dry
basis and used in the conversions.

A grouping of binary compounds composed of the elements sulfur and oxygen, includin g sulfur monoxide (SO), sulfur dioxide (SO 2 ), sulfur trioxide (SO 3 ), lower sulfur oxides (S n O, S 7 O 2 , S 6 O 2 ) and higher sulfur oxides (SO 3+x where 0<x ≤ 1). TEQ Toxicity Equivalent. Used to measure all toxic dioxins and furans in terms of the most toxic dioxin: 2,3,7,8-TCDD. Total (including condensibles) The total of all solid and liquid particulate matter, including gases or vapors that condense to form particulate matter.
Wet Used to describe the basis for emissions concentrations. Concentrations reported as “wet” are based on the actual moisture content of the stack gas. For comparison, concentrations measured as “dry” (e.g., dscf) are based on a mo isture content of zero percent. μ g Microgram. A unit of measurement for mass.

μ g/dscm Micrograms per dry standard cubic meter. A unit of measurement for pollutant emission concentration.40 APPENDIX B

1 For emission test data repo rted in the survey, if O 2 adjustment was not reported, it was estimated to be zero for all pollutants except for CO. For CO, a standardized value was not calculated unless the O2 level was reported during the emission test. For CEMS data, data was only conv erted when the CEMS measurements included an O2 correction. For all data reported in the phase II test data , the values were converted only when oxygen corrections were provided. Most of the phase II test data did not require these conversions since emission data was requested using a single unit of measure. 2 Assumed ppmw is ppm by weight at standard conditions; density of air assumed to be roughly equivalent to density of exhaust stream. 3 Assumed cubic feet of exhaust flow volume were reported at dry standard conditions when not otherwise specified. 4 Individual test files were reviewed and emissions were reported at 7% O 2 . 5 Assumed MMCF is million cubic feet at actual conditions. 6 Assumed 85% boiler efficiency. 7 Assumed 1000 lbs exhaust gas is dry exhaust; density of air at dry conditions is 0.075 lb/ft 3

. 8 Assumed one day is equivalent to 24 hours of operating time and nothing less. 9 Assumed one month is equivalent to 30 days of operating time and nothing less. 10 To convert PM, metals, and acid gas data reported in concentrations data from their standardized concentrations toan emission rate, and to convert CO, NOx, and other organic HAP data from emission rates to concentrations, FFactors were applied to relate exhaust volumes to fuel energy inputs during the tests. The 8 conversion equations with the prefix “FF” call an F-factor into the conversion equation to standard ize the data. F-Factors themselves are fuel-specific. A unique F-Factor was a ssigned to each emission test based on th e fuel reported during the test, and that value was used in the standardization of the reported data. A list of all F-Factors used in converting emission test and CEM data (and the sources from which the F-Factors were found) can be found in the LOOKUP: ET Fuel F-Factors database table. If an emission test reported combusting more than one type of fuel during the test, an average of the F-Factors for each fuel type in the mix were used. If an emission test reported a fuel for which no FFactor could be found, the data points corresponding to that fuel were not standardized in this step. Similarly, if an emission test reported a fuel combination and one or more of the constituent fuels had no F-Factor assigned, only the fuels with known F-Factors were av eraged to get the final value.51 Table B-2: Higher Heating Values
