### INTRODUCTION
This document describes how emissions data 

### in the Industrial Combustion Coordinated Rulemaking (ICCR)emissions test database were processed 

### by Eastern Research Group (ERG) to develop standard pollutant concentrations and emission factors. Emissions test databases were developed to serve as repositories 

### of emissions information for combustion sources 

### of interest to the ICCR effort. ERG developed databases of emissions data 

### for boilers, incinerators, indirect-fired process heaters, and landfill gas flares, and another EPA contractordeveloped databases 

### ofemissions data for turbines and reciprocating internal combustion engines. This memorandum discusses 

### the emissions test databases 

### (ETD)developed 

### by ERG 

### for the ICCR 

### effort and specifically addresses the unit conversions and calculations used 

### in the databases.
The ETD were developed and released 

### by EPA 

### as several individual databases with each database containing data 

### from different test reports and having a distinct version number. This approach allowed users of the database to access the data as they became available rather than wait until all data had been entered and processed. This memorandum covers the following versions 

### of the 

### ETD:

### 2.0 DEVELOPMENT 

### OF 

### STANDARD CONCENTRATIONS
One purpose of developingthe 

### ETD was to compare pollutant emissions levels measured at different facilities. The pollutant emissions data that were reported in the test reports and extracted and entered into the 

### ETD are expressed in many different units of measurement. 

### In order to make comparisons of pollutant emission levels measured at different facilities, it was necessary to convert the reported emissions data from all facilities to a standard unit of measurement.
Standard Concentration5


### In defining a standard unit of measurement, 

### EPA determined that 

### a standard unit was needed forpollutants that are emitted as gases (volatile, semi-volatile pollutants), a second standard unit was needed for pollutants that are emitted 

### as solids or particulate matter 

### (PM), and a third standard unit was needed for pollutants that exhibit radioactivity (radionuclides). Generally, emissions of volatile pollutanrs are reponed on a relative basis, such as volume of pollutant per volume of stack gas, and emissions 

### of pollutants emitted 

### as 

### PM are reported on an absolute basis, such as mass 

### of pollutant per volume 

### of stack 

### gas. Radionuclide emissions are reported on 

### an absolutebasis in units of amount of radioactivity released per unit of time. Semi-volatilepollutant emissions may be reported 

### on either a relative or absolute basis. Therefore,

### EPA defined the standard concentration unit for volatile and semi-volatile pollutants to be unit volume 

### of pollutant per billion units 

### of volume of stack gas at an oxygen concentration of three percent, or part 

### of pollutant per billion parts of stack gas at an oxygen concentration of three percent (ppb @ 3960,). The standard 

### unit defined for pollutants emitted 

### as 

### P31 was micrograms 

### of pollutant per dry standard cubic meter of stack gas at an oxygen concentration of three percent @g/dscrn @ 3%0,). The standard unit developed for radionuclides was microcuries per dry standard cubic meter 

### of stack gas at an oxygen concentration 

### of three percent &Ci/dscm 0 3% 0,). A curie (Ci) is a unit of radioactivity and is defined as 3.70 X 10" disintegrationsper second.

3Conversion 

### Ea -uation~ Equations were developed to convert the emissions 

### data from the units 

### as extracted and entered into standard units. An equation 

### was developed for each combination of pollutant type (volatile/semi-volatile, 

### PM, radionuclide), reported emissions units, and, where applicable, sample volume units. Table 

### B. 1

### in Appendix 

### B lists each combination of pollutant type, emissions units, and, where applicable, sample volume units found 

### in 

### ETD Versions 3Q4.1, and 4.2. 

### Also, for each combination,the table identifies in which version(s) it was included. Table 

### B.2 presents the mathematical terms and operations used 

### in each equation by equation number. Each equation was translated into 

### a computer code and the codes for all equations were combined to form a computer program. The emissions data, as entered, were converted to standard units by applying the computer program to the data. After the data were converted, the results were rounded 

### off to three significant digits. The computer code developed 

### for each equation 

### is provided in Table 

### B.3by equation number. The database fields containing data used 

### in conversions and the fields containing the results 

### of conversions are described in Appendix 

### C.
Revisions To Conversion Equations
Two mathematical constants used 

### in some of the conversion equations were revised after Versions 3.0,4.1, and 4.2 

### of the 

### ETD were developed and during development of later versions released after the ICCR process ended. The constant used to represent absolute zero temperature on the Rankine scale 

### was revised from 

### -460 to -459.67 and the constant used 

### as the percent 

### of oxygen 

### in ambient air 

### was revised from 20.9 to 20.946. The constants used in Version 3.0,4.1, and 4.2 are not incorrect; they were revised to increase the accuracy 

### of the results produced by the conversion equations.


### Corrections To 

### Conversion Eauations
After Versions 3.0,4.1 and 4.2 of the 

### ETD were developed, errors were found in some 

### of the conversion equations. The equations with errors are identified in Table B.3. The errors are described below. 4The constant used to convert cubic feet to cubic meters, and vice 

### versa, 

### was found to be incorrectly rounded. 

### A value 

### of 

### 35.3 14 ft 3/m3 

### was used instead 

### of 

### the correct value 

### of 

### 35.3 15. It should be noted that, in most cases, the error

### has an insignificant effect 

### on the 

### final result. The English and metric values used 

### as the volume 

### of one mole 

### of 

### gas at standard temperature and pressure were incorrect. Metric values used were 0.0224 

### or 0.02404 dscdgmole instead 

### of the correct value 

### of 0.024056 dscdgmole. The English value used was 385.55 dscf/lb mole instead 

### of the correct value of 385.34 dscf/lb mole. One equation 

### (EQ.05 1)was incorrect because it 

### was not adjusted for the oxygen content 

### (07%) 

# - of the stack gas. 

### Four equations (EQ.059, EQ.088,EQ.090, EQ.094) were incorrect because they included an adjustment to standard temperature when no adjustmentfor temperature should be included. These equations convert emissions data entered on a relative volume basis to ppb @ 

### 3% 07, which is also 

### on a relative volume basis. Emissions data expressed on a relatrve volume basis do not change with temperature and, therefore, the data should not be adjusted for temperature.

0 The computer code for one equation (EQ.020)was revised after release 

### of Version 3.0 because 

### of what appeared to be a typographical error. A constant used 

### in the code with a value of 62500000000 was changed to the correct value of 64200000000 

### in Versions 4.1 and 4.2. All 

### of these errors in the equations were corrected after the release of Version 

### 4.2except 

### for the error in Equation 5 1 and the correction to Equation 20. which were corrected between releases 

### of Version 3.0 and 4.1.
Run 

### Emissions Data Based On Detection Limits


### In database Version 

### 3.0, when the reported emissions data for one 

### or more runs 

### was based on the method detection limit (non-detect runs), the largest of the values reported for the non-detect runs was used to calculate the emissions in standard concentrations units for all non-detect 

### runs. 

### For example, suppose Run 1 was non-detect and the reported emissions value of 1.0gr/dscf was based on the method detection limit. 

### Run2 was also non-detect and the reported value of 2.0 gr/dscf was based 

### on the detection limit. Results for Run 3 were 4.0 gr/dscf and were based 

### on a detected value. The largest non-detect value (2.0 gr/dscf) would be used to

twWU59NS02WEMOSU3AT.ACALC. 5 WPD'calculatethe emissionsin standard concentrationunits for both Run 

### 1 and Run 

### 2. The value reported for Run 

### 3 (4.0gr/dscf) would be used 

### to calculate the emissions 

### in standard units for Run 

### 3.
Non-detect 

### runs in Versions 4.1,4.2 and subsequent versions were treated differently. The value reported 

### for each non-detect 

### run was used to calculate the emissions in standard units 

### for that 

### run.
3.0 

### DEVELOPkIENTOF EMISSION FACTORS
Similar

### to defining the standard units of measurement for emissions data, 

### a standard unit of measurement for emission factors was defined 

### as pounds of pollutant emitted per million British thermal units of heat input from the fuel (IbMIvlBtu). Basing the emission factors on heat input 

### (IvMBtu) rather than the amount of fuel used (tonshr,gallons/hr, poundshr, etc.) allows for 

### a comparison between factors from different facilities and between factors from different fuel types. The following approach was used to develop the emission factors: Step 1: Develop conversion factors for each test included in the Equipment Table. Conversion factors are in units of dry standard cubic feet of stack gas at zero percent oxygen per million 

### Btu of heat input (dscf/MMBtu @ 0960,). 

### - Step 3:Develop emission factor equations that 

### (a) convert the pollutant emissions data in standard units (pddscm @ 

### 3%07,ppb @ 3%07)to Ib/dscf @ 3%0,, and (b) multiply the converted emissions data by ;he conversion Factors (from Step 1) to obtain emission factors in lb/MMBtu. 

### In Step 1, a conversion factor was developed 

### for and added to each record (row of data) in the Equipment table. A hierarchal approach based on available data was used to develop the conversion factors. The hierarchy is shown below in order of most preferred to least preferred:

0 An F-factor based on an analysis of the fuel being burned during the test and provided in the test report was used 

### as the conversion factor. (See Appendix A: Glossary for 

### a description of F-factors.)

6e An average of F-factors reported for other tests at the same facility burning 

### the same 

### me of fuel 

### was used 

### as the conversion factor.

0 The fuel flow rate reported in 

### MMBtu/hr, the reported stack 

### gas flow rate in dscfm, and the reported oxygen content of the stack 

### gas in percent were used to calculate the conversion factor.

0 The average heat input reported in 

### MMBtu/hr, the reported stack gas flow rate in dscfm, and the reported oxygen content of the stack 

### gas in percent were 

### used 

### to calculate the conversion factor.

e The reported fuel 

### flow rate in units of mass or volume per unit of time, the reported heating value 

### of the fuel in 

### Btu per unit of mass or volume, the reported stack gas flow rate in dscfm, and the reported oxygen content of the stack 

### gas in percent were used to calculate the conversion factor.

0 An F-factor provided in Method 19 specific to the fuel being burned during the test was used 

### as the conversion factor’.

0 An average of conversion factors calculated for tests at other facilities burning the same type of fuel was used as the conversion factor.

0 An F-factor provided in Method 

### 19 for a fuel similar to that burned during the test was used as the conversion factor‘. Example: The F-factor provided in Method 19 

### for natural gas was used as 

### a conversion factor for the fuel ‘bprocess gas.”

0 An average of two or more F-factors provided in Method 19 for fuels similar to those burned during the test was used as conversion factor. Example: The F-factors provided 

### in Method 19 for wood and for municipal solid waste were averaged to develop the conversion factor 

### for the fuel “wood/solid waste.”

0 An average of conversion factors developed from other facilities burning a similar fuel and an F-factor provided in Method 19for 

### a similar fuel were averaged to develop the conversion factor. Example: The average 

### of conversion factors developed for facilities burning medical waste and the Method 19 F-factor for municipal waste were averaged to develop a conversion factor for the fuel type “medical waste/so1id waste.” After conversion factors 

### for each record 

### in the ETD were developed, the emission factor equations were developed in Step 2. One equation was developed to convert emissionsdata in pugldscm @ 

### 3% 0, to lb/dscf and multiply by the conversion factor and a second equation was developed to convert ppb @ 3% 0, to Ib/dscf and multiply by the conversion factor. Theemission factor equations are included in Table 

### B.2 and are numbered EQ.044 and EQ.045. The emission factor equations were translated to computer code and the code was applied 

### to the emissions data to calculate the emission factors. The computer codes for EQ.044 and EQ.045 are provided 

### in Table 

### B.3.

### QUALITY ASSURANCE (QA) 

### OFEMISSIONS DATA CONVERSIONS AM) 

### CALCULATIONS Quality assurance was performed on the conversion equations and emission factor equations after they were developed, on the computer code after the equations were transcribed to code, and on the results of conversions and calculations after the computer code was applied to the data. Each QA step 

### is described 

### in the following paragraphs.
OA of Equation Development
The approach or method used by each conversion equation and emission factor equation was checked to confirm that it produced the desired results. 

### For example, the equation that converts emissions 

### in gr/dscf to ,ug/dscm @ 3% 0, was checked to confirm that the result 

### is in pg/dscm @ 3% 0, and not in Ib/dscm 0 3% O,, which could happen if the conversion from pounds to micrograms was omitted.
The conversion equations and emission factor equations were QA'd to confirm that correct values for constants were used and that they were used consistently. 

### For example, each equation that involves converting cubic feet to cubic meters, 

### or vice versa, was checked to verify that 

### a value of 35.3 

### 15 cubic feetkubic meters was used and not another number. 

### Also, each applicable equation 

### was checked to confirm that the same number 

### of significant figures were used in conversion factors throughout all equations. For example, 35.3 15 cubic feetkubic meters was checked to confirm it was used consistently and not 35.32 or 35.
Each conversion equation was checked to determine if it should include an adjustment to standard temperature. A temperature adjustment is necessary when 

### an equation convertsemissions on 

### a volume-per-volume basis to 

### a mass-per-volume basis 

### (e.g., ppb topg/dscm), or vice versa, or when an equation converts mass-per-volume to mass-per-volume (e.g., Ib/dscf to pg/dscm). However,when 

### an equation converts emissions on 

### a volume-per-volume basis to 

### a volume-per-volume basis (e.g., pprn to ppb), the equation should not include 

### an adjustment for temperature. Unless the standard temperature for emissions measurements was the same as 

### EPA’s standard temperature 

### (68 degrees Fahrenheit), the result produced by such 

### an equation would be incorrect.
Each conversion equation 

### was checked to confirm that the adjustment to three percent oxygen was calculated correctly. For example, the equation that converts ppm to ppb @ 

### 3%

### 0, uses the 

### 0, percent measured in the stack gas in the calculation: ((20.946 

### - 3)/(20.946 

## - RunO2)). However, the equation that converts ppm @ 8% 

### 0, 

### - to ppb @ 3% 0, uses 8% in the adjustment rather than the stack 0,: ((20.946

### - 3)/(20.946 

### - 8)).
OA of Computer Code
After each equation was transcribed to computer code, the code was QA’d to confirm that the transcription was performed correctly. This involved confirmingthat parentheses and mathematical operators (symbols for addition, subtraction, multiplication, division) were positioned correctly to produce the desired result.
Numerical values were also checked to see that they were transcribed correctly. For example,Equation 

### 003 contains the mathematical operations “1/7000 

## * 453.59* 1000000*35.3 14”, while the computer code for Equation 

### 003 contains “2290000”,which is the result produced by the mathematical operations 

### (2288362)rounded off to three significant digits.
OA 

### of Results of Conversions and Calculations
After the conversions and calculations were performet, on the emissions data by the computercode, the results were QA’d. For each equation used in the database, at least one 9 twU<.\859NS\O?UIE,LIOSU)XTXCALC.WPDrecord in the emissionsunits applicable to the equation

### was selected and the calculations performedby the equationwere repeated manuallyusing the emissionsdata. The results produced by the manual calculations were compared 

### to the results produced by the computer code (program).

### OF DATABASE

### FIELDS
The same database formatused for data entry was 

### also used for data processing. After data were entered and quality control and quality assurance (QCIQA) checks were performed, the Test DataTable 

### was renamed CorrectedTest Data Table. Fields were added 

### to the Equipment Table and CorrectedTest DataTable to contain data used 

### in conversions and calculations and 

### to present the results. The fields that were added are described beIow. All other database fields are described in detail 

### in the memorandum 

### “ExrractionofData From Emissions 

### TestReporrs Used 

### to Develop the 

### ICCR Emissions 

### TestDatabase.”2
EauiDment Table
Conversion Factor
A numeric value developed from test data and used to calculate an emission factor. Conversion Factors are described 

### in detail 

### in Section 3.1 of this memorandum.
Conversion Factor Basis
A description of the method used to develop the Conversion Factor. The different methods used to develop Conversion Factors are described in detail in Section 3.1 of this memorandum.
Source
Indicates the source, or project, that provided the emissions test data:
AFbIA- Indicates the data were obtained from a test report provided by the American Furniture Manufacturers’ Association. AT 

### Hot Spots- Report was obtained from the California Air Resources Board (CAB)and presents results from one of CARB’s “hot spots” tests.

### AP42-Data were obtained 

### from a 

### test 

### report used to 

### developAP-42 emission 

### factors. ICWI/OSWI- Report 

### was obtained 

### from

### EPA's Industrial 

### and Commercial Waste IncineratodOther Solid Waste Incinerators 

### (IWOSwr)

### project files. 

### STIRS- Data were obtained 

### froma stack 

### test report included in 

### the 

### STIRS database. Survey- 

### Test report was provided 

### by a facilityincluded in 

### an EPA Section 114 Information Collection Request. 

### UTZL- The report came from the docket developed for PA'Sutility boiler study. The study was performed to qualifyand quantifyhazardous air pollutants (HAPS) emitted from these boilers in order to determine if emission levels warrant regulations to reduce emissions. 

### Data Date
The date that the version of the 

### ETD 

### was compiled.



### RunData Table- No fields were added during conversions and calculations.


### Corrected Test Data Table
CAS Chemical Abstracts Service. Refers to a unique, identifyingnumber assigned by the CAS Division 

### of the American Chemical Society to each distinct chemical substance recorded 

### in the CAS Chemical Registry System. The CAS number 

### was used in addition to the pollutant name to identify specific pollutants. Two different pollutants may have names that are very similar in spelling (appearance). Also, some individualpollutants have synonyms.

The molecular weight 

### of the pollutant. This value 

### is used 

### in some of the equations that convert the emissions data 

### as entered to standard units.

### HAP Hazardous Air Pollutant. This 

### was added to the table to identify pollutants that are HAPS.

Used to identify the pollutant 

### as a metal 

### or nonmetal when converting the emissions data 

### as entered to a standard concentration. 

### RunlND; Run2ND; Run3ND This field is used to identify non-detect runs. A computer program is used to identify non-detect runs entered with 

### a “4’ 

### in front of the value and place an 

### “ND”in this field. During calculations, the “d’ is removed from the value and the value entered 

### as text 

### is converted to a number. Also, see the description provided below for the 

### “DL” field. 

### NewEXH1; NewEXH2; NewEXH3 The stack gas volumetric tlow rate as measured. dscfm. adjusted to standard temperature (68 degrees 

### F) and zero percent oxygen. This field was used only in V3.0 to convert emissions data entered as ”lb/hr” to standard units. 

### In later versions, the adjustment was included 

### in the equation that converts lbh to the standard units. 

### NewRunConcRl; NewRunConcK: NewRunconcR3 The standard concentration calculated (“corrected”) for each test 

### run. For non-detect runs in V1.0, V2.0, and V3.0, the value in the 

### “DL” field is used to calculate the standard concentration for all non-detect runs. 

### For non-detect runs in V4.1, V4.2, and V4.3, the value entered for the detection limit for each 

### run is used to calculate the standard concentration for that run. See Section 2.0 of this memorandum for a detailed description 

### ofhow standard concentrations were calculated. 

### NewConcUnits The units of measurement for the standard concentrations. Data for type “metal” pollutants are converted to standard concentrations in units 

### of pg/dscm @3%

### 0,. Data for “Nonhletal” pollutants are converted to standard units of ppb @3%07.Data for radionuclides, measured in Curies (Ci), are converted to pg/Ci @3%0,. 

### Run1 EF (IbfiIlbIBtu);

### Run2 

### EF (IbfiIMBtu);Run3 

### EF (Ib&IMBtu) The emission factor calculated for each run. See Section 3.0 of this memorandum for a detailed description of how emission factors were calculated.
