Based on Engine Specification obtained provided by Mr. Aaron Wade (Anadarko) to Mr. Raghu Soule (Trinity) 

via email on August 8, 2012. Per provided information, this engine is EPA Tier II certified (Table 1 of Federal 

Register/Vol. 63, No. 205, October 23, 1998 and 40 CFR 89.112(a)). 

Based on footnote b of AP-42 Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and Diesel 

Industrial Engines (October 1996). Per footnote b of Table 3.3-1, all PM is assumed to be < 1 um, therefore, 

assumed PM2.5 = PM10 = PM. 

Emission factors are based on AP-42, Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and 

Diesel Industrial Engines (October 1996). Emission factors for diesel fuel are used.

Lead emission factor was obtained from EPA guidance document: Locating and Estimating Air Emissions from 

Sources of Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor for 

distillate oil-fired gas turbines was used as a surrogate for distillate oil-fired engines due to lack of emission 

factors. An average brake-specific fuel consumption (BSFC) of 7,000 Btu/hp-hr was used to convert from 

lb/MMBtu to lb/hp-hr.

All TOC is assumed to be VOC. TOC emission factor has been calculated as the sum of exhaust and crankcase 

emission factors.

Anadarko is proposing the use of Ultra Low Sulfur Diesel (ULSD) for all diesel combustion sources. Therefore, 

emissions have been calculated based on a maximum sulfur content of 15 ppm in diesel fuel assuming that 98 

percent of sulfur in the fuel is oxidized to SO2 and 2 percent of sulfur in the fuel is oxidized to H2SO4 based on 

Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 

2003.

Lead emission factor (2.9x10-5 lb/MMBtu) is obtained from EPA guidance document: Locating and Estimating Air 

Emissions from Sources of Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor 

for distillate oil-fired gas turbines is used as a surrogate for distillate oil-fired engines due to lack of specific emission 

factors for distillate oil-fired engines.

Factor is based on AP-42, Table 3.3-1. All TOC is assumed to be VOC. TOC emission factor is calculated as the sum of 

exhaust and crankcase emission factors.

Rating is based on the engine Specification Sheets. All engines with rating around 300 HP are considered to have 300 

HP for consistency. A total of nine 3rd Party engines fall into this category.

Operating time for this engine is conservatively assumed to be 24 hrs/day.

Per 40 CFR 80.510(b), Anadarko proposes the use of Ultra Low Sulfur Diesel (ULSD) for all diesel combustion 

sources. Therefore, emissions have been calculated based on a maximum sulfur content of 15 ppmw in diesel fuel 

assuming that 98 wt.% of sulfur in the fuel is oxidized to SO2 and 2 wt.% of sulfur in the fuel is oxidized to H2SO4 based 

on AP-42 Appendix A, table 3.4.1 footnote e and Draft Regulatory Impact Analysis: Control of Emissions from Nonroad 

Diesel Engines, EPA420-R-03-008, April 2003. 

Based on footnote b of AP-42 Chapter 3, Table 3.3-1, all PM is assumed to be < 1 μm, therefore, assumed PM2.5 = PM10 

= PM. 

According to Specification Sheet, this engine is EPA Tier 2 certified. The NOx+NMHC emission factor is 6.6 g/kW-hr. 

Factor for NOx+NMHC can also be found in 40 CFR, Part 89.112 Table 1. From the same reference, CO emission 

factor is 3.5 g/kW-hr, and PM emission factor is 0.2 g/kW-hr.

II (Table 1 of Federal Register/Vol. 63, No. 205, October 23, 1998 and 40 CFR 89.112(a)). 

Lead emission factor was obtained from EPA guidance document: Locating and Estimating Air Emissions from Sources of 

Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor for distillate oil-fired gas 

turbines was used as a surrogate for distillate oil-fired engines due to lack of emission factors. An average brake-specific 

fuel consumption (BSFC) of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr.

Per footnote f of AP-42 Chapter 3, Table 3.4-1, non methane VOC emission factor has been taken as 91% of TOC emission 

factor. 

Rating is based on the engine Specification Sheets. All engines with rating around 860 HP are considered to have 860 HP for 

consistency. A total of two 3rd Party engines fall into this category.

Assumptions: Max operating time of 24 hr/day. Information provided by Mr. Aaron Wade (Anadarko) on August 8, 2012.

Anadarko is proposing the use of Ultra Low Sulfur Diesel (ULSD) for all diesel combustion sources. Therefore, emissions 

have been calculated based on a maximum sulfur content of 15 ppm in diesel fuel assuming that 98 percent of sulfur in the 

fuel is oxidized to SO2 and 2 percent of sulfur in the fuel is oxidized to H2SO4 based on Draft Regulatory Impact Analysis:

Emission factors are based on AP-42 Chapter 3, Table 3.4-1, Emission Factors for Large Stationary Diesel and all Stationary 

Dual-fuel Engines (October 1996).

PM10 and PM2.5 emission factors obatined by applying the ratio of PM/PM10 and PM/PM2.5 from AP-42 Chapter 3, Table 3.4-

Anadarko is proposing the use of Ultra Low Sulfur Diesel for all diesel combustion sources. Therefore, emissions have 

been calculated based on a maximum sulfur content of 15 ppm in diesel fuel assuming that 98 percent of sulfur in the 

fuel is oxidized to SO2 and 2 percent of sulfur in the fuel is oxidized to H2SO4 based on Draft Regulatory Impact 

Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003. 

Operating time per engine has been conservatively assumed to be 24 hrs/day. 

Per footnote f of AP-42 Chapter 3, Table 3.4-1, non methane VOC emission factor has been taken as 91% of TOC 

emission factor. 

Based on the Engine Emission Report sent by Ms. Kathryn Maness (Anadarko) to Mr. Raghu Soule (Trinity) via email 

on July 3, 2012. The NOX emission comply with IMO Tier II limit and NSPS, Subpart IIII (40 CFR 60.4204(c)(2)(ii)).

 Pollutant Emission Factor 

Basis

Emission factors are based on AP-42, Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and Diesel 

Industrial Engines (October 1996). Emission factors for diesel fuel are used.

Lead emission factor obtained from EPA guidance document: Locating and Estimating Air Emissions from Sources of 

Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor for distillate oil-fired gas 

turbines was used as a surrogate for distillate oil-fired engines due to lack of emission factors. An average brake-specific 

fuel consumption (BSFC) of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr.

Information provided by Ms. Sara Carlson (Anadarko) to Mr. Rahul Pendse (Trinity) via email on March 11, 2013.

Engine specifications provided in a needs list spreadsheet by Ms. Kathryn Maness (Anadarko) to Mr. Raghu Soule 

(Trinity) via email on July 2, 2012.

Anadarko is proposing the use of Ultra Low Sulfur Diesel for all diesel combustion sources. Therefore, emissions have 

been calculated based on a maximum sulfur content of 15 ppm in diesel fuel assuming that 98 percent of sulfur in the fuel 

is oxidized to SO2 and 2 percent of sulfur in the fuel is oxidized to H2SO4 based on Draft Regulatory Impact Analysis: 

Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003. 

Operating time per engine has been assumed to be 1 hr/day and 100 hrs/year.

All TOC is assumed to be VOC. TOC emission factor has been calculated as the sum of exhaust and crankcase emission 

factors.

Based on footnote b of AP-42 Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and Diesel Industrial 

Engines (October 1996). Per footnote b of Table 3.3-1, all PM is assumed to be < 1 um, therefore, assumed PM2.5 = 

PM10 = PM.

 Pollutant Emission Factor 

Basis Emission Factor 

Lead emission factor obtained from EPA guidance document: Locating and Estimating Air Emissions from Sources 

of Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor for distillate oil-fired 

gas turbines was used as a surrogate for distillate oil-fired engines due to lack of emission factors. An average brakespecific fuel consumption (BSFC) of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr.

Per footnote f of AP-42 Chapter 3, Table 3.4-1, non methane VOC emission factor has been taken as 91% of TOC 

emission factor. 

Engine specifications provided in a needs list spreadsheet by Ms. Sara Carlson (Anadarko) to Mr. Rahul Pendse 

(Trinity) via email on May 1, 2013.

Operating time for each engine has been conservatively assumed to be 24 hrs/day. 

Anadarko is proposing the use of Ultra Low Sulfur Diesel for all diesel combustion sources. Therefore, emissions 

have been calculated based on a maximum sulfur content of 15 ppm in diesel fuel assuming that 98 percent of sulfur 

in the fuel is oxidized to SO2 and 2 percent of sulfur in the fuel is oxidized to H2SO4 based on Draft Regulatory 

Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003. 

Emission factors are based on AP-42 Chapter 3, Table 3.4-1, Emission Factors for Large Stationary Diesel and all 

Stationary Dual-fuel Engines (October 1996).

PM10 and PM2.5 emission factors based on AP-42 Chapter 3, Table 3.4-2, Particulate and Particle-sizing Emission 

Factors for Large Uncontrolled Stationary Diesel Engines (October 1996). An average brake-specific fuel 

consumption (BSFC) of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr. PM < 3um taken as 

PM2.5. Total particulate emissions is the sum of filterable and condensable particulate emissions.

Based on footnote b of AP-42 Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and Diesel Industrial 

Engines (October 1996). Per footnote b of Table 3.3-1, all PM is assumed to be < 1 um, therefore, assumed PM2.5 = 

PM10 = PM. 

Emission factors are based on AP-42, Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and Diesel 

Industrial Engines (October 1996). Emission factors for diesel fuel are used.

Lead emission factor was obtained from EPA guidance document: Locating and Estimating Air Emissions from Sources 

of Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor for distillate oil-fired gas 

turbines was used as a surrogate for distillate oil-fired engines due to lack of emission factors. An average brakespecific fuel consumption (BSFC) of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr.

All TOC is assumed to be VOC. TOC emission factor has been calculated as the sum of exhaust and crankcase 

emission factors.

Anadarko is proposing the use of Ultra Low Sulfur Diesel (ULSD) for all diesel combustion sources. Therefore, 

emissions have been calculated based on a maximum sulfur content of 15 ppm in diesel fuel assuming that 98 percent of 

sulfur in the fuel is oxidized to SO2 and 2 percent of sulfur in the fuel is oxidized to H2SO4 based on Draft Regulatory 

Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003.

Types of Fuel. The emission factor for petroleum (All types in table C-1) was used to calculate emissions.

An average BSFC of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr to calculate emissions.

CH4, CO2 and N2O are included in the emissions of CO2 equivalent (CO2e), weighted according to their global 

warming potential (GWP). The GWP was obtained from 40 CFR 98, Subpart A, Table A-1 Global Warming 

Potentials (100-year Time Horizon).

Anadarko is proposing the use of Ultra Low Sulfur Diesel (ULSD) for all diesel combustion sources.

Note:

[1] For all diesel tanks on the drillship, the annual "capped" emissions of all the diesel tanks grouped together are calculated based on a throughput of 123 cubic meter/day * 2 * 200 days/yr * 264.17 * 1.16 = 15,076,710 gal/yr (approximately with 16% safety factor)

[4] For all three jet fuel tanks, throughput is 450 GPD based on the email from Ms. Sara Carlson (Anadarko) to Rahul Pendse (Trinity) on December 20, 2012. 

[5] Red/Primer was selected as the most appropriate shell color in Tanks 4.09d program, as yellow is not an option in TANKS 4.09d program.

[6] Based on EPA-approved TANKS 4.09d program. 6604500

[7] The largest tanks DR-FT-05 and DR-FT-06 on the drillship are chosen to calculate the drillship tanks annual emissions. 6604500

[8] Tank volume 21,000 gal is provided by Ms. Sara Carlson (Anadarko) to Mr. Rahul Pendse (Trinity) via email on March 8, 2013.

[2] Total Standing Losses = (maximum hourly standing losses for biggest tank on the supply boat) * (24 hrs/day) * 200 days/yr. Only the standing losses are calculated since diesel from all tanks on the supply boat will only be unloaded into the drillship tanks and no 

filling of tanks occurs on the supply boat.

[3] Total Standing Losses = (maximum hourly standing losses for biggest tank on the anchor handling boat) * (24 hrs/day) * 200 days/yr. Only the standing losses are calculated since diesel from all tanks on the anchor handling boat will only be unloaded into the drillship 

tanks and no filling of tanks occurs on the anchor handling boat.

Well Completion Total Emissions from Tanks

Standing Loss Total Emissions

The average diesel fuel usage for the drillship is 774 bbl/day. For conservative assumption, a throughput equal to twice the average fuel usage restriction of 774 bbl/day is used and it is assumed that all fuel is 

loaded into the largest tank DR-FT-05 to calculate the maximum total tank VOC emissions (tpy) on the drillship.

Note: Potential to Emit is limited by proposed supply boat wide fuel consumption limit of 200 bbl/day. Refer to fuel based 

consumption factor sheet for details.

VOC emission factor is based on AP-42 Chapter 3, Table 3.4-1, Emission Factors for Large Stationary Diesel and all Stationary 

Dual-fuel Engines (October 1996).

Lead emission factor (2.9x10-5 lb/MMBtu) is obtained from EPA guidance document: Locating and Estimating Air Emissions 

from Sources of Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor for distillate oilfired gas turbines was used as a surrogate for distillate oil-fired engines due to lack of emission factors. An average brakespecific fuel consumption (Brake Specific Fuel Consumption (BFSC)) of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to 

lb/hp-hr.

Per footnote f of AP-42 Chapter 3, Table 3.4-1, non methane VOC emission factor is 91% of TOC emission factor. 

Engine rating is based on EPA Region 4 Permit No. OCS-EPA-R4005-M1. 

Operating time for this engine is conservatively assumed to be 24 hrs/day.

Per 40 CFR 80.510(b), Anadarko proposes the use of Ultra Low Sulfur Diesel (ULSD) for all diesel combustion sources. 

Therefore, emissions have been calculated based on a maximum sulfur content of 15 ppmw in diesel fuel assuming that 98 wt.% 

of sulfur in the fuel is oxidized to SO2 and 2 wt.% of sulfur in the fuel is oxidized to H2SO4 based on Draft Regulatory Impact 

Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003. 

Per Caterpillar Marine Engine Guidance, for Caterpillar 3516C, displacement of each cylinder is 78.08 L/16 cylinders =4.88 

L/cylinder which is less than 5L/cylinder. Therefore, according to 40 CFR 94.8(a)(2)(i), the emission factors of NOx, CO and 

PM are 7.2, 5 and 0.2 g/kW-hr respectively. 

Emission factor of PM2.5 and PM10 are calculated based on ratio of PM/PM2.5 and PM/PM10 which are obtained from AP-42 

Chapter 3, Table 3.4-2.

Emission Factor 

Per footnote f of AP-42 Chapter 3, Table 3.4-1, non methane VOC emission factor is 91% of TOC emission factor. 

Engine rating is based on EPA Region 4 Permit No. OCS-EPA-R4005-M1. 

Operating time for this engine is conservatively assumed to be 24 hrs/day. 

Per 40 CFR 80.510(b), Anadarko proposes the use of Ultra Low Sulfur Diesel (ULSD) for all diesel combustion 

sources. Therefore, emissions have been calculated based on a maximum sulfur content of 15 ppmw in diesel fuel 

assuming that 98 wt.% of sulfur in the fuel is oxidized to SO2 and 2 wt.% of sulfur in the fuel is oxidized to H2SO4 

based on Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, 

Per Caterpillar C32 DITA Specifications, displacement of each cylinder is 2.5-5 L/cylinder which is less than or equal 

to 5L/cylinder. Therefore, according to 40 CFR 94.8(a)(2)(i), the emission factors of NOx, CO and PM are 7.2, 5 and 

0.2 g/kW-hr respectively.

Emission factor of PM2.5 and PM10 are calculated based on ratio of PM/PM2.5 and PM/PM10 which are obtained from 

AP-42 Chapter 3, Table 3.4-2.

VOC emission factor is based on AP-42 Chapter 3, Table 3.4-1, Emission Factors for Large Stationary Diesel and all 

Stationary Dual-fuel Engines (October 1996).

Lead emission factor (2.9x10-5 lb/MMBtu) is obtained from EPA guidance document: Locating and Estimating Air 

Emissions from Sources of Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor 

for distillate oil-fired gas turbines was used as a surrogate for distillate oil-fired engines due to lack of emission factors.

An average brake-specific fuel consumption (Brake Specific Fuel Consumption (BFSC)) of 7,000 Btu/hp-hr was used 

to convert from lb/MMBtu to lb/hp-hr.

Representative engine crane to be used for Well Evaluation activities. Information provided by Ms. Sara Carlson 

(Anadarko) to Mr. Rahul Pendse (Trinity) via email on April 18, 2013.

Assumptions: Max operating time of 24 hr/day at 100% Operating Load.

Anadarko is proposing the use of Ultra Low Sulfur Diesel (ULSD) for all diesel combustion sources. Therefore, 

emissions have been calculated based on a maximum sulfur content of 15 ppm in diesel fuel assuming that 98 

percent of sulfur in the fuel is oxidized to SO2 and 2 percent of sulfur in the fuel is oxidized to H2SO4 based on 

Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 

2003. 

Based on footnote b of AP-42 Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and Diesel 

Industrial Engines (October 1996). Per footnote b of Table 3.3-1, all PM is assumed to be < 1 um, therefore, 

assumed PM2.5 = PM10 = PM. 

Emission factors are based on AP-42, Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and 

Diesel Industrial Engines (October 1996). Emission factors for diesel fuel are used.

Lead emission factor was obtained from EPA guidance document: Locating and Estimating Air Emissions from 

Sources of Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor for distillate 

oil-fired gas turbines was used as a surrogate for distillate oil-fired engines due to lack of emission factors. An 

average brake-specific fuel consumption (BSFC) of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hphr.

Lead emission factor obtained from EPA guidance document: Locating and Estimating Air Emissions from 

Sources of Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor for 

distillate oil-fired gas turbines was used as a surrogate for distillate oil-fired engines due to lack of emission 

factors. An average brake-specific fuel consumption (Brake Specific Fuel Consumption (BFSC)) of 7,000 

Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr.

Per footnote f of AP-42 Chapter 3, Table 3.4-1, non methane VOC emission factor has been taken as 91% of 

TOC emission factor. 

Based on the engine specification sheet provided in Appendix G-3.

Operating time for this engine has been assumed to be 24 hrs/day. 

Anadarko is proposing the use of Ultra Low Sulfur Diesel for all diesel combustion sources. Therefore, 

emissions have been calculated based on a maximum sulfur content of 15 ppm in diesel fuel assuming that 98 

percent of sulfur in the fuel is oxidized to SO2 and 2 percent of sulfur in the fuel is oxidized to H2SO4 based on 

Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, 

April 2003. 

PM10 and PM2.5 emission factors based on AP-42 Chapter 3, Table 3.4-2, Particulate and Particle-sizing 

Emission Factors for Large Uncontrolled Stationary Diesel Engines (October 1996). An average brakespecific fuel consumption (Brake Specific Fuel Consumption (BFSC)) of 7,000 Btu/hp-hr was used to convert 

from lb/MMBtu to lb/hp-hr. PM < 3um taken as PM2.5. Total particulate emissions is the sum of filterable 

and condensable particulate emissions.

Emission factors are based on AP-42 Chapter 3, Table 3.4-1, Emission Factors for Large Stationary Diesel and 

all Stationary Dual-fuel Engines (October 1996).

Lead emission factor obtained from EPA guidance document: Locating and Estimating Air Emissions from Sources 

of Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor for distillate oil-fired 

gas turbines was used as a surrogate for distillate oil-fired engines due to lack of emission factors. An average brakespecific fuel consumption (Brake Specific Fuel Consumption (BFSC)) of 7,000 Btu/hp-hr was used to convert from 

lb/MMBtu to lb/hp-hr.

All TOC is assumed to be VOC. TOC emission factor has been calculated as the sum of exhaust and crankcase 

emission factors.

Based on the engine specification sheet provided in Appendix G-3.

Operating time for this engine has been assumed to be 100 hrs/year. 

Anadarko is proposing the use of Ultra Low Sulfur Diesel for all diesel combustion sources. Therefore, emissions 

have been calculated based on a maximum sulfur content of 15 ppm in diesel fuel assuming that 98 percent of sulfur 

in the fuel is oxidized to SO2 and 2 percent of sulfur in the fuel is oxidized to H2SO4 based on Draft Regulatory 

Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003. 

Based on footnote b of AP-42 Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and Diesel 

Industrial Engines (October 1996). Per footnote b of Table 3.3-1, all PM is assumed to be < 1 um, therefore, 

assumed PM2.5 = PM10 = PM. 

Emission factors are based on AP-42, Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and Diesel 

Industrial Engines (October 1996). Emission factors for diesel fuel are used.

Lead emission factor was obtained from EPA guidance document: Locating and Estimating Air Emissions from Sources 

of Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor for distillate oil-fired gas 

turbines was used as a surrogate for distillate oil-fired engines due to lack of emission factors. An average brakespecific fuel consumption (BSFC) of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr.

All TOC is assumed to be VOC. TOC emission factor has been calculated as the sum of exhaust and crankcase emission 

factors.

fuel is oxidized to SO2 and 2 percent of sulfur in the fuel is oxidized to H2SO4 based on Draft Regulatory Impact Analysis: 

Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003. 

Based on footnote b of AP-42 Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and Diesel Industrial 

Engines (October 1996). Per footnote b of Table 3.3-1, all PM is assumed to be < 1 um, therefore, assumed PM2.5 = PM10 = 

PM. 

Emission factors are based on AP-42, Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and Diesel 

Industrial Engines (October 1996). Emission factors for diesel fuel are used.
