[8] 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 SO 2 and 2 percent of sulfur in the fuel is oxidized to H 2 SO 4 based on Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003.

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 SO 2 and 2 percent of sulfur in the fuel is oxidized to H 2 SO 4 based on Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel En g ines , EPA420-R-03-008 , A p ril 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). PM 10 and PM 2.5 emission factors obatined by applying the ratio of PM/PM 10 and PM/PM 2.5 from AP-42 Chapter 3, Table 3.4- 1 and Table 3.4-2 on EPA Tier II PM emission factor.

An average BSFC of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr to calculate emissions. CH 4 , CO 2 and N 2 Oare included in the emissions of CO 2 equivalent (CO 2 e), 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). Operating time for this engine has been assumed to be 1 hr/day and 100 hrs/year.

### 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 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. 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 SO 2 

### and 2 percent of sulfur in the fuel is oxidized to H 2 

### SO 4 

### 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). PM 10 

### and PM 2.5 

### 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 PM 2.5

### 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-firedgas 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 SO 2

Per footnote b of Table 3.3-1, all PM is assumed to be < 1 um, therefore, assumed PM 2.5 = PM 10 = 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 gasturbines 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.

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 PM 2.5 

### = PM 10 

### = 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 SO 2 

### and 2 percent of sulfur in the fuel is oxidized to H 2 

### SO 4 

### based on Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003.

Note: [1] For all diesel tanks on the drillship, the annual "capped" emissions of all the diesel tanks grouped together are calculate d 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% sa fety factor)

[4] For all three jet fuel tanks, throughput is 450 GPD based on the email from Ms. Sara Carlson (Anadarko) to Rahul Pendse (Tr inity) 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 4.0 9d 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 drillshi p 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.

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 a verage 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.

### Criteria Pollutants and Sulfuric Acid

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 oil-fired gas turbines was used as a surrogate for distillate oil-fired engines due to lack of emission factors. An average brake-specifi c 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 SO 2 and 2 wt.% of sulfur in the fuel is oxidized to H 2 SO 4 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 PM 2.5 and PM 10 are calculated based on ratio of PM/PM 2.5 and PM/PM 10 which are obtained from AP-42 Chapter 3, Table 3.4-2.

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.

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 (for all supply boats combined). 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 SO 2 and 2 wt.% of sulfur in the fuel is oxidized to H 2 SO 4 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 PM 2.5 and PM 10 are calculated based on ratio of PM/PM 2.5 and PM/PM 10 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. Per footnote f of AP-42 Chapter 3, Table 3.4-1, non methane VOC emission factor is 91% of TOC emission factor.

All TOC is assumed to be VOC. TOC emission factor has been calculated as the sum of exhaust and crankcase emission factors. Engine rating is based on EPA Region 4 Permit No. OCS-EPA-R4005-M1. Operating time for this engine is conservatively assumed to be 1 hrs/day, 100.0 hrs/year. 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 SO 2 

### and 2 wt.% of sulfur in the fuel is oxidized to H2SO4 b ased on Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003. Per Caterpillar C9 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. VOC emission factors is 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. Per footnote b of Table 3.3-1, all PM is assumed to be < 1 um, therefore, assumed PM 2.5 

### = PM 10 

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

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 SO 2 and 2 percent of sulfur in the fuel is oxidized to H 2 SO 4 based on Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003.

Emission factor for distillate oil-firedgas 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 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 SO 2 and 2 percent of sulfur in the fuel is oxidized to H 2 SO 4 based on Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003.

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 SO 2 and 2 percent of sulfur in the fuel is oxidized to H 2 SO 4 based on Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003.

[7] 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-firedgas 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 SO 2 and 2 percent of sulfur in the fuel is oxidized to H 2 SO 4 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.

Pollutant Emission Factor Basis Emission Factor

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 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 consumpti on (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 Specification Obtained from Caterpillar website for C280-8 Engine as a representative stimulation vessel main engine.

Operating information provided by Mr. Aaron Wade and Ms. Sara Carlson (Anadarko) on October 22, 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 SO 2 and 2 percent of sulfur in the fuel is oxidized to H 2 SO 4 based on Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003. Based on Engine Specification obtained from Manufacturer's website for C280-8 Engine which is certified to IMO Tier II/EPA Marine Tier II (Table A-1 of 40 CFR 94.8(a)(2)(i)). Engine displacement is 148L as per engine specification. http://catoilandgas.cat.com/cda/files/2180159/7/C280-8%2050%20Hz%20LEHW0086-02%20P2.pdf PM 10 and PM 2.5 emission factors obtained by applying the ratio of PM/PM 10 and PM/PM 2.5 from AP-42 Chapter 3, Table 3.4-1 and Table 3.4-2 on EPA Tier II PM emission factor

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. Representative thrusters for the stimulation vessel. Operating information provided by Mr. Aaron Wade and Ms. Sara Carlson (Anadarko) on October 22, 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 SO 2 and 2 percent of sulfur in the fuel is oxidized to H 2 SO 4 based on Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines, EPA420-R-03-008, April 2003. PM 10 and PM 2.5 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 PM 2.5 . 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 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.
