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.

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 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. Operating time for this 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. 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. 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. 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 emission factors. An average brake-specific fuel consumption (Brake Specific Fuel Consumption (BFSC)) of 7,000 Btu/hp-hr is used to convert from lb/MMBtu to lb/hp-hr.

### 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 this 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 . Total particulate emissions is the sum of filterable and condensable particulate emissions.

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

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.

[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.

[8] 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 Emissionsfrom 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 (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.

[8] Per footnote f of AP-42 Chapter 3, Table 3.4-1, non methane VOC emission factor is 91% of TOC emission factor. Based on EPA Region 4 Permit No. OCS-EPA-R4005-M1. Operating time for this engine is conservatively assumed to be 24 hrs/day, 200 days/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 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 C9 DITA Specifications, displacement of each cylinder is 2.5-5 L/cylinder which is less than or equal to5L/cylinder. Therefore, according to 40 CFR 94.8(a)(2)(i), the emission factors of NOx, PM and CO are 7.2, 5 and 0.2 g/kWhr 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 Emissionsfrom 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.

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. 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. 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 .

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 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.
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 (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-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.

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.

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.

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.

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. 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.

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.
