Basis (within 25 miles of Drilling Location and one location per 180-day campaign)

Emissions are generated from the combustion of diesel fuel in engines associated with support vessels that will operate within 25 miles of the drilling rig. The support vessels include 1) crewboats and 2) offshore support vessels, which both transport personnel and supplies to and from the drilling rig.Annual emissions are calculated using the average power rating, length of the drilling campaign and emission factors, which are based on engine size and its applicable regulations. Criteria, Greenhouse Gas and Hazardous Air Pollutants 

emission factors for each engine and pollutant are referenced below. Additionally, example calculations are provided below.

The Transocean Discoverer Americas has a diesel-fired cargo tank heater system, which circulates heated thermal fluid through the cargo tanks to maintain a specified temperature. The system has never been continuously operated, Transocean tests the system twice per year (~1hr/test). The thermal heater manufactuer is Aalborg Industries, the model V5-0-TFO-040 with a Weishaupt R11 burner.Annual emissions are calculated based on 13.6 MMBtu/hr heat input rate and 1 hour of operation per 180 day drilling campaign in conjunction with AP-42 emissions factors for fuel oil combustion (AP-42 Sections 1.3, May 2010).

2 Light oil components are those components servicing material in a liquid state in which the sum of the concentration of individual constituents with a vapor pressure exceeding 0.05 psi

 at 20°C (or 68° F) is greater than or equal to 20% by weight.

3 Heavy liquid components are those components that are not gas or light oil components. Diesel is considered a Heavy Oil because the vapor pressure of diesel at 68° F is 0.009 psi, which is

 less than 0.05 psi at 68°F.

4 Water / Oil applies to streams with a water content greater than 50%, but less than 99%.5 Others includes compressors, drains, dump arms, hatches, instruments, meters, and pressure relief valves.6 Emission factors from Table 2-4, Oil and Gas Production Operations Average Emission Factors from the EPA Protocol for Equipment Leak Emission Estimates document,

 EPA-453/R-95-017 November 1995. The Light Oil factor is used for all pumps. The worst case factor from flanges and connectors is used for flanges/connectors. The Heavy Oil factor for Other was used since the large majority of components are in diesel service.

The Transocean Discoverer Americas drilling rig is equipped with tanks or storage vessels for storage of diesel fuel, aviation fuel, and waste oil. The engines burn Marine diediesel fuel). Jet naphtha is used to estimate emissions for aviation fuel. Distillate fuel oil No. 2 is used for the waste oil tanks, although the waste oil is expected to be much Emissions from storage vessels are estimated using EPA's TANKS 4.0.9d Program. Emission estimates account for refueling emissions as well as normal breathing losses fThe size and throughput for each storage vessel on board is indicated below.

Drilling mud is used during the drilling process to lubricate and cool the drill bit and transport drill cuttings. During the drilling propassing through a hydrocarbon zone, hydrocarbons entrained in the drilled material will be carried to the surface with the mud. Wthe surface it is exposed to the atmosphere and the entrained gas, which can be hydrocarbons flashes out of the mud to the atmcome from any of the drilling mud equipment including the Shaker Room, Mud Pits or Mud Tanks, etc.

Based on this calculation, emissions are assumed to be minimal. Since all sulfur in the fuel

is conservatively assumed to be converted to SO2, sulfuric acid mist emissions are not included

elsewhere in the permit application.

Sulfuric Acid Mist (Sulfate PM - SO4) was calculated using the methodology in the "Draft Regulatory 

Impact Analysis: Control of Emissions from Nonroad Diesel Engines" (EPA 420-R-03-008). Based on 

Chapter 3 of this EPA document, an average of 2.247% of the sulfur in diesel fuel burned is converted 

to sulfate (SO4).

elsewhere in the permit application.

Total Reduced Sulfur (including reduced sulfur compounds) was calculated using the methodology in 

the "Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines" (EPA 420-

R-03-008). It is assumed that an average of 1% by weight of sulfur in converted to other compounds. 

An assumed MW of 150.31 lb/lb-mole is used to over-estimate the emissions based on all total 

reduced sulfur compounds composed of dipropyl disulfide (C6H14S2).

Example Vessel Name Engine Description Manufacturer

Emissions are generated from the combustion of diesel fuel in engines associated with support vessels that will operate within 25 miles of the drilling rig. The support vessels include 1) crewboats and 2) offshore support vessels, which both transport personnel and supplies to and from the drilling rig. Annual emissions are calculated using the average power rating, length of the drilling campaign and emission factors, which are based on engine size and its applicable regulations. Criteria, Greenhouse Gas and Hazardous Air 

Pollutants emission factors for each engine and pollutant are referenced below. Additionally, example calculations are provided below.

1 Gas components are those components servicing material in a gaseous state at operating conditions.2 Light oil components are those components servicing material in a liquid state in which the sum of the concentration of individual constituents with a vapor pressure exceeding 0.05 psi

 at 20°C (or 68° F) is greater than or equal to 20% by weight.

3 Heavy liquid components are those components that are not gas or light oil components. Diesel is considered a Heavy Oil because the vapor pressure of diesel at 68° F is 0.009 psi, which is

 less than 0.05 psi at 68°F.

4 Water / Oil applies to streams with a water content greater than 50%, but less than 99%.5 Others includes compressors, drains, dump arms, hatches, instruments, meters, and pressure relief valves.6 Emission factors from Table 2-4, Oil and Gas Production Operations Average Emission Factors from the EPA Protocol for Equipment Leak Emission Estimates document,

 EPA-453/R-95-017 November 1995. The Light Oil factor is used for all pumps. The worst case factor from flanges and connectors is used for flanges/connectors. The Heavy Oil factor for Other was used since the large majority of components are in diesel service.

The Maersk Developer drilling rig is equipped with tanks or storage vessels for storage of diesel fuel, aviation fuel, and waste oil. The engines burn Marine diesel fuel (No. 2 diesel fuel). 

Jet naphtha is used to estimate emissions for aviation fuel. Distillate fuel oil No. 2 is used for the waste oil tanks, although the waste oil is expected to be much heavier. Emissions from storage vessels are estimated using EPA's TANKS 4.0.9d Program. Emission estimates account for refueling emissions as well as normal breathing losses from the tanks. The size and throughput for each storage vessel on board is indicated below.

Drilling mud is used during the drilling process to lubricate and cool the drill bit and transport drill cuttings. During the drilling process whpassing through a hydrocarbon zone, hydrocarbons entrained in the drilled material will be carried to the surface with the mud. When ththe surface it is exposed to the atmosphere and the entrained gas, which can be hydrocarbons flashes out of the mud to the atmospheremay come from any of the drilling mud equipment including the Shaker Room, Mud Pits or Mud Tanks, etc.

98.08 lb/lb-mol, molecular weight of H2SO4

27.07 lb/yr, annual H2SO4 produced

0.014 ton/yr, annual H2SO4 produced

Based on this calculation, emissions are assumed to be minimal. Since all sulfur in the fuel

is conservatively assumed to be converted to SO2, sulfuric acid mist emissions are not included

elsewhere in the permit application.

Sulfuric Acid Mist (Sulfate PM - SO4) was calculated using the methodology in the "Draft Regulatory 

Impact Analysis: Control of Emissions from Nonroad Diesel Engines" (EPA 420-R-03-008). Based on 

Chapter 3 of this EPA document, an average of 2.247% of the sulfur in diesel fuel burned is converted 

to sulfate (SO4).

Based on this calculation, emissions are assumed to be minimal. Since all sulfur in the fuel

is conservatively assumed to be converted to SO2, TRS emissions are not included

elsewhere in the permit application.

Total Reduced Sulfur (including reduced sulfur compounds) was calculated using the methodology in 

the "Draft Regulatory Impact Analysis: Control of Emissions from Nonroad Diesel Engines" (EPA 420-

R-03-008). It is assumed that an average of 1% by weight of sulfur in converted to other compounds. 

An assumed MW of 150.31 lb/lb-mole is used to over-estimate the emissions based on all total 

reduced sulfur compounds composed of dipropyl disulfide (C6H14S2)
