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

is conservatively assumed to be converted to SO 2 

# , sulfuric acid mist emissions are not included

elsewhere in the permit application. Sulfuric Acid Mist (Sulfate PM - SO 4 

# ) 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 (SO 4

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 (C 6

Diesel is considered a Heavy Oil because the vapor pressure of diesel at 68° F is 0.009 psi, which isless than 0.05 psi at 68°F.4Water / Oil applies to streams with a water content greater than 50%, but less than 99%.5Others includes compressors, drains, dump arms, hatches, instruments, meters, and pressure relief valves.6Emission 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 Oilfactor for Other was used since the large majority of components are in diesel service.7Speciation for Diesel Fuel based on the composition of diesel from EPA's TANKS 4.0.9d program.Total VOC EmissionsServiceServiceValvesDiesel Fuel7ValvesTotal EmissionsServiceFlanges/ConnectorsFlanges/ConnectorsEmission FactorsFlanges/ConnectorsValvesPumpsPollutants Wt%Other5Other5PumpsOther5PumpsFugitive EmissionsPage 9 of 15ENVIRON International CorporationStatoilEastern GOM OCS Air Permitting ProjectMaersk Developer Emission CalculationsStorage Tank Emissions CalculationsFuel Oil Tank InventoryCapacity CapacityWorkingCapacityThroughput(m3) gal gal (gal/yr)Pontoon Fuel Oil Tank No.1FO 01 PS Pontoon - PORT Storage 1,305 344,715 310,244 700,000Pontoon Fuel Oil Tank No.2FO 02 SB Pontoon - STBD Storage 1,305 344,715 310,244 700,000Pontoon Fuel Oil Tank No.3FO 03 PS Pontoon - PORT Storage 875 231,087 207,978 700,000Pontoon Fuel Oil Tank No.4FO 04 SB Pontoon - STBD Storage 875 231,087 207,978 700,000Upper Hull Fuel Oil Tank No.1FO 05 PS Hull - PORT Service/Day 49 12,815 11,533 1,400,000Upper Hull Fuel Oil Tank No.2FO 06 SB Hull - STBD Service/Day 57 14,952 13,457 1,400,000Upper Hull Fuel Oil Tank No.3FO 07 PS Hull - PORT Settling 34 8,948 8,053 1,400,000Upper Hull Fuel Oil Tank No.4FO 08 SB Hull - STBD Settling 35 9,230 8,307 1,400,000Emerg.
