VIEW ATTACHMENTS FOLLOWING PUBLIC NOTICE
The LDEQ, Office of Environmental Services, is accepting written comments on minor source air operating permit modification for Gulfport Energy Corpration, 14313 N May Ave, Ste 100, Oklahoma City, OK, 73134 for the West Cote Blanche Bay Facility. The facility is located 5 miles southeast of Cypremort Point, 6 miles south of Cote Blanche Island and 6.56 miles east southeast of Louisa, St. Mary Parish.
Gulfport Energy Corporation requested a minor source air operating permit modification for West Cote Blanche Bay Facility, an existing oil and gas production facility. Productions from the nearby wells flow to a low-pressure separator. Gas from the low-pressure separaror is picked-up by facility compressors and piped directly to the gas dehydration unit. Dehydrated/pressured gas is routed to sales and/or gas-lift and platform fuel. The liquids (condensate/oil and produced water) flow through a free-water knock system prior to the facility heater treaters. Flash losses due to the pressure drop between the L.P separators and the heater treaters are routed to the heater treater vent. Heater treater vent gas is VRU controlled and routed back to facility's low-pressure system. Produced water separated out of the L.P separator/free-water knock is routed to a 1500 BBL Produced Water Tank (Source T-04). Condensate/crude oil and trace amounts of water are sent to the two heater treaters for further separation. Condensate/crude oil is then piped to one of the two storage tanks. Produced water from the heater treater is also piped to the Produced Water Tank (Source T-04). Emissions from the Heater Treater Vent and from oil storage and slop oil tanks are routed to the Vapor Recovery Unit (VRU). Dry gas from the Glycol Dehydration Unit is sent to sales pipeline and facility fuel gas system.
The stored condensate/crude oil is transferred from the storage tanks to a storage barge. Any oil recovered from the produced water tank is also sent to the oil storage tanks. Flash, standing and working losses are vented to the VRU. Oil is transferred from the oil storage barge to a transportation barge using a diesel powered pump. The oil is then shipped to sales. Produced water from the Produced Water Tank is transported by salt-water disposal pumps to disposal wells. Any oil recovered from the produced water tank is sent to the Slop Oil Tank.
A Public Notice is issued for the facility due to the high volume of VOC and NOX emissions, which are very close to the major source threshold limits.
Estimated emissions from this facility in tons per year are as follows:
