VIEW ATTACHMENTS FOLLOWING PUBLIC NOTICE

The LDEQ, Office of Environmental Services, is accepting written comments on the proposed synthetic minor air operating permit modification for Apache Corporation, 2014 W Pinhook Road, Suite 800, Lafayette, LA 70508 for their East Mud Lake Facility. The facility is located northeast of Mud Lake, east of Highway 27, 31.8 miles south from Sulphur, and approximately 4 miles northeast from Holly Beach, in Cameron Parish.
 
Apache Corporation requested a permit modification for the East Mud Lake Facility, a typical oil and gas production facility used to treat and handle production from the Mecom A-1, Fina Fee #2 #1, Lutcher C-1, Mecom A-11, Lutcher C-7, and Mecom A-3 well completions. Production from the wells is routed to individual high-pressure (HP) separators. Gas from these separators is commingled, compressed, and then discharged to a glycol contact tower for drying prior to being sold by pipeline and used for facility fuel. Oil from the HP separators is routed to a bulk heater treater for further separation Water from the HP separators is routed to a gun barrel tank to separate any remaining oil. Water from this tank flows to a suction tank and is eventually pumped (via gas-fired SWD pumps) to an injection well for disposal and oil is routed to a skim oil tank. Oil from the heater treater is routed to on-site tanks for storage until hauled by tank truck for sales. Vapors from the glycol still column are piped through a condenser where the condensed liquids are collected by a blowcase vessel and effluent vapors are routed to the firebox of the glycol burner for fuel. The glycol dehydration system is equipped with a glycol pump flash separator where off-gas is also routed to the firebox of the burner for fuel with relief gas released to atmosphere through the skim oil tank. Various catalytic heaters, gas operated pumps & insignificant storage tanks are also located at this facility.
 
Apache Corporation proposes the following in this modification:
 
1)      Remove a SWD pump (EPN 61-06-ICE-ES)
2)      Add a glycol pump flash separator relief vent (EPN 88-08-GPFS-RV), two SWD pumps (EPNs 89-08- ICE-ES & 90-08-ICE-ES), and a gas operated pump (EPN 91-08-GOP)
3)      Replace a gas compressor engine (EPN 2E-91) with another gas compressor engine (EPN 92-09-ICE-ES).
 
Federally enforceable conditions were added for the gas-operated pumps.
