Southern Energy Operating LLC, Burnside Facility (“Burnside”), located at Off Highway 433,  in Satartia, MS, (587) 287-5406, has applied to the Mississippi Department of Environmental Quality (MDEQ) for the following permitting action(s): Reissuance of Synthetic Minor Operating Permit (SMOP) Air Ref. No. 3020-00058. The applicant's operations fall within SIC Code 1311.  A Statement of Basis has been prepared that contains a discussion of the decision-making that went into the development of the permit and provides the permitting authority, the public, and other government bodies a record of the technical issues surrounding issuance of the permit. The Statement of Basis also addresses any changes to emissions and/or discharges resulting from any modification of the facility.  
Burnside is an existing natural gas treatment plant with an adjacent well pad. The adjacent well pad produces sweet natural gas and liquids. Burnside routes the sweet gas and liquids to three phase separators via a line heater. The facility stores the separated liquids in tanks (Emission Points AB-011 and AB-012) until hauled off site while the separated gas is sent to the treatment plant.
The separated gas typically contains carbon dioxide (CO2) and water, which must be removed for the gas to meet sales requirements. The permittee compresses the gas with a natural gas-fired engine and transports the gas through a line heater before treatment. The gas is treated by the amine unit (Emission Points AB-005, AB-016, and AB-018) and one or both dehydration units (Emission Points AB-021 and AB-022) to remove CO2 and water, respectfully. Next, a Low-Pressure Separator (Emission Points AB-023 and AB-024) extracts more gas from the mixture. The SMOP requires Emission Points AB-011, AB-012, AB-016, AB-018, AB-021, AB-022, AB-023, and AB-024 to route all emissions to an on-site control flare (Emission Point AB-020). The facility is a source of Particulate Matter (PM), PM less than 10 micrometers in diameter, PM less than 2.5 micrometers in diameter, Sulfur Dioxide, Carbon Monoxide, Volatile Organic Compounds (VOC), and Hazardous Air Pollutant (HAP) emissions.
Burnside has the potential to exceed the Title V major source threshold of 100 tons per year (tpy) for VOC, Individual HAP, and Total HAP emissions. Emission Points AB-011, AB-012, AB-016, AB-018, AB-021, AB-022, AB-023, and AB-024 are required to route all emissions to Emission Point AB-020 for control which will allow controlled emissions to remain below the Title V threshold. The facility is requesting a facility-wide VOC, Individual HAP, and Total HAP emission limitations to remain below the Title V threshold and will demonstrate compliance via monitoring and recordkeeping. The facility does not have the potential to exceed the Prevention of Significant Deterioration (PSD) threshold of 250 tpy for any regulated pollutant. The facility is a minor source under the PSD program.
