Denbury Onshore LLC, Martinville EOR Facility, located at 327 Coho Drive in Mendenhall, MS, (601) 847-3833, has applied to the Mississippi Department of Environmental Quality (MDEQ) for the following permitting action(s): Synthetic Minor Operating Permit Modification, Air Ref. No. 2480-00068. 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.  
The facility is located in the Martinville Oil and Gas Field and used as a central processing site for oil and gas operations associated with this field. The basis of the oil recovery process hinges around a tertiary recovery technique that utilizes CO2 injection to produce the crude oil. CO2 will be pressurized to a liquid state and then injected into the formations. The properties of the CO2 under these conditions enable it to permeate through the formations to break free oil remaining in these reservoirs that would likely not flow to the surface under primary or secondary recovery methods
Denbury has applied for a modification to their Synthetic Minor Operating Permit (SMOP) that will add truck loading (Emission Point AA-023) and will account for emissions from the truck loading process. Denbury currently routes all oil captured to a Lease Automated Custody Transfer (LACT) line for sale. However, upon issuance of this permitting action, the company that currently owns the LACT line will be decommissioning it and Denbury will need to transfer all collected oil to transfer trucks for sale. Denbury has requested the operational flexibility to send oil to a LACT line should the line be reopened in the future.
Denbury has the potential to exceed the Title V threshold for both Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs). In order to qualify as a Synthetic Minor Source, Denbury has opted to take limitations on VOC emissions as well as individual and total HAPs by routing the produced gas to the process control flares.
