### Jeremy,
I appreciated the opportunity to speak with you on Wednesday regarding our project and Dinetahdoo’s ability to help us move it forward.

As we discussed, Resolute needs a National Historic Preservation Act compliance evaluation for the McElmo Creek Unit (MCU) Main Flare. The evaluation is necessary for our pending PSD air permit application with US EPA Region 9.
The flare is located at the MCU central compressor station, approximately 3.5 miles northwest of Aneth, Utah. The flare has been operated by Resolute Natural Resources Company, LLC (Resolute) since 2006. The MCU field is an enhanced (tertiary) oil recovery project and has been operated using CO2 water-alternating gas (WAG) injection since the mid-1980s. The MCU central compressor station receives CO2-rich produced gas from producing wells within MCU through a series of satellite headers and tank batteries. The CO2-rich produced gas is compressed by the facility’s electrically driven compressors and reinjected into the producing reservoir through a series of WAG headers and injection wells. The flare combusts gas that must be vented due to compressor downtime or periods when CO2 breakthrough causes produced gas volumes to exceed compressor capacity.
I have attached a set of maps showing the location of the McElmo Creek Unit Main Flare.
Please let me know if you need more information and pr ovide a cost estimate and anticipated schedule at your earliest convenience. In addition to my contact informat ion, I have included the project contacts for US EPA and the Navajo Nation HPD below.
