Dwight,

It was recommended that we consult with Indian tribes within 50 km of the MCU site. This includes both the Navajo

Nation reservation, as well as the Ute Mountain Indian reservation. Therefore, please also include applicable historic

properties on the Ute Mountain Reservation land in the assessment for the MCU site. Below is the contact information I

currently have for the Ute Mountain THPO.

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-rich2 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.
