6, 2010 United States Environmental Protection Agency 75 Hawthorne Street San Francisco, California 94105 Dear Mr. Rios: Resolute Natural Resources Company, LLC (Resolute) appreciated the opportunity

to meet last week with you, Mr. Mintz, and members of your staff to discuss our operations

at the McElmo Creek Unit (MCU), including our plan to install additional equipment
to further improve facility efficiency and reduce emissions. We also expressed our desire to complete the Prevention of Significant Deterioration (PSD) and Operating permits for the MCU Main Flare,
a process begun by our predecessor ExxonMobil over five years ago, so that we may terminate the MCU consent decree. As discussed, Resolute plans to replace the existing dehydrator

at the MCU facility with a new triethylene glycol dehydration unit controlled by a thermal oxidizer (the dehydrator)

to further improve compressor reliability and reduce flare-related emissions. Attached
to this letter is output from the GRI GlyCalc model estimating controlled emissions of volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) associated with the dehydrator. The model output confirms the controlled emissions are below significance thresholds for VOCs and HAPs, comprising 4.4 tons per year (tpy) VOCs, 2.2 tpy total HAPs, and 0.8 tpy benzene. We understand from comments made by you and Mr. Mintz that the EPA's position
is that the new dehydrator can be added to the facility prior to issuance of the PSD and Operating permits, provided Resolute can do so without exceeding emission limits contained
in the consent decree, or significance thresholds for PSD modifications. We confirm to you that neither the emission limits of the consent decree nor the significance thresholds for PSD modifications will be exceeded
as a result of adding the new dehydrator. Given the six month lead time required for delivery and on the basis of the EPA's position, we will proceed to order the dehydrator
in February 2011 and plan to install and operate the unit by the third quarter of2011. Resolute Natural Resources Company, LLC 1675 Broadway
