Mr. Gerardo C. Rios, PE Chief~, Permits Office AirDivision United States Environmental ProtectionAgency 75 Hawthorne Street San Francisco, California 94105

Dear Mr. Rios:
Resolute Natural Resources Company, LLC (Resolute) appreciatedthe opportunityto meet lastweekwith you, Mr. Mintz, and members ofyourstaffto discuss ouroperations atthe McElmo Creek Unit (MCU), including ourplanto install additional equipmentto further improve facility efficiencyand reduce emissions. We also expressedourdesireto completethe Prevention ofSignificant Deterioration (PSD) and Operating permits forthe MCU Main Flare, a process begun byourpredecessor ExxonMobil overfive years ago, sothatwe mayterminatethe MCU consentdecree.
As discussed, Resolute plansto replacethe existing dehydratoratthe MCU facilitywith a newtriethylene glycol dehydration unit controlled byathermal oxidizer (the dehydrator) to further improve compressorreliabilityand reduce flare-related emissions. Attached to this letter is outputfrom the GRI GlyCaic model estimating controlled emissions ofvolatile organic compounds (VOC5) and hazardous airpollutants (HAPs) associatedwiththe dehydrator. The model outputconfirmsthe controlled emissions are belowsignificancethresholds forVOCs and HAPs, comprising 4.4tons peryear (tpy) VOCs, 2.2 tpytotal HAPs, and 0.8 tpy benzene.
We understand from comments made byyou and Mr. Mintzthatthe EPA’s position is thatthe newdehydratorcan be addedto the facilitypriorto issuance ofthe PSD and Operating permits, provided Resolute can do sowithout exceeding emission limits contained inthe consent decree, orsignificance thresholdsfor PSD modifications. We confirmto youthat neitherthe emission limits ofthe consentdecree northe significancethresholds for PSD modifications will be exceeded as a resultofadding the newdehydrator. Giventhe six month leadtime required fordelivery and onthe basis ofthe EPA’s position, we will proceedto orderthe dehydrator in February2011 and plan to install and operatethe unit bythethird quarterof2011.

## Overthe course ofthe nextfewweeks, Resolutewill provide youroffice withthe

following information requested during ourmeeting, in further supportofour long-pending PSD permit application:

An updated BestAchievable Control Technology (BACT) analysisto documentthe steps alreadytaken by Resoluteto increase compressorefficiency and reduceflaring; Reviewand possibly updatethe airquality model previously submittedto EPAto address the facility’s modeled compliance with recently adopted one-hour SO2 standard; A demonstrationthatgreenhouse gas emissions atthe MCU facility are below75,000 tons ofCO2 equivalents peryear; and, Reviewand update, ifappropriate, the Class I Area Impacts and Endangered Species sections ofthe pending PSD application.

Thankyou again foryourtime and consideration. Resolute and Navajo Nation Oil and Gas Company remain committedto working withthe EPAto obtain PSD andTitle V permits andterminatethe MCU consentdecree as quickly as possible. We plantovisityouroffice again in early February2011 to furtherfacilitatethe process and address anyremaining questions, commentorconcerns. Please letus knowinthe meantime ifyou need anyother information or ifwe can assistyou in expeditingthe process in anyway.
Sincerely,
