Re: Draft Part 71 Operating Permit, #V-UO-000020-2007.00, Cobra Oil and Gas Corporation, Flat Rock Compressor Station

Dear Mr. Winters:

The U.S. Environmental Protection Agency Region 8 has completed its review of Cobra Oil and Gas Corporation's (Cobra's) application for the Flat Rock Compressor Station to obtain an initial Clean Air Act Title V operating permit pursuant to the Title V Operating Permit Program at 
40 CFR part 71 (Part 71). 

Enclosed are the draft permit and the corresponding Statement of Basis. The regulations at 
40 CFR 71.11(d) require that an applicant, the public and affected states (as defined in 40 CFR 71.2) have the opportunity to submit written comments on any draft Part 71 operating permit. All written comments submitted within 30 calendar days after the public notice is published will be considered by the agency in making its final permit decision. Enclosed is a copy of the public notice which will be published on the EPA's website located at: https://www.epa.gov/caa-permitting/caa-permit-public-comment-opportunities-region-8, on August 22, 2018. The public comment period will end at 
5:00 p.m. MDT on September 21, 2018.   
      
The conditions contained in the permit will become effective and enforceable by the agency if the permit is issued final. If you are unable to accept any term or condition of the draft permit, please submit your written comments, along with the reason(s) for non-acceptance to:
