Dear Mr. Natchees:

The U.S. Environmental Protection Agency Region 8 is proposing to issue a synthetic minor permit for the KGH Operating Company (KGH), Bonanza State 20-15H Compressor Station on the Uintah and Ouray Indian Reservation. As requested by KGH, this permit authorizes the construction and operation of new emission sources, specifically a 1.0 million standard cubic foot per day triethylene glycol (TEG) dehydration unit. The TEG dehydration unit would be constructed inside an existing building within the existing footprint of the facility. The permit also authorizes the removal of one of the permitted compressor engines currently operating at 20-15H and the removal of an unpermitted jet pump engine. This permit also maintains previously established enforceable emissions restrictions for existing installed and operating emissions units and associated voluntarily installed and operated control devices.

A public comment period for the proposed permit will begin on July 16, 2020, and end on August 17, 2020.

The proposed permit and supporting documentation are available in the electronic docket at Regulations.gov (Docket ID #EPA-R08-OAR-2020-0192), and we ask that you please assist members of the public who contact you with instructions on how to access the material available for public review until the end of the public comment period. Comments may be submitted by mail, via email to R8AirPermitting@epa.gov or through regulations.gov (Docket ID #EPA-R08-OAR-2020-0192). All of these documents will also be available for review in electronic format on our website at: https://www.epa.gov/caa-permitting/caa-permit­ public-comment-opportunities-region-8.
                                          
                                          
                                          
                                          
                                          
                                          
                                          
                                          
                                          
                                          

If you have any questions concerning the proposed permit or technical support documents, please contact Colin Schwartz, of my staff, at (303) 312-6043.
