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 would incorporate enforceable requirements for the installation and operation of two field gas fired, 4-stroke, rich-burn compressor engines using catalytic emissions control systems. KGH also requested enforceable requirements to install and operate two flares to control volatile organic compounds from the two separators and six storage tanks on site, as well as a throughput limit on flared gas. This permit is only intended to incorporate requested emission limits and provisions from the permit application for existing emissions units operating at the facility.

A public comment period for the proposed permit will begin on August 6, 2019, and end on September 4, 2019.

We have enclosed a CD and paper copy containing the proposed permit and supporting documentation, and we ask that you please make this 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-2018-0342). In addition, we have provided copies of the bulletin board public notice announcement and would appreciate it if you would post this announcement in prominent locations in your area. 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 enclosed proposed permit or technical support documents, please contact Patrick Wauters, of my staff, at (303) 312-6114.
