Dear Ms. Haskins:

The U.S. Environmental Protection Agency Region 8 is proposing to issue a synthetic minor permit for the Merit Energy Company (Merit), Steamboat Butte C1/C3 Tank Battery on the Wind River Indian Reservation. As requested by Merit, this permit is only intended to establish requested enforceable emissions restrictions for existing installed and operating emissions units and associated voluntarily installed and operated control devices. Merit requested legally and practicably enforceable requirements for the installation and operation of two flares to control the volatile organic compound (VOC) emissions from produced natural gas from a heater treater separator and flashing, working and breathing loss emissions from crude oil storage tanks and produced water storage tanks. Merit has also requested to limit facility oil, produced water, natural gas throughput and the sulfur content in flared gas, as hydrogen sulfide. This permit would not authorize the construction of any new emissions sources or emissions increases from existing units, nor would it otherwise authorize any other physical modifications to the facility or its operations. 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 December 21, 2018, and end on January 22, 2019. 

We have enclosed paper copies of 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 via mail, via email to R8AirPermitting@epa.gov, or through https://www.regulations.gov (Docket ID # EPA-R08-OAR-2018-0339). In addition, we have provided copies of the bulletin board public notice announcement and would appreciate it if you could 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 Christopher Razzazian, of my staff, at (303) 312-6648.   

						Sincerely,
