McELMO CREEK UNIT OIL PRODUCTION FACILITY

REQUEST FOR PUBLIC COMMENT UNDER
SECTION 106 OF THE NATIONAL HISTORIC PRESERVATION ACT

On October 15, 2014, the United States Environmental Pr otection Agency (EPA) Region 9 proposed to amend the Prevention of Significant Deteriorat ion (PSD) permit, in accordance w ith PSD air quality regulations (40 CFR 52.21), for the McElmo Creek Unit Oil Production Fa cility (MCU Facility), an existing oil and gas production operation. The MCU Facility is owned, in partnership with the Na vajo Nation Oil and Gas Company, and operated by the Resolute Natural Resources Company. The f acility is located in Section 31, Township 40 South, Range 25 East within the Four Co rners Area on the Navajo Na tion Reservation near the town of Aneth, San Juan County, Utah.

EPA’s proposed amendments to the PSD permit include adding pollution limits, terms and conditions for the already existing Main Flare at the MCU Facility pursuant to a federal Consent Decree (United States v. Mobil Exploration and Producing U.S. Inc., Case No. 2:05-CV-319, filed June 8, 2005). These pollution limits, terms
and conditions include Best Available Control Tec hnology emission limitations for nitrogen oxides, carbon monoxide, sulfur dioxide, and volatile organic compounds for the Main Flare at the MCU Facility. Additionally, EPA is amending the permit to remove certain equipment, and the applicable permit requirements that apply because this equipment has been shut down and removed from the site. Other than the potential replacement of the fan on the Main Flare to provide better pollution control, this permit action does not authorize any new construction or modificati on of existing equipment at the MCU Facility.

In accordance with Section 106 of the National Histor ic Preservation Act (NHPA) and the implementing regulations at 36 CFR 800, EPA is seeking public co mment on the October 15, 2014, proposed permit action’s potential to directly (e.g. physically) and indirectly (e.g. visually) affect hi storic properties, and information on potential adverse effects to histor ic properties and/or tr aditional cultural prope rties (e.g. ar cheological sites). Historic properties include pl aces, structures, objects, etc. that ar e listed on, or eligible for inclusion on, the National Register of Historic Pla ces. Historic properties include artifacts, records, and remains that are
related to and located within su ch properties.
