A Notice of Intent for the following project submitted in accordance with R307-401-1, Utah Administrative Code (UAC), has been received for consideration by the Director:
Company Name: EP Energy E&P Company, L.P.
Location: Monsen 1-21A3 Production Tank Battery SE-NE S21 T1S R3W, Duchesne County, UT
Project Description: EP Energy E&P Company LP (EP Energy) has requested a modification to Approval Order DAQE-AN2683001-02 dated September 9, 2002, to increase the crude oil throughput, add existing equipment, and install new equipment for the Monsen 1-21A3 tank battery. As part of this modification, EP Energy has requested to update the permitted crude oil storage tanks and to install a new combustor and a new generator engine. This facility will process up to 255,500 barrels of crude oil per year.
The source is located in Duchesne County, which is an unclassified area of the National Ambient Air Quality Standards for ozone and an attainment area for all other pollutants. New Source Performance Standard (40 CFR 60 Subparts A, JJJJ, and OOOO) and Maximum Achievable Control Technology (40 CFR 63 Subparts A and ZZZZ) regulations apply to this source. National Emission Standards for Hazardous Air Pollutants (40 CFR 61) regulations and Title V of the 1990 Clean Air Act do not apply to this source.
The potential emissions, in tons per year, will change as follows: PM10 = + 0.42, PM2.5 (subset of PM10) = + 0.42, NOx = + 3.32, CO = + 18.92, SO2 = + 0.03, VOC = + 1.43, HAPs = + 2.24, and CO2e = + 10,170.
The potential emissions, in tons per year, will be as follows: PM10 = 0.42, PM2.5 (subset of PM10) = 0.42, NOx = 9.38, CO = 19.78, SO2 = 0.03, VOC = 18.04, HAPs = 2.24, and CO2e = 10,170. PM10, PM2.5, SO2, HAPs, and CO2e emissions were not accounted for in the previous permit. The Utah Division of Air Quality has treated the unaccounted for emissions as new emissions.
The completed engineering evaluation and air quality impact analysis showed that the proposed project meets the requirements of federal air quality regulations and the State air quality rules. The Director intends to issue an Approval Order pending a 30-day public comment period. The project proposal, estimate of the effect on local air quality and draft Approval Order are available for public inspection and comment at the Utah Division of Air Quality, 195 North 1950 West, Salt Lake City, UT 84116. Written comments received by the Division at this same address on or before May 18, 2017 will be considered in making the final decision on the approval/disapproval of the proposed project. Email comments will also be accepted at If anyone so requests to the Director in writing within 15 days of publication of this notice, a hearing will be held in accordance with R307-401-7, UAC.
Under Section 19-1-301.5, a person who wishes to challenge a Permit Order may only raise an issue or argument during an adjudicatory proceeding that was raised during the public comment period and was supported with sufficient information or documentation to enable the Director to fully consider the substance and significance of the issue.
