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 Executive Secretary, Utah Air Quality Board:
Company Name: Questar Pipeline Company
Location: Questar Pipeline Company: Blind Canyon Compressor station Remote Location, West Tavaputs Plateau, Myton, UT, Duchesne County
Project Description: Questar Pipeline Company (Questar) has requested a modification to Approval Order DAQE-AN0130790003-07, to replace one existing turbine compressor with a new turbine engine at the Blind Canyon Compressor Station. The new engine has a larger capacity than the existing compressor engine. The potential to emit emissions will change as follows: +0.17 tons per year (TPY) of PM10, +0.17 TPY of PM2.5, -5.29 TPY of NOx, +0.08 TPY of SOx, and 3.0 TPY of CO, -65.29 TPY of VOCs, -2.43 TPY of combined HAPs and +2,955.64 TPY of CO2e. Total potential to emit emissions for the Blind Canyon Compressor Station are 2.47 TPY of PM10, 2.47 TPY of PM2.5, 39.84 TPY of NOx, 1.19 TPY of SOx, and 47.40 TPY of CO, 32.82 TPY of VOCs, 1.62 TPY of combined HAPs and 52,143.63 TPY of CO2e.
The Questar Blind Canyon Compressor Station is subject to New Source Performance Standards, Subpart KKKK, Standards of Performance for Stationary Combustion Turbines. The Blind Canyon Compressor station is not subject to any National Emission Standards for Hazardous Air Pollutants. Questar Blind Canyon Compressor Station is classified as a minor source of air pollution and is not subject to the Operating Permit Program. Questar Blind Canyon Compressor Station is located in Duchesne County which is an attainment area for all criteria pollutants. This source is a minor source for greenhouse gases. This project requires a 30-day public comment due to the increased 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 Executive Secretary 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 March 22, 2012 will be considered in making the final decision on the approval/disapproval of the proposed project.
