Public Notice

 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: Bill Barrett Corporation

Location: Bill Barrett Corporation: Sage Brush Flat Compressor Station
- Remote location, Carbon County, Junction of Nine Mile Canyon and
Cottonwood Canyon, Carbon City, UT, Carbon County

Project Description: Bill Barrett Corporation (BBC) has requested to
modify DAQE-AN2929002-06 to install one additional compressor engine,
two generator engines, two additional condensate storage tanks and
increase dehydrator capacities at the Sage Brush Flats Compressor
Station.  The Sage Brush Flats Compressor Station is located north
east of Price, Utah.  BBC's Sage Brush Flats Compressor Station is
classified as major source for NOx, VOC and CO, and requires a Title V
permit when constructed.  Modeling was conducted for benzene,
formaldehyde, acrolein, CO, PM2.5, PM10 and NOx.  Modeling showed that
all pollutants modeled meet National Ambient Air Quality Standards
(NAAQS) and Toxic Screening Level.  The emission estimates from this
modification are as follows:  1.27 Tons Per Year (TPY) of PM10/PM2.5,
7.52 TPY of NOx, 30.83 of TPY CO, 37.27 TPY of VOC, 0.51 TPY of SOx,
and 11.43 TPY of combined HAPs.  The potential emissions from the Sage
Brush Flats Compressor Station are as follows:  9.39 TPY of
PM10/PM2.5, 146.53 TPY of NOx, 151.46 of TPY CO, 121.41 TPY of VOC,
0.51 TPY of SOx and 19.83 TPY of combined HAPs.

 The Sage Brush Flats Compressor Station is located in an attainment
area for all criteria pollutants.  This site is subject to New Source
Performance Standard (NSPS) Subpart JJJJ, and area source National
Emission Standards for Hazardous Air Pollutants (NESHAP) Subpart ZZZZ.
 This source is classified as a major source due to the emissions of
146.53 TPY of NOx, 151.46 TPY of CO and 121.41 TPY of VOC.  Title V
does apply to this source.  Since there will be an increase in
emissions associated with this proposal, a 30-day public comment
period is required.

 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 April 7, 2011 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 Executive Secretary
at the Division in writing within 15 days of publication of this
notice, a hearing will be held in accordance with R307-401-7, UAC.
