 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: Nielson Construction Company
Location: Nielson Construction Company: Mill Flat Asphalt and 
  Aggregate Pit - About 2 miles North and West, of 
  Huntington on Hwy 31, Emery County, UT 

 Project Description: Nielson Construction Company has requested a
modification to Approval Order (AO) DAQE-AN2894002-04 dated August 9,
2004, to replace an old asphalt plant and baghouse with a newer,
larger asphalt plant and baghouse.  The old asphalt plant was rated at
350 tons per hour, and the new asphalt plant is rated at 400 tons per
hour.  The facility layout has changed, and emission factors have been
updated since the issuance of the previous AO.  Aggregate production
will also be decreased at the facility.  A dispersion modeling
analysis was performed for PM10, NO2, formaldehyde, chromium, and
nickel.  The modeling results, showing that the predicted total
concentrations are less than the respective (National Ambient Air
Quality Standards) NAAQS or Toxic Screening Level (TSL), are contained
in DAQE-MN0128940007-11 dated March 23, 2011.

 Emery County is an attainment area of the NAAQS for all pollutants. 
New Source Performance Standards (NSPS) 40 CFR 60 Subpart A, Subpart
I, Subpart OOO, Maximum Achievable Control Technology (MACT) 40 CFR 63
Subpart A, and Subpart ZZZZ regulations apply to this source. 
National Emission Standards for Hazardous Air Pollutants (NESHAP) 40
CFR 61 regulations do not apply to this source.  Title V of the 1990
Clean Air Act applies to this source, and this source is considered a
Title V area source.

 The potential emissions, in tons per year, will change as follows:
PM10 + 11.84 (which includes PM2.5), PM2.5 + 11.11 (not previously
accounted for), NOx - 4.68, SO2 - 0.88, CO - 0.80, VOC + 5.00, HAPs +

 The changes in emissions will result in the following, in tons per
year, controlled potential to emit totals: PM10 = 25.76 (which
includes PM2.5), PM2.5 = 11.11, NOx = 26.46, SO2 = 21.12, CO = 49.72,
VOC = 17.68, HAPs = 3.99, CO2e = 12,104.

 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 AO pending a 30-day public comment
period.  The project proposal, estimate of the effect on local air
quality and draft AO 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 26, 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.
