1. Overview
In May 2023, the Utah Division of Air Quality (UDAQ) provided notice to Murray City Power Department’s
(Murray City Power’s) Electrical Generation Plant (Murray City Power Plant) detailing potential impacts
that UDAQ anticipated from the reclassification of the Northern Wasatch Front Nonattainment Area for
Ozone from moderate to serious in 2025. With this change in nonattainment classification, sources that
emit or have a potential to emit (PTE) emissions of 50 tons per year (tpy) or more of nitrogen oxide (NOX)
or volatile organic compounds (VOCs) will be considered major stationary sources. As part of UDAQ’s State
Implementation Planning process, UDAQ requested that all stationary sources that would be classified as
major under the 50 tpy threshold prepare and submit a reasonably available control technology (RACT)
analysis. Alternatively, UDAQ gave sources with PTE above the 50 tpy threshold the option of submitting a
Notice of Intent (NOI) that would result in a revised Approval Order that limited the emissions of NOx or
VOC to below 50 tpy.
Murray City Power Plant’s PTE for NOx exceeds the 50 tpy threshold that UDAQ identified for sources to
either submit a RACT analysis or a NOI that reclassified the facility as a minor source. Murray City Power
has elected to prepare and submit a RACT analysis in response to UDAQ’s request. The following is Murray
City Power’s RACT analysis for the Murray City Power Plant.
1.1 Murray City Power Plant Current Operations
Current operations at the Murray City Power Plant are permitted under Approval Order
DAQE-AN103480007-17, issued on May 23, 2017.
PTE emissions in tons per year (tpy) for the Murray City Power Plant are shown in Table 1-1.
Table 1-1. PTE Emissions for Murray City Power Plant
1.2 Reasonably Available Control Technology Analysis
Under the Clean Air Act, UDAQ is required to implement RACT for all major stationary sources as part of
the State Implementation Plan as it responds to reclassification of the Northern Wasatch Front
Nonattainment Area for Ozone. As requested by UDAQ, the RACT analysis should identify and evaluate
reasonable and available control technologies for each relevant pollutant. The technical and economic
feasibility of each potential technology are components of the RACT analysis that help to show whether a
control technology is reasonable. The RACT analysis presented in this document was developed in
accordance with the guidance established by the U.S. Environmental Protection Agency (EPA) and the
Clean Air Act.
A RACT analysis was developed for NOx and VOC emissions. For each emission source, the RACT analysis
followed a four-step process:
Step 1—Identify all control technologies listed in the RACT/BACT/LAER Clearinghouse (RBLC) and/or
California Environmental Protection Agency – Air Resource Board BACT Clearinghouse (CARB).
Step 2—Eliminate technically infeasible options.
Step 3—Eliminate economically/chronologically infeasible options.

2.2 Emission Units
This section describes emission units from the three Solar-Titan gas turbines and the black start generator.
2.2.1 Solar-Titan Gas Turbines
Source Description: The three 11.4 MW Solar-Titan gas turbines generate power to support Murray City’s
electrical generation needs. The turbines are natural-gas fired and are equipped with dry controls
SoLoNOx burners. Emissions of particulate matter less than or equal to 2.5 microns in aerodynamic
diameter (PM2.5), sulfur dioxide (SO2), and VOCs are limited with good design and proper operation.
2.2.1.1 NOx RACT
Step 1—Identify All Control Technologies. The RBLC and CARB databases identify the following as
possible control technologies for NOx for natural gas-fired turbines and duct burners:
- Selective catalytic reduction (SCR)
- Upgrade burners with good combustion practices
- Good design and proper operation

240306125503_6c812a01 2-2
4893-6934-3670.v2
Step 2—Eliminate Technically Infeasible Options. The addition of SCR, as well as good design and
proper operation of the units, constitute technically feasible NOx controls for the existing Solar-Titan
Gas Turbines.
Upgrading or replacing the existing SoLoNOx burners is not technically feasible. Murray City Power
coordinated its RACT analysis of the Solar-Titan Gas Turbines by consulting with vendors with expertise
in making such upgrades. In these discussions, Murray City Power learned that, given the age of the
current equipment, if the existing SoLoNOx burners were to be replaced, Murray City Power would also
be required to upgrade most other components of the Solar-Titan Gas Turbines as the new burners
would not interface or operate correctly with the existing components of the turbines. Consequently,
given the cascading upgrades to other components, which would be equivalent to replacing the entire
system, Murray City has determined that upgrading the burners is not technically feasible.1
Step 3—Eliminate Economically/Chronologically Infeasible Options. The turbine units are equipped
with low-NOx burner (LNB) (SoLoNOx technology burners on turbine) to reduce NOx emissions. The
addition of the SCR will reduce emissions by 64 percent.
Solar Turbines, Inc., provided estimates for add-on SCR controls and other necessary retrofits for each
of the three Titan 130–19501 SoLoNOx combustion turbine units. Based on the annualized costs for
the SCR and the 2017 actual emissions for the emission source, the cost of additional control per ton
of NOx removed was calculated for each turbine unit. This information is presented in Table 2-2. As
shown in the table, the cost of additional control per ton of NOx removed ranges from over 9 million to
nearly 95 million dollars and is therefore not cost effective for RACT. Given the cost-per-ton of NOx
removed, SCR is eliminated as a technically infeasible control.
Step 4—Identify RACT. Existing LNBs with good combustion practices, good design, and proper
operation of the gas turbines constitute RACT.

1 Even if the replacement of the burners were found to be technically feasible, the option to replace the burners would also be
eliminated under step 3 as the replacement of the equipment would be equivalent to the replacement of each existing turbine.

2.2.1.2 VOC RACT
Step 1—Identify All Control Technologies. The RBLC and CARB databases identify the use of
pipeline-quality natural gas and good combustion practices as possible control technologies for small
turbines and duct burners.
Step 2—Eliminate Technically Infeasible Options. Not applicable as all identified control technologies
are technically feasible.
Step 3—Eliminate Economically/Chronologically Infeasible Options. Not applicable because all
potential technologies identified in Step 1 are selected as RACT.
Step 4—Identify RACT. Use of pipeline-quality natural gas and good combustion practices constitute
RACT for this emission source.
LNB with good combustion practices, good design, and proper operation on pipeline-quality natural gas
also represent the most stringent measure for the three gas turbine units.
2.2.2 Black Start Generator
Source Description: Murray City Power operates one 1,000-horsepower (hp), diesel-fired generator that is
to be used for gas turbine startup only during those periods when electric power from public utilities is
interrupted, or for regular generator maintenance. This unit is subject to 40 Code of Federal Regulations
63 Subpart ZZZZ.
Step 1—Identify All Control Technologies. Potential emission control technologies identified in the
RBLC and CARB for similar-sized diesel generators include good combustion practices and limiting the
sulfur content of fuel to 0.0015 percent.
Step 2—Eliminate Technically Infeasible Options. Not applicable as all identified control technologies
are technically feasible.
Step 3—Eliminate Economically/Chronologically Infeasible Options. Not applicable because all
potential technologies identified in Step 1 are selected as RACT.
Step 4—Identify RACT. Good combustion practices, limiting the sulfur content of fuel to 0.0015 percent
and complying with applicable National Emission Standards for Hazardous Air Pollutants (NESHAP)
requirements, are identified as RACT for all pollutants emitted from the emergency generator.
