RE: Daneros Mine Construction Schedule, Approval Order DAQE-GN144920005-20
Project Number N144920005

Dear Mr. Bird:

The Daneros Mine (“Mine”) is permitted under Approval Order (“AO”) DAQE-AN144920002-
14, issued on July 8, 2014 to Energy Fuels Resources (USA) Inc. (“Energy Fuels”) which
transferred ownership to CUR White Canyon Uranium, LLC owned by CUR USA Holding, LLC
(“CUR”) on October 27, 2021. The Mine is located entirely on land owned by the U.S. Bureau of
Land Management (“BLM”) and is operated by Energy Fuels. Energy Fuels continues to act as
the operator of the mine pursuant to an Operating Agreement between the parties and is
submitting the construction status update on behalf of CUR.

Section II.B.1.a Requirements and Limitations of the AO states:
Energy Fuels Resources (USA) Inc. shall notify the Director in writing when the
installation of equipment and preparations for mine operations have been completed and
have become operational. To ensure proper credit when notifying the Director, send your
correspondence to the Director, attn: Compliance Section.
If the installation and preparations have not been completed within 18 months from the
date of this AO, the Director shall be notified in writing on the status. At that time, the
Director shall require documentation of the continuous installation and preparations and
may revoke the AO.
[R307-40 1-18]

As a result of the long timelines associated with mine expansion permitting efforts through the
BLM and its’ impact on the ability to install and operate the equipment permitted under the AO,
extension requests were submitted in 2017, 2018, 2019, and 2021 with the most recent request
dated July 26, 2021. As requested by DAQ, Energy Fuels submitted a revised Best Available
Control Technology (“BACT”) analysis in conjunction with the extension request in February
27, 2019. On April 25, 2022, the DAQ approved the extension and requested that Energy Fuels

303-974-2140
www.energyfuels.com
submit an update on the schedule on or before July 29, 2023. Energy Fuels is herein providing an
update on the project schedule.

The BLM approved the Mine Plan of Operations Modification in February 2018; however, the
BLM’s approval was appealed to the Interior Board of Land Appeals (“IBLA”) and remains
unresolved at this time. Due to circumstances associated with permitting of the mine expansion
through the BLM, CUR requests extension of the installation and preparation schedule for
another one-year period (i.e., until July 29, 2024).

1. INTRODUCTION
The Utah Department of Environmental Quality (UDEQ) Division of Air Quality (DAQ) has requested an
updated Best Available Control Technology (BACT) analysis associated with an extension to commence
construction of the Daneros Mine. This document includes an anticipated construction schedule and an
updated BACT analysis for the Daneros Mine.
2. BEST AVAILABLE CONTROL TECHNOLOGY ANALYSIS
The Daneros Mine is located in the central portion of the Colorado Plateau in western San Juan County,
Utah. The project site is located in Bullseye Canyon, approximately five miles southwest of Fry Canyon.
The project site can be accessed by turning from Highway 95 to Radium King Road and travelling
approximately 14 miles to the site. The surface facilities are located on Federal land administered by the
BLM. The location of the site is within an area that is currently classified as an attainment or unclassifiable
area for air quality.
The Mine will consist of three portal areas, including the Daneros, Bullseye, and South portal areas. The
Daneros and Bullseye portals currently exist but the entrances are closed. An additional decline into the
ore body will be constructed to allow for ore hauling, mine ventilation, and secondary escape routes. Each
portal area will have an ore storage pile, development rock areas (DRAs), diesel generators, diesel storage
tanks, and mobile surface equipment such as front-end loaders, dozers, and haul trucks. The cumulative
surface area disturbance will be approximately 68 acres. Total ore production will be approximately
72,000 tons per year. The total life of the mine is expected to be approximately 20 years.
The mine is located in an area of the state where utility-supplied power and commercially-available
natural gas is unavailable. Therefore, EFRI will generate power using stationary diesel-powered
generators. The mine will have four 455-Kilowatt (kW) diesel-fired generators that will be used for primary
power. EFRI will also operate a 140-kW auxiliary generator used for mine ventilation and emergency
operations.
The permitted mine represents a new minor stationary source and as part of the permitting process is
subject to the State of Utah BACT requirements as defined in Utah Administrative Code (UAC) R307-401.
UAC R307-401 requires the permit applicant to prepare a BACT analysis for every facility, operation, or
process that proposes any activity that would emit an air contaminant into the air.

Daneros Mine Updated BACT
Energy Fuels Resources (USA) Inc., November 2023

Page | 2
UAC R307-401 indicates that the following five criteria should be used when analyzing strategies to
achieve BACT:
1. Energy impacts
2. Environmental impacts
3. Economic impacts
4. Other considerations
5. Cost calculation
A BACT analysis was completed as part of the permitting process and Approval Order (AO) No. DAQE-
AN144920002-14 was issued for the mine on July 8, 2014. The BACT was updated in 2019 because
construction of the mine had not yet been completed. This document updates the 2019 BACT for emission
sources at the Daneros Mine and evaluates any changes in control technologies that may be considered
BACT since the BACT update was approved by DAQ.
The five BACT criteria are discussed, if applicable, for each source type. Three types of emission sources
at the Daneros Mine are discussed in this BACT review, as follows:
1. Material Handling, Storage Pile, and Road Dust Fugitive Emissions
2. Storage Tank Fugitive Emissions
3. Generators
Projected emission amounts from these sources were quantified in emission calculations presented in the
Notice of Intent (NOI) submitted in October 2012.
Updated BACT Review for the Daneros Mine Sources
This analysis reviews the BACT for each of the proposed sources as per the five BACT criteria.
BACT For Material Handling, Storage Pile, and Road Dust Fugitive Emissions
The proposed mine production rate is 72,000 tons per year (tpy) of uranium ore for all portals combined.
The ore will be hauled to the surface using low-profile diesel haul trucks where it will be dumped directly
into ore stockpiles for loading onto haul trucks for transportation to the off-site processing mill. The truck
beds will be covered with tarps to prevent fugitive dust emissions.
The maximum anticipated development rock production rate for the Daneros Mine is 108,000 tpy for all
portals combined. Development rock will be stored at one of the development rock disposal areas (DRA).
The DRAs will be treated with dust suppressants as necessary to minimize fugitive dust emissions and

meet opacity limits. Development rock is a relatively inert material and is not expected to produce a
radiological hazard.
Three topsoil stockpiles will be developed, each located near one of the portals. It is anticipated that
approximately 28,000 tons of topsoil will be stockpiled at the three topsoil stockpiles. Most soil will be
stripped using a tracked dozer, although a front-end loader may also be used. Topsoil stockpiles will be
contoured, furrowed, and broadcast seeded in late fall to establish vegetation. These efforts will continue
until vegetation is established.
Access to the mine is via County Road (CR) B258 (Radium King Road) and CR D0029. CR D0029 will be
restricted during mine operations because it traverses the proposed DRA and ore stockpiles. Secondary
roads, which will have limited vehicle travel, will be used to access vent holes, DRAs, and various surface
facilities. The majority of on-site traffic will occur between the portal areas, DRAs, ore stockpiles, and
surface facilities. Ore haul trucks will travel to the ore stockpiles, and then off-site to the White Mesa Mill
near Blanding, Utah. Airborne particulate matter will be controlled by spraying the regularly travelled site
roads with a calcium chloride solution or equivalent. Surface equipment that will primarily travel on these
roads includes:
• Low-Profile Haul Trucks
• Highway Haul Trucks
• Tanker Truck
• Water Truck
• Motor Grader
• Pick-Up Trucks
Fugitive particulate matter (PM) emissions and inorganic hazardous air pollutants (HAPs) are expected to
result from movement and handling of ore, development rock, and topsoil (collectively referred to as
material handling) and from wind erosion of storage piles of these same materials. UAC R307-205
establishes minimum work practices and emission standards for sources of fugitive emissions and fugitive
dust for sources located in many areas in the state, including the area of the proposed mine. UAC R307-
205-4 states, “Fugitive emissions from sources constructed or modified after April 25, 1971, shall not
exceed 20% opacity.” UAC R307-205-7 also states,
“Any person who owns or operates a mining operation shall minimize fugitive dust as an integral part of
site preparation, mining activities, and reclamation operations. The fugitive dust control measures to be
used may include:
(a) periodic watering of unpaved roads,
(b) chemical stabilization of unpaved roads,

Daneros Mine Updated BACT
Energy Fuels Resources (USA) Inc., November 2023

Page | 4
(c) paving of roads,
(d) prompt removal of coal, rock minerals, soil, and other dust-forming debris from roads and frequent
scraping and compaction of unpaved roads to stabilize the road surface,
(e) restricting the speed of vehicles in and around the mining operation,
(f) revegetating, mulching, or otherwise stabilizing the surface of all areas adjoining roads that are a
source of fugitive dust,
(g) restricting the travel of vehicles on other than established roads,
(h) enclosing, covering, watering, or otherwise treating loaded haul trucks and railroad cars, to
minimize loss of material to wind and spillage,
(i) substitution of conveyor systems for haul trucks and covering of conveyor systems when conveyed
loads are subject to wind erosion,
(j) minimizing the area of disturbed land,
(k) prompt revegetation of regraded lands,
(l) planting of special windbreak vegetation at critical points in the permit area,
(m) control of dust from drilling, using water sprays, hoods, dust collectors or other controls approved
by the director,
(n) restricting the areas to be blasted at any one time,
(o) reducing the period of time between initially disturbing the soil and revegetating or other surface
stabilization,
(p) restricting fugitive dust at spoil and coal transfer and loading points,
(q) control of dust from storage piles through use of enclosures, covers, or stabilization and other
equivalent methods or techniques as approved by the director, or
(r) other techniques as determined necessary by the director.”
Material Handling Fugitive Emissions
Material handling transfer points at the Daneros Mine will include truck loading/unloading, front-end
loader loading/unloading, and ore transfer off-site. Particulate and HAP emissions will be generated as
the material moves through each transfer point. The EPA has developed an emission factor that can be
used to project particulate emissions from a transfer point.1 The emission factor is a function of wind
speed and the material's particle size distribution and moisture content and is multiplied by the material
transfer rate to project emissions. Therefore, potential emissions from a transfer point can be reduced by
decreasing the throughput rate at which the material is transferred, decreasing the wind speed to which
the material is exposed, or increasing the aggregate's moisture content by watering or chemical wetting
agents. HAP emission estimates for each transfer point were based on laboratory reports and are a
function of particulate emissions.

1 AP-42, Section 13.2.4 Aggregate Handling and Storage Piles, January 1995.

Daneros Mine Updated BACT
Energy Fuels Resources (USA) Inc., November 2023

Page | 5
Most of the material being handled on-site (development rock and ore) includes large diameter rock (up
to approximately 6 inches in diameter) rather than finely crushed rock material. Therefore, PM material
handling emissions will be relatively low (less than 1 ton/year). To meet opacity limits, the BACT proposed
for material handling sources at the Daneros Mine includes implementing spray dust suppression systems
as needed and minimizing material drop distances from the buckets of loaders and backhoes/trackhoes.
Ore will be loaded using a front-end loader into 22-ton, over-the-road haul trucks for transportation to
the off-site mill. The proposed BACT for ore emissions during transportation is to cover the truck beds
with tarpaulins to prevent fugitive dust emissions.
Storage Pile Fugitive Emissions
The EPA has developed equations that can be used to project particulate emissions from storage piles.2
Based on these equations, the generation of fugitive dust from a storage pile is a function of threshold
friction velocity (the wind speed necessary to remove dust particles from the storage pile), the material's
size distribution and moisture content, wind speed, and frequency of disturbance. The potential for
fugitive emissions from a storage pile can be reduced by reducing the material's erosion potential,
reducing the wind speed just above the surface of the storage pile, enclosing the pile, and/or reducing the
frequency of storage pile disturbances. Watering or using chemical wetting agents can also reduce the
erosion potential of a storage pile. HAP emission estimates associated with storage piles are a function of
particulate emissions as described above.
Totally enclosing a large material storage pile that is frequently disturbed is not a technically feasible
option to control fugitive emissions and the cost of enclosing the piles would be prohibitive. The
development rock and ore that will be stored on-site will be large diameter rock (up to approximately 6
inches in diameter). Therefore, storage pile PM emissions from these materials will be low.
To reduce emissions from the topsoil storage piles, the proposed BACT is to seed the topsoil storage piles
with a temporary fast-growing seed mix to stabilize the soil. It is estimated that seeding the topsoil piles
will reduce fugitive dust emissions by at least 90%.
Road Dust Fugitive Emissions
Particulate emissions will be generated by trucks and other vehicle traffic. The force of the wheels on the
road surface causes pulverization of surface material when a vehicle travels an unpaved road. Particles
are lifted and dropped from the rolling wheels, and the road surface is exposed to strong air currents in
turbulent shear with the surface.

2 AP-42, Section 13.2.5 Industrial Wind Erosion, January 1995.

Daneros Mine Updated BACT
Energy Fuels Resources (USA) Inc., November 2023

Page | 6
Particulate emissions associated with vehicle traffic can be reduced by paving the road, limiting vehicle
speeds, or using control techniques such as water sprays to minimize dust formation. Potentially feasible
control options for the Daneros Mine include wet suppression with water and/or chemical agents and
limiting vehicle speeds.
Paving the haul roads would be economically infeasible and would not result in good control of particulate
emissions because of material covering the pavement and becoming airborne. Use of gravel is also costly
and not effective because the heavy truck traffic disperses the gravel and exposes the unpaved roadway.
Therefore, the proposed BACT for fugitive dust from the Daneros Mine roads is to limit vehicle speeds to
15 miles per hour on mine site roads. In addition, magnesium chloride or calcium chloride will be sprayed
on the haul roads within the mine workings, development rock area, and portal area as needed to reduce
fugitive dust. A water truck will also be used to spray regularly traveled mine roads. It is estimated that
treating the roads and enforcing speed limits will reduce fugitive dust emissions by at least 75%.
BACT for Fuel and Oil Storage Areas
Diesel fuel and other petroleum products will be stored on-site in above-ground storage tanks, drums,
and smaller containers. Four, 6,000 gallon diesel fuel storage tanks will be used at the Daneros Mine. Two
tanks will be located at the Daneros Portal area, one at the Bullseye Portal area (temporarily), and
ultimately two at the South Portal area.
Small amounts (likely less than 500 gallons) of antifreeze and oil products (i.e., motor oil, hydraulic oil,
gear oil, and used oil) will be stored at the maintenance shops on the shop floors and used-oil storage will
be in 55-gallon drums. These products will typically be stored in smaller tanks of less than 100 gallons,
drums, and small containers. Due to the low volatility of these materials, air emissions from the antifreeze
and oil products are insignificant and have not been included in the emissions inventory.
Small amounts of VOC fugitive emissions will likely result from the on-site storage of petroleum-based
fuels. The tanks that are associated with the generators will be steel tanks coated in a light-colored paint
to minimize fugitive emissions. Further controls are not warranted with tanks of this size.
BACT for Generators
EFRI will generate power using stationary diesel-powered generators. The mine will have four 455-kW
diesel-fired generators that will be used for primary power. The proposed generator engines will be
Caterpillar C15 (or C18) ATAAC diesel engines. Two of the generators will be co-located at the Daneros
Portal area, one at the South Portal area, and the fourth 455-kW generator will be located at the Bullseye
Portal area and later moved to the South Portal. EFRI will also operate a Whisperwatt auxiliary generator
used for mine ventilation and emergency operations. The generator will be powered by a Cummins QSB7-
G7 140-kW diesel engine.

Daneros Mine Updated BACT
Energy Fuels Resources (USA) Inc., November 2023

Page | 7
The four proposed 455-kW generators will comply with U.S. Environmental Protection Agency (EPA)
emission standards as defined in the Code of Federal Regulations (CFR) 40 CFR 60, Subpart IIII (Standards
of Performance for Stationary Compression Ignition Internal Combustion Engines). The generators are
certified Tier 4 engines. According to the Caterpillar Exhaust Emission Data Sheet for Model C15 ATAAC
(see Attachment 1), the generator emissions in grams per horsepower-hour (g/hp-hr) for 100 percent load
are: 2.6 g/hp-hr nitrogen oxides (NOx); 2.6 g/hp-hr carbon monoxide (CO); 0.075 g/hp-hr PM; and 0.298
g/hp-hr total unburned hydrocarbons (HC). The EPA has developed emission factors that can be used to
project uncontrolled emissions from diesel generators greater than 600 horsepower (hp).3 Per AP-42,
emission factors for uncontrolled diesel generators (i.e. not EPA Tier compliant) are: 10.89 g/hp-hr NOx;
2.49 g/hp-hr CO; 0.32 g/hp-hr PM; and 0.32 g/hp-hr HC.
The proposed 140-kW standby generator will also comply with EPA Tier 4 emission standards. The Tier 4
standards are given in 40 CFR 1039. For generators rated at 130 kW to 560 kW, air emissions are limited
to 0.30 g/hp-hr NOx; 2.6 g/hp-hr CO; 0.015 g/hp-hr PM; and 0.14 g/hp-hr HC. For comparison, EPA
emission factors for uncontrolled diesel engines4 up to 600 hp are: 14.06 g/hp-hr NOx; 3.03 g/hp-hr CO;
1.00 g/hp-hr 10-micron PM (PM10); and 1.12 g/hp-hr HC. This generator will also be limited to 1,000 hours
operation per year.
A top-down BACT analysis was conducted for the generators. The steps to determine BACT for each
pollutant are listed below:
Step 1: Identify Potentially Available Control Technologies
Step 2: Eliminate Technically Infeasible Options
Step 3: Rank Technologies by Control Effectiveness
Step 4: Evaluate Most Effective Controls
Step 5: Select BACT
Potential emission control technologies for non-emergency diesel engines less than 2,000 kW were
summarized from the RACT/BACT/LAER Clearinghouse (RBLC). The search results for diesel-fired engines
are summarized in Table 1. The RBLC listing is provided in Attachment 2.
BACT for NOx
Step 1 - Identification of NOx Control Technologies
The RBLC data indicate that good combustion/operation/maintenance practices, certification with the
federal emission standards for compression ignition engines, and turbocharger/aftercooler/high injection
pressure are the primary NOx control technologies for diesel engines.

3 AP-42, Section 3.4 Large Stationary Diesel and All Stationary Dual-Fuel Engines, Table 3.4-1, October 1996.
4 AP-42, Section 3.3 Gasoline and Diesel Industrial Engines, Table 3.3-1, October 1996.

Table 1: RBLC Search Results - Non-Emergency Diesel-Fired Engines <2000 kW
Control Number of Determinations Pollutants Controlled
Good Combustion / Operation / and
Maintenance Practices 16 All
NSPS-Certified 13 All
Turbocharger/aftercooler/High
Injection Pressure 3 NOx, CO, VOC, PM
Clean Fuel 5 PM, SO2, H2SO4

A turbocharger compresses air as it is injected into the engine cylinders and thereby increases power
output. An aftercooler is used with a turbocharger to reduce intake air temperature which increases due
to compression by the turbocharger. The reduced intake air temperature helps reduce NOx formation.
High injection pressure is also related and optimizes the combustion process.
The New Source Performance Standards (NSPS) for stationary compression ignition internal combustion
engines are defined in 40 CFR Part 60, Subpart iiii. Pollutant emission limits in this regulation apply to
diesel engines manufactured after April 1, 2006 or modified/reconstructed after July 11, 2005.
Step 2 - Eliminate Technically Infeasible NOx Control Technologies
The NSPS emission requirements apply to both the Caterpillar C15/C18 ATAAC generator engines and the
Cummins QSB7-G7 generator engine. Use of good combustion/operation/maintenance practices,
turbocharger/aftercooler/injection pressure technologies and certification with federal emission
standards are considered technically feasible.
Step 3 - Rank the Remaining NOx Control Technologies
The remaining control technologies are ranked based on the estimated efficiency for the control of NOx
emissions from the engines.
(1) NSPS-Certified (76-98% control compared to AP-42 emission factors)
(2) Good combustion/operation/maintenance practices (<40% control)
(3) Turbocharger/Aftercooler/Injection Pressure (6-10% control)

Step 4 – Evaluation of the Most Effective Controls
The Caterpillar engines and the Cummins engine will be NSPS Tier 4 certified engines. An NSPS-certified
engine is the most effective method from the RBLC search for reducing NOx emissions. Maintaining good
combustion practices by following the manufacturer’s operation and maintenance procedures at all times
of operation will result in optimum combustion and also reduce air emissions.
Energy Impacts – No significant energy impacts were identified in the evaluation. Use of Tier 4 diesel
generators would result in similar diesel usage as with uncontrolled engine.

Daneros Mine Updated BACT

Environmental Impacts – No significant differences in environmental impacts were identified between
the BACT options.
Economic Impacts - An economic impact analysis was completed to evaluate the comparative cost of a
new Tier 4 generator, a used Tier 4 generator, and a generator not subject to NSPS emission limitations.
The cost considerations with controlling NOx emissions include the dollars per ton of pollutant removed
and the total tons of pollutant removed. The value of the proposed generators was established based on
a cost quotation for a new CAT C18 generator and a search of similar used generators currently available
for sale. The value of the non-NSPS generators was established based on a search of generators
currently available for sale. The searches took into consideration the size, model, and model year of the
generators.
Costs associated with the generators are provided in Table 2. The cost data were calculated following
UDEQ BACT guidance. The following equations were used in these calculations.
A = (B + C) / D
Where:
A = Annualized cost expressed in dollars per ton
B = Annualized equipment cost in $/yr = PV{i/(1-(1+i)-n}
Where:
PV = Present day value of the equipment
I = Interest rate at which the company can borrow money = 10% (assumed)
N = Number of years of the life of the equipment = 10 years assumed for the existing
generator and 20 years assumed for the new Tier 4 generator
C = Annual operating cost
D = Amount of emission reduction due to the installation and operation of a Tier 4 generator

Step 5 - Proposed NOx BACT
The estimated annualized cost per ton to reduce NOx emissions is $624/ton for installing a new Tier 4
primary generator, $262/ton for installing a used Tier 4 primary generator, and $1,542/ton for installing
a Tier 4 auxiliary generator. These are considered reasonable annualized costs. Therefore, the proposed
BACT for NOx includes the control technologies/procedures listed below:
Caterpillar C15/C18 ATAAC and Cummins QSB7-G7 Engines:
(1) NSPS-Certified Tier 4 engines
(2) Good combustion/operation/maintenance practices

Use of ultra-low sulfur diesel (ULSD) fuel will reduce formation of SO2 as well as sulfate (SO4) PM. Because
ULSD is the only diesel fuel available, its use is assumed and therefore is not specifically listed in the BACT
analysis. Other listed control technologies were discussed under the NOx BACT section.

Step 2 - Eliminate Technically Infeasible PM Control Technologies
None
Step 3 - Rank the Remaining PM Control Technologies
The remaining control technologies are ranked based on the estimated efficiency for the control of PM
emissions from the engines.
(1) NSPS-Certified (76-98% control compared to AP-42 emission factors)
(2) Good combustion/operation/maintenance practices (<40% control)

Step 4 – Evaluation of the Most Effective Controls
The diesel-fired engines will be NSPS-certified as described in the BACT for NOx. Use of an NSPS-certified
engine is the most effective method from the RBLC search for reducing PM emissions. Maintaining good
combustion practices by following the manufacturer’s operation and maintenance procedures at all times
of operation will result in optimum combustion and thereby reduce air emissions.

Step 5 - Proposed PM BACT
The proposed BACT for PM includes the two control technologies/procedures listed below:
(1) NSPS-Certified
(2) Good combustion/operation/maintenance practices

BACT for SO2
Step 1 - Identification of SO2 Control Technologies
The RBLC data indicate that good combustion/operation/maintenance practices and use of ULSD are the
primary SO2 control technologies for the diesel engines. Use of ULSD could reduce SO2 emissions up to 99
percent compared to diesel with sulfur content of 0.5 percent. However, as stated in the PM BACT, use of
ULSD is assumed and not considered part of the BACT.
Step 2 - Eliminate Technically Infeasible SO2 Control Technologies
None.
Step 3 - Rank the Remaining SO2 Control Technologies
The remaining control technologies are ranked based on the estimated efficiency for the control of SO2
emissions from the engines.
(1) Good combustion/operation/maintenance practices (<40% control)

Step 4 – Evaluation of the Most Effective Controls
Maintaining good combustion practices by following the manufacturer’s operation and maintenance
procedures at all times of operation will result in optimum combustion and thereby reduce air emissions.
Step 5 - Proposed SO2 BACT
The proposed BACT for SO2 includes the control technologies/procedures listed below:
(1) Good combustion/operation/maintenance practices

BACT for CO, VOC, CO2
Step 1 - Identification of CO, VOC, and CO2 Control Technologies
The RBLC data indicate that good combustion/operation/maintenance practices, certification with the
NSPS emission standards for compression ignition engines, and turbocharger/aftercooler/high injection
pressure are the primary CO, VOC, and CO2 control technologies for diesel engines.

Daneros Mine Updated BACT
Energy Fuels Resources (USA) Inc., November 2023

Page | 12
Step 2 - Eliminate Technically Infeasible CO, VOC, and CO2 Control Technologies
None
Step 3 - Rank the Remaining CO, VOC, and CO2 Control Technologies
The remaining control technologies are ranked based on the estimated efficiency for the control of CO,
VOC, and CO2 emissions from the engines.
(1) NSPS-Certified (0-88% control compared to AP-42 emission factors)
(2) Good combustion/operation/maintenance practices (<40% control)
(3) Turbocharger/Aftercooler (6-10% control)

Step 4 – Evaluation of the Most Effective Controls
Use of an NSPS-certified engine is the most effective method from the RBLC search for reducing VOC and
CO2 emissions. Based on a comparison with uncontrolled AP-42 emission factors, CO emissions would
either not decrease or decrease only a small amount. However, the reductions of other criteria pollutants
associated with NSPS-certified engines is significant. Maintaining good combustion practices by following
the manufacturer’s operation and maintenance procedures at all times of operation will result in optimum
combustion and thereby reduce air emissions.
Step 5 - Proposed CO, VOC, and CO2 BACT
The proposed BACT for CO, VOC, and CO2 includes the following control technologies/procedures listed
below:
(1) NSPS-Certified
(2) Good combustion/operation/maintenance practices

Conclusions
The proposed BACT for emission sources at the Daneros Mine are summarized in Table 3. No significant
waste products are expected to be associated with the proposed diesel engines.

Permit Notes:The proposed new plant will be replacing the electrical generating capacity of both BWL’s existing coal-fired power plants. BWL
intends to retire those coal-fired power plants from service by 2025. However, before they can be retired, the new natural gas power
plant must be operational. Emissions in the area will increase for a short period if the new combined-cycle plant is built. However,
there will be overall reductions in emissions when the existing coal fired power plants are taken out of service.
