Re: URI Kingsville Uranium Precipitate Product
Dear Mr. Howard:
Div of Waste Management and Radiation Control
MAY - 6 2020
Please be advised that Energy Fuels Resources (USA) Inc. ("EFRI") intends to receive uranium precipitate
product ("Uranium Precipitate"), an intermediate form of yellowcake from Uranium Resources Inc.' s ("URI's")
Kingsville Dome, Texas uranium in-situ recovery ("ISR") facility (the "Site"), at the White Mesa Mill (the
"Mill"), as a "licensee-to-licensee" transfer of source material under 10 CFR 40.51(5). The Mill will then
concentrate and purify the Uranium Precipitate for the recovery of commercially salable yellowcake as a
continuation of the milling process begun at the URI facility. As the Uranium Precipitate is currently classified
as 11 e.(2) byproduct material from an ISR facility, the Mill is licensed to receive the Uranium Precipitate under
Condition 10.5 of the Mill' s Radioactive Materials License (the "Mill License") as 1 le.(2) byproduct for direct
disposal in the Mill's tailings system. However, because the Uranium Precipitate is an intermediate form of
yellowcake, with significant recoverable uranium value, EFRI intends to process the material for the purification
and concentration of the contained uranium rather than dispose of it directly.
Historic URI and EFRI Management of the Uranium Precipitate
URI' s ISR process extracts uranium solutions directly from the sandstone formation which hosts the uranium ore
body, without excavation and digestion of the host ore rock. This part of the ISR process performs the same
function for in-situ sandstone ores as the leach, CCD, and clarification steps of the Mill perform for excavated
hard rock ores. At the Site, the extracted uranium solutions are processed for recovery of the uranium values in
the central processing plant in which the subsequent sequence of steps or circuits is comparable, or in some cases
identical, to the concentration, precipitation, and drying steps of a conventional uranium mill. Materials removed
from the backwashing and flushing of filters, resin beds, and process lines in the ISR plant are similar to materials
removed from these types of equipment in the Mill. In the Mill, solids and slurries generated from backwashing
and flushing of equipment can be returned to any number of points in the circuit, such as acid or alkaline re-
digestion, counter-current decantation ("CCD"), or clarification steps, for additional removal of metal impurities
and recovery of the contained uranium values. However, unlike the Mill, ISR facilities do not operate acid or
alkaline digestion circuits or CCD circuits. Hence, when ISR facilities like the Site withdraw and collect uranium-
bearing solids that require re-digestion, or re-purification to remove metal impurities, they cannot sufficiently re-
condition the withdrawn product.

Over the past 27 years of operation, such solids accumulated at the Site in the filtration, ion exchange, and
membrane equipment from backwashing and rinsing. This material contained recoverable uranium, as well as
elevated levels of iron and impurities, remaining from the ore source. Due to its uranium content, the material
recovered froth the backwashing of the filtration and concentration operations (the "Pond Material") was
segregated from other streams and stored in two on-site ponds (the north and south ponds). Since the Pond
M4teria1 contained a significant amount of uranium, URI made extensive efforts to isolate the Pond Material for
the potential future continuation of the milling process and conversion of the Pond Material into a commercially
salable uranium product.
From 2008-2013, URI shipped a portion of the Pond Material to the Mill for direct disposal in the Mill's tailings
system as 1 le.(2) byproduct Material.
In 2013, URI attempted to continue the milling process and conversion of a portion of the Pond Material into a
commercially salable uranium product, and produced approximately 38,000 pounds of Uranium Precipitate,
which is a sodium diuranate wet yellowcake material. URI used the same type of alkaline precipitation with
sodium ions to produce the Uranium Precipitate, as the alkaline precipitation with ammonium ions conducted at
the Mill to produce the Mill' s ammonium diuranate wet yellowcake, which is fed to the Mill's dryers. However,
the alkaline precipitation which recovered the Uranium Precipitate from the Pond Material precipitated not only
the uranium, but the iron as well. As a result, the Uranium Precipitate, or sodium diuranate wet yellowcake,
contains iron at levels in excess of commercially acceptable yellowcake product. Because the Site does not
contain circuits capable of removing the iron from the Uranium Precipitate, URI has been unable to condition the
Uranium Precipitate to meet commercial limits for iron content.
The Mill, with its existing process equipment, is able to remove iron before the uranium is re-concentrated in the
Mill's precipitation circuit, in the same way the Mill re-processes its own off-spec product to remove excess metal
impurities, as discussed below. In other words, the Uranium Precipitate is the same type of intermediate
yellowcake product the Mill deals with on a routine basis when it re-processes its own off-spec product to remove
excess metal impurities. The Mill is able to take this intermediate product and run it through its existing circuits
to continue the milling process by concentrating and purifying this intermediate Uranium Precipitate product into
commercially salable yellowcake.
Proposed Reprocessing of the Uranium Precipitate
Under the proposed transaction, URI will transfer the Uranium Precipitate to the Mill under 10 CFR 40.51 and
the Mill will receive the Uranium Precipitate under the existing Mill License, as a "licensee-to-licensee" transfer
of source material.
The Uranium Precipitate will be shipped to the Mill in the same type of Supersaks®, and in the same type of
transport vehicles as has been used to date for the direct disposal of 1 le.(2) byproduct material from the Site. The
Uranium Precipitate will then be removed from the Supersaks® and introduced into one of the Mill's existing
circuits, to be concentrated and purified into a yellowcake product that meets commercial specifications for
introduction into a conversion facility. As discussed above, the Uranium Precipitate consists of an intermediate
uranium product, a form of yellowcakel, which requires removal of iron impurities, dewatering, and drying, to
Uranium milling produces a number of different uranium oxide products any of which, or combinations of which,
comprise wet or dry "yellowcake". Depending on the precipitation agent, and/or the extent of drying, yellowcake products
may be in the chemical form of sodium diuranate, ammonium diuranate, uranium dioxide, uranium trioxide, and triuranium
octoxide, or others. (Hausen 1998, Kent and Riegel 2007)

meet the ASTM standards for commercial yellowcake product. The Uranium Precipitate may be ground in the
SAG mill and fed to the leach circuit, fed directly to the CCD circuit, or fed to the alternate feed circuit to reenter
the main Mill at the SX circuit. Solution leaving the CCD circuit or alternate feed circuit will be clarified and
thickened, fed to the SX circuit, and will proceed through the remainder of the Mill process in the same manner
as solutions leached from ores and other feeds. The Mill's processing of the Uranium Precipitate will result in a
concentrated and purified form of yellowcake that meets all of the commercial specifications for yellowcake.
The resulting tailings, including the emptied Supersaks®, will be disposed of in the Mill's tailings cells as 1 le.(2)
byproduct material. The steps and processes involved in putting the material into solution, and precipitating,
drying and packaging the yellowcake, will be no different from the steps that would be taken by the Mill to
recirculate and recondition any other off-spec product generated at the Mill. The process of emptying the
Supersaks®, will be no different from the process of introducing into the Mill any other feed delivered in
Supersaks®.
Our ongoing discussions with URI confirm that neither the Pond Material nor the Uranium Precipitate has been
combined with, nor contains, any other materials or constituents. Indeed, since URI viewed the Pond Material as
recoverable product, throughout the life cycle of the material they have taken steps to ensure that it was not
contaminated with any other plant materials, so it could potentially be processed into commercially salable
uranium oxide product at a later date. The details provided below confirm that the Pond Material and Uranium
Precipitate has not been commingled with any other material or constituents.
URI proposes to ship approximately 38,000 wet pounds of Uranium Precipitate (approximately 60% moisture,
40% solids) containing approximately 2,000 dry pounds of U308.2 Based on the information below, EFRI
believes that the Uranium Precipitate can be concentrated and purified into commercially salable yellowcake in
the Mill's existing process circuits. The Supersaks® would then be disposed of in the Mill' s tailings cells in the
same manner as Supersaks® currently received with 1 1 e.(2) byproduct materials.
EFRI believes it is preferable to remove the uranium content from the Uranium Precipitate prior to disposal in
the Mill' s tailings impoundments because this additional step will:
1. reduce the total radioactivity contributed to the tailings by removal of the uranium activity; and
2. recover an economically valuable uranium resource.
Because URI is unable to concentrate and purify the Uranium Precipitate into commercially salable yellowcake
product at the Site, it has agreed that all of the concentrated and purified yellowcake from the Uranium Precipitate
will be for the sole account of EFRI. In consideration, EFRI has agreed to receive the Uranium Precipitate, which
would otherwise need to be disposed of directly as 1 le(2) byproduct material at the Mill if not concentrated and
purified into commercially salable yellowcake product, without the need for URI to pay the normal 1 le.(2)
byproduct material disposal fee for that volume of material.
2 While these are our best estimates of quantities at this time, it would not be unreasonable to expect that these quantities could increase by up to 50%. Therefore, for purposes of this letter, we assume that the quantities are up to approximately
57,000 wet pounds of Uranium Precipitate and approximately 3,000 dry pounds of contained U308.

Characterization Data
URI performed sampling and characterization of the Pond Material and Uranium Precipitate over a period of
several years as indicated in the summary below:
Sampling Date Number of Samples Analyses
April 2012 1 TCLP metals; TCLP Base-Neutral
Extractables (SVOCs); radionuclides. This
is a sample of the Pond Material.
May 2013 1 TCLP metals; TCLP Base-Neutral
Extractables (SVOCs). This is a sample of
the Uranium Precipitate
April 2014 2 TCLP Base-Neutral Extractables (SVOCs).
This is a sample of the Uranium Precipitate.
April 2015 2 Total Metals; Total VOCs; Total SVOCs.
This is a sample of the Uranium Precipitate.
The data, which resulted from multiple samples collected over a four-year period, are sufficiently representative
of the composition of the Pond Material and the Uranium Precipitate. Laboratory Reports for the above sampling
events are provided in Attachment 1. Data from the analyses are discussed below.
The data demonstrate that the Uranium Precipitate product contains elevated levels of impurities that make it
inconsistent with the ASTM standard for acceptable ranges of impurities in commercial yellowcake product. The
Table in Attachment 1 compares each of the analytical results for total metals from the 2015 sampling to the
ASTM C967-08 Standard Specification for Uranium Ore Concentrate.
The data also indicate that the Uranium Precipitate:
• consists of natural uranium concentrates (yellowcake);
• contains no volatile organic (VOC) or semi-volatile organic constituents (SVOCs);
• contains no constituents other than those associated with recovery of natural uranium from the host ore
body; and
• does not exhibit the RCRA toxicity characteristic (its constituents are not leachable by the RCRA test
methods).
The data also demonstrate the consistency and stability over time of the Pond Material and resulting Uranium
Precipitate. As would be expected in an ISR plant setting, the data confirm that over the four-year period during
which the various test samples were collected, no hazardous organic constituents or organic wastes of any type
were added to the Pond Material or Uranium Precipitate. The components of the Uranium Precipitate which are
not specified in Table 1 or the analytical data reports are sediments (muds and sands) from the URI uranium
purification process which were entrained in the Pond Material when it was first transferred to the ponds.

Regulatory Considerations
EFRI has considered the following in making its determination and conclusions.
Transport
USDOT regulations and existing procedures already regulate the shipment of 1 le.(2) byproduct material between
the Site and the Mill. Pond Material has already been shipped to the Mill from the Site for direct disposal as
1 le.(2) byproduct material, and if not further concentrated and purified at the Mill, the Uranium Precipitate would
be disposed of directly at the Mill as I le.(2) byproduct material. The number of trucks associated with
transporting the Uranium Precipitate to the Mill will be the same whether the material is transported to the Mill
for direct disposal as 1 le.(2) byproduct material or for concentration and purification into commercially salable
yellowcake product.
Receipt
The first paragraph and Conditions 6, 7, and 8 of the Mill License allow EFRI to "transfer, receive, possess and
use" "natural uranium" "in any form" with "no maximum quantity limit". Receipt of the Uranium Precipitate
Material would be a licensee-to-licensee transfer of source material to the Mill under 10 CFR 40.5 1(5), because
the Mill is "authorized to receive such source or byproduct material" under the terms of the Mill License, which
is "a specific license or a general license or their equivalents issued by the Commission or an Agreement State,"
as required by that regulation.
Composition of the Transferred Source Material
As discussed above, the Uranium Precipitate consists solely of precipitated uranium product from the Site's
uranium filtration and uranium concentration area cleanout steps. Neither the Uranium Precipitate nor the
Supersaks® contain any constituent that is not present and handled routinely at the Mill. The Uranium Precipitate
is a further refined version of the Pond Material that has previously been shipped to the Mill for direct disposal
in the Mill's tailings system as 1 le.(2) byproduct material.
The detailed analysis of the Uranium Precipitate is discussed above. The,Supersaks® to be used for shipment are
the same type of conveyance received at the Mill and disposed of in the tailings system on a regular basis from
other feed materials. In fact, as discussed above, the Pond Material prior to precipitation, and the Supersaks® in
which it was transported, have been disposed of directly in the Mill' s tailings system as 1 le.(2) byproduct material
since 2008.
Concentration and Purification of the Uranium Precipitate
The Uranium Precipitate does not meet the specifications required for acceptance at a uranium conversion facility
due to its moisture content, its elevated iron content, and the presence of other impurities indicated in the
analytical data. It therefore requires further concentration and purification at the Mill in order to produce
yellowcake that meets commercial specifications. It should be emphasized that all of the impurities are typical
of uranium ores and are well within the concentrations of the constituents that are present in and removed from
ores, reprocessed yellowcake, and alternate feed materials at the Mill. The Table in Attachment 2 compares the
levels of impurities in the Uranium Precipitate to those of other feeds historically processed at the Mill.
Letter to Mr. Ty L. Howard
April 30, 2020
Page 6
The United States Nuclear Regulatory Commission ("NRC") has concluded that concentrating and purifying
yellowcake in these circumstances is uranium milling and that the resulting wastes are 1 le.(2) byproduct material.
In Staff Requirements — SECY-02-0095 — Applicability of Section 1 le.(2) of the Atomic Energy Act to Material
at the Sequoyah Fuels Corporation Uranium Conversion Facility, NRC concluded that wastes generated at the
front end of the Sequoyah Fuels Corporation conversion facility ("SFC") that resulted from the further
concentration and purification of yellowcake that it had received from uranium mills can be classified as 1 le.(2)
byproduct material. In that decision, the Commission accepted NRC Staff s position that "The staff has not found
it necessary to label the feed for each step of the milling process as "ore" as the basis for classifying the waste
from that step as 1 le.(2) byproduct material. When yellowcake underwent additional concentration at the front
end of SFC, it was a continuation of uranium milling, i.e., another step of the milling process. Thus, that part of
the processing at a conversion facility fulfills the "extraction or concentration" terms of 1 1 e.(2) byproduct
material."' Unlike SFC, the Site does not have a front-end concentration and purification stage, and therefore
must send the Uranium Precipitate to the Mill to perform this final stage of uranium milling. As indicated by
NRC Staff, and adopted by the Conmiission, "[the Office of the General Counsel] has advised the staff that the
definitions of uranium milling and 1 le.(2) byproduct material are process-related definitions and not restricted to
a particular location of activity nor the physical characteristic of a material."' In fact, NRC Staff noted a number
of circumstances where uranium mills in the past each performed a part only of the uranium milling process and
then shipped the resulting produced material or concentrates to another licensed facility for further milling. NRC
Staff noted that "[e]ach of these mills and several others accomplished only a portion of the milling process at
dispersed locations but were all licensed operations at one time."'
Concentrating and purifying the Uranium Precipitate at the Mill is therefore another step of the uranium milling
process, and all wastes associated with such milling are classified as 1 le.(2) byproduct material and can be
disposed of in the Mill's tailings cells.
Disposal
As determined by NRC in Sequoyah, all wastes associated with further concentration and purification of
yellowcake can be classified as 1 le.(2) byproduct material. Since the concentration and purification of the
Uranium Precipitate at the Mill involves the same steps in the milling process as for other uranium product, the
purification to be performed at the Mill is a continuation of the milling process begun at the Site, and all wastes
associated with the milling will be the same as wastes associated with concentration and purification of
yellowcake at the Mill. The same can be said for the Supersaks®. The Mill routinely disposes of Supersaks®
from the various sources listed above as 1 le.(2) byproduct material in its tailings cells. Since there are no new
or additional constituents in the Uranium Precipitate and associated Supersaks®, there will be no human health,
environmental, or worker safety impacts due to new or additional constituents above those already managed at
the Mill.
The Uranium Precipitate is Source Material and not an Alternate Feed Material
The Uranium Precipitate is source material that is being transferred to the Mill under 10 CFR 40.5 1 and the Mill
License and will be further concentrated and purified as a step in the uranium milling process. It is not an "ore"
and hence is not an alternate feed material. In fact, in its recommendation to the Commission in the Sequoyah

decision, NRC Staff noted that "[w]hether the incoming source material to SFC meets the definition of "ore" is
not relevant to the argument of waste classification. Declaring an incoming feed for individual milling-process
stages as "ore," throughout the continuum of milling, is an artificial and unnecessary distinction. When milling
is done at one site, the feed for each stage is not considered when making 1 1 e.(2) byproduct material
determinations for the classification of wastes for each stage. Similarly, uranium milling has, and does, occur at
different locations under regulatory oversight without the construct of individual processing feeds meeting the
definition of "ore." Thus, there is no need to consider the feed at SFC as ore, because the front-end process at
SFC was simply the last step in the milling activity." This issue was discussed in detail in EFRI's submittal to
Utah DRC on July 26, 20 1 3, which addressed the Mill's proposed receipt as source material of a similar off-spec
yellowcake product from Honeywell, Inc.
Conclusion
The Uranium Precipitate can be received at the Mill as a licensee-to-licensee transfer of source material under 1 0
CFR 40.5 1 (5) and the Mill License. The Uranium Precipitate can be further concentrated and purified at the Mill
as a step in the uranium milling process in order to produce yellowcake that meets commercial specifications.
All wastes from such concentration and purification can be disposed of in the Mill's tailings cells as 1 1 e.(2)
byproduct material. As the Uranium Precipitate is not an "ore" it is not an alternate feed material, and hence an
amendment to the Mill License is not required.
Further, there are no additional environmental, health, or safety concerns associated with the receipt of the
Uranium Precipitate, or the concentration, purification, precipitation, drying and packaging of the Uranium
Precipitate and the disposal of the SuperSaks® in the Mill's tailings cells. The Uranium Precipitate has the same
chemical composition as other intermediate streams produced in the Mill, and the associated SuperSaks® are the
same type of conveyance received and disposed of at the Mill on a regular basis. No additional or new chemicals
or reagents will be used in the process. The concentration and purification of the Uranium Precipitate will result
in the recycling of uranium values that would otherwise be disposed of in the Mill's tailings system, and will
reduce the radionuclide content of the 1 1 e.(2) byproduct material to be disposed of after the recovery of the
uranium values in the Mill.
Please advise us as soon as possible whether you concur with EFRI' s determinations as described in this letter.

ACZ Project ID: L94161
ACZ Laboratories, Inc. (ACZ) received 1 sediment sample from Uraniurn Resources Inc. on April 20, 2012. The sample was received in good condition. Upon receipt, the sample custodian removed the sample from the cooler, inspected the
contents, and logged the sample into ACZ's computerized Laboratory Information Management System (LIMS). The sample was assigned ACZ LIMS project number L94161. The custodian verified the sample information entered into the computer against the chain of custody (COC) forms and sample bottle labels.
All analyses were performed within EPA recommended holding times except for the BNA analysis flagged with an "HC" and an "N1". The initial analysis was performed within the hold time but due to a QC failure, the sample was rerun outside of the hold time. The re-analysis confirmed the original values.
This sample was analyzed for inorganic, organic, radiochemistry parameters. The individual methods are referenced on both, the ACZ invoice and the analytical reports. The following anomalies required further explanation not provided by the Extended Qualifier Report:
1. The sample was received outside of the recommended temperature range of 0 to 6 degrees C.
2. For the Isotopic Uranium values flagged with an "Nl", the PBS was over the control limits. The samples were approved since they were at least ten times the PBS value.
3. For the Isotopic Uranium values flagged with an "NIA", the sample had a very low tracer yield due to very high uranium
content. The peaks had very good shape so the data was flagged and accepted.

fli e Receipt

ACZ Laboratories, Inc. (ACZ) received 1 sediment sample from Uranium Resources Inc. on May 24, 2013. The sample was
received in good condition. Upon receipt, the sample custodian removed the sample from the cooler, inspected the
contents, and logged the sample into ACZ's computerized Laboratory Information Management System (LIMS). The sample
was assigned ACZ LIMS project number L12277. The custodian verified the sample information entered into the computer
against the chain of custody (COC) forms and sample bottle labels.
Holding Times
All analyses were performed within EPA recommended holding times.

This sample was analyzed for inorganic, organic, radiochemistry parameters. The individual methods are referenced on
both, the ACZ invoice and the analytical reports. The following anomaly required further explanation not provided by the
Extended Qualifier Report:
1. For Isotopic Uranium values flagged with an "Nl", the sample was diluted due to matrix interferences (high sample
activity), the columns became over-saturated and the tracer was lost.
