Transmittal of Revised Standard Operating Procedures ("SOPs") and Response to Division of
Radiation Control ("DRC") Request for Information of August 4, 2011 Regarding 11.e(2) Byproduct
Disposal SOP
Dear Mr. Lundberg:
This letter transmits Denison Mines (USA) Corp's proposed revisions to the White Mesa Mill 11 e.(2)
Byproduct Disposal SOP in response to DRC's letter of August 4, 2011, which we received on August 11,
2011. This ALigust 4, 2011 letter contained one comment, detailed below, regarding Item No 4 of our May 31,
2011 letter and draft revisions to the SOP. We have attached an edited redline copy ofthe SOP in which
Denison's modifications or additional language in response to DRC's comment are indicated in a second
color.
We have discuss^lj the comment in DRC's August 4, 2011 letter with Mr. David Rupp, who indicated that
although our draft revisions to the SOP attempted to address Item No. 4, the response letter was unclear or
incorrectvr He indicated that Denison needed to:
a) Correct the letter's quotation of DRC's comment, and
b) Modify the SOP and attachment, as necessary, to more exactly address each word in the license
conditions referred to in DRC's comment
We have re-quoted below, DRC's comment on Item No. 4, and revised our response.
DRC Comment
"Item No. 4 of your May 31, 2011 letter appears to not fully respond to DRC comment no. 4 in the subject
April 21, 2011 DRC letter."
For ease of reference. Comment No. 4 of DRC's April 21, 2011 letter is also provided below in its entirety.
"License Condition 10.5E states that,
The licensee shall also submit for Executive Secretary approval a revised written Standard Operating
Procedure (SOP) for ISL disposal on or before December 1, 2010. The revised SOP shall describe the
documentation required for ISL disposal, which shall include but is not limited to the following...'

DRC Findings: The emphasis here is on documentation. License Condition 10.5D also requires
documentation, "of all disposal activities." DUSA must develop a form for ISL disposal
documentation, to cover all the documentation requirements of License Condition 10.5E and 10.5D."
Denison Response: The revisions have been made as requested. The proposed language has been
accepted with the additional text shown in color in Section 10.0 of the SOP. A form has been added as
Attachment 2 of the SOP.
We hope this clarifies any confusion that resulted from our former response to Comment No. 4.
Please contact me if you have any questions or require any further information.
Yours very truly,

Page 1 of 11
1.0 Purpose
Denison Mines (USA) Corp. ("DUSA") receives lle.(2) byproduct material ("byproduct material")
from uranium in-situ leach operations for disposal under License Condition 10.5. The follovving
procedure applies to acceptance, handling, and disposal of byproduct material at the White Mesa Mill
(the "Mill").
2e0 Prior to Shipment of Byproduct Material
All byproduct material must be approved for disposal by the Mill Radiation Safety Officer ("RSO"), or
his designee, prior to shipment to the Mill. The byproduct material must conform to Titles 10 and 49
of the U.S. Code of Federal Regulations ("CFR") and the Shipper must certify that the byproduct
material does not contain hazardous waste as defined in the Resource Conservation and Recovery Act
("RCRA").
Information regarding the byproduct material to be disposed of should be received prior to receipt of
the shipment at the Mill, and shall include:
1. The volume of material in cubic feet or yards, or quantity of drums and their size.
2. A description of the material (e.g. sludge, process materials, filter media, pipe, etc.)
3. A description of the shipping container (i.e. end dump trailer, intermodal container, side dump
container, etc.)
4. Results of analysis for Unat, Ra-226, Th-230 and Pb-210 on all sludges and soils and other
material that is suited to sample collection. If a representative sample of the material was
taken in connection with a previous shipment of material, then the results of that previous
representative sample may be relied upon, and may be referred to or restated in the
documentation that accompanies the shipment of the material. For byproduct material which
is not suited to sample collection (i.e. metals, process equipment, filter media, pipes, etc.) the
Shipper will determine the range, the average and the total activity, measured in millirem/hour
(mr/hr) at a range of one meter, for each shipment.
5. A copy of the completed shipping manifest that will accompany the shipment and the
anticipated shipping date.
The RSO will also verify, prior to receipt of any shipment of byproduct material, that the disposal of
such byproduct material will not cause the Mill to exceed the Umit of 5,000 cubic yards of byproduct
material from a single source, set out in Mill License condition 10.5A
3.0 Designated Disposal Area
The RSO will designate from time to time one or more designated disposal areas (each a "Designated
Disposal Area") being a general area within a tailings cell for the disposal of byproduct material. Each
Designated Disposal Area must meet the following criteria:

1. The Designated Disposal Area must be in an active tailings cell (i.e., a tailings cell that is not
fully covered with interim cover);
2. The Designated Disposal Area must be on a tailings beach area of the cell or on an area of the
cell that is underlain by tailings sands;
3. There must be at least 4 feet of tailings sands under the Designated Disposal Area;
4. The Designated Disposal Area must be located at least 12 feet from the sides or dikes of the
tailings cell;
5. The elevation of the Designated Disposal Area once filled with byproduct material must not
exceed the plane or grade of the elevation of the uppermost flexible membrane liner of the
tailings cell;
6. Detailed engineering drawings must have been prepared and kept on file at the Mill that
demonstrate for each Designated Disposal Area that:
a) There are at least 4 feet of tailings sands under the bottom of the Designated Disposal Area;
and
b) The bottom of the Designated Disposal Area is located at least 12 feet from the sides or dikes
of the tailings cells; and
7. Prior written approval must have been obtained from the Executive Secretary of the Utah
Radiation Control Board (the "Executive Secretary") for each Designated Disposal Area, under
Mill License condition 10.5C, and evidence of such approval must be on file at the Mill.
8. Byproduct material from each ISL facility is disposed in Designated Disposal Areas specific to
that ISL facility. Designated Disposal Areas include either trench areas or tailings beach areas.
The procedures for placement are not dependant on which area the byproduct material is placed
in. The above procedures are the same for both trench areas and tailings beach areas.
4.0 Notification to Executive Secretary
DUSA shall notify the Executive Secretary in writing at least 7 calendar days prior to the proposed
scheduled date for disposal of any byproduct material. Written evidence of this notification will be
kept on file at the Mill. |

Forms will be tumed in to the Safety Department for future reference.
2. Inspect all copies of the Shipping Manifest and the transporter's Bill of Lading to ensure that
the shipment is destined for the Mill and confirm with the RSO that the shipment has been
approved for receipt.
3. Record the inbound date and both the truck and trailer numbers on the Scale house Weight
Ticket (SWT).
4. Enter the loaded weight of the truck and trailer on the SWT.
5. The scale house operator will contact the Radiation Safety Department so that the shipment
can be escorted by Radiation Safety personnel to the Designated Disposal Area specified by
the RSO.
6. Prior to transporting material to the Designated Disposal Area, the driver will be instructed to
open or untarp the load. The Radiation Safety personnel will visually inspect, to the degree
possible, the byproduct material to ensure that the material matches the material description on
the shipping manifest. Any discrepancies between the byproduct material received and the
manifest information will be reported to the RSO.
a. Any byproduct material suspected of not conforming to Section 2.0 of this SOP will
not be transported to the disposal site, unless a determination is made by the RSO
that the material in question conforms to Section 2.0 of this SOP.
b. Barrels containing soil or sludges shall be checked to determine if they are full prior
to transporting them for disposaL Barrels not completely full shall be documented
and shall be filled with tailings or soil prior to disposal. (License Condition 10.5.B).
6.0 Byproduct Material Unloading
1. The RSO will specify the specific location within the broader Designated Disposal Area for
disposal of the shipment. In designating the specific location within the broader Designated
Disposal Area for disposal of the shipment, the RSO will ensure that all byproduct material will
be segregated from any Mill material and equipment disposed of in the cell pursuant to Mill
license condition 10.4, and that the byproduct material from each ISL source will be segregated
from the byproduct material from all other ISL sources.
2. Radiation Safety personnel will escort the shipment to the designated location in the
Designated Disposal Area for unloading of the byproduct material.
3. Proposed Methods and Procedures to Fully Protect the Liner While Accessing Tailings
Cells for Disposal of ISL Byproduct Material and Mill Equipment

unprotected dikes, liners, other structures or settlement monitors associated with any of the
tailings cells.
c. There must be at least 4 feet of tailings sands under the Designated Disposal Area
(documentation of the disposal area must be completed and on file prior to any disposal
activities);
d. The Designated Disposal Area must be located at least 12 feet from the sides or dikes of
the tailings cell (documentation of the disposal area must be completed and on file prior to
any disposal activities);
e. No travel into the disposal area will be allowed unless the disposal cell liner is covered
by at least 18 inches of soil or fill material at the point of access.
4. If the 7 calendar day notice referred to in Section 4.0 above has not been given, or the 7 days
have not lapsed, then the shipment may be, but is not required to be contained in the shipping
container on site until the required 7 day notice has been given and the 7 calendar days have
lapsed.
5. If the shipment is determined to be acceptable, the following procedures will be followed:
a) If the 7-day notice has been given under Section 4.0 above and the 7 calendar days have lapsed,
the byproduct material will then be unloaded in the designated area. If such notice has not been
given or if such 7 day period has not lapsed, then the byproduct material will be unloaded in an
area of the tailings cell that is not covered with interim cover and from which the material can
be removed if necessary. Once the required notice has been given and the required 7 days have
lapsed, the byproduct material will then be placed into the designated area.
b) If the material is in a self-unloading container, the driver will be instructed to unload ensuring
all personnel are clear of the trailer and the immediate area. Byproduct material will be
dumped from the transport in a safe manner to minimize dust. If the material requires
unloading by a fork truck, a ramp will be installed and unloading will proceed.
c) After unloading,' the Radiation Safety personnel will visually inspect the unloaded byproduct
material to ensure that there is no newly discovered material which does not match the material
description on the shipping manifest. Any discrepancies between the byproduct material received and
the manifest information will be reported to the RSO. Any byproduct material suspected of not
meeting the requirements set forth in Section 2.0 of this SOP will be kept segregated from other waste
material until a determination is made of its acceptability for disposal.
d) After unloading, a photo of the unloaded material will be taken which is attached to the
shipping documentation for verification of shipment contents.
e) The location of the shipment of the byproduct material will be documented on the plat of each
Designated Disposal Area illustrating the disposal area within the Designated Disposal Area
where the byproduct material will be disposed of.
f) Beta-gamma measurements will be taken at several locations around the unloaded material.
This information will be recorded on the Radiation Department's copy of the shipment
documentation. The measurement range in mrem/hr at 1 meter, and the average measurement,
measured in mrem/hr at 1 meter, shall be recorded.

PageSof 11
g) Measurements using a photoionization detection meter ("PID") will be taken at several
locations around the unloaded material to ensure that there are no organics present. The
information will be recorded on the Radiation Department's copy of the shipment
documentation. If organics are detected, the RSO must be advised, and no compaction or
covering activities relating to the shipment shall occur until specifically instructed by the RSO.
The RSO will determine if any additional safety precautions are required to be taken by
workers or otherwise as a result of the detection of the organics, and will implement any such
precautions. The RSO will also contact DUSA corporate regulatory personnel and the shipper
to verify that the detected organics are lle.(2) byproduct material from the shipper's ISL
facility. Once the RSO has verified that the organics are byproduct material compaction and
covering activities will proceed.
h) A breathing zone sample will be taken periodically during unloading and cover activities. If
the gross alpha exceeds 25% of the applicable DAC, then the RSO will be notified, and all
other unloading activities of byproduct material from that particular ISL site will require the
use of respiratory protection, until further notice by the RSO.
i) After unloading the byproduct material, replace the tarp or close the trailer, unless the trailer is
being decontaminated for unrestricted release.
j) Direct the driver back to the scales for an empty weight.
k) The scale house operator will record the empty weight on the appropriate SWT.
1) Shipment and disposal activities will be documented as described in Section 10, below.
7.0 Covering of Byproduct Material
1. After the byproduct material has been accepted by the RSO, or his designee, the byproduct
material will be spread within the designated area within the Designated Disposal Area to
facilitate compaction and covering.
2. The byproduct material will be compacted with at least four passes of the construction
equipment prior to placing an additional layer.
3. Free volumes in the byproduct material will be minimized by filling, sectioning, or crushing.
Random fill or tailings sands will be used to fill voids in and around the byproduct material.
4. All contaminated equipment shall be dismantied, crushed, or sectioned to minimize void
spaces. Barrels containing waste other than soil or sludges shall be emptied into the disposal
area and the barrels crushed. Barrels containing soil or sludges shall be verified to be full prior
to disposal. Barrels not completely full shall be filled with tailings or soil.
5. A one foot thick, or thicker, cover comprised of native soil will be placed over the byproduct

material working area. The fill and cover material will be compacted with at least one pass of
the construction equipment.
6. The RSO or his designee will inspect the placement of the byproduct material prior to covering
to physically verify that the procedures in this Section 7.0 have been adequately performed.
8-0 Decontamination and Release of Trailers and Trucks
All trailers and trucks v^ill be decontaminated after unloading prior to leaving the Mill. Shippers
or transporters will notify DUSA whether a specific trailer is to be released for restricted or
unrestricted use. Any trailers that are to be released for restricted use will be decontaminated
according to the requirements contained in DOT Part 49 CFR 173.441(b) and 173.443. Any trailers
that are to be released for unrestricted use will be decontaminated according to the requirements found
in Table 1 ofthe Nuclear Regulatory Commission's (NRC's) Policy and Guidance Directive FC-85-23,
"Guidelines for Decontamination of Facilities and Equipment Prior to Release for Unrestricted Use or
Termination of Licenses for Byproduct, Source, or Special Nuclear Material" issued May 1987.
Trailers requiring repair will be decontaminated for unrestricted release, to facilitate repairs by the
transporter at the transporter's own site. Trailers may be repaired without undergoing full
decontamination if repaired within the restricted area of the Mill.
For the appropriate decontamination procedures, refer to the following Standard Operating Procedures
for the appropriate conveyance:
End Dump Trailer SOP PBL-9
Intermodal Container SOP PBL-2
Standard Container Trailer SOP-PBL-2
9.0 Hazard Identification and Safety
1. Required Personal Protective Equipment (PPE)
In all areas of the Mill covered by this procedure, hard hats, safety glasses and steel-toed shoes
are required at a minimum. These must be worn in the restricted area of the Mill. Prior to
disposal, the RSO will determine what level of respiratory protection, if any, will be required.
2. Industrial Hazards and Safety
c) Use caution when the trailers are backing to the unloading area.
d) Ensure that all personnel within 50 feet of the area where an end dump trailer is about to dump
its load are aware that unloading is about to commence. Move at least 25 feet away from the
rear of the trailer during the initial unloading operation.
e) Drivers must use caution during the unloading process and be aware of any overhead hazards.

3. Proposed Methods and Procedures to Fully Protect the Liner While Accessing -
Tailings Cells for Disposal of ISL Byproduct Material and Mill Equipment
a. The shipment will be transported to the Designated Disposal Area ^
only on established roadways onto the tailings cells.
h, At no time will a shipment be transported over or in a manner that
will damage unprotected dikes, liners, other structures or settlement monitors
associated with any of the tailings cells.
c. There must be at least 4 feet of taihngs sands under the Designated
Disposal Area (documentation of the disposal area must be completed and on
file prior to any disposal activities):
d. The Designated Disposal Area must be located at least 12 feet
from the sides or dikes of the taihngs cell (documentation of the disposal area
must be completed and on file prior to any disposal activities);
^ e. No travel into the disposal area will be allowed unless the disposal
cell liner is covered by at least 18 inches of soil or fill material at the point of
access.

information will be reported to the RSO. Any byproduct material suspected of
not mooting the requirements set forth in Section 2.0 of this SOP will bo kept

acceptability for disposaL
Jf the 7 calendar day notice referred to in Section 4.0 above has not been given, or
the 7 days have not lapsed, then the shipment may J3e, but is not required to be
contained in the shipping container on site until the required 7 day notice has been

6.5. _If the shipment is determined to be acceptable^ the following procedures will be
followed:
a) If the 7-day notice has been given under Section 4.0 above and the 7 calendar
days have lapsed, the byproduct material will then be unloaded in the designated
area. If such notice has not been given or if such 7 day period has not lapsed, then
the byproduct material will be unloaded in an area of the tailings cell that is not
covered with interim cover and from which the material can be removed if
necessary. Once the required notice has been given and the required 7 days have
lapsed, the byproduct material will then be placed into the designated area.
b) If the material is in a self-unloading container, the driver will be instructed to
unload ensuring all personnel are clear of the trailer and the immediate area.
Byproduct material will be dumped from the transport in a safe manner to
minimize dust. If the material requires unloading by a fork truck, a ramp will be
installed and unloading will proceed.
c) After unloading, the Radiation Safety personnel will visually inspect the unloaded-^
byproduct material to ensure that there is no newly discovered material which
does not match the material description on the shipping manifest. Any
discrepancies between the byproduct material received and the manifest
information will be reported to the RSQ. Any byproduct material suspected of
not meeting the requirements set forth in Section 2.0 of this SOP will be kept
segregated from other waste material until a determination is made of its
acceptability for disposal.

f) Beta-gamma measurements will be taken at several locations around the unloaded*
material. This information will be recorded on the Radiation Department's copy
of the shipment documentation. The measurement range in mrem/hr at 1 meter,
and the average measurement, measured in mrem/hr at 1 meter, shall be recorded.
g) Measurements using a photoionization detection meter ('TID") will be taken at*
several locations around the unloaded material to ensure that there are no organics
present. The information will be recorded on the Radiation Department's copy of
the shipment documentation. If organics are detected, the RSO must be advised,
and no compaction or covering activities relating to the shipment shall occur until
specifically instructed by the RSO. The RSO will determine if any additional
safety precautions are required to be taken by workers or otherwise as a result of
the detection of the organics, and will implement any such precautions. The RSO
will also contact DUSA corporate regulatory personnel and the shipper to verify
that the detected organics are lle.(2) byproduct material from the shipper's ISL
facihty. Once the RSO has verified that the organics are byproduct material
compaction and covering activities will proceed.
h) A breathing zone sample will be taken periodically during unloading and cover*
activities. If the gross alpha exceeds 25% of the applicable DAC, then the RSO
will be notified, and all other unloading activities of byproduct material from that
particular ISL site will require the use of respiratory protection, until further
nodce by the RSO.
