We have reviewed this response. The subject DRC comment letter, dated August 4, 2011, had a single comiiient. It stated that, "Item No'. 4 of your May 31, 2011 letter appears to not fully respond to DRC comment no. 4 in the subject April 21 j 2011 DRC letter." The April 21, 2011 DRC letter, comment no. 4, stated that, ".. .DUSA must develop a form for ISL disposal documentation requirements of License Condition 10.5E and 10.5D." The primary focus of this letter is to assure that the related documentation requirements are captured on the form. 1 However, the form appears to be proposed as a checklist by DUSA, and the documentation requirements and needed references are not always included on the form. | In some cases, additional verbiage needs to be added to the body of the SOP for the form to reference tlie various License Condition requirements. -1 Our comments follow below pertain to License Conditions 10.5E, 10.5D and some additional comments: I. License Condition 10.5E states, / ' . "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:" ! 195 North 1950 Wesl • Salt Lake City, UT Maihng Address: P.O.

There are at least 4 feet of tailings sands under the bottom of each disposal area; and "b. The bottom of each disposal area is located at least 12 feet from the sides or dikes of the tailpigs cell." The for^ enclosed in Attachment 2 of the subject September 12, 2011 DUSA letter was proposed to fulfill the requirements above. It appears that in some cases, additional verbiage will need to be added to the body of the SOP for said form to reference, in order to fulfill these requirements. We note the following: A. License Condition 10.5E(2) is not captured on the form. The form needs to call for or make reference to the required documentation of a survey and review, or other documentation, that will show the specific requirements of License Condition 10.5E(2) have been met. It does not appear this requirement is captured in the body of the SOP. B. License Condition 10.5E(3) is not completely captured on the form. The form needs to call for or make reference to the required documentation to demonstrate that ISL material is segregated from both disposed mill material/equipment as well as all other in-situ leach sources. It appears that the form needs to make reference to: i) . The plats of the designated ISL byproduct material disposal areas mentioned in the SOP. ii) . Plats of the disposed mill material and equipment, which demonstrates segregation from the ISL material. These may be separate or joint plats containing the separation information. It does not appear this entire requirement is captured in the body of the SOP. C. License Condition 10.5E(4) is not completely captured on the form. The form needs to call for or make reference to the required documentation of an examination and filling the pertinent barrels and other documentation, that will demonstrate that all disposed barrels meet the specific requirements of License Condition 10.5.E(4). This item is tied to License Condition 10.5B, which states that, "Barrels containing soil or sludges shall be verified by the Licensee to be full prior to disposal. Barrels not completely full shall be filled with tailings or soil prior to disposal." It does not appear that documentation requirement for this is captured on the form. D. License Condition 10.5.E(5) appears to not be fully captured on the form. The form needs to call for or make reference to the required detailed engineering drawings that demonstrate that the dimensional clearance requirements as stated in License Condition 10.5.E(5), for each disposal area are met. Although it appears the body of the SOP contains this requirement, it does not appear the form states or references the documentation required. Page 3 II. License Condition 10.5D states that, "All disposal activities shall be documented and records thereof maintained on-site. The documentation shall include descriptions ofthe ISL waste and the disposal locations, as well as all actions required by this License condition." This License Condition requires documentation of all [ISL] disposal activities in License Condition 10.5, paragraphs A through F. Section I of this letter above is devoted to paragraph 10.5E. License Condition 10.5A and 10.5F are adequately covered. Therefore our comments below are limited to License Conditions, i.e. 10.5B through 10.5.D: A. License Condition 10.5B. Our comment regarding this condition is covered by paragraph LC of this letter. B. License Condition 10.5C is not completely captured on the form. The SOP appears to make partial reference to this condition in paragraph 3.7 of the SOP. The form needs to call for or make reference to the required documentation to assure the complete specific requirements of this License Condition have been met. These complete requirement needs to be added to the body of the SOP as well. C. License Condition 10.5D. Our comments on this license condition are contained in the comments of this letter. III. Additiona] Comments. A. The subject SOP, (i) Paragraph 6.4, the term "shipping container" may be interpreted to refer to several things. It appears the term "shipping container" in this paragraph may be intended to refer to shipping trailers or truck beds. Please define this in the SOP. "Shipping containers" must be defined to not include containers such as sacks or banels. (ii) Paragraph 10.2b, the second bullet, after the words "void spaces," the phrase "in barrels containing soil and sludges," must be added.

HERBERT Governor GREG BELL Lieutenant Governor April 21, 2011 CERTIFIED MAIL (Retum Receipt Requested) Ms. Jo Ann Tischler Director, Compliance and Permitting Denison Mines (USA) Corp. (DUSA) 1050 Seventeenth Street, Suite 950 Denver, CO 80265 Dear Ms. Tischler: SUBJECT: December 1, 2010 DUSA Transmittal Letter, Three Separate Draft Standard Operating Procedures (SOPs); SOPs for Title: He.{2} Byproduct Disposal No. PBL-10 Rev. No.: R-2 Dec. 1, 2010: Comments and Request for Information We have received the subject December 1, 2010 DUSA letter, transmitting three separate proposed Standard Operating Procedures (SOPs). The subject of this letter is our review of one of these SOPs, i.e. the Title: lie.(2) Byproduct Disposal Standard Operating Procedures [SOPs] with subject version number. The subject Titie: 1 le.(2) Byproduct Disposal SOPs were submitted by DUSA to comply with the requirements of Liceiise Condition 10.5. We have reviewed this document!, and have comments listed below. DRC review of the other two transmitted SOPs is to be discussed in separate DRC letters. 1. General. a. Please bear in mind that since the items below pertain to a License Condition that requires Executive Secretary approval, your responses regarding them could be subject to enforcement. Therefore, complete and thorough responses in this matter are important. b. Some suggested red-line strike-out changes for the subject SOPs are attached. The majority of these suggestions were derived from our review of the License Conditions. Please note that some sections of the red-line strike-out copy of the subject SOPs may contain several recommended changes. Also, please note that not all changes requested in this letter are captured in our red-line strike-out notations. c. Chief among the interests of DRC in changes to the subject SOPs was for DUSA to add provisions to prevent the occurrence of any hazardous waste deposits, and to increase density of compacted ISL byproduct materials (to reduce potential settlement) in tailings cells. Remarks, l.c. (1) through (3) directiy below, concern this. (1). We suggest DUSA consider adding the verbiage similar to that shown in red-line strike-out verbiage attached as new red-line paragraph 5.6 of the subject SOPS. 195 North 1950 West • Salt Uke City, UT Mailing Address: P.O. Box 144850'Salt Lake City, UT 84114-4850 , Telephone (801) 536-4250' Fax (801) 533-4097 • T.D.D. (801) 536-4414 www.deq.utah.gov . , • Printed on 100% recycled paper Page 2 The concept is to have byproduct materials pre-inspected before its arrival adjacent to the disposal site. • . - - v. (2) . As shown in red-line, we suggest that DUSA consider moving existing paragraph 6.4 and revise it to language similar to the attached new red-line paragraph 6.5.c of the subject SOPs. The concept here is to assure after unloading, that no items of concem were hidden or obscured in the material. (3) . To be consistent with License Condition 10.4A, and to increase compaction and reduce settlement, as mentioned in paragraph lc above, we have a comment. We suggest DUSA edit paragraph 7.2, similar to the attached red-line strike out verbiage of the subject SOPs, to require that, "byproduct material will be compacted with the same requirements as License Condition 10.4A." License Condition 10.5B states that, "All ISL contaminated equipment shall be dismantled, 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 by the Licensee to be full prior to disposal. Barrels not completely full shall be filled with tailings or soil prior to disposal." DRC Findings: Some red-line strike-out verbiage attached is suggested in Section 5.6b of the subject SOPs. The concept is to have barrels containing byproduct materials pre- inspected for fullness before arrival adjacent to the disposal site. License Condition 10.5E(3) states that, - ".. .ISL byproduct material will be segregated from any mill material and equipment disposed of in the cells pursuant to License Condition 10.4, and the ISL byproduct material from each in-situ leach source will be segregated from the byproduct material from all other in-situ leach sources;" DRC Findings: It appears the submitted SOPs do not clearly address this condition. Some red-line strike-out verbiage attached is suggested in Section 6.1 of the subject SOPs to more clearly address this license condition. 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. Page 3 5. The DRC review letter of March 1, 2010 is referenced in your subject transmittal. Paragraph A of the DRC letter states the following: "Proposed methods and procedures to fully protect the liner while accessing tailings cells for disposal of ISL byproduct material and mill equipment must be submitted for approval. These methods and procedures would apply to tailings Cell 4A and newer cells." DRC Findings: It appears the submitted SOPs do not describe the actual "methods and procedures to protect the liner while accessing the tailings cells..." Please adjust the subject SOPs to do so. 6. The page numbering in the subject SOPs document has errors. Please adjust the subject SOPs to correct these errors. 7. DRC RAM Inspector Comments: a. Reference a DRC inspection of ISL disposal activities, held on September 1-2, 2009. A copy of the inspection report is attached to this letter. In the "Deficiencies" paragraph on page 2 of this report, the DRC inspector stated that at that time, the ISL documentation did not include, "Description of how ISL material [was] being placed in the slit trenches..." and, "Description of other activities (i.e. Barrels not being completely full being filled with tailings or soil as described in License Condition 10.5B)." In the Conclusions and Recommendations paragraph on page 4 of that report, it states that DUSA should , "Document the placement of ISL material in tailing Cell #3 with a detailed description [ofl all dispos;al activities involved with the disposal of each shipment. License Condition 10.5D states,'All disposal activities shall be documented.'" The disposal documentation for each shipment, including the method of disposal such as trench disposal or other approved disposal method with backfill, needs to be documented for each individual shipment. Documentation requirements for the above activities were not included in the subject SOPs as submitted, but need to be. b. Balloon comments Rl through R4 are provided in the rnargins of the attached red-line strike out copy of the subject SOPs. Please address these comments. Please review the above conrmrients, and respond in writing, submitting an appropriately revised Title: 1 le.(2) Byproduct Disposal Standard Operating Procedures document with a unique version number. Per your email dated April 14, 2011 you committed that DUSA would fully respond to this letter within 30 calendar days of receipt. If you have any questions on the above, please contact me.

The form enclosed in Attachment 2 of the subject September 12, 2011 DUSA letter was proposed to fulfill the requirements above. lt appears that in some cases, additionalverbiage will need to be added to the body of the SOP for said form to reference, in order to fulfillthese requirements. We note the following: A. License Condition 10.5E(2) is not captured on the form. The form needs to callfor or make reference to the required documentation of a suruey and review, or other documentation, that will show the specific requirements of License Condition 10.5E(2) have been met. lt does not appear this requirement is captured in the body of the SOP. Denison Response: A line item has been added to the form referencing the survey or review to confirm the elevation limit will not be exceeded. B. License Condition 10.5E(3) is not completely captured on the form. The form needs to callfor or make reference to the required documentation to demonstrate that ISL materialis segregated from both disposed mill material/equipment as well as allother in-situ leach sources. It appears that the form needs to make reference to:i). The plats of the designated ISL byproduct materialdisposal areas mentioned in the SOP. ii). Plats of the disposed mill material and equipment, which demonstrates segregation from the ISL material. These may be separate or joint plats containing the separation information. lt does not appear this entire requirement is captured in the body of the SOP. Denison Response: Line items have been added to the form and text has been added to the SOP referencing plats or figures demonstrating that the ISL material has been properly segregated from other wastes. C. License Condition 10.5E(4) is not completely captured on the form. The form needs to call for or make reference to the required documentation of an examination and filling the pertinent barrels and other documentation, that will demonstrate that all disposed barrels meet the specific requirements of License Condition 10.5.E(4). This item is tied to License Condition 10.58, which states that, "Barrels containing soil or sludges shall be verified by the Licensee to be full prior to disposal. Barrels not completely full shall be filled with tailings or soil prior to disposal." lt does not appear that documentation requirement for this is captured on the form. Denison Response: Line items requiring that the barrels be inspected for voids and that voids be filled have been added to the form as requested. D. License Condition 10.5.E(5) appears to not be fully captured on the form. The form needs to call for or make reference to the required detailed engineering drawings that demonstrate that the dimensionalclearance requirements as stated in License Condition 10.5.E(5), for each disposal area are met. Although it appears the body of the SOP contains this requirement, it does not appear the form stafes or references the documentation required. The requirements referring to documentation addressing dimensional clearance have been added to the form as required.

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.

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/tr at 1 meter, and the average measurement, measured in mrem/tr at 1 meter, shall be recorded. Measurements using a photoionization detection meter ("PD") 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 IIe.(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. A breathing zone sample will be taken periodically during unloading and cover activities. If the gross alpha exceeds 25Vo 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. After unloading the byproduct material, replace the tarp or close the trailer, unless the trailer is being decontaminated for unrestricted release. Direct the driver back to the scales for an empty weight. The scale house operator will record the empty weight on the appropriate SWT. Shipment and disposal activities will be documented as described in Section 10, below.r) Coverins of Bvoroduct lVlaterial After the byproduct material has been accepted by material will be spread within the designated area facilitate compaction and covering.

All contaminated equipment shall be dismantled, 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. 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. 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. Decontamination and Release of Trailers and Trucks 4. 5. 6. All trailers and trucks will 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 113.443. Any trailers that are to be released for unrestricted use will be decontaminated according to the requirements found in Table 1 of the 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 Intermodal Container Standard Container Trailer SOP PBL-9 SOP PBL-2 SOP-PBL-2 9.0 Hazard Identification and Safetv 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.

This letter also responds to DRC's letter of April 21, 2011, which we received onApril 28, 2011 providing DRC's proposed redlines and comments on the subject SOP. We have attached an edited redline copy of the SOP in which Denison's modifications or additional language in response to DRC comments are indicated in a second color. We have provided, below, specific responses to each request in DRC's April 21, 2011 letter. The sectionsand numbering of the remainder of this letter follow the DRC April 21, 2011 letter. Each DRC request is shown in italics, below, followed by Denison's response. DRC Comments and Responses 1. General.a. Some suggested red-line strike-out changes for the subject SOPs are aftached. The majorityof these suggesfions were derived from our review of the License Conditions. Please note that some sections of the red-line strike-out copy of the subject SOPs may contain several recommended changes. Also, please note that not all changes requested are captured in our red-l i n e stri ke-o ut n otatio n s. Denison Response: So noted. Denison has also replied to the four additional DRC comments provided inthe margins of the SOP. Our responses are provided in the margins of the SOP directly below thecomments. As general background to our response to DRC's comment in the margin of Section 3.0 of the SOP, Denison feels it is important to clarify that trench disposal and tailings beach disposal are not two different types of disposal. The disposal location for material from each ISL source is pre-determined by the RSO as a Designated Disposal Area for that source. Designated Disposal Areas were selected primarily to :..1 *7 li !i-'l1 " f ' JU,II 2C1i f lv: ,ioi r:f,xiitrircl i-llritlOI Donison Mines (USA) Corp. 1050 17th Street, Suite 950 Denver, CO 80265 USA Tel : 303 628-7798 Fax : 303 3894125 www.denisonmines.com Re: C:\Users\jtischler\Desktop\SOP repsonse 11e2 monitoMS.2T.ll Responseto DEQ 04.20.11 RFt 11e2 SOp.doc Letter to Mr. Rusty r-unooert) 11e.(2) SOP RFI Response May 31 ,2011 Page2 assure the ability to segregate material from each ISL source, and to ensure that every designated Disposal Area meets the requirements of License Condition 10. E, including the requirement to maintain 4 feet of tailings sands below and 12 feet of clearance between the material and the sides or dikes of the cell, regardless of whether the material is placed in a trench area or beach area. There are no physical differences in the way material is placed in trenches versus beach areas. Therefore, the SOP does not describe two different placement processes because there are not two ditferent placement processes. b. Chief among the interesfs of DRC in changes to the subject SOPs was for DUSA to add provisions to prevent the occurrence of any hazardous wasfe deposifs, and to increase density of compacted ISL byproduct materials (to reduce potential settlement) in tailings cells. Remarks, 1.b. (1) through (3) directly below, concern this. Denison Response: DUSA feels it is important to clarify the issue of "hazardous waste deposits," as well as the DRC comment noted in the margin of the redline SOP regarding whether the "byproduct material meets the RCRA requirements." 1) To be regulated by RCRA as a hazardous waste, a material must be a solid waste per the RCRA definition. Source Material, Special Nuclear Material, and 11e.(2) Byproduct Material are expressly excluded from the definition of solid waste under RCRA (42 USC 6903 and 40 CFR 2il.a@)($. Process wastes and debris from ISL facilities are 11e.(2) byproduct by definition and are therefore excluded from the definition of solid waste, and from the definition of hazardous waste, under RCRA.2) DUSA's license allows us to accept 11e.(2) byproduct material under Conditions 9.8 and 10.5.3) RCRA defines two types of hazardous waste. Hazardous wastes can be either characteristic hazardous wastes (i.e., ignitable, corrosive, toxic, or reactive) or listed hazardous waste (i.e. listed under40 CFR 271.30-33 or undercomparable State law provisions.4) Because 11e.(2) byproduct may include some of the same types of constituents and properties as RCRA characteristic wastes, analysis for RCRA characteristics would not have any value in confirming that a waste is not a RCRA characteristic waste. Because 11e.(2) material is not a solid waste, it cannot be a RCRA characteristic waste.5) Because RCRA listed wastes are determined by source or origin, analysis for RCRA constituents would not have any value determining if the material is a RCRA listed waste. Because the material's process of origin in the processing of source material as defined 10 CFR 40.4, the waste a) is not from any RCRA listed process and b) the waste is 11e.(2) byproduct by definition and cannot be solid waste, and therefore not a RCRA listed waste.6) Because 11e.(2) material is exempted from RCRA due to its origin, no analysis or specific documentation is required. DUSA requires the certification described in Section 2.0 of this SOP as an added assurance that the material consists solely of 11e.(2) byproduct and is not combined with any other material or waste.7) A chemical profile of the material is not required, and not requested from the shipper. The only reason DUSA asks for the radiological characterization is for our own radiological safety assessment by the Mill's RSO. (1). We suggest DUSA consider adding the verbiage similar to that shown in red-line stike-out verbiage aftached as new red-line paragraph 5.6 of the subject SOPs. Ihe concept is to have byproduct materials pre-inspected before its arrival adjacent to the disposa/ sife. Denison Response: The verbiage has been accepted as provided. DENISOND// ftIINES Letter to Mr. Rusty Lundberp 11e.(2) SOP RFI Response May 31,2011 Page 3 (2). As shourn in red-line, we suggesf that DUSA consider moving existing paragraph 6.4 and revise it to language similar to the aftached new red-line paragraph 6.5.c of the subject SOPs. The concept here ls fo assure after unloading, that no items of concern were hidden or obscured in the material. Denison Response: The verbiage has been accepted as provided. (3). To be consrsfenf with License Condition 10.4A, and to increase compaction and reduce seftlement, we suggesf DUSA have paragraph 7.2 be rewritten as shown in the attached red-line strike out verbiage of the subject SOPs, to require that, "byproduct material will be compacted with the same requirements as Lrbense Condition 10.44.' Denison Response: The text change regarding compaction has not been included for the following reasons. License condition 10.4, as cited by DRC in the proposed text change, applies to disposal of material and equipment generated at the Mill site. The License condition applicable to disposal of ISL waste, Condition 10.5, refers to, and is based on, the UMETCO May 20, 1993 letter to the US Nuclear Regulatory Commission. The May 20, 1993 letter, a copy of which has been attached for your reference, states that "Each layer of the waste material will be compacted with at least one pass of the construction equipment prior to placing an additional layer." DRC's proposed language is inconsistent with the License. The existing language in Section 7.2 of the SOP, which is consistent with the License, has been retained. 2. License Condition 10.58 sfafes fhaf, "All ISL contaminated equipment shall be dismantled, crushed, or sectioned to minimize tzold spaces. Barrels containing waste other than soil or s/udges shall be emptied into the dr.sposa/ area and the barrels crushed. Barrels containing soil or s/udges shall be verified by the Licensee to be full prior to disposal. Barrels not completely full shall be filled with tailings or soil prior to disposal." DRC Findinas: Some red-line strike-out verbiage attached ls suggesfed in Section 5.6b of the subject SOPs. The concept is to have barrels containing byproduct materials pre-inspected for fullness before arrival adjacent to the disposa/ sife. Denison Response: DRC's proposed change has been accepted as provided. 3. License Condition 10.5E(il sfafes ffiat ".../SL byproduct material will be segregated from any mill mateial and equipment disposed of in the cells pursuant to License Condition 10.4, and fhe /SL byproduct material from each in-situ leach source will be segregated from the byproduct materialfrom all other in-situ leach sources;" DRC Findinos: lt appears the submifted SOPs do not clearly address this condition. Some red-line strike-out verbiage attached is suggesfed in Section 6.1 of the subject SOPs to more clearly address this license condition. Denison Response: DRC's proposed change has been accepted as provided. 4. License Condition 10.5E stafes fhat "The licensee shall also submit for Executive Secretary approval a revised written DENISOJ)//M!NES Letter to Mr. Rusty f-unOUerp 11e.(2) SOP RFI Response May 31,2011 Page 4 Standard Operating Procedure (SOP) for ISL dlsposa/ on or before December 1,2010.

DRC Findinos: lt appears the submifted SOPs do not capture the documentation requirements of License Condition items 10.5E.(1) through (4). Please adjust the subject SOPs fo do so. Denison Response: The change has been made as requested. The proposed language has been accepted with the additional text shown in an alternate color in Section 6.5i). A form has been provided in Attachment 1 of the SOP. 5. The DRC review lefter of March 1 , 2010 is referenced in your subject transmittal. Paragraph A of the DRC /ettersfafes the following: "Proposed methods and procedures fo fully protect the liner while accessing tailings cells for drsposa/ of /SL byproduct material and mill equipment must be submifted for approval. These methods and procedures would apply to tailings Cell4A and newer cells." DRC Findinos: lt appears the submifted SOPs do not completely capture this item. Please adjust the subject SOPs fo do so. Denison Response: The SOP does, in fact, address "actual methods and procedures to fully protect the liner while accessing the tailings cells." The reviewer is referred to Sections 3.2,3.3,3.4 and 6.3 in the previous version where the methods were discussed. However, the methods and procedures that were already provided in these sections have been combined in a new Section 6.3 entitled "Proposed Methods and Procedures to Fully Protect the Liner While Accessing Tailings Cells for Drsposa/ of /SL Byproduct Material and Mill Equipment." This rearrangement should "fully capture this item." 6. The page numbering in the subjecf SOPs document has errors. Please adjust the subject SOPs fo conect these errors.

A delivery date and estimated arrival time will be established and conveyed to the site personnel involved with the actual receiving and accepting the waste material. A location in the disposal area will be selected, within the US-NRC approval disposal area (Cell 3). The third party waste material's location of disposal will be noted on th€ shipping manifest and waste disposal plat. The manifest and plat will be entered into Umetco's permanent records when the shipment is received and permanently disposed of. The records will be maintained for review by Umetco's NRC personnel. SITE SPECIFIC ACTIVITIES 7. A breathing zone sample will be taken periodically during disposal and cover activities. lf the gross alpha approaches or exceeds 2.5 x 1O-11Ci/ml, then site personnel will be required to notify the Manager of Operations and the RSO. Activities will be suspended and an investigation will be made of the events that lead to the elevated airborne gross alpha activity. Recommenda- tions and modifications to activities required to bury waste will be changed. 4.1 5. 6. 8. 7.1 Employees will be required to wear appropriate protective equipment, as deemed necessary by RSO. 7.2 Transport drivers will have to sign the visitor log and site hazard recog- nition form prior to entering the restricted area. Transport drivers willnot be allowed to assist in unloading activities other than to operate the transport vehicle. 7.3 All personnel will be required to survey themsetves prior to leaving thesite. Survey results will be maintained at White Mesa Mill. 7.4 Transport vehicles will be surveyed for removable and fixed alpha and beta/gamma surveys prior to leaving Umetco's facility. These surveyswill be documented and retained in umetco's permanent records. Upon arrival of the waste shipment at the White Mesa Mill, the Manager of Operations or designee will inspect the shipment for conformity to the accom-pany shipping manifest and previously received documentation described in3.0. The manifest will be examined by the responsible personnel and thefollowing items will be checked for accuracy: a) b) c) d) el Manifest number. Description of waste materials shipped. Ouantity shipped and received. Conformity to manifest description of waste materials to be disposed of. ldentification of any suspicious materials, such as organics, oils, solvents, chemicals, etc. Originator and site where waste material was generated. Generator's US-NRC License Number. Appropriate signatures by all parties. Correct dates of shipping and receiving, and Notation will be made on umetco's manifest of the location of the waste material's placement within the disposal area.

The activity results will be recorded on the shipping manifest and White Mesa records. 8.3 Material suspected of not meeting the requirements set forth in US- NRC License SUA-1358 will be kept segregated from the other waste material until a determination is made of its acceptability for disposal. Suspect material will be containerized, if necessary, to avoid contami- nation of other materials. The suspect material will be returned to the transport vehicle for immediate delivery back to the generator or addi-tional laboratory tests will be performed to determine the acceptability of the suspect material. All material that is rejected for disposal will be returned to the generator within a reasonable time. The shipping mani- fest will be appropriately marked and a copy will be maintained by Umetco for documentation of items not acceptable for waste disposal. Acceptable waste material will be dumped from the transport in a safe manner to minimize dust. lf determined that dust will be generated, a water spray will be applied to the material during disposal. Care will be taken, prior to and during off loading from the transport not to saturate the material. Accepted solid waste material will be placed on the tailings surface in the designated disposal area in layers. Each layer of the waste material will be compacted with at least one pass of the construction equipment prior toplacing an additional layer. Free volumes in the waste material will be mini- mized by filling, sectioning, or crushing. Random fill or tailings will be used tofill voids in and around the waste material. A one foot (1') thick, or thicker, if required, of native soil or mine spoil or mine spoil cover will be placed over thewaste material disposal working area at the end of each shipment or work day. The fill and cover material will each be compacted with at least one pass of the construction equipment. A complete set of waste disposal records will be kept at Umetco's White Mesa Mill. Samples of the forms are located in Appendix A to this SOP.

("DUSA") receives lle.(2) byproduct material ("byproduct material") from uranium in-situ leach operations for disposal under License Condition 10.5. The following procedure applies to acceptance, handling, and disposal of byproduct material at the White Mesa Mill (the "Mill"). 2.0 Prior to Shipment of Bvproduct 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 l0 and 49 of the U.S. Code of Federal Regulations ("CFR') and the Shipper must certifu that the byproduct material does not contain hazardous waste as t defined in the Resource Conservation and Recovery Act ("RCRA"). f Information regarding the byproduct material to be disposed of should be received prior i' i to receipt of the shipment at the Mill, and shall include: li L The volume of material in cubic feet or yards, or quantity of drums and their ii size. ll 2.

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 milliremr/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 verifu, prior to receipt of any shipment of byproduct material, that the disposal of such byproduct material will not cause the Mill to exceed the limit of 5,000 cubic yards of byproduct material from a single source, set out in Mill License condition 10.5A Comtrent [RU: Does DUSA rcquire othu malyical that slrows that the byproduct material meets the RCRA requiremmts.

The following procedure applies to acceptance, handling, and disposal of byproduct material at the White Mesa Mill (the "Mill"). 2.0 Prior to Shipment of Bvproduct 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: l. 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 (mrlhr) 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 limit of 5,000 cubic yards of byproduct material from a single source, set out in Mill License condition 10.5A 3.0 Desisnated 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: C:\Users\tischler\Desktop\SOP repsonse I le2 monitor\Markup Prop I 1e2 SOPs 05.31.1 I clean.doc No.: PBL-I0 Rev.

STANDARD OPERATING PROCEDURES Title: I le.(2) Page 2 of 10 2. 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); 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; There must be at least 4 feet of tailings sands under the Designated Disposal Area; The Designated Disposal Area must be located at least 12 feet from the sides or dikes of the tailings cell; 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; 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 Secretarv DUSA shall notifu 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. 5.0 Bvproduct Material Receivins l. When each truck driver enters the restricted area for the first time, the scale house operator will provide hazard training for the driver. The driver will be provided with the Safety Training Form (Attachment 1). All drivers will be required to read the Safety Training Form and sign and date the Safety Training Form indicating that they understand and agree to follow C:\Users\tischler\Desktop\SOP repsonse I le2 monitorWlarkup Prop 1le2 SOPs 05.31.1I clean.doc J. 4. 5. 6.

DUSA's safety rules and procedures while on company property. The scale house operator will sign the Safety Training Form as the instructor for DUSA. Completed Safety Training Forms will be tumed in to the Safety Department for future reference. 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. Record the inbound date and both the truck and trailer numbers on the Scale house Weight Ticket (SWT). 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. 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 10.5.8). Bvproduct Material Unloadins 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. Radiation Safety personnel will escort the shipment to the designated location in the Designated Disposal Area for unloading of the byproduct material.

STANDARD OPERATING PROCEDURES Title: l le Page 4 of 10 a. The shipment will be transported to the Designated Disposal Area only on established roadways onto the tailings cells. b. 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 tailings sands under the Designated Disposal Area; d. The Designated Disposal Area must be located at least 12 feet from the sides or dikes of the tailings cell; 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. 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. If the shipment is determined to be acceptable, the following procedures will be followed: Ifthe 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. 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. 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. 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. 0 Beta-gamma measurements will be taken at several locations around the unloaded material.

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 ("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 verifu 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%o 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. l) Shipment and disposal activities will be documented as described in Section 10, below. 7.0 Coverins of Byproduct Material l. 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 one pass of the construction equipment prior to placing an additional layer. 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 dismantled, 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. C:\Users\jtischler\Desktop\SOP repsonse I le2 monitorMarkup Prop I le2 SOPs 05.31.1I clean.doc No.: PBL-10 Rev.

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. If the shipment is determined to be acceptable, the following procedures will be followed: If the 7-day notice has been given under Section 4.0 above and the J calendar days have lapsed, the byproduct material will then be unloaded in the designated area. [f 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. 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. 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. 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.

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 byoroduct material susoected of not meeting the requirements set forth in Section 2.0 of this SOP will be kept segresated from other waste material until a determination is made of its acceptability for disposal. g!)_After unloading, a photo of the unloaded material will be taken which is attached. to the shipping documentation for verification of shipment contents. slThe 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.
