Deficiencies: ISL documentation is incomplete it does not completely document disposal activities and steps taken to minimize void spaces. In discussing this observation with the Mills RSO, the Inspector was provided a new form that will be filled out for ISL (11 e(2)) material disposal. This form is Attachment 2 lie.(2) Byproduct Material Disposal Documentation Form and it part of SOP PBL-10 R-3 lie. (2) Byproduct ^ Disposal. This revision of the procedure is currently be reviewed by the DRC and won't be implemented until the DRC approves the procedure. Closeout Meeting Denison Mines: Dave Turk (RSO) Ronnie Nieves (Radiological Coordinator) Utah DRC: Ryan Johnson (Inspector) Kevin Camey (Inspector) During the closeout meeting the inspector discussed with RSO the number of air particulate monitoring stations around the Mill. The inspector questioned, due to the size of the Mill property, if there were enough BHV stations around the Mill to properly document the effluents fi'om the Mill's ore pad, stacks and tailings cells. Findings The following fmdings were observed during this inspection: 1. Large cracks were observed in the concrete floor of the Altemate Feed Circuit area; 2. Dmms being staged to be put into the Altemate Feed Circuit were being placed on soil; and 3. Incomplete documentation ofthe 1 le.(2) material disposal process. The Inspector also observed that the White Mesa Mill was in the process of correcting all ofthe findings observed at the time of the inspection. Therefore, no enforcement actions will be taken and these findings will be followed up by the DRC during the next inspection. Recommendations The following are DRC recommendations regarding items for improvement: 1. The DRC recommends that the 11 e.(2) Byproduct Material Disposal Documentation Form in Attachment 2 of SOP PBL-10 R-3 1 le.(2) Byproduct Disposal is used immediately and not to wait for DRC approval of the SOP. 2. The DRC recommends that the concrete for the Dmm Dumping Node is completed. 3. The DRC recommends that the cracks in the concrete floor of the Altemate Feed Circuit are repaired. 3 of Page 4 U:\rad\COMMON\Uranium millsM le(2)UT 1900479 Denison Mines - White Mesa UMill\HP hispection modules\201 I\hispection ReportsVhispection Report RADMOD-AFIL^Ol 9-22-11 RJ.doc UTAH DIVISION OF RADIATION CONTROL Inspecdon Module RADMOD-AFIL WHITE MESA MILL RML LICENSE UTI900479 OPENING MEETING INSPECTOR(S) /C DATE f-^<^-//^ MEETESIG MEMBERS NAME COMPANY CONTACT ESIFORMATION UTAH DIVISION OF RADIATION CONTROL DISCUSSION //^ .

Yes or No Inspection Summarv The inspection consisted of employee interviews, review of documentation and a mill tour. The following discussion provides more detail of the specific items. Item 1. Mill Tour: The inspector walked through the restricted area on a general site tour. The tour included the ore pad, the new decontamination pad, the mill, the altemate feed circuit, and the tailings ponds. No ISL material was being disposed during the inspection and those activities were not observed. ^ Observations: The DRC inspector observed: • Proper PPE was being worn by Mill employees within the Altemate Feed Circuit and other areas of the Mill; • Proper Radiological Posting were being used at the Altemate Feed Circuit; • TLDs were appropriately being used for general area Gamma radiation monitoring within the Altemate Feed Circuit; and • Appropriate air monitoring, both general area and quarterly breathing zone, was being done within the Altemate feed circuit. Deficiencies: The inspector observed the following deficiencies: • Large cracks in the cement floor in the Altemate Feed Circuit area; and • Dmms that were being "staged" next to the Dmm Dumping Node of the Altemate Feed Circuit. The Inspector did observe that repair activities were being done on the cracks in the floor and the RSO said that concrete will be poured by October 15, 2011 in the area where the dmms are being staged. Item 2. Documentation: Alternate Feed Documentation: The Inspector reviewed the documentation for altemate feed acceptance. Observations: The altemate feed documentation documented: • The date of the shipment; • The generators name; • The amount of material that was in each shipment; and • Where the altemate feed material was being stored. ISL Disposal Documentation: The Inspector reviewed the documentation for ISL acceptance and disposal. Observations: The ISL material shipment was documented with: • A Bill of Lading; • Photographs of the load of material when it arrived; • PID (VOC) readings; • Radiological Survey Information fi'om the load when it arrived; and 2 of Page 4 U:\rad\C0MM0N\Uranium millsM le(2)UTl900479 Denison Mines - White Mesa UMilI\HP hispection modules\201 l\hispection Reports\hispectionReportRADMOD-AFIL-019-22-llRJ.doc • The generators shipping papers. Deficiencies: ISL documentation is incomplete it does not completely document disposal activities and steps taken to minimize void spaces. In discussing this observation with the Mills RSO, the Inspector was provided a new form that will be filled out for ISL (11 e(2)) material disposal. This form is Attachment 2 lie. (2) Byproduct' Material Disposal Documentation Form and it part of SOP PBL-10 R-3 lie. (2) Byproduct Disposal. This revision of the procedure is currently be reviewed by the DRC and won't be implemented until the DRC approves the procedure. Closeout Meeting Denison Mines: Dave Turk (RSO) Ronnie Nieves (Radiological Coordinator) Utah DRC: Ryan Johnson (Inspector) Kevin Camey (Inspector) During the closeout meeting the inspector discussed with RSO the number of air particulate monitoring stations around the Mill. The inspector questioned, due to the size of the Mill property, if there were enough BHV stations around the Mill to properly document the effluents fi^om the Mill's ore pad, stacks and tailings cells. Findings The following findings were observed during this inspection: 1. Large cracks were observed in the concrete floor of the Altemate Feed Circuit area; 2. Dmms being staged to be put into the Altemate Feed Circuit were being placed on spil; and 3. Incomplete documentation of the 1 le.(2) material disposal process. The Inspector also observed that the White Mesa Mill was in the process of correcting all of the findings observed at the time of the inspection. Therefore, no enforcement actions will be taken and these fmdings will be followed up by the DRC during the next inspection. Recommendations The following are DRC recommendations regarding items for improvement: 1. The DRC recommends that the 11 e.(2) Byproduct Material Disposal Documentation Form in Attachment 2 of SOP PBL-10 R-3 1 le.(2) Byproduct Disposal is used immediately and not to wait for DRC approval of the SOP. 2.
