The mill is owned and operated by Energy Fuels Resources (the Licensee). This inspection was specific to the Licensee’s Standard Operating Procedures, Discharge Minimization Plan (DMP), dated December 2016, and Tailings Management System (TMS), dated March 2017, for the time period since the previous inspection last performed by Russ Topham on April 27, 2016. The Licensee provided copies of the current revision of the field report forms used to perform the daily, 2017 Annual BAT/DMT Inspection October 19, 2017 Page 2 2017 Annual BAT/DMT Inspection October 19,2017 Page 3 weekly, and annual inspections for the DMP and the daily, weekly, monthly and quarterly inspections for the TMS. Mr. Garrin Palmer and Mr. Tanner Holiday conducted the daily and weekly inspections of the DMP and the TMS. The monthly inspection for the TMS was also executed. As the quarterly inspection for the TMS is a summary of the quarter’s activities and overall status of the tailings cells, this inspection was not performed during this visit. The annual inspection for the decontamination pad and the ammonium sulfate cover area for the DMP had been completed previously in the 2nd Quarter of 2017, as required. All of the individual inspections components of the inspection are not reviewed in this narrative. However, the inspection forms are attached to this memo for the record. During the collection of the data, I agreed with the data collected and the staffs evaluation of the status of the Mill’s components. The Licensee’s staff demonstrated an appropriate understanding the data collected and its further use. Specific components of the onsite inspection are discussed further. • The diversion ditches and berm were visited in their entirety. The vegetation growing in the diversion ditches (1, 2, and 3) had recently been removed (Photos 1, 2, and 3) as requested during a previously inspection performed by Division staff the week of September 25, 2017. The ditches are clear of vegetation and direct rain water away from the plant. • Cells 2 and 4B were visited to review the repairs made to the embankments (Photos 4, 5, and 6). Erosion from 2017 rainfall events created rills in the embankments. Additional erosional resistivity was achieved by placing road base material over the original cover (Photo 5). • Pictures showing the methods used by Mill staff to measure the liquid elevation in Cells 1 and 4B are shown in Photos 7 and 8. • The monthly inspection form for TMS includes Section 4 - Overspray Dust Minimization. The overspray system is no longer installed at the site. It was recommended to the Licensee’s staff that this section be removed with the forms next revision. A records review of the data collected since the last inspection was performed following the site inspection. The records showed similar conditions for the previous months. Quarterly inspections performed for the previous year were reviewed for the TMS. The Annual UsedAVaste Oil and Fuel Tank Inspection forms in the DMP were also reviewed. In addition to appropriate data collection techniques and site evaluation, the records review demonstrated ongoing maintenance to protect human health and the environment. For example, Division Staff observed that when cracks in the concrete pad for the Used/Waste Oil and Fuel Tanks were identified, the cracks were filled to prevent contamination of the sediments below. Other examples of maintenance activities were: repair of the acid tank containment berm, removal and replacement of soil contaminated with hydraulic oil, clearing of ditches of vegetation, and weed clearing throughout the mill site. A close out meeting to discuss observations from the inspection included with Heather Mickelson; Phil Goble; Logan Shumway, Plant Manager; David Turk, Site Radiation Safety Officer; Garrin Palmer and Tanner Holiday. Conclusions and Recommendations The Licensee appears fully compliant with applicable laws, standards, requirements with respect to DMT/BAT data collection and evaluation. The Licensee’s personnel appear to understand the significance of the data being collected and provide accurate and comprehensive records. In addition, the correct forms, updated in 2017, are being used to record the data. No new recommendations were identified during this inspection. 2017 Annual BAT/DMT Inspection October 19, 2017 Page 4 Attachments: 2017 Annual BAT/DMT Inspection Photolog Discharge Minimization Plan Inspection Forms dated December 2016 Tailings Management System Forms dated March 2017 Photo 2.
