INSPECTION REPORT
Inspection Module: RADMOD-RPP: Respiratory Protection Program (RPP) Inspection Location: Energy Fuels - White Mesa Uranium Mill, Blanding Utah.
Inspection Items: Respiratory Protection
Inspection Dates: February 13 & 14, 2023 Inspectors: Ryan Johnson, Utah Division Waste Management and Radiation Control
(DWMRC)
Personnel Contacted: Garrin Palmer, Radiation Safety Officer (RS0) Justin Perkins, Radiation Safety Technician (RST)
Governing Documents:

Item 1. Documentation Review: The Inspector reviewed applicable documentation.
Observations: The DWMRC inspectors reviewed the following documents:
• The current Respiratory Protection Manual and confirmed all required respirator protection procedures from R313-15-703 and NRC Reg. Guide 8.15 are covered in the manual;
• The respirator issuance log;
• Respirator Damage Sheet;
• Fit testing and respirator training documentation;
• Respirator survey forms; and
• The Medical Clearance form. Deficiencies: None
Item 2. Mill Tour: The Inspectors walked through the restricted area on a general site tour. The
tour included ore pad, the mill, the solvent extraction building, the alternate feed circuit, the tailing impoundments, and the respirator room. Observations: The DWMRC inspectors also observed:
• OSL badges were appropriately being used by all observed employees at the Mill;
• Native ore and Alternate feeds are being stored on the ore pad. All of the Chemours ore that has been at the Mill is being processed.
• Respirator room was clean and well organized;
• Respirators were clean and in good repair; and
• Meters used to survey respirators were calibrated and in good repair.
The Inspectors spoke with the Safety Technician that performs the fit testing at the Mill. The Mill is using the same equipment and procedures as they have in previous years. Radiological readings observed during Mill tour Location Dose Rate (µrem/hr)
Mill 200-500
Tank #7 2,000
Packaging Room 200 Solvent Extraction Building 50
Ore Pad 50-1,000
Silmet 3,000-4,000 Respirator room 40
Deficiencies: None

Item 3. Other:
Observations: Tailing Impoundment 4B
The Mill has been working on filling the 40 acre tailing impoundment. At the Time of the inspection the Inspector estimated that water covers about 80% of the floor of the 4B.
Deficiencies: The inspector observed that EFRI has not put a minimum of 1 foot of liquid across the bottom of 4B. However, this issue is regulated by the Utah Division of Air Quality, not the DWMRC.
Observations: Solvent Extraction Building The Mill is preparing the south end of the solvent extraction building to be used for the solvent extraction of rare earth elements (REE). The Mill has already removed the old equipment that was
in that part of the building. During the close out meeting the Inspector recommended that the RSO and the RSTs do a radiological survey of that area to verify that there is no residual contamination in the area before construction of the REE solvent extraction circuit. Closeout Meeting
Energy Fuels: Garrin Palmer, RSO Logan Shumway, Mill Manager Terry Slade, RST
Utah DWMRC: Ryan Johnson (Health Physics Inspector) Findings
None Recommendations None
Recommendation for Next Inspection Continued observation of tailing impoundment 4B
