This is a Utah Division of Waste Management and Radiation Control ("Division") staff summary on the
field inspection and split sampling of the 4th Quarter 2023 groundwater monitoring event ("Monitoring
Event") performed on November 6, 7, and 8, 2023, for the Energy Fuels Resources (USA), Inc.
("EFRI") White Mesa Uranium Mill, near Blanding, Utah. EFRI is required to submit a written
groundwater monitoring report of this monitoring event by March 1, 2024. The monitoring event was
inspected against the following enforcement documents:
• White Mesa Uranium Mill Ground Water Quality Assurance Plan ("QAP").
Revision 7.6, dated August 8, 2019.
Summary of Inspection
November 6, 7, and 8, 2023, Division staff Dean Henderson, Phil Goble and Chris Leahy observed the
EFRI staff preform groundwater monitoring activities including the collection of ground water samples
from monitor wells for the tailings cell groundwater monitoring network. In addition, the Division staff
collected a split sample from monitor wells MW-14, MW-25, MW-27, MW-31, MW-32, MW-35, MW-
36, and MW-41B. A duplicate sample was collected at well MW-32 and is identified as MW-80. See
the photographs of sampling activities in figures 1 and 2 in Attachment 1 below.
After the monitoring event was completed, a close out meeting was held with the following attendees:
Division staff Dean Henderson, Phil Goble, Chris Leahy and EFRI staff Tanner Holliday, Garrin Palmer
Logan Shumway, and Terry Slade. In the meeting the Division staff told the EFRI staff that they
appeared to follow the QAP.

November 6, 7, and 8, 2023, it appears that EFRI appropriately followed the field requirements in the
QAP. As stated above, EFRI is required to submit a written report of this Monitoring Event on March 1,
2024. The Division will also review this report and will include split sample analysis for this monitoring
event as part of that review to complete the inspection of the 4th Quarter 2023 groundwater monitoring
