MEMORANDUM

FROM: Dean Henderson
DATE: June 25, 2024

This staff summary on the
inspection of the 2024 Annual Seeps and Springs Monitoring event 4 June
18, 2024, at I
The 2024 Event was inspected against the following enforcement documents:
The EFRI Quality
8, 2021.
Sampling Plan for Seeps and Springs In the Vicinity of the White Mesa Uranium Mill. Revision 2. July

Summary of Inspection
EFRI informed the Division by email on June 4, 2024 with an attached letter dated June 4, 2024, that EFRI
would be sampling the seeps and springs on June 18, 2024 . The Letter from EFRI provided notice
prior to sampling as required in Section 3 of the Sampling Plan. In Section 2.1 of the Sampling Plan EFRI is
required to sample annually the seeps and springs between May 1 and July 15 each year; therefore, the June 18,
2024, sampling date meets this requirement.
On June 18. 2024 Division staff (Dean Henderson and Adam Wingate) observed the EFRI staff (Tanner
Holliday and Deen Lyman) sample Cottonwood Spring, Entrance Spring, and Ruin Spring (see photographs in
Figures 1, 2 and 3 in attachment 1 below). The Division staff split a water sample with the EFRI from Ruin
Spring.

Conclusion
Based on Division staff observation of EFRI staff performing the sampling and monitoring on June 18, 2024,
it appears that they appropriately followed the field requirements in the Permit, QAP and Sampling Plan. The
findings of this inspection and results of the analytical analysis for the Division split sample of Ruin Spring will
also be included as part of the review to complete the inspection for the Annual 2024 Seeps and Springs
Monitoring Report. A letter will be drafted notifying EFRI of the closeout of the field inspection and split
sampling for the annual 2024 seeps and springs monitoring event.
