2012 Annual Tailings Cells, Leak Detection Systems and Shmes Drains Waste Water
Sampling and Utah Division of Radiation Split samplmg
Energy Fuels Resources (USA), Inc White Mesa Uranium Mill, near Blanding, Utah
On August 15, 2012 the Utah Division of Radiation Control (hereafter "DRC") staff Dean Henderson
observed Energy Fuels Resources (USA), Inc (hereafter "EFR") staff Tanner Holiday and Gamn Palmer
perform the momtonng and sampling for the 2012 annual tailings cells, leak detection systems and slimes
drains waste water sampling event
The DRC collected a split waste water sample from tailing Cell 4B A duplicate sample of tailing Cell 4B
was also collected and is identified as Cell 6 On August 16, 2012 both samples were shipped to Lionville
Laboratory by UPS in two coolers One cooler was shipped next day air that earned portions of the
samples m containers packed in ice to be analyzed for the non-radiologics listed m Table 1 of Section 8 2
of EFR Ground Water Monitonng Quality Assurance Plan (hereafter "QAP") and SVOC as required in
Part 1 E 2(ii) of EFR Ground Water Discharge Permit The other cooler was shipped by ground that had
portions ofthe samples in containers to be analyzed for gross alpha A report on DRC sample results and
companson with EFR sample results will be completed after the 2012 Aimual Tailings Wastewater
Monitonng Report is submitted to DRC on December 1, 2012
The DRC staff also observed the EFR staff collect waste water samples from tailing Cell 1 (see Figures 1
and 2), Cell 2 shmes drain (see Figure 3), Cell 3 (see Figure 4), Cell 4A, Cell 4A leak detection system
(thereafter "LDS"), Cell 4B, and Cell 4B LDS The LDS monitors for Cell 1, Cell 2, and Cell 3 had fluid
level measurements of 0 0 feet therefore, no samples were collected Samples for Cell 1, Cell 3, Cell 4A,
Cell 4A LDS, Cell 4B, and Cell 4B LDS were collected with the use ofa disposable ladle (see Figures 1
and 2) The sample for Cell 2 slimes drain was collected using a disposable bailer (see Figure 3) Tailing
Cells 1,3,4A, and 4B LDS pumps were all able to be manually tumed on to demonstrate that the pumps
were operational
After observing the EFR staff perform the samplmg and monitonng it appears they appropnately followed
QAP and Samplmg and Analysis Plan for Tailings Cells, Leak Detection Systems and Shmes Drain A
closeout meeting was held with Mr Dan Hillsten following the completion of sampling activities Mr
Hillsten was told the sampling acti-vities appeared to go smoothly with no problems
