continued to have reported uranium values that exceeded their respective
target action limits The two monitor wells are being sampled monthly for
uranium analysis

RIO ALGOM MINING LLC-LISBON OPERATION
Semiannual Groundwater Monitoring Report
2nd Half 2011

Introduction:

This report meets the requirements of DRC License # UT 1900481, Condition 53, and presents
the monitoring results of the groundwater sampling required by the Long Term Surveillance
Monitoring Plan (LTSP). This report contains the following elements:

A discussion and interpretation of the groundwater sampling results and concentration
trends, Uranium Compliance limits or Uranium Target Action levels as stated in table 1,
license condition 53 B.

Appendix 1 contains analytical data, time versus concentration plots, depth to water with
time, and hydrographs for each of the monitoring wells.

Appendix 2 presents the field data sheets including the field parameter measurements.

Appendix 3 presents copies of the laboratory analytical reports for the 2nd half of 2011.

Appendix 4 presents the groundwater contour maps.

Appendix 5 contains the sampling methodologies used to conduct the sampling.

Discussion

The data provided in this report represent sampling results from the 2nd half of 2011.

The required monitoring wells are listed below:

Table 1

Monitoring Well Network

Well Identification (s) Purpose
EF-3A, OWUT-9 POC wells (Point of Compliance)
MW-13, MW-5 Monitor background water quality
RL-4, RL-5, RL-6 POE wells (Point of Exposure)
EF-6, EF-8, ML-1, RL-1, RL-3, H-63,
LW-1 Trend wells

The Alternate Concentration Limits (ACLs) granted by the USNRC and accepted by the State of
Utah that apply to wells EF-3A and OWUT-9 are presented below.

In granting ACLs for the Lisbon Site the USNRC maintained the Background groundwater
concentrations at the same level established in 1990 and they are as follows:

Reviewing the results from the current sampling event for background wells MW-13 and MW-5,
the following concentrations were noted.

Table 5

Background Well MW-13 and MW-5 Results

U-Nat mg/L As mg/L Mo mg/L Se mg/L
MW-13 0.014 0.029 0.01 0.008
MW-5 0.008 < 0.001 <0.01 0.043

All of the above reported concentrations, with the exception of Se in MW-5, are below the
background concentrations. Review of the trending of the selenium concentration in MW-5
shows a steady concentration of approximately 0.06 mg/L since February 2002.

Wells RL-4, RL-5, and RL-6, located on the northern Long Term Surveillance and Monitoring
(LTSM) boundary, are used for monitoring Point of Exposure (POE) concentrations. The
constituent of concern (COC) for the POE wells, as stated in Table 2 of license condition 53 B, is
U-Nat and the Uranium Compliance Limit is 0.32 mg/L. Table 6 presents the observed U-Nat
concentration for the second half of 2011 versus the Uranium Compliance Limit. All of the POE
wells are well below the 0.32 mg/L health based standard.

Trend wells EF-6, EF- 8, ML-1, RL-1, RL-3, H-63 and LW-1, located throughout the area to be
transferred to the Department of Energy, are used for validation of the transport model prediction

and trends. The constituent of concern for these wells is U-Nat as stated in Table 3 of license
condition 53 B. Table No. 7 shows the comparison of the concentration found in these trend wells
with the Uranium Target Action Levels. All uranium concentrations within these wells were below
the target action level established within the license except RL-1 and EF-8.

Table 7

Uranium Concentrations – Trend Wells

The results shown for Monitor Well RL-1 for the months of August, October, November, and
December represent the average of duplicate samples taken on the date indicated. The uranium
results shown for Monitor Well EF-8 taken on October 19, 2011 represent the average of two
duplicate samples. There were no definite trends observed in the uranium values obtained for
Monitor Wells RL-1 and EF-8. The uranium values shown in Table 7 for Monitor Wells RL-1 and
EF-8 exceed their respective Uranium Target Action Levels. As per License Condition 53 C.,
both of these monitor wells have an Out-of-Compliance, OOC, status

Monitor Well EF-8 obtained the status of Probable-out-of-Compliance, POOC, during the first half
of 2011. Monitor Well EF-8 obtained the status of Out-of-Compliance when the uranium result
obtained during the August 2011 sampling event, 0.3289 mg/L, exceeded the Uranium Target
Action Level of 0.30 mg/L. Rio Algom Mining LLC, RAML, provided Notice of the OOC status in
a letter sent to the Division of Radiation Control Director on September 21, 2011.

Four personnel from the Utah Department of Radiation Control (UDRC) observed RAML’s
procedure for Low-Flow Sampling on October 19, 2011. The monitor wells sampled during
the observation were MW EF-3A and MW EF-8; split samples were taken by UDRC
personnel during the sampling of the two wells.

RAML is currently addressing the comments provided by the UDRC (letter to RAML dated
February 6, 2012) on the RAML “Supplemental Site Assessment to Address Out-of-
Compliance Status at Trend Wells RL-1 and EF-8, Lisbon Facility,” dated December 13,
2011. A revised work plan is currently being drafted and will be submitted for UDRC review
and approval prior to field activities.
