RE: Source Material License SUA-56; Western Nuclear, Inc., Split Rock Uranium Mill Tailings Facility;Surface Water and Groundwater Monitoring Report

Dear Deputy Director:

Please find enclosed for Nuclear Regulatory Commission review, the surface water and groundwater samplingresults for the second half of 2008 for the Split Rock Uranium mill tailings facility. This monitoring was performed asrequired by license conditions 24 and 74.

Figure 1 shows the location of the monitor wells and the surface water sample locations. The table presents theanalytical results. Figures are also included in the enclosure, which show the temporal changes in water quality forkey constituents. Some of the wells have more historic data as they were part of the previous monitoring network.The remaining wells have limited historic data since they were only sampled as part of the characterization study.

As previously coordinated with NRC staff, monitor well maintenance has been recently performed due to sanding upof two existing monitor wells such that they drew insufficient water to provide a valid sample volume. Monitor wellsSWAB-1 and SWAB-1 2 were replaced by monitor wells SWAB-1 R and SWAB-1 2R, respectively. Water quality inSWAB-12R shows similar water quality to the previous values and has concentrations that are indicative ofbackground water quality.

Water quality data from the replacement well SWAB-1 R shows higher concentrations for some constituents, notablyuranium and sulfate, than previous data measured from well SWAB-1. SWAB-1 has shown elevated levels ofconstituents indicative of tailings seepage and is in the groundwater plume. It is thought that the higher values inSWAB-1 R are a result of higher concentrations of tailings derived constituents at a slightly deeper depth in SWAB-1 Rthan were encountered in well SWAB-1 which was completed at a more shallow depth. The characterization datapreviously submitted indicates that there are variations in concentrations within the contaminate plume at differentdepths. While the data from SWAB-1 R has higher concentrations for uranium and sulfate, these values areconsistent with SWAB-2 which is nearby and up-gradient. Water quality data from SWAB-2 has remained constant.The next down-gradient well, SWAB-29 shows no change in concentrations and has values that are indicative of

Deputy Director, NRC of 2August 17, 2009

background water quality. Therefore, while some of the water quality values from SWAB-1 R are greater than valuesfrom SWAB-i, it is believed they are reflective of expected variations in water quality with depth and not indicative ofchanging site conditions.

In all cases, including the new data from the replacement wells, the data indicate that surface water and groundwaterquality are within expected ranges and that the system is behaving as predicted.

If you have any questions, please contact me at your convenience.

Sin ly,

Louis MillerConsulting Engineer
