On August 13, 2015 during routine biweekly water sampling of Cameco Resources, Crow Butte Operation (CBO) shallow monitor well SM6-24, exceeded the multiple parameter upper control limit (MCL) for conductivity and alkalinity. As required by License Condition 11.5 of Source Materials License SUA-1534, a second sample was collected from SM6-24 within 48 hours and analyzed for the three excursion indicator parameters. The results of the second sample also exceeded the excursion control parameters as described above.
CBO notified Mr. Ron Burrows of the excursion by at 10:30 a.m. on August 14, 2015 as required in License Conditions 11.5 and 11.6. Laboratory results for the sample analysis for SM6-24 are attached. In addition, graphs are attached for the three excursion indicator parameters and water levels that cover the period from December 4, 2014, to August 14, 2015.
