June 7,2011 C-1981-025/North Thompson Creek Mine J R S HYDROLOGIC BALANCE (cont.) -Treatment Ponds T-1 and T-2 were well vegetated and stable at the time of the inspection. Treatment Pond T-1 flows into Treatment Pond T-2,which then is the discharge point for the water. Currently all of the water is discharged to permanent sediment ponds P-9 and the Refuse Pile Pond. The treatment pond system(consisting of the Long Pond and Treatment Ponds T-1 and T-2)appears to be working as there is no staining of the rocks and soil at the discharge point from T-2. None of the water was discharging into the North Thompson Creek at the time of the inspection. -The operator has the water rights for all of the water flowing from the#1 and#3 mines and uses them as a developed water resource. Although sediment pond P-9 and the Refuse Pile Pond are no longer a part of the North Thompson Creek Permit,the Division did look at these ponds to make sure they were stable and had adequate capacity to hold the flow from Treatment Pond T-2. Both of these ponds appeared to be stable and both ponds had adequate capacity to hold the discharge from Treatment Pond T-2.
