March 27, 2017 C-1981-025/North Thompson Creek Mine CCW <br />- The embankments of the T-2 Pond were well vegetated and stable. There were no issues noted. The water <br />impounded in the pond had reached the level of the primary spillway. The spillway is a PVC pipe in the <br />embankment of the pond. The spillway was functioning as designed and was discharging water to the P9 Pond. <br />- The P9 Pond was full at the time of the inspection. The embankments were well vegetated and stable. There <br />were no indications of erosion. The level of the water in the P9 Pond had reached the level of the primary <br />spillway. The design of the primary spillway is an open ditch. The spillway was in good repair and functioning as <br />designed. <br />- The spillway from the P9 Pond directs the discharge to an open ditch leading to the Refuse Pond. This dich was <br />transporting water at the time of the inspection. The ditch is generally in good condition and is functioning as <br />designed. There are two portions of the ditch that are within the first couple hundred feet after the P9 Pond <br />that should be cleaned. These portions of the ditch have filled in with sediment and were nearing the height <br />of the edges of the ditch (Photos 3 & 4). Please clean these portions of the ditch to ensure that no water <br />overflows. <br />- The Refuse Pond was impounding water (Photo 5). The level of the water in the pond was not at the level of the <br />old primary spillway. The old primary spillway was plugged to prevent the water from discharging from the pond. <br />This was done at the landowner's request to support the post mining land use. The embankments were well <br />vegetated and stable. There were no issues noted. <br />RECLAMATION SUCCESS - Rule 4.15, Rule 3: <br />There are 4.1 acres of land at the North Thompson Creek Mines associated with the water treatment <br />system.
