Increase the height of the existing berm at the toe of the development rock area if it is less than 1.5 feet • <br />high. Make sure that the berm is at least 1.5 feet high and connect any breached areas along the berm. <br />Construct a 40 foot wide, 150 foot long, and 4 foot deep catchment basin having 1.5:1 bank slope at the <br />northwest end of the development rock area. The existing berm should be extended to capture runoff <br />from the development rock area and route it to the basin. <br />Construct a 30 foot wide, 100 foot long, and 4 foot deep catchment basin having 1.5:1 bank slope at the <br />northeast end of the development rock area. The existing berm should be extended to capture runoff <br />from the development rock area and route it to the basin. <br />Carnation <br />• Increase the height of the existing berm at the top of the development rock area, where it is less than 1.5 <br />feet high, to 1.5 feet and connect any breached areas along the berm. <br />• Maintain the existing sediment pond area and increase the depth to 3.5 feet. <br />Sunday <br />• Construct a 3.5 foot deep channel above (south) of the mine site to divert off site flows around the site. <br />Reseed the channel in the fall. <br />• Increase the height of the existing berms where they are less than 1.5 feet high, to 1.5 feet and connect <br />any breached areas along the berm. The existing berms should be extended to enclose any runoff form <br />the southeast portion of the surface facilities. <br />• Construct a 45 foot wide, 150 foot long, and 5 foot deep catchment basin having 1.5:1 bank slope at the <br />northeast end of the surface facilities (toe of the development rock area). <br />• Construct a 60 foot wide, 400 foot long, and 4.5 foot deep catchment basin having 1.5:1 bank slope a <br />the northeast end of the development rock area. • <br />Work was completed at the Sunday Complex in September of 2008. The following Drainage repair summary <br />provides a list of work completed by Sutherlands Excavation as provided by Danny Flannery of Denison Mines <br />(USA) Corp. Unfortunately no seeding occurred at the Sunday Complex in the fall of 2008. <br />Topaz Mine <br />• Off site drainage ditch above mine site was cleaned out and brought to a depth of 2.5 to 4 ft. <br />West Sunday <br />• Off site drainage above mine was cleaned and brought to a depth of at least 2.5 ft. <br />• The existing berms located at the bottom of the development rock pile were repaired where needed and <br />brought to a height of at least 1.5 feet. <br />• The catch basin at the toe of the development rock pile was repaired and improved to more than 40 feet <br />wide by 170 feet long. The basin is now at least 5feet deep. <br />• The area of the berm located around the bottom of the development rock on the East side was extended <br />and strengthened and an additional basin was constructed to ensure that any runoff from the pile would <br />be contained onsite. <br />(• <br />OENISONI)„ <br />MINES <br />2
