Technical Revision <br />page 4 <br />• Highway 133 and discharge through a 1/2 culvert energy dissipator <br /> into the North Fork of the Gunnison River. The westerly <br />diversion will flow through a diversion ditch into a culvert <br />under Colorado 133, through a 1/2 culvert to the railroad tracks, <br />under the railroad tracks in a culvert and dissipate through <br />a I/2 culvert discharging into the river. The 30 inch culvert <br />from the gulch has been covered ir. great detail during previous <br />discussions. <br />Areas 1 and lA drain along the north side of the highway, <br />through a culvert at the west end of the parking lot, then <br />through a diversion ditch into the West Mine (USS) pond. Area <br />2 drains through the same diversion ditch on the west and another <br />• on the east (between areas 2 and 4A) into the West Mine (USS) <br />And. <br />Areas 2A, 4A, 3 and 9 drain via a diversion ditch north of the <br />railroad tracks to a culvert feeding the Sediment Pond (Norris). <br />Areas delineated (1, lA, 2, etc.) are discussed in detail in <br />the sediment calculations of l~hibit T mentioned above. <br />Water discharging through culverts will be dissipated with <br />1/2 culverts in those instances described above. Other culverts <br />indicated on the map will have rock lining the ditch immediately <br />• below the culvert. <br />
