• INTRODUCTION <br />Sediment Pond 008 is proposed to be constructed in the Bond Creek drainage <br />which is tributary to Fish Creek. Pond 008 will contain runoff from areas <br />currently draining into Pond 007, which is scheduled to be mined through <br />in early 1988, in addition to runoff from areas mined in 1988 and 1989 <br />(see Exhibit 12-1, Operations Pian). Pond 008 is designed to handle <br />runoff from its entire watershed. This pond is located in the SW~ of the <br />NW}; Sec. 7; T5N; R86W (see Exhibit 7-7). <br />SITE DESCRIPTION <br />Land Use <br />Sediment Pond 008 has a 247-acre watershed which is tributary to Fish <br />Creek. The watershed is classified as a mixture of undisturbed, <br />disturbed, and reclaimed areas as broken down in Table 7-6e-4. <br />• Embankment <br />The proposed embankment for Pond 008 will be a homogeneous earth fill <br />compacted in lifts to design specifications. The top width of the <br />embankment will be approximately 15 feet wide with upstream and downstream <br />slopes of approximately 3h:ly each. The principal spillway will be a <br />6-inch diameter orifice cut into a 24-inch diameter drop inlet pipe. The <br />emergency spillway will be the 24-inch diameter drop inlet CMP. <br />DESIGN ANALYSIS <br />General <br />Sediment Pond 008 was designed to meet or exceed the design and <br />performance requirements of the Colorado Mined Land Reclamation Division. <br /> <br />7-6e-1 <br />
