-g- 1. The two proposed permanent ponds are located approximately 1/4 mile apart. According to SCS Public Standard 378, "livestock water within a pasture bounded by fences or a natural livestock barrier generally should not be closer together than a travel distance of three-eighths to three-fourths mile in foothills or rolling land.° During dry seasons, when tt is proposed to use these ponds, Middle Creek will not be flowing and, therefore, will not present a natural barrier. Additionally, to Section 2.05.5, it 15 stated that "CYCC will avoid fencing wherever possible." Before the Division will allow two permanent ponds so close together, CYCC must address the pasture boundaries in view of the above concerns. 2. Before a reasonable assessment of the effects of the permanent ponds can be made, the Division needs maps at a sufficient scale detailing construction of these ponds. The maps should include inside contours of the pond, bottom elevation of the pond, ditch inflow points, spillway and embankment details, and pond location with respect to Middle Creek. 3. The fact that these ponds are proposed permanent ponds should be discussed 1n the permit application itself, and not ,Just to Exhibit 3. 4. The 10-year, 24-hour storm must be contained in the ponds. If high inflows result in water levels above the level required to allow adequate storage of this storm, provisions must be made in the permit application to dewater the ponds to the necessary level. 5. On page 2.05-162, tt 15 stated that the detention basins will be monitored at inlet and outlet. Will each inlet be monitored? 6. If the Mine No. 3 detention pond is proposed as a permanent pond according to the deta7ls in Addendum 1, the following additional information 1s necessary. a. It 1s proposed to fill this pond with 100,000 yd3 of overburden material. Where will this material come from? It 15 not accounted for on the Spoil Grading Plan, Map No. 10. Based upon the present reclamation plan, 1t does not appear that there is 100,000 yd3 additional material available for placement in the pond. b. If 100,000 yd3 1s available, how will the filling be accomplished? W111 it be dumped artd compacted? Where will the access road to accomplish this be located? W711 the material be spread evenly throughout the pond, or will certain areas be filled 1n to reduce the pond surface area? c. When will this filling be accomplished? What provisions will be made tf there is a significant amount of water in the pond at the proposed time of filling?
