ea) Trickle tube is used in Sedcad Model to simulate pond water depth of 0' at the time of the event. Pond shall be dewatered via conventional means; pumped or siphoned following any storm which raises the pond level to the point that a 10 year event can not be stored. 8b) The RP-SA undisturbed area diversion ditch will see a maximum flow of 49.0 c.f.s. at the design capacity. The design criteria is as follows: Design Max. Allow. Actual Velocity Spacing Peak Slope °s Slope °s Control 49 cfs 0.7°s 3% Check Dam 40' A Sedcad printout of these calculations is included. The typical undisturbed ditch design is on Map 80A. 8c) A copy of this table is included. 8d) A revised table and applicable Sedcad calculations are included. 9) The USDA/SCS publication, Soil Survev of Rio Blanco County Area. Colorado does list the Moyerson soil type as having severe limitations as a pond or reservoir area, assuming that the pond is built on that area. The proposed pond is to be constructed in the Turley soil group and then lined with Moyerson soil. Test pits in the Turley show it to be more than eight feet deep in the general vicinity of the pond. Engineering data from the SCS publication classifies the Moyerson group as CL,CH under the unified soil classification system. In addition, the soil is shown to have on average 0 to 15 percent particles greater than 3 inches and that 95 percent passes a #4 sieve. CL and CH soil types range from poor permeability to practically impervious (USDI Bureau of reclamation, "Design of Small Dams," U.S. Government Printing Office, 1987, p. 98) This classification and the observed local soil characteristics should allow the Moyerson to be a suitable pond liner. 14) From past experience winter storage of refuse material has occurred between the months of Nov. and April. With monthly refuse material production of 37,000 tons for a total winter storage of 222,000 tons. This material will be stored on the permitted temporary storage areas and on the refuse areas. During the Spring, as late as May, this material will begin to be spread and compacted. The volume of the refuse to be stored is 113 acre feet. Normal refuse storage shall be in piles 5 to 10 feet in height. Assuming 5' high piles a total of 23 acres will be needed for winter storage which will leave 34 acres of pit available for a working area.
