~, has been inspected by the Teller County Commissioners and the County <br />~~ Road Superintendent and approval for the relocation has been obtained. <br />The road will be built to the specifications set by the County Road <br />Superintendent. A berm will be constructed on the north side of the <br />road to contain any drainage from the waste dump area. Any drainage <br />wd~t1 be directed tp a sediment settling pond prior to discharge into <br />Four Mile Creek. <br />Topsoil from the area to be covered by the waste dump <br />expansion will be salvaged, stockpiled and seeded for use in recla- <br />mation of the area. <br />Reclamation of this area will consist of reducing the <br />slopes•of the waste dump to a non-hazardous stable slope, replacing <br />topsoil and reseeding the top of the dump as suggested by MLRB personnel. <br />It will be necessary to remove the buildup of rock and <br />J sediment from the ditch in the tunnel. This will create an increase <br />`~- in suspended solids being discharged from the portal. It is planned <br />to construct a series of settling ponds on the existing waste dump <br />to settle these suspended solids prior to discharge into Four M11e Creek. <br />These settling ponds will occupy an area 450'X60' and 5:d:^~~2 <br />will be constructed to allow bypassing the flow to the final pond ~~c "'A1`'~n` P <br />to allow cleaning of the three upstream ponds of sediment. ~l~ <br />Run off from the drainage basin is calculated for the <br />100 year flood at 36 CF5 fora 5 minute peak flow. This will be <br />bypassed over the culvert controlling the discharge from the tunnel <br />through a 36" culvert to avoid mingling of the drainage with the <br />discharge water in the ponds. The drainage from the smaller drains <br />west of the portal will be controlled by berms to avoid flow into the ponds. <br />-d Uh4381 <br />
