Mining will develop a gravel pit to a depth of approximately 20 feet. No groundwater is <br /> expected to be encountered during excavation and mining;therefore, no impact to the <br /> hydrologic balance is anticipated. No acid or toxic producing materials will be exposed during <br /> mining. No explosives will be used in conjunction with mining or reclamation. All interior haul <br /> roads will be temporary and will be reclaimed after the mining has been completed. The ranch <br /> road connecting the property to Huerfano County Road 110 will remain following reclamation, <br /> per the landowner's request. The current haul road is approximately 20 feet wide. <br /> This is a privately owned site and does not require the State Historic Preservation Office <br /> requirements for a cultural or historic study. If the operator encounters any structure of note, <br /> the State Historic Preservation Office will be notified. <br /> 6.4.5 Exhibit E <br /> Reclamation Plan <br /> Reclamation to rangeland will occur immediately in all areas owned by Chris and <br /> Barbara Dickey with the goal of releasing this acreage from the site as rapidly as possible. <br /> Reclamation to rangeland will occur for the remaining portions of the site following mining at <br /> the site. Slopes will be returned to a 3H:1V slope or flatter when mining has concluded,thus <br /> allowing for reclamation to immediately follow mining as the site progresses. As topsoil, waste <br /> rock and overburden are removed from the working face,they will be stockpiled for future <br /> reclamation use. Throughout mining, slopes will be maintained at a 3H:1V minimum, except for <br /> the active mine face. Waste rock and overburden will be placed on the pit floor as quantity <br /> allows. Three to six inches of topsoil will be replaced on affected surfaces. If necessary, <br /> surfaces will be roughened prior to seeding. All materials used for backfilling will be generated <br /> from onsite sources. Onsite topsoil will be adequate for reclamation purposes. No importation <br /> of materials for reclamation purposes will be necessary. <br /> No trees, shrubs, or bushy-type vegetation will be planted. Only the appropriate grasses <br /> selected by the NRCS will be used. The operator will use the seed mix from the original permit <br /> application below. The seed will be broadcast at the rates below. <br /> Page 6 of 21 <br />
