There will be no storage of fuel or lubricants onsite. Fuel will be hauled onsite as <br /> needed by vendor trucks. <br /> 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 of the site will be of two types, residential and rangeland. Reclamation to <br /> residential will occur first on the southern-most 7.0-acre portion of the site. Reclamation back <br /> to rangeland will occur for the remaining portions of the site. The land has historically been <br /> rangeland and is located within an HOA and will be returned to such uses following mining <br /> operations. <br /> 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 inches of topsoil will be replaced on affected surfaces. If necessary, surfaces will <br /> be roughened prior to seeding. All materials used for backfilling will be generated from onsite <br /> sources. Onsite topsoil will be adequate for reclamation purposes. No importation of materials <br /> for reclamation purposes will be necessary. <br /> No trees, shrubs, or bushy-type vegetation will be planted in the rangeland area of the <br /> site. Only the appropriate grasses selected by the NRCS will be used. The operator will use the <br /> seed mix from the original permit application below. The seed will be broadcast at the rates <br /> below. <br /> Page 6 of 17 <br />
