6.4 SPECIFIC EXHIBIT REQUIREMENTS - REGULAR 112 OPERATIONS <br />The following items must be addressed by the applicant in order to satisfy the <br />requirements of C.R.S. 34-32.5-101 et seq. and the Mineral Rules and Regulations of the <br />Mined Land Reclamation Board: <br />6.4.3 EXHIBIT C - Pre-mining and Mining Plan Map(s) of Affected Lands <br />1.) Contour lines are provided for the expansion area; however, the way they are labeled <br />is confusing. There are multiple numbers along the contours expressing the elevation. It <br />is unclear which elevation designation goes to which contour. Please clearly label the <br />contours in such a way that the direction and rate of slope can be determined. <br />2.) Also, in order to evaluate the present level of disturbance for the current affected land, <br />please submit a topographic map with contours of sufficient detail to determine the <br />direction and rate of slope for all the current affected land within the permit area. This is <br />necessary in order to evaluate the financial warranty. The Division will needed to know <br />the angle of the current pit slopes to determine how much earthwork is needed to reclaim <br />the land at the present time. <br />6.4.4 EXHIBIT D - Mining Plan <br />3.) Please display the location of the sediment ponds on the Mining Plan Map. <br />4.) According to page D3 of the mining plan, you state that Lafarge will maintain a 100 <br />foot setback from the Cache la Poudre River. The mining plan map indicates that the <br />present mining boundaries and the proposed mining boundaries are not at the 100 foot <br />setback. They are indicated to be much closer than 100 feet for the majority of the site. <br />Please update the mining plan map and re-draw the mining boundaries to be located at <br />the 100 foot setback. <br />5.) Please state the exact amount of topsoil and overburden that will be stripped. Please <br />keep in mind all topsoil removed will need to be used for reclamation. <br />6.4.5 EXHIBIT E - Reclamation Plan <br />6.) On page E1 you state topsoil will be segregated and stored separately from the <br />overburden material. However, on page D2 you state there will be no permanent <br />stockpiles of overburden and topsoil on the property. Please explain these statements; it <br />is unclear if topsoil and overburden will be stockpiled on the property during mining. If <br />you will temporarily store topsoil and overburden please show where these piles will be <br />located on the mining plan map. <br />7.) Any topsoil and or overburden pile that will be left in place for over 180 days will <br />need to be stabilized from wind and water erosion with vegetative cover. Please commit <br />2
