5. All slopes on the edges of the permit area will be mined at a 2H:1 V slope in order to <br />maximize the amount of gravel recovered. The scenario of mining all slopes at a 3H:1 V <br />slope was considered, but was not chosen because the operator wanted to extract the <br />maximum amount of gravel possible. Also the large amount of overburden which is <br />present on the site allows for backfilling to take place. Mining the slopes at a 3H:1 V <br />slope would create a situation where the operator would have to haul some overburden <br />offsite or fill to a higher depth on the pit floor. The operator realizes that this will <br />increase the calculated bond for the site, but has chosen to mine at the 2H:1 V slope in <br />spite of that fact. <br />6. In order to not mine through reclaimed areas or leave azeas unreclaimed, the operator <br />wishes to remove the language from the mining plan regarding leaving the option to <br />leave the houses within the mining azea until the end of mining. All houses within the <br />permit area with the exception of the house on the southeast comer of the permit area <br />will be removed immediately before mining takes place in the Phase which the house is <br />in. The text in the mining plan has been modified to reflect this change. <br />7. A permanent access road for farming access will be left around the western and southern <br />toe of the pit. Temporary roads will be left through some of the mining Phases in order to <br />leave access for hauling material from other Phases. All of these roads are shown on Map <br />C-2, and denoted as either permanent or temporary roads. Leaving these roads for access <br />purposes will leave small portions of some Phases unreclaimed until a later period of <br />time. All temporary roads also have a label indicating what Phase they will be reclaimed <br />with. <br />8. The primary secondary containment for the Haldorson Sand and Gravel Mine will consist <br />of a berm with sideslopes which are 3H:1 V and a liner which is petroleum and UV <br />resistant. A diagram showing a typical cross section of this type of containment has been <br />included as well as a specification sheet for a liner that maybe used. The same liner or a <br />comparable liner will be used for all fuel containment on-site. <br />9. As discussed in item #7, permanent and temporary roads will be left in order to haul <br />material from current mining Phases, see Map C-2 for details. These temporary roads <br />will leave access to Phase 5 as well as allowing the material in Phase 5 to be processed in <br />Phase 5. Topsoil and overburden to reclaim Phase 5 will be temporarily stored on Phase <br />B4. This will result in a portion of Phase 4B having to be reclaimed along with Phase 5. <br />10. The crop which will be replanted will be alfalfa. The cost of planting the alfalfa has been <br />included in Exhibit L. <br />11. The dry rangeland seed mix has been amended to include shrubs as suggested in the <br />PAR. <br />12. Montrose County Weed Control was contacted. No known noxious weeds aze present <br />onsite at this time, however weeds that Montrose County identified as weeds to monitor <br />include: Yellow Starthistle, Spotted Knapweed, Diffuse Knapweed, Leafy Spurge, <br />Yellow Toadflax, and Jointed Goatgrass. Annual monitoring of weeds will occur in the <br />summer of each year. Areas identified for control will be sprayed in the fall and possibly <br />
