EXHIBIT E RECLAMATION PLAN (CONT) use as a commercial/industrial area for parking county equipment. This is consistent with that we have found in the existing mine. The floor remains stable no matter the amount of rain or snow that collect on it. Over time the moisture soaks into the gravel layer and does not runoff the site. The seed mix to be used on the slopes is shown below. This mix is used on all of our lower elevation mines in the county and has prove to be very reliable. The Reclamation Plan information for the site is described in the 1993 reclamation plan document and will be applied to the new area, with the exceptions noted above. PROPOSED SEED MIX Species Lbs/Acre Western Wheatgrass (Arriba) 3.00 Slender Wheatgrass (Revenue) 3.00 Bluebunch Wheatgrass (Goldar) 1.50 Big bluegrass 0.50 Sheep Fescue (Covar) 0.50 Lewis Flax 0.25 TOTALS 8.75 Using this mixture will provide approximately 41.5 seeds per square foot. It is a native mixture that should restore the site to its existing use. If the seed is broadcast, the amount will be increased doubled and spread on a rough surface. The seeded areas will then be dragged or raked thoroughly to set the seed. It has been our experience on other operations that the seeded area will have a heavy cover of weeds after the first year. The second year there are fewer weeds as the grasses start to take hold. By the third year the weeds are mostly gone and the grass has established itself so it will grow in future years. These weeds also tend to shade the seedbed, retain snow in the winter and act as a wind break for the newly emerging grasses. WEED CONTROL The revegetated areas will be monitored closely each spring for the first two years to determine if noxious weeds are invad- ing the area. Weed control will be initiated if the problem becomes serious or if an excessive weed cover is still present at the end of the second year. In no way should this be taken to mean that we will try to eradicate all the weeds from the site. Some weeds are beneficial to the upland game species,in the area, they provide important protection from the elements during winter and nesting sites during the spring. Total eradication of weeds from the site is not necessarily desirable, so we will be using controls on the noxious weeds and letting the rest grow in select areas. It may be necessary to control weeds by mowing after the first year, the feasibility of chemical weed control methods will be studied should other forms not work. Control of noxious weeds is important to the state so we will follow USDA Extension Service recommendations to control them. A weed control plan was submitted to the Division in July 2006. 7 (revised 7/31/08)
