• Previous reclamation did not include recontouring of the road cut. Energy Fuels will utilize this road <br />to access the Packrat portal and will reclaim the road after the work at the portal area is complete. <br />Reclamation will include partial backfilling and recontouring of the road cut so that the reclaimed <br />surface better blends with the surrounding area. Water bars will also be installed in their approximate <br />former locations to divert water off the reclaimed road into the natural drainage below. <br />Pulling up all the material from the outside edge of the road is not practical or environmentally sound <br />since the original slope was steeper than 2H:1 V in many places. Replacement of the loose material at <br />this slope angle would likely produce a slope with a low safety factor (i.e., less than 1.3) that is prone <br />to accelerated erosion. In addition, almost all of the material placed on the outside edge of the road <br />during original road construction has revegetated in the intervening years. Pulling this material backup <br />the hill will result in more disturbance and potential erosion in an area that will not be easily accessible <br />after reclamation is completed. It is proposed that only the top 2.5 vertical feet of the outside edge of <br />the road be removed and placed on the inside edge to achieve partial backfilling. This will lessen the <br />erosion impacts compared to more extensive recontouring and the material placed on the road cut slope <br />• (west edge) can be placed to achieve an angle of approximately 4H:1 V, which is more stable, easier to <br />revegetate, and less prone to erosion. The cross sectional area to be cut and filled is approximately 25 <br />square feet, as shown in Figure E-1 below. <br />• <br />Whirlwind Mine 07 (rev. April 08) E-12 <br />
