EXHIBIT L WORST CASE RECLAMATION SCENARIO <br /> The worst case reclamation scenario at the Yevoli Cobblestone Pit will be when the largest Area <br /> (Area 4) is mined out, and thus the most topsoil and seeding working is needed. Mining <br /> operations will move through the site, staying in the active area. A truck scale and office trailer <br /> will be located near the entrance, and will need to be removed. A detailed breakdown of <br /> reclamation tasks can be seen below. <br /> 1.
