These ttlaximttm emissions will be 11.40 tons the fast year, then decrease to one to two <br />tons the third and fourth year, then increase to 5.95 tons the fifth yeaz. <br />Topsoil Stockpile <br />Process Description <br />Contemporaneous reclamation procedures will be used at the Lorencito Canyon mime. As each <br />surface area is mined out, overburden will be placed on the mining azea followed by topsoil <br />replacement and revegetation. Therefore, the maximum amount of time that topsoil will be . <br /> <br />
