The maximum area in the converted Hansel Pit #1 that could require seeding is 37.1 acres. That is the total affected area minus the dry creek bed which will not be seeded. The site will be graded and sloped as it is mined. There is minimal topsoil at the site. Banks will be reclaimed. Stockpiled topsoil will be re- applied to the excavations outside the flow area. A cover crop will be established on the areas outside the creek and on disturbed banks. After the cover crop is established, the grass will be planted as recommended by the local Natural Resource Conservation Service. The cost units below already indude labor and fuel. The cover crop, manuring, and grass seeding cost were obtained from the Natural Resource Conservation Service and have been based on Conservation Reserve Program costs. The other unit costs were obtained from a local contractor who is equipped to perform reclamation if Crystal Springs Ranch Inc. were to default on the reclamation plan.
