Page 2 RECLAMATION PLAN: 1) Slopes: During mining operations, cut or fill slopes should not exceed 3:1 slopes <3 horizontal to 1 vertical). Cut slopes should be scarified a minimum of three inches deep prior to placement of any top soil material, 2) Top Soil: During mining operations, topsoil should be stockpiled to be used in reclamation of the area. Stockpiled topsoil should be protected from wind erosion. After mining operations are completed, the area should be shaped and graded with no slopes exceeding 3:1 above water level and for at least ten feet below water level. Below ten feet, slopes could be 2:1. After scarifying, topsoil should be spread six inches to one foot thick over any disturbed area above water level, except where buildings may be built. A seedbed should be prepared before the soil is seeded to adapted vegetation. For more information on seedbed preparation contact this office. 3) Cover Crop: After topsoil has been spread over disturbed areas and a seedbed has been prepared, the reclaimed area should be seeded to a cover crop. Hybrid forage sorghum is a recommended cover crop. Seeding should be done in May or June at the rate of 10 pounds per acre of Pure Live Seed (PLS) in 7" to 12" row spacings. Grass can be seeded directly into the forage sorghum, see item 6 below. See item 4 below as mulching can be used instead of seeding a cover crop. 4) Mulching: After seeding is completed, approximately 4000 pounds per acre of straw or hay mulch should be applied. This mulch should be anchored. One method is to use a straw crimper and "crimp" the mulch into the soil, This should help to control erosion until the grass becomes established. See attached SCS Standards and Specifi- cations for Mulching. 5) Fertilizer: A soil test should be taken to determine fertilizer recommendations before seeding grass. In the absence of a fertilizer test, then forty pounds of nitrogen and forty pounds of phosphorous per acre should be applied just prior to or during seeding of the area. The fertilizer should be mixed into the soil. 6) Grass Seeding: Grass seeding should be done between November 1 and May 1. Fall seeding is preferable. Seeding should not be done on frozen soil. The seedbed should be firm and weed free. Seeding should be made into a cover crop as discussed in item 3 above. When a cover crop is not used, after the land is seeded to grass, it should be covered with a mulch, see item 4 above. The following seeding recommendation can be changed in consultation with SCS and the Colorado Mined Land Reclamation, phone 866-3567. The following is a seeding recommendation.
