EXHIBIT E United States NATURAL P.O. Box 127 Department of RESOURCES Hugo, CO 80821 Agriculture CONSERVATION (719) 743-2408 SERVICE ----------------------------------------------------------------- Subject: Pickenpaugh Pit Admendment Date: April 28, 1997 To: Pete Aragon The vegetative description in the general area of the pit location consists mainly of a mixture of native grasses and miscellaneous forbs on a moderately steep drainage. The predominant grasses consist of blue grama, prairie three awn. Forbs are a native mixture of annual and perennial forbs. For soils description see attachment. Enclosed is a admendment to the Pickenpaugh Pit planning reclamation recommendations for the pit located in the 9 E, NE quarter of section 14-14-58. Planning considerations for reclamation of the site consists of: 1 . Top soil should be stockpiled before mining begins and spread evenly over the surface after reclaimed. Soils must have sufficient depth to support the grass mixture to be seeded. The area should be shaped to the undisturbed area. Slopes should not exceed 3: 1 and should be flatter where feasible. 2. The seedbed should be well settled and firm but not compacted. If heavy equipment traffic has compacted the area it should be ripped and smoothed. The seedbed should be free of weeds. 3. A soil test should be performed to determine the proper fertilizer requirement in both types and amounts. In lieu of a soil test the planting area should be fertilized at a rate at least 40 lbs. of nitrogen and 40 lbs. of phosphate. Animal manure may be used to supply all or part of the nutrients. Fertilization should occur around seeding time of the grass. 4 . The seed mixture should consist of blue grama, sideoats grama, switch grass, and little bluestem ( see attached seed sheet) . Grass drilling should occur between November 1 through May 20th. Weeds should be control mechanically or chemically until grass is established. Grazing should be excluded for two growing seasons from the time of planting from the seeded areas. Fencing maybe needed to achieve this. S. A minimum of 4000 lbs. of grass (native) mulch per acre should be applied to the surface after the grass has been seeded to hold the ground until the grass has established. The mulch should be crimped into the surface with a mulch crimper. The mulch should be weed free and not moldy. If you need any further assistance please contact us. Brian C.
