BISiNEA~AND RECLAMATION DIVISIOI L i roo n , CQp~,~~Bp) Neturel Resources Date: January 2, 1985 File Code: 110 ~fo~ac/2 ems,,, n.rk} l~` The purpose of this trip was to assist Randy in preparing a ~1e reclamation plan for the Robinson Brick and Til r• on their Ute Mine Site. This is an exis ing clay pit part of which has been ~, c ose an needs to be reclaimed according to Colorado Mined Land 1 ' Reclamation Division regulations. The site is located approximately two miles north of Sedalia. Randy and I met with Mike Leidich, Mining Engineer for Robinson Brick and Tile Company, to arrive at the necessary planning decisions. The following represents a summary of these decisions and will constitute the basis of the reclamation plan. SITE PREPARATION The area to be revegetated has already been backfilled to acceptable slopes and topsoiled. However, some gullys and rills have developed near the bottom of the slope. These will be shaped in and smoothed before reclamation begins. In addition, contour furrows will be constructed across the entire slope. The contour furrows will have a minimum cross section area of 48 square inches and be spaced no further than 10 feet apart horizontally. 2. SEEDBED PREPARATION Seedbed preparation will be carried out inorder to control the weeds on the site and loosen the compacted surface soil. Seedbed preparation will consist of discing twice and harrowing in early spring (April). 3. FERTILIZATION Nitrogen and phosphate will be applied at a rate of 40 pounds per acre available N2 and P2O5. Application will be immediately prior to seeding. Rate of aplicatien should be modified according to the results of a soil test. 4. SEEDING OPERATION Seed will be planted to a depth of 1/2 to 3/4 inch using a grass drill equipped with depth bands and packer wheels. Time of planting will be from April 15th to May 10th. Species to be planted and seeding rates will be according to the attached specification sheet. Some of the species to be planted will be provided through the SCS Plant Materials Program. Therefore each of the species will be planted into evaluation plots laved-out prior to drilling the grasses.
