Dept. of Natural Resources September 10, 1981 Mr. Steven G. Richardson Senior Reclamation Specialist Mined Land Reclamation Colorado Department of Natural Resources 1313 Sherman Street Denver, Colorado 80203 Dear Steve: This letter is in response to your questions of August 25, 1981. The following information is presented in the same order as your questions: The final disposition of the Middle Fork and Davis Gulch dams is still unknown; however, if they are to remain, the access road will be needed for dam maintenance. In the event the dams are removed the meadow fills would also be removed and salvaged. Topsoil will be spread over the disturbed area that the fills occupied and final reclamation would be carried out as outlined in our reclamation plan shown in Exhibit E of the permit application. The cut and fill slopes resulting from the Union Meadow crossings will be revegetated upon com- pletion of the disturbance activities. In order to discourage deer usage of the fill slopes along the road, a mixture of relatively unpalatable grasses will be used. Grass species to be seeded include streambank wheatgrass, basin wildrye, sand dropseed, buffalo grass, blue gramma and tall wheatgrass. The seed mixture will be hydroseeded at a moderate rate, fertilized as required, and hydromulched. Herbicides may be applied if necessary to control weeds and un- desirable plants. we are presently anticipating that 12 inches of topsoil will be salvaged. This would yield approximately 3600 cubic yards of material to be picked up which should yield a swelled volume of 4300 cubic yards. Attachment 1 is a drawing of the proposed topsoil stockpile. Attachment 2 is a soil survey report for the Union Meadows area. A DIVISION OF E%%ON CORPORATION
