To that <br />end, please find the EROSION CONTROL PLAN enclosed, and note that <br />there are three zones designated to prevent excessive erosion <br />during the continued mining phase of this operation. <br />ZONE #1 is the existing materials storage area. The plan is <br />to construct a berm along the southwest side of this material and <br />to divert the runoff in the directions of the arrows shown on the <br />plan. <br />ZONE #2 is the mined-out area of the pit. The plan is to <br />lower the ground surface area at the base of the slopes to delay <br />the surface run-off and to provide an evaporation area for water <br />collected in these low areas. The water will be ditched in the <br />direction of the arrows shown on the drainage diagram. <br />ZONE #3 is a steep access road for use during the mining <br />operation. Moffat County will build water bars, berms and <br />ditches to control the excessive erosion in this area. <br />It is the Road Department's plan to construct these <br />corrective measures this fall, and to maintain them during the <br />balance of the mining operation - including the duration of the <br />proposed Conversion #1 development. <br />I hope that this plan, and the proposed development, will <br />properly address the need to stabilize this site according to the <br />rules. If not, please contact me. Thank you, <br />s x. pones <br />stant Road Supervisor) <br />ROAD SUPERVISOR <br />P.O.
