(c) Water diversions and impoundments; <br />1. Mining will expose groundwater. Silt fences, straw bales and/or berms will be erected <br />around active mining areas so that they will not release sediments during storm <br />events. Site storm waters will be handled as specified in the Stormwater Management <br />Plan (SWMP) for the site. <br />2. There will be 2 water impoundments created, Pond 41 -19,8 acres and pond 42 - 16.1 <br />acres. Other than the creation of two (2) pond water surfaces, site operations will have <br />little to no effect on water rights, drainage or hydrology of the area. Each pond will <br />be required to have a gravel pit well permit and any excavation/pond edges will be a <br />minimum of 100 feet from the Yampa River as per the Colorado Division of Water <br />Resources District Engineer. (Copies of Gravel Pit Well Permit Applications are <br />located in Exhibit M.) <br />3. There will be no disturbance within 100 feet of the Yampa River, Deep Cut Ditch and <br />Brennise water well. If the well is affected, the landowner/applicant will have to <br />deepen, repair and/or relocate the well as per the Exhibit S Damage Agreement (the <br />well is a concrete "cistern type" - 5 feet in diameter and less than 30 feet deep with <br />seasonal water level fluctuations). <br />4. There are no other wells in the proposed area or within 200 feet of the proposed area <br />of operations. There are no planned inlets or outlets for creek waters. Silt fences and <br />sediment retention berms or ditches will be maintained alongside roads and <br />excavation areas to reduce erosion and limit runoff from storm events as necessary. <br />(d) The size of area(s) to be worked at any one time; <br />As stated above in Exhibit D-(a) Mining Plan - Description of Methods, The mine <br />area, as shown on the attached maps, totals approximately 62 acres. Mining/process <br />activities may take place in any of the 2 pond footprint areas at anytime in order to <br />establish the initial 2 separate water surfaces as soon as possible for stormwater <br />control and to be able to dewater from one pond area to the other to assist in the <br />mining operations. Stormwater/sediment pond/trenches (approximately 10x50 feet) <br />will initially be dug in each pond footprint (on the approximate northern ends of <br />ponds). They can either be expanded into the mining/operations area as aggregate is <br />removed and the pond water surface develops or kept separate from the main <br />excavation pit areas to be used as sedimentation ponds/stormwater cutoff ponds for <br />that specific pond. Once established, each pond can also be used to receive pumped <br />water from the other, as operations dictate, to assist in mine pit dewatering activities.
