J. Describe and locate any structures to be constructed (i.e. stockpiles, ponds, <br /> impoundments): <br /> K. Describe anticipated relationship to surface water and groundwater (proximity to <br /> streams,penetration of ground water aquifers): <br /> Previously drilled holes penetrating Belden Shale will be plugged with neat cement grout from the location <br /> of collapse,to surface. MW-1 (south of S. Mosquito Cr)will be plugged to about 160 feet with the initial <br /> cement grout mixed thin (about 30% extra water)to attempt to penetrate out into the formation surrounding <br /> the collapse,then after the thin grout has set for 24 hours, higher thickness grout will be placed by tremie <br /> pipe to fill the hole to surface. Belden is a highly competent confining formation which tends to self-heal, as <br /> determined and supported by numerous water rights court cases since 1970s through mid-1990s. <br /> IV. OPERATION AND RECLAMATION MEASURES: <br /> 1. The Board suggests that a photographic record of the pre-prospecting and <br /> post-prospecting conditions be kept by the prospector. These photos should be taken <br /> from the same location and by the same method to clearly show the pre-prospecting <br /> condition of the land and the reclamation efforts. Upon completion of reclamation and <br /> request for bond or surety release, the Board may consider the photos as evidence of <br /> adequate reclamation,and thus, be able to act more quickly on the request for release. <br /> 2. Provide a description of the native vegetation of the area to be disturbed, including <br /> tree, shrub, and grass communities of the area. Color photographs, sufficient to <br /> adequately represent the ecology of the site and adequately labeled (including date, <br /> orientation and location), may be used in lieu of a written description. Based on the <br /> quality of the photographs,the Division may require additional detail. <br /> MW-2 (vertical borehole drilled to north of No Name Creek)and MW-3(30 degrees off of vertical <br /> hnrehole)will Aso hp ph jqqerl with thin rement qro,it allowed fn ri irp 24 hai incz then topped with thiCkpr <br /> grout to surface, with all grout placed by tremie pipe.

If the depth to refusal is less than 20 feet above the original depth to refusal, then additional <br /> thin grol it will he arlded at a known volume sufficient to cause a rose in the borehole of 30 additional feet <br /> Only when at least 20 feet of rise is achieved from addition of 30 feet equivalent volume of grout will we <br /> then stop and allow 24 ho!irs CuriAg W thOA complete the 5021 With normal thickness grout These <br /> grouting records will be provided upon completion of the abandonment. <br /> Form 2—Public File Page 8 of 14 <br />
