Please clarify if the pit will be lined or <br />if there are subsurface barriers which may impact the flow of groundwater, or <br />otherwise explain how these comments pertain to the mining operation. <br />The purpose of including this report is to assure the Office that whether basins <br />are lined or unlined, as long as the surface elevation of the water within the <br />basin is equal to the surface elevation of the surrounding groundwater, <br />equilibrium will occur and the effects of shadowing and mounding will not be <br />evidenced. In response to subsequent dialogue with the Office, lining of the <br />basins is an option included under this submittal, and a Technical Revision will <br />be filed with the Office at the time of such determination to construct such a <br />basin. <br />Given the elevation and location of the lands to be extracted to the surrounding <br />lands, flanked by homeowners to the south nearly 25.0± above the site, and <br />natural barriers of post mined land to the east and the Cache La Poudre River to <br />the north, followed by industrial lands set substantially away from the location, <br />in this instance the operator does not believe shadowing and mounding will have <br />an effect on surrounding lands. The operator does not discern how monitoring <br />for shadowing and mounding in this instance creates a benefit. <br />6.4.9 Exhibit I - Soils Information <br />25. The Applicant has indicated the topsoil will be windrowed around the <br />perimeter of the reservoirs. Does this include the portions of the reservoirs that <br />lie within the floodplain? All product, overburden, and topsoil stockpiles should <br />be located outside the boundaries of the 100-year floodway, if possible. <br />Consistent with Item 14, above, Minor soil stockpiling within the floodplain will <br />be oriented in a manner along the perimeters of the basins to aid planned <br />reclamation, and will not in the majority exceed 5.0± feet in height above <br />original ground. Any additional soils pending sale, or needing stored for later <br />reclamation beyond that practically stockpiled as previously described, will be <br />Varra Companies, Inc. correspondence to the Colorado Office of Mined Land Reclamation (OMLR) 14 <br />in reply to OMLR correspondence of 4 October 2010 - Western Sugar Reclamation Land Development Project <br />- M-2010-049.
