I10 Permit Application Colorado Division of Reclamation. Mining and Safety <br />may not be steeper than 2HAV. Where wildlife habitat is the proposed future land use, <br />shorelines should be irregularly shaped to promote a diverse wildlife habitat. The <br />Colorado Division of Wildlife (DOW) must be consulted where wildlife use is the <br />proposed future land use. <br />Response: The storm water retention pond located on the south boundary of the borrow <br />pit will be filled in, graded to accommodate water flow off of the reclaimed borrow pit, <br />and seeded. No ponds, streams, or buildings will remain after reclamation. The existing <br />road included in the permit area will remain following reclamation. <br />(E) Rule: Specify the reclamation treatment of any waste rock dumps, underground mine <br />openings, ditches, sediment control facilities, buildings and other features specified in <br />your mine plan but not previously addressed in the Reclamation Plan narrative. These <br />features must be shown on Exhibit E - Map. This should describe the measures taken to <br />minimize disturbance to the hydrologic balance, prevent off-site damage, and provide for <br />a stable configuration consistent with the proposed future land use. <br />Response: The clear water diversion around the pit will be reclaimed by filling it with <br />material originally derived from the diversion. If present during installation, topsoil will be <br />windrowed adjoining the diversion and reapplied, seeded, and mulched during <br />reclamation. The culverts in the road will remain and will continue to move water across <br />the roadway. No alteration to the hydrology of the site is expected from the use of the <br />culverts. The catchment for both culverts is minor. Silt fencing on the downhill side of <br />the road way will be maintained for two years or until vegetation is established on the <br />borrow pit area. <br />(2) Rule: All 110 Limited Impact applications must provide an estimate of the actual costs to <br />reclaim the site based on what it would cost the State of Colorado using an independent <br />contractor to complete reclamation. (Such estimates are not required for activities <br />contemplated by the operator and approved by the Office to be outside the scope of the <br />proposed reclamation plan.) The unit costs should include estimates for the following <br />activities as appropriate to the operation: backfilling, grading, topsoil application, seeding, <br />mulching, fertilization, and labor to complete reclamation. Determine and specify the point <br />during the operation when the site has reached a point of maximum disturbance. The cost to <br />reclaim the site to the specifications of the Reclamation Plan at this point must be estimated. <br />Unit costs (cost per cubic yard), volumes, haul or push distances, and grades must be <br />included when backfilling and grading are part of the Reclamation Plan. Volume and unit <br />costs for finish grading, subsoil and topsoil application must be provided in terms of cost per <br />cubic yard. <br />Response: The estimated cost to conduct reclamation of the permit area by a third party is <br />detailed in Table 2. Costs shown in the Reclamation Plan (Exhibit E) represent on-site work <br />and material subtotals used in the calculation of the estimates presented in Table 2. <br />(A) Rule: Equipment costs must include such factors as equipment operator wages and <br />benefits, fuel and lubricant consumption and depreciation. The cost to mobilize and <br />demobilize the equipment from the nearest population center known to have the required <br />equipment availability should be estimated. <br />Tetra Tech April 2008 (May 2008 Application Amendment Page) 14
