Page 4 of 7 <br />Specify the quantity of each grass and forb species as pounds of pure live seed per acre; <br />You need to provide the NRCS recommended grass seed mix species in pounds PLS /ac. <br />What seed mix will be used to stabilize the topsoil stockpile? <br />(iv) specify the application method for grass and forb seeding. If the seed is to be broadcast, the <br />application rate shall be twice the rate required for seed drilling. If the seedbed has not <br />been adequately roughened prior to seeding, the seed shall be raked or harrowed after <br />broadcast application; <br />(v) if a mulch is needed, specify the kind to be used, the crimping method, and rate of <br />application; and <br />(vi) explain the establishment methods for each species of shrub and/or tree, and state the <br />number of each to be established per acre. <br />(d) Specify which ponds, streams, roads and buildings, if any, will remain after reclamation. These features <br />must be shown on the Exhibit E - Map. Scale needs to be removed from reclamation map if it will be <br />removed at end of mining. If ponds are part of the Reclamation Plan, slopes from 5 vertical feet above <br />to 10 vertical feet below the expected average water level cannot be steeper than 3H:1 V; remaining <br />slope lengths may not be steeper than 2H:1 V. Where wildlife habitat is the proposed future land use, <br />shorelines should be irregularly shaped to promote a diverse wildlife habitat. The Colorado Division of <br />Wildlife (DOW) must be consulted where wildlife use is the proposed future land use. <br />(e) Specify the reclamation treatment of any waste rock dumps, tailing impoundments, underground mine <br />openings, ditches, sediment control facilities, buildings and other features specified in your mine plan <br />but not previously addressed in the Reclamation Plan narrative. These features must be shown on <br />Exhibit E - Map. This should describe the measures taken to minimize disturbance to the hydrologic <br />balance, prevent off -site damage, and provide for a stable configuration consistent with the proposed <br />future land use. <br />(f) All Limited Impact 110 applications must provide an estimate of the actual costs to reclaim the site <br />based on what it would cost the state using an independent contractor to complete reclamation. Include <br />the unit costs for the following activities as appropriate to the operation: backfilling, grading, topsoil <br />application, seeding, mulching, fertilization, and labor to complete reclamation. Determine and specify <br />the point 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. Unit costs <br />(cost per cubic yard), volumes, haul or push distances, and grades must be included when backfilling <br />and grading is part of the Reclamation Plan. Volume and unit costs for finish grading subsoil and <br />topsoil application must be provided in terms of cost per cubic vard. The estimated cost for fertilizer, <br />seed and mulch acquisition and application must be provided as cost per acre. <br />(2) Equipment costs must include such factors as equipment operator wages and benefits, fuel and <br />lubricant consumption and depreciation. The cost to mobilize and demobilize the equipment from the <br />nearest population center should be estimated. <br />(3) All items referenced in the Reclamation Plan must be included in the cost calculation. These items <br />in addition to earthwork, such as detoxification, building demolition, fencing, monitoring well sealing or <br />stream channel reconstruction must also be included in the reclamation cost estimate. <br />(4) After the direct costs noted above have been estimated, the Office may add up to an additional <br />maximum eighteen and one -half (18.5 %) percent of that total, which includes private contract, typical <br />overhead costs. This additional cost is required to cover indirect costs that an independent contractor would <br />
