<br />• Revision k I - Page B o(30 <br />Exhibit E <br />Reclamation Plan <br />Part 2 a <br />The reclamation proposed for the project site is to return the project site similar to its original <br />topographic condition in order that it may be developed in the future for commercial or industrial <br />uses. The site has been subdivided into five lots, and is zoned 1-I -Light Industrial. Properties <br />adjacent to this project are zoned for industrial uses. <br />In general, reclamation of the site will consist of backfilling and compacting the mined azea with <br />the onsite overburden material and imported fill. Imported fill materials will consist of inert, <br />non-hazardous soils, concrete, and rock. No imported fill materials shall have a dimension larger <br />than two (2) feet on any side, and no rock or concrete material larger than six (6) inches in <br />diameter will be placed within the final two feet of final grade. <br />The site will be regraded in accordance with the reclamation plan, which is essentially the original <br />topographic condition. However, a 109,000 cubic foot retention pond will be constructed on the <br />west property line to address drainage issues associated with the project site. The pond is sized, <br />and is proposed to be constructed in accordance with the requirements of the S[ormwo[er <br />Ma»agement Manual for the City ojGrand Junction and Mesa County. The site will be planted <br />with a diverse seed mix containing Jose Tall Wheatgrass, Alkali Sacaton, Western Wheatgrass, <br />and Galleta. <br />All internal site gravel haul roads, material stockpiles, settlement ponds and noise berms will be <br />eliminated. The site will have a slight gradient to [he west, with no slopes greater than I%. The <br />fencing around the permit area perimeter will remain. <br />The reclamation proposed for this site, vacant industriaVcommercial land, is appropriate <br />considering the surrounding site constraints, mainly the City of Grand Junctions Persigo <br />Wastewater Treatment Plant located west of the mining site. <br />Typical Reclamation Sequence: <br />As discussed in Exhibit D, mining will be progressive across the site, with [he backfilling <br />operations following behind the sand and gravel highwall area. The backfill will be placed in <br />compacted, horizontal layers, or placed on a slope that is accessible for equipment to place and <br />compact the fill. Backfilling operations will not take place in an "underwater" condition because <br />the backfilling operations will be following the active sand and gravel mining highwall area, <br />which will be dewatered. <br />Once backfill material has been placed to the elevations specified in the reclamation plan, topsoil <br />placement, mulching, seeding and fertilizing operations may be delayed until an area a maximum <br />of ten acres is size can be worked. Once a 10-acre maximum area is available to work, the topsoil <br />placement, mulching, seeding, and fertilizing operations will take a minimum of two months to <br />complete. <br />Stockpiled topsoil material that was stripped and stockpiled in the buffer areas prior to the mining <br />operations, will be spread across the reclamation area. Topsoil material shall be spread to provide <br />a minimum depth of two inches. <br />
