04004 <br />Exhibit E -Reclamation Plan <br />Overview <br />Banks and Gesso, LLC <br />As with the currently permitted mine area, the new properties will be reclaimed to lined <br />water storage reservoirs. Each of the five additional pits will either be sealed with a <br />slurry wall or clay liner. The applicant proposes to bond each phase individually, and to <br />determine the type of lining prior to posting a bond for that phase. Please see Exhibit L <br />for more information regarding this phased bonding request. The resulting water storage <br />from each of these phases is approximately as follows: <br />Phase Name Water Surface <br />Area (Acres) Volume of <br />Water Storage <br />Acre-Feet <br />Hill-Eber-Oakle Pit 37.65 796.69 <br />Parker-Panowicz Pit 16.65 230.44 <br />Swin le North Pit 32.06 684.50 <br />Swin le South Pit 30.54 417.88 <br />Golden Pit 17.71 302.91 <br />TOTALS 134.61 2432.42 <br />Reclamation Process <br />Land disturbance within each new phase area will begin with removal and stockpiling of <br />topsoil prior to mining. Topsoil will be utilized for future surface reclamation as a plant <br />growth medium and as a component of backfill for mined pit-slopes. Topsoil stockpile <br />berms will be strategically placed throughout the new mine areas to facilitate easy <br />access for use in reclamation. Stockpiled topsoil that will remain in place for more than <br />one year will be revegetated with a temporary seed mix to keep the topsoil fertile. <br />The mined slopes will be reclaimed to a minimum slope ratio of 3:1. These slopes will <br />be constructed using a combination of stockpiled overburden from stripping operations <br />and weathered shale bedrock that is scraped from the pit floor during mining. If slurry <br />walls are not constructed at the onset of mining, the weathered shale bedrock will be <br />compacted to create a solid clay liner that will seal the mine cells off from the <br />surrounding groundwater regime and allow the site to be used as water storage <br />reservoirs as an end-use. <br />Excess topsoil will be combined with overburden and used for backfill, or sold. If <br />additional backfill material is needed, waste fines from processing operations may be <br />used. Excess overburden will be sold or disposed of off-site. It is not expected that <br />imported material will be required to complete the reclamation. <br />Topsoil Preservation <br />Topsoil will be stored in stockpiles and will be located within the permit area in locations <br />as close to final placement areas as possible. Topsoil that is needed for later use in <br />revegetation efforts as a plant growth medium will be stockpiled separately. It will be <br />seeded with a temporary seed mix (see Table E-3 later in this section) to help preserve <br />the fertility of the soils if the stockpile is to remain in place for more than one growing <br />Fort Lupton Sand and Gravel Mine - L.G.
