EXHIBIT D - MINING PLAN <br />GENERAL CONCEPT: <br />The site consists of quaternary sand and gravel deposits on top of a bench of the Lewis Shale Mesa Verde Group, <br />located on the East side of the San Juan River Valley, essentially at the Confluence of the Rio Blanco with the Rio <br />San Juan. Mining will be limited to the upper bench, and will not be done below the cliff along the river (or in the <br />floodplain). Except for grading necessary to construct the access road (connecting the existing road and bridge with <br />CR -500) there will be no operations below elevation 6640. <br />Activities west of the San Juan River will be limited to the construction and use of the access road, and <br />necessary drainage, which will be permanent. This uses part of the existing access road which goes through the <br />ranch headquarters, so that pit traffic goes straight to CR -500. This road, including the bridge, will be maintained by <br />the operator during mining operations. No improvements or additions to this road are within 200 feet of the irrigation <br />ditch or other significant manmade structures other than those of the landowner. <br />Mining of the site will be done in an estimated 25- to 30 -year period, beginning as described above, moving <br />south, then east and north, to mine out the southern portion by 2026 (12 years), then continuing north to finish in the <br />northeast corner in 2040 (26 years). During this period, two general areas will be used for plant operations: in the <br />south 2014- c2027, and north c2027 -2040. The main haul road east of the existing intersection at the top of the face <br />of then bench (more than 200 feet from the irrigation ditch) will be shifted as necessary to support the plant area and <br />operations. <br />The other initial activities on the site will be (1) necessary excavation past the road junction to widen <br />existing trails for access and establish an area to locate scales, (2) clearing and grubbing the initial plant site, <br />stockpile areas, and access to the area to be mined in the first year, which will (3) be stripped. Soil from the plant <br />site and initial area to be mined, as well as from road work on top of the bench, will be stockpiled long -term for <br />reclamation <br />Access from approximately 200 feet west of the bridge to the top of the face of the bench will be single, <br />one -way alternating traffic. Approximately 300 feet of the access road (immediately east of CR -500) will be two -lane <br />(26+ feet wide) to allow for stacking of trucks as part of the alternating traffic pattern. <br />Issues of concern: These existing slopes are permanent but will be subject to engineering evaluation to <br />determine safety and what actions (if any) are necessary to stabilize slopes both during and after mining operations. <br />Such actions which might be implemented as necessary include grouting, use of retaining walls (such as sandbags, <br />KeystoneTm blocks, wire mesh, and gabions). Evaluation will be done at the beginning and end of each season of <br />operations, and on completion and the Operator commits to stabilizing the slopes as necessary. <br />The plant site, including raw material and product stockpiles, will occupy approximately 180,000 SF (4.1 <br />acres) and the initial topsoil stockpile will use approximately 30,000 SF (0.7 acres). Soil will be stripped from this <br />site, and the site will be graded and leveled as necessary for stockpiles, traffic, and plant set -up and operations. Soil <br />from this plant site will be stockpiled in the initial soil stockpile; other materials excavated to level and shape the site <br />will be used to create a temporary berm for visual and noise control to the south (nearest neighbor). Some soil may <br />be placed on this berm to allow temporary seeding with grass to further reduce visual impacts. <br />Actual extraction operations will begin just east of the soil stockpile (east of the initial plant site), <br />approximately 1000 feet north of the southern permit boundary. This will minimize impact by operations at surface <br />level for neighbors to the south. The object is to have as much mining in the south 113 of the site to be done by <br />moving the highwall TOWARDS the neighboring properties, to reduce noise and visual impact. For the first four <br />years, excavation will move to the south, with an estimated 2.1 acres mined each year. Due to terrain and geology, <br />depth will vary from 20 to 110 feet, and expected to average about 30 feet. Bench height will be limited to 30 feet <br />and bench width will be a minimum of 2 times bench height, unless engineering evaluation determines that a <br />higher /narrower bench is safe IAW MSHA requirements. <br />C &J Gravel Products, Inc.
