ti <br />EXHIBIT D — Mining Plan <br />The following information pertains to the Colorado Division of Minerals and Geology Permit # <br />1974-069 for Loveland Ready Mix Concrete, Inc.; Larimer Pits. <br />The Mining Plan is described in this section and correlated with Exhibit C-2, Mine Plan Map. <br />Stripping and mining will incorporate conventional aggregate mining methods, including the use <br />of scrapers and dozers to strip overburden, hydraulic excavators and dozers to mine sand and <br />gravel, and haul trucks to move materials on site. All hauling is via internal haul roads on <br />Loveland Ready Mix, Inc. property. Mining will occur year round. <br />Current reclamation is ongoing in cells 18 and 7 as mining has been completed. Mining <br />operation recently began at Cell 20. It is will take approximately 3 years to complete mining at <br />cell 20 before moving to Cell 21. <br />The mining of the new Cell 21 will begin with the removal of topsoil and overburden, which will <br />be stored separately in the storage areas noted on the mining plan map. <br />The test hole logs in Cell 21 show an average overburden depth of approximately 8 to 9 feet and <br />an average gravel depth of approximately 14 to 15 feet. The topsoil in Cell 21 will be stripped <br />and be used to cover the overburden stockpiles, and be seeded for temporary erosion control. A <br />maximum of approximately 30,000 cubic yards of overburden will be stockpiled at Cell 21 at <br />any one time. The stock piles will not exceed 10 feet in vertical height and will be temporarily <br />seeded with drought tolerant native grasses. <br />Cell 21 is approximately 16.25 acres, with a total of 800,000 tons of sand and gravel to be <br />extracted, and 35,000 tons of overburden to be removed, stockpiled, and backfilled back into the <br />pit. The overburden for the pit has a permeability rate that will allow it to be used as a liner for <br />the pit when removal of the sand and gravel is completed. The overburden will be placed in <br />controlled lifts, moisture treated, and compacted to a total approximate depth of 12 feet. This <br />will allow the mined pit area to be maintained as an open meadow as opposed to the recreation <br />ponds found elsewhere in the vicinity. <br />Prior to mining Cell 21, a 4 foot berm will be built along Wilson Ave. and 151 Street to act as <br />natural screening. These berms will be seeded with natural grasses as provided in the <br />Reclamation Plan Exhibit F and irrigated as needed to establish growth. In addition, trees and <br />shrubs will be planted on the berm to meet the City of Loveland's buffer yard requirements. <br />Finally, a 3 wire barb wire fence, with adequate signage, will be maintained along the property <br />line adjacent to Wilson and 15` Street and along the mining boundary between Tract A and B. <br />Currently, there are no sidewalks or pedestrian access, nor are any proposed to the site for the <br />safety of the general public. In addition, the pit location will be set back 200 feet from the <br />residential neighborhood to the south and a landscaped berm will be installed behind the fence as <br />a further deterrent to public access. Loveland Ready Mix has not had an issue in the past with <br />the general public entering active mine sites. <br />
