~~ <br /> <br />Rationale for Recommendation for Approval, Over Objections; Regular 112 <br />Construction Materials New Application, <br />Platte Sand & Gravel, LLC <br />S & H Mine, File No. M-2000-158 <br />April 6, 2001 <br />Introduction <br />On April 6, 2001, the Division of Minerals and Geology ("Division") issued its recommendation for approval of a <br />112 Construction Materials Amendment Application, over objections. This document is intended to provide a basis <br />for the Division's recommended approval over various concerns and reasons for objection to the S & H Mine, File <br />No. M-2000-158. <br />The Platte Sand & Gravel LLC application was found complete and considered filed with the Division on December <br />27, 2000. The site is located southeast of the South Platte River and approximately 2.5 miles northwest of <br />Platteville in Weld County, Colorado. The property is located in portions of Section 26, 34 and 35 of Township 4 <br />North, Range 67 West and portions of Section 2 in Township 3 North, Range 67 West of the Sixth Principal <br />Meridian. The permit area is 1,239.40 acres in size, whereas 831.1 I acres will be mined. A total of 408.29 acres <br />will not be disturbed by the mining operation. The mining area is divided into 9 areas, summarized below: <br />Mining Area Total Area Mined Area <br />Buff Lake 143.7 ] 92.83 <br />Confluence Lake 39.86 23.18 <br />Highlands Lake 78.03 42.78 <br />Longhorn Lake 207.73 118.22 <br />Lake St. Vrain 74.32 30.9 <br />Krystal's Lake 51.54 12.7 <br />Meadow Lake 212.34 154.10 <br />Sand Flats Lake 80.72 61.05 <br />Sharkey's Lake 351.15 296.73 <br />Totals 1,239.40 831.11 <br />No more than 35 acres of mined land will be disturbed at any one time. This includes 1 S acres for processing, batch <br />plant operations, and stockpiles, 15 acres for stripped pre-mining areas and 10 acres for partially reclaimed areas. <br />Mining depth will vary between 45 and 60 feet. Dewatering of the pit is limited to one acre in size in each pit to <br />facilitate the dredging. During construction of the 1-acre pit, water will be removed by pumping from the low areas <br />where water accumulates. Once the starter pit is mined, a dredge will be constructed in the pit. Dewatering will <br />cease, and dredge ("wet mining") will begin from that point in time. The site will be reclaimed to achieve a <br />combination of postmining land uses including recreation and wildlife habitat. <br />
