MINING PLAN <br />Spring Creek Pit, operated by Oldcastle SW Group, Inc. dba United Companies of Mesa County, <br />is located approximately one-quarter mile west of 61.75 Road and one-half mile north of La <br />Salle Road in Montrose County, Colorado. The Spring Creek pit is in operation Monday through <br />Saturday, from 7:00 AM to 6:00 PM. <br />United Companies has obtained a Special Use Permit from Montrose County, which allows the <br />pit to expand into two adjacent, northern parcels. Although the gravel pit will encompass an <br />increased area, the expansion is not anticipated to increase operations or generate any additional <br />vehicle traffic. Rather, the expansion will allow the pit to remain in operation for a longer <br />duration of time. <br />The current Spring Creek Pit encompasses approximately 103 acres. The expansion permit <br />boundary is proposed to add approximately 81 acres, with approximately 70 acres being affected <br />lands. Approximately 8 acres located in the northeastern corner of the expansion area has been <br />excluded from the permit area as to not include the Uncompahgre River. The most southwestern <br />portion of the expansion area, which is the long narrow piece of land running north and south, is <br />included in the permit boundary but will not be affected by the mining operations as shown in <br />Exhibit C. <br />Since 2001, the average production for the Spring Creek Pit is 260,000 tons per year with the <br />high year being 367,000 and the low year being 167,000. The anticipated annual production of <br />the expansion sites is expected to be the same. Mining will occur in five distinct phases, in <br />which approximately fifteen to twenty acres will be disturbed at any given time. Each phase is <br />expected to last approximately three to ten years. Ingress and egress to the site will be through <br />the drive north of LaSalle Road and approximately one-quarter mile east of 6100 Road. No <br />additional ingress or egress points are proposed. <br />No historical water conveyances that effect adjacent property owners will be moved during the <br />mining operations. Stormwater controls will be implemented as required by the stormwater <br />permit obtained from the Colorado Division of Public Health and Environment. In general, <br />stormwater controls will consist of a minimum three to five foot earth berm to be placed around <br />the mined area to prevent sediment from migrating off site. Some areas of the mine will have a <br />sloped bank approximately 25 to 30 foot high that will be left in place. It is anticipated there will <br />be no storm water runoff from the mine. Any accidental storm water releases will be addressed <br />in accordance with all local, state and federal regulations. There are no utility or other structures <br />located within 200 feet of the permit boundary. <br />Loaders and/or scrapers will be used to remove the approximate eight to fourteen inches of <br />topsoil. The topsoil will be stockpiled around the perimeter of the mine and some being placed <br />on top of the tall berm that will be left in place during mining. The tall berm is described in the <br />Project Phasing portion of this Mining Plan. The stockpiles will be revegetated to prevent <br />erosion. Once reclamation begins the topsoil will be used for reclamation. After the topsoil has <br />been removed, scrapers and loaders will be used to excavate the approximate one to three feet of <br />overburden. Overburden will be stockpiled along the perimeter of the property, with a portion of
