BUCKLEN EQUIPMENT CO <br />BUCKLEN EQUIPMENT CO PIT - ID# M- 1982 -131 I Technical Revision <br />The saleable material will be excavated using 3H:1V slopcG 1H:1V slopes. No backfilling of <br />slepeswill_occur. Slopes will be backfilled using unsaleable material from within the mine <br />limits which includes salvaged overburden and underlying clays. All slopes will be ripped <br />prior to topsoiling. <br />All grading will be done to minimize erosion and siltation. Best management practices will be <br />used on stockpiles. All erosion that will occur would be confined to the property and not impact <br />adjacent property owners. Backfilling of shoreline slopes will be done in controlled lifts <br />using standard practices accepted for the construction of embankments that are subject <br />to water storage. The Bucklen Equipment Company will retain a geotechnical testing firm <br />to confirm that the backfill replaced on the pit slopes is adequately compacted. Backfill <br />will be tested every 3,000cy for the first 100,000cy. If all tests are passing in the first <br />100,000cy, then the backfill will be tested every 5,000cy. The material already placed at the <br />time of this Technical Revision will be potholed at varying locations and elevations to <br />verify adequate compaction. <br />All grading and topsoiling of pond shores will be done as soon as practicable by the Operator. <br />The proposed timetables will be followed as long as mining keeps up with market conditions. The <br />operator will reclaim based on keeping the Table of Disturbance within the limits set in the Mining <br />Plan. <br />There is no acid forming material associated with the mining operation and any refuse will be <br />disposed of in an appropriate manner. <br />There are no drill holes or auger holes associated with the project. <br />The maximum slope in the lake will be a 3H:1V. <br />WATER <br />The disturbances to the hydrologic balance will be minimized by the operator. The amended land <br />will be mined in the same manner as the existing mine site. The operator commits to: <br />1. Comply with all applicable Colorado Water Laws and regulations governing the injury of water <br />rights. <br />2. Comply with applicable Federal and State water quality regulations. <br />3. Comply with any requirements of the Clean Water Act and any requirements that may be <br />imposed by the Section 404 Dredge and Fill permits. <br />Applegate Group, int. <br />
