AM-04 for 120 Estate Partners File M-2001-085 <br />Rule <br />6.4.1 (A) Legal Parcell S1/2, SWl/4, Sec. 35, T1S, R67W Adams County Colorado. <br />(Map attached) The site is an active mine. <br />6.4.2 Site description: This site is located North of 120`' ave. and West of the Fulton Ditch. <br />The site is an operating gravel pit that is more than 80% mined. The surface area originally <br />was 44 acres, an access road and set backs have reduced it to about 38 acres. <br />6.4.3 © Maps attached.. The only change to the original plan it to lower the +/- 20 acre area in <br />the South East area of the pit. The removal of the clay stone to produce the clay liner will <br />result in a lower of the area approximately 12 feet. <br />6.4.4 Mining plan. This site has a slurry wall installed as per the original permit. The wall <br />did not reduce the infiltration sufficiently, to meet the State Water rules for water storage. <br />Due to the fact that the leaks in the wall could not be isolated, the owners plan to place a <br />clay liner over the entire site. The intent is to finish the removal of material the summer of <br />2010, and place the liner concurrently with the final excavation. <br />We will create a slope of 3:1 which is consistent with our original plan. <br />6.4.5 Reclamation Plan. (E) The top of the wall will +/- 5037 ft. there will be a I Oft. Perimeter <br />road. All areas above an elevation of 5034 ft will be plated with top soil and seeded. <br />SOURCE OF MATERIAL.. The material is the clay stone that is found in sufficient amounts on <br />the floor of the pit. <br />ENGINEERING DESIGN. See the attached Ground report. <br />INSTALLATION PLAN. The plan for the installation is to: <br />1. Remove the clay stone from the floor, this material will be reduced in size to allow <br />compaction of the material when placed on the slope. <br />2. Use an excavator to open a 4ft. Key way at the proposed toe of the slope. <br />3. Water and compact the material using the hauling units (scrapers), bringing the material <br />up in lifts of 6" or less. This material will be tested for compaction by Ground Engineering. <br />4. SCHEDULE. We plan to begin the processes of exposing the perimeter and clay stone <br />during the month of November with completion in January. <br />TESTING AND CERTIFICATION: See Ground proposal.
