.• 2:1 slope, and a 0.5 percent sloping top is presented on Figure 1. <br />Typical sections through the pile are shown on Figures 4, 5 and <br />6. <br />CRITICAL STAGES <br />Critical stages of the construction process which will require <br />detailed supervision or verification that they are performed <br />correctly include: (1) periodic testing of the material to <br />verify that the material is being placed and compacted to the <br />specified moisture and density requirements; (2) removal of low <br />strength material to the specified distance from the final toe; <br />(3) initiation of final construction methods; (4) installation of <br />the rock drain and filter cloth and (5) initial placement lift <br />• over the final location of the low strength fine refuse pond <br />area. <br />These conditions are critical for verification that proper <br />construction methods were utilized and for certification by the <br />responsible engineer. <br />Although the hydrologic control structures and subsidence <br />monitoring for the refuse disposal area are beyond the scope of <br />this report they ace important aspects of the stability of the <br />refuse pile. For this reason the plan location of these <br />structures, as presented by GTL, in their January 26, 1981 report <br />with respect to the disposal pile are shown on Figure 7. Design <br />• of these structures have not been varified by Rocky Mountain <br />14 <br />
