xorizontal Alicnment. Slight deviation from the designed horizontal alignment was made <br />f <br />~~ near Rattle Snake Butte (STA 43+00). This was done to avoid blasting the sandstone knob. <br />Road Cuts. Cut slopes were generally flatter then 1.Sh:ly unless rock or consolidated <br />material was encountered. One such area was near STA.s 46+00 to 51+00. The cut slopes in <br />the rock were approximately 1h:ly. <br />Road Embankments. The design required that the embankments be compacted to 90X of Standard <br />Proctor-density. Seventy (70) density tests were performed during construction of the <br />embankments (06/09/92 - 07/21/92). The results of these tests can be found in Addendum <br />C-1. Tests ranged in value from 88X to 700•X of standard Proctor density. Only two tests <br />were below the specified 90X. <br />Twenty-four (24) stability monuments were installed on June 13, 1992 to monitor possible <br />movement of the potentially unstable area between STA.s 45+00 end 56+00. The monuments <br />were resurveyed on July 17, 7992 and August 22, 1992. Survey results indicate that no <br />movement has occurred either above or below the road in this location. The survey notes <br />will be kept on file at the mine site. <br />Embankment slopes were generally constructed et a slope of 2h:ly or less. <br />Drainage. Drainage ditches were constructed es shown on Exhibits 73-19. 1A through 13-19.4A <br />(As-Built drawings). The three types of ditches constructed were "B" and "C" as shown on <br />Exhibit 73-70, Typical Road Details and XRD-G1 ss shown in Tab 13. <br />Culverts. Culverts were installed es per the original design except for culvert G-b. <br />This culvert was eliminated from the road Construction. The reasoning behind this decision <br />we s, upon field inspection, the culvert was not needed end the runoff Could be routed to <br />Pond 005. Culvert G-2 was conservatively designed in the event that runoff from Pond 005 <br />would pass through the emergency spillway or that the road would remain as a permanent <br />structure after the pond is reclaimed. <br />The es-built drawings will replace the design drawings. <br />To the best of my knowledge end belief, field adjustments made during the construction of <br /> <br />
