Q v v v ti'~L.~QRf-'4i~1 ~ U I"J2 For J. A. Kiger October 10, 1995 WEST PIT EXCESS SPOIL FILL CONSTRIICTION DPDATE AND CERTIFICATION During the quarter beginning July 1, 1995 and ending September 30, 1995, I inspected the area in which the west Pit Excess Spoil Fill is being constructed. The purpose of these inspections was to observe the area in which a small spoil slide was removed, inspect the areas currently being topsoiled by a scraper fleet and final sloped using dozers; inspect the fill for areas of water seepage or surface drainage and to satisfy the requirements of CDMG Rule 4.09.1(lla). During the inspections it was observed that the two percent, 25 foot wide catch bench ditch at the 7050 elevation was complete and that the bench at the 7150 elevation was under construction; the surface rock drain down the three-to-one slope was complete from the 7025 elevation to the 7050 elevation, and the truck dump had advanced to the point that the 7200 contour was nearly dumped in. During the quarter several other notable events have occurred in the Excess Spoil Fill Area. The following dates reference the major events that have occurred during the quarter. September 29, 1995 - quarterly inspection of the West Pit Excess Spoil Fill During the quarter the two percent ditch that runs across the face of the 3:1 fill at the 7150 elevations was being constructed. During the quarter the face of the fill was topsoiled by a scraper fleet and a truck and loader fleet. The topsoil had been spread between the 7200 contour and the toe of the fill. (see photographs #76 through #82) Attached to this report are my certification that all construction requirements have been met thus far in constructing the West Pit Excess Fill, and the color photographs as required by the CDMG regulations concerning offsite Excess Spoil Fills. 0 Stephen R.
