No additional fill placement is <br />anticipated. <br />COVER MATERIAL <br />Final fill configuration has been established and topsoil material has been placed on the excess spoil-fill. <br />The area was mulched and seeded in the fourth quarter of 2003. Soil was placed and spread on the upper <br />most surface of the fill in May of 2004. During the second quarter of 2005, areas disturbed by maintenance <br />of the armored down-drains were seeded using certified weed free straw and the approved rangeland seed <br />mix.

No indication of potential instability was <br />observed. <br />DOCUMENTATION AND OTHER <br />Summer conditions prevail with good vegetative growth due fiequent precipitation this spring and early <br />summer. <br />CERTIFICATION <br />This inspection was conducted by Ronald G.
