<br />SLOPE STABILITY <br />INTERIM INSPECTION REPORT <br />AREA Wadae Hichwall drainage fill DATE 06/05/96 <br />TIME 3:15 p.m. by Michael Altavills WEATHER Cloudy and slight wind 65oF <br />1. Debris, organic matter coal, etc., present in fill None visible. Snow has entirely <br />melted from the inspection area. <br />2. General gradation and characteristics of material Reclamation <br />side of pit has been regraded. Hichwall (west side) was recraded complete for <br />in August and now. East <br />September <br /> 1995 and looks good Two areas on hiahwall side will require so me maintenance repairs <br /> Some topsoil has been replaced at the very northern end of the fill area. <br />3. Presence of water, surface and ground None visible. <br /> <br />4. Condition of underdrain (approx. current width, depth, and length), material <br />and characteristic, compaction, presence of water N/A gradation <br />5. General material movement None observed. <br />6. Proximity and treatment of seep points Spoil spring 1000 ft downaradient flowing at a <br />rate of approximately 20-25 apm (visual estimate). <br />7. Condition of slope fill surface (grading, cracks or sloughing, erosion, revegetation) <br />Conditions of recently graded surface were good. Two areas on hiahwall side will require <br />some repair. Some erosion in drainaoe bottom iust prior to enterinc topsoiled and <br />reveaetated area to the southeast. All final drainaoe work will be completed this summer. <br />Good vegetation cover around check dams. <br />8. Recommendation Continued observation of the fill area as final finish grade work is <br />completed this summer Differential settlement and erosion should be monitored and <br />repaired as necessary. This area should be completely retopsoiled and seeded during the <br />reclamation season in 1996 <br />9. Accountability <br />I certify the preceding observations and comments to be true and accurate to the <br />best of my knowledge. <br />REG;S <br />..AL q`'d~~O <br />Michael G. ~l~a,,villa <br />Colorado PE .~~5._ <br />JUN 2 5 1996 <br />Date <br />
