SLOPE STABILITY <br />INTERIM INSPECTION REPORT <br />AREA Wadge Hiahwall Drainace Fill DATE _ <br />TIME 9:00 a.m. by Michael Altavilla WEATHER <br />1. Debris, organic matter coal, etc., present in fill None visible. Approximately 1-2' of <br />snow cover still over most of the inspection area. Some snow has melted on south facing <br />2. General gradation and characteristics of material Reclamation complete for now. East <br />side of pit has been regraded. Hiahwall (west side) was regraded in August and September <br />1995 and looks good. Two areas on highwall side will require some maintenance repairs. <br />Some topsoil was replaced at the very northern end of the fill area in 1995. <br />3. Presence of water, surface and ground None visible. <br />4. Condition of underdrain (approx. current width, depth, and length), material gradation <br />and characteristic, compaction, presence of water N/A <br />5. General material movement None observed. <br />6. Proximity and treatment of seep points 5ooi1 sprin^ 1000 ft downgradient was not visible <br />7. Condition of slope fill surface (grading, cracks or sloughing, erosion, revegetation) <br />Conditions of recently graded surface were good. Two areas on highwall side will reguire <br />some repair. Some erosion in drainage bottom lust prior to entering topsoiled and <br />revegetated area to the southeast. All final drainage work and stockoond construction <br />will be completed this year. Good vegetation cover around check dams. <br />8. Recommendation Continued observation of the fill area as final finish grade and <br />maintenance work is completed. Differential settlement and erosion should be monitored <br />and repaired as necessary. This area should be completely graded, retopsoiled and seeded <br />during the reclamation season in 1997. <br />9. Accountability <br />I certify the preceding observations and comments to be true and accurate to the <br />best of my knowledge. <br />APR 0 7 1997 <br />Date <br />
