Ron Thompson was present,representing New Elk Coal Company. The weather was warm and clear on both days. The ground was very dry. (Fire conditions in the area were a great concern, and the East Peak fire was burning near Walsenburg approximately 30 miles to the north.) EXCESS SPOIL and DEVELOPMENT WASTE—Rule 4.09 Placement; Drainage Control; Surface Stabilization: Fills 7, 8, and 9 were inspected. All three fills appeared stable;no gullies were seen and down drains were in good condition. Rills on Fill 8 have been repaired, and no new ones were seen during the inspection. A gully on Fill 9 has been repaired. HYDROLOGIC BALANCE -Rule 4.05 Drainage Control 4.05.1,4.05.2,4.05.3; Siltation Structures 4.05.5,4.05.6; Discharge Structures 4.05.7, 4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; Surface Water Monitoring 4.05.13; Drainage—Acid and Toxic Materials 4.05.8; Impoundments 4.05.6,4.05.9; Stream Buffer Zones 4.05.18: The following ponds were inspected: 6, 7, 8, 9A, and 9B. All of the ponds were dry at the time of the inspection. At all ponds,the embankments and spillways were found to be in good condition. Other observations concerning the ponds: • Above Pond 8, a smaller pond was holding water but not discharging. Per Mr. Thompson,this is affiliated with a gas well. • Pond 913 requires cleaning around the riser pipe (as noted in previous inspections). The following culverts were inspected in chronological order(numbers per proposed map): C3, C2,C19, C4, and the culverts along the road to Pond 8. Most of the culverts meet the PAP specifications and are functional,requiring no immediate maintenance. Culvert 9 still needs to be flushed out. The following ditches were inspected(in chronological order): D3,the ditch above Pond 913,D19,D20, D18, and the ditch that flows into the western down drain of Fill 7.
