No representative <br />of Seneca Coal Company was present during the inspection. Weather conditions at the site were sunny and dry at <br />the onset, but heavy rain set in on the afternoon of October 4 th . No maintenance or reclamation activities were <br />observed during the inspection. <br />AVAILABILITY OF RECORDS – Rule 5.02.4(1): <br /> Records were inspected at the Sage Creek Mine and Seneca Coal Company offices. All required records <br />were available and current, as documented below. <br /> <br />FISH and WILDLIFE – Rule 4.18: <br /> There were mallards on Pond 011, and numerous bluebirds along Haul Road A. <br /> <br />HYDROLOGIC BALANCE - Rule 4.05 Drainage Con trol 4.05.1, 4.05.2, 4.05.3; Siltation Structures 4.05.5, <br />4.05.6; Discharge Structures 4.05.7, 4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water <br />Monitoring 4.05.13; Surface Water Monitoring 4.05.13; Drainage – Acid and Toxic Materials 4.05 .8; <br />Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br /> Ponds 011, 011A, 012A, 013 and 014 were holding water below the discharge level. Ponds 010 and 012 <br />were discharging clear water. All pond embankments were stable and vegetated, and all spill ways were stable and <br />unobstructed. There were small cracks on the crest of Pond 012, but they appeared to be surface desiccation <br />cracks that should not affect the stability of the embankment. The rip rap in the emergency spillway of Pond 012 <br />was still co vered in dirt for a crossing utilized while construction was underway in the area. The spillway was still <br />functional, but the rip rap should be restored in this section to prevent sedimentation offsite if water were <br />discharged through the spillway. ST -1 was dry. <br /> <br />Three new surge ponds were being constructed in the YPM13 drainage of the North Pit, which drains into Pond <br />011A. One of the structures appeared to be completely excavated and the other two had been cleared of topsoil
