Weather conditions at the time of the inspection <br />were clear; ground conditions appeared to be dry. <br />The mine is actively producing coal from the B seam west of Terror Creek, although it appeared that a longwall <br />move might still be underway, based on the coal stockpile levels. Coal refuse was being placed in Gob Pile #3; <br />grading and compaction were underway at Gob Piles #2 and #3. <br />HYDROLOGIC BALANCE -Rule 4.05 <br />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; <br />Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; Surface Water Monitoring 4.05.13; <br />Drainage —Acid and Toxic Materials 4.05.8; Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br />• All of the sediment ponds held water.
