This inspection report was <br />written by Todd Jesse of the Division. The aerial photographs were taken by Brock Bowles of the Division. The <br />weather was clear, and the ground conditions were partially snow covered. <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 /> There are three ponds located in the main facilities area: the DP-1 Pond, the PP-1 Pond and the PP-2 Pond. <br />The DP-1 pond was frozen at the time of inspection. The embankments appear stable with vegetative cover. There <br />were no erosional concerns identified. The PP-2 Pond was partially frozen. The embankment was stable with no <br />erosional features identified. The outlet structure was in good condition with no vegetation obscuring the outlet. <br />The PP-1 Pond is located on the middle bench of the facilities area. The pond was covered by processing plant <br />structures during the areal inspection. (Photo 1) <br />The B Seam Dewatering System No. 1 was active during the inspection. Cells were impounding water and the <br />lower cells were frozen and snow covered. Embankments of the cells were stable with no erosional featured noted. <br />The Last Chance Pond appears to be at the approximate level of the discharge. (Photo 2) <br />The B Seam Dewatering System No. 2 is located to the east of the Slot Storage. The system was inactive during <br />the inspection. The first cell was snow covered with no indications of water being present. The main cell was <br />holding water below the level of discharge. The water was frozen and snow covered. The embankments of the <br />pond were stable with no indications of erosion. (Photo 3) <br />Two ponds, SS-1 and SS-2, are located to the north of the Slot Storage facility. Both ponds appear dry at the time <br />of inspection. The embankments were partially snow covered, but appeared stable. There were no erosional <br />features identified. The outlets of the ponds were clear of debris. (Photo 4)
