Both primary and emergency spillways were clear of debris and functional. No <br />issues were observed with DP-1. The secondary ditch form the facility area to DP-1 was reestablished prior to the <br />previous inspection. The channel remains stable with no issues observed. The main ditch into DP-1 remains stable <br />and well armored with rip rap. No signs of erosion or cutting were found. <br /> <br />Both ponds PP-1 and PP-2 held water with no discharge. No issues were observed. <br /> <br />B-seam dewatering pump was not active at the time of the inspection. The six initial ponds held water and the <br />artificial wetlands were partially filled. No water has been pumped up to the Last Chance Pond and no water has <br />been discharged from the dewatering pond system up to the date of this inspection. No issues were observed. <br /> <br />Ponds RR-1, RRS-1, SS-1 and SS-2 were all dry. Embankments and spillways were stable. <br /> <br />Refuse Ponds 2/3 and 5 were dry, stable and with no issues observed. Pond RP-4 held water but with no discharge. <br />Spillways were clear and in working order. Embankments for all the refuse ponds were vegetated with no <br />slumping or stability issues. <br /> <br />The culvert below the access road to the Slot Storage has been partially crushed on the outlet side and is in need of <br />repair. <br /> <br />Ponds SS-1, SS-2, RR <br /> <br />PROCESSING WASTE/COAL MINE WASTE PILES Rule 4.10 and 4.11 <br />Drainage Control; Surface Stabilization; Placement: <br />Refuse spreading and compaction was occurring on Refuse Pile 5A at the time of the inspection. Lifts were <br />approximately six inches in depth. The winter stockpile remains in place. Compaction on Refuse Pile 2/3/4 <br />appears sufficient based upon driving on top of the pile. Both refuse piles have been constructed to allow runoff to <br />
