The Division will, as required by Rule 5.02.2(3)(b), investigate <br />this matter on -site. <br />PROCESSING WASTE /COAL MINE WASTE PILES — Rule 4.10 and 4.11 ❑ Drainage Control; Surface <br />Stabilization; Placement: <br />Gob was being placed on Gob Pile #2, on the west end of the third bench (between ditches F2 and F12) <br />and at the northern tip /upper bench. It appeared that water was impounded on the third bench, below recently <br />placed gob. Care must be taken in placing gob to ensure that drainage off of the pile is maintained. <br />The diversion ditch configuration approved under Minor Revision No. 132 had been implemented.
