2.05.3 <br />On December 31, 2014, the Applicant had an aerial survey of the gob piles <br />performed. The contours generated by this survey were compared to the <br />final projected contours of the gob piles. The resulting calculation <br />demonstrated there are approximately 1,723,000 tons of remaining storage in <br />the gob piles. To be conservative, this number was reduced by 10% for a <br />resulting capacity of 1,550,000 tons.
