The operator has performed a good deal of maintenance work on the ditches since the last inspection included cleaning the ditches and sumps and repairing and replacing straw bales. - The upland diversion ditch and perimeter ditch at the Hubbard Creek fan were stable and in good condition at the time of the inspection. Both ditches were clean and no erosional problems were noted in either ditch. Backtilling & Grading: -The backfilled Sanborn Creek portal appeared to be stable at the time of the inspection.

There was no water pooling on the pile and all of refuse has been spread and compacted on the pile. There is approximately 10 vertical feet left on the pile, based on the operator's recent survey and the survey stakes that have been placed in the ground.

No erosional problems were noted on the outslopes of the pile at the time of the inspection. - The II-West refuse pile was inaccessible due to the muddy conditions on the haul road at the time of the inspection. - The reclaimed East Yazd pile appeared to remain stable and well vegetated.
