COMMENTS
This was a complete inspection conducted by Janet Binns of CDRMS. Scott Cowman of Seneca Coal Company
accompanied the inspector and represented the operator. The weather was foggy and raining. The main access
road from RCR No. 27 was muddy and impassible. The area has received several consecutive days of rain.
Weather conditions made access to several areas of the permit impossible. The mine is a reclaimed surface mine.
As such, no mine personnel are on the mine site and road ways are maintained for limted access only.
AVAILABILITY OF RECORDS — Rule 5.02.4(1):
Records were verified in the Peabody Sage Creek office. Records were found to be retrievable and up to
date.
HYDROLOGIC BALANCE - Rule 4.05
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;
Diversions 4.05.4; Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18:
Pond 10 was inaccessible.
Pond 14 was holding a pool of water but was below the discharge elevation. YPM 3-2A, YPM 3-2 and YPM-14
drainage had considerable runoff flow. All three drainages were holding up well. Gabions were functioning well.
Water flow was pooling on the upstream side and sediment was dropping out, while water flow continued through
the gabions. Runoff was not short cutting, or side cutting the rip rapped drainages.
The runoff noted in the April 2015 inspection report that is starting to gully immediately west of SP06-3 continues
to downcut. This flow is caught in YPM3-2 and is controlled by Pond 14. The Division has concerns about the
runoff on the slope north of SP06-3. Runoff from this slope area continues to rill and concentrate flow. The
operator was evaluating directing runoff into the permanent drainage further to the east, at approximately the
northern point of SP06-3. This would minimize downcutting of the light -use roadway adjacent to YPM3-2.
