See the DRMS availability of records <br />list attached. <br />: HYDROLOGIC BALANCE <br />Ponds inspected include the 004, 003, POCOCO Pond, and Pond 002. All ponds were discharging at the time of <br />the inspection. All ponds were stable with the exception of the following: <br />- A modified trash guard was installed at the Pond 004 outlet. The guard was comprised of two stakes - 3" apart. <br />This guard would prevent clogging of the outlet spillway of the pond. The current design identifies a screened <br />cage as the non- clogging device. <br />- Pond 004 embankments displayed two live willow trees growing at the toe of the embankment. The largest tree <br />was -15' tall, -4" diameter, -10' of foliage cover, and was -20' from the crest of the dam. <br />- Animal burrows are evident in the embankments of Ponds 003 and POCOCO. <br />All ditches and culverts inspected were stable and in compliance with the exception of the following: <br />-The unidentified culvert located perpendicular and -10 ft from culvert 29A will need to be addresses. Scott <br />Cowman stated that the culvert was installed by the land owner to allow access to a ranch road. This culvert will <br />need to be designed to ensure that its 12" diameter will be adequate allow drainage or will need to be replaced <br />with an adequate size and included in the Sage Creek permit or removed. <br />- Culverts 31A, A8, 13A and 53A are damaged. <br />: GENERAL MINE PLAN COMPLIANCE <br />This was a complete inspection of the Peabody Sage Creek Mine conducted by Jason Musick of CDRMS.
