M. COMMENTS - COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. This was a partial inspection conducted by Tom Kaldenbach of DRMS. Ryan Sweetwood represented the operator. Selected photographs taken during the inspection are attached to the end of this report. With the operator's consent, this report was issued from the Denver office of DRMS. The longwall was active near the west end of E-Seam Panel 1. The ground was dry. The inspection focused on the following areas: the future location of the buttress at the toe of Refuse Pile Expansion East (RPEE), surface facilities areas in Sylvester Gulch, reclaimed methane drainage well (MDW) sites along West Flat Iron Road in E '/2 Section 27, active construction areas on and near the Lower Refuse Pile, and reclaimed areas in Lone Pine Gulch. Signs and Markers Topsoil markers were properly displayed in all areas inspected, including MDW pads. The disturbed area perimeter of MDW pads and their roads are not marked by signs. The perimeter of the area disturbed at each pad is readily recognized by a cut-slope on the uphill side of the pad and an earthen berm and its outslope of downcast material on the downhill side of the pad. A sign on each wellhead marks the identifying number of the MDW, and the perimeter of the disturbed area of each pad is recognized by the area of disturbed ground that is within about a 200-foot radius of the wellhead. The disturbed area perimeter of the MDW roads is readily identified by the road right-of-way. DRMS is reviewing recently submitted Minor Revision 366 for the applicable requirements for marking the areas affected by surface operations at MDW sites and MDW roads (Rule 4.02). Roads Road surfaces were well-maintained in Sylvester Gulch, the Sylvester Gulch Road Extension, and on roads leading to methane drainage well sites. No signs of excessive erosion were found on road embankments. Hydrologic Balance Sediment was being removed from Freshwater pond#2 (see photo). Pond 002 contained a pool of water(see photo), but was not discharging(discharge is controlled by a gate valve). Construction has been completed in the last few months on the following structures approved in TR- 119: new pond MB-5E, a 48-inch diameter HDPE pipe that was buried and will feed runoff to pond MB-5E, a bridge across the North Fork that provides access to pond MB-5E, and a concrete-lined sediment sump next to the construction site of stacktube ST-5 (site of recently removed pond MB-2R). Pond MB-5E was built at the same location as former pond MB-5 (which was the Bear Mine pond), and replaces pond MB-2R which recently was removed. Pond MB-1 will be converted to freshwater 3
