//L 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, and Rozellyn Hall 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 methane drainage well (MDW) sites in panels E-1 and E-2. This is the first inspection in 2010 during which these MDWs have been fully accessible by vehicle, as road clearing at the higher elevations of the mine could not begin before May 1 due to USFS restrictions. 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 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 Ditches next to roads appeared in good repair. No discharge was occurring at the underground mine water pumping site in Sylvester Gulch(CDPS outfall 017). Middle Flume on Dry Fork of Minnesota Creek was in good condition. The operator has recently removed a beaver dam from the site. Flow through the flume was around one foot deep. Beaver dams cause flow in much of Dry Fork to be spread across the valley bottom rather than being confined to a well-defined channel. 3
