III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations made <br />during the inspection. Comments also describe any enforcement actions taken during the inspection <br />and the facts or evidence supporting the enforcement action. <br />This was a partial inspection of the Bear Mine conducted by Mike Boulay of the DMG on <br />February 10, 1997. During the inspection, other DMG personnel including Michael Long, Dr. <br />Tim Pendleton, Susan McCannon, David Berry, and Bruce Stover were on site to investigate the <br />landslide that occurred west of the Edwards Mine portal area on November 15, 1997. Jim Stover <br />representing Bear Coal Company was present during the entire inspection. This report presents <br />the findings of the partial inspection conducted by Mike Boulay. <br />Hydrolo¢ic Balance <br />The majority of the site was snow covered at the time of the inspection. The site pond contained <br />water but was not discharging. Ditches that were not snow covered, were found to be well <br />maintained and generally in good condition site wide. <br />The spring that discharges immediately west of the slide mass (Edwards Portal Spring) was <br />inspected. There were no significant changes in the appearance of the discharge since the last <br />inspection. It did appear that some of the discharging water was not being fully captured by the 4 <br />inch flexible pipe that was installed to direct the water to the North Fork of the Gunnison River. <br />Discharge was noted flowing around and beneath the pipe in the vicinity of the former coal <br />stockpile pad. Please redirect the flow at the source of the spring or take other measures as <br />needed to ensure that the discharge is fully conveyed to the pipe, and that any discharge to the <br />North Fork of the Gunnison River is in full compliance with all applicable standards. <br />The end of pipe discharge at the river appeared to be flowing at approximately the same rate as at <br />the time of the last inspection. The discharge had a distinct yellowish color and was warm to the <br />touch. In the immediate vicinity of the discharge pipe, upgradient and in the direction of the <br />former coal stockpile pad, it appeared that water was seeping out of the ground on either side of <br />the pipe. The origin of this water was not positively identified. It appears that a portion of the <br />water from the spring may be flowing through the alluvium beneath the coal pad and discharging <br />to the river. <br />Slides and Damage <br />Dr. Jim Pendleton and Bruce Stover in the company of Michael Long, Susan McCannon, David <br />Berry and Mike Boulay performed an examination of the landslide and surrounding terrain. The <br />focus of the examination was primarily on the geotechnical characterization of the landslide and <br />the geomorphology of the hillslope. Detailed findings of the landslide investigation are <br />forthcoming pending further study by the DMG. <br />
