• III. 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 Mike Boulay and Dr. Jim Pendleton both of the Division of Minerals and Geology (DMG). The inspection was completed over the course of two days. The inspection occurred on the afternoon of July 9, 1997 and was completed on the morning of July 10, 1997. The primary focus of the inspection was a slope failure under and in the fill of the main hauVaccess road being constructed as part of the Sylvester Gulch Facilities (Permit Revision #07). Christine Johnston and Eric Mende of Mountain Coal Company accompanied [he DMG during all of the inspection. On July 9, 1997, Henry Barbe of MCC was present for a portion of the inspection. Philip Solseng, P.E. of Barr Engineering Company was also present on July 9th to aid in determining the potential cause of the slide and to discuss remedial measures that may be implemented. Day One Inspection (7/9/1997): Slides & Dama¢e At approximately 2:45 p.m., the inspection initiated at the site of the slide that occurred along a portion of the main hauVaccess road in Sylvester Gulch. Inspectors Pendleton and Boulay were accompanied by Christine Johnston and Eric Mende of MCC and Philip Solseng of Barr Engineering Company. The inspection began at the northern limit of the slide azea and proceeded to the south along the top of the fill material placed on the hauVaccess road. After investigating the entire width of the slide from on top of the fill, the inspection continued downslope to the toe of the slide adjacent to Sylvester Gulch. Dr. Pendleton, Mr. Mende and Mr. Solseng inspected the entire base of the slide. Dr. Pendleton's findings for the slide damaged areas are presented below in the following 8 paragraphs. Landslide -Main Access Road According to MCC, the landslide commenced on July 4[h between approximately stations 62+00 and 68+00 on the SGFA main access road. The road embankment had been partially constructed. A maximum of approximately 30 feet of fill had been placed on the slope west of the Sylvester Gulch channel. Following the slope failure, the toe of the embankment was approximately five feet from the channel in places. The highest pull apart crack measured approximately five feet across with approximately seven feet of vertical offset. The road is impassible. Eric Mende of Mountain Coal's environmental staff has been compiling daily visual measurements of crack growth. Eric's data show that the rate of downslope movement has slowed, but as of our visit, was continuing at approximately 1 foot per day. Some transverse cracking is apparent on the slope between the toe of the fill and the creek. No significant
