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 Tom Kaldenbach of the Colorado Division of Minerals and Geology. No one else was present. The ground was dry. DMG completed reclamation on this site in May 1993. HYDROLOGIC BALANCE There are no ponds or ditches on the site. Good vegetative cover appears to be controlling erosion throughout the site. No gully or rill problems were found, even on the steepest slopes on the site. There were no sediment fans or deltas. Positive drainage was well-established throughout the site. The site appears to be no more susceptible to erosion than surrounding undisturbed lands. There were no signs of seepage below the reclaimed portals. No off-site hydrologic impacts were apparent in Hay Gulch downhill from the disturbed area. SLIDES AND DAMAGE The site is located on anorthwest-facing hillslope. Regional geologic maps show this is the updip edge of the Menefee Formation which dips approximately 3 degrees south (into the hill). There is no fill material on this slope. The slope appeared stable. RECLAMATION SUCCESS Reclamation appeared successful throughout the site, with one exception. An open hole was found approximately 10 ft. uphill from the east DMG marker (see attached photos). This is in the area of the reclaimed east portal. The hole was one foot in diameter extending to at least 5 ft. deep, and appeared to continue deeper to an unknown depth with a 4-inch diameter. There seemed to be a faint sound of drafting air in the hole, but this was not certain. There were no other signs of ground instability around the hole. There were no signs of animal or human activity near the hole.
