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 Kent Gorham of the Colorado Division of Minerals and Geology (DMG). The weather was warm and ground conditions were generally dry with some muddy areas due to recent episodes weeks of rain and snow. Areas were accessible by foot and vehicle. Bobby Steele represented Lorencito Coal Company (LCC) during the inspection. Signs and Markers Two permit boundary markers were noted lying on the ground on the east side of the road about 100 feet after crossing the bridge over the Purgatoire River. These signs should be re- established in their proper locations. The mine identification sign was found in compliance with Rule 4.02. Roads Mr. Steele has been working on the permanent road where it crosses the disturbed area. One low spot in the road was noted between the 3'd and 4th culvert after entering the disturbed area from the east. A relief drain and ditch directing flow to the west will be constructed to promote surface drainage for this section of road. The light use road to pond 8 has a significant amount of rockfall from the cut slope littering the road. This rock should be cleared and used for a downdrain to route drainage into the canyon bottom from the road. The road should also be graded down to the pond to allow vehicle access. Hydrologic Balance High water marks on the banks of Lorencito Creek indicate the creek was significantly higher during the last week or so due to snowmelt and runoff. Disturbed area containment ditches were traversed and found in good condition with a minimal amount of sedimentation given the significant precipitation. LCC should install extra straw bales at the topsoil pile SAE on the east side of the disturbed area. Some ditch cleanout on ditch D75 between Fill 7 and Fill 9 is also necessary. Wier boxes to measure flow at each pond outtall should also be checked and leveled to ensure accurate flow readings in the event of discharge. The silt fence east of the Lorencito haul road should also be replaced or re-positioned due to sediment build-up. All sediment ponds at the site held water but none had discharged as a result of recent wet weather. All embankments and spillways appeared in good condition.
