III. COMMENTS - COMALIANCE <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 />melt water flowed across the light use road, causing or contributing to the soil movement and erosion on the <br />slope below the road. DSC0294 is a view of the flow path across the road (right center of photo). Road ditch <br />was apparently silted in and lower segment of Channel PM-4C was also apparently silted in and poorly defined. <br />DSC02985 is a close-up view of flow path across road surface, with gully headcut visible at the far edge of the <br />road (adjacent to hardhat in DSC02986). DSC02987 and DSC02988 show the short gully segment and the <br />trough shaped "slip" below, with deposition at the toe of the slope visible in DSC02988. DSC02989 is a different <br />perspective of the gully segment. Roy Karo has indicated that the 2" PVC pipe visible in the photo had been <br />placed a couple years previously to drain a wet area where a dozer had become bogged down. The pipe had <br />apparently been covered over by subsequent road construction, but the outlet was apparently exposed by <br />erosion this spring. DSC02990 is a view from the depositional area at the toe of the slope, back up toward the <br />slip feature. DSC02991 is of the primary depositional area {note the aspen trees knocked down by the slide). <br />Photos DSC02992 and DSC02993 were taken some distance downstream of the toe of the slide along the <br />ephemeral channel; DSC02992 looking upstream and DSC02993 looking downstream. <br />The ephemeral channel eventually empties into Sediment Pond 015, which was constructed to treat the small <br />areas of reclaimed disturbance that drain off the east facing slopes of the reclaimed Neck Pit area. <br />Roads <br />Active use roads and permanently reclaimed roads (which have been gravel surfaced) were in good condition, <br />although typical spring ditch maintenance is warranted in some locations, due to recent thaw and snowmelt. <br />Roads that have been reduced in width for postmine use, but not yet final surfaced were muddy, and in some <br />locations impassable. Significant road removal and final surfacing and stabilization work (cut and fill seeding) for <br />roads to be retained for the postmine land use will be conducted during the 2007 field season. "J" road reduction <br />grading has been largely finished, but final surfacing, as well as topsoiling and seeding of cut and fill of slopes is <br />yet to be done. <br />The reduced segment of "G" road, completed in 2006, looks quite good for the most part. Revegetated slopes <br />along the road appear stable. Vegetation is dominated by annuals in most areas, but seeded perennials are <br />present at reasonable densities, and should become the dominant cover within the next couple years. Patches <br />of Canada thistle and houndstongue are present in some areas and will need to be sprayed later in the <br />season. A segment of the cut slope road ditch west of Pond 005 had down-cut, and repair will be <br />necessary, along with rock lining or other appropriate stabilization measures. <br />Maintenance grading is needed along various road ditches along the lower "A" road and upper "MEHR" <br />road, including "A" Road ditch from the shop area down to the 006 drainage, and the "MEHR" ditch from <br />the Oil Well Road junction down to the first culvert inlet to the west, to clean out accumulated sediment. <br />Gravel was excavated from below the outlet of the MSHA berm culvert along the lower "MEHR" road <br />last fall, and piled up on the upstream side of the outlet. This gravel material needs to be properly <br />disposed of. <br />Hvdrolocic Balance <br />Snow melt runoff was largely over, but there was flow in the lower portions of several of the larger permanent <br />drainage channels. <br />Permanent Channels <br />Drainage channels that could be observed appeared to have held up relatively well to the spring runoff, although <br />there will likely be various locations where repairs will be necessary. Access was restricted due to muddy <br />conditions, and most channel segments not close to surfaced roads were not checked. <br />4 <br />
