8e1ow are comments on the inspection. The comments include discussion of observations made <br />during 4iae inspection. Comments •also describe any er+for~cement .actions taken during the <br />inspection and the facts or evidence supporting the enforcement action. <br />Road surfaces and drainage structures generally appeared to be in <br />good condition. Maintenance appeared to be needed in a few <br />locations, including the lower drop inlet in the median ditch <br />between the D portal access road and refuse haul road, and a couple <br />of the drop inlet structures in the vicinity of the junction of the <br />refuse haul road and the prep plant upper bench access road. The <br />drop inlet grates in these locations were partially blocked by ice <br />and sediment. <br />The first refuse haul road ditch outlet to the south of the County <br />Road 65 intersection needs to be somewhat better defined. <br />The inlet end of the <br />access road was partly <br />be removed. <br />Hydrologic Balance <br />eastern-most culvert along the East Portal <br />obstructed by a large rock, which needs to <br />NOV C-96-019 had been fully abated and was terminated during my <br />inspection on Dec. 18. At the time of my inspection, the Pond RP-1 <br />discharge culvert joint had been repaired and re-buried. The <br />operator indicated the work had been completed on December 2. Bill <br />Lepro, the professional engineer who certified the repair work in <br />his letter of December 10, stated that he had inspected the repairs <br />on December 3. <br />Pond RP-1 contained a small pool of water, with a thick cover of <br />ice at the time of the inspection. RP-2/3 and RP-4 were both <br />frozen over, with the ice surface approximately 1 foot below the <br />top of the riser at RP-4, and 2 feet below the top of the riser on <br />RP-2/3. RP-5 ice surface was approximately 4 feet below the level <br />of the open channel spillway. To ensure adequate storage capacity <br />in RP-2/3 and RP-4, both ponds should be pumped down further. <br />Additional capacity is available in both RP-1 and RP-5, if the <br />water to be pumped will not meet discharge limits. <br />Pond DP-1 was frozen over, but the primary discharge valve was open <br />and the pond was discharging clear water. Pond SS-1 ice surface <br />was just below the discharge elevation. Other sediment ponds in <br />the permit are were either dry, or contained minimal amounts of <br />water, and were iced over. <br />
