<br />X111. +COMIVIENTS -`COMPLIA'NCE <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 <br />inspection and the facts or evidence .supporting the enforcement action. <br />Sediment control maintenance work was noted to be necessary in two <br />locations. Further build-up of the SAE berm and excavation of the <br />sediment trap adjacent to the gully below the conveyor between the <br />slot storage facility and the rail loadout is necessary. Also, the <br />sediment control ditch on the west end of the prep plant bench, in <br />the vicinity of the small concrete reject rock bin is partially <br />blocked and needs to be maintained. <br />ocessina Wast <br />A considerable volume of reject material has accumulated in the <br />temporary stockpile on the prep plant bench. This material will <br />need to be hauled to the refuse area as necessary to ensure that <br />the permitted temporary stockpile capacity of 2500 tons is not <br />exceeded. <br />Implementation of TR-39 drainage and sediment control improvements <br />at the refuse areas has fallen behind schedule due to wet <br />conditions which have severely limited equipment operations at the <br />site since mid-October. The recent onset of colder temperatures <br />which has resulted in frozen ground should allow for equipment to <br />access the work locations. it is important that as much of the <br />work as possible be completed before spring thaw. <br />A slight depression remains in the area of RP-2/3 where saturated <br />waste was excavated a couple of years ago. The site needs to be <br />filled in with dry refuse, or further graded to ensure that no <br />ponding of water will occur in this location. <br />Several rock checks and sediment traps have been installed on the <br />lower segments of the RP-2/3 west side in-pit ditch. Certain <br />modifications appeared to be necessary to meet design <br />specifications. Dave Anderson indicated that the structures would <br />be modified as necessary, and that care would be taken to insure <br />that additional structures to be installed would be consistent with <br />the approved design. <br />The steep rocklined segment of the RP-4 eastside in-pit ditch has <br />experienced some downcutting and sidecutting of the channel. This <br />channel segment will need to be re-worked, and the existing cobble <br />will need to be replaced with angular riprap, with gravel <br />underliner. <br />
