<br />INSPECTION REPORT - Page 4 <br />File No. 80-224 <br />Date: May 8-9, 1985 <br />2. A stripped buffer should separate the active highwall face from the <br />undisturbed land towards which the highwall is progressing. This will <br />reduce the amount of topsoil lost through handling processes. Please <br />implement this method in the future. <br />3. According to the Reclamation Plan, "the topsoil stockpile will be <br />seeded by hand with sweet clover and perennial rye to avoid erosion." <br />Please implement this commitment. This constitutes a possible violation <br />of the approved permit provisions. <br />4. The estimated topsoil volume stockpile is approximately 3,600 cy. <br />The Reclamation Plan states that approximately 17,000 cy of topsoil will <br />be in storage. Please delineate the acreages from which, 1) topsoil WAS <br />stripped, and 2) topsoil has yet to be salvaged. <br />5. On-site solid-waste is not, but should be, addressed in the McKenzie <br />Pit Permit. <br />a. Asphalt and concrete dumping on the northern boundary of the permit <br />area should cease. <br />b. Disposal Off-site, or elsewhere on-site, preferably buried within <br />the backfill material, should be designated. Please provide the <br />solid-waste disposal plan. Please revise Rule 6.1(a)(d). <br />6. Please address the handling of the junk on-site as part of the <br />reclamation plan. <br />7. A functional drainage system should be designed such that off-site <br />flow is controlled, and erosion minimized. <br />8. Erosional features of the northern slope require correction. <br />Backfilling, sloping to Permit provisions, and reseeding, where <br />necessary, may be the solution. Perhaps an engineer could devise a <br />suitable plan. <br />A proper drainage control system will reduce the possibility of further <br />erosion. It should be designed and implemented prior to slope erosion <br />correction. <br />9. The leak in the asphalt-plant retort should be repaired immediately <br />to abate further contamination of the irrigation ditch into which <br />oil-laden overland flow may deposit. <br />10. The broken underground irrigaton pipe should be mended. Although <br />it is not the operator's propery, the water issuing from the broken pipe <br />is causing disturbance to the prevailing hydrologic balance and off-site <br />damage, each of which constitutes a (possible) violation of the Minerals <br />Rules and Regulations. (see Rule 6.2 artd 6.1(b), respectively). <br />
