III. COMMENTS -COMPLIANCE <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 />Coal Creek Channel <br />Work along the Coal Creek channel segment between the Upper Dip section culverts and the lower Haul Road 4 <br />crossing (large road fill with two large culverts) was discussed with Jim Stover. The upper end of the segment in <br />the immediate vicinity of the dip section road crossing, including the riprap bank segment adjacent to Pond 6, <br />has been properly restored. Large riprap has also been placed along the upper end of the side-cut erosion <br />segment on the bank adjacent to pond 10. Additional grading wrll be necessary along the segment downstream <br />of the riprap to eliminate the vertical incision along the entire segment of bank adjacent to pond 10. Additional <br />riprap placement may also be warranted, with the intent being to protect the bank adjacent to Pond 10, and <br />divert the force of the flow away from the Pond 10 bank. At the lower end of the channel reach; water had <br />backed up a considerable distance above the large culverts at the road crossing, and a significant quantity of <br />sediment had been deposited. Along this lower segment, the original channel capacity and depth had been <br />reduced. Sediment excavation and grading will be necessary to restore design capacity, depth, and <br />gradient along this lower, depositional segment. <br />The lower dip section crossing of Coal Creek, on the UTL haul road had been properly repaired. The culverts <br />had been cleared and erosion along the sides of the concrete structure and adjacent channel banks had been <br />filled, graded, and riprapped as appropriate. <br />Other Maintenance Items <br />A number of other items had been completed, and work was continuing on maintenance associated with both <br />the July 20 storm and the August 1 flooding of Coal Creek. <br />4 <br />
