<br />f <br />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 <br />inspection anc( the facts or evidence supporting the enforcement action. <br />At the lower (southern} end of the relatively flat bench area, the <br />storm flow had split, with a portion of the flow pouring down the <br />steep fill outslope, and the remainder diverted down the main <br />access road. <br />Fruita #1 Fill Outslope <br />Storm flow was concentrated in the center portion of the steep fill <br />outslope, although evidence of overland flow was apparent across <br />much of the fill surface. A large "Y" shaped gully had been eroded <br />on the outslope, with the base of the "Y" near the bottom of the <br />fill, and the arms extending approximately halfway up the fill. <br />The main stem of the gully was approximately 15' deep, up to 50 <br />feet across, and approximately 40' long, with each tributary stem <br />of the gully l0' to 12' deep, up to 30' wide, and 60' to 70' in <br />length. Large quantities of mud and rock were deposited along the <br />length of the drainage between the base of the fill, and the <br />sediment pond several hundred yards to the south. <br />Main Access Road <br />The upper segment of the road, between the #1 bench and th~- <br />intersection of the road with the first side drainage showed <br />evidence of significant flow, with both the road surface and <br />ditches scoured. There was major sediment deposition across the <br />road at the side drainage location, approximately 300 feet down the <br />road from the mine bench. Ditches and culverts on both sides of <br />the road were completely buried by mud 2 to 5 feet deep, on either <br />side of the primary flow path down the center of the road. <br />Boulders up to 5 or 6 feet in diameter had also been deposited <br />along this segment. A portion of the flow spilled over the road <br />embankment at this location, and eroded a gully 2-5 feet deep by 3- <br />5 feet wide, extending to the base of the fill slope. The road <br />berm had also been breached approximately 150 further down the <br />road, with similar outslope erosion. From this point down the road <br />to the sediment pond location, the road surface was scoured and the <br />ditches entrenched. <br />Sediment Pond <br />Flow down the inside road ditch was diverted to the main drainage <br />below the sediment pond embankment, with a debris fan 60'x100'x <br />
