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 />There are several small seeps which emanate from the lower portions <br />of Bench 2 and Bench 3. These seeps have been in existence for <br />several years, and are visually apparent due to surficial salt.. <br />crusts. Vegetation has been suppressed in the immediate vicinity ' <br />of the seeps due to saline conditions, there has been minor surface ~- <br />soil sloughage in the past, and there is minor rill erosion within <br />some of the seep areas. As generally is the case, the seeps were <br />saturated at the surface, but there was no actual flow at the time <br />of the inspection. No cracking or slumping of refuse material <br />indicative of mass instability has occurred within the seep areas <br />or other areas of the pile. A smalled quantity of water was <br />puddled at the outlet of Underdrain #l, within Pond 6, as typically <br />is the case. <br />There was no significant rilling or gullying on reclaimed benches, <br />and bench drains were properly maintained, with no significant <br />erosion or sediment accumulation. Southeast Collection Ditch (HH) <br />was in good condition, with minimal erosion or sediment <br />accumulation along its length. Northwest Collection Ditch (GG) was <br />in good condition along most of its length, but in one 45 foot <br />segment approximately halfway between Terrace Drain #2 and Terrace <br />Drain #3, the ditch was filled in with coaly sediment. Due to <br />topography in the immediate vicinity, any flow escaping the ditch <br />would have flowed parallel to the inside of the ditch for a short <br />distance, before re-entering the ditch further down the slope, <br />Sediment had been cleaned from the ditch to restore. the original <br />capacity upon follow-up inspection on August 8. Riprap replacement <br />in the ditch segment had not yet been completed, due to rainfall <br />which had interrupted the project. A backhoe was still on site and <br />the operator indicated the riprap would be replaced shortly. <br />Culverts along the SE Collection Ditch were in compliance with <br />permit specifications, and were properly maintained. <br />Vegetation is well established on the reclaimed slopes, with the <br />exception of the small areas of salt affected soils in the small <br />seep areas. Shrub density appears to be significantly lower on <br />CRDA-1 than on CRDA-2, with grass cover apparently somewhat higher. <br />There are no areas of excessive rilling or gullying. <br />RSRDA <br />The RSRDA was inspected on the morning of August 6. Weather was <br />partly cloudy with light rain the previous night. There has been <br />no disposal of refuse at this disposal location since the early <br />1980's, and no further disposal is proposed. Refuse outslopes have <br />
