A small depression was noted on the outer embankment of Pond 008A. <br />Depressions can allow water to pool and infiltrate the embankment, potentially compromising its <br />structural integrity. This is a very small depression right now, evident only because water was <br />puddled due to recent rains. Vegetation was sparse on the top of the embankment but much <br />better on both the inner and outer banks. <br />Maintenance is necessary in the SAE that includes topsoil pile #2. NECC excavated earthen <br />material and placed that material on the stream buffer zone boundary berm. This material should <br />be removed from the berm to ensure it does not slump into the stream buffer zone. <br />NECC recently installed a v-notch weir at the discharge point in the SAE by Pond 007. Silt fence <br />surrounding the discharge weir is in need of repair. This discharge point will now be NPDES <br />outfall #10 and will be sampled twice per month if discharges occur. <br />The following culverts were found to be in good condition: C-B, C-12A, C-14, C-21, C-39, and <br />C-49. <br />The following culverts were identified for maintenance: C-A (sediment, requires cleaning); C- <br />11A (on Map 13, not found in field), C-23 (designed at 30” but is actually 24”); C-45 (sediment, <br />requires cleaning); C-52 (mapped but does not exist); C-64 (clogged, needs immediate clean <br />out). <br />The following diversions were identified for maintenance: D-10A (sediment is accumulating and <br />pooling water); D-11 the SAE outlet structure east of DWDA #2 is down-cutting (additional rip <br />rap would be wise); D-28 (erosion below C-49, on-the-ground does not agree with Map 13); D- <br />39A (sediment is accumulating and should be cleaned), D-56 (sediment is accumulating and <br />pooling water in upper portion), D-61 through 63 (channel is small and should be reconstructed <br />to ensure adequate capacity). <br />Rule 4.06: Topsoil <br />The east end of topsoil stockpile #2 was recently graded and bermed but is not yet well- <br />vegetated. The material is contained and no loss of resource was noted. <br />The “soil storage area” south of the DCWP hosts two distinct piles: one vegetated topsoil <br />stockpile and one un-vegetated subsoil stockpile. The topsoil stockpile is well-vegetated, <br />marked, and bermed. The un-vegetated subsoil stockpile has coal material (coal fines to 2” <br />chunks) scattered on the surface. This is subsoil from the Bates portal development and will not <br />be used as topsoil. The end dump configuration at the top of this pile is impounding water. <br />NECC formerly used roof bolts and orange plastic fencing to exclude wildlife from this area. The <br />fencing has fallen down and the pool of water could pose a hazard to wildlife. <br />Rule 4.09: Excess Spoil and Development Waste <br />The Refuse Disposal Area (RDA) remains partially reclaimed and partially open to receive <br />additional material. The three lowest benches are reclaimed while the upper portion remains <br />open and is permitted to be built up above its current elevation. New material was on the top of <br />the pile, staged to be spread and compacted when dried. This material was likely generated from
