2 • • <br />degasification borehole, and two ventilation shaft #3 boreholes. Being an existing road, MCC did <br />not "alter a natural drainageway for light-use road construction", nor did MCC "locate" this light- <br />use road in an intermittent or perennial stream. The road was already there. Thus, MCC <br />complied with Rules 4.03.3(1)(a), 4.03.3(2)(b) and 4.03.3(4)(d). (Also note that Sylvester Gulch <br />is an ephemeral stream.) <br />Second, berms are not only constructed and utilized to comply with MSHA safety concerns, but <br />are also an integral part of MCC's drainage and sediment control systems. The berms contain and <br />direct flows from the road similarly to some installations of silt fence. The silt fence along the <br />berm was actually a duplicative measure in this case, as the silt fence or the berm would provide <br />the necessary drainage control. The berm was not constructed in the stream channel as alleged, <br />but some soil and rock had rolled from the berm in a couple of locations. At the time this <br />inspection concern was identified, work was immediately initiated to pull back the berm material <br />and to reset the redundant silt fence. This work was being completed before the end of the <br />inspection. Also, recognizing the magnitude of the ez_nhwork activities within close proximity to <br />the stream channels, and the realistic potential for maintenance of literally miles of silt fence that <br />had been installed to be problem-free, MCC constructed additional (and redundant) drainage and <br />sediment control measures. In more than one location downstream of this azea, and within the <br />permit area, straw bale filters had been constructed and have been a very effective measure to <br />minimize sedimentation, prevent additional contributions of suspended solids, and to minimize <br />disturbance to the prevailing hydrologic balance outsede the permit area, in compliance with rules <br />4.03.3(1)(b), 4.03.3(2(d), 4.05.1(1), 4.05.5(1)(a), and 4.05.5(1)(c). <br />Third, MCC respectfully disagrees with the Division inspector's representation that these few <br />azeas of soil material and rock actually "impeded" (i.e., "obstructed" or "blocked") the flow of <br />this upper tributary of Sylvester Gulch, and that streamflow "appeared silty and was clearly <br />impacted" by this material. Flow in the channel was continuing unimpeded. This portion of the <br />tributary is not ahigh-gradient smooth-channeled area, so minor pooling occurs naturally along <br />the stream. In many locations along Sylvester Gulch, the channel is deeply incised, indicating high <br />natural erosion. MCC's representative had observed and pointed out to the inspector visibly cleaz <br />flows across grass-lined portions of the chazmel just downstream, and areas where flows were <br />exposed to naturally-eroded soils in this small channel. Certainly any such occurrence would be <br />nearly indistinguishable from natural conditions, as silty sediments have historically been carried in <br />the Sylvester Gulch stream, as evidenced by several naturally-occurring deltas downstream that <br />currently support wetland and riparian vegetation, as well as the rocks, boulders and soil materials <br />that have rolled down due to natural, geomorphologic activity. MCC has had extensive <br />experience in the visual assessment and sampling of NPDES total suspended solids (TSS) <br />limitations in sediment ponds, and have found that water that appears silty can be quite low in <br />TSS. Since no water sampling was done at the time of the inspection and no comparison was <br />made with natural, baseline conditions, it is difficult to conclude that significant siltation or <br />erosion, if any, occurred. <br />Finally, the construction of subsoil berms along temporary drill site roads, such as this road -- by <br />windrowing topsoil from constructed roads and then subsoil on top of that topsoil -- has proven <br />to be a very effective and disturbance-minimizing construction technique. MCC has utilized this <br />type of construction (where subsoil temporarily covers topsoil) for many years, and reclamation of <br />
