<br />5) (cont.) <br />permit application package. <br /> <br />P&M understands that vegetative cover standards (47% for non- <br />topsoiled areas and 90% for topsoiled areas) for performance bond <br />release for all reclaimed areas must be met as described in the <br />approved permit application (Section 4.4, Revegetation Plan). To <br />ensure this, both impoundment sideslopes with sparsely vegetated <br />areas will receive augmentive seedings with the approved permanent <br />seed mixes, and shorelines void of vegetation will also be <br />interseeded with the approved riparian seed mix. <br />6) Rule 2.06.8(3)(b)(i) requires "Mapping of unconsolldated <br />streambed deposits holding streams including, but not limited to, geologic <br />maps of unconsolidated deposits, maps of streams..., topography showing <br />local and regional terrace levels, and topography o/ terraces, flood plains <br />and channels showing surface drainage patterns." Please provide a map on <br />a scale of 1 " = 100' showing the above listed features of Oak Creek in the <br />area for which declassification is proposed. The mapped area should <br />include lands 200' north and south beyond the area. Please include the <br />depth and aerial extent of all deposits, including coal lines and refuse <br />deposits from previous mining disturbances. <br />A field survey was conducted July 14, 1993 by P8M staff beginning <br />200' north of, and concluding 200' south of the permit boundaries <br />along the Oak Creek as recommended by DMG. No terracing is evident <br />through and around the declassification area as most of the area has <br />been at one time or another, disturbed by constructions of Highway <br />131, County Road 179, Denver & Rio Grande Western railroad and <br />mining activities. <br />Exhibit 4.6-10, "Oak Creek -Alluvial Valley Floor, Declassification <br />Area, Land Use/Disturbance Map", contains locations of the Oak <br />Creek channel, the extents of identified refuse deposits from <br />previous mining disturbances and the existing public transportation <br />systems (e.g., Highway 131, County Road 179 and Denver 8 Rio <br />Grande Western railroad, etc.). <br />
