The areas disturbed by the each phase of construction, including the topsoil <br />stockpile, coverfill stockpile, road fill, berms, pond slopes and diversion ditches that <br />are not riprapped, will be promptly seeded with the stabilization seed mix. The <br />components of the stabilization seed mix are listed in Volume I, Section 2.O5A,(2)(e). <br />A berm will be constructed around the topsoil stockpile to contain any topsoil that <br />may erode prior to the establishment of stabilizing vegetation. A straw bale or short <br />silt fence will be installed at the low point(s) in the berm to relieve accumulated run- <br />off. <br />When the gob pile is filled to capacity, the top of the fill will be graded 2% to 5% to the <br />back side of the pile (north) to promote adequate drainage. Drainage from the top of <br />the fill will not be directed over the outslopes of the fill. When each new bench is <br />constructed, the rough construction face below that point will be completed by <br />grading it to its final configuration. Benches will be graded to the inside at 5% and <br />graded to drain to the sides at 1.5% - 5 %. <br />Final reclamation will include completion of the cover material including topsoil, haul <br />road reclamation and completion of the permanent diversion and collection ditches. <br />Revegetation will be in accordance with Volume I, Section 2.05.4. <br />The seed mixture(s) will be hydroseeded or broadcast seeded. Seedbed preparation <br />for all disturbed areas shall be accomplished by one of two methods. The first <br />method will consist of extensive roughening by track hoe gouging (pocking). <br />Extensive roughening provides for increased moisture retention and favorable micro <br />sites for plant establishment. The first bench on coal mine waste disposal area <br />number 2 may not be extensively roughened since it was covered prior to the <br />roughening requirement being incorporated into the plan. The second method will <br />consist of ripping the coverfill, then placing the required depth of topsoil. The topsoil <br />will then be furrowed along the contour to retain moisture and curtail rill and gully <br />formation. <br />All seeded areas will be mulched with certified weed free grass hay or straw. <br />Approximately two tons of mulch will be used on each acre seeded. Straw or hay will <br />be anchored using a tackifier, netting, or a tackifier mixed with wood or wood /paper <br />fiber. The tackifier will be applied in accordance with manufacture's specifications <br />with consideration of the type and quantity of mulch applied, slope, soil conditions <br />and other applicable factors. <br />MR -161 -16- 09114 <br />
