Chapter II <br />topsoil is hauled and stored in topsoil stockpiles <br />• _ approved by CMLRD; <br />topsoil stockpiles are posted with TOPSOIL signs; <br />- topsoil stockpiles are seeded with a temporary <br />cover crop to protect them from wind and water <br />erosion; <br />- when necessary, topsoil stockpiles are protected by <br />perimeter diversion ditches designed to convey the <br />peak flow from the 10 year/24 hour storm event. <br />No topsoil will be salvaged when snow is on the ground. <br />c. Topsoil - Sutey. <br />The main topsoil storage area is situated northwest of the Sutey pile. A berm and <br />perimeter ditch, 8 to 10 feet from the toe, runs along the lower end of the topsoil <br />stockpile. <br />Topsoil storage at the conclusion of Phase I of the Sutey pileexpansion (Summer, <br />1987) was estimated at 45,360 + cubic yards. The estimated additional topsoil <br />recovery from topsoil salvage as the refuse pile expands through Phase III totals <br />38,890 cubic yards of material. <br />• Technical Revision 8, approved August 27, 1987 for expansion of the Sutey refuse <br />pile, allows two additional topsoil storage areas at the site. <br />d. Topsoil - Adit/Rock Tunnel. <br />A technical revision was approved Feb. 10, 1987 (TR-7) for further expansion of the <br />Adit/Rock Tunnel yard area by an additional 1.7 acres (in addition to the .9 acre <br />expansion approved in TR-6, Nov. 5, 1986), and the Adit/Rock Tunnel yard <br />expansion was completed in 1987. <br />In the expansion, the existing topsoil pile (1480 cu. yds.) which had been located in <br />the designated fill area was moved and an additional 2,000 yards of salvaged topsoil <br />went to the storage pile. <br />As noted in Chapter G, Soils Resource Information, in areas disturbed in connection <br />with tunnel face-up work, soil horizons have been too thin to support vegetative <br />growth individually, and plant growth will depend on combined soil horizons. <br />Construction of two additional sediment ponds is the only additional surface <br />disturbance anticipated in the term of the permit. A topsoil pile is situated at the <br />location of the tunnel ponds. <br /> <br />35 <br />
