<br />~nks and Gesso, LLC <br />Topsoiling <br />Topsoil, segregated during mining and maintained in stockpiles within the permitted <br />area, will be protected from erosion and maintained in a condition suitable for <br />reclamation. Topsoil stockpiles will be seeded with temporary cover, if they remain in <br />place for more than one growing season; and they will not be relocated until topsoil is to <br />be replaced on disturbed, but graded, areas. Topsoil will be placed evenly and <br />supplemented with soil amendments, as necessary, to restore growing media for an <br />effective, self-regenerating cover appropriate for a rangeland use. <br />Revegetation <br />Following replacement of topsoil, and preceding revegetation, any disturbed areas <br />located outside of the areas identified for future water storage, as well as the southern <br />part of the mining area to be reclaimed as rangeland, will be graded and scarified if <br />needed. Revegetation will utilize predominantly native grasses suitable for rangeland <br />use. Everist will analyze topsoil samples in advance of seeding operations and submit <br />these test results to the Natural Resources Conservation Service office for a specific <br />seed mix recommendation. Specific seed mixes are identified in Tables E-1, E-2, and E- <br />3. <br />Seeding will be accomplished using either a seed drill properly equipped to meter the <br />native grasses of the mix, or using broadcast seeding followed by harrowing or raking. <br />Seeding will be done after October 15' to facilitate successful germination. <br />The development of weeds will be closely monitored to ascertain the need for control. <br />Of greatest concern will be the development of Canada Thistle, Russian Thistle, <br />Mustard, Kosha, Field Bindweed, and possibly Rye. If any of these appear during the <br />first year after seeding, they will be controlled with mowing operations, at specific times. <br />The presence of annual and biennial weeds during the first few years after seeding is <br />normal and can be expected to diminish thereafter. The use of herbicides for weed <br />control should wait at least one year after seeding, to allow the native grasses to gain <br />stamina. Everist assumes responsibility for weed control on all areas of the site affected <br />by mining operations. <br />Lohmann Santl and Gravel Mine.DMG <br />L.G.
