1 <br />' EXHIBIT E <br />' Reclamation Plan <br />Stocks Clay Mine <br />1 Upon completion of mining activities, the stockpiled spoils of the overbearing <br />' sandstone strata will be replaced and graded to approximate the original contours <br /> of the area. The scarcity of topsoil on the lease prior to initiation of mining <br />' activities precludes its reclamation to original conditions. The great amount of <br />' sandstone underlying only 2-4" of topsoil would create a porosity condition quickly <br />draining any naturally occuring moisture from the surface 4 feet of ground. To <br />' make optimal use cf the available topsoil, topsoil will be replaced only in areas <br />where it is most likely to support plant growth and revegetation, then furrowed <br />and broadcast seeded at a rate of 80 seeds/sq. ft. with native grass species to <br />approximate the prior existing vegetational species diversity and densities (see <br />table 1). <br />Root-balled stock nurses°y tree species native to the mine site (see table 1) <br />will be planted in approximate ratios that existed prior to mining at a rate of 50 <br />seedlings/acre. Because of the altered soil horizons and the resultant soil <br />permeability, available ground water will be significantly lower in the strata than <br />prior to reclamation; consequently, a low percentage of the seedlings are expected <br />' to survive to maturity. <br />Based on field surveys of undisturbed portions of the lease area adjacent to <br />' the mine it is anticipated that a seedling mixture of 40% Blue Grama, 20% Legume <br />species, 40% k'heatgrass species will be used. Other native grass species present on <br />the site are not commercially available as seed. Should data become available <br />indicating edaphic conditions more appropriate for other species of native grasses, <br />modifications of species types and ratios in the seeding mixture may be implemented. <br /> <br />
