<br />Topsoil Replacement <br />Topsoil replacement (topsoil layer of approximately one-ft minimum) will occur <br />following regrading and scarification of the surface primarily in late summer and <br />fall. This procedure limits the time that topsoil is exposed prior to revegetation <br />and avoids moving topsoil when it is frozen or too wet. <br />Revegetation <br />Revegetation with predominantly native grassland will be undertaken. The <br />reclamation seed mix is shown in Table E-1. The seed mix for temporary cover <br />is provided in Table E-2. <br />Seeding Method <br />Seeding will be accomplished using either a seed drill properly equipped to meter <br />the native grasses of the mix, or using broadcast followed by harrowing or raking. <br />Seeding will be done in the fall after October 15` to facilitate successful <br />germination. Following seeding, the area will be covered with certified clean <br />straw at a rate of approximately two tons per acre. <br />Weed Management <br />The development of weeds will be closely monitored to ascertain the need for <br />control. Of greatest concern will be the development of Canada thistle (Cirsium <br />arvense), leafy spurge (Euphorbia esula), diffuse knapweed (Acosta diffusa), <br />z2 <br />
