<br />• therefore, the seeding will be completed just prior to the season <br />when the probability of moisture is at its greatest. <br />All road access road embankments will be stabilized by seeding the <br />roughened surface immediately after construction and regrading. <br />For long-term stability, the embankments or cut slopes will be <br />seeded with a mixture of the perennial grasses shown in Table 2, <br />Proposed Seed Mixture - Cuts and Fill Slopes. These areas will be <br />mechanically stabilized by surface treatment and mulch, if <br />necessary, with approximately 2,000 pounds of native grass hay or <br />straw mulch per acre. <br />Planting and Seedin Methods <br />Following the preparation of the seedbed, the facilities area will <br />be seeded with a perennial mixture as shown in Table 1, Proposed <br />Seed Mixture. On steeper slopes, seed will be broadcast seeded at <br />twice the drill seed rate. Dependent on availability of equipment <br />and labor, hydroseeding methods may be utilized. On level areas, <br />all seed will be drill seeded with a heavy duty rangeland drill <br />• pulled by a rubber tired farm tractor or small crawler dozer. Seed <br />covering on areas broadcast seeded will be accomplished by chisel <br />plowing or harrowing where possible. <br />Removal of Surface Structures, Embankments, and Tmaoundments <br />All embankments and impoundments will be completely removed and <br />reclaimed after the termination of the loadout activities. The <br />sedimentation pond and diversions will not be removed until the <br />affected area has been restored and vegetation reestablished such <br />that the quality of the surface runoff meets the applicable NPDES <br />effluent requirements. Interim drainage and sediment control <br />measures will be implemented during this time. The plan for <br />interim drainage and sediment control is presented on Map 10A, <br />Interim Drainage and Sediment Control. Upon removal of the <br />sediment pond and diversion ditches, the small areas affected by <br />the pond and diversions will be regraded and revegetated as <br />described in the grading and revegetation sections. <br />• 2.05-11 <br />Rev. 05-27-93 <br />
