RULE 2 PERMITS <br />With regard to out of pit road embankments, where possible, road cut slopes will be reduced from 1:1 to <br />3h:ly, retopsoiled, seeded, and mulched. Cut and fill slopes will likely be left in a roughened condition <br />during construction, and then topsoiled, mulched and seeded post construction. Please refer to the <br />construction notes on Map 25E Sheet 3 of 4 for additional details regarding stabilization methods. The <br />seed mixture to be utilized for road cut outslope stabilization can be observed in Section 4.03.2 of this <br />application. Species were chosen to ensure rapid establishment and sediment control. <br />Upon the completion of all coal mining and reclamation operations by Colowyo in the Collom Area, the <br />office, shop, coal crushing facilities and other related surface facilities will be removed and the sites <br />reclaimed according to the grading, topsoil and revegetation procedures set forth in this plan, providing <br />there are no continuing beneficial uses for these structures. <br />Reclaimed areas will be appropriately fenced, if necessary, to manage grazing or browsing by livestock or <br />wildlife. With regard to shrub establishment areas, the design is to provide sufficient seed for the <br />development of more than adequate populations. If it is determined that marginal populations evolve and <br />warrant protection, or excessive damage (severe hedging) to those populations is noted, those areas of <br />sufficient size (e.g., 10 acres and larger) or sufficiently proximal to each other, may be fenced with elk - <br />proof fencing at the discretion of Colowyo's reclamation coordinator. This practice would occur to <br />ensure that reclamation would meet the established success criteria. <br />Planting and Seeding Methods <br />Planting and seeding methods will vary depending on degree of slopes, reapplied topsoil depth, new <br />techniques, targeted community, etc.; however, the same planting sequence will be used in most cases. <br />Seeding will occur during the Fall, immediately prior to the average first permanent snowfall event <br />(typically mid to late October). If seeding cannot be completed prior to seasonally permanent snowfall, <br />"mop -up" broadcast seeding may occur in the Spring as soon as ground conditions allow. Components of <br />the proposed seedmixes that would normally be applied via drill seeder will be applied at double the <br />seeding rate identified on the seed mix tables for these "mop -up" efforts and in cases where a drill seeder <br />can't be used safely to apply the mixes. <br />Following seedbed preparation, grassland targeted areas will be drill seeded with a heavy duty rangeland <br />drill with depth bands using the perennial mixture as shown on Volume 15, Table 2.05-7, Reclamation <br />Seed Mixture - Grassland. At times, broadcast seeding may be required on steeper areas, wet areas, very <br />rocky areas, or simply on areas that were missed by the drill seeding equipment. Broadcasting can be <br />used in conjunction with the drill seeding equipment to broadcast a portion of this mix as indicated on <br />Volume 15, Table 2.05-7. A very light "tine harrow" or similar equipment may be dragged behind to <br />facilitate a light cover of soil (-1/16 inch) over the broadcast seed. In this manner, the small seed for <br />species such as fescue, yarrow, and sagebrush will be placed in a more optimal manner for emergence. <br />This procedure (where the broadcaster is mounted on the seed drill) will facilitate a "one -pass" seeding <br />procedure. The utilization of a Truax/Trillion/Brillion drill would also facilitate a one -pass option. <br />Following seedbed preparation, sagebrush steppe targeted areas will be seeded with one of three scenarios <br />using the perennial mixture as shown on Volume 15, Table 2.05-9, Reclamation Seed Mixture — <br />Sagebrush Steppe. The first scenario would be identical to grassland targeted areas whereby a heavy duty <br />rangeland drill with depth bands would be used for taxa to be drill seeded along with a mounted <br />broadcaster and light tine harrow (for those taxa indicated for broadcast seeding). This process would <br />facilitate a "one -pass" seeding procedure. The second scenario would be separation of the drill seeding <br />and broadcast equipment that would require a "two -pass" seeding procedure. <br />Collom — Rule 2, Page 96 Revision Date: 12/30/16 <br />Revision No.: TR -108 <br />
