TR-07 RECLAMATION PLAN <br /> Appropriate seeding times: Although in theory seeding can be done at anytime, generally <br /> seeding during specific time periods in the year yields a much higher success. As a rule, seeding in the <br /> dormant season of the year is the most successful. Seeding during the growing season can yield good <br /> results, but there are many more variables during the growing season that can work against success. <br /> (TR-07 Note: Experience in the older reclamation areas has shown that seeding can occur at any <br /> time of the year and be successful. However, seeding prior to mid-May and after about August 20 tends to <br /> encounter the fewest problems with erosion or prolonged dry spells. Noxious weeds are not a serious <br /> problem on the remaining area to be mined, so the previous pre-treatment technique is not necessary.) <br /> The preferred sequence of events: Ideally, the following should be done in sequence and at the <br /> same time. <br /> I. Backfill the pit and grade the surface,but wait until the planting period to topsoil <br /> the site. <br /> 2. Topsoil the site either from a topsoil stockpile or, preferably, with freshly stripped <br /> soil from a new mining area. <br /> 3. Final grade the topsoil. <br /> 4. Plant the site. <br /> If steps 2 through 4 are done in a single, sequential operation, the success rate of the revegetation <br /> will be the highest. If that is not possible then doing steps 1 and 2 as a unit followed by steps 3 and 4 at a <br /> later time (within a few months), success will still be high. But doing steps 1 through 3 and then step 4 by <br /> itself at a later time will most likely yield, at best, only moderate success or, at worst, failure. <br /> Drill Seeding: All initial seeding will be done using the drilling method. Broadcast seeding is <br /> only allowed to interseed a previously drilled planting if its development is so poor that interseeding is <br /> needed but successful enough that re-drilling would excessively damage the existing vegetation. <br /> REQUIREMENT 22: No irrigation will occur other than natural rainfall. <br /> [Mulches: Mulch has been found to be detrimental to the development of the <br /> warm-season grasses in the revegetation. Therefore, no mulching will be done.] <br /> Seed Mixtures: There were two seed mixtures in this plan. Only one is still relevant - the <br /> former Upland Mixture. <br /> The seeding rates are shown with both a drilled rate and a broadcast rate. Select the seeding rate <br /> appropriate to the seeding method. Do not use the drilled rate for broadcasting or the broadcast rate for <br /> drill seeding. Broadcasting is to be used only for interseeding. <br /> Coal Creek Sand Resource Amendment 3 (2005)- M-1988-044 Exhibit E Page 16 <br />
