6.3 Dryland Pasture Seeding Procedures <br />Seeding will be done with a drill seeder that can drill the seeds into the ground to a depth that the <br />species of grass requires. Alternatively, a broadcast seeder may be used; if this is the case, seeds <br />will be broadcasted at double the drill seed rate. A large tractor mounted broadcaster having the <br />capacity of holding several bushels of grass seed will be used and the tractor will traverse the field <br />such that overlapping of the seed will occur. Forage kochia will always be broadcast seeded over <br />dryland pasture areas as part of Seed Mix #8 during fall dormant seeding. After the seed is <br />broadcasted, a spring tooth harrow will be drug over the field to bury the seed approximately 1/4 <br />inch. Since not all of the seed will be covered, the seed rate will be increased 100% over the <br />drilled seed rate. If the harrow is not utilized, such as in a topsoil stockpile situation, then the <br />broadcast rate will be double the drilled rate. <br />6.4 Revegetation Success Criteria and Statistical Procedures - Dryland Pasture <br />Revegetation will be deemed adequate if vegetation cover and herbaceous production at the <br />reclaimed site is at least 90% of the vegetative cover and herbaceous production at the reference <br />area, in conformance with CDRMS Regulations 4.15.8. One of the three statistical comparison <br />methods in CDRMS Regulations 4.15.11(2) subsections (a), (b), or (c) will be used, according to <br />the procedures list in this Sub - section 6.4. <br />The production standard for the dryland pasture type for the New Horizon 2 (NH2) area will be <br />based on a dryland reference area located at the Nucla Airport. This area was originally <br />established in the summer of 2000 and augmented in 2005. The augmentation allows the <br />reference area to be divided into two sections: one for rangeland and the other for dryland <br />pasture. This Airport Dryland Reference (ADPR) area is shown in a map in Attachment <br />2.05.4(2)(e) - 4. The map shows the original sagebrush reference area, as well as the former <br />rangeland reference area of 1999, which is no longer used. It also shows the reference area of <br />2000, which is no longer used. Adjacent to this area, and east of it, is the current reference area, <br />which was established in 2005. Although this area can also be used as a reference area for <br />rangeland, there is no restored rangeland that is planned in the mine reclamation for the New <br />Horizon #2 Mine, as of October, 2009. <br />PR -06 June 2010 2.05.4(2)(e) - 55 <br />
