Mike Boulay <br />-29- October 16, 2012 <br />72. After the cheatgrass is treated with roundup, the Division suggests that the <br />topsoil pile be reseeded with the temporary seed mix to hinder reinvasion of <br />cheatgrass. <br />MCM: Comment noted. <br />73. Please include a plan for continued monitoring and managing of other pests and <br />weeds found on the site but not mentioned in 2.05.4(e)(v) but listed in Appendix <br />U, Noxious Weeds, page 6 and Appendix V, 7.1 Noxious Weeds, Table 16, page <br />44. These include species that are on the Garfield County and Colorado <br />Department of Agriculture weed lists. <br />MCM: Since MCM is no longer proposing expansion to surface facilities, Appendix U is <br />no longer included for consideration. Please see discussion of noxious weeds in <br />on page 2.05 -44. <br />74. The Division agrees with and approves the recommendation to use the <br />Greasewood Reference Area as the ultimate revegetation success standard for <br />all of the Greasewood areas to be disturbed. <br />MCM: Comment noted. <br />75. Woody plant density — The previous reference data (Vegetation Inventory <br />4.5.10.1 -3 1980) documents that shrub density for each community is: <br />greasewood — 3386/ac, shadscale — 1790/ac and juniper — 1797/ac. These <br />densities are not reflected proportionally in the targeted reclamation standard <br />densities: greasewood — 500 /ac, shadscale — 500 /ac and juniper 1,500 /ac. <br />However, the new predisturbance data suggests that the proposed proportions <br />are correct (Append U, Table 2.04.10 -5, -8). However, it is not clear how the <br />proposed density standards were established. Additionally, all density standards <br />need to be based on consultation with the Colorado DOW as per rule 4.15.8(7). <br />Please explain how the density standard was determined including <br />documentation from the DOW. <br />MCM: Appendix U is no longer included for consideration. Density standards will revert <br />back to approved density standard as shown in Section 2.05.4. <br />76. Diversity — A minimum of forb species is not proposed . Please include forb <br />species in the diversity standard. <br />MCM: Appendix U is no longer included for consideration. Diversity standards will <br />revert back to approved standard as shown in Section 2.05.4. <br />
