Corey Heaps CAM - Colorado, LLC November 30, 2010 Page 19 revegetation would be conducted during the 3 rd or 4th year following permanent cessation of operations, to be consistent with the reclamation schedule in 2.05.4(2)(a). 68. Please clarify that the seeding techniques for surface roughening described in Section 2.05.4(2)(e)(iii) apply to both interim and permanent seeding. 69. Under the mulching techniques, please clarify the hydroseeding mulching techniques. Address the type and rate of tackifier or other materials to be used for mulching when hydroseeding sites. 70. For the 22 -acre of barren/sterile disturbed soils, what type of amendment or alternative surfacing is proposed? 71. For the Noxious Weed Control Plan, please include a broader statement in the second paragraph to comply with 4.15.1(5). Species to be considered include those that are on the State `A' List and those that are on the Mesa County noxious weed list. The County Weed Supervisor should be consulted for appropriate treatment methods. 72. In the third paragraph of the Noxious Weed Control Plan, please delete "If required ", at the beginning of the paragraph and replace it with, "If salt cedar plants establish on the disturbed area... ". 73. Section 2.05.4(2)(e)(vi). It seems that CAM is not proposing to seed the disturbed land/industrial portion of the permit area. If that is the case, please clarify and address a gravel surface or other measures that will be used to control wind and water erosion as required by Rule 4.15.10(3). 74. CAM is not proposing a woody plant density standard for revegetation success. Per Rule 4.15.8(7), for areas with a post - mining land use of fish and wildlife habitat, minimum stocking levels, planting arrangements, and methods for mitigation of potential adverse impacts must be determined on the basis of local and regional conditions after consultation with and approval by the Colorado Division of Wildlife (DOW). CAM must provide a basis for not reestablishing woody plants; and documentation that DOW has been consulted and that DOW approves of no shrub standard must be provided. 75. For the diversity success standard, the Division believes it would be appropriate to also include a half -shrub and a perennial grass component. 76. CAM is not proposing to sample for woody stem density in the revegetation. This is based on the as yet to be approved proposal to not include a woody plant density standard. Since shrubs are a major component of the baseline vegetation community, it is likely that shrubs will also be a major component in the reclamation and therefore, the shrub density should be collected. Please include data collection for woody stem density in the reclamation.
