Mike Boulay -34- April 11, 2011 <br />68. Please clarify that the seeding techniques for surface roughening described <br />in Section 2.05.4(2)(e)(iii) apply to both interim and permanent seeding. <br />CAM: Please see revised page 2.05-32 <br />69. Under the mulching techniques, please clarify the hydroseeding mulching <br />techniques. Address the type and rate of tackifier or other materials to be <br />used for mulching when hydroseeding sites. <br />CAM: Please see revised page 2.05-32 <br />70. For the 22-acre of barren/sterile disturbed soils, what type of amendment or <br />alternative surfacing is proposed? <br />CAM: Please see section 2.05.4(1) for discussion. <br />71. For the Noxious Weed Control Plan, please include a broader statement in the <br />second paragraph to comply with 4.15.1(5). Species to be considered <br />include those that are on the State `A' List and those that are on the Mesa <br />County noxious weed list. The County Weed Supervisor should be <br />consulted for appropriate treatment methods. <br />CAM: Please see revised page 2.05-33. <br />72. In the third paragraph of the Noxious Weed Control Plan, please delete "If <br />required", at the beginning of the paragraph and replace it with, "If salt cedar <br />plants establish on the disturbed area...". <br />CAM: Please see revised page 2.05-33 <br />73. Section 2.05.4(2)(e)(vi). It seems that CAM is not proposing to seed the disturbed <br />land/industrial portion of the permit area. If that is the case, please clarify and <br />address a gravel surface or other measures that will be used to control wind <br />and water erosion as required by Rule 4.15.10(3). <br />CAM: Please see discussion in section 2.05.4(1) for a discussion regarding Rule <br />4.15.10(3). <br />74. CAM is not proposing a woody plant density standard for revegetation success. <br />Per Rule 4.15.8(7), for areas with a post-mining land use of fish and wildlife <br />habitat, minimum stocking levels, planting arrangements, and methods for <br />mitigation of potential adverse impacts must be determined on the basis of local <br />and regional conditions after consultation with and approval by the Colorado <br />Division of Wildlife (DOW). CAM must provide a basis for not reestablishing
