' Preliminary Adequacy Review <br />-~sar Coal Co., Inc. - Bear Mine <br />Page Eight <br />,~J5.9 (2)(e) Revegetation <br />2.05.4(2)(e)(i) Schedule of Revegetation <br />' The applicant should specify whether seeding of the permanent mix will be done in <br />sr, ring or fall. Fall seeding is generally recommended. The year(s) and season(s) in <br />which shrub plantings are proposed should be specified. SAGE 71 <br />' 2.05.4(2) (e) (ii) Seedmix <br />-oth the stabilization Seedmix and the permanent Seedmix should be expressed on a <br />' PIS seeds per square foot, as well as pounds per acre, basis for individual species. <br />The proposed seeding rate appears too light - 25 to 30 pure live seeds per square <br />foot is commonly recommended for drill seedings, with twice that amount advisable <br />for broadcast seeding. The applicant should revise the Seedmix in this light. The <br />' potential for diversity in the post-mining vegetation is rather limited with the seed- <br />r„ix proposed. Some additional native grasses and shrubs should be included in the <br />rtix. Slender wheatgrass, streambank wheatgrass, great basin wild rye, service <br />' Lorry, antelope bitterbrush and chokecherry are species that might be included in <br />the Seedmix. TABLE 2,05,~:(2)(a)-2 & 2,05.!!(2)(E)(II) PAGE 72 <br />"' 05.9(2)(e)(iii) Planting Methods <br />'Fore detail should be provided regarding seeding and planting methods. The applicant <br />~~tes only that "hand seeding will be used." The applicant should specify how <br />seedbed will be prepared, how seeding on the steep slopes in the vicinity of <br />the West portals will be carried out, and how seed coverage will be accomplished. <br />' i~ri11 seeding is generally more effective on level areas than broadcast seeding, and <br />should be considered by the applicant. <br />PAGE 72 <br />I't is stated in the application that trees will be planted randomly over the area <br />after the seeded vegetation has been established. Cottonwood, Willow and Rawthorne <br />...~~ proposed. The number of seedlings to be planted and the method of planting - <br />:,~hether bare roof or tubeling - should be specified. Rather than distributed randomly <br />aver the area, the Willow and Cottonwood should be planted in the riparian area <br />adjacent to the river bank. Native species such as rose, serviceberry, and currant <br />=.hould be considered for other areas. Certain woody species should be included in <br />the Seedmix (see comment under Section 2.05.4(2)(e)(ii)). PAGE <br />72 <br />__05.4(2) (e) (iv) Mulching Techniques <br />' 7'he applicant should explain how an even distribution of straw mulch will be <br />~:~chieved without using a mechanized straw blower. PAGE 72 <br />05.9(2)(e)(vi) Revegetation Success <br />~. Due to the continued use of the existing disturbed area at Bear Mine, the <br />irea does not qualify as a previously disturbed area. The applicant will be required <br />t:o address the success criteria of Rule 4.15.8. <br />~~ PAGE 72-7~c <br />1 <br />
