If seedling [oss on reclaimed areas becomes a significant concern, EFCI will evaluate almrnative <br />control measures, review these measures with the CDMG, and obtain approval prior to <br />implementation. <br />Mulching and Soil Stabilization. As previously noted both in this section and in the discussion of <br />topsoil handling, EFC! does not clear and grub future disturbance aeeas prior to topsoil stripping. <br />Consequently all vegetative materials are recovered during topsoil stripping activities and incorporated <br />with soil materials. These incorporated vegetative materials serve as a natural mulch and provide <br />significant soil holding capability co prevenr loss or erosion of topsoil resources. In areas where a <br />significant potential for erosion may exisr, EFCI will supplement natural vegetative mulch with a <br />surface straw mulch applied at rate of two (2) [ons pet acre or will utilize hydrosceding as previously <br />described. Following mulch application, the mulch wilt be Gimped to prevent wind loss utilizing <br />either a conventional disk or similar farming implement. Supplemental mulching will be utilized for all <br />retopsoiled areas not containing natural vegetative mulch and aU slopes greater than 4H:1 V. <br />Irrigation. EFCI does nor plan to irrigate any reclaimed areas. An irrigation system would be cosdy, <br />both to establish and maintain and irrigation would offer little benefit in promoting effective long- <br />term vegetative establishment. EFCI's revegetation practices, including scheduling of seeding in late <br />fall, are designed ro take advantage of naturally elevated soli moisture levels in the spring when <br />additional soil moisture can pzomoxe effective gemrinadon and establishment of revegetadon species. <br />Pest and disease Control. EFCI will cazefully monitor reclamation seed m-xmces co prevent <br />inaoduction of any noxious weed species. If noxious weeds do become established in reclaimed <br />stands as a result of nanual invasion or other mechanisms, EFCI will consult with the Colorado State <br />Universiry-Cooperative Extension Service to identify appropriate control measures. Prior to <br />implementation of any such control measures, they will be reviewed with the CDMG and apprapriate <br />approvals obtained. <br /> <br /> <br />MR-4$ 2.05.4-24 Revised March 2003 <br />
