If seedling loss on reclaimed areas becomes a significant concern, EFCI will evaluate alternative <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, EFCI does not clear and grub future disturbance areas prior to topsoil stripping. <br />Consequentl}' 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 capabilit}' to preven[ loss or erosion of topsoil resources. In areas where a <br />significant potential for erosion may exis[, EFCI will supplement natural vegetative mulch with a <br />surface straw mulch applied at rate of two (2) tons per acre or will utilize hydroseeding as previousl}' <br />described. Following mulch application, the mulch will be crimped to prevent wind loss utilizing <br />tither a convemional disk or similar farming implement. Supplemental mulching will be utilized for all <br />retopsoiled areas not containing natural vegetative mulch and all slopes greater than 4H:1 V. <br />Irrigation. EFCI does not plan to irrigate any reclaimed areas. An irrigation s}'stem would be costl}', <br />both to establish and maintain and irrigation would offer li[de benefit in promoting effective long- <br />term vegetative establishment. EFCI's revegetation practices, including scheduling of seeding in late <br />fall, are designed to take advantage of naturally elevated soil moisture levels in the spring when <br />additional soil moisture can promote effective germination and establishment of revegetation species. <br />Pest and disease Control. EFCI will carefully monitor reclamation seed mixtures to prevent <br />introduction of any noxious weed species. If noxious weeds do become established in reclaimed <br />stands as a result of natural invasion or other mechanisms, EFCI will consult with the Colorado State <br />University-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 appropriate <br />approvals obtained. <br />MR-48 2.05.4-24 Revised March 2003 <br />
