seedlings. If seedling loss on reclaimed areas becomes a significant <br />concern, EFCI will evaluate alternative control measures, review these <br />measures with the CMLRD, and obtain approval prior to implementation. <br />Mulchino and Soil Stabilization. As previously noted both in this section <br />and in the discussion of topsoil handling, EFCI does not clear and grub <br />future disturbance areas prior to topsoil stripping. Consequently all <br />vegetative materials are recovered during topsoil stripping activities <br />and incorporated with soil materials. These incorporated vegetative <br />materials serve as a natural mulch and provide significant soil holding <br />capability to prevent loss or erosion of topsoil resources. In areas <br />where a significant potential for erosion may exist, EFCI will supplement <br />natural vegetative mulch with a surface straw mulch applied at a rate of <br />two (2) tons per acre or will utilize hydroseeding as previously <br />described. Following mulch application, the mulch will be crimped to <br />prevent wind loss utilizing either a conventional disk or similar farming <br />• implement. Supplemental mulching will be utilized for all retopsoiled <br />areas not containing natural vegetative mulch and all slopes greater than <br />4H:1V. <br />Irrioation. EFCI does not plan to irrigate any reclaimed areas. An <br />irrigation system would be costly both to establish and maintain and <br />irrigation would offer little benefit in promoting effective long-term <br />vegetative establishment. EFCI's revegetation practices, including <br />scheduling of seeding in late fall, are designed to take advantage of <br />naturally elevated soil moisture levels in the spring when additional soil <br />moisture can promote effective germination and establishment of <br />revegetation species. <br />Pest and Disease Control. EFCI will carefully monitor reclamation seed <br />mixtures to prevent introduction of any noxious weed species. If noxious <br />weeds do become established in reclaimed stands as a result of natural <br />invasion or other mechanisms, EFCI will consult with the Colorado State <br />University-Cooperative Extension Service to identify appropriate control <br />measures. Prior to implementation of any such control measures, they will <br />be reviewed with the CMLRD and appropriate approvals obtained. <br />2.05.4-24R Revised -November, 1990 <br />
