Western Slope Flagstaff Quarry No.2 Irrigation Pipeline Removal Reclamation Plan <br /> RECLAMATION <br /> Trench Backfilling <br /> Fill material will be returned to the pipeline trench and irrigation earthen laterals <br /> and compacted appropriately to reduce the likelihood of trench settling or <br /> erosion. Backfill shall be mechanically compacted by means of tamping or wheel <br /> rolling. The pipeline trench will be monitored and maintained to minimize settling <br /> and/or erosion control. <br /> Surface Grading <br /> Grade all areas disturbed by the pipeline and lateral removal operations after <br /> completion of backfilling and compacting. Replace and repair any surface <br /> improvements damaged or removed. Grade all areas to match the existing <br /> ground lines. <br /> The practice of re-contouring is considered to be a practice that restores proper <br /> function of the disturbed area through soil stabilization and facilitates autogenic <br /> repair of the landscape. <br /> Seeding of Disturbed Areas: <br /> Seeding of the disturbed areas will be performed within an acceptable timeframe. <br /> Typically, a late summer planting of perennials is recommended as opposed to a <br /> spring planting, as weed competition in the spring can overwhelm the seeded <br /> crop. <br /> The seed mix will be applied in order to establish permanent wind and water <br /> erosion protection, and to create a self-sustaining vegetative community. Prior to <br /> seed application, the seedbed shall be prepared via tilling the soil to a minimum <br /> depth of 4" by utilizing a disk or harrow. In all accessible areas, seeding will be <br /> accomplished using a rangeland drill. Seed shall be drilled to a depth of '/" to <br /> '/2". In areas where a rangeland drill cannot access or the soil is too rocky, seed <br /> will be hand broadcasted at twice the drill rate, and harrowed to provide an <br /> adequate degree of soil to seed contact. <br /> Seed and seed labels shall conform to all current State and Federal regulations <br /> and will be subject to the testing provisions of the Association of Official Seed <br /> Analysis. Computations for quantity of seed required are based on the percent of <br /> purity and percent of germination. Pounds of Seed x (Purity x Germination) _ <br /> Pounds of Pure Live Seed (PLS). <br /> Colorado State University Extension Range Management — Western Region <br /> Office was consulted on the appropriate reclamation seed mix for the disturbed <br /> areas.
