Rule 2: Permits <br />Timing of Seeding <br />Revegetation will occur after final grading and redistribution of subsoil and topsoil <br />activities have taken place. Seeding will be coordinated with the other reclamation <br />activities to occur as soon after seedbed preparation as possible. Fall seeding <br />(September to November) is recommended based on local soil moisture conditions, <br />germination requirements of selected species, and adaptation of seed to soil <br />temperature. Spring seeding (March to May) will be practiced if areas are ready for <br />revegetation and access is possible. Seeding from November to March may be <br />practiced, soil conditions permitting. Mixed seedings, one seeding to plant cool <br />season plants in early fall and one seeding to plant warm season plants in spring, will <br />be timed to avoid competition between species and avoid seed distribution problems. <br />Interim revegetation of sites, like on topsoil storage piles to be stabilized prior to <br />permanent revegetation, will be conducted as soon after construction as possible. <br />Mulching <br />Mulching aids in erosion control, soil moisture retention, and provides supplemental <br />organic material to the soil. Mulch will be evenly distributed over the seeded area at <br />rates dependent on seeding method and slope. Certified weed -free straw or grass hay <br />mulch will be applied at rates of 1 to 2.0 tons /acre on drill seeded areas and at least 1.5 <br />tons /acre on steeper slopes of greater than ten percent and 2.0 tons /acre on areas <br />determined to be deficient in organic material as indicated by soil analysis. Mulch <br />will be anchored into the seed bed using a mulch crimper or disk, tackifier, or netting. <br />If used, hydromulch will be applied at a rate of at least 250 pounds /acre. A tackifier <br />will be used on hydromulched areas that are mulched in the fall and on areas which <br />require prompt stabilization. A temporary cover crop of a suitable annual grain, like <br />annual rye, may be seeded to control erosion until a permanent cover can be <br />established. <br />Vegetation Monitoring <br />LCC will conduct periodic monitoring of vegetation as prescribed by the CDMG. The <br />objective of the monitoring program is to assess the success of revegetation in <br />disturbed areas. <br />Revegetated areas will be evaluated for cover and density during the first two seasons <br />following seeding to determine initial revegetation success. Initial seeding follows <br />interim seeding once permanent reclamation is deemed appropriate. In years 3, 5, and 7 <br />following seeding, revegetated areas will be visually evaluated for cover, density, and <br />species diversity. Areas with poor germination and/or growth will be documented and <br />evaluated to determine probable causes. The operator will conduct such evaluations as <br />necessary, revise reclamation techniques to address any identified problems and make a <br />second attempt to revegetate problem areas. Findings and results will be documented in <br />the Annual Reclamation Report detailing findings and the corrective action employed. <br />0 It is anticipated that revegetation methods and seed mixtures proposed in this <br />reclamation plan may be modified, after Division approval, reflecting plant material <br />TR -16 2.05 -70 (Revised 7/15/07) <br />
