• Site clearing is performed immediately prior to soil removal in a given area. Clearing <br />includes removal of woody or other materials which could interfere with soil removal, or <br />potentially contaminate soil. Site clearing and soil salvage operations are typically <br />conducted from May to November. These activities may be conducted in other months if <br />weather conditions permit. <br />gac kfilling and grading activities are performed throughout the year. <br />Soil redistribution and associated graded spoil suitability determinations follow the same <br />timetable as salvage operations. If ground conditions permit, soil redistribution may be <br />conducted in months other than the primary months indicated in the reclamation timetable <br />(Figure 13-1). Tillage and seedbed preparation (when necessary), cover cropping, end <br />seeding of resoiled areas is conducted in the next favorable planting season after soil <br />redistribution, weather permitting. Therefore, the schedule for these activities may <br />parallel the soil redistribution schedule in many cases. Tree and shrub planting is <br />performed in [he fell es dormant plantings, but may be planted in spring on occasion. <br />Tree and shrub planting areas are prepared during spring, summer, and fell. <br />Fence construction is generally performed from April to November. Construction is <br />interrupted only 6y inclement weather or snowpack. <br />Maintenance and management activities ere conducted throughout the year, weather and <br />snowpack conditions permitting. The timing of these activities is dependent upon the <br />specific activity. Fence maintenance and removal of any trespass livestock ere generally <br />conducted from mid-spring through fall. Interseeding and any necessary reseeding is <br />conducted in the next favorable planting season following the decision to interseed or <br />reseed. Erosion monitoring is conducted after snowmelt and heavy rains, with any required <br />repairs carried out from late spring through fall. Occasionally, [he operations outlined <br />above will be completed during winter months when mild weather persists. Under normal <br />conditions, the schedules are as presented. <br />Protected Reclamation Schedules. The projected backfilling and grading schedule for the <br />remaining Seneca It life-of-mine is presented on Exhibit 13.2. <br />. The annual projection of areas graded as presented on Exhibit 13-2 are based upon certain <br />basic considerations. First, the backfilling and grading schedule is based upon the <br />operation plan, coal excavation cycle times, and pit configuration. Cycle times are <br />13-63 Revised 12/01/93 <br />
