I additional disturbances are contemplated; however, should the need arise to disturb <br />• additional areas, site clearing and topsoil salvage would be performed during the periods <br />indicated in Figure 17-1. <br />Facility demolition will occur first. These activities would probably occur in early <br />auimner to take advantage of favorable ground condi tiona anfl minimise in~acta to soil <br />resources. These activities will include removal of the bu3ldinga, coal conveyors and <br />equipment, tipple and railroad track. To the degree pos Bible, materials an8 equipment <br />will be salvaged for use at another facility oz as scrap. It is expected that the <br />facility demolition can be completed in four weeks. <br />Backf illing and grading will be the second activity <onducted. Di aturbance areas will be <br />backf illefl and graded Co blend into the surrounding topography, while maintaining positive <br />drainage. Moat earthmoving activities will involve backf illing and gradiag Che railroad <br />spur. Coal fines in the loadovt pile and <oal storage area will be vaefl as backf ill <br />material. HGTI anticipates that the backf illing and grading can be completed is four <br />weeks to six weeks (see Table 17-1). <br />Topsoil material redistribution and suitability determinations ITab 19) will follow <br />backfill and grading activities. It is expected that the topsoil materiel zeflistzibvti on <br />• activities can be completed in four weeks. Tillage and seedbed preparation (when <br />necessary), cover cropping and reclamation seeding will be completed during the first <br />favorable growing season after Lopsoil redistribution, weather permitting Isee Tab 20). <br />It is expected that tillage and seedbefl preparation can be completed in one to two weeks <br />and the reclamation seeding activities can be completed in one week. It is anticipated <br />that the seeding a<tivi ti ea will be scheduled for the fall season to take advantage of <br />optimal soil moisture conditions. <br />Fence construc[i on (it necessary) will occur after the seeding activities have been <br />completed. Since HGTI is uncertain if any new fences will need to be constructed as part <br />of final reclamation, fence construction is not shown on Figure 17-1. <br />Maintenance and management activities are conducted throughout [he year, weather and <br />snowpack conditions permi[tinc. The timing of these activities is dependent upon the <br />specific activity. Fence maintenance and trespass livestock removal is generally <br />conducted from mid-Spring through the Fall. Interseeding or reseeding is conducted in Che <br />next favorable planting season following recognition for the need to conduct these <br />activities. Erosion monitoring is conducted in accordance with the Stormwater Management <br />Plan lafter snowmelt and heavy rains), with any required repairs carried out from late <br />• spring through fall. The operations outlined above will be completed in winter months as <br />well when mild weather persists. Under normal conditions, the schedules, as presented, <br />are followed. <br />3 Revised 3/20/03 <br />
