not being used for facility or monitoring-related activities (i.e., items such as, but not limited to ramps, deadhead routes, light use roads, haul roads, ponds, drainages, diversions, boneyards, office, or shop areas). If final grade is achieved during fall or winter months, soil will be redistributed the following summer or fall to accommodate fall seeding. When final grade is accomplished during spring or summer months, soil w)II be redistributed by fall to accommodate fall seeding. The most significant disturbance is advance topsoil removal, which must be completed by November 1 of each year in order to allow the overburden removal operation to continue during the- winter and wet spring months. The efficient removal of topsoil at Yoast is considered to be virtually impossible during the six-month period from November 7 to May 1 of any given year. Consequently, ai the end of any given year, approximately one-third of the coal acreage to be mined during the next year will have been disturbed by topsoil removal activities. The total annual disturbed acreage figures in the table include the coal areas mined and the advance topsoil removed areas, as well as the other disturbances including spoil areas, existing and proposed haul roads, power lines, storage yards, and facilities. In order to avoid the confusion created by too many overlapping yearly lines, only the graded areas for each-year are shown on Exhibit 79-1A, Backfilling and Grading Plan. The facilities including utility lines, haul Toads, drainage and sediment control structures are illustrated on various maps including Exhibit 12-1 and Exhibit 19.1A and are described in Tab 13. The areas of land that will be disturbed through the five-year permit term and the Life- of-Mine are shown on Exhibit 12-1. The backfilling.and grading schedules are shown on Exhibit 19-1A.
