Since some map units have moderate to high clay contents (2VE, 25E, and 66E), topsoil • <br />salvage operations will occur when these soil profiles are not saturated. Localized <br />inclusions of sandstone rock outcrop and areas of high coarse fragment content rvill be <br />avoided during topsoil salvage. Steep slopes may increase topsoil losses slightly during <br />brush clearing and topsoil salvage. The mean topsoil salvage depths, presented in Table <br />9-8-1 and Exhibit 9-1, have been adjusted for all of the aforementioned limitations. <br />Topsoil Replacement <br />Salvaged topsoil will either be hauled directly to and redistributed on final regraded <br />spoil areas or stockpiled at locations BB or MN (Exhibit 12-1, Operations Plan). <br />Approximately 2.2 feet of suitable topsoil is available to be salvaged within the North <br />Wadge Deadhead Area (Table 9-8-1). The additional topsoil will be combined with the <br />existing reserves at Seneca Mine. The current, approved topsoil replacement depth for <br />Seneca II Mine, including the East Wadge Extension Area, is 1.0 to 1.1 feet (see topsoil <br />balance sections of the Second and Third Annual Topsoil and Spoil Monitoring Reports). <br />The topsoil replacement depth for Seneca Mine, after incorporating the North Wadge <br />Deadhead Area, will remain at 1.0 to 1.1 feet. • <br />J <br />9-8-6 Revised 04/06/89 <br />
