<br />_ 11 _ <br />Information in Table 29 shows that topsoil ranging in depth from 6" to <br />over 50" would be lost if salvage operations were not conducted on <br />slopes ranging from 20° to 35°, Why could topsoil on slopes steeper <br />than 20° not be salvaged by utilizing bulldozers to push the soil into <br />piles at the base of the slope for subsequent removal by a truck/loader <br />or scraper operation? <br />The topsoil salvage plan and topsoil balance calculations should be <br />revised to reflect salvage of soil from the steep valley sidestopes. <br />This would apply to topsoil salvage associated with road construction <br />as well. The statement on page 2.05-14 which states that topsoil would <br />be removed "wherever practicable" should be reworded. <br />~4~• Additional detail should be provided regarding the use of diversion <br />ditches for soil stabilization. Information regarding diversion size <br />and gradient, spacing, maintenance and slope conditions on which <br />diversions would be installed should be provided. The Division feels <br />that diversions are of significant benefit on long moderately steep to <br />steep slopes if they are appropriately sized and properly maintained, <br />~~` A description of measures which will be implemented in the field to <br />L`' r. ensure appropriate salvage depths and procedures and replacement depths <br />J`~~;;;; should be included in the application, Also, a system for monitoring <br />.~ actual topsoil volumes to verify the relative accuracy of projections <br />should be proposed. <br />? <br />r", 6, Please commit to topsoil salvage and the placement of topsoil buffer <br />;;~,, zones prior to road and fill construction per Rule 4.06.2(1) and reword <br />page 2.05-14 accordingly <br />"# ,Ve tation - Rules 2.04,10, 2.05.4(2)(e) and 4.15 <br />1~.~. The application proposes that artificial seeding will not be undertaken <br />on live handled soils unless the natural seeding from live handle <br />topsoil fails. <br />° We have two requests regarding the live handle proposal. First, we <br />;, ,j- request that the first year data from the 1985 live handle field trial <br />~~',~ plots be submitted, Second, a plan for measuring the success or <br />failure of live handle stands (which would determine whether or not <br />~ ~ supplemental seeding would be required) should be included in the <br />;!`,- ~'` application (see comment No. 4 later in this section). <br />2,'~ With respect to steep slope seeding, are any areas so steep as to <br />prevent operations on the contour? If so, such areas should be <br />delineated and soil stabilization measures to be employed on such <br />slopes should be specified. <br />
