Post-mining final <br />graded slopes need not be uniform but shall approximate the general nature of <br />the pre-mining topography identified in 2.10.3(1)(j). The requirements of <br />4.14.2 may be modified by the Division FOR STEEP SLOPE MINING PURSUANT TO <br />4.27, FOR UNDERGROUND OPERATIONS PURSUANT TO 4.14.1(2)(e) AND (f), AND FOR <br />RE-MINING OPERATIONS PURSUANT TO 4.14.1(2)(8). where the surface coal mined <br />lands that have not been restored to the standards of these Rules and <br />sufficient spoil is not available to other;pis? comply wiCh this 4.14.

In all cases the highwall ;Hall be eliminated., UNLESS <br />RETENTION OF A HiGHWALL REMNANT IS SPECIFICALLY APPROVED BY THE DI'7ISION <br />PURSUANT TO 4.14.1(2)(f) or (g). <br />28e.
