• The proposed Packrat portal area disturbance is on land that has been completely disturbed in the past, <br />as seen on Map C-lA. The former waste embankment was previously reclaimed by regrading, placing <br />imported topsoil, and creating depressions on the land surface to provide pockets where seed could <br />more readily germinate. The majority of the reclaimed waste embankment will not be re-disturbed. <br />Only the upper portion of the waste embankment will be disturbed to allow for a portal bench with <br />some minor facilities. <br />Table D-1 below shows a breakdown of proposed surface disturbance between previously impacted <br />areas and areas that were not impacted extensively by historic operations. <br />As mentioned in Section 1, some of these surface facilities, such as the reopening of mine access roads, <br />pads, and portals, were approved under previously submitted prospect applications. This mine permit <br />application encompasses these disturbances and is intended to supersede and replace those exploration <br />permits. <br />• <br />• <br />Whirlwind Mine 07 (rev.
