<br /> <br />RECLAMATION CONDITIONS <br />Several options are available for creation of a stable (Factors of <br />Safety greater than 1.3) reclaimed scope. The following option as <br />first described in the stipulation Pesponse Document, has been <br />selected. <br />o Option 2 - Partial backfill against the lower portion <br />of the highwall to contain rock fall and minor regrading <br />of upslope colluvial material. <br />The existing bench fill area below the portal bench will be regraded <br />to a slope of 25 degrees or less with utilization of a cut and fill <br />balance approach. <br />(Excerpted from Stipulation Response Document, page 12.) <br />Option 2 <br />Option 2 is characterized by partial filling of the-bench <br />area at an angle of approximately 15 degrees. This provides <br />backfill at a point approximately half way up on the excavated <br />highwall. Raveling of the material above the fill area is <br />expected, with minor release of large rocks on to the fill area. <br />This condition is identical to the phenomenon on natural slopes <br />throughout the area. The rock fall is expected to be contained <br />on the 15 degree slope and build up to a level approaching the <br />reclaimed slope of Option 1. When the build up is complete, the <br />final condition will be stable and no further rock fall is <br />expected. The fill required for this option was estimated to be <br />approximately 17,000 cubic yards. <br />
