Pendleton Comment !2 "On page 2 of the report, the consultant states; Final designs and con- struction drawings of facilities to protect the waste piles from potentially damaging Ralston Creek flood flows will be prepared, if necessary, after approvals of the permit applications are obtained." Final designs and constructions drawings must be included within the permit application documents." Cotter Response See drawings prepared in conjunction with Appendix E-4. Pendleton Comment (3) "On pages 23 and 24 of the report, the applicant's consultant observes that a portion of the southern end of the existing east waste pile is unstable under wet conditions and "the removal of the waste pile material from s]opes of this grade (or steeper} is a necessity." The applicant should be required to specify exactly which portion of the existing east • waste pile this statement is intended to characterize. Further, the appli- cant should be required to include Specifications far prompt excavation and redeposition of the affected waste materials within the permit application document." Cotter Response See drawings prepared in conjunction with Appendix E-4. Pendleton Comment (4) "On page 25 of the report, the appTicant's consultant recommends ghat one or more intermediate terraces be constructed on the faces of the ~oaste piles, in order to facilitate access to the relatively steep 2;1 (horizontal to vertical) slopes for future reclamation purposes. The apparent surplus material storage volume of approximately 63,000 ~:ubic yards would allow for the provision of some terraces without loss of necessary waste accommodation. On page 27 of the report, the applicant's consultants discuss the possible consequences of erosion of the piles' toe as the result of a probable maximum flood event on Ralston Creek. The stability analysis performed supports the consultants' contention that, during such an event, a large- scale catastrophic pile failure is not expected to occur, but rather
