Before beginning mining of Pit 2 the applicant must provide la~plan to ensure that postmining SAR values are at least compar- able to premining SAR values to a depth of at least the average rooting depth (five feet) below ground level. Furthermore, the applicant must justify why using better quality backfill material to at least the average rooting depth (five feet) below ground level is either not necessary or not desirable. If the applicant cannot justify why the use of better quality backfill material is neither necessary or desirable, than the applicant must provide an acceptable plan for using more desirable material. 5/!
