Before beginning mining in Pit 2 the applicant must comply <br />with one of the following options: <br /> 1. Sample the overburden in Phase VI-Pit 2 by drilling <br /> at least one additional hole to determine if the SAR <br /> values for hole LM1B-4 are representative of all of Phase <br /> VI. Sample the overburden from Phase Y-Pit 1 to deter- <br />/O~i mine if the SAR values for Hole I are representative of <br />( <br />(/ <br />l „~C~ <br />~ Phase V. If the overburden SAR values for Phase VI are <br />'~~I <br />~ appreciably higher than for Phase Y then the applicant <br />~ <br />\~ must provide an alternative to using Phase YI overburden <br />~, to backfill Phase V, and provide for backfilling Phase VI <br /> overburden material into the Phase VI pit, or provide a <br /> plan for blending Phase VI material with other overburden <br /> material to provide an acceptable quality backfilling <br /> material for other areas. If the SAR values for Phase V <br /> and Phase YI overburden materials are comparable, then <br /> the applicant must provide a plan for ensuring that post- <br /> mining SAR values are comparable to premining SAR values <br /> to at least the average rooting depth (five feet) below ~ <br /> v <br /> ground level, but the applicant may use Phase VI over- 3 <br /> burden material to backfill Phase V. ~~ <br /> <br />i _p <br />~~ '~ 2~ Assume hole LM1B-4 adequately characterizes Phase VI ~? <br />\,`~j (~~ ~~~///and sample only the overburden from Phase V.
