<br />V and Phase Vt overburden SAR values then the applicant <br />must provide a plan for insuring that postmining SAR <br />values will be equivalent to premining SAR values to at <br />least the average rooting depth (five feet) below ground <br />level, but the applicant will be allowed to use Phase VI <br />overburden material to backfill Phase V. <br />3. The applicant must show that using high SAR over- <br />burden with only 18 to 24 inches of topsoil covering will <br />allow successful reclamation of the mined area. The app- <br />licant must provide a quantified analysis of the probable <br />impacts to the hydrologic system of using Phase VI mater- <br />ial to backfill Phase V. If no impacts to reclamation <br />success or the hydrologic system will result, Phase VI <br />material may be used to backfill Phase Y. <br />A similar problem with overburden quality exists for Pit 2. <br />As stated, it is doubtful that hole LM2C-5 adequately character- <br />izes all of the overburden to the north of its location. It is <br />entirely possible that overburden SAR values, especially to the <br />east of the fault line shown on Exhibit C-56 of Appendix C as <br />east of hole LM2C-5, are higher than the SAR values noted for <br />hole LM2C-5 in Table 10 of Appendix C. It should be noted that <br />the overburden SAR values to the north of hole LM2C-5 are probab- <br />ly much better than those for hole LM1B-4. Therefore the follow- <br />ing stipulation is proposed. <br />Before beginning mining in Pit 2 the applicant must comply <br />with one of the following options. <br />1. The applicant must analyze at least two more overburden <br />samples in the Pit 2 area: one sample in Phase VII, east of <br />the fault line; and one sample from the center of proposed <br />Pit 2 near the division between Phase VIII and Phase IX. If <br />the samples show unacceptable SAR values then the applicant <br />-51- <br />
