In accordance ~~ ~ <br />with Rule 4.05.13, the effluent from the treatment facilities will <br />be monitored until bond is released. Page 4a of Eahibit 15 has been <br />revised to reflect the above considerations. <br />Probable Hydrologic Consequences and Cumulative Hydrologic Impact Study - <br />Rules 2.05.6C3) and 2.07.6C2)(c) <br />The Probable Hydrologic Consequences section of the permit <br />application is divided into two main subsections: Ground Water Effects <br />and Surface Water Effects. The following comments and questions are <br />addressed under these headings. <br />A. Ground Water Effects <br />1. Dewatering <br />It is stated on pages 2.06-165 and 166 that existing data and field <br />observations of the existing pits at Mine No. 3 substantiate that surface <br />mining has not in the past, and is not expected to in the future, dewater <br />the overburden aquifer under the proposed mining plan. Therefore, no <br />drawdown of water levels in the overburden aquifer is predicted from the <br />surface operations. However, it is stated on page 2.05-168 that the <br />increased rate of recharge of the reclaimed spoils material will enable <br />rapid recovery of the original storage volume of the undisturbed <br />overburden aquifer tram the temporary dewatering due to mining. These <br />conflicting statements should be revised to clarify this situation with <br />-14- <br />
