Shelton <br />Director <br />TO: Mike Zong F/~ <br />~ FROM: David Craig `( <br />~_ <br />RE: Chimney Rock Coal - Hydrologic Monitoring <br />Pursuant to your request, I have reviewed the baseline hydrologic monitoring <br />data submitted by the Chimney Rock Coal Company. A sufficient amount of <br />baseline data has been submitted. A monitoring plan may now be developed <br />which focuses specifically on the potential impacts. The following tables <br />represent my recommendation as to how this monitoring plan should be <br />carried out. Many of the chemical parameters have been deleted from the <br />baseline program because they are not considered to be potentially affected <br />by the proposed mining operations. Also, several ground water monitoring <br />sites have been deleted because they are not appropriately located to <br />detect impacts. <br />Table I.
