Please illustrate the descriptions provided in Section 6.4.20(8) of Exhibit T, with <br />geologic and/or stratigraphic cross-sections, underground mine maps and surface maps. Please <br />identify and locate on maps, known fracture systems. Please provide a plan whereby the general <br />direction and rate of flow of ground water in the aquifers and fracture systems may be verified. <br />Please provide a plan whereby hydrologic testing and analysis of the ground water in these <br />systems may occur. <br />Response #36 <br />Adequacy Issue #36 has been addressed in Attachment H and as referenced and as <br />required by under Rule 6.4.21(8)(b), (c), (d) and (e). <br />Adequacy Issue #37 <br />In sections 6.4.20(8), (9), (12) and (19) of Exhibit T, Environmental Protection Plan, the <br />Applicant proposes to characterize ground water and establish baseline conditions by sampling <br />from only one location; the discharge from the collapsed Idaho No. 1 Adit.
