The ponds are also <br />checked weekly during NPDES water quality checks. All ponds were <br />found to be structurally sound and functioning properly with <br />adequate storage capacity to satisfy requirements set forth in the <br />Edna Mine permit. All ponds will be surveyed during the 3rd <br />quarter of the year and sediment capacity data will be further <br />updated. <br />Should you have any questions regarding these reports, please <br />contact me at the Edna Mine site. <br />incerely, <br />-~ <br />David Beverlin <br />Resident Engineer <br />cc: Mine File <br />
