Ms. Christina Kamnika~ <br />December 1, 1999 <br />Page 2 <br />2. Final closure of the disposed CKD in C-Pit shall include a 2 foot layer of <br />compacted shale and clay covered with topsoil and planted as currently <br />provided for in Permit No. M-77-208. <br />3. Any water accumulation in C-Pit shall be monitored twice a year for thallium <br />and selenium. Since the A-Pit lake is currently the source for much of the <br />water in C-Pit (sprinkler accumulation) A-Pit will be monitored twice a year for <br />thallium and selenium to establish an "upgradient" water quality. Monitoring <br />results shall be submitted to the Division with the Annual Report. <br />If you have any questions, please feel free to call me at 303-274-4277. <br />Sincerely, <br />~ ~,~ /~s- <br />Paul Banks <br />PBlkj <br />Enclosures <br />Cc: John Lohr <br />File <br />Lyons Quarry 99004 <br />Southdown, Inc.
