r~ <br /> <br />Letter to Alana Scott 3 December 23 1993 <br />Raise 2. BMRI has indicated a concern that the piezometers will <br />likely become at least partially filled with sand and slimes. The <br />Division's view is that installation of a properly graded filter <br />pack around the screened interval would eliminate intrusion of <br />tailing into the stand-pipe. Both the Division and WWL have <br />specific ideas regarding design and installation of effective <br />tailings piezometers, and would be willing to work with BMRI on <br />those aspects of the project if desired. <br />As discussed previously, the Division will refrain from providing <br />a review of the remaining aspects of TR-016 until data from on- <br />going tests is provided. The Division will also be incorporating <br />input from WWL into the review of TR-016, as suggested by BMRI. <br />If you have any questions, please contact myself or Larry Oehler. <br />Sincerely, <br />Allen C. Sorenson <br />Reclamation Specialist <br />cc:t Larry Oehler, DMG <br />Clint Strachen & Doug Gibbs, WWL (via FAX) <br />M:\MIN\ACS\BMRI <br />
