Those embankments will be built using <br />9 fill available on-site and they are built with the <br />10 drainage blankets to promote drainage through the <br />11 embankments. <br />12 These embankments are not dams and they <br />13 are not designed to impound water. They .are <br />14 designed to allow water to drain through ~=hem to <br />15 achieve the consolidation and dewatering Uf the <br />16 tailings that you want to achieve in this process. <br />17 There is an internal water collection <br />18 system associated with the tailings. That: will -- <br />19 that also is designed to enhance tailing, dewatering <br />20 and reduce the head. That is designed to be <br />21 effective throughout the life, but will serve its <br />22 primary function during the initial stages of <br />23 deposition when the tailings are being deposited <br />24 right on top of the liner. <br />25 That is a drainage blanket consisting of <br />AGREN, BLANDO & BILLINGS <br /> <br />
