It contains the detailed analysis and design <br />plan for placing a slurry wall around the first reservoir area. <br />we are submitting this copy for your review per our commitment on <br />page 1 - last paragraph of the amendment submitted in 2004. PS&G <br />hopes to get the go ahead from the Division to start construction <br />per the GUIDE TO SPECIFICATION PREPARATION FOR SLURRY WALLS AND CLAY LINERS <br />AS A COMPONENT OF A COLORADO MINED LAND RECLAMATION BOARD PERMIT, September <br />2000, under PERMITTING OPTIONS bullet 3. This would allow PS&G to <br />install the wall under the existing bond and get the amendment <br />approval issued. Then when the wall is in and the QAQC is <br />completed a new bond would be calculated to include the current <br />reclamation costs plus the 208 reduced bond. <br />Thank you for your help and if you have any questions call <br />me at 303-423-7297. <br />Respectfully Submitted, <br />Environment, Inc. <br />~~e..'~ <br />Stevan L.
