Page 4of10 <br />Many typographical errors have crept into the text. These include: <br />i. Page 2.05 -7, "...fan and airshaft a small graveled parking area...." — missing <br />a full stop and capital A <br />ii. Page 2.05 -9, "Cut slopes in rock are excavated at a 0.25H:IV" should be <br />"0.25H: IV" <br />ill. Page 2.05 -9, "shot Crete" should be "shotcrete" <br />iv. Page 2.05 -10, "...NE- 17 -12, was drilled south the mine facilities" should be <br />"... south of the mine facilities" <br />v. Page 2.05 -10, "...transported back to the New Elk for disposal." The New Elk <br />what? <br />vi. Page 2.05 -17, "One 0.2 -mile long light use road provides access to slurry wells <br />82 and 83 at the west mine" — "... S2 and 53... "? <br />vii. Page 2.05 -19, "Ditch 28 will direct a combination of disturbed, and <br />undisturbed..." — unnecessary comma <br />viii. Page 2.05 -40, "Both the RDA ad the Development Waste Pile... " — should be <br />"... and the Development Waste Pile" <br />ix. Page 2.05 -41, "AASHTO T99 -74" in the old text was changed to "AASHTO <br />T99 -75" in the new text — it's not clear if this is a typo or the intentional <br />correction of an error <br />x. Page 2.05 -41, " Compaction tests will betaken frequently and location of not <br />less than one perm every other layer" — should be "... per every other layer" <br />xi. Page 2.05 -41, "...proper construction and maintenance are occurring in <br />accordance with the approve plan." — should be "...proper construction and <br />maintenance are occurring in accordance with the approved plan." <br />xii. Page 2.05 -42, "... a fabric which is inert it biological degradation" — should be <br />"... a fabric which is inert to biological degradation" <br />xiii. Page 2.05 -42, "... and had the following characteristics" — should be "... and <br />has the following characteristics" <br />xiv. Page 2.05 -42, "As the refuse disposal area is expanded, clearing and topsoil <br />removal will proceed refuse disposal... " — should be "... will precede refuse <br />disposal... " <br />xv. Page 2.05 -44, a passage was omitted; it's not clear whether this was deliberate <br />or an error. In the old permit text, "... excessive positive water pressures are not <br />likely to develop" was followed by "within the pile (Wardwell, 1982). Because <br />of this, the water table was initially assumed to be no higher than the interface <br />between the pile and the foundation." <br />xvi. Page 2.05 -45. The formatting of the stability results has been scrambled <br />making the information difficult to read. <br />xvii. Page 2.05 -44, a passage was omitted; it's not clear whether this was deliberate <br />or an error. In the old permit text, "The actual strength of the static and pseudo <br />static safety factors for the low phreatic surface was 1.87 and 1.59, <br />respectively" was followed by "The static and pseudostatic high phreatic <br />surface were 1.61 and 1.44, respectively." <br />f Regarding table 19: <br />i. Table 19 is badly formatted which makes it difficult to read and interpret <br />ii. The facility lists are partially, but not uniformly, alphabetized <br />in The pre -law fan shaft has been omitted from the list for Map 12 <br />iv. A new category, "Permanent ", has been added to the list for Map 12 — when <br />were the West Mine access/haul road and West containment 42 approved as <br />
