Newmont‐Cripple Creek & Victor Gold Mine <br />Technical Specification No. 02200.DOCX <br />Squaw Gulch VLF <br />Project No.475.0106.006 <br />June 15, 2016 <br /> <br /> <br /> <br />Page 13 <br />2. CONTRACTOR shall condition Leak Detection Fill to allow a surface that does not <br />cause rutting or other deleterious effects. <br />F. Low Volume Solution Collection Fill <br />1. Low Volume Solution Collection Fill shall be placed over the geomembrane in the <br />locations shown on the DRAWINGS. <br />2. CONTRACTOR shall condition Low Volume Solution Collection Fill to allow a surface <br />that does not cause rutting or other deleterious effects. <br />3. CONTRACTOR shall place Low Volume Solution Collection Fill around the Low <br />Volume Solution Collection Vertical Riser Pipes in maximum 12‐inch loose lifts and <br />compact using a hand operated vibratory plate compactor to the satisfaction of the <br />MANAGER and CERTIFYING ENGINEER. Low Volume Solution Collection Fill shall be <br />worked under the Low Volume Solution Collection Rise pipe haunches by hand to <br />provide uniform support of the pipe. <br />4. Prior to placing the Low Volume Solution Collection Fill, CONTRACTOR shall verify <br />by visual inspection that the underlying geosynthetics are free of holes, tears, <br />wrinkles, or foreign objects. MANAGER and CERTIFYING ENGINEER will inspect the <br />geosynthetic for wrinkles prior to placement of Low Volume Solution Collection Fill. <br />As instructed by MANAGER, CONTRACTOR shall "work out" wrinkles to the <br />satisfaction of MANAGER and CERTIFYING ENGINEER prior to placement of the Low <br />Volume Solution Collection Fill. In all cases, wrinkles shall not be of a size that they <br />could fold back on themselves. Wrinkles greater than one foot shall be removed <br />and repaired by the INSTALLER. <br />5. CONTRACTOR shall place Low Volume Solution Collection Fill in a single 36‐inch <br />loose lift. The tracked equipment shall operate only over previously placed Low <br />Volume Solution Collection Fill. CONTRACTOR shall not operate equipment directly <br />on geosynthetics. Only a dozer with a ground pressure not exceeding 14.7 psi can <br />be used to place Low Volume Solution Collection Fill. Equipment used for <br />placement will not be allowed to pivot on one track (i.e., no abrupt or sharp turns). <br />There shall be no downhill placement on slopes steeper than 4H:1V. Material can <br />be placed along contours if buttressed from below. <br />6. Rubber tired construction equipment shall not be allowed to travel over the <br />geomembrane or on top of Solution Collection piping unless a thickness of at least <br />45 inches of Low Volume Solution Collection Fill has been placed over the <br />geomembrane and on top of Solution Collection piping. The CONTRACTOR will be <br />required to demonstrate to the MANAGER, DESIGN ENGINEER and CERTIFYING <br />ENGINEER that the equipment and procedures used are not detrimental to the <br />geomembrane and piping, at no cost to CC&V. Off road haul truck traffic shall <br />require a minimum of 60 inches for Cat 773 (or equivalent) of Low Volume Solution <br />Collection Fill placed over the geomembrane and solution collection piping, and a
