Newmont-Cripple Creek&Victor Gold Mine <br /> Technical Specification No.02200 REV D <br /> Squaw Gulch VLF . <br /> Project No.475.0106.006 <br /> March 13,2020 <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 require <br /> a minimum of 60 inches for Cat 773(or equivalent)of Low Volume Solution Collection <br /> Fill placed over the geomembrane and solution collection piping, and a minimum of <br /> 120 inches for CAT 777 (or equivalent) of Low Volume Solution Collection Fill placed <br /> over the geomembrane and solution collection piping. <br /> 7. When placing Low Volume Solution Collection Fill the maximum acceptable drop <br /> height is 3 feet. <br /> 8. CONTRACTOR shall operate equipment in a manner that is protective of underlying <br /> geosynthetics. If MANAGER or CERTIFYING ENGINEER suspects the occurrence of <br /> any damage to the underlying geosynthetics, MANAGER will instruct CONTRACTOR <br /> to remove Low Volume Solution Collection Fill to expose the geosynthetics. <br /> CONTRACTOR shall uncover, repair any observed damage of the underlying <br /> geosynthetics, in accordance with the repair requirements of Sections 02776.0 and <br /> 02777.0 of these SPECIFICATIONS, and recover, at no cost to CC&V. <br /> 9. CONTRACTOR shall place Low Volume Solution Collection Fill at a rate such that no <br /> single area of 350,000 square feet of geomembrane liner is exposed to ultraviolet <br /> light for more than 180 days. <br /> 10. CONTRACTOR shall provide close continuous monitoring at the point of placement <br /> during the placement of the Low Volume Solution Collection Fill over geosynthetics. <br /> 11. CONTRACTOR shall verify the final thickness of Low Volume Solution Collection Fill <br /> to determine compliance with this SPECIFICATION. CONTRACTOR shall record <br /> verification location, elevation, and thickness. CQA Monitor shall witness all <br /> verification measurements. CONTRACTOR will submit a method of verifying Low <br /> Volume Solution Collection Fill depth to MANAGER for approval. Grade markers shall <br /> be placed on a 50-by-50-foot grid with additional points required for breaks in grade. <br /> CONTRACTOR shall remove all grade markers under supervision of CQA Monitor <br /> after verification measurements have been approved by MANAGER and CERTIFYING <br /> ENGINEER and will backfill holes with Low Volume Solution Collection Fill.Areas with <br /> deficient thickness shall be reworked by CONTRACTOR, until acceptable <br /> measurements are obtained. If MANAGER or CERTIFYING ENGINEER suspects the <br /> occurrence of any damage to the underlying geosynthetics, MANAGER will instruct <br /> CONTRACTOR to remove Low Volume Solution Collection Fill to expose the <br /> geosynthetics. CONTRACTOR shall uncover, repair any observed damage of the <br /> underlying geosynthetics, in accordance with the repair requirements of Sections <br /> 02776.0 and 02777.0 of these SPECIFICATIONS and recover, at no cost to CC&V. <br /> 12. CONTRACTOR will provide adequate illumination as approved by MANAGER, if Low <br /> Volume Solution Collection Fill placement is carried out at night. A minimum of 2- <br /> foot candles measured at the synthetic liner, shall be used when Low Volume <br /> Solution Collection Fill placement is carried out at night. <br /> Page 14 <br />
