Newmont-Cripple Creek&Victor Gold Mine <br /> Technical Specification No.02200.1)OCX ■ <br /> Squaw Gulch VLF <br /> Project No.475.0106.006 <br /> June 15,2016 <br /> all grade markers under supervision of CQA Monitor after verification <br /> measurements have been approved by MANAGER and CERTIFYING ENGINEER and <br /> will backfill holes with Drain Cover Fill. Areas with deficient thickness shall be <br /> reworked by CONTRACTOR, until acceptable measurements are obtained. If <br /> MANAGER or CERTIFYING ENGINEER suspects the occurrence of any damage to the <br /> underlying geosynthetics, MANAGER will instruct CONTRACTOR to remove Drain <br /> Cover Fill to expose the geosynthetics. CONTRACTOR shall uncover, repair any <br /> observed damage of the underlying geosynthetics, in accordance with the repair <br /> requirements of Sections 02776.0 and 02777.0 of these SPECIFICATIONS and <br /> recover, at no cost to CC&V. <br /> 10. CONTRACTOR will provide adequate illumination as approved by MANAGER, if <br /> Drain Cover Fill placement is carried out at night. A minimum of 2-foot candles <br /> measured at the synthetic liner shall be used when Drain Cover Fill placement is <br /> carried out at night <br /> I. Pipe Bedding Material <br /> 1. Pipe bedding material shall be placed around the CSP as shown on the drawings. <br /> 2. For piping external to the valley leach facility, CONTRACTOR shall compact the Pipe <br /> Bedding Material requiring compaction to at least 95 percent of the maximum dry <br /> density as determined by the Standard Proctor density test (ASTM D698), and a <br /> moisture content 3 percent below and 3 percent over the optimum moisture <br /> content. <br /> 3. CONTRACTOR shall place Pipe Bedding Material in maximum 12-inch loose lifts. <br /> Pipe Bedding Material will be worked under pipe haunches by hand to provide <br /> uniform support of the CSP. <br /> 4. Native material used for backfilling CSP excavation shall be placed in 12-inch to 18- <br /> inch loose lifts, and compacted by wheel rolling with light, rubber tired or other <br /> light compaction equipment, as approved by CERTIFYING ENGINEER. <br /> J. Granular Filter Material <br /> 1. Granular Filter Material shall be placed beneath the Riprap as shown on the <br /> drawings. <br /> K. Bedding Fill <br /> 1. Bedding Fill shall be placed within the limits of the valley leach facility as shown on <br /> the DRAWINGS. <br /> 2. CONTRACTOR shall place and compact the Bedding Fill in loose lifts such that the <br /> compacted lift thickness is a minimum of 12-inches. CONTRACTOR shall condition <br /> the Bedding Fill to allow a surface that does not cause rutting or other deleterious <br /> effects. The moisture content and density shall be uniform throughout the lift. If a <br /> Page 19 <br />
