Newmont-Cripple Creek&Victor Gold Mine <br /> Technical Specification No.02776-O.DOCX ■ <br /> Squaw Gulch VLF <br /> Project No.475.0106.006 <br /> April 08,2016 <br /> D. CONTRACTOR shall not deploy more geomembrane field panels in one day than can <br /> be seamed during the day of deployment. <br /> E. Geomembrane deployment shall proceed between ambient temperatures of fourteen <br /> degrees (14' F) Fahrenheit to one-hundred degrees (100o) Fahrenheit. Geomembrane <br /> placement shall not be done during any precipitation, in the presence of excessive moisture <br /> (e.g., fog, rain, dew) or in the presence of excessive winds, as determined by the CQA <br /> Monitor. <br /> F. Following the installation of the geomembrane, an examination of the entire surface <br /> shall be conducted to detect potentially harmful rocks or other objects. Any such <br /> objects will be removed and the geomembrane repaired by the CONTRACTOR, at no <br /> cost to CC&V. <br /> 3.6. Factory Seams <br /> MANAGER and CERTIFYING ENGINEER may require CONTRACTOR to test up to as much as <br /> twenty percent (20%) of factory fusion welds (non-destructive air pressure test) in the field to <br /> verify factory test results. Additional testing at CONTRACTOR's expense will be required if failed <br /> tests are obtained in the field. <br /> 3.7. Field Seams <br /> A. Seam Layout <br /> 1. Seams shall be oriented parallel to the line of maximum slope, i.e., <br /> oriented down, not across the slope. In corners and odd-shaped <br /> geometric locations,the number of field seams shall be minimized. <br /> 2. No horizontal or base T-seam or tie-in seams shall be closer than five <br /> (5) feet from the toe of the slope. Seams shall be aligned to prevent <br /> wrinkles and "fish mouths." If a fish mouth or wrinkle is found, it shall <br /> be relieved and capped. <br /> 3. Panels of geomembrane will have sufficient overlap provided to allow <br /> peel tests to be performed on the seam. <br /> B. Seaming Method <br /> 1. The procedure used to temporarily bond adjacent panels together shall <br /> not damage the geomembrane; in particular, the temperature of hot <br /> air at the nozzle of any spot welding apparatus shall be controlled such <br /> that the geomembrane is not damaged. <br /> 2. CONTRACTOR shall use double fusion welding as primary method of <br /> seaming adjacent field panels. <br /> Page 13 <br />
