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 /> Seams will be tracked according to the welding apparatus and the machine <br /> operator. The following procedures shall apply whenever a sample fails the <br /> field destructive test: <br /> 1. CONTRACTOR can retrace the welding path to an intermediate <br /> location (at a minimum of ten (10) feet from the location of the failed <br /> test in both directions), at CERTIFYING ENGINEER discretion, and take <br /> a small sample for an additional field test. If this test passes, then the <br /> seam shall be capped between the two passing locations. If the test <br /> fails, in either direction, the tracking process shall continue until a <br /> passing area is found. <br /> 2. Over the length of seam failure, CONTRACTOR shall either cut out the <br /> old seam, reposition the panel and reseam, or cap the failing area, as <br /> required by CERTIFYING ENGINEER. <br /> 3. If the area is reseamed, additional destructive field test(s) shall be <br /> taken within the reseamed area. The reseamed sample shall be found <br /> acceptable if test results are approved by CERTIFYING ENGINEER. If <br /> test results are not acceptable, this process shall be repeated until the <br /> reseamed length is judged satisfactory by MANAGER and CERTIFYING <br /> ENGINEER. <br /> 4. Samples taken as the result of failed tests do not count toward the <br /> total number of destructive tests required. <br /> F. CONTRACTOR shall document all actions taken in conjunction with destructive <br /> test failures, with CERTIFYING ENGINEER providing Quality Assurance <br /> documentation. <br /> G. Failing seam lengths which were capped shall be non-destructively tested as <br /> described in Section 3.08. <br /> 3.10. Defects and Repairs <br /> A. All seams and non-seam areas of the geomembrane shall be observed by CQA <br /> Monitor for defects, holes, blisters, undispersed raw materials, and any sign of <br /> contamination by foreign matter. The surface of the geomembrane shall be <br /> clean at the time of observation. The geomembrane surface shall be brushed, <br /> blown, or washed by CONTRACTOR if the amount of dust or mud inhibits <br /> inspection. MANAGER and CERTIFYING ENGINEER shall determine if cleaning <br /> of the geomembrane is needed to facilitate observation at no additional cost <br /> to CC&V. <br /> B. Each suspect location in seam and non-seam areas shall be non-destructively <br /> tested as determined appropriate by CQA Monitor, in the presence of CQA <br /> Page 19 <br />
