1 <br />6.0 QUALITY CONTROL AND MANAGEMENT <br />' 6.1 Quality Control During Construction <br />A significant aspect of all geotechnical engineering is the quality control required during <br />' construction to ensure that materials being used are in accordance with the design specifications. <br />Accordingly, construction activities will be observed continuously and tested, as necessary, by experienced <br />' and trained professionals familiar with embankment/fill placement. This will provide the opportunity to <br />detect field conditions, not previously identified, that might necessitate a revision in the design or <br />construction program, and to see that construction is accomplished in accordance with the intent of the <br />1 design. <br />A quality assurance program will be developed and implemented during the construction of the 1 <br />embankment raise and installation of the geosynthetic materials. This will involve representative testing of <br />components of the facility, and on-going assessment of results being achieved. In general, the tests will be <br />split into two categories: <br />1. (_'ontrol Tests: These tests will be carried out on construction materials prior to placement <br />in the facility, to ensure material suitability. <br />2. Record Tests: These tests will be carried out after installation to provide data for <br />assessment of results actually achieved. Record test results will be used as the basis for <br />' confirming compliance with design requirements or modifying procedures, if necessary. <br />Upon completion of the construction, a comprehensive construction report will be prepared which <br />' will include all test results from the quality assurance program and as-built drawings. ~~tr <br />t 5.2 Management Plan <br />On-going monitoring and management of all components of the tailings facility will be an important <br />' .aspect of future operations. Regular inspections of the facility will be conducted to assess the on-going <br />integrity and performance of the primary components, and to identify the onset of any conditions that might <br />compromise the effectiveness of the facility. <br />' Tailings deposition will be conducted in a controlled manner to promote the formation of relatively <br />uniform thin layers of tailings. This will facilitate effective drainage of the tailings so that they can <br />' consolidate and dry prior deposition of additional material and promote development of a stable beach along <br />the embankment and maximize the storage capacity of the facility. <br />Construction activities will incorporate best management practices, including control of fugitive dust <br />and management of stormwater flows. Fugitive dust control will be accomplished by watering traffic <br />' surfaces and disturbed areas prior to and during construction activities. Stormwater management will include <br />installation of silt fences at the toes of embankment slopes and hay bales in drainage paths, as needed, for <br />sediment control. <br />15 <br />
