Continued... <br />ii. The ROC drawing (6 of 6) in Appendix A provides panel numbers for an estimated <br />1,715 panels. There are three different shades of grey text used to label these <br />panels and no legend or note describing the different meanings of these different <br />shades. In addition, the title block refers to Figure 2 in the report text. Besides the <br />fact that a record of construction drawing should be stand alone and should <br />definitely not refer to a figure in a report, the aforementioned figure does not have <br />enough detail to clarify what part of the liner is being certified. <br />Response: <br />The ROC drawing legend has been revised to clarify what panels have been <br />previously certified, are being certified, and will be certified in the future. The <br />revised drawing has been stamped and re-signed by a professional engineer and <br />is attached with this response. <br />Where the title block refers to Figure 2 is located under the "Project" section of the <br />title block. This is part of our title block where the report name is included; should <br />a copy of the drawing ever become separated from the report it can be reunited. <br />The record of construction drawing is a stand-alone drawing as it demonstrates <br />the geomembrane panels that are being certified with this ROC report. <br />The Legend in Figure 2 has also been revised to remove reference to the ROC <br />title and replaced with "Area Certified with this ROC Report". <br />iii. The Division attempted to clarify what is being certified by comparing figures in the <br />weekly reports submitted as Appendix D with ROC drawing 6. The Division could <br />not find a "Weekly Liner Acceptance Form" figure that matched the BOLD labeled <br />panels on ROC drawing 6. Further review of weekly reports SLF, DCF and <br />subgrade acceptance figures provided no clarification either. <br />Response: <br />The maps provided with the weekly reports are used to document a snap shot of <br />progress during construction for liner, SLF, DCF, and subgrade. Some of the maps <br />show areas that will be included in future ROC reports. <br />B. The Division was unable to locate specifications, record of construction drawings or <br />certification reports for the 14 -inch barren solution pipe that the Division understands is <br />intended to be used to pump barren solution from the Carlton ADR (aka ADR1) to the <br />Squaw Gulch Facility in the near future. As this pipeline is a pumped system, it has the <br />potential to operate under pressure, and given its proximity to the edge of the liner, the <br />Division has determined that Rules 7.3.1(5) and 7.3.2(2) apply requiring a certification <br />report prepared by a professional engineer or other appropriately qualified professional <br />that will confirm that the facility (pipeline) was constructed in accordance with the approved <br />design plan. The Division will require submittal of and acceptance by the Division prior to <br />allowing the use of the 14 -inch steel pipe to pump designated chemicals. <br />Amec Foster Wheeler Environment & Infrastructure, Inc. <br />2000 S.
