Exhibit 15 -1 provides the standard <br />specifications for 30 -mil non - reinforced PVC geomembrane liner used in buried <br />applications in accordance with ASTM D 7176. <br />Exhibit 15 -1 PVC 30 mil Geomembrane Liner Saecifications Used in Buried Applications <br />Prior to installation of the liner, a QC inspector will verify that the surface bedding of <br />the liner has been smoothened and freed of all sharp rocks (all rock and stone greater <br />than 1 inch diameter), objects, vegetation, and other miscellaneous debris. <br />Immediately prior to the placement of backfill, the geomembrane, seams, and non - <br />seam areas will be visually inspected by a QC inspector for defects, holes, or damage <br />due to weather conditions or construction activities. At the QC inspector's discretion, <br />the surface of the geomembrane liner will be brushed, blown, or washed as necessary <br />if the amount of dust, mud, or foreign material inhibits inspection or functioning of <br />the overlying material. All damage to the geomembrane liner will be repaired prior to <br />the placement of backfill. Detailed QA /QC requirements are provided in the technical <br />specifications provided in the design for DRMS review and approval. Technical <br />specifications are included as Attachment S. <br />Denison will provide a certification by a professional engineer or other appropriately <br />qualified professional that will confirm that the facilities were constructed in <br />accordance with the approved design plan. <br />C \ Users \cwoodward\Desktop \Sundays \FINAL - Environmental Protection Plan Sunday Mines Revised January 2012 docx <br />15 -1 <br />
