NR 182.109(2)(c)(c) For a plan of operation for any facility that includes a composite liner or composite capping layer or that utilizes a geomembrane for a liner or utilizes a geomembrane or geomembrane-GCL for a capping layer, all of the following design details and specifications for the geosynthetic components together with any additional requirements specified by the department for other geosynthetic materials used in significant structural features of the mining waste facility: NR 182.109(2)(c)1.1. A description of the proposed geomembranes, GCLs and other geosynthetics to be used in construction of the facility, including resins and additives, physical properties, bentonite characteristics, chemical resistance properties and potential suppliers. For GCLs, this shall include identification of the geotextile properties and reinforcement. NR 182.109(2)(c)2.2. The design calculations that demonstrate the stability of the facility and its components against failure along potential failure surfaces, such as the leachate collection system and final cover, during operations as well as after closure. Potential failure surfaces considered shall include the interfaces both below and above the geomembrane in the liner and final cover. Potential failure scenarios considered shall include both saturated and unsaturated conditions for the cover. The design calculations may use typical data or specifications from technical literature rather than values from testing of site-specific materials if the sources of the typical data or specifications and the test methods used to generate the data or specifications are cited with the calculations and a safety factor of at least 1.3 is used to assess stability. NR 182.109(2)(c)3.3. The construction methods and supervisory controls for preparing the surface of the topmost lift of compacted clay prior to the installation of a geomembrane or soil barrier layer prior to installation of a GCL. The plan of operation shall propose inspection methods and removal of coarse gravel or cobbles after rolling the topmost lift of compacted clay or soil barrier layer to achieve a smooth surface. NR 182.109(2)(c)4.a.a. The measures to be taken to store and protect all geomembranes, GCLs, and geocomposite drains. NR 182.109(2)(c)4.b.b. The measures to transport geomembrane, GCL, and geocomposite drain panels from storage to the working area. NR 182.109(2)(c)4.c.c. The construction methods to be used to place geomembrane, GCL, and geocomposite drain panels. NR 182.109(2)(c)5.5. The proposed orientation of all geomembrane and GCL panels for the facility liner and capping layer in relation to slope, collection trenches, penetrations, anchor trench and phase boundaries, seaming methods, and phased construction. NR 182.109(2)(c)6.6. The design details of geomembrane and GCL seams and seaming methods, anchor trenches, patches, collars for all penetrations, installation in corners, and leachate collection trenches. The plan of operation shall describe acceptable working conditions for geomembrane, GCL and geocomposite drain installation, installation instructions for working under weather variations and extremes, and criteria for halting or limiting GCL and geomembrane installation. NR 182.109(2)(c)7.7. The proposed methods for testing welds or other joining methods for geomembranes and other components or penetrations if geomembranes used in previously constructed phases are obtained from different manufacturers or are made from different resins. The plan of operation shall also include measures to preserve the edges of geomembranes and GCLs to be joined to future phases and describe measures to repair all geomembrane, GCL and geocomposite drain defects, unacceptable wrinkling, and unacceptable seams. NR 182.109(2)(c)8.8. The construction methods for placing the leachate collection system, sump backfill, and sideslope riser over the composite liner; placement of the first 10 feet of waste materials over the leachate collection system; and placing the subsurface drain layer and rooting zone soils over the composite cap. The measures under this subdivision shall assure that the geomembrane and GCLs are not damaged by construction of soil layers, placement or compaction of wastes, waste consolidation, or mass movements or puncturing of the geomembrane. NR 182.109(2)(c)9.9. A construction quality control plan that will be followed by all contractors preparing the surface of the compacted clay liner or soil barrier layer, constructing the geomembrane liner, or placing drainage blanket. The construction quality control plan shall describe how progress in construction, as well as any variations from the approved plans, will be recorded and reported. The construction quality control plan shall include means for determining and documenting all of the following: NR 182.109(2)(c)10.10. A construction quality assurance plan that will be followed by the registered professional engineer and qualified technician responsible for evaluating the construction and ensuring that the fabrication and installation meet design specifications. The construction quality assurance plan shall include continuous observation of all aspects of geomembrane, GCL, and geocomposite drain installation activities by qualified engineers or technicians. The construction quality assurance plan applicable to liner and cover system components shall include use of nondestructive and destructive testing of seams and samples and shall follow a schedule of tests and associated frequencies in a manner that is consistent with the requirements of s. NR 516.07. The construction quality assurance plan shall include proposed methods of verifying the acceptability of the prepared subgrade, repairs, patches, penetrations, seams, and adaptations by the owner and contractors to unforeseen conditions. NR 182.109(2)(c)11.11. A construction quality assurance plan for conducting a leak location survey on the installed geomembrane. The leak location survey shall be conducted after placement of the leachate collection layer for a composite liner. The quality assurance plan shall include continuous observation of all aspects of the leak location survey testing by qualified professional engineers or technicians. The quality assurance plan shall include use of nondestructive methods to detect, locate, and verify repairs of defects in geomembrane. The quality assurance plan may include electrical resistivity testing or other testing methods acceptable to the department. NR 182.109(2)(d)(d) A contingency plan to prevent or minimize human health and environmental impacts in the event of an accidental or emergency discharge or other condition not anticipated in the feasibility report or plan of operation that does not comply with license conditions or other applicable standards. As a minimum, the contingency plan shall do all of the following: NR 182.109(2)(d)3.3. For the various monitoring programs required by this chapter, indicate threshold levels that, if exceeded, trigger implementation of the contingency plan. NR 182.109(2)(d)4.4. Include a provision for additional monitoring locations, more frequent monitoring, additional sampling parameters, or other types of monitoring in the area of any excessive measurement. NR 182.109(2)(d)5.5. Describe possible accidental or emergency discharges or other unplanned events and identify the corresponding corrective action or alternative action to be implemented if the criteria for action are exceeded.
