The statement shall include construction of leachate collection and transfer lines, side slope risers for leachate pumping, all liner penetrations, collection tanks, manholes, lift stations, lysimeters and leachate head wells.

NR 182.110(4)(4) Construction documentation report. In order to fulfill the construction report requirements of sub. (1), the owner of a waste mining facility shall prepare a comprehensive constructive documentation report for the construction of a new mining waste facility. The report shall contain a detailed narrative describing the construction of the facility in a logical fashion that shall contain, all of the following information, as applicable to the specific design of the facility:

NR 182.110(4)(a)(a) A set of 24-inch by 36-inch engineering plan sheets, or alternative size if approved by the department in writing, that includes all of the following:

NR 182.110(4)(a)1.1. A plan view documenting the constructed grades for the sub-base, sidewalls, leachate collection trench undercuts, and all sub-base appurtenances such as lysimeters and drain pipes, prior to liner placement. Documentation of the grades shall consist of spot elevations taken on a maximum 50-foot grid pattern, with leachate collection trench undercut elevations at least every 25 linear feet. If a total station or laser equipment is used to set elevations, the elevations may be taken every 50 linear feet. The approved sub-base grades shall also be shown for the same area in a clear and legible manner.

NR 182.110(4)(a)2.2. A plan view drawing showing the locations of all the various soil and geomembrane testing performed. Each test location shall be clearly labeled with appropriate identification codes. The plan view drawings shall clearly show any areas where removal and re-compaction of clay was necessary in order to attain the minimum required specifications. For composite-lined and composite-capped mining waste facilities, a plan view drawing shall also clearly show geomembrane panel placement, geomembrane patches and seam repairs, and geomembrane destructive sample locations. Multiple plan views may be shown on a single plan sheet if legibility is not compromised.

NR 182.110(4)(a)3.3. A plan sheet documenting the constructed elevations for the liner system. This plan sheet shall contain spot elevations of the base, sidewalls, and leachate collection trenches. Documentation of grades shall include spot elevations taken on a maximum 50-foot grid pattern, with leachate collection trench elevations taken every 25 linear feet. If a total station or laser equipment is used to set elevations, the leachate collection trench elevations may be taken every 50 linear feet. The approved base grades shall be shown for the same area in a clear and legible manner.

NR 182.110(4)(a)4.4. A plan view drawing showing the constructed base grades as well as the locations and elevations of all leachate collection and transfer piping, manholes, lift stations, culverts, and berms and the location of all unsaturated zone, groundwater, leachate monitoring and cleanout devices, surface drainage features, and other pertinent structures. This information may be shown on the plan sheet required in par. (c) if legibility is not compromised.

NR 182.110(4)(a)5.5. A cross-sections through the constructed area parallel and perpendicular to the base line of the facility. A minimum of 4 cross-sections shall be prepared, 2 of which shall be in each direction. Additional cross-sections shall be prepared as necessary to add clarification. Each of the cross-sections shall show actual and design sub-base and base grade contours, the top of the granular drainage blanket, leachate and groundwater pipe elevations, and the actual base and sub-base contours of adjacent filled areas. The design sub-base and base grade contours do not need to be shown if there is not an observable variation from the design grades.

NR 182.110(4)(a)6.6. A detail drawing, both plan view and cross-sections, of all manholes, lift stations, storage tanks, sumps, and sideslope risers or locations where leachate transfer piping exits the lined area and the secondary containment of these features as well as leak detection monitoring points and other pertinent construction details. At a minimum, these drawings shall show base and top elevations, the invert elevations of all associated piping, pump details, float level elevations, and the extent of recompacted clay placed around and below the structures. If float elevations are not available at the time of submittal of the construction documentation report, they shall be provided to the department when they are available.

NR 182.110(4)(a)7.7. The cross-section details to illustrate all important construction features of the liner, lysimeters, leachate collection trenches and sumps, and sediment control and storm water management systems.

NR 182.110(4)(a)8.8. The drawing details for leachate header lines or drain lines located outside the limits of waste in critical areas of below-ground piping, such as where several pipes cross or meet to illustrate sufficient pipe location and invert information.

NR 182.110(4)(b)(b) A narrative description of important facility design features including all of the following:

NR 182.110(4)(b)1.1. An analysis and discussion of all soil and geomembrane testing work performed. All density and moisture content testing results shall clearly indicate which Proctor curve or line of optimums is applicable to the soil being compacted. Any change in the referenced Proctor curve or line of optimums shall be identified as to when the change occurred and why the change was made. All raw data from the soil and geomembrane testing performed shall be included in an appendix to the construction documentation report unless other arrangements were previously approved by the department. The raw data shall be summarized using a tabulated format. The discussion shall also include the make, model, weight, and foot length of each piece of equipment used to compact clay, if applicable.

NR 182.110(4)(b)3.3. A discussion of how the leak tests were performed on lysimeters and sideslope riser sumps and a discussion of any problems encountered and how they were resolved.
