NR 512.11(2)(2) Geologic cross-sections. Cross-sections shall be constructed through all borings, both perpendicular and parallel to the proposed landfill’s baseline. For a proposed contiguous, horizontal or vertical expansion of an existing landfill, the cross-sections shall be expanded to include all the previous borings for the existing landfill. At least one cross-section shall be constructed parallel to groundwater flow. Where more than one interpretation can be reasonably made when evaluating heterogeneities within unconsolidated deposits, assume that the heterogeneities are continuous. The following information and where applicable, the information required by s. NR 512.14 (2) (b), shall be presented on the geologic cross-sections:

NR 512.11(2)(b)(b) For clarity, a number or symbol shall be used to label major soil units instead of extensive shading. A key shall be provided which contains a description of each major soil unit including geologic description and origin, USCS classification and color.

NR 512.11(2)(c)(c) Boring logs showing the USCS classification and geologic origin of each major soil unit, the results of grain size analyses, Atterberg limits and field hydraulic conductivity tests. The data shall be correlated to the sample location.

NR 512.11(2)(d)(d) Well construction details shown to scale including the well screen and filter pack length, the location of the upper and any lower seals and stabilized water level elevations measured on the same day. Where 2 or more observation wells are presented on a cross-section, a line representing the water table shall be drawn. The date the measurements were taken shall be specified in the key.

NR 512.11(3)(3) Water table maps. At least 2 water table contour maps shall be submitted. One map shall be based on the highest set of monthly water table elevations measured in the observation wells installed at the proposed landfill’s location and the other map shall be based on the lowest set of monthly water table elevations measured in the observation wells installed at the proposed landfill’s location. For each sampling round, all water level elevations shall be measured on the same day. The water table maps shall show all observation wells and the measured water level elevation at each observation well. Any observed variations in flow direction shall be discussed in the narrative of the report. For a contiguous, horizontal or vertical expansion of an existing landfill, the water table contour maps shall be expanded to include the observation wells and measured water table elevations at each observation well for the existing landfill. Inferred contours made beyond the extent of the observation well field shall be shown with dashed lines. If 3 or more bedrock wells are installed, a bedrock piezometric map shall be prepared.

NR 512.11(4)(4) Bedrock map. If at least 3 borings have been extended into bedrock, a bedrock contour map shall be prepared from specific and regional data.

NR 512.11(5)(5) Flow net. A flow net shall be constructed parallel to the direction of groundwater flow to show the distribution of recharge and discharge.

NR 512.12(1)(1) Industrial wastes. Unless otherwise approved, the physical and chemical characteristics of any high volume industrial waste such as a foundry process waste, papermill sludge, utility coal-ash waste, and other non-municipal waste that is anticipated to individually constitute more than 5% of the total proposed design capacity and leachates shall be analyzed and described. When more than one waste is generated, testing shall be performed on each waste stream. All leaching tests shall be done in accordance with published test procedures. Physical tests shall be done in accordance with ASTM standards or published test procedures. All testing procedures shall be documented. The proposed testing program including the leaching test method, the leaching media, the parameters to be analyzed for and the detection limits for each parameter specified should be discussed with the department prior to initiation of the work. Actual field leachate data may be substituted for chemical characterization data of an industrial waste if the data are from an existing monofill that contains waste similar to that which is to be placed into the proposed landfill and if approved in writing by the department.

NR 512.12(2)(2) Municipal wastes. Actual field leachate data from existing landfills of similar size, design and waste type or an estimate of the anticipated leachate strength and quality available from department files shall be included for all landfills for the disposal of municipal solid waste.

NR 512.12(3)(3) Leachate generation. The estimated daily volume of leachate that will be collected during operations and after closure shall be calculated. Unless otherwise approved by the department, the following rates shall be used to calculate the leachate volumes:

NR 512.12(3)(a)(a) A minimum of 6 inches per year shall be used for all unclosed areas of the proposed limits of filling for landfills that will have a composite liner and a minimum of 4 inches per year shall be used for all unclosed areas of the proposed limits of filling for landfills that will not have a composite liner.

NR 512.12(3)(b)(b) One inch per year shall be used for all closed areas of the proposed limits of filling for landfills that will have a composite cap and a minimum of 3 inches per year shall be used for all closed areas of the proposed limits of filling for landfills that will not have a composite cap.

NR 512.13(1)(1) Locational criteria and performance standards. A demonstration that the proposed landfill will meet the locational criteria and performance standards under s. NR 504.04. For a new CCR landfill or an expansion of a CCR landfill, all of the following also apply:
