Section NR 213.09 - General submittal requirements(1) GENERAL. An engineering report and plans and specifications shall be submitted to the department for approval in accordance with s. 281.41, Stats., prior to initiating construction. (a) The department recommends, whenever possible, a preliminary engineering report outlining the project and including any available information required under par. (b) be made prior to submittal of final plans.(b) The engineering report shall outline the entire project and include, at a minimum, the following information: subsurface site conditions, waste sources, waste analysis and waste volume; materials and specifications of the proposed liner required under ss. NR 213.10 and 213.11; compatibility of the waste and proposed liner and estimated life of the liner required under sub. (4); the proposed method of installation, and the equipment and testing methods to be used for quality control both during and after construction.(c) The plans and specifications shall include the existing and finished elevations and adequate details to fully illustrate the proposed installation.(d) When a groundwater monitoring system is required under s. NR 213.08(3), an engineering report and plans and specifications shall be submitted and shall include: a discussion of the installation, the proposed materials to be used, and the method of construction and location of all proposed wells.(2) SUBSURFACE INVESTIGATION. (a) Reports on subsurface site conditions shall include boring logs, particle size distribution and soil classifications for each major lithologic unit and the depths to groundwater and bedrock when encountered. When on-site soil is proposed as the lining material, compaction curves, permeabilities and Atterberg limits shall be established for the soil proposed for the lining material.(b) Sufficient soil borings shall be performed at each proposed lagoon site to adequately define the subsurface soil conditions and depth to groundwater and bedrock at the site. A minimum of 3 borings for the first acre and one boring for each additional acre or portion of an acre shall be performed. The borings should be distributed in a grid pattern over the entire site. In no case may less than 3 borings be performed. The department may require additional borings depending upon the size of the lagoon, proposed liner, waste material, or known or anticipated critical hydrogeologic conditions at the site.(c) All soil borings shall extend a minimum of 10 feet below the proposed base grade of the lagoon, or to groundwater or bedrock, whichever is less.(d) Soil borings shall be performed by or under the supervision of a qualified soil testing laboratory, engineering firm, or other individual or firm which has demonstrated the capability to perform such work.(e) Measurement of the resistance of the soil to penetration and the collection of soil samples shall be performed every 5 feet and at all significant changes in soil type or lithology in each soil boring.(f) All soil samples shall be analyzed for particle size distribution and classified texturally.(g) When required under s. NR 213.08(3), groundwater monitoring wells may be installed in the soil boring holes provided these holes are located adequately to assure representative monitoring of both upgradient and downgradient groundwater conditions.(3) WASTE ANALYSIS. (a) Representative samples of all wastewater, sludge or other materials to be placed in the lagoon shall be analyzed to determine the composition of the samples. Past analyses may be used, provided they are representative of the wastewater, sludge or other materials to be discharged to the lagoon.(b) Sludge shall be analyzed on both a total solids and an extracted pore water basis.(c) The parameters analyzed for may include BOD5, COD, pH, alkalinity, specific conductance, chloride, sulfate, sodium, calcium, magnesium, total dissolved solids, hardness, or any other constituents or properties known or suspected to be detrimental to the integrity of the proposed liner.(d) For all facilities, estimated wastewater characterization shall be provided, along with the basis for the estimates.(4) WASTE AND LINER COMPATIBILITY. (a) Compatibility between the waste and the proposed liner shall be addressed and documented. Prior research or data from similar existing sites shall be included when available. If specific testing is performed, all test procedures used shall be detailed and the results provided.(b) For synthetic and soil-bentonite liners, written confirmation of compatibility, as well as the estimated design life of the liner against the waste in question, shall be provided by the manufacturer of the synthetic liner or bentonite.(c) The department may require controlled long term compatibility testing such as column studies, permeability or immersion tests to determine long-term changes in permeability, soil structure or physical properties of the liner.(5) SAMPLING AND TESTING STANDARDS. (a) Soil samples taken to determine soil classification, particle size distribution or permeability shall be taken in accordance with ASTM D1586 (1984), ASTM D1587 (1983) or ASTM D3550 (1984).(b) Coefficient of permeability of the constructed soil or soil-bentonite liner shall be determined using a laboratory permeability test on hydrated and saturated specimens of the liner material, compacted at the same approximate density as exists in the in-field condition. Tests may be performed on remolded or core samples. The permeability shall be based on stabilized inflow and outflow rates during the test. Separate tests shall be performed using tap water and the wastewater or sludge extract, and the results compared. All preparation work and information detailing the test apparatus shall be submitted along with all results obtained.(c) Particle size analyses to determine particle size distribution of soil samples shall be performed in accordance with ASTM D422 (1972).(d) Plasticity index shall be determined in accordance with ASTM D4318 (1984).(e) Measurement of the resistance of soil to penetration shall be determined in accordance with ASTM D1558 (1984) or ASTM D1586 (1984).(f) Standard proctor densities shall be determined in accordance with ASTM D698 (1978).(g) Soils shall be classified texturally according to the Unified Classification System.(h) In-place density may be determined in accordance with ASTM D2922 (1981) or ASTM D2937 (1983).(i) Other methods of sampling and testing may be approved by the department on a case-by-case basis.Wis.
