NR 538.06(2) (2)Initial characterization. A representative sample of each industrial byproduct shall be properly characterized prior to beneficial use to determine its eligible uses under s. NR 538.10. Samples shall be obtained at the point of accumulation nearest to where the byproduct is generated . A case-specific approval under s. NR 538.09 may be required by the department if the byproduct is subject to any deliberate post-accumulation processing, excluding mechanical size reduction or sorting and the application of water to improve handling or as dust suppression.
NR 538.06(3) (3)Characterization methods.
NR 538.06(3)(a) (a) General. The limits of detection used in the characterization shall be at or below the concentrations listed in ch. NR 538 Appendix, Tables 1 to 3 for each parameter.

All material sampling, total elemental analyses, and analyses of elutriate from leach testing shall be performed using EPA SW-846 methods, unless alternate methods are otherwise approved by the department in writing. The generator shall report the limit of detection and the limit of quantitation with the sample results. If a substance is detected below the limit of quantitation, the detected value with the appropriate qualifier shall be reported.

NR 538.06(3)(d) (d) Bulk analysis. All industrial byproducts, except byproducts to be used as a soil or plant additive in accordance with s. NR 538.10 (5), shall be analyzed using a bulk analysis for the parameters in ch. NR 538 Appendix, Table 2, unless another analytical method is approved by the department in writing.
NR 538.06(3)(e) (e) Flue gas desulfurization analysis. All flue gas desulfurization materials to be marketed and used as soil or plant additives in accordance with s. NR 538.10 (5) shall be analyzed using a total elemental analysis for the parameters in ch. NR 538 Appendix, Table 3, unless another analytical method or parameters are approved by the department in writing.
NR 538.06(3)(f) (f) Select foundry sand. Generators may request that the department designate their foundry industrial byproducts as select foundry sand with their initial certification notification under sub. (1) (a) or recharacterization under sub. (5) provided they submit supporting documentation to the department demonstrating that the foundry byproducts meet the definition under s. NR 538.03 (12m) and have been determined to contain less than the concentration specified for the parameters listed in ch. NR 538 Appendix, Table 1, Column B. Supporting documentation shall include evidence of segregation which may include process flow diagrams, written material handling and segregation procedures, or byproduct management summaries. If the department determines that the foundry byproduct meets the definition, the department shall reply with a written concurrence of the designation within 10 business days provided the applicant meets the applicable criteria of this chapter.
