Notes:
1 - Column A -Industrial byproducts that have concentrations below these standards may be used as geotechnical fill no less than 3 feet from the water table at the time of placement in accordance with s. NR 538.12(2) (b), or no less than 5 feet from the water table when used for nonmetallic mine reclamation under s. NR 538.10(2) (f). Standards are based on the enforcement exceedance values in s. NR 140.10 or recommended standard updates from the Wisconsin department of health services.
2 - Column B -Industrial byproducts that have concentrations above Column A but below Column B may be used as geotechnical fill no less than 5 feet from the water table at the time of placement in accordance with s. NR 538.12(2) (c). Standards are based on 5 times the enforcement exceedance values in s. NR 140.10.

Notes:
Values are derived from the NRCS Conservation Practice Standard Code 333, "Amending Soil Properties With Gypsum Products," June, 2015, screening values or ch. NR 720 Background Threshold Values for lead, manganese and zinc which have background values exceeding the NRCS screening values. Mercury values are based on the ch. NR 720 Direct Contact Remedial Concentration Limits (RCLs).

Notes:
1 - Byproducts intended for use as agricultural liming agents must contain concentrations less than the values listed in s. NR 204.07(5) (c).
2 - Byproducts intended for use as part of a nonmetallic mine reclamation project must either be designated as oselect foundry sand" by the department under s. NR 538.06(3) (f) or contain concentrations less than the values listed in Appendix, Table 1, Column A.
3 - Table 1 contains numeric standards under Column A and Column B. The standards under Column B determine the eligible uses under s. NR 538.08 and the standards under Column A determine the separation to groundwater for geotechnical fill uses under s. NR 538.10(2).
4 - Select foundry sand must contain less than the concentration specified for the parameters in Table 1, Column B as required under s. NR 538.03(12m).
