In reviewing the appropriate elements for a PFOS and PFOA minimization plan for municipal dischargers or primary and secondary industrial dischargers, the department shall consider all of the following: NR 106.99(4)(c)(c) The concentrations of PFOS and PFOA in the effluent, influent, and biosolids or sludge, if applicable and available. NR 106.99(4)(d)(d) The costs of potential PFOS and PFOA minimization plan elements. NR 106.99(4)(e)(e) The environmental costs and benefits of the PFOS and PFOA minimization plan elements. NR 106.99(4)(f)(f) The characteristics of the community in which the discharger is located, if applicable. NR 106.99(4)(h)(h) The opportunities available for support from or cooperation with other organizations.

NR 149.41. NR 106.995 NoteNote: If the EPA Office of Water publishes a 1600 series isotope dilution method for the analysis of PFAS in wastewater, the department recommends use of the EPA method.
NR 106.995(3)(3) The department may reject any sample results if results are produced by a laboratory that is not in compliance with certification requirements under ch. NR 149.

If the department determines that a new source or new discharger may have the reasonable potential to cause or contribute to an exceedance of the PFOS or PFOA standard under s. NR 102.04 (8) (d) 1., the permittee shall install pollution control measures to achieve the standard prior to discharge, and water quality-based effluent limitations for PFOS or PFOA or both that are calculated using the procedure in ss. NR 106.07 (2) and 106.98 (4) and ch. NR 207 shall be included in the permit. NR 106.996 HistoryHistory: CR 21-083: cr.
