NR 106.99(4)(g) (g) The opportunities for material or product substitution.

NR 106.99(4)(h) (h) The opportunities available for support from or cooperation with other organizations.

NR 106.99(4)(i) (i) The actions the discharger has taken in the past to reduce PFOS or PFOA use or discharges.

NR 106.995 NR 106.995 Sampling and laboratory analysis requirements.

NR 106.995(1) (1) The permittee shall collect samples in accordance with the requirements in the permit. The department may require either grab or composite samples as a permit condition. If the permittee uses a composite sampler, an equipment blank is required.

NR 106.995 Note Note: If the permittee uses a composite sampler, it is recommended the permittee contact their department compliance representative prior to sample collection for additional sampling information.

NR 106.995(2) (2) The laboratory performing the analyses on any samples shall be certified for the applicable PFAS compounds in the aqueous matrix by the Wisconsin Laboratory Certification Program established under s. 299.11, Stats., in accordance with s. NR 149.41.

NR 106.995 Note Note: 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.

NR 106.996 NR 106.996 New dischargers or new sources. 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.
