Wis. Stat. § 283.82
in effect(1) The department shall oversee, set technical standards for, and regulate the application of sewage sludge to land.
(2) No city, village, town, or county may prohibit, through zoning or any other means, the application of sewage sludge to land if that application complies with this section and rules promulgated under this section.
(3) A city, village, town, or county may regulate the application of sewage sludge to land if the regulation is identical to regulations of the department under sub. (1).
(4)
(a) The department shall include limitations or conditions for perfluoroalkyl and polyfluoroalkyl substances in a permit for the land application of sewage sludge. If the average of at least 2 sample results exceeds a 20 ug/kg concentration for perfluorooctanoic acid and perfluorooctanesulfonic acid combined, the department shall include a limitation or condition on perfluoroalkyl and polyfluoroalkyl substances, unless there is an enforcement standard promulgated under ch. 160 for perfluorooctanoic acid and perfluorooctanesulfonic acid. The department may require groundwater monitoring as a condition of the permit.
(b) No later than August 6, 2026, the department shall issue a general permit that requires perfluoroalkyl and polyfluoroalkyl monitoring conditions for sewage sludge that will apply to all permittees with valid permits on April 8, 2026, that do not have limitations or conditions addressing perfluoroalkyl and polyfluoroalkyl substances. The general permit shall specify monitoring frequencies, as determined by the department. The department shall modify an individual permit as provided under par. (a) if sample results conducted under the general permit exceed a 20 ug/kg concentration for perfluorooctanoic acid and perfluorooctanesulfonic acid combined. Nothing in this paragraph alters the procedures, requirements, or authorities to which the permittee or department are entitled under any other provision of law. This paragraph does not apply to issuance or renewal of permits that comply with par. (a). The general permit issued under this paragraph is valid until all individual permits issued under this section comply with par. (a).
