Rougeau, Lucas v. Ahlstrom Rhinelander, LLC
785 F.Supp.3d 438
W.D. Wis.2025Background
- Plaintiffs, Wisconsin citizens and property owners in Oneida County, sue several corporations for contamination caused by per- and polyfluoroalkyl substances (PFAS) from the Rhinelander Paper Mill (formerly operated by Wausau Paper, now by Ahlstrom) and PFAS manufacturers (3M and BASF).
- Plaintiffs allege waste containing PFAS from the paper mill was improperly disposed of by being spread on local farmland, leaching into plaintiffs’ properties and private wells.
- Defendants Ahlstrom, Wausau Paper, and 3M moved to dismiss the case or individual claims on various grounds, including lack of personal jurisdiction and failure to state a claim.
- Plaintiffs assert a range of theories: design defect, failure to warn, negligence, private nuisance, trespass, and strict liability for abnormally dangerous activity.
- The court evaluates the motions to dismiss under the standard that all well-pleaded facts are viewed in the plaintiffs’ favor at the pleading stage.
- The district court denies all motions to dismiss except as to plaintiffs’ trespass claims against 3M.
Issues
| Issue | Plaintiff’s Argument | Defendant’s Argument | Held |
|---|---|---|---|
| Personal jurisdiction over Ahlstrom Holdings | Holdings did business in WI by owning/operating the mill applying PFAS sludge. | Holdings is just a parent; contacts based on subsidiaries are insufficient. | Motion to dismiss denied; allegations sufficed. |
| Proximate cause (3M) | 3M’s PFAS foreseeably ended up contaminating land/water. | Mill's decision to apply sludge was a superseding cause breaking the chain. | Not pleaded out on causation; defense premature. |
| Statute of repose (3M strict liability) | PFAS represented as lasting >15 years; discovery rule applies. | Claims barred by 15-year limit; PFAS phased out years ago. | Dismissal inappropriate at this stage; factual issue remains. |
| Strict liability for abnormally dangerous activity (Ahlstrom, Wausau) | Land application was abnormally dangerous, high risk, and uncommon. | Strict liability applies to activities, not substances like PFAS. | Sufficiently pleaded as an abnormally dangerous activity. |
| Design defect (3M) | Alternative, safer non-PFAS designs were feasible. | PFAS are essential ingredient; no feasible alternative. | Claim survives dismissal; sufficient at pleading stage. |
| Failure to warn (3M) | 3M didn’t warn about PFAS risk; warnings could reduce harm. | Paper mills knew of risks—warning wouldn’t have changed conduct. | Sufficiently alleged; survival at pleadings. |
| Trespass (intentional/negligence, 3M and Wausau) | Wausau intended/forsaw result; 3M responsible as manufacturer. | No intent/allegation that 3M caused or intended entry of PFAS; passage out of possession severs liability. | Trespass dismissed as to 3M; survives as to Wausau at pleadings. |
| Nuisance (all defs) | Defendants caused loss of use/enjoyment of property via PFAS. | No intent or knowledge of property invasion; not responsible for groundwater. | Intentional nuisance sufficiently pleaded; survives dismissal. |
