EPA's November 14, 2024 final unreasonable risk determination for 1,4-dioxane under TSCA § 6(a) may support general causation but does not constitute a discovery event or toll federal or state SOLs. No MDL currently established for 1,4-dioxane personal injury litigation per provided sources. Cross-jurisdictional screening priority: Florida (decedent-exposure 2-year absolute bar); Indiana (dual-track accrual for contribution vs. direct claims); Arkansas (occurrence-rule default with concealed-injury exception).
Rule: Ind. Code Ann. § 34-11-1-2(a); contribution claims accrue only upon cleanup order, per Pflanz v. Foster, 888 N.E.2d 756 (Ind. 2008), No. 36S01-0710-CV-425
Discovery: For direct property damage claims, accrual begins when owner knew or should have known of injury per Wehling v. Citizens Nat'l Bank, 586 N.E.2d 840 (Ind. 1992). For contribution/indemnification claims, accrual delayed until payment obligation is incurred.
Pflanz creates split accrual framework: personal injury/property damage claims trigger under standard discovery rule; cost-recovery claims against prior owners/operators accrue only upon regulatory order or payment. Screen for dual-track exposure dates.
Rule: Ark. Code Ann. § 16-56-105(4) (trespass); occurrence rule governs accrual absent fraud or deliberate concealment, per State v. Diamond Lakes Oil Co., 347 Ark. 618, 66 S.W.3d 613 (Ark. 2002)
Discovery: Discovery rule recognized for inherently concealed injuries; burden shifts to plaintiff to prove tolling by preponderance once facial bar shown. Fraud or deliberate concealment suspends running until discovery or reasonable-diligence discovery date.
Groundwater contamination claims may qualify as 'inherently concealed' triggering discovery rule, but plaintiff bears affirmative tolling burden. No pending revival legislation identified.
Rule: MCL § 767.24(1) general limitation; no claim-type-specific sub-rule identified in provided sources
No active revival window for 1,4-dioxane claims as of September 2026. Baseline 6-year period applies unless superseded by claim-specific statute. EPA's November 2024 unreasonable risk determination under TSCA may support causation arguments but does not toll SOL.
Rule: R.I. Gen. Laws § 9-1-13(a); 1-year period under § 12-12-17 for criminal-procedure revival actions only
10-year general period applies to civil actions per provided source. No environmental-contamination revival window currently in effect. Distinguish § 12-12-17 (1-year) limited to criminal-procedure revival contexts.
Rule: Fla. Stat. § 95.11(3)(a) (injury to person or property founded on negligence); 2-year absolute bar for estate claims per § 733.710, per Comerica Bank & Trust, F.S.B. v. SDI Operating Partners, L.P., 673 So.2d 163 (Fla. App. 1996)
Discovery: Discovery rule applies to negligence claims; 4-year period runs from accrual. Statute of repose may apply to construction/defect claims.
Wrongful death claims limited to 2 years per § 95.11(4)(d). Estate claims against decedents absolutely barred at 2 years from death per § 733.710 with no extension authority. Screen decedent-exposure cases immediately for death dates.
