EPA opens 60-day public comment on updated draft risk calculation memorandum for formaldehyde under TSCA

EPA released an updated draft Risk Calculation Memorandum for formaldehyde under TSCA and opened a 60-day public comment period (noted as open until February 2, 2026). This is a technical support/analytical document that can influence how EPA quantifies and characterizes risk in the formaldehyde TSCA risk evaluation, which in turn can affect downstream risk management decisions and stakeholder engagement strategies. Compliance teams should review the draft methodology and submit comments if assumptions, exposure parameters, or calculation approaches affect their uses or conditions of use.
