South Korea’s Ministry of Environment (MoE) implemented the revised Enforcement Rules of Chemical Control Act[1] (CCA) on April 1, 2021, adopting a new reporting system for enterprises handling hazardous chemical substances (MoE news[2]). The previous off-site impact analysis report (for hazardous chemical substances) and risk management plan (only for chemicals requiring preparation for accidents) were integrated into a single chemical accident prevention management plan to avoid overlaps in submitting required information and expedite authority processing time.
