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.
The hazardous chemical substances under CCA refer to
toxic chemicals (so far 1008 types);
chemicals subject to authorization (haven’t been designated);
restricted chemicals (13 types);
prohibited chemicals (60 types); and
chemicals requiring preparation for accidents (97 types).
The 97 chemicals requiring preparation for accidents and their handling limits for submitting the management plan were specified in Appendix 3-2[3] of the revised CCA Enforcement Rules, which was previously listed in the Appendix 10 (amended by MoE Announcement No. 2021-75). For other hazardous chemical substances, their handling limits were published by the MoE Announcement No. 2021-51[4]. Each hazardous chemical substance is indicated with the lower and upper handling limit, exceeding which requires submitting corresponding Grade 2 or Grade 1 chemical accident prevention management plan.
Basically, a chemical accident prevention management plan should include a list of substances handled and their hazards information, a safety management plan, and an internal emergency response plan regarding accident response and first aid. For Grade 1, which is of higher risks, external emergency response plans for protecting residents, e.g. avoidance plans, should also be added.
The National Institute of Chemical Safety[5] (NICS) is responsible for reviewing the chemical accident prevention management plan and conducting on-site inspections.
