Editor's Note: This article was originally published in November 2024 to analyze the proposed handling limits for ten toxic chemicals newly designated in August, and was updated on 11 December 2024 to introduce the finalized version.
By the MoE Announcement No. 2024-257 issued on 11 December 2024, South Korea's MoE adopted the proposed handling quantity limits for 10 newly designated toxic substances (Given No. 2024-1-1213 ~ 2024-1-1222). Besides, the chemical name and/or CAS number of 2 toxic chemicals (Given No. 2017-1-762, Given No. 2022-1-1095) previously listed have been updated to align with their updates in the Toxic Chemical Substances List made in August 2024.
According to K-CCA and the Regulation, for a target chemical, exceeding the upper handling limit requires submitting the Grade 1 chemical accident prevention management plan, while the Grade 2 chemical accident prevention management plan can apply if it only exceeds the lower handling limit.
The updates came into force immediately. The MoE announcement is available here.
Proposed Draft in November 2024
On November 12, 2024, South Korea’s Ministry of Environment (MoE) initiated a public consultation on the draft amendments to the Stipulated Quantities for Toxic Substances, Restricted Substances, Prohibited Substances, and Substances Subject to Authorization. Consultation will be due by December 2, 2024.
The draft amendments include:
Proposed handling quantity limits for 10 toxic substances (Given No. 2024-1-1213~ 2024-1-1222), which were newly designated in August 2024 (CL news).
Proposed updates to the chemical name and/or CAS number of 2 toxic chemicals in the Regulations to align with their updates in the Toxic Chemical Substances List made in August.
Under K-CCA, toxic substances, restricted substances, prohibited substances and the substances subject to authorization are required to submit a chemical accident prevention management plan if exceeding the corresponding handling limits. The concerned chemical lists are attached to the Stipulated Quantities for Toxic Substances, Restricted Substances, Prohibited Substances, and Substances Subject to Authorization, including Annex 1 for toxic substances, Annex 2 for restricted substances, and Annex 3 for prohibited substances. As for the substances subject to authorization, eleven candidate substances for authorization under K-REACH have been proposed, including benzene, bisphenol A, DBP, BBP, etc. (CL news). Currently, no substances are on the Authorization List.
This time the proposed amendments to the Regulation are for Annex 1 toxic substances. Details are available here.
