In order to ensure that Annex III lists all Union legal acts pursuant to which regulatory processes on chemicals or groups of chemicals are undertaken by competent authorities of the Member States, the ECHA, the EEA, the EFSA, EU-OSHA or the Commission, and in order to keep the common data platform up to date, as soon as new Union legal acts pursuant to which new regulatory processes are established enter into force, or an existing Union legal act is amended to establish new regulatory processes, the Commission shall adopt delegated acts in accordance with Article 28 to amend Annex III by adding those Union legal acts to that Annex, where the Union legal act concerned did not amend Annex III accordingly.
