UIN 77392, tabled on 18 November 2021

To ask the Secretary of State for Environment, Food and Rural Affairs, whether HSE conducted an independent assessment of the existence of alternative substitutes in its assessment of whether to include tetraethyl lead its authorisation list, Annex 14 of UK REACH.

The Health and Safety Executive (HSE) published their draft recommendation of priority substances to be included in Annex 14 of UK REACH (list of substances subject to Authorisation) in August 2021. In recommending these substances, HSE considered evidence that had been submitted to the European Chemicals Agency in relation to tetraethyllead and identified that whilst work is underway to identify alternative substitutes, none are currently available. HSE set out that it may be appropriate to revisit the regulatory approach to tetraethyllead when technical evaluations of potential alternatives are completed. The process for recommending substances for Annex 14 prioritisation is a regular one, so all substances will be reassessed in future prioritisation rounds.
