Question to the Department for Environment, Food and Rural Affairs:

To ask Her Majesty's Government why they decided not to place tetraethyllead on a list of substances “of very high concern”; on what grounds that decision was taken; whether the transition period has been extended for the use of this substance in the fuel for small aircraft; and if so, when that transition period will end.

Tetraethyllead is listed on the UK REACH Candidate list as a substance of very high concern. There is no transition period associated with these obligations under UK REACH.
