Gwneir y Rheoliadau hyn gan yr Ysgrifennydd Gwladol, wrth arfer y pwerau a roddir gan adran 140 o Ddeddf yr Amgylchedd 2021, a pharagraff 1 o Atodlen 21 i Ddeddf yr Amgylchedd 2021. Dim ond yr Ysgrifennydd Gwladol all arfer y pwerau hyn o wneud rheoliadau i ddiwygio Rheoliadau REACH ac ni all Gweinidogion Cymru na'r Alban eu harfer ar wahân. Fodd bynnag, yn rhinwedd paragraff 3 o Atodlen 21 i Ddeddf yr Amgylchedd 2021 ac Erthygl 4 o Reoliad REACH, rhaid i'r Ysgrifennydd Gwladol ofyn am gydsyniad Gweinidogion Cymru os, ac i’r graddau, y bydd arfer y swyddogaeth gwneud rheoliadau o fewn cymhwysedd datganoledig (o fewn ystyr adran 58A(7) ac (8) o Ddeddf Llywodraeth Cymru 2006).
These Regulations are made by the Secretary of State, in exercise of the powers conferred by section 140 of, and paragraph 1 of Schedule 21 to, the Environment Act 2021. These regulation-making powers to amend the REACH Regulation can only be exercised by the Secretary of State and are not exercisable separately by the Welsh or Scottish Ministers. However, by virtue of paragraph 3 of Schedule 21 to the Environment Act 2021 and Article 4 of the REACH Regulation, the Secretary of State must seek the consent of the Welsh Ministers if, or to the extent that, the exercise of the regulation making function is within devolved competence (within the meaning of section 58A(7) and (8) of the Government of Wales Act 2006).
