In paragraph 4.4.1., replace “markings” with “approval mark”.
In paragraph 9.1., delete from the proposal (i.e. keep the paragraph in its current form).
79. The Chair of GRBP presented draft amendment proposals contained in documents ECE/TRANS/WP.29/2021/3, ECE/TRANS/WP.29/2021/10 and Rev.1, ECE/TRANS/WP.29/2021/11 under agenda item 4.6.8 to 4.6.10., to amend UN Regulations Nos. 41, 141 and 142.

5. The experts from EC, ETRTO and OICA reported on their studies on sound level limits (GRBP-73-23, GRBP-73-11 and GRBP-73-25, respectively). To coordinate such initiatives, GRBP decided to establish a taskforce (TF) and sought a volunteer among the experts from Contracting Parties to take the leadership of TF, while OICA agreed to act as secretary. GRBP considered that TF should address the sound level limits of UN Regulation No. 51 and, at a later stage, No. 41. To kick-off the TF activities without delay, the Chair pointed out that he could take the lead of TF on a temporary basis, if needed.

5. The experts from EC, ETRTO and OICA reported on their studies on sound level limits (GRBP-73-23, GRBP-73-11 and GRBP-73-25, respectively). To coordinate such initiatives, GRBP decided to establish a taskforce (TF) and sought a volunteer among the experts from Contracting Parties to take the leadership of TF, while OICA agreed to act as secretary. GRBP considered that TF should address the sound level limits of UN Regulation No. 51 and, at a later stage, No. 41. To kick-off the TF activities without delay, the Chair pointed out that he could take the lead of TF on a temporary basis, if needed.
