4.9.1. | Proposal for Supplement 8 to the 05 series of amendments to UN Regulation No. 49

The European Commission informed AC.3 that this proposal is not ready for voting. A new document is being prepared with a vote on the amended proposal envisioned for the June 2015 session of the World Forum.

66. On item 4.9.1 (Regulation No. 49), WP.29 noted that GRPE was expected to review ECE/TRANS/WP.29/2014/74 together with WP.29-164-03 and to revert back to WP.29 and AC.1 at their March or June 2015 sessions with a revised document.

4. (b) | UN Regulation No. 49 and UN Regulation on Retrofit Emissions Control devices (REC)

20. The expert from OICA presented GRPE-69-08 introducing a proposal (ECE/TRANS/WP.29/GRPE/2014/12 as amended by GRPE-69-07-Rev.1) for a new Supplement to UN Regulation No. 49 (i) harmonizing the provisions on On Board Diagnosis Threshold Limits (OTLs) with those of the EU, (ii) deleting the urea consumption motoring obligation as well as improving definitions, (iii) modifying the operating sequence definition for stop-start and hybrid vehicles and (iv) introducing an alternative service mode for LNG dual-fuel vehicles. GRPE adopted ECE/TRANS/WP.29/GRPE/2014/12 as amended by GRPE-69-30 (containing GRPE-69-07-Rev.1 as well as the correction proposed by the expert from NGV Global) and reproduced in Addendum 1 to this report. GRPE requested the secretariat to submit it to WP.29 and AC.1, for consideration at their November 2014 sessions as Supplement 8 to the 05 series of amendments to Regulation No. 49. The expert from the United Kingdom noted that the proposal didn’t comply with the transitional provisions guidelines by WP.29 and would have to be amended at a later stage accordingly.
