Schulte said a German delegation looked into the GRPE informal document (doc. REC-14-03) and mainly changes to structure, wording (for consistency) and minor additions were made.

Schulte presented the outcome of the German review (doc. REC-14-06). The suggested changes to the REC draft were considered in detail. For the agreed changes, please consult the working document as the outcome of the REC-14 meeting (doc. REC-14-14). Newly added provisions to the draft that would exclude ‘double retrofitting’ were eliminated for the time being (version 00).

The group reviewed the current version of the working document. Changes to the content of the document that were agreed by the group were accepted in the document. The diagram in annex 8 will have to be redrafted; Schulte will be asked to do this.

The document is now uploaded in 2 versions: one with all tracked changes and suggestions from this REC-14 meeting (doc. REC-14-13) and one as a clean copy (doc. REC-14-14). The latter version REC-14-14 will be the basis for the formal contribution to GRPE.

34. Following an overview on the work of the REC group (GRPE-66-42), the Chair of the REC group illustrated ECE/TRANS/WP.29/GRPE/2013/6, a proposal for a new UN Regulation on REC, as well as: (i) GRPE-66-28, superseding GRPE-66-06 and modifying ECE/TRANS/WP.29/GRPE/2013/6 to introduce limit values and to include a set of flow charts in its Annex 8; and (ii) a draft proposal for the 01 series of amendments to the UN Regulation on REC (GRPE-66-07). These texts aim at facilitating the improvement of the ambient air quality via the reduction of the emissions of particulate matter and/or NOX. They address the emissions of NO2 via four classes of systems. The only outstanding issue for the 01 series of amendments concerns the NO2 emission requirements of traps that allow for a restricted increase of the direct emissions of NO2 (GRPE-66-08).

35. GRPE adopted ECE/TRANS/WP.29/GRPE/2013/6, as amended by GRPE-66-28, and requested the secretariat to submit the resulting proposal to WP.29 and AC.1, for consideration at their November 2013 sessions.

36. GRPE also requested the REC informal group to submit an updated version of the first amendment to the UN Regulation on REC (GRPE-66-07), reflecting the updates emerging from further discussions, so that the secretariat can prepare an official document for the GRPE session of January 2014.
