Draft new Regulation on uniform provisions concerning the approval of Retrofit Emission Control Devices (REC) for heavy duty vehicles, agricultural and forestry tractors and non-road mobile machinery equipped with compression-ignition engines. GRPE has requested a formal draft for June 2013.
28. The Chair of the informal group on REC reported on the progress made (GRPE-65-38), focusing in particular on the draft regulation on REC aimed to illustrate the state of play of the informal Group on REC (GRPE-65-18). Having reported that the draft is almost finalized, he expressed his confidence about the possibility to find a solution to the few outstanding issues in the next REC meeting. On NOX emission limits, he reported that, notwithstanding an agreement on a 60 per cent reduction when the REC system is evaluated over the World-wide harmonized Heavy duty Test Cycle, there is still discussion between 60 per cent and 70 per cent for the limit concerning non-road mobile machinery. On direct NO2 emissions, he explained that the definition of the maximum increase compared to the level recorded when no REC is fitted is still open (20 per cent versus 30 per cent).
29. The expert from Germany clarified the readiness to compromise on a 60 per cent reduction on NOX emissions, but he also underlined the need to stick to the 20 per cent maximum increase for NO2. In order to assure the possibility of an informed decision, the expert from the EC encouraged all Contracting Parties to contribute to the discussion with the provision of technical information justifying their positions.
30. Willing to propose text offering solutions based on the national experience, the expert from France pointed out the need to address properly issues related with the conformity of production (stressing the importance to make sure that the retrofitter is responsible for the installation of the equipment) and in-service check. Sweden supported this comment and also offered assistance based on lessons being learned in the national context. The Chair of the REC group welcomed these proposals.
31. GRPE requested the REC informal group to submit an updated version of the draft UN Regulation, so that the secretariat can prepare an official document for the next GRPE session, in June 2013. GRPE also noted the intention of the informal group to submit an informal proposal for an amendment 01 at the same time. The next REC meeting will take place in Bern (Switzerland) on 19 and 20 February 2013. The group should also meet in conjunction with the next GRPE session, in June 2013.
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.
