47. The expert from EUROMOT introduced GRPE-59-09 proposing to develop under the 1958 Agreement a new Regulation on retrofit aftertreatment systems for engines used in NRMM and agricultural tractors with respect to the emissions of pollutants. GRPE welcomed in principle the proposal, but noted a study reservation by Italy regarding safety risks of such systems. The expert from EUROMOT volunteered to prepare for the next session of GRPE a more detailed document on the scope of the proposal.

48. The expert from the Netherlands presented a similar proposal to set up a test procedure for retrofit particulate traps (GRPE-59-20) of heavy duty vehicles. GRPE noted a number of comments supporting the initiative, but also the need to consider different emissions levels.

49. Following the discussion, GRPE agreed to establish, under the chairmanship of Mr. Barbé from the Netherlands, an informal group on Retrofit Emission Control devices (REC) dealing with both aftertreatment systems and diesel particulate filters intended to be fitted as retrofit systems on heavy duty vehicles and NRMM. In this respect, the GRPE Chairman expressed his intention to seek the consent of WP.29 at its March 2010 session. He invited the experts from the Netherlands, EUROMOT and OICA to prepare for the next GRPE session a proposal for the terms of reference and rules of procedures of the informal group. The expert from AECC volunteered to provide the secretariat servicing of the new informal group.
