33. There are two more informal documents from the GFV to the GRPE. One relates to LNG coming from the GRSG for venting and holding time. This was a request from Germany to bring the issue as an ‘environment concern’ to GRPE, but not to have an impact on the adoption of the LNG amendments to R.110. (66-05 and 66-20) The second document is a PowerPoint presentation of this same issue. Mr. Rijnders suggested that Mr. Seisler may be asked to make the presentation to GRPE since he was involved in the LNG TF and participated at the GRSG meeting in April where this issue came up.
