For the Green EMP containers in these number series, on http://www.rrpicturearchives.net/ - dates range from early 2011 up into 2020 in service;
the 6402xx & 6403xx series these are based on are still in use in 2020: http://www.rrpicturearchives.net/showPicture.aspx?id=5388378

Photos date back to early 2011 for both series; http://www.rrpicturearchives.net/showPicture.aspx?id=2803331

It's possible they were delivered in 2010.
