The CGSB is looking at these issues. They have a B1 to B5 standard in place. The ASTM is looking at the cold flow issues as well. The Europeans are. It looks like the North American standards are going to tighten a bit and the European standards may loosen a bit, and we may have something that is more of a global standard.
There is lots of work being done by the petroleum industry, by our members, by other agricultural organizations like the soybean growers in the U.S., plus the standard-setting bodies that are looking at these issues. There's one thing everybody agrees on, and that is we want to make sure we have a safe fuel that works, that isn't going to cause problems. Hence, there is very close association and work with OEMs, engine manufacturers.
