Well, certainly I'm going to talk about the gas stations specifically. They accept that as the regulated standard now under current standards. It's not a discussion we've had in terms of whether they think that should be a higher level of tolerance or not, so I'm afraid that I really can't answer that question.
Ultimately, it's up to the government to decide to promulgate a standard, which they've done. That's certainly the standard members now take very seriously and certainly have within their own organizations.
While I'm not privy to all the details of how individual companies respond to that, they take this as a very serious issue. They have compliance programs that in many cases, I'm told, exceed the two-year voluntary standard, with some companies doing it as frequently as annually on a regular basis, and even more.
With respect to the specifics of the tolerance, I don't have a particular view of where members sit on that.
