As we mentioned earlier, in the 1999 audit, we did indeed identify the fact that tracking wasn't in place for many of the substances. As Mr. Moffet has said, by the time the 2002 audit came around, they had in fact added a number of substances to the national pollutant release inventory. How comprehensive that is today, I really don't know.
I think it's almost as if...again, without trying to sound like a broken record, if you request from the departments on a substance by substance basis whether it is being tracked under the NPRI and under what conditions, you'll find out pretty quickly which of the releases are being tracked through that mechanism.
At the time of the 1999 audit, many were being reported through the voluntary ARET program.
