Right. Are we making a difference?
We have implemented management measures for each of the substances declared toxic. Some of those have been in place for long enough that we can say yes, we're making a difference. Some of those have not been in place long enough to know whether we're making a difference or not.
I know this is not going to be a satisfactory answer, but what I propose is to provide the committee later in the summer, upon your return--and this is not an attempt to hide it--with a breakdown of the trends in emissions and use of each of the substances over time, and in addition an indication of when the CEPA management measure came into place, because we don't want to attribute causality; the emissions may have gone down for some other reason. We need to be careful about attributing causation to a CEPA measure. That's something we need to be constantly aware of--that we don't do something for no reason or conclude that something was successful, when in fact it may not have had an impact. But I can commit to providing you with that information towards the end of the summer.
