I'm making a presentation on this on Thursday.
Essentially, the problem with TOSCA is that the U.S. EPA uses other companies' data, as well as the notifiers' data, to make a decision. It's because there are third-party data involved, which may be confidential, that they have trouble sharing their assessments. It's a complex problem. It's not necessarily the original notifiers' data. We've had exchanges of data with the U.S. But this situation has posed a problem on the health side, in understanding their assessments.
