EIAs are making what I would suggest would be statements about future activity. In order for me to undertake toxicity work, the mill has to be operational and I have to have some of the materials that they're working with to be able to do the toxicity work. In fact, when I have reviewed them, it has been with respect to their toxicity estimates and whether or not I thought they were reasonable. The models are there, they stay what they are, but frankly, you can't really tell what the toxicity of something is until you have something to expose organisms to.
