If I'm using those other industrial applications under the mining act and others, that's not left up to other authorities; it's explicitly said what the post-use level of remediation must be. Mining effluent, potential acid rock drainage, and those types of issues are toxic in nature but not even anything in the stratosphere of the stuff we're talking about here. I don't know why in this act it seems more open than it would be in another act under Parliament.
