so basically, it's big enough to drive a truck through. this chemical and many other ones we don't know a lot about in terms of human health risks. >> there's a proposal from senators manchin, rockefeller, and boxer to introduce some kind of reform legislation in the wake of this spill. those are some of the main items, establish a state inspection programs for chemical facilities, sets minimum inspection requirements and standards for facilities, directs states to identify at-risk facilities. my question is, are we seeing a gap in the law here, or are we seeing a gap in the enforcement of the law? and would this new piece of legislation fix it? >> well, the bad news is, we're seeing both. so, this legislation, if it passes, would also, honestly, chris, require another bill updating this tosca bill from 1976, in order to have stronger testing standards. so, you know, what we're talking about here in west virginia, from senator manchin, is better regulation of above-ground chemical storage. right now, the rules only apply to underground chemical storage. that's step one.
