mr. westmoreland. mr. westmoreland: thank you. going back to the cement issue, you know threarks a byproduct that comes from power plants, it's called fly ash. fly ash is a product that is a byproduct that comes out of the coal-burning plants and it's used in concrete and it keeps it from setting up so rapidly to allow the people to work with it, to get a good finish on it, takes it longer to set up. in the winter you can either put calcium in the concrete to make it dry harder or to at least make it dry if it's cold outside or you can leave the fly ash out of it and use a bag mix which makes the concrete more expensive. the e.p.a. came out with a rule or they're looking at a rule that would make this fly ash a toxin and so the cement industry, the concrete industry, went to them and said, look, we're mixing this stuff with concrete, once the concrete's poured, it's encased. i mean, you know, it's part of the mix. it's concrete. and so the e.p.a. said, yeah, that makes sense. it's not there but they still were still having hearing
