Too early to say what we think is going to happen in the individual states that we operate in. We're very actively participating in the process, whether with EEI or whether it's in Colorado, South Dakota or Wyoming with the various state agencies. You really need to get all the players in each state together to really discuss the issues and concerns there. Frankly, in South Dakota, we don't have any coal-fired generation in South Dakota anymore, so we really have very little issue in South Dakota based on what we see today. Still assessing the situation, but we just don't have any baseload fossil-fired units in South Dakota, so should be kind of a nonevent there. Wyoming, we've got one of the most modern fleets in the country, frankly, coal fleets. All 4 units there are 1996 vintage or newer, all extremely low emissions for everything but CO2. If we have to reduce CO2 emissions at those plants, we believe we can do that through relatively economic means, whether that's coal-firing a portion of natural gas or something. We're investigating all of those alternatives. It certainly would have a rate impact on customers, but we really don't know what we would need to do, if anything, until we know what the other players in the state are going to do. And primarily those are based in electric, the coop and PacifiCorp. And we're still working our way through that process in the state, meeting with the state Public Service Commission, the State Department of Environmental Quality and any other players, so a little too early to tell what's going to happen there. Colorado, very similar circumstance. We really don't have any coal units there anymore either, we don't. We retired our W.N. Clark in Cañon City. We've got a couple of combined-cycle gas units there. But beyond that, frankly, there's not a whole lot we will need to do or be expected to do. Again, you're looking at a discussion with the state. The other players in the state, notably, Tri-State on the coop side and of course, excel on the investor-owned side, so a little early. But I think from a relative perspective, compared to most of our industry peers, I think we're in very, very good shape. That being said, I think the rules are extremely onerous, and if it goes through, it's going to have a real dramatic negative impact on customers. Ours is less so than most of our peers, but it's a very, very complicated and very, very expensive rule, if it gets completed as proposed.
