Yes, the states need to come up with their plans, and there isn’t really any state that’s going to go down the path of saying, here’s the rate performance that a unit has to do. You’re going to have to utilize, whether it’s the renewables or energy efficiency of whatever the case may be, to work down towards that average, and if you look at our fleet outside of Illinois and Ohio, the emissions rates of our fleet versus the targets that those states have to get to, we’re essentially a net--we generate less emissions than what their rates are, so you are a beneficiary or providing beneficial services to that particular state in terms of bringing the average down. In Illinois and Ohio where we have the coal plants, we’re above the targeted rates to get to, so for there it’s going to be working with state agencies, state implementation plans on kind of all of the above to get the blended rate to that level. Or, what a state may do is rather than thinking about rates but go to the mass requirement, which is probably the more likely circumstance, which then it’s a situation of using credits to help bring it down. In a market like Illinois, where you have so much coal generation, and particularly coal generation that’s on the margin, if you get into a credit type of scheme, then it’s largely going to be a pass-through because it’s going to be coal setting the price. In Ohio, that might be a little bit different because you’ve got more gas resources there. So it really is going to come down to--you know, we wanted to include something on the clean power plan because it’s obviously in the news this week and has an impact on us going forward. So that’s just really some high level thoughts - our efforts need to be around Ohio and Illinois to make sure that the state implementation plan is a rational one that gets it to the point where the economics are right, and even--you know, I was at a session that Gina McCarthy was at, and she even said that by 2030, she still expects 30% of the generation in this country to be coming from coal. So working through programs like this, controlling on the mass level, our plants are positioned to be fine through that, and particularly since in Illinois you have coal-on-coal at times. It’s a pass-through if it’s based upon a credit.
