From South Knox Bubba:

A federal appeals court has upheld some of Bush's changes to the EPA's "new source review" regulations that will allow industrial polluters, including power plants, to upgrade and expand their operations without updating existing pollution controls. Industry officials are elated.

In the same ruling, the court told the EPA to go back and work on a rule that allows polluters to not maintain records of their pollution if they think it doesn't exceed regulatory limits. In other words, polluters can continue regulating themselves, the EPA just needs to make sure the rule at least appears to pass the "snicker test."

Meanwhile, the Tennessee Valley and the Great Smoky Mountains National Park are on day two of an unhealthy ozone level and particulate matter alert.
