Cleaner Skies, But How?

The Environmental Protection Agency has decided to "issue a new rule that provides some certainty with a hard number. It's expected to rule that any plant upgrade whose costs exceed 20 percent of the cost of replacing all essential equipment would need to install pollution technology. In the regulatory world, a 20 percent threshold for enforcement is common, helping avoid a legal obligation to pay for "taking" of private property... At the same time, the EPA and the Bush administration are asking Congress to pass a bill called 'Clear Skies' that would lessen such an awkward regulation and create a market-based approach to meeting national air standards."
