In the past 30 years, we have made dramatic strides with our centrally managed, highly prescriptive regulatory system -- a system that was innovative in its time, if only for the sheer scope of its reach. Yet we cannot regulate dry cleaners, printers, and auto body shops in the same way we regulated steel mills and chemical manufacturers. We must augment our law enforcement regime with a market-based, problem-solving approach -- an approach that has been tested successfully in the states. ...

While often overshadowed by their federal partner, the states are the primary actors implementing U.S. environmental laws today.

Clearly, it's up to Steve Johnson to explain why he fired Mary and up to Congress to investigate the circumstances.
