California says it will fight any federal effort to restrict its ability to regulate vehicle emissions

As the Environmental Protection Agency signals its intent to roll back fuel standards for new vehicles, California officials are warning that any attempt to restrict its ability to set vehicle emissions standards will be met with fierce legal opposition:

Any decision to revoke California's federal waiver could spur a major legal fight, and the state has already retained former U.S. Atty. Gen. Eric H. Holder Jr. The state will "vigorously participate and defend ourselves" on setting the state's own air quality rules, California Air Resources Board Chair Mary Nichols said.

Automakers reportedly are pressuring the EPA to begin the process of limiting California's ability to set its own standards, which are widely adopted by other states, as well.
