A legal war between the states erupted Wednesday over the federal government's move to relax air pollution regulations.
Nine states are taking on 14 states that want to block new federal rules relaxing pollution requirements for power plants, refineries and manufacturers. The battle falls along partisan lines.
Virginia's attorney general, Jerry Kilgore, a Republican, led his state and Alabama, Alaska, Arkansas, Kansas, Nebraska, North Dakota, South Dakota and Utah in asking to intervene in a case filed in the U.S. Court of Appeals for the District of Columbia.
Fourteen states last week filed suit to stop the Environmental Protection Agency from implementing new Clean Air Act rules that make it easier for older plants to make upgrades without having to install more pollution controls.
The nine states argued in court papers filed Wednesday that the lawsuits "will have a negative effect on them" by increasing the cost of enforcing air pollution cases, limiting enforcement options and "frustrating" industry's ability to make efficiency and cost-saving improvements.
"The changes at issue in this case will have a substantial impact on both the states' costs of enforcing the act's requirements and the flexibility that the states enjoy in enforcing those requirements," Kilgore wrote on behalf of the attorneys general.
All but two of the attorneys general representing the 14 states are Democrats; Peter Heed of New Hampshire and Mike Fisher of Pennsylvania are Republicans.
Filing suit against the EPA to block the new rules from going into effect Dec. 26 were New York, California, Connecticut, Illinois, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New Mexico, Pennsylvania, Rhode Island, Vermont and Wisconsin.
The states were joined by a number of cities, including New York, San Francisco, and Washington.
Scott Segal, director of the Electric Reliability Coordinating Council, a group of power companies, called the nine states' challenge "a principled stand that echoes the sentiment of many other organizations and state officials."
The new rules have been one of the most controversial actions of the Bush administration, angering many environmentalists. New York Atty. Gen. Eliot Spitzer said that if the EPA's new rules go into effect even temporarily, pollution will increase and decades of Clean Air Act protections will cease.
