10 States, in Challenge to U.S

ALBANY, May 1 â?? Ten states, including California and New York, plan to file suit this week to force the Bush administration to toughen mileage regulations for sport utility vehicles and other trucks.

The suit, which the states are to announce on Tuesday, contends that the administration did not do a rigorous enough analysis of the environmental benefits of fuel economy regulations, as required by law, before issuing new rules last month for S.U.V.'s, pickup trucks and minivans. The suit will also claim that the government did not consider the impact of gasoline consumption on climate change when devising the new rules.

While the states have initiated a number of suits over Washington's environmental policies, the new suit is the first to take aim at federal fuel economy regulations. With gasoline reaching $3 a gallon in many parts of the country, there has been a broad outcry for action but little consensus on what to do.
