"Adding pressure on the Environmental Protection Agency to relax air pollution rules, 25 states urged a federal court on Monday to require the agency to delay a rule on mercury emissions and other pollutants from power plants by at least a year, saying the measure is too costly. "
... "The EPA is under court order to finalize the so-called maximum achievable control technology rule for utilities, also known as utility MACT, on November 16. But the states want the agency to delay the finalization of the rule, which is designed to reduce emissions of mercury and acid gases from power plants fired by coal and oil, until at least November 16 next year."
