The Utility Air Regulatory Group and 25 states petitioned the U.S. District Court for the District of Columbia October 7 to postpone until 2012 the deadline for the Environmental Protection Agency to issue a final rule requiring power plants to control toxic emissions. The agency currently has a November 16 deadline to issue the rule, which will establish maximum achievable control technology standards for power plants, as part of a consent decree with public health and environmental groups.
