The Environmental Protection Agency announced October 21 that it will postpone until December 16 its planned mercury and toxics air standards for coal and oil-fired electric steam generating units, but that it opposes efforts by utilities to delay the rule for one year. The agency filed a brief with the U.S. District Court for the District of Columbia last Friday, in which, with agreement from environmental litigants, it delays its final issuance date of the utility MACT rules one month in order to respond to comments, and in another brief filed with the same court, the agency opposed utilities’ petition to delay the rule.
