In an about-face, the Environmental Protection Agency (news - web sites) on Thursday acknowledged that it will apply less stringent pollution standards to cases brought against some utilities for Clean Air Act violations.
Word of the change trickled out on Wednesday, the day before former Utah Gov. Mike Leavitt took office as EPA administrator. Leavitt replaced Christine Todd Whitman (news - web sites), who was often at odds with the administration's environmental agenda.
Democrats called for a probe of the EPA's failure to enforce the previous, stricter rules. They also said the new rules could endanger ongoing cases, where utilities face billions of dollars in dirty air fines.
