Top federal regulators have recommended informally that the White House relax one of the nation's most contentious air pollution regulations, a provision that requires power plants to upgrade pollution control equipment when they upgrade their operations. Such a move has long been pushed by energy and industry groups -- many of whom have been big supporters of President Bush -- who say that current rules impose billions of dollars in extra costs that unfairly block utilities from modernizing to make plants more energy efficient. Environmental groups have been equally vehement in their support of the current regulations, saying that any relaxation would amount to the biggest rollback of the Clean Air Act since its passage 30 years ago. In addition, the attorneys general from some states in the Northeast, which often bear the brunt of pollution from industrial plants in the Midwest, plan to gather here on Tuesday to protest any changes in the regulations. While no final recommendations have been formally sent to the White House, officials said that the tentative results of discussions between the Energy Department and the Environmental Protection Agency had been given to the Council on Environmental Quality at the White House. "We have submitted a suggested set of reforms," one official said. "We're pretty far along." http://www.nytimes.com/2002/01/08/politics/08AIR.html - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - For SC email list T-and-C, send: GET TERMS-AND-CONDITIONS.CURRENT to [log in to unmask]
