Scientists, managers oppose plan that may allow for new power plants

The Bush administration is on the verge of implementing new air quality rules that will make it easier to build power plants near national parks and wilderness areas, according to rank-and-file agency scientists and park managers who oppose the plan.

The new regulations, which are likely to be finalized this summer, rewrite a provision of the Clean Air Act that applies to "Class 1 areas," federal lands that currently have the highest level of protection under the law. Opponents predict the changes will worsen visibility at many of the nation's most prized tourist destinations, including Virginia's Shenandoah, Colorado's Mesa Verde and North Dakota's Theodore Roosevelt national parks.

Nearly a year ago, with little fanfare, the Environmental Protection Agency proposed changing the way the government measures air pollution near Class 1 areas on the grounds that the nation needed a more uniform way of regulating emissions near protected areas. The agency closed the comment period in April and has indicated it is not making significant changes to the draft rule, despite objections by EPA staff members.

Jeffrey R. Holmstead, who now heads the environmental strategies group at the law firm Bracewelll & Giuliani, helped initiate the rule change while heading the EPA's air and radiation office. He said agency officials became concerned that the EPA's scientific staff was taking "the most conservative approach" in predicting how much pollution new power plants would produce.
