EPA Moves to Ease Air Rules for Parks

The Environmental Protection Agency is finalizing new air-quality rules that would make it easier to build coal-fired power plants, oil refineries and other major polluters near national parks and wilderness areas, even though half of the EPA's 10 regional administrators formally dissented from the decision and four others criticized the move in writing. The proposal would change the practice of measuring pollution levels near national parks, which is currently done over three-hour and 24-hour increments to capture emission spikes during periods of peak energy demand; instead, the levels would be averaged over a year. Under this system, spikes in pollution would no longer violate the law. Many national parks struggle with poor visibility shrouding otherwise spectacular vistas, as well as acid rain and other problems caused by air pollution.
