"In its new report, the National Parks Conservation Association identifies the top 10 national parks at risk from pollution from new coal-fired power plants. Already, NPCA has identified that one in three national park sites has air pollution levels that exceed health standards set by the U.S. Environmental Protection Agency. Yet, the Administration is responding to this growing threat to our national parks by seeking to weaken and rewrite the very laws that protect national park air quality. Over the objections of its own scientists, and those at the National Park Service, the EPA has proposed regulatory changes that will make it easier to build new coal-fired power plants near national parks."
