President Marking Earth Day

Bush marking Earth Day with visit to

Smokies President Bush is observing Earth Day today with a stop in the nation's most-visited -- and most polluted -- park.

The Great Smoky Mountains National Park, which straddles the North Carolina-Tennessee border, had nine million visitors last year. But smog and acid rain from coal-fired power plants put it well outside federal clean-air guidelines. Just this week, the administration and environmentalists agreed on a June deadline for new anti-pollution plans. They were supposed to have been issued today.

Bush will highlight his own Clear Skies initiative to curb power-plant emissions -- a plan environmental groups contend actually weakens current rules. But Bush also will pitch in on a trail restoration project. graphic
