Yesterday was a great day for the people of Appalachia and for all of America. In a bold departure from Bush-era energy policy, the Obama administration suspended a coal company's permit to dump debris from its proposed mountaintop mining operation into a West Virginia valley and stream. In addition, the administration promised to carefully review upward of 200 such permits awaiting approval by the U.S. Army Corps of Engineers. Mountaintop-removal coal mining is the greatest environmental tragedy ever to befall our nation. This radical form of strip mining has already flattened the tops of 500 mountains, buried 2,000 miles of streams, devastated our country's oldest and most diverse temperate forests, and blighted landscapes famous for their history and beauty. Using giant earthmovers and millions of tons of explosives, coal moguls have eviscerated communities, destroyed homes, and uprooted and sickened families with coal and rock dust, and with blasting, flooding and poisoned water, all while providing far fewer jobs than does traditional underground mining. The Corps has been working overtime to oblige impatient coal barons by quickly issuing the pending permits. Each such permit amounts to a death sentence for streams, mountains and communities. Taken together, these pending permits threatened to lay waste to nearly 60,000 acres of mountain landscape, destroy 400 valleys and bury more than 200 miles of streams. The Corps already had issued a dozen permits before the White House stepped in.
