Much has been made about the Bush administration’s 11th hour repeal of a key rule meant to keep coal-slurry waste out of Appalachian streams — a repeal that went into effect this month. But check out what’s happening in northern Appalachia — the capital of longwall coal mining, a little-known but devastating extraction method that collapses the ground beneath homes. The mining industry is quietly pushing to downgrade “high quality” streams in a move that’s giving environmentalists there nightmares.

As environmental groups in West Virginia, Kentucky, and Washington, D.C. work to reverse the January 12 repeal of the so-called “stream buffer zone” rule — a tough restriction against mountaintop removal mining — Pennsylvania advocates are organizing to halt what they say is the longwall industry’s more subtle loosening of stream protections. In the southwestern corner of Pennsylvania, two companies — Consol Energy and Foundation Coal Holdings — are trying to change the stream classification known as “high quality warm water fishes” on tributaries running close to their longwall mines. The companies have petitioned the state’s environmental court to downgrade four streams to the less protective label of “warm water fishes.” That means the companies wouldn’t have to abide by the most stringent pollution controls and water-quality standards designated for tributaries supporting sensitive fish and insects.

Activists see the push as a worrisome precedent that would allow not just the coal industry, but any industry to reclassify streams in order to pollute them, which obviously undermines the purpose of the classification system.
