Finally, a Victory Against Mountaintop Removal
The first crack in a firewall that has protected big coal for decades.

Since the 1990s, small bands of Appalachian residents, regional environmental groups, and more recently the EPA have fought what often seemed like a futile battle against mountaintop-removal mining, the radical practice of blowing the tops off mountains to get at the coal seams underneath. The coal companies, backed by local political establishments and conservative jurists skeptical of possible regulatory overreach, have fended off multiple attempts to shut down mountaintop operations. As a result, an ever-widening swath of Appalachian peaks and valleys has been obliterated: approximately 2,200 square miles, according to the EPA, in what is likely a conservative estimate because the footprint often extends beyond the permit zones. That’s an area almost the size of Delaware.
That expanse kept growing as the battles mostly went in coal’s favor. Until this month, that is, when environmental groups won a decisive legal victory over a coal company. It may prove to be turning point in the war over the mountaintops, and for the future of coal.
On Nov. 15, St. Louis-based Patriot Coal agreed to phase out its mountaintop excavations and redirect its efforts back to underground mining. Adding a symbolic punch, Patriot agreed to decommission its two draglines—enormous boom excavators that do the actual mountaintop demolitions—and can sell them only on the condition that they’re never used in the Appalachian coalfields again. Coal executives usually shrug off complaints about mountaintop-removal impacts as the grumbling of dilettantes and naysayers who don’t understand the need for mining jobs. Yet here was the practically unheard-of spectacle of Patriot’s CEO, Ben Hatfield, acknowledging that mountaintop removal affected both people and ecology: “Patriot Coal recognizes that our mining operations impact the communities in which we operate in significant ways, and we are committed to maximizing the benefits of this agreement for our stakeholders, including our employees and neighbors," Hatfield said in court. "We believe the proposed settlement will result in a reduction of our environmental footprint."
True, a specific chain of misfortunes brought Patriot to the table. It’s looking to exit from bankruptcy, the result of falling coal prices, bad business decisions, and huge pension obligations. It was in this context that Appalachian environmental groups forced their issue. Patriot was also on the hook for hundreds of millions of dollars to clean up discharges of the mining pollutant selenium from its operations. Pulling the plug on mountaintop removal was part of the cleanup settlement. Other companies aren’t planning to follow suit: “No, the decision and agreement is theirs and it does not affect our mining plans,” a spokesman for Alpha Natural Resources, the leading surface mining company in West Virginia, told the Charleston Gazette.
But Patriot’s woes aren’t unique. They grew out of endemic problems with mountaintop removal that have been getting worse, putting mounting legal, regulatory and economic pressure on the companies that do it.
Appalachian forests are an ancient and unique ecosystem, one of the oldest in the world, with some of the highest levels of biodiversity to be found in a temperate zone. Destroying them is almost by definition ecological disaster. But because mountaintop removal in Appalachia is a relatively new phenomenon, it’s only in the past few years that scientists have begun to fully document not just the extent, but the nature of the damage.
Mountaintop removal is a three-step process. In the first, peaks are dismantled, descending layer by layer, using explosives and draglines, and the coal harvested. I’ve been to Patriot’s Hobet mine in Boone County, W.Va. Its sprawling operation—the largest single mountaintop-removal mine, covering more than 25 square miles—evokes the smoky, cratered, lifeless aftermath of a World War I battlefield. In the second phase, the vast piles of rock and soil debris this creates—larger in volume than mountaintops themselves, because of the extra space between all those boulders—are dumped in neighboring valleys, creating so-called “valley fills.” Finally, the lopped-off mountaintop is usually bulldozed and planted with something green, creating artificial meadows where none existed before.
The worst problem isn’t actually the missing peaks. Forests can be replanted, and sometimes the more virtuous companies actually do this. It’s what the mines do to the delicate mountain waterways. Dumping a mountaintop’s worth of rock into a valley doesn’t just obliterate all life there. It stops up headwater streams, literally the wellspring for the forest ecosystem and the point of origin for entire watersheds. So far more than 1,200 miles of stream beds have been buried. These cannot be restored. And rainwater that once would have fed those nascent brooks passes through a filter of mashed-up mountain instead.
“There are coal residues mixed with shale rock that’s been buried for millennia, trace metals, pyrite, all these salts weathering out of the rock. Then it’s sitting right in the stream network,” says Emily Bernhardt, a Duke University biologist who has been studying the impacts of mining. “As it rains, it’s basically a chemical battery, if you will, that is constantly releasing its contents into that stream network.”
This “battery effect” generates a range of problems for miles downstream. It injects high levels of mineral ions into the water, where high electrical conductivity harms many kinds of aquatic life. Hard-hit species include mayflies, which happen to sit at the bottom of the forest food chain and are a broad indicator of ecosystem health. An EPA study that first drew wide attention to this problem in 2008 said: “Our results indicate that [mountaintop mining] is strongly related to downstream biological impairment.”
