Major mountaintop removal story: The damage detailed

There’s a major story on mountaintop removal out today on Yale’s  Environment360 Web site. It was reported and written by three-time Pulitzer Prize winner John McQuaid, who has written before about the issue here and here.

In short, McQuaid concludes:

The environmental damage caused by mountaintop removal mining across Appalachia has been well documented. But scientists are now beginning to understand that the mining operations’ most lasting damage may be caused by the massive amounts of debris dumped into valley streams.

The story summarizes the state of the science, which was recounted previously on Coal Tattoo here, and reports:

… The scientific picture of mountaintop removal now emerging — from, among other things, the study of valley fills like the one in Laurel Branch — is, in its way, far more dramatic than any protest … The spread of mountaintop removal through central Appalachia in the past 15  years has given scientists the opportunity to study environmental destruction on a previously unthinkable scale: The Environmental Protection Agency (EPA) estimates that by 2013 a forested area the size of Delaware will have been destroyed and that more than 1,200 miles of streams have already been severely damaged. As that footprint has grown, so has the evidence, outlined in peer-reviewed scientific papers and ongoing investigations, showing that the damage is far more extensive than previously understood.

The Obama administration’s approach puts pressure on coal companies to compromise with regulators to limit some of the more egregious impacts of mountaintop removal. That may have some effect, but it will be limited by the government’s balkanized regulatory scheme for coal mining, which dates to the 1970s and never contemplated the vast damage that results when mountains are demolished.

The story offers little hope that the measures taken so far by the Obama administration will do much to stop the destruction:

In the case of valley fills, for example, only the EPA has ecosystem-wide responsibility through the Clean Water Act which governs what may be dumped in streams and waterways. But the agency’s power is circumscribed; it shares authority with the U.S. Army Corps of Engineers, which actually grants the dumping permits and has taken a much more sympathetic view of the practice. The Interior Department, meanwhile, oversees mountaintop projects via another law, the Surface Mining Control and Reclamation Act.

Nevertheless, the White House is betting that mountaintop mining can be managed and the damage ultimately repaired. But the science indicates that such an incremental approach may never be effective. Mountaintop removal does damage on both vast and microscopic scales, from hydrological changes over hundreds of square miles to effects on the life cycles of the tiniest stream microbes. Overseeing the repair of such damage is beyond the capabilities of any government agency; the most serious impacts — to streams — may be all but impossible to fix.

    My late friend Richard diPretoro, a Masters’-level hydrogeologist, used to say that the rubble left from surface mining (and also the “collapse zone” in an underground mine after the void caves in) were “zones of infinite permeability and porosity” or some such term — he would compare them to a sponge.
    He said that in these zones, the surface area of rock particles, that is available for various chemical reactions with the percolating groundwater, is increased by a HUGE factor over the situation in the original rock strata, where water mostly moves through fissures.
    Up North in WV and Western PA, this change in the earth’s texture and structure from mining has led in some geologies to immense quantities of incredibly toxic and acidic groundwater flow, due to iron and sulfur compounds associated with the sandstone that is exposed to groundwater in these rubble zones.
    I don’t know anything about the chemistry of the rock in Southern WV, other than that it’s not laden with iron/sulfur compounds like up North. But I think that the same principle — of exposing groundwater to thousands of times more mineral surfaces in the rubble that is left after mining — is in operation in all cases, North and South. Anyone have more to contribute?

    Yes, Todd, I think that is exactly true. Breaking up the rock increases natural weathering tremendously because exposed surface area has been so greatly increased. It occurs in all types of mines–not just coal–and in all types of rock, though the problem is more severe in certain rocks.

    Office of Surface Mining had a good page on acid mine draingage it that I can’t find right now, but the USGS has this page with a map of WV that you might find helpful:

    http://energy.er.usgs.gov/health_environment/acid_mine_drainage/

    These hydrological changes won’t just cause acid mine drainage, the will also change water flows & flood potential, favor different types of vegetation, and change the amount and way sediments are deposited. They will change a lot.

    It’s all part of the huge geologic-scale alterations man is making, if the Pleistocene was dominated by ice as the primary agent of geologic change, it’s our turn now. Some call it the Anthropocene.

    I read this story when Ken first posted it. I have thought about it a good bit. I find it interesting that finally science has come out and stated what the people who have lived here in the hills and hollows have know for many years. As a matter of fact we have been way out in front of those in science stating the adverse effects of MTR for a long, long time. It feels good to finally have people in positions that people will listen too come out and say how bad MTR is. It validates our battle against the atrocity that is being committed here.
