Mountains really can be moved. Or removed
, at least. In one type of surface mining, entire mountaintops are razed to extract coal, and the byproducts are dumped into nearby water sources.
Can a mountain be removed explain the process?
Mountaintop removal is
any method of surface coal mining that destroys a mountaintop or ridgeline
, whether or not the mined area will be returned to what is legally described as the “approximate original contour.” Methods of mountaintop removal coal mining include, but are not limited to: cross-ridge mining, box-cut …
Does mountaintop removal still happen?
Despite an ongoing citizen movement to end the destruction, and despite the decline in coal,
it’s still happening
. … The massive amounts of dirt and rubble, what the coal industry calls “overburden,” is dumped into adjacent valleys, burying headwater streams.
Is mountaintop mining illegal?
Mountaintop removal mining is an extremely destructive form of mining that has already permanently buried more than 1,200 miles of streams in West Virginia and other states. … The U.S. District Court for the Southern District of West Virginia today found those permits violate the Clean Water
Act
.
How is mountaintop removal legal?
Disposal of excess overburden associated with mountaintop removal mining has generally been
permitted under Nationwide Permit 21
(NWP 21), which authorizes discharges from surface coal mining activities that result in no more than minimal impacts (site-specifically and cumulatively) to the aquatic environment.
How many mountains have been destroyed by mountaintop removal?
Tragically, mountaintop removal mining has already destroyed
more than 500 mountains
encompassing more than 1 million acres of Central and Southern Appalachia.
Why is restoration hard after mountaintop removal?
Why might restoration be hard after mountaintop removal?
mountains form over long periods of time and therefore can’t be replaced in short amounts of time
.
Has a mountain ever been removed?
More than 500 mountains in the US
have been destroyed by this process, resulting in the burial of 3,200 km (2,000 mi) of streams. Mountaintop removal has been practiced since the 1960s.
How does Mountain Top Removal Work?
“Mountaintop removal/valley fill is a mining practice where
the tops of mountains are removed, exposing the seams of coal
. Mountaintop removal can involve removing 500 feet or more of the summit to get at buried seams of coal. The earth from the mountaintop is then dumped in the neighboring valleys.”
What are negative effects of mountaintop removal?
Toxic heavy metals such as cadmium, selenium, and arsenic leach
into local water supplies, poisoning drinking water. This destructive practice, known as mountaintop-removal mining, sends carcinogenic toxins like silica into the air, affecting communities for miles around.
What animals are affected by mountaintop removal?
Recent scientific studies have concluded that pollution from mountaintop-removal coal mining is harmful to
fish, crayfish, mussels, amphibians and stream insects
in Appalachia. Pollution from mountaintop removal is also associated with increased risk of cancer and birth defects in humans.
Contaminants from mountaintop removal even poison the
drinking water
of downstream communities. And this form of mining makes a twofold contribution to climate change: The forests destroyed in the process no longer store carbon, and the burning of the coal that’s mined releases carbon into the atmosphere.
What causes mountaintop removal?
Michael Hendryx: Mountaintop removal is a form of
surface coal mining
. As the name suggests, it literally removes up to 800 feet off the tops of mountains to try to reach coal seams that are not accessible by other mining techniques because the terrain is too steep or the veins are too thin.
Which type of mining is likely the least harmful to the environment?
Placer mining
can be less damaging to the environment than surface mines, as the sediment is returned to the water after the minerals have been extracted.
How does mountaintop removal affect humans?
Since 2007, peer-reviewed studies by researchers from more than a dozen universities have concluded that mountaintop removal coal mining contributes to
significantly higher rates of birth defects, cancer, cardiovascular and respiratory diseases
among individuals living in the region where it occurs.
How does mountaintop removal affect the Appalachian Mountains?
The impacts on communities of blowing up mountains and dumping the rubble into streams are profound. It forces residents to contend with
contaminated drinking water
, increased flooding, dangerous coal slurry impoundments, and higher rates of cancer and other health issues.
