MINING IMPACTS:

Mining’s public face is that the industry provides good jobs and vital resources to run our modern economy.   Rarely seen and never promoted are the results of our addiction to mining and extraction.  The massive scars and grotesque tailings mountains are seldom photographed or portrayed.  Higher rates of asthma, heart disease and cancer are inflicted upon local residents.  The industry won't boast that many mining jobs have dried up, due to automation and increased surface mining.  Or that company profits mostly leave the local economies. 

These are among the issues many mining and fracking communities face, across our nation.  Do extractive operations bring a net economic benefit or a detriment to local communities?  This is a legitimate and relevant question.  What can we do?  We can work to get money out of politics.  We can push for more public input, for better regulations and for their enforcement.  And we can push for the phase-out of fossil fuels, to be replaced by clean renewable energy.

 'Berkeley Pit: Legacy," 2012

Berkeley Pit, Butte, Montana

The Berkeley Pit is a former open pit copper mine located in Butte, Montana.  It is one mile long by a half mile wide and almost 1800 feet deep.  At one point, it was the largest copper pit in the nation.  Prior its opening in 1955, many underground mines were active, but open-pit mining became far more economical and safer.  Two communities and much of Butte's east side were consumed by the pit's expansion, which came to within four blocks of Butte's center.  The homes were either destroyed or moved to the southern end of town.  Residents were compensated for their lost property.

When pit operations were ceased in 1982, water pumps in a nearby shaft were shut off.  Groundwater began filling the pit, one foot per month.  The highly acidic water is laden with dissolved metals such as copper, aluminum, cadmium, cobalt, iron and zinc.  At times, a metallic fog drifts into town.  This lake has risen to within 150 feet of the groundwater table, estimated to occur by 2020.  If allowed to happen, it would pose a serious environmental problem, as the toxic water would flow back into the surrounding groundwater.  Water flowing into the pit is now diverted to slow the rising level.   A water treatment plant opened in 2004; it treats and diverts incoming water.  Later it will treat existing pit water as the critical level approaches.  The Berkeley Pit is part of the largest complex of Superfund sites in the US.

If birds get trapped in the pit by fog and storms, they will perish by internal corrosion.  This happened in late 1995 when 342 geese died, and in late 2007 when 37 waterfowl died.  To prevent bird fatalities, an observation station now overlooks the pit, equipped with scopes and spotlights.  Personnel observe throughout the day, and use sounding devices and guns to scare the birds away.  A boat tours the lake to search for dead birds – many birds do perish and many are resuscitated.

 "Civilization," 2012

Kennecott Utah Copper Mine, Salt Lake County, Utah

The Kennecott mine (also known as the Bingham Mine) is currently the second-largest copper producer in the US, providing nearly a quarter of the nation's copper.  It is the oldest open pit copper mine; during World War II, it provided about 30% of the copper used by the Allies.  It also yields gold, silver and molybdenum.  This is one of the largest human-made excavations on Earth, measuring 2 3/4 miles across and 3/4 mile deep, visible from space.  As the mine expanded, it consumed the town of Bingham, which ceased to exist in 1971.  The mine changed hands several times over the years, and is now owned by Rio Tinto, the third largest mining corporation in the world.

Kennecott is also the largest mine near an urban area in the world – the Salt Lake City metro area – so one million nearby residents are affected by the mine's impacts.  Approximately 80 square miles of groundwater is contaminated in the southwest portion of the valley – the world's largest toxic plume.  Significant remediation efforts are underway.  The mine is responsible for about one-third of the air pollution in Salt Lake County.  Salt Lake City consistently ranks in the top ten for bad air quality.  The effect on residents' health is substantial, with high rates of asthma and 1000-2000 premature deaths each year, according to Dr. Moench, the president of Utah Physicians for a Healthy Environment.  The mine and its smelter also release a large source of heavy metal contamination to the area; the smelter alone releases over 6000 pounds of lead emissions per year.

In spite of this heavy impact, Rio Tinto is seeking to expand the mine's rate of extraction by nearly a third, gaining approval from the Utah Division of Air Quality Board – even while Salt Lake County is out of compliance with EPA standards for PM10, PM2.5 and ozone.  The airshed and valley residents cannot afford this expansion.  Thus, Utah Physicians for a Healthy Environment is joined by the Utah Chapter of the Sierra Club, Utah Moms for Clean Air and WildEarth Guardians in a lawsuit to stop the expansion.

 "El Chino," 2012

El Chino (Santa Rita Mine), Southwest New Mexico

The Chino Mine (Spanish for "Chinaman"), is an open pit copper mine located near Santa Rita, New Mexico.  This huge mine was once the largest in the world, and has been perhaps the oldest operational mine in the American southwest.  It is the third oldest open pit copper mine in the world, Kennecott being the oldest. 

The town of Santa Rita was forced to move several times for the pit's expansion.  Shortly after the town moved in 1957, heavy rains washed boulders and mud into the new town-site.  The town was abandoned once and for all in 1967, remaining only on the pages of history books.

Mountaintop Removal, Eastern US

Mountaintop removal mining (MTR) is a form of surface mining that takes place on the summit or summit ridges of mountains.  This is becoming the dominant method of coal mining in the southern Appalachian Mountains, especially in West Virginia and Kentucky.  This region is one of the richest ecosystems in North America.  

 "Green Coal," 2012

MTR is one of the most destructive methods for extracting fossil fuels.  So far, 500 summits have been leveled, wrecking an area of land the size of Delaware.  The overburden, removed to access coal seams, is dumped into streambeds, which pollutes waters downstream.  Operations detonate 2,500 tons of explosives per day in the region, the equivalent of a Hiroshima bomb every week.  The blasts damage nearby homes and cover communities with toxic coal dust, burdening local residents with high rates of cancer and heart disease.  Massive amounts of coal slurry (from processing) are held in hundreds of impoundment ponds throughout the region.  Coal companies are supposed to reclaim the land, but all too often the land is left stripped.  Even with remediation, the land never returns to its formerly healthy condition. 

Rather than a boon, MTR is detrimental to the region's economy and to the well being of the people.  In West Virginia, surface mining accounts for only 1.2 percent of the jobs (many are hired from out of state).  Automation has cut most mining jobs.   The impacted counties are among the poorest in the nation, with high cancer, mortality rates and health care costs.

 "Black Thunder," 2012

Black Thunder Coal Mine, Powder River Basin, Wyoming

Wyoming's Powder River Basin contains one of the largest coal deposits in the world.  Black Thunder Mine is one of the largest mines in the world, now supplying 8 percent of US coal supply.  This mine cranks out enough coal to load 25 miles of train cars per day.  These coal trains fan out across the nation, even to the East Coast.  As production has dwindled in mines across the US, this region now provides over 40 percent of the nation's coal. 

The combustion of Powder River Basin coal is responsible for almost 13 percent of the total US emissions of CO2 – the primary greenhouse gas that is quickly accumulating in our atmosphere.  The buildup of greenhouse gases will cook us all if we do not phase out coal and other fossil fuels as soon as possible.

Castle Mountain Gold Mine, Southern California 

The now-closed Castle Mountain mine is located next to the Mojave National Preserve, near the Nevada border.  The mine wasa operational from 1992-2003.  It was not a successful venture and lost money, since the price of gold was down, even though it was California's third largest gold mine at the time. 

 "Castle Mountain," 2012

It has become the norm for gold operators to dig huge open pits and to discard piles of waste rock – then to pour toxic cyanide over crushed ore rock to leach out the gold.  When the depleted mines are abandoned, the steep-walled open pits often fill with polluted water.  

In 2003, California enacted the nation's toughest regulations on open-pit metallic mining, requiring that upon termination of operations, the affected lands be "reclaimed to a usable condition which is readily adaptable for alternative uses and create no danger to public health or safety."  This requires backfilling open-pit metal mines, and that companies provide financial guarantees so taxpayers wouldn't be stuck if the company defaults.  

At the Castle Mountain site, two pits will remain.  The law also mandates that the mining company work to restore the land by removing industrial facilities and planting native vegetation – in this case, Joshua trees and cactus.  There will be further restoration, if the Park Service has its way.
