Every year, the Environmental Protection Agency comes out with
the Toxic Release Inventory (TRI). And every year the mining
industry comes out on top—or bottom, depending on your
perspective. The year 2008 was no different.
The top five facilities in the nation with the most releases were
mining operations, and two of them were in Nevada. Nevada ranks sixth
in the nation for reported toxic releases, and it ranks No. 1 in
mercury releases. Nevada mines accounted for 99 percent of the mercury
released in the EPA’s Region 9, which also includes California,
Arizona and Hawaii.
However, toxic releases in Nevada were down 10 percent from 2007,
mostly because of fewer gold mining releases. There was a downward
trend nationwide, where releases decreased 6 percent. This was partly
due to fewer facilities reporting, which, the EPA said, could be the
economy’s doing.
The top 10 Nevada facilities with the most chemical releases in
2008:
1) Newmont Mining Copper Canyon Facility in Battle Mountain released
52.9 million pounds of toxic chemicals.
2) Barrick Goldstrike Mines in Elko: 48.8 million pounds.
3) Newmont Mining’s Twin Creeks Mine in Golconda: 32.2 million
pounds.
4) Newmont Mining’s Carlin South Area in Carlin: 26.8 million
pounds.
5) Robinson Nevada Mining in Ruth: 14.1 million pounds.
6) Cortez Gold Mines in Crescent Valley: 11.09 million pounds.
7) U.S. Ecology Nevada , a radioactive and hazardous waste disposal
company in Beatty: 3.19 million pounds.
8) Smoky Valley Common Operation , a gold and silver mine in Round
Mountain: 1.78 million pounds.
9) Newmont Mining’s Carlin North Area in Carlin: 1.4 million
pounds.
10) Newmont Midas Operations in Midas: 1.2 million pounds.
Nevada’s top four polluters also ranked among the
nation’s top 10: Newmont’s Copper Canyon was No. 3; Barrick
was No. 4; Newmont’s Twin Creeks was No. 7; and Newmont’s
Carlin South Area was No. 10.
While the TRI is helpful from a public-right-to-know standpoint,
there are some things to consider. For instance, it doesn’t note
the time of release. “If you have a company that shuts down
during winter … and opens when there are no inversions and high
winds, that’s less of an impact to the citizens of this area than
24-hour, around-the-clock emissions,” says John Sagebiel,
environmental affairs manager at the University of Nevada, Reno
Furthermore, the TRI tends to treat chemicals equally, listing them
by pound, though some chemicals are worse than others. For instance,
toluene, though toxic, eventually breaks down, whereas mercury
doesn’t go away. Yet a facility emitting more pounds of toluene
than one emitting mercury would be ranked higher on the list of
emitters.
Also not considered in the TRI is data from you and me, or rather,
anyone who drives a vehicle. It doesn’t include information on
vehicle emissions, which release a significant amount of toluene,
xylene and formaldehyde to the air. Though that adds up collectively,
“We’re not individual big emitters,” says Sagebiel.
“TRI is for big emitters.”
