Enviros Fight Gold Miners' Vacuum Dredging
Document Actions
PORTLAND, Ore. (CN) - Environmentalists say Oregon is letting
gold miners abuse the environment by using suction dredging of
riverbeds to further degrade waters that are already in bad shape.
Miners use giant hoses to suck up stream beds in their search for
gold. The Northwest Environmental Defense Center says a permit issued
by the Oregon Department of Environmental Quality violates the Clean
Water Act.
The new suction dredging permit allows miners to use hoses 4 to 6
inches in diameter, with 16 to 30 horsepower engines, to vacuum up the
bottoms of streams.
Suction dredging increases sedimentation and turbidity and
reconfigures the riverbed, destroying fish habitat and raising a
stream's temperature, according to the complaint, which includes the
Klamath-Siskiyou Wildlands Center as co-plaintiff.
The groups say that suction mining destroys gravel beds that
fish, including salmon, use as spawning grounds.
The plaintiffs say they have documented the environmental harm of
suction dredging at sites around the state. They say the damage is
exacerbated because some miners, in online posts, assert that they do
not have to comply with permits.
The 2010 permit does not require Oregon streambed miners to
adequately report on or monitor their activities in waters that are
already impaired, in violation of the Clean Water Act, according to
the complaint.
Represented by the Pacific Environmental Advocacy Center, the
groups want the court to set aside the 2010 permit.
The plaintiffs also challenged permits issued in 1997 and 2005.
The first challenge resulted in a court order telling the state's
environmental department to incorporate nondegradation policies under
the Clean Water Act.
For the second challenge, at the appellate level, the Eastern
Oregon Mining Association's involvement resulted in a ruling that the
state environmental department has no permitting authority for suction
dredging, as the U.S. Army Corp of Engineers retains jurisdiction
under the Clean Water Act.
This second challenge made it to the Oregon Supreme Court before being
mooted in light of the environmental department's issuance of the new
permit.
