“Significant effect on the environment means a substantial adverse change in the environment.”
California Environmental Quality Act Section 21068
I part ways with the environmentalists when their zeal for reform begins to resemble ecoterrorism, and where the rights and needs of humanity must take a backseat to nature.
THIS PRESENTATION IS An HONEST review of
scientific research results regarding the effects of
small-scale gold suction Dredging.
THESE DATA demonstrate that the process OF
SMALL-SCALE GOLD SUCTION dredging is NOT
harmful to man, fish, or the environment.

“Mining debris is chemically inert, makes no oxygen demand on the stream and therefore takes
away from the flowing water nothing which the fish require. This is equally true of this material
whether placed in transit by nature or by man since the products are alike in nature and comes from
the same sources…”
Turbidity was 656 NTU

Samples provided by Jim Foley and prepared by Claudia Wise
Research has found that duration of exposure plays a
more dominant role than TSS concentration
(Anderson et al. 1996).
For example, turbidity was 0.5 NTU upstream, 20.5 NTU 4 m downstream, and 3.4 NTU 49 m downstream of an
active dredge on Canyon Creek (Hassler et al. 1986).
On
Butte Creek and the North Fork of the American River where ambient turbidities were <1 NTU, maximum
turbidity 5 m downstream of active dredges reached 50 NTU but averaged only 5 NTU (Harvey 1986). One must
remember sediment plumes below suction dredges are intermittent not continuous.
Wanty et al. (1997) reported turbidity values of 19 NTU 30.5 m (100 ft) downstream of a 10 inch dredge located
below Wilson Creek on the North Fork Fortymile River. Values returned to near background levels (3.7 NTU) within the
next 30.5 m but remained slightly above background levels (2.2 - 2.3 NTU) as far as 150 m downstream
In Gold Creek, Montana, suspended sediment was 340 mg/L at the dredge outflow and 1.8 mg/L 31 m downstream of
an active dredge (Thomas 1985).

According to EPA and DEQ,
So do suction dredges.
Approximate size of a
4-inch Suction Dredge
By Tom Kitchar
The addition of a pollutant into a water system is key to whether or
not the EPA and the OR DEQ have regulatory jurisdiction over specific
mining activity.
Suction dredging within the normal high water mark of a river channel
does not add a pollutant to the water system. Because the miners and
prospectors are in the river channel, they can’t add anything that isn’t
already there.
U. S. Supreme Court Justice Sandra Day O’Connor’s majority opinion
rendered in the South Florida Water Management District v.
Miccosukee Tribe of Indians et al. tends to support the miner’s position
that turbidity is not a pollutant added to a waterway.
The Chief Justice likened a water system to a pot of soup. She
reasoned that, “If one takes a ladle of soup from a pot, lifts it above
the pot, and pours the soup back into the pot, one has not ‘added’
anything else to the pot.”
Impact WQ‐2: Effects of Contaminant Discharges of Oil or Gasoline Used in
Suction Dredges
(Less than Significant)
…the amount of fuel and oil spilled each year into surface water caused by
recreational dredging activities would be anticipated to be relatively small
based on the size of dredging motors, total number of dredges anticipated to
operate under the Program, and low probability that any individual dredger
would cause substantial fuel or oil spills while refueling.

2004 SALMON RIVER, CA STUDY
53 dredging sites were documented within
the Salmon River Basin.
1,066 linear feet of river bottom was dredged
within the entire river system.
The North Fork, South Fork and mainstem
Salmon River is approximately 79 miles long
(417,120 linear feet).
Suction dredge holes disturbed <0.26% of the
river bottom.

Salmon River Study Conclusions by Greene
Refugia are defined in the literature as any
hole in a river bottom that is 3 feet in depth
or deeper.
This study identified 27 such holes caused
by suction dredging.
Therefore, suction dredge holes disturbed
only <0.26% of the river bottom, and
51% of the 53 dredged holes had the
potential for improving the habitat to
support the survival of species in the river.

Sample Letter to Legislators
In his court declaration Dr. Peter Moyle stated, “It should be
assumed there is harm, unless it can be proven otherwise, One
reason for my taking this conservative position is that we
simply do not know the effects of dredging on many species”
(page 8, lines 13-15).
He goes on to say, “Even for salmonids, information on the
effects of dredging, with the exception of a few studies
such as that of Harvey (1998), is largely anecdotal or in non-peer
reviewed reports” (page 8, lines 20-23).

California, County of Alameda, Hayward Division, Case No: RG 05 211597. Jan. 06, 2006.

Effects of dredging commonly appear to be minor and local, but natural
resource professionals should expect effects to vary widely among stream
systems and reaches within systems.
… Given the current level of uncertainty about the effects of dredging,
where threatened or endangered aquatic species inhabit dredged areas,
fisheries managers would be prudent to suspect that dredging is
harmful to aquatic resources.

In 1,388 pages of text IN THE CALIFORNIA SUBSEQUENT ENVIRONMENTAL IMPACT REPORT
(SEIR) the term “Is Proven” is not once used. There are over forty years of suction dredging history yet the
SEIR must speculate on what “may” occur if gold dredging resumes.

CONCLUSION
Small-scale gold suction
dredging effects a very
small area in the
environment relative to
the entire area in which
all dredges operate.
But, what about government activity
and their effect on the environment???
Grand Canyon awash with Sediment as
Scientists Study Impact
The White Salmon River, WA at its confluence with the Columbia has filled with silt and is only inches deep since the breaching of
Condit Dam. The first 300 yards upstream from the Highway 14 bridge, once 18 to 20 feet deep and a popular trolling spot for
boating anglers, now has just a few inches of water running over a deep bed of sediment.
The sluice box filters out gold, platinum, lead, mercury, and many scrap metals from
the river’s gravels.
We recovered 65 lbs of lead, from the Lewis River, WA in just one fishing hole so far and we have not
finished with it. Yet.

IS IT ENVIRONMENTAL CONCERN THAT'S DRIVING
MINING OUT OF THE UNITED STATES OR RATHER
POLITICS ON THE GRANDEST SCALE?
The current administration has designated millions of acres of federal land off-limits to multiple uses such
as mining---and seems to be attempting to lock up public land --- all without consulting Congress or the
public.
The administration seems to be conforming U.S. environmental policy to United Nations Strategies.
The International Union for Conservation of Nature, an accredited scientific advisory body to the United
Nations, incorporates U.S. federal agencies, non-governmental organizations and United Nations agencies in
its proclaimed war against "ignorant humans."
Globalizing Mining in America, from Mining Voice Magazine Volume 6(2):26-35, March-April 2000
Critics of the administration’s land grab point to the
United Nations. They accuse the president of
implementing the UN’s Agenda 21 and the Convention
on Biological Diversity. Both were introduced during
the June 1992 Earth Summit held in Rio de Janeiro,
Brazil.
Agenda 21 is a 40-chapter, 381 page book focused on reorganizing society around
"sustainable" use and development of the planet. Based on socialist principles of equal
sharing of all natural resources. Agenda 21 sets a goal to control all human activity to
protect the Earth’s ecosystems and biological diversity.
Mining, for instance, would have to be "environmentally sound" and could only be done
"in areas adjacent to protected areas with a view to furthering protection of these areas."
The meaning of "protected areas" and "environmentally sound" is not defined in Agenda
21, but it is clarified in the UN Convention on Biological Diversity (Biodiversity Treaty)
and the Wildlands Project.
Dr. Reed Noss who is associated with the
Wildlands Project as well as the University of
Oregon and other radical environmental groups
describes a corridor that would be needed to
assure viability of the grizzly bear in Montana.
"If the population of grizzlies in the Greater Yellowstone Ecosystem is to be connected to other
populations, which seems to be necessary to assure population viability, then wide corridors with
resident grizzlies must connect Yellowstone with the Northern Continental Divide Ecosystem (about
200 miles away) and the wildlands of central Idaho. …corridor for grizzly bears should be at least
27.5 miles wide."
In further describing the corridor, he states, "Because Road densities above about 0.5 miles of road
per square mile of habitat may be a threat to grizzlies, road closures would be required to make
inter-regional corridors safe ."
TECHNICAL REVIEW OF THE WILDLANDS PROJECT AND HOW IT IS AFFECTING THE
MANAGEMENT OF STATE, FEDERAL AND PRIVATE LANDS IN THE UNITED STATES
by Tom McDonnell
This review details much of the structure and objectives of the Wildlands Project.
During the past several years, resource industries, state and local governments and
communities nationwide have been buried under an avalanche of: new species listings;
appeals and litigation to stop water development, logging, mining, grazing and
recreational activities. There have been vast amounts of legislation proposing new
wilderness areas, heritage areas, scenic rivers, biological corridors, state and national
parks or wildlife refuges, as well as management plans involving critical habitat,
watersheds or ecosystems.
http://citizenreviewonline.org/april_2002/wildlands_project_history.htm
While many of these actions seem to
be isolated incidence, a review of
Wildlands
Project
documents
suggests that the actions are often
well coordinated activities aimed
according to the Project's text at
establishing a "regional reserve
system which will ultimately tie the
North American continent into a
single Biodiversity Reserve."
http://citizenreviewonline.org/april_2002/wildlands_project_history.htm
…the mission articulated by White House Science and Technology czar, John Holdren, who said, “A
massive campaign must be launched to restore a high-quality environment in North America and to
de-develop the United States.”
Paul and Anne Ehrlich and John Holdren, Human Ecology Problems and Solutions (San Francisco: WH Freeman and Company, 1973), 279.
Significant additions to the timetable, was provided by President Barack Obama. Consider the
executive memorandum quietly issued by the White House on April 16, 2010, deceptively titled
“America’s Great Outdoors Initiative.” The stated goals of the Initiative: Reconnect… America’s
rivers, waterways, landscapes of national significance, ranches, farms and forests, great parks, and
coasts and beaches by… creating corridors and connectivity across these outdoor spaces, and
for enhancing neighborhood parks; and determine how the federal government can best advance
those priorities though public/ private partnerships and locally supported conservation strategies.
Barack Obama, “Presidential Memorandum— America’s Great Outdoors,” White House, April 16, 2010.
In presenting his unilateral order, Obama sealed the deal on what promoters of the green
agenda have desired for decades: “reconnect” the land of North America, creating several
sweeping “corridors” designed to provide seamless “connectivity” between millions of acres of
“outdoor spaces.”
Notice that “ranches, farms and forests” and “coasts and beaches” are also included in the
reconnection goals. This means that private ownership of such property is in the crosshairs of
this scheme. The Initiative will be advanced by “the federal government… working through
public/ private partnerships and locally supported conservation strategies.” This simple phrase
empowers environmental organizations and their deep-pocketed donors to have a seat at the
table with policymakers at all levels of government.

Sign Petition: This is why it is important!
Each year since 1986, American Rivers has released its
America's Most Endangered Rivers report to spotlight
the nation's ten most imperiled rivers. This year, the
Chetco River found itself at #7 on the Most Endangered
Rivers List. Southern Oregon's Wild and Scenic Chetco
River boasts pristine waters and abundant wild salmon
and steelhead, but it faces an immediate threat from a

Oregon's Senators Wyden and Merkley, Congressman
DeFazio, and Governor Kulongoski are calling on the
agencies that manage this river to prohibit mining in or
near the Chetco River this summer. This reprieve
would allow Congress time to legislate the best
possible long-term protection for the Chetco River.

The Chetco River, Oregon “faces an immediate threat from a strip mining
proposal that would use a highly damaging method of dredging.”
Why have a consortium of extreme environmental groups joined together
together to deny small-scale gold suction dredgers their right to mine?

The decision to change our name to
“Wildlands Network” has been both
exciting
and
difficult.
“Wildlands
Project” has been a cherished part of
our 18-year history. However, thanks to
you and our other partners and
supporters, we are no longer just a
project. We are an expanding network
of conservationists. You are part of this
network that is continuing to tackle the
continental challenge of protecting
healthy North American wildlands and
wildlife far into the future.

Social engineering and behavior modification are some of the true
objectives being implemented under the guise of environmental and
climate protection.
This is accomplished by exploiting people's desire to maintain a
healthy and lasting environment in the name of
“sustainability.”
the concept of sustainability is a call for government policies
that demand changes in human behavior and lifestyles under
penalty of law.
On its own, SUSTAINABILITY is one of those slogans that
sounds typically benign: But like most left-oriented
expressions, there is a sinister translation.
United nations Agenda 21 calls for worldwide population
reduction and suggests moving people from rural areas to the
cities, so “sustainable development” can be more easily
managed.
One of the United nations objectives is to reduce the world’s
human population by up to two-thirds of what is was in 1992.
Eco-Tyranny
“While
I was researching Climategate, I was
astonished by a recurring theme: since the
inception of the environmental movement, its
leaders have been consumed with eliminating
capitalism and ushering in a global era of
socialism.
Their call for being “green” goes far beyond
demanding clean air, pure water, healthy
forests, and alternative sources of energy.
The leftists at the helm of the
environmentalist hierarchy want to control
the air, water, forests, and natural resources.”
Brian Sussman, (2012). Eco-Tyranny: How the Left's Green Agenda will Dismantle America.
“These leftists contend that some people are randomly spit out of their
mother’s womb with a better brain than most. Those with the best
brains have a Darwinian authority to rule over those with the lesser
brains, lest those with the deficient brains destroy the planet and kill
one another; thus, the need for a heavy-handed form of government
loaded with burdensome regulations, and the perfect excuse for
socialism, communism, and fascism.”
Brian Sussman, (2012). Eco-Tyranny: How the Left's Green Agenda will Dismantle America.
“Leftists (Marxists) believe they have the power to define all societal morality,
rules, and laws subject to their goals. Hence, the inalienable rights of life,
liberty, and the pursuit of happiness as recognized by America’s founders are
viewed as absurd, because an imaginary God cannot declare rights.
Marxism demands that all so-called rights be issued by the government in the
form of laws.
And just as a law can be issued by the government, so shall it be taken away
by that government if deemed necessary.”
Brian Sussman, (2012). Eco-Tyranny: How the Left's Green Agenda will Dismantle America.
The environmental agenda has been infected by
extremism—it's become an economic suicide pact.
You must understand, the green agenda— from guano to global
warming— is not about celebrating the beauty of our planet; it is
an assault on mankind. It’s an agenda that has no regard for your
needs, lifestyle, dreams, desires, or feelings.
Brian Sussman, (2012). Eco-Tyranny: How the Left's Green Agenda will Dismantle America.
ENVIRONMENTALIST ACTIVISTS (eco-socialists) ARE DOGMATIC,
ideological radicals hell-bent on transforming society into a colossal,
highly regulated, redistributive commune void of inalienable rights. Their
lack of integrity enables them to look you straight in the eye and lie
about the facts, while they spin out tailor-made, cherry-picked research
supposedly proving their many fictitious claims regarding the state of
the global ecosystem. The primary goal of their green agenda is not a
pristine environment— it’s about gaining absolute control over your life.
Brian Sussman, (2012). Eco-Tyranny: How the Left's Green Agenda will Dismantle America
In June 1972, official representatives from 113 countries, hundreds of
nongovernmental organizations, and thousands of media outlets assembled in
Sweden to change the world.
The Declaration was nothing less than socialism cleverly cloaked in an ecological
wrapper—
“ reduce the gap” between the rich and poor;
 “shape our actions” by surrendering to nature;
 “demand the acceptance of responsibility” through heavy-handed government
regulations and laws.
It was a corrupted prescription written with the goal to one day
infect America.
Brian Sussman, (2012). Eco-Tyranny: How the Left's Green Agenda will Dismantle America
UNITED NATIONS Agenda 21 is a
carefully disguised attempt to hijack the
worthy cause of environmentalism in
the pursuit of political objectives.
