NOAA
& Smithsonian Say U.S. Waters Safer From Invasive
Species If Ships Flush And Fill Ballast Water
At Sea
NOAA
and the Smithsonian released a technical report
today that finds ship captains can dramatically
reduce the supply of invasive aquatic species
delivered to U.S. ports, if they flush and refill
ballast tanks with ocean water before arrival.
The report describes the effectiveness of ballast
water exchange procedures as a way to reduce aquatic
invasive species discharged into U.S. waters,
including the Great Lakes and Chesapeake Bay.
If ports
are exposed to non-native species, these organisms
may establish themselves in the new habitat, like
zebra mussels and gobies in the Great Lakes, and
potentially cause harm to native populations of
aquatic animals and plants. An estimated 70 million
metric tons—roughly 50 million gallons per
day—of ballast water is discharged in U.S.
water annually.
“Research and
development to produce alternative ballast
treatment methods and technology-based ballast
treatment systems should continue to be pursued
as a high priority toward the reduction of
organism transfers,” said Richard Spinrad,
assistant administrator for NOAA Oceanic and
Atmospheric Research. “This report assesses what
is currently known about ballast water exchange,
and provides analysis of its likely effects.”
NOAA’s National
Center for Research on Aquatic Invasive Species
and Smithsonian Environmental Research Center
analyzed the delivery of ballast water to the
Great Lakes and Chesapeake Bay. These studies
indicate reductions in the risk of invasive
species introductions as a result of ballast
water exchange. The analysis provides further
confidence that overall, there has been a
decline in the risk of invasion from ballast
water in these regions. In addition, the report
addresses a potential gap in the coastal ballast
management protection framework whereas ships
traveling less than 200 miles from the U.S.
coast are not covered.
“Measurements made aboard ships during normal
operations demonstrate that ballast water exchange,
when properly conducted, can be highly effective,
removing or killing approximately 90 percent or
more of the coastal planktonic organisms from
most ballast tanks,” said David Reid, senior
physical scientist, NOAA National Center for Research
on Aquatic Invasive Species. “Some residual
coastal organisms may remain in ballast water
after exchange, and also in tanks with residual
water and sediments, both which may pose some
invasion risk during subsequent ballast discharge.
“It is clear that ballast water exchange
has significantly reduced species transfers and
invasion risk associated with ships’ ballast
operations,” said SERC senior scientist
Gregory Ruiz. “But the expected (albeit
reduced) rate of invasions for the organisms that
remain after exchange is not known. This represents
a gap in scientific understanding that limits
effective management decisions.”
The report suggests that a standardized survey
program, targeting key coastal ecosystems in the
U.S., could provide the high-quality data necessary
to (a) assess current invasion risk and (b) measure
the performance of multiple management actions,
including those of ships and other transfer mechanisms,
in terms of invasion occurrence. No such program
currently exists for the nation.

Key Democratic
Senators Pledge Support to Boaters
The boating industry claimed
a key victory in the Senate with ballast water
legislation.
U.S. Senators Barbara Boxer,
D-Calif., and Bill Nelson, D-Fla., unequivocally
committed themselves to resolve he issue before
a September 2008 permitting deadline.
“A recent court ruling
has cast doubt on whether recreational boaters
— people going out for a day of fishing,
or waterskiing — can continue to operate
without a permit from the EPA,” Nelson said
in a statement. “They’ve never been
required to have such a permit, and there’s
no reason for that to change. You shouldn’t
have to ask the EPA before you take your boat
out on the water.”
Environmental groups and several
states’ Attorney Generals successfully argued
in a U.S. District Court case last fall that ballast
water should not be exempted from government regulation
as a pollutant because it introduces harmful invasive
species into U.S. waters. Large ocean-going ships
use ballast water for stability, taking on water
to weigh the vessel down.
However, the court’s ruling
also includes boat-engine cooling water, bilge
water, gray water and common deck runoff. The
court directed the Environmental Protection Agency
to develop what the NMMA says is “a complex
and costly permitting scheme” for the nation’s
estimated 18 million boats by September 2008.
“I don’t think they
should have to get these permits,” said
Boxer, chairwoman of the Senate Environment and
Public Works Committee, in a statement. “I’ve
committed with Senator Nelson to make sure we
fix this before that time. We are going to make
sure that individual boaters do not need permits
— that’s as simple as it gets. That’s
my commitment, and it will happen.”
Walker Bay
Boats Adds Hypalon® to the Odyssey Air Floor
Line
Walker Bay Boats® Inc. announced
today that the Odyssey Air Floor Inflatable is
now also available in Orca® Hypalon®.
“The advantage of the Odyssey Air Floor
is that it can be rolled up & carried in its
own bag, making it the perfect stowable tender”
said Paul Roberts, VP of Sales and Marketing for
Walker Bay®. “Adding the Orca® Hypalon®
option makes the Odyssey more appealing to consumers
in extreme ultraviolet light regions.” The
new Odyssey Air Floor Hypalon® models will
be launched at the US Sailboat & Powerboat
Shows in Annapolis, MD October 4-14, 2007.
Walker Bay creates boats from
Orca® Hypalon®, the finest Hypalon®
material available. Four layers of calendared
sheets guarantee air-tightness (no porosity) and
optimal adhesion of rubbers. This combination
of materials provides improved weather resistance
against fading and aging as well as resistance
to fuel, oil and everyday abrasions. The tubes
are bonded using a three-layer process with all
seams internally and externally butted for maximum
reliability. Walker Bay® stands behind the
Hypalon® Odyssey Air Floor with a 10-year
fabric warranty.
The Odyssey Air Floor is a light,
compact boat that weighs 66 lbs for the 240 and
goes up to 99 lbs for the 340 and has five airtight
compartments. The Odyssey Air Floor comes in four
different sizes, 240, 270, 310 and 340 with capacity
of up to 5 people for the largest model. The new
Hypalon® Odyssey Air ranges from $1,699 for
the smallest model to $2,150 for the 340. Walker
Bay® will continue to offer the Odyssey PVC
models for the more casual user and those living
in regions where the UV exposure is not high.
Walker Bay® is available
in over 50 countries around the world and can
be found on the web at www.walkerbay.com
