Rivers have been the life-blood of commerce in the United States since the
nation’s beginning. In 200 years, the machines of trade have evolved from flat-
bottomed wooden boats to today’s steel-hulled barges. The rivers link
America’s natural resources with the industrial cities that propel its economy.
Decades of damming and dredging have turned the big rivers into shipping
channels. But in recent years, competing interests have argued in defense of
other uses of the rivers. In the first of three reports, Kevin Lavery looks at how
those groups seek to balance the economy and ecology:


Long before interstates and over the road trucking, America moved its goods on
the water. River barges carry just about any kind of commodity. They emit less
pollution than trucks and trains… and the river route is cheaper than both the road
and the rail.


The nation’s farms, coal mines and quarries depend on rivers like the Mississippi,
Ohio and Missouri to keep their products moving. Business is healthy on the
Mississippi and the Ohio. But on the Missouri, barges carry just a third of the
cargo they did 30 years ago. Many shippers say drought and overregulated dam
releases make the water levels too unreliable to plan the big hauls that bring in
the most profit.


Paul Davis runs Interstate Marine Terminals, 200 miles upstream from where the
Missouri River meets the Mississippi, near St. Louis. He ships and stores
fertilizer from his dock. But Davis says when the river runs low, barges are not
his best option:


“The real adjustment that I’ve made is going from river to rail.”


Logistically, the adjustment is easy. The Union Pacific railroad line runs just a
few feet from Davis’ dock. But it costs him about 15 dollars more per ton to move
goods by rail. Davis says river barges might be profitable again if old feuds over
water management would end:


“There’s business out there. It could come back if people quit fighting and start agreeing
and confidence would return to shipping on the Missouri River. But I can’t afford to wait
and see… I’ve got to make adjustments.”


The fighting puts business against the environment. Shippers want enough
water to move freight. But environmentalists want the river to rise and recede
like it did before the Army Corps of Engineers started changing it.


The conflict goes back to the 1930’s. Congress ordered the Corps to make the
river safe for barges. That meant clearing snags and sandbars from a 735-mile
stretch from Sioux City, Iowa to St. Louis, Missouri. The Corps also confined the
river with earthen levees. Opponents say it turned the Missouri into a
characterless ditch.


The Corps spends 7 million dollars a year to maintain the channel. Spokesman
Paul Johnston says despite the dwindling volume of river traffic, the Corps is
mandated to keep the river open:


“The Corps of Engineers, like any federal agency, does not have the option to pick and
choose which laws it’s going to obey and not obey.”


But critics say wildlife has paid for the Corps’ mandate. Over the years, dams
and channels eliminated a half a million acres of wetland habitat. Birds lost their
sandbar nesting grounds, and fish no longer found shallow backwaters to lay their
eggs.


Among the hardest hit animals is the pallid sturgeon. It’s a long, flat-nosed fish
that dates back to the T-Rex. It’s been around 70 million years, and for the last
17, it’s been on the endangered species list.


Chad Smith directs the Nebraska field office of the environmental group
American Rivers. He says the pallid sturgeon’s fate shows the whole river is in
jeopardy:


“When it starts to decline, you know, that kind of creature that’s so in tune with the
Missouri as it was, is an indicator that maybe something’s not right, and it’s going to be
the first thing to fall.”


So Congress told the Corps to take on a recovery mission. The agency spends
more than 50 million dollars a year to rebuild shallow water habitat for fish and
birds. The Corps hopes a water resources bill pending in Congress will increase
its habitat restoration budget to 80 million dollars.


In 2006, the Corps launched its most controversial restoration program to date. It
released extra water from a South Dakota reservoir to mimic the natural flood
pulse that occurs on the Missouri River every spring. That triggers the sturgeon
to spawn.


Conservationists herald last year’s man-made spring rise as a long overdue sign
of progress. But barge companies on the lower Missouri are upset. They say
the spring rise brings a drop in the river’s depth in the summer… which means
less cargo they’re carrying and less money they’re making.

industry’s concerns over the Army Corps of Engineers’ control of the big

Using Energy More Efficiently

More and mores states are establishing a “renewable energy standard”
for their electric utilities. So far, wind power is producing the bulk
of renewable energy. But there are other sources. Some are brand new.
Others have been around for a long time. Stephanie Hemphill reports:


The first thing to know about electricity is that making it can be
incredibly inefficient.


In a conventional power plant, burning fuel turns water into steam.
The steam drives a turbine, which spins the generator. Only about a
third of the energy in the original fuel is converted to electricity.
Two thirds goes up the smokestack in the form of heat.


“Every time you convert energy from one form to another, you lose
something. That’s just the way it is, ’cause nothing’s perfect.”


Dwight Anderson works for Minnesota Power. He’s lived with that
inefficiency for his whole working life. Now, he’s trying to wring
more electric power out of every bit of fuel.


He’s high on something called co-generation. The basic idea is to
harness the heat or steam that normally goes up the smokestack.
There’s a good example of co-generation at the Sappi paper mill in
Cloquet, in northern Minnesota. Like many paper mills, Sappi makes
most of the electricity it needs.


Engineering Manager Rick Morgan points to a mountain of wood chips:


“We have about 20,000 tons of biomass stored.”


That’ll last less than a month. The plant uses 53,000 watts, enough to
power a small city.


Inside the sprawling buildings, there are several electric generators.
One of them is fueled by a recovery boiler, which burns the byproducts
of the paper-making process, to run steam through a turbine.


“…The actual turbine is manufactured in Czechoslovakia and the generator’s
made in Vestros, Sweden.”


Higher pressure steam spins the turbine to produce electricity. The
waste steam from the same boiler goes to the pulp dryer, the paper
machines, and other parts of the process.


Back in his office, Rick Morgan says energy is the fourth largest
expense for paper mills:


“If you can’t control energy costs in this business, you can’t be in
business.”


The main product here is paper, but sometimes Sappi sells electricity
too. That happened during a recent cold snap:


“The electric demand increases and the costs go higher and higher, to
the point that it’s financially feasible for us to generate power for
Minnesota Power.”


Opportunities to produce electricity turn up in some surprising places.
Like along natural gas pipelines. The pressure has to be boosted
periodically as the gas travels through the pipe. Compressors fueled
by the natural gas do that work, and normally they vent off waste heat.


But now in South Dakota, the waste heat is fueling small power plants.
They look like the barns and silos of a farm. The generator itself is
about the size of a truck.


Basin Electric Power Coop spokesman Daryl Hill says the plants are
owned and operated by an Israeli company, and the co-op buys the power:


“We get basically 22 megawatts of baseload for little investment.”


Other countries are leading in these approaches because their fuel
prices have been so high. As prices go up in the U.S., power producers
are finding ways to use more efficient technologies, and they’re
returning to old-fashioned ideas like combined heat and power. This is
a form of co-generation that was once common across the country.


A central electric plant uses its waste steam to heat buildings. Of
course, most people don’t want to live next to a coal-fired power
plant. But Neal Elliott, with the American Council for an Energy-
Efficient Economy, says with combined heat and power, cleaner fuels,
like natural gas, can become competitive:


“Use natural gas, but use it much more efficiently. And instead of
throwing more than half of the fuel value away, let’s do it with co-
gen.”


Elliott says combined heat and power and other forms of co-generation
could provide 20% of America’s electricity needs, and save on heating
fuel at the same time. And he says recovered energy generation like
along the natural gas pipelines could provide another 20%.

States are failing to stop the spread of an invasive insect that’s killing
millions of ash trees. The GLRC’s Rebecca Williams reports:


People are spreading the emerald ash borer into new areas. The destructive
pest was first discovered killing ash trees in southeast Michigan four years ago.
Moving infested wood has spread the bug to Ontario, Ohio and Indiana. Now,
Illinois officials say the ash borer is infesting trees west of Chicago.


Researchers say moving infested firewood is the fastest way the beetle spreads.
Several states have banned moving firewood from quarantined areas. States
as far away as South Dakota are warning out-of-state campers to keep firewood at
home.


Critics argue states are too lenient in enforcing the bans.


State officials say they’re struggling to keep up, as federal funding to
stop the ash borer is cut.


Researchers warn the ash borer could wipe out billions of ash trees if it’s not stopped.

Preserving Remnants of the Tallgrass Prairies

There’s an effort underway in western Minnesota to preserve the Midwest’s last remaining acres of northern tallgrass prairie. Once, the grasslands spanned close to 25 million acres through parts of Minnesota, the Dakotas and Iowa. More than 90% of the original tallgrass prairie was plowed under – what remains today are only patches of the early grasslands. Under a new U.S. Fish and Wildlife program the hope is to keep these last few areas intact for years to come. The Great Lakes Radio Consortium’s Gretchen Lehmann reports:
