of preventing terrorist attacks within or
exploitation of the U.S. maritime trans-
portation system (MTS). To accomplish
this the Coast Guard with its many securi-
ty partners have implemented a risk-based
approach to identify and secure critical
infrastructure within the MTS and to tar-
get possible threats to maritime security.
To this end, the Coast Guard is partnering
with the rest of the intelligence communi-
ty to identify possible threats well before
they reach U.S. shores. The result is a
multi-layered, multi-agency international
security operation that attempts to inter-
cept terrorist activities overseas, again at
the nation's entry points and once more in
the vicinity of critical infrastructure while
hardening the physical security at these
pieces of infrastructure to withstand an
attack should all else fail. A strategy that
must be implemented within the con-
straints of fiscally responsible budgets,
preservation of civil liberties and ensuring
the flow of legitimate maritime commerce
so vital to this nation's economy. Securi-
ty of the Western Rivers, led by the Eight
Coast Guard District, is an important
component of this maritime homeland
security strategy.
The vast expanse of the Western Rivers
consisting of 41 rivers and lakes across 18
states throughout the heartland of the
United States poses a tremendous security
challenge. This inland MTS centers on
the Mississippi River and its major tribu-
taries including the Ohio, Illinois, Mis-
souri, Arkansas, Tennessee and Cumber-
land Rivers (over 10,300 miles of naviga-
ble waterways). These rivers flow
through the states of Pennsylvania, Ohio,
West Virginia, Kentucky, Nebraska, Ten-
nessee, Indiana, Arkansas, Iowa, Kansas,
Missouri, Oklahoma, Louisiana, Missis-
sippi, Alabama, Illinois, Minnesota and
Wisconsin. These waterways are an inte-
gral part of a complex inter-modal trans-
portation system, which moves bulk car-
goes and manufactured goods for foreign
and domestic commerce. They provide a
channel into the nation's heartland, con-
necting the Gulf Coast with the coal and
steel industries of Pittsburgh, Pennsylva-
nia; and the grain exporters of the Twin
Cities, Minnesota.
The inland waterways system allows
the competitive movement of huge quan-
tities of liquid and dry bulk cargoes
between deepwater ports and distant
points of production or consumption in
the nation's interior. In recent years, U.S.
inland waterways traffic has approximat-
ed 630 million tons annually)-accounting
for about 15 percent of total intercity com-
merce by volume. Total inland waterways
traffic is forecast to increase 1.3 percent
annually to more than 836 million tons by
2020 with principal commodity groups
including coal, petroleum, farm products,
chemicals, and crude materials, such as
aggregates for construction and other
minerals. Each inland barge carries as
much cargo as 150 tractor-trailer trucks or
40 rail hopper cars. A typical tow of 15
barges has the capacity of 2,250 trucks or
600 rail cars. The Federal Highway
Administration estimates that for each 1
million tons of coal diverted from barge to
truck, 45,600 additional trucks would be
needed to move the coal. The Tennessee
Valley Authority estimated the average
transportation savings of shipping by
barge versus alternate mode of transport
to be $6.92 per ton for coal, $29.65 per
ton for chemicals and averaged $10.54 per
ton for all cargo. The inland waterway
cargo-carrying fleet includes 2,500 tank
barges. There are also 25,000 dry cargo
barges. A fleet of 5,200 towboats and tug-
boats supports the barge fleet. The fleet
travels the inland waterways by using
more than 170 lock sites. There are more
than 1,700 river terminals along the West-
ern Rivers. 59 percent of inland terminals
are grain, coal and other dry bulk facili-
ties. Liquid bulk terminals account for 27
percent; half of which are petroleum facil-
ities. The terminals on the inland system
are less concentrated geographically and
provide almost limitless access points to
the waterways.
The task of securing this transportation
system is perhaps one of the Coast
Guard's most complex challenges. Not
only are multiple jurisdictions involved,
the sheer length of the transportation sys-
tem is daunting. To respond to this chal-
lenge the Coast Guard through the Eighth
Coast Guard District command located in
New Orleans has initiated three major
programs, which when combined, signifi-
cantly increases maritime security, mar-
itime domain awareness and interoper-
ability with the public and commercial
operators.
In perhaps one of the most under publi-
cized homeland security initiatives, the
Inland River Vessel Movement Center
(IRVMC) was created. In response to
direction from the Department of Home-
land Security and in consultation with the
maritime community operating on the
rivers, IRVMC, located in St Louis, was
established in 2003 to help develop
greater maritime domain awareness
(MDA) on the Western Rivers through the
tracking of Certain Dangerous Cargoes
(as specified by regulation) that are car-
ried in barges. Each year IRVMC tracks
over 36,000 transits of barges carrying
these hazardous cargoes, at 94 individual
reporting points, over 10,300 miles of the
inland rivers, including thousands of tran-
