The Coast Guard established the Inland Rivers Vessel Movement
Center (IRVMC) in St. Louis, April 16, to gather information and track
certain barges along the river system 24-hours a day.
In a continuous effort to secure the homeland, the Coast Guard increased its
presence and maritime. The Western River system tracks the movement of
barges containing certain dangerous cargoes from the new operational center.
Additionally, increased patrols, vessel escorts and/or boarding by river
marshals could be implemented based on the Department of Homeland Security
Advisory System level and other factors. These increased security measures
ensure the safe transit of vessels carrying certain cargoes, the safe
movement of commerce through specific portions of the river system and the
safety of strategic infrastructure.
