Tank Car Hazards

Department: Letters

GLENN HESS'S excellent article about the Graniteville, S.C., disaster touched upon the implications for a potential terrorist use of poison-gas tank cars to kill thousands of target-city residents (C&EN, March 9, page 21). Not one poison-gas tank car has ever been designed to withstand terrorism, nor will the current much-touted effort make them so.

Even though railroads have only $1 billion in insurance for a disastrous $10 billion toxic gas release, they are still routing through and storing toxic gases in all 46 major U.S. target cities ("pre-positioning" as potential terrorist weapons) the 100,000-plus annual poison-gas rail cargoes that the federal government terms weapons of mass destruction. Chlorine Institute Pamphlet 74 says that one 90-ton tank car can produce a lethal toxic gas cloud 15 miles long and four miles wide. A chlorine production facility in Utah is recklessly shipping its product 2,000 miles to customers in Texas and Louisiana, where close-by chlorine facilities abound, as Union Pacific, which refuses to reroute, has piously pointed out in a petition to the Surface Transportation Board.

Some national experts, like Richard Falkenrath, now a top New York City counterterrorism official, see chemical security as the greatest single national vulnerability. Colorful railcar graffiti advertises the lack of rail security for dangerous cargoes.

U.S. railroads interchange cargoes with each other an estimated 6.5 million times each year but refuse to do so under worried cities' mandates for homeland security rerouting. As CSX Transportation concedes, since 9/11, the U.S. public has reconsidered what is an acceptable risk in urban freight railroading: "The support of the public, and of many policy makers, has greatly eroded since 9/11. Now the railroads are harshly criticized for transporting these [TIH, or 'toxic by inhalation' poison gas cargoes]. ... Our company's reputation has been assailed ... [and] vilified in the media. TIH [cargo] cannot simply continue to move by railroad indefinitely. ... Even if the potential for ruinous liability were somehow erased, the widespread social disapproval of TIH transport by rail would remain."

Chemical professionals should urge the Obama Administration and Congress to intervene immediately in the current secret railroad meetings in which individual railroads are unilaterally analyzing and selecting their urban hazmat routes. This sham process involves no significant input from state and local officials, as the National Conference of State Legislatures has protested.
