Crosstex Energy LP of Dallas plans to begin on Tuesday shifting liquid butane from one underground storage cavern to another in the Napoleonville Salt Dome, moving the flammable product 1,000 feet farther away from a large sinkhole in northern Assumption Parish, company officials said.
The cavern now holding the 940,000 barrels of liquid butane is 1,500 feet from the sinkhole.
Sean Atkins, Crosstex vice president of compliance, [wrote that] the liquid butane “will not free-flow upward to the surface without a mechanical means for doing so, such as pumping.”
Atkins added later in the letter to Hatch, “Again, there has never been a catastrophic failure of a salt dome storage cavern resulting in an instantaneous release of butanes at the surface.”
Atkins’ letter says the worst-case scenario would be, in fact, a pipe failure releasing 8,400 gallons of butane that could lead to a level of pressure change, at nearly 1,600 feet, that parish officials have said would break windows.
John Boudreaux, director of the Assumption Parish Office of Homeland Security and Emergency Preparedness, said that pressure change could result from an ignition of the butane.
“In an abundance of caution, we have decided to make some piping changes and move product from the well closest to the slurry to the well farthest from slurry to further alleviate any concerns from public” -Jill McMillan, Crosstex spokeswoman
