State wants updated risk plan on nearby cavern
State agencies say they've asked the company owning a natural gas pipeline that was bent by an expanding sinkhole in Assumption Parish for an updated risk management plan on a nearby butane storage cavern.
Crosstex Energy LP of Dallas owns a storage cavern 1,600 feet from the site of a sinkhole near Bayou Corne. The cavern houses 940,000 barrels of butane.
Department of Environmental Quality Secretary Peggy Hatch says she's asked for an updated worst-case analysis out of "an abundance of caution." She said Tuesday that she wants the analysis to include the possible release of the largest amount of butane in the cavern.
Officials say they expect the analysis to be in by Wednesday.
The sinkhole sits on the edge of a brine cavern owned by Texas Brine Co.
