DEQ says the Texas Brine is in compliance, but the what-if ramifications if the salt dome has failed are sobering, indeed.
The Louisiana Department of Environmental Quality has asked the operator of a salt cavern near a sinkhole in northern Assumption Parish to describe what would happen if all butane that could be held in the underground storage facility were released to the surface, state officials said Tuesday.
DEQ Secretary Peggy Hatch asked for the updated worst-case scenario from Crosstex Energy LP of Dallas by close of business Wednesday after reviewing the company’s current risk management plan for the cavern, state officials said in a news release.
The Crosstex salt cavern, which holds 940,000 barrels of liquid butane under pressure, is 1,600 feet from the sinkhole on the adjacent Texas Brine Co. LLC property south of La. 70 south.
DEQ officials said Tuesday there are “a lot of dynamic things” happening around the butane cavern, including expected well drilling, and community concerns have arisen.Jill McMillan, spokeswoman for Crosstex said:
....
DNR scientists suspect the Texas Brine cavern may have been carved too close to the edge of the Napoleonville Dome and failed, releasing its brine contents and causing the sinkhole.
....
DEQ officials said Crosstex’s updated plan submitted in January considers risks for butane, natural gas and other gases and suggests a full release might lead to windows being broken at two-thirds of mile. Piehler said two-thirds of a mile is close to the Bayou Corne community, which has about 150 residences, but does not actually include it.
“Based on these findings to date, we believe our facilities have not been impacted by the slurry-filled sinkhole, and there has been no indication their integrity has been compromised,” she said in the email.Let's hope and pray that none of the worst-case scenarios happen, nor a scenario that none of the experts have thought of, and we hear the lament, "Who would ever have expected...?" That amount of butane under pressure sounds quite dangerous to me, and I hope the authorities are not playing down the seriousness of the situation as authorities are wont to do.
For those of you who may be concerned about us, we are about 30 miles away from the site and presumably safe.
Thanks to MM for his concern. I planned to post on the situation yesterday but never got around to it.
