Texas Brine took Bayou Corne off its website list of brine storage locations.
In Louisiana they list 2 places, Grand Bayou, in NW Louisiana and White Castle. White Castle is just north from Donaldsonville.
We are just noting this location is under 12 miles from Bayou Corne –
Let’s look at The Cote Blanche Dome, in White Castle. Paper from THE CENTER FOR LAND USE INTERPRETATION (lots of information). They call the spot an injection field so maybe a lot of companies use it. We are looking around to see if Texas Brine just has a field office there or do they own a storage cavern there.
Here is a little more from 2014 – they were proposing to make a salt cavern there –
Critical events arising from the use of salt domes for brine production and storage purposes include the 1980 collapse of the salt mine on Jefferson Island and the closure of the Strategic Petroleum Reserve at Weeks Island due to sinkhole development. More recent events including the collapse of a brine cavern on the Napoleonville Dome and the proposed cavern storage of natural gas adjacent to an active salt mine at Cote Blanche.
This paper examines operations and concerns at Napoleonville and Cote Blanche. The Napoleonville Dome is used for brine production and storage of both natural gas and liquid petroleum gas. Underground mining of salt at Cote Blanche presents different concerns with proposed cavern construction and storage situated adjacent to mining operations. These operations emphasize the importance of understanding all aspects of safety and technical feasibility of using salt caverns for these purposes. Most critical is the need for accurate geological understanding of salt boundary and anomalous zones locations.
This next paper says Cote Blanche is in St. Mary Parish … but maybe it crosses Parish lines(?)
1993 paper from DOE on the Strategic Petroleum Reserves has some on Cote Blanche.
SUPPLEMENT TO THE DRAFT ENVIRONMENTAL IMPACT STATEMENT [DEIS] :
On page 17 they are talking about 24 wellheads. So maybe Texas Brine uses a part of the salt dome for their storage. We don’t know for sure.
A 2009 story – The IND – Cote Blanche salt dome eyed for natural gas storage
“The storage caverns would be located in the Cote Blanche salt dome, site of the North American Salt Co. at Cote Blanche Island. The salt mine company hired LSU civil engineering professor Robert Thoms to assess the risk to the mine workers. Thoms, a former adviser for FERC, found potential for the compressed natural gas to leak into the mine, putting the 150 salt mine workers in jeopardy.”
” . . . Three years ago, the U.S. Environmental Protection Agency declared that St. John the Baptist Parish had the highest cancer risk from airborne pollutants nationwide because of the “likely carcinogen” chloroprene.
Now, the most recent National Air Toxics Assessment conducted by the EPA notes dangers from ethylene oxide. Some areas on the east side of the Mississippi River, around St. Gabriel and Geismar, are at more than twice the risk for certain cancers as their neighbors on the west side, where there are fewer petrochemical facilities. The numbers are even more staggering downstream. . . “
” . . . We’ve been encouraging people (through Federal Flood Insurance, artificially-low interest rates and state/local greed) to move from the interior of the country to the coasts, raising the population density of sunny but stormy locales like the Carolinas and South Florida”
Water Emergency in Concordia Parish –
“Louisiana Gov. John Bel Edwards has declared a water emergency involving an east-central Louisiana water system after finding out that the system’s contracted operator is no longer running the system because it hasn’t been paid. The order involves the Clayton water system in Concordia Parish, which borders the Mississippi River in eastern central Louisiana. Health officials say without an operator, the water would become undrinkable in less than 24 hours.” . . . (more)
