12:55 p.m. Statement from Texas Brine, re: South Berm
Today, in discussion with and approval from DNR and APOEP, Texas Brine
has received permission to proceed with temporary repair work to the south berm in order to raise the height of the berm to protect against any immediate potential for overtopping due to subsidence. As part of this discussion, TBC has agreed to move forward with planning and submission of Emergency Use Authorizations and engineering designs for the installation
of a new southern containment structure. TBC will then proceed with the installation of this new southern containment system once the requisite permission and approvals have been received from DNR, DEQ, and APOEP.
The current south berm and containment system is still intact and
providing a continuous barrier between the waters inside and out of the sinkhole, but in an abundance of caution and due to recent seismic and
settlement activity the decision has been made to move forward with these new plans in order to ensure the long term containment of the sinkhole and any contaminants. TBC will also install two additional inclinometers
south of the current southern berm to provide additional data and early
warning of any movement due to subsidence in this area. Multiple layers of boom are also in place as redundant systems to provide protection against floating contaminants should any overtopping take place. Water quality testing is continuing to take place and consistently shows that the surface water quality within the containment berm is virtually the same as waters outside the containment berm.

Texas Brine advised that the tagging of Cavern 3 is at 4,076′ which is 66′ lower than the tagging performed two weeks ago. As information becomes available, it will be shared here.
- Monitored cracks in south berm daily during berm inspections
- Water transfer pumps on southwest berm continued to operate Tuesday – Thursday (12/3 – 12/5). Since November 5, a total of 43,092,000 gallons have been
transferred into the sinkhole from the surrounding swamp.
- Repair work on the south berm crack continued Tuesday and Wednesday (12/3 – 12/4). The crack was filled with grout and covered with clay, geotextile fabric, and

12 Noon Update from the Office of Conservation
Bayou Corne/Grand Bayou Response Activity
Thursday, Jan. 2 work-
Sinkhole Activity Code 3 – indicating no work is allowed directly on sinkhole or within containment berms. Seismic monitoring indicates further increase in levels of subsurface activity near sinkhole/Oxy 3 – state and parish will continue to closely observe seismic activity to advise of any sudden changes.
- Repairing and building up low areas on southern containment berm
- Re-stocking sand and gravel supplies for berm maintenance/repair
Just like before my twin brother's death, 9/11 and Fukushima, this has been making my nights restless. I don't do this often, but I'll put it out there... Watch the Gulf, I can't shake the feeling something is coming soon. My feeling is before March 1st. Being wrong would make me very happy, indeed.

10:45 a.m. Informational Meeting Scheduled, 01/14/14 @ 5:30 p.m.
An informational meeting will be held tomorrow at the Command Trailer in Bayou Corne at 5:30 p.m. An update of future activities, specifically the passive vent well program, will be given to residents. Texas Brine representatives will be on-site to present this information.
Sinkhole Activity Code 1 – indicating work is allowed on sinkhole and within containment berms. Seismic monitoring indicates continued low levels of subsurface activity near sinkhole/Oxy 3.
