This update is the 12th article in this Opednews series about the Bayou Corne sinkhole.
BACKGROUND: In Spring of 2012, Louisiana's Corne and Grand Bayou residents noticed strange bubbling in the bayou for many weeks, and they reported smelling burnt diesel fuel and sulfur. Then suddenly a sinkhole the size of three football fields appeared on Aug. 3, swallowing scores of 100-foot tall cypress trees. The sinkhole resulted from the failure of Texas Brine Company's abandoned underground brine cavern. The Department of Natural Resources issued a Declaration of Emergency on Aug. 6, and 150 families were evacuated.

The access ramp from the Oxy 3 well pad to the sinkhole has reportedly been lost in the cave-in, along with a number of trees adjacent to the ramp.
The announcement, in full:
The Office of Conservation, in consultation with Assumption Parish Incident Command, is advising the public that the Oxy 3/sinkhole monitoring alert status has been raised to Code 2 -- requiring all work directly in and over the sinkhole to cease until further notice. Seismic monitoring has detected elevated subsurface activity in the area around the sinkhole and Oxy 3 area indicative of fluid and gas movement below the sinkhole, and a further slough-in was observed along the southeastern side of the sinkhole this morning, with the access ramp from the Oxy 3 well pad to the sinkhole having sloughed in, along with several trees on either side of the ramp.
