The Advocate, Feb. 19, 2013: Gary Hecox, a geologist with CB&I, said the cavern still is collapsing.

“The thing the committee needs to understand, the collapse is still ongoing today. The collapse is not finished. The seismic events that we’re monitoring demonstrate quite conclusively that the cavern is still collapsing.” -Gary Hecox

      **On the 200th day of the 8.6 acre La. “sinkhole” disaster area mandatory evacuation, when residents and officials packed the largest Senate committee room at the State Capitol and spilled into a second room for overflow, locals begged state legislators to persuade Texas Brine Co. LLC to buy their homes, conceding to another American sacrifice zone for the oil and gas industry.

      Oil and Gas industry human rights violation

      “Texas Brine has taught me more about purgatory and limbo, and I went to Catholic school, than the nuns could,” Candy Blanchard told legislators at a meeting in Baton Rouge, saying she will never feel safe at home again, according to Michelle Millhollon at the Advocate.**

        No one will ever be safe if they live next to either natural resources that will be extracted, or the waste from those operations.

        The US, as is all the rest, is slowly being strip-mined, and to hell with anyone that lives in the way.

        This is our future, until the radiation gets us.

    Even if there is a buy out TxBrn should not/ must not be allowed to walk away. The gas/oil leaking formations must be plugged, pressure relief wells must be drld. The void must be found and caused to fall in and the insuing sinklole reconfigured to form a viable lake.

    Anyone from the LA Senate Committee or B.C. residents interested in crafting the new language to define responsibilities of the Mining companies might review this. It comes from Pennsylvania Coal mining industry so may be parallel to your interests.

    "Methane is not specifically regulated under the Surface Mining Control and Reclamation Act of 1977 (Act). However, the Act at Section 521(a)(2) states that “When… any condition or practices exist which condition, practice, or violation also creates an imminent danger to the health and safety of the public the secretary shall immediately order a cessation of surface coal mining and reclamation operations or the portion thereof relevant to the condition, practice, or violation.”"

    skimming through this document, it looks like a very relevant paper to the cavern collapse.

    Page 36, same source as previous post:

    "a. >1.0% methane: One percent methane indicates that potentially explosive or flammable quantities of the gas or vapor are being liberated in the immediate environment. This concentration of methane should result in immediate evacuation of the premises and priority remediation. A sign should be posted on the premises at a location easily observable. This warning should include information that the concentration of methane is above 1.0 %, that smoking is prohibited, and that remediation is needed to reduce the methane concentration. Active ventilation would be considered the best option for immediate risk control."

    Thad, regarding methane migration through the claytard:

    Page 64 paragraph 5:
    "The same mechanisms that permit methane to enter shallow ground-water wells permit it to be released at the surface. Diffusion will force gas to migrate from areas of high concentration to areas of low concentration, even through low in permeability materials. Methane flows from high-pressure toward low-pressure areas. If the pore pressure for methane in the ground exceeds atmospheric pressure, it will flow to the surface. Soil texture, compaction, and geomorphology are factors that affect permeability and allow methane to migrate through or be stored in soil."
