    These arrived in my email this weekend. The only info is as stated. The only thing I can add is the file information shows the pictures were taken on 14th Sept 2008 and the ones on the ground were taken about 20mins before the arial shots by apparently the same camera.

    Is anybody aware of this disaster? QUOTE

    "This happened in the Mid West USA, wiped out two Farms killing one family of two adults, three children. The other farm lost the wife and one child the another child was burned and lost an arm, the father was working in a nearby paddock and was unhurt. The person who was Excavating was never found six other council workers on site died as well as two elderly ladies driving by. Fourteen dead in all, one badly injured, three slightly hurt. Only small bits of the Excavator Back Hoe was ever found." END QUOTE

    Just done a search and found exact same pics http://www.corribsos.com/index.php?id=2000

    Should have done the search first. Somebody has been playing with the statistics.
    According to the "official" reports, nobody was killed.

    They must have put the hush on that story, first I have heard about it. What a blowtorch, must have been a high pressure line to do that much damage.

    That is incredible! Anyone with a gas pipline running through their property would be very nervous if they saw those photographs.

    Thanks for posting these pics Atlas Rob. My thoughts and prayers to all affected.

    We have been working for a natural gas company for the past ten years or so and always here how bad it could be but I have never seen any devastation such as this. We actually are finishing a re-coat job in a wash out area this week. Just one slip or failure of the machine that is performing the digging can be catastrophic.

    I would certainly like to see what there findings are of what caused the accident. I wonder if they run smart pigs? How long was the line in the ground?

    If you come across any additional information please share.

    Thanks .......

    Rob,
    Do you know the source of this information?

    Apparently, thank God, it's not totally accurate....

    The reason no one heard of the story nationaly is because of the election. Not enough people killed, so no story, sad.

    Found some more info on story. The line was installed in 1955 and is one of three lines that run through the area. They have sent the piece of pipe to a metalurgy lab for testing. They suspect metal loss or corrosion. There was no work being done at that exact spot the explosion occured. They have been working on other areas of the line replacing sections and updating pumping staions. The gas is pumped through at 800psi, wow. They have lowered the other two lines pressure to 640psi until they have permission from the court to bring it back to full capacity of 800psi.

    If you go through the original post carefully I clarify that point with a statement at the end, after I had done a search.

    There is a lot of additional info by using the link I posted and working your way through the other links on that page. :drinkup

    I know some have dial up and it can take forever to follow links so this is COPIED & PASTED

    Preliminary findings by federal inspectors charged with investigating the rupture of a natural gas pipeline in Appomattox show some measure of metal loss near the failure, according to a corrective order issued last week to the company that operates the line.

    The order also listed concerns with corrosion-control systems along the line, and required the operator, Williams Gas Co., to lower the pressure in the two lines that run adjacent to the one that ruptured until a complete evaluation is done.

    The exact cause of last month’s pipeline rupture, which sparked a devastating fireball and leveled two homes, is not yet known. It is under investigation by the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration, the agency that issued the Sept. 25 corrective order.

    The natural gas pipeline that runs through Appomattox is part of the Transco line, which extends from the Gulf of Mexico to New York, including 858 miles in Virginia.

    Under normal operation, gas is pushed through those lines at 800 pounds per square inch. Williams immediately lowered the pressure to 670 psi after the Sept. 14 explosion. The corrective order requires Williams to lower it to 640 psi, which the company did last week.

    The order also outlines the steps needed to return the three natural gas lines to full service.

    “Most of the items covered were things we already planned to do,”

    :eek:That blowed up real good! Could have been hit 20-30yrs ago and finally let go. You can never be to careful, even a scratch can cause something like this after the fact.

    Here What The News Said.




    By CARRIE J. SIDENER and SARAH WATSON
    Published: September 14, 2008

    APPOMATTOX — Most Appomattox residents who were evacuated from their homes after Sunday’s gas pipeline explosion have been allowed to return, county officials said today.

    Some of those residents still don’t have power and were told they can stay in hotels until the power returns, officials said.

    Access to Virginia 26 just north of town, where the explosion occurred, remains blocked.



    he Transco pipeline, owned and operated by the Williams gas company, ruptured around 7:45 a.m. Sunday. The rupture was near a gas pumping station, and residents say the pipeline in that area had been under construction recently.

    A huge explosion followed, erupting into a fireball that demolished two houses and blistered the siding on homes 400 yards away.

    “It was what can only be described as a massive fireball, a quarter- to a half-mile tall and at least that wide,” said Appomattox County Deputy John Mattox, who was patrolling rural Log Cabin Road when the explosion occurred. “I couldn’t see to the other side of it because that fireball was so massive.

    “The concussion of it almost knocked me off my feet a quarter mile away, and the heat… I thought it was coming for me and I couldn’t get back fast enough.”

    The interstate pipeline was shut down immediately and firefighters could only contain the fire and let it burn while they evacuated the area.

    Five people were injured in the blast, but none of the injuries were life-threatening.

    Mattox immediately began pounding on doors, trying to wake residents and get them out of the path of the flames. Many heard the initial explosion and were struggling to wake up and figure out what happened. He was convinced with the size of the flames that more houses had been involved and that there had to be some fatalities. He said he is grateful that he was wrong.

    “I was telling folks to just run, to get in the car and run, don’t take anything, just go,” Mattox said.

    The aftermath of the explosion left a 15-foot crater in the ground just off Virginia 26. A portion of the natural gas pipeline was mangled and blown across the road into what used to be a grassy field. The field is now barren dirt.

    The lettering on the street sign at Kelly Creek Lane melted and appeared to be almost dripping off the sign after the fire.

    The pipeline runs from the Gulf of Mexico to New York — more than 10,500 miles of 36-inch pipe. The cause of the rupture and subsequent explosion is still under investigation both by Williams and state and federal officials.

    “Certainly, this is a serious incident and Williams employees are doing everything they can to ensure public safety,” said Randy Barnard, Transco’s senior executive for operations. “We are very concerned about the report of injuries and the property damage. Our thoughts and prayers are with those who have been
    affected.”

    Stuart Roach, district manager for Williams, said employees were on the scene once the fire burned out to examine the damage and look for clues.

    “We still have a lot of facts to gather,” Roach said. “There will be an investigation of the scene to determine what caused the failure.”

    Twelve homes were evacuated, said Sgt. David Cooper of the Virginia State Police. A shelter set up by the American Red Cross and Appomattox County at Appomattox County High School served more than 40 people. Williams sent those who could not return to their homes to local hotels.

    Bobby Wingfield, director of public safety for Appomattox County, said the pipeline has built-in fail-safes that automatically shut off the gas when a rupture is detected and alert the gas company. Those fail-safes prevented the explosion from gaining magnitude.

    “Nothing like this has ever happened before as far as I know,” Wingfield said. “We never want something like this to happen, but there are plans in place.”

    Flames shot in the air in excess of 300 feet, said Sheriff Wilson Staples. The flames were visible in the town of Appomattox more than a mile away.

    More than 100 firefighters responded from Appomattox and neighboring counties including Buckingham County Fire and Rescue, Gladstone Fire and Rescue, Concord Fire and Rescue, Appomattox Fire and Rescue, Red House Fire, Pamplin Fire and Rescue and Amherst County Emergency Services, along with the regional hazardous materials team, the Virginia Department of Emergency Management and the Virginia State Police.

    The heat and flames were intense enough to spawn a separate grass fire that was quickly contained, said Timothy Garrett, of the Appomattox Fire Department.

    Neighboring houses were evacuated as a precaution while firefighters worked to contain the blaze, Garrett said.

    The Virginia Department of Emergency Management and the Appomattox Fire Department tested the air all afternoon for any other possible leaks, said Vicky Phelps, spokeswoman for the county. No further leaks were found.

    Virginia 26 will remain closed until the Virginia Department of Transportation can inspect the road and determine if it is still stable, Wingfield said. That will only happen after the investigation is complete.

    I have a job repairing a field tile over the top of a similar pipeline. There are 2 30" and a 36" high pressure mains that are running 858 psi. I met with the guys from Trans-Canada & we had to hand dig down & find thier pipeline as well as our tile. We are going out tomorrow,hopefully,to repair our drain. I have 3 guys coming in to go hand dig 3' deep & 10' long to fix. This is the same pipeline that around 15 years ago exploded from a contractor hitting it with a tile trencher. I was told that the only machinery allowed was to be used for backfilling.:eek:
