Tennessee Gas Pipeline
Tennessee Gas Pipeline (TGPL) is a set of natural gas pipelines which run from the Gulf of Mexico coast in Texas and Louisiana through Arkansas, Kentucky, Tennessee, Ohio, and Pennsylvania to deliver natural gas in West Virginia, New Jersey, New York, and New England. The pipelines were constructed by Tennessee Gas Transmission Company (TGT) beginning in 1943. Tenneco which owned TGT eventually sold off this pipeline which is now owned by El Paso Corporation. It is one of the largest pipeline systems in the United States. Its FERC code is 9.[1]
A 32 inch diameter gas transmission pipeline, north of Natchitoches, Louisiana, belonging to the TGPL, exploded and burned from stress corrosion cracking on the night of March 4, 1965, killing 17 people. At least 9 others were injured, and 7 homes 450 feet from the rupture were destroyed. This was the deadliest gas transmission pipeline accident in US history. This accident, and others of the era, led then-President Lyndon B. Johnson to call for the formation of a national pipeline safety agency in 1967. The same pipeline had also had an explosion on May 9, 1955, just 930 feet (280 m) from the 1965 failure.[2][3][4][5]
A TGPL 30 inch diameter gas pipeline failed at Natchitoches, Louisiana on November 30, 2010. There was no fire, but the pipeline had a Magnetic Flux smart pig test earlier in the year, that indicated no flaws in the pipeline. The failure was at a crack in a wrinkle bend. The deadly 1965 gas pipeline accident occurred on a different TGPL pipeline nearby.[6]
A TGPL pipeline in Columbiana County, Ohio (in eastern Ohio, near the Pennsylvania border, between Cleveland, Akron, Youngstown, and Pittsburgh) on Thursday, February 10, 2011, shot flames 200 feet into the air that were visible for 40 miles, and, before gas lines were shut down and it was put out, caused brush fires for a time. No fatalities or injuries were reported, and evacuated residents were returning to their homes by the next day. Another TGPL pipeline explosion happened on the morning of November 16, 2011, near Glouster, Ohio.[7][8]
Late on November 21, 2011, a TGPL 24 inch diameter gas transmission pipeline exploded and burned near Batesville, Mississippi. 20 homes were evacuated for a time, but there were no injuries or major property damage. The pipeline failed at a sleeve over a wrinkle bend installed in 1946.[9]
A major leak at a TGPL gas compressor station in Powell County, Kentucky on January 14, 2012 forced residents in the area to evacuate. There was no fire.[10]
