Transmission pipelines are large steel pipes (usually 2″ to 42″ in diameter; most often more than 10″ diameter) that are federally regulated by the U.S. Department of Transportation. This type of pipeline carries unodorized gas at a pressure of approximately 200 to 1,500 psi. The pipe itself is constructed with 40′-60′ sections or “joints” that are welded together at the seams.
Transmission pipelines can fail due to: seam failures, corrosion, materials failure, or defective welding.
The natural gas transmission pipelines transport is unodorized therefore gas leaks can go undetected until an explosion occurs.

From 1994 through 2013, there were an additional 110 serious incidents with gas transmission, resulting in 41 fatalities, 195 injuries, and $448,900,333 in property damage.
A recent Wall Street Journal review found that there were 1,400 pipeline spills and accidents in the U.S. 2010-2013. According to the Journal review, four in every five pipeline accidents are discovered by local residents, not the companies that own the pipelines.
