Despite those high rankings, Spectra Energy's environmental record is not without incidents or government imposed penalties. Since 2006, the Pipeline and Hazardous Materials Safety Administration reports twenty-five separate incidents at Spectra's Texas Eastern Transmission Pipeline ranging from equipment failure to incorrect operations to pipe corrosion. Combined, those incidents caused $12,036,495 in property damage, and the US federal government fined Spectra a total of $403,100 over that period. The most recent incident for that pipeline occurred on May 31, 2015 when a piece of the pipeline in the Arkansas River near Little Rock, Arkansas ruptured. Similarly the US federal government has imposed $154,700 in penalties since 2007 at Spectra's Algonquin Gas Transmission Pipeline for a single incident from 2010. An incident in 2010 from Spectra's Southeast Supply Header Pipeline did $561,563 in property damage, which led to it being fined a total of $201,300 by the US federal government.
