Toxic Release Inventory (TRI)

Toxic releases in the U.S. decreased by 6% in 2015 and remained below our target of less than one million pounds. Air emissions and hazardous air pollutants (HAPs) continued to decrease due to improved leak detection and repair systems put in place in 2014.  

Methodology changes also contributed to the decline in estimated air emissions, as well as the increase in releases to land. Releases to water increased in 2015 due to operational changes at a water treatment system at one of our facilities.
