2012 TRI National Analysis

On February 4, 2014, EPA released the 2012 TRI National Analysis, an annual report that displays EPA’s analysis of the most recent TRI data.  It includes a variety of documents and Web sites that outline national and local trends in toxic chemical disposal or other releases to the environment, as well as trends in toxic chemicals managed by TRI facilities.  These resources include an overview of the National Analysis with additional context and explanation, briefing slides that show high-level messages and trends, and geographic-specific analyses that include highlights on urban communities, large aquatic ecosystems, and Indian country and Alaska Native Villages.  In Reporting Year 2012 (RY12), 21,024 facilities reported 3.63 billion pounds of toxic chemicals disposed of or otherwise released into the environment, down by 12% from 2011.  Between 2003 and 2012, facility disposal or other releases of TRI chemicals have decreased by 19%.

The National Analysis also includes data on hydrogen sulfide, following EPA’s lift of the Administrative Stay in 2011.  For RY12, 25.8 million pounds of hydrogen sulfide were reported to TRI mainly in the form of releases to air from paper, petroleum, and chemical manufacturing facilities.
