SAN FRANCISCO — Today, the U.S. Environmental Protection Agency released its annual Toxics Release Inventory (TRI) National Analysis, which shows releases of toxic chemicals into the air fell 56% from 2005-2015.

Of the over 443 million pounds that were disposed of or otherwise released to the environment in the Pacific Southwest Region, approximately 94 percent went to land, 3 percent to air, less than 1 percent to water, and 2 percent was transferred to other facilities.

"In 2015, nearly 1,700 facilities submitted data to EPA’s Toxic Release Inventory in the Pacific Southwest region,” said Alexis Strauss, EPA’s Acting Regional Administrator for the Pacific Southwest. “It’s crucial for communities to have access to this valuable data and year-to-year trends.”

In the TRI, a "release" generally refers to a chemical that is emitted to the air, water, or placed in some type of land disposal unit. Most of these releases are subject to a variety of regulatory requirements designed to limit human and environmental harm.

Pacific Southwest highlights:

California:  A total of 1,242 California facilities reported 334.7 million pounds of production-related chemicals, a decrease of 233.8 million pounds when compared to 2014 data. Clean Harbors in Buttonwillow and Chemical Waste Management in Kettleman City were the top two facilities for total on-site and off-site releases.

EPA, states, and tribes receive TRI data annually from facilities in industry sectors such as manufacturing, metal mining, electric utilities, and commercial hazardous waste management. Under the Emergency Planning and Community Right-to-Know Act (EPCRA), facilities must report their toxic chemical releases for the prior calendar year to EPA by July 1 of each year. The Pollution Prevention Act also requires facilities to submit information on pollution prevention and other waste management activities of TRI chemicals. Nearly 22,000 facilities submitted TRI data for calendar year 2015.

The TRI National Analysis website includes new interactive features such as an automated “flipbook” [https://www.epa.gov/trinationalanalysis/30-year-anniversary-tri-program-slideshow] depicting how the TRI Program has evolved over the past 30 years, and a new embedded dashboard that allows users to build customized visualizations of TRI data by a chemical or a sector. These features are intended to promote more user engagement and exploration of TRI data.
