DENVER - Today, the U.S. Environmental Protection Agency (EPA) released its 2021 Toxics Release Inventory (TRI) National Analysis, which shows that environmental releases of TRI chemicals from facilities across the nation covered by the program remained below pre-pandemic levels and releases in 2021 are 10% lower than 2012 releases, even with an 8% increase from 2020 to 2021. Additionally, in 2021, facilities managed more than 89% of their TRI chemical waste through preferred practices such as recycling, energy recovery and treatment, while reporting that they released 11% of their TRI chemical waste into the environment.

The report also reveals that EPA Region 8, which includes the states of Colorado, Montana, North Dakota, South Dakota, Utah and Wyoming and 28 Tribal Nations, has seen long-term decline in production related waste. In 2021, facilities in EPA Region 8 reported managing 919 million pounds of production related waste and releasing 349 million pounds of TRI chemicals into the environment. From 2012 to 2021, releases increased by 8.8% while production related waste decreased by 12.7%, both driven by the metal mining and primary metal manufacturing sectors.

Changes in the chemical composition of ore extracted at metal mines can result in large year-to-year changes in the amount of waste metal mines report to TRI. Excluding the metal mining sector, releases in Region 8 have increased by 7.7% since 2012. In 2021, 6.8% of facilities in Region 8 implemented new source reduction activities. Among sectors with the highest source reduction reporting rates were plastic and rubber manufacturing and machinery manufacturing.

“The Toxics Release Inventory is a valuable tool that provides detailed information about how chemicals are used and managed in our communities,” said EPA Regional Administrator KC Becker. “These data provide a high-resolution picture of how toxic chemicals are used, managed and disposed at hundreds of facilities across our region and can help inform significant pollution prevention activities, especially in our most overburdened and vulnerable communities.”

The 2021 TRI National Analysis summarizes TRI chemical waste management activities, including releases, that occurred during calendar year 2021. More than 21,000 facilities submitted reports on 531 chemicals requiring TRI reporting that they released into the environment or otherwise managed as waste. EPA, states and tribes receive TRI data from facilities in sectors such as manufacturing, mining, electric utilities and commercial hazardous waste management.

The 2021 Analysis features updated visualizations and analytical tools to make data more useful and accessible to communities, including the option to view data by region and watershed. EPA has also updated demographic information in the “Where You Live” mapping tool and in the Chemical Profiles section. Readers can view facility locations with overlayed demographic data to identify potential exposure to TRI chemical releases in vulnerable communities. Community groups, policymakers, and other stakeholders can use this data, along with other environmental data, to better understand which communities may experience a disproportionate pollution burden and take action at the local level.

In addition, this year the TRI National Analysis Sector Profiles highlights the plastic products manufacturing sector alongside the standard profiles for electric utilities, chemical manufacturing, and metal mining. This allows readers to learn about releases and waste management of TRI chemicals, as well as greenhouse gas emissions, from facilities in these sectors.

EPA is holding a public webinar on March 28, 2023, to give an overview of the 2021 TRI National Analysis. Register for the webinar.

Notable Trends in 2021

The National Analysis shows a 24% increase in the number of new pollution reduction activities facilities initiated from 2020 to 2021—a strong rebound after the decrease seen from 2019 to 2020. These activities include facilities implementing strategies like replacing TRI chemicals with less hazardous alternatives or reducing the amount of scrap they produce. Through both existing programs and the Bipartisan Infrastructure Law, EPA offers grant opportunities to state and tribal technical assistance providers to help prevent pollution.

Industry professionals can also look at TRI reporting on pollution prevention to learn about best practices implemented at facilities.

Ethylene Oxide Reporting

TRI reporting also shows a 45% decrease in ethylene oxide releases from 2012 to 2021, driven by decreased air emissions. Although there was a 15% increase in releases compared to 2020, quantities of ethylene oxide released in 2021 are lower than pre-pandemic quantities from 2019. EPA also expanded reporting requirements for ethylene oxide and other chemicals to include additional facilities. Reporting from these facilities will appear for the first time in next year’s National Analyses.

PFAS Reporting

For the second time, the TRI National Analysis includes reporting on perfluoroalkyl substances (PFAS) following the 2020 National Defense Authorization Act. For Reporting Year 2021, 176 PFAS were reportable to TRI. Facilities reported managing 1.3 million pounds of these chemicals as waste. This is an increase from the 800,000 pounds in 2020 and is largely due to reporting on one PFAS, perfluorooctyl iodide, which EPA began requiring facilities to report in 2021. Most of the facilities that manage PFAS operate in the chemical manufacturing and hazardous waste management sectors. The hazardous waste management sector accounted for roughly 80% of the 108,334 pounds of PFAS released into the environment, primarily to regulated landfills.

Last December, EPA proposed a rule that would improve reporting on PFAS to TRI by eliminating an exemption that allows facilities to avoid reporting information on PFAS when those chemicals are used in small, or de minimis, concentrations. Because PFAS are used at low concentrations in many products, this rule would ensure covered industry sectors and federal facilities that make or use TRI-listed PFAS will no longer be able to rely on the de minimis exemption to avoid disclosing their PFAS releases and other waste management quantities for these chemicals.
