TRI and Beyond

The Toxics Release Inventory (TRI) is a powerful resource that provides the public with
information about how TRI chemicals are managed by facilities in the United States. However,
there are many other programs at EPA that collect information about chemicals and the
environment.

The next figure is an overview of some of the laws that EPA implements, and the industrial
activities or processes EPA regulates under these laws. While many programs at EPA focus on
one area, TRI covers releases of chemicals to air, water, and land; waste transfers; and waste
management activities. As a result, TRI data are especially valuable, as they can be utilized with
many other datasets to provide a more complete picture of national trends in chemical use,
chemical management, environmental release and other waste management practices, and
environmental performance.

Throughout EPA, offices use TRI data to support their mission to protect human health and the
environment. These uses include analyzing TRI data to inform decisions such as when setting
program priorities, providing information to stakeholders such as when working with
communities toward a common goal, and many other applications.

This section of the National Analysis highlights how TRI data complement Toxic Substances
Control Act (TSCA) data and risk evaluations, and how TRI has served as a model for other
pollutant release and transfer inventories around the world.

As with any dataset, there are several factors to consider when using the TRI data. Key factors
associated with data presented are summarized in the Introduction. For more information see
Factors to Consider When Using Toxics Release Inventory Data.

TSCA and TRI

The Toxic Substances Control Act (TSCA1. as amended by the Frank R. Lautenberg Chemical
Safety for the 21st Century Act, is the nation's primary chemicals management law. Under
TSCA, existing chemicals in commerce and new chemicals intended for use in commerce are
reviewed for safety through a risk-based process with increased public transparency.

The three stages of EPA's process for evaluating the safety of existing chemicals are
prioritization, risk evaluation, and risk management. During both the prioritization and risk
evaluation stages of the process, TRI serves as a source of information, as illustrated in the
figure below.

Prioritization. Approximately two-thirds of the chemicals identified in the 2014 update of the
TSCA Work Plan are also included on the TRI list of chemicals. TRI is well suited to help inform
prioritization of chemicals for risk evaluation because TRI data contain information on release
quantities of TRI chemicals to air, water and land, and the locations of these releases, and are
submitted annually. Note that designation as a TRI chemical by itself does not determine high
or low priority for a chemical.

Risk evaluation. A TSCA risk evaluation of a chemical is a comprehensive evaluation of the
risk the chemical poses to human health and the environment over the chemical's life cycle. The
conditions of use for the chemical are evaluated, which may include manufacturing and import,
processing, use, and disposal. During risk evaluation, EPA is required to assess occupational
exposure, as well as general population exposure, and exposure to ecological receptors that
may be sensitive to the potential hazards posed by the chemical under review. The TRI is a
useful source of information for assisting in estimating these exposures, as it contains release
quantities of TRI chemicals to air, water, and land, the locations of these releases, as well as
information on use and waste management practices that may lead to exposure.

EPA uses TRI data as an information source to estimate and analyze environmental releases
from industrial uses of the chemical in the risk evaluation. The figure below provides an
example of a water release assessment for a chemical throughout the multiple phases of its
industrial life cycle. At each life cycle phase, both the number of sites and quantity released are
determined based on the TRI data. The release assessment estimates the amount of the
chemical entering the environment, which can subsequently be used to model exposures of
general populations and environmental species for each condition of use. To complete the risk
evaluation stage, EPA makes a risk determination stating whether a chemical substance
presents an unreasonable risk to human health or the environment under its conditions of use.

Management. If EPA determines that a chemical presents an unreasonable risk to human

health or the environment, EPA will evaluate options for mitigating the risks. EPA is required to
implement, via regulation, restrictions on the manufacture, processing, distribution, use and/or
disposal of the chemical to eliminate the unreasonable risk. EPA is given a range of risk

management options under TSCA, including labeling, recordkeeping or notice requirements,
actions to reduce human exposure or environmental release, or a ban of the chemical or of
certain uses of the chemical. TRI data, such as on chemical use and pollution prevention, may
be used to inform these risk management decisions.

Chemicals to be Evaluated under TSCA

In 2017, EPA published the scope of the risk evaluations to be conducted for the initial ten
chemicals undergoing risk evaluation under the amended TSCA. Of these ten chemicals, seven
are fully covered on the TRI list of chemicals, two are partially covered by TRI, and one is not
on the TRI chemical list. For the TRI-listed chemicals, TRI can provide valuable information to
the TSCA assessment process and serves as a tool for tracking the nation's progress toward
reduced environmental releases. This figure shows the trend in TRI-reported releases of the
TSCA chemicals currently undergoing risk evaluation that are fully TRI-listed.

TRI Around the World

In 1986, the TRI Program was established as the first national Pollutant Release and Transfer
Register (PRTR) in the world. Since then, environmental agencies around the world have been
increasingly implementing their own PRTR programs with the Toxics Release Inventory (TRI)
serving as a model. Currently, at least 50 countries have fully established PRTRs or have
implemented pilot programs, as shown in the map below. More are expected to be developed
over the coming years, particularly in Asian, South American, and African countries.

No Information

Source: United Nations Economic Commission for Europe, 2016

As global PRTR implementation continues to grow, the TRI Program will continue to work with
international organizations to:

•	Assist in the development of PRTR programs in other countries

•	Encourage other countries to develop initiatives aimed at making existing PRTR data more
comparable to allow better analysis of the data on a global scale

•	Make PRTR data more useful for assessing progress towards sustainability

For information on international PRTR activities, projects and partners, see TRI's International
weboaae As an example, the TRI Program is currently working with the Organization for
Economic Co-operation and Development fOECDl |BfiT on a project to use global PRTR data to
assess progress toward the Sustainable Development Goals established in the United Nation's
2030 Agenda for Sustainable Development EXIT, as described in the Project Spotlight below.

International Project Spotlight:

Using PRTR Data to Assess Progress toward the U.N. Sustainable Development Goals

Background. The TRI Program is participating in a project to use global PRTR data to assess progress
toward the United Nations' fU.N.I Sustainable Development Goals fSDGsl. These goals are
designed to "shift the world on to a sustainable and resilient path" by setting targets that encompass
the economic, environmental, and social dimensions of sustainability. As countries and stakeholders
take action toward achieving the SDGs, the U.N. will measure progress toward the Goals using
existing data where possible. One such existing data source for some of the SDGs may be found in

countries' established PRTR data.	

Project Objectives. The project applies and demonstrates the utility of PRTR data to inform SDGs and
has three complementary objectives:

•	Developing approaches for using PRTR data for global-scale sustainability analyses,

•	Assessing progress towards meeting specific SDG targets through examination of global
chemical pollution trends, and

•	Accelerating progress towards meeting specific SDG targets by investigating the drivers of
observed trends and providing an opportunity for knowledge transfer among countries facing

	similar chemical pollution challenges.	

Initial Focus. The U.N. SDG
Target 12.4 was identified as the
target most directly relevant to
PRTR data and is the focus of this
initial phase of the project. This
target focuses on reducing
chemical releases to the
environment.	

Project Status. Global analyses of PRTR data are currently underway to aggregate data for multiple
chemicals from multiple countries in order to recommend possible metrics to track progress in
reducing chemical releases to the environment. A sample figure below shows the trend for 14
pollutants as reported to 7 PRTRs.

SDG Tarset 12.4

By 2020, achieve the environmentally sound management of
chemicals and all wastes throughout their life cycle, in accordance
with agreed international frameworks, and significantly reduce their
release to air, water and soil in order to minimize their adverse
impacts on human health and the environment.
