Introduction to the 2017 TRI National Analysis

Industries and businesses in the United States (U.S.) use chemicals to make the products we
depend on, such as pharmaceuticals, computers, paints, clothing, and automobiles. While the
majority of chemicals included on the Toxics Release Inventory (TRI1 chemical list are managed
by industrial facilities to minimize releases into the environment, releases do still occur as part
of their normal business operations. It is your right to know what TRI chemicals are being used
in your community, how they are managed, how much is released into the environment, and
whether such quantities are increasing or decreasing over time.

The TRI is a publicly available database maintained by EPA that tracks the management of
certain chemicals. The information contained in the TRI is submitted by facilities in the U.S. in
industry sectors such as manufacturing, metal mining, electric utilities, and commercial
hazardous waste management. Under the Emergency Planning and Community Riqht-to-Know
Act fEPCRAl. facilities must report details about their releases of TRI-listed chemicals for the
prior calendar year to EPA by July 1 of each year. The Pollution Prevention Act fPPAl requires
facilities to include in their report submissions information on pollution prevention and other
waste management activities involving TRI chemicals. For calendar year 2017, more than
21,000 facilities submitted TRI data to EPA.

Each year, EPA prepares and publishes the TRI National Analysis. In support of EPA's mission to
protect human health and the environment, the TRI National Analysis summarizes recently
submitted TRI data, explores data trends, and interprets the findings.

Highlights from the 201 7 TRI data

As an overview, the two charts below summarize the most recent TRI data on: 1) how chemical
wastes were managed in 2017; and 2) how the portion of wastes that were disposed of or
otherwise released were handled.

• Facilities reported managing 30.57 billion pounds of TRI-listed chemicals as production-
related waste. This is the quantity of TRI chemicals in waste that is recycled, combusted for
energy recovery, treated, disposed of, or otherwise released into the environment. In other
words, it encompasses the TRI chemicals in waste generated from the production processes
and operations of the facilities.

o Of this total, 87% was recycled, combusted for energy recovery, or treated. Only
13% was disposed of or otherwise released into the environment.

•	For chemical wastes that were disposed of or otherwise released, facilities also reported
where the wastes were released—to air, water, or land (on site or off site). Most waste was
disposed of on site to land (including landfills, other land disposal, and underground
injection).

•	As highlighted in the Releases of Chemicals section, releases to air continued to decline in
2017. Since 2007, air releases reported to TRI have decreased by 57% (757 million
pounds).

What's in the 2017 TRI National Analysis

The Toxics Release Inventory (TRI) National Analysis is prepared and published annually, and
the 2017 TRI National Analysis is EPA's summary and interpretation of TRI data reported for
activities that occurred at facilities in the U.S. during 2017. It offers valuable information for
improving our understanding of how the environment and communities may be affected by TRI
chemicals and is a snapshot of the data at one point in time. To conduct your own analysis of
TRI data, use the most recent data available on the TRI Data and Tools webpaae.

Additional information is presented in the following sections of the TRI National Analysis:

•	Pollution Prevention and Waste Management presents the types of pollution prevention
activities that facilities have implemented, and trends on recycling, energy recovery,
treatment, and releases of TRI chemical waste generated and managed as part of
industrial operations.

•	Releases of Chemicals presents trends in releases of TRI chemicals to the air and water,
and disposed of to land, including a focus on selected chemicals of special concern.

•	Industry Sectors highlights TRI chemical waste management trends for five industry
sectors: manufacturing, paint and coating manufacturing, chemical manufacturing,
metal mining, and electric utilities.

•	Where You Live presents analyses of the TRI data specific to U.S. geographic areas:
state, city, county, ZIP code, metropolitan area and micropolitan area, and by Large
Aquatic Ecosystems (LAEs), such as the Chesapeake Bay, as well as information about
facilities in Indian Country.

•	TRI and Beyond presents TRI data used in conjunction with data from other
environmental programs, such as chemical production data reported to EPA under the
Toxic Substances Control Act (TSCA). The use of TRI as a model for other pollutant
release and transfer inventories around the world is also discussed in this section.

TRI Data Considerations

As with any dataset, there are several factors to consider when reviewing results or using the
Toxics Release Inventory (TRI) data. Key factors associated with data presented in the TRI
National Analysis are summarized below; for more information see Factors to Consider When
Using Toxics Release Inventory Data.

•	Covered sectors and chemicals. TRI includes information reported by many industry
sectors on the quantities of many chemicals that are released or otherwise managed as
waste, but it does not contain such information on all chemicals manufactured,
processed or otherwise used by facilities or from facilities in all industry sectors within
the United States. A list of the sectors covered bv the TRI Program is available on the
TRI webpage, as well as a current list of the chemicals reportable to the TRI Program.

•	TRI trends. The list of TRI chemicals has changed over the years; as a result, trend
graphs in the TRI National Analysis include only those chemicals that were reportable for
the entire time period presented so that the year-to-year data are comparable. Results
which focus only on the year 2017 include all chemicals reportable for 2017. Thus, the
results for 2017 analyses may differ slightly from results presented in trend analyses,
which include 2017 and previous years.

•	Data quality. Facilities determine the quantities of chemicals they report to TRI using
best available data. Each year, EPA conducts an extensive data gualitv review that
includes contacting facilities to review potential errors in reported information. This data
quality review ensures the National Analysis is based on accurate and useful
information.

•	Risk. The quantity of TRI chemicals released is not an indicator of health risks posed by
the chemicals. Although TRI data generally cannot indicate the extent to which
individuals may have been exposed to chemicals, TRI data can be used as a starting
point to evaluate the potential for exposure and whether TRI chemical releases might
pose risks to human health and the environment. In particular, note that:

o The level of toxicity varies among the covered chemicals; data on amounts of the
chemicals alone are inadequate to reach conclusions on health-related risks; and
o The presence of a chemical in the environment must be evaluated along with the
potential and actual exposures and the route of exposures, the chemical's fate in
the environment and other factors before any judgements can be made about
potential risks associated with the chemical or a release.

For more information on the use of TRI data in exposure and risk analyses, see Factors
to Consider When Using Toxics Release Inventory Data and the Hazard and Potential
Risk of TRI Chemicals in the Releases section.

•	Late submissions. TRI reporting forms submitted to EPA after the July 1 reporting
deadline may not be processed in time to be included in the National Analysis. While
revisions can be submitted after the July 1 reporting deadline, the data used to develop
the National Analysis is frozen in mid-October. Therefore, revisions received after this
freeze date will not be reflected in the National Analysis. Those late revisions will be
incorporated into the TRI dataset during the Spring refresh of the data and will be
reflected in next year's National Analysis when it refers to 2017 data.

•	Double-counting. The National Analysis presents summaries of many quantitative data
elements (see "Quick Facts" below) including releases to the environment, which occur
on site and off site after wastes are transferred to other businesses for further waste
management. When aggregating releases across facilities, such as national totals, EPA
adjusts off-site releases to eliminate double counting of releases if the receiving facility
also reports to TRI.

One of the reasons total disposal or other releases is lower is that it removes "double
counting" that occurs when a facility that reports to EPA's TRI Program transfers waste to
another TRI-reporting facility. For example, when TRI Facility A transfers a chemical off site
for disposal to Facility B, Facility A reports the chemical as transferred off site for disposal
while Facility B reports the same chemical as disposed of on site. In processing the data,
the TRI Program recognizes that this is the same quantity of the chemical and includes it
only once in the total disposal or other releases value. The production-related waste value in
TRI, however, considers all instances where the waste is managed (first as a quantity sent
off site for disposal and next as a quantity disposed of on site), and reflects both the off-site
transfer and the on-site disposal.
