2001 Toxics Release Inventory
Executive Summary
BACKGROUND
The Toxics Release Inventory (TRI) is a publicly
available database that contains information on
toxic chemical releases and other waste
management activities reported annually by certain
covered industries as well as by federal facilities.
This inventory was established under the
Emergency Planning and Community Right-to-
Know Act of 1986 (EPCRA). In 1990 the
information required to be reported to TRI was
expanded by the Pollution Prevention Act. There are
now nearly 650 toxic chemicals and toxic chemical
categories on the list of chemicals that must be
reported to EPA and the States under the
EPCRA/TRI Program.
A facility must report to TRI if it meets the
following three criteria:
• Is in the manufacturing sector or, beginning in
the 1998 reporting year, is one of the following
industry categories: metal mining, coal mining,
electrical utilities, chemical wholesale
distributors, petroleum terminals and bulk
storage facilities, Resource Conservation and
Recovery Act (RCRA) subtitle C hazardous
waste treatment and disposal facilities, and
solvent recovery services. Also, federal facilities
must report to TRI regardless of their industrial
classification;
• Has 10 or more full-time employee equivalents,
and
• For all but certain persistent bioaccumulative
toxic (PBT) chemicals, manufactures or
processes more than 25,000 pounds or otherwise
uses more than 10,000 pounds of any listed
chemical during the calendar year.
'Two of the chemicals were added to the Polycyclic Aromatic Compounds category.
For the 2000 reporting year, the last criterion was
changed for certain PBT chemicals. TRI was
expanded to include new PBT chemicals and
reporting thresholds were lowered for both the
newly-added PBT chemicals and certain PBT
chemicals already on the TRI list. In a rule (64 FR
58666) finalized on October 29, 1999, EPA added
six PBT chemicals and one PBT chemical
category.1 PBT chemicals persist and bioaccumulate
in the environment and they have the potential to
pose greater exposure to humans and the
environment over a longer period of time, making
even small quantities of these chemicals of concern.
Therefore, EPA established thresholds lower than
the 25,000 pounds and 10,000 pounds. For those
chemicals that are persistent and bioaccumulate, a
threshold of 100 pounds manufactured, processed or
otherwise used was established. For the subset of
PBT chemicals that are highly persistent and highly
bioaccumulative, a threshold of 10 pounds was
established. In addition, because dioxins are highly
persistent and highly bioaccumulative, but are
generally produced in extremely small amounts, the
threshold for dioxin and dioxin-like compounds was
set at 0.1 gram.
Reporting thresholds for lead and lead compounds
were lowered in a separate PBT chemical rule (66
FR 4500) finalized on January 17, 2001. The lower
reporting threshold and requirements for lead and
lead compounds became effective for the 2001
reporting year and apply to all lead and lead
compounds except for lead when it is contained in
stainless steel, brass, or bronze alloys.
2001 DATA RELEASE
The time period covered for the 2001 data release is
the reporting year 2001. A reporting year is the

same as a calendar year. The 2001 data were
submitted to EPA by July 1, 2002 and are the focus
of this report. The Public Data Release report is an
analysis of the 2001 TRI data and trends in the data
from 1988 to 2001.
For the 2000 reporting year, certain PBT chemicals
(see above) were added to the list of TRI chemicals.
Also, in October 1999, EPA added vanadium
compounds to the TRI list and changed the
reporting qualifier for vanadium (already on the list
of TRI chemicals) from "fume or dust" to "except
when contained in an alloy." Vanadium and
vanadium compounds have not been classified as
PBT chemicals. For the 2001 reporting year, the
thresholds for lead and lead compounds (except for
lead when it is contained in stainless steel, brass, or
bronze alloys) were lowered to 100 pounds.
The 1998-2001 data include reporting by the
manufacturing industries, metal mining, coal
mining, electrical utilities, hazardous waste
treatment and disposal facilities, solvent recovery
facilities, chemical wholesale distributors, and
petroleum bulk stations and terminals. The
manufacturing sector has been reporting since 1987,
federal facilities have been reporting since 1994,
and the other industry sectors have been reporting
since 1998. Analyses for this period also include
only those chemicals reportable since 1998 with the
same reporting threshold and same definition.
The analysis of trends in the TRI data from 1988 to
2001 includes only the manufacturing industries
and those listed chemicals that have been reportable
since 1988 with the same reporting threshold and
same definition.
Year-to-year comparisons are based on a consistent
set of chemicals and reporting industries to assure
that any changes in releases or other waste
management data do not simply reflect changes in
reporting requirements from year to year. Thus,
comparisons of 2001 data with prior years do not
include persistent bioaccumulative toxic chemicals
subject to the October 1999 PBT chemical rule and
the January 2001 lead rule, or vanadium and

On-site and Off-site Releases, 2001
In 2001, 24,896 facilities submitted 95,513 forms.
On- and off-site releases for all TRI facilities
totaled 6.16 billion pounds for 2001. (See Table ES-
1 and Figure ES-1.)
On-site releases totaled 5.58 billion pounds or 91
percent of total releases on- and off-site in 2001.
The largest type of on-site releases was on-site land
releases, totaling 3.46 billion pounds or 56 percent
of total releases on- and off-site. As shown in Table
ES-1, the largest type of on-site land releases was
other disposal (that is, on-site land releases other
than to landfills, land treatment, and surface
impoundments, and may include releases to waste
piles or from spills or leaks). Other disposal totaled
2.04 billion pounds or 33 percent of total releases in
2001.
On-site air emissions, the second largest type of
release, were 1.68 billion pounds or 27 percent of
total releases. On-site surface water discharges were
220.8 million pounds and accounted for almost 4
percent of total releases. On-site releases to

Note: On-site Releases are from Section 5 of Form R. Off-site Releases are from Section 6 (transfers off-site to disposal) of Form R. Off-site Releases include metals and
metal category compounds transferred off-site for solidification/stabilization and for wastewater treatment, including to POTWs. Off-site Releases do not include transfers to
disposal sent to other TRI facilities that reported the amount as an on-site release.
* Storage only (disposal code M10) indicates that the toxic chemical is sent off-site for storage because there is no known disposal method. Amounts reported as transferred
to storage only are included as a form of disposal (off-site release). See Box 1-5.
** Beginning in reporting year 1997, transfers to solidification/stabilization of metals and metal category compounds (waste treatment code M41) are reported separately from
transfers to solidification/stabilization of non-metal TRI chemicals (waste treatment code M40). Because this treatment method prepares a metal for disposal, but does not
destroy it, such transfers are included as a form of disposal (off-site release). See Box 1-6. Reports under code M40 of metals and metal category compounds have been
included in solidification/stabilization of metals and metal category compounds in this report.
*** Beginning in reporting year 1997, transfers to wastewater treatment (excluding POTWs) of metals and metal category compounds (waste treatment code M61) are
reported separately from transfers to wastewater treatment of non-metal TRI chemicals (waste treatment code M60). Because wastewater treatment does not destroy
metals, such transfers are included as a form of disposal (off-site release). See Box 1-6. Transfers of metals and metal category compounds reported under code M60 have
been included in transfers of metals and metal category compounds to wastewater treatment.
**** Reported as discharges to POTWs in Section 6.1 of Form R. EPA considers transfers of metals and metal category compounds to POTWs as an off-site release
because sewage treatment does not destroy the metal content of the waste material.
***** Unknown (disposal code M99) indicates that a facility is not aware of the type of waste management used for the toxic chemical that is sent off-site. Amounts reported
as unknown transfers are treated as a form of disposal (off-site release).

2001 Toxics Release Inventory Public Data Release
-------
2001 Toxics Release Inventory Executive Summary
underground injection wells totaled 215.4 million
pounds or 3.5 percent of total releases in 2001.
Releases also include transfers of TRI chemicals in
waste sent off-site for disposal to such sites as
landfills and underground injection wells. Off-site
releases (transfers off-site to disposal) were 577.7
million pounds or 9 percent of all releases in 2001.
Of these off-site releases 364.7 million pounds of
chemicals were sent off-site to landfills/surface
impoundments and 123.5 million pounds of metals
and metal category compounds were sent for
solidification/stabilization.
On- and Off-site Releases by State
Nevada, followed by Utah, Arizona, and Alaska,
were the four states with the largest total on- and
off-site releases. They each reported more than 500
million pounds in total releases for 2001. (See Table
ES-2.)
Facilities in Nevada reported total releases of 783.5
million pounds and those in Utah reported 767.2
million pounds. Nevada and Utah each accounted
for about 13 percent of all releases on- and off-site
in 2001. Arizona had 606.8 million pounds of
releases on- and off-site or 10 percent of the total
and Alaska had 522.1 million pounds, or 8.5
percent of the total for 2001. These four states each
had more than 95 percent of their total releases as
other on-site releases (that is, on-site land releases
to other than RCRA subtitle C landfills).
Texas had the fifth largest total releases on- and off-
site in 2001, with 270.5 million pounds or 4 percent
of total releases. Facilities in Texas reported the
largest on-site underground injection, with 77.6
million pounds or 40 percent of total on-site
underground injection in 2001, all of which went to
Class I wells. Texas also reported the largest surface
water discharges, with 26.0 million pounds or 12
percent of all such releases in 2001.
Ohio had the sixth largest total releases on- and off-
site, with 254.6 million pounds or 4 percent of the
total. Facilities in Ohio reported the largest air
emissions, with 121.3 million pounds or 7 percent
of all on-site air emissions in 2001. North Carolina
facilities reported the second largest air emissions,
with 115.1 million pounds or about 7 percent of
total air emissions.
After Ohio, Pennsylvania had the next largest total
releases on- and off-site (207.5 million pounds or 3
percent of the total). Facilities in Pennsylvania
reported the largest off-site releases (transfers off-
site to disposal) in 2001, with 88.2 million pounds
or 15 percent of total off-site releases in 2001.
On- and Off-site Releases by Industry
The metal mining industry reported the largest total
releases on- and off-site in 2001. The 2.78 billion
pounds of total releases in 2001 reported by metal
mining facilities accounted for 45 percent of all
releases on- and off-site in 2001. Most (over 99
percent) releases by the metal mining industry were
as other on-site land releases (that is, on-site land
releases to other than RCRA subtitle C landfills).
The 2.76 billion pounds of other on-site land
releases reported by the metal mining industry in
2001 represented 83 percent of all such releases.
(See Table ES-3.)
Electric utilities reported the second largest releases
on- and off-site in 2001, with 1.06 billion pounds or
17 percent of total releases. Over two-thirds of
releases by electric utilities were air emissions. The
717.6 million pounds of air releases from electric
utilities accounted for 43 percent of all air
emissions reported in 2001. Electric utilities
reported 266.7 million pounds of other on-site land
releases (other than to RCRA subtitle C landfills),
which made it the industry sector with the second
largest amount of such releases.
The chemical manufacturing industry reported
582.6 million pounds of releases on- and off-site in
2001, making it the industry sector with the third
largest releases. Total releases by the chemicals
industry accounted for 9.5 percent of total releases
from all sectors in 2001. Chemical manufacturers
reported the largest amount of on-site underground
injection, with 168.0 million pounds or 78 percent
of all such releases.

Note: On-site Releases are from Section 5 of Form R. Off-site Releases are from Section 6 (transfers off-site to disposal) of Form R. Off-site Releases include metals and
metal category compounds transferred off-site for solidification/stabilization and for wastewater treatment, including to POTWs. Off-site Releases do not include transfers to
disposal sent to other TRI facilities that reported the amount as an on-site release.
Facilities/forms are included in the manufacturing industry categories (SIC Codes 20-39) if they did not report a SIC code in the other industries. Forms that reported more
than one 2-digit SIC code within the range 20 to 39 are assigned to the "multiple codes" category. Facilities/forms are included in the other industry categories if the
facility/form has a SIC code in the other industries and no SIC code in 20-39. If the facility reported in any year prior to 1998 and the facility/form has a combination of
manufacturing and other industry SIC codes, then the facility/form is included in the manufacturing industry category. If the facility reported for the first time in 1998 or later
and the facility/form has a combination of manufacturing and other industry SIC codes, then the facility/form is included in the other industry category. Forms with no 2-digit
SIC code are included in the "no codes 20-39" category. One facility, Phelps Dodge Miami of Claypool, AZ, that reported under SIC code 33 and SIC code 10 in 2001 and
previous years has been included in SIC code 10 for the purpose of this analysis.

Note: On-site Releases are from Section 5 of Form R. Off-site Releases are from Section 6 (transfers off-site to disposal) of Form R. Off-site Releases include metals and
metal category compounds transferred off-site for solidification/stabilization and for wastewater treatment, including to POTWs. Off-site Releases do not include transfers to
disposal sent to other TRI facilities that reported the amount as an on-site release.
The primary metals industry reported the fourth
largest releases on- and off-site, with 558.6 million
pounds or 9 percent of total releases in 2001. The
primary metals industry had the largest off-site
releases (transfers off-site to disposal) of any
industry, with 271.8 million pounds accounting for
47 percent of all off-site releases in 2001.
On- and Off-site Releases by Chemical
Table ES-4 lists the 20 TRI chemicals with the
largest total releases in 2001. On- and off-site
releases of the top 20 TRI chemicals totaled 5.40
billion pounds, 88 percent of the total 6.16 billion
pounds of all TRI chemicals released on- and off-
site. Total on-site releases for these 20 TRI
chemicals totaled 4.93 billion pounds, representing
88 percent of all on-site releases. Off-site releases
(transfers off-site to disposal) constituted 464.6
million pounds or 80 percent of all off-site releases
in 2001.
Of the 5.40 billion pounds of total releases of the
top 20 TRI chemicals, 3.22 billion pounds or 60
percent were as other on-site land releases (that is,
on-site land releases to other than RCRA subtitle C
landfills). Another 25 percent (1.33 billion pounds)
were on-site air emissions. The distribution of
releases for the top 20 TRI chemicals differed
somewhat from that for all TRI chemicals, where 54
percent of total releases were other on-site land
releases and 27 percent were on-site air emissions.
Copper compounds constituted 17 percent (1.02
billion pounds) of the 6.16 billion pounds of total
on- and off-site releases for all TRI chemicals in
2001. Zinc compounds accounted for the second
largest releases, with 962.1 million pounds or 16
percent. Hydrochloric acid was the third-most
common chemical, constituting 10 percent (588.1
million pounds). Most of the releases of copper and
zinc compounds were as other on-site land releases
(that is, other than RCRA subtitle C landfills) while
most releases of hydrochloric acid were on-site air
emissions.

On- and Off-site Releases of PBT
Chemicals
PBT chemicals accounted for 454.4 million pounds
of total on- and off-site releases in 2001. (See Table
ES-5.) On-site land releases, totaling 386.9 million
pounds, were 85 percent of total releases of PBT
chemicals in 2001. Of the on-site land releases,
RCRA subtitle C landfills accounted for 21.1
million pounds, with other on-site land releases
totaling 365.8 million pounds. Off-site releases
(transfers off-site to disposal) were 57.8 million
pounds, representing 13 percent of the total releases
of PBT chemicals in 2001.
On-site underground injection of PBT chemicals in
2001 was 6.2 million pounds, total air emissions
were 3.0 million pounds, and surface water
discharges of PBT chemicals totaled less than
440,000 pounds.
Of the 454.4 million pounds of total on- and off-
site releases of PBT chemicals, lead and lead
compounds constituted 97 percent (443.0 million
pounds) of the total in 2001. On- and off-site
releases of mercury and mercury compounds
totaled 4.9 million pounds, polycyclic aromatic
compounds totaled 3.0 million pounds, and
polychlorinated biphenyls totaled 2.5 million
pounds.

Forms for the dioxin and dioxin-like compounds
category represented 8 percent (1,320 out of
15,794) of all the PBT chemicals forms for 2001.
Dioxin and dioxin-like compounds are reported in
grams and subject to a lower reporting threshold
(0.1 grams) than the other PBT chemicals. Almost
148,759 grams of total releases of dioxin and
dioxin-like compounds were reported for 2001.
Over 60 percent of total releases of dioxin and
dioxin-like compounds were released off-site as
transfers to disposal. Of the on-site releases, almost
three-quarters (74 percent) were other on-site land
releases, that is on-site land releases to other than
RCRA subtitle C landfills, such as other types of
landfills, surface impoundments, and land
treatment.
More detailed information on releases of PBT
chemicals, including dioxin and dioxin-like
compounds, can be found in Chapter 3 of this
report.
Waste Management Data, 2001
A total of 26.74 billion pounds of TRI chemicals in
production-related waste was reported as managed
during 2001. Almost 7.56 billion pounds of toxic
chemicals in production-related waste were recycled on-
site in 2001, representing 28 percent of all toxic
chemicals in production-related waste. (See Table ES-6.)
Another 6.93 billion pounds were treated on-site,
accounting for 26 percent of the toxic chemicals in
production-related waste managed in 2001. Almost
6.18 million pounds (23 percent) were released on-
and off-site. On-site energy recovery constituted
2.65 billion pounds or 10 percent while off-site
recycling was 1.97 billion pounds or 7 percent. Off-
site energy recovery and off-site treatment each
accounted for 3 percent or less of the total toxic
chemicals in production-related waste managed in
2001.
Quantities of TRI Chemicals in Waste
by State
Texas, followed by Louisiana and Illinois reported
the largest quantity of toxic chemicals in
production-related waste managed in 2001. With
more than 1.5 billion pounds each, these three states
accounted for 30 percent of all toxic chemicals in
production-related waste in 2001. (See Table ES-7.)
Texas reported the largest amount of toxic
chemicals in production-related waste, with 3.96
billion pounds or 15 percent of the total for 2001.
Texas also reported the largest amount of TRI
chemicals in waste treated on-site, with 1.75 billion
pounds or 25 percent of all on-site treatment in
2001. Facilities in Texas also reported the largest
amount of on-site energy recovery, with 875.9
million pounds or 33 percent of all TRI chemicals
in waste burned for energy recovery on-site.
Louisiana, with 2.3 billion pounds of toxic
chemicals in production-related waste, accounted
for 8 percent of the total. Facilities in Louisiana
reported the second largest amounts treated on-site
(1.09 billion pounds) and the second largest
amounts of on-site energy recovery (316.8 million
pounds).
Illinois was the state with the third largest quantity
of toxic chemicals in production-related waste, with
1.91 billion pounds or 7 percent of total toxic
chemicals in production-related waste in 2001.

Note: Data are from Section 8 of Form R.
Facilities/forms are included in the manufacturing industry categories (SIC Codes 20-39) if they did not report a SIC code in the other industries. Forms that reported more
than one 2-digit SIC code within the range 20 to 39 are assigned to the "multiple codes" category. Facilities/forms are included in the other industry categories if the
facility/form has a SIC code in the other industries and no SIC code in 20-39. If the facility reported in any year prior to 1998 and the facility/form has a combination of
manufacturing and other industry SIC codes, then the facility/form is included in the manufacturing industry category. If the facility reported for the first time in 1998 or later
and the facility/form has a combination of manufacturing and other industry SIC codes, then the facility/form is included in the other industry category. Forms with no 2-digit
SIC code are included in the "no codes 20-39" category. One facility, Phelps Dodge Miami of Claypool, AZ, that reported under SIC code 33 and SIC code 10 in 2001 and

-------
2001 Toxics Release Inventory Executive Summary
Over 1.23 billion pounds of lead and lead
compounds in production-related waste,
representing 96 percent of all production-related
waste of PBTs, was managed in 2001. There was 25
million pounds of polycyclic aromatic compounds
in production-related waste (2 percent of the total
for PBT chemicals). There was 6.7 million pounds
of hexachlorobenzene, 5.8 million pounds of
mercury and mercury compounds, 4.1 million
pounds of polychlorinated biphenyls and 2.7 million
pounds of pesticides managed in waste.
Dioxin and dioxin-like compounds in production-
related waste managed totaled almost 446,649
grams for 2001. Dioxin and dioxin-like compounds
are reported in grams and subject to a lower
reporting threshold (0.1 grams) than the other PBT
chemicals. Over half (52 percent or 234,296 grams)
of the dioxin and dioxin-like compounds in waste
were treated on-site with most of the remaining
released on- and off-site (154,421 grams).
More detailed information on PBT chemicals,
including dioxin and dioxin-like compounds, can be
found in Chapter 3 of this report.
Transfers for Further Waste
Management, including Disposal
A total of 4.08 billion pounds of TRI chemicals in
waste was transferred off-site for further waste
management, including disposal, in 2001. (See
Table ES-11.) Transfers off-site to recycling total
1.95 billion pounds or 48 percent of all transfers for
further waste management, including disposal.
Another 840.3 million pounds, accounting for 21
percent, were transfers to energy recovery.
Other off-site transfers to disposal were 664.3
million pounds or 16 percent of total transfers for
further waste management in 2001. Transfers to
POTWs were 339.9 million pounds or 8 percent of
the total, and transfers to treatment were 279.7
million pounds or 7 percent.
Projections of TRI Chemicals in
Waste and Source Reduction
TRI facilities expected to decrease their quantities
of toxic chemicals in production-related waste
managed between 2001 and 2003 by less than one
percent, from 25.50 billion pounds to 25.34 billion
pounds. The projected totals were 24.95 billion
pounds for 2002, a decrease of just over 2 percent
from 2001 to 2002 and 25.34 billion pounds for
2003, an increase of just under 2 percent from 2002
to 2003.2 (See Table ES-12.) The decrease was
projected to occur within on-site recycling, off-site
energy recovery, on-site treatment, and the quantity
released on- and off-site. On-site recycling, with
7.01 billion pounds in 2001, was expected to
decline by less than one percent by 2003. Off-site
energy recovery, with 826.3 million pounds in 2001,
was expected to decline by 5 percent by 2003. On-
site treatment, with 6.93 billion pounds in 2001,
was expected to decline by less than one percent.

Note: Does not include lead and lead compounds. Data from Section 8 of Form R for 2001.
Two facilities made errors in reporting the quantity released on- and off-site. One facility reported 6,500,022,100 pounds for 2000; the correct number is 65,000 pounds. One
facility reported 4,976,250,100 pounds for 2002; the correct number is 49,762 pounds. These corrections were received too late to be included in the publicly released
database, but they have been included in this table.
The quantity released on- and off-site was expected
to decline by 5 percent, from 5.75 billion pounds to
5.45 billion pounds. The quantity released on- and
off-site decreased by 5 percent from 2000 to 2001.
On- and off-site releases are the least-desirable
outcome under the waste management hierarchy
described in Waste Management in Chapter 1
(Figure 1-2).
Off-site recycling, on-site energy recovery and off-
site treatment were expected to increase from 2001
to 2003. Off-site recycling was projected to increase
by less than one percent, from 1.71 billion pounds
in 2001 to 1.72 billion pounds in 2003. Off-site
recycling decreased by 6 percent from 2000 to
2001. On-site energy recovery was projected to
increase by 9 percent from 2001 to 2003, from 2.65
billion pounds to 2.88 billion pounds. On-site
energy recovery decreased by 5 percent from 2000
to 2001. Off-site treatment was expected to increase
by 4 percent, from 625.3 million pounds to 648.5
million pounds. Off-site treatment increased by 5
percent from 2000 to 2001.
In 2001, 4,534 of the 22,359 TRI facilities submitting
a Form R reported undertaking one or more source
reduction activities. As noted in Waste Management
in Chapter 1, source reduction—an activity that
prevents the generation of waste—is preferred to
waste management. These 4,534 facilities represented
20.3 percent of the TRI facilities submitting a Form R
in 2001. (See Table ES-13.)

2001 Toxics Release Inventory Public Data Release
ES-15
-------
2001 Toxics Release Inventory Executive Summary
There were 18,340 forms with source reduction
activity reported in 2001, representing 22 percent of
all Form Rs in 2001. The most frequently reported
source reduction activity was good operating
practices (listed by 10 percent of the facilities).
Process modifications came next, reported by 7
percent of facilities, followed by raw materials
modifications (by 5 percent of facilities) and spill
and leak prevention (by 4 percent of facilities).
TRI DATA FOR 2000-2001
The data used to compare 2000 to 2001 do not
include lead and lead compounds since the
thresholds for reporting on lead and lead
compounds were lowered for 2001 to 100 pounds.
Total On-site and Off-site Releases,
2000-2001
All TRI Chemicals
From 2000 to 2001, total TRI releases on- and off-
site fell by 1.05 billion pounds or 15.5 percent. On-
site releases decreased by 1.08 billion pounds,
while off-site releases (transfers off-site to disposal)
increased by 32.7 million pounds. The number of
facilities and forms reporting each decreased by 4
percent. (See Table ES-14.)
On-site land releases comprised the largest type of
on-site release and had the largest absolute decrease
of 739.1 million pounds or 19 percent from 2000 to
2001. Disposal in RCRA subtitle C landfills
decreased by 83.6 million pounds or 41 percent,
while other on-site land releases decreased by 655.5
million pounds or 18 percent.
On-site air emissions, the second largest type of on-
site release, decreased by 237.1 million pounds or
12 percent from 2000 to 2001. Point source air
emissions decreased by 221.5 million pounds or 13
percent and fugitive air emissions decreased by 15.6
million pounds or 6 percent. Other types of on-site
releases include underground injection and surface
water discharges. Underground injection decreased
by 61.2 million pounds or 23 percent and surface
water discharges decreased by 46.9 million pounds
or 17.5 percent.
The increase in off-site releases (transfers off-site to
disposal) was primarily due to the increase of 30.2
million pounds (an increase of 41 percent) of metals
and metal category compounds sent for
solidification/stabilization and the increase of 21.8
million pounds (7 percent) in transfers to
landfills/surface impoundments. Transfers to land
treatment also increased from 2000 to 2001, by 1.5
million pounds or 25.5 percent.
Other types of off-site releases (transfers off-site to
disposal) decreased from 2000 to 2001. Off-site
underground injection decreased by 4.2 million
pounds or 20.5 percent and transfers to storage
decreased by 3.5 million pounds or 38 percent.
PBT Chemicals
On- and off-site releases of PBT chemicals
decreased from 11.6 million pounds to 11.4 million
pounds from 2000 to 2001, a decrease of almost 2
percent. Off-site releases decreased by 44 percent
(2.0 million pounds) while on-site releases
increased by 25 percent (1.8 million pounds). (See
Table ES-15.)
The decrease in off-site releases (transfers to
disposal) of PBT chemicals was largely due to a
decrease of transfers off-site to landfills/surface
impoundments of 1.6 million pounds (41 percent),
which included decreases of 1.4 million pounds of
polycyclic aromatic compounds.
On the other hand, the increase in on-site releases
of PBT chemicals was due to an increase in on-site
land releases of 2.2 million pounds. Such releases
of mercury and mercury compounds increased by
1.2 million pounds and by 1.1 million pounds for
polychlorinated biphenyls. Other types of on-site
releases showed decreases, including air emissions
which decreased by 355,196 pounds or 20 percent.
Total releases of dioxin and dioxin-like compounds
increased by 50 percent (by 49,714 grams) from
2000-2001. On-site releases increased by 30 percent
(by 9,476 grams) and off-site releases increased by
67 percent (by 36,548 grams). The largest increases
occurred in off-site transfers to landfills/surface

POTWs. Off-site Releases do not include transfers to disposal sent to other TRI facilities that reported the amount as an on-site release.
* Storage only (disposal code M10) indicates that the toxic chemical is sent off-site for storage because there is no known disposal method. Amounts reported as transferred
to storage only are included as a form of disposal (off-site release). See Box 1-5.
** Beginning in reporting year 1997, transfers to solidification/stabilization of metals and metal category compounds (waste treatment code M41) are reported separately from
transfers to solidification/stabilization of non-metal TRI chemicals (waste treatment code M40). Because this treatment method prepares a metal for disposal, but does not
destroy it, such transfers are included as a form of disposal (off-site release). See Box 1-6. Reports under code M40 of metals and metal category compounds have been
included in solidification/stabilization of metals and metal category compounds in this report.
*** Beginning in reporting year 1997, transfers to wastewater treatment (excluding POTWs) of metals and metal category compounds (waste treatment code M61) are
reported separately from transfers to wastewater treatment of non-metal TRI chemicals (waste treatment code M60). Because wastewater treatment does not destroy
metals, such transfers are included as a form of disposal (off-site release). See Box 1-6. Transfers of metals and metal category compounds reported under code M60 have
been included in transfers of metals and metal category compounds to wastewater treatment.
**** Reported as discharges to POTWs in Section 6.1 of Form R. EPA considers transfers of metals and metal category compounds to POTWs as an off-site release
because sewage treatment does not destroy the metal content of the waste material.
***** Unknown (disposal code M99) indicates that a facility is not aware of the type of waste management used for the toxic chemical that is sent off-site. Amounts reported

Waste Management, 2000-2001
Quantities of TRI Chemicals in Waste,
2000-2001
There was a decrease from 32.57 billion pounds in
2000 to 25.50 billion pounds in 2001 of toxic
chemicals managed in waste. This represented a
decrease of 22 percent or 7.07 billion pounds. (See
Table ES-16.)
On-site recycling, the largest type of waste
management in 2001, decreased by 8 percent or
577.5 million pounds. On-site treatment, the
second largest type of waste management,
decreased by 5.27 billion pounds or 43 percent,
from 12.20 billion pounds to 6.93 billion pounds.
The quantity released on- and off-site decreased by
882.4 million pounds (13 percent) from 6.63 billion
pounds to 5.75 billion pounds. On-site energy
recovery decreased from 2.78 billion pounds to
2.65 billion pounds, a 5 percent decrease. Off-site
recycling also decreased, from 1.93 billion pounds
to 1.71 billion pounds, an 11 percent decrease.

The quantity of toxic chemicals in non-production-
related waste, waste due to remedial clean-up
efforts or due to one-time catastrophic events, was
lower in 2001 than in 2000. In 2000 it was 246.4
million pounds and in 2001 it was 38.6 million
pounds.
Transfers Off-site for Further Waste
Management, including Disposal,
2000-2001
Transfers of toxic chemicals off-site for further
waste management, including disposal, decreased
by 133.9 million pounds or 3 percent from 2000 to
2001. In 2000, total transfers were 3.89 billion
pounds, and in 2001 they were 3.76 billion pounds.
(See Table ES-17.)
The decrease in total transfers off-site for further
waste management, including disposal, was
primarily due to the decrease in transfers to
recycling. Transfers to recycling decreased by 181.6
million pounds or 10 percent from 2000 to 2001.
Transfers to POTWs was the second largest
decrease of almost one million pounds or less than
one percent.
Other types of transfers increased from 2000 to
2001. Transfers to energy recovery represented the
largest increase, of 30.1 million pounds or 4
percent. Other off-site transfers to disposal
increased by 17.5 million pounds or 3 percent.
TRI DATA FOR 1998-2001
The data used to compare 1998-2001 do not include
the PBT chemicals or vanadium or vanadium
compounds since some PBT chemicals and
vanadium compounds were added to the TRI list of
chemicals in 2000 and the reporting definition for
vanadium changed. Also, the reporting thresholds
for all PBT chemicals changed.

-------
2001 Toxics Release Inventory Executive Summary
Total On-site and Off-site Releases,
1998-2001
Total on- and off-site releases of TRI chemicals
decreased by 22 percent from 1998 to 2001, a net
decrease of 1.58 billion pounds. On-site releases
decreased by 25 percent, but off-site releases
(transfers off-site to disposal) increased by 26
percent. The number of facilities and forms
reporting each decreased by 7 percent. (See Table
ES-18.)
All types of on-site releases decreased for the four-
year period 1998-2001. On-site land releases
decreased by 1.11 billion pounds or 27 percent,
with releases to RCRA subtitle C landfills
decreasing by 73.9 million pounds or 39 percent
and other on-site land releases by 1.03 billion
pounds or 26 percent. On-site land releases had
increased from 1998 to 1999 but then showed
decreases from 1999 to 2001. (See Table ES-18 and
Figure ES-2.)
Air emissions decreased steadily throughout the
period with an overall decrease of 23 percent (499.8
million pounds), with point source air emissions
decreasing by 19.5 percent (346.8 million pounds)
and fugitive air emissions decreasing by 39 percent
(152.9 million pounds). Underground injection also
decreased, by 19 percent (50.1 million pounds).
However, underground injection increased from
1999 to 2000 with decreases in the other years.
Surface water discharges decreased by 13.5 percent
(34.2 million pounds) overall from 1998 to 2001
with an increase from 1998 to 1999 and decreases
after that. (See Table ES-18 and Figure ES-2.)
On the other hand, total off-site releases (transfers
off-site to disposal) increased in all years from
1998 to 2001. The net increase in off-site releases
was 106.8 million pounds or 26 percent. Transfers
of metals and metal category compounds to
solidification/stabilization represented the largest
increase, of 61.9 million pounds or 149 percent.
Transfers to landfills/surface impoundments
represented the second largest increase of 51.2
million pounds (19 percent), followed by an
increase in transfers off-site to underground
injection of 7.8 million pounds (almost 94 percent).
Other increases in off-site transfers included
transfers to land treatment, which increased by 4.9
million pounds, and transfers of metals and metal
category compounds to wastewater treatment
facilities that are not POTWs, which increased by
almost one million pounds. (See Table ES-18 and

wastewater treatment, including to POTWs. Off-site Releases do not include transfers to disposal sent to other TRI facilities that reported the amount as an on-site release.
* Storage only (disposal code M10) indicates that the toxic chemical is sent off-site for storage because there is no known disposal method. Amounts reported as transferred

** Beginning in reporting year 1997, transfers to solidification/stabilization of metals and metal category compounds (waste treatment code M41) are reported separately from
transfers to solidification/stabilization of non-metal TRI chemicals (waste treatment code M40). Because this treatment method prepares a metal for disposal, but does not
destroy it, such transfers are included as a form of disposal (off-site release). See Box 1-6. Reports under code M40 of metals and metal category compounds have been
included in solidification/stabilization of metals and metal category compounds in this report.
*** Beginning in reporting year 1997, transfers to wastewater treatment (excluding POTWs) of metals and metal category compounds (waste treatment code M61) are
reported separately from transfers to wastewater treatment of non-metal TRI chemicals (waste treatment code M60). Because wastewater treatment does not destroy
metals, such transfers are included as a form of disposal (off-site release). See Box 1-6. Transfers of metals and metal category compounds reported under code M60 have
been included in transfers of metals and metal category compounds to wastewater treatment.
**** Reported as discharges to POTWs in Section 6.1 of Form R. EPA considers transfers of metals and metal category compounds to POTWs as an off-site release
because sewage treatment does not destroy the metal content of the waste material.

Waste Management Data,
1998-2001
Quantities of TRI Chemicals in Waste,
1998-2001
Overall, the quantities of TRI chemicals in waste by
all TRI industries decreased by 8 percent from 1998
to 2001, a net decrease of 2.18 billion pounds. The
quantity of toxic chemicals in production-related
waste managed decreased from 27.54 billion
pounds in 1998 to 25.36 billion pounds in 2001.
However, the total quantity of toxic chemicals in
production-related waste had increased from 1998
to 2000, by 4.88 billion pounds, followed by a
decrease of 7.06 billion pounds from 2000 to 2001.
(See Table ES-19 and Figure ES-3.)
Much of the decrease from 1998 to 2001 came in
the quantities released on- and off-site, which
decreased by 1.56 billion pounds or 22 percent.
Releases on- and off-site decreased steadily each
year from 1998 to 2001.
The quantities of toxic chemicals recycled,
combusted for energy recovery, and treated off-site
also decreased. The decrease in on-site recycling
was 381.1 million pounds or 5 percent. However,
on-site recycling showed decreases and increases in
alternating years throughout the 1998 to 2001

decrease from 2000 to 2001 of 13.4 million pounds.
(See Table ES-20 and Figure ES-4.)
Both transfers to recycling and transfers to energy
recovery decreased by over 70 million pounds from
1998 to 2001. Transfers to recycling decreased by
74.0 million pounds or 4 percent, from 1998 to
2001, but had increased from 1998 to 1999.
Transfers to energy recovery decreased by 70.0
million pounds or 8 percent from 1998 to 2001, but
showed increases from 1999 to 2001. Transfers to
treatment also decreased, by 48.0 million pounds or
15 percent, but showed increases in the most recent
period from 2000 to 2001. (See Table ES-20 and
Figure ES-4.)
Transfers to POTWs of metals and metal category
compounds decreased by 1.4 million pounds or 39
percent. However, transfers to POTWs of non-metal
TRI chemicals increased by 7.4 million pounds or 2
percent. Other types of transfers also increased
from 1998 to 2001. Other off-site transfers to
disposal increased by 77.9 million pounds or 15
percent, showing increases in each year from 1998
to 2001. (See Table ES-20 and Figure ES-4.)
TRI DATA FOR 1988-2001
Year-to-year comparisons of TRI data from 1988 to
2001 are based on a consistent set of chemicals and
reporting industries. They do not include chemicals
added or deleted since 1988; they do not include
chemicals such as the PBT chemicals whose
reporting threshold has changed; and they also do
not include the industries that were added to TRI
reporting in 1998.
Total On-site and Off-site Releases,
1988-2001
For the core set of chemicals from industries that
have reported consistently since 1988, total on- and
off-site releases decreased by 54.5 percent between
1988 and 2001, a reduction of 1.72 billion pounds.
At the same time, the number of forms submitted
also declined, by 9 percent. On-site releases
decreased by almost 64 percent or 1.76 billion
pounds. However, off-site releases increased over
this period by 12 percent or 46.7 million pounds.
(See Table ES-21 and Figure ES-5.)
All on-site release categories showed overall
decreases from 1998 to 2001. Air emissions have

Releases include metals and metal category compounds transferred off-site for solidification/stabilization and for wastewater treatment, including to POTWs. For the years
1998 and after, does not include industries, other than manufacturing industries, that are required to report for 1998 and later years only.
* Storage only (disposal code M10) indicates that the toxic chemical is sent off-site for storage because there is no known disposal method. Amounts reported as transferred
to storage only are included as a form of disposal (off-site release). See Box 1-5.
** Beginning in reporting year 1997, transfers to solidification/stabilization of metals and metal category compounds (waste treatment code M41) are reported separately from
transfers to solidification/stabilization of non-metal TRI chemicals (waste treatment code M40). Because this treatment method prepares a metal for disposal, but does not
destroy it, such transfers are included as a form of disposal (off-site release). See Box 1-6. Reports under code M40 of metals and metal category compounds have been
included in solidification/stabilization of metals and metal category compounds in this report.
*** Beginning in reporting year 1997, transfers to wastewater treatment (excluding POTWs) of metals and metal category compounds (waste treatment code M61) are
reported separately from transfers to wastewater treatment of non-metal TRI chemicals (waste treatment code M60). Because wastewater treatment does not destroy
metals, such transfers are included as a form of disposal (off-site release). See Box 1-6. Transfers of metals and metal category compounds reported under code M60 have
been included in transfers of metals and metal category compounds to wastewater treatment.
**** Reported as discharges to POTWs in Section 6.1 of Form R. EPA considers transfers of metals and metal category compounds to POTWs as an off-site release
because sewage treatment does not destroy the metal content of the waste material.
***** Unknown (disposal code M99) indicates that a facility is not aware of the type of waste management used for the toxic chemical that is sent off-site. Amounts reported
as unknown transfers are treated as a form of disposal (off-site release).
decreased steadily over the years 1988 to 2001,
with the exception of an increase from 1997 to
1998. Overall, on-site releases decreased 70 percent
or 1.53 billion pounds. Surface water discharges
decreased by 65 percent or 27.0 million pounds
from 1988 to 2001, however, that time period also
saw increases as well as decreases. Surface water
discharges have decreased since 1998. (See Table
ES-21 and Figure ES-5.)
On-site underground injection also had an overall
decrease of 41 percent or 67.0 million pounds from
1988 to 2001, with several periods of increases
within that time period. In the most recent years,
underground injection increased from 1999 to 2000
with a decrease reported from 2000 to 2001. On-
site land releases fell almost 38 percent or 142.4
million pounds. Increases in on-site land releases
were reported from 1994 to 1997, but decreases
have occurred each year from 1997 to 2001. (See
Table ES-21 and Figure ES-5.)
Off-site releases, with an overall increase of 12
percent from 1988 to 2001, have shown increases
2001 Toxics Release Inventory Public Data Release

-------
2001 Toxics Release Inventory Executive Summary
since 1992 with the exception of the period 1997 to
1998. The largest increases in off-site releases
(transfers off-site to disposal) occurred in
solidification/stabilization of metals and metal
category compounds, an increase of 130.3 million
pounds or over 489 percent, and in off-site
underground injection, an increase of 6.5 million
pounds or 76 percent. Transfers of metals and metal
category compounds to wastewater treatment
facilities that were not POTWs increased by 2.3
million pounds or 50 percent. (See Table ES-21 and
Figure ES-5.)
Other types of off-site releases (transfers to
disposal) decreased. The amount of chemicals in
waste sent to other off-site management decreased,
by 32.3 million pounds or 87 percent. Transfers to
waste brokers for disposal decreased by 19.9
million pounds or 70 percent. Disposal in
landfills/surface impoundments decreased by 10.7
million pounds or 4 percent.
UNDERSTANDING THE USES, SCOPE
AND LIMITS OF TRI DATA
While TRI provides the public, industry, and state
and local governments an invaluable source of key
environmental data, it has some limitations that
must be considered when using the data. Although
the Agency has expanded the number of industries
that must report, the program does not cover all
sources of releases and other waste management
activities of TRI chemicals. Although TRI is
successful in capturing information on a significant
portion of toxic chemicals currently being used by
covered industry sectors, it does not cover all toxic
chemicals or all industry sectors. In addition,
facilities that do not meet the TRI threshold levels
(those with fewer than 10 full-time employees or
those not meeting TRI reporting quantity
thresholds) are not required to report. Thus, while
the TRI includes 95,513 reports from 24,896
facilities for 2001, the 6.16 billion pounds of on-
and off-site releases reported represent only a
portion of all toxic chemical releases nationwide.
In addition, while many facilities base their TRI
data on monitoring data, others report estimated
data to TRI as the program does not mandate
release monitoring. Various estimation techniques
are used when monitoring data are not available,
and EPA has published estimation guidance for the
regulated community. Variations between facilities
can result from the use of different estimation
methodologies.
TRI reports reflect releases and other waste
management activities of chemicals, not exposures
of the public to those chemicals. Release estimates
alone are not sufficient to determine exposure or to
calculate potential adverse effects on human health
and the environment. Although additional
information is necessary to assess exposure and
risk, TRI data can be used to identify areas of
potential concern.
TRI data, in conjunction with other information,
can be used as a starting point in evaluating
exposures that may result from releases and other
waste management activities of toxic chemicals.
The determination of potential risk depends upon
many factors, including the toxicity of the chemical,
the fate of the chemical after it is released, the
locality of the release, and the populations that are
exposed to the chemical after its release.
ACCESSING THE TRI DATA
The TRI data and data release reports may be
accessed through the EPA's TRI home page at
http://www.epa.gov/tri. The TRI home page also
includes other background information on the TRI
program and TRI data as well as information on
applicable statutes, regulations and guidance.
