33/50 Program: The Final Record
The 33/50 Program targeted 17 priority chemicals (Box 1) and set as its goal a 33% reduction in
releases and transfers of these chemicals by 1992 and a 50% reduction by 1995, measured against a
1988 baseline. The first of EPA's growing series of voluntary programs, its primary purpose was to
demonstrate whether voluntary partnerships could augment the Agency's traditional command-and-
control approach by bringing about targeted reductions more quickly than would regulations alone.
The program also sought to foster a pollution prevention ethic, encouraging companies to consider
and apply pollution prevention approaches to reducing their environmental releases rather than
traditional end-of-the-pipe methods for treating and disposing of chemicals in waste.
Key Findings
The 33/50 Program achieved its goal in 1994, one year ahead of schedule,
primarily through program participants' efforts.
Although the largest reductions in 33/50 Program chemicals reflected U.S.
action to phase out ozone-depleting chemicals under the Montreal Protocol,
facilities also reduced releases and transfers of the other 33/50 chemicals by
50% from 1988 to 1995.
Facilities reported more source reduction activity (pollution prevention) for
33/50 chemicals than for other TRI chemicals and this activity covered a greater
percentage of production-related waste for 33/50 chemicals than for other TRI
chemicals.
Reductions continued at a higher rate for 33/50 chemicals than for other TRI
chemicals in the year after the 33/50 Program ended.

a
Program Goals Met and Exceeded
The 33/50 Program met its ultimate goala 50%
reduction in releases and transfers of the 17
targeted chemicalsin 1994, one year early (see
Figure 1). The most recent data show a 1988
baseline total for the 17 chemicals of 1.496 billion
pounds of on-site releases and transfers off-site
to treatment and disposaland a 1994 total of
748 million pounds. In 1995, releases and
transfers of the 33/50 chemicals totaled 672
million pounds, and by 1996, releases and
transfers had dropped nearly 60% from the 1988
baseline, to 601 million pounds. (Box 2 explains
the data presented in this report.)
33/50 Program Releases and
Transfers: Overview
For the 17 targeted chemicals, on-site releases and
transfers off-site to treatment and disposal
decreased from 1.496 billion pounds in 1988 to
672 million pounds in 1995 and further to 601
million pounds in 1996, as shown in Table 1. Over
the five years that the 33/50 Program operated,
releases and transfers of the 17 targeted chemicals
reported to TRI decreased 47%. This is an average
percent decrease per year of more than 9% for
1990-1995, compared to less than 8% per year
for the two previous years (1988-1990) and nearly
11% for the year after (1995-1996).

Box 2. Measure of Progress: Releases and Transfers
The types of on-site environmental releases reported to TRI have not changed from the first reporting year
air emissions, surface water discharges, underground injection, and on-site releases to land. The types of off-
site transfers that must be reported, however, have expanded. In the early years of TRI, facilities reported off-
site transfers to treatment (by private facilities or by publicly owned treatment works, POTWs) and to disposal.
Although TRI later began collecting data on transfers off-site to recycling and to energy recovery, these were
not covered by the 33/50 Program. The 33/50 Program therefore measured its progress in reducing all release
types plus transfers to treatment, POTWs, and disposal, based on the original TRI reporting categories.
With publication of the 1996 TRI data, EPA revised its summary presentations to reflect more closely the
character of certain off-site transfer types, specifically transfers to disposal. Because off-site disposal also
results in environmental release of the chemical, EPA began categorizing these transfers as an off-site release.
Data tables in this report adhere to this scheme, presenting total on- and off-site releases (including transfers
to disposal as off-site releases) plus off-site transfers to treatment (including POTWs). "Releases and transfers"
in this report refers to these specific release and transfer categories.
Tables and figures in this report emphasize three time periods in the 33/50 Program's history: 1988-1990
captures information before the program began, 1990-1995 measures progress during the program's tenure,
1995-1996 tracks developments in the first year after the program ended. Some tables and figures compare
amounts reported for 33/50 chemicals to reporting for all other TRI chemicals. To control for changes in the
TRI chemical list over time, year-to-year comparisons of this type are based on a consistent list of chemicals
reported in all years 1988 to 1996. Because TRI facilities can correct or revise their reports at any time for any
year, summary data measuring the achievements of the 33/50 Program change somewhat from year to year.
Data in this report are from the 1996 TRI database, as summarized in 1996 Toxics Release Inventory: Public
Data Release, EPA 745-R-98-005, May 1998.

33/50 Program chemicals outpaced all other TRI
chemicals for reductions in releases and transfers
in all three time periods shown in Table 1 and
Figure 2. Before the program began, the per-
centage reduction in 33/50 chemicals (15%) was
already somewhat greater than the reduction in
other TRI chemicals (14%). During the years the
program operated, however, facilities reported
much greater percentage reductions in the targeted
chemicals (47%) than for the others (25%). An
even greater difference in percentage reductions
appeared in the year since the program's close, as
33/50 chemicals dropped nearly 11% compared
to almost no decrease in other TRI chemicals (a
0.04% reduction).
Company Participation
EPA devoted considerable outreach effort for the
33/50 Program, focused on facilities reporting to
TRI on any of the targeted chemicals from 1988
to 1994more than 20,000 facilities in all. Initial
communications were directed to the chief
executive officers of parent companies of these
facilities. In the spring and summer of 1991,
invitations to participate in the program went to
a total of 5,000 companies. Another 2,500 more
were invited to participate over the next three
years. (See Table 2.)
Nearly 1,300 companies (13% of all eligible
companies) responded with commitments to the
33/50 Program, and their facilities reported more
than 60% of the 1988 releases and transfers of
the 33/50 chemicals.
EPA concentrated much of its outreach on the "top
600" companiesthose with the greatest amounts
of releases and transfers. (As mailing lists
improved and companies merged, the number of
actual companies contacted was closer to 500 than
600, but the name for this group remained "Top
600.") These companies received the first
invitations to participate and were the focus of
greater follow-up from 33/50 Program head-
quarters and region staff. This concentration on
larger companies proved effective: 64% of these
companies participated in the Program, compared
to less than 14% of the smaller companies.
Reductions Pledged
EPA encouraged participants to set their own
reduction goals, oriented to their own time frames,
and most did so. Of the 1,294 companies
participating, 1,066 set measurable goals for
reducing their releases and transfers of the 17
targeted chemicals against the 1988 baseline.
These pledges totaled 370 million pounds,

representing a little less than half of their total
1988 releases and transfers of 778 million pounds.
(See Table 2 and Figure 3.)
Other participant companies developed goals tied
to changes in their production levels, chose
alternative baseline years, or set a reduction target
for all their TRI reporting without specifying goals
for the 33/50 chemicals. Some made general
commitments, without numerical goals. Some
companies took a pollution prevention approach,
pledging to reduce their use of the targeted
chemicals. These pledges did not always specify
targeted goals for reducing releases and transfers.
As a result, the 370 million pounds of pledged
reductions in releases and transfers represented a
lower bound on the reductions that companies
attempted under the 33/50 Program.
Participant Goals Met and Exceeded
Participants whose commitments could be
calculated against the 1988 baseline achieved 507
million pounds of reductions from 1988 to 1995.

This greatly exceeded the group's total pledges
(370 million pounds) and amounted to 65% of
the group's 1988 baseline amount (778 million
pounds)well beyond the 50% national target.
(See Table 3 and Figure 4.)
Companies for whom commitments could not be
calculated against a 1988 baseline achieved
another 90 million pounds of reductions, out of
156 million pounds reported for 1988. This group
achieved a 58% reduction from 1988 to 1995.
Altogether, program participants in the program
accomplished a 64% reduction from 1988 to 1995.
Facilities belonging to companies that did not
participate in the program also achieved reduc-
tions, totaling 227 million pounds from 1988 to
1995 or 40%.
Releases and Transfers
by Chemical
On-site releases and transfers off-site to treatment
and disposal that facilities reported to TRI for the
17 targeted chemicals for 1988, 1990, 1995, and
1996 appear in Table 4. For 1988 to 1995, the
largest percentage reduction88%was
reported for 1,1,1-trichloroethane, an ozone-
depleting chemical discussed in more detail
below. The largest absolute reduction199
million poundswas reported for toluene.
Toluene, the chemical with the largest releases
and transfers in 1988 (367 million pounds),
remained the top 33/50 chemical in 1995 (169
million pounds) and 1996 (150 million pounds).

j 33/50 Program: The Final Record
As illustrated in Figure 5, most of the chemicals
showed consistent downward trends. However,
reductions occurred at a different pace among the
various chemicals. Figure 6 illustrates percentage
changes for the 33/50 chemicals. Figure 6 also
makes clear the more consistent reductions among
organic chemicals on the 33/50 Program list, with
the notable exception of carbon tetrachloride, and
the more erratic results among inorganic
substances on the list.
Organics versus Inorganics
Organic chemicals on the 33/50 Program's target
list constituted the majority of the releases and
transfers reported, as shown in Figure 7. Facilities
also reported larger reductions by far for the
organic chemicals than for inorganics, as shown
in Figure 8. Releases and transfers of organic
chemicals declined throughout 1988-1996,
including a reduction of nearly 50% during 1990-
1995. For the inorganic compounds, however,
releases and transfers decreased 30% during 1990-
1995 and increased before and after that time
period. Because organic chemicals accounted for
such a large proportion of the total reporting of
33/50 chemicals, their large percentage reductions
determined the overall percentage reduction for
the 33/50 chemicals.
Ozone Depleters
Among the organic substances targeted by the
33/50 Program were two ozone-depleting
chemicals, carbon tetrachloride and 1,1,1-
trichloroethane (TCA). The Montreal Protocol,
opened for international signature in 1987 and
amended in 1990 and 1992, called for phasing
out the production and use of designated ozone-
depleting chemicals by January 1, 1996. Imple-
menting this agreement, the United States banned
production of carbon tetrachloride and TCA by
that deadline.
Carbon tetrachloride accounted for a relatively
small portion of total releases and transfers of
33/50 chemicals, and its releases and transfers also
declined substantially before the 33/50 Program
began (from 5.3 million pounds in 1988 to 2.9
million pounds in 1990, a 49% decrease). With
201 million pounds of releases and transfers in
1988, however, the chemical 1,1,1 -trichloroethane
(TCA) constituted a much larger portion of the
33/50 Program's baseline. Further, releases and
transfers of TCA) decreased only 9% from 1988
to 1990. (See Table 4 and Figure 6.)
From 201 million pounds in 1988, releases and
transfers of TCA dropped to less than 25 million
pounds in 1995 and under 10 million pounds in
1996. TCA accounted for one fifth of the overall
reduction in 33/50 chemicals for 1988-1996. As
noted, carbon tetrachloride was the one 33/50
organic chemical whose releases and transfers
increased in the latest year (from a little over 1
million pounds in 1995 to 2 million pounds in
1996).
As shown in Figure 9, the two ozone-depleters
posted the greatest percentage reductions in
releases and transfers of 33/50 Program chemicals
from 1990 to 1996. While other 33/50 Program
chemicals decreased 40% from 1990 to 1995 and
9% in 1996, releases and transfers of carbon
tetrachloride and TCA decreased 86% during the
33/50 Program years and 54% in the year after.
Even though the ozone depleters accounted for
such large reductions, the other 33/50 chemicals
did meet the 50% reduction goal based on the
1988 baseline, as shown in Figure 10.

33/50 Program: The Final Record
Releases and Transfers by Type
Air emissions accounted for the great maj ority of
releases and transfers of 33/50 chemicals and the
great majority of reductions, as illustrated in
Figure 11. From 1988 to 1996, total air emissions
of 33/50 chemicals declined from 1.114 billion
pounds to 407 million pounds. Fugitive air
emissions declined 53% during 1990-1995 and
point source air emissions decreased 47%, as
illustrated in Figure 12.
Surface water discharges and transfers to POTWs
also decreased by substantial percentages during
1990-1995. However, in 1996, surface water
discharges, on-site releases to land, and off-site
transfers to treatment increased. (Totals presented
in Table 4 also summarize the 33/50 data by
release and transfer type.)
Releases and Transfers by State
Thirty-four states met or exceeded the 33/50
Program's goal of a 50% reduction in releases and
transfers of the targeted chemicals by 1995 (see
Table 5). New Hampshire recorded the largest
percentage decrease87%. Five other states had
reductions of more than 75% (Connecticut,
Maine, New Jersey, New York, and Minnesota).
States with Largest Baseline Totals
Most of the states with the largest releases and
transfers in 1988 met or exceeded the 50% goal
(see Table 5). Ohio facilities reported releases and
transfers totaling 103 million pounds for the
33/50 chemicals in 1988 and reduced that total to
37 million in 1995, a 64% reduction. Ranking first
for releases and transfers of the 17 chemicals in
1988, Ohio ranked fifth in 1995 and again in 1996.
Ranking second for releases and transfers of
33/50 chemicals in 1988, Texas was one of the
few large states whose reductions did not reach
50%. Texas facilities reported 101 million pounds
in 1988 and 52 million pounds in 1995, a 48%
reduction. Texas ranked first for total releases and
transfers of 33/50 chemicals in 1995 and 1996.
Indiana ranked third in 1988 and second in 1995,
although releases and transfers reported of the
33/50 chemicals in that state decreased 51% from
93 million pounds to 46 million pounds. A
substantial decrease in 1996 (to 37 million
pounds) returned Indiana to third place.
States with Increases
Releases and transfers fluctuated from year to year
in the states with 1988-1995 increases (Idaho,
Montana, and Nevada), as shown in Table 5. In
Puerto Rico, however, releases and transfers
decreased from a peak in 1991, although the 198 8-
1995 period shows a net increase. In 1996, Puerto
Rico's releases and transfers fell below the
territory's 1988 level.
Participants' Reductions by State
In 42 states and territories, participation in the
33/50 Program covered 50% or more of the 1988
baseline releases and transfers; the national
average was nearly 63% (see Table 6). Participants
accounted for more than 50% of the 1988-1995
reductions in all but 13 states and territories.

Although the 33/50 Program measured only the original TRI release and transfer types, other TRI data collected
in more recent years offers an expanded view of facilities' handling of the 33/50 chemicals. The federal
Pollution Prevention Act of 1990 made mandatory the reporting of amounts of TRI chemicals: recycled on- or
off-site combusted for energy recovery on- or off-site treated on- or off-site released on-site or sent off-site for
disposal. Reporting of these data began with the 1991 reporting year. Taken together, these data are referred
to as production-related waste. (Facilities report separately any releases arising from one-time events such as
clean-up activities or accidents, referred to as non-production-related waste data.)
Each year, facilities report production-related waste data for the prior year and current year, along with
projections for the next two years. This report uses the current year data from TRI forms submitted for each
year from 1991 to 1996, along with the projected data for 1997 and 1998 from the 1996 reporting forms.

-------
33/50 Program: The Final Record
This diverging trend continued in 1996, and
facilities projected even greater disparity in their
expectations for managing smaller amounts of
33/50 chemicals and larger amounts of other TRI
chemicals in production-related waste in the near
future, as shown in Table 7 and Figure 13.
Production-related Waste
by Chemical
Despite the trend for 33/50 chemicals overall,
facilities reported increasing production-related
waste from 1991 to 1995 for half of these
chemicals. Tables 8 through 12 present
production-related waste data by waste manage-
ment method for each of the 33/50 Program
chemicals. Figure 14 illustrates total production-
related waste by chemical.
As with releases and transfers, the 33/50 chemical
with the largest production-related waste was
toluene, mostly recycled on site. Facilities
reported 1.341 billion pounds of production-
related waste for toluene in 1991, increasing to
1.702 billion pounds in 1995. The increase
continued in 1996, to 1.816 billion pounds, and
facilities projected a total of 1.838 billion pounds
in 1998. (See Table 12.)
This and other increases were offset by sizable
decreases from 1991 to 1995 in production-related
waste of a few 33/50 chemicals. The largest
reduction occurred in reporting for the ozone
depleter 1,1,1-trichloroethane (TCA), again
reflecting the influence of U.S. action to
implement the Montreal Protocol. Facilities
reported 324 million pounds of TCA in
production-related waste in 1991 (about 40% in
recycled on-site and about 40% released on- and
off-site). This total dropped to 94 million pounds

in 1995 and 53 million pounds in 1995. By 1998,
facilities expect to report 17 million pounds of
this chemical in production-related waste.
As shown in Figure 15, the 33/50 chemicals have
varied considerably in the rate and direction of
changes in production-related waste from 1991
through 1996 and projected to 1998. As with
releases and transfers, organic chemicals have
more consistently decreased in production-related
waste than the inorganics.

j 33/50 Program: The Final Record
Production-related Waste
by Management Method
From 1991 to 1995, facilities cut their releases
on- and off-site of 33/50 chemicals from 884
million pounds to 576 million pounds (see Table
11). This was the largest reduction (309 million
pounds) among the waste management options
comprised by production-related waste. Reducing
releases also represents the most environmentally
desirable option, as established in the waste
management hierarchy (Box 4).
Combustion of 33/50 chemicals for energy
recovery on- and off-site decreased by 114 million
pounds over the 1991-to-1995 period. Although
on-site recycling also decreased, this change was
more than offset by a substantial increase in
recycling off-site. Altogether, recycling of 33/50
chemicals increased by 65 million pounds from
1991 to 1995.
Facilities also reported larger amounts of
treatment of the 33/50 chemicals, an increase of
257 million pounds. Except for recycling, these
trends generally continued in 1996 and were
expected to extend through 1998, as seen in Tables
8 through 12.
Figure 16 illustrates these changes in absolute
terms, and Figure 17 illustrates the percentage
changes for 1991 through 1998 (projected).
The data suggest that facilities accomplished
reductions in releases largely by increasing their
use of treatment options and that they plan to
continue this pattern. Although treating toxic
chemicals in waste is preferable to releasing them
to the environment, treatment offers less potential
environmental benefit than recycling, energy
recovery, or prevention.
Source Reduction Activity
TRI facilities also indicate whether, during the
year, they engaged in source reduction activities
focused on the chemical they are reporting. Source
reduction activities reduce the amount of the
chemical entering the waste stream (before any
recycling, treatment, or disposal)that is, source
reduction reduces pollution by preventing it at the
Box 4. Waste Management Hierarchy
The federal Pollution Prevention Act of 1990 established source reductionpreventing the generation of
toxic chemicals in waste at their sourceas the preferred approach waste management. This national policy
also established a hierarchy of options for situations where source reduction is not feasible:
For waste that cannot be prevented, recycling is the preferred option.
Because combustion of waste for energy recovery shares some aspects with other approaches,
EPA added energy recovery to the hierarchy.
For waste that cannot be recycled or burned for energy recovery, the next preferred option is
treatment.
Release or disposal of the chemical is viewed as a last resort, to be employed only when
preferred methods cannot be implemented.

source. The 33/50 Program encouraged partici-
pants to apply pollution prevention approaches
to reducing their releases and transfers of the
targeted chemicals.
In 1991, the first year of the 33/50 Program, one-
third (33%) of all TRI forms for 33/50 chemicals
indicated that source reduction activities were
underway, compared to less than one-quarter
(22%) of forms reporting other TRI chemicals,
as shown in Table 13. By 1995 (and again in
1996), both percentages had declined, but 33/50
chemicals continued to demonstrate a consider-
able lead over other TRI chemicals for reporting
of source reduction activity. Figure 18 illustrates
this trend.

directed at 33/50 chemicals reported 2.516 billion
pounds of production-related waste in 1991
45% of all production-related waste of these
chemicals, as shown in Table 14. For other TRI
chemicals, forms indicating source reduction
activity accounted for 4.248 billion pounds of
production-related waste33% of all production-
related waste of these chemicals.
These amounts and percentages fluctuated
through 1996, as illustrated in Figure 19, but in
all years forms indicating source reduction activity
were associated with a larger percentage of the
production-related waste for 33/50 chemicals than
for non-33/50 TRI chemicals.
