                                     THE 33(50 PROGRAM
    This Company Profile is part of a series of reports being developed by EFA to highlight the accomplish-
ments of companies participating in the 33/50 Program.  The 33/50 Program is an EPA voluntary pollution
reduction initiative that promotes reductions in direct environmental releases and offsite transfers of 17 high-
priority toxic chemicals.  The program derives its name from its overall goals -an interim goal of a 33%
reduction by 1992 and an ultimate goal of a 50% reduction by 1995.  The program uses 1988 Toxics Release
Inventory (TRI) reporting as a baseline.  In February, 1991, EPA began contacting the parent companies of
TRI facilities that reported using 33/50 Program chemicals since 1988 to request their participation in the 33/50
Program. As of April, 1994, a total of 1,216
companies had elected to participate in the
Program, pledging to reduce emissions of the 17
target chemicals by more than 355 million
pounds by 1995.  Companies are encouraged to
set their own reduction  targets, which may vary
from the Program's national 33% and 50%
reduction goals.  Company commitments and
reduction pledges continue to be received by
EPA on a daily basis.

    The 1992 TRI data revealed that releases
and transfers of 33/50 Program chemicals de-
clined by 40% between 1988 and 1992, surpass-
ing the Program's 1992 interim reduction goal
by more than 100 million pounds.  This accom-
plishment,  together with evidence from analysis
of facilities' projected releases and transfers of
the 17 priority chemicals,  reported to TRI under
the Pollution Prevention Act, offers strong en-
couragement that the 33/50 Program's ultimate
goal of a 50% reduction by 1995 will be
achieved.

    EPA is committed to recognizing compa-
nies for their participation in the 33/50 Program
and for the emissions reductions they achieve. The Program issues periodic Progress Reports, in which
participating companies are listed and highlighted.  In addition, Company Profiles, such as this one, are being
prepared to provide more detailed information about companies that have written to EPA describing significant
emissions reduction initiatives.  Information presented in these profiles is drawn primarily from the company's
written 33/50 Program communications and the annual TRI reports submitted by their facilities (including
Pollution Prevention Act data reported to TRI in Section 8 of Form R).  All company communications to EPA
regarding the 33/50 Program are available to the public upon request.

33/50 Program Company Profile:  U.S. Steel Group

-------
                                    U.S.  Steel Group
    U.S. Steel Group reduced  total releases and
transfers of 33/50 Program chemicals by approxi-
mately 6,495,951  pounds from 1988 to 1992.  This
represents a reduction of 87%, significantly better-
ing its goal of a 30% reduction by 1992. U.S. Steel
is continuing its efforts toward achieving an inter-
nal corporate goal of a 90%  reduction in  all
environmental emissions, effluents, and wastes by
the year 2000.

      I. CORPORATE BACKGROUND

    The U.S. Steel Group  is a large, integrated
steel manufacturer and also includes several small-
er diversified  businesses. USX Corporation, U.S.
Steel's parent company, also is involved in the oil
and natural gas businesses through its Marathon
Oil Group and Delhi Group.  U.S. Steel has its
headquarters   in   Pittsburg,  Pennsylvania,   and
operates   six  wholly-owned  plants that  report
releases and  transfers of 33/50 chemicals.   In
addition, U.S. Steel is involved in  several joint
ventures  including  USS/POSCO  Industries  and
USS/Kobe Steel.  The joint venture facilities report
releases and transfers of 33/50 chemicals separate-
ly.

    Four of U.S. Steel's six facilities are in Penn-
sylvania:  The Clairton Works (Clairton), and  the
Edgar Thomson  (Braddock), Irvin (West Miffin),
and  Fairless  (Forest  Hills) plants  of  the  Mon
Valley Works.   The other  plants are  the Gary
(Indiana)  Works and the Fairfield (Birmingham,
Alabama) Works. A seventh facility, South Works,
in Chicago, Illinois, reported use of 33/50 chemi-
cals  until  manufacturing operation ceased at  the
facility in April  1992.  The facility therefore no
longer reports to the TRI.
Although  U.S. Steel set an initial goal
of reducing releases and transfers of
33/50 chemicals by only 30%, it was
successful in achieving a  reduction of
more than 87% by 1992.
    U.S. Steel's six facilities  report releases and
 transfers of eight 33/50 Program chemicals: ben-
 zene, chromium compounds, cyanide compounds,
 lead compounds, nickel compounds, toluene, 1,1,1-
 trichloroethane, and xylene. The primary source of

releases and transfers for each of these chemical
varies.

    Benzene, cyanide,  toluene,  and  xylene  are
released during the production of coke.  In  this
process, coal is heated in the absence of oxygen in
a series of ovens to drive off the volatile constitu-
ents in the coal including benzene,  cyanide, tolu-
ene, and xylene. The coke is then used as a reduc-
tant in blast furnaces.

    In the electric furnace operations at the former
South Works, dusts containing compounds such as
chromium, lead, nickel, and zinc  are produced in
the  melting of scrap to  produce carbon steels.
1,1,1-Trichloroethane was primarily used as a sol-
vent for cleaning equipment.

    Table I, at the end of this profile, presents the
company's  data on releases and transfers of  TRI
chemicals for the company, while Table II provides
these data for selected facilities. U.S. Steel report-
ed  a total  of 7,503,172 pounds  of releases  and
transfers of 33/50 Program chemicals in 1988. Its
Clairton  and Gary facilities were responsible for
97% of all  releases and transfers  in that year.

    II. CORPORATE ENVIRONMENTAL
                 STRATEGY

    In 1991, U.S. Steel's corporate environmental
affairs unit set up two complementary programs to
engage all members of its workforce in identifying
pollution prevention opportunities.

    The first of these, known as the Source Waste
Elimination  Environmental  Program (SWEEP),
focuses on identifying innovative process modifica-
tions to achieve source reductions.  Each facility is
encouraged to develop its own program for source
reduction by setting up SWEEP committees with
broad representation, including both management
and workers.  In 1991, the SWEEP program set a
goal of a 90% reduction in all environmental emis-
sions, effluents, and wastes  regulated under  the
Superfund Amendments and Reauthorization Act
(i.e., not just TRI  chemicals) by the year 2000.

    The  company's  second program  focuses on
environmental  training and  is known as  the Con-
tinuous Improvements to the Environment (CITE)
Program.  The program, which consists of two
tiers,  trains facility  workers  in  environmental
management.  The course content  in  tier one
focuses on environmental laws and regulations and
the impact of poor performance on the community,
the work place, and employees. In  tier two, work-
ers and  managers learn more detail about  the
specific manufacturing process at their facility and
their relationship  to specific job duties and envi-
ronmental  practices.   The  CITE  Program  has
helped to encourage more preventive maintenance
at the facilities, resulting in reductions in emis-
sions.  In 1991, U.S. Steel received the Optimus
Award from the Personnel Journal for its vision in
establishing the CITE employee training program.

    III. 33/50 PROGRAM GOALS AND
   POLLUTION REDUCTION ACTIVITIES

    In 1991, U.S. Steel committed to reduce its
total  releases  and  transfers of 33/50  Program
chemicals by 30%  from 1988 to 1992. Although it
was working toward a 50% reduction by  1995, the
company was  unable  to commit to a specific
reduction goal because  of  unpredictability of
production  levels.

    U.S.  Steel expected to achieve its reductions
through material reuse/recycling, process modifica-
tions, and product changes. - Based on its reported
1988 TRI data, the company's goal translates into
an overall reduction of 2,250,922 pounds in total
releases and transfers.

    U.S. Steel achieved significant reductions in
releases and transfers of 33/50 Program chemicals
through source reduction and recycling initiatives
at several  of  its  facilities.  Examples of specific
changes implemented by the company include:   •

•   Installation   of  inert   gas   blanketing
    systems.  These systems use nitrogen to con-
    fine air emissions  of volatile  toxic chemicals
    such as benzene, cyanide, toluene, and xylene.
    By maintaining  a  layer of inert  gas over an
    open tank or container, toxic chemical vapors
    are unable to escape from the tank.  U.S. Steel
    has installed blanketing systems on product
    and by-product storage tanks and decanters at
    both its Gary and Clairton plants.
U.S.  Steel has initiated two complimen-
tary company-wide programs to engage
all members of its workforce in the
search for pollution prevention oppor-
tunities.
    Implementation  of   dust   pelletizing
    process.   In the  steel-making operations,
    pollution control dusts containing iron units
    and various metallic compounds (e.g.,  chro-
    mium and lead) are produced.  Under normal
    circumstances,  these dusts  are landfilled.
    Because of the recoverable iron units in the
    dusts, the Edgar Thomson plant, U.S. Steel
    Mon Valley  Works has implemented a pel-
    letizing operation.  The  pellets are recycled
    back into the steel making operations.

    Modification   of  coke   quenching  pro-
    cess.  After the coke is removed from the
    Coke Ovens, it must be cooled rapidly. Pre-
    viously, the Clairton Works used contaminated
    water to quench the coke. Use of contaminat-
    ed water, however, resulted in releases of 33/50
    Program chemicals such as benzene and tolu-
    ene.  The facility switched to clean quench
    water 100% of the time, thus eliminating the
    releases of benzene and toluene  from the
    quenching operations.   The contaminated

   water is currently treated at the facility's waste
   water treatment plant where contaminants are
   removed to permitted levels.

     IV. PROGRESS TOWARDS 33/50
            REDUCTION GOALS

   As a result of these and a  variety of other
projects and initiatives, U.S. Steel has surpassed its
33/50 Program goal of a 30% reduction in releases
and transfers by 1992.   The company successfully
reduced its overall releases and transfers of 33/50
Program chemicals by 6,495,951 pounds, amount-
ing to a reduction of 87% from 1988 levels. In
addition, although  not an explicit part of  U.S.
Steel's goals, the company reduced annual releases
and transfers of non-33/50 TRI chemicals by  over
12.5  million pounds from 20,148,876 pounds for a
reduction of 63% since 1988.

   Overall,  U.S.  Steel has  reduced  its  annual
releases and transfers  of all  TRI chemicals  by a
remarkable 19,135,349  pounds since 1988.  This
represents a 69% reduction in  all releases and
transfers.
Overall,  U.S. Steel has reduced its re-
leases and transfers of 33/50 Program
chemicals by approximately 6,500,000
pounds since 1988, a reduction of 87%.
    U.S. Steel projects additional reductions in
releases and transfers of 33/50 Program chemicals
by 1994 (see Table III).  In addition, opportunities
identified  through the company's SWEEP  and
CITE programs are expected to continue to result
in further reductions of releases and transfers well
beyond  1994.

     V. SUMMARY OF U.S. STEEL'S
                EXPERIENCE

    By actively challenging all of its  plants to
identify opportunities to reduce emissions, wastes,
and effluents through company pollution preven-
tion programs, U.S. Steel has achieved significant
reductions in releases and transfers of 33/50 Pro-
gram  chemicals  at  each  of its  plants.    The
company's 87% reduction to date has far surpassed
its  goal of a 30% reduction in  33/50 Program
chemicals by 1992.
