United States Environmental Protection Agency Office of Pollution Prevention and Toxics 7408 EPA 745-K-94-016 May 1994 EPA's 33/50 Program Company Profile U.S. Steel Group Printed on Recycled Paper ------- 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. 17 PRIORITY CHEMICALS TARGETED BY THE 33/50 PROGRAM BENZENE CADMIUM & COMPOUNDS CARBON TETRACHLORIDE CHLOROFORM CHROMIUM & COMPOUNDS CYANIDES DICHLOROMETHANE* LEAD & COMPOUNDS MERCURY & COMPOUNDS METHYL ETHYL KETONE METHYL 1SOBUTYL KETONE NICKEL & COMPOUNDS TETRACHLOROETHYLENE TOLUENE 1,1,1-TRICHLOROETHANE TRICHLOROETHYLENE XYLENES Also referred to as methylene chloride 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.

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.

NR = Not reported to TRI. 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. 33/50 Program Company Profile: U.S. Steel Group ------- 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 33/50 Program Company Profile: U.S. Steel Group ------- 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. U.S. Steel's Progress Towards Meeting 33/50 Goals 1988 1989 1990 1991 1992 33/60 Goal: 30% reduction In releases and transfers of 33/60 chemicals by 1992 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.
