Foreword / 4

A vital prerequisite for this success now and in the future is having globally consistent requirements with respect to sustainability, environmental protection and conservation of resources. The frequently discussed effects of the EU global emissions trading regime have led to increasing bias in international competition and called into question the long-term viability of the primary industry and, consequently, the downstream industry in Europe. A new and more contemporary awareness of the sustainability of steel as a working material must be created on a European level in order to counter this deve-lopment more forcefully than before. Steel must be discussed more comprehensively in order to emphasize its key role in achieving common environmental and energy-related objectives.

This updated Environmental Report and the consolidated version of the previous year are significant parts of our corporate environmental management program. The report focuses on the provisions of the EMAS III directive and offers objective and extensive insights into the multi-facetted activities and measures implemented at voestalpine.

The current economical and ecological facts and figures are satisfying and make us confident about our future. However, our full commitment to the achievement of our ob-jectives and the improvement of our current positions continues as we endeavor to stay true to our mission of remaining one step ahead.

All emission sources are continuously monitored. The data are referenced each individual calendar year.1) Hot­dip galvanizing line V and block 07 were put into operation during the 2010 calendar year.2) Reduction based on conversion to low­NOX burners (August 2010).3) The limit value is defined in the course of the hot­rolling­mill acceptance test.4) Unit deviates from other values in kg/h.5) There is also a fraction limit value of 150 kg SO2/day under normal operating conditions.6) H2S is contained in the coke oven gas that is energetically utilized in other process steps. Emissions only occur as SO2.

Linz is one of the cleanest industrial cities in Europe of today and is at the top of the list of 53 large cities in Europe with respect to air quality.*) voestalpine has contributed substantially to this development. Over the past 25 years (1985–2010) and in spite of a production increase of more than 60%, dust emissions have been reduced by more than 95%, SO2 emissions by more than 70% and NOX emissions by more than 25%.

Emissions during lime production at the Steyrling site are low and comply with the limit values. Many times, the figures fall well under the prescribed values. Diffuse emissions in mining are relevant and will be greatly reduced by the planned modernizations in mining. Weather conditions are taken into account during activities (such as blasting) that involve large quantities of dust.

The improved economic situation improved our production utilization during the 2010 calendar year and led to better overall energy efficiency than in previous years in most production units.

Among other things, this was due to great efforts in the following areas:

§ Systemic inspection of gas and thermal networks and resulting optimizations in plant configurations and energy-efficient production technologies

§ Measures to increase energy efficiency in pumps, electric motors and heating systems, reduction of energy consumption during downtimes and measures taken as part of the continuous improvement process. § Modernization and further expansion of plant systems

13 / Das QSU-Management13 / Water supply and treatment systems

Water is one of the most important (auxiliary) utilities throughout the entire production process. In order to conserve resources and minimize additional water consumption, process water is recycled wherever possible and is cleaned before it is released back into the environment. Depending on the elements contained in the waste water, it is either piped to the regional waste-water treatment plant of Linz AG or channeled into either the Danube or the Traun river.

The methods and process technologies used by voestalpine to treat waste water comply in every case with the pertinent standards and guidelines with respect to limit values. Many times, the figures fall well under the prescribed values. The required plant configuration for such compliance meets the most modern technical specifications.

Water supply and treatment systems

The increase in absolute discharged water volumes was due to higher production levels. But the value specific to production, however, was lower.

The processes in the integrated metallurgical facility utilize a great deal of residual and waste ma-terials (e.g. filter dust from the dedusting systems) that can be recycled to a high degree both inter-nally and externally in the metallurgical production plant systems and downstream units. Attempts are made continually to optimize the processes and procedures in order to utilize resources more efficiently and to attain a higher degree of material recycling. For example, iron-containing residu-als are efficiently recycled, particularly in the sintering plant, which is equipped with an efficient downstream waste gas cleaning system. In addition, residual materials occurring in both in-house processes and external waste are charged to the blast furnace to increase resource efficiency and to conserve natural raw materials.

Approximately 67.2% of the residual and waste materials at voestalpine were returned to the produc-tion processes during the 2010 calendar year. However, some hazardous and non-hazardous wastes that cannot be utilized in company operations are accumulated. These are dumped either at the internal deposits (5.9% during the 2010 calendar year) or are treated externally (26.9% during the 2010 calendar year). In the 2010 calendar year, approximately 18.9% of the non-hazardous and hazardous waste materials disposed of at external partners were recovered. The most voluminous waste material is dust generated in the dedusting systems during steel production. This dust weighed a total of 88,000 tons in the 2010 calendar year and is used in iron and zinc recycling processes. The degree of mate-rial recycling of residual and waste materials at the Linz site is 86.1%, which represents a substantial contribution to resource efficiency. In addition, the scrap produced in the works is used together with purchased scrap in the production of crude steel.

The following is a summary of the 2010 calendar year:

15 / Das QSU-Management15 / transportation

In addition to direct environmental effects at the Linz site that are thoroughly documented in this Environmental Report, transport is without a doubt the factor that contributes most to the indirect environmental impact.

Defining such diffuse emissions is difficult to impossible because of the large number of transport routes in use by the various means of transportation (railway, ship, truck) with a wide variety of engine and vehicle technologies.

For this reason, no direct emission assessment is made for the delivery of raw materials to the plant and for the dispatch of products from the plant. Only indirect but significant evaluation criteria are determined. As documented in literature, railway transport is the most environmentally sound with respect to emissions. This means of transport is followed by ship and then truck transportation.

The transport of raw materials is coordinated for the most part by voestalpine Rohstoffbeschaffung. The received raw material volumes in tons were multiplied by the number of kilometers transported and classified under the respective forms of transport.

The raw materials were distributed almost evenly in 2010, as in the 2009 calendar year, between ship and railway transports. There has, however, been a slight increase in raw material transport by railway. The raw material volumes delivered by truck remain insignificantly small (< 0.1%).

Product dispatch

Products are dispatched from the voestalpine site in Linz primarily through Logistik Service GmbH. Products manufactured by voestalpine are transported from Linz by rail, truck and ship to numerous customers worldwide. Product transports have been increasingly moved to the railway over the past few years. In the 2010 calendar year, the portion of dispatches to the railway system was increased to almost two thirds. This conforms to our view that rail transports are the most ecologically sound.

In spite of high customer demands with respect to delivery deadlines, more customers received on-time railway or combined (truck-rail-truck) deliveries than ever before. Successful implemen-tation of such measures and the accompanying stepwise transition from the truck to the railway are expected to reach their highest levels in the future.

17 / Das QSU-Management17 / Radiation, noise, odor and vibration

All raw materials at the site are inspected thoroughly for radiation by highly sensitive devices before they are delivered to production facilities. Radioactive tests are conducted on all heats of the interme-diate hot-metal product to rule out any risk. voestalpine customers are thus guaranteed a clean high-quality product.

In the course of the environmental impact assessment as part of the L6 Project, contingencies were made for noise emissions throughout the voestalpine works premises. The works premises were divided into 16 contingency sections. Higher noise loads of individual surface areas can be balan-ced by surface areas that do not reach permissible noise levels. The defined upper limits of noise pollution are in the interest of both our neighbors as well as those who work at voestalpine. From the perspective of neighborhood protection, limitation of noise emissions is important regardless of on-site expansion. The limit was defined in the interest of emission neutrality, which ensures that neighbors are not subjected to any additional perceivable noise pollution.

Many measures to prevent unpleasant odors have been successful in recent years. The most effective measures in this respect have been in the coking plant. The shutdown of the slag foaming plant was also an important measure, and the modernizations made in the coke oven batteries contributed greatly to the reduction of odors.

Lime-containing rock at the Steyrling site is mined from the walls of an open pit by means of conventional blasting. This can cause ground vibration. Shooting and blasting activities are announced to neighboring parties ahead of time.

Das QSU-Management / 18 Information for the public pursuant to Industrial Accident Act (IUV) / 18

Information to the public on safety measures and correct

behavior in the event of industrial accidents pursuant to

Section 13 of the Industrial Accident Act (IUV)

Your safety is our priority!

At the Linz production site, voestalpine Stahl GmbH operates plant systems that are subject to the Industrial Accident Act and provides the following information on safety measures and correct be-havior in the event of industrial accidents. Not every plant system failure is an industrial accident. An industrial accident is defined as an event in which certain dangerous substances are released that pose a danger to humans or to the environment. The precautions to be taken to prevent and limit industrial accidents are set forth in the Industrial Accident Act. Because of the comprehen-sive safety measures that have been taken for many years in production, the probability of you as a neighbor being affected by an industrial accident is very low. An industrial accident can only occur in the event that all the precautionary technical and organizational measures simultaneously fail. In the unlikely event that an industrial accident occurs in spite of all the safety measures that have been implemented, the following information advises you of steps to take.

There are four relevant plant areas in the integrated metallurgical facility that could have an effect beyond the works premises in the unlikely event of an industrial accident.

� Coke oven batteries, including coking gas recovery, conveyor system and gasometer. � Tar extraction and crude benzene plant, including storage tank � Blast furnaces, including furnace gas cleaning, conveyor system and gasometer � Converter operations, including converter gas cleaning, conveyor system and gasometer

Steam reformers A and B and air separation units 8 through 10 are operated according to the Linde low-pressure technology by Linde Gas GmbH and are safety-relevant systems installed on the works premises in Linz. The possible effects of this plant system are taken into account in this information. The substances contained in the systems of voestalpine Stahl GmbH and Linde Gas GmbH are subject to the provisions set forth in Section 8a of the Trade and Industrial Code dated 1994. The authorities have been notified pursuant to Section 84c, Para. 2 of the Trade and Industrial Code dated 1994.

Respective safety reports have been submitted to the authorities.

The following safety aspects are taken into account in the safety report submitted:

� Processes and reactions occur safely in closed systems. � Dangerous substances are replaced where possible and remaining amounts are reduced to

the specifically required volumes. � The avoidance of waste takes high priority in the planning and operation of plants. � Safety systems generally consist of multiple stages. � The plants are operated, maintained and tested by qualified personnel

regularly re-trained. � The plants are regularly tested in accordance with legal regulations by

in-house and external experts (such as TÜV).

19 / Das QSU-Management19 / Information for the public pursuant to Industrial Accident Act (IUV)

Stringent safety regulations are assessed by the authorities for all designated plant systems. As a result of these regulations and precautions taken by the operators, there has never been an accident at the works since it was established that would have posed any hazard to the population.

In spite of the high safety standards, the risk of accidents can never be completely eliminated. Even though the probability of an accident with effects beyond the works premises is very low, voestal-pine Stahl GmbH nevertheless takes this opportunity to inform the public in a precautionary man-ner of possible effects and measures to take in the event of an accident.

Coke oven batteries, including coke oven gas recovery, conveyor system and gasometerThe coke required in the blast furnace is produced in the coking plant. For this purpose, finely ground coal is heated in coking ovens that are arranged in batteries each containing a total of 40 ovens. The coal is heated for approximately 18 hours to a temperature of roughly 1,250°C. The coal is converted into coke, which means that it is baked until it has released all its gaseous constituen-ts. These gaseous constituents make up the coke oven gas that is cleaned to a high degree in the coking plant and is then used as a fuel gas in the power plant and other furnace systems throughout the steel works. A gasometer and a network of gas lines store the gas until it is used. Coke oven gas contains approximately 7% carbon monoxide and is, as are all flammable gases, combustible with certain amounts of air.

Tar extraction and crude benzene plant, including storage tankCrude tar and crude benzene occur as co-products during the high-grade cleaning of the coke gas. Crude benzene is cleaned out of the coke gas by means of wash oil in two scrubbers. It is then re-moved by means of distillation from the circulating wash oil and stored intermediately in a 2,000 m3 tank before it is delivered to purchasers. The crude benzene storage tank is suctioned out. The fil-ling process is by means of a gas displacement device to ensure that no emissions can be released. Crude benzene contains up to 85% benzene. The fumes are, as with all other flammable liquids, combustible when mixed with a certain amount of air. The crude tar condenses with condensati-on from the crude coke gas and is separated from the condensate in tar separators. Crude tar is pumped through the intermediate tar containers into the crude tar tanks. The individual parts of the tar separator units are equipped with a liquid-tight bucket system to prevent any emission to the environment. The crude tar and crude benzene are contained in tank railcars until they are used in the closed systems of production lines.

Blast furnaces, including blast furnace gas cleaning, conveyor system and gasometerBlast furnace gas is a by-product and co-product that occurs during the production of hot metal in the blast furnace. The technical term is top gas. This top gas is cleaned to a high degree, removing all the dusts, and is used as a fuel gas in the blast furnace itself, the power plant, in the coking plant and other furnace systems throughout the steel works. A gasometer and a network of gas lines store the gas until it is used. The entire network is a closed system. Top gas contains approximately 25% carbon monoxide and is, as are all flammable gases, combustible with certain amounts of air.

Converter operations, including converter gas cleaning, conveyor system and gasometerSteel differs chemically from iron primarily in its lower carbon content. The carbon contained in the crude iron produced in the blast furnace is removed from the steel melt by means of the oxygen top-blowing process during steelmaking in the LD steel plant. This process yields the so-called con-verter gas that is subjected to a high-grade cleaning process in electric filters and then added in a controlled manner to the top gas in order to increase its calorific value. A gasometer and a network of gas lines store the gas until it is used. The system of course is closed. Converter gas contains approximately 60% carbon monoxide and is, as are all flammable gases, combustible with certain amounts of air.

Das QSU-Management / 20 Information for the public pursuant to Industrial Accident Act (IUV) / 20

Air separation unitAir is divided in air separation units (8 through 10) belonging to Linde Gas GmbH by means of rectification into nitrogen, oxygen and argon constituents. The generated gases are either piped in gaseous form to consumers in the works of voestalpine Stahl GmbH or to the Chemiepark or they are liquefied, stored at super-cooled temperatures and filled into tank cars. In addition to the air as a raw material and different energies, hydrogen is also required in the argon fine cleaning system (8) of the air separation unit. This hydrogen is supplied by the hydrogen production facility at voestalpine.

Hydrogen production facilityNatural gas is converted through chemical reactions into hydrogen in the steam reformers (STR A and B) of Linde Gas GmbH. The gaseous hydrogen is supplied to voestalpine Stahl GmbH and Chemiepark in Linz. External customer supply is provided on trailer units.

Information on the types of dangers and theirpossible consequences

A high standard of safety is guaranteed through continuous monitoring by plant personnel, regular tests and the safety precautions described above.

Should an industrial accident occur, however, in spite of all the technical and organizational prepa-ration made to prevent such an incident, the emission of poisonous substances still poses a possible danger in addition to explosion and fire. In such an instance, effects on human health and the natu-ral environment outside the works premises, especially caused by gas or fumes that may be carried over distances, cannot be ruled out.

The following substances when emitted into the atmosphere pose a potential danger beyond the premises of the steel works.

Carbon monoxideCarbon monoxide is contained in:

� Coke oven gas (approx. 7 volume percent CO) � Blast furnace gas (approx. 25 volume percent CO) � Converter gas (approx. 60 volume percent CO)

The listed process gases are easily combustible and are poisonous because of their CO content. When emitted into the atmosphere, these gases are diluted with atmospheric air to differing degrees that lead to various symptoms depending on the respective concentrations. These symptoms may include headaches, dizziness, sickness, sleepiness, asphyxiation, unconsciousness and respiratory paralysis.

Patients must be exposed to fresh air, must rest comfortably and tight clothing must be loosened. In the event of apnea, mouth-to-mouth resuscitation is required to introduce oxygen to the brain. Call a doctor. Keep patients warm. If there is a risk of unconsciousness, place the patient on his or her side and transport in stable position.

BenzenePatients must be exposed to fresh air, must rest comfortably and tight clothing must be loosened. Resuscitate immediately in the event of apnea. Remove contaminated clothing immediately. Rinse contaminated skin sufficiently with water. Rinse contaminated eyes adequately with water for ten to fifteen minutes. Call a doctor. Keep patients warm. If there is a risk of unconsciousness, place the patient on his or her side and transport in stable position.

Atmospheric gases and hydrogenBecause of their volumes and properties (both not poisonous) and distances to other substances, the hazardous substances (oxygen, nitrogen, argon and hydrogen) contained in the air separation and hydrogen production units are not potentially dangerous outside the premises of voestalpine Stahl GmbH.
