Chapter 1 Overview on the Project

1.1 Background & Purpose of the Project

□A project to construct an industrial complex in Songsan

○ It is aimed to make the best use of the potentiality of Dangjin-gun as an industrial complex and to meet the increasing demand of developing the industrial complex in connection with the neighboring iron-steel companies and the existing factories of Hyundai Steel Company.

○With a continuous development in domestic construction and automobile industry, the demand industries resulting from the economic growth, it is necessary to solve the problem in securing materials caused by an imbalance of supply and demand, especially of hot-rolled and cold-rolled products.

○ It is to develop a steel industry belt which connects the Bugok·Godae District in the Asan National Industrial Complex to the existing factories of Hyundai Steel. By building a cooperative relation among relevant industries, the foundation of regional economy will be strengthened and it will be the basis for the regional development.

○Without using fossil fuels, the high pressure gas generated from the steel manufacturing process will operate a turbine producing the power. This power generation equipment will allow us to secure the basis for supply and demand of the environmentally-friendly energy. (A discussion on the environmental impact assessment of the energy facility has been done.)

○ It is intended to develop an environmentally-friendly industrial complex harmonized in terms of development and preservation so that the traffic condition of the industrial site gradually improves and the environmentally-sound, sustainable development of the region is promoted.

○ Furthermore, it improves the connectivity to and efficiency of the existing factories and at the same time, it copes with the constant increase in domestic demand for steel/iron materials. Also, the infra industry, the steel and iron industry in the northeastern region of Chungcheongnam-do (Province) is expanded and maintained in order to contribute to the development of national economy and regional society.

1.2 Reasons for Changing the Project Plan (Expansion of Blast Furnace No.3)

□ This project plans the Songsan Industrial Complex to develop the steel and iron industry in Gagok-ri and Donggok-ri, Songak-myeon, Dangjin-gun, Chungcheongnam-do. The following changes occurred resulting in an additional installation of Blast Furnace (originally Blast Furnace No.1 & No.2 → Blast Furnace No.1, No.2 & No.3) and an expansion of relevant production facilities.

□ Reasons for the Project Plan Changes① Dramatic Increase in the Mid/Long-Term Supply & Demand of Steel/Iron

- 4 -

○ The economies of China, India, Middle East and Southeast Asian countries have increased

○ Increase in the import of flat steels: The dependence of domestic market on China has increased, which may sharply increase the average unit price

○Prospect of the Global Steel/Iron Supply & Demand: 1200 million ton in 2008 → 1790 million ton in 2020

○Prospect of the Domestic Steel/Iron Supply & Demand: Shortage of 300 thousand tons of hot-rolled coils in 2015; Shortage of 480 thousand tons of thick plates in 2020

② Necessity to Increase the Number of Domestic Steel Mills

○ Expected that the demand for steel will increase compared to its supply due to the domestic economic recovery

○ Concerned about the shift from the resource nationalism to the material nationalism and creating the added value of sub-processes

○Due to the restructuring of steel and iron industry in China, it is estimated that 125 million tons of production capacity will decrease in 2011

○ Additional overseas factories of the domestic automobile industry and it is expected that the export market expands owing to the dramatic increase in demand for steel from the southeast asian countries

③ Effects of Hyundai Steel Blast Furnace Expansion (Additional No.3)

○With the construction of No.3, the size expands resulting in a stabilization of competitive market structure

○ Due to the vertical integration of Hyundai Automobile Group, the synergy effect generated, improving the productivity and developing technologies

○With an investment on No.3 in advance, it contributes to the national economic growth○Constructing an environmentally-friendly steel mill by developing a low-carbon, green-growth

technology○ Effects of Construction: Production inducement of 24.3 trillion won, creation of added value

15.3 trillion won and employment of 17.2 thousand people○ Effects of Operation: Production Inducement of 16.6 trillion won, creation of added value 10.4

trillion won and employment of 11.7 thousand people □ Thus, this project plan is changed to install one more Blast Furnace (total of 3 mills) and to

construct the relevant production facilities, increasing the crude steel production in the Songsan Industrial Complex so as to actively cope with the overseas steel demand and to alleviate the shortage of domestic steel supply. Moreover, the land use plan and some production facilities are altered to develop the industrial complex that complies with the relevant laws and regulations and that suits the conditions to create an efficient industrial complex and to enhance a reasonable factory management.

1.3 Details of the Project Implementation

○ After "the appointment of Songsan Industrial Complex district" in January, 2006, the environmental impact assessment was discussed on October 20th, 2006 for "the Project on Songsan Industrial Complex Construction". Since the project plans were changed, relevant members discussed the environmental impact assessment again on June 30th, 2008.

○ In addition, a facility to reduce air pollutants for each process in the industrial complex and a method to

treat waste gas were changed to complete the review on environmental preservation (first review). In July 2009, "The Second Review on the Environmental Preservation in the Songsan Industrial Complex" was carried out to include the some land of the "Project on Constructing a Steel Complex in the Naedo District"(B Hot-Rolled Product Factory, 1,079,749 ㎡), the land of the “Project on Building Unloading Yard for the Hyundai Steel Dangjin Plant"(49,318㎡) and the land of the “Project on Constructing a Private Thermal Power Plant at the Dangjin Plant of Hanbo Steel Industry Co., Ltd., Reclamation of the Public Water Surface including ash ponds & Construction of the Port”(342,788㎡). The inclusion of these lands to the Project did not increase the pollutants. In October 2009, "Changes to the Songsan Industrial Complex & Changes in the Implementation Plan" was approved.

B. Environmental Impact Analysis based on the Project Plan Changes

○ The project district is completed with a grading work that includes the cutting and banking, which requires a great deal of equipments and there is no earth work that changes the topography due to the changes to this project plan. The post environmental impact analysis was conducted for the project district and the neighboring areas of the project district under operation or construction, which satisfied the environmental quality standards. It is determined that there is a minor impact owing to the fugitive dust.

○ Therefore, the following environmental impact analyses were performed in relevance to the additional installation of the blast furnace no.1 and relevant manufacturing facilities, including the calculation of the air quality pollutants generated and the prediction of the air quality(air quality modeling).

(1) Under operation

(A) Air Pollutants Generated from the Industrial Complex○ Since the project plan on this industrial complex changed, an additional blast furnace and relevant

manufacturing facilities are planned. It is expected that the air pollutants will be generated owing to the operation of waste treatment facilities and the heating by the support facilities and the pollutants emitted from the factory and entering/exiting vehicles to/from the industrial complex, which are the same as the original re-agreement on the environmental impact assessment(2008.06), if the industrial complex is to be operated.

○ Meanwhile, it is analyzed that there is no change to the amount of pollutants generated from heating.

1) Items for Prediction of the Air Pollutants○ The items for forecasting the air pollutants generated from the industrial complex are the same

as those of the original plan(environmental impact assessment(re-agreement, 2008. 04)) and shown in .

2) Calculating the Amount of Pollutants Generated

A) Pollutants Generated during the Manufacturing Process

① Pollutants Generated during the Manufacturing Process

○ The project changes include an additional blast furnace and construction of relevant facilities.

- 29 -

The manufacturing process is the same as the original plan(Environmental Impact Assessment(re-agreement, 2008.04) as shown in , which is safe to say that the pollutants generated at each manufacturing facility when such industrial complex is under operation are the same, but the amount of air pollutants are different.

○ Furthermore, the amount of air pollutants was originally calculated by applying the basic unit, yet as the project plan changed, such amount was calculated assuming that the additional blast furnace is 100% under operation based on the self-measurement result of its test operation(2009.12~2010.03) that lasted 4 months.

Manufacturing Process

Ⓐ Sintering Plant○ The iron ore with a small grain size is sintered in the sintering factory so that it can be used at the

blast furnace. While processing the raw material, dust is generated and during coke combustion and material sintering, pollutants including dust, SOx, NOx and Dioxin are emitted. Also, when the sintered ore is extracted going through cooling, transporting, sorting and crushing processes, dust will be generated.

Ⓑ Limestone Calcination Factory○ The limestone and dolomite use the Coke Oven Gas in the limestone calcination factory to perform

calcination and it is a process to make a burned limestone to be used during the steel-making and a light burned dolomite used during the sintering. The burned limestone has the role to remove S and to control alkalinity during the steel-making process.

○ During the limestone calcination process, dust is generated during the transporting, sorting and crushing of raw materials and products as well as at the line and container. When the limestone and dolomite are calcinated at the furnace, pollutants including dust, SOx and NOx are emitted.

Ⓒ Cokes Factory○ This factory manufactures cokes by conducting a dry distillation of coals. The cokes are the essential

reducing agent as well as the energy source to manufacture pure iron by reducing the iron ore(Fe2O3, Fe3O4) at the blast furnace and act as the filler to form a blowhole that enables the gas to flow freely.

○ The dust is generated at the cokes factory when the raw material, coals are crushed, mixed, transferred and stored, when the dry-distilled cokes are transferred to the chemical conversion equipment and when the cokes are crushed, sorted and stored. Also, the pollutants including the dust, SOx and NOx

are emitted during the material combustion, when the coal is charged in the coke oven, during the coal dry-distillation, at the COG generated from the coke oven and the chemical conversion equipment.

Ⓓ Chemical Conversion Factory○ The by-product gas generated at the Coke Oven consists of dust, tar, benzene, H2S, NH3 and

macromolecular hydrocarbon. This is used as the main energy source in the steel mill, or sold by going through the process of separation and rectification after it is carried into the chemical conversion factory.

○ Some air pollutants are generated during the COG purification process. As the storage tank is sealed and the COG leakage is prevented by pump sealing and the purified COG is used as the fuel for each factory, it restrained the pollutants from being emitted.

○ The tail gas(N2, H2) that is generated the same as the assessment is planned to be circulated by the gas cooler shear, and the heating furnace type used to heat the absorption oil flowed into the BTX Still is converted from COG combustion type to Steam heating type to get rid of the pollutant source, which in result prevents the pollutants from being generated using the stack.

Ⓔ Blast Furnace Factory○ The Blast Furnace produces pig irons through a high-temperature reaction of sintered ore, cokes and

limestone, and pollutants including dust, SOx, NOx, Pb and bad smell are generated during the raw material handling process, the dust coal grinding and the slag cooling.

Ⓕ Steel-Making/Continuous Casting Factory○ The steel-making factory consists of 3 processes including the pre-treatment process, the conversion

process and the secondary refining process. The continuous casting factory includes a continuous casting process of slab using the roll attached to the mold vibration and segment by cooling the liquid ingot steel coming out from the converter, the primary cooling at the mold and the secondary cooling at the segment.

○ The air pollutants generated from the steel-making factory can be classified into the exhaust gas(LDG) that is emitted during the transportation of additive materials, the pre-treatment process, the pig iron smelting at the converter, and the dust and heavy metals generated during the ingot steel processing and manufacturing processes. In case of the continuous casting factory, it is predicted that the dust and heavy metals are emitted at the casting-completed Tundish shop and when removing the defects on the slab surface.

Ⓖ Hot-Rolling/Plate Factory○ After the slab manufactured during the continuous casting process is uniformly heated, it is hot-rolled to

be manufactured into the hot-rolled coil and plate products. The heating furnace at the hot-rolling factory produces dust, SOx, NOx and so forth and the plate factory generates dust, SOx and NOx when the slab is heated and during the heat processing.

Ⓗ Hot-Rolling B Factory○ Hot-Rolling B Factory at the Naedo District is incorporated into the Songsan Industrial Complex to build

an efficient industrial complex and to promote a reasonable factory management based on the “Environmental Preservation Plan for the Environmental Impact Assessment of Songsan Industrial Complex Construction, 2009.06", which led to no changes to the amount of pollutants.

② Calculating the Amount of Pollutants Generated during the Manufacturing Process○ The amount of pollutants generated for each manufacturing facility when the industrial complex

is under operation was calculated assuming that the additional blast furnace is 100% under operation based on the self-measurement result of its test operation(2009.12~2010.03) that

was calculated assuming that the additional blast furnace is 100% under operation based on the self-measurement result of its test operation(2009.12~2010.03) that lasted 4 months.

○ Meanwhile, this project plan changes include an additional installation of blast furnace as well as relevant facilities, which increased the size to around 150% compared to the original one〔Environmental Impact Assessment(re-agreement), 2008. 04 & Environmental Preservation Plan, 2009. 06. It is expected that the air pollutants will increase to approximately 150% compared to the original and decision-made plans, yet the air pollutant reducing facility shall be operated and managed as efficiently as possible when the Blast Furnace is under operation so as to minimize the emission of such pollutants.

○ As demonstrated in , the amounts of air pollutants generated due to the project plan changes are compared with the ones of the original and decision-made plans, showing an increase of dust to 135.56%, sulfur oxides to 134.44%, nitrogen oxides to 123.63% and CO to 134.44%. This is below the estimated emission of 150% as the blast furnace and relevant facilities are to be newly installed.

(B) Plan to Install the Air Pollutant Prevention Facility for Each Manufacturing Facility

○ The fuels used from raw material processing to steel product manufacturing in the industrial complex include green fuels such as the by-product gases(COG, BFG, LDG) and LNG to minimize the air pollutants generated during the given process.

○ In addition, the particulate matters emitted at each manufacturing factory when producing the steel products, and the gaseous contaminants are to be reduced by closely examining the optimal technologies to prevent and control the air pollutants emitted at each process. It may be required to install the optimal prevention facility, improve processes, replace the fuels or the raw materials, which is expected to minimize the pollutants in order to build a more environmentally-friendly steel mill.

○ There are no changes to the reduction plans suggested in the original plan( Environmental Impact Assessment(re-agreement), 2008. 04 & Review on Environmental Preservation Plan, 2009. 06) for the air pollutants generated at each factory when this industrial complex is under operation. The increased manufacturing facilities are the same for this project so the reduction facility will remain the same.

1) Raw Material Processing Facility○ Without any changes to the original plan, the raw material processing facility will be equipped with

sealed equipments for unloading, sealed conveyor belts and filter dust collectors, which will reduce the amount of fugitive dust at the coastal steel mills with strong wind. The raw materials are stored in the sealed circular/linear storage houses for the first time world-wide to fundamentally prevent the loss of raw materials and the generation of fugitive dust.
