CHAPTER – I INTRODUCTION

1.1 PREAMBLE

India is on a threshold of a steel revolution. The National Steel Policy envisages production of 110 million ton per annum (MTPA) of steel in India by the year 2020.

This implies that the country, which produces 40 MTPA of steel currently, will have to add around 70 MTPA of new steel making capacity in the next 13 to 14 years. This translates into addition of more than 5 MTPA of steel making capacity every year till 2020. On a national level, a multi-pronged strategy has been formulated for attaining this goal. The demand for steel will increase through rapid infrastructural development and a quantum increase in rural steel consumption. Keeping pace with the demand, domestic steel production will be enhanced through creation of additional capacity. The expansion plans of existing steel producers and entry of new players are all indicative of a very bright future for steel industry. The National Steel Policy has set a long-term goal that India should have a modern and efficient steel industry of world standards, catering to diversified steel demand. The focus of the policy is to achieve global competitiveness not only in terms of cost, quality and product-mix but also in terms of global benchmarks of efficiency and productivity.

In view of the above M/s N.R. Ispat & Power Private Limited has proposed to establish an Integrated Steel Plant to produce steel and also products that aid in making steel.

1.2 PURPOSE OF THE REPORT

As per the Ministry of Environment & Forests, New Delhi notification, dated 14th September, 2006 all Primary metallurgical processing industries are classified under Category ‘A’.

In order to obtain Environmental Clearance for the proposed Integrated Steel plant Form -I, proposed draft TOR along with Pre-Feasibility Report were submitted to the Honourable Ministry. A presentation was made before the Expert Appraisal Committee of MOEF on 11th June, 2008 for the approval of TOR for EIA study. The Draft EIA report has been prepared in accordance with the Terms of Reference (TOR) issued by the Ministry vide letter no. J-11011/225/2008-IA II (I) dated 3rd July, 2008.

This report furnishes the details of location of Site, Description of the project, prevailing baseline status w.r.t Air Environment, Water Environment, Noise Environment; land Environment, Flora & Fauna and Socio-economic environment.

This report also helps in identification of environmental impacts and suggesting mitigation measures to be followed during Construction and Operation of the project as a part of Environmental Management Plan. This report also acts as guidance manual for the proponent for following the Environmental Management Plan (EMP) and for adopting post project Environmental Monitoring Program as per statutory norms.

1.3 IDENTIFICATION OF PROJECT & PROJECT PROPONENT

M/s N.R. Ispat & Power Private Limited (NRIPL) has been promoted by well established entrepreneur belongs to Raigarh in Chhattisgarh state and already established in the field of manufacturing and trading of Finished/ semi finished Steels at Village: Gourmudi, Tehsil: Tamnar, District Raigarh (C.G.).

(3)

NRIPL already purchased land admeasures about 53 acres, which is quite sufficient for the installation.

M/s NRIPL propose to generate Power by installing 1 x 10 MW FBC based and also install 2 x 2 MW WHRB based power plant aggregating generation capacity to 14 MW for captive consumption only.

To meet the annual coal requirement for Sponge iron manufacturing as well as Power generation will be meet through either Captive mining or Long term Coal Linkage with South Eastern Coalfields Ltd. (SECL) mines.

The project cost estimate for installation of the proposed plant works out to Rs. 95.00 Crores. This is inclusive of equipment cost as erected including civil and structural works, taxes & duties and contingencies. It is proposed to achieve synchronization and commercial operation within 24 months, which is to be reckoned from the date of financial closure.

Financial analysis has been carried out for the project considering that the fund requirement will be met on a debt equity ratio of 63:37.

The following is the list of some of the important people in the organization:

i. Shri Sanjay Kumar Agrawal ii. Shri Rajesh Kumar Agrawal Name of Directors :

iii. Shri Vijay Kumar Agrawal

Steel being a basic commodity for all industrial activities, quantum of its consumption is considered an index of industrial prosperity. Since independence, there has been a substantial growth in the steel sector in India from 1.5 Million Tons in 1950-51 to about 31 Million Tons at present. Additional steelmaking capacity of about 8 to 10 Million Tons /year exists in the secondary steel sector.

(4)

Despite the above growth in the steel sector, the per capita steel consumption continues to remain at a level of about 27 kg only, compared to about 350 to 450 kg in the developed countries and 40 to 100 kg in some of the developing countries.

Further, with nearly 20% of the world population, India’s contribution is only of the order of 3.4% of world steel production. Hence, short-term and long-term strategies are necessary in planning the development of the steel industry in the country to improve the level of per capita steel consumption.

It is expected that with the measures taken by Govt. of India for promotion consumption of iron and steel and expected growth of Indian economy the requirement of steel will significantly increase and accordingly the domestic manufacturing capacity needs to be increase.

Considering the potential of iron and steel in India and the experience gained by the group in this sector, M/s N.R. Ispat & Power Private Limited (NRIPL) propose to install the following units at Village: Gourmudi, Near Gerwani, Tehsil: Tamnar District: Raigarh in the state of Chhattisgarh.

1.4.4 IMPORTANCE OF PROJECT

Steel has been regarded as the most useful product for mankind. It reaches every home, and has a wide range of applications from a small pin to the manufacture of automobiles, building of the railway systems, ships, big construction projects, housing, oil rigs, nuclear power stations an so on. Steel is also eco-friendly.

Steel products are categorised into broad segments : Non-flat (popularly known as Long products) and Flat products. Finished steel Non-flat products include rounds, bars including re-enforcement bars, wire rods, structural such as angles, channels, joist / beams and railway materials in the shape of rails, wheels and axles. All these products play a key role in the growth of a country's more important sectors like construction, power, oil and gas, engineering, railway and road transportation, port, irrigation etc.

INDIAN STEEL SCENARIO

Indian steel industry is undergoing a period of restructuring, improving its ranking among global steel producers from the 9th place to the 7th place. In the last 5 years, the production and consumption of steel has grown at exceeding rates of 9% per annum. The pace of growth has further accelerated in the current year to over 10%.

As per the latest CRISIL report a stable trend in the domestic steel industry’s operating margin in 2007-08 as compared with that of 2006-07, is predicted. The firm steel prices will keep the rise in input cost under check. The global demand-capacity ratio, which figured at around 89 percent in 2006, is expected to remain the same during 2007, which will maintain the similar price range as registered in the preceding year. Domestic prices are expected to follow the international prices trend.

The CRISIL report also predicts buoyancy in the domestic steel demand. With healthy activity in pipes and tubes, automobiles and the construction segment, the

(9)

growth in demand for flat products with 11 percent to 21 Mn Tons during 2007-08, where as demand for long products is expected to grow by 7.6 percent to 19 Mn Tons.

The Eleventh Five Year Plan projects a 9% average annual growth in our GDP.

Higher expectations to see a massive increase in investment in infrastructure is probable. Consequently, massive growth in demand for steel in the next few decades is also credible – perhaps to levels never visualized before.

BENEFIT TO THE REGION

With the establishment of the proposed plant, there will be a lot of employment opportunities to the local people during construction and operation of the plant.

During construction it creates employment to about 350 persons and during operation it creates employment to about 100 persons. Priority will be given to locals in employment. There will be upliftment of the socio-economic status of the people in the area due to the proposed project.

In the light of the above scenario, M/s. N.R. Ispat & Power Private Limited has proposed to establish an Integrated steel plant in Village: Gourmudi, Near Tamnar, Tehsil: Tamnar District: Raigarh, Chhattisgarh.

1.5. SCOPE OF THE STUDY

The scope of work includes a detailed characterization of the environment in an area of 10 km. radius of the plant for various environmental parameters like air, water, noise, land, biological and social-economic aspects and preparation of Draft EIA report incorporating all TOR issued by MOEF.

2.2 NEED FOR THE PROJECT

Indian steel industry is undergoing a period of restructuring, improving its ranking among global steel producers from the 9th place to the 7th place. In the last 5 years, the production and consumption of steel has grown at exceeding rates of 9% per annum. The pace of growth has further accelerated in the current year to over 10%.

As per the latest CRISIL report a stable trend in the domestic steel industry’s operating margin in 2007-08 as compared with that of 2006-07, is predicted. The firm steel prices will keep the rise in input cost under check. The global demand-capacity ratio, which figured at around 89 percent in 2006, is expected to remain the same during 2007, which will maintain

(11)

the similar price range as registered in the preceding year. Domestic prices are expected to follow the international prices trend.

The CRISIL report also predicts buoyancy in the domestic steel demand. With healthy activity in pipes and tubes, automobiles and the construction segment, the demand for steel products is all set to scale. The report predicts a double-digit growth in demand for flat products with 11 percent to 21 Mn Tons during 2007-08, where as demand for long products is expected to grow by 7.6 percent to 19 Mn Tons.

The Eleventh Five Year Plan projects a 9% average annual growth in our GDP. Higher expectations to see a massive increase in investment in infrastructure is probable.

Consequently, massive growth in demand for steel in the next few decades is also credible – perhaps to levels never visualized before.

In view of the above M/s. N.R. Ispat Private Limited has proposed establish a mini Integrated Steel Plant in Raigarh District.

will be continuously fed into the kiln along with coal which has dual role of fuel as well as reductant. Dolomite will be added to scavenge the Sulphur from the coal. A number of air tubes will be provided along the length of the kiln.

The desired temperature profile will be maintained by controlling the volume of the combustion air through these tubes. The Carbon monoxide generated due to the combustion of coal, reduces the iron ore and convert it into sponge iron. The rotary kiln is primarily divided into two zones viz. the pre heating zone and the reduction zone. The preheating zone extends over 30 to 50 % of the length of the kiln and in this the moisture in the charge will be driven off and the volatile matter in the coal will be burnt with the combustion air supplied through the air tubes. Heat from the combustion rises the temperature of the lining and the bed surface. As the kiln rotates, the lining transfers the heat to the charge. Charge material, pre-heated to about 1000oC enters the reduction zone. Temperature of the order of 1050oC will be maintained in the reduction zone, which is the appropriate temperature for solid state reduction of iron oxide to metallic iron. This hot material will be transferred to rotary cooler. In rotary cooler the material will cool from 1000oC to 100oC in cooler by spraying water. The cooler discharge material consists of sponge iron lumps, sponge iron fines and char. Magnetic and non-magnetic material will be separated through magnetic separators and stored in separate bins.

2.6.5.2 STEEL MELTING SHOP 2.6.5.5.1 Induction furnaces

Initially scrap & other metallics such as pig Iron will be charged into the induction furnace.

After scrap & other metallics are fully melted, the temperature of the melt reaches above 1600oC, then DRI will be continuously charged into the furnace. As soon as the charge is melted, bath samples will be taken and temperature will be measured. There will be 2 nos.

of induction furnaces in the SMS plant each of 10T capacity.

(20)

2.6.5.5.2 Concast Machine

Billets will be produced in concast machine

2.6.5.3 ROLLING MILL (Manufacturing of TMT Bars)

The company has proposed to establish a rolling mill with a capacity of 60,000 TPA. Furnace oil will be used as fuel in the reheating furnace.

2.6.5.4 POWER GENERATION

(TOR # 20)

Waste Heat Recovery Boilers will be installed behind the DRI kiln in bypass configuration.

Electricity generation in the proposed power plant is characterized by the main source of heat generation being firing of coal, char and waste heat of DRI kilns. The waste gases from the DRI kilns will pass through WHRB’s to generate Power. Steam is produced in a boiler, and it drives a turbine connected to an alternator. Heat energy is converted to electric energy within the so-called steam cycle. The flue gases after ABC will be taken to unifired furnace chamber and then flow over banks of super heater, convective evaporator and economizer before being discharged to atmosphere through ESP, ID fan and stack. In the Fluidized Bed Combustion boiler envisaged, combustion of fuel particles is achieved in suspension with an inert aggregate i.e. sand. Combustion air will be fed through air nozzles from underneath into the sand fuel bed. Oil burner will be provided for start up and low load flame stabilization. The fuels proposed in FBC Boiler are coal & dolochar. The flue gases will pass over various heat transfer surfaces to ESP and then finally discharged into chimney by ID fan. The condensate after condenser of STG will be pumped to a common deaerator by condensate extraction pumps. Feed water from the deaerator will be pumped to the waste heat recovery boiler as well as FBC boiler by boiler feed pumps.

The steam generated from both the WHRB and FBC boilers will drive the steam turbine through a common steam header.

(21)

2.6.5.5 FLUE GAS UTILIZATION

(TOR # 20)

From DRI Kilns:

The hot gases from DRI kilns will be taken to WHRB and after heat recovery it will be used for Power Generation. A total of 4 MW will be generated through flue gases from DRI.

3.1.4AIR QUALITY

(TOR # 9)

The ambient air quality with respect to the study zone of 10 Km. radius around the plant site forms the baseline information. The study area represents mostly rural environment. The various sources of air pollution in the region are vehicular traffic, dust arising from unpaved village roads. The Prime objective of baseline air quality survey is to assess the existing air quality of the area. This will also be useful is assessing the conformity to standards of the ambient air quality during the plant operation.

3.1.4.1 SELECTION OF SAMPLING STATIONS

The base line status of the ambient air quality can be assessed through scientifically designed Ambient Air Quality Monitoring Network.

The selection of sampling locations in the air quality surveillance programme is based on the following.

(a) Representation of project site.

(b) Representation of down wind direction.

(c) Representation of cross sectional distribution in the down wind direction.

(d) Representation of residential areas.

(e) Representation of regional background levels.

Eight nos. of Ambient Air Quality Monitoring Stations were established with in the study zone of the plant in accordance with CPCB guidelines. One AAQMS was located in Taraimal RF area.

The sampling locations and their distances are shown in Table 3.1.1 and in fig 3.2 The Max., Min., Avg., and 98th percentile values for all the sampling locations for RSPM, SPM, SO2 and NOX are shown in Table 3.1.2 to 3.1.9.

3.2 NOISE ENVIRONMENT

The physical description of sound concerns its loudness as a function of frequency. Noise in general is sound, which is composed of many frequency components of various loudness distributed over the audible frequency range. Various noise scales have been introduced to describe, in a single number, the response of an average human being to a complex sound made up various frequencies at different loudness levels. The most common and heavily favored of those scales is the weighted decibel (dBA). This is more suitable for audible range of 20 to 20,000 Hertz. The scale has been designed to weigh various components of noise according to the response of a human ear.

The impact of noise sources on surrounding community depends on

− Characteristics of noise sources (instantaneous, intermittent or continuous in nature). It is well known that steady noise is not as annoying as one that is continuously varying in loudness.

− The time, at which noise occurs, for example loud noise levels at night in residential areas are not acceptable because of sleep disturbance.

− The location of the noise source, with respect to noise sensitive area, which determines the loudness and period of noise exposure.

The environmental impact of noise can have several effects varying from Noise Induced Hearing Loss (NIHL) to annoyance depending on loudness of Noise levels.

The environmental impact assessment of noise from the plant can be carried out by taking into consideration of various factors: potential damage to hearing, potential physiological responses, annoyance and general community responses.

The main objective of noise level monitoring is to assess the background noise levels in different zones viz., industrial, commercial, residential and silence zones within the study area.

(35)

The basic studies conducted were

a. Assessment of background noise levels.

b. Identification and monitoring the major noise generating sources in the study area.

c. Impact of noise on general population in the study zone of 10 Km. radius.

3. 2. 1 RECONNAISSANCE

Noise levels were measured at different locations within 10 Km. radius of the plant such as villages, bus stands etc.

3.2.1.1 BACKGROUND NOISE

Baseline noise data has been measured at different locations using A-weighted sound pressure level meter. The equivalent day-night noise levels in the study zone are ranging from 44.70 dBA to 48.45 dBA.

3.2.1.2 SOURCES OF NOISE

Typical considerations in environmental noise assessment can be divided into two categories, one is related to noise sources and the other related to potential receiver.

Two quantities are needed to describe completely the strength of the source. They are sound power level and directivity. Sound power levels measures the total sound power radiated by the source in all directions where as directivity is a measure of difference in radiation with direction.

This concept of sound power level and directivity index makes it possible to calculate the sound pressure level created by the source.

3.2.2 COMMUNITY NOISE

The ambient noise level is characterized by significant variations above a base or a residual noise level. The residual noise level is that level below which the ambient noise does not seem to drop during a given time interval and is generally caused by the unidentified distant sources. It differs in rural and urban areas. At night, its level is low due to lesser elements of noise. The

(36)

annoyance that people experience depends upon the number of noise elements that produce noise concurrently at a given time that occur during a time interval.

The noise rating developed by EPA for specification of community noise from all sources is the day night sound level, Ldn. It is similar to a 24 hour equivalent sound level except that during the night period, which extends from 10.00 p.m. to 7.00 a.m. A 10 dBA weighing penalty is added to the account for the fact that noise at night when people are trying to sleep is judged more annoying than the same noise during the day time.

The Ldn for a given location in a community is calculated from an hourly equivalent sound level given be the following equation.

Ldn =10 log (1/24 [15 (10(Ld/10) + 9 (10(Ln+10)/10 )] )

Where Ld is the equivalent noise level during day time (7A .M. to 10 P.M.) Ln is the equivalent noise level during night time (10 P.M. to 7 A.M.) 3.2.2.1 OCCUPATIONAL EXPOSURE

To assess the magnitude of impact due to noise sources, it is essential to know the following.

a. The duration of sound.

b. Distribution through the working day.

c. Overall noise levels.

d. It’s composition including frequency and intensity at various intervals of time.

Other factors regarding receiver include a. The age of the individual.

b. The sensitivity of the individual.

c. The efficiency of the protective devices used.

After characterizing the noise sources noise at receiver’s location, the impact must be assessed.

The environmental impact of noise can lead to the following effects.

(37)

a. Damages the hearing capacity.

b. Interference in communication.

c. Interference with work.

d. Interference with sleep.

e. Causes annoyance

3. 2. 3. NOISE LEVEL OBSERVATIONS IN THE STUDY AREA

Baseline noise levels have been monitored at different locations within the study zone of the plant. Eight nos. of stations have been selected for measurement of noise levels and their distances with respect to site are shown in table 3. 2.1.
