1.3.4 IMPORTANCE OF PROJECT<br />
Steel Production in <strong>India</strong><br />
<strong>India</strong> is one of the few countries where the steel industry is poised for rapid growth.<br />
<strong>India</strong>'s share in world production of crude steel increased from 1.5% in 1981 to around<br />
3.5 % in 2004. While plant closures and privatization are rare in <strong>India</strong>, the <strong>private</strong> sector<br />
is considered to be the engine of growth in the steel industry and technological changes<br />
and modernization are taking place in both the public and the <strong>private</strong> sector integrated<br />
steel plants in <strong>India</strong>. Steel production of <strong>India</strong> accounted for 14.33 million tons in 1990-<br />
91, which gradually increased to 36.12 million tones in 2003-04, as shown in Table<br />
below. The <strong>India</strong>n steel industry got a giant importance in the recent past when the Tata<br />
Steel purchased the Corus steel. Today <strong>India</strong> plays a significant role in the production of<br />
steel in the world. The <strong>India</strong>n steel industry is growing at 8.74 % of CAGR.<br />

PROJECT DESCRIPTION<br />
2.1 TYPE OF PROJECT<br />
Steel consists mostly iron, with a carbon content between 0.02% and 1.7 or 2.04% by<br />
weight (C: 1000–10, 8.67 Fe), depending on grade. Carbon is the most cost-effective<br />
alloying material for iron, but various other alloying elements are used such as<br />
manganese and tungsten. Carbon and other elements act as a hardening agent, preventing<br />
dislocations in the iron atom crystal lattice from sliding past one another. Varying the<br />
amount of alloying elements and form of their presence in the steel (solute elements,<br />
precipitated phase) controls qualities such as the hardness, ductility, and tensile strength<br />
of the resulting steel. Steel with increased carbon content can be made harder and<br />
stronger than iron, but is also more brittle. The maximum solubility of carbon in iron (in<br />
austenite region) is 2.14% by weight, occurring at 1149 °C; higher concentrations of<br />
carbon or lower temperatures will produce cementite. Alloys with higher carbon content<br />
than this are known as cast iron because of their lower melting point. Steel is also to be<br />
distinguished from wrought iron containing only a very small amount of other elements,<br />
but containing 1-3% by weight of slag in the form of particles elongated in one direction,<br />
giving the iron a characteristic grain.<br />

2.2 NEED FOR THE PROJECT<br />
Driven by buoyant steel-intensive economic activity including construction and<br />
infrastructure building in many developing economies, global apparent<br />
consumption of steel has increased at an average pace of more than 7 percent per<br />
annum since 2002 to reach a record level of 1.113 billion tonnes last year. To<br />
meet this rise in demand, steel production growth has accelerated sharply,<br />
reaching 1.24 billion tonnes in 2006, up by as much as 393 million tonnes (or<br />
46%) compared to its level of 850 million tonnes in 2001. This growth in demand<br />
for steel is creating a favourable situation for many steelmakers.<br />
<strong>India</strong>'s rapid economic growth is being built on a frame of steel. Soaring demand<br />
by sectors like infrastructure, real estate and automobiles, at home and abroad,<br />
has put <strong>India</strong>'s steel industry on the world map.<br />
Growth potential: The per capita steel consumption in <strong>India</strong> is abysmally low at<br />
around 30 kgs as compared to 210 kgs of China and over 400 kgs in the<br />
developed countries. This wide gap in relative steel consumption indicates that<br />
the potential ahead for <strong>India</strong> to raise its steel consumption is high.<br />
Continued demand: Meteoric rise in steel prices since 2003 until early 2005<br />
helped the domestic steel companies immensely as many of them managed to<br />
reduce their debt burden considerably, helping them either turn into profits or<br />
increase the same significantly. Going forward, the demand for the metal is likely<br />
to sustain on the back of continuing demand from the US and other South East<br />
Asian nations.<br />

Domestic help: A robust housing and infrastructure sector, with growth potential<br />
in the auto and the consumer durables sectors is likely to be a big positive for the<br />
domestic steel sector.<br />

The other consumables of the process include oxygen lancing pipes and oxygen used for<br />
opening the furnace tap-holes, and the refractory for the lining of pans / runners used for<br />
alloy collection.<br />
PROCESS DESCRIPTION: -<br />
Standard Silico Manganese is smelted at about 1700 – 1800 ºC. This is achieved by a<br />
conventional Submerged Arc Electric Furnace. The three carbon electrodes, partially<br />
submerged in the charge, are supported on hydraulic cylinders for upward and downward<br />
movements to maintain the desired electrical conditions in the furnace.<br />
The body of the furnace is cylindrical in shape, and is lined with firebricks, silicon<br />
carbide bricks and carbon tamping paste. Two tap-holes are provided at 120º. Apart form<br />
draining out both the molten alloy and the slag. During the repair works of one of the tap<br />
holes the other will function as standby. The raw materials are thoroughly mixed in the<br />
proper proportion before being charged into the furnace. Manual poking rods or stoker<br />
car are used for stoking the charge on the furnace top. As the charge enters the smelting<br />
zone, the alloy formed by chemical reactions of the oxides and the reductant, being heavy<br />
gradually settles at the bottom. The slag produced by the unreduced metal oxides and the<br />
flux, being relatively lighter, floats on the alloys surface. At regular intervals the furnace<br />
is tapped.<br />
The tap hole is opened by Oxygen lancing pipe and after tapping is completed, it is<br />
closed by clay plug. The liquid Silico manganese and the slag flow into the C.I. Pan. The<br />
slag being lighter overflow from the C.I. Pan and is taken into the sand mould.<br />

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

The impact of noise sources on surrounding community depends on:<br />
‣ Characteristics of noise sources (instantaneous, intermittent or continuous in nature).<br />
It is well known that steady noise not as annoying as one that is continuously varying<br />
in loudness.<br />
‣ The time at which noise occurs, for example loud noise levels at night in residential<br />
areas are not acceptable because of sleep disturbance.<br />
‣ The location of the noise source, with respect to noise sensitive area, which<br />
determines the loudness and period of noise exposure.<br />
The environmental impact of noise can have several effects varying from Noise Induced<br />
Hearing Loss (NIHL) to annoyance depending on loudness of Noise levels.<br />
The environmental impact assessment of noise from the plant can be carried out by<br />
taking into consideration of various factors: potential damage to hearing, potential<br />
physiological responses, annoyance and general community responses.<br />
The main objective of noise level monitoring is to assess the background noise levels in<br />
different zones viz., industrial, commercial, residential and silence zones within the study<br />
area. The basic studies conducted were<br />
a. Assessment of background noise levels.<br />
b. Identification and monitoring the major noise generating sources in the study area.<br />
c. Impact of noise on general population in the study zone of 10 kms. radius.<br />
3. 2. 1 Reconnaissance<br />
Noise levels were measured at different locations within 10 Km. radius of the proposed<br />
Project such as villages, bus stands etc.<br />

3.2.1.1 Background noise<br />
Baseline noise data has been measured at different locations using A-weighted sound<br />
pressure level meter. The equivalent day-night noise levels in the study zone are ranging<br />
from 44.10 dBA to 51.65 dBA.<br />
3.2.1.2 Sources of noise<br />
Typical considerations in environmental noise assessment can be divided into two<br />
categories, one is related to noise sources and the other related to potential receiver.<br />
Two quantities are needed to describe completely the strength of the source. They are<br />
sound Power level and directivity. Sound Power levels measures the total sound Power<br />
radiated by the source in all directions where as directivity is a measure of difference in<br />
radiation with direction. This concept of sound Power level and directivity index makes it<br />
possible to calculate the sound pressure level created by the source.<br />
3.2.2 Community noise<br />
The ambient noise level is characterized by significant variations above a base or a<br />
residual noise level. The residual noise level is that level below which the ambient noise<br />
does not seem to drop during a given time interval and is generally caused by the<br />
unidentified distant sources. It differs in rural and urban areas. At night, its level is low<br />
due to lesser elements of noise. The annoyance that people experience depends upon the<br />
number of noise elements that produce noise concurrently at a given time that occur<br />
during a time interval.<br />
The noise rating developed by EPA for specification of community noise from all<br />
sources is the day night sound level, Ldn. It is similar to a 24 hour equivalent sound level<br />
except that during the night period, which extends from 09.00 p.m. to 6.00 a.m. A 10<br />

Chapter – 3<br />
dBA weighing penalty is added to the account for the fact that noise at night when people<br />
are trying to sleep is judged more annoying than the same noise during the day time.<br />
The Ldn for a given location in a community is calculated from an hourly equivalent<br />
sound level given by the following equation.<br />
Ldn =10 log (1/24 [15 (10 (Ld/10) + 9 (10 (Ln+10)/10 )] )<br />
Where Ld is the equivalent noise level during day time (6A .M. to 9 P.M.)<br />
Ln is the equivalent noise level during night time (9 P.M. to 6 A.M.)<br />
3.2.2.1 Occupational exposure<br />
To assess the magnitude of impact due to noise sources, it is essential to know the<br />
following.<br />
a. The duration of sound.<br />
b. Distribution through the working day.<br />
c. Overall noise levels.<br />
d. It's composition including frequency and intensity at various intervals of time.<br />
Other factors regarding receiver include:<br />
a. The age of the individual.<br />
b. The sensitivity of the individual.<br />
c. The efficiency of the protective devices used.<br />
After characterizing the noise sources noise at receiver's location, the impact must be<br />
assessed. The environmental impact of noise can lead to the following effects.<br />
a. Damages the hearing capacity.<br />
b. Interference in communication.<br />
c. Interference with work.<br />
d. Interference with sleep.<br />
e. Causes annoyance.<br />

Ground Water Quality (TOR # 19)<br />
Ground water samples have been collected and analyzed for various parameters like pH,<br />
Suspended Solids, Total Dissolved Solids, Temperature, Total Hardness, Calcium<br />
Hardness, Magnesium hardness, Alkalinity, Fluoride, Chloride, Sulphates, Nitrates,<br />
Phenolic compounds, Heavy metals etc. and is compared with the standards to know the<br />
water quality. Selection of sampling locations will be generally done based on the<br />
following factors:<br />
i) Proximity of the industries to the site.<br />
ii) Residential areas.<br />
iii) Representation of Project site.<br />
Eight numbers of ground water samples from bore wells were collected from the near by<br />
villages to assess ground water quality impacts. The ground water sampling locations and<br />
their distances from the proposed Project site are shown in Table 3.3.3. These water<br />
samples are analysed for various parameters as per IS: 10500. The ground water<br />
characteristics were shown in table Nos. 3.3.4. to 3.3.11. The ground water monitoring<br />
stations are shown in Fig. 3.4. There is no organic contamination of the ground water.<br />
No heavy metals are present in ground water. The hardness in the water is slightly higher<br />
which is due to the geological formation beneath the ground surface but this is less than<br />
the maximum acceptable levels.<br />

ENVIRONMENT MONITORING PROGRAMME<br />
4.0 INTRODUCTION<br />
Impact prediction is a very important phenomenon in evaluating the environmentally<br />
potential adverse impacts for any proposed industrial project. The impact prediction is<br />
always carried out under worst possible conditions so as to mitigate or to eliminate the<br />
environmental hazards. These predictions thus calculated are superimposed over the<br />
baseline data to calculate the net impact on the environment after the expansion project<br />
comes into production.<br />
4.1 AIR ENVIRONMENT<br />
It is possible that increase in the background concentration of even a minor constituent of<br />
the atmosphere may lead to significant changes in the atmospheric properties. So these<br />
changes are essential in understanding potential climatic changes due to air pollutants. For<br />
example under strongly stable condition, disturbances are highly damped and mixing of<br />
pollutants is strongly suppressed. It is under such conditions that the worst air pollution<br />
episodes have occurred.<br />
Prediction of impacts is the most important component in the environmental impact<br />
assessment studies. Several scientific techniques and methodologies are available to<br />
predict impacts of developmental activities on physico, ecological and socioeconomic<br />
environments. Such predictions are superimposed over the baseline (pre project) status of<br />

The mathematical model used for predictions in the present study include, steady state<br />
Gaussian Plume dispersion model designed for multiple point sources for air quality,<br />

4.1.1 IMPACT ON TOPOGRAPHY AND CLIMATE<br />
4.1.1.1 IMPACT ON TOPOGRAPHY<br />
The major envisaged topographical changes would be <strong>limited</strong> to the immediate vicinity of<br />
the plant. The change in topography will be only due to man made structures like<br />
Industrial complex and Administrative building. Similarly, it will invite positive benefits<br />
in the form of land leveling and green belt development in the plant vicinity.<br />
4.1.1.2 IMPACTS ON CLIMATE<br />
As the temperature of the effluent gases will not be high, generally this will not cause any<br />
thermal imbalance as extensive greenbelt will be developed within the plant premises.<br />
However, there will be natural dispersion of heat due to unstable conditions during day<br />
and as such there would be no significant micro / macro climatological changes of any<br />
consequence.<br />
4.1.2 PREDICTION OF IMPACTS ON AIR ENVIRONMENT (TOR # 11)<br />
It is a<strong>bs</strong>olutely essential to study the impacts of air pollution on its environs due to the<br />
proposed Plant. These impacts are predicted with the help of Gaussian Mathematical<br />
model. These models stimulate the relationship between air pollutant emissions from the<br />
stack and the resultant impact on the air quality within the study zone. The pollutants<br />
emitted into the atmosphere get diluted immediately and is transported and mixed with the<br />
surrounding air. The basic purpose of these mathematical models are to represent these<br />
processes mathematically. Computer models are used for predicting the Ground Level<br />
Concentrations (GLC) for spatial variations.<br />

In the present case, computation of 24 hour average Ground Level Concentrations are<br />
carried out using ATDM (All Terrain Dispersion Model). This model is based on the<br />
algorithms of two USEPA dispersion models, ISCST2 and COMPLEX 1 and also<br />
incorporates the procedure used in POSTIT post processor to calculate the concentrations<br />
in intermediate terrain.<br />
ATDM is based on Guassian dispersion, which incorporates the Pasquill Gifford<br />
dispersion parameters for estimating the horizontal cross wind and vertical dispersion.<br />
ALL TERRAIN DISPERSION MODEL<br />
The All Terrain Dispersion Model (ATDM) is a Gaussian Dispersion model that calculates<br />
the concentration from point, area and volume source emissions in simple, intermediate<br />
and complex terrain.<br />
v For receptors located in simple terrain (terrain below stack top) ATDM uses the<br />
dispersion algorithms from ISCST2 model.<br />
v For receptors located in complex terrain (terrain above plume centre line). ATDM<br />
uses the dispersion algorithm from the COMPLEX 1 model.<br />
v For receptors located in intermediate terrain, ATDM uses both ISCST2 and<br />
COMPLEX1 algorithms to estimate the 24 hourly average concentration at each<br />
receptor location and reports the larger of the two values as the calculated<br />
concentration.<br />
ATDM calculates the plume rise and plume and plume centre line elevation for a given<br />
source to determine whether a receptor is located in a simple terrain, complex terrain or in<br />
intermediate terrain w.r.t. source. Depending upon the terrain regime of the receptor, the<br />
model then uses on of the three approaches described below to calculate the one-hour<br />
average concentration at that receptor resulting from the emissions from the sources.<br />
Simple Terrain<br />
For receptors located in simple terrain (terrain below stack top), ATDM uses the<br />
dispersion algorithms form the ISCST2 model. The ISCST2 model is a Gaussian<br />
dispersion model that calculates concentrations using the pasquill – Gifford dispersion<br />
coefficients (Rural mode) and the Briggs urban dispersion coefficients (Urban mode). As<br />
in ISCST2, ATDM accounts for the effects of building down wash.<br />

Chapter – 4<br />
User specified terrain stack base elevations are used in the ISCST2 dispersion calculations<br />
according to EPA recommended approach for simple terrain. In this approach, the final<br />
plume rise is calculated to determine the plume centerline elevation above the sea level<br />
and this elevation is used for all downwind distances from the stack. Therefore, the plume<br />
centerline remains parallel to sea level without regard to changes in the underlying terrain.<br />
Complex terrain<br />
For receptors located in complex terran (above plume centreline), ATDM uses the<br />
dispersion algorithm from the COMPLEX1model. This algorithm is similar to that of the<br />
ISCST2 model in that it uses the same Gaussian dispersion equation and plume rise<br />
equations.<br />
Intermediate Terrain<br />
A receptor is said to be located in intermediate terrain if its elevation is greater that the<br />
stack top elevation but less than that plume centreline elevation. For such receptors, EPA<br />
recommends that both the ISCST 2 and COMPLEX dispersion algorithms be used to<br />
estimate the 24 hourly average concentration at the receptor location and the larger of the<br />
two values be used as the calculated concentration.<br />
Multiple sources<br />
When modeling multiple sources, ATDM sums the calculated one hour average<br />
concentrations from each source to estimate the total concentration at a given receptor<br />
location.<br />

Theta method (Ref: On site meteorological program guidance for regulatory modeling<br />
applications, US-EPA).<br />

The hourly σA values calculated by the data logger are used for arriving at the hourly<br />
stability's by the following procedure:<br />
The following section describes the method of estimating stability categories in terms of<br />
standard deviation of the lateral wind direction fluctuations (σA) and the scalar mean wind<br />
speed (us). The lateral wind direction turbulence criteria for initial estimate of PG stability<br />
category are given in Table - 4.1.1. The wind speed adjustments for determining final<br />
estimate of PG stability category from σA is given in Table - 4.1.2. The criteria laid down<br />
in the tables below are for the data collected at 10m and roughness length of 15 cm. Night<br />
time is defined as the period from one hour before sunset to one hour after sunrise. The<br />
method specifies that the data need to be collected at 10 m height. The relationship<br />
employed in the estimation methods assumes conditions are of steady state.<br />

STACK HEIGHT BASED ON SO 2 EMISSION<br />
Total coal consumption for 2 x 100 TPD kilns : 200 TPD<br />
Max. Sulphur content in coal : 0. 45% (By mass)<br />
SO 2 emission (Q) : 200 x 1000 x (0.45/100) x 2/24<br />
: 75 kg/hr<br />

: 14 (75) 0.3<br />
: 5.12 m or say 52 m<br />
As 4 x 100 TPD kilns are proposed in the expansion, there will be two nos. of<br />
combined Stacks (each with twin flues) of 60 m height will be provided for effective<br />
dispersion of sulphur dioxide emissions into the atmosphere.<br />

Hence a stack of 72 m height will be provided to the AFBC boiler stack for effective<br />
dispersion of emissions into the atmosphere.<br />
4.1.3.3 STACK HEIGHT CALCULATION (ROLLING MILL)<br />
FO Consumption per Rolling mill : 11.9 TPD<br />
Sulphur content in FO : 4.5 % (by mass, Max.)<br />
SO2 emission : 11.9 X 1000 X 4.5 X 2/24x100<br />

Stack Height H, : 14 (Q) 0.3<br />
: 14 (44.625) 0.3 = 43.75 m or say 45 m<br />
Hence stack of 45 m height will be provided for effective dispersion of emissions into<br />
the atmosphere.<br />
Sources of Air Emissions :<br />
The main sources of fugitive emissions are raw material unloading, raw material handling,<br />
crushers of coal, material transfer points, storage bins, etc. Dust generated from raw<br />
material unloading areas is controlled by providing dust suppression system. In other<br />
areas specified above dust extraction system with bag filters will be provided to control<br />
the particulate emission.<br />
The waste flue gases from kilns will be allowed to pass through a Waste Heat Recovery<br />
Boiler (WHRB) and then after heat recovery the gases will pass through an Electrostatic<br />
Precipitator (ESP) to bring down the particulate matter to less than 50 mg/Nm 3 and will be<br />
let out into the atmosphere through two nos. of combined stacks (each with twin flues)<br />
each of 60 m height for effective dispersion of emissions into the atmosphere.<br />
Fumes will be evacuated directly from both the Induction Furnaces through a swiveling<br />
type of hoods with an air-cooled ducting. The duct carrying fumes from the Induction<br />
furnace and CCM will join a mixing chamber from where the gases will be led to the Bag<br />
House by means of an ID fan. Clean gases having less than 50 mg/Nm 3 of particulates will<br />
be let out through two common stacks (with two flues) each of 30 m height.<br />
In Reheating Furnace the fuel proposed to be used is FO. Stack of 45 m height will be<br />
provided for effective dispersion of SO2 emissions into the atmosphere.<br />
The primary & secondary fugitive emissions from submerged Electric arc furnaces from<br />
Ferro alloys unit will be treated in Fume extraction & cleaning system comprising of<br />

suction hoods, bag filters etc . The outlet dust emissions in the exhaust gases will be less<br />
than 50 mg/Nm 3 . The treated gases will be discharged into the atmosphere through stacks<br />

The waste flue gases from AFBC boiler will pass through an Electrostatic Precipitator<br />
(ESP) to bring down the particulate matter to less than 50 mg/Nm 3 and will be let out into<br />
the atmosphere through a stack of 72 m height for effective dispersion of emissions into<br />
the atmosphere.<br />
The predicted max. incremental rise in SPM concentrations (24 hourly) will be 0. 6µg/m 3 at<br />
a distance of 1100 m from the origin stack in the down wind direction over the baseline<br />
concentrations.<br />
The predicted max. incremental rise in SO 2 concentrations (24 hourly) will be 8.9 µg/m 3 at<br />
a distance of 1100 m from the origin stack in the down wind direction over the baseline<br />
concentrations.<br />
The predicted max. incremental rise in NOx concentrations (24 hourly) will be 4.7 µg/m 3<br />
at a distance of 1100 m from the origin stack in the down wind direction over the baseline<br />
concentrations.<br />
The net resultant concentrations (Maximum baseline conc. + predicted incremental rise in<br />
conc.) of SPM, SO 2 and NO X are shown in Table No. 4.1.4. The net resultant<br />
concentrations of SPM, SO 2 and NO X are well within the National Ambient Air Quality<br />
Standards (NAAQS) when the plant commences the operation. Hence there will not be<br />
any adverse impact on air environment due to the proposed expansion project.<br />

from the source due to wave divergence.<br />
An additional decrease in sound pressure level with distance from the source is expected,<br />
due to atmospheric effect or its interaction with objects in the path of transmission. For<br />

hemispherical sound wave propagation through homogeneous loss free medium, one can<br />
estimate noise levels at various locations, due to different sources using model based on<br />
first principle, as per the following equation:<br />
Lp2 = Lp1 – 20 Log (r2/r1) - Ael.2<br />
Where Lp1 and Lp2 are sound pressure levels at points located at distance r1 and r2 from<br />
the source and Ae1.2 is the excess attenuation due to environmental conditions. Combined<br />
affect of all the sources then can be determined at various locations by logarithmic<br />
addition.<br />
It is first approximation one can assume that for all general population in the villages, every<br />
noise source in the plane is a point source. The average equivalent sound power level of<br />
such a point source can be estimated for different distances and directions from<br />
hypothetical source by applying following equation:<br />
Lp = Lw - 20 Log r – Ae – 8<br />
Where Lw is the sound power level of the source, Lp is sound pressure level at a distance r<br />
and Ae is environmental attenuation factor. A combined noise level Lp (total) of all the<br />
sources at a particular place is given by:<br />
Lp(total) = 10 Log (10 Lp1/10) + 10 (Lp2/10) + ---------)<br />
Major noise generating sources were identified from the proposed activity for prediction<br />
purposes. The major noise generating sources are STG, DG set & compressors. The<br />
predictions have been made to represent the worst case. The noise levels at various<br />
distances were calculated using wave divergence model.<br />
The model was run for ascertaining the areas where we could get the noise levels of 35,<br />
45, 50,55,60,65, and considering the other noise generating sources from the plant.<br />
Silencers will be provided to the DG Sets. All machinery will be manufactured keeping in<br />
view of the MOEF/OSHA standards on Noise levels. The Ambient Noise levels will be<br />
within the standards prescribed by MOE&F, GOI vide Notification dated 14-02-2000 under<br />
the Noise pollution (regulation & control) Rules, 2000.<br />
4.3.2. PREDICTION OF IMPACTS ON COMMUNITY<br />
Day and Night sound pressure levels, Ldn is often used to describe the community noise<br />
exposure which include 10 dBA night time penalty. As the nearest human settlement is<br />
about 2.5 Km. from the plant, the impact of noise on general population would be<br />
insignificant.<br />

Chapter – 4<br />
As per the WHO recommendation, there is no identified risk and damage of hearing due to<br />
the noise levels (Leq = 8 hours) less than 75 dBA. Most of the international damage risk<br />
criteria for hearing loss permit (Leq = 12 hours) upto 87 dBA. Further, WHO<br />
recommendation on community noise annoyance, permits day time out door noise levels<br />
of 55 dBA. Leq and night time outdoor noise level of 45 dBA leq to meet sleep criteria<br />
i.e. Leq (24 hours) = 52.2. dBA and Ldn = 5.5 dBA.<br />
4.3.3. PREDICTION OF IMPACT ON OCCUPATIONAL HEALTH<br />
The damage risk criteria as enforced by OSHA (Occupation Safety and Health<br />
Administration) to reduce hearing loss, stipulates that noise level upto 85 dBA are<br />
acceptable for 8 hour working shift per day. Plant authorities will provide ear plugs to the<br />
employees and will be enforced to be used by the employees.<br />
4.4 PREDICTION OF IMPACTS ON LAND ENVIRONMENT<br />
90 acres of land is in the possession of the management. As there are no endangered<br />
species in the vicinity of the proposed activity, there should not be any concern for the loss<br />
of important germoplasm that needs conservation.<br />
The flue gases from the kilns will pass through Waste Heat Recovery Boiler & then<br />
through ESP to bring down the particulate emission to less than 50 mg/NM 3 and will be<br />
discharged through two nos. of combined stacks (each stack with twin flues) each of 60m<br />
height for effective dispersion of emissions into the atmosphere.<br />
To control the fugitive emissions dust extraction system and dust suppression syste m will<br />
be installed at all the possible dust emanating areas. All required pollution control systems<br />
will be installed in the proposed expansion project. Hence it will not have any impact on<br />
nearby top soil.<br />
There will not be any process waste water & cooling water blowdown from the steel plant<br />
as closed circuit cooling system is proposed in the expansion. The boiler blowdown, DM<br />
plant regeneration water from the power plant will be treated in a neutralization tank and<br />
utilized for onland for irrigation within the premises. Zero effluent discharge will be<br />
maintained after expansion also. Hence there will not be any adverse impact on land<br />
environment due to the proposed expansion project. Solid waste generated from the plant<br />
will be disposed / utilized as per the norms. Hence there will not be any adverse impact on<br />
land environment due to the proposed expansion project.<br />

Chapter – 4<br />
The land use pattern of the study area will certainly improve due to the proposed activity.<br />
Land price in the area will increase and will benefit the local people. This industry may<br />
attract some ancillary works also which will also help in improving the land use pattern of<br />
the area. Greenbelt is considered essential for maintaining the stability of the environment<br />
of the area. 30 Acres of extensive greenbelt will be developed in the plant including<br />
existing Greenbelt.<br />
4.5 PREDICTION OF IMPACTS DUE TO VEHICULAR MOVEMENT (TOR # 10)<br />
All the trucks used for transportation of raw materials will be covered. Hence there will<br />
not be any fugitive dust generation during transportation of raw materials. Pucca road exist<br />
upto the site. The existing road is capable of a<strong>bs</strong>orbing this additional truck movement.<br />
Hence there will not be any adverse impact on vehicular traffic due to the proposed<br />
expansion project.<br />
4.6 PREDICTION OF IMPACTS ON SOCIO ECONOMIC ENVIRONMENT<br />
The local areas will be benefited by way of generation of employment opportunities,<br />
increased demand for local products and services. There will be an overall improvement<br />
in the income level of the local people.<br />
The project creates employment to about 250 persons once the plant is commissioned and<br />
for 500 persons during construction stage. Priority will be given to locals for Semi-Skilled<br />
and Unskilled jo<strong>bs</strong>. With the implementation of the proposed expansion project, there will<br />
be lot of scope for more industrial investments which in turn will benefit the nation.<br />
The project authorities intend to provide welfare activities recreational facilities in the<br />
surrounding villages once the expansion plant commences production. The project<br />
authorities intend to conduct regular health checkups in the surrounding villages.<br />
Therefore there will be a certain enhancement of educational and medical standards of<br />
people in the study area. There will be generally positive and beneficial impacts by way of<br />
economic improvements, transportation, aesthetic environment and business generation.<br />
There will be an overall upliftment of socio-economic status of people in the area.<br />

To know the effectiveness of environmental mitigation measures post project<br />
environmental monitoring program will be strictly followed as per statutory requirement.<br />
• Online monitors will be installed to rotary kilns to monitor particulate matter from<br />
the exhaust gases after treatment in Electro Static Precipitator (ESP).<br />
• Always particulate matter in the exhaust gas will be maintained below 50<br />
mg/Nm 3 .<br />
• In case if the stack emission is more than the stipulated standard, the interlocking<br />
system proposed will stop the feed to the kiln and eventually there will not be any<br />
production in the unit. Production in the unit will be restarted only when the Air<br />
pollution control systems are able to achieve the norms.<br />
• Energy meters will be provided to all air pollution control systems to ensure<br />
effective operation of the control systems.<br />
• The Fugitive emissions from the Induction furnaces will be sucked through hoods<br />
and will pass through a fume extraction system & cleaning system with bag filters<br />
and discharged into the atmosphere through a stack of 30m height. The outlet dust<br />
emission will be less than 50 mg/NM 3 .<br />
• The emissions from each of the Submerged Electric Arc Furnaces will be<br />
controlled by providing a fume extraction system with bag filters and discharged<br />
into the atmosphere through a stack of 30 m height. The outlet dust emission will<br />
be less than 50 mg/Nm 3 .<br />

ADDITIONAL STUDIES<br />
7.1 RISK ASSESSMENT (TOR # 22)<br />
7.1.1 INTRODUCTION<br />
Risk analysis deals with the identification and quantification of risks, the plant equivalent and<br />
personnel are exposed to, due to accidents resulting from the hazards present in the factory.<br />
Hazard analysis involves the identification and quantification of the various hazards that likely<br />
to occur in the factory.<br />
Both hazard and risk analysis very extensive studies, and require a very detailed design and<br />
engineering information.<br />
The various hazard analysis techniques that may be applied are Hazard and Operability<br />
(HAZOP) studies, Fault - Tree Analysis (FTA), event tree analysis, failure and effects mode<br />
analysis. Risk analysis follows an extensive hazard analysis. It involves the identification and<br />
assessment of risks the neighboring populations are exposed to as result of hazard present. This<br />
requires a through knowledge of failure probability, credible accident scenario, vulnerability of<br />
populations etc. Much of this information is difficult to get or generate. Consequently, the risk<br />
analysis is often confined to maximum creditable accident studies.<br />
7.1.2 SCOPE OF THE STUDY<br />
The scope of study includes the study of proposed operations, storage and handling of raw<br />
materials with respect to Hazard Identification. Risk Assessment and preparation of Disaster<br />
Management plan. Based on the Hazard Identification and analysis, the major disaster scenarios<br />
would be worked out to estimate the consequence of failure. A Disaster Management Plan<br />
(DMP) would also be evolved to meet the emergency situation including the occupational<br />
health and safety.<br />

7.1.5 METHODOLOGY OF MCA ANALYSIS<br />
The MCA Analysis involved ordering and ranking of various sections in terms of potential<br />
vulnerability. The following steps were involved in MCA Analysis.<br />
• Preparation of an inventory of major storages and rank them on the basis of their hazard<br />
properties.<br />
• Identification of potentially hazardous storage sections and representative failure cases from<br />
the vessels and the pipelines.<br />
• Visualization of chemical release scenarios.<br />
• Effect and damage calculation from the release cases through mathematical modeling.<br />
• Inventory Analysis and Fire & Explosion and Toxicity Index (FETI) are the two techniques<br />
employed for hazard identification process.<br />
7.1.6 FIRE & EXPLOSION AND TOXICITY INDEX<br />
The role of Fire & Explosion Index (FEI) aids quantitative hazard identification. The FEI is<br />
calculated by evaluating the loss potential of all the units in the storage area and the hazardous<br />
areas were classified accordingly. The role of FEI is<br />
• Identification of the equipment/areas that could likely contribute to the creation or escalation<br />
of incident and relatively rank the incidents.<br />
• Quantification of the expected damage of potential fire and explosion incidents.<br />
• Preparation of guidelines for mitigating fire hazards.<br />
The loss potential which could actually be experienced under the most adverse operating<br />
conditions is quantitatively evaluated. The FEI is used for any operation in which a flammable,<br />
combustible or reactive material is stored, handled or processed.<br />
FEI = MF * GPH * SPH<br />
Where MF : Material factor<br />
GPH : General Process Hazard<br />
SPH : Special Process Hazard<br />

7.1.7 ASSESSMENT OF RISK AT M/s. BSPL<br />
Based on the storage inventory the following areas are identified as potential safety risk areas<br />
are shown in table 7.1<br />
TABLE 7.1<br />
POSSIBLE RISKS FROM THE PROPOSED STEEL PLANT<br />
S. No. Area Capacity / quantity Hazards identified<br />
1. Coal handling plant - Fire and or dust explosion<br />
2. Coal storage 20,000 tones Fire, spontaneous combustion<br />
3. FO storage 2 x 35 KL Fire<br />
7.1.7.1 COAL HANDLING PLANT - DUST EXPLOSION<br />
Coal dust when dispersed in air and ignited will explode. Crusher houses and conveyor systems<br />
are most susceptible to this hazard. The minimum of explosive concentration of coal dust (33%<br />
volatiles) is 50 grams/m 3 . Failure of dust extraction & suppression systems may lead to<br />
abnormal conditions and increasing the concentration of coal dust to the explosive limits. The<br />
sources of ignition are incandescent bul<strong>bs</strong>, electric equipment & cables, friction & spontaneous<br />
combustion in accumulated dust. Dust explosion may occur without any warning with<br />
maximum explosion pressure upto 6.4 bars. Another dangerous characteristic of dust explosions<br />
is that it sets off secondary explosions after the occurrence of initial dust explosion.<br />
Stock pile area shall be provided with automatic garden type sprinklers for dust suppression as<br />
well as to reduce spontaneous ignition of coal stock piles, necessary water distribution net work<br />
will be provided for distributing water at all transfer points, crusher house, control room, etc.<br />
A centralized control room with microprocessor based control system has been envisaged for<br />
operation of the coal handling plant. Except locally controlled equipment like travelling tripper,<br />
dust extraction / dust suppression / ventilation equipment, sump pumps, water distribution<br />

system all other in line equipment will have provision for local control as well. All necessary<br />
inter local control panels will be provided for safe and reliable operation of the coal handling<br />
plant.<br />
Control measures for coal yard<br />
The entire quantity of coal will be stored in separate stack piles, with proper drains around to<br />
collect washouts during the monsoon. Water sprinkling system will be installed on stocks of<br />
pile to prevent spontaneous combustion and consequent fire hazards. The stack geometry will<br />
be adopted to maintain minimum exposure of stock pile areas towards predominant wind<br />
direction temperature will be monitored in the stock piles regularly to detect any at normal rise<br />
in temperature inside the stock pile to be enable to control the same.<br />
7.1.8 RISK & CONSEQUENCE ANALYSIS OF FIRE<br />
The principle objective of this study is to identify the potential hazards estimate the effects of<br />
hazards to people both with in and outside the plant premises.<br />
− Identification of possible failure cases of the facilities which might affect the population and<br />
property within the plant boundary.<br />
− Assessment of consequential effect on surrounding population, property etc., due to onset of<br />
such failures.<br />
− Suggest recommendations based on consequence analysis relevant to the situations.<br />
7.1.8.1 METHODOLOGY<br />
The hazards expected from this plant include the pool fire situation due to the leakage of FO<br />
from the storage tank. There will be two nos. of FO storage tanks each of 35 KL capacity. The<br />
tank will be made of Mild steel and will be provided with dyke around the tanks. The most<br />
credible failure is due to the rupture of the pipe connecting the storage tank. The worst case can<br />
be assumed as when the entire contents leak out into the dyke forming a pool, which may catch<br />
fire on finding source of ignition.<br />

Chapter – 7<br />
FO STORAGE TANK - POOL FIRE SCENARIO<br />
The maximum quantity of FO stored at site will be 2 x 35 m 3 capacity. In the event of tank<br />
spilling its contents through a small leakage or due to rupture of pipeline connecting the tank<br />
and on ignition fire will ensue. As the tanks are provided with dyke, the fire will be confined<br />
within the dyke. Threshold limit for first degree burns is 4.5 kw/m 2 . Based on these results it<br />
may be concluded that the vulnerable zone in which the thermal fluxes above the threshold limit<br />
for first degree burns (4.5 kw/m 2 ) is restricted to 17 m.<br />
The hazard distances for various radiation intensities are shown in table 6.4<br />
TABLE 6.4<br />
HAZARD DISTANCES (Two Tanks on fire - scenario)<br />
FO Quantity: 2 x 35 m 3<br />
Radiation intensity<br />
HAZARD DISTANCES<br />
37.5 kw/m 2 (100% lethality) 3 m<br />
25.0 kw/m 2 (50% lethality) 6 m<br />
12.5 kw/m 2 (1% lethality) 11 m<br />
4.5 kw/m 2 (1 st degree burns) 17m<br />
The hazard distances for Thermal radiation are confined to the plant premises only. Hence there<br />
will not be any thermal radiation impact on outside the population due to the pool fire scenario.<br />
The thick green belt to be developed will help to further mitigate the radiation intensity level<br />
outside plant boundary.<br />

7.1.8.2 GENERAL FIRE HAZARDS WITHIN THE PROPOSED<br />
EXPANSION ACTIVITY<br />
The potential hazardous operations and processes in the system are listed below.<br />
1. Cable Galleries<br />
For containment of fire and preventing it from spreading in the cable galleries, unit wise fire<br />
barriers with self - closing fire resistant doors with minimum fire rating of approximately 90<br />
minutes are planned. The ventilation system provided in the cable galleries would be<br />
interlocked with the fire alarm system so that, in the event of a fire alarm, the ventilation system<br />
is automatically switched - off. Also to avoid spreading of fire, all cable entries / openings in<br />
cable galleries, channels, barriers etc. Will be sealed with non inflammable /fire resistant sealing<br />
material. Instrument cables will be fire Resistant low smoke type.<br />
7.1.8.3 EFFECTIVE CONTROLS<br />
Ignition sources in the vicinity. Pressurisation of buildings not having explosion - proof fittings,<br />
switching off power supply from a central place, blanket ban on smoking, proper maintenance<br />
of flame proof fittings.<br />
The thick green belt to be developed will help to mitigate the radiation intensity level outside<br />
plant boundary.<br />
7.2 DISASTER MANAGEMENT PLAN<br />
7.2.1 DISASTERS<br />
A disaster is catastrophic situation in which suddenly, people are plunged into helplessness and<br />
suffering and as a result, need protection, clothing, shelter, medical and social care and other<br />
necessities of life.<br />
Disasters can be divided into two main groups. In the first, are Disasters resulting from natural<br />
phenomena like earthquakes, volcanic eruptions, cyclones, tropical storms, floods, avalanches,<br />
landslides etc. The second group includes disastrous events occasioned by man, or by man's<br />
impact upon the environment. Examples are industrial accidents, radiation accidents, factory<br />
fires, explosions and escape of toxic gases or chemical su<strong>bs</strong>tances, river pollution, mining or<br />
other structural collapses, air, sea, rail and road transport accidents and can reach catastrophic<br />
dimensions in terms of human loss.<br />

There can be no set criteria for assessing the gravity of a disaster in the a<strong>bs</strong>tract it depends to a<br />
large extent on the physical, economic and social environment in which it occurs. What would<br />
be considered a major disaster in developing country, will be equipped to cope with the<br />
problems involved, may not mean more than temporary emergency elsewhere. However all<br />
disasters bring in their wake similar consequences that call for immediate action, whether at the<br />
local, national or international level, for the rescue and relief of the victims. This includes the<br />
search for the dead and injured, medical and social care, removal of the debris, the provision of<br />
temporary shelter for the homeless food, clothing and medical supplies, and the rapid<br />
reestablishment of essential services.<br />
7.2.2 OBJECTIVES OF DISASTER MANAGEMENT OF PLAN<br />
The disaster Management Plan is aimed to ensure safety of life, protection of environment,<br />
protection of installation, restoration of production and salvage operations in this same order of<br />
priorities. For effective implementation of Disaster Management Plan, it will be widely<br />
circulated and personnel training through rehearsals.<br />
The Disaster Management Plan would reflect the probable consequential severity of undesired<br />
event due to deteriorating conditions or through knock on effects. Further the management<br />
should be able to demonstrate that their assessment of the consequences uses good supporting<br />
evidence and based on currently available and reliable information, incident data from internal<br />
and external sources and if necessary the reports of out side agencies.<br />
To tackle the consequences of a major emergency inside the factory or immediate vicinity of the<br />
factory, a Disaster Management Plan has to be formulated and this planned emergency is called<br />
Disaster Management Plan. The objective of the Industrial Disaster Management Plan is to<br />
make use of the combined resources of the Plant and the outside services to achieve the<br />
following:<br />
− Pool fire scenario due to FO storage<br />
− Minimise damage to property and the environment.<br />
− Effect the rescue and medical treatment of causalities.<br />
− Provide for the needs of relatives.<br />
− Provide authoritative information to news media.<br />

ENVIRONMENT MANAGEMENT PLAN<br />
10.0 INTRODUCTION<br />
The major objective and benefit of utilizing <strong>Environment</strong>al Impact Assessment in project<br />
planning stage itself, is to prevent avoidable losses of environmental resources and values as a<br />
result of <strong>Environment</strong>al Management. <strong>Environment</strong>al Management includes protection /<br />
mitigation / enhancement measures as well as suggesting post project monitoring programme.<br />
<strong>Environment</strong>al management may suggest revision of project site or operation to avoid adverse<br />
impacts or more often additional project operations may have to be incorporated in the<br />
conventional operation.<br />
The industrial development in the study area needs to be intertwined with judicious utiliztion of<br />
non-renewable resources of the study area and with in the limits of permissible assimilative<br />
capacity. The assimilative capacity of the study area is the maximum amount of pollution load<br />
that can be discharged in the environment without affecting the designated use and is governed<br />
by dilution, dispersion, and removal due to physico-chemical and biological processes. The<br />
<strong>Environment</strong> Management Plant (EMP) is required to ensure sustainable development in the<br />
study area of the proposed plant site, hence it needs to be an all encompassive plan for which the<br />
proposed industry, Government, Regulating agencies like Pollution Control Board working in<br />
the region and more importantly the affected population of the study area need to extend their<br />
cooperation and contribution. It has been evaluated that the study area has not been affected<br />
adversely and is likely to get new economical fillip. The affected environmental attributes in the<br />
region are air quality, water quality, soil, land use, ecology and public health.<br />

The Management Action Plan aims at controlling pollution at the source level to the possible<br />
extent with the available and affordable technology followed by treatment measures before they<br />
are discharged.<br />
<strong>Environment</strong>al Management aims at the preservation of ecosystem by considering the pollution<br />
abatement facilities at the plant inception. In the upcoming modern steel plants, pollution<br />
abatement has become an integral part of planning and design along with Techno economic<br />
factors.<br />
10.1 MANAGEMENT DURING CONSTRUCTION PHASE<br />
<strong>Environment</strong>al pollution is inevitable during the construction phase. The project proponent<br />
should take appropriate steps to control pollution during construction phase. The following are<br />
the factors requiring control during construction phase.<br />
10.1.1 SITE PREPARATION<br />
At the time of construction there will be some quantity of soil and debris and produce unstable<br />
material. The disturbed slopes shall be well stabilized before the on set of the monsoon. The<br />
leveling operation will also involve piling up of backfill materials. Use of dust suppressant<br />
spraying to minimize fugitive dust during construction activities is recommended.<br />
10.1.2 WATER SUPPLY AND SANITATION<br />
The employees at the plant shall be provided with water for their requirement and for the<br />
construction activities. The existing shall be provided with sufficient and suitable toilet facilities<br />
to allow proper standards of hygiene. These facilities would preferably be connected to a septic<br />
tank and shall be maintained properly to have least environmental impact.<br />
10.1.3 NOISE<br />
Noise pollution is anticipated during the construction phase due to the usage of various<br />
construction equipment such as mechanical vibrator, mixers etc. The noise effect on the nearest<br />
inhabitations due to construction activity will be negligible. However, it is advisable that onsite<br />

workers working near the noise generating equipment shall be provided with noise protection<br />
devices like earplugs.<br />
10.1.4 MAINTENANCE OF VEHICLES<br />
One should be very careful in selecting the site for vehicle maintenance, so as to prevent the<br />
ground water contamination due to the spillage of oil. Both diesel and petrol engine vehicles<br />
shall be maintained properly. Unauthorized dumping of waste oil should be prohibited. Wastes<br />
should be disposed off to the CECB approved vendors.<br />
10.1.5 WASTE<br />
The solid waste shall be collected and disposed off as per norms.<br />
10.1.6 STORAGE OF HAZARDOUS MATERIAL<br />
The following hazardous materials need to be stored at the site during construction.<br />
a. Gas for welding purpose<br />
b. LDO<br />
c. Painting materials<br />
All these materials would be stored as per international safety standards.<br />
10.1.7 LAND ENVIRONMENT<br />
The proposed expansion will not create any major impact on land environment. As soon as the<br />
construction activity is over the surplus earth will be utilised to fill up low lying areas, the<br />
rubbish will be cleared and all in built surfaces will be reinstated. Appropriate vegetation will be<br />
planned and all such areas shall be landscaped. 30 acres of extensive greenbelt will be<br />
developed (inclusive of existing greenbelt) within the premises.<br />
10.2 POST CONSTRUCTION PHASE<br />
10.2.1 AIR EMISSION MANAGEMENT<br />
The main sources of dust pollution are crushing operations of raw materials (such as, Iron ore/<br />
Coal) and their transfer points. A separate dedusting system will be provided to control the dust<br />
from various material transfer points by means of suitable ducting connected to an Induced<br />

SUMMARY<br />
1. This expansion project envisages setting up of 120,000 TPA Sponge Iron, 1,62,000 TPA<br />
Ingots/ Billets, 1,05,000 TPA Rolled products, Ferro alloys of 25000 TPA and 48 MW<br />
electricity through WHRB & FBC routes. The proposed expansion will be taken-up in the<br />
existing plant premises only.<br />
2. The flue gases from the rotary kilns will be pass through Waste Heat Recovery Boiler and<br />
after heat recovery the flue gases will pass through state-of-the-art ESP to bring down the<br />
particulate matter in the exhaust gases to within 50 mg/Nm3 and will be discharged into the<br />
atmosphere through a combined stack (Twin flues) of 60 m height. The secondary fugitive<br />
emissions from the SMS will be treated in a fume extraction system and will be discharged<br />
into the atmosphere through a stack of 30 m height. The gases from the FBC boiler will be<br />
treated in an ESP to achieve < 50 mg/Nm3 and will be discharged into the atmosphere<br />
through a stack of 72 m height for effective dispersion of emissions into the atmosphere The<br />
resultant Ground Level Concentrations of SO 2 , NO X & SPM in the post expansion project<br />
scenario are within the National Ambient Air Quality Standards (NAAQS). Hence there will<br />
not be any adverse impact on air environment due to the proposed expansion project.<br />
3. Interlocking system will be provided to ESP in such a way that , when the particulate matter<br />
in the exhaust gas exceeds the norms the feed to raw material will stop and thereby no<br />
production in the unit. The unit will restarted only when the air pollution control system is<br />
able to comply with the norms.<br />
4. Energy meters will be provided to air pollution control systems to ensure continuous<br />
operation of the control systems.<br />
