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.

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.

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.

P i o n e e r E n v i r o 1 - 4 Environmental Impact Assessment Report Laboratories & Consultants Pvt. Ltd.
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
demand for steel products is all set to scale. The report predicts a double-digit

P i o n e e r E n v i r o 1 - 9 Environmental Impact Assessment Report Laboratories & Consultants Pvt. Ltd.
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,

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.

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.

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.

P i o n e e r E n v i r o 3 - 1 1 Environmental Impact Assessment Report Laboratories & Consultants Pvt. Ltd.
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
N.R. ISPAT & POWER PRIVATE LIMITED Chapter – 3
Village: Gourmudi, Tehsil: Tamnar District: Raigarh, Chhattisgarh REIA Report for the Proposed Mini Integrated Steel Plant
P i o n e e r E n v i r o 3 - 1 2 Environmental Impact Assessment Report Laboratories & Consultants Pvt. Ltd.
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.

3.3.2 GROUND WATER QUALITY ASSESSMENT (TOR # 18)
The ground water samples have to be collected and analyzed for various parameters like pH,
Suspended Solids, Total Dissolved Solids, Temperature, Total Hardness, Calcium Hardness,
Magnesium hardness, Alkalinity, Fluoride, Chloride, Sulphates, Nitrates, Chemical Oxygen
Demand (COD) and for various heavy metals and is compared with the standards to know the
water quality. Selection of sampling locations will be generally done based on the following
factors:
i) Proximity of the industries to the site.
ii) Residential areas.
iii) Representation of project site.
Eight numbers of ground water samples from open wells / bore wells were collected from the
near by villages to assess ground water quality impacts. The ground water sampling locations
and their distances from the plant were shown in table 3.3.2. The water quality sampling
stations are shown in fig. 3.4. The ground water characteristics were shown in table Nos. 3.3.3 to
3.3.10.
All the water samples collected shows that they are suitable for potable purpose.

CHAPTER – IV
ANTICIPATED ENVIRONMENTAL
IMPACTS & MITIGATION MEASURES
4.0 INTRODUCTION
Impact prediction is a very important phenomenon in evaluating the environmentally
potential adverse impacts for any proposed industrial project. The impact prediction is
always carried out under worst possible conditions so as to mitigate or to eliminate the
environmental hazards. These predictions thus calculated are superimposed over the
baseline data to calculate the net impact on the environment after the proposed plant
comes into production.
4.1 AIR ENVIRONMENT
It is possible that increase in the background concentration of even a minor constituent of
the atmosphere may lead to significant changes in the atmospheric properties. So these
changes are essential in understanding potential climatic changes due to air pollutants.
For example under strongly stable condition, disturbances are highly damped and
mixing of pollutants is strongly suppressed. It is under such conditions that the worst air
pollution episodes have occurred.
Prediction of impacts is the most important component in the environmental impact
assessment studies. Several scientific techniques and methodologies are available to
predict impacts of developmental activities on physico, ecological and socioeconomic
environments. Such predictions are superimposed over the baseline (pre project) status
of environmental quality to derive the ultimate (post project) scenario of environmental
conditions. The prediction of impacts helps to identify the environmental management
plan required to be executed during and after commissioning the proposed plant to
minimize the adverse impacts on environmental quality.

The mathematical models are the best tools to quantitatively describe cause -effect
relationships between sources of pollution and different components of environment. In
case, mathematical models are not available or it is not possible to identify / validate
through models for particular situation, prediction could be arrived at through available
scientific knowledge and judgments.
The mathematical model used for predictions in the present study include, steady state
Gaussian Plume dispersion model designed for multiple point sources for air quality,
Wave divergence and Federal Highway Administration (FHWA) models for noise levels.
In case of water, land, biological and socio-economic environments the prediction have
been made based on available scientific knowledge and judgments.
4.1.1 IMPACT ON TOPOGRAPHY AND CLIMATE
4.1.1.1 IMPACT ON TOPOGRAPHY
The major envisaged topographical changes would be limited to the immediate vicinity
of the plant. The change in topography will be only due to man made structures like
Industrial complex and Administrative building. Similarly, it will invite positive benefi ts
in the form of land leveling and green belt development in the plant vicinity.
4.1.1.2 IMPACTS ON CLIMATE
As the temperature of the effluent gases will not be high, generally this will not cause any
thermal imbalance as extensive greenbelt will be developed within the plant premises.
However, there will be natural dispersion of heat due to unstable conditions during day
and as such there would be no significant micro / macro climatologically changes of any
consequence.
4.1.2 PREDICTION OF IMPACTS ON AIR ENVIRONMENT
It is absolutely essential to study the impacts of air pollution on its environs due to the
proposed Plant. These impacts are predicted with the help of Gaussian Mathematical
model. These models stimulate the relationship between air pollutant emissions from the
stack and the resultant impact on the air quality within the study zone. The pollutants

P i o n e e r E n v i r o 4 - 3 Environmental Impact Assessment Report Laboratories & Consultants Pvt. Ltd.
emitted into the atmosphere get diluted immediately and is transported and mixed with
the surrounding air. The basic purposes of these mathematical models are to represent
these processes mathematically. Computer models are used for predicting the Ground
Level Concentrations (GLC) for spatial variations.
In the present case, computation of 24 hour average Ground Level Concentrations are
carried out using ATDM (All Terrain Dispersion Model). This model is based on the
algorithms of two USEPA dispersion models, ISCST2 and COMPLEX 1 and also
incorporates the procedure used in POSTIT post processor to calculate the concentrations
in intermediate terrain.
ATDM is based on Guassian dispersion, which incorporates the Pasquill Gifford
dispersion parameters for estimating the horizontal cross wind and vertical dispersion.
ALL TERRAIN DISPERSION MODEL (TOR # 12)
The All Terrain Dispersion Model (ATDM) is a Gaussian Dispersion model that calculates
the concentration from point, area and volume source emissions in simple, intermediate
and complex terrain.
v For receptors located in simple terrain (terrain below stack top) ATDM uses the
dispersion algorithms from ISCST2 model.
v For receptors located in complex terrain (terrain above plume centre line). ATDM
uses the dispersion algorithm from the COMPLEX 1 model.
v For receptors located in intermediate terrain, ATDM uses both ISCST2 and
COMPLEX1 algorithms to estimate the 24 hourly average concentrations at each
receptor location and reports the larger of the two values as the calculated
concentration.
ATDM calculates the plume rise and plume and plume centre line elevation for a given
source to determine whether a receptor is located in a simple terrain, complex terrain or
in intermediate terrain w.r.t. source. Depending upon the terrain regime of the receptor,
N.R. ISPAT & POWER PRIVATE LIMITED Chapter – 4 Village: Gourmudi, Tehsil: Tamnar District: Raigarh, Chhattisgarh REIA Report for the Proposed Mini Integrated Steel Plant
P i o n e e r E n v i r o 4 - 4 Environmental Impact Assessment Report Laboratories & Consultants Pvt. Ltd.
the model then uses on of the three approaches described below to calculate the one -hour
average concentration at that receptor resulting from the emissions from the sources.
Simple Terrain
For receptors located in simple terrain (terrain below stack top), ATDM uses the
dispersion algorithms form the ISCST2 model. The ISCST2 model is a Gaussian
dispersion model that calculates concentrations using the Pasquill – Gifford dispersion
coefficients (Rural mode) and the Briggs urban dispersion coefficients (Urban mode). As
in ISCST2, ATDM accounts for the effects of building down wash.
User specified terrain stack base elevations are used in the ISCST2 dispersion calculations
according to EPA recommended approach for simple terrain. In this approach, the final
plume rise is calculated to determine the plume centerline elevation above the sea level
and this elevation is used for all downwind distances from the stack. Therefore, the
plume centerline remains parallel to sea level without regard to changes in the
underlying terrain.
Complex terrain
For receptors located in complex terrain (above plume centerline), ATDM uses the
dispersion algorithm from the COMPLEX1model. This algorithm is similar to that of the
ISCST2 model in that it uses the same Gaussian dispersion equation and plume rise
equations.
Intermediate Terrain
A receptor is said to be located in intermediate terrain if its elevation is greater that the
stack top elevation but less than that plume centreline elevation. For such receptors, EPA
recommends that both the ISCST 2 and COMPLEX dispersion algorithms be used to
estimate the 24 hourly average concentration at the receptor location and the larger of the
two values be used as the calculated concentration.

Multiple sources
When modeling multiple sources, ATDM sums the calculated one hour average
concentrations from each source to estimate the total concentration at a given receptor
location.

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

4.1.3 STACK HEIGHT CALCULATION
A) Stack height calculation for 2 x 100 TPD DRI Kilns attached to WHRB
Total coal consumption for 2 kilns : 260 TPD
Max. sulphur content in coal : 0.5% (by mass max.)
Total sulphur dioxide Emission : 260 x 1000 x 0.5 x 2 / 24 x 100
: 108.33 kg / hour
Stack height H : 14 (Q)0.3
: 14 (108.33)0.3
: 57.09 m
Hence a common stack (with twin flues) of 60 m height will be provided for effective
dispersion of pollutants into the atmosphere.
B) Stack Height calculation (Rolling mill)
FO Consumption per Rolling mill : 6.6 TPD
Sulphur content in FO : 4% (by mass, Max.)

P i o n e e r E n v i r o 4 - 9 Environmental Impact Assessment Report Laboratories & Consultants Pvt. Ltd.
SO2 emission : 6.6 X 1000 X 0.04 X 2/24
: 22 Kg/hr
Stack Height H : 14 (Q)0.3
: 14 (22)0.3 = 35.38 m
Hence a stack of 36 m height will be provided for effective dispersion of emissions into
the atmosphere.
C) Stack Height calculation (POWERPLANT- AFBC 10 MW)
No. of Boilers : 1 No. (40 TPH)
Entire dolochar generated from the plant i.e. 60 TPD will be used as fuel in FBC boiler.
The following will be the fuel requirement which represents the worst environmental
scenario.
Consumption of coal : 160 TPD
Sulphur content in coal : 0.5 % (by mass, Max.)
SO2 emission : 160 X 1000x.005 x2/24
: 66.66 Kg/hr
Stack Height, H : 14(Q)0.3
: 14 (66.66)0.3 = 49.35 m
Hence a stack of 50 m height will be provided to the FBC boiler of capacity 40 TPH for
effective dispersion of emissions into the atmosphere.
The hot waste flue gases from the DRI kilns will pass through Waste Heat Recovery
Boilers and after heat recovery the gases will be treated in state-of-the-art ESPs to bring
down the particulate emission in the exhaust gases to below 50 mg/Nm3.
The Exhaust emissions of FBC Boiler will pass through Electrostatic Precipitators (ESP) to
bring down the particulate matter to less than 50 mg/Nm3 and will be discharged into the
atmosphere through a stack of 50 m height. The stack details are shown in Table 4.1.3.

4.3 PREDICTION OF IMPACTS DUE TO NOISE
4.3.1 PREDICTION OF IMPACT DUE TO THE PROPOSED ACTIVITY
The sound pressure level generated by noise source decreases with increasing
distance from the source due to wave divergence.
An additional decrease in sound pressure level with distance from the source is
expected, due to atmospheric effect or its interaction with objects in the path of
transmission. For hemispherical sound wave propagation through homogeneous loss
free medium, one can estimate noise levels at various locations, due to different
sources using model based on first principle, as per the following equation:
Lp2 = Lp1 – 20 Log (r2/r1) - Ael.2
Where Lp1 and Lp2 are sound pressure levels at points located at distance r1 and r2
from the source and Ae1.2 is the excess attenuation due to environmental conditions.
Combined affect of all the sources then can be determined at various locations by
logarithmic addition.
It is first approximation one can assume that for all general population in the villages,
every noise source in the plane is a point source. The average equivalent sound power
level of such a point source can be estimated for different distances and directions
from hypothetical source by applying following equation:
Lp = Lw - 20 Log r – Ae – 8
Where Lw is the sound power level of the source, Lp is sound pressure level at a
distance r and Ae is environmental attenuation factor. A combined noise level Lp
(total) of all the sources at a particular place is given by:
Lp(total) = 10 Log (10Lp1/10) + 10(Lp2/10) + ---------)
Major noise generating sources were identified from the proposed activity for
prediction purposes. The major noise generating sources are turbines, boilers,
compressors, DG set. The predictions have been made to represent the worst case.
The noise levels at various distances were calculated using wave divergence model.
N.R. ISPAT & POWER PRIVATE LIMITED Chapter – 4 Village: Gourmudi, Tehsil: Tamnar District: Raigarh, Chhattisgarh REIA Report for the Proposed Mini Integrated Steel Plant
P i o n e e r E n v i r o 4 - 1 5 Environmental Impact Assessment Report Laboratories & Consultants Pvt. Ltd.
The model was run for ascertaining the areas where we could get the noise levels of 35,
45, 50,55,60,65, and considering the other noise generating sources from the plant.
Acoustic enclosures will be provided to turbines. Silencers will be provided to the
DG Set. All machinery will be manufactured keeping in view of the MOEF/OSHA
standards on Noise levels. The Ambient Noise levels will be within the standards
prescribed by MOE&F, GOI vide Notification dated 14-02-2000 under the Noise
pollution (regulation & control) Rules, 2000 i.e noise levels will be < 75 dBA during
day time & 70 dBA during night time.
4.3.2. PREDICTION OF IMPACTS ON COMMUNITY
Day and Night sound pressure levels, Ldn are often used to describe the community
noise exposure which includes 10 dBA night time penalties. As the nearest human
settlement is 1.2 Km. from the site, the impact of noise on general population would be
insignificant.
As per the WHO recommendation, there is no identified risk and damage of hearing due
to the noise levels (Leq = 8 hours) less than 75 dBA. Most of the international damage
risk criteria for hearing loss permit (Leq = 12 hours) upto 87 dBA. Further, WHO
recommendation on community noise annoyance, permits day time out door noise levels
of 55 dBA. Leq and night time outdoor noise level of 45 dBA leq to meet sleep criteria i.e.
Leq (24 hours) = 52.2. dBA and Ldn = 5.5 dBA.
4.3.3. PREDICTION OF IMPACT ON OCCUPATIONAL HEALTH
The damage risk criteria as enforced by OSHA (Occupation Safety and Health
Administration) to reduce hearing loss, stipulates that noise level upto 85 dBA are
acceptable for 8 hour working shift per day. Plant authorities will provide ear plugs to
the employees and will be enforced to be used by the employees.

4.4 PREDICTION OF IMPACTS ON LAND ENVIRONMENT
52.65 acres of land is proposed to be acquired for the proposed project. As there are no
endangered species in the vicinity of the proposed activity, there will not be any concern
for the loss of important germoplasm that needs conservation.
To control the fugitive emissions dust extraction system and dust suppression system
will be installed at all the possible dust emanating areas. All required pollution control
systems will be installed and operated to comply with the norms. Hence there will not be
any impact on nearby top soil.
There will not be any process waste water as closed circuit cooling system is
implemented in proposed plant. Hence there will not be any adverse impact on land
environment due to the proposed plant.
Solid waste generated from the plant will be disposed /utilized as per the norms. Hence
there will not be any adverse impact on land environment due to the proposed plant.
The land use pattern of the study area will certainly improve due to the proposed
activity. Land price in the area will increase and will benefit the local people. This
industry may attract some ancillary works also which will also help in improving the
land use pattern of the area.
Greenbelt is considered essential for maintaining the stability of the environment of the
area. 20 Acres of extensive greenbelt will be developed in the proposed plant.
4.5 PREDICTION OF IMPACTS DUE TO VEHICULAR MOVEMENT (TOR # 13)
All the major raw materials will be transported by railway rakes followed by covered
trucks by road. Hence there will not be much fugitive dust generation during
transportation of raw materials. Pucca road exist upto the site. The existing road is
capable of absorbing this additional truck movement. Hence there will not be generation
N.R. ISPAT & POWER PRIVATE LIMITED Chapter – 4 Village: Gourmudi, Tehsil: Tamnar District: Raigarh, Chhattisgarh REIA Report for the Proposed Mini Integrated Steel Plant
P i o n e e r E n v i r o 4 - 1 7 Environmental Impact Assessment Report Laboratories & Consultants Pvt. Ltd.
of fugitive dust during transportation of raw materials and products. Hence there will
not be any adverse impact on vehicular traffic due to the proposed plant.
4.6 PREDICTION OF IMPACTS ON SOCIO ECONOMIC ENVIRONMENT
The local areas will be benefited by way of generation of employment opportunities,
increased demand for local products and services. There will be an overall improvement
in the income level of the local people.
The project creates employment to about 100 persons once the plant is commissioned and
for 350 persons during construction stage. Priority will be given to locals for Semi-Skilled
and Unskilled jobs. With the development of this Plant there will be lot of scope for more
industrial investments which in turn will benefit the nation.
There will be a certain enhancement of educational and medical standards of people in
the study area. There will be generally positive and beneficial impacts by way of
economic impro vements, transportation, aesthetic environment and business generation.
There will be an overall upliftment of socio-economic status of people in the area. Regular
health checkups will be conducted.

ENVIRONMENTAL MONITORING PROGRAM
6.1 TECHNICAL ASPECTS
6.1.1 METHODOLOGIES
To know the effectiveness of environmental mitigation measures post project environmental
monitoring program will be strictly followed as per statutory requirement.
• The hot waste flue gases from the DRI kilns will pass through Waste Heat Recovery
Boilers and after heat recovery the gases will be treated in state-of-the-art ESPs and then
discharged into the atmosphere through a combined stack 60 m height to bring down the
particulate emission in the exhaust gases to below 50 mg/Nm3.
• The Exhaust emissions of FBC Boiler will pass through an Electrostatic Precipitator (ESP)
to bring down the particulate matter to less than 50 mg/Nm3 and will be discharged into
the atmosphere through a stack of 50 m height.
• Fumes will be evacuated directly from the Induction Furnaces through a swiveling type
of hoods with an air-cooled ducting. The fumes from LRF will be collected through a
water cooled hood and duct work. The duct carrying fumes from the Induction furnaces
will be led to the bag House by means of an ID fan. Clean gases having less than 50
mg/Nm3 of particulates will be discharged through a combined stack (with twin flues) of
30 m height for both the Induction Furnaces for effective dispersion of the emissions.

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

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

4. Coal handling plant Fire and or dust explosion
5. Coal storage Fire, spontaneous combustion
6. FO tank farms Fire
Coal Handling Plant - Dust Explosion
Coal dust when dispersed in air and ignited will explode. Crusher houses and conveyor systems
are most susceptible to this hazard. The minimum of explosive concentration of coal dust (33%
volatiles) is 50 grams/m3. Failure of dust extraction & suppression systems may lead to abnormal
conditions and increasing the concentration of coal dust to the explosive limits. The sources of
N.R. ISPAT & POWER PRIVATE LIMITED Chapter - 7 Village: Gourmudi, Tehsil: Tamnar, District: Raigarh, Chhattisgarh REIA Report for the Proposed Mini Integrated Steel Plant

ignition are incandescent bulbs, electric equipment & cables, friction & spontaneous combustion
in accumulated dust. Dust explosion may occur without any warning with maximum explosion
pressure upto 6.4 bars. Another dangerous characteristic of dust explosions is that it sets off
secondary explosions after the occurrence of initial dust explosion.
Stock pile area shall be provided with automatic garden type sprinklers for dust suppression as
well as to reduce spontaneous ignition of coal stock piles, necessary water distribution net work
will be provided for distributing water at all transfer points, crusher house, control room, etc.
A centralised control room with microprocessor based control system has been envisaged for
operation of the coal handling plant. Except locally controlled equipment like travelling tripper,
dust extraction / dust suppression / ventilation equipment, sump pumps, water distribution
system all other in line equipment will have provision for local control as well. All necessary inter
local control panels will be provided for safe and reliable operation of the Coal handling plant.
Control Measures for Coal Storage Yard
The entire quantity of coal will be stored in separate stack piles, with proper drains around to
collect washouts during the monsoon. Water sprinkling system will be installed on stocks of pile
to prevent spontaneous combustion and consequent fire hazards. The stack geometry will be
adopted to maintain minimum exposure of stock pile areas towards predominant wind direction
temperature will be monitored in the stock piles regularly to detect any at normal rise in
temperature inside the stock pile to be enabled to control the same.
7.1.7 RISK & CONSEQUENCE ANALYSIS OF FIRE
The principle objective of this study is to identify the potential hazards estimate the effects of
hazards to people both with in and outside the plant premises.
− Identification of possible failure cases of the facilities which might affect the population and
property within the plant boundary.

− Assessment of consequential effect on surrounding population, property etc., due to onset of
such failures.
− Suggest recommendations based on consequence analysis relevant to the situations.
7.1.7.1 METHODOLOGY
The hazards expected from this plant include the pool fire situation due to the leakage of FO from
the storage tank. There will be two nos. of FO storage tanks each of 20 KL capacity. The tank will
be made of Mild steel and will be provided with dyke around the tanks. The most credible failure
is due to the rupture of the pipe connecting the storage tank. The worst case can be assumed as
when the entire contents leak out into the dyke forming a pool, which may catch fire on finding
source of ignition.
FO STORAGE TANK - POOL FIRE SCENARIO
The maximum quantity of FO stored at site will be 2 x 20 m3 capacity. In the event of tank spilling
its contents through a small leakage or due to rupture of pipeline connecting the tank and on
ignition fire will ensue. As the tanks are provided with dyke, the fire will be confined within the
dyke. Threshold limit for first degree burns is 4.5 kw/m2. Based on these results it may be
concluded that the vulnerable zone in which the thermal fluxes above the threshold limit for first
degree burns (4.5 kw/m2) is restricted to 12 m.
The hazard distances for various radiation intensities are shown in table 7.2

outside plant boundary.
7.2 DISASTER MANAGEMENT PLAN
7.2.1 DISASTERS
A disaster is catastrophic situation in which suddenly, people are plunged into helplessness and
suffering and as a result, need protection, clothing, shelter, medical and social care and other
necessities of life.
Disasters can be divided into two main groups. In the first, are Disasters resulting from natural
phenomena like earthquakes, volcanic eruptions, cyclones, tropical storms, floods, avalanches,
landslides etc. The second group includes disastrous events occasioned by man, or by man's
impact upon the environment. Examples are industrial accidents, radiation accidents, factory fires,
explosions and escape of toxic gases or chemical substances, river pollution, mining or other
structural collapses, air, sea, rail and road transport accidents and can reach catastrophic
dimensions in terms of human loss.
There can be no set criteria for assessing the gravity of a disaster in the abstract it depends to a
large extent on the physical, economic and social environment in which it occurs. What would be
considered a major disaster in developing country, will be equipped to cope with the problems
involved, may not mean more than temporary emergency elsewhere. However all disasters bring
in their wake similar consequences that call for immediate action, whether at the local, national or
international level, for the rescue and relief of the victims. This includes the search for the dead
and injured, medical and social care, removal of the debris, the provision of temporary shelter for
the homeless food, clothing and medical supplies, and the rapid reestablishment of essential
services.

7.2.2 OBJECTIVES OF DISASTER MANAGEMENT OF PLAN
The disaster Management Plan is aimed to ensure safety of life, protection of environment,
protection of installation, restoration of production and salvage operations in this same order of
priorities. For effective implementation of Disaster Management Plan, it will be widely circulated
and personnel training through rehearsals.
The Disaster Management Plan would reflect the probable consequential severity of undesired
event due to deteriorating conditions or through knock on effects. Further the management
should be able to demonstrate that their assessment of the consequences uses good supporting
evidence and based on currently available and reliable information, incident data from internal
and external sources and if necessary the reports of out side agencies.
To tackle the consequences of a major emergency inside the factory or immediate vicinity of the
factory, a Disaster Management Plan has to be formulated and this planned emergency is called
Disaster Management Plan.
The objective of the Industrial Disaster Management Plan is to make use of the combined
resources of the Plant and the outside services to achieve the following:
− Pool fire scenario due to FO storage
− Minimise damage to property and the environment.
− Effect the rescue and medical treatment of causalities.
− Provide for the needs of relatives.
− Provide authoritative information to news media.
− Secure the safe rehabilitation of affected areas.
− Safeguard other people.
Initially contain and then ultimately bring the situation under the control.

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

The affected environmental attributes in the region are air quality, water quality, soil, land use,
ecology and public health.
The Management Action Plan aims at controlling pollution at the source level to the possible
extent with the available and affordable technology followed by treatment measures before they
are discharged.
Environmental Management aims at the preservation of ecosystem by considering the pollution
abatement facilities at the plant inception. In the upcoming modern steel plants, pollution
abatement has become an integral part of planning and design along with Techno economic
factors.
10.1 MANAGEMENT DURING CONSTRUCTION PHASE
Environmental pollution is inevitable during the construction phase. The project proponent
should take appropriate steps to control pollution during construction phase. The following are
the factors requiring control during construction phase.
10.1.1 SITE PREPARATION
At the time of construction there will be some quantity of soil and debris and produce unstable
material. The disturbed slopes shall be well stabilized before the on set of the monsoon. The
leveling operation will also involve piling up of backfill materials. Use of dust suppressant
spraying to minimize fugitive dust during construction activities is recommended.
10.1.2 WATER SUPPLY AND SANITATION
