1,80,000 TPA (2X20T of Furnace & Rolling Mill) to 3,60,000 TPA (4X 20 T Induction Furnace,
Rolling & Section Mill), Captive Power Plant from 4 MW to 6 MW and Waste heat recovery
boiler based Power Plant from 6 MW to 10 MW.
Although, the application is been made on 365 days of operation, the actual operable days
for sponge iron and induction furnace can be only 330 days, keeping in mind the days for
scheduled outage and maintenance. Based on the actual operability the existing
production of 66000 TPA from two DRI kilns (2X100TPD) will enhance to 1,32,000
TPA with 4 DRI kilns (4X100TPD) after expansion. Similarly the rolled product
production will enhance to 3,00,000 TPA from 4X20T IF (12 H) and 2 stands of CCM.
The captive power generation will enhance from 4 to 6 MW by complete usage of
dolchar and coal (AFBC boiler) and 6 MW to 10 MW by WHRB.
However all environmental parameter used for assessment and evaluation of impacts
are based on TOR quantities rather than actual quantifications.

Process Description: Sponge Iron
Coal based Direct Reduction Rotary Kiln Process:
The coal based direct reduction rotary kiln process was developed for converting iron
pellets directly into metallic iron without the melting of the materials. The process has
the advantage of low capital expenditure and no requirement of coking coal. The
metallic iron in this process is produced by the reduction of iron oxide below the fusion
temperature of iron ore (1535 0C) by utilizing carbonaceous material present in the non-
coking coal. As the iron ore is in direct contact with the reducing agent throughout the
reduction process, it is often termed as direct reduced iron (DRI). The reduced product
having high degree of metallization shows a „honeycomb structure‟, due to which it is
often called sponge iron.
Coal based DRI plants are flexible with respect to plant location since non-coking coal
is widely distributed in large deposits and is easy to transport. Most plants employ
reduction process which is carried out in rotary kilns. These plants use wide variety of
raw materials and non-coking coal. The quality of these materials has direct bearing on
the process as well as the product. Some plants do not use iron ore directly. These
plants use iron ore pellets in the rotary kiln. Raw material mix consisting of iron ore/

iron ore pellets, dolomite and non-coking coal is fed at the one end of the rotary kiln
and is heated by coal burners to produce DRI. The product DRI along with char
(dolchar) is taken out from the other end of the kiln. Apart from this, primary air and
secondary air are supplied to the kiln to initiate the combustion and sustain the reaction
process in the kiln.
The main raw materials for the production of DRI by the rotary kiln process are (i) Iron
pellets, (ii) non-coking coal, and (iii) dolomite in adequate proportion to scavenge the
sulphur.
Process:
This process utilizes non-coking coal as reducing agent along with lumpy grade iron ore/
iron ore pellets.
The reduction is carried out in an inclined horizontal rotary kiln, which rotates at a
predetermined speed. A temperature profile ranging from 8000
C to 10500
C is maintained
along the length of the kiln at different zones and as the material flows down due to
gravity the ore is reduced.
The hot reduced sponge iron along with semi-burnt coal, discharged from kiln is cooled in
water – cooled cylindrical rotary cooler to a temperature of 100 to 200 0
C.
The discharge from cooler consisting of sponge iron, char other contaminations are passed
on through magnetic separators so that sponge iron can be separated from other impurities.
Later the sponge iron is screened into two size fractions i.e. -3 mm & +3 mm, for further
utilization.
The Chemical Reactions involved during the process are as under.
CO2 + C= 2CO 3Fe2 O3 + CO= 2Fe3 O4 + CO2 Fe3 O4 + CO = 3 Fe O +CO2 Fe O +CO = Fe +CO2 C + H2O = CO+ H2 3Fe2 O3 + H2 = 2Fe3 O4+H2O Fe3 O4 + H2 = 3FeO +H2O Fe O+ H2 = Fe+H2O

Induction Furnace:
Induction furnace is a type of electric melting furnace which uses electric current to
melt metal. The principle of induction melting is that a high voltage electrical source
from a primary coil induces a low voltage, high current in the metal (secondary coil).
Induction heating is simply a method of transfer of the heat energy.
Medium frequency induction furnaces which are commonly used for steelmaking use
the heat produced by eddy currents generated by a high frequency alternating field. The

inductor is usually made of copper in order to limit the electric losses. The inductor is
water cooled. The furnace consists of a crucible made of a suitable refractory material
surrounded by a water cooled copper coil. In this furnace type, the charge is melted by
heat generated from an electric arc. The coil carries the high frequency current. The
alternating magnetic field produced by the high frequency current induces powerful
eddy currents in the charge resulting in very fast heating.
Electrical energy needed for heating one ton of iron to 1500 0
C is 396 kWh. In furnace
several losses takes place which increases the specific energy consumption. The losses
consists of (i) thermal losses, (ii) furnace coil losses, (iii) capacitor bank losses, (iv)
convertor losses, and (v) losses on main side transformer. The higher the losses lower is
the furnace efficiency. Thermal losses contributes maximum towards loss of energy.
The major thermal losses are (i) radiation loss from furnace top, (ii) conduction losses
from refractory lining, (iii) heat losses in cooling water of the coil, and (iv) heat carried
by the removed slag.
During the making of a heat, the furnace is constantly losing heat both to the cooling
water and by radiation from the shell and the exposed metal surface. Electrical energy is
required to be spent to substitute this heat loss. Hence longer the heat time the greater is
the furnace inefficiency.
Process:
Scrap and sponge Iron charged to Induction furnace, which slowly melts above 15300C.
After melting the material and as required for the specific type of Mild steel
composition an addition of Silico manganese, Ferro Silicon, Aluminium, Carbon and
other chemicals shall be made. After chemical analysis of the product , the final metal
will be tapped to the ladle.

Continuous casting (CC) is a method of producing an infinite solid strand from liquid
steel by continuously solidifying it as it moves through a CC machine. It is the
predominant process route in a modern steel plant which links steelmaking and hot
rolling.
The CC machines are normally named according to the strand dimensions such as billet,
bloom, and slab CC machines etc. There are also CC machines to cast rounds and other
shapes like beam blanks.
The main equipment of a CC machine constitute (i) ladle turret along with turret
weighing system and ladle cover manipulator, (ii) tundish and tundish car along with
tundish weighing system, tundish preheater and dryer, (iii) mould and mould oscillation

Rolling Mill:
Steel rolling consists of passing the material, usually termed as rolling stock, between two
rolls driven at the same peripheral speed in opposite directions (i.e. one clockwise and the
second anti-clockwise) and so spaced that the distance between them is somewhat less than
the thickness of the section entering them. In these conditions, the rolls grip the material
and deliver it reduced in thickness, increased in length and probably somewhat increased in
width. This is one of the most widely used processes among all the metal working
processes, because of its higher productivity and lower operating cost. Rolling is able to
produce a product which is having constant cross section throughout its length. Many
shapes and sections are possible to roll by the steel rolling process.

Steel sections are generally rolled in several passes, whose number is determined by the
ratio of initial input material and final cross section of finished product. The cross section
area is reduced in each pass and form and the size of the stock gradually approach to the
desired profile. Rolling accounts for about 90 % of all materials produced by metal working
process.
When manufacturing long products, it is common to use a series of rolling stands in tandem
to obtain high production rates. The stands are grouped into roughing, intermediate and
finishing stages. Typical temperature, speed, inter-stand time (time between each stand),
true strain and strain rate ranges at each stage are shown in Tab 1. Since cross-sectional area
is reduced progressively at each set of rolls, the stock moves at different speeds at each
stage of the rolling mill. A wire rod rolling mill, for example, gradually reduces the cross-
sectional area of a starting billet (e.g., 150 mm square, 10-12 meters long) down to a
finished rod (as small as 5.0 mm in diameter, 1.93 km long) at high finishing speeds (up to
120 m/sec).
Process:
The Ingots obtained are then transferred to the Rolling/Section Mill section where there is
facility for charging of Hot Ingots incorporated in the process, gives rise to a significant
saving of fuel rating in reheating furnace as well as cutting down the total retention time,
thereby making an overall savings in the fuel rate per ton of ingots/billets.
The Mild Steel Rolled Products are then cut into required length and transferred to the
cooling bed.
From cooling bed these M.S. Rolled Products, if required are transferred to the
straightening machine and ultimately for Sorting, Packing and Dispatch. No gasifier will be
used in this process

No combustion, No emission hence Eco-friendly.
Energy being put to use, which was getting wasted anyway.
Process:
Waste heat from kiln is utilized for heating the iron pellets in pre heater kiln. Thus
temperature of Iron pellets will go up to 600oC prior to entering the kiln, which leads to
decrease in coal consumption and further reduction into coal char generation. The waste
heat generated in the rotary kiln is coming to burning chamber and then pass to waste
heat recovery boiler and power is generated. Hence heat is utilized for the power
generation in the existing unit and exhuast gases is passed through ESP and then go to
atmosphere through stack.

It will be ensured that all trucks/dumper caring raw material covered by Tarpaulin.
Water Pollution
Water is required in the plant mainly for the purpose of equipment cooling, steam
generation and Dust suppuration, Water is also required for drinking, sanitary, Green Belt
Development and fire-fighting purpose.
In order to conserve water and minimize the makeup water requirement, it is proposed to
adopt re-circulating systems for equipment cooling. In re-circulating system same water
re-circulates again and again and some make up water is added for evaporation losses.
The outflow from toilets of the plant buildings shall be led to various septic tanks in
respective areas through separate drains and the run-off from them will be connected to
packed type STP.
Out of the Fresh water requirement of 1450 KLD for the existing as well as proposed

Noise Pollution
Many operations in the Sponge Iron Plant, CPP, Induction Furnaces & Rolling
Mill produce objectionable level of noise which may not be practicable to
eliminate entirely.
Noise from compressor, fans, centrifugal pumps, electrical motors etc. will be
kept in control so that the ambient noise level shall not exceed 75 dB (A) during
day time & 70 dB (A) during night time. Noise pollution control measures will
be provided in respective departments by way of providing silencers, soundproof
cubicle / covers & proper selection of less noise prone machinery and by
development of green belt.
In some areas where due to technological process, it is not feasible to bring
down the noise level within acceptable limits, personnel working in these
areas are provided with noise reduction aid such as ear muffler and also
the duration of exposure of the personnel are limited as per the norms.
Green Belt Development
The plantation and green belt development will also be taken care in the plant
and the space reserved for plantation will be more than 33% of the total plant
area. Out of the total land of 35.38 Ha (35,37,989 sqm) Ha. Nilkanth Concast
Pvt Ltd has earmarked 11.73 Ha (1,17,334 sqm) of land for development of
green belt.
Every year tree plantation is undertaken in a planned manner on a massive scale.
Most of them including species having capability of pollution control and some
of them are capable to survive in high saline conditions & low fertile soil. Soil
management is also the part of us for better use of soil within the plant premises
and out-sides as well. Extensive Plantation & grassing has been carried out to
check the erosion from various plant activities. Concast Pvt Ltd has already
planted 13,800 trees in its plant area. The detailed layout of the plant has been
prepared with indicative area of plantation for the whole plant.

14th
September, 2006, Metallurgical Industries (Ferrous & Non-Ferrous) falls under
category „A‟ which requires Environmental Clearance (EC) to be obtained from
MoEF&CC before the commencement of ground activity.
M/s. Nilkanth Concast Private Limited now has proposed to expand manufacturing of
Sponge Iron from 72,000 TPA (2 Nos. of Kiln -100 MT/Day each) to 1,44,000 TPA (4
Nos. of Kiln -100 MT/Day each), Mild Steel, Ingots, Billets, MS Rolled Products, TMT
Bars, Channel/Angle from 1,80,000 TPA (2 Nos. of 20 T capacity of induction
Furnaces, Rolling & Section Mill) to 3,60,000 TPA (4 Nos. of 20 T capacity induction
Furnaces, Rolling & Section Mill), Captive Power Plant from 4 MW to 6 MW and
Waste heat recovery boiler- Power Plant from 6 MW to 10 MW.
Although, the application is been made on 365 days of operation, the actual operable
days for sponge iron and induction furnace can be only 330 days, keeping in mind the
days for scheduled outage and maintenance. Based on the actual operability the
existing production of 66000 TPA from two DRI kilns (2X100TPD) will enhance to
1,32,000 TPA with 4 DRI kilns (4X100TPD) after expansion. Similarly the rolled
product production will enhance to 3,00,000 TPA from 4X20T IF (12 H) and 2 stands
of CCM. The captive power generation will enhance from 4 to 6 MW by complete usage
of dolchar and coal (AFBC boiler) and 6 MW to 10 MW by WHRB.

existing production of 66000 TPA from two DRI kilns (2X100TPD) will enhance to
1,32,000 TPA with 4 DRI kilns (4X100TPD) after expansion. Similarly the rolled
product production will enhance to 3,00,000 TPA from 4X20T IF (12 H) and 2 stands
of CCM. The captive power generation will enhance from 4 to 6 MW by complete usage
of dolchar and coal (AFBC boiler) and 6 MW to 10 MW by WHRB.
However all environmental parameter used for assessment and evaluation of
impacts are based on TOR quantities rather than actual quantifications.

2.2 NEED OF PROJECT
In 2018-19, India‟s crude steel capacity was 137.9 MT and production was 106.56 MT
(Provisional) as against a production of 103.13 MT in 2017-18. In 2018-19, with an
increase of 3.3% over the previous year, India has attained the position of 2nd largest
steel producer in the world, after China. The Per Capita steel consumption in India as per
2017-18 data was around 69 kg as against the world average of around 208 kg.
India is the world‟s largest producer of Direct Reduced Iron (DRI) or Sponge Iron.
During 2017-18, total production of sponge iron is reported at around 30.511 million
tonnes of which 85% are coal based plants and 15% are gas based plants.
Post-liberalization, technological profile of the Indian Steel Industry has undergone
substantial change. With setting up of new large modern steel plants based on state-of-
the-art technologies and modernization/ expansion of existing steel plants, there is a
upward trend in efficiency parameters of operation viz. productivity, energy efficiency,
environment friendliness etc.
India‟s finished steel consumption is anticipated to increase to 230 MT by 2030-31 from
90.68 MT in 2017-18. Demand would be supported by the growth in the domestic
market. The industry is witnessing consolidation of players which has led to investments
by entities from other sectors. National steel policy 2017 implemented to encourage the
industry to reach global benchmarks.

2.6 WATER REQUIREMENT [TOR 3.7]
The total water requirement for the Plant along with proposed expansion including
domestic purpose is 1450 (1293 KLD fresh water and 157 KLD recycled water.)
Requirement of water shall be met from the Gujarat Water Infrastructure Limited
(GWIL). Water drawl permission for 1.5 MLD (0.800 MLD + 0.700 MLD) is
available with the company and permission letter is attached as Annexure VIII. No
ground water source is tapped.
Water is required in the plant mainly for the purpose of cooling and in boiler. Water
is also required for gardening, domestic and dust suppression. In order to minimize
the fresh water requirement, it is proposed to adopt recirculating system after proper
treatment. Waste water from boiler and cooling will be reused for coal dump
cooling, after proper treatment in ETP. So, the fresh water requirement will be
minimized to 1293 KLD. By virtue of flow chart the optimization of water cycle is
done to minimize the water requirement.

2.9 PROJECT IMPLEMENTATION SCHEDULE
Project Implementation Concept
In order to ensure coordinated implementation within the short construction period
envisaged for the project, it will be necessary to evolve an optimal compromise
between the fully disaggregated mode and the turnkey package implementation
mode.
The proposed model has been adopted in a number of projects with considerable
success and fast ramp up. The construction schedule for the project has been drawn
up accordingly. The implementation of project schedule is given as in Bar chart as
Annexure XI
Construction Schedule
The schedule has been developed considering mostly the supply of plant and
equipment, as well as volume of work for Construction /Erection of the plant and
other local conditions at site. According to the schedule, worked out, the Sponge
Iron Plant, WHRB, Expansion of CPP, Induction Furnaces & Rolling Mill has been
planned, to be commissioned within 12 months from the date of placement of order
for the main plant.

PECS, Nagpur Page | 58
Site development activities such as contour survey, soil investigation, site
preparation, site drainage, construction water, construction power, construction
storage yards etc. are already developed. Establishment of construction power, water
site preparation and other activities will be completed in three (3) months from „go-
ahead‟.
Special efforts will have to be made during implementation to keep the earthwork
and the site preparation to the minimum both for cost savings as well as reduction in
construction time.
Civil & Structural Work
The schedule for carrying out the civil work and structural steel work is based on the
volume of work and interlink between the completions of some of these activities to
enable the subsequent activities to proceed. Structural steelwork covers all the
building structures. In order to meet the overall time-frame envisaged in the
schedule, the completion of civil and structural work in a time-bound manner is a
pre-requisite for the project completion for the schedule.
Equipment Manufacture & Delivery
As indicated earlier, as an advance action, enquiries will have to be issued for the
various plant and equipment, on a global basis, tenders evaluated and orders
finalized. Major packages will cover material handling system, Sponge Iron Plant,
WHRB and Induction Furnaces and these will need to be tendered out. Placement of
order for such packages is envisaged within two (2) months to seven (7) months
from the date of go ahead for project construction. It is assumed that advance work
on the preparation of specifications, evaluation of tenders and readiness for
placement of orders will be taken parallel. The duration generally accepted
internationally for manufacture and delivery of various equipment have been taken
into account while evolving the implementation schedule.
Equipment Erection
Erection of equipment will have to commence after availability of fronts on
completion of the civil and structural work as well as delivery of equipment at the
plant site. It is expected that the duration for erection of equipment for the various
plant facilities will vary between Six (6) months to Eight (8) months from the date of
commencement of equipment erection.

The various off site facilities such as external water supply, external power supply
and rail & Road transportation links, Sea links etc are already available.
Trial Runs & commissioning
Commissioning work will be done after completion of Erection work. A period of 6
months has been envisaged for carrying out commissioning work and trial runs.
Project Monitoring
At the project implementation stage, all project activities from design and
engineering to construction, equipment supply, erection, testing and commissioning
of the plant and equipment will be monitored on the basis of a computerized network
monitoring system. Various reports as relevant for different aspects of project
monitoring will be generated through the computerized system.
Action points will be identified agency-wise and actions taken for timely
implementation the milestones to be achieved for meeting this schedule will be
identified and monitored for their achievement. Critical activities of the project as
they arise will also be identified and monitored and followed up to ensure timely
completion.

Total costs of the Proposed Expansion project will be Rs. 60.00 Crore with Rs. 4.0
Crore as a capital cost for Pollution Control Equipment & EMP and Rs. 0.6 Crores
will be spent for CER activities.
2.10 PROCESS DESCRIPTION
2.10.1 Sponge Iron [TOR 3.8]
The Sponge Iron shall be produced from 4 x 100 TPD Rotary Kilns. (Existing 2 x 100
TPD & Proposed 2 x 100 TPD)
Coal based Direct Reduction Rotary Kiln Process:
The coal based direct reduction rotary kiln process was developed for converting
iron pellets directly into metallic iron without the melting of the materials. The
process has the advantage of low capital expenditure and no requirement of coking
coal. The metallic iron in this process is produced by the reduction of iron oxide
below the fusion temperature of iron pellet (1535 0C) by utilizing carbonaceous
material present in the non-coking coal. As the iron pellet is in direct contact with
![Page 87: ENVIRONMENTAL IMPACT ASSESSMENT/ ENVIRONMENTAL …environmentclearance.nic.in/writereaddata/EIA/...Coc. Co 44-ordinates (lat long) of all four corners of the site. -ordinates (lat](https://reader034.vdocuments.us/reader034/viewer/2022042305/5ed0cb1de17b7f29292e6154/html5/thumbnails/87.jpg)

the reducing agent throughout the reduction process, it is often termed as direct
reduced iron (DRI). The reduced product having high degree of metallization shows
a „honeycomb structure‟, due to which it is often called sponge iron.
Coal based DRI plants are flexible with respect to plant location since non-coking
coal is widely distributed in large deposits and is easy to transport. Most plants
employ reduction process which is carried out in rotary kilns. These plants use wide
variety of raw materials and non-coking coal. The quality of these materials has
direct bearing on the process as well as the product. Some plants do not use iron
pellet directly. These plants use iron pellet pellets in the rotary kiln. Raw material
mix consisting of iron pellet, dolomite and non-coking coal is fed at the one end of
the rotary kiln and is heated by coal burners to produce DRI. The product DRI along
with char (sometimes called dolchar) is taken out from the other end of the kiln.
Apart from this, primary air and secondary air are supplied to the kiln to initiate the
combustion and sustain the reaction process in the kiln.
The main raw materials for the production of DRI by the rotary kiln process are (i)
Iron pellets, (ii) non-coking coal, and (iii) dolomite in adequate proportion to
scavenge the sulphur.
Process:
This process utilizes non-coking coal as reducing agent along with lumpy grade iron
pellets.
The reduction is carried out in an inclined horizontal rotary kiln, which rotates at a
predetermined speed. A temperature profile ranging from 8000
C to 10500
C is
maintained along the length of the kiln at different zones and as the material flows
down due to gravity the ore is reduced.
The hot reduced sponge iron along with semi-burnt coal, discharged from kiln is
cooled in water – cooled cylindrical rotary cooler to a temperature of 100 to 200 0
C.
The discharge from cooler consisting of sponge iron, char other contaminations are
passed on through magnetic separators so that sponge iron can be separated from other
impurities.
Later the sponge iron is screened into two size fractions i.e. -3 mm & +3 mm, for
further utilization. The process flow chart of ferro alloys is given in the Figure 2.6

2.10.2 Mild Steel (Ingots, Billets, TM Bars & Channel/ Angles)
Mild Steel shall be produced from 4 x 20 T Induction Furnaces (Existing 2 x 20 T &
proposed 2 x 20 T).
Induction Furnace:
Induction furnace is a type of electric melting furnace which uses electric current to
melt metal. The principle of induction melting is that a high voltage electrical source
from a primary coil induces a low voltage, high current in the metal (secondary
coil). Induction heating is simply a method of transfer of the heat energy.
![Page 90: ENVIRONMENTAL IMPACT ASSESSMENT/ ENVIRONMENTAL …environmentclearance.nic.in/writereaddata/EIA/...Coc. Co 44-ordinates (lat long) of all four corners of the site. -ordinates (lat](https://reader034.vdocuments.us/reader034/viewer/2022042305/5ed0cb1de17b7f29292e6154/html5/thumbnails/90.jpg)

Medium frequency induction furnaces which are commonly used for steelmaking
use the heat produced by eddy currents generated by a high frequency alternating
field. The inductor is usually made of copper in order to limit the electric losses. The
inductor is water cooled. The furnace consists of a crucible made of a suitable
refractory material surrounded by a water cooled copper coil. In this furnace type,
the charge is melted by heat generated from an electric arc. The coil carries the high
frequency current. The alternating magnetic field produced by the high frequency
current induces powerful eddy currents in the charge resulting in very fast heating.
Electrical energy needed for heating one ton of iron to 1500 0
C is 396 kWh. In
furnace several losses takes place which increases the specific energy consumption.
The losses consists of (i) thermal losses, (ii) furnace coil losses, (iii) capacitor bank
losses, (iv) convertor losses, and (v) losses on main side transformer. The higher the
losses lower is the furnace efficiency. Thermal losses contributes maximum towards
loss of energy. The major thermal losses are (i) radiation loss from furnace top, (ii)
conduction losses from refractory lining, (iii) heat losses in cooling water of the coil,
and (iv) heat carried by the removed slag.
During the making of a heat, the furnace is constantly losing heat both to the cooling
water and by radiation from the shell and the exposed metal surface. Electrical
energy is required to be spent to substitute this heat loss. Hence longer the heat time
the greater is the furnace inefficiency.
The induction furnace has the following technical advantages over electric arc furnace.
i) Low requirement on the electric grid
ii) Relatively cleaner process and lesser environ related expenditure.
iii) Higher yields
iv) Lower consumption of Ferro-alloys
v) No cost on electrodes
vi) Low operational cost of rolled steel depending on unit costs
vii) Lower space requirement
viii) Induction furnace is suitable for charging addition agents any time due to the
characteristics of the bath agitation.
ix) Has low load and no flicker disturbance

The disadvantages are
i) The requirement of minimal wall thickness of the refractory lining is having risk of
crack formation resulting in stoppage of operations.
ii) Induction furnaces puts more stringent requirement on the quality of scrap
iii) Decarburizing, desulphurizing and dephosphorizing is restricted due to refractory
wear.
iv) The non- metallic component of the charge materials is to be kept under control so
that volume of the slag remains under limit and does not have adverse effect on the
lining.
v) Compared to EAFs, Induction furnaces of very high capacities are not presently
available
Process:
Scrap and sponge Iron charged to Induction furnace, which slowly melts above
15300C. After melting the material and as required for the specific type of Mild steel
composition an addition of Silicomanganese, Ferro Silicon, Aluminium, Carbon and
other chemicals shall be made. After chemical analysis of the product , the final
metal will be tapped to the ladle.
Casting Process CCM:
Continuous casting (CC) is a method of producing an infinite solid strand from
liquid steel by continuously solidifying it as it moves through a CC machine. It is the
predominant process route in a modern steel plant which links steelmaking and hot
rolling.
The CC machines are normally named according to the strand dimensions such as
billet, bloom, and slab CC machines etc. There are also CC machines to cast rounds
and other shapes like beam blanks.
The main equipment of a CC machine constitute (i) ladle turret along with turret
weighing system and ladle cover manipulator, (ii) tundish and tundish car along with
tundish weighing system, tundish preheater and dryer, (iii) mould and mould
oscillation along with mould level control and electromagnetic stirrer, (iv) secondary
cooling consisting of strand cooling, strand containment and guiding, (v) withdrawal
and straightener, (vi) dummy bar, dummy bar parking and dummy bar disconnect

and (ix) Roller table and product discharge system.
Process:
Ladle liquid metal temperature adjustment done minimum (1620 to 1630°C) through
purging by Nitrogen gas to liquid metal. The Ladle goes to CCM then casting start
same time after made billets.

TMT Bar & Section Mill (Channel/Angle)
Rolling Mill:
Steel rolling consists of passing the material, usually termed as rolling stock, between
two rolls driven at the same peripheral speed in opposite directions (i.e. one clockwise
and the second anti-clockwise) and so spaced that the distance between them is
somewhat less than the thickness of the section entering them. In these conditions, the
rolls grip the material and deliver it reduced in thickness, increased in length and

probably somewhat increased in width. This is one of the most widely used processes
among all the metal working processes, because of its higher productivity and lower
operating cost. Rolling is able to produce a product which is having constant cross
section throughout its length. Many shapes and sections are possible to roll by the steel
rolling process.
Steel sections are generally rolled in several passes, whose number is determined by the
ratio of initial input material and final cross section of finished product. The cross
section area is reduced in each pass and form and the size of the stock gradually
approach to the desired profile. Rolling accounts for about 90 % of all materials
produced by metal working process.
When manufacturing long products, it is common to use a series of rolling stands in
tandem to obtain high production rates. The stands are grouped into roughing,
intermediate and finishing stages. Typical temperature, speed, inter-stand time (time
between each stand), true strain and strain rate ranges at each stage are shown in Tab 1.
Since cross-sectional area is reduced progressively at each set of rolls, the stock moves
at different speeds at each stage of the rolling mill. A wire rod rolling mill, for example,
gradually reduces the cross-sectional area of a starting billet (e.g., 150 mm square, 10-12
meters long) down to a finished rod (as small as 5.0 mm in diameter, 1.93 km long) at
high finishing speeds (up to 120 m/sec).

Process:
The Ingots obtained are then transferred to the Rolling/Section Mill section where there
is facility for charging of Hot Ingots incorporated in the process, gives rise to a
significant saving of fuel rating in hot charge furnace as well as cutting down the total
retention time, thereby making an overall savings in the fuel rate per ton of
ingots/billets.
The Mild Steel Rolled Products are then cut into required length and transferred to the
cooling bed.
From cooling bed these M.S.Rolled Products, if required are transferred to the
straightening machine and ultimately for Sorting, Packing and Dispatch. No gasifier
will be used in this process.

hot water based on the application requirements of the plant. The amount of steam
generators or Steam Boilers of heat transfer is controlled by the quantity of heat
available in the flue gases.
Waste Heat Recovery Boilers (WHRB) Benefits:
Highly Reliable in operation and robust in construction.
Quick Payback Returns are achieved.
One time investment with lifetime returns.
No combustion, No emission hence Eco-friendly.
Energy being put to use, which was getting wasted anyway.
Process:
Waste heat from kiln is utilized for heating the iron pellets in pre heater kiln. Thus
temperature of Iron pellets will go up to 600oC prior to entering the kiln, which leads
to decrease in coal consumption and further reduction into coal char generation. The
waste heat generated in the rotary kiln is coming to burning chamber and then pass to
waste heat recovery boiler and power is generated. Hence heat is utilized for the
power generation in the existing unit and exhuast gases is passed through ESP and
then go to atmosphere through stack.

2.11 MITIGATION MEASURES [TOR 3.6]
The pollutants in the form of solids, liquids and gases, generated from various
technological units of M/s. Nilkanth Concast Pvt. Ltd. have no hazardous effects on
the environment. Pollution of the environment not only adversely affects all life
forms, but also shortens the life of plant and equipment. This vital aspect,
therefore, has been taken into account while planning the plant and equipment and
adequate measures are being taken to limit the emission of pollutants within the
stipulations of statutory norms. Adoption of technology like recovery of dust/ash for
re-use as raw material fulfills the twin objectives of material conservation and
pollution control.
a) Air pollution
There will be two major source of air pollution in the plant, fugitive emission from
various dry material handling & transfer points and from flue gases generated from
the Sponge Iron and Induction Furnaces. The main process includes raw materials
storage, Grinding & screening, Transfer of material and product storage and
transportation.

b) Water pollution
Water is required in the plant mainly for the purpose of equipment cooling, steam
generation and Dust suppuration, Water is also required for drinking, sanitary, Green
Belt Development and fire fighting purpose.
In order to conserve water and minimize the makeup water requirement, it is
proposed to adopt re-circulating systems for equipment cooling. In re-circulating
system same water re-circulates again and again and some make up water is added
for evaporation losses.
Out of the Fresh water requirement of 1450 KLD for the existing as well as
proposed plants only 257 KLD waste water will be generated and 157 KLD will be
recirculated. Thus there shall be “Zero” discharge of the untreated effluent.

c) Noise pollution
Many operations in the Sponge Iron Plant, CPP, Induction Furnaces & Rolling Mill
produce objectionable level of noise which may not be practicable to eliminate
entirely.
Noise from compressor, fans, centrifugal pumps, electrical motors etc. will be kept in
control so that the ambient noise level shall not exceed 75 dB (A) during day time &
70 dB (A) during night time. Noise pollution control measures will be provided in
respective departments by way of providing silencers, soundproof cubicle / covers &
proper selection of less noise prone machinery and by development of green belt.
In some areas where due to technological process, it is not feasible to bring down
the noise level within acceptable limits, personnel working in these areas are
provided with noise reduction aid such as ear muffler and also the duration of
exposure of the personnel are limited as per the norms.
d) Solid Waste Management.

Ha (1,17,334sqm) of land for development of green belt.
Every year tree plantation is undertaken in a planned manner on a massive scale.
Most of them including species having capability of pollution control and some of
them are capable to survive in high saline conditions & low fertile soil. Soil
management is also the part of us for better use of soil within the plant premises and
out-sides as well. Extensive Plantation & grassing has been carried out to check the
erosion from various plant activities. Nilkanth concast Pvt Ltd has already planted
13,800 trees in its plant area.
The detailed layout of the plant has been prepared with indicative area of plantation
for the whole plant. The greenbelt is shown in the plant layout.

CHAPTER 3
DESCRIPTION OF ENVIRONMENT
3.0 Introduction
To assess environmental impacts from proposed project at a specific location, it is
essential to monitor the environmental quality prevailing in the surrounding area prior
to implementation of the proposed project. The environmental status within the impact
zone could be used for identification of significant environmental issues to be
addressed in the impact assessment study.
In order to identify and establish the extent of likely impacts, it is essential to gather
information on existing environmental quality with regard to various components of
the environment. The baseline environmental qualities of various environmental
components like air, noise, water, land, flora and fauna and socioeconomic form
important and integral part of EIA study. The baseline data forms the basis for
predicting/assessing the environmental impacts of the proposed project.
3.1 Description of Environment
Project Proponent requested the Ministry to reconsider the proposal after submission
of the revised EIA report with additional one-month baseline data by them in the 7th
meeting of the Re-constituted EAC (Industry-I) held during 29-31st May, 2019.
Accordingly baseline monitoring for additional one month has been carried out for the
month of June 2019. The base line data collected by NABL approved laboratory.
Previously, baseline data has been used for preparation of this EIA was generated
during October, November & December 2018. Recent data of June 2019 has been
used in the report Study Area:
The study area is 10 km radius from the boundary limits of the Project Site.
A key plan indicating Project Area as core zone and 10 km radius buffer zone is
shown below. The Figure 3.1 provides surface features like villages, habitation,
drainages, roads, railways etc.

The current site conditions are taken as the baseline conditions for formulation of
the EIA. Field monitoring for measuring meteorological conditions, ambient air
quality, water, soil and noise had been commenced during December to Feberuary
2016 and October 2018 to December 2018 [attached as Annexure IX ( c & b
respectively] to study the baseline environmental status for one season and one
month monitoring has been carried out for the month of June 2019 ([attached as
Annexure IX (a)] .In addition, data related to land use; socio-economic status has
been analysed based on the secondary information like district census reports and
remote sensing satellite imageries.

3.2 AIR ENVIRONMENT
SELECTION OF MONITORING STATIONS
The sources of air pollution in the region are industrial emissions, vehicular traffic,
dust arising from unpaved village roads and domestic fuel burning. The prime
objective of the baseline air quality study was to establish the existing ambient air
quality of the area. This will be useful for assessing the conformity to standards of the
ambient air quality during the operation of the proposed project.
Eight (8) numbers of monitoring stations were set up to assess the existing air quality
of the study area. The locations of the monitoring stations were based on the frequent
wind directions in order to site the stations as close as feasible to the anticipated

RESULTS & DISCUSSIONS
Statistical analysis (minimum, maximum, arithmetic mean and 98 percentile values) of
the ambient air quality in the study area for the entire three months monitoring period
(October- December 2018) and one month data(June 2019) has been done. The
following interpretation can be made on the basis of the obtained results:
Particulate Matter - 10 (PM10)
Arithmetic Mean of the 24-hourly average values of PM10 varied station-wise between
64.3µg/m3 (at Hatdi Village) to 83.4 µg/m3 (Project Site). Arithmetic Mean of the
24-hourly average values of PM10 at all locations is within the limit of 100 µg/m3 as
stipulated in the National Ambient Air Quality Standards, 2009. The value of PM10
ranges from 59.0 to 90 µg/m3. These values represent quite satisfactory condition
regarding PM10 concentration in ambient air.

PM2.5 Particulate Matter (<2.5 μm)
Arithmetic Mean of the 24-hourly average values of PM2.5 varied station-wise between
27.0 µg/m3 (at Hatadi Village) to 36.6 µg/m
3 (Project site). Arithmetic Mean of the 24-
hourly average values of PM2.5 at all locations is within the limit of 60 µg/m3,as
stipulated in the National Ambient Air Quality Standards, 2009. The value of PM2.5
ranges from 22.0 to 42.0 µg/m3. These values represent quite satisfactory condition
regarding PM2.5 concentration in ambient air.
Sulphur dioxide (SO2)
Arithmetic Mean of the 24-hourly average values of SO2 varied station-wise between
13.5µg/m3 (at HatadiVillage) to 21.1 µg/m
3 (Project Site). Arithmetic Mean of the 24-
hourly average values of SO2 at all locations is within the limit of 80 µg/m3as stipulated
in the National Ambient Air Quality Standards, 2009. The value of SO2 ranges from
11µg/m3 (at Hatadi Village) to 25 µg/m
3 (Project Site). These values represent quite
satisfactory condition regarding SO2 concentration in ambient air.
Oxides of Nitrogen (NOx)

Comparison of Data set
The existing data set collected for one month during June 2019 has been compared with
an earlier EIA report of Copper Refinery project of Adani Enterprises limited (EIA report
of Copper refinery proposal number J-11011/113/2016-IA) from the same region with
similar geophysical conditions. The Adani set of data is for post monsoon period,
whereas Nilkanth data set is for pre-monsoon. (Comparison of data set are given in
Annexure IX a). This is also to note that Nilkanth buffer area has been monitored thrice
during Dec –Feb 2015, October to December 2018 and June 2019. The comparison of
surface water and ground water between 2018 data set and one month 2019 data set has
been done. The 2018 data is for post monsoon period, whereas one month 2019 data
set is for pre-monsoon. The graphs showed the variation may be due seasonal difference.
The detailed are reported in Annexure IX (a).
The comparative analysis of one month data set are given as follows.
Ground Water
Particularly the results with higher values has been compared with the secondary data set
for a trend analysis
Based on the pH verses TDS relationship generally it is found when the pH is lower TDS
increases and alkalinity to mostly attributed by hardness parameter. The locations were
with a lower pH the TDS is also comparivetly low is because the respective sample is
away from the euchring environment and had a factor of dilution with fresh water. the
variation in hardness is correlated with alkanity and pH and the trend indicates lower
hardness is due to less impact of saline ingression which is been evident by the presence
of chlorides and sulphates with traces of fluoride and nitrate as well in the ground water
samples
The presence of fluoride as in the ground water samples are absent in the surface water
samples. The existing industry with proposed expansion has almost no release of fluoride
in solid, liquid or gaseous form and cannot attribute to the presence of fluoride in the

Surface Water
The surface water is highly impacted by the crick and is saline in nature with a pH range
between7.89 to 7.98. It indicates mild alkalinity but significant hardness is marked by
higher dissolved solids and due to the observed presence of fluorides, magnesium and
calcium oxides and sulphates. On lay ground water samples presence of fluoride is not
observed in the surface water samples due to the local stratography and lithology, iron in
dissolve form is accumulated in static water in this region for which pH is an indicator.
The lower the pH higher is concentration of Iron. It is also observed on a reduced
alkalinity the iron concentration shows increasing trend.

3.4 Noise Environment
Noise is most often and mostly defined as unwanted sound. In an environment noise
affects the health or interferes with the work zone activities of the people if the noise
levels are more than the permissible levels. Considerable noise gets generated in any
industrial situation due to operation of equipment.
At present, noise at area is produced due to multiple sources of commercial activities,
industrial activities and due to heavy movement of vehicles on the road.
Noise levels have measured at hourly intervals at eight stations N–1 to N-8 are described
at Table 3.9. Noise level measurement stations have shown in Figure – 3.7.

Parameters Measured During Monitoring
For noise levels measured over a given period of time interval, it is possible to describe
features of noise using statistical quantities. This is calculated using the percent of the
time certain levels exceeds the time interval. The notation for the statistical quantities
of noise levels is described below
i. Hourly Leq values have been computed by integrating sound level meter.
ii. Lday: As per the CPCB guidelines the day time limit is between 0600 to 2200
hours as outlined in the Ministry of Environment and Forest Notification S.O.
123 (E) dated 14/02/2000.
iii. Lnight: As per the CPCB guidelines the night time limit is between 2200 to
0600 hours as outlined in the Ministry of Environment and Forest Notification
S.O. 123 (E) dated 14/02/2000.
A noise rating developed by E P A for specification of community noise from all the
sources, is the Day-Night Sound Level (Ldn).
Ldn: It is similar to a 24 hr equivalent sound level, except that during the night time
period , which extends from 10 p.m. to 6 a.m., a 10 dB(A) weighing penalty is added to
the instantaneous sound level before computing 24 hr average. This night time penalty
is added to account for the fact that noise during night, when people usually sleep is
judged more annoying than the same noise during the day time.
Method of Monitoring
Noise level monitoring was performed March -2019. The noise levels were monitored
on working days only and Sundays and Public holidays were not monitored. During
each hour Leq were directly computed by the instrument based on the sound pressure
levels. Lday (Ld), Ldn values were computed using corresponding hourly Leq of day
and night respectively. The data of the noise monitoring is given in Table 3.9.

Results
Although the noise limits are well within the noise standard for industrial as well as
residential area, the diurinal variation of noise level between day time and night time
have a greater variation in industrial and high density traffic area are in location 6 to 9
and the gap diminishes in more or less residential areas with minimum traffic
3.5 Soil Environment
Soil samples were collected at selected locations in the study area to assess the existing
soil conditions around the plant area. This will establish the baseline characteristics and
will facilitate identifying the incremental concentrations due to the project at a later
stage. The baseline characteristics, which are analyzed now, include the impact on soil
due to all the miscellaneous activities and natural soil quality. The soil quality data

Community Profile: The population is
distributed among 3420 households in the study
area. The 10 inhabited villages have a
population of 15995 comprising of 8280 males
and 7715 females. The number of females per
1000 males is 931 when compared with the
figures of the Gujarat State 919 and for the
nation 933 the study area found to be lesser than State and greater than national figures
indicating an equally composite society of male and female.
The scheduled caste population of the study area
on percentage basis is 10% of the total
population and scheduled tribe population is 2%.
Socio-Religious Groups: In the project area, the
predominant community is of Hindus. The
community is divided into several castes and
sub-castes. They are engaged in agriculture, animal husbandry, weaving and craft-
related activities. Some of them sell vegetables and work as labourers. They share
similar kind of interdependency, kinship relation and strong identity with the all
community. There is communal harmony in the region.
Literacy: The overall literacy in the
10 villages of the study area was
52.53%. The male literacy in the
study area was 61.42%as compared
with State was 85.75% in this period,
and the female literacy was 42.99%
while it was 69.68% for the State. The

3.8 Geology
3.8.1 HYDRO GEOLOGICAL STUDIES
Physiography
The predominant geomorphic units identified in the district are 1) Fluvial, 2)
Physiographically, the Kutch district can be divided into four parts, namely:
a) Central High land and the Upland in the Rann Area;
b) Central Plain in the southern part;
c) Little and Great Rann areas; and
d) Banni plains.
The mainland of Kutch is an undulating country with rugged broken ground and broad
plains and is marked by hill ranges and isolated peaks. There are three hill ranges in the
main land namely Dhinodhar, Jura and Vavar, which rise to 387 m and 274 m amsl.
The other uplands in the main land area are in Wagad area in the east forming part of
Bhachau and RaparTalukas. The Pachham, Khadir and Bela islands in the Great Rann

in the north also form highlands with maximum elevation of 458 m amsl. All the hill
ranges follow a general east-west trend.
Kutch district has about 350 km long coastline and its coastal plain is about 35-45 km
wide and attains the elevation up to 80 m amsl. The coast is generally flat and broken
by small and big creeks, viz., Kori, Boacha and Godia.
The Rann forms a unique and conspicuous landform and has been divided into the
Great Rann in the north and Little Rann in the east. The Rann mainly comprises
marshy land, salt/mud flats and is devoid of vegetation and habitation and has a very
hostile environment. The total area of Rann is about 25000 sq.km.
The extensive low lying area south west of Pachchham Island resembles Rann except
for some patches of scanty vegetation. It is known as Banni plain and covers an area of
about 2000 sq. km. About 777 sq. km of Banni plain is reported to be superior
grassland.
Physiographycally, the study area is fairly flat. Due to gentle gradient towards the sea
(Gulf of Kutch) most of the water flows in the sea within short span of time. Drainage
pattern of the Kutch district is mainly by Bharud, Kali, Suri, Khari, Mithi, Rukmavati
and BhukhiLuni, Rupen, Kankawati and Malwan rivers and its tributaries.
Drainage pattern of the study area is drained by several rivers and small tributaries,
which are of dendritic pattern which remains dry in almost all the season. The seasonal
rivers (rain fed) flowing through study area are MittiNadi (0.5 km, NE), SakraNadi
(1.5 km, E) Gulf of Kutch (4 km, S), ChhelaNadi (6.5 km, E) &RuparelNadi (6.5 km,
NE) from the project site.
Natural drainage passing through the site will be suitably trained and maintained. There
will not be any diversion.
Geology
The Pre-Cambrian granite and Aravalli rocks are reported to be exposed in a tiny hillock
i.e. “MerudaTakkar” in the northern part of great Rann.
The sedimentary rocks of marine and non-marine origin formed under different
environmental conditions during middle Jurassic to Recent period occur in the district

besides volcanic and intrusive rocks (Deccan Trap) of middle Cretaceous to lower
Eocene.
Geologically, the study area is underlain by Quaternary sediments consisting of a
succession of clay, silty clay, sand and sand mixed with gravel.
Hydrogeology
The hydrogeological studies to understand the local geology, geomorphic features,
drainage network, aquifer characteristics and yield of water. Accordingly, various
components controlling the hydrogeological regime.
Occurrence of Ground Water
The formations forming aquifer or hydrogeological units can be grouped as:
a) Mesozoic formations;
b) Deccan trap (Hard rock) as aquifer;
c) Tertiary formations; and
d) Quaternary sediments.
The ground water conditions, its occurrence and movement, hydraulic characteristics
and chemical quality aspects vary considered in each hydrogeologic group. The pre-
cambrian granite and Aravalli rocks are reported be exposed in a tiny hillock i.e.
“MerudaTakkar” in the northern part of great Rann.
Mesozoic Formations
The sediments belonging to Mesozoic period include both marine and non-marine
sedimentary formation and occupy almost 60% of the district. Patcham, Chari and
Katrol series belong to Jurassic period where as Umia or Bhuj represent lower
Cretaceous.
Patcham Series
The rocks of this series consist of yellow and greyish coloured sandstone, shale, and
fossil ferrous. Limestone and represent marine sedimentary sequence. It occupies largely
the island belt of Patcham, Khadir and Bela and small area in northern part in main land
of Kutch. The ground water occurs under water table and confined conditions in the
sandstone/shale sequence belonging to this group. The semi-consolidated sandstone

exposed in the lower reaches forms phreatic aquifer and is being developed locally for
domestic and irrigation purposes. The dug wells tapping this aquifer ranges in depth
from 10 to 24 m bgl, whereas the depth to water level during summer varies from 15 to
20 m. Their yield varies from 50 to 175 m3 /day. The quality of ground water is potable
to slightly brackish and near Rann and lower reaches while the deeper ground water is
saline. In Khadir Island, the springs have been observed at Hadibadang and Kakindiya
bet. They had about ½ lps discharges and quality of ground water was fresh at
Hadibadang and saline at Kakindiya. Exploratory borehole in this formation indicated
presence of alternating layers of shale and sandstone with minor bands of limestone
down to 150 m depths. Ground water at deeper levels is under confined conditions and
quality is saline, EC up to 9000 μs/cm. Only, shallow aquifer down to 30-35 m
constituted by feldspathic sandstone exposed in the mid-reaches hold some promise for
potable ground water in this formation.
Chari Series
The formations belonging to this formation are hard oolitic limestone, sand stone and
shale representing marine facie. This formation occurs mostly as inlier in the core of
anticlines and constitutes hilly topography. There is no ground water development in
formations belonging to Chari series because of marine nature of sediments and its
physiographic settings. Not much information is available about occurrence and
movement of ground water.
Katrol Series
The rocks belonging to this series occupy the Wagad up land and northern and central
parts of main land. It is represented by shale and sand stone sequence with minor bands
of limestone. The sandstone is generally made up of hard indurated blocks, except in
Wagad area where it is feldspathic and soft/friable at places. Ground water development
in these formations is confined to only the Wagad area falling in parts of Bhachau and
RaparTalukas.
Exploratory drilling in Wagad area has revealed presence of alternate bands of sandstone
and shale. The sandstone at shallow depth is generally soft and friable and forms aquifer

locally. The ground water in this formation occurs under phreatic to confined conditions.
The ground water development is generally through dug wells which, range in depth
from less than 10 m to about 25 m. At places, the dug-cum-bored wells are also
observed with depth of bores ranging between 25 and 60 m. Depth to water level ranges
from 10 to 30 m bgl. Yield of dug wells and dug-cum-bored wells range from 60 to 660
m3 /day. Though, the formation is hard and compact at deeper levels, at places the
ground water may occur in fractures in localized areas. Few tube wells, ranging in depth
from 40 to 140 m are observed in Wagad area tapping the fractured part of the aquifer.
The discharge of such tube wells range from 400 to 1000 lpm at drawdowns ranging from
3 to 9 m. In rest of the district, the formations belonging to Katrol Series do not from
aquifer due to hard and compact nature and geomorphological setting.
Bhuj Series
The formations belonging to the Bhuj (Umia) series form the most prolific aquifer
system in the district. This aquifer is extensively developed in central part of the district
in a belt extends from Gadhuli-Dayapar-Lakhpat area in the west to Bhachau in the east.
Lithologically the Bhuj Sandstone comprises of fine to coarse grained sandstone
interbedded with siltstone and shale. The sandstone, which mainly forms the aquifer is
soft, friable and highly porous/permeable.
The quality of ground water in general is fresh with EC 5000 μS/cm. Besides this, the
quality of the formation water is known to deteriorate with depth in underlying lower
Bhuj formations.
Ground water occurs both under phreatic and confined conditions. The unconfined of the
phreatic aquifers system in this formation extends down to a depth ranging from 20 m to
about 100 m depending on the presence of aquitards/ confining layers. The ground water
in central parts occur mainly in unconfined to semiconfined conditions whereas in the
western part, the deeper horizons within this system are under confined conditions and
free flow/auto flow conditions are also observed at places. The ground water in phreatic
system is generally developed through dug wells, dug-cum-bored wells and shallow tube
wells. However, due to excessive development and deepening of water levels, most of
the dug wells have gone dry, particularly in Bhachu-Dudhai, Anjar-Khedoi-Vidi, Kera-

Sisagadh and Deshalpur-Nakhatrana-Netra areas. In these areas, the ground water is
mainly developed through deep and medium depth tube wells ranging in depth from 80
to 250 m. These tube wells tap aquifer zones in the depth range of 40 to 220 m with
aggregate thickness of granular zones ranging from 30 to 100 m. The discharge of tube
wells range between 40 and 360 m3 /hr for drawdowns ranging between 3 and 12 m.
The piezometeric levels/water levels in Bhuj Sandstone ranges from 30 to 70 m bgl.
Deccan Trap
Deccan trap occurs as almost one continuous belt from Anjar to Lakhpat Taluka with a
lateral dislocation near the injunctions of Nakhatrana, Abdasa & Mandvitalukas. It
mainly comprises of light to dark grey basalt & dolerite as moderately extensive flows.
In the areas underlain by Deccan trap, ground water occurs in the weathered mantle and
along the interflow zones, joints and fissures. In this formation, very limited
groundwater development is observed due to poor water bearing characteristics and
highly saline ground water particularly in the central and western part. At places this
formation has limited thickness and acts only as a capping to underlying formations.
Ground water development is meagre in Deccan traps. It occurs in the weathered
portions & joints. Dug wells are 11 to 15 m deep with depth to water 5 to 9 m bgl.
Tertiary Formations
The tertiary sediments belonging to Eocene to Miocene period are of marine origin &
are largely argillaceous and calcareous in nature and do not contain arenaceous members
and thus mostly have inferior quality of formation water. However, the grey and mottled
sandstone and calcareous grits of the Manchhar series (Pliocene) form moderate aquifer
in the coastal areas between Mandvi-Mundra and parts of Abdasatalukas, where ground
water quality is moderate. However, occurrence of fluoride more than permissible limits
in the coastal tracts of Abdasataluka in general is indicative of non-acceptable quality of
ground water. The recent alluvium in the district in the coastal areas contain variable
quality of ground water.
Formations of Ranikot Series occur in parts of Mandvitaluka, fringing the southern
margin of the Deccan traps. They comprise of soft argillaceous, aluminous and
variegated shale, laterite and bauxite. There is very little ground water development in
this formation.
![Page 143: ENVIRONMENTAL IMPACT ASSESSMENT/ ENVIRONMENTAL …environmentclearance.nic.in/writereaddata/EIA/...Coc.

Supra Trappeans occur as about 9 m thick ferruginous laterite (iron cap) and aluminous
ferruginous laterite derived in situ from Deccan Trap flows in Anjar- Khedoi Region.
They locally yield very meager supplies of brackish to saline water to wells. However,
generally this formation occurs above the zone of saturation.
In Bhachau region they are as much as 76 m thick at places and locally yields small
supplies of brackish water to shallow wells.
Supra Trappeans comprising laterite, aluminous shale and lateritic clays also occur as
narrow belts overlying Bhuj Series in central parts of district. There is no ground water
development in the areas underlain by this formation.
Laki Series (Eocene)
Laki Series occurs in parts of Abdasa & Lakhpat Talukas. The formations comprise of
up to 160 m thick red & mottled clays gypsiferous, pyritiferous& carbonaceous shale
with thin seams of lignite & pockets of unconsolidated fine grained sand beds at the
bottom of the series.
The formations of this series yield very little quantities of brackish to saline water to dug
wells. Ground water occurs in confined conditions also. The confined aquifer is capable
of yielding large quantities of highly saline water.
Kirthar Series (Eocene)
Formations of Kirthar Series occur in parts of Abdasa & Lakhpat Talukas. They
comprise about 325 m thick mainly composed of Nummulitic limestone with occasional
thin beds of calcareous shale.
These formations yield very little quantities of poor quality water in wells located in low
grounds.
Nari&Gaj Series (Miocene-Oligocene)
The formations of these series occur in parts of Abdasa & Lakhpat Talukas. They
comprise of up to 640 m thick, mostly argillaceous formations composed of mottled
clays and variegated shale with thin beds of fine grained clayey sandstone and Shelly
limestone.

These formations yield very little quantities of brackish to saline water to wells. Quality
is potable in wells located near the stream courses or in the vicinity of surface water
bodies.
The sediments of Gaj Series unconformabily overlie the Bhuj Series and comprise of
grey and yellowish gypseous shale inter-bedded with fossili ferous marls. Due to poor
permeability, only limited ground water development has been possible.
Manchhar Series (Pliocene)
This formation occurs in about 259 sq.km area lying between Faradi and Bhadreshwar,
overlying the Bhuj Series unconformably and comprises of buff light grey, yellowish
clay, mottled sandstone and sandy clays with gypsum.
The mottled sandstone forms productive aquifer at places. Wells range from 7 to 24 m in
depth with depth to water 3 to 15 m bgl.
In Mundrataluka, some scope of ground water development exists. In Eastern Kutch,
(Wagad Area), there is no ground water development in this formation.
In parts of BhachauTaluka, this formation occurs as up to 60 m thick undifferentiated
massive reddish brown gypseous clay, shale, some laminated silt stone, lenses of laterite
& trap gravel, mottled sandstone and occasionally some limestone. This formation yields
meagre supplies of brackish to salty water to wells.
In Anjar-Khedoi area, the sediments of Manchar Series occur as 185 m or more thick
semi-consolidated clayey sandstone and conglomeratic sandstone. Fossili ferous
sandstone with silt stone & conglomerate. Clay shale, lime cemented conglomerate.
They yield meagre to small supplies of brackish water to wells. Locally the water is
saline.
In parts of Abdasa and LakhpatTalukas, up to 550 m thick, semi-consolidated fine to
medium grained current bedded sandstone, conglomerate, mottled clay, pink & yellow
limestone occur. They yield moderate to large quantities of potable to brackish water.
Water is highly brackish/saline near the coast. In parts of Mandvi&AbdasaTalukas these
sediments are generally extensive and have permitted moderate of ground water
development by means of dug and dug-cum-bored wells. Ground water occurs under
water table conditions down to 25 m and under confined conditions further below down
to 180 m.
Chemically the ground water has fluoride content exceeding the permissible limits of
ICMR standards at many places, i.e., around Naliya. DTW ranges from 2 to 29 m bgl
with depth of wells ranging from 8 to 90 m.
Tube wells yield about 1.5 m3 /minute for drawdowns of 12 to 21 m. Trasmisivity
ranges from 14 to 173 m2 /day. Sp. Capacity ranges between 30 & 110 lpm/day.

Quaternary Sediments
Milliolite limestone, which is white to dull grey, medium-grained limestone comprising
Milliolite Foraminifer, occurs along hill slopes and faulted plains, e.g., near Sukhpur on
the northern slopes of Khatrod range west of Adhoi, near Ler, etc. There is no ground
water development in this formation.
Alluvium occurs in channels of large ephemeral streams, & coastal tracts spread over
almost whole district. The alluvium comprises of brown loamy, kankary, silt, clays,
sand, gravel, loam &kankar with a thickness of about 6 m most of the district. However,
in southern parts of the district, i.e., in Mandvi & Mundra as well as Bhachau & Anjar
Talukas, the thickness may be considerable.
The alluvium yields small quantities of brackish water to shallow wells in
Bhachautaluka. Coarse facies may yield small to moderate supplies of brackish water to
wells in Anjar-Khedoi region. In parts of Abdasa and Lakhpattalukas, the water table is
generally below the formation. In Mandvi & Mundratalukas, the ground water
development is extensive.
There is no possibility of further ground water development east and southeast of
Lakadiya by means of deep tube wells because exploratory boreholes drilled at Lakadiya
& Kumbhariya down to 450 and 305 m bgl respectively have not met with any
promising granular zones. Between Bidada and Bhadreshwar in about 450 sq.km area
dug wells are 4 to 22 m deep with depth to water 3 to 16 m bgl. The tube wells tap
aquifers down to 129 m depth. The value of T is 27.327 m2 /day.
Between Hand and Kanmer in about 500 sq.km area, dug wells are 7 to 22 m deep with
depth to water ranging front 3 to 15 m bgl. They yield 48 to 75 m3 /day.

CHAPTER 4
ANTICIPATED IMPACTS & MITIGAITON MEASURES
4.0 INTRODUCTION
As stated in chapter 1, M/s Nilkanth Concast Pvt. Limited proposed expansion of
production capacity. In this chapter, the anticipated environmental impacts and the
proposed mitigation measures for the proposed expansion have been described.
4.1 IDENTIFICATION OF IMPACTS
Identification and prediction of impacts is the most important component in the
environmental impact assessment studies. The environmental impacts can be categorized
as either primary or secondary. Primary impacts are those, which are attributed directly
due to the project and secondary impacts are those, which are indirectly induced.
The environmental impacts have been assessed assuming that the pollution due to the
existing activities in the area where the project site has been identified and covered under
the present environmental scenario established by the monitored baseline data. During
expansion phase of proposed activities various impacts on environmental parameter will
be studied to estimate the impacts on environment and apply mitigation measures.
Several scientific techniques and methodologies are available to predict impacts of
proposed activities on physical, ecological and socio-economic environments. Such
predictions are superimposed over the baseline (Pre-project) status of environmental
quality to derive the ultimate (Post-project) scenario of environmental conditions.
4.2 ASSESSMENT OF SIGNIFICANCE OF IMPACTS
The environmental impacts may include all those that are beneficial or adverse, short or
long term (acute or chronic), temporary or permanent, direct or indirect and local or
regional. The adverse impacts may include all those leading to harm to living resources,
damage to human health, hindrance to other activities, impairment of quality for use,
reduction of amenities, damage to cultural and heritage resources, and damage to physical
structures. For each identified potential environmental impact, the associated

Nilkanth Concast Private Limited management is conscious of the continuous threat
posed by pollution to society and is committed to use best environment management
practices at planning & design stage and during expansion & operation phase. The
mitigation measures have been designed within the framework of various Central/ State
legislative and regulatory requirements on environmental and socio-economic aspects
aiming at the following:
Minimize disturbance to native flora and fauna;
Prevent air, water, soil and noise pollution;
Protect sites of historical, cultural and archaeological significance, if any;
And,
Encourage the socio-economic development.
The likely impacts of the proposed project would be:
During expansion phase; and
During operation phase.
The impacts of the proposed project and corresponding mitigation measures
designed/planned during expansion and operation phase are described in the chapter
further.
4.3 IMPACTS AND MITIGATION MEASURES DUE TO PROJECT SITING
(LOCATION)
The project site is located at Survey No. 221, Village: Vadala, Taluka: Mundra,
District: Kutch, Gujarat as shown in (Chapter 1). The total land requirement for the
project is 35.38 Ha. There will be no displacement of people including home oustees,
land oustees and landless laborers, thus R&R issue are not applicable.
As indicated earlier, there are no archaeological sites, Inter-state boundary, defence
installations or airports within 10 km periphery of the plant. The area is located in seismic
zone III and lie in moderate zone. There is no national park, WLS, Biosphere Reserve
(existing as well as proposed), critically polluted zone within 10 km of the project site.

4.4 IMPACTS AND MITIGATION MEASURES DUE TO POSSIBLE ACCIDENTS
Impacts
A major accident in an industry has the potential to cause serious injury or loss of life and
extensive damage to environment or property or serious disruption outside the plant. It
may require the assistance of outside emergency services to effectively handle the
situation. Accidents are normally caused by a number of different factors, e.g. plant
failure, human error, earthquake, vehicle crash or sabotage. An important element of risk
mitigation is emergency preparedness, which is recognizing the potential situations &
consequences and prepare the site emergency plan.
Mitigation Measures
Proper onsite and offsite emergency plans & Disaster Management Plan given in the
chapter7. In addition, various fixed installations for fire detection, Alarm and Firefighting
are available to effectively tackle the situation before the fire escalates into conflagration,
regular mock drills are conducted to check the effectiveness of the system.
4.5 IMPACTS AND MITIGATION MEASURES DUE TO PROJECT DESIGN
From Chapter 1 & 2 it can be seen that the proposed expansion of Nilkanth Concast Pvt.
Ltd. is being envisaged based on the techno-economic feasibility of technology presently
available in the country. All the technological measures have been considered to reduce
the possible air emissions, effluent generation and waste generation. Thus, the impact due
to the designing of the proposed project is not envisaged.
4.6 IMPACTS AND MITIGATION MEASURES DURING EXPANSION PHASE
During expansion phase, the following activities are considered to be important towards
development of impacts:
Piling,cutting and drilling
Erection of concrete and steel structures
Road construction
![Page 155: ENVIRONMENTAL IMPACT ASSESSMENT/ ENVIRONMENTAL …environmentclearance.nic.in/writereaddata/EIA/...Coc.

Painting and finishing
Clean up operations
Landscaping and Afforestation
Expansion phase activities will have moderate impacts on land use, demography
and socioeconomic, on-site soil and on-site noise. It could also develop minor
impacts on air and water quality and ecology, which will be contained by using
water sprinklers and noise abatement measures.
4.6.1 Impacts on Air Quality
Impact on Air Environment
During the expansion phase, dust (particulate matter) is expected to be the main pollutant
to be emitted from the haul roads, stockpiles and material handling. In this case, pollution
emission sources shall be distributed throughout the project site and will fall under the
category of area source.
Vehicular emission of SO2, NO2, CO and CO2 will add onto the air pollution. Movement
of vehicles on unpaved roads will also add onto the dust emission.
The dust generated will be fugitive in nature, which can be controlled by sprinkling of
water. The impacts will be localized in nature and the areas outside the project boundary
are not likely to have any major adverse impact with respect to ambient air quality.
Air Pollution Mitigation
There will not be any major leveling operations required as it is an expansion project.
Hence, no significant impact due to excavation activities in the area, except for civil
work and foundation of equipments is envisaged.
Ambient SOx and NOx levels will increase due to operation of expansion machinery
such as bulldozers, trucks etc. However, increase in levels of these pollutants is expected
to be insignificant since these machines will be operated intermittently. These equipment
are not stationary and would be moving from one place to other, hence there will not be
increase in concentration of emissions at a single location. Nevertheless, it will be
![Page 156: ENVIRONMENTAL IMPACT ASSESSMENT/ ENVIRONMENTAL …environmentclearance.nic.in/writereaddata/EIA/...Coc. Co 44-ordinates (lat long) of all four corners of the site. -ordinates (lat](https://reader034.vdocuments.us/reader034/viewer/2022042305/5ed0cb1de17b7f29292e6154/html5/thumbnails/156.jpg)
Environmental Impact Assessment & Environment Management Plan M/s. Nilkanth Concast Private Limited
PECS, Nagpur Page | 128
ensured that construction vehicles are properly maintained to minimize exhaust
emissions. It is necessary to control the dust emissions particularly during dry weather.
This will be achieved by regular water sprinkling all over the exposed area, at least twice
a day using truck-mounted sprinklers.
4.6.2 Impacts on Water Environment
During expansion, water will be required for expansion activities, sprinkling on
pavements for dust suppression and domestic & non domestic usages.
Impacts on Hydrology and water Use
As the expansion activities will take place inside the plant premises and it will not alter
the local drainage pattern and thus, is not expected to have any impact on the local
hydrology.
Mitigation
The sewage generated during the expansion and operation phases will be treated in the
Packaged type STP. The treated effluent will be reused for green belt development.
4.6.3 Impacts on Noise Environment
The major sources of noise during the expansion phase are vehicles and construction
equipment like dozers, scrapers, concrete mixers, cranes, pumps, compressors, pneumatic
tools, saws, vibrators etc. The operation of these equipments can generate noise levels in
the range 85-90 dB (A) near the source. These noises levels will be temporary during the
day time only hence will not have any significant impact on surrounding during
expansion phase.
Mitigation
The noise control measures during the expansion phase include provision of caps on the
expansion equipment and regular maintenance of the equipment. Equipments will be
maintained appropriately to keep the noise level within 85 dB(A). Wherever possible,
equipment will be provided with silencers and mufflers. High noise producing expansion
activities will be restricted to day time only. Greenbelt will be further strengthen.

Further, workers deployed in high noise areas will be provided with necessary protective
devices such as ear plug, ear-muffs etc. Overall, the impact of increase in noise on the
environment would be insignificant, as it will be localized and mainly confined to the
day hours.
4.6.4 Impacts on Soil and land use
All the major construction activities tend to create certain changes in the soils of the
area. However, this will take place inside the plant premises and as such, there will be
no impact on the soil condition outside the plant boundary in terms of fertility.
During storms, some of the excavated soil and construction materials such as sand etc.
would be blown up in the air and dispersed around the project site; some would also tend
to be driven into the soil and clog inter granular spaces.
Total area envisaged for the project is only 35.38 Ha which is very small as compare to
the total study area, the impacts on the land use pattern of the study area will be
negligible.
However, in order to minimize such impacts, sprinkling of water shall be done.
Preparatory activities like construction of access roads, temporary offices, and godowns,
piling, storage of construction materials etc. will be confined within the project area.
These will not generally exercise any significant impact except altering the land use
pattern of the proposed site. There will be no impact on the adjoining land.
As a result, the impact of land use would be very insignificant and any impact due to
expansion will be confined within the project area and will not hamper the land use
aspects outside.
Overall, it could be easily inferred that there will be no adverse impact on soil quality &
land use in the study area.

4.6.5 Impacts on Socio-Economic Environment
The impact of the proposed expansion plant on socio economic conditions of the study
area are expected to be positive during expansion phase.
Increase in floating population.
Increase in demand of ancillary services including public transport and other
logistics services. This will help in up-liftment of local people in terms of
economy and social welfare.
Economic up-liftment of the area.
Raising of home rents, land prices and increase in labour rates.
The local population will have employment opportunities due to the proposed
project. The local people will be preferred as laborers during the expansion phase
Local people shall be given preference for employment depending on their
qualification
The kerosene/LPG will be provided to the workers to prevent cutting of nearby
trees.
4.7 IMPACTS AND MITIGATION MEASURES DURING OPERATION PHASE
The process description including quantum of pollution loads from effluents and their
control measures has been discussed in Chapter 2- Project Description.
During the operation phase, depending upon the operating conditions, environmental
releases may occur from the plant. Environmental Emissions may be in the form of:
Air emissions
Waste water discharges
Solid waste disposal
Noise etc.

4.7.1 Impacts on Air Quality [TOR 7.1]
SPONGE IRON PLANT
The impacts on air quality due to the proposed 144,000 TPA Sponge Iron Plant have
been identified. Emissions released from the stack during operation phase will get
dispersed in the atmosphere and finally reach the ground at a specified distance from the
sources. From the proposed activities the possible environmental impact on air quality
has been envisaged.
The exhaust gases coming out of WHRB, having temperature around 150-1750 C is
taken to pollution control equipment i.e. ESP. Different industries using different
type of pollution control equipment like bag filter, scrubber and some also have
Electrostatic Precipitators (ESP) the clean gas is let out through stacks.
Rotary kiln plants have emergency stack / safety cap above the ABC of feed end
column. The safety cap is required to maintain the positive pressure inside the kiln
and avoid chances of CO related explosion. In many of the plants it is observed that
continuous black smoke was discharged from this cap. At night the flame cum
black smoke is more visible. The owners resort to this practice of discharging
untreated emissions
Raw Material Handling /Transport System
The possible pollutants are fugitive dust emissions from raw materials handling areas,
viz., loading/unloading, fuel stockyard, crushing units, etc. Raw materials will be fed to
hopper with the help of pay-loader/tipper.
Mitigation Measures
M/S Nilkanth Concast Private Limited shall provide dust suction system which
will control fugitive emission due to raw material handling. Dust suppression
system will be provided in the form of water sprinklers.
![Page 160: ENVIRONMENTAL IMPACT ASSESSMENT/ ENVIRONMENTAL …environmentclearance.nic.in/writereaddata/EIA/...Coc.

All vibrating screens and weigh feeders below the hopper, day bins etc are totally
covered to prevent leakages of dust.
All bins are totally packed and covered so that there is no chance of dust leakage.
All material transfer points are connected with dust suppression water nozzles to
avoid air pollution.
From Sponge iron plant fugitive emission will be envisaged due to accumulation
of ash on finished product surface.
Finished product before move to the finished storage yard it will be passing
through the ash suction system which controls the fugitive emission.
Use of indoor or covered stockpiles or when open-air stockpiles are unavoidable,
use water spray system, dust suppressants, windbreaks and other stockpile
management techniques.
Induction Furnace
Bag filters with Suction hood will be provided for the extraction of dust particles.
The continuous casting operation is selected for the production of billets in
induction furnace, where there is less attack on refractory lining, the changing need
drastically comes down by 87%. This process results in the low gases emission.
Mitigation Measures
Installation of Bag filters with Suction hood followed by Stack.
RE-ROLLING MILL
In the re-rolling mill particulate matters and metals arise from the transfer of
molten steel to the mold and from the cutting to the length of the product by oxy-
fuel torches during continuous casting.
Scarfing and grinding activities may generate particulate matter emissions.
Mitigation Measures
Exhaust should be fitted to filters and other relevant abatement equipment,
especially in the casting, rolling, and finishing shops, wherever it is applicable.

POWER PLANT
Emission of fugitive dust from coal handling plant (CHP) and ash handling system will be
controlled through adequate dust suppression and/or extraction system so that the impact
will be negligible.
MITIGATION MEASURES
Minimize the height of coal drop to the stockpile
Use of water spray systems and polymer coatings to reduce the formation of
fugitive dust from coal storage
Use of bag filter or other particulate control equipment for coal dust emissions
from crushing / sizing activities.
Rationalizing transport systems to minimize the generation and transport of dust
on site.
Dust suppression system by water sprinkler at dump hopper of coal
Regular dust suppression with water sprinkler at transfer points;
Control of fugitive emissions from the ash pond through maintaining a permanent
blanket of water cover over the deposited ash
Green belt development and afforestation in the plant and surroundings of ash
disposal area.
The following measures will be adopted for the control of emissions from the stacks
Suitably designed ESP with efficiency of 99.89% will be placed downstream of
the stacks which will separate out the incoming dust in flue gas and limit the dust
concentration at its designed outlet concentration of 50 mg/Nm3.
For the effective dilution and dispersion of the pollutants stack height has been
proposed based on the CPCB guidelines.

The dust generated from coal handling plant will be insignificant because of
handling of fine coal is in closed circuit. For further suppression of dust adequate
water spray system will be provided;
Adequate thickness of insulating material with proper fastening will be provided
to control the thermal radiation;
The impacts on air quality due to source of the air pollution in the proposed facilities
have been identified.
Sources of Emissions
Emissions released from the stack during operation phase will get dispersed in the
atmosphere and finally reach the ground at a specified distance from the sources. From
the proposed activities the possible environmental impact on air quality has been
envisaged due to the following sources:
Raw Material Handling
The possible pollutants are fugitive dust emissions from raw materials handling areas viz.
loading / unloading, fuel stockyard, crushing units etc. The major sources of pollution
from proposed units can be classified under the following heads:
Pollutants in the waste gases namely, particulate matter (PM), sulphur dioxide,
NOX and Carbon monoxide, etc.
Fugitive dust generated during vehicular movement.
Mitigation Measures
Pollution equipment consists of I.D. fan, bag filter unit, ducting pipes, spark
arrester, pulse jet, dust collector.
M/s. Nilkanth Concast Pvt. Ltd. shall provide dust suction system which will
control fugitive emission due to material and raw material handling.
Dust suppression system will be provided in the form of water sprinklers.
All vibrating screens and weigh feeders below the hopper; day bins etc are totally
covered to prevent leakages of dust.

All bins are packed and covered so that there is no chance of dust leakage.
Regular monitoring of air polluting concentrations, etc.
Installation of Bag Filters, ESP and wet scrubbers followed by Stack
In this case the source emission is envisaged in operation phase Stacks of desired
height (12 stacks in existing & 6 stacks is proposed) for proper dispersion of
gases. Details of APCS is given in the Table 4.2.
Whenever, APCS is not working, then raw material feed will be stopped.
Consequently there will be no production in the unit till APCS is rectified.
Methodology: Impact Assessment in Air Environment [TOR 7.1]
As soon as the pollutants are emitted into the atmosphere, the dilution and dispersion of
the pollutants starts which are controlled by various meteorological parameters like wind
speed and direction, ambient temperature, etc. In most dispersion models the relevant
atmospheric layer is that nearest to the ground, varying in thickness from several hundred
to a few thousand meters. Variations in both thermal and mechanical turbulence and in
wind velocity are greatest in the layer in contact with the surface. The atmospheric
dispersion modeling and the prediction of ground level pollutant concentrations has great
relevance in the following activities:
Estimation of impact of industry on surrounding environment.
Estimation of maximum ground level concentration and its location in the
study area.
The mathematical model used for predictions on air quality impact in the present study
area is AERMOD. It is the next generation air dispersion model.
The AERMOD is actually a modeling system with three separate components:
AERMOD (AERMIC Dispersion Model), AERMAP (AERMOD Terrain Preprocessor),
and AERMET (AERMOD Meteorological Preprocessor).
Special features of AERMOD include its ability to treat the vertical in homogeneity of
the planetary boundary layer special treatment of surface releases, irregularly-shaped area

sources, a plume model for the convective boundary layer, limitation of vertical mixing
in the stable boundary layer, and fixing the reflecting surface at the stack base.
The AERMET is the meteorological preprocessor for the AERMOD. Input data can
come from hourly cloud cover observations, surface meteorological observations and
twice-a-day upper air soundings. Output includes surface meteorological observations
and parameters and vertical profiles of several atmospheric parameters.
The AERMAP is a terrain preprocessor designed to simplify and standardize the input of
terrain data for the AERMOD.

Discussion on Modelling Results
For prediction of the impacts for any proposed project, in general, the emission
contributions from the proposed units is added to existing background AAQ
concentration and the resultant AAQ expected is predicted.
The predicted ground level concentrations obtained when superimposed on the baseline
concentrations are within the prescribed NAAQ Standards for residential areas.
In point source emissions, the stacks are subjected to plume rise which again is dependent
on force of buoyancy and momentum. The higher is the plume rise or stack, the lesser
will be ground level concentrations (GLC’s).The emissions when released into the
atmosphere are subjected to transportation, dispersion, transformation, and fall out and
wash out and finally reach the ground level at a particular distance.

4.7.2 IMPACTS DUE TO THE TRANSPORTATION OF RAW MATERIAL
The emissions due to transportation of vehicles in the study area were determined from
fuel-based emission factors and number of vehicles plying on roads in the area. Loading
and transportation of raw materials are the significant sources of emissions.
The majority of trucks (95%) plying in the study area are manufactured in India as per the
standard norms hence it is assumed that emission from these trucks will be similar and
is mandatory for the vehicle manufactures to follow emission norms under the Motor
Vehicle Act. The emissions through transportation are assessed based on Emission
factors for on-road vehicles (CPCB Publication 1998).
Mitigation Measures
The vehicles transporting raw materials will be covered by tarpaulin in order to
prevent dust emission during the transport.
The vehicles used in transportation will comply norms as per the motor vehicle
act.
The repair and maintenance of vehicle will be taken care by transporter
Vehicles with PUC will be only allowed to operate
The finished product will be transported by the same trucks carrying raw material.
Green belt shall be provided around the plant area. Plantation along the internal
roads in the plant premises will also be undertaken.
Particulate matter will be controlled below 50 mg/Nm3 by providing efficient dust
suppression and extraction system. Water spray system shall be installed in the
material handling system transfer points.

Overall impacts are rated as:
Impact Rating Ambient Air Quality
Nature of impact Adverse
Duration of impact Long term
Impacted Area Localized
Likelihood of occurrence High
Severity of impact Low
Significance of impact Minor
As the maximum 24 hourly average incremental GLC values for PM, SOx and NOx due
to operation of proposed expansion project is minimal and within the limit prescribed in
NAAQS, impact of the above parameters on the Proposed Expansion. Further, the impact
is considered to be localized in nature after the control measures are implemented in-
place.
4.7.2.1 IMPACTS DUE TO VEHICLE MOVEMENT
Products, Raw Materials and wastes will be transported in covered trucks with
tarpaulin by road and ensured no spillage during transportation. Hence, there
will not be much fugitive dust generation during transportation of raw materials
and wastes. Site is well connected by Pucca road which is capable of absorbing
additional truck movement due to transportation. Green belt is developed on
both sides of internal road and also village road.
4.7.2.2 TRAFFIC STUDY [TOR 6.9]
The traffic studies have been conducted to know the prevailing traffic volumes on the existing
roads. It is essential to consider these details for assessing the anticipated future traffic volumes
as a part of overall impacts assessment for the project.
The variations of traffic densities depend upon the working days and time and also vary in day
and night times. In order to assess the prevailing traffic volumes on the roads, the survey was
![Page 175: ENVIRONMENTAL IMPACT ASSESSMENT/ ENVIRONMENTAL …environmentclearance.nic.in/writereaddata/EIA/...Coc.

conducted during normal working days of the week by avoiding local holidays or abnormal
situations to reflect the true picture of the traffic densities.
Methodology
Vehicle Count
The vehicles passing through the road (in both ways) were counted separately for 24
hours at one location from 06:00 hrs to 06:00 hrs next day continuously. Category-
wise vehicle counting has been done continuously and recorded in the traffic volume
count on hourly basis under respective categories.
Categorization of Traffic
The engine driven vehicles were categorized into various heads viz. Trucks/Bus, Light
Carriage Vehicles (LCV), Car/Jeep, Multi Axle Vehicles, Two/Three Wheelers and
Cycles/others. Survey was conducted during the weekdays and weekend.

Existing Traffic Scenario along Study Road
The road connects the project site to State Highway through other mediator roads. All types of vehicles
are observed during the study. Buses / Couch and in addition to Heavy Motor Vehicle are also using
this road. Since the road is not divided, the speed of moving vehicles is also less. The operating speeds
of vehicles are within the prescribed limit.
The traffic count was taken on weekdays as well as on holiday (weekend) to observe & compare the
variation on a working day with a holiday. It was found that working day traffic is slightly higher than
the holiday. Although the compositions of heavy vehicles like truck, etc. was found to be more or less
same for both weekdays and weekends. Accordingly the traffic data is presented for calculation and
analysis obtained for the working day.
Road safety measures will have to be practiced as it does not exist due to the absence of activities in the
area. Presently the pedestrian movement is almost negligible, however their safe movement must be
ensured during construction stage as well as after construction.
TRAFFIC MANAGEMENT MEASURES
All gates are manned with efficient security who can guide the entry and exit of vehicles.
GGL has one way traffic movement to exit gates and this ensures safety. All precautionary measures
are ensured for the safety of construction laborers while working at the site.
4.7.3 Noise Levels
During operation, the major noise generating sources are grinding mill, loading sections,
blenders etc. These sources will be located far off from each other. Under any
circumstances the noise level from each of these sources will not exceed 85 dB (A).
Noise levels generated in the project site will be confined within the proposed plant the
impact of noise levels on surrounding will be insignificant.
Mitigation Measures
The noise levels stipulated by Central Pollution Control Board at any point of time will
not exceed the standards.
By providing padding at various locations to avoid sharp noise due to vibration.
Other than the regular maintenance of the various equipment, ear plugs/muffs are

recommended for the personnel working close to the noise generating units;
All the openings like covers, partitions will be designed properly
Inlet and outlet mufflers will be provided which are easy to design and construct.
All rotating items will be well lubricated and provided with enclosures as far as
possible to reduce noise transmission.
The insulation provided for prevention of loss of heat and personnel safety will
also act as noise reducers.
4.7.4 Impact on Water
Water is required in the plant mainly for the purpose of equipment cooling, steam
generation and Dust suppuration, Water is also required for drinking, sanitary, Green
Belt Development and fire-fighting purpose.
In order to conserve water and minimize the makeup water requirement, it is proposed
to adopt re-circulating systems for equipment cooling. In re-circulating system same
water re-circulates again and again and some make up water is added for evaporation
losses.
Out of the Fresh water requirement of 1450 KLD for the existing as well as proposed
plants only 257 KLD waste water will be generated and 157 KLD will be recirculated.
Thus there shall be “Zero” discharge of the untreated effluent.
The drainage map of 5km radius of the proposed expansion project is given below:

4.7.5 Impact on soil
The reserved forests in the study area are in patches. There is no designated ecological
park or Bio Reserve/Wild life sanctuary in the 10 km radius of the proposed plant site.
The impact on terrestrial ecology will be negligible in the first instance and shall be
insignificant.

4.9.1 Irreversible and Irretrievable Commitments of Environments Component
The people are not expected to create any irreversible and Irretrievable impacts as:
The proposed expansion will be done in the existing land in which 35.38 Ha in
possession and the plant is in operation in this land, hence there is no change in the land
use pattern. No forest land is involved, no homestead involved, no land oustees and R& R
not required. All the impacts created by the project can be mitigated by adoption of
suitable mitigation measures.
Impacts Evaluation
The evaluation of the impacts of the proposed expansion on the environment, both in
terms of quality and quantity have been made. The environmental impact evaluation of
possible impacts as a result of proposed project activities on various environmental
parameters is primarily based on careful study of plant operations, surrounding
environment etc. The aspects such as air, water, land, noise and related issues of

CHAPTER 5
ANALYSIS OF ALTERNATIVES
(TECHNOLOGY & SITE)
5.0 ANALYSIS OF ALTERNATIVES (TECHNOLOGY & SITE)
Alternate technologies were explored considering the following
Capacity of the Plant.
Conservation of scarce and costly energy input.
Amenability of available raw materials.
Cost consideration.
The availability of infrastructure facilities and logistics of operation are also kept in
mind while evaluating a technology for its possible adoption.
The raw materials for Sponge Iron production are:
Iron Pellets.
Dolomite
Coal
Use of Pre-reduced iron pellets have been established as it reduces coal consumption as
well as steel scrap quantity in Induction Furnace.
Sponge pellet plant, Induction furnace, Rolling Mill and Section Mill is well known and
proven technologies all over the world. Hence, no alternative technologies are
considered.
5.1 ALTERNATE SITES/SITE SELECTION
This is an Expansion project hence no analysis of alternate site selection is required.

ENVIRONMENTAL MONITORING PROGRAMME
6.1 POST PROJECT ENVIRONMENTAL MONITORING
The environmental monitoring is important to assess performance of pollution control
equipment installed in the expansion project of M/s. Nilkanth Concast Private Limited.
The proposed project is an expansion of their 72,000 TPA Sponge Iron to 1,44,000 TPA
by Installation of additional Two no. Kilns of 100 TPD each, Mild Steel (Ingots, Billets,
TM Bars & Channel/ Angles) from 1,80,000 TPA to 3,60,000 TPA by installation of
additional two nos. of Induction furnaces 20 T capacity each, Rolling & section mill,
Captive power plant from 4MW to 6 MW and Waste Heat Recovery Power Plant
(WHRB) from 6 MW to 10 MW at Survey No.221, Village: Vadala, Taluka: Mundra,
Dist: Kutch, Gujarat. The sampling and analysis of environmental attributes including
monitoring locations will be as per the guidelines of the Central Pollution Control
Board/ State Pollution Control Board.
Environmental monitoring is being carried out on regular basis by M/s. Nilkanth
Concast Private Limited to assess the pollution level in the plant as well in the
surrounding area. Therefore, regular monitoring program of the environmental
parameters is essential to take into account the environmental pollutant of the study
area. The objective of monitoring is:
To verify the result of the impact assessment study in particular with regards to
new developments;
To follow the trend of parameters which have been identified as critical;
To check or assess the efficiency of the controlling measures;
To ensure that new parameters, other than those identified in the impact
assessment study, do not become critical due to the commissioning of proposed
facilities;
To check assumptions made with regard to the development and to detect
deviations in order to initiate necessary measures;

To establish a database for future Impact Assessment Studies for new projects.
The attributes, which needs regular monitoring, are specified below:
Air quality
Water and wastewater quality;
Noise levels;
Soil quality;
Ecological preservation and afforestation; and
Socio Economic aspects and community development
The post project monitoring to be carried out at the industry level is
discussed below:
6.2 MONITORING AND REPORTING PROCEDURE
Regular monitoring of important and crucial environmental parameters is of
immense importance to assess the status of environment during plant operation. With the
knowledge of baseline conditions, the monitoring programme can serve as an indicator
for any deterioration in environmental quality due to operation of the plant so as suitable
mitigation steps could be taken in time to safeguard the environment. Monitoring is as
important as that of control of pollution since the efficiency of control measures can only
be determined by monitoring. The following routine monitoring programme would
therefore be implemented by M/s. Nilkanth Concast Private Limited. The monitoring
schedule for the environmental parameters is suggested in Table 6.1.

7.2 RISK ASSESSMENT
Hazard analysis involves the identification and quantification of the various hazards
(unsafe conditions) that exist in the plant. On the other hand, risk analysis deals with the
identification and quantification of risks. The workers are exposed to, accidents
resulting from the hazards due to accident occur in the plant area.
Risk analysis follows an extensive hazard analysis. It involves the identification and
assessment of risks the neighbouring populations are exposed to as a result of hazards
present. This requires a thorough knowledge of failure probability, maximum credible
accident scenario, vulnerability of population etc. Consequently, the risk analysis is
often confined to maximum credible accident studies.

In the sections below, the identification of various hazards, probable risks in the
proposed plant, maximum credible accident analysis, consequence analysis are
addressed which gives a broad identification of risks involved in the plant. Based on the
risk estimation for fuel and chemical storage Disaster Management Plan (DMP) has
been prepared.
7.2.1 Approaches to the Study
Risk involves the occurrence or potential occurrence of some accidents consisting of an
event or sequence of events. The risk assessment study covers the following:
Identification of potential hazard areas.
Identification of representative failure cases.
Visualization of the resulting scenarios in terms of fire (thermal radiation) and
explosion.
Assess the overall damage potential of the identified hazardous events and the
impact zones from the accidental scenarios.
Assess the overall suitability of the site for hazard minimization and disaster
mitigation points of view.
Furnish specific recommendations on the minimization of the worst accident
possibilities
Preparation of broad Disaster Management Plan (DMP), On-site and Off-site
Emergency Plan, which includes Occupational and Health Safety Plan.

7.2.3 Occupational health impacts on the workers
Hazards in heat treatment include burns and scalding, mechanical hazards from steel
handling, and hazards arising from the annealing gases, including nitrogen, hydrogen and
carbon monoxide. Furnace insulation wools can expose workers to hazardous fibers.
HEAT STRESS
Hazard description
In heat treating, steel products are heated and cooled in a controlled way to change their
physical or mechanical properties without changing their shapes. Heat treating is used to
relieve stresses in the metal created during cold rolling, to improve its hardness or
strength, or to change its electromagnetic properties. Some heat treating is done by
quenching, in which heated steel is plunged into a cold bath of water or oil to rapidly cool
it. The most common heat-treating process is annealing, in which the steel is slowly
heated, maintained at temperature, then cooled. Often this takes place in a closed furnace,
using an inert gas to prevent oxidation, or a gas that conveys desired properties to the
steel.
Hazards in heat treatment include burns and scalding, mechanical hazards from steel
handling, and hazards arising from the annealing gases, including nitrogen, hydrogen and
carbon monoxide. Furnace insulation wools can expose workers to hazardous fibers.
Heat radiation around the furnace is 480 C to 55
0 C temperature near the furnace.
Mitigation Measures Proposed to Avoid the Human Health Hazards
Hazard control
The work area and the flow of material through it shall be designed so as to minimize the
possibility of worker contact with hot steel, or to scalding in the case of quenching
operations.

manufacturing plant is one that may affect several sections within it and/or may cause
serious injuries, loss of lives, extensive damage to environment or property or serious
disruption outside the plant. It will require the best use of internal resources and the use
of outside resources to handle it effectively. It may happen usually as the result of a
malfunction of the normal operating procedures. The project is in its formative stage and
detail engineering is yet to be done, so the DMP are based on the following concepts.
7.3.1 Emergency Procedure
1. The emergency preparedness team will be constituted within the organization
consisting of the senior officials from managerial level from the different department
like production, Health and Safety, Environmental, Material Handling, Security to
handle the emergency.
2. The team will meet once in three months to discuss the possible or probable causes /
instance leading to any disaster that may occur in and around the plant premises.
3. The team will assess the required resources to deal with the situation that may be
identified as above.
4. The team leader will lay down a detailed procedure or oral information to the each
member to follow in case of any impending or possible or actual disaster.

7.5 SOCIAL IMPACT ASSESSMENT
An understanding of the issues related to social, economic and cultural factors of the affected
people is very important for the sustainable development of the project. A social impact
assessment (SIA) therefore was carried out incorporating social analyses and participatory
processes into project design and implementation to make it responsive to social
development concerns. SIA also helped in enhancing the project benefits to poor and
vulnerable people while minimizing or mitigating concerns, risks and adverse impacts.
Further as the project implementation entails a large number other social issues such as influx
of labour during construction and others, a systematic assessment provided the basis to
prepare a Social Management Plan.

Objectives of the Study
The main objective of the study is to ensure that the project addresses the adverse impacts on
the livelihood of the people and that nobody is left worse off after implementation of the
project and those affected Project have access to project benefits, during project operation.
Specifically, the objectives of the study are:
To carry out a socio-economic, cultural and political/institutional analysis to identify the
project stakeholders and social issues associated with the project;
To assess the extent of asset loss and undertake the census of potential project affected
people;
To develop a Resettlement Action Plan (RAP) if any, in consultation with the affected
people and project authorities;
To develop a consultation framework for participatory planning and implementation of
proposed mitigation plan.
PROFILE OF PROJECT AREA AND PROJECT AFFECTED POPULATION
Following salient observations were recorded:
Education facilities are available in all the villages, in the form of primary and middle
schools. In some of the villages it is extended up to high schools. For higher studies, people
have to avail this facility from the nearest town.
Primary health centres and sub centres are run by the Govt. agencies catering its services to
the rural people. Roads in the surveyed villages are mostly pucca. Transportation service is
good but in some of the villages due to bad condition of roads, people have to walk 2-3 kms
to catch the bus.
Communication facilities are very poor in the villages surveyed.
Unemployment is a crucial problem. Though literacy rate is good, youths do not have
technical education to be absorbed in the industries on permanent basis.
Rehabilitation and Resettlement (R & R) Plan
The total land of M/s. Nilkanth Concast Private Limited is barren land and in possession.
There was no displacement of people. Thus R & R issues are not applicable.

CHAPTER 10
ENVIRONMENTAL MANAGEMENT PLAN
10.1 INTRODUCTION
The major objective and benefit of utilizing 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 program. 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.
It has been evaluated that the study area has not been affected adversely and is likely to
boost local economy. 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.
The Environmental Management Plan (EMP) has been prepared for the Existing and the
expansion Project of M/s. Nilkanth Concast Private Limited to minimize negative impacts
and is formed on the basis of prevailing environmental conditions and likely impacts of
this project on various environmental parameters during operation phase. This plan shall
also facilitate monitoring of environmental parameters. EMP includes scheme for proper
and scientific treatment and disposal mechanism for air, liquid and solid hazardous
pollutants. Apart from this, green belt development, safety aspect of the workers, noise
control, and fire protection are also included in the plan.
Various purposes of the environmental management plan are:
To treat and dispose of all the pollutants viz. liquid, gaseous and solid waste so as to meet
statutory requirements (Relevant Pollution Control Acts) with appropriate technology.
To support and implement development work to achieve environmental standards
and to improve the methods of environmental management.

Environmental Impact Assessment & Environment Management Plan M/s. Nilkanth Concast Private Limited
PECS, Nagpur Page | 203
To promote green-belt development and biodiversity in the surrounding area.
To encourage good working conditions for employees.
To reduce fire and accident hazards.
Budgeting and allocation of funds for environment management system.
To adopt cleaner production technology and waste minimization program.
10.2 MANAGEMENT PLAN DURING CONSTRUCTION PHASE
Environmental pollution is inevitable during the construction/ Expansion phase. The
project proponent should take appropriate steps to control pollution during construction
phase. The following are the factors requiring control during construction phase.
10.2.1 Site Preparation
Site development activities such as contour survey, soil investigation, site preparation,
site drainage, construction water, construction power, construction storage yards etc. are
already completed.
During Expansion of Sponge Iron Plant & Induction Furnaces: Particulate
matter would be the predominant pollutant affecting the air quality during the
construction phase. Dust will be generated mainly during excavation, back filling
and hauling operations along with transportation activities.
Sprinkling of water from tankers or other suitable means would be undertaken at
the construction sites for the suppression of fugitive dust.
Undesirable gaseous pollutants will be generated mostly by the traffic and use of
machineries. However, this would not lead to any tangible effect, as the expected
emission volume is low.
10.2.2 Water Supply and Sanitation
The employees at the plant shall be provided with water for their requirement and
for the construction activities. The site shall have sufficient and suitable toilet
![Page 232: ENVIRONMENTAL IMPACT ASSESSMENT/ ENVIRONMENTAL …environmentclearance.nic.in/writereaddata/EIA/...Coc. Co 44-ordinates (lat long) of all four corners of the site. -ordinates (lat](https://reader034.vdocuments.us/reader034/viewer/2022042305/5ed0cb1de17b7f29292e6154/html5/thumbnails/232.jpg)

PECS, Nagpur Page | 204
facilities to allow proper standards of hygiene. These facilities would preferably
be connected to a septic tank and shall be maintained properly to have least
environmental impact.
10.2.3 Noise
Noise pollution is anticipated during the construction phase due to the usage of
various construction equipment such as mechanical vibrator, mixers etc. The noise
effect on the nearest inhabitations due to construction activity will be negligible.
However, it is advisable that onsite workers working near the noise generating
equipment shall be provided with noise protection devices like earplugs.
10.2.4 Solid and hazardous Waste
The solid waste during construction / expansion shall be collected in collection beans
and disposed off as per norms.
The hazardous material such as welding gas, Painting material, Oil & Grease, shall be
stored at suitable designated places and empty drums of the oil and paints shall be
discarded as per norms.
10.3 MANAGEMENT PLAN DURING OPERATION PHASE
10.3.1 Air Environment
The major sources of air pollution in the plant are fugitive emission from material
handling & transfer points and gases like Carbon Dioxide, Sulphur Dioxide, Nitrogen
Oxides etc.
The installed system as well as proposed system for air pollution control provides
acceptable environment conditions in the working areas and abates air pollution in the

Average recharge of rail water annually is 69741.08 m3. The net annual recharge
of ground water is 69741.08 m3 from the plant premises. The company is having
pond having size of 12.5*10m *2.5m (L*W*D) is constructed. The collected
water is used for recharging of ground water, sprinkling and Gardening etc.. Thus,
the overall impact on water environment during expansion and operation phase of
the plant is temporary and insignificant.
10.3.3 Noise Environment
The major noise generating sources in the plant are DG sets, compressors,
Crushers, Screens etc. Acoustic enclosure will be provided to Noise enumerating
instruments. The major noise levels will be confined to the working zones of the
plant. The Leq of eight hours will be within the prescribed standards. Community
noise levels are not likely to be effected due to the proposed thick green belt
developed around the boundary areas and attenuation due to the physical barriers.
The ambient noise levels will be less than 75 dBA during day time & less than 70
dBA during night time. As the nearest habitation is about 1.5 Km. from the plant,
there will not be any adverse impact on habitations due to the propagation of
noise.
10.3.4 Green Belt Development
The plantation and green belt development will also be taken care in the plant and the
space reserved for plantation will be more than 33% (11.73Ha) of the total plant area.
Every year tree plantation is undertaken in a planned manner on a massive scale. Most
of them including species having capability of pollution control and some of them are
capable to survive in high saline conditions & low fertile soil. Soil management is also
the part of us for better use of soil within the plant premises and out-sides as well.
Extensive Plantation & grassing has been carried out to check the erosion from various
plant activities.
Adequate plantation will substantially abate the dust pollution, filter the polluted air,
reduce the noise and ameliorate the plant environment.

CHAPTER 11
SUMMARY & CONCLUSION
11.1 SUMMARY
This present proposal is for expansion of their 72,000 TPA Sponge Iron to 1,44,000
TPA by Installation of additional Two no. Kilns of 100 TPD each, Mild Steel
(Ingots, Billets, TM Bars & Channel/ Angles) from 1,80,000 TPA to 3,60,000 TPA by
installation of two nos. of Induction furnaces 20 T capacity each, Rolling & section
mill, Captive power plant from 4MW to 6 MW and Waste Heat Recovery Power
Plant (WHRB) from 6 MW to 10 MW, located at Survey No.221, Vill: Vadala ,
Taluka: Mundra, Dist: Kutch, Gujarat.
The Terms of Reference (ToRs) for the proposal were earlier prescribed by the Ministry
vide letter No. J-11011/85/2008-IA.II(I) Dated: 14th
September, 2015. Thereafter,
Ministry vide letter of even No dated 27/05/ 2016 amended the ToR dated 14/09/2015
with respect of production capacities of various units. The Public Hearing was
conducted on 20.12.2016 at 11:00 am at Project Site of M/s. Nilkanth Concast Private
Ltd. Further the validity of ToR was extended by the Ministry vide letter No. J-
11011/85/2008-IA.II(I) Dated: 01.05.2019, which is valid up to 13.09.2019.
The proposal was earlier considered by the EAC in 36th
meeting held during 9-10
October, 2018, in which the Honarable Committee that the EIA report was not as per the
generic structure prescribed and hence needs to be modified, with fresh baseline data
collected during the period OCT-DEC 2018. Based on their recommendation, the
Proposal was re-considered by the EAC in 7th meeting of the Re-constituted EAC
(Industry-I) held during 29-31st May, 2019, in which the Project Proponent withdrew the
proposal and requested the Ministry to consider the proposal after submission of the
revised EIA report with incorporation of additional one-month‟s baseline data. The
![Page 246: ENVIRONMENTAL IMPACT ASSESSMENT/ ENVIRONMENTAL …environmentclearance.nic.in/writereaddata/EIA/...Coc. Co 44-ordinates (lat long) of all four corners of the site. -ordinates (lat](https://reader034.vdocuments.us/reader034/viewer/2022042305/5ed0cb1de17b7f29292e6154/html5/thumbnails/246.jpg)

committee, in view of the aforesaid, recommended returned the proposal to the PP in the
present form.
Considering the above developments, the current site conditions are considered for the
baseline data and completion of the EIA Report. The Base Line data monitoring was
carried out during Oct-Dec 2018 and again One Month‟s data is been generated during
1st June 2019 to 30
th June 2019 for referential integrity and to be considered in this
revised EIA report.
Although, the application is been made based on 365 days of operation, the actual
operable days for sponge iron and induction furnace can be only 330 days, keeping in
mind the days for scheduled outage and maintenance. Based on the actual operability the
existing production, it will enhance to 1,32,000 TPA for Sponge Iron from 4 DRI kilns
(4X100TPD) after expansion. Similarly the rolled product production will enhance to
3,00,000 TPA from 4X20T IF (12 H) and 2 stands of CCM. The captive power
generation will enhance from 4 to 6 MW by complete usage of dolchar and coal (AFBC
boiler) and 6 MW to 10 MW by WHRB. However for all purposes in this report, all
environmental parameter used for assessment and evaluation of impacts are based
on TOR quantities rather than the actual quantifications, which is less than the
proposed quantities.
The proposed expansion project is intended to integrate the Steel Manufacturing process
with CCM to produce the final product as TMT bars. In order to utilize the solid waste
from DRI as well as the Flue Gas, Captive Power generation is optimized to consume the
waste heat as well as Dolchar in order to generate a sum of 16 MWH of power.
Further on the subject of water conservation, the industry is planning to optimize its
water consumption from 1450 KLD to 1293 KLD with recycle and reuse of waste water.
On the same line in alignment with Swachha Bharat Program, the industry shall convert
all its septic tanks to a combined STP for appropriate treatment and reuse of treated water
to tune of 36 KLD. Therefore, the industry shall operate with zero discharge norms.

Proposed expansion project will generate 395 Nos. of employment. And priority will be
given to local employment. The infrastructural and social amenities shall grow in the
region leading to regional development with enhanced livelihood support.
There will be two major source of air pollution in the plant, fugitive emission from
various dry material handling & transfer points and from flue gases generated from
Furnaces. The other source of emission is gaseous from Chimneys mainly contributed by
Raw material and Coal.
Many operations in the Sponge Iron Plant, CPP, Induction Furnaces & Rolling Mill
produce objectionable level of noise which may not be practicable to eliminate entirely.
Noise from compressor, fans, centrifugal pumps, electrical motors etc. will be kept in
control so that the ambient noise level shall not exceed 75 dB (A) during day time & 70
dB (A) during night time. Noise pollution control measures will be provided in respective
departments by way of providing silencers, soundproof cubicle / covers & proper
selection of less noise prone machinery and by development of green belt. In some areas
where due to technological process, it is not feasible to bring down the noise level
within acceptable limits, personnel working in these areas are provided with noise
reduction aid such as ear muffler and also the duration of exposure of the personnel
are limited as per the norms.
The major solid wastes for existing as well as Proposed Project are ESP and Bag filter
collected dust, Slag from steel making and Ash from CPP. The scrap generated to a tune
of 18000 TPA from the CCM is been utilized in the IF. The ash amounting to 4914 TPA
generated from the AFBC and DRI kiln are 100% utilized in the own brick
manufacturing unit. The Char from DRI is 100% consumed in the AFBC Technology for
power generation. The Slag from IF is proposed to be utilized in the land filling and road
constructions. Therefore, it not only utilizes the waste, but also reduces the storage space
and avoids any contamination to the soil and water bodies.
The plantation and green belt development will also be taken care in the plant and the
space reserved for plantation will be more than 33% of the total plant area. Out of the

total land of 35.38 Ha (35,37,989 sqm) Ha. Nilkanth concast Pvt Ltd has earmarked
11.73 Ha (1,17,334 sqm) of land for development of green belt. Every year tree
plantation is undertaken in a planned manner on a massive scale. Most of them including
species having capability of pollution control and some of them are capable to survive in
high saline conditions & low fertile soil. Soil management is also the part of us for better
use of soil within the plant premises and out-sides as well. Extensive Plantation &
grassing has been carried out to check the erosion from various plant activities. Nilkanth
concast Pvt Ltd has already planted 13,800 trees in its plant area.
11.2 CONCLUSION
It can be concluded from overall assessment of the impacts, in terms of positive and
negative effects on the various environmental components, that the project activities will
have minimum adverse effect on the surrounding environment.
The environment Health & safety Department (EHS) shall develop simplified standard
operating procedures for workers and technicians with existing safety practices and this
will be part of the induction training for all new entrants. In the existing practice the
compliance and operational issues are raised on a daily basis and resolved in the
following days in the Morning meeting. For a practice of minimization of risk, henceforth
identified issues will be recorded in the event register with appropriate solution /
resolution as derived for the same. This will not only identify issues, but with the trend of
complaint, root cause analysis done by management for a permanent resolution.
The pollutants in the form of solids, liquids and gases, generated from various
technological units of M/s. Nilkanth Concast Pvt. Ltd. have no drastic effects on the
environment. Pollution of the environment not only adversely affects all life forms, but
also shortens the life of plant and equipment. This vital aspect, therefore, has been taken
into account while planning the plant and equipment and adequate measures are being
taken to limit the emission of pollutants within the stipulations of statutory norms.
Adoption of technology like recovery of dust/ash for re-use as raw material fulfills the
twin objectives of material conservation and pollution control with sustainable growth.
