1.2 PURPOSE OF ENVIRONMENTAL IMPACT ASSESSMENT REPORT
Every developmental activity invariably has some impact and more often adverse
consequence to the environment. Mankind as it is developed today cannot live
without taking up these developmental activities for his food, security or other needs.
Consequently, there is a need for harmonious developmental activities with the
environmental concern. EIA is one of the tools available with the planners to achieve
the above goal. It is desirable to ensure that the developmental options under
consideration are sustainable. Hence, the environmental consequence must be
characterized early in the project cycle and accounted for in the project design. The
objective of EIA is to foresee the potential environmental problems that would arise
out of the proposed development and address them in the project planning and
design stage. This can often prevent future liabilities and expensive consequences of
2
the project activity. The EIA process should allow for communication of this
information to:
1. Project proponent
2. The regulatory agencies
3. All stake holders and interest groups
EIA study is in particular essential for the industries causing significant environmental
impacts. Ministry of Environment and Forests (MoEF), Government of India has
issued EIA Notification dated 14-09-2006 in which guidelines are given for conduct of
EIA study and also the list of industries attracting the said notification.
The proposed industry is listed under EIA Notification dated 14-09-2006 and as
amended in December 2009 of Ministry of Environment and Forests (MoEF),
Government of India. As per this notification the industry is categorized under
Schedule 3(a), for Primary Metallurgical Industries (Ferrous & Non Ferrous) and
Category-A. As per the notification, prior Environmental Clearance (EC) from MoEF
is mandatory before establishment of this industry. Hence, the industry has to follow
due course of procedure to secure EC including application to MOEF for EC
clearance, terms of references from MOEF for conduct of EIA studies, public
hearing/consultations and deliberation of project at Expert Appraisal Committee of
MOEF. Accordingly, the project proponents have submitted prescribed application
along with pre-feasibility report to the MOEF New Delhi seeking terms of references
for conduct of EIA studies. MOEF New Delhi has deliberated the project in the 13th
EAC meeting dated 18.11.2013 and specified the TOR for conduct of EIA studies and
preparation of EIA report. Accordingly, EIA studies were conducted and the report is
prepared for submission to authorities. With EIA report and other documents the
industry has to approach KSPCB to conduct public hearing/consultations.
Final EIA report is to be prepared based on draft EIA report accommodating the
compliances to the observations made during public hearing/consultations. The
report will then be submitted to MOEF New Delhi for final environmental clearance.

1.5 IMPORTANCEOF THE PROJECT TO THE COUNTRY ®ION1.5.1 DOMESTIC STEEL DEMANDIn India, a major part of steel is consumed in engineering applications, followed by
automobiles and construction. The growth of steel, as is well known, is dependent
upon the growth of economy, industrial production and infrastructure sectors. The
automobile industry is on a growth path and this is likely to continue. The two-
wheeler, four-wheeler and commercial vehicle sector are all doing well. Therefore
demand for steel from these sectors is likely continue in future.
In India, apparent consumption of steel increased from 14.8 million tonnes in 1991-92
to 43.5 million tonnes in 2006-07. As per the National Steel Policy - 2005 of Govt. of
India, the demand-supply scenario for steel up to 2020 is as given below:
National Steel Policy of Government of India have considered growth rate of 7.3%
per annum. The actual growth of consumption during 2005-2006, according to Steel
Ministry, was 13.88%. Even if we assume a lower growth rate of 10% per annum, the
demand for the year 2014-15, it will be 97.67 million tons. In terms of crude steel, the
demand works out 105.5 million tons for 2015. Production of crude steel during 2005-
06 was 42.1 million tonnes. It can be seen from the above that demand is likely to be
more than double in the next ten years. Based on the assessment of steel market
(considering the boom in construction sector and industrial applications) and the
11
resources available to the promoters, it is recommended to set up a 0.2 Mt/yr pig iron
plant.
The domestic demand of steel is to increase 13.3% in 2011. The global steel demand
this year is expected to increase by 5.9%, according to the data made available by
the World Steel Association (WSA). India, with an expected growth in steel demand
of 13.3%, will lead the steel demand in the world.
The association (WSA), whose members produce 85% of the total steel made in the
world, in its newsletter about the ‘short range outlook’ on steel in 2011 and 2012,
said, “India is expected to show strong growth in steel use in the coming years due to
its strong domestic economy, massive infrastructure needs and expansion of
industrial production.” It further says that in 2012, India’s steel demand will touch
14.3%, reaching 79 million tonnes (mt) per year. In 2010, India produced 67 mt steel
and is the fifth-largest steelmaker in the world with China as the leader, followed by
Japan, US and Russia.
It is clear from the data that the steel demand will continue to be driven by the
growing economies, led by India. Even as the consumption is growing in the western
world, WSA predicts that by 2012, steel use in the developed world will still be at 14%
below the 2007 level whereas in the emerging and developing economies, it will be
38% above. In 2012, the emerging and developing economies will account for 72% of
world steel demand in contrast to 61% in 2007, WSA noted.
State-owned Steel Authority of India, too, is ramping up production to reach 24 million
tons from a shade under 14 million tons, currently. The capacity will come in phases
over the next little years. The demand for alloy and special steels in the country is
increasing in the last few years as the consumption of steel has increased by 12%
since year 1998. It finds major use in the forging, automobile, auto component,
railway etc. There is huge domestic demand for alloy and special steels and this
demand is likely to continue in future.
In view of the present encouraging industrial trend for use of steel in the country ,
which is likely to continue in future, M/s. SRL have proposed to expand its activity in
steel production capacity at economical cost.
12
1.5.2 DEMAND SUPPLY GAP, IMPORTS vs INDIGENOUS PRODUCTIONThe scope for raising the total consumption of steel is huge in India, given that per
capita steel consumption is only 40 kg – compared to 150 kg across the world and
250 kg in China.
The National Steel Policy has envisaged steel production to reach 110 million tons by
2019-20. However, based on the assessment of the current ongoing projects, both in
greenfield and brownfield, Ministry of Steel has projected that the steel capacity in the
county is likely to be 124.06 million tons by 2011-12. Further, based on the status of
MOUs signed by the private producers with the various State Governments, it is
expected that India’s steel capacity would be nearly 293 million tons by 2020.
India has been a net importer of steel but in recent years due to the commissioning of
capacities in the range of 8-10 million tons, we might become a net exporter.
Therefore production of steel at the regional level will be highly beneficial & help in
reduction of imports.
1.5.3 EMPLOYMENT GENERATION DUE TO THE PROJECTThe total direct employment potential during operational phase of the proposed
project is about 950 people. However, the commencement of this industry will create
indirect employment opportunities to more than 1,000 people in terms of
transportation, vehicle maintenance, petty shops etc. In addition, about 400 persons
will be employed during the construction phase of the project.
1.6 OBJECTIVE AND SCOPE OF EIA STUDIESThe overall objective of any EIA studies is to identify and assess the adverse and

1.7 METHODOLOGY OF EIA STUDIES1.7.1 EXISTING ENVIRONMENTAL STATUS
The environmental influence due to the project is likely to cover a radial
distance of about 10 km around the factory premises. Therefore, the study area for
monitoring of environmental parameters covers 10 km distance from the project site.
The environmental parameters, which are likely to be affected by the activities of the
project, were identified. They include air, noise, water, soil, land use, ecology, socio-
economics etc. The existing status of these environmental parameters for study area
14
is collected from both primary and secondary sources. Primary source data were
collected through environmental monitoring survey of representative locations of the
study area during the post monsoon period of 11th December 2013 to 11th March
2014. The reconnaissance survey was conducted and the sampling locations were
identified based on:

gas will also be established along with coke oven plant. Producer gas is used in
Reheating furnace of rolling mill. Pulverized coal injection will be used in Mini blast
furnace to decrease coke consumption.
2.1.2 INTERLINKED/INTERDEPENDENT PROJECTS
The power generated from coke oven plant is based on waste heat present in coke
oven off gas and the power generated is used only for captive consumption.
2.1.3 CATEGORIZATION OF THE PROJECT
The proposed industry is listed under EIA Notification dated 14-09-2006 and as
amended in December 2009 of Ministry of Environment and Forests (MoEF),
Government of India. As per this notification the industry is Classified under Schedule
3(a), for Primary Metallurgical Industries (Ferrous & Non Ferrous) and Category-A.
2.2 NEED (JUSTIFICATION) FOR EXPANSION OF THE INDUSTRYThe industry M/s. SLR Metaliks ltd with its present operational capacity is not
economically viable. There is huge demand for steel in the country. Further, the
Bellary region in Karnataka State is a potential zone for establishment of iron and
steel industries because of its accessibility to natural resources including water and
raw material like rich iron ore, dolomite, manganese ore etc. Establishment of the
steel industry with its own resources will meet the national interest of development
through self-realization. Further, it helps to enhance the status of this underdeveloped
rural area through improvement in roads, communication, job opportunities and other
infrastructural facilities. The Government of Karnataka envisaged the policy to
encourage iron and steel industries in the state. Hence, M/s. SLR proposes to
increase the production activity of the industry by establishing facility for manufacture
of downstream and associated products.
The expansion will be done in the vicinity of the existing premises. Administrative and
ancillary infrastructure facility will be made use of in expansion of the project. Hence,
the expansion will be achieved with minimum resources.
In these days of high competition, escalating cost of production, power and raw
materials it is essential to produce steel at economic cost. In the present industry this
20
is to be achieved by modernization of technology, value addition, recovery and use of
wastes and enhancement of capacity with minimal resources.
2.3 DESCRIPTION OF LOCATION
2.3.1 BASIS FOR SELECTION OF THE SITE
The proposed project is expansion of the existing project and therefore associated
with activities of the existing industry. The proposed steel plant will utilize the hot
metal produced in the existing pig iron plant. Similarly the coke produced from the
proposed coke oven will be utilized in the existing blast furnace. Hence, the proposed
facility is essentially to be located adjacent to the existing project site. Hence, no
alternate sites are considered.
The expansion project is proposed to be located East side of the existing industrial
premises. 90 acres of land is already allotted by KIADB for the proposed expansion
project and another 100 acres is under process by KIADB. Expansion is proposed in
the additionally allotted land for the proposed plants.
No significant change expected in land cover or topography. The proposed land is
non-agriculture, rocky, sandy, un-cultivated barren land. It does not require clearance
of existing land, vegetation or buildings. The choice of the land confers several
advantages, which are summarized below.
1. The site is connected to mines through rail-line and highways. SH- 25 is4.29 km South East from the site and NH 13 at a distance of 6.5 km East fromthe project site. Railway line is at 7.2 km NE from the site.2. Ecologically sensitive areas like forest land, national park, heritage locationetc are not in the vicinity. T.B. dam back water is at a distance of 700m to3000m from the proposed facilities depending upon the water level.3. Water has been allocated form T.B. Board by GOK.4. Housing facilities, educational facilities, recreational facilities and otheramenities are available at Hosapete located at 9.2 km NE.5. No incidence of cyclones, earth quake, floods or landslides in the region.
Considering the above, the site adjacent to the existing industry located at
Narayanadevanakere village is selected for the expansion project.

2.6.1 MANUFACTURING PROCESS FOR STEEL MILLA Steel making unit with Energy Optimizing Furnace (EOF) /LRF/VD is proposed. A
flow chart for manufacture of steel is given in Figure-2.7.
2.6.1.1. ENERGY OPTIMIZING FURNACE (EOF)The oxygen process is the most common process for producing steel. The Energy-
optimizing oxygen furnace (EOF) involves this process using combined submerged
(bottom) and atmospheric (top) blowing. The hot metal from blast furnace is taken into
the EOF, 20-22% scrap / DRI is then added into the hot metal. The necessary fluxes
32
(ferro-alloys, calcined lime and iron ore) are also added to the bath. Oxygen is blown
into the bath through water-cooled lances using combined bottom and top blowing.
During blowing operation, oxygen oxidizes iron into iron oxide and carbon into carbon
monoxide. The iron oxide immediately transfers the oxygen to the tramp elements,
which leads to formation of reactive slag. As blowing continues, there is a continuous
decrease of carbon, phosphorous, manganese and silicon within the melt. The refining
process is completed when the desired carbon content is attained. The steel is tapped
into the ladle furnace by a transfer trolley. The slag is discharged into the slag pot.
2.6.1.2. LADLE FURNACE AND VACUUM DEGASSING UNITThe ladle furnaces are used to refine steel & VD furnace helps in degassing steel and
they act as a buffer between EOF and continuous casting machine. It is utilized to
maintain high levels of steel cleanliness, de-sulfurisation and accurate temperature
control. The required temperature is maintained with the help of small electrodes, while
the melt is homogenized by introduction of inert nitrogen/argon gas. The ladle is then
lifted and taken to vacuum degassing unit. Vacuum degassing refines the molten steel
by removing unwanted hydrogen and nitrogen gases. The molten metal ladle from LF
is placed under vacuum generated by multiple stage steam ejectors. After sampling of
the steel and temperature measurement, the ladle is shifted to continuous casting
machine. The vacuum-degassing unit utilizes steam generated by a boiler (run by
furnace oil).
2.6.1.3. BILLET/BLOOM CASTERSDuring continuous casting, the refined liquid steel passes from the pouring ladle, with
the exclusion of air, via a tundish with an adjusTable discharge device (nozzles) into
the short, water-cooled mould. The shape of the mould defines the shape of the steel
i.e blooms or billets. The red-hot strand, solidified at the surface zones, is drawn from
the mould by driving rolls. Once it has completely cooled and solidified by carefully
spraying water, the strand is divided by mobile gas cutting torches. The cut pieces are
then allowed to cool and sent to stacking/ storage yard/rolling. A third strand of
casters and a strand EMS has been proposed for each of the bloom and billet casters.
This will reduce the casting time and also give better quality of blooms and billets.
33
2.6.2 MANUFACTURING PROCESS FOR ROLLING MILLSteel manufactured in the steel shop will be sent to rolling mill unit for products of
specified sizes. The process includes pre-heating in the furnace and hot rolling
followed by shot blasting, mechanical surface finishing before inspection and
stacking. A flow chart for manufacture of steel making and rolling mill is given in

2.6.3.1 COAL HANDLING AND PREPARATIONCoal from different sources will be brought to the factory site by trucks and unloaded
on to the raw material stockyard. The coal will be have moisture of around 8%,
therefore, reduces the risk of fugitive emissions. In the stock yard it will be blended to
optimum composition required for coking. After blending it will be crushed to 100%
through 1 mm by suiTable crushers. The crushed coal falls directly into the coal
charging Car and is stamped suitably. Water is the sole binder to form the coal cake.
The Charging car is of about 24 ton capacity and will move on rail tracks for charging
the ovens. The empty Car after charging is brought back to the crusher/coal bunker
for further loading of coal. The specifications of coal used in coke oven plant is given
in Table-2.7

2.6.3.2 COMPACTING STATIONDuring the Stamp Charging, the water content serves as a binder. However, the
density of stamped coal cake is about 1100 kg/m³ (wet) against 750 kg/m³ of coal in
Beehive Ovens. The increase in bulk density is about 40%. The dimension of coal
cake is slightly lesser than the opening dimension of the coke oven. It will help in
easier pushing process.
2.6.3.3 CHARGING CARThe compacted coal cake shall be freely rested on top of the charging plate in the
compacting box at the compacting station and shall be transferred from the
compacting box by transfer drive of Charging Car and thus charged into the oven.
36
When the coal cake reaches its end position inside the coke oven chamber, the
charge trestle shall hold the cake in position and the plate will be withdrawn. After
extraction of charging plate, the car shall be ready for the next charging operation.
2.6.3.4 COKE OVEN BATTERIES
It has been proposed to install two batteries of 30 Ovens each with a level coal
charge capacity of 23 to 25 tons with coking cycles of 65 to 70 hours. This will have
an annual production capacity of 1,20,000 MTPA of coke. Two sets of 30 ovens shall
be connected to a chimney.
The ovens are constructed with alumina bricks of different sizes, shapes and
specifications. The mosaic of bricks of different specification ensures that high
alumina bricks are used in the areas of oven that calls for higher and more expensive
specifications. The areas subjected to less stringent thermal requirements shall have
bricks of less expensive specifications. The capacity of coke oven battery is given in
Table-2.8.

2.6.3.5 PUSHER CARCoke pushing operation after 65 to 70 hrs cycle from oven will be done with the help
of a separate coke push car, which pushes the hot coke cake into the hot coke car.
Pusher car shall have pusher beams, which shall rest on guide rollers driven by
motor, gearbox and rack & pinion arrangement. The pusher shield, which will push
the hot coke cake from the ovens, shall be fixed to the pusher beams along with
37
vertical rollers and cold air ducts. The carriage will have four wheel bogies and each
will be driven by electric motors, gearbox, coupling and brakes. The pusher car shall
be positioned on the pusher side of the oven and the hot coke car shall be positioned
on the coking side. Coke oven doors of both sides shall be opened and the pusher
beams shall slowly push the hot coke cake from the oven to the hot coke car.
The hot coke cake pushed from the oven by the pusher shall slide into the hot coke
car at the same horizontal level to avoid potential emission arising out of coke falling
and disintegrating during the pushing operation.
2.6.3.6 HOT COKE CARThe hot coke car shall have a long travel car, which travels lengthwise along the
coking side of the coke ovens. On this trolley a hot coke tray is fixed to receive the
hot coke cake from the ovens and bring the same to the quenching tower for
quenching operations. The long travel car shall be a four wheel bogie traveling on
longitudinal rails. The four wheel bogie shall be driven by an independent drive
motor, gearbox, couplings and brakes. Hot coke tray shall be hydraulically operated
with guide wheels which shall be rested on support beams of the long travel car.
When the hot coke cake is ready in a particular oven to push the same to the hot
coke car, the long travel car shall be taken to that particular oven and hot coke tray
shall be fixed near the oven floor. The hydraulic cylinder shall operate and fix the hot
coke tray near the oven keeping the trolley level and oven floor level at the same
level. When the hot coke cake slides into the hot coke tray, the long travel car shall
travel and bring the cake to the quenching tower for quenching operation.
2.6.3.7 QUENCHED COKE PUSHERThis is a stationary machine located in the compacting station adjacent to the
quenching tower. The pusher ram shall empty out the quenched coke from the hot
coke car.
2.6.3.8 QUENCHING TOWERQuenching Tower shall have equipment to quench the hot coke cake with water and
push the same to coke hoppers for further processing.
When hot coke car comes to the quenching tower, the car shall be positioned so that
the hot coke cake is quenched by dousing large quantity of water. The quantity of
water required for this operation shall be of the order of about 70 T for each
quenching operation. But the loss of water through evaporation shall be in the range
38
of 0.70 T of water per ton of coke. In order to limit SPM emissions in the plume the
quenching tower shall be fitted with a system of grit arresters, which shall entrap
suspended particulate matter and make it fall back to the bottom of the tower.
A mild steel water tank of sufficient capacity forms a part of the quenching process
along with necessary pipes and spray nozzles which are fitted in the quenching
tower.
2.6.3.9 COKE SIZINGAfter quenching the hot coke shall be pushed from the hot coke tray to the coke
hoppers for further processing, particularly, for screening and coke cutting operations.
First it will be cut into required size of 30-80 mm and will be fed to vibrating screen
having 3 Decks. From first Deck, the oversize coke will go back to cutter. From 2nd
deck sized coke will directly go to Trucks for dispatch and from 3rd deck, the fines will
be taken away by a separate conveyor and stored at separate place. The
characteristics of coke oven gas and quality of metallurgical coke is given below.

2.6.3.10 SALIENT FEATURES OF COKE OVEN PLANT
Coke is required for captive consumption as a reducing & heat sourcing agent
in the blast furnaces to reduce Fe2O3/Fe3O4 ores to Fe.
Low ash metallurgical non recovery coke oven plant will reduce the
dependency on imported costly coke, generate coke using Indian & imported coal
and generate power based on waste heat recovery. It will also be cost effective,
environment friendly and energy efficient. This will help to meet the market
competition in steel sector.
“Non recovery” type coke making technology is practiced with provision for the
heat recovery from the waste gases. The technology is developed indigenously by
“The Central Fuel Research Institute, Dhanbad” and is comparable with the best
in the world.
Coke making is environmentally friendly. It is completely pollution free, as it
works on negative pressure in the ovens.
The power generated will be utilized to meet the captive requirement in the
coke oven as well as in the associated steel plant.

2.6.4 POWER GENERATION PROCESS (BASED ON COKE OVEN OFF–GAS)This Coke Oven Off–Gas flow rate is estimated to be 1,22,500 kg/hr from the Coke
oven plant of 1,20,000 T/a capacity having temperature around 950 0C is proposed to
be used in waste heat boiler for the production of high pressure steam. Super-
heated steam 45 T/hr, generated at a temperature of 485 ºC and a pressure of 65
kg/cm2 is used in Turbo Generator to generate 9 M.W. power. The power will be
utilized to meet the captive requirement in the coke oven as well as in the associated
steel plant. The exhaust gas from the plant is relatively clean and free from SPM and
hydrocarbons. The exhaust gas from boiler is vented through chimney of adequate
height. Flow chart for 9.0 MW power plant based on coke oven off gases is given in
Figure-2.9.

2.6.5 PRODUCER GAS PLANT
2.6.5.1 BACKGROUND OF PRODUCER GAS1. Producer gas is generated through thermal coal by heating and mixing water
with coal.Producer Gas has been in use in many industries as a cheap Gaseous
Fuel since Mid-nineteenth Century. The flow diagram of producer gas plant is given
in Figure-2.10. It was a development over use of solid‐fuel which had several dis

advantages, viz, lower thermal efficiency due to use of too much excess air,
difficulty in smooth control of furnace or kiln temperature, limited area of
application etc.
2. Right from the inception, Producer Gas was generated from the reaction of Air
+ Steam with coal‐bed in single‐stage generators either made of bricks in the initial
stages or steel with water jacket or refractory lining in the later versions. The grate
was also initially fixed but later on developed to Rotary Grate with better
throughput, easy movement of ash etc.
3. Before extensive production of Natural Gas and other Petro fuels at a
moderately lower cost, Producer Gas had been a versatile fuel owing to several
advantages over the solid fuels, viz, ease of production, better thermal efficiency in
the application, ease of control of furnace temperature, smoother flame etc. As a
result many industries all over the world have been using Producer Gas as a
cheaper energy in various field of applications viz, glass and ceramics,
Refractories, Lime‐klins, Dryers, Heating furnaces etc but with limited flame
temperature up to 1000°C to 1100°C.
4. But the producer Gas from earlier 19th
Century conventional Single stage
design has several disadvantages also. In these Gasifiers, the product gas comes
out from the top at a temperature of 470o to 500oC at which tar contained in the
gas cracks to soots and gummy maters, which deposit in the pipe lines, burner
nozzles etc, intern schocking them. This necessitates frequent ‘Burning Out’
operation store move the deposits which in turn results in interruptions and
reduced stream– days. The sketch of such a system has been shown in Figure1.
Here the consistency of operation and production can be achieved with the
installation of elaborate cleaning and detarring system at a high cost. At the same
time Calorific value of Gas also comes down owing to condensation of tar vapour
and other volatile matters to whatever extent it might be present in the gas. Due to
the above short comings, the various dis advantages which are normally faced in
single stage gasifiers are summarized below:
i. The Calorific value of Producer Gas is lower (1000 to 1250 kcal/Nm3)
ii. There is no consistency in Gas quality.
iii. There are frequent interruptions in the process due to de choking
operations.
iv. These producers can perform better only with high grade of coal with very
42
low ash content which is rarely found in the country.
v. Also clean gas from this Single stage Producers can be obtained only after
thorough cleaning in the elaborate cleaning facilities at a cost of Rs. 1.0 to 1.5
crore.
vi. As a result of Condensation and de tarring and unproductive generation of
soots, the gas make as well as calorific value of gas and thermal efficiency
becomes poorer (65% to 75%).
vii. Limited use in industries requiring lower flame temperature.
viii. These gasifiers are not pollution free which is a serious draw back under
the present day circumstances.

2.6.6 PULVERZED COAL INJECTION SYSTEMPulverized Coal injection (PCI) is a process that involves blowing large volumes of
fine Coal granules in to the BF. This provides a supplemental carbon source to speed
up the production of metallic iron, reducing the need for coke production. As a result
energy use and emissions can be reduced. However, as coke provides physical
support and gas permeability in the BF, its complete substitutions is not possible. The
amount of coal that can be injected will depend on the coal and coke quality, furnace
geometry, and operational practices. The flow diagram of pulverized coal injection
system is given in Figure-2.11.

2.11 WATER REQUIREMENT, SOURCE & UTILIZATION2.11.1 REQUIREMENT & SOURCES OF WATERThe source of water for the proposed plant will be Tungabhadra River. The
infrastructure facilities for supply of water from the source to the plant water reservoir
includes provision of intake structure and pumps at the reservoir and laying of piping
main from reservoir up to the plant. Water will be stored in an earthen reservoir of
capacity 0.6 million m3 approx. Raw water treatment plant will be installed for
pretreatment of raw water and the clarified water will be pumped through MS pipe
line to the proposed units.
The fresh water requirement for the proposed project will be about 3005 m3/d
including 2965 and 40 m3/d for domestic use. This will be met from Tungabhadra
river source. Water will be drawn only during rain and flood period from the
backwater of the river and stored in the water reservoir of 0.6 million m3 capacity.
The water from the reservoir will be used in the industry.
Government of Karnataka through its High Level Single Window Committee has
allotted 9012 m3/d (2 MGD) of water from Tungabhadra river. Further, the permission
from Irrigation Department for drawl 0.19TMC of water from the river is obtained.
2.11.2. UTILIZATION OF WATER AND WATER BALANCEIron and steel making and also the power plants are energy intensive where materials
undergo various cycles of heating and cooling. Water is predominantly used for
equipment and material cooling. In order to conserve freshwater, water economy
has been an underlying criterion for selection of plant and equipment. Open-circuit
industrial water re-circulation systems with evaporative cooling towers have been
planned for the secondary side of heat exchangers as well as for direct cooling
circuits. Process water losses will be compensated by adding make-up water of
respective qualities. In addition, it is used for steam rising in boilers, dust
suppression, domestic, fire Figurehting and greenery development. Fresh water is
needed in cooling systems to compensate evaporation losses and blow down. Water
balance for the industry is given in Table- 2.22.

3.1 INTRODUCTION
This chapter illustrates the description of the existing environmental status of the
study area with reference to the prominent environmental attributes. The existing
environmental setting is considered to establish the baseline conditions which are
described with respect to physical environment, air environment, noise environment,
traffic pattern and density, water environment, land environment, biological
environment, socio economic environment.
3.1.1 METHODOLOGY
The data was collected from both primary and secondary sources. The data thus
collected was compared with the standards prescribed for the respective
environmental parameters.
Secondary data was assessed by literature review of studies conducted in the
past by various private and government publications. The data thus collected were
compared with the standards prescribed for the respective environmental
parameters. Topography of the study area is given in Figure-3.1.
Primary data sources include the data collected through environmental
monitoring/ survey of the study area during the study period. The studies involved
conducting field studies and analyzing various parameters that might be affected due
to the industry and conducting socio-economic survey among the people. For
reconnaissance survey the sampling locations were identified based on:
Existing topography and meteorological conditions
Locations of water intake and waste disposal points.
Location of human habilitation and other sensitive areas present in the
vicinity of the proposed project site.
Representative areas for baseline conditions.
Accessibility for sampling
The scoping and the extent of data generation were formulated based on
interdisciplinary team discussions, and professional judgment keeping in view of TOR
assigned by MOEF. The base line studies started with reconnaissance survey and
58

Air quality at the project site: Ambient air quality analysis was conducted at the project site by-weekly for 3 months from11.12.2013 to 11.03.2014. The analysis reports are appended in the Table-3.7 below
Note: 8 hourly or hourly monitored values, as applicable, shall be complied with 98%
of the time in a year. 2% of the time, they may exceed the limits but not on two
consecutive days of monitoring.
Whenever and wherever monitoring results on two constitutive days of
monitoring exceed the limits specified above for the respective category, it shall
be considered adequate reason to institute regular or continuous monitoring and
further investigation.
3.3 3.4 Observations
It has been observed that the maximum concentration of all the parameters
monitored at all the locations are within the limits specified by MoEF (as per the
notification dated 16th November 2009 for industrial, residential & rural areas).
Marginally high values at Vasthu Building are due to the frequent movement of
vehicles.

3.4 NOISE ENVIRONMENT
The proposed project is an integrated steel industry and hence requires movement of
raw materials, products, fuels, tools & tackles required for its manufacturing process
and also transportation of finished products to its destination. The movement of
personnel from their residence to industry would also result in a moderate increase in
the traffic, which would not result in any drastic change in either the existing traffic
pattern or noise levels of the area as accommodation facilities are proposed within
the project site for most of the employees.
Background noise levels were measured using integrated sound level meter in 9
locations (Table-3.9). Monitoring locations were located within the study area (Figure
3.4). A sound level meter was used for measuring the noise level at one-hour interval
continuously for 24 hrs at 1.5 m above ground level, about 3 m from walls, buildings
or other sound reflecting sources.
The measurements were carried out in such a way that the monitoring locations were
1 m away from the sources and 1 m away from the edge of the roads. The maximum
and minimum noise levels are presented in Table 3.9 and the limits as per
Environmental Protection Rules, 1986 for industrial, commercial & residential areas
are presented in Table-3.10 as under.

Resistance shows the sub-surface formation and its nature. Percolation (seepage)
depends on the formation having more porosity. Porosity of a rock or soil is a
measure of the contained interstices. It is expressed as the percentage of void
space to the total volume of the mass,
α = Porosity then,
α = 100W/ V
W- volume of water required to fill
V- total volume of the rock
Porosity range from zero to more than 50 percent. It directly depends upon the grain
size shape and arrangement of individual particles, distribution by size and degree of
cementation and compaction. In consolidated formations, removed of mineral matter
by solution and degree of fracture are also important.
Vertical distribution of ground water is primarily important in study of pollution and its
pathway. The substance occurrence of ground water may be divided into zones of
saturation and aeration .In the zone of saturation all interstices are filled with water
under hydrostatic pressure .In the zone of aeration all the interstices occupied
partially by water and partially by air.
Water in the soil water zone exists at less than saturation except temporarily when
excessive water reaches the ground surface as from rainfall or irrigation. The zone
95
extends from the ground surface down through the major root zone .Gravitational
water is excess soil water which drain through the soil under the surface of gravity.
Topography, soil structure, rock formation and vegetation plays an important role for
the passage of the pollutants to the sub surface. In the study area, run-off is more
than infiltration and soil structure is of finite in size and compact because of the
industrial activities. Further, soil is cemented by a fine clay & hence it will not permit
to the sub surface. Area is devoid of any thick vegetation which can allow to
percolate pollutants to the sub surface by means of root system. Hence topography,
soil and vegetation in the plant area will not permit any pollutants to the sub-surface.
3.9.1.7 DRAINAGE AND WATER BODIES
The drainage system noticed in the region is almost dendritic and small portion of
the region is in parallel form and the drainage density is low to moderate forms the
network of several streams originating from the mounds & hillocks. The
Tungabhadra River, which is a prominent water body, flows at northern part of the
study area from northwest to eastern part of the region.
The rest of the water bodies/ tanks in the region were formed by the construction
of bunds across the minor streams (above 3rd & 4th order) for storage of water for
irrigation. The Dhanayakana Kere is the largest among the water bodies and is
located at southeastern part of the site. Several smaller lakes exist throughout the
area and cater to command areas for irrigation during monsoon season. However,
most of the water bodies in the vicinity go dry during summer due to zero inflow
from the drainage system.
3.9.1.8 GROUND WATER POTENTIAL
Ground Water potential has been assessed by site investigation & as per the data
collected from the Central Ground Water Board/ Department. The entire region is
mainly underlined by granitic gneisses and Dharwar schists that are known to be
hard rocks, which have least porosity and permeability. Ground water is found in
pockets in the area in the zones of weathered, jointed and fractured rocks.
96
Bore wells in the area are of 152 to 165mm dia. and are normally have a depth of
70 m to 120 m. The maximum yield of the bore well in the region recorded is
15m3/hr., and the pumping period varies from 6 to 8 hours/day. The bore well data
from State Panchayat Raj Engineering Department (PRED) indicates that about
80% of the bore wells yield between 0.6 to 5m3/hr and maximum depth of high
yielding bore wells is between 75 to 90m below ground level. Most of the bore wells
deeper than 50m, tap the water from fractured zones encountering between 35m to
90m depth and forms medium to deep aquifers.
3.10 ECOLOGY3.10.1 FLORA AND FAUNA
It is necessary to know the conFigureuration of vegetation, plantation, animals,
birds, aquatic life, wildlife features, bird sanctuaries, national parks, reserved
forests etc., in the study area in order to assess the probable effect likely to be
reflected on the existence of these features after the commissioning of the
proposed project. Presently the proposed site is a plain land with less vegetation
cover mainly herbs.
In the Ramagad Reserve forest which is dry deciduous in nature. It consists of
bare residual hill containing hard rock formation enriched with iron ore as such
the conditions are not much favorable for tree growth as very little soil exist on the
hill. The flora does not contain much timber yielding species nor do they have
good green cover. List of flora found in the Ramgad Reserved Forest,
Mariyammanahalli tanda Village, Mariyammanahalli, Nandibanda, Dhanapura
Village and TB Dam area are tabulated below.

CHAPTER – 4ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES
4.1 INTRODUCTIONEnvironmental impact in the study area is any alteration of environmental conditions
or creation of new set of environmental conditions, adverse or beneficial, caused or
induced by the impact of project. Prediction involving identification and assessment
of potential impacts of the project on surrounding environment is a significant
component of REIA studies. The likely Impacts of various activities of the proposed
project on the environment were identified. These impacts were assessed for their
significance based on the background environmental quality in the area and the
magnitude of the impact. All components of the environment were considered and
wherever possible impacts were evaluated in quantitative/qualitative terms. Several
scientific methods are available to qualify and predict the impact of project on
environmental factors such as water, air, noise, land ecological socio economic.
Such predictions are superimposed, over base line environmental status to derive
post project scenario of the environmental conditions. The resultant (post-project)
quality of environmental parameters is reviewed with respect to the permissible limits.
Based on the impacts thus predicted preventive and mitigation measures were
formulated and incorporated in the environmental management plan to minimize
adverse impacts on environmental quality during and after project execution.
The environmental impacts can be categorized as primary and secondary. Primary
are those which are directly attributed to the project and secondary impacts are those
which are indirectly induced due to primary impacts and include those associated
with investment & socio-economic status. The project impact may be broadly divided
into two phases.
During construction phase: These may be regarded as temporary or
short term and ceases with implementation of the project.
During operation phase: These impacts are continuous warranting built

The project proponents have permission to draw 0.19 TMC of water only when the
water level in the dam is reached highest level i.e when the dam is full.
4.4.2.2 DISCHARGE RATE
Agreement made between Executive Engineer Munirabad and SLR metaliks Ltd to
draw 0.19TMC in 30 to 40 days when the dam level is full.
4.4.2.3 DISTANCE FROM THE PROJECT
The approximate distance of tapping point from the project is 2km.
4.4.2.4 SURFACE HYDROLOGY AND WATER REGIME
Tungabhadra River is one of the major tributaries of Krishna. Tungabhadra desires its
name from the confluence of two streams, the Tunga and the Bhadra both of which
rise in the wooded eastern slopes of the Western Ghats in the state of Karnataka and
flow eastward. The river runs 382 kms in Karnataka. Catchment area of the
Tungabhadra reservoir is 28177 sqkm .The river basin is influenced by the southwest
monsoon with copious inflow during monsoon which dwindles to few cumecs in
summer months .Tungabhadra reservoir impounds 3766 mm3(133TMC) of water in
the reservoir.
169
4.4.2.5 WATER USAGE
0.19TMC w a t e r from Tungabhadra reservoir will be taken. The water will be
stored in a reservoir tank and pumped to the plant for treatment and utilization as
make up cooling water and other applications. In the unlikely event of a power failure
an overhead tank of sufficient height & Capacity has been provided to ensure
nonstop supply as continuous water flow is as must to cool the system. The water
softener is provided to avoid scaling in the pipelines, which will reduce the
efficiency of the whole system.
The quantitative and qualitative information on water utilization and waste water
generation in the proposed industry is presented in Chapters – 2,9. The information
also includes the built in facilities and measures for treatment and disposal waste
water. The impacts expected from withdrawal water from river and disposal of waste
water on land is discussed in this section.
4.4.2.6 IMPACT OF WATER WITHDRAWAL FROM RIVERFresh water requirement to the proposed project will be 3005 m3/d. This will be met
from the back water source of Tungabhadra river and dam. The Tungabhadra river is
a perennial river and joins to the dam. The water from river and dam are mainly used
for agriculture uses and also to meet domestic needs of downstream towns and
villages. Drawl of water from river, especially during summer and lean flow period is
likely to affect the competitive users river water. However, the industry will draw water
only from the back water source of the river mainly during flood period. The
government has allowed drawing water up to reservoir level + 1633 feet if when the
reservoir level goes below 1633 feet the firm will not be permitted to draw water. The
drainage area of the Tungabhadra river in the western ghats receives about 4500mm
of rainfall while the project area and rivers running in the peninsula receives about
480-760mm rain fall.

During the lean season also there will be minimum flow of water in the upstream as
well in the downstream. There will be discharge of water by upstream projects like
tunga, varadha and hirehall projects which will ensure the availability of water for
drinking water and other projects.
The water, thus drawn will be stored in a huge reservoir of 6 lakh m3 capacity for
subsequent use in the industry. Storm water gutter net work and water harvesting is
practiced in the industry and water realized during rainy period from them is stored in
the above reservoir to augment the water source.
4.4.2.7. WATER CONSERVATION PLAN
The following steps are comprehensively foreseen for optimizing the water
consumption in the expansion project,
1. Effectively monitoring and control of water consumption on day to day
basis .
2. Water meters will be installed at all consumption and make up water
points to monitor and control the water consumption.
3. All sumps and transfer canals in the plant will be provided with the
adequate RCC and PCC bases to avoid water seepage losses.
4. The drip irrigation system and spray fountain systems shall be adopted
wherever applicable to reduce water consumption for horticulture and
gardening.
5. STP treated water will be re-used for maintenance of garden and green
belt development.
6. Rain water harvesting will be employed for storm water to collect and
conserve the water for future usage.
171
7. Roads will be asphalted and yards shall be concreted to avoid water
sprinkling needs to keep the emission levels of ambient air low.
8. Necessary caution and educative boards , slogans related with water
conservation will be displayed at vantage points to create awareness among
entire workforce.
9. Plant water balance will be reviewed periodically by top management to
effectuate all steps for continuous improvements on water conservation front.
4.4.2.8 TREATMENT & UTILIZATION OF EFFLUENT4.4.2.8.1 WASTE WATER MANAGEMENTThe source and quantity & utilization of domestic and trade effluents generated in the
industry are given in Table-4.12.
4.4.2.8.2 DOMESTIC EFFLUENTThe domestic effluents are generated from rest rooms and canteen. They are treated
in septic at the source location and over flow from septic tank is treated sewage
treatment plant. Total employees in the industry for the present activities are 450 and
additional employees for proposed activities will be 500. Domestic effluent generated
from existing and proposed units will be 22.5 m3/d and 32 m3/d respectively. The
sewage treatment plant consisting of bar screen, oil grease separator, neutralizer,
equalizer, aeration tan and secondary clarifier is designed for 60 m3/d capacity. The
characteristics of untreated and treated effluent are given in Table-4..15Treated
effluent is collected in a sump and then sent for use on land for greenery and green
belt development. The flow chart of STP is given in Figure-4.11.
Table-4.14 Characteristics of Untreated and Treated Effluents
4.4.2.8.3 INDUSTRIAL EFFLUENTThe industrial effluents, 473 m3/d generated in the industry are manly blow down
from circulating cooling water and circulating scrubber and quenching water. They
contain mainly the suspended and dissolved inorganic matter, The presence of BOD,
COD or organic matter is insignificant. The purge and blow down waters are
neutralized and settled in the guard pond of about 100 d capacity. The over flow from
guard pond will be utilized on land for greenery development. It will also be used for
spraying on roads and land for dust suppression. This will be also be used in the
plant for makeup of cooling water loss. The guard pond is of earthen impervious
construction & located at ground level. The tank interior is suitably compacted and
finished.
Wastewater from slab caster and rolling mill complex are likely to contain suspended
solids and oil & grease. These effluents will be routed to settling pits fitted with oil &
grease trap. The clarified water is reused in the process.

4.4.2.9.1. UNDERGROUND TANKS Total yield from roof areas was calculated based on 90% dependability
rainfall (760 mm) & 0.90 runoff coefficients.
Roof top rain water down take pipe is further connected to sand bed
filter for filtration.
Filter needs to be cleaned periodically during the rainy season to
remove the filtered material and to keep the filtration system clean.
The filter water is proposed to be stored in existing cluster wise
underground water tanks.
This would provide additional benefit of flood management via storm
water detention for RWH.
Rooftop downspouts from the respective unit will be designed to drain
to main storm drain system with a flow splitter arrangement for drainage to the
proposed underground storage tank.
During the storm events of the wet season, valve located at the flow
splitter will be operated to direct water to the tank.
This stored water is recommended to be used for gardening and
housekeeping purposes.
4.4.2.9.2. RECHARGE PITS AND HOLDING PONDS
Recharge pits of size 3.0x3.0x3.0 m with bore well and 2 existing
holding ponds have been proposed for recharging at various locations to
enable ground water recharge.
Rain water from storm drain will enter the recharge pit through filter
media and then to bore wells through slotted casing pipes.
Feasibility of recharge through bore wells is based on geotechnical
report.
Four holding tanks are proposed to harvest the runoff from the
landscaped area.
13 recharge pits around existing bore well are proposed.
175
4.4.2.10. AQUIFER MANAGEMENT PLANThe rock formations occurring in the area fall under category of hard rocks. They
are the oldest rock belongs to ARCHEAN age. They lacks primary inter granular
porosity. They are characterized by secondary porosity through weathering and
fracturing. The thickness of the soil and depth of weathering vary from place to
place.
As per the topographical survey of the area , terrain in North , south west and
south are relatively at higher elevation of granitic and schistose formations
showing a first stage of formation of water Table where run-off is more than
infiltration , an impervious and poor aquifer because of scanty rain fall (760
mm)and higher temperature (38-46°c ).ground water in zone of vegetation, which
is partially filled up with water and air will be dried up during summer season . so
ground water Table fluctuation is more during the summer period . thus the above
area comes under poor aquifers. Only small portion of the area towards north
&north east showing feasibility of aquifer nature. A seasonal nalla which is running
from west to north and north east showing presence of aquifer.
4.4.2.10.1 MANAGEMENT PLAN FOR RECHARGING THE AQUIFERDue to rapid urbanization (industrial) activities, infiltration of rain water into the sub
soil has decreased resulting in lesser recharging of grounded water. The scenario
requires an alternative source to bridge the gap. Rain water which is available and
is purest form of water would be an immediate source of water supply by catching
water wherever it falls.
Rain water harvesting (RWH) is the process of collection and storing of water in a
scientific and controlled use. It includes,
RWH in paved and unpaved areas (open fields,parks,pavement,land
scapes etc)
RWH in large areas with open ponds, lakes, etc.
Capturing rain water in situ.
Replenishing ground water through recharging of rain water by using
soil column.
Check dam across the seasonal nalla.
STEP wells
Lake culture i.e. chain of water storage structures recharged to ground
through recharge pits, dug wells, soak pits etc.
176
4.4.2.11. LEACHEATE STUDY FOR THE STOCK PILES
The raw materials and finished product are insoluble in nature. There will be no
charge in Chemical composition of the water .These will not be any waste disposal
site in the project area. The possibility of pollution due to seepage or percolation to
the sub surface will be controlled by constructing shed to the stock piles where ever
possible and the flooring will be made impervious by concreting with water proof
plastering.
4.4.2.12. FLOOD HAZARD
River Tungabhadra a tributary to the major River Krishna is with in 10km radius from
the SLR Metaliks project site. Tungabhadra River derives its name from the
confluence of two stream the Tunga and the Bhadra both of which rise in the wooded
eastern slopes of the western ghats in the state of Karnataka and flow eastward.
After confluence of these two streams at Kudali near Shimoga, the Tungabhadra runs
for about 531kms and joins the River Krishna at Sangameshwaram near Kurnool in
the state of Andhra Pradesh .The catchment area of Tungabhadra reservoir is 28,177
km2. The river basin is influenced by the southwest monsoon with copious inflows
during monsoon which dwindles to few cumecs in summer months.The drainage area
of the Tungabhadra river in the western ghats receives about 4500mm of rainfall
while the project area and rivers running in the peninsula receives about 480-760mm
rain fall.

The Tungabhadra reservoir has not been provided with flood storage capacity for
flood absorption .The full reservoir level and maximum water level of the reservoir are
same and is at 1633 ft. Therefore the entire flood impinging the reservoir has to be
either stored to the extent possible or passed over the spillway. The spillway with 33
gates is designed to allow a maximum discharge of 6,50,000 cuses at full reservoir
level. The operation of spillway gates is carried out in accordance with approved
schedules duly ensuring the safely of the dam and is maintained by CENTRAL
WATER COMMISSION.
The proposed project viz SMS plant, rolling mill, coke oven plant, coke oven power
plant, producer gas plant, PCI plant, oxygen plant are part of integrated steel
industry. In the integrated steel industry air pollution is a major concern than the
water pollution. The proposed projects will be designed by keeping the zero
discharge policy or no discharge policy.
Topography of the proposed Project site is at higher level with respect to Temporary
Bench Mark (TBM) compared to the TBM of the river so there will be no flood effect
during the river flooding. The industry is located at a distance of 600 to 700m from the
high flood level (HFL) of the dam. The lowest level in the project site is 504(1653 ft) m
above MSL and HFL level or full supply level is 497m, However the dam gates will
be opened even before reaching 497 (1633 ft) m above MSL. The satellite imagery
showing the water levels of different season is given below which clearly shows that
the water does not enter into the project site.

The existing plant consists of 262m3 blast furnace, 33m2 sinter plant and 6MW blast
furnace off gas based power plant. Now it is proposed to install value addition units
to the existing product viz 0.30 MTPA steel plant, 0.32 MTPA rolling mill, 0.12
MTPA coke oven plant, 9 MW coke oven off gas based power plant, 120 TPD
producer gas plant. As the proposed units require prior Environmental Clearance
(EC ) from MoEF as per EIA notification Act 2006, we have submitted the form-1 ,
178
prefeasibility report and proposed TOR’s to MoEF. The Proposal was considered
by reconstituted Expert Appraisal Committee (Industry) in its 13th meeting held
during 18th to 20th November,2013 and TOR for EIA studies was deliberated &
accordingly EIA studies were conducted.
The proposed project viz SMS plant, rolling mill, coke oven plant, coke oven power
plant, producer gas plant, PCI plant, oxygen plant are part of integrated steel
industry. In the integrated steel industry air pollution is a major concern than the
water pollution. The proposed projects will be designed by keeping the zero
discharge policy or no discharge policy. The wastewater streams will be in
closed circuit.
Proposed project sites are located at a distance of 600-700m from the HFL of the
Tungabhadra Dam, considering the distance of water body from the proposed
expansion site, SLR Metaliks has proposed management plan to eliminate the
water pollution on Tungabhadra river.
No manufacturing units will be located near water body, north side will be covered
dense vegetation lalyer.
4.4.2.13.1 STORM WATER MANAGEMENTTopography of the proposed Project site is at higher level with respect to HFL/FSL of
the river .The lowest level in the project site is 504(1653 ft) m above MSL and HFL
level or full supply level is 497m, the storm water generated in the proposed site will
be collected through efficient drainage system and stored in 3 number guard ponds
for reuse.
Strom water gutters will be constructed in the premise as per the standards taking
into peak runoff factor and flash flood rate. The storm water drains will lead to rain
water reservoirs/ guard ponds constructed at the lowest level of the premise as
shown in the layout plan. The annual rainfall in the region is about 759 mm and is
spread from June to November. The maximum monthly rainfall is about 287 mm. The
unit posses a total of 190 acres land. The area consists of 76 acre built up plant area,
57 acres open area and 57 acres green belt area. The guard ponds will be designed
by considering the worst case scenario peak monthly rainfall for 12 months and there
is no consumption of collected storm water in process or for other activity. However in
reality The stormwater/ runoff collected in reservoir will be used for process, dust
179
suppression & greenery development in the factory. The storm water collected from
other premises is given below.

coal/coke stock yard will be led to settling tanks/catch pits to remove suspended
particles. The coal/coke particles are recycled to the plant. The rain water after
settling is collected in to rain water storage pond for use in the plant, dust
suppression and greenery development.
4.4.2.13.3. WATER CONSERVATION1. Adaptation of less water consuming technologies/ dry processes like air
cooled condenser (ACC) in place of water cooled condenser in proposed
captive power plant, thereby reducing the wastewater generation.
2. Effectively monitoring and control of water consumption on day to day
basis .
3. Water meters will be installed at all consumption and make up water
points to monitor and control the water consumption.
4. All sumps and transfer canals in the plant will be provided with the
adequate RCC and PCC bases to avoid water seepage losses.
5. The drip irrigation system and spray fountain systems shall be adopted
wherever applicable to reduce water consumption for horticulture and
gardening.
6. STP treated water will be re-used for maintenance of garden and green
belt development.
7. Rain water harvesting will be employed for storm water to collect and
conserve the water for future usage.
8. Roads will be asphalted and yards shall be concreted to avoid water
sprinkling needs to keep the emission levels of ambient air low.
9. Necessary caution and educative boards , slogans related with water
conservation will be displayed at vantage points to create awareness among
entire workforce.
10. Plant water balance will be reviewed periodically by top management to
effectuate all steps for continuous improvements on water conservation front.
4.4.2.13.4. GARLAND DRAINSGarland drains will be constructed in the proposed industry to make sure that all the
storm water generated will be collected and diverted to guard pond. Hence there is
water is permitted to go out of the plant premises.
182
4.4.2.13.5. AIR POLLUTION CONTROL MEASURES
The industry will adopt effective air pollution measures to minimize the dust
generation, by installing APC like ESP, Cyclone, scrubber, bag filters, dedusting
systems, water sprinklers and developing greenbelt around the premises.
Water conservation plans, rainwater harvesting measures and storm water
management system will effectively reduces the impact on Tungabhadra dam due to
proposed integrated steel project.
4.5 NOISE ENVIRONMENT
4.5.1. SOURCE OF NOISE
During the operation phase of the project, major sources of noise pollution are
expected to be from various machines used for production and vehicular traffic. The
principle source of noise from industry are from fans, centrifuge, turbine, steam traps,
steam vents etc., the observed noise level of these machineries in existing Iron
making factories is given below.
i. Steam turbine - 90 – 95 dB(A)ii. Diesel Generator - 80- 85 dB(A)iii. Fans, compressors and blowers - 85-90 dB (A)iv Crusher - 80-90 dB (A)
vi. Vibratory screen & conveyors - 85-90 dB(A)Most of these generate higher noise. The movement of vehicles like trucks & tractors
has noise level of 70-80 dB (A). The machinery and techniques used for
manufacturing proceed would be such that there is minimal nuisance of noise in the
surrounding region. However as a precautionary measure, enclosures will be
provided where ever possible for all the major mechanical units to arrest the sound
waves travelling outside the plant area.
4.5.2. IMPACTS & MITIGATION MEASURESThe assessment of the impacts due to noise pollution on the surrounding community
depends upon characteristics of noise source (instantaneous, intermittent, or
continuous in nature), period and duration and the location of noise source with
respect to noise sensitive receptor.
Efforts shall be done to bring down the noise level due to the D. G. set, with in the
allowable limits of about 70 dB(A) by sitting and control measures. The D.G. set is
183
provided with acoustic treatment for minimum 25 dB (A) insertion loss exhaust muffler
of suiTable quality is provided to offer an insertion loss of about 25 dB(A). Steam
turbine is located in the separate building and acoustic treated premise. Workers at
these equipments are provided with noise control appliances. The noise impact of the
industrial activity is insignificant at the boundary level of the industry. The noise level
due to project activity is limited to the project site only and little impact on surrounding
area. However, movement of vehicles will increase noise levels on the roads and
their near vicinity. SuiTable measures have to be adopted for occupational noise
safety in factory and good maintenance of vehicles. The expected noise level from
proposed project activities at project boundary would be less than the statutory
requirement, ie. Less than 75 db (A) during day time and 70 db (A) during night time.
4.5.3. NOISE QUALITY STANDARDS
The permissible occupational noise level and exposer time is given below.
Standards for Occupational Noise Exposure

Note:- No exposure in excess of 115 of dB(A) is to be permitted. For any period of
exposure falling in between any Figure and the next higher or lower Figure or
indicated in column (1). The permissible level is to be determined by extrapolation on
a proportionate scale. Similarly, the standards for ambient noise level are given
below.

To meet these limits, noise abaterment measures as indicated in EMP will be
incorporated with the project.
4.6 SOLID WASTE MANAGEMENT4.6.1 IMPACT OF METALLURGICAL WASTE AND FINESIn an integrated steel plant , the sources of fine dust generation are as under:
i. Raw materials handling plant.ii. EOF plant
Metallurgical waste and fines are carried with the fugitive gases, scrubber water and
quenching water.
Metallurgical waste and fines are generated at furnace, crushers, charging and
unloading, quenching of hot material etc. These are collected at dust arresters and
settling tank of circulating quench and scrubber water. The fumes and exhaust gases
carrying dust are generated at furnace and quenching operations. The
characteristics of metallurgical waste generated in the proposed project is given
below
Characteristics of Solid Waste
Sl.No
Source Composition of Metallurgical waste and finesFe CaO Mg
The detailed solid waste generated and its disposal handling is given insection 2.12.3.
185
4.6.2 HANDLING AND UTILIZATION OF COAL ASH
Coal ash is produced in producer gas plant (PGP) where in 220 T/d of B- grade
Indian coal is used as an input. The coal contains about 33% ash. Hence, ash
produced from PGP will be 53 T/d. The ash discharged from the unit will be collected
in a shallow pit of size 20m x 30m x 1.0m depth, 4 nos. The ash is sprayed with water
to quench the hot ash and also to prevent dust evolution.
The moistened and cooled ash is then used for brick making. Each pit has a capacity
to hold about 10 d production of ash from the PGP and lined with geo-membrane to
prevent the seepage.
The pit is produced with the arrangement to collect the leachate if any. The leachate
thus collected will be reused for quenching of hot ash. The capacity of leachate pit is
20 m3/d (Size 3m x 3m x 3m). The location of ash pit is shown in lay out plan.
4.7 SOIL QUALITY
The soil characteristics in the study area are given in Chapter-3. It is seen that the
soil quality is of low fertility. Waste water and solid waste if discharged with out
control on land are likely to affect soil quality. Factory effluent, mainly the purge from
circulating cooling water is treated to standards and then utilized on land.
4.8 BIOLOGICAL ENVIRONMENT
The study area is mainly barren vacant land. There are no forests and ecosensitive
sites in the vicinity of the site except the river Tungabhadra which is at 5 km north
from the site. The backwater of TB reservoir is about 600-700m which goes on
increases upto 3km. No human habilitate within 1.5 km from the site. There are no
endangered flora and fauna species in the region. Vehicular movement during night
will be restricted to avoid adverse consequence to birds and wide animals in the
region. The project activities are restricted to the factory site except the
transportation of raw material and products. There is no discharge of solid or liquid
wastes to the environment. Green belt and greenery will be developed in the premise
covering more than 33% of area. The plantation will comprise of fruiting trees, soil
improving and air pollution abatement tress. No eco sensitive receivers or rare /
endangered species of fauna were observed in the study area.. Thus, the impacts on
flora and fauna will be insignificant.
186
4.9 SOCIO-ECONOMIC IMPACT
This section discusses the project activities and the extent of the potential impacts
anticipated on socio-economic status in the region. Based on the nature and type of
impacts, the assessment has been divided into 3 category i.e. positive, negative and
negligible impacts. For example, the positive impacts include job opportunities for
men and women, better utilization of land, preservation of environment, infrastructural
development, etc. Long term impacts are also taken into account i.e. relocation,
democracy, aesthetics, accessing utilities, impact on archeological sites, etc.
Negative impacts include adverse impacts on health, air pollution including noise,
road safety, odors etc.
4.9.1. POSITIVE IMPACTSJob opportunity: during the social impact assessment process, locals raised the
question regarding more job opportunities. The benefit relate to direct employment
associated with the construction of the facility. Jobs would be given to unskilled, semi
skilled as well as skilled labor category, for which locals would be given preference
and thereby the overall development of the region is envisaged.
Wider economic growth: this project will increase the economic activities around the
area, creating avenues for direct/indirect employment in the post project period.
There would be a wider economic impact in terms of generating opportunities for
other business like workshops, repair and maintenance tasks etc.
Infrastructural development: this project would enhance the infrastructure in the
vicinity, which also involves road upgrading.
Aesthetics environment: the architectural character of the new building, the vistas and
landscaped areas created would improve the aesthetics of the area.
Additional revenues: the development of land for any purpose creates both an
immediate demand for services and a flow of revenues to the community from a
variety of sources, for example property tax, licenses and permits fee etc.
4.9.2. NEGATIVE IMPACTSAdditional traffic in the area is a matter of concern to the local people. This effect
would be prominent during construction as well as operation phase. The probability of
inconvenience faced due to frequency of truck movement during construction phase
and operation phase would be minimized by better control of traffic movement in the
area. Noise levels expected from the planned operating conditions have been
187
assesses and are likely to be within accepTable levels. The impacts have been
mitigated by the suggested measure in the “air control and management section”.
Transient labor population from the surrounding areas might come and work at the
site. Though majority of population would be recruited locally, limited labor with
specific skills will be recruited from outside the region. Therefore, no significant
pressure on local infrastructure is envisaged. All environment health &safety (EHS)
practices will be followed according to labor commissions notification.
4.9.3. NEGLIGIBLE IMPACTSAs there is no existing settlement on the proposed project area, there are no issues
of resettlement or rehabilitation.
4.9.4. CONCLUSIONOverall, the project will have major positive impacts on the region in sense of
environment as well as social. Negative effects are not expected if there is dedicated
environmental planning and if at the same time the interests of population and the
areas directly adjacent to the project site are considered.
Establishment of project will enhance the transportation activity. This will create
opportunities to the localites to start vehicle garages. With development of the
industry the roads and communication facilities will be enhanced. The expansion of
integrated steel unit will also create job opportunities to the local mass.
Presently the educational facilities in the study area are limited to primary and high
school. With establishment of this industry the transportation, public mobility and job
opportunity along with associated activities in the region may increase. These
activities will improve economic condition of the local population. The presence of
the industry will enhance commercial activities, which inturn will improve the
economic conditions of the population. Service infrastructure like transportation,
health care, education, communication facilities may improve considerably. The
availability of power from the industry will help to reduce the power scarcity and
frequent power failures in the region by stabilization of the power in the grid, which
will improve power supply to irrigation pump sets and house hold requirements.
188
4.10 GREEN-BELT DEVELOPMENTGreen belt and greenery will be developed in about 65 acres of land. The species
developed will be as per CPCB guide lines. Assistance and guidelines will also be
availed in development of greenery in the industry.
All the premise green belt of about 20 m will be developed. Line trees will be
developed on either side of the internal roads as well on all approach roads to the
industry,
Lawns will be developed around plant and administrative buildings. Green belt of 10
to 20 m will be developed around open bulk storage yards.
A green belt helps to reduce the pollutant level in the ambient air by preventing the
fugitive dust being carried away by wind. They not only act as a pollution sink for
variety of air pollutants but also replenish the air with much needed oxygen. These
can help to reduce the pollutant level in the air environment. The degree of pollution
attenuation by a green belt depends on its height and width, foliage surface area,
density, dry deposition, velocity of pollutants and the average wind speed through the
green belt. The main objective of green belt around the factory is:
1. Mitigation of impacts due to fugitive emissions
2. Attenuation of noise levels
3. Ecological restoration
4. Improvement in aesthetic environment quality
5. Waste water reuse and re-cycling..
6. Soil erosion prevention
The proposed plant will be located adjacent to the existing steel unit. A very
elaborate green belt is already developed by industry at the existing steel unit.
Greenery and green belt will be developed in the proposed project promise as per
CPCB guidelines. Necessary help and guidelines will be availed from the
departments of Karnataka State nurseries and forest to get suiTable species of
plants. Keeping in view of the soil and water quality available in and around the
project site and the topography of land, following species are considered for green
belt development.

4.12 TRAFFIC DENSITY AND ITS IMPACT ON ENVIRONMENTAfter expansion of the project the transportation of material to and from industry will
be enhanced. Expansion is basically a production of down stream or associated
products with out the use of additional ore or other raw materials. Earlier coke was
imported and used in the blast furnace. In the proposed plant coke is manufactured
193
from coking coal. Hence, Coal will be procured to the industry instead of Coke.
Additional low grade coal is also procured for use in producer gas plant and other
furnaces. Liquid fuels needed in heating furnace are procured from refineries located
in Mangalore. In the present plant pig iron is manufactured and sent to the
consumers through lorry transport. After expansion, instead of pig iron rolled and
casted steel products will be sent to the consumers through lorry transport. Hence,
the quantity of product transported from the industry will be nearly same even after
expansion of the project.
The materials from and to the site are transported mainly through lorry vehicles.
These vehicals move mainly through Hospet-Harihar State high way and
Chitradurga-Solapur national high way (NH-13). These high ways consists of 4/6
lines and well developed. The traffic density on this road is much less than its
allowable limits. The existing traffic and additional traffic due to expansion are given
below.
4.12.1 TRAFFIC SURVEYTraffic survey is the study of flow of traffic/vehicles, designing and operating traffic
system to achieve safe and efficient movement of vehicles, persons and goods.
Traffic studies are carried out to analyse the traffic characteristics. These surveys are
conducted to assess the impact of traffic with reference to road safety and carrying
capacity of roads. This will help to in deciding the geometric design feature and
traffic control for safe and efficient traffic movements. The density of vehicles on the
road is given in Table-4.14.
Passenger Car Unit ( PCU)PCU different classes of vehicles such as cars, vans, buses, trucks, auto rickshaws,
motor cycles, pedal cycles, bullock carts, etc are found to use the common road way
facilities without segregation on most of the roads in developing countries like India.
The flow of traffic with unrestricted mixing of different vehicle classes on the road
ways forms the heterogeneous traffic flow or the mixed traffic flow. It is a common
practice to consider the passenger car as the standard vehicle unit to convert the
other vehicle classes and this unit is called as Passenger Car Unit or PCU. Thus in
mixed traffic flow, the traffic volume and capacity are generally expressed as PCU
per hour or PCU/lane/hour and the traffic density as PCU per km length of lane.
Recommended PCU units for the practiced purposes are given below.

i.Least stress on resources including raw materials and utilities
ii.Reduce, Recycle and Reuse of wastes
iii.Least or no pollution from the industry
iv.Least or no risk to human and property
v.Least or no adverse impacts on environment
The technology options for the proposed plant were considered based on efficient
utilization of raw materials, fuel, power and water.
5.4 NO PROJECT OPTION
No project option is considered mainly with respect to:
i. Utilization of natural resources
ii. Environmental impacts, harmful or beneficial
iii. Benefits of the industry to the society
The project is proposed mainly for the purpose of best utilization of existing
infrastructural facilities including land, water, manpower, roads etc. The expansion
project does not involve any additional ore. The project is mainly for value added
products such as steel and rolled products utilizing already available B.F iron. Coke
will be produced to meet the its requirement in the existing Blast furnace plant.
Oxygen and nitrogen requirement to the steel plant will be met from the proposed air
separation unit. Power plant is based on waste heat available in coke oven off-gas.
The proposed project will not cause depletion of natural resources or the significant
adverse impacts on environment. On the contrary, it will produce value added
products of national importance resources such as steel with low resource utilization.
Hence, “No Project Option” is not considered.
CHAPTER -6
ENVIRONMENTMONITORING PROGRAM
203
CHAPTER – 6ENVIRONMENTAL MONITORING PROGRAM
6.1 INTRODUCTIONThe Environmental Management Plan as presented in the previous sections for
various components of the environment needs to be monitored for its effectiveness.
Regular monitoring of environmental parameters is of immense importance to assess
the status of environment during project operations. With the knowledge of baseline
conditions, the monitoring programmed will serve as an indicator for any deterioration
in environmental conditions due to operation of the project, to enable taking up
suiTable mitigation steps in time to safeguard the environment. Monitoring is as
important as that of control of pollution since the efficiency of control measures can
be determined by monitoring.
6.2 ENVIRONMENTAL MONITORING AND REPORTING PROCEDUREM/s SLR Metaliks Ltd has set up Environmental Monitoring Cell (EMC) to review the
effectiveness of environment management system during construction and
operational phase of proposed integrated steel and other associated facilities. EMC
will work out a schedule for monitoring and will meet regularly to review the
effectiveness of the EMP implementation. The data collected on various EMP
measures would be reviewed by EMC and if needed corrective action will be
formulated for implementation.
Monitoring shall confirm that commitments are being met. This may take the form of
direct measurement and recording of quantitative information, such as amounts and
concentrations of discharges, emissions and wastes, for measurement against
corporate or statutory standards, consent limits or targets. It may also require
measurement of ambient environmental quality in the vicinity of a site using
ecological / biological, Physical and chemical indicators. Monitoring may include
socio-economic interaction, through local liaison activities or even assessment of
complaints.
The preventive approach to management may also require monitoring of process
inputs, for example, type and stocks of chemical use, resource consumption,
equipment and plant performance etc.
The key aims of monitoring are, first, to ensure that results/conditions are as forecast
during the planning stage, and where they are not, to pinpoint the cause and
204
implement action to remedy the situation. A second objective is to verify the
evaluations made during the planning process, in particular in risk and impact
assessments and standard and target setting and to measure operational and
process efficiency. Monitoring will also be required to meet compliance with statutory
and corporate requirements.
6.3 OBJECTIVES OF MONITORINGThe Objectives of monitoring are:
Verify effectiveness of planning decisions.
Measure effectiveness of operational procedures.
Confirm statutory and corporate compliance.
Identify unexpected changes.
6.4 MONITORING METHODS AND DATA ANALYSISAll environmental monitoring and relevant operational data will be stored in a
relational database and linked MIS system. This will enable efficient retrieval and
storage and interpretation of the data. Regular data extracts and interpretive reports
will be sent to the regulator.
6.4.1 AIR QUALITY MONITORING6.4.1.1 STACK MONITORINGThe emissions from all the stacks will be monitored regularly. The exit gas
temperature, velocity and pollutant concentrations will be measured. Any
unaccepTable deviation from the design values will be thoroughly examined and
appropriate action will be taken. Air blowers will be checked for any drop in exit gas
velocity.
6.4.1.2 WORK ZONE MONITORINGThe concentration of air borne pollutants in the workspace / work zone environment
will be monitored periodically. If concentrations higher than threshold limit values are
observed, the source of fugitive emissions will be identified and necessary measures
may be taken. Methane and non-methane hydrocarbons shall be monitored in work
zone. If the levels are high suiTable measures as detailed in EMP shall be initiated.
205
6.4.1.3 AMBIENT AIR QUALITY MONITORINGThe ambient concentrations of SPM, SO2, NOX, CO and HC in the ambient air will be
monitored at regular intervals. Any abnormal rise will be investigated to identify the
causes, and appropriate action will be initiated. Green belt shall be developed for
minimizing dust propagation. The ambient air quality data should be transferred and
processed in a centralized computer facility equipped with required software. Trend
and statistical analysis should be done.
6.4.2 NOISE LEVELSNoise levels in the work zone environment such as storage terminal, power
generating locations, etc. shall be monitored. The frequency shall be once in three
months in the work zone. Similarly, ambient noise levels near habitations shall also
be monitored once in three months. Audiometric tests should be conducted
periodically for the employees working close to the high noise sources.
6. 4.3 WATER AND WASTEWATER QUALITY MONITORINGTo ensure a strict control over the water consumption, flow meters shall be installed
for all major inlets. All leakages and excess shall be identified and rectified. In
addition, periodic water audits will be conducted to explore further possibilities for
water conservation.
Methods prescribed in “Standard Methods for Examination of water and Wastewater”
prepared and published jointly by American Public Health Association (APHA),
American Water Works Association (AWWA) and Water Pollution Control Federation
(WPCF); Manual on water and wastewater Analysis published by NEERI, Nagpur are
recommended.
6.4.3.1 MONITORING OF WASTEWATERAll the Wastewater streams in the project area shall be regularly monitored for flow
rate and physical and chemical characteristics. Such analysis is carried out for
wastewater at the source of generation, at the point of influent into the wastewater
treatment plant and at the effluent point for final discharge / injection into deep
ground. These data are properly documented and compared against the design
values for any necessary corrective action.
206
6.4.3.2 MONITORING OF GROUNDWATERIn order to detect any contamination of the groundwater due to leakage from any
storage tanks and other associated activities, groundwater samples shall be taken
from representative locations periodically and analyzed for necessary corrective
actions, if any.
6.4.4 LAND ENVIRONMENTThe following parameters should be monitored for land environment.
The effectiveness and constant strengthening of green belt development
should be made in and around the project site and associated facilities.
6.4.5 BIOLOGICAL ENVIRONMENT
Development of green belt with carefully selected plant species is of prime
importance due to their capacity to reduce air and noise pollution impacts by
attenuation / assimilation and for providing food and habitat for local micro and
macro fauna. This not only overcomes the problem but also enhances the beauty
of area that will attract bird and insect species and by this way ecology of the area
will maintain to great extent.
The planting of evergreen species may have certain advantages that may
reduce the environmental pollution.
Survival rate of the planted trees should be closely monitored and the trees
which not survive should be counted. Equal number of trees should be replaced
and their survival should be replaced and their survival should be closely
monitored.
Treated sewage and effluent in the best combination should be used for green
belt development. The rain water harvesting should be done. Water scarcity
should not be the reason for not expanding and strengthening green belt.
6.4.6 SOCIO-ECONOMIC ENVIRONMENT
In order to mitigate the impacts likely to arise out of the proposed project and
also to maintain goodwill of local people for the proposed project, it is necessary
to take steps for improving the social environment. Necessary social welfare
measures by the industry shall be useful in gaining public confidence depending
on local requirement.
207
Some basic amenities, viz. education, safe drinking water supply, regular
medical check up in the villages may be taken up.
Formal and informal training to be provided to the employees of the effected
villages due to the project shall be taken up on priority basis. Job oriented skill
training, courses may be organized.
Personal protective facilities like helmets, safety (gas) mask / safety dress,
shoes etc. to be ensured for all workers, engaged in operation of process units
within terminal complex.
6.5 REPORTING SCHEDULES OF THE MONITORING DATAIt is proposed that voluntary reporting of environmental performance with reference to
the EMP should be undertaken. The environmental monitoring cell shall co-ordinate
all monitoring programmers at site and data thus generated shall be regularly
furnished to the state regulatory agencies. The frequency of reporting shall be on six
monthly basis to the local SPCB officials and to regional office of MoEF. The
Environmental Audit reports shall be prepared for the entire year of operations and
shall be regularly submitted to regulatory authorities. The frequency of monitoring and
the parameters to be analysis etc. is presented in Table- 6.1
6.6 INFRASTRUCTURE FOR MONITORING OF ENVIRONMENTAL PROTECTIONMEASURESMonitoring of environmental components during operation phase is a part and parcel
of the environmental mitigation measures. Only frequent monitoring can assess the
functioning and efficiency of all pollution control equipment. Thus the project
proponent has to establish a separate full-fledged environmental laboratory to
monitor air, water, noise level in the plant. Monitoring activity is mainly envisaged for
stack emission, raw water quality, treated effluent quality to analyze the performance
of effluent treatment plant, noise level in the working areas. SLR Metaliks Ltd has
already established and managed environmental monitoring plan. This will be suitably
improved to include the additional scope defined due to the expansion project.
A well-equipped laboratory with consumable items shall be provided for monitoring of
environmental parameters in the site. Alternatively, monitoring can be outsourced to a
recognized reputed laboratory. The following equipment and consumable items shall
be made available in the site for environmental monitoring.

7.4 INDUSTRIAL HAZARDS AND SAFETYMaintenance of occupational safety and health is very closely related to productivity
and good employer-employee relationship. The plant will be operated in compliance
with all applicable safety and health laws and regulations. For occupational safety
following measures will be incorporated in the proposed plant.
7.4.1 HAZARD IDENTIFICATIONSafety Audit will be conducted by qualified technical personnel to study the
installation and activities of the industry and to suggest measures to protect
personnel and property against the risks. The areas of possible hazardous incident
are given for follow up action:
i.Fire in coal & coke storage yard, and diesel storage tanks.
ii.Electric Short circuit and consequent fire accident.
iii.Any likely sort of explosion in Boiler area
iv.Puncture of Boiler tubes.
v.Bursting of pipeline joints.
vi.Fall from high level structures
I. FIRE IN COAL & COKE STORAGE YARD & DIESEL STORAGE TANKThis may occur on account of external cause. Both coal & coke have very high flash
point and do not catch fire at normal temperatures. Coal/Coke fires are slow
progressive in nature and are controlled by simply by spraying plenty of water .
II. SHORT CIRCUIT AND CONSEQUENT FIRE ACCIDENTThe electrical short circuit may happen in any of the plant area due to poor insulation
of the equipments.
III. EXPLOSION HAZARDExplosion is expected due to bursting of high pressure equipments like boiler, turbine
and pipe lines. The water required for Boiler is pumped and transferred to the boiler
217
by using high-pressure pumps. Also the high-pressure steam generated in the boiler
is sent to the turbine through the pipeline. This pipeline will have flanged joints, with
sandwich gaskets in between for better sealing. At times, due to water hammering
this gasket fails and leads to bursting of the flange joint.

7.5 ON-SITE MANAGEMENT PLAN
The On-Site emergency plan will be circulated to all concerned members of
emergency teams. It is essential that all concerned familiarize themselves with the
overall on-site emergency plan and their respective roles and responsibilities during
and in emergency. They should also participate regularly in the mock drills that will
be conducted so as to keep themselves and the emergency organization in a state
of perpetual preparedness at all times to meet any emergency.
7.5.1 OBJECTIVES, SCOPE AND CONTENTS OF ON-SITE EMERGENCY PLAN
Objectives of Emergency Planning are to maximize the resource utilization and
combined efforts towards emergency operations and would broadly cover the
following.
1. To localize the emergency and if possible eliminate it.
2. To minimize the effects of accidents on people and property.
3. To take remedial measures in the quickest possible time to contain
the incident and control it with minimum damage.
4. To mobilize the internal resources and utilize them in the most
effective way.
5. To get help from the local community and government officials
to supplement internal manpower and resources.
6. To minimize the damage in other sections.
7. To keep the required emergency equipment in stock at right places
and ensure that they are in working condition.
8. To keep the concerned personnel fully trained in the use of
emergency equipment.
9. To give immediate warning to the surrounding localities in case of an
emergency situation arising.
10. To mobilize transport and medical treatment of the injured.
11. To educate the public in the surrounding villages regarding hazards.
12. To arrange for rescue and treatment of casualties.
13. To safe guard the people.
14. To identify the causalities and communicate to relatives.
15. To render necessary help to concerned.
16. To rehabilitate area affected.
17. To provide information to media & government agencies
219
7.5.2 SCOPE OF ONSITE EMERGENCY PLANThe plan covers information regarding the properties of the Industry, type of
disasters and disaster/accident-prone zones, the actual disaster control plans
with authority delegation, controlling and other details. General details like
location, project layout, neighboring entities and the assistance they can render etc.,
are also provided.
The important elements considered in this plan are
Statutory requirements
Emergency organization
Roles and Responsibilities
Communications during emergency
Emergency shutdown & control of situation
Rescue & Rehabilitation
Emergency facilities
Important Information
The primary purpose of the on-site emergency plan or DMP is to control and
contain the incident and to prevent them from spreading. It is not possible to cover
every eventuality in the plan and the successful handling of the emergency will
depend on appropriate action and decisions being taken on the spot. Other
important aspects needing to be considered include the following.
7.6 EMERGENCY
A major emergency in any situation is one, which has the potential to cause
serious injury or loss of life, which may cause extensive damage to the structures in
the vicinity and environment and could result in serious disruption to normal
operation both inside and outside the industry premises. Depending on the
magnitude of the emergency, services of the outside agencies may also be required
for supplementing the internal effort to effectively handle the emergency and to
contain the damage.
The Management has to take effective steps to assess, minimize and wherever
feasible eliminate the risks to a large extent. Accidents may still occur and it is
necessary to be fully prepared to tackle all such emergencies if and when they
220
occur.
It is likely that the consequences of such emergencies will be confined to the
units concerned or may affect outside. If the consequences are confined within the
plant boundary, it is then termed as On Site Emergency and will be controlled by
Chief Emergency Controller.
In order to generate the plans it is necessary to first determine the kinds of
accidents leading to an emergency that can occur in the industry. The most
widely used technique in practice is based on experience accumulated over many
years and safety audits.
7.6.1 METHODOLOGYThe considerations in an emergency planning include the following: -
1. Identification and assessment of hazards and risks
2. Hazard, consequence analysis
3. Alarm and communication procedures
4. Identifying, appointment of personnel & assignment of responsibilities
5. Identification and equipping Emergency control centre, Identifying Assembly,
Rescue points, Medical facilities.
6. Emergency preparedness plan, procedures, steps to be taken before,

7.6.3 INFRASTRUCTURE AT EMERGENCY CONTROL CENTRE
Emergency control centers should therefore contain the following
An adequate number of external telephones; if possible, one should accept
only outgoing calls, in order to bypass jammed switchboards during an
emergency.
An adequate number of internal telephones
Radio equipment
A plan of the works, to show:
Areas where there are large inventories of hazardous materials.
Sources of safety and first aid equipment.
The fire-Figurehting system and additional sources of water.
Site entrance and roadways, including up-to-date information on road Traffic.
Assembly points.
Vehicle parking and rail sidings.
Additional work and layout plans detailing alternate routes and affected
areas, during an emergency.
Note pads, pens and pencils.
A nominal role of employees.
A list of key personnel, with addresses, telephone numbers, etc.The emergency control center should be sited in an area of minimum risk.
222
SuiTable location from where clear view of the plant is possible or the control room
can be designated as Emergency Control Center. All the Site Controller/ Incident
Controller Officers, Senior Personnel would be located here or have access to the
ECC.
7.6.4 EMERGENCY MEDICAL FACILITIESStretchers, gas masks and general first aid materials for dealing with chemical
burns, fire burns, etc., would be maintained in the medical center as well as in the
Emergency Control Room. A range of medicines should be maintained in the ECC/
Medical Center. Breathing apparatus and other emergency medical equipment
should be provided and maintained.
The Medical Center should display poster for treating burns and first aid. Some
medicines and facilities to be kept in the medical center are suggested. The list is
indicative and the qualified doctors of the medical center should use their
professional judgment for medical treatment.
7.7 IDENTIFICATION AND ASSESSMENT OF HAZARDS
This stage is crucial to both on-site and off-site emergency planning and requires
systematic identification of all possible emergencies that could arise in the plants.
These should range from small events, which can be dealt by plant personnel
without any help from external agencies to the largest event that would require
outside help. To tackle such emergencies effectively, it is essential to have clear-cut
action plan. Experience has shown that for every occasion that the full potential of
an accident is realized, there are many occasions when some lesser event
occurs or when developing incident is made safe before reaching full potential.

7.9 RISK MANAGEMENT MEASURESThe risk management measures for the proposed project activities require adoption
of best safety practice at the respective construction zones within the works
boundary. In addition, the design and engineering of the proposed facilities will
take into consideration of the proposed protection measures for air and water
environment. The detailed risk management measures are listed below.
7.9.1 FURNACE
1. PREVENTIVE MEASURESIf any job is to be undertaken in EOF & BOF areas where the EOF & BOF gases
are toxic, the following procedure has to be laid down to ensure safety of men and
the equipment.
a) Gas Safety man will accompany the team and will test the atmosphere for
the presence of CO, before starting the work.
b) If `CO' concentration is found exceeding the safe limit, the job will be
undertaken using necessary safety appliances viz., Oxygen Breathing
Apparatus/ Blower type Gas mask.
c) Any gas cutting/welding job will be undertaken with the clearance from Gas
Safety man.
2. GAS EXPLOSION, PREVENTION & PREVENTIVE MEASURESThe following actions will be taken to prevent any gas explosions in case of gas
leakage.
1. For jobs on gas lines/equipment, non-sparking copper tools will used. If such
tools are not available, grease coated steel tools will be used. Electrical drill &
other electrical equipment will not be used as these can give rise to sparks.
2. The gas line will be thoroughly purged with steam before undertaking the job
on the same.
3. Naked lights will not be used near any de-pressurized gas main or equipment
unless the same has been thoroughly purged.
4. In case of profuse leakage of gas, action will be taken for water sealing
and isolating that portion.
5. The approach road to the gas line complex will be kept free from any
obstructions.
228
6. If gas catches fire due to some leakage, it will be extinguished with plastic
clay, steam or water. The portion of gas main affected will be cooled down with
water. The valve will not be closed when fire is still there and the pressure in
the main will be maintained at minimum 100 mm (WC).
7. Gas tapping points of flow or pressure measurement will be cleaned with
wooden stick or grease coated wire.
8. If lighting is necessary near gas line, porTable spark proof electric lamps of
low voltage or explosion proof torchlight will be used for enclosed areas.
7.9.2 HOT METAL & SLAG
Sudden break out of molten metal & slag may result in heavy explosions, due to
their coming in contact with water, thereby causing serious burn injuries to persons
and damage to equipment.
1 PREVENTIVE MEASURES1. Any accumulation of water will be prevented in such vulnerable areas.
2. In case of minor leakages, the flow of molten metal & slag will be controlled.
3. If there is major breakout, the area will be cut off and cordoned.
4. Vital connections e.g. water, gas, compressed air, oxygen etc. will be cut off or
regulated, as per requirement.
Fire water sump and its details are explained in the earlier chapters.
7.9.3 RESPIRATORY HAZARDS1 DUST AND GASESDust generated in integrated pig iron complex includes iron and metallic dusts,
which are mainly present in BF, continuous casting buildings and sinter plants; and
mineral dusts which are mainly present in raw material storage, BF. In the former
case, workers may be exposed to iron oxide and silica dust that can be
contaminated with heavy metals such as chromium (Cr), nickel (Ni), lead (Pb), and
manganese (Mn), zinc (Zn), and mercury (Hg). The most significant is the dust
present in the melting and casting processes (e.g. BF, continuous casting), where
the dust, which is generated by high temperature operations, is finer and more
easily inhaled than in the rolling processes. In raw material storage, blast furnace
and coke oven plant, workers are exposed to mineral dust, which may contain
heavy metals. In addition, BF tapping results in graphite release.
229
In the melting and casting processes where high temperature operations are
conducted, workers may be exposed to gas inhalation hazards, which may
contain heavy metals. In the BF, workers may be exposed to gas inhalation hazards
of carbon monoxide. To prevent exposure to gas and dust, the steps taken
include the following:
Sources of dust and gases will be separated and enclosed;
Designing the facility ventilation to maximize air circulation. Outlet air will
be filtered before discharge to the atmosphere;
Exhaust ventilation will be installed at the significant point sources of dust and
gas emissions, particularly the BF topping area
Providing a sealed cabin with filtered air conditioning if an operator is
needed in a contaminated area;
Providing separated eating facilities that allow for washing before eating;
Providing facilities that allow work clothes to be separated from personal
clothes, and for washing / showering after work;
Implementing a policy for periodic health checks.
Respiratory hazard control technologies will be used when exposure cannot be
avoided with other means, such as manual operations such as grinding or use of
non-enclosed machine-tools; and during specific maintenance and repair operations.
Necessary steps/ precautions for respiratory protection include the following:
Use of filter respirators when exposed to heavy dust (e.g. fettling works);
For light, metallic dust and gases, fresh-air supplied respirators will be
used. Alternatively, a complete facial gas mask (or an “overpressure”
helmet) may be used, equipped with electrical ventilation;
For carbon monoxide (CO) exposure, detection equipment will be installed to
alert control rooms and local personnel. In case of emergency intervention in
areas with high levels of CO, workers will be provided with porTable CO
detectors, and fresh-air supplied respirators.
7.9.4 HEAT AND HOT LIQUID
High temperatures and direct infrared (IR) radiation are common hazards in pig iron
complexes. High temperatures can cause fatigue and dehydration. Direct IR
radiation also poses a risk to sight. Potential contact with hot metal or hot water may
occur from the cooling spray zone of continuous casting, from splashes of melted
230
metal, and from contact with hot surfaces. Precautionary measures for prevention
and control of exposure to heat and hot liquids / materials include the following:
Shielding the surfaces where close contact with hot equipment or
splashing from hot materials is expected (e.g. blast furnaces, BOF, continuous
casting and heating oven, and ladles);
Implementing safety buffer zones to separate areas where hot materials
and items (e.g. billets, thick slabs, or ladles) are handled or temporarily stored.
Rail guards around those areas will be provided, with interlocked gates to control
access to areas during operations;
Using appropriate PPE (e.g. insulated gloves and shoes, goggles to protect
against IR and ultraviolet radiation, and clothing to protect against heat radiation
and liquid metal splashes);
Installing cooling ventilation to control extreme temperatures;
Implementation of work rotations providing regular work breaks, access to a
cool rest area, and drinking water.
7.9.5 PHYSICAL HAZARDS
Precautions for the prevention and control of general physical hazards are
presented below.
Potential physical hazards in pig iron complex operations are related to handling of
large and heavy raw materials and product (e.g. blast furnace and storage and
movement of billets and thick slabs, movement of large ladles containing molten
metal); heavy mechanical transport (e.g. trains, trucks and forklifts); grinding and
cutting activities (e.g. contact with scrap material ejected by machine-tools); and
work at heights (e.g. platforms, ladders, and stairs).
7.9.6 HEAVY LOADS / GRINDING & CUTTING / ROLLING
Lifting and moving heavy loads at elevated heights using hydraulic platforms and
cranes presents a significant occupational safety hazard in pig iron plant. Measures
taken to prevent and control potential worker injury include the following;
Clear signage in all transport corridors and working areas;
Appropriate design and layout of facilities to avoid crossover of different
231
activities and flow of processes;
Implementation of specific load handling and lifting procedures,
including:
o Description of load to be lifted (dimensions, weight, position of center of
gravity)
o Specifications of the lifting crane to be used (maximum lifted load,
dimensions)
o Train staff in the handling of lifting equipments and driving mechanical
transport devices
The area of operation of fixed handling equipment (e.g. cranes, elevated
platforms) will not cross above worker and pre-assembly areas;
Material and product handling will remain within restricted zones under
supervision;
Regular maintenance and repair of lifting, electrical and transport equipment
will be conducted.
Prevention and control of injuries related to grinding and cutting activities, and use
of scrap, include the following:
Locating machine-tools at a safe distance from other work areas and from
walkways;
Conducting regular inspection and repair of machine-tools, in particular
protective shields and safety devices /equipment;
Training staff to properly use machines-tools, and to use appropriate
personal protection equipment (PPE).
7.9.7 MUSCULOSKELETAL DISORDERSMusculoskeletal disorders are injuries that affect muscles, tendons, ligaments
and nerves. These injuries can develop when the same muscles are used over and
over again or for a long time without taking time to rest. The chance of getting this
type of injury increases if the force exerted is high and/or the job requires an
awkward posture. Some examples of musculoskeletal disorders include back pain,
carpal tunnel syndrome, tendonitis and tenosynovitis.
Preventing musculoskeletal disorders requires recognition, assessment and
control of the hazards that cause them. Keep in mind that the most knowledgeable
person about problems with a job is usually the person doing it.
232
7.9.8 CONTROL HAZARDS, PREFERABLY AT THEIR SOURCEConsider changes to
Mechanizing a repetitive task or process
Designing workstations and work processes using ergonomic principles
Using well maintained tools and equipment that decrease force or
awkward position
Providing lifting devices to eliminate heavy lifting
Ensuring that all employees receive comprehensive training on how to do
their job safely
Using ergonomic principles, to avoid
Awkward body positions
Overextended and awkward reaches
Repetitive or heavy bending, twisting, reaching, lifting, lowering, pushing and
pulling
Sustained or static exertions
7.9.9 NOISENoise is not a new hazard. It has been a constant threat since the industrial
revolution. Too much noise exposure may cause a temporary change in hearing
(your ears may feel stuffed up) or a temporary ringing in ears (tinnitus). These short-
term problems usually go away within a few minutes or hours after leaving the noise.
However, repeated exposures to loud noise can lead to permanent, incurable
hearing loss or tinnitus. Removing hazardous noise from the workplace whenever
possible and using hearing protectors in those situations where dangerous noise
exposures have not yet been controlled or eliminated.

7.12.5 EMERGENCY ACTION PLAN FOR MEDICAL AID
I. EMERGENCY ACTION PLAN FOR ELECTRIC SHOCK CASUALTIESELECTRIC SHOCK RESULTS IN
Irreversible damage to brain cell begins followed by deterioration of the organs.
238
RESCUE AND FIRST AID
Do first aid quickly and without fuss and panic
Switch off the supply if this can be done at once.
If not possible use a dry stick, dry cloth or other non-conductor to separate
the victim from electrical contact.
The rescuer must avoid receiving shock himself by wearing gloves or using a
jacket to pull the victim.
Always keep in mind that delay in rescue and resuscitation may be fatal.
Every sound counts.
ii. ARTIFICIAL RESPIRATIONGive artificial respiration if breathing has stopped. There are several methods
of artificial respiration, if the victim is not injured over the face, try mouth to
mouth.
a. MOUTH TO MOUTH METHOD If there is obstruction to breathing, remove it with your fingers if it in mouth.
Several sharp blows between shoulder blade may help to is lodge an obstruction.
Lay casually on his back, put something under his shoulder to raise them &
allow his head to fall backwards. The head should be, if possible be a little
lower than the trunk. Remember that speed is essential.
Kneel at the causalities head and grasp his arms at the wrists then cross
them firmly over the lower chest. This movement should force air out of his
lungs. Press with the hands crossed on the lower part of the chest and maintain
pressure for two seconds.
Release this pressure and pull out his arms with a sweeping movement
upwards and outwards above his head and backwards as far as possible.
This movement should cause air to be drawn in to his lungs. Retain the
arm in this position for three seconds.
Repeat these movements rhythmically about twelve times a minute checking
the mouth frequently for obstructions. Each cycle will thus take give seconds-
two seconds for chest pressure and three seconds for arm lift.
With the causality on his back there is danger of aspiration of vomit,
mucus or blood reentering the system. This risk can be reduced by keeping his
239
head extended and a little lower than the trunk.
If an assistant is available, he can press the causality lower jaws so that the
chin is jutting out.
The assistant should also ensure that the mouth is kept open as far as
possible and head is tilted to one side.
When natural breathing begins, your movement should be adapted to
correspond to it.
If burns are present, cover them with a dry sterile dressing
Handle the causality gentle.
Do not allow people to crowd around and block fresh airflow.
Arrange to remove the injured to the care of a doctor as early as possible.
7.13 NATURAL HAZARDS7.13.1 EMERGENCY ACTION PLAN FOR TORNADO/HIGH WINDS
a. Weather reports will be monitored from broadcast warnings regarding
threatening conditions.
b. If the tornado has been sighted or effect is felt, following steps should
be taken by plant personnel.
Persons will be notified over public address system or through siren.
Emergency services will be alerted for assistance.
Plant personnel should be advised to assemble in the
administration building basement, staff room, recreation room and rest
rooms.
All safety systems should be kept on alert and all nonessential
utilities should be put off.
c. After the status is restored, personnel should inspect all the facilities for
resource, first aid and damage control activities, damage assessment, and clean
up, restoration and recovery.
7.13.2 EMERGENCY ACTION PLAN FOR EARTHQUAKESa. When first tremors are sensed during an earthquake, all personnel should
evacuate buildings and assemble at safe place away from structures, walls
and falling objects. Emergency shutdown should be declared.
b. Emergency services should be contacted for assistance.
c. After the status is restored, personnel should inspect all the facilities for
240
rescue, first aid and damage control activities, damage assessment, cleanup,
restoration and recovery.
7.13.3 EMERGENCY ACTION PLAN FOR BOMB THREAT When bomb threat call is received the following measures are to be taken.
Inform the message to the highest local police authority and seek their
assistance for patrolling and security need.
Inform Controller of Explosives the details and nature of the anonymous
message and read operations.
Request the Local Fire Brigade to position at least on fire tender at the
Location immediately.
Keep the Concerned Department at the Regional Level informed with the
developments at regular intervals.
Alert the Local Government / Private Hospitals and seek their help for
providing Ambulances if necessary
IN THE LOCATION PREMISES Keep the Fire Hydrant System/all Fire Figurehting and Personnel protective
Equipment in readiness.
Every one entering the Location must be frisked at the Gate/check all
Hand Bags, Parcels etc., for suspected explosive/dangerous objects.
Have thorough inspection of the Location for any suspected dangerous
object.
Materials and other Boxes to be brought in to the Location must be
deposited at Gate for minimum curing period of 48 Hrs.
Organize Employees Vigilance cell for round the clock observation of
industry Premises.
IF THE SUSPECTED OBJECT IS FOUND In case of finding of suspected Article, do not disturb its position, but the area
around it should be cordoned off to a distance of 100 meters and more
depending upon the gravity of situation.
Adequate Staff or Police Squad posted to prevent any unauthorized entry into
the enforced cordon.
Contact Controller of Explosives immediately, who on reaching the Site will
241
decide suiTable action for defusing and disposal of the suspected object.
Evolution of thick billowing smoke is an indication of impending explosion and
in such a case, with draw or evacuates all personnel from the spot, which has
been identified.
As a general measure regulate the movement of the outsiders inside our
Premises and restrict their entry with permits.
7.14 SOCIAL IMPACT ASSESSMENT, R & R ACTION PLAN
7.14.1 EXISTING SOCIAL STATUSIt is proposed to describe the existing social status in as to demography, amenities,
public health, agriculture, land-use pattern, employment and industries.
1. POPULATION
The decadal growth in the State is 15.67% which is comparable with
general corresponding national Figures (17.64%). However Bellary district
shows a growth rate of 20.38%.
The male female ratio of H.B.Halli taluk is 975 females for 1000 males
which corresponds to the national average of 975 females for 1000 males.
Total literacy rate in Bellary district is 68%. However the literacy rate in
H.B.Halli taluk is only 58.58%%. The literacy rate is better in male than in
female.
2. TRANSPORTATION & COMMUNICATIONAll villages in the study zone are connected by road network. However surfacing
needs to be improved. The establishment of this industry is catalytic to the road
development.
3. PUBLIC HEALTHThe villages in the study zone facilities are scanty. Few have some semblance of
health centre, in others visiting practitioners visit. A Government Hospital is present in
H.B Halli.
4. AMENITIES IN STUDY AREAIt is peculiar that all the villages are inhabitated. The information compiled by
record and interviews is as follows:
242
In absence of any commensurate industrial development, agriculture is the
only source of livelihood.
Primary school education is available in all the villages.
Drinking water is available to all the villages, the source being open dug
well/borewell with or without pump/electricity.
It is encouraging to find that all the all the villages are connected by road
network, though it needs good surfacing. This is a good infra- structure for
bringing cane from the villagers and they will get benefited.
7.14.2 ECONOMIC STATUS IN THE REGION: LAND USE PATTERNAGRICULTUREThe cropping pattern in the district reveals that food crops like paddy, maize, bajra and
sorghum among cereals, red gram, bengal gram and green gram among pulses are
major crops cultivated in the district. The major oilseed crops are sunflower, groundnut
and safflower. Horticulture crops like banana, mango, citrus, pomegranate, Figure,
grapes are also grown. A recent trend shows that there is a low shift towards fruit
crops like pomegranate and grapes. Of the total area of 8,610 square kilometers
covered during 2002-03 cereals occupy about 55.2% by oilseeds 24.5% pulse 15.6%
and other commercial crops like cotton and sugarcane about 4.8%. There is a slight
shift towards commercial crops like cotton and sugarcane over last 2 years.
IRRIGATIONThe individual land holding is small. Irrigation and communication facilities are
scanty. Only 17.3% of the net cultivable area is irrigated and the balance 82.7% of
the area has to depend on the monsoon. This tehsil is in Tungabhadra basin and
hence have a relatively better situation of support by man-made efforts of wells, river
impoundment or tank for irrigation, though only one crop is possible. In spite of this
difficult situation, a large percent are supported by cultivation.
ANIMAL HUSBANDRYThe people are turning to mechanical engineering means both for agriculture as well
as for transport. The cattle population density of the District is moderate to low and it
is reflected in the persons employed in this sector. It may be found that in Influence
zone area, the percent is less than 1% who are dependent on livestock.
All this leads to one conclusion that industrialization has to be stepped up
243
To provide more livelihood.
To provide male employment with women participation, for economic
independence.
To improve agriculture by increasing the spending capacity of the
people by other avenues and diverting the gains.
To improve livestock census per sq. km by utilizing employment gains.
Employment & wages:
The information related to this is tabulated below:
Table-7.6 Comparative Occupations
Sl. No. Particulars District Level Study Zone1 Main workers to total population,
%
26.06 43.182 Marginal workers to total population,
%
2.52 8.213 Non-workers to total population,
%
71.41 48.59
AS WOULD BE SEEN FROM THE TABLE Maximum employment is in the agricultural sector only. Here there are two
classes, one who own the land and cultivate by themselves, and two who are
employed as workers on others’ fields.
In Agricultural sector women participation is insignificant in
cultivators class, which means women do not have much economic
independence.
The number of people not having any source of revenue is substantially high.
The marginal workers too do not get satisfactory duration of employment in
the year.
HERITAGEThe study zone does not have archaeological, monument, defense installation,
airport, hospitals, ports, national park, religious places, resorts or other historical
places within 10 km area.
7.14.2.1 REHABILITATION & RESETTLEMENT PLANThe expansion project is proposed to be developed in an un-inhabited open barren
land. The vegetation in the area is scanty and is only bushes and shrubs. In view of
the above, the proposed expansion project does not involve any displacement of
persons and no rehabilitation or resettlements is necessary.

CHAPTER 8PROJECT BENEFITS
8.1 IMPROVEMENTS IN PHYSICAL INFRASTRUCTURE
The physical infrastructure of this area will improve due to various activities of the
proposed project as enumerated below.
8.2. SITE AREA IMPROVEMENT
190 acres of additional land adjacent to the existing project site is allocated through
KIADB for establishment of the proposed expansion project. The site area is
proposed to be extensively used for landscape development. Storm water gutter,
water reservoir and rain water harvesting will be provided in the premises. This will
improve water Table in the area. The enhanced groundwater source will be useful to
the surrounding farmers who mainly depend on groundwater for irrigation.
Also nursery will be developed keeping the concept of bio-diversity in mind to meet
the tree plantation needs of the industry and surrounding villages. Greenery and green
belt covering 33 % of the total area will be developed. Lawns and associated
ornamental tree hedges will be developed around plants, buildings, parking and,
storage area. Line trees will be planted on either side of the roads present in the
premise and in the vicinity of the site.
The industry is dependent on roads for transportation of men and material. Road
connectivity will improve. Vehicular movement for raw materials and products and
also for the movement personnel in the roads of this area will considerably increase.
This will result in development and maintenance of roads. Automobile related activity
such as vehicle repair and maintenance garages, workshops and shops will be
started. The location is rural and economically backward. The industry will lead to
creation of new job opportunities and scope for transport and other petty business
activity.
This improved physical infrastructure will be an added facility to the community
for surface transport.
245
8.2.1 INDUSTRIAL AREA (PROCESSING AREA)/ RESIDENTIAL AREA (NONPROCESSING AREA)
The industrial processing premise will be provided with internal roads, road side
gutters, Storm water gutters, sewage lines, Street lights, Flood lights, Parking area.
Landscaping, lawn and greenery will be developed in the premise.
Rain water harvesting and rain water reservoir of adequate capacity will
be built.
Fire Figurehting and disaster management facility will be provided.
8.2.2 GREEN-BELTGreen belt and greenery will be developed in about 65 acres of land. The species
developed will be as per CPCB guide lines. Assistance and guidelines will also be
availed in development of greenery in the industry.
All the premise green belt of about 20 m will be developed. Trees will be developed
on either side of the internal roads as well on all approach roads to the industry,
Lawns will be developed around plant and administrative buildings. Green belt of 10
to 20 m will be developed around open bulk storage yards.
8.3 IMPROVEMENTS IN THE SOCIAL INFRASTRUCTURE
The location is rural and economically backward. Creation of job opportunity and
scope for transport, civil works and supply of material and services and other petty
business activity associated to the project will improve. With this the economic status
and purchasing power of public will improve. This will result in improved attitude of
the public towards education and health. This may cause in creation of education and
health care facilities in this rural area.
It will not disturb the existing pattern of social relations and democratic setup.
In rural areas much of the time and energy is wasted in reaching from one place to
another. This is due to lack of swift mode of transport. By the establishment of this
industry, movement of vehicles in this area will generally improve (both private and
public-owned).
With establishment of the In the study zone of 10 km radius, the purchasing power of
people is very less. The agricultural implements, agro-chemicals and vehicles will be
246
in more demand as also village grown milk products, vegeTables and agricultural
produce.
Present level of education and literacy (especially rural and women) is very poor and
it needs improvement. The establishment of this industry will play a catalytic role in
this. Education level will go up with flow of funds and avenue of livelihood. Likewise
the healthcare facilities are also said to improve.
Living in harmony is an important aspect of the society. This can happen only if all
the components are comfortably placed. Persons engaged in their respective
vocation and accruing job satisfaction leads to this. This will become possible by this
venture.
The improvements in social infrastructure are discussed below
8.3.1 CONNECTIVITYA good quality tar road will be developed from the site to to S.H.Way-25. The S.H.-
25 connected to N.H.-13 near Mariammanahalli in NE and N.H. 4 at Harihar in South.
Existing Tarred road to join the site to S.C. railway station at Vyasanakere. Will also
be up graded.
8.4 EMPLOYMENT POTENTIAL – SKILLED, SEMI-SKILLED AND UNSKILLED
The industry and its supporting activities need people from manual to managerial
strength. The production activities, transportation, maintenance of machineries and
civil works associated with the project will need unskilled and skilled workers. people
on tractors and tractor repairers as skilled ones. So in manufacturing activity all three
types i.e skilled, semi-skilled and unskilled people are required. The overall potential
including the garages, loading-unloading actions, eateries, small shop owners is
substantial. The local people can get a good share out of this. In the factory, science
and technology prevails and there some outsiders will have to be engaged at least for
the time being. If the second generation local people acquire that skill, they too will be
able to fill the gap and accrue benefit of higher jobs. If the activity of sugar and
alcohol manufacturing becomes sTable by that time, perhaps expansion may become
possible further and then employment availability may further enhance.
247
The total direct employment potential of the proposed industry is about 450 people.
However, the commencement of this industry will create direct and indirect
employment opportunities to more than 2,000 people in terms of factory employment,
transportation, vehicle maintenance, petty shops etc.
10.4.4 AESTHETIC (NOISE & ODOUR) ENVIRONMENTThe Project will generate noise from various locations like
Steam Generator
Rotary equipments like fans, blowers and compressors
Combustion Chamber Steam traps and leaking points The proponent note

10.5 ENVIRONMENT MANAGEMENT HIERARCHY
Developer is aware that environmental management is not a job, which can be handledwithout a careful planning. The success lies if three components are simultaneously presentviz. (1) management support, (2) efficiency of the environment management cell and (3)acceptability of resulting environmental quality, both by SPCB and by public. A structure ofthis plan and hierarchy of process flow for environmental management is prepared andenclosed as logics, which is self-explanatory. Developers will adopt this structure andhierarchy, which is akin to principles and practice.
10.6 CHECKLIST OF STATUTORY OBLIGATIONSThere are a number of environmental status required to be attended to by the industries or
projects. Industry has prepared a checklist of these obligations, which facilitates the
obedience of the laws of land. These are advised to industry as follows:
1 The Consents, whether under the Water Act or under the Air Act, are normally issued
for a fixed validity period. Please check whether the Consent is valid. If the same is
expiring, it is better to apply for a fresh renewal at least 120 days prior to the expiry date.
2 The Consent normally describes the items of manufactured products with
quantity.One should see that, the described framework is not overstepped. In case, there
is any likely hood of such increase, it will be worthwhile to obtain permission for the same.
At least a letter to that effect be posted to the relevant board officer.
3 The Consent lays down a condition as to the volume and rate of discharge of
effluents both for domestic as well as the industrial activity. By routine checks at the
measuring devices, this can be ascertained.
4 There should be a continuous performance evaluation of the treatment units like
257
STP, so as to always remain inside tolerance limits. Following measures can be
adopted,
a. Characterization of raw effluents/emissions.
b. Attempting in-plant controls.
c. Operation, maintenance, repairs and replacement of the STP,
d. Retrofit equipment to the existing plant.
5 Disposal is the last ditch battle. Disposal, dispersion, dilution, diversion, therefore, has
to be planned very methodically and operated efficiently. This is a place where more
reliable staff is required to be deployed.
6 The drainage network has been planned in such a way that, storm water and
effluents do not get mixed. Keep the terminal manhole clean and always hospiTable to
facilitate taking of sample by the Board officials. Also check that no effluent is admitted in
the channel down-stream of the terminal manhole, which means all the effluent, finally
should pass via the terminal manhole only.
7 Monitoring aspects are always very crucial. For operating the plant, certain
parameters be constantly checked. However, it will be a good practice to check monthly
all the parameters through standard and approved laboratories. In case there is a
water body in the vicinity, it is advised to take periodically samples from it. This applies
both to the surface water as well as ground water. The findings will either give you a
confident satisfaction or may give you a timely warning for improvement in the treatment
or more so in the disposal system.
8 The environmental audit statement is required to be submitted on annual basis,.
9 The industry should device their own format for a daily log book recording of the
running of their STP. A printed format shows your conscious efforts towards the goal of
pollution control, whenever any inspection takes place.
10 An inspection book to note observations made by the visiting KSPCB field officer is
maintained. The compliance of the unsatisfactory remarks are shown during next
inspection.
11 In case, there is an unfortunate accident, unforeseen act or event by which pollutants
are excessively released into the environment, the same to be brought immediately to the
notice of the board and other concerned agencies. This will enable you to get
experienced timely help from them. Your burden gets shared. Synergistic effects can be
predicted by an overview.
258
12 In case, you feel aggrieved by any conditions imposed in the Consent, approach the
board immediately for discussion, or thereafter prefer an appeal timely. Therefore, read
the Consent carefully as soon as you receive the same.
13 The Water Cess Act, 1977, is applicable to certain specified industries. In case your
industry is covered, the regular returns to be submitted. Water meters be installed,
whether the industry is covered or not under the Cess Act. Also check from time to time
whether the class of your industry, which may not be presently specified, has since got
covered under the Cess Act.
14 The Cess amount be paid as per assessment orders and record maintained.
15 In case you feel aggrieved by excessive cess assessment or non-sanction of rebate,
the appeal is preferred in time that is within 30 days. And in case, you are late in doing
this, at last submit with reasons for the delay.
16 The Government or Board while giving site clearance or Consent normally puts a
condition of plantation of trees. Otherwise also, planting trees within the compound gives
a good demonstration of your plant performance. A better practice is to select about three
varieties and species selected to be tough and tolerant for existing type of environment.
17 An unsafe working and the environmental pollution generally goes hand-in-
hand.Therefore, the obligations under the Factories Act be scrupulously followed and
record maintained.
18 There are certain responsibilities regarding the hazardous waste. These can be
summarized as follows: a) Identification of quantity, constituents and compatibility of
hazardous waste, being generated during the activity.
a. Proper labeling and marking of containers, which are used for store, transport, or
disposal of hazardous waste.
b. Use of appropriate containers for storage and transport.
c. Furnishing of information regarding the waste, its nature, its hazards, antidotes, and non-
compatibility etc. to the persons who either transport, treat, store or dispose off the waste.
259
d. Use of authorized operator agency system to ensure the proper disposal of
hazardous wastes (i. e. used oil) and to streamline the treatment and disposal.
e. Training of personnel for handling and proper storage of such categorized waste.
f. Identify a transporter specialized in such wastes, and the practice of hexplicate
manifest (gate-pass) be followed.
g. Submission of reports to MOEF and KSPCB.
h. To provide safety measures for handling of hazardous waste.
i. In case of an unforeseen act or event in transit occurs, the transporter should
Immediately report to the nearest police station about The accident, and The clean- up
measures.
j. He should also report to SPCB on the Form prescribed by the Hazardous Waste
(Management and Handling) Rules, 2008 and the guidelines issued by the Central
Government.
k. A container be opened for a short duration while receiving the hazardous material in it
and while removing out from it, or otherwise it must always be kept closed in storage
yard.
l. A container be opened or handled so carefully and slowly as not to rupture/damage the
container. Always keep in spare some empty, clean and sturdy containers handy and
immediately available.
m. Inspect the filled and stored containers every day and if any found in bad
conditions transfer the contents to a good container immediately but carefully.
n. Keep a daily record of your custody.
o. Documentation is always a matter of evidential value. No job is complete unless
paper work is complete. Occupier/generator should carefully note this, and following be
developed.
p. Gate-pass when waste leaves the factory by a transport towards the treatment
facility. Keep the receipts.
q. A receipt of material as signed by the facility Operator as a manifested colour coded
copy is preserved for three years.
r. Analyze the out-going waste and keep the results for three years from the date of
dispatch.
260
10.7 RECORDS OF WASTE GENERATION TO BE MAINTAINED AS PER FOLLOWING

Occupier is best advised to inform the concerned authorities and agencies, as to his
preparing documents like risk analysis, emergency plan, safety training, avoidance of
major accidents, health plan, etc.
2. Under the Public Liability Insurance Act, 1991 the industrial manager is advised
to check some important activities, such as
a. Owner should take out one or more insurance policies.
b. He should take out such policies before he starts handling any hazardoussubstances.
c. The policies should always be kept renewed and alive.
d. The amount insured shall not be less than the paid capital. Check this from time totime by taking a review of your position.
e. General Insurance Corporation or similar agencies may be able to throw more light, ifapproached.”

10.11 STEERING COMMITTEE
A high power steering committee is in place having a power of sudden spot
inspections, checking of documents and listening to complaints if any. This committee
will supervise over the monitoring and environmental management cell as may be
necessary, generally over the following facets of works:
265
1. Permit management
2. Construction management
3. Treatment and emission management
4. Transport management
5. Disposal management
6. Monitoring
7. Documentation
8. Law enforcement
9. Customer and Third party audits
10. Following CII Model of excellence
10.12 CONSTRUCTION PHASE MANAGEMENTIn this particular case, this phase is very important. It will continue for a long
time, in the developmental stage. The component will commence from site
preparation.
1. SITE PREPARATIONThe clearance of site may involve the movement of soil. No major leveling
operations are envisaged, though at places this will be encountered. During dry
weather conditions it is necessary to control dust nuisance created by excavation
and transportation activities. Else at some sensitive locations, water sprinkling will
be resorted to.
2. SANITATIONa. LABOUR CAMPSThe construction site shall be provided with sufficient and suiTable toilet facilities
for construction workers to allow proper standards of personal hygiene. These
facilities shall be connected to a septic tank and maintained to ensure minimum
or no environmental impact. Water taps will be provided in the labour camps, but
it will be seen that spilled water will be directed towards collection sump first and to
the treatment scheme next.
b. NOISEThough the noise effect on the nearest inhabitants due to construction
266
activity will be negligible (as at present there are no residents to begin with), it is
advisable that on site workers using high noise equipment adopt noise protection
devices like earmuffs. Noise sources are heavy earth moving and construction
machineries, air compressors and D.G Sets. Proper oiling, maintenance, non-
vibrating sturdy foundations and closed rooms shall be provided to minimize the
effects.
c. CONSTRUCTION EQUIPMENT AND WASTEIt shall be ensured that both gasoline and diesel powered construction vehicles
are properly maintained to minimize smoke in the exhaust emissions. The vehicle
maintenance area shall be located in such a manner to avoid sources by
accidental spillage of oil. Unauthorized dumping of waste oil should be prohibited.
Wastes shall be disposed off at an approved site.
d. STORAGE OF HAZARDOUS MATERIALThe following hazardous materials may be used for site preparation and
construction activity.
These shall be stored as per international standards.
1. Explosives for rock blasting (This is not proposed)
2. Petrol and diesel
3. LPG
4. Painting materials
5. Asbestos products are avoided.
e. SITE SECURITYConstruction site is a potential hazardous environment. To ensure that the local
inhabitants and stray cattle are not exposed to these hazards, the site shall be
secured by fencing and manned entry points. It will be fully illuminated.
f. LAND ENVIRONMENTAn inventory shall be prepared of standing trees and bushes of significance. To
prevent unauthorized felling of trees by construction workers for their fuel needs
it will be ensured that the contractor provides fuel to them. The construction
workers will be educated on importance of maintaining the existing tree.
CHAPTER -11
SUMMARY ANDCONCLUSIONS
267
CHAPTER – 11SUMMARY AND CONCLUSIONS
M/s. SLR Metaliks Ltd. propose to improve the viability of the existing project by the
addition of facilities for the production of value added downstream products with
ready market opportunity such as alloy steel, rolled steel products, metallurgical coke,
coke oven gas based power and oxygen in the existing Iron making industry. The
expansion does not require additional ore. The steel industries in general are on
priority list as they contribute in overall development of the country. Integrated steel
industries in particular will produce steel and steel products at economic cost and
also has export potential to earn/save foreign exchange.
i. Additional land needed to the project is already allotted by KIADB.
ii.The proposal is for manufacture of downstream and associated products. This
will reduce transportation and operation cost and result into overall economy
and viability of the industry. Coke oven off gases are advantageously utilized in
the power generation for captive use.
iii. The product mix includes Steel alloy from steel plant, TMT bars from
rolling mill. Based on market demand and pricing capacity utilization of these
plants can be varied.
iv. Metallurgical coke from coke oven plant will be utilized as captive
source in the existing BF plant. Coke oven off gases will be used in waste heat
recovery boiler for generation power. The power thus generated will be used in
the industry as a captive source.
v. Water requirement will be met within the available permissible limits
from the river source.
vi. This industry does not produce any toxic products and does not have
significant adverse effect on the quality of land, water and air. The industry has
taken all the necessary preventive measures to mitigate even the small effects
which might be caused by industrial activities.
vii. Gaseous emissions will be generated from furnaces, boiler, fume
exhaust will be treated in suiTable APC system and vented through the stacks of
adequate height.
viii. The concept of Reduce, Reuse and Recycle is also practiced in the
industry as per the eco-policy of Govt. of India. This will result in high
performance, and minimal resource utilization. With the addition of steel making
units energy savings of 405 KWH/ton of pig iron will be saved as it avoids re-
melting of pig iron.
268
ix. Wastewater generated in the industry will be treated and re used for
industrial purpose and green belt and greenery development in the factory
premise.
x. The industry will adopt an effective environment management system
and environment management plan to protect the environment. Due priority will
be given for greenery development and rain water harvesting at the factory
premises.
xi. The site is connected to supply of raw material and product utilizers
through well laid national and state high ways and railway lines. The traffic on
these lines is with in the permissible limits.
PROJECT FEASIBILITY AS A SUSTAINABLE DEVELOPMENT MODEL This project is very essential in-view of production of high value downstream
products.
The local people desire the setting up of the industry to create additional direct
& indirect job opportunities as well as business opportunities.
Water, power, Raw material and Market are available.
Adequate precautions will be taken for Pollution Control, Resource
Conservation and Environmental Protection.
This is cost effective and aims Sustainable Development.
The project is proposed in economically & industrially backward / rural area of
Karnataka State.
