4.2 CONSTRUCTION PHASE
Air Environment
Impact on Air Quality
During construction phase, dust will be the main pollutant, which will be generated
from the site development activities and vehicular movement on the road. Further,
concentration of NOx and CO may also slightly increase due to increased vehicular
traffic. However, change in ambient concentrations of air quality will be insignificant
and temporary. As most of the construction equipment will be mobile, the emissions
are likely to be fugitive. The impacts will be localized in nature and the areas outside
the project boundary are not likely to have any significant adverse impact.
Air Pollution Control Measures
During dry weather conditions, it is necessary to control the dust generated by
excavation and transportation activities. This will be achieved by regular water
sprinkling. Ambient air concentrations of SO2 and NOx are expected to increase due to
operation of construction machineries such as bulldozers, pay loaders, trucks etc. These
levels are expected to be insignificant as these machines will be operated intermittently
and only day time. Most of the equipment and machineries will be mobile and hence, the
emissions will be mostly fugitive. It will be ensured that vehicles and machineries are
properly maintained to minimize smoke in the exhaust emissions. Additional air
pollution control measures include the following:

Chapter 4:Anticipated Environmental
Impacts & MitigationMeasures

• Sprinkling of water at regular intervals preferably using truck-mounted sprinklers
along the roads and work zone areas;
• Electrical power shall be made available near to the site. Attempts to be made to
utilize the electrically powered machinery to the extent possible to minimize the
emissions of SO2 and NOx.
Noise Environment
Impact on Noise Levels
The major sources of noise during the construction phase are vehicular traffic,
construction equipment like dozers, scrapers, concrete mixers, cranes, pumps,
compressors, pneumatic tools, saws, vibrators etc. The operation of this equipment will
generate noise ranging between 85-90 dB (A) near the source. These noise levels will
be generated within the plant boundary and will be temporary in nature.
Noise Control Measures
Equipment will be maintained appropriately to keep the noise level within 85 dB(A).
Wherever possible, equipment will be provided with silencers and mufflers. Acoustic
enclosures will be provided to stationary machines like DG sets. High noise generating
construction activities will be restricted to day time only. Further, workers working in
high noise areas will be provided with necessary protective devices e.g. ear plug, ear-
muffs etc.
Water Environment
The water requirement during construction for the proposed plant will be met from
GWIL. Water will be required for construction activities, sprinkling on pavements for
dust suppression and domestic & non domestic usages. Runoffs from the construction
yards and worker’s camps during monsoon may affect the quality of water bodies in the
project area. Impact on water quality during the construction phase may arise due to non-
point discharges of sewage from the workers camp stationed at the project site.

Impacts & MitigationMeasures
Pollution and Ecology Control Services(PECS), Nagpur P a g e | 71
Mitigation Measures
The earth work (cutting and filling) will be avoided during rainy season and will
be completed during the winter and summer seasons only.
Stone pitching on the slopes and construction of concrete drains for storm water
to minimize soil erosion in the area will be undertaken.
The development of green belt will be undertaken during the monsoon season.
Soil binding and fast growing vegetation will be grown within the plant
premises to arrest the soil erosion.
Septic tanks followed by soak pit will be provided.
The overall impact on water environment during construction phase of the proposed plant
will be temporary and insignificant.
Solid Waste
During installation of new structure there may be some accumulation of scrap, boulders
and solid waste at site which will be removed by building material suppliers. Additional
work force deployed at site will generate garbage. Unless suitable disposal methods are
adopted, the accumulated garbage can have adverse primary impact on land environment
through fouls smell. This may lead to secondary impacts of health hazard to the workers.
The impact due to this will be overcome by good housekeeping. Top soil removed during
construction will be utilized for the green belt development.
Socio Economic Environment
The impact of the proposed plant on socio economic conditions of the local people of the
study area are expected to be positive during construction phase.
The local population will have employment opportunities due to the proposed
project. The local people will be preferred during the construction phase. This will
help in up-liftment of local people in terms of economy and social welfare

The pollutants released into the atmosphere will disperse in the down wind direction and
finally reach the ground at farther distance from the source. The concentration of ground
level concentrations mainly depends upon the strength of the emission source and
micrometeorology of the study area.
In order to estimate the ground level concentrations due to the emission from the
proposed project, EPA approved Industrial Source Complex AERMOD View Model has
been employed.
The mathematical model used for predictions on air quality impact in the present study is
ISC-AERMOD View. It is the next generation air dispersion model, which incorporates
planetary boundary layer concepts.

CHAPTER 5:
ANALYSIS OF ALTERNATIVES (TECHNOLOGY & SITE)
5.1 ALTERNATE TECHNOLOGY
The manufacturing of M.S. Billets/Ingots using Induction Furnace technology is a
globally proven technology adopted by all for medium scale industry. It is latest
technology with advantage of low capital cost, low power consumption; low slag
generation provided compared with other technology. Its installation is relatively easier
and its operation is simpler. Among other advantages, there is very little heat loss due to
rotation from the furnace as the bath is constantly covered and there is practically no
noise attending its operation. The molten metal in an induction furnace is circulated
automatically by electro-magnetic action so that when alloy additions are made, a
homogeneous product is ensured in minimum time. The major advantages of Induction
Furnace over the other furnace system are as follows:
• Optimized Consistency: Induction heating eliminates the inconsistencies and
quality issues associated with open flame, torch heating and other methods.
• Maximized Productivity: Production rates can be maximized because induction
works so quickly; heat is developed directly and instantly (>20002 F. in < 1
second) inside the part. Startup is virtually instantaneous; no warm up or cool
down cycle is required.
• Environmentally Sound: Induction heating systems do not burn traditional fossil
fuels; induction is a clean, non-polluting process which will help protect the
environment. An induction system improves working conditions for your
employees by eliminating smoke, Waste heat, noxious emissions and loud noise.
Heating is safe and efficient with no open flame to endanger the operator or
obscure the process. Non-conductive materials are not affected and can be located
in close proximity to the heating zone without damage.
• Energy Conservation: Overall energy efficiency in induction melting ranges
from 55 to 75 percent, and is significantly better than combustion processes.

• Higher Yield: The absence of combustion sources reduces oxidation losses that
can be significant in production economics.
• Faster Startup: Full power from the power supply is available, instantaneously,
thus reducing the time to reach working temperature. Cold charge-to-tap times of
one to two hours are common.
• Flexibility: No molten metal is necessary to start medium frequency coreless
induction melting equipment. This facilitates repeated cold starting and frequent
alloy changes

e) ENVIRONMENTAL MONITORING
Necessary provisions for routine monitoring of stack emissions, ambient air quality, noise
level, water quality as required by the regulations will also be provided.
f) SOLID WASTE MANAGEMENT/DISPOSAL
The solid waste generated will be in the form of slag. The total quantity of proposed slag
generation will be approx. 11,100 TPA. Slag crushers will be installed to recover iron
particles to be reused in Induction Furnace. Slag generated from Induction Furnace will
be used for hardening of working area, internal road, brick manufacturers and concreting.
The used machine oil of 0.1 TPA will be sell to registered oil vendors only.
g) GREENBELT DEVELOPMENT
Development of a greenbelt around the proposed facility mitigates to a certain extent the
potential negative impact on the environment due to dust, air emissions, fugitive emission
and noise. A green cover itself acts as containment for dust. Presence of a green belt, will
lead to micro-climate and soil quality balancing, by retaining soil moisture, recharge of
ground water as well as self-control of micro- climate of that area. It also improves the
aesthetic value of the area, later on it becomes the natural habitat of various bird species.
Development of a green belt around the proposed project site will also help to contain
noise generated during construction and operational phases.
In view of this, plantation and green belt development will be taken care in the plant and
the space reserved for plantation will be more than 33% of the total plant area. Plantation
will be made accordingly. For development of green belt Rs50,000 per Ha will be
allotted. The selection of plant species will be based on the local soil conditions. Post
plantation care like watering and protection from grazing will be done. The plant species
recommended for strengthening the existing plantation are presented in Table. However
