The dust emission sources are:

• Excavation

• Haul road movements

• Construction

• Material Handling

• Finishing

• Water spraying to prevent dust pollution from different sources

of construction.

• All transportation vehicles will be suitably covered &

overloading of the vehicles will be avoided.

• Covering of the construction site on all four sides to a

considerable height to prevent dust emissions and other

pollutants to the surrounding environment.

• Ensuring vehicles stick to the access track to prevent mud and

dirt being deposited on roads.

2. DG sets:

The source of emission will be from a D.G. set of capacity of 320 kVA which will be used in

case of power cuts or failure.

The details are as under:



11

Calculation of stack height of D.G. sets

The stack height of DG set is calculated as under:

H = 0.2 (√capacity of the DG set in kVA)

= 0.2 x (√320)

= 0.2 x 17.89

= 3.58 m

However, a safe stack height of 31 m above the roof of DG house will be provided.

Impact on Air Quality

The impact on air quality is assessed based on emissions of the proposed DG set and vehicular

emissions. NOx and CO will be the important pollutants emitting from these sources. Prediction of

impacts on air environment has been carried out employing mathematical model based on a steady

state Gaussian plume dispersion model designed for multiple point sources for short term. In the

present case, AERMOD Version 7.1.0 dispersion model for different stability state Gaussian plume

dispersion, designed for multiple point and line sources for short term and developed by United States

Environmental Protection Agency [USEPA] has been used for simulations from point and line sources.

Model Input Data

For the modeling purpose, all pollutants as described above are considered. The details of stack

emissions and line emissions envisaged from the project are given in Table-1 (a) & (b).

CONSTRUCTION PHASE:

To understand the combined effect of these noise levels on the nearby community, Custic 3.2 (Lakes

Environmental – USEPA approved) scientific model has been used to estimate the noise levels at

different distances from the proposed project. All the major noise generating machineries like D.G.

Sets, Pumps, Trucks, vibrators, drilling machine, etc., are considered in this model. The noise level

at project boundary due to different sources is calculated based on the following formula:

Lp2 = Lp1 – 20 log (r2 / r1) – Ae1, 2

where, Lp1 and Lp2 are sound levels at points located at distance r1 / r2 from the source and Ae1,2 is

the excess attenuation due to environmental conditions. The resultant noise level is obtained by

adding existing maximum levels to that of predicted level.

The predicted noise levels based on the above analysis at the project boundary considering that there

is no attenuation on account of barriers, will be as follows:

LOCATION MAX.EXISTING MAX. PREDICTED RESULTANT MAX

Project Site 50.2 59 59.5

All values are in dB(A)

Further due to natural attenuation effects, by proper green belt development, design / maintenance of

machines, provision of PPE’s for the workers, etc., the impact on noise levels will be minimal.

help to absorb noise.

ELECTRICAL HAZARDS SAFETY MEASURE PLAN

DEFINITION

Electrical Hazard –

A dangerous condition such that contact or equipment failure can result in Electric shock, arc-flash

burn, thermal burn, or blast. Electrical hazard includes ‘dangerous’ meaning ‘able or likely to

inflict injury’; there are high voltage, low current sources that are not intrinsically dangerous, and

there are low-voltage, high-current sources that are not ‘safe’. A ‘harmless’ static electricity shock

could cause sufficient startle reaction to make a worker fall off a ladder. A hazard analysis is

necessary to identify electrical hazards and determine the degree of risk. We are considering

different types of measures for preventing electrical hazards which are as follows:

Safe Electrical Installation

� Installation of new electrical systems to a suitable IS standard. Requirements for electrical

installations, and then maintain them in a safe condition;

� Provision of enough socket-outlets - overloading socket-outlets by using adaptors which can

cause fire.



27

Provision of safe and suitable equipment:

� Proper selection of equipments;

� There will be provision of an accessible and clearly identified switch near each fixed

machine to cut off power in an emergency;

� For portable equipment, there will be use of socket-outlets which are close by so that

equipment will be easily disconnected in an emergency;

� The ends of flexible cables will always have the outer sheath of the cable firmly clamped to

stop the wires (particularly the earth) pulling out of the terminals;

� Damaged sections of cable will be replaced completely;

� There will be use of proper connectors or cable couplers to join lengths of cable

� There will be proper protection of light bulbs and other equipment which could easily be

damaged in use. And also creates risk of electric shock if they are broken;

� Electrical equipment used in flammable/explosive atmospheres will be designed to stop it

from causing ignition.

Reduction of Voltage:-

One of the best ways of reducing the risk of injury when using electrical equipment is to limit the

supply voltage to the lowest needed to get the job done, such as:

Temporary lighting can be run at lower voltages, e.g. 12, 25, 50 or 110 volts;

� Where electrically powered tools are used, battery operated will be safest;

� Portable tools are readily available which are designed to be run from a 110 volts centre-

tapped-to-earth supply.

Provision of safety device

If equipment will be operated at 230 volts or on higher, then the provision of an RCD (residual

current device) will be provided as an additional safety. An RCD is a device which detects some,

but not all, faults in the electrical system and rapidly switches off the supply. RCD will be built

into the main switchboard or the socket-outlet, as this means that the supply cables will be

permanently protected. Additionally a plug incorporating an RCD, or a plug-in RCD adaptor, will

also be provided for an additional safety. RCDs for protecting people have a rated tripping current

(sensitivity) of not more than 30 milliamps (MA).

� An RCD is a valuable safety device, never bypass it;



28

� If the RCD trips, it is a sign there is a fault.

� The RCD will have a test button to check that its mechanism is free and functioning.

Work safely

We will make sure that people who are working with electricity are competent to do the job. Even

simple tasks such as wiring a plug can lead to danger – we will ensure that people know what they

are doing before they start.

We must not allow work on or near exposed live parts of equipment unless it is absolutely

unavoidable and suitable precautions will be taken to prevent injury, both to the workers and to

anyone else who may be in the area.

Underground power cables

Always assume cables will be present when digging in the street, pavement or near buildings. The

usage will be up-to-date service plans, cable avoidance tools and safe digging practice to avoid

danger.

Overhead power lines

When working near overhead lines, it may be possible to have them switched off. So, we will keep

the safe working distance from the cables.

BASIC PRECAUTIONS:

There are various ways of protecting people from the hazards caused by electricity, including

insulation, guarding, grounding and electrical protective devices. We will significant reduce

electrical hazards by following some basic precautions.

Insulation

All electrical cords will have sufficient insulation to prevent direct contact with wires. All cords

will be checked before each use, since corrosive chemicals or solvent vapors may erode the

insulation. Damaged cords will be repaired or taken out of service immediately, especially in wet

environments such as cold rooms



29

Guarding

Live parts of electric equipment operating at 50 volts or more will be guarded against accidental

contact. Plexiglas shields may be used to protect against exposed live parts.

Grounding

Only equipment with three-prong plugs will be used. The third prong provides a

path to ground that helps prevent the buildup of voltages that may result in an

electrical shock or spark.

Circuit Protection Devices

Circuit protection devices will be designed to automatically limit or shut off the

flow of electricity in the event of a ground-fault, overload, or short circuit in the

wiring system. Fuses, circuit breakers, and ground-fault circuit interrupters are

three well-known examples of such devices.

Fuses and circuit breakers prevent over-heating of wires and components that might otherwise

create hazards for operators. They disconnect the circuit when it becomes overloaded. The ground-

fault circuit interrupter or GFCI, will be used to shutoff electric power if a ground fault is detected.

The GFCI will be particularly used near sinks and wet locations. Since GFCIs will cause

equipment to shutdown unexpectedly, they may not be appropriate for certain apparatus. Portable

GFCI adapters (available in most safety supply catalogs) may be used with a non-GFCI outlet.

Safe Work Practices

The following practices will be used to reduce the risk of injury or fire when working with

electrical equipment:

� Avoid contact with energized electrical circuits.

� Disconnect the power source before servicing or repairing electrical equipment.

� When it is necessary to handle equipment that is plugged in, be sure hands are dry and, when

possible, wear nonconductive gloves and shoes with insulated soles.

� If water or a chemical is spilled onto equipment, shut off power at the main switch or circuit

breaker and unplug the equipment.



30

� If an individual comes in contact with a live electrical conductor, do not touch the

equipment, cord or person. Disconnect the power source from the circuit breaker or pull out

the plug using a leather belt.

High Voltage or Current

Repairs of high voltage or high current equipment will be performed by trained electricians.

Individuals who are experienced in such tasks and would like to perform such work on their own

equipment must first receive specialized electrical safety related work practices training by EHS

staff.

Benefits from Plantation:

Maintaining vegetative cover will help in

o Reducing heat island effect

o Reducing flooding risk by increasing groundwater recharge

o Reducing erosion and polluting surface water bodies

Apart from this, maintaining tree cover will help in improving air quality by

o Reducing pollution

o Reducing dust

o Increasing oxygen content

Keeping native species can lead to cost savings through

o Reduced maintenance due to greater adaptability

o Reduced water requirement

Native plantation will help in

o Attracting native fauna and migratory species creating ‘urban niches’

o Increasing the aesthetic quality of the development without extensive maintenance

Conclusion:

Construction projects, whether commercial, residential, public sector or infrastructure projects all

have the potential to damage natural habitats, threatening wildlife and plant species. The

construction industry therefore has an important role to play protecting sensitive sites and

minimizing damage to ecology.

Creating new habitat is generally of less ecological value than protecting and enhancing existing

habitat. However, in this project, local/common plant species will be selected that can provide

important habitat for wildlife, and other appropriate features and creating conditions for habitat to

develop naturally.

Looking towards the existing biodiversity in the study area, no any endangered, threatened or

endemic species exists in the study area, so insignificant impact is visualized on the flora and fauna

of the project site.
