IDENTIFICATION, PREDICTION AND EVALUATION OF IMPACTS:

Environmental impact can be defined as any alteration of environmental conditions, adverse

or beneficial, caused or induced by the action or set of actions under consideration.

Various operations involved in the proposed project have been studied in details to identify,

predict and evaluate impacts on various environmental components. The identified impacts

were quantified using mathematical models to a possible extent so as to estimate the future

environmental scenario.

exhaust. • Speed restriction of all vehicles.

• Vehicles will be checked for PUC certification.

The fugitive dust emission

sources are:

• 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 with tarpaulin

& 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.

POST CONSTRUCTION PHASE:

DG sets: Stack height calculation

There will be no additional DG set required for the project. Power back up to the common

areas and essential services will be arranged through DG set of capacity 320 kVA –3 no. The

details are tabulated as under:

1. 320 kVA - 3 nos. 66.6 l/hr/per DG 800-850 kg/cm3 0.05% 42.50 m

Calculation of stack height:

The stack height of proposed DG set is calculated as under:

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

= 0.2 x (√320)

= 0.2 x 17.88

= 3.57 m

Say = 3.5 m

However, a safe stack height of 42.50 m.

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).

Presentation of Results

In the present case, model simulations have been carried out for the study period. The Ground

level concentrations are computed for 24-hr average. Maximum Ground level concentrations

of NOx and CO for study period were 4.2 µg/m3 and 3.2 µg/m3 respectively. The obtained

GLC’s are well within the stipulated CPCB standards. The incremental ground level

concentrations for NOx and CO are given in Table-2 (a).

CONSTRUCTION PHASE:

During construction phase following will be the tentative sources of noise:

Name of Source Noise level at 16 m from

source {dB (A)}

Noise level at 1 m from source

{dB (A)}

Back hoe/Loader 81 105

Dump truck 83 107

Generator Not considered 75 (as prescribed by CPCB)

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 68.9 56 69.1

All values are in dB(A)

From the above, it is clearly seen that there will be no significant impact on the

surrounding community due to noise from the proposed activity.

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

maintenance of machines, providing PPE’s to workers, etc., the impact on noise levels will be

minimal.

CONSTRUCTION PHASE:

SOURCES MANAGEMENT

Major sources of • The construction area will be shielded with help of tarpaulin sheets.




noise pollution:

• Vehicular traffic

• Heavy moving

machinery

• Operation of

D.G. sets, etc.

• Complete construction work especially heavy earth work will be done during

day time.

• Traffic planning and management will be made adequate to ensure

uninterrupted traffic movement in the area so as to minimize the noise due to

congestion.

• The vehicles will be regularly maintained and optimum use of the same will

be made.

• Moving parts of the machines will be maintained properly so as to avoid

metal-to-metal impact noise.

• EPA/CPCB certified DG sets conforming to the standards for noise will be used.

• D.G. sets will be housed in an inbuilt acoustic enclosure, which will help to

contain the noise within the permissible standards.

• The driveways will have sufficient width so that there is no congestion of

vehicles during peak hours which will lead to increase in the noise levels.

• Adequate parking including provisions of visitors parking.

• Entry & exits will be manned with trained & efficient security to ensure smooth

flow of vehicles.

• There will be less starting and stopping and the vehicles will be speed restricted

to ensure the noise remains within the permissible limits.

• The area will cover 22.21% (7,978.00) area under landscape, which will help to

absorb noise.

ENERGY:

• Taking advantage of day lighting wherever possible to reduce the need for electric

lights.

• About 25.0 KL of hot-water requirement will be met through solar hot-water

generators (32 nos.).

• Power factor will be maintained around unity. All capacitors will be provided with

Harmonic Filters to avoid distortion in Voltage.
