1. INTRODUCTION
One of the Medical and Educational Trust proposes to
expand its Institutional Buildings in Mevalurkuppam &
Chettipedu villages, Sriperumbudur Taluk, Kanchipuram
District in the state of Tamil Nadu. The project proponent
proposes to obtain Environmental Clearance for the land
area of 5, 03,914.56 Sqm (124.51 acres) and the built up
area of 2, 90,710.17 Sqm (Existing Buildings – 2, 48,516.13
Sqm & Proposed Buildings – 42,194.04 Sqm). The
proposed project falls under 8(b) category as per MoEF,
EIA Notification, and 14th September 2006. Hence it is
required to submit TOR and Rapid Environmental Impact
Assessment (REIA) study as per State Environmental
Impact Assessment Authority, Chennai.

The physical description of sound concerns its loudness as
a function of frequency. Noise in general is sound, which is
composed of many frequency components of various
loudness, distributed over the audible frequency range.
Various noise scales have been introduced to describe, in a
single number, the response of an average human to a
complex sound made up of various frequencies at different
loudness levels. The most common and universally
accepted scale is the A weighted Scale which is measured
as dB (A). This is more suitable for audible range of 20 to
20,000 Hz. The scale has been designed to weigh various
components of noise according to the response of a human
ear. The impact of noise sources on surrounding
community depends on:
Characteristics of noise sources (instantaneous,
intermittent or continuous in nature). It can be
observed that steady noise is not as annoying as one,
which is continuously varying in loudness;
The time of day at which noise occurs, for example
high noise levels at night in residential areas are not
acceptable because of sleep disturbance; and
The location of the noise source, with respect to
noise sensitive land use, which determines the
loudness and period of exposure.

As seen from the water quality result Table, Calcium and
Magnesium content varies between 79 to 21 mg/l and 52
to 12 mg/l respectively.
Total hardness and alkalinity expressed as CaCO3 ranges
between 340 to 150 mg/l and 186 to 152 mg/l
respectively. The study area is fast developing commercial

4. CONCLUSIONS
The proposed project is an Institutional building
construction project. During construction and operation
phases there may be minor environmental issues of air,
water and soil pollution.
During construction phase air pollution may be due to
dust, vehicular movements by transportation and material
handling, etc and during the operation phase emissions
may occur from the diesel generators.
Water Pollution is not much significant due to this
proposed project since proper waste water management is
proposed to be carried out.
Also, the noise generated during construction and
operation phase caused due to vehicular movements and
machineries will be minimized using proper adequate
preventive measures.
Further, the proposed project will include proper solid
waste management techniques which would prevent the
environment from any adverse effects caused due to solid
waste generated from the proposed project site.

The physical description of sound concerns its loudness as
a function of frequency. Noise in general is sound, which is
composed of many frequency components of various
loudness, distributed over the audible frequency range.
Various noise scales have been introduced to describe, in a
single number, the response of an average human to a
complex sound made up of various frequencies at different
loudness levels. The most common and universally
accepted scale is the A weighted Scale which is measured
as dB (A). This is more suitable for audible range of 20 to
20,000 Hz. The scale has been designed to weigh various
components of noise according to the response of a human
ear. The impact of noise sources on surrounding
community depends on:
Characteristics of noise sources (instantaneous,
intermittent or continuous in nature). It can be
observed that steady noise is not as annoying as one,
which is continuously varying in loudness;
The time of day at which noise occurs, for example
high noise levels at night in residential areas are not
acceptable because of sleep disturbance; and
The location of the noise source, with respect to
noise sensitive land use, which determines the
loudness and period of exposure.

As seen from the water quality result Table, Calcium and
Magnesium content varies between 79 to 21 mg/l and 52
to 12 mg/l respectively.
Total hardness and alkalinity expressed as CaCO3 ranges
between 340 to 150 mg/l and 186 to 152 mg/l
respectively. The study area is fast developing commercial
and residential area the extraction of ground water is
envisaged in huge quantity, the proper rain water
harvesting and storm water drains has been designed in
the project site to increase the recharge potential of rain

4. CONCLUSIONS
The proposed project is an Institutional building
construction project. During construction and operation
phases there may be minor environmental issues of air,
water and soil pollution.
During construction phase air pollution may be due to
dust, vehicular movements by transportation and material
handling, etc and during the operation phase emissions
may occur from the diesel generators.
Water Pollution is not much significant due to this
proposed project since proper waste water management is
proposed to be carried out.
Also, the noise generated during construction and
operation phase caused due to vehicular movements and
machineries will be minimized using proper adequate
preventive measures.
Further, the proposed project will include proper solid
waste management techniques which would prevent the
environment from any adverse effects caused due to solid
waste generated from the proposed project site.
