This chapter gives an idea and description of environmental status of the study area with
reference to the prominent environmental attributes. The general studya area covers 10
km. radius of the plant. Baseline data has been collected from March 2013 to May 2013.
The impact identification always commences with the collection of baseline data such as
ambient air quality, ground water quality, surface water quality, noise levels, land
environment, land use pattern, flora & fauna and socio economic aspects within the study
zone of 10 km. radius.
3.1. AIR ENVIRONMENT
3.1.1. METEOROLOGY
Meteorology of the study area plays an important role in the air pollution studies. The
prevailing micro meteorological conditions at the mine area will regulate the dispersion
and dilution of air pollutants in the atmosphere. The predominant wind directions and the
wind speed will decide the direction and distance of the most affected zone from the
proposed activity. The meteorological data collected during the monitoring period is very
useful in interpretation of baseline as input for dispersion models for predicting the
Ground Level Concentrations (GLC).
3.1.2. METEOROLOGICAL DATA RECORDED AT SITE
A Temporary Weather Monitoring Station has been installed at the site and temperature,
relative humidity, wind direction, wind speed, and rainfall were recorded for one season.

3.2 NOISE ENVIRONMENT
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 being to a complex sound
made up various frequencies at different loudness levels. The most common and heavily
favoured of those scales is the A weighted decibel (dBA). This is more suitable for audible
range of 20 to 20,000 Hertz. The scale has been designed to weigh various components of
noise according to the response of a human ear.
HANUMAN MINERALS
Silica Sand Mine (Quartzite)
CHAPTER - III
REIA report

The impact of noise sources on surrounding community depends on:
Characteristics of noise sources (instantaneous, intermittent or continuous in nature). It is
well known that steady noise not as annoying as one that is continuously varying in
loudness.
The time, at which noise occurs, for example loud noise levels at night in residential
areas are not acceptable because of sleep disturbance.
The location of the noise source, with respect to noise sensitive area, which determines
the loudness and period of noise exposure.
The environmental impact of noise can have several effects varying from Noise Induced
Hearing Loss (NIHL) to annoyance depending on loudness of Noise levels.
The environmental impact assessment of noise from mines can be carried out by taking into
consideration of various factors: potential damage to hearing, potential physiological
responses and annoyance and general community responses.
The main objective of noise level monitoring is to assess the background noise levels in
different zones viz., industrial, commercial, residential and silence zones within the study
area. The basic studies conducted were
a. Assessment of background noise levels.
b. Identification and monitoring the major noise generating sources in the study area.
c. Impact of noise on general population in the study zone of 10 km. radius.
3.2.1.RECONNAISSANCE
Noise levels were measured at different locations within 10 Km. radius of the proposed
project such as villages, bus stands etc.
3.2.1.1 BACKGROUND NOISE
Baseline noise data has been measured at different locations using A-weighted sound
pressure level meter. The equivalent day-night noise levels in the study zone are ranging
from 43.65 dBA to 52.35 dBA.

3.2.1.2 SOURCES OF NOISE
Typical considerations in environmental noise assessment can be divided into two
categories; one is related to noise sources and the other related to potential receiver.
Two quantities are needed to describe completely the strength of the source. They are sound
Power level and directivity. Sound Power levels measures the total sound Power radiated
by the source in all directions where as directivity is a measure of difference in radiation
with direction. This concept of sound Power level and directivity index makes it possible to
calculate the sound pressure level created by the source.
3.2.2 COMMUNITY NOISE
The ambient noise level is characterized by significant variations above a base or a residual
noise level. The residual noise level is that level below which the ambient noise does not
seem to drop during a given time interval and is generally caused by the unidentified
distant sources. It differs in rural and urban areas. At night, its level is low due to lesser
elements of noise. The annoyance that people experience depends upon the number of noise
elements that produce noise concurrently at a given time that occur during a time interval.
The noise rating developed by EPA for specification of community noise from all sources is
the day night sound level, Ldn. It is similar to a 24 hour equivalent sound level except that
during the night period, which extends from 09.00 p.m. to 6.00 a.m. A 10 dBA weighing
penalty is added to the account for the fact that noise at night when people are trying to
sleep is judged more annoying than the same noise during the day time.
The Ldn for a given location in a community is calculated from an hourly equivalent sound
The rainwater shall be coursed into the mine by developing suitable drainage system
and accumulated in the mined out pit. The water collected in the pit, after settling of
the suspensions, shall be used for afforestation & mine spraying. Further, as the water
collected in the sump is not likely to have any dissolved harmful elements.
As a precautionary measures before onset of monsoon, garland drain will be
maintained to divert water from outside the mining area. The rainwater thus diverted
is coursed to natural nallahs or collected in the sumps. This helps to control the
inflow of water from the virgin areas into the mine workings. The floors of different
benches are gently sloped so that working remain water free.
At the end the mine operation the proponent has proposed to convert few of the mining
pits into artificial ponds to store the rainwater, which could be used as a reservoir in the
locality which will in turn help in recharging the groundwater table. Rainwater harvesting
will be taken up after consulting the concerned officials about the feasibility of such a setup,
so that water stored can be used for water sprinkling and afforestation purposes thereby

CHAPTER – XI SUMMARY
1) Source of dust emissions will be due to mine operations and transportation of Silica Sand
(Quartzite) by vehicles on access roads and haul roads. The following measures will be
taken to control the dust emissions.
Applying water for dust suppression on mine haul roads.
Regular Compaction & grading of haul roads and service roads to clear accumulation of
loose material.
Compaction & gradation on both sides of Haul Roads.
Controlling speed of dumpers / trucks.
Avoid overloading of dumpers and consequent spillage on the roads.
2) There will be no waste water generation due to mining activity. Only waste water
generation will be sanitary waste water which will be treated in septic tank followed by
soak pit. Zero effluent discharge will be maintained. Hence there will not be any adverse
impact on water environment due to the mining of Silica Sand.
3) No overburden / Top soil will be generated due to the mining as the silica sand is exposed
to surface.
4) Greenbelt will be developed in and around the Mine Lease area.
