Silence zone is defined as areas upto 100 meters around such premises
as hospitals, educational institutions and courts. The silence zones are to
be declared by the Competent Authority
Mixed categories of areas should be declared as ''one of the four above
mentioned categories by the Competent Authority and the
corresponding standard shall apply
The observed data in project site and buffer zone shows that the Ambient noise level
range between min 44.8 dB (A) to max 68.4 (A) & Avg Leq 60.14 The quarry site and buffer
zone noise level values are well within the Ambient Noise Standards.
NOISE POLLUTION CONTROL
In an operational beneficiation plant major noise sources are operation of
machineries and equipment, operations. Noise generation may be for an instant,
intermittent or continuous periods, with low to high decibels.
As there are no villages within 1.0 km range, noise level will be insignificant as the
operations are of intermittent nature. Although the ambient noise level monitoring carried
out in and around the proposed plant shows that ambient noise levels are well within the
stipulated limits of CPCB.
Periodic inspection and checks of the risk prone areas and equipment shall be
conducted towards noise control.
Acoustic enclosures, hoods, laggings and screens shall be provided in noise
generating areas to the extent possible so that the sound pressure levels in working
areas are restricted below 85 dB (A) for 8 hours duty. This shall be regulated before
engaging the equipment or purchase of the same.
Provisions of rotation of workers to minimize exposure time as well as provision of
earmuffs to workers exposed to high noise areas are also envisaged. In addition to it,
green belt development shall be undertaken around the lease area to minimize
propagation of noise.
Regular monitoring of noise pressure level shall be done inside and outside the
quarry area.
The equipments and machines shall be maintained properly. Particular attention
should be given to the silencers and mufflers. Ear muffs or other protective devices
should be provided to the staff working in high noise prone areas.
Sharp drill pits shall be used to reduce the noise levels.
The rotating equipment shall be selected for lower operating speeds and will be
statically and dynamically balanced. The equipment shall be provided with silencers
wherever required, and shall be designed to operate with a total noise level of not

Health Administration (OSHA) Standards.
5.6 OCCUPATIONAL HEALTH & SAFETY MEASURE
All the above precautions would be adopted to prevent dust generation at site and
to be dispersed in the outside environment. However, for the safety of workers at
site, engaged at strategic locations/dust generation points like loading and
unloading points, dust masks would be provided. Dust masks would prevent
inhalation of RPM thereby reducing the risk of lung diseases and other respiratory
diseases. All employees shall be medically examined as per the mines Act
1952 and shall undergo Spirometry, Pulseoxymetry, and lungs function test etc.
The statutory norms shall be followed during the course of quarrying to ensure the
proper health and safety of workers. Apart from this there is no other factor
envisaged during the quarrying operations.
The health status of workers in the quarry shall be regularly monitored under an
occupational surveillance programme. Under this programme, all the employees’
shall be subjected to a detailed medical examination at the time of employment.
The medical histories of all the employees shall be maintained in a standard format.
Thereafter, the employees shall undergo medical examination on annual bases.
The examinations are proposed to be conducted in specialized area are given in the

The only source of water pollution from the Quarry is wash – off from the active
Quarrying area. The wash off would contain heavy colloidal suspension in the form of
Turbidity. The following mitigative measures shall be adopted to prevent wash off of
Quarry silt and uncontrolled runoff water during monsoon.
From the natural slopes the rainwater drains into the stream. The ground water
table is +40m below the surface. The proposed quarrying operations are much above the
ground water table. Therefore, these quarrying operations on hill top may not have any
adverse impact on either the yield or movement of ground water. The following control
measures shall be undertaken.
• To avoid soil erosion, rain water entering into the Quarry pit, carryover of the material
with rain water, suitable garland drains all along the active Quarry area shall be
provided.
• Plantation and fast growing deep rooted plant species.
• Providing sufficient gully checks & check dams to check any silt flowing along with the
surface run-off in the valleys.
• For arresting the solids escaping along with these run-offs in small streams, small
check dam shall be constructed all along the small streams before they join any surface
water bodies.
5.8 Soil Data:
The normal mineral composition of quarry is altered by alteration in soil condition.
Soil could well represent the topsoil cover, which is rich in nutrient content. Three
locations were selected as below for analyzing the soil quality status in the study. The

6.0 LAND ENVIRONMENT
6.1 CORE ZONE
The core zone completely falls in Govt. Revenue land on hill top and slopes. Most of
the area covered with rock formations over which some vegetation exists. The core zone is
partly disturbed to a very small extent due to Quarrying, which are worked earlier. The
ultimate land use plan is given in the Table No.2.

6.2 HANDLING OF WASTE AND SUB-GRADE MINERAL
No waste is expected to be generated during this plan period.
6.3 PROPOSED MITIGATIVE MEASURE.
� Green belt development around the foot of the hillock and near to the Quarry and
haulage roads shall be taken up simultaneously as this helps in afforestation.
� Use of good root bearing and hardy species like Honge, Neem etc., shall be planted.
6.4 RECLAMATION OF LAND
The mined out quarry pit shall be converted into rain water pond to recharge the
ground water. The rain water stored in the pit can also be utilized the nearby farmers for
cultivation.
6.5 PLANTATION PROGRAMME
Under plantation programme, it is suggested to develop 180 plants per annum
around foot of the hillock area & also along the road. The implementation of the
development of green belt around the hillock will be of paramount importance as it will not
only add up as an aesthetic feature, but also act as a pollution sink.
The species to be grown in the areas should be dust tolerant and fast growing
species so that a permanent green belt is created.
Apart from the green belts and aesthetic plantation, other massive plantation
efforts shall be decided and executed with the assistance and co-operation of the local
forest department to benefit the community and to reduce the effects of fugitive emissions
and noise pollution.

6.6 HUMAN SETTLEMENTS
There is no human settlement in the core zone. However there twelve villages in
buffer zone area of 5 kms radius.
DEMOGRAPHIC DETAILS:
As per 2011 census, the study area consisted of 23895 persons inhabited in 12
villages. The statistics regarding the list of villages, number of households and human
population is given in Table No.3.

6.7 SOCIO-ECONOMIC BENEFITS
Spurt in industrialization and Quarrying activities have invariably brought a drastic
change in the environment including the society connected with region. Mostly remote
areas tucked away from urbanization and influence of modern civilization fall within the
limits of mine development. A natural corollary to this the socio economic aspects of the
Building Stone Quarry Project report
M/s. GLOBAL Environment & Mining Services ..17
local inhabitants who have dwelling this region for generations, get suddenly and probably
a radical change, consequent to their abrupt exposure to the mining activities.
The impact of this mining project will be positive. The subject-mining project
provides employment for about 30 persons and also creates in the service sector for an
equivalent number of persons will be indirectly employed in the other allied activities.
Thus a population of about 120 persons can sustain their lively hood on this project. An
equal number of persons shall be sustain due to allied activities of quarry. Majority of the
work force shall be local people coming from and within the district.
The local people will get employment opportunities, better medical and
educational facilities etc., mainly due to the mining operation from this project. In addition
to this the literacy rate and better living standards shall increase due to the enhanced
earning capacity of villagers. This area will also have better Medical, Educational,
Transportation and communication facilities, which are also directly, linked with the
establishment of the mining project.
In the buffer zone villages, this project will be one of the major economic activities
resulting in generation of revenues to the state and central governments, by way of
royalties, taxes, central excise etc., and the living condition of the persons shall improve,
thus contributing to the overall up gradation of living standards. There would tremendous
earning of foreign exchange due to export of value added products instead of raw material
alone from this region.
The socio-economic parameters of the area undergo change due to:
� Changes in the employment pattern of the area.
� Changes in the pattern of facilities available, both in respect of the infrastructure
facilities as well as other services.
� Improvements in money supply in the area through better earning capacity of
population.
It proposes to taken up the following CSR activities listed below during the
Quarrying activities.
• To arrange study tour to primary and high school children.
• Assistance to Educational institutions located in the Taluk by way of providing
“Teaching aids, Books & Periodicals”.
• Scholarships for the best outstanding students.
• Health care camps arrangements and distribution of medicines freely. organising
occupational health camps through trained doctors.
• Employment oriented training to youth.

• Providing sanitation/sewage facilities to villages. etc. and educating on health of
hygiene matters.
• Providing solar lights to villages and schools, as there is scarcity of electricity.
• And any other requirements of the people in the surrounding area found to be essential
when communicating with them.
IMPLEMENTATION OF EMP & MONITORING PROGRAMME:
The environment management plan is detailed on the basis of impact assessment.
Control and mitigation measures for the adverse impacts envisaged. As the major
environmental attributes have been confined to the project area alone, implementations of
the proposed control measures and monitoring thereof will be undertaken on the regional
basis. The Lessee will ensure the implementation of the measures within the Quarry area
and carryout efficient monitoring.
In order to implement the measures suggested for mitigating the adverse impacts on
the environment, it is suggested to monitor the environmental parameters regularly.

6.11 BUDGET PROVISION FOR EMP
It is necessary to include the environmental cost as a part of the budgetary cost
component.
It is proposed to take up protective measures like construction of check dams
across the nallah. The haul roads both within the lease and outside the mining lease
including roads leading to the crushing plant are being watered and good drainage system
would be maintained. The project authorities propose to undertake the following
environmental works to achieve the environmental quality as desired.
The Lessee for execution of Environment Management Plan has made adequate
budgetary provision. Annual cost of monitoring and implementation of control measures is
