longitudes. The area is located at a distance of 03 km from Jarali village .
2.2 NEED FOR THE PROJECT
In order to meet the statutory requirements the lessee intends to obtain Environmental
Clearance from Statutory Authorities.
2.3 TOPOGRAPHY
The quarry lease applied area is located on a hill raised 34 M above ground level within
the quarry lease applied area with topo relief of 34 M. The lowest contour is 80 M and
highest contour is 114 M.
2.4 GEOLOGY
2.4.1 Regional Geology
The rock formation belong to eastern ghat mobile belt of Archaean Age. The mobile belt
is divided into three longitudinal zones viz., western charnockite zone (WCZ), the central
khondalite zone (CKZ) and the eastern migmatite zone (EMZ). The EMZ is well
developed in the northern parts of the belt around vishakapatnam, vizianagaram,
snicakulam and partly in the Krishna Districts. A broad distribution of types of rocks is
Srikakulam district are Granite Gneiss, Khondalites, Charnockites, Leptynites,
Rajmundry Sand Stone, Alluvium Deposits and quartzites at certain places.

The eastern part of the belt plain country with isolated hillocks are rises gently as
continuous hill range towards west presenting a rugged topography with lush green
vegetation. The area is drained by two prominent rivers originating from Orissa, namely
Nagavali and Vamsadhara passing almost parallel to one another at a distance of 8 km to
15 km apart through the district and joins the Bay of Bangal. The Srikakulam –
Viziangaram – Vishakapatnam area exposes mainly khondalite – Charnockite suite of
rocks forming a part of the EGMG which include Charnockite, Khondalite – Charnockite
to – pyroxene granulite, migmatite Leptynite and intrusive porphyroblastic charnockite
and granite. Out of these migmatite charnockite and leptynite are extensively quarried as
dimensional stone granite and traded as Srikakulam Blue.
The Colour granite rocks are termed Srikakulam Blue due to the present of Bluish
opalescent quartz and bluish grey feldspar – Actually these are migmatite and Migmatite
Charnockites.
Local Geology:
The rock is bluish grey in colour, medium to coarse grained, hard, compact, massive and
faoliated. The rock occurs on the sloping hillock with large boulder outcrops concealed
and embedded in soil. It contains quartz – feldspathic minerals with subordinate amounts
of garnet, pyroxenes, biotite and Fe-oxides, Feldspar shows effect of Kaolinasation. The
Magnetite is oxidized at places. Garnet and hydpresthene show porphyroblastic growth.
The rock shows few penetrative cracks and hairlines fractures. The generalized
lithological succession of the area is

The alternative arrangement of felsic & mafic minerals of the rock mass gives decorative
pattern with bluish grey background. Green and Brown. The other mineral assemblages
are Silliminite, Garnet and Quartz.
Details of prospecting carried out:
Present status of quarry lease: It is a fresh quarry lease. No exploration is carried out
in the quarry lease applied area. The colour Granite is well exposed to above surface in
this area. The deposit is exposed over a height of 34 meters with in the lease applied area
Keeping in view of the geological factors, it is field that no further exploration is
required. The overburden from the quarry is very limited. The top weathered portion is
not saleable as it is.
2.5 GEOLOGICAL RESERVES
The study of exposures in the quarry facilitated to access the shape and size of the
deposit. It is a hill deposit rising 75 M above ground level within the quarry lease applied
area. The lowest contour is 80 M and highest contour is 114 M.
Method of Estimation of Reserves:
The cross sections were drawn perpendicular to the strike direction, the cross sectional
area of the individual sections are calculated to arrive at sectional area, the area thus
arrived in multiplied by the sectional influence of 80 M to arrive the volume of rock
mass. Based on the physical appearance of the deposit it is assumed that recovery factor
of 20% is anticipated.
5 Sections A-A’ and E-E’ were drawn in South to North direction at equal interval of 80
mts (Approved mining plan Plate-III).
Based on the available explored deposit in the quarry lease applied area and parameters
considered to assess reserves, it has attempted to allocate the colour granite reserves
under UNFC code.

cutting will be deployed based on the favourable conditions. The development of benches
in the sheet rock will be maintained @ 600
safety slopes.
The separation of blocks from the mother rock will be carried out by drilling and
chiseling with hammers with small pressure after wire saw operations, drilling and
dousing with excavators will be done by through poclain teeth or with bucket separating
from the mother rock.
The second splitting, dressing of blocks will be done manually or poclain bucket by tam
rock machine with drilling and splitting.
Therefore, quarrying operations are to be carried out in this area in 2 stages, after
dressing the blocks buyer will mark their company code on the block and placed in the
stock yard.
Stage- 1 : The removal of weathered and under sized boulders will be cleared in the
quarry lease applied area for the next five years by using excavator.
The sheet that is exposed will be subjected to drilling, with compressors and tam rocks,
chiseling with hammers applying pressure by poclain teeth and splitting from mother
rock.
Rock splitting / Wedging : Thus 20’ x 20’ to 40’ x 20’ to 40’ mass will be separated
from mother rock by drilling the slotter holes on both sides of the mass and a top holes
intersecting these two holes and wiresaw rope is passed through and cutting is done
horizontally and vertically and by this there will be mass opening on all the sides from
the mother mass.
For splitting the mass from mother rock the line drilling and wedging method is in use;
with jack hammer and this waste will be dumped at dumping yard using tipper and
excavators.
Stage-2: After removal of weathered and under sized boulders.
The large boulders will be subjected to splitting into required sizes of blocks
by using Jack Hammers by drilling series of deep holes at right angles at
regular intervals, later by inserting feather and wedges in these holes and
hammering with sledge hammer will release the blocks.

The boulders will be splitted to the required sizes with drilling and if required
by using chemical compound at the source only. The boulders separated will
be brought to the dressing yard for dressing.
If the boulders, which fit into the required market grade size will be
transformed into cuboids.
Secondary Splitting : After separation from the mother rock, it is properly checked by
washing with water to identify defects and cracks. Based on this observation, the size is
decided and the blocks are marked and separated by drilling and wedging.
The separated pieces will be examined for defects and lines, then the block or blocks are
marked in clear area and holes are drilled along the line of marking , with the help of
feathers and wedges the waste portions are separated forming a rectangular blocks. Any
bulges will be removed by drilling and wedging making it perfect blocks. A perfect block
is that all the sides shall make with each other 900.
Dressing : Dressing of dimensional rough blocks for export: Dressing is final phase of
mining operation, wherein the secondary rough blocks are squared into regular perfect
rectangular sizes, thereby avoiding uneven bulge or cavities and other defects.
Jackhammers with compressor, feather end wedges and sledgehammers are equipments
generally used for dressing the block.
Dressing of rough blocks for domestic processing plant: Dressing by means of squaring
and splitting will be done for rough blocks of the size varying between 120 x 90 x 80 to
300 x 200 x190 M.
Description of granite processing plant: The lessee company does not possess processing
plant.
Beneficiation (If required) : Not applicable

3. EVALUATION OF IMPACTS
3.1 INTRODUCTION
Opencast mining activity causes some adverse impacts on the surround environment
unless proper environmental management plan is adopted. Selecting suitable sites for
mining and adopting the guidelines prescribed by the Ministry of Environment & Forests
(MoEF) and Indian Bureau of Mines (IBM), one can minimize the major possible
impacts.
In this chapter, an attempt has been made to quantify the possible environmental impacts
on various features such as air, water, noise, land, ecology and socio-economies. The
following aspects have been studied to identify the possible impacts while achieving the
total production of 17022 Cum/Year of Colour Granite.
The magnitude and significance of the environmental pollution caused by mining
depends on method of mining, scale and concentration of mining activity.
3.2 AIR ENVIRONMENT
The impacts on air environment from a mining activity depend on various factors like
production capacity, machinery involved, operations and maintenance of various
equipments and vehicle. Apart from these, there will be other activities associated viz
transportation of mineral and waste, stocking facilities and dump management within the
mine lease area that may contribute to pollution.
3.2.1 SOURCES OF DUST EMISSION
Mining is carried out by open cast semi mechanized method by using jack hammer
drilling & wire saw cutting and using low explosive blasting. Based on the various
operations involved in the production of minerals, the various emission sources has been
identified as given below.
EMP Report For Colour Granite Mine of 7.850 Ha, located in Jarali Village, Sarvakota Mandal, Srikakualm District, A.P.
Sri Choudhry Suresh
Global Enviro Labs, Hyderabad 15
a. Point soruces
b. Area sources.
c. Line sources.
Drilling operations of the mine are considered as point sources. Extraction of mineral
from mine, are considered as area sources. Transportation of material from mining
benches to various end points are considered as line sources. The impact of above sources
on air environment is discussed below:
a) Drilling & Blasting
Once the boulder is freed by removing the soil and waste rock surrounding it, a series of
holes are drilled by compressed air using Jack Hammer at a regular interval of 15-30 cms
depending on the size of the boulder, the depth of the hole depends on the height of the
boulder and the holes are drilled up to the bottom leaving about a foot at the base. The
holes have to be perfectly straight and vertical so that the vertical split is obtained. Line
drilling machine can be used to drill straight holes. Feather and wedges are inserted into
the holes and hammered continuously applying uniform pressure and the boulder splits
vertically. Similarly dressing is done and the boulder is given a rectangular shape. All the
defects are avoided during the dressing stage. Diamond wire saw may also be employed
to dislodge the block from the parent rock.
Drill hole pattern will be uniform single lined pattern, equidistance holes from 0.33 m to
0.75 m, 4.5 m in depth. Spacing depends upon the size of the boulder, in general it 15
cms from hole to hole for better splitting.
The concentrations due to low explosives blasting will be confined to a maximum
distance of 10 m from the area of blasting. These concentrations will not be emitted
continuously. However presence of personnel near the blasting site during blasting will
be totally avoided. So, the impact of blasting on the air environment will be minimal.
b) Extraction & Loading
Extraction & Loading will be done by a crane and excavator and these activities of mine
operation is contributing to the area source emission and the extent of influence of this
operation is about 100 m2.

Sri Choudhry Suresh
Global Enviro Labs, Hyderabad 16
c) Haulage &Transportation
In the operating mine, the dressed blocks from mine face to the consumers is transported
by hired trucks. The trucks will be well maintained so that exhaust smoke does not
contribute abnormal values of noxious gases and unburnt hydrocarbons. The other
sources of air pollution are due to the dust generated during the movement of tippers on
the haul road.
The above sources, which include drilling, low explosives blasting, excavation, haulage
for transport of blocks will contribute to dust pollution in the air.
3.2.2 ANTICIPATED IMPACTS
The impacts envisaged due to mining activity are evaluated based on various factors. The
emission inventory of the pollutants is as follows, the main air pollutant would be dust or
particulate matter generated by handling and transportation of colour granite. But the
impact of mining operations on air quality is minimum as mining involved method by
using jackhammer drilling & wire saw cutting & low explosive blasting and as the
production quantity is very less i.e. 68.08 Cum/Day only.
3.2.2.1 Dust Generation and Control
The air pollutant would be dust or particulate matter generated by handling and
transportation of granite blocks. The envisaged production of minerals is only 68.08
Cum/Day. The dust generated due to mining operations will be controlled by water
sprinkling through water tankers.
3.3 NOISE ENVIRONMENT
Noise will be produced at the mine is due to operations of machinery, drilling, blasting,
and movement of vehicles. The noise generated by the mining activity is dissipated
within a small zone around the mine. There is no major impact of the mining activity on
the vicinity however; pronounced effect of above noise levels will felt only near the
EMP Report For Colour Granite Mine of 7.850 Ha, located in Jarali Village, Sarvakota Mandal, Srikakualm District, A.P.
Sri Choudhry Suresh

active working area and on the personnel working in the vicinity. The impact of noise on
the villages is negligible as the villages are located far from the mine site.
3.4 WATER ENVIRONMENT
The Mining activity will be carried out on mound slope will not have any effect on the
ground water and the static water table in this area is below 55 m.
3.4.1 Impact on Surface Water
There are no major streams and rivers, which can get effected by the mining. Hence,
there will be no effect on the surface water.
During the present plan period quarrying will go to depth of 10 meters from the present
level of mining. During the monsoon period, the rainwater, if gets stagnated, will be
drained out. The benches will made with an inward slope to facilitate run off more faster
on to the mine floor. Small bunds, garlands and silting tanks also will be constructed to
minimize inflow muddy water which carry fine material.
3.4.2 Impact on Ground Water
Mining activity will be above the BWL (55 m). Hence, there will be no effect on the
ground water regime.
3.4.3 Impact on Water Quality
Water quality in the buffer zone have indicated that the ground water is free from heavy
metal concentration and this mining activity will not interference on the water quality.
3.4.4 Water Consumption & Wastewater Generation
The water requirement for this proposed mining activity will be 08 KLD. Breakup details
are:
Sl. No: Purpose Quantity (KLD)
1 Dust suppression purpose 06
2 Domestic purpose 1.0
3 Greenbelt purpose 1.0

3.5 LAND ENVIRONMENT
Various components of land environment have been identified for study of impact of the
mine operations. Details of the same are given below:
Existing land use pattern:
The subject area is a barren land with exposures of deposit and sheet rock; areas around
the hill are barren lands. These lands are not use for agriculture.
3.5.1 Solid Waste Generation
Removal of weathered rock and the rock waste is the only solid waste that will be
generated from this mine. Some of the material from the waste may be sorted out and
used for making small blocks to be used by the local unit for making tiles. The market for
tiles is good at the moment and they will offer a better substitute for marble in terms of
price and quality. Some rejected and unsorted material may be used in the civil
engineering projects in the vicinity of the area. The waste material can also be crushed
into smaller sizes and can be used as road metal
About 80 % @ 68088 m3/Year of waste will be generated from this mine. The waste
generated will be dumped along the south west (approved mining plan plate V) boundary
of the quarry lease applied area (within the quarry lease applied area).
Dump management : The waste generated will be dumped along the southwest boundary
of the quarry lease applied area (within the quarry lease applied area) with an average
height of 20 m with 45o slope angle will be formed. A garland drain will be constructed
around the dump for preventing the slanting of boulders.
It is estimated that in the next five years a total of 3056512.68 T of waste is expected to
be generated with an average of 268392 m3 per annum. The year wise waste generation
in next 5 years is as follows:

possible to complete regain the original topography of the area. During quarrying
whatever solid waste is generated shall be dumped at dumping site in outside the Q.L.
area. The mining lease area is not a part of any type of forest. Entire mine lease area is
govt. land hence all the impact on land use is positive because aesthetic environment will
not be effected, as the mine is located on a plain with some bushes.
There is no forest area located within 10 km from the lease boundary.
Due to opencast mining activities, the landscape will be slightly changed. There
will be no land subsidence as the country is made up of hard rock. The Soil cover in this
mine is almost nil and Agriculture is seen mainly in the plains in the vicinity of the lease
area and the mining will not have any impact on the agricultural pattern. Only few bushes
will be cleared to facilitate mining and other related activities and there are no big
trees, which may have to be cut.
3.5.3 Impact of Ground vibrations
Fragmentation of rock by blasting is an important operation in mining project, where hard
rock occurs. Blasting will be done only when it is absolutely necessary, using low
intensity explosives.
Blasting of the mineral at the proposed mine will be done by using Low-density
chemical explosives like ECM/ CaOH will be used. Sometimes smooth blasting may be
done using silent non-explosive demolishing agents like Acconex.
The ground vibrations caused by blasting will not have any affect as the mining is on a
mound and the vibrations will be minimum and will not be carried too far due to the hard
nature of the rock.

3.6 BIOLOGICAL ENVIRONMENT
There is no adverse impacts are anticipated due to the proposed mining activity on
biological environment. However, with the implementation of the environmental
management measures, there will be improvement in the parameters of biological
environment.
The tree species found with the core zone represent the common type of flora species
along with small shrubs and bushes. Due to mining activities community structure of the
vegetation will not change. Whereas diversity of plant species and food web index of the
area reduced to certain extent.
However, if the proposed reclamation of the mining area and dumped out area using
proper re-vegetation techniques and development of green belt around the ultimate limit
and roadside there shall be an improvement in the species diversity and food web index
compared to the existing level.
3.7 SOCIO- ECONOMIC ENVIRONMENT
3.7.1 No Rehabilitation
The mine area does not cover any habitation. Hence the mining activity does not involve
any displacement of human settlement. No public buildings, places, monuments etc. exist
within the lease area or in the vicinity. The mining operations will not disturb/ relocate
any village or need resettlement. Thus no adverse impact is anticipated.
3.7.2 Improvement in Socio Economic Status
It will be obvious to assume that the activities of the mining operations have to be
produced some improvements in the socio-economic levels in the study area.
The Lessee will provide employment to local population and it will give preference to the
local people whenever there is requirement of manpower.
The proposed mining activities will provide employment to persons of different skills and
trades. The local population is the largest plausibility among these employees. The

employment potential ameliorated economic conditions of these families directly and
provided employment to many other families indirectly who are involved in business and
service oriented activities. This in-turn will improve the socio-economic conditions of the
area.
3.7.3 Occupational Health and Safety
The mine is going to be developed mainly semi mechanized opencast method by using
jackhammer drilling & wire saw cutting & low explosive blasting. No major crushing or
pulverization will be done here. The small-scale mining will not have any ill effects on
the health of labour.
Excessive dust and noise are the chief health hazards for the miners. As already
mentioned these causative factors are well within the safety limits and the proponents
will strictly implement the prescribed safety measures. The health of the workers will be
regularly checked and suitable medical facilities should be created on or close to the site.
Highest safety will be ensured in the working conditions of the miners.

4. ENVIRONMENTAL MANAGEMENT PLAN
4.1 INTRODUCTION
The mining development in the study area needs to intertwined with judicious utilization
natural resources within the limits of permissible assimilative capacity. The assimilative
capacity of the study area is the maximum amount of pollution load that can be
discharged in the environment without affecting the designated use and is governed by
dilution, dispersion and removal due to natural physio-chemical and biological processes.
The Environmental Management Plan (EMP) is required to ensure sustainable
development in the study area.
This chapter covers the genesis of pollution, the principal sources of pollution, the nature
of pollution, the proposed measures required for meeting the prevailing statutory
requirements of gaseous emissions, wastewater discharge characteristics, noise levels etc.
for environmental management purpose in connection with the mining and mining related
activities in the study area.
This section discusses the management plan for mitigation/abatement impacts and
enhancement of beneficial impacts due to mining. The Environmental Management Plan
(EMP) has been designed within the framework of various Indian legislative and
regulatory requirements on environmental and socio-economic aspects.
Environmental Management Plan giving the environmental protection measures at mine
to meet the stipulated norms of IBM/MoEF are as detailed.
4.2 AIR POLLUTION CONTROL MEASURES
The present ambient air quality measurements in the mine area are well within the limits.
Due to the proposed production of 17022 Cum/Year of colour granite, there will be
marginal increase in dust concentrations.
EMP Report For Colour Granite Mine of 7.850 Ha, located in Jarali Village, Sarvakota Mandal, Srikakualm District, A.P.
Sri Choudhry Suresh
Global Enviro Labs, Hyderabad 23
Mitigative measures suggested for air pollution control are based on the baseline ambient
air quality monitoring data. From the point of view of maintenance of an acceptable
ambient air quality in the region, it is desirable that air quality should be monitored on a
regular basis to check it vis-à-vis the standards prescribed by CPCB and in cases of non-
compliance appropriate mitigative measures shall be adopted.
The following dust prone areas are identified for adopting proper control measures in the
mine area.
i) Drilling & Wire Saw Cutting & Blasting
ii) Excavation
iii) Transportation
The environmental control measures which will be implemented to control the fugitive
dust released from the proposed production are given below:
Wet drilling system & Dust proof
Optima Wire Saw Cutting (using water reduces dust)
Use of sharp drill bits for drilling holes. The charge concentration of the
explosives will be between 10 – 40 grams per linear meter.
Water sprinkling arrangements such as specially fabricated tankers mounted on
tipper are deployed at mine site to control the fugitive dust generation from the
haulage roads.
Regular grading of haul roads and service roads to clear accumulation of loose
material
The blasted blocks (temporary) are wetted by spraying water
Avoiding blasting during high windy periods, night times and temperature
inversion periods.
Excavation operations are suspended during periods of very strong winds.
Massive afforestation for control of dust
Spraying of water on sub grade stacks

The vehicles and machinery are kept in well-maintained condition so that
emission of fugitive constituents is minimized.
Plantation of wide leaf trees, creepers, tall grass around working pit, along roads
will help suppress dust.
Tall trees with an average height of 5 m will be developed all along the boundary
of the lease area to minimize the dispersion of the dust from the mining.
Periodical monitoring of air quality to take steps to control the pollutants.
4.2.1 OCCUPATIONAL HEALTH & SAFETY MEASURES
All the precautions would be adopted to prevent dust generation at site and to be
dispersed into the outer environment. However, for the safety of workers at site, engaged
at strategic locations/dust generation points like drilling, loading and unloading points,
etc., dust masks would be provided. Dust masks would prevent inhalation of RSPM
thereby reducing the risk of lung diseases and other respiratory disorders. Regular health
monitoring of workers will be carried out.
4.3 NOISE POLLUTION CONTROL MEASURES
The ambient noise level monitoring is carried out in and around the proposed mine shows
that ambient noise levels are well within the stipulated limits of CPCB.
Noise generation may be for an instant, intermittent or for continuous periods, with low
to high decibels. Periodic inspection and checks of the risk prone areas and equipments
have to be conducted.
To control noise pollution during the proposed mining operations following steps will be
practiced.
The noise generated by the machinery will be reduced by proper lubrication of the
machinery and equipment.
The workers employed should be provided with personal hearing protection
equipment, with earmuffs and earplugs combined, as a protection from the high
noise level generated at the plant site.
EMP Report For Colour Granite Mine of 7.850 Ha, located in Jarali Village, Sarvakota Mandal, Srikakualm District, A.P.

The provision of green barrier along the boundary will further reduce the
propagation of noise level generated.
Limiting time exposure of workers to excessive noise.
Speed of trucks entering or leaving the mine is limited to moderate speed of 25
kmph to prevent undue noise from empty tippers.
Safety in Blasting:
Care should be taken to evacuate the mining area completely at the time of low explosive
blasting operations. The blasting team should be equipped with all personal safety and
precautionary measure. The following safety measures will be given attention while
conducting the blasting operations.
A blasting SIREN should be used at the time of blasting for audio signal.
Before blasting and after blasting, red & green flags should be displayed as visual
signals.
Warning notice boards indicating the time of blasting and NOT TO TRESPASS
are displayed prominently.
4.4 WATER POLLUTION CONTROL MEASURES
The action program for minimizing adverse affects on water regime is to prevent wash-
off of mine water and uncontrolled run-off water during monsoon. Proposed measures for
this are as follows:
Building/extending of retention/toe walls at the foot of the dumps
Construction of Garland drains along the slopes to divert the rainwater course
away from the dumping areas.
Covering of dump slopes with grass plantation to stabilize and prevent
erosion.
Plantation of trees along the ridges and slopes.

4.5 LAND ENVIRONMENT
The Dhanbad declaration on Environmental Management in Mining Industry states “It is
imperative that in order to ensure the continued and sustained progress of the mining
industry in India, the environmental dimensions should be integrated into the planning,
design, development, operation and working practices of quarry on scientific and rational
lines, by the Governments and the industry in a mutually reinforcing manner”. The land
related Environmental Management Plan (EMP) has been presented here under two
sections viz., Soil & Water conservation and Afforestation.
Storage and Reuse of Top Soil:
Topsoil removed during clearing of the area for granite extraction shall be stacked
separately to check the erosion of the stacked soil. A retaining wall shall be constructed
all around the topsoil stockyard. Planting of grass and local species etc., are proposed on
the surface of this stack to prevent erosion and to increase the soil nitrogen. As per the
analysis of the soil samples they are found to be basic in nature. During afforestation, it is
recommended to plant fast growing species with good canopy cover and dense leaf
density and some ornamental species to give a good aesthetic look. It is recommended to
sow neem, mahogany plants as soil and climatic conditions are suitable for the growth of
these plants.
Solid Waste Management
Removal of weathered rock and the rock waste is the only solid waste that will be
generated from this mine. Some of the material from the waste may be sorted out and
used for making small blocks to be used by the local unit for making tiles. The market for
tiles is good at the moment and they will offer a better substitute for marble in terms of
price and quality. Some rejected and unsorted material may be used in the civil
engineering projects in the vicinity of the area. The waste material can also be crushed
into smaller sizes and can be used as road metal

About 80 % @ 68088 m3/Year of waste will be generated from this mine. The waste
generated will be dumped along the south west (approved mining plan plate V) boundary
of the quarry lease applied area (within the quarry lease applied area).
Dump management : The waste generated will be dumped along the southwest boundary
of the quarry lease applied area (within the quarry lease applied area) with an average
height of 20 m with 45o slope angle will be formed. A garland drain will be constructed
around the dump for preventing the slanting of boulders.
It is estimated that in the next five years a total of 3056512.68 Cum of waste is expected
to be generated with an average of 268392 m3 per annum.
Land Restoration/Reclamation:
Land restoration or reclamation of the area is very essential in any mining industry.
Proper measures adopted during restoration will control most of the adverse
environmental impacts of Quarry and also improve the aesthetic beauty of the area. Due
to the Quarry activities in this area the profile of the ground will change due to formation
of pits. At the end of the Quarry operations, the top soil/mineral rejects will be utilized
for back filling wherever suitable and rehabilitated.
Following steps shall be taken for improving and protecting the environment.
a) Quarry lease area
b) Surrounding the Quarry lease area.
c) Surrounding the statutory buildings
d) On the undisturbed virgin lease area.
Surrounding the Mining area
The dust generated during the quarrying operations will be carried by wind and will be
deposited over the trees and on the adjacent area around the quarry in the buffer zone. To
filter this dust, a green belt of 10m width shall be developed along the quarry lease area
i.e., around ultimate pit limit, this green belt will also act as sound barrier. In between the
tree saplings, grass and bushes shall be grown. Creation of the green belt around the lease
areas shall be undertaken on priority basis and shall be completed concurrent to Quarry
over a 10-year period.

Surrounding the statutory buildings
All around the proposed statutory buildings and along the road sides trees shall be planted
in addition to the existing ones which will protect the workers from the noise and dust.
To plant trees around the statutory buildings, the topsoil that is going to be mined from
the area shall be laid to form a strip of 10-15m width and 0.5m thickness.
On the undisturbed virgin lease area:
The undisturbed virgin lease area shall be utilized for afforestation purposes by
developing the area with local varieties. This work shall be done after the cessation of
Quarry operations.
Green Belt Programme:
Each year some part of the barrier zone will be subjected to afforestation and care will be
taken to protect the sapling. Neem,Mango and Fruit growing trees are proposed to
planted. The table below shows the afforestation plan.

Apart from the green belts and aesthetic plantation for eliminating fugitive emissions and
noise control, all other massive plantation efforts shall be decided and executed with the
assistance and co-operation of the local community. Based on the community needs the
afforestation would mainly aim at:
a) Protection & Development of Natural Vegetation
b) Protection of soil erosion
c) Plantations of fuel wood blocks to meet the energy requirements.

4.6 SOCIO ECONOMIC BENEFITS
There is positive impact on socio-economics of people living in the villages. The villages
in buffer zone depend upon agriculture. Mining operations in the subject area has positive
impact by providing direct and indirect job opportunities. There will be indirect
employment opportunities in transportation of ore to destination.
4.7 POST PROJECT MONITORING
The Lessee will monitor the environmental parameters as per APPCB/IBM/CPCB
guidelines
4.8 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 mine 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.

CONCLUSIONS, SUGGESTIONS/RECOMMENDATIONS
The Mining method proposed as per the approved Mining Plan from Dept. of Mines &
Geology is small-scale semi mechanical mining activities without deployment of deep
hole drilling and use of Heavy machinery. The actual method of mining Colour Granite is
by slicing. Based on the appraisal of the existing environmental scenario coupled with
the assessment studies carried out, it is concluded that there is no long term
environmental impact due to the Colour Granite quarry at the lease area.
The particulate matter getting airborne from the mining activity gets dispersed in close
proximity itself and settles down early. The noise levels due to the proposed quarry
activity are also not of a higher order that calls for immediate corrective measures. The
ground water analysis indicates that the sources do not get influx of pollutants from the
quarry activity. There is positive socio-economic front in the surrounding region due to
the proposed mining industry. The practice of afforestation scheme is a step in the right
direction towards achieving ecological balance.
Suggestions/Recommendations
Even though there is no perceptible impact from the quarry activity on the environment of
the region, it is imperative that mitigative measures have got to be implemented on full
scale for creating environmental balance and intern maintain the ecology of the region.
The following suggestions/recommendations merit due consideration in this regard.
As no control over wind can be exercised, the frequency of the dust
suppression measures like constant watering of the haul roads shall be
practiced.
Afforestation as envisaged in the mining plan is to be carried out so that it
not only enhances the green canopy but also stop the spread of dust
particles and air borne pollutants.
Surface water conservation measures and groundwater recharge be given
high priority.
