1.1 Granite and its uses
Granite is a very common intrusive igneous rock. It is light-colored granulose plutonic rock
composed of the minerals feldspar, quartz and biotite & muscovite mica. These minerals
make granite white, pink, or light grey. Granite also contains small amounts of dark brown,
dark-green, or black minerals, such as hornblende and biotite mica. Granite is very hard and
dense. It can be readily cut into very large blocks and it takes an extremely high polish. The
name granite is derived from the Latin word granum, which means grain, an obvious
reference to the granular texture of granite. The average density of granite is between
2.65 and 2.75 g/cm3, with a compressive strength of above 200 Mega Pascal (MPa).
Uses
Granite has been extensively used as a dimension stone and as flooring tiles in public and
commercial buildings and monuments. With increasing amounts of acid rain in parts of the
world, granite has begun to supplant marble as a monument material, since it is much more
durable. Engineers have traditionally used polished granite surfaces to establish a plane of
reference, since they are relatively impervious and inflexible. Granite tables are used
extensively as a base for optical instruments due to granite's rigidity, high dimensional
stability and excellent vibration characteristics. Rough-cut and polished granite is used in
buildings, bridges, paving, monuments and many other exterior projects. Indoors, polished
granite slabs and tiles are used in countertops, tile floors, stair treads and many other
practical and decorative features. Presently, cut and polished granite slabs of 20 mm
thickness are preferred for flooring, while tiles of 10 or 12 mm thickness are used for
cladding.
1.2 Mining Technology
The mining operations are carried out by manually and semi-mechanization as opencast
mining. The Colour Granite in the quarry lease applied area is exposed on the surface with
boulders. (Hence, it is proposed to mine the boulders/sheet by opencast, semi- mechanized
methods, by developing the benches of 3m height). Wire Saw cutting will be deployed based
on the favorable conditions. The development of benches in the sheet rock will be
maintained @ 60° safety slopes.

2.1 Regional Geology
The Eastern Ghat Mobile Belt is a high grade terrain along the east coast of India and
bounded to the north by the Singhbhum crater and to the west by Bastar craton, the
Dharwar craton and Nellore - Khammam schist belt. Nanda and Pati (1989) and Ram
Krishnan et.al. (1988) on the basis of dominant lithological assemblages of Eastern ghat
belt. Longitudinally divided into following four (4) zones.
i. Western Charnockite Zone
ii. Western Khondalite Zone
iii. Central Migmatite Zone
iv. Eastern Khondalite Zone
Recent works by Chelty et.al 2001, 2003 helped in identifying leptynites and shear zone in
Eastern ghat belt and there by sub divide the EGB to several structural domains viz.
a) Eastern Ghat Boundary Shear Zone
b) Sileru Shear Zone
c) Koraput - Sonpur Shear Zone
d) Nagavalli - Vamsadhara Shear Zone
The area lies between Sileru shear zone in the west and Nagavalli - Vamsadhara Shear zone
is identified as Eastern ghat provides with specific Lithology, structure and metamorphic
grade. The area from Salur in the North - Rajahmundry in the south including Aruku -
Paderu in the west and Vishakhapatnam - Vizianagaram comes in Eastern ghat provides
area with principle litho unit like Khondalite, Charnockites, Leptynite and calc granulite.
2.2 Local Geology
Leptinite occurs as large enclaves in Porphyroblastic Charnockites which are commercially
named as Kashmir White / Snow White. Leptinite essentially consists of Milky White Quartz
and Feldspars with accessory minerals like Pink - Brown Garnets and Black Biotite, which
occur as Stringers. These Leptinites are very Fine Grained with Sachroidal in Texture. The
garnets occur with sizes ranging from 1 mm - 1 cm, showing Spheroidal / Oval shape

In the quarry lease applied area the Leptinite occurs as small mound type exposure raised
72m above ground level. 4 out crops of Leptinite observed separated by soil cover area. The
Leptinite are interred tongued with porphyroblastic migmatites. The rock showing well
developed foliation with brownish red garnets forming the banding. The foliation trending in
N 70° E - S 70° W, caught up patches of dark coloured porphyroblastic migmatite are also
trending in N 70° E - S 70° W. Pegmatite veins of 30 to 40 Cu. m wide intruded into Leptinites
trending in N 45° E S 45° W dipping East
3.0 Exploration
a) Mining Carried out
The colour granite deposit forming a hill, raised 40m above ground level within the quarry
lease area. No mining is carried out in this area.
4.0 Reserves
Geological traverses in the quarry and the study exposures in the quarry facilitated to access
the shape and size of the deposit in the area. It is a mound deposit raised 40m above ground
level. The surface of sheet rock is wavy and irregular.
4.1 Estimation and Calculation of Geological Reserves
The exposed granite deposit is found to be irregular in shape, the volume of the deposit is
computed by cross sectional area method by multiplying the cross sectional area with the
proved depth upto RL 150m. 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 is multiplied by the sectional influence of 50m (Average)
to arrive the volume of rock mass. Since the recovery of the marketable blocks and tiles in the
previous years is low, a conservative recovery of 20% rough blocks. The cross sections in N - S
direction are drawn at equal interval of 50m. 6 Cross Sections A-A1 to G-G1 was drawn.
Section wise calculation of colour Granite reserves are given in the table 1.3.

5.0 Mining
a) Type of Mining:
The Colour Granite in the quarry lease applied area is exposed on the surface with boulders.
(Hence, it is proposed to mine the boulders / sheet by open cast, semi- mechanized methods,
by developing the benches of 3 M height). Wire Saw cutting will be deployed based on the
favorable conditions. The development of benches in the sheet rock will be maintained @ 60°
safety slopes. The separation of blocks from the mother rock will be carried out by drilling,
wedge cutting, blasting; excavation will be done by the machinery. The secondary splitting,
dressing of blocks will be done manually.
Therefore, mining operations are to be carried out in this area in 2 stages.
i. Development
ii. Production
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, blasting 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 hole intersecting these two holes and wire
saw 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.
Stage - 2
After removal of weathered and under sized boulders.
a. 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.
b. The burner cutters will be deployed for shaping the boulders.
c. 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.
K. Garuda Reddy Environment Management Plan
Team Labs and Consultants1-10
d. 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 90°.

Drill holes of 9m depth will be drilled in a single row with spacing of less than 0.3m and
burden of 1.6m or more shall be maintained uniformly. This arrangement will yield rock size
of 3m x 2m cross section. A bench height of 6m will be tackled in two steps.
K. Garuda Reddy Environment Management Plan
Team Labs and Consultants1-12
6.2.1 Drilling Parameters
i. Drill holes diameter – 32mm upto 9m long.
ii. Depth and inclination of the drill hole: Generally drilled vertically in an alignment,
however in primary cutting in the absence of sheet joints to develop bottom level
horizontal holes also be drilled.
iii. Explosive Type: Not Applicable (No permission for storing the blasting material will be
granted by the District Administration). The applicant proposes to use AGFRACT Chemical
Compound whenever required. Hence, no magazine is proposed.
6.3 Dressing
After primary separation the rock mass will be carefully examined to avoid hairline cracks,
mineral segregation’s and veins etc. The dressing of the rough blocks will be made by
chipping the edges and geometrically equating the edges of the block at the dressing yard.
The rough blocks obtained after primary cut it will be dressed for obtaining good geometric
shape of colored granite.
Dressing of dimensional rough blocks for export:
Dressing is the 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
the equipment generally used for dressing the block.
6.4 Magazine type and capacity
Not Applicable (No permission for storing the blasting material will be granted by the District
Administration). The applicant proposes to use AGFRACT Chemical Compound whenever
required.
6.5 Solid Waste
The granite body exposed to the surface. Hence, the weathering on the surface of the rock
closely spaced joints and shears along with inherent defects like Moles, Dark patches and
acidic veins contribute a large extent of waste generation during the mining. The waste
generated will be dumped in the western boundary of the quarry lease area covering an area
of 3300m2 with an average height of 30m with 45° slope angle will be formed. A retaining
wall will be constructed around the dump for preventing the slanting of boulders. It is
estimated that in the next four years a total of 21345m3 of waste is expected to be generated

9.0 Environment Management Plan
Environmental protection is an issue that no organization can neglect and hope to survive.
The products of civilization are being dumped upon the environment to a degree that the
environment finds difficult to assimilate. The key to the success of the integrated approach to
pollution prevention and control is the management and operation of the organization.
Effective committed management delivers a successful operation. As total commitment to
the environment, not just for compliance with legal or regulatory compliance will be the
essence of environment management. Many companies have recognized the benefits of
implementing an effective environmental management system.
K. Garuda Reddy Environment Management Plan
Team Labs and Consultants1-14
Environmental management plan can be effectively implemented to mitigate the pollution
levels by observing the following:
a. Pollution will be prevented or reduced at the source
b. Pollution that cannot be prevented will be recycled in an environmentally safe manner.
c. Pollution that cannot be prevented or recycled will be treated in environmentally safe
manner and
d. Disposal and other releases into the environment will be used only as a last resort and
will be conducted in an environmentally safe manner.
The proposed project is granite mine. The mine owners are aware of the adverse impacts due
to the mining activity and propose to initiate a number of measures for the environment
protection within the mine area and in the surrounding areas. The company has a stated
environmental policy of ensuring regulatory compliance with respect to the statutory laws
and regulations and those periodically issued by the Ministry of Environment, GOI, New
Delhi, CPCB, New Delhi and State Pollution Control Board.
9.1 Sources of Pollution and Control Measures
The sources of pollution are air and noise from the proposed activity mainly from Mining,
drilling, Blasting and transportation of mineral. Waste material generation, dumping and
restoration.
9.2 Air Pollution and its Control
The granite mining does not involve much dust formation. The dust would be generated
during drilling, blasting, quarrying and also during handling and transportation of the
material. The dust anticipated at drilling place will be suppressed by putting cloth around the
hole. Use of sharp drill pits for drilling holes and drills with water flushing systems (wet
drilling) to reduce dust generation. Water spraying to be adopted at Faces/sites before and
after blasting, Faces/sites while loading. Over charging of blast holes should be avoided.
Personal protective equipments like nose mask and goggles etc will be provided to the
workers. Regular water spraying on haul roads during transportation of mineral and waste by
water sprinklers. Over loading of transport equipments should be avoided to prevent spillage.
Also, measures such as covering tarpaulin over the loaded material will prevent spreading of
dust particles from the trucks. Speed controls on vehicle movements to limited speed. Wind
reduction control by plantation. Over burden dump has reached the optimum size, it will
K. Garuda Reddy Environment Management Plan
Team Labs and Consultants1-15
covered with top soil and water will spread on top soil and grass will be developed on the
dump. Limiting the height and slope of the stockpiles can also reduce wind speed. Regular
checking and maintenance of vehicles should be conducted and pollution under control
certificate be obtained. Periodical monitoring of ambient air quality will helps to take steps to
control the pollutants.
9.3 Noise pollution and its control
The major source of noise pollution is due to drilling of drill holes, machinery, Blasting and
vehicular movement. Blasting operations will be carried out only during daytime so as to
avoid high noise intensity in night time. Noise barriers in the form of trees are provided to
attenuate the noise levels and green belt of 3m width shall be developed to mitigate
propagation of noise. Protective equipment to reduce the noise levels like ear muffs and
other protective devices will be provided to the staff working near noise generating sources
like drill machine operators and dumper drivers. Training would be imparted to mine
personnel to generate awareness about the damaging effects of noise. The transport activity
shall be restricted to day time to reduce impact on habitation. The engines of the tractors
shall be switched off during loading operation, and shall be periodically maintained to ensure
low noise levels. Proper maintenance of the equipment will also reduce the noise.
10.0 Occupational Safety and Health
Health and safety aspects of the mine will be taken care off as per the World Bank (WB)
guidelines on open pit mining. The guidelines provide the detailed information on the aspects
that are required to be taken into account for maintaining proper health and safety issues.
The workers continuously exposed to dust will be provided with protective devices like dust
mask to prevent respiratory disorders. The workers continuously exposed to a high noise will
be provided with ear muffs/ earplugs. Green belt in and around the mining area will be
developed to attenuate noise and dust impact. The blasting carried out in the mine area will
be carefully planned and executed under the supervision of a responsible officer, to avoid any
accidents. Provisions of rest shelter for mine workers with facility of drinking water supply for
the employees will be provided by the project authority. The standard of the drinking water
will be per WHO guidelines. Periodical training program to inform the employees about their
task, associated risk, and safe working practices will be undertaken. Conduct of mock drill,
Safe storage & handling of explosives. Training will also include information on accident
K. Garuda Reddy Environment Management Plan
Team Labs and Consultants1-16
prevention, proper control and maintenance of equipment and safe material handling
practices. Awareness on safety and ensure using of personal protective equipments (PPE) by
workers. Regular maintenance and testing of equipments will be done. A regular monitoring
of the Occupational Health and Safety will reduce the chances of accidents in the mine.
Records of job related accidents and illness should be maintained. This information will be
reviewed and evaluated to improve the effectiveness of Environmental Health and Safety
program.
Occupational Safety and Health to Control Dust Inhalation
Very little dust is expected to be generated during mining and does not affect the
environment. However while drilling, wet drilling will be practiced. It is a small scale mining
activity and not much vehicular movement is expected. 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 the strategic locations/dust generation
points like drills, loading & unloading points 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.
10.1 Occupational Safety and Health to Control Exposure to Noise
Blasting will be done using non delay detonators to reduce vibrations, and the amount of
explosive used will also be less at a time. There will not be heavy earth moving machinery
which may create some noise pollution. Thus the vibration and noise will be well controlled
within permissible limits. To protect the workers from exposure to high levels of noise,
following measures would be adopted:
Provision of protective devices like ear muffs/ear plugs to workers who cannot be
isolated from the source of high intensity noise, e.g. blasting;
Reducing the exposure time of workers to the higher noise levels by shift management.
Smooth blasting techniques, special explosives and silent non-explosive demolishing
agent will be used.
Muffed blasting and use of Milli-second detonators will help in reducing the noise
pollution.
K. Garuda Reddy Environment Management Plan
Team Labs and Consultants1-17
10.2 Control of Ground Vibration & Fly Rock generation
It is proposed to use low explosives and less quantity to minimize the effects so that the
vibration generated will be feeble within 8 Hz. General Measures to reduce ground vibration
& fly rocks resulting from blasting are given below:
Blasting should be carried out in the daytime, as during the night time the sound intensity
becomes higher;
Blasting should not be carried out when strong winds are blowing towards the inhabited
areas;
Maximum permissible charge per delay should be decided on the basis of the distance of
structure to be protected from the blasting.
The number of rows in a blast should not be more than four so that fly rock generation
and ground vibration is reduced.
Peak particle velocity or ground vibrations for safety of nearby structures and
residential buildings should be well within 12.5 mm/sec;
To contain fly rocks, stemming column should not be less than the burden of the hole,
and the blasting area should be muffled;
Each blast should be carefully planned, checked, and executed under the supervision of a
responsible officer. Blasting data/observations should be recorded; and
As per the mining plan, in order to ensure slope stabilization, controlled production blasting
shall be adopted to avoid tension cracks and back breaks. Such cracks may get filled with
water, which reduces the stability of excavated slopes and the angle of slopes.
11.0 Peak Particle Velocity
The vibrations are measured as per the assessment criteria given under Bureau of Indian
Standard, “IS: 6922-1973 (Reaffirmed 2003) - Criteria for Safety and Design of Structures
Subject to Underground Blasts”.
Per the assessment criteria, the value of particle velocity may be computed from the
following expression:
V = K1 [Q2/3/R] 1.25
Where
V = Particle velocity in mm/sec
K1 = Constant which may be normally taken as 880 for soil, weathered or soft rock
K. Garuda Reddy Environment Management Plan
Team Labs and Consultants1-18
and 1400 for hard rock.
Q = Charge per delay (kg), and
R = Distance (m) from blast point
Based on the above equation, the particle velocities at different distances (3 m, 5 m, 10 m, 20
m, 50 m, 70 m, 100 m, 150 m and 200 m) are calculated considering K1 as 880 for soft rocks
and 1400 for hard rocks. As per the Standard, for safety of structures from threshold damage,
the ground particle velocity should not exceed the following:
Soil, Weathered or Soft rock 70 mm/sec
Hard Rock 100 mm/sec
The results are presented in the Table 1.7 below for the maximum charge
Table 1.7 Peak Particle Velocity (V)

mm/sec in soft rock within a distance of 70m while in the hard rock the ground particle
velocity is 1.16 mm/sec shall be within 100m. There shall not be any structure with in 70 m of
the quarry area, and it may be, concluded that the ground vibrations generated by blasting
during the mining operations will not likely to effect the structures proposed in the vicinity of
>70 m from the point of blast. Concrete structures like office, store etc should not be
proposed within the core mine area. These structures otherwise will be affected by the
ground vibrations.
12.0 Water Quality Management
There is no chemical discharge either from the quarry or from the processing quarry, there
will not be water pollution. The proposed quarry workings will not touch the ground water
aquifer. Quarrying Operations will be carried out on the slope of the Rocky terrain. The
ground water level in this area is 7m BGL and the quarrying will be done on above the surface
level. Maximum depth of the quarry will be 12m from top of the hill and height of the hill is
40m, flooding by ground water is not anticipated. Hence neither ground water table nor the
general surface drainage pattern is affected Hence there will not be water pollution. There
will be no change in quality of water. However during rainy months, there is a possibility of
K. Garuda Reddy Environment Management Plan
Team Labs and Consultants1-19
wet conditions developing in the working pit this will be minimized, if not altogether
eliminated, by adopting simple techniques like digging trenches all round to drain off
rainwater and preventing surface run off from entering and flooding working pit. The water
from the pits will be pumped by deploying suitable pumps, if and when required, the mine
drainage can be effectively managed and the pit kept dry to keep up the production
schedule.
12.1 Water Resources
In this area water table is at greater depth of 7m BGL and the workings are carried out on top
of the hill which is at 40m height. There are no wells or springs in the area. Hence there will
not be adverse effect on ground water due to quarrying. The daily water requirement for the
quarry operations would be approximately 4.2 KLD. Water sprinkling on mine haulage roads
etc shall consume 1.4KLD. Wet drilling operations consume about 0.7 KLD. For green belt
development water consumption is about 0.8 KLD. Domestic purpose is about 1.3 KLD. The
water is to be sourced from nearby village through tankers. The generation of wastewater
from domestic sources is expected to be approximately 0.9 KLD, which will be sent to septic
tank followed by soak pit.
12.2 Water Management
Following measures will be adopted to mitigate the impact on the water resources:
The blasting activities will have to take care on the sinkholes, cracks and fissures in the
site activities.
During excavation and drilling activities effort must be taken to avoid face collapse at
these cracks and fissures.
To prevent surface water contamination by oil/grease, leak proof containers shall be
used for storage and transportation of oil/grease. The floors of oil/grease handling area
will be kept effectively impervious.
To prevent degradation and maintain the water quality during rainy season, adequate
control measures should be adopted to check the mine run-off into the natural streams.
12.3 Catchment Area Treatment Plan
A catchment area treatment plan has been developed keeping in mind the results of the
hydrology/ hydrogeology of the area and the climate data. As there are no perennial water
sources running on or through the site, the mine water discharge is limited to the monsoon
K. Garuda Reddy Environment Management Plan
Team Labs and Consultants1-20
season only. To keep water from entering the mine during this period, a garland drain will be
developed along the mine’s top bench, which will bend to guide the water to the nearest
natural surface drain. In terms of water quality, good mining practices are planned,
additionally the natural state of surrounding areas, should ensure that rain water run-off
from the mine does not contain any toxic elements. As the site has no overburden, potential
discharge of sediments is quite limited and any residual particles which are washed down will
be captured by a sump located at the lowest bench. The sump will be cleaned regularly and
discharge water monitored consistently. If required, based on monitoring, an additional catch
pit can be located at the main garland drain. The sump proposed in the bottom bench will be
designed based on the peak discharge and will be expanded over a period of time to
accommodate the increasing quantum of water discharge. Presently, the capacity of the
sump is designed to hold the entire quantum of peak discharge water for more than 10
minutes. The garland drain shall be provided surrounding the mine area. Garland drain and
siltation pond need to be constructed of appropriate size to arrest silt and sediment flows
from soil and mineral dumps. The water so collected will be utilised for watering the mine
area, roads, green belt development etc. The drain should be regularly desilted and
maintained. The garland drain (size, gradient and length) and sump capacity will be designed
keeping 50% safety margin over and above the peak sudden rainfall and maximum discharge
in the area adjoining the mine site. Sump capacity should also provide adequate retention
period to provide proper settling of silt material. The surface water around the mine, and
infrastructure will be regularly tested and appropriate control measures adopted in case of
any pollutant is detected above the prescribed limits.
13.0 Waste Management plan
During this plan period operations a total rock mass of 26682 3m will be excavated and
5336.4 3m of granite blocks will be recoverable from this rock mass and remaining material of
about 21345.6 3m will go as mineral waste. There is no overburden on the deposit. Boulders
are exposed on top of the colour granite.
14.0 Dump Area
The waste generated will be dumped in the middle northern of quarry lease applied area
covering an area of 3300m2 (0.33ha) with an average height of 30m with 45° slope angle will
be formed.
K. Garuda Reddy Environment Management Plan
Team Labs and Consultants1-21
14.1 Land Management
Land degradation is one of the major adverse impacts of opencast mining in the form of
excavated voids and also in the form of waste dumps. Land reclamation plan must, therefore,
be implemented simultaneously with the mining activities.
14.1.1 Land Reclamation
No reclamation proposals are made. The pits that will be developed will be converted into
water harvesting structure.
14.1.2 Soil Conservation Measures
The applied area is part of hill raising 40m above ground level. In quality, the soil existing in
the area is hard and unfertile. Therefore, the growth of trees and plants is uncertain and not
satisfactory. Hence, in this area few small plants and thorny trees are grown here and there.
Except this, no big trees are seen in this area. Top soil, if any will be properly stacked at
earmarked dump site with adequate measures and the same will be used for reclamation and
rehabilitation of the mined out areas. To prevent soil erosion and wash-off of dump-fines
from freshly excavated benches and dumps following measures shall be adopted:
Garland drains will be provided around the mine wherever required to arrest any soil
from the mine area being carried away by the rain water;
Toe drains with suitable baffles will be provided all along the toe of the soil dumps to
arrest any soil from the dump slopes being carried away by the rain water;
Loose material slopes will be covered by mineation by making contour trenches at 3-5 m
interval to check soil erosion both due to wind and rain;
Retaining walls (concrete or local stone) will be provided, around the stockpile or
wherever required, to support the benches or any loose material as well as to arrest
sliding of loose debris.
15.0 House Keeping
Proper housekeeping and cleanliness will be maintained in the infrastructure facilities. Wet
mopping will be adopted to conserve water. Sign boards will be provided in the work areas
and the road and building highlighting the safety and occupational aspects.
16.0 Transport Systems
Sitabandala to Jaggampeta Village road is passing at a distance of 0.2km in south direction.
Narsipatnam to Waddadi main road is passing at 10.6km in southeast direction. Bayyavaram
K. Garuda Reddy Environment Management Plan
Team Labs and Consultants1-22
railway station is at a distance of 34km in southeast direction. The finished product and
waste material is transported by road using tripper of 18 Tons capacity. The number of trips
will be approximately 1 per three day for transportation of mineral and the tripper is covered
with tarpaulin. The lessee will deploy one tipper to transport the finished product, waste
blocks, unfinished and finished blocks from quarry site to yard and trucks to transport sized
dimensional blocks from yard to destination. Cranes will do the loading of blocks. The
materials while transporting do not pose any hazard. Sufficient parking facilities will be
provided for vehicles loading and unloading of material. Safety signs will be displayed inside
and outside the mine to avoid road accidents.
17.0 Environmental Greening Program
Environmental greening program is an important component of the Environment
Management Plan and is an imperative requirement for sink of air pollutants including noise
as per the guidelines issued by the Ministry of Environment and forests, Govt. of India.
Conceptualization, design and implementation of the proposed activity, taking into account
the specific requirement of the proposed mining activity and the site conditions are
presented. Green cover in mining area not only help in reducing pollution level, but also
improves the ecological conditions and prevent soil erosion to great extent. It further
improves the aesthetics and beneficially influences the microclimate of the surrounding.
During the plan period it is proposed to plant 100m length of 7.5m buffer zone with 3m grid
interval about 85 no. of saplings and 150m length along the road with 2m interval about 40
no. of saplings. Phased plantation will be taken up in this area. The plantation will also be
taken up at the site services, office and on both sides of road. The species that have history of
good survival and growth under similar site conditions shall be planted

The shelterbelt will contain species, which act as windbreakers so that the environment
within the mine is contained; the planting of different species in rows is envisaged in general
in the greenbelt. A dedicated cell in the mine should be established for post plantation care,
which include, regular watering, manuring, protective measures etc. Diseased and dead
plants should be uprooted and replaced by fresh saplings. Regular monitoring on survival rate
and remedial action should be done in an organized and planned manner.
18.0 Socio-economic Environment
The project provides an opportunity for the local people to get employment directly or
indirectly and helps in the upliftment of the socioeconomic status of the area. The proposed
project would generate an employment of 28. The local inhabitants of the area live in the
villages surrounding the mine area and their main occupation is Agriculture. In a small way
they rear cattle and sheep for sustenance. The mining activity in this belt will benefit the
locals both directly and indirectly. The direct beneficiaries will be those who get employed in
the mines as skilled and un-skilled workers. The indirect beneficiaries will be those who open
small business to sell goods required by the residents whose “Per Capita” income will be
enhanced by the mining activity, and thereby their purchasing power. In the long run a lot of
social good is expected in the comparatively backward area when the inhabitants will be able
to send their children to school. The change, though slow, is bound to be perceptible. The
management will involve in social activities of stakeholders/surrounding community by
planning the betterment of neighboring social conditions through awareness and welfare
programs to ensure an improved relation, useful in the long run. Many of the beneficiaries of
such programs will include own employees as well. The goodwill of the local populace can
never be ignored. It is proposed to supply drinking water and medical facilities to the villagers.
The management will also support for vocational training and assistance in utilizing
government programs. The channels employed may vary either through direct contact or by
means of local organizations. Another important facet of social environment identified by the
project proponents is a green appearance; hence the management will develop a green belt
towards aesthetic beautification as the same is necessary to be considered as a responsible,
social neighbour.
19.0 Disaster Planning
The mining operation shall be carried out under the management control and direction of a
K. Garuda Reddy Environment Management Plan
Team Labs and Consultants1-24
qualified mines manager holding a Second class manager’s certificate of competency to
manage a metalliferous mine granted by Director General of mines safety (DGMS). DGMS
have been issuing a number of standing orders and circulars to be followed by the mine
management in case of disaster, if any. Moreover mining staff would be sent to refresher
courses from time to time to keep them abreast of the regulations. However following
natural/ quarrying hazards may occur during normal operation
Slope failure at the mine faces;
Accident due to explosives;
Accident due to heavy equipment/machinery;
Sabotage in case of magazine; and
