sound technology and the measures needed to contain and mitigate the anticipated

environmental impacts due to the project.



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.

2.0 Topography of the Area

The quarry lease applied area is a part of hill raising 40m above ground level within the

quarry lease applied area with topo relief in SE direction. The lowest contour is 160m and

highest contour is 200m in topo plan.

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.

Considering the recovery of the dimensional stones from the quarry is less than 20% and as

the boulders exposed from the bottom of the existing pits exhibit better quality when

compared to the excavated boulders, conservative estimation is made with 20% recovery.

Reserves Available for Mining

Total Geological Reserves

Proved Reserves = 427110 m3

Reserves Blocked under 7.5 Buffer Zone = 142770 m3

Reserves Blocked under Safety Slopes = 95030 m3

Total Reserves Blocked = 237800 m3

Reserves available for Exploitation = 189310 m3

Extraction of Market Grade Reserves @ 20% Recovery (Proved) = 37862 m3

Life of the Mine = 37862/1900.8= 19.91 or say 20 years.



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.



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°.

Total 26682 5336.4 21345.66.2 Drilling

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.



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



with an average of 5336.4m3 per annum.

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.



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



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



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.



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



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

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



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



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.



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



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



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

Accidents due to fly rocks and boulders.

In order to take care of above hazards/disasters, the following control shall be adopted:

All safety precautions and provisions of Metalliferous Mine regulation 1961 are strictly

followed during all mining operations;

Checking and regular maintenance of garland drains and earthen bunds to avoid any

inflow of surface water into mining area;

Entry of unauthorized persons shall be prohibited;

provisions;

Cleaning of mine faces shall be done regularly;

Handling of explosives, charging and blasting shall be carried out by competent persons

only;

Provision of magazine at safe place with fencing and necessary security arrangement;

Suppression of dust on the haulage roads by providing water sprinkling.

20.0 Environment Management Cell

A Cell for Environmental Management within Mine lease area at the project level, will take



the overall responsibility for co-ordination of the actions required for environmental

management and mitigation, and for monitoring the progress of the proposed management

plans and actions to be taken for the project. The Cell will be under the overall supervision of

the Mine Manager, and responsible for monitoring of the implementation of the various

actions which are to be executed by the agencies specified in the EMP. The Cell will be

headed by Mine Manager and the other members of the cell that will include a Horticulturist.

The EMC will prepare a formal report on environmental management and mitigation for the

Environmental issues at the Mine, at six-monthly intervals. Reports on any urgent or

significant issues may be prepared at shorter intervals. Apart from responsibilities listed

above, the EMC will have the responsibility of the following:

Collection of water and air samples within and outside the work zone;

Analyzing the water and air samples;

Implementation of the control and protective measures;

Land reclamation and vegetation;

Co-ordination of the environment related activities;

a. Ambient air quality survey

b. Noise Level Monitoring

c. Water quality monitoring

Ambient air quality and noise level Monitoring will be carried out at minimum four stations,

two stations within mine site and two stations nearby residential areas outside the mine.

Parameters like particulate matter, sulphur dioxide, oxides of nitrogen carbon monoxide and

lead will be monitored in case of ambient air quality. Water quality monitoring will be carried

out in the mine working area, sump and nearby village. The frequency of monitoring is

preferably once in three months on 24 hour basis. The samples will be collected in

accordance with the procedures given by CPCB.



20.2 Other Management Aspects

Records will be maintained for the analysis of ambient air quality, noise levels and water

quality. These records are not only required for the perusal of the Pollution Control Board

authorities to take preventive action against the environmental pollution. The management

will maintain the records as per the hazardous waste regulations and EPA regulations and

apply for the annual consents for air and water, and renewal of authorization for the storage

of hazardous waste as per the Hazardous Waste (Handling & Management) Rules, 1989. The

records of hazardous waste manifest will be maintained.

The mine will obtain the consent for establishment (CFE) and consent for operation (CFO)

from State Pollution Control Board as required under section 25/26 of the Water act, 1974

and under section 21/22 of Air Act, 1981, before commissioning and production as directed

by the Hon’ble Supreme Court of India. The CFO will be renewed each year by the

management in consultation with SPCB. The mine will submit environmental statement every

year before September 30. The management ensures that it will comply with all the

directions and regulations issued by the Ministry of Environment Forests and Climate change,

New Delhi, State and Central Pollution Control Board. The Consent for Establishment,

Consent for Operation will be displayed in a conspicuous location for the information of the

inspecting authorities of different departments.
