M/s. Dinesh Granite Exports is conscious of its environmental responsibility towards the

society in minimizing the pollution load due to this project and accordingly decided to carry

out the Environment Management Plan. The objective of preparing environment

management plan is to delineate effective measures to control and to mitigate the

environmental pollution. This report presents the environment management plan, detailing

the environmentally 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 semi-mechanized opencast mining method. Mining

will be carried out by forming benches of 6m height and 8m width. The Colour Granite in

the quarry lease applied area is exposed on the surface with boulders. 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 Q. L. area consists of mound of hillock which slopes in all the directions. The formation

is in the form of boulder and sheet of Charnockite Gneiss, which are of bluish in colour and

occupies most of the lease area. The maximum contour level is 210 m in the central part of

the Q.L area and the minimum contour 105 m in the southern part of the area. The relief is

therefore 105 m and slopes in Southern and western directions.

2.1 Regional Geology

In and around Srikakulam and Parlakimidi Blue and Brownish granite is extensively quarried.

It is a part of Eastern Ghat group of rocks consisting of Charnockite, Khondalite and

Granitoid a variety of hybrid rock formed by the interaction of Intrusive granite into the

Khondalite. The Eastern ghat group attains a maximum thickness in the Ganjam - Cuttack

tract. It occurs as ridges trending NE-SW. The eastern ghat belt exhibits high grade

metamorphism as evidenced by the presence of Garnet and Silliminite. The Charnockite

shows intrusive relation towards Khondalite and has itself under gone post migmatic

changes. Felspathic bands are common and are due to Granitisation.

2.2 Local Geology

The terrain in and around the area is of undulating in nature. The major portion of the area

is occupied by big boulders and sheet of Charnockite gneiss which consists of Quartz, Grey

feldspar, Silliminite and other Ferro Magnesium minerals like Hypersthenes, Hornblende,

Biotite and Garnet. The felsic and mafic bands alternate with each other to which imparts a

very good texture to the rock. The overall background of the rock is bluish. Two set of joints

are observed, one is parallel and the other perpendicular to strike direction. They are

widely spaced and are useful in splitting big blocks from the mother rock. The rock at places

is intruded by quartz vein and feldspar band. The weathering extends to a depth varying

from few inches to a foot in some areas. A megascopic and polished sample indicates that

the rock takes good polish and exhibits fine texture.

3.0 Exploration

a) Mining Carried out

Mining activity is under process in this mine lease area from the year 2003-2013 about

6671.814 m3 of granite blocks were produced.



4.0 Reserves

4.1 Estimation and Calculation of Geological Reserves

The reserves are estimated by cross sectional method. It consists of multiplying the sectional

area by the zone of influence which is the distance between the two cross sections. Based on

the information obtained from the mapping the area 'proved' category reserves may be

estimated from the top of the hill to a depth of 30 m, From the base of the proved zone, a 15

m depth is considered for the estimation of the reserves under the 'probable' category and

from the base of the probable zone, a 15 m depth is considered for the estimation of the

reserves under the 'possible' category. Section wise calculation of colour Granite reserves are

given in the table 1.3.

5.0 Mining

a) Type of Mining:

Opencast semi-mechanized method of mining deploying an excavator is proposed to be

undertaken in the area. The mining operation is proposed to be conducted in a very scientific

and systematic manner. The production will be carried out by forming benches of 6m height

and width will be kept more than the height i.e. about 8 m. The slope of the bench will be

maintained properly as per the stability of the strata and the overall slope angle of the pit will

be maintained not more than 30°.

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°.

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: gun powder.

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 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 SW side of the quarry lease applied area covering an area of

9600 m2 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.

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 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 6m 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

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.

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:

Mining operations should be carried out in the daytime, as during the night time the

sound intensity becomes higher;

The number of rows in a blast should not be more than four so that fly rock generation

and ground vibration is reduced.

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.

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 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 7 m BGL and the quarrying will be done on top of the hill

which is about 95 m above ground level. Maximum depth of quarry is about 15m from top of

hill, 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.

11.1 Water Resources

In this area water table is at greater depth of 7 m BGL and the workings are carried out on

top of the hill which is at 95m 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 11.1 KLD. Water sprinkling on mine haulage

roads etc shall consume 3.8 KLD. Wet drilling operations consume about 4.0 KLD. For green

belt development water consumption is about 0.9 KLD. Domestic purpose is about 2.4 KLD.

The water is to be sourced from nearby village through tankers. The generation of

wastewater from domestic sources is expected to be approximately 2.0 KLD, which will be

sent to septic tank followed by soak pit.

11.2 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.

11.3 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.

12.0 Waste Management plan

During this five years operations a total rock mass of 300000m3 will be excavated and 60000

m3 of granite blocks will be recoverable from this rock mass and remaining material of about

240000m3 will go as mineral waste. There is no overburden on the deposit. Boulders are

exposed on top of the colour granite.

13.0 Dump Area

The waste generated during plan period will be dumped in the SW side in the quarry lease

applied area covering an area of 9600 m2 with an average height of 30m. A retaining wall will

be constructed around the dump for preventing the slanting of boulders.

13.1 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.

13.1.1 Land Reclamation

After completion of mining works, worked out pits will be converted into water harvesting

structure. Hence, no reclamation proposals.

13.1.2 Soil Conservation Measures

The applied area is part of hill raising 95 m 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.

14.0 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.

15.0 Transport Systems

Nuguddi to Tekkali Village road is passing at a distance of 1.0 km in East direction. NH5 is

passing at 2.0 km in SE direction. Nearest town is Tekkali at a distance of 2.5 km in SE

direction. Tekkali railway station is at a distance of 3.0 km in SE direction. The finished

product and waste material is transported by road using trippers. The number of trips will be

approximately two per day for transportation of mineral and the tripper is covered with



tarpaulin. The lessee will deploy four tippers 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.

16.0 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.

Phased plantation will be taken up in this area. The plantation will also be taken up at in the

quarry lease area and within 7.5 m buffer zone over an extent of 5000m2. 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.

17.0 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 54. 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.

18.0 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

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;

Collection of the statistics of health of workers;

Monitor the progress of implementation of EMP.

19.1 Post Project Monitoring

The survey of post project monitoring comprises of the following monitoring aspects;

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 two stations,

one station within mine site and one station 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.

19.2 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 and Forests, New Delhi, State and Central Pollution Control Boards.

The Consent for Establishment, Consent for Operation will be displayed in a conspicuous

location for the information of the inspecting authorities of different departments.
