NEED FOR THE PROJECT

In order to meet the statutory requirements the lessee intends to obtain Environmental

Clearance from Statutory Authorities.

2.2 TOPOGRAPHY

The Q.L area consists of undulating terrain and comprise of hillocks and relatively flat

area of Khondalites, Charnockites and Lyptinites having a general trend in N-S direction.

The quarry lease is occupied by boulders and sheet rock formation in the Northern part of

the area and gradually slopes in the Southern direction. The maximum RL recorded in the

area is 60 m in the Northern part and the minimum RL is 53 m in the South Eastern part.

The relief of the area is hill is 7 m. Boulders and sheet rock of Khondalite Gneiss is

clearly exposed in the Northern part of the area. The drainage of the area is controlled by

a net work of streams which act as feeders to the tanks present in the vicinity of the area.

The tanks along with the bore wells and wells constitute the main source of water for

agricultural and drinking purpose. The water table is located at a depth of about 60-70 m

from the ground level. The region has a tropical humid climate with the maximum and

minimum temperature varying from 28-38 degrees in summer and 25-15 degrees in

winter. The average rainfall is around 900-1000 mm and the monsoon is from June to




September. The occupation of the people in of the region is agriculture. The drainage is

of dentritic pattern.

2.3 GEOLOGY

2.3.1 Regional Geology

The regional Geology is a part of Eastern Ghat Group of rocks consisting of Charnockite,

Khondalite and Granitoids, 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 magmata changes. Felspathic bands are common and are due to

Granitisation.

2.3.2 Local Geology

Surface Geological mapping of the area was conducted and litho units were marked of

the Geological plan which is enclosed as plate no – III. The applied Q.L area consists of

an undulating terrain and is located on the flank of a hill and is occupied of boulders and

sheet of Khondalite. The maximum RL is 60 m in the Northern part and the minimum RL

is 53 m in the South Eastern part of the, thus having a relief of about 7 m. Major portion

of the applied Quarry Lease area is occupied by boulders and sheet rock of colour

granite. 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 on physical examination is medium colour and grained, massive

and compact. The Colour varies from Yellowish to grey with Gneissic pattern. The

accessory minerals present are biotite and garnet. 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. Megascopic and polished sample indicates that the rock takes good

polish and exhibits fine good texture. The overall appearance of the rock is Greyish /

Yellowish in colour.

Litho units Present in the area: The main litho unit present in the area is Khondalite.

The mineral assemblages are Silliminite, Garnet, Quartz and Biotite.




EXPLORATION:

Already Carried Out: a) Preliminary study of the visual examination of granite texture.

b) Collection of surface sample and subjecting them to cutting and polishing

c) Study the marketability

Future Programme:

The deposit is not fully explored and hence it is proposed to carry out detail exploration

of the area, like opening a few trail pits, collection of more samples and subjecting them

to cutting and polishing.

2.4 GEOLOGICAL RESERVES

Based on the information from the mapping of the area, the 'proved' category reserves are

estimated to a depth of 20 m from the surface. From the base of the proved reserve, 10 m

depth is considered for the estimation of the reserves under the 'probable' category and 10

m zone below the probable zone is considered for estimation of reserve under the

'possible' category. The reserves are estimated by sectional method. It consists of

calculating the sectional area and multiplying it by zone of influence to arrive at the

volume. The reserves computed on the basis of the above consideration are given in table

below

The total reserves under the three category of proved, probable and possible is estimated

as 15,54,000 cu m and considering 20% recovery, the reserves of saleable blocks are

3,10,800 cu m and 12,33,600 cu m is considered as wastage. The reserves are likely to

change once the quarry is fully opened up. The reserves given here are estimated taking

in to consideration one homogenous mass there are every likely hood that the material

may be more defective than what is anticipated.

2.5.1 Mineable Reserves and Life of the Mine Mineable are calculated taking the Proved reserves only into consideration which are

7, 77,000 cu m. The reserve blocked in the mine safety benches and blocked in the buffer

zone is deducted from the proved reserves. The mine able reserves thus arrived are

presented below

S. No Description Quantity in cu m 1 In situ reserves under proved category 7,77,000 2 Reserves blocked in the 7.5 m buffer zone 76,250 3 Blocked in mine benches 38,850 4 Depleted Reserves Nil 5 Total blocked (2+3+4) 1,15,100 6 Balance reserves ( 1-5) 6,61,900 7 Recovery @ 20 % 1,32,380

Life of the Quarry: Considering the recoverable reserves as 1,32,380 cum and an

average production level of 8,400 cu m per annum, and the

Life of the mine is 1,32,380 cu m / 8,400 cu m = 15.75 cu m say 16 years.

2.5 MINING

In view of the shallow nature of the deposit, open cast semi mechanized method mining

method shall be adopted, by forming bench of 6m height.

Method of Quarrying:

Method of Quarrying: Semi –Mechanized quarrying method is to be followed involving the following

Machinery as mentioned in the table below

Table showing the Machinery to be deployed in the quarry

Machinery Quantity Nature of Work Excavator 3 no The excavator to be employed for the removal

of the over burden, small boulders and waste




rock Tipper 4 no For transportation of the overburden and blocksCompressors 6 no For drilling holes for splitting Jack hammers 18 For drilling holes Wire saw 2 Slotter 2 Generator 2 Jeep 1 Crane 20 ton For loading the blocks in to the trucks Derrick Crane 50 T For lifting blocks from the quarry floor

TOOLS: Drill Rods of size ranging from 2.5 feet to 10 feet long

Feather and wedges for splitting the holed rock in a linear direction

Grinding Wheels for grinding the diamond bits of the rods

Wire net, Wire rope, chain 50mm, and other spares

Wire saw

METHOD OF DELINEATION Several methods of delineation can be carried out and the prominent among them is

mentioned below.

Drilling and using Feather and Wedges: Wire saw will be deployed in the area to

separate the smaller chunk from the mother rock. Once the boulder is freed by removing

the soil and waste rock surrounding it, a series of holes are drilled by compressed air

using Jack Hammer at a regular interval of 15-30 cm depending on the size of the

boulder, the depth of the hole depends on the height of the boulder and the holes are

drilled up to the bottom leaving about a foot at the base. The holes have to be perfectly

straight and vertical so that the vertical split is obtained. Line drilling machine can be

used to drill straight holes. Feather and wedges are inserted into the holes and hammered

continuously applying uniform pressure and the boulder splits vertically. Similarly the

dressing is done and the boulder is given a rectangular shape. All the defects are avoided

during the dressing stage. Diamond Wire saw will be deployed for splitting the blocks

from the mother rock and splitting powder may be used for the splitting the big chunk

into smaller blocks of required dimensions.




Drilling :

Drill hole pattern will be uniform single lined pattern, equidistance holes from 0.33 mtrs

to 0.75 mtrs, 4.5 mtrs in depth.

Drilling Parameter

Drill hole diameter - 34.mm

Spacing depends upon the size of the boulder, in general it 15 cms from hole to hole for

better splitting.

Handling of the Blocks within the Quarry

Since the size of the boulder is big therefore it has to handled by a crane. The blocks will

be dressed at the pit mouth and after checking the quality they will be transported to the

stockyard. The waste will be loaded into the tippers and transported to the dump yard.

The size of the block produced from the quarry may vary 60-350 cm in length, 40-

200cms in width and 60 – 180cms in height. Hence a crane and 2 excavators are

sufficient to handle the blocks within the quarry.

Haulage & Transportation

Dressing of the blocks will be done at the pit mouth and are transported to stock yard by

the existing 2 tippers which are sufficient for handling the dressed blocks and for carrying

the waste to the dump yard. The dressed blocks will be transported to the various

destinations by hired trucks.

Dressing

The rough blocks of granite will be subjected to dressing at the pit mouth itself. Jack

hammers along with compressed air is used to drill holes at 15 cms interval will split the

block by using feather and wedges and applying uniform pressure by hammering on top

of the offsets. Then the blocks are brought into rectangular shape by hammer and chisel.

2.7 MINERAL PROCESSING

The Lessee intends to export and as well as sell the raw blocks for the processing units in

the country. The lessee does not possess a processing plant at the moment.




2.8 SITE SERVICES The rest shelter cum office, first aid room, and toilets are constructed in the flat portion of

the area. The roof is of asbestos sheets covered by hay to keep it cool in summer. A first

aid certificate holder will be the in charge of the first aid room. Protected drinking water

will be provided and stored in earthen pots.

2.9 EMPLOYMENT POTENTIAL

The mining activity will provide the job facilities to the local people. It will have 1 Mines

Manager, skilled & unskilled labour about 66 persons.




3. EVALUATION OF IMPACTS

3.1 INTRODUCTION

Opencast mining activity causes some adverse impacts on the surround environment

unless proper environmental management plan is adopted. Selecting suitable sites for

mining and adopting the guidelines prescribed by the Ministry of Environment & Forests

(MoEF) and Indian Bureau of Mines (IBM), one can minimize the major possible

impacts.

In this chapter, an attempt has been made to quantify the possible environmental impacts

on various features such as air, water, noise, land, ecology and socio-economies. The

following aspects have been studied to identify the possible impacts while achieving the

total production of 8,400 Cum/Year of Colour Granite .

The magnitude and significance of the environmental pollution caused by mining

depends on method of mining, scale and concentration of mining activity.

3.2 AIR ENVIRONMENT The impacts on air environment from a mining activity depend on various factors like

production capacity, machinery involved, operations and maintenance of various

equipments and vehicle. Apart from these, there will be other activities associated viz

transportation of mineral and waste, stocking facilities and dump management within the

mine lease area that may contribute to pollution.

3.2.1 SOURCES OF DUST EMISSION

Mining is carried out by open cast semi mechanized method by using jack hammer

drilling & wire saw cutting and using low explosive blasting. Based on the various

operations involved in the production of minerals, the various emission sources has been

identified as given below.




a. Point sources b. Area sources. c. Line sources. Drilling operations of the mine are considered as point sources. Extraction of mineral

from mine, are considered as area sources. Transportation of material from mining

benches to various end points are considered as line sources. The impact of above sources

on air environment is discussed below:

a) Drilling & Blasting One the boulder is freed by removing the soil and waste rock surrounding it, a series of

holes are drilled by compressed air using Jack Hammer at a regular interval of 15-30 cms

depending on the size of the boulder, the depth of the hole depends on the height of the

boulder and the holes are drilled up to the bottom leaving about a foot at the base. The

holes have to be perfectly straight and vertical so that the vertical split is obtained. Line

drilling machine can be used to drill straight holes. Feather and wedges are inserted into

the holes and hammered continuously applying uniform pressure and the boulder splits

vertically. Similarly dressing is done and the boulder is given a rectangular shape. All the

defects are avoided during the dressing stage. Diamond wire saw may also be employed

to dislodge the block from the parent rock.

Drill hole pattern will be uniform single lined pattern, equidistances holes from 0.33 m to

0.75 m , 4.5 m in depth. Spacing depends upon the size of the boulder, in general it 15

cms from hole to hole for better splitting.

The concentrations due to low explosives blasting will be confined to a maximum

distance of 10 m from the area of blasting. These concentrations will not be emitted

continuously. However presence of personnel near the blasting site during blasting will

be totally avoided. So, the impact of blasting on the air environment will be minimal.

b) Extraction & Loading

Extraction & Loading will be done by a crane and excavator and these activities of mine

operation is contributing to the area source emission and the extent of influence of this

operation is about 100 m2.




c) Haulage &Transportation In the operating mine, the dressed blocks from mine face to the consumers is transported

by hired trucks. The trucks will be well maintained so that exhaust smoke does not

contribute abnormal values of noxious gases and unburnt hydrocarbons. The other

sources of air pollution is due to the dust generated during the movement of tippers on the

haul road.

The above sources, which include drilling, low explosives blasting, excavation, haulage

for transport of blocks will contribute to dust pollution in the air.

3.2.2 ANTICIPATED IMPACTS The impacts envisaged due to mining activity are evaluated based on various factors. The

emission inventory of the pollutants is as follows, the main air pollutant would be dust or

particulate matter generated by handling and transportation of Colour Granite . But the

impact of mining operations on air quality is minimum as mining involved method by

using jackhammer drilling & wire saw cutting & low explosive blasting and as the

production quantity is very less i.e. 33.6 Cum/Day only.

3.2.2.1 Dust Generation and Control

The air pollutant would be dust or particulate matter generated by handling and

transportation of granite blocks. The existing ambient air quality at quarry lease area is 19

Cum/Day. The dust generated due to mining operations will be controlled by water

sprinkling through water tankers

3.3 NOISE ENVIRONMENT

Noise will be produced at the mine is due to operations of machinery, drilling, blasting,

and movement of vehicles. The noise generated by the mining activity is dissipated

within a small zone around the mine. The present noise levels at quarry lease area are

within the limits prescribed by A.P.P.C.B. There is no major impact of the mining

activity on the vicinity however; pronounced effect of above noise levels will felt only




near the active working area and on the personnel working in the vicinity. The impact of

noise on the villages is negligible as the villages are located far from the mine site.

3.4 WATER ENVIRONMENT The Mining activity will be carried out on mound slope will not have any effect on the

ground water and the static water table in this area is below 80 m.

3.4.1 Impact on Surface Water There are no major streams and rivers, which can get effected by the mining. Hence,

there will be no effect on the surface water.

During the present plan period quarrying will go to depth of 10 meters from the present

level of mining. During the monsoon period, the rainwater, if gets stagnated, will be

drained out. The benches will made with an inward slope to facilitate run off more faster

on to the mine floor. Small bunds, garlands and silting tanks also will be constructed to

minimize inflow muddy water which carry fine material.

3.4.2 Impact on Ground Water

Mining activity will be above the BWL (80 m). Hence, there will be no effect on the

ground water regime.

3.4.3 Impact on Water Quality

Water quality in the buffer zone have indicted that the ground water is free from heavy

metal concentration and this mining activity will not interference on the water quality.

3.4.4 Water Consumption & Wastewater Generation The water requirement for this proposed mining activity will be 10.0 KLD. Breakup

details are:

Sl. No: Purpose Quantity (KLD) 1 Dust suppression purpose 8.0 2 Domestic purpose 1.0 3 Greenbelt purpose 1.0 Total 10.0




There is no generation & discharge of wastewater from this mine. 3.5 LAND ENVIRONMENT Various components of land environment have been identified for study of impact of the

mine operations. Details of the same are given below:

3.5.1 Solid Waste Generation

Removal of weathered rock and the rock waste is the only solid waste that will be

generated from this mine. Some of the material from the waste may be sorted out and

used for making small blocks to be used by the local unit for making tiles. The market for

tiles is good at the moment and they will offer a better substitute for marble in terms of

price and quality. Some rejected and unsorted material may be used in the civil

engineering projects in the vicinity of the area. The waste material can also be crushed

into smaller sizes and can be used as road metal

The waste generated during the five years may be dumped in the zone separately reserved

for dumping in lease area (SouthEastern -Within the quarry lease area). The dump will be

designed in such that it will have slopes equal to the angle of repose of such material.

Garland drains have to be sunk along around the leading edge of the dump. A retaining

wall will be constructed around the dump to preventing the slanting of boulders Care will

be taken to minimize the waste generation at the source.

About 33,600 m3/Year of waste will be generated from this mine. During the five years

period the total quantity of waste likely to be generated is 1,68,000 cum. The waste

generated during the five years may be dumped in the zone separately reserved for

dumpling in the area. The dumps will have to design in such that it will have slopes equal

to the angle of repose of such material. Drains have to provided and the dump terraced.

Garland drains have to be sunk along around the leading edge of the dump. The dump is

located in the non mineralized south eastern part of the area covering over an extent of

7,000 sq m. The waste will be dumped to a height of about 30 m.




3.5.2 Impact on Land use

The mine is located in an area of 4.466 Ha. No forestland is involved.

After the operations cease, the mine spoiled area will be back field. It may not be

possible to complete regain the original topography of the area. During quarrying

whatever solid waste is generated shall be dumped at dumping site inside the Q.L. area.

The mining lease area is not a part of any type of forest. Entire mine lease area is govt.

land hence all the impact on land use is positive because aesthetic environment will not

be effected, as the mine is located on a plain with some bushes.

Due to opencast mining activities, the landscape will be slightly changed. There

will be no land subsidence as the country is made up of hard rock. The Soil cover in this

mine is almost nil and Agriculture is seen mainly in the plains in the vicinity of the lease

area and the mining will not have any impact on the agricultural pattern. Only few bushes

will be cleared to facilitate mining and other related activities and there are no big

trees, which may have to be cut.

3.5.3 Impact of Ground vibrations

Fragmentation of rock by blasting is an important operation in mining project, where hard

rock occurs. Blasting will be done only when it is absolutely necessary, using low

intensity explosives.

Blasting of the mineral at the proposed mine will be done by using Low-density

chemical explosives like ECM/ CaOH will be used. Sometimes smooth blasting may be

done using silent non-explosive demolishing agents like Acconex.

The ground vibrations caused by blasting will not have any affect as the mining is on a

mound and the vibrations will be minimum and will not be carried too far due to the hard

nature of the rock.

3.6 BIOLOGICAL ENVIRONMENT

There is no adverse impacts are anticipated due to the proposed mining activity on

biological environment. However, with the implementation of the environmental




management measures, there will be improvement in the parameters of biological

environment.

The tree species found with the core zone represent the common type of flora species

along with small shrubs and bushes. Due to mining activities community structure of the

vegetation will not change. Whereas diversity of plant species and food web index of the

area reduced to certain extent.

However, if the proposed reclamation of the mining area and dumped out area using

proper re-vegetation techniques and development of green belt around the ultimate limit

and roadside there shall be an improvement in the species diversity and food web index

compared to the existing level.

3.7 SOCIO- ECONOMIC ENVIRONMENT

3.7.1 No Rehabilitation The mine area does not cover any habitation. Hence the mining activity does not involve

any displacement of human settlement. No public buildings, places, monuments etc. exist

within the lease area or in the vicinity. The mining operations will not disturb/ relocate

any village or need resettlement. Thus no adverse impact is anticipated.

3.7.2 Improvement in Socio Economic Status It will be obvious to assume that the activities of the mining operations have to be

produced some improvements in the socio-economic levels in the study area.

The Lessee will provide employment to local population and it will give preference to the

local people whenever there is requirement of manpower.

The proposed mining activities will provide employment to persons of different skills and

trades. The local population is the largest plausibility among these employees. The

employment potential ameliorated economic conditions of these families directly and

provided employment to many other families indirectly who are involved in business and

service oriented activities. This in-turn will improve the socio-economic conditions of the

area.




3.7.3 Occupational Health and Safety

The mine is going to be developed mainly semi mechanized opencast method by using

jackhammer drilling & wire saw cutting & low explosive blasting. No major crushing or

pulverization will be done here. The small-scale mining will not have any ill effects on

the health of labour.

Excessive dust and noise are the chief health hazards for the miners. As already

mentioned these causative factors are well within the safety limits and the proponents

will strictly implement the prescribed safety measures. The health of the workers will be

regularly checked and suitable medical facilities should be created on or close to the site.

Highest safety will be ensured in the working conditions of the miners.




4. ENVIRONMENTAL MANAGEMENT PLAN

4.1 INTRODUCTION

The mining development in the study area needs to intertwined with judicious utilization

natural resources within the limits of permissible assimilative capacity. The assimilative

capacity of the study area is the maximum amount of pollution load that can be

discharged in the environment without affecting the designated use and is governed by

dilution, dispersion and removal due to natural physio-chemical and biological processes.

The Environmental Management Plan (EMP) is required to ensure sustainable

development in the study area.

This chapter covers the genesis of pollution, the principal sources of pollution, the nature

of pollution, the proposed measures required for meeting the prevailing statutory

requirements of gaseous emissions, wastewater discharge characteristics, noise levels etc.

for environmental management purpose in connection with the mining and mining related

activities in the study area.

This section discusses the management plan for mitigation/abatement impacts and

enhancement of beneficial impacts due to mining. The Environmental Management Plan

(EMP) has been designed within the framework of various Indian legislative and

regulatory requirements on environmental and socio-economic aspects.

Environmental Management Plan giving the environmental protection measures at mine

to meet the stipulated norms of IBM/MoEF are as detailed.

4.2 AIR POLLUTION CONTROL MEASURES

The present ambient air quality measurements in the mine area are well within the limits.

Due to the proposed production of 8,400 Cum /Year of Colour Granite , there will be

marginal increase in dust concentrations.




Mitigative measures suggested for air pollution control are based on the baseline ambient

air quality monitoring data. From the point of view of maintenance of an acceptable

ambient air quality in the region, it is desirable that air quality should be monitored on a

regular basis to check it vis-à-vis the standards prescribed by CPCB and in cases of non-

compliance appropriate mitigative measures shall be adopted.

The following dust prone areas are identified for adopting proper control measures in the

mine area.

i) Drilling & Wire Saw Cutting & Blasting

ii) Excavation

iii) Transportation

The environmental control measures which will be implemented to control the fugitive

dust released from the proposed production are given below:

Wet drilling system & Dust proof

Optima Wire Saw Cutting (using water reduces dust)

Use of sharp drill bits for drilling holes. The charge concentration of the

explosives will be between 10 – 40 grams per linear meter.

Water sprinkling arrangements such as specially fabricated tankers mounted on

tipper are deployed at mine site to control the fugitive dust generation from the

haulage roads.

Regular grading of haul roads and service roads to clear accumulation of loose

material

The blasted blocks (temporary) are wetted by spraying water

Avoiding blasting during high windy periods, night times and temperature

inversion periods.

Excavation operations are suspended during periods of very strong winds.

Massive afforestation for control of dust

Spraying of water on sub grade stacks




The vehicles and machinery are kept in well-maintained condition so that

emission of fugitive constituents is minimized.

Plantation of wide leaf trees, creepers, tall grass around working pit, along roads

will help suppress dust.

Tall trees with an average height of 5 m will be developed all along the boundary

of the lease area to minimize the dispersion of the dust from the mining.

Periodical monitoring of air quality to take steps to control the pollutants.

4.2.1 OCCUPATIONAL HEALTH & SAFETY MEASURES

All the precautions would be adopted to prevent dust generation at site and to be

dispersed into the outer environment. However, for the safety of workers at site, engaged

at strategic locations/dust generation points like drilling, loading and unloading points,

etc., dust masks would be provided. Dust masks would prevent inhalation of RSPM

thereby reducing the risk of lung diseases and other respiratory disorders. Regular health

monitoring of workers will be carried out.

4.3 NOISE POLLUTION CONTROL MEASURES

The ambient noise level monitoring is carried out in and around the proposed mine shows

that ambient noise levels are well within the stipulated limits of CPCB.

Noise generation may be for an instant, intermittent or for continuous periods, with low

to high decibels. Periodic inspection and checks of the risk prone areas and equipments

have to be conducted.

To control noise pollution during the proposed mining operations following steps will be

practiced.

The noise generated by the machinery will be reduced by proper lubrication of the

machinery and equipment.

The workers employed should be provided with personal hearing protection

equipment, with earmuffs and earplugs combined, as a protection from the high

noise level generated at the plant site.




The provision of green barrier along the boundary will further reduce the

propagation of noise level generated.

Limiting time exposure of workers to excessive noise.

Speed of trucks entering or leaving the mine is limited to moderate speed of 25

kmph to prevent undue noise from empty tippers.

Safety in Blasting

Care should be taken to evacuate the mining area completely at the time of low explosive

blasting operations. The blasting team should be equipped with all personal safety and

precautionary measure. The following safety measures will be given attention while

conducting the blasting operations.

A blasting SIREN should be used at the time of blasting for audio signal.

Before blasting and after blasting, red & green flags should be displayed as visual

signals.

Warning notice boards indicating the time of blasting and NOT TO TRESPASS

are displayed prominently.

4.4 WATER POLLUTION CONTROL MEASURES

The action program for minimizing adverse affects on water regime is to prevent wash-

off of mine water and uncontrolled run-off water during monsoon. Proposed measures for

this are as follows:

a) Building/extending of retention/toe walls at the foot of the dumps

b) Construction of Garland drains along the slopes to divert the rainwater course

away from the dumping areas.

c) Covering of dump slopes with grass plantation to stabilize and prevent erosion.

d) Plantation of trees along the ridges and slopes.




4.5 LAND ENVIRONMENT

The Dhanbad declaration on Environmental Management in Mining Industry states “It is

imperative that in order to ensure the continued and sustained progress of the mining

industry in India, the environmental dimensions should be integrated into the planning,

design, development, operation and working practices of quarry on scientific and rational

lines, by the Governments and the industry in a mutually reinforcing manner”. The land

related Environmental Management Plan (EMP) has been presented here under two

sections viz., Soil & Water conservation and Afforestation.

Storage and Reuse of Top Soil:

Topsoil removed during clearing of the area for granite extraction shall be stacked

separately to check the erosion of the stacked soil. A retaining wall shall be constructed

all around the topsoil stockyard. Planting of grass and local species etc., are proposed on

the surface of this stack to prevent erosion and to increase the soil nitrogen. As per the

analysis of the soil samples they are found to be basic in nature. During afforestation, it is

recommended to plant fast growing species with good canopy cover and dense leaf

density and some ornamental species to give a good aesthetic look. It is recommended to

sow neem, mahogany plants as soil and climatic conditions are suitable for the growth of

these plants.

Solid Waste Management Removal of weathered rock and the rock waste is the only solid waste that will be

generated from this mine. Some of the material from the waste may be sorted out and

used for making small blocks to be used by the local unit for making tiles. The market for

tiles is good at the moment and they will offer a better substitute for marble in terms of

price and quality. Some rejected and unsorted material may be used in the civil

engineering projects in the vicinity of the area. The waste material can also be crushed

into smaller sizes and can be used as road metal

The waste generated during the five years may be dumped in the zone separately reserved

for dumping in lease area (SouthEastern -Within the quarry lease area). The dump will be

designed in such that it will have slopes equal to the angle of repose of such material.




Garland drains have to be sunk along around the leading edge of the dump. A retaining

wall will be constructed around the dump to preventing the slanting of boulders Care will

be taken to minimize the waste generation at the source.

About 33,600 m3/Year of waste will be generated from this mine. During the five years

period the total quantity of waste likely to be generated is 1,68,000 cum. The waste

generated during the five years may be dumped in the zone separately reserved for

dumpling in the area. The dumps will have to design in such that it will have slopes equal

to the angle of repose of such material. Drains have to provided and the dump terraced.

Garland drains have to be sunk along around the leading edge of the dump. The dump is

located in the non mineralized south eastern part of the area covering over an extent of

7,000 sq m. The waste will be dumped to a height of about 30 m.

Stabilization and vegetation of dumps:

The dumps will be stabilized and shaped trapezoidally. The angle of repose will be in

such a manner that the run off of material will be avoided. The trench will be dug around

the dump to avoid run off. The dumps will be safe-guarded by plantation of trees along

the slope and of the soil cover area. In first five years, it is planned to undertake

plantation of 50 trees per year on the slope of the dump, depending on facilities available.

Land Restoration/Reclamation:

Land restoration or reclamation of the area is very essential in any mining industry.

Proper measures adopted during restoration will control most of the adverse

environmental impacts of Quarry and also improve the aesthetic beauty of the area. Due

to the Quarry activities in this area the profile of the ground will change due to formation

of pits. At the end of the Quarry operations, the top soil/mineral rejects will be utilized

for back filling wherever suitable and rehabilitated.

Following steps shall be taken for improving and protecting the environment.

a) Quarry lease area

b) Surrounding the Quarry lease area.

c) Surrounding the statutory buildings

d) On the undisturbed virgin lease area.




Surrounding the Mining area

The dust generated during the quarrying operations will be carried by wind and will be

deposited over the trees and on the adjacent area around the quarry in the buffer zone. To

filter this dust, a green belt of 10m width shall be developed along the quarry lease area

i.e., around ultimate pit limit, this green belt will also act as sound barrier. In between the

tree saplings, grass and bushes shall be grown. Creation of the green belt around the lease

areas shall be undertaken on priority basis and shall be completed concurrent to Quarry

over a 10-year period.

Surrounding the statutory buildings

All around the proposed statutory buildings and along the road sides trees shall be planted

in addition to the existing ones which will protect the workers from the noise and dust.

To plant trees around the statutory buildings, the topsoil that is going to be mined from

the area shall be laid to form a strip of 10-15m width and 0.5m thickness.

On the undisturbed virgin lease area:

The undisturbed virgin lease area shall be utilized for afforestation purposes by

developing the area with local varieties. This work shall be done after the cessation of

Quarry operations.

Afforestation Plan:

Each year some part of the barrier zone will be subjected to afforestation and care will be

taken to protect the sapling. Suitable species will be planted in consultation with the local

authorities and forest department. The table below shows tentative afforestation plan for

the plan period.

Apart from the green belts and aesthetic plantation for eliminating fugitive emissions and

noise control, all other massive plantation efforts shall be decided and executed with the

assistance and co-operation of the local community. Based on the community needs the

afforestation would mainly aim at:

a) Protection & Development of Natural Vegetation

b) Protection of soil erosion

c) Plantations of fuel wood blocks to meet the energy requirements.

4.6 SOCIO ECONOMIC BENEFITS

There is positive impact on socio-economics of people living in the villages. The villages

in buffer zone depend upon agriculture. Mining operations in the subject area has positive

impact by providing direct and indirect job opportunities. There will be indirect

employment opportunities in transportation of ore to destination.

4.7 POST PROJECT MONITORING

The Lessee will monitor the environmental parameters as per APPCB/IBM/CPCB

guidelines

4.8 IMPLEMENTATION OF EMP & MONITORING PROGRAMME

The environment management plan is detailed on the basis of impact assessment. Control

and mitigation measures for the adverse impacts envisaged. As the major environmental

attributes have been confined to the project area alone, implementations of the proposed

control measures and monitoring thereof will be undertaken on the regional basis. The

Lessee will ensure the implementation of the measures within the mine area and carryout

efficient monitoring. In order to implement the measures suggested for mitigating the

adverse impacts on the environment, it is suggested to monitor the environmental

parameters regularly.

The details of investments to carryout the regular monitoring and pollution control

measures are given below in table – 2.

CONCLUSIONS, SUGGESTIONS/RECOMMENDATIONS

The Mining method proposed as per the approved Mining Plan from Dept. of Mines &

Geology is small-scale semi mechanical mining activities without deployment of deep

hole drilling and use of Heavy machinery. The actual method of mining Colour Granite is

by slicing. Based on the appraisal of the existing environmental scenario coupled with

the assessment studies carried out, it is concluded that there is no long term

environmental impact due to the Colour Granite quarry at the lease area.

The particulate matter getting airborne from the mining activity gets dispersed in close

proximity itself and settles down early. The noise levels due to the proposed quarry

activity are also not of a higher order that calls for immediate corrective measures. The

ground water analysis indicates that the sources do not get influx of pollutants from the

quarry activity. There is positive socio-economic front in the surrounding region due to

the proposed mining industry. The practice of afforestation scheme is a step in the right

direction towards achieving ecological balance.

Suggestions/Recommendations

Even though there is no perceptible impact from the quarry activity on the environment of

the region, it is imperative that mitigative measures have got to be implemented on full

scale for creating environmental balance and intern maintain the ecology of the region.

The following suggestions/recommendations merit due consideration in this regard.

As no control over wind can be exercised, the frequency of the dust suppression measures like constant watering of the haul roads shall be practiced.

Afforestation as envisaged in the mining plan is to be carried out so that it not only enhances the green canopy but also stop the spread of dust particles and air borne pollutants.

Surface water conservation measures and groundwater recharge be given high priority.
