2.2 NEED FOR THE PROJECT

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

Clearance from Statutory Authorities.

2.3 TOPOGRAPHY

Topographically the area proposed for grant is a hillock with height of 105m gently

slopes towards SE direction, it is hilly area with minimum altitude of 552 and maximum

altitude 657m above M.S.L. and dendritic to sub dendritic drainage is observed. The area

is elevated towards North East of the hillock and sloping towards South West directions.

The area is devoid of any forest or tree cover. It comprises shrubs only.

There are no prominent natural drainage channels in the area. In general the area is plain

land.

2.4 GEOLOGY

Regional Geology: The Geological formations in the Chittoor District can broadly be

divided in to distinct and well marked groups and older group of Metamorphic rocks

belonging to Archean and Younger group of Sedimentary rocks belonging to the

Proterozoic age the later cover part of Gudipala block. The remaining parts of District is

occupied by Archean Rocks which consist of Schist, Gneisses, Quartz veins and basic

dykes. The Archean rocks have suffered considerable degree of tectonic disturbances, as

a result of which the rocks have been metamorphosed and recrystallized.




Stratigraphic Sequences established in the area is as follows:

Local Geology: The Subject area belongs to a hillock with a maximum height of 105m

gently sloping towards South East directions. The area is exposed with multi Colour

Granite Sheet Rock intruded with Quartz Veins & Dolerite dykes. This subject area is

exposed with sheet rock of pink colour granite which is locally named with branded rock

of “Multi Colour Granite” of Chittoor. Either side of the deposit area covered with

Granite Gneisses, it indicating it will be youngest suits of Granitic rocks. The peninsular

gneissic complex comprises gneisses (migmatitie), gray granite, and Pink Granite and

Gneissic granite. The gneiss in general show banding due to alteration of light coloured

quartzo- feldspathic minerals and dark coloured biotite or hornblende minerals. These

rocks may be separated in to two distinct groups namely the massive foliated types occur

as low dome shaped hillocks. The intrusive relationship of the granite rock is evident by

the presence of tongues and apophyges within the older rocks and the occurrence of

xenoliths of the older rocks within the granite.

years.

2.6 MINING

Type of Mining: The colour granite deposit is well exposed on the surface in view of this

the deposit will be worked by open cast method with semi Mechanized means of exploit

large blocks of colour granite. This will also help in improving the recovery percentage

of Dimensional blocks and reduce the waste. The applicant has sufficient machinery to

undertake semi Mechanized quarry operations. Open cast method of mining is carried out

in this mine by semi mechanization by using compressor operated jack hammer drills,

excavators, and dumper etc., Transportation will be made by trucks to dispatching point.

Bench height will be 6 meters and width of bench will be maintained 6 meters, slope of

the working pit will be 45o degrees under UPL. The following Quarry operations are

being conducted.

Removal / Excavation of O.B. and other Quarry Waste: There is a no overburden on

the deposit. Boulders are exposed on top of the Colour granite so that the removed

overburden is dumped in Dump yard. The SW side of 3586 sq.mts is selected for dump




yard for next five years and the waste will be stocked in the dump yard as earmarked in

plate No.5. Step dumping will be resorted. This material can be utilized to fill the pits

after quarry operations are over. When the dumps reach their optimum height suitable

greenery will be grown on these dumps to stabilize them.

Separation of large primary Blocks from the mother rock by pre-splitting

(Primary):

The mining will be followed in the form of linear cut method. This involves loosing of

the primary block from mother rock. Hence primary cutting will be done by line drilling

method where close spaced parallel holes along straight line will be made. Line drilling

method is used for separation of primary blocks.

i)Once the free face is developed in working place, the primary cuts are taken up over a

maximum length of 10mtrs to a width of 3mtrs and to a depth of 6mts depends upon the

joints availability. These dimensions are confirmed as for field studies. Primary block

will be cut into secondary blocks by Jackhammer drilling and wedge cutting and this

block will be dislodged from in-situ position by an excavator.

ii) Line drilling method will be used for cutting the primary blocks which involve

drilling and blasting.

iii) The holes are charged with low explosive cartridge like gun powder and non-delay

detonators for smooth blasting.

iv) The use of delay detonates causes fragmentation and cracks in rocks. The non

detonating cords are inserted into the holes and the holes are stemmed with muck and

plugged at the mouth and fired.

v) Thus the block will separate from the mother rock, which is pulled off from the face

with cranes or shovel.

Sub-Division of large Primary Blocks into Secondary Block:

i) Once the primary blocks are dislodged from sheet rock depending up on the

dislodged material secondary blocks are cut, fractures, block lines and penetrative cracks

are carefully trimmed and removed by this way.

ii) The commercial blocks will be trimmed so as that the sites form right angles to each

other.




iii) The applicant has been proposed to size of blocks could be formed from the ROM of

this property will be in the following direction ranges in Gang saw as well as cutter sizes.

Gang-saw sizes Cutter sizes

Length : 190 to 380 cm 90 to 180 cm

Width : 140 to 200 cm 60 to 90 cm

Height : 120 to 170 cm 40 to 70 cm

Production of Commercial Blocks:

Major boulders exposed are used for small size marketable blocks. After primary

separation the rock mass will be carefully examined to avoid hair line cracks, mineral

segregations 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 obtained good geometric shape of

granite. Thus the commercial blocks are produced.

Extent of Mechanization:

a. Since it has been decided to undertake semi-mechanized mining operations, the

following mentioned mine machinery will be deployed.

i) Excavator – Two (Bucket capacity 1m3, Boom length, 7m Model: Tata Hitachi 200 Lc)

ii) 450 CFM – AIR compressors – Two

iii) Jack Hammers – Six units

iv) 10 tones tippers – 2 Nos.

The lessee will be obtain quarry working permission from DGMS prior to start quarry

operation. The lessee will strictly implement the conditions issued by DGMS.

Magazine: Smooth blasting techniques and special explosives and silent non explosive

demolishing agents will be used. An area is demarcated within the lease are for portable

magazine. This site is located at a safe distance from the quarry, strictly adhering to the

rules and regulations laid down for safe storage and handling of the explosives as per the

explosives act. The applicant at the moment is not in possession of blasting license. He

will apply for a license as and when it required.

Drilling and Blasting: Drilling and Blasting plays vital role in determining the size and

shape of rough blocks. Drilling pattern is important in developing a working face and

also preparing the rough blocks suitable for their use in appropriate processing units.




Even though, there are no important places in and around the area, blasting will be

carried with all precautionary measures.

Drilling Parameters:

i. Drill holes diameter – 74/Pmm.

ii. Depth and inclination of the blast holes. 3 meter in case of separation primary

blocks depending on the block size. Then the drill-hole will be vertical.

iii. Spacing and burden: 1.5 x 3m.

iv. Stemming and charging of the blast hole. The Blast hole will be charged with 100

grams of explosives and filled with clan pills subsequently; the slot hole will be

stemmed.

v. Explosive type (1) Slurry based explosives or Gun Powder.

Board Blasting Parameter:

Drill-Hole patterns for primary and secondary smooth blasting. Uniform single line,

equidistant holes (line drilling) will be deployed for separation of blocks from mother

rock. In the case of sheet rock the primary drilling will be in the form of equidistant

vertical holes to take out blocks of Gang Saw.

Use of Minerals: Granite use for Monuments, Flooring slabs/tiles, Kitchen articles,

sculptures & for domestic use.

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 will be constructed in the area. The

roof will be 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 43 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 8218 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. 32.87 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

within the limits prescribed by A.P.P.C.B. The envisaged production of minerals is only

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

sprinkling through water tankers.

3.3 NOISE ENVIRONMENT

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

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

within a small zone around the mine. There is no major impact of the mining activity on

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

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 15-20 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 (15-20 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 6.0 KLD. Breakup

details are:

Sl. No: Purpose Quantity (KLD)

1 Dust suppression purpose 3.0

2 Domestic purpose 1.0

3 Greenbelt purpose 2.0

Total 6.0

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 along Eastern side of the quarry lease area (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 32872 m3/Year of waste will be generated from this mine Waste will be stocked in

the prescribed area in the SW side of the Q.L. applied area with an area of 2678m2 to a

height of 15 mts. During the first five years about 147558 m3 of waste material will be

generated.

Estimated Waste Quantity that will be generated over the entire period:

Total Colour Granite reserves = 1148577 m3

Colour Granite available in the format = 20%

Colour Granite reserves = 1148577 x 20% = 229715 m3

Total Mineral waste in the area = 80 %

= 1148577 x 80% = 918862 m3

3.5.2 Impact on Land use

The mine is located in an area of 4.000 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 patta

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.

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 8218 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 along Eastern side of the quarry lease area (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 32872 m3/Year of waste will be generated from this mine Waste will be stocked in

the prescribed area in the SW side of the Q.L. applied area with an area of 2678m2 to a

height of 15 mts. During the first five years about 147558 m3 of waste material will be

generated.

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: In every year about 30 mtrs. length of buffer zone will be planted

along the boundary on South East side of applied area. About 60 Saplings consisting of

Neem, Teak will be planted per year over an area of 30 m x 6m at 3m grid interval.

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 carry out 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.
