4. REASON FOR ENVIRONMENTAL IMPACT ASSESSMENT (EIA)

The impact of mine on the environment depends to a large extent on its location with

respect to Human settlements, meteorological conditions, ambient air quality, water

bodies, agricultural and forest land etc.

Most of the adverse impacts of mines are amenable to technological control by

providing necessary preventive and control measures and finally through effective

environmental management of the operating mines. Keeping in view the likely impacts

of mines on environment, this Rapid environment impact assessment report has been

prepared for submission to State Pollution Control Board and Ministry for Environment

and Forests (MoEF) for clearance of the proposed mining area.

5.2 Mining Method

Presently mining activity has been closed for obtaining of Environmental clearance

from SEIAA. Existing mining is being carried out by the open cast manual method of

mining using hand tools such as spades, chisel, hammer etc. Lumps of mineral are

being transported from pit bottom to surface manually by head load using tasla and

the earlier waste was in the form weathered ferruginous material is being kept in






lease area and regular use of explosive is being done in the area. From the loading

point of view, mineral is transported by truck/dumper to user industries. Loading

of mineral in to truck dumper is being done manually. Blasting has been done for

having purpose in ore body. Presently total excavated area is 5.464hect. There are

38 quarries in the ML area. The ultimate depth of excavated pit is varies from 6m to

20m. Details of existing pits excavated within the applied area are given as follows:

Proposed mining operations such as development, drilling, winging of ore, loading

and transport etc. will be carried out by opencast other than fully mechanized

method of mining using JCB, excavator cum loader shovel, Loader etc. loading of

mineral/waste in to truck/ dumper will be done by excavator cum loader.

Opencast method of mining (A category other than fully mechanized mines) has

been proposed. All operations of mining will be been done by deployment of heavy

earth moving machineries for excavation, loading & transport. Regular drilling will

be done for heaving purpose in the lease area. Blasting will be done on regular

basis. Random holes of 2.8m depth/deep hole drilling will be done. Haul road has

been extended to every working bench and to the floor of the quarry.






As per earlier approved SOM first five year of SOM period has been ending by the

31st March 2013 and the required modification is proposed of its left period i.e.

2011-12 to 2012-13 under the category of mining from B to A category (OTFM).The

mining operations are proposed northern and north western part of the existing pit

Q-I.

Reasons for choosing the work site are:

As the area is unscientifically haphazardly developed hence to merge all pits in one

pit the proposal are given at two place i.e. eastern side and western side.

Lay out of haulage road: Haulage roads 5-6m wide will be a maintained and

developed at required places, it will be laid at maximum 1: 16 gradient from surface

stack yard RL of 455to pit bottom at 440mrl with in bye roads to faces of individual

benches.

Benches in Limestone: As per geological finding there will be one production

bench of 4-5m height. (However if required sub benching will be done to facilitate

jackhammer drilling & blasting) Width of benches will be as per DGMS

requirements/ not less than height where as dolomite bench length will be as per

proposal given five year production table. The ROM quantity of Dolomite from

individual bench will be 100%.

Dolomite & Limestone: 100% recovery

OB: Nil

Mining losses; 5% unrecoverable

Proposed mining is suggested lateral and depth wise, in keeping view of systematic

development of benches and providing the proper shape.

Year 2011-12

During this year about 18900m2 in west and 21250m2 are in east will be

developed with one production bench of 4m height in dolomite and simultaneously

the limestone band of 2m thick will be exploited from the western block. Thus

western side average RL will be reached from 463- 459m while eastern side

average RL will reach from 451-455m.

Total production: Dolomite =Limestone 360776 MT & Grade: SMS/BF/CEMENT






Year 2012-13

During this year about 18900m2 towards southern direction will be developed in

continuation of previous year excavation of western block and similarly 24640m2

will be in eastern block with one production bench of 4-5m height in dolomite. Thus

western side average RL will be reached from 460- 455m while eastern side

average RL will reach from 451-455m.

Total production: Dolomite =Limestone 360776 MT & Grade: SMS/BF/CEMENT

Total development at a glance

During the ensuing two years development 8.69 ha area will be develop with

average 5m depth. In ensuing period dewatering will be required during the post

mansson season which will be done by the 5HP pump and drain to the nallah in

northern side. During the period of mining scheme mine office and site office with

all facilities viz. separate toilet for male and female will be maintained as earlier.

7. IDENTIFICATION OF IMPACT

The following parameters are most commonly affected by mining activities:

§ Topography

§ Drainage

§ Flora

§ Fauna

§ Air quality

§ Surface and ground water quality

§ Noise levels

§ Land use

§ Socio-economic conditions

TOPOGRAPHY

Topographically the majority of the area has medium relief undulating topography

while the southern part has sharp gradient, the highest elevation is of 485m in the

southerly side hillock direction and the lowest one is 440 in the north east, thus the

total elevation difference is of 45m. The southern part is covered by scattered

plantation. The gradient is toward the northeast direction is steeper in the

southwest direction.

§ Peripheral sides with slopes adequately stabilized by manual and biological

means.






§ Partly excavated area will be backfilled and afforested

AMBIENT AIR QUALITY

All mineral processing operations including surface mining, crushing, screening,

material handling and transfer operations are potential sources of particulate

emissions. These sources may be categorized as either process sources or fugitive

dust sources. Process sources include those sources for which emissions are

amenable to capture and subsequent control. Fugitive dust sources generally

involve the re-entrainment or settled dust by wind or machine movement. Factors

effecting emissions from either source category include the type, quantity and the

moisture content of the rock processed, the type of equipment and operating

practices employed as well as topographical and climatic factors. Ambient air

quality monitoring data reflects that the “PM10” is major pollutant of the area while

SO2, NOx, CO levels are within the limit. The various activities/factors which

contribute to high SPM level in the area are:

1. Mining Activity

• Drilling and blasting operation Loading and unloading of excavated material

• Haulage of material over roads

2. Emission rate due to mining activity

The main source of air pollutant in mine is particulate. The emissions of sulphur

dioxide, Oxides of Nitrogen (Nox), are marginal and are contributed by vehicles

plying on the haul roads. A short-term model computes maximum ground level

concentration (MGLC) due to mining activity and distance from source as a

function of wind speed and stability class. The Pasquill atmospheric stability

classes categorized the atmospheric turbulence into six stability classes named

A, B, C, D, E and F with class A being the most unstable or most turbulent class,

and class F the most stable or least turbulent class.

The Pasquill stability classes Stability class Definition Stability class Definition

A very unstable D neutral B Unstable E slightly stable C slightly unstable F stable






Meteorological conditions that define the Pasquill stability classes

Note: Class D applies to heavily overcast skies, at any wind speed day or night Mixing Height

As the site specific mixing heights are not available, USEPA approved general mixing

heights as applicable for industrial source complex (ISC) model have been

considered for modeling to establish the worst case scenario. The mixing height

considered for modeling is given in the Table:

Stability Class Mixing Height (m) A 1300 B & C 900 D 750 E & F 400

Based on the AP-42 manual (compilation of air pollutant emission factors volume 1;

stationary point and area sources, fifth edition, 1995) published by USEPA wherein

the emission factors of different pollutants from various activities/processes are

compiled. In the active mining area the major activities are excavation and loading.

The emission factors for these activities are given in AP-42 are converted to g/s. For

active mining 3.5 x 10-2 lb/ton or 1.59x10-2 kg/ton are considered as mentioned in

AP-42 manual. The emission rates for the proposed mining are given below:

Mining Activity Emission Factor Proposed Mining (tones /day)

Proposed emission rate (g/s)

Dolomite 3.5x10-2 lb/ton or 1.59x10-2 kg/ton of production

1167 0.64






4. Emission calculation due to transportation During transportation of mined ore by heavy vehicles like trailors, trucks,

dumpers, fugitive dust emission occur due to movement of heavy vehicles on

earthern roads. The quantity of emissions depends on various aspects like

climatic conditions, moisture in the soil, speed of the vehicle, frequency of the

vehicles etc. Generally such emissions can be controlled to a great extent by

spraying water on these roads intermittently. Emission calculation due to

transportation of ROM & mineral is as follows.

The mining operations are planned by JCB for the removal of overburden. Drilling

of the blast holes is proposed to be done by the compressed air feeded jack

hammers and wagon drill. Mineral Loading will be done manually. Targeted

production of Dolomite is 500000t per annum. (Taking avg bulk density is 2.65 for

soil/waste/OB/mineral). No. of working days is 300days. So far optimum

production is 1667t per day.

Excavation and loading

Loading operation at face will be done by excavator’s hydraulic shovels of 1.00

cu.m bucket capacity is proposed to be used for excavation and loading of total

volume in m3.

The excavator will be kept at 900 to production face, after getting dozing; the

heaving will be done by hydraulic shovels of 1.00 cu.m bucket at 900 swings to

truck or dumpers. The boom height will be higher than truck/dumper height.

While operation proper safety will be taken care by whistling and keep the person

away at safer distance from excavator while it is in operation.

Total HC emissions from one truck = 0.6 g/bhp-hr x 73.1 bhp.

= 438.6 g/hr. = 0.012 g/sec.






HC emission due to total trucks = 7x 0.012 g/sec.

= 0.084 g/ sec.

NO2 emissions:

NO2 emission for vehicle type –F = 6.9 g/bhp-hr.


Total NO2 emissions from one truck = 6.9 g/bhp-hr x 73.1 bhp.

= 504.4 g/hr. = 0.14 g/sec.

NO2 emission due to total trucks = 7 x 0.14 g/sec.

= 0.98g/ sec.

Drilling will be done using compressed air feeded jack hammers and wagon drill

with wet drilling and muffle blasting operations will be there. However, some

extent of background concentration of PM10 may be attributed due to the

proposed mining activity in the same mining lease area. The results of the

background PM10 concentration at all receptors over the area are insignificant and

are very low as compared to the standards prescribed by the CPCB for ambient air

quality. Thus, it can be safely stated that due to the proposed mining activity,

there will be no adverse impact on the existing ambient air quality. Following air

pollution control measures shall be taken to minimize negative impact due to

mining activity:

• Dust suppression over the roads by using proper water sprinkling.

• Proper stabilization of topsoil by adopting proper plantation / effective

means.

• Green belt development along the roads, over the overburden dumps and in

the mining area as whole.

• Proper maintenance of haulage roads, which shall be used for transportation

of material

Ø Emission due to crusher

• Emission during crushing operation

During crushing operation, generation of particulate emissions is inherent

and the emissions are most apparent at crusher feed and discharge points.






The greater the reduction in size during subsequent crushing stages from

primary, secondary to tertiary crushing, the higher the emissions.

Primary jaw crushers produce more dust than comparable gyratory

crushers because of the bellows effect of jaw and because gyratory

crushers are usually choke-fed, thus minimising the open spaces from which

dust may be emitted. For subsequent reduction stages, cone or roller type

crushers produce more fines as a result of attrition and consequently

generate more dust.

• Emissions During screening

In the screening section, the mixture of dolomite is classified and separated

according to size. Generally the screening efficiency is considered to be in

the range of 60 to 75%. The screening equipments commonly used include

grizzlies, shaking screens, vibrating screens and revolving screens.

Although screening may be performed wet or dry, dry screening is the

most common. Dust is emitted from screening operations as a result of the

agitation of dry stone. The screening of fines produces higher emissions than

the screening of coarse sizes. Also screens agitated at large amplitudes

and high frequency emit more dust than those operated at small

amplitudes and low frequencies.

• Emissions During material handling

In the material handling section, various handling devices like feeders, belt

conveyors, bucket elevators and screw conveyors are used to transport

crushed materials from one point to another. Particulates may be emitted

from any of the material handling operations. Most of the emissions

occur at transfer points. Since transport of material on the conveyor causes

little disturbance of air and emissions that occur due to the wind are judged

to be minimum. The transfer points include transfers from a conveyor on to

another, into a hopper and on to a storage pile. The amount of uncontrolled

emissions depends on the size distribution of the material handled, the belt

speed and the free fall distance.

• Nature and Spread of Emissions






The dust is generated primarily due to size reduction and handling of the

dolomite at various stages. The major source of dust generation is during

size reduction in the primary, secondary & tertiary crushers. The fines in the

dust generated increases with subsequent stages of crushing i.e., more fines

are generated in secondary crusher as compared to primary crusher. The

dust is also generated during handling of stones, especially at the point

where the stones fall through a height from places like one belt to another or

from belt to hopper or stock piles etc. During vibratory screen large quantity

of fine dust is emitted.

Coarser part of the dust settles down within the premises but the finer

particles get air borne and get carried away with wind to longer distances.

The actual area of the source of the dust generation is quite small (about 0.5

to 1 square meter)at each source, but as the dust rises it spreads and

typically the area in which it spreads is more than 10 –15 times larger than

the area of actual emissions at about 3 to 4 meters height. This rising dust

column shifts from left to right or north to south etc. depending on wind

direction and current and eventually it gives an appearance that the dust is

emitted from almost every inch of area in the stone crusher.

• Factors that Influence Emissions

Factors affecting emissions that are common to most operations include

moisture content in the rock, type of rock processed, type of equipment, and

operating practices employed. These factors apply to both process (primary)

sources and fugitive (secondary) sources in quarry and plant operations.

Depending on geographic and climatic conditions, the inherent moisture

content or wetness of quarried rock may range from nearly zero percent to

several percent. The effect of moisture content is especially important during

quarrying, material handling, and initial plant operations such as primary

crushing. Surface wetness causes fine particles to agglomerate or adhere to

the faces of larger stones, resulting in a dust suppression effect. However, as






new fine particles are created by crushing and attrition and since moisture

content is reduced by evaporation, this suppressive effect diminishes in later

stages.

The type of rock processed is also important. Soft rock produces a higher

percentage of fines than do hard rock’s because they are more friable.

Therefore, processing of soft rocks has greater potential for emissions.

The type of equipment and operating practices employed also affect

uncontrolled emissions. Equipment selection is based on a variety of

parameters, including quarry characteristics; rock type processed, and

desired end products. Emissions from process equipment such as crushers,

screens and conveyors are generally a function of the size distribution of the

material, and the amount of mechanically induced velocity imparted to it.

Water Resources

Make-up of water

There are two sources of mine water accumulation (1) Rain water (2) Ground water

seepage. As indicated in base line information, the seepage is observed from the

face of mine at a depth of 20m. Only rain water is the main source of mine water.

The rain water accumulation is estimated as under:

Q = A (0.85 P – 30.5) x 0.22

Where: Q is quantity of rain water accumulation (in lac gallons)

A is area receiving the rainfall (Ha.)

P is rainfall in cm.

A = Excavated area of mine pit + area of reservoir

= 0.0 + 2.0 = 2.0 Ha.

P = 116cm (average for five years)

Therefore Q =29.96lac gallons






The estimated quantity of water consumed annually is 29.96lac gallons; therefore

mine seepage would be nil. The annual ground water seepage is quite low; hence, no

adverse impact is expected on ground water regime.

Water Quality

There is no discharge of effluent from the mine. Sump water analysis indicates that

it is reasonably clean without any harmful ingredients and can therefore be used for

agricultural purposes. The plantation proposed to be raised around the mine will

largely depend for their survival and contribution from a part of the mine

discharged water. Discharge from septic tank at mine site will be much limited for a

meager strength of less than 100 personnel. Hence, no deterioration of ground

water or surface water is anticipated. The quality of mine water will lie well within

the General standards for inland surface water. No impact on existing surface water

resources is expected on the mining activity is confined to limited area. In fact, the

accumulated rain water in the quarry pits will recharge the ground water of the area

Noise Level

There are a number of sources from which high noise level is generated, some

continuously and some intermittently. Intermittent noise is also generated during

un-loading and loading operations.

Ambient Noise level monitoring in and around core zone of the mining lease area

reflects that at locations near to mining activity/roads, noise levels are within the

standards prescribed. The working environment in the mines satisfies the

standards prescribed by OSHA. The prevailing day and Night noise levels around

the Village reported are between 38.32-46.72 dBA and 35.65-36.75dBA

respectively which are occasionally high due to traffic movement.

Noise Generating due to Blasting

Noise generated from blasting is neither continuous nor for a shorter duration but

instantaneous. It takes less than 5 seconds to occur. Noise of blast is site specific

and depends on type, quantity of explosives, dimensions of drill holes, degree of

compaction of explosive in the hole and rock. Typical noise levels generated by

blasting from the mine lease are presented in Table.






Typical Noise Generating Source

Total Explosive Charge Distance (m) from Blasting Site Noise Level (dB)

145 300 125-130 240 300 120-125 500 300 115-120

The noise levels during blasting operations are likely to be in the range of 110-130

dB(A) at 300 m distance from the blast site. The noise levels tend to decrease with

distance. As the blasting is likely to last for 5 to 7 minutes depending on the charge,

the noise levels over this time would be instantaneous and short in duration. As the

nearest village is located at about 1.5 km from the mine center, impact due noise

levels from blasting is not envisaged.

Noise Generated due to Drilling

The drilling operations in the existing mine as well as in the mines are carried out

by compressed air feeded jack hammers and wagon drill with wet drilling. The

typical Noise levels due to drilling at 1-m distance will be about 85 to 95 dB(A). It is

noted that the noise levels due to drilling are above 90 dB(A). Noise generated due

to drilling may affect workers if equivalent 8-hr exposure is more than the safety

limit of 90 dB(A).

Noise Generated due to Excavation and Transportation

Typical noise levels generated during excavation, loading and transportation

activities of the mining activities are presented in Table.

Typical Noise Generation Due to Excavation/ Loading/ Transportation

Sr. No. Name of the Equipment Noise at Source dB(A) 1 compressed air feeded jack hammers and

wagon drill with wet drilling 85-90

2 Excavator /loader 90-95 3 Tippers 80-85

The total noise from all of the above equipments occurs only when all the

equipments operate together and simultaneously, which is a remote possibility.

Noise Dispersion from the Mine






The noise generation from the mine will be from various sources, which will be

originating from various locations within the quarry pit. For the purpose of noise

dispersion, it is assumed that all the noise generating sources from the quarry as

one source. Hence, total noise from drilling, excavation, transportation and loading

will be equivalent to 107.5 dB(A). The dispersion of this noise is computed by using

the model.

During mining, impact on noise due to project can sometimes be significant for the

workers working in certain process zones if exposed for larger duration and

therefore, mitigation measures suggested for the workers protection should be

adopted. During operation phase, the major noise generating sources from the

mining activity are drill machine, dumper & Excavator cum loader.

The noise levels from IBH-10 is about 85.1 dB(A) without any enclosures at the

distance 10 m away from the source. To assess the worst case impact, a maximum

noise level of 88.5 dB(A) has been considered for noise modeling.

Basic phenomena of the model are the geometric attenuation of sound. Noise at a

point generates spherical waves, which is propagated outward from the source

through the air speed of 1,100 ft/sec, with the first wave making ever-increasing

sphere with time. As the wave spreads the intensity of noise diminishes as the fixed

amount of energy is spread over an increasing surface area of the sphere.

The assumption of the model is based on point source relationship i.e. for every

doubling of the distance the noise levels are decreased by 6 dB (A). Point source

propagation is defined by the following equation:

LP2 = LP1 – 20 log r2/r1.

When LP1 and LP2 are sound pressure levels at points located at distances r1 and

r2, respectively, from the source.

The following table gives the distribution of cumulative noise levels due to the

proposed noise generating sources.

Predicted noise levels (without attenuation)

Distance from the source (m) Noise Levels (dB (A)) 10 88.5 20 82.5 30 79.0






40 76.5 50 74.5

100 68.5 150 65.0 200 62.5 250 60.5 300 59.0 350 57.6 400 56.5 450 55.4 500 54.5

Noise level at the mining lease area calculated from the above equation without

considering any attenuation factors. The projects likely to contribute to the existing

noise levels, however, the proposed green belt shall help attenuating the noise.

Thus it can be concluded that the noise environment of the area does not reached to

an objectionable level and adverse effect of mining activity over noise environment

of the area is low.

Mitigation Measures

i. Acoustic treatment for rotating equipments

ii. Compulsory use of personnel protective equipment (PPE) such as ear plugs

for the workers

iii. Installation of noise generating machinery, strictly in compliance with the

recommendations of the manufacturers. This would ensure an installation

free from vibration and exhaust leaks which are also major contributors to

increased noise levels

iv. Provision of insulating caps and aids at the exit of noise source on the

machinery.

v. Use of damping materials such as thin rubber sheet for wrapping the worn

places of compressors, generators etc.

vi. Shock absorbing techniques to reduce impact

vii. Use of physical barriers and green belt development around the mine to

restrict the noise from going outside the proposed mine boundary during

operation






Ground vibration

When an explosive charge is fired in a hole, stress waves propagate radically in all

directions and cause the rock particles to oscillate. This oscillation is felt as ground

vibration. The mining operations using deep hole drilling and blasting using delay

detonators are bound to produce ground vibrations.

Blasting, in addition to easing the hard strata, generates ground vibrations and

instantaneous noise. Ground vibrations from mine blasting may be expressed by

amplitude, frequency and duration of blast. The variables, which influence ground

vibrations, are: controllable and non-controllable. The non-controllable variables

include: general surface terrain, type and depth of overburden and wind. Similarly,

the controllable variables include: type of explosives, charge per delay, delay interval,

direction of blast progression, burden, spacing and specific charge and coupling ratio.

LAND ENVIRONMENT

The original topography of the part area will be affected mainly due to the actual

operation. The activity will affect the present landscape. Topographically the

majority of the area has medium relief undulating topography while the southern

part has sharp gradient, the highest elevation is of 485m in the southerly side

hillock direction and the lowest one is 440 in the north east, thus the total elevation

difference is of 45m. The southern part is covered by scattered plantation. The

gradient is toward the northeast direction is steeper in the southwest direction.

This Dolomite & Limestone mining lease area does not possess threat to any forest

growth as existing land use of the site is only a barren land. So that there is no

chance of loss of forest due to mining activity. Thus there is no adverse impact over

land environment due to the mining activity.

Land Reclamation

Reclamation and rehabilitation is proposed during proposed 1st year onward

working entire mine waste will be used for backfilling purposed. Since further

exploration is proposed to completely delineate ore bearing areas within the

leasehold, complete reclamation programme cannot be given at this juncture but

waste will be spread in worked out areas to the maximum extent possible. Presently






5.464hect area has been excavated. During the past mining about 1970m3 OB of

mine waste has been generated. Out of 5.464hect excavated area, 0.1140hect area

fully mined out. No soil generated so far from the mine. During the lease period re-

handled the old dump. No dumping has been proposed. During the lease

period/mine life about 17.67hect area will be excavated and about 0.1140hect area

will be backfilled using OB/mine waste. Rest of excavated area converted as a water

reservoir which is 14.913 ha. Details of proposed reclamation are given as follows

during lease period which will be used for backfilling purpose.

Solid Waste Management

Mining shall be carried out by open cast other than fully mechanised method using

explosive in the mining lease area. During entire mining operation no soil, quartz

and weathered granite will be generated.

The proposed site is in mineralized zone and there is no soil. The soil present earlier

in pockets here and there has mostly been scrapped off. During the last mine plan

period waste has been generated and same has been stack as dump. About 0.2780ha

area has been covered under old dumps. This will be loose form in the shape of

chips and lumps. During the proposed two years mining, no OB/mine waste will be

generated. The existing OB/waste generated will be use for backfilled in excavated

area during lease period. No dumping has been proposed.

ECOLOGY (FLORA, FAUNA)

The major area of the core zone is waste land, hence, no major adverse impact is

anticipated. The core zone covered by sparse vegetation of grass only; hence, no loss

of flora is expected. No special fauna is present in the ML area; therefore, no adverse

impact on fauna is anticipated.

There is forest land located in nearby area of the mines. Moreover, there are no

known rare, endangered species in this region. Hence, there will be no considerable

impact on the biological environment. The proposed extensive green belt will

enhance the vegetation quality as well as aesthetic quality of the area. Thus there is

no adverse impact is envisaged over biological environment due to proposed mining

activity.






SOCIO-ECONOMIC CONDITIONS

No house holds will be displaced or required to be rehabilitated. The socio-economy

of the study area has tremendously improved and the process is continuing for

future as well.

Some of these impacts would be beneficial.

i) The project will have a strong positive employment and income effect, both

direct as well as indirect.

ii) The project shall speed up the growing view on importance of education among

people in study area.

iii) The project is going to bring about changes in the pattern of demand from food

to non-food items if sufficient income is generated.

iv) The project is not going to influence the existing traditional agricultural situation

significantly. It may help to improve agricultural production by way of providing

additional income to the farms from supplementary sources.

People perceive that the project will bring handful gains by way of creating

significant job opportunities along with development of social infrastructure.

Impact on Socio - Economic Aspects

It is obvious to assume that the activities of the mining operations will improve the

socio-economic levels in the study area. The anticipated impact of this project on

various aspects is described in the following sections:

Impact on Human Settlement

There is no human settlement in the ML area. No rehabilitation and resettlement is

necessary for the mining operations. The mining operations will thus not

disturb/relocate any village or settlement. No adverse impact is anticipated on any

settlement.

Impact on Population Growth

All of the mine operating personnel will be accommodated in the nearby villages.

Hence, there will not be any impact of the population growth on near by

surroundings.






Impact on Literacy and Educational Facilities

The literacy rate of the study area is poor. This is not likely to change, as the mining

activity does not envisage any inflow of educated manpower to the mine site.

However, the socio economic benefits arise from the mining activities may increase

the literacy and educational facilities in the buffer zone.

Impact on Civic Amenities

The civic amenities have already been developed due to mining operations in the

area. However, there will not be a significant shift in terms of civic amenities due to

the mining operations at mines.

Impact on Health Care Facilities

Mining activities involve accidents during operation phase. Thus, it is imperative to have

proper health care facilities near the mining area.

Impact on Economic Aspects

The proposed mining activities in the area will provide employment to persons of different

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

The employment potential will ameliorate economic conditions of these families directly

and provide 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.

Impact on Sensitive Locations

There are no buildings of public interest and monuments notified by archaeological

department in and around the mine lease area. Thus, there will not be any adverse impact

on the tourist/religious or historical important places due to mining project.

GREEN BELT DEVELOPMENT

The massive afforestation planned for the project shall generate a forest having

greater tree density. The proposed extensive will enhance the vegetation quality as

well as aesthetic quality of the area. Thus there is no adverse impact is envisaged

over biological environment due to ongoing mining activity. The afforestation is

carried out in a systematic and scientific manner by digging pits of

45cm*45cm*45cm manually at the interval 2m*2m*2m. The afforestation is carried






out in a systematic and scientific manner. The details of year wise area and nos. of

sapling planted area as under:

Afforestation plan

S. No. Year area in Hect Plantation in No. 1 Existing 0.2 200 2 1st 0.5 750 3 2nd 0.5 750 4 2013 to 2021 3.6 5400 Total 4.8 7100

An average of 1500trees/ha will be planted as against barren land which is existed

prior to mining operation with in mining leasehold area.

Post plantation cares that will be followed are:

• Fencing of plantation areas

• Using of Cow dung manure and fertilizer like urea and NPK for batter growth

of the sapling

• Regular watering of the plants

• Local species are chosen which can grow easily on the available soil

• Regular watch and ward

8. IMPACT EVALUATION

An attempt has been made to evaluate the impact of project in terms of both quality and

quantity by using modified matrix method for crucial environmental parameters. The

environmental impact evaluation of possible effects as a result of proposed mining area

is primarily based on study of objectives, process, surrounding environment etc. The

aspects such as water, air, land and related issues have been assessed on the basis of

mining operations for similar activity. The environmental impacts identify the possible

relationship of proposed mining operations with respect to environmental parameters.

Their relationship can be beneficial or adverse and can be further classified as short

term, long term, reversible, irreversible, local or regional.

9. ENVIRONMENT MANAGEMENT PLAN

9.1 Reclamation of Land

Reclamation and rehabilitation is proposed during proposed 1st year onward

working entire mine waste will be used for backfilling purposed. Since further






exploration is proposed to completely delineate ore bearing areas within the

leasehold, complete reclamation programme cannot be given at this juncture but

waste will be spread in worked out areas to the maximum extent possible.

Presently 5.464hect area has been excavated. During the past mining about

1970m3 OB of mine waste has been generated. Out of 5.464hect excavated area,

0.1140hect area fully mined out. No soil generated so far from the mine. During the

lease period re-handled the old dump. No dumping has been proposed. During the

lease period/mine life about 17.67hect area will be excavated and about

0.1140hect area will be backfilled using OB/mine waste. Rest of excavated area

converted as a water reservoir which is 14.913 ha. Details of proposed reclamation

are given as follows during lease period which will be used for backfilling purpose.

9.2 Green Belt Development

Plantation will be done within the northeastern 7.5 m barrier zone of the lease area.

Site for proposed plantation is chosen, so as to facilitate proper monitoring and after

care of plants on regular basis. Programme of afforestation is decided keeping in view to

improve environment. Plantation is proposed by considering that each plant will cover

about 3x3 m area and survival rate is considered about 80%. Plants like Neem, Mango,

Karanj, Subabool and other varieties will be put in consultation with local forest

department. Sapling will be planted in 30-cm. deep hole covered with soil and manure.

A Mali will take care of plants for their better survival conditions.

Afforestation plan

In initial stage the green belt will be developed in following manner.

S. No. Year area in Hect Plantation in No. 1 Existing 0.2 200 2 1st 0.5 750 3 2nd 0.5 750 4 2013 to 2021 3.6 5400 Total 4.8 7100

Post plantation cares that will be followed are:

• Fencing of plantation areas

• Using of Cow dung manure and fertilizer like urea and NPK for batter growth of

the sapling






• Pesticides are regularly sprayed to protect the plants form different insects.

• Regular watering of the plants

• Local species are chosen which can grow easily on the available soil

• Regular watch and ward

9.3 Measures to Improve Socio-Economic Conditions

The impacts of the project would be felt in an integrated manner on the socio-

economic environment in the study area. There is no village in core zone and

further no displacement is required for the proposed project and therefore impact

will be positive side rather negative. The impacts on the different components viz

employment, housing, educational, and medical and transport facilities, fuel

availability, economics, status, health agriculture is not significant because size of

project is very small. However, it would definitely increase the employment

opportunity (primary as well as secondary) in the project area. Some of these

impacts would be beneficial.

• The project will have a strong positive employment and income effect, both

direct as well as indirect.

• Migrant-Non migrant ratio shall shift towards migrant side. This will happen

because of (i) better employment opportunities due to this project and (ii)

relatively low agricultural yield through traditional agricultural practice

with monocrops.

• The project shall speed up the growing view on importance of education

among people in study area.

• The project is going to bring about changes in the pattern of demand from

food to non-food items if sufficient income is generated.

• The project is not going to influence the existing traditional agricultural

situation significantly. It may help to improve agricultural production by

way of providing additional income to the farms from supplementary

sources.






• People perceive that the project will bring handful gains by way of creating

significant job opportunities along with development of social

infrastructure.

9.4 Air Pollution Control Measures

Following measures shall be taken to mitigate the effect of mining operation over

ambient air environment:

2. Regular spraying of water by water sprinkling system over haulage roads.

3. To reduce dust generation during loading operation water shall be sprayed

over the muck pile to the loaded;

4. To reduce dust generation during plying of dumpers on the haul road. Water

sprinkling is done at frequent intervals. Water sprinklers shall be installed

at the mine haulage road;

5. To reduce spread of dust, plantation along the mining lease boundary and

plantation shall be also done along haul roads.

6. Periodic maintenance of haulage roads.

7. All over burden dumps shall be stabilized with legumes and grass to prevent

the erosion of soil and arrest the dust emission during windy days.

In addition to the above following additional mitigation measures has been

adopted and it is expected to continue in future also:

1. Dust mask has been provided to all workers working in dusty atmosphere.

2. Tree Saplings has been planted at the periphery of mining lease

3. Regular maintenance of vehicles and machinery’s has been carried out in order

to control emissions;

4. A good house keeping and proper maintenance has been practiced which will

help in controlling pollution.






9.5 Noise Pollution Control Measures

The main sources of noise in mining activity are drilling, blasting, loading

equipment, etc. Following mitigation measures should be taken to control noise

pollution:

1. All moving parts of machine shall be properly lubricated;

2. Non-moving parts of machine shall be properly fastened;

3. A barrier of overburden at mine boundaries shall be made and three rows of

trees are proposed to be planted to reduce propagation of noise;

4. Noise barriers, silencers and enclosures shall be incorporated for equipments,

which emit high noise levels.

5. All the basic equipments and various machineries shall be kept well maintained.

6. Thick green belt around the mining pit and along the haulage roads.

7. As far as possible heavy and noisy workers shall be avoided during nighttime.

8. Acoustic treatment for rotating equipments

9. Compulsory use of personnel protective equipment (PPE) such as ear plugs for

the workers

10. Installation of noise generating machinery, strictly in compliance with the

recommendations of the manufacturers. This would ensure an installation free

from vibration and exhaust leaks which are also major contributors to increased

noise levels

11. Provision of insulating caps and aids at the exit of noise source on the machinery.

12. Use of damping materials such as thin rubber sheet for wrapping the worn places

of compressors, generators etc.

13. Use of physical barriers and green belt development around the mine to restrict

the noise from going outside the proposed mine boundary during operation

9.6 Water Pollution Control measures

Following measures have been taken to avoid accumulation of water:

1. Pump having required capacity shall be installed to lift accumulated rain water.

2. There shall not be no over flow on wash off from dumps nor is there any

beneficiation plant. Only rainwater is pumped out of the mine;






3. A silt-settling tank shall be constructed in barrier zone area to settle heavy particle,

and this tank shall be filled up by seepage water. The water shall be given to the

villagers for the agricultural purposes.

4. Quality of water accumulated in the working pit may be checked during monsoon.

5. It shall be ensured that silt content in the mines discharged is minimum.

6. It shall be ensured that quality of drinking water for the worker is hygienic and

good sanitation system is available.

On the other hand the accumulated water in the pit will ultimately recharge the

local ground water and provide a source of irrigation to the local population at

abandoned stage.

9.7 HEALTH AND SAFETY

The main factors of occupational health in Manganese mine are fugitive dust and

noise. Safety of employee during blasting operation and maintenance of mining

equipment and handling of explosive materials are taken care of as per mine

regulations 1961. To avoid any adverse affects on the health of workers due to dust,

noise and vibration sufficient measures have been provided in the mining project.

During operation of the mines, care should be taken to ensure healthy and safe

working conditions for all workers. Periodical medical check up is necessary.

Provisions of pure and clean drinking water, safety provisions, training of all

personnel to deal with accidents are required for an effective environmental

management.

The Mining Lease Owner is conscious of its moral and legal obligation to prevent

hazards and to provide healthy working environments. In addition, following

activities shall be carried out in order to healthy and safe working condition:

• Provision of wet drilling and drilling with build dust catcher;

• Provision of rest shelters for mine workers with amenities like drinking water,

fans, toilets etc.

• Provision of personal protection devices to the workers;






• Dust suppression of haul road; and

• First-aid facilities in the mining area.

• Making of annual budget for the safety and health of their employees and provide

sufficient facilities in order to effectively implement the health and safety

measures.

• The management shall carry out periodical audit of safety and health with view to

ascertaining the effective implementation of policy.

• Regular medical examination shall be conducted for the employees. The Medical

Officers renders timely advice to the Management on preventive measures and safe

guards.
