SOCIO-ECONOMIC CONDITION OF THE AREA

Based on the sample survey of the study area comprising of 10 km radius, the

general socio-economic conditions of the local people can be summarized as

below.

There are 35 villages within the study area comprising of 6935 house hold.

Majority of the population are industrial workers dependant on the local

mines.

S.T. population of 64.83 %, which dominates the local population.

Level of literacy is very low, which corresponds to their level of poverty.

Employment in agricultural sector is seasonal and people look forward for

miscellaneous jobs for their survival in the lean months.

Mining could provide an important employment opportunity to the workers.

Majority of the workers is addicted to country liquor that degenerate their

working abilities.

All the villages have dug wells and Hand pumps for drinking water.

All most all villages are provided with electricity, 9 villages have bus stand

which are 5 to 10 km away from rest of the villages. All of the villages are

connected with kuchha and pucca roads.

ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES

The dust generated from mining activities is the primary source of air pollution.

The emission sources include excavation and mining of ore bodies, drilling,

blasting, screening/sizing and transportation within the project area. During air

quality monitoring it is observed that dust generation is of short term and settle

quickly within close ranges. There is very less scope of spreading of dust

particles to the nearby residential areas as these operations are carried out at far

off distances from the habitation areas. The impact of mining on the study area is

assessed using ISCST –Area & Line Source modeling and the resultant

concentrations so derived are as below.

Mining activities and related operations can cause several beneficial and adverse

imp0acts on the environment. The adverse impacts are proposed to mitigate.

Using „matrix method‟ the impact on the environment has assessed.

The expected beneficial impacts on the society are Health, Population/Migration,

Employment, Literacy, Services and Aesthetic sense, The mining operation will

generate direct employment for 349 no. of people.

Communication, education, medical, power and employment facilities will be

improved.

Various mining operations will generate dust and gaseous pollutants. In a view to

the scale of mining and existing environmental back ground condition it is

anticipated that increment impact due to the mining operation will be within the

prescribed limit. Further mitigation measures like water sprinkling and plantation

will reduce the pollution level in the area.

Contamination/siltation of surface water might occur due to mixing of runoff

during rainy season with high-suspended particles, likely to be caused due to

wash out of overburden. As it is proposed to construct settling tank and garland

drain around the mining area the level of concentration of suspended particles in

the surface water shall be well within the prescribed limit.

The contamination of surface water may cause diseases in the area. Treatment of

water will be done. Medical treatment will be provided as per the requirement.

The impact on ground water will be marginal since proposed mining activities

will be much above the ground water table.

Due to the opencast mining project, the noise level of the area due to drilling,

blasting transportation and running of heavy machineries will increase.

Controlled blasting, proper maintenance of machineries and soundproof cabins,

noise level can be minimized.

The loss of vegetation due to mining activity and degradation of forest land will

be compensated by the Compensatory Afforestation to be implemented as per the

Forest Act. Further, due stabilization of dumps with rehabilitation will increase

the area of plantation in order to bring an ecological balance.

There will be less chance of improvement in agriculture in the degraded land.

However, there will be generation of employment and revenue for the local

people from various ancillary mining activities including direct employment.

ENVIRONMENT MONITORING PROGRAMME

An environmental monitoring cell will be formed for regular environmental

assessment on air, water, noise and soil qualities at nearby habitational area. Four

permanent Air quality stations will be fixed as per the SPCB guidance to monitor

the AAQ in quarterly basis. Quarterly water samples of ground water and surface

water shall be collected and analysed. Noise level monitoring at Noise generating

points and AAQ locations shall be done in quarterly basis.

ADDITIONAL STUDIES

Additional studies like soil erosion and nutrient quality at river bed soil will be

taken up.

PUBLIC HEARING

As per the statutory provisions, the Public Hearing Meeting was held successfully

on 10.4.2012 at 11:00 AM at Dadwan village of Keonjhar District, Odisha in

respect of Environmental Assessment of Inganijharan Iron & Mn Mines of Sri.

PROJECT BENEFITS

All the industries using iron and manganese as raw material will be benefited and

add to the earning of revenue. The iron and manganese will be utilized in sponge

iron, steel, smelter depending on their grade. Derived from the existing

calculation, the net benefit at the end of the project at the present rate is Rs

328874.00 lakh. The ratio of Cost to benefit comes to be 1:1.33 or 1:1.3.

Therefore the project is very much feasible.


The mining activities will have certain adverse effects on the existing

environment like air, water land and noise. The following protection measures

will be adopted to minimize pollution.

Provision of planting emission, noise absorbing species (with dense/thick

type canopy), soil erosion control and nutrient enhancing species

To suppress fugitive dust, provision of water sprinkler, dust extractor etc at

the dust generation source

Adoption of control blasting techniques (suing advance non-electric

detonator)

Construction of garland drains around the quarry area and dumps with proper

gradients

The settling tank will have adequate dimension

Drain and channel on Overburden dump in to sedimentation pond before

discharging into natural drainage

Proper maintenance of plant and machinery

Providing sound proof cabins with proper ventilation

Provision of personal protective equipments according to the pollution

Dump yard stabilization through grading, compacting and suitable plantation

Stone pitched walls in garland drains will be prepared to arrest flow of loose

sediments

Provision of speed breaker (stone pitching) at regular intervals in garland

drains

Silvipastoral plantation will be made to control erosion on dump slopes

Phase wise reclamation through backfill shall be followed as per the Mine

Plan

No displacement is required for the proposed project. Hence R&R action plan is

not applicable for the project.

PLANTATION PROGRAM

Plantation over an area of 4.3hactareas have already been done with 8600 no of

saplings @ 2000 saplings per hectare. More plantations will be done gradually

over the mined out area after backfilling. At the end of the mine life 79.314ha of

area will be coved under plantation which is about 70% of the total area. Beside

reclamation, plantation in the safety zone area shall be carried out under the

plantation program as per the guidance and supervision of the State Forest

Department.

CHAPTER 1

INTRODUCTION

1.0 PRELUDE TO THE PROJECT

Mining is one of the core sector industries, which plays a significant role in the

process of country‟s economic development with some unavoidable

environmental impacts. While sustainable development is the key issue, the

mining operation has to achieve more positive results with minimum degradation

of the environment.

Mining operational plan including details of method of mining, environmental

report and reclamation plan etc which are few requisites from investor for

efficient & sustainable mining operation. It is necessary that lessee has to prepare

a formal environmental impact assessment (EIA) and an environmental

management plan (EMP) report for approval before commencement of mining

activities. The reclamation plan for EIA/ EMP provides the basis for Governments

decision to permit environmental acceptability.

In order to make effective sustainable mining programme, it is advisable to

conduct a baseline survey of the existing environmental attributes to evaluate

likely environmental impacts due to proposed activities. This study has been

conducted in order to predict the proposed impacts and to prepare a scientific

Environment Management Plan. Irrespective of magnitude of operation, attempts

have been made to maintain ecological balance of the study area.

As per EIA Notification 2006, published on 14th September 2006, all projects or

activities, including expansion and modernization of existing projects or activities

or change in Product Mix, falling under Category „B‟ in the Schedule shall require

prior Environmental Clearance from State Environment Impact Assessment

Authority(SEAIA), Ministry of Environment & Forests, Govt. of India.

In order to renewal the production of 0.6MTPA of iron and 0.075MTPA of

manganese for INGANI JHARAN MINES (Iron & Manganese Ore), Sri Bikas

Chandra Deb, the Lessee, has to obtain Environmental Clearances as per EIA

Notification 2006.

The scheme of mining of Inganijharan Iron and Manganese Mines of Sri B.C.

Deb was approved Vide Let. No. BBS/KJ/Fe & Mn/MS-168 dt.21.12.2006 by

IBM for a period of 5 years from 2004-05 to 2008-09. Further under Rule 23- B

of MCDR-1988 the revised scheme of mining with progressive mine closure plan

was approved vide letter no. MP/OTFM/18-ORI/BHU/2014-15 dated 06-04-2015

for the period of 20-11-2013-14 to 2017-18.

2.2 PHYSIOGRAPHY AND DRAINAGE

2.2.1 PHYSIOGRAPHY

Inganijharan applied (Renewal) M.L Area (Latitude: 22000‟45‟‟ N and Longitude

85027‟30‟‟E) of Late M.S. Deb is located at a distance of about 5km NE of Joda

township and falls on the survey of India Toposheet No. 73 F/8.

The area is surrounded by Baitarani Reserved Forest in the North, North-West,

South and South-West directions and Baitarani River in the East. The highest

peak of the locality is Baspani pahar (RL 686) situated in the N-W direction. (Ref.

Key Plan- Plate No.1). Other Hill Peak is Churia Pahar ( RL 600).

Banspani Railway siding is located at a distance of about 5 km in the S-W

direction from the area.




Pag

2.2.2 DRAINAGE

River Baitarani flowing close to the eastern side of the applied mining lease area

constitutes the principal drainage system of the locality. One small seasonal nalla

flowing centrally in the area from west to east collects the surface run-off water

and discharges to Baitarani River.

The drainage pattern of the region is diagnosed as a coarse “trell” pattern of

drainage following the local topography as shown in Fig no. 2.2.

2.3 GEOLOGY

2.3.1 REGIONAL GEOLOGY

The iron ore deposit in the area forms a part of the South - Eastern portion of the

Singhbhum - Keojhar - Bonai belt, also known as the Jamda - Koira valley and is

represent by a narrow N- Easterly plunging folded synclinorium of 60 km. long

and 25 km. width. The precambrian horse - shoe shaped belt is well known for its

large reserves of iron and manganese ore. The general strike is north east to North,

dips are moderate to West. The Western limb of the synclinorium is slightly

overturned, at some places.

The belt was first reported by Jones in 1934 and has been studied in detail by

several eminent geo-scientists since then. The major litho types are:

metamorphosed sandstone, lithic wacke to arkose and/or volcanic tuffs and /or

shale. In the lithic wacke, mostly in the east, BIF and iron ore fragments are

common. Shaie, lavas, volcanics, pyroclastic tuffs, Banded Iron Formations

(BIF) including Banded Haematite Jasper(BPJ), Banded Haematite Chert (BHC),

Banded Haematite Quartizite (BHQ) and the group of Rocks are exposed.

The regional stratigraphic succession of the rock types is as given below:

The precambrian rocks of this region comprising of basic lava, tuffs, banded iron

formation (BIF), shales, conglomerates and sandstones etc. were mapped for the

first time by Jones (1934). The stratigraphic succession established by Jones has

largely been modified later by Dunn (1940). Based on detailed mapping in the

northern parts of the belt, Dunn recognised a new group lying unconformably

over the Iron Ore Group which he named as the "Kolhan Group". The rock types of

the area belonging to the Kolhan Group lies to the north of Noamundi in Bihar.

The most acceptable litho - stratigraphic succession for the belt was proposed by

Murthy and Acharya (1975). They identified different depositional facies and

proposed a more detailed stratigraphic succession. They also proposed a new

name the "Koira Group" to the rocks of Bonai - Keonjhar belt. The stratigraphy

suggested by Murthy and Acharya (1975) is as follows.




Pag

2.3.2 LOCAL GEOLOGY

Rocks of the manganiferous mixed facies formation occupy a major part of the

Bonai - Keonjhar Belt. This formation being younger to the Banded Iron Formation

( BIF ) occupies the inner slopes of the residual hill ranges constituted originally of

the resistant jaspillites. The manganese deposits of Inganijliaran Iron &

Managancsc Mines are located on (the outer slopes of the eastern limbs of the

synclinorium. Hills and domes in the locality are composed of Banded Iron

Formation,

Banded Iron Formation (BIF) contains iron ore and the shale horizons contain

manganese. The boundaries of these lithounits are mostly covered with soil

or laterite. The litho contacts are observed to be gradational rather than sharp.

The litho contacts delineated on the Geological Plan [\Plate No. 4) are,

therefore, inferred.

It is observed that the manganese ore deposits occurring as lenses, pockets

and veins are confined to variagated shale horizon. The iron ore deposits are

float iron ore & occupied mainly on the hill slope of Southern and Nothern

part of the lease. '

The manganiferous shale with brecciated and pisolitic lateritcs and cherts

occupy the central part of the area. Manganese occur as small pockets /

patches within the shale zone. Laterite / soil cover "observed normally in the

area varies in thickness from 2 to 3 m above the shale formations of the area.

The mode of manganese mineralisation can be considered to be similar to

those encountered in lateritoid deposits. The irregularity of shapes and sizes

can be attributed to local tectonic activities like secondary folding, faulting

and weathering.

2.4 RESERVES

Ore reserves have been calculated by cross sectional area method for proved,

probable & possible category.

2.4.1 METHOD OF RESERVE ESTIMATION

There are four existing pits of iron ore namely iron pit-1, iron pit-2, iron pit-3 and

iron pit-4 and seven manganese pits namely pit-1 to pit-7 present in the lease

area. These pits have been worked up to different mRLs. Reserve of iron and

manganese within the ML area has been calculated based on available existing

quarry information. An interpreted ore boundary as per UNFC has been plotted

around the existing quarry taking influence of 150 meter for iron ore from the

existing quarries i.e. 50m as proved zone, another 50m as probable zone around

the proved zone and 50m again as possible zone around the probable zone as the




Pag

e20

float iron ore extends laterally. But for manganese, the proved ore boundary has

been marked at a lateral distance of 25 meter from the existing quarries. No

further lateral extension has been assumed due to deceptive behavior of

manganese ore. The reserves within the ore bearing zone have been estimated by

cross sectional area method.

Depth-wise continuity:

As observed in the field, float iron ore is exhausted in the existing iron quarries as

bottom shale is exposed. Therefore no depth-wise extension has been taken in to

consideration for iron ore. The depth of the quarry has been extrapolated laterally

to calculate the reserve of ore.

However, for manganese ore depth-wise 4m has been considered as probable

zone below the proved zone and another 2m below the probable zone has been

considered as possible zone for calculation of reserve.

Categorization of Reserve:

Iron ore:

Proved (G1)- In the ensuing plan period only existing quarry features have been

taken in to consideration as there was no authenticated data of existing boreholes

available with the lessee. Iron pits namely Pit-1 ,2, 3 & 4 have been worked up to

519 mR.L, 480 mRL, 478 mRL and 495 mRL respectively. After plotting the ore

boundaries and altitude of iron ore occurrences on the geological cross sections,

the depth-wise ore limit has been taken till the end of occurrence of ore in the

corresponding existing quarries and 50 meter lateral influence from the pit

boundary. The depth-wise ore limit and 50 meter lateral influence from the pit

boundary has been considered as proved zone.

Probable (G2)-Similarly there is every chance of potential of ore beyond the

proved zone. So, 50 meter around the proved zone has been categorized as

probable zone.

Possible (G3) - Similarly 50 meter beyond the probable zone has been

considered as possible zone.

Manganese ore:

Proved (G1)-No bore hole has been drilled in the manganese zone. The bottom

of the manganese pit has been assumed as the proved ore limit. All the ore up to

the bottom of pit and 25 meter laterally from the pit end has been categorized

under G1.




Pag

e21

Probable (G2)- 4 m below the proved ore zone in the manganese patch has been

assumed as probable ore zone.

Possible (G3)- Similarly possible ore zone in the manganese pit has been

assumed as 2 m below the probable ore zone.

The proved, probable and possible lines have been marked on the geological plan

and geological sections. (Plate: III, III A)

2.4.2 RESERVE CALCULATION

A total of twenty one geological cross-sections have been prepared to depict the

proved, probable and possible thickness of ore zone.

It has been found that the iron and manganese horizons in the area occur

intercalated with shale and the past mining activities and recent analysis suggest

that recovery of iron and manganese with respect to total volume of the ore zone

is around 78% and 30% respectively. Further tonnage conversation factors of 3.5

MT/m3 & 2.8 MT/m

3 have been multiplied to the volume of ore to estimate the

tonnage of geological reserve of iron ore and manganese ore respectively.

The formula adopted to calculate the geological reserves is as follows.

Q=C X L X RF X T

Where Q=Quantity of geological reserve in MT

C= Cross sectional area (sq m)

L= Length of influence (m)

RF= Recovery factor (0.3 for Mn and 0.78 for iron)

T= Tonnage conversation factor (3.5 MT/m3 for iron & 2.8 MT/m

3 for

manganese)

The computed geological reserve in reserve table may be summarized as follows

As already mentioned the iron and manganese within the deposit is found to be

mostly interbanded with shale. Therefore, while estimating the geological

reserves, a factor of 22 % and 70% has been assumed as IB for iron ore and

manganese ore respectively.

Mineable reserve

Mineable reserve has been calculated deducting the reserve that would be

blocked under the pit slope and within the safety zone. The mineable reserve

within the area thus is as follows.

As mentioned above, iron ore has been divided into two categories namely Fe ore

containing +65 % or above which has been calculated to be 60% of the total

quantity of saleable ore and Fe ore containing 58-65% has been calculated as

40% of the total quantity of saleable ore. Similarly In case of manganese




Pag

e25

ore10%,10%,20% and 45% have been considered as grade-wise occurrence of

different grades of Mn ore namely MnO2, HG (>45%), MG (35-45%) and LG

(25-35%) of total quantity of saleable ore.

Sub-Grade: Iron ore containing 45% to 58% Fe has been considered as sub-

grade. No mention has been made in the submitted annual returns as described

above about sub-grade ore. In the absence of this, 10% of the total quantity of ore

has been assumed as sub-grade iron ore based on field observations. However, as

per above calculation, 15% of the total quantity of Mn ore has been assumed as

sub-grade ore having Mn% in between 10 to 25%.

Recovery Factor: As revealed from the analysis results (Annexure XVIII)

recovery of saleable iron ore is 70%, that of sub-grade ore is 8% and rest 22% is

rejects, i.e. 78% constitutes ore and 22% waste. During calculation sub-grade has

been taken as 10% of total ore which is equivalent 8% of excavation.

Similarly, recovery of saleable Mn ore is 25%, that of sub-grade ore is 5% and

rest 70% is rejects, i.e. 30% constitutes ore and 70% waste. During calculation

sub-grade has been taken as 15% of total ore which is equivalent 5% of

excavation.

l) Mineral Reserve/Resources- Mineral resources has been estimated based

on level of exploration with reference to the threshold value of mineral.

2.5 MINING

The Inganijharan iron & manganese mine is an old existing mine. The mining was

initially carried out by opencast manual method and subsequently the plan has

been revised for semi mechanized (Group-A-OTFM) with screening facility to

produce 0.6 MTPA Iron and 0.075 MTPA Manganese during the recent

conceptual period.

The opencast methods are deployed and mining runs in a single shift. Breaking of

hard strata will be done by drilling of 32 mm diameter drill holes and subsequent

blasting. Secondary drilling by using jackhammers along with blasting to handle

big boulders and toes, blasting will be carried out by ANFO.

Excavation and loading will be done by the excavator (S) and transporting will be

done by 10 ton capacity dumpers.

Mining activities has been carried out in the lease area since 1953. Presently the

mine is temporarily discontinued since November 2009 for required statutory

clearances. In course of mining 4 nos. of iron ore pits and 7 nos. of manganese pits

have been developed in the lease area. The iron quarries extend from about 940 S to

1530 S in north-south direction and 1230w to 1600W in east-west direction.

Manganese pits namely Mn pit-4 & Mn pits -5 are presently water logged. Details

of each individual pits have been given below.

There are few mineral stack yards and fines stack yards present over an area of

3.246 ha. near the existing quarries within the lease area. Some of these stacks are

having Fe% from 58 to 62%. During the mine operational period, the cut-off grade

was 62 % for iron ore. These stacks were termed as sub-grade stack. At present as

cut-off grade of iron ore is changed to 58 %, these stacks have been considered as

saleable stack yard. From this point of view, presently there is no sub-grade stack in

the lease area. As these mineral stack yards will be sold out simultaneously with




Pag

e28

mining, no rehandling proposal has been considered in the ensuing plan period.

However some of these mineral stack yards will be rehandled for development of

benches in the concerned year.

2.5.1 DEVELOPMENT FOR IRON AND MANGANESE QUARRY

Development / working will be carried out by extending the existing iron &

manganese quarry both laterally & depth ward to achieve the targeted production.

In view of the year wise excavation and development of the mine for RON of Iron

2.6 CONCEPTUAL MINING PLAN

The mineable reserve of iron ore in the lease area is 10,19,176 MT and the

mineable reserve of manganese ore is 12,40,429 MT. Till the end of first five

years of this plan period 805580 Mt of iron ore will be exhausted leaving only

2,13,596 Mt of iron ore. Hence life of the iron ore will be one year after this plan

period. Keeping in view the maximum production of manganese ore target at

75,000 per annum respectively, the life of the manganese working will be

12,40,429 /75,000=16.5 or say 17 years. Hence the life of the mine will be 17

years.




Pag

e30

However, the life of the mine is relative & will depend on increase & decrease of

production in subsequent years and result of exploration.

Ultimate extent and size of the quarry

In the lease area, both iron and manganese ore will be exploited.

At the northern side of the lease area only manganese ore will be developed at

the conceptual period. At the southern side of the lease area only iron ore will be

exploited. A nala is passing at the central part of the lease area. Ultimately three

mineralized areas will be exploited within the leasehold. The extents of

mineralized zones of northern side will be 10,193 m2 and 80,670 m

2 and the

extent of mineralized zone of southern side will be 2, 26,242 m2. Hence the total

ultimate pit limit will be 3, 17,105 m2

or 31.71 hectare. The ultimate size of

ultimate pits of northern side will be 175mx58mx34m & 384 m x210m x 40m

and southern side will be 942 mx240mx45 m respectively. The iron quarry will

reach up to 473 mRL and manganese quarry will reach up to 454 mRL.

Ultimate slope angle

During proposed plan period, the individual benches will kept nearly vertical

with 70º – 80º slope angle. Keeping the height and minimum width of the

benches at 6m and 6m respectively, the ultimate pit slope will be kept at around

45º at the close of the mine.

Ultimate pit limit boundaries

The ultimate pit limit boundaries have been earmarked in conceptual plan

Ultimate capacity of dump

Conceptually swell waste to be generated from the iron quarry will be 4, 64,596

m3

and from the re-handling of the existing iron dump-4 a volume of 22,590 m3

waste will be generated. So a total vol. of 4, 87,186 m3 waste is to be

accommodated over the conceptual dump. But before that a vol. of 2106 m3

waste will be utilized for backfilling of the broken up safety zone near the iron pit

in the western side. It has been proposed to dump the waste generated during the

plan period over existing dump-5. Ultimately this dump will be extended over an

area of 48,274 m2 or 4.83 hectares. The ultimate capacity of the iron dump is 4,

85,080 m3. At the conceptual period the top RL of the dump will be 493 meter

with 3 nos. of terraces.

Similarly, swell waste to be generated from the manganese quarry will be 14,

18,172 m3 and from the re-handle of the existing manganese dump-5 the waste to

be generated is 9261 m3.

From the total waste of 14,27,433 m3, a vol. of 13,786

m3 waste will be utilized for backfilling of the safety zone in between pillar no. 8




Pag

e31

& 9 near manganese quarry. Remaining waste 14, 13,647 m3

will be dumped over

the conceptual dump. During the ensuing plan period the waste to be generated

from the quarry has been proposed to be dumped at the north eastern side of the

lease area. Ultimately this dump will be extended over an area 72707 m2 or 7.27

hectare. Conceptually the top RL of the dump will be 531 mRL. with 6 nos. of

terraces. The ultimate capacity of the dump will be 14, 13,647 m3.

At the end of the conceptual period a quantity of 1, 01,918 MT sub-grade iron ore

will be generated from the quarry. Similarly 1, 86,064 MT sub-grade manganese

ore will be generated from the quarry. These sub-grade ores will be stacked over

the earmarked sites of stacking proposed in the plan period. These sub-grades

will be blended with high grade ores to make them marketable. Therefore, these

sub-grades will be sold out simultaneously with mining and at the conceptual

period there will be no sub-grade ore.

Land degradation and/reclamation/afforestation

At the end of the first five years of the renewal plan period a total area of 25.834

hectare is to be degraded under mining. During conceptual period an area of

33.42 hectare will be mined out. As the total area is yet to be explored and the

existing dumps contain variable proportion of saleable ore and these dumps are

yet to be systematically analysed, no backfilling proposal has been proposed in

this document.

However, based on outcome of the proposed exploration, suitable planning would

be made for reclamation of the quarries. Conceptually, the exhausted quarries

will be backfilled using the wastes of the dumps and the backfilled areas will be

rehabilitated through plantation. The detailed planning can be made in the first

scheme period.

2.6.2 CAPACITY OF WASTE DUMP

Nature and quantity of top soil, overburden/ waste and mineral rejects

The wastes removed from the quarries are mainly composed of laterite, morum,

shale, quartzite etc. The lessee has been dumping the waste material generated

during previous mining operations near the quarry for which it has been proposed

for part re-handling of Dump-4 of iron ore and Dump-5 of Mn to enable

operation of proposed quarries. The total quantity of waste of the existing dumps

is calculated to be about 4, 09,201m3 as indicated below. The details of the

existing dumps are as follows.

In all, eleven nos. of waste dumps exist in the lease area. In course of mining these

dumps have been formed during the previous working years. Some of these dumps

are present within the ultimate pit limit. Retaining wall has been constructed around

the iron dump-1 and 2. As the iron dump- 1 and dump-2 is situated side by side a

common retaining wall of 220 meter has been constructed at the eastern side which

is natural slope to the Baitarani river to arrest the wash-off during rainy season.

In case of existing manganese dumps only D-5 will be re-handled. Plantation has

been done over the dump slopes of remaining existing manganese dumps.

2.6.4 DRAIN DESIGN

The trend of natural drainage pattern in the area is towards east. The surface run-

off water will find clear access into the existing seasonal nala during rains. Part of

the surface run-off water will enter in to the mine workings and may cause

inundation of the same. Since mining is carried out in hilly area, water table is not

intersected as the general ground water table observed in the dug-wells of the

locality is 10 to 15m below the general surface level. In order to make the

working faces dry, pumping of water out of the pits will be necessary during

rainy season. Diesel operated pumps (at least 10 HP) will be deployed to pump

out accumulated water of the mine.

Peripheral garland drains with settling tanks will be provided around the waste

dumps. Width and depth of the drain will be 2m-1m respectively. Slope will be

within 1:30 to 1:50

2.7 MINERAL BENEFECATION

The local sponge iron units and other users require sized ore for their use. Hence

to meet the market needs, a mobile crusher-cum- screening unit of 150 tonnes

will be installed in the central eastern part of the mine which will be shifted

afterwards north eastern side of the property ( non- mineralized zone) after DRP

clearance.

A part of the rated production of the mine i.e. about 4000 tonnes per day will be

crushed and the crusher will operate for 16 to 17 hours per day, i.e. two shifts

per day and the other shifts will be for maintenance . The maximum feed size of

the ore will be 400 mm and depending upon the market requirement the ore will

be calibrated accordingly

2.8 Extent of Mechanization

The proposed quarry will be operated by semi mechanized mining method.

Excavation of hard strata will be effected through drilling and blasting.

Excavation and loading wiil be done by using hydraulic shovels.

CHAPTER 3

DESCRIPTION OF ENVIRONEMNT

3.0 INTRODUCTION

Today the globe is engaged in seemingly endless discussions about the

sustainable development while the mining industry stands on the cross roads

involved in the problems of growth, sustainability and imperative need of an

environmental agenda. Modern technology has enormously magnified out the

ability to extract the minerals. Mining activities represent one of the important

and vital indexes of economic and industrial development of any country. The

occurrence of mineral deposits, being site specific their exploitation cases do not

allow for any choice except adoption of an eco-friendly operation. However, the

methods are required to maintain environmental equilibrium ensuring sustainable

development. Mining processes normally affect the existing environmental

domains of the site. It has both adverse and beneficial effects. In a view to

maintain the environmental commensuration with the mining operations, it is

necessary to undertake studies on existing environmental scenario and impacts of

mining activities on different environmental domains. This would help in

formulating suitable management plans to effect sustainable development plan to

effect sustainable development of the resources.

The entire mining lease area is considerable as core zone. The surrounding area

covering 10 Kms radius from the central part of the core zone is considered as

buffer zone.

An attempt has been made to assess the existing environmental scenario through

generation of different data in the core zone and the buffer zone. Different

environmental parameters required to evaluate the prevailing scenario in the core

as well as buffer zone has been generated/collected and compiled for the period

from March 2010 to May 2010. The details of the sampling locations are

represented in Figure 3.1.

The basic environmental attributes generated and compiled in core and buffer

zone are as follows.

Meteorological Condition

Ambient Air Quality

Water Resource and Quality

The methodologies adopted for the study of different parameters are as follows.

3.1 METHODOLOGY

To complete the assignment as per the scope of works the following methods

have been adopted.

3.1.1 GENERATION OF BASELINE DATA

i) Air quality, noise characteristic and meteorological parameters

To evaluate the air quality, noise characteristics and meteorological parameters

two permanent stations are fixed in the core zone and seven permanent stations

are fixed in the buffer zone by taking into account the prevailing wind conditions

in the study season of Summer monsoon. The sampling locations are selected in

all the direction of the lease area.

The air monitoring station at the mining site in the core zone is fixed with

conventional anemometer to measure the wind speed, wind vane to note wind

directions, thermometer for temperature readings, and hygrometer for relative

humidity data on hourly basis during monitoring periods.

Nine locations are selected for studying the noise characteristics during the study

periods of post monsoon within 10 Kms radius of the central part of the lease

area.

ii) Ecological Studies

This is based on the distribution pattern of the various species of plants and

density of vegetation within the core and buffer zone. Detailed species-wise floral

surveys have been conducted. Random surveys inside core and buffer zone have

been made for determining the faunal characteristics.

iii) Socio-economic and Demographic profile

Main villages within the core and buffer zones have been selected for sample

survey on various aspects to decipher socio-economic and demographic profile.

Data collected during survey have been compared with the data collected from

the Census Survey of 2001.The details of Socio-economic and demographic

profile is appended to this report as Annexure- I.

3.1.2 ANALYSIS OF SAMPLES GENERATED

i) Ambient air samples

High volume samplers/ Respirable dust samplers are used to collect 24 hourly

samples for two consecutive days in a week in each permanent station collecting




Pag

two samples per week, per station. This process continued for the study period

and samples are collected from five permanent stations. The samples, thus

collected are analysed to know the concentration of PM2.5, PM10, SO2, NOx and

CO as per the procedures laid down by the Indian Standards, IS Code No. 5182

(Part IV, II, VI, X, XII respectively).

ii) Meteorological parameters

Meteorological data like wind speed, wind direction, temperature, relative

humidity and rainfall are collected from fixed stations on continuous basis for

three months period. Data for previous years were collected mainly from the

nearby meteorological station for comparison.

iii) Noise characteristics

Noise levels at nine different stations within 10 Kms radius of the central part of

the lease area are monitored. The measurement are made using a sound level

meter on hourly basis for continuous period of one day (simultaneously during

AAQ monitoring) during the study period and are compared with the prescribed

Indian Standards.

iv) Dust fall measurement

Dust fall kits are placed at nine different fixed stations in the core zone and the

buffer zone to note the concentration of dust collected during the period of one

month in the study season. This has been collected as per IS Code No. 5182 part-

I.

v) Water quality

Samples collected from the representative sites have been analysed using IS Code

3025 methodology to note different parameters as per IS Code No. 10500, 2296

and other relevant codes and notification.

vi) Soil quality

Representative samples drawn from five different soil profiles are analysed to

note its physico-chemical conditions using Indian Standard methods (IS Code

2720).

vii) Land use and land cover pattern

Land use and land cover pattern maps are prepared for both core and buffer zone

based on the satellite imageries maps. This is substantiated by actual field studies.

viii) Preparation of report

Based on the data generated/complied, studies on Environmental Impact

Assessment for the area is made which has helped to formulate a suitable

Environmental Management Plan (Chapter 10).

3.2 METEOROLOGY

The mining lease area experiences dry to moist subtropical climate. In a view to

assess the meteorological parameters of the project area and its surroundings,

studies have been made to generate/compile data on rainfall, wind speed, wind

direction, temperature and relative humidity.

3.2.1 RAINFALL DATA

The annual normal rainfall as per the Directorate of Economics and Statistics is

1288.3 mm. nearly 70% of the rain fall was received by the South-West monsoon

during June to September, July being the rainiest month. The data generated in

the project area have also been compared with the data compiled for preceding 10

years from the nearest observatory of the district. Average annual rainfall from

the year 1999 to 2009 of Keonjhar, the district head quarter is shown in Table No.

3.4 DUST FALL

Dust fall kits were placed at each permanent station of core and buffer zone for a

continuous period of one month during study period (March 2010-May 2010) to

know the concentration of dust. Dust fall data are presented in the Table 3.5.

As there is no prescribed limit of Indian Standard for dust fall, the data obtained

have been compared with German norms. The norms as published in Ta LUFT,

1986 are as follows.

Maximum Concentrations:

Annual arithmetic mean -0.35g/sq.m/day or 10.5 tonne/sq.km./month

Parameters Measured During Monitoring

For noise levels measured over a given period of time interval, it is possible

describe important features of noise using statistical quantities. This is calculated

using the percent of the time certain noise levels are exceeded during the time

interval. The notation of the statistical quantities of the noise levels is described

below.

L10 is noise level exceeded 10% of the time

L50 is noise level exceeded 50% of the time and

L90 is noise level exceeded 90% of the time

Equivalent Sound Pressure Level (Leq.)

The Leq is the equivalent continuous sound level that is equivalent to the same

sound energy as the actual fluctuating sound measured in the same period. This is

necessary because sound from noise source often fluctuates widely during a given

period of time.

This is calculated from the following equation:

Leq (hrly) = [L50+ (L10 – L90)2] / 60

Lday: Defined as the equivalent noise level measured over a period of time

during day (06 A.M - 09 P.M).

Lnight: Defined as the equivalent noise level measured over period of time during

night (09P.M - 06A.M).

3.6 WATER REGIME

3.6.1 EXISTING SURFACE WATER BODY

There is one nalla flowing West to East cuts across the area almost along the

central part. This nalla is seasonal in nature, remaining dry during summer

months and it forms a tributary to River Baitarani. It can be seen from plate No.

2, Baitarani River, which is the most prominent river in the region, flows very

close to the eastern boundary of the area and it carries water throughout the year.

3.6.2 WATER LEVEL CONDITIONS

Ground water in the area occurs under pheratic and semi confined conditions in

weathered and fractured stone. Water being a dynamic resource changes its level

continuously depending on its extraction and recharge. The depth of water level

below ground level also varies depending on the local topography, geology and

hydro geological conditions etc.

The depth to water level in post monsoon ranges from 40-80 m in the study area.

3.6.3 GROUND WATER RECHARGE FOR MINE LEASE AREA

The rainfall infiltration method is one of the best methods suggested in ground

water assessment methodology of CGWB 1999 for first approximation of ground

water resources of an area that receives good amount of rainfall. The study area

consisting of 114.930 Ha receives about 1288.3 mm rainfalls annually.

Since the area is occupied by the hard, massive rock, rainfall infiltration is slow,

the standard infiltration factor 10% of the total annual rainfall as mentioned in

CGWB 1997 report is assumed.

Annual Ground Water recharge= Area x Average annual rainfall x infiltration

factor = 114.930 ha x 1.2883m x 0.1 = 14.806 Ham.

3.6.4 WATER QUALITY

14 nos. of water samples (7 grounds and 7 surface water, Fig. 3.1) were collected

from different locations both from core and buffer zone during the study period.

The ground water samples were analyzed and compared with IS 10500 (Table

3.9). All the surface water samples collected are analyzed as per IS 2296 (Table

3.10). It is observed that all the parameters were within the prescribed limit.

3.8 LEACHABILITY STUDY OF OB & ORE

The leachability study is conducted for both iron and manganese ore and over

burden. A five stage sequential leaching procedure viz. exchangeable(F1),

carbonate(F2), reducible(F3), organic(F4) & residual(F5), was used to fractionate

heavy metals (Fe, Mn. & Cr.) for ore and overburden materials in different pH

and temperatures following a standard procedure of Tessier et at, 1979. Out of

these stages, exchangeable (i.e. with 1M MgCl2 at pH 7.0 for 1hour agitation at

300C) and carbonate (i.e. with NaOAc at pH 5.0 with HOAc for 5 hrs agitation at

300C) occurs at normal condition where as rest are in extreme conditions. In the

normal phase, Fe, Mn and Cr show very negligible percentage of leachability. As

per criteria for risk assessment code (Perin et al, 1985) indicated in Table – 3.12,

results (Table – 3.13) are showing no environment risk with respect to heavy

metal Fe, Mn. and Cr.

3.10 BIODIVERSITY

Orissa contains a great wealth of biological diversity in its forests, its wetlands

and in its marine area. It has varied and wide spread forests harbouring dry

deciduous, moist deciduous forests as well as mangroves with several unique,

endemic, rare and endangered floral and faunal species. Orissa is one of the

richest bio-diversity regions in Southeast Asia.

Keonjhar being a district of Orissa and having a number of reserved forests also

contains large variety of flora and fauna. The area contains different species of

amphibians, reptiles, birds and mammals. A variety of flora species namely

piasal, teak, bija, sisoo, ashan, harida, sidha, mai, char, kumbhi, genduli, salia

bambooetc are found in the area. However, as the lease area doesn‟t contain any

forest land. Hence, no endangered flora or fauna is found in the core zone. The

buffer zone of the area contains reserved forests. A detailed study has been

carried out to have information about the biodiversity of the area, the details of

which have been described in the following paragraphs. From the study it was

found that there is no endangered flora or fauna found over there. The project

being an existing one will not affect the biodiversity of the area. However, it is

proposed to plant local species and medicinal plants during plantation in order to

maintain the biodiversity to some extent.

3.10.1 WILDLIFE CONSERVATION PLAN

There is no National Park, Sanctuary, Bio-sphere reserve, Wildlife corridor,

tiger/elephant reserve existing within 10 Km of the mine lease. Map showing

Wildlife Sanctuary and Wildlife reserves and national parks duly authenticated

by DFO-cum-Wildlife Warden, Bonai is given in Fig.3.5. As per the study no

endangered or Schedule – I faunas are found in this region.

It is proposed to have a wildlife conservation system in the mines and periphery.

For the purpose of wildlife management on corpus fund, alternate cropping, solar

lighting to prevent plant loss, awareness and eco-development measures will be

undertaken. It also includes management on protection of forests, prevention of

forest fire, prevention of poaching, soil and moisture conservation, roads

(minimize the approach road by utilizing only one road), blasting (only in the

fixed time, the afternoon), preventing fall of animals in mine pits by fencing the

boundary of the mining pits, lighting, dust and awareness.

3.10.2 FOREST AREA

There is no forest within the ML area. However, the study area does have several

categories of forest land. The area does not harbor any rare or endangered plant

species.

Fig: 3- 8: Forest map of study area

3.10.3 FLORA

Vegetation near the site is sparse and dominated by annual weeds. The entire area

is mostly open with very few trees, shrubs and few scattered patches of forests.

Shrubby vegetation is noted along the road margins of the croplands. Typical

plant species available in the study area, listed below in Table 3.15 is

authenticated by DFO.

CHAPTER 4

ANTICIPATED ENVIRONMENTAL IMPACTS & MITIGATION

4.0 INTRODUCTION

While providing essential minerals for the use in our economies, uncontrolled

mining can also have many adverse impacts on the environment and human

health. Potential impacts include air and water pollution, mine waste disposal and

land degradation. Hence, environmental impact assessment is essential for the

present environmental scenario.

The project activities as discussed in Chapter–2 have certain effects on various

environmental domains that exist in the area. A scientific assessment of these

impacts those are likely to influence the existing environmental scenario is

needed. This could also facilitate in formulating a suitable environmental

management plan depicting all mitigation measures. It can help in implementing

the project in an eco-friendly manner. The project activities influencing the

following environmental attributes have been studied and their impacts on the

following attributes have been assessed.

Land use pattern

Air Quality

Noise Quality

Water Quality

Ecological Condition

Socio-Economic Condition

The mining and allied activities in the proposed project area have influence on

environmental attributes. These attributes include:

Excavation

Construction of approach and haulage road

Drilling and Blasting

Loading and Transportation

Processing and Sizing of ores

Disposal of overburden/waste etc.

Stocking of low grade ores.

Site preparation




Pag

e87

The magnitude of the proposed mining activity being small is not likely to create

any serious impacts on the existing environmental set up of the area. However,

the likely impacts of the proposed mining and allied activities on the various

environmental parameters are discussed.

4.1 IMPACT ON LAND USE PATTERN

The ML being an existing one won‟t have much further impact on the

degradation of vegetation. The ML has both forest and non-forest category of

land. However, not much of the forest land is or shall be utilized for mining

activities till the conceptual period. During the conceptual period the total

degraded area in forest and non- forest land will be as follows.

4.2 IMPACT ON AIR QUALITY

The dust generated from mining activities is the primary source of air pollution.

The emission sources include excavation and mining of ore bodies, drilling,

blasting, screening/sizing and transportation within the project area. During air

quality monitoring it is observed that dust generation is of short term and settle




Pag

e88

quickly within close ranges. There is very less scope of spreading of dust

particles to the nearby residential areas as these operations are carried out at far

off distances from the habitation areas. Hence, human population is not directly

affected by the air pollution as the impact of dust generation. It is found that the

dust nuisance is not a problem due to deployment of water tankers with sprinklers

and keeps the haulage road surface wet resulting suppressed dust particles. It is

also observed that the dust nuisance is localized i.e. within the project area only.

Negligible amount of auto exhaust emissions also expected to found in the core

zone because of vehicular activities arising due to transportation of ores and

waste by dumpers and excavators closed by. However, there will be very little

impact on air quality due to automobiles. By plying more tipper dust shall be

generated from the road.

The prediction modeling has been carried out by using ISCST Method (Breeze

Soft ware) and with the proposed production target the predicted Ground Level

Concentration of Suspended Particulate Matter shall increase maximum upto

57.494Microgram per cubic meter at a distance of 1km in the south of the lease,

the resultant of which will be well within the prescribed limits.

Source Emission modelling

Air Quality Model

The impacts on air environment from the plant depends on various factors like

production capacity, plant configuration, process technology involved, type of

raw material used, type of fuel used, in plant control measures adopted and

operation and maintenance of the various units of the plant. Apart from these,

there will be other activities associated e.g., transportation of raw material and

finished products, storage facilities and material handling within plant premises

which may contribute to air pollution.

The cement Plant will affect the air quality parameters like PM, SO2, NOx and

CO. The other downstream units will emit dust and fumes. Apart from the above

there will be fugitive dust emissions due to transportation, storage and processing

of huge amount of ores and minerals raw materials. Needless to say the adequate

air pollution control measures will be taken up both at design and operational

stage to confirm the emission parameters within the standard limit.

The impact on air quality due to emission from a single source or group of

sources is evaluated by use of mathematical models. When the air pollutants

enter into the atmosphere, they transport and diffuse in the atmosphere resulting

in pollutant dilution. Air meteorology is the important factor in pollution status

evaluation. The air quality models are designed to simulate these processes

mathematically, and relate emission of primary pollutants to the resulting down-




Pag

e89

wind direction. The model inputs are emission load and nature, meteorology and

topographic features.

4.2.1 INDUSTRIAL SOURCE COMPLEX SHORT –TERM (ISCST3) MODEL

The ISCST3 model is the most widely used model due its ability to handle both

flat and complex terrain, both point and non-point sources and its acceptance by

regulatory agencies. This model is a steady state Gaussian dispersion model. This

model is approved by USEPA (United States Environmental Protection Agency).

This model is also recognized by CPCB (Central Pollution Control Board) and

MoEF (Ministry of Environment and Forest). The complete equation for

Gaussian Dispersion Modeling is given below.

4.3 IMPACT ON NOISE QUALITY

As mentioned in Chapter-2 the proposed mining will be open cast semi

mechanized method. In this open cast semi-mechanized mining the various

sources of noise in the area are attributable mainly due to drilling, blasting,

operation of compressor, loading and haulage, operation of diesel pump and

vehicular traffic.

The operation will be done in single shift of eight hours duration. The various

sources of noise mentioned above shall only be periodical and is limited to a

fixed period of operation only. In addition to this, the transportation of ores might

cause a little effect on the noise level. The noise level result due to such

operations in the active working zones in the area do not indicate any serious

concern as it is well below in prescribed standard limit. All the instruments will

be taken care properly so as to maintain the noise level to the prescribed limit.

The various noise levels and their potential effects on the human being are noted

(Table 4.1). The ambient noise level data (Table 3.6) of the area on comparison

with the possible health hazards due to noise level (Table 4.1), it can be

concluded that there is no serious alarming effect due to mining.

4.4 IMPACT ON WATER QUALITY

Water is one of the most precious resources on the earth. There is a first order

stream flowing in the south-west corner of the ML. There will be a safety

distance of about 50m will be maintained from the stream, so that the impact of

the mining operation on the River will be minimum. And the will be discharged

to the River Baitarani after adequate treatment. Hence hydrology of the area will

not be affected to a great extent and diversion will not be required. The source of

water in the project area is from dug wells for domestic activities and for mining

activities seasonal nala flowing adjacent to the lease hold area will be utilized.

Dust suppression is being done by water spraying through water sprinkler limited

to haulage road and dumping area only. Rainwater flowing through the exposed

mine cuts would carry some sediments of laterite. These are found to be non-

toxic in nature. Surface runoff water from mines has only high turbidity during

monsoon. As discussed, the mining activity will require less quantity of water in

comparison to the recharging. Hence, it will not affect the water regime of the

area. Quarry water shall be treated before releasing to natural drainage system.

Working benches will be kept free from loose overburden/ waste materials and

maintained in a very slant manner so as to allow the surface run-off to flow out of

the working area. Retaining wall will be constructed around the dump to prevent

washing up of the loose sediments. Surface runoff will be properly diverted in to

the original channel of flow beyond the quarry limit. This flowing water will be

kept free of any contamination. Hence the surface water will not be affected to

larger extent. The drainage from the area will be minimal.

As discussed in chapter–3 the annual ground water recharge will be 14.806 Ham.

For facilitating mining and allied activities water requirement will be 100m3 per

day and is proposed to meet from surface watercourse. However, ground water

discharge will increase as the mining work will loose the ground level. Water

requirement for the area is given in Figure 4.2.




Pag

e98

It is further noted that, due to excavation of hard rock the filtration rate will

increase. So, due to mining the ground water recharge will increase as

requirement of water is very small in comparison to the availability and ground

water recharge. Hence, on ground water impact will be marginal.

The lease area falls in hilly region. The ground water table is available at 460m.

With progress of mine depthward, ground water shall cause problems both in the

North Block & South Block. So, it is proposed to be pumped into the duct that

provideslinkage to the link channels constructed for surface water drainage.

Hence, the working will not touch the ground water table.

In case of deeping of mines beyond 460 mRL, Dewatering of the mines shall run

as a regular feature. So, pumping shall be made to nearest reservoir depending

upon the situational demand.

The water table remains below the quarry floor (not yet touched) in Iron Ore

portion. But in Chudia Mn. Pit water percolation has started. So ground quarry

dewatering shall be done for Mn. At the NW corner of the block just south of the




Pag

e99

perennial Nala a Deep Settling Tank over (70m x 60m) area is under making into

which witer from that pit shall be siphoned which in turn shall be drained in to

the perennial nala so that direct discharge is avoided and pollution controlled.

By way of safety zone, a 15m strip has been left on both sides of the perennial

nala passing across the lease so that nala is not physically distorted.

4.5 IMPACT ON TRANSPORT INFRASTRUCTURE

As this is an existing mine, the pollution due to plying of tippers for

transportation of ore will not increase in a large amount. More tippers will ply

after expansion of the mine. Two to three times water sprinkling will be done to

minimize the impact of the pollution. Regular maintenance of the road will be

done in order to make it capable to handle the load.

4.6 IMPACT ON ECOLOGICAL CONDITIONS

The proposed of mining operation shall have little impact on the existing

ecological conditions, as the project area is already broken-up to some extent.

The additional area required to be diverted for mining is having very less

vegetation cover. Afforestation has already been done in some un-worked area as

well as back filled mined out area and re-handled existing dump of the lease. The

nalla flowing within the ML will be remain untouched since it is located in the

non-mineralized zone.

4.7 IMPACT ON HEALTH OF THE LOCAL POPULATION

Due to mining operation pollution will occur due to air, water and noise. All

these parameters may have some impact on the health of mine workers like

asthma, bronchitis, respiratory problems, problem in lungs etc. However, it can

be mitigated by regular water sprinkling and provision of personal protective

equipments for the employees. The project being small won‟t have major impact

on the health of local population. The dust due to transportation will be

suppressed by 3 to 4 times water sprinkling of the roads. Plantation will be taken

care of.

4.8 IMPACT ON SOCIO-ECONOMIC CONDITIONS

The proposed enhancement activities of the project shall have major beneficial

and more or less negligible adverse impacts on the following domains.

4.8.1 EMPLOYMENT

Priority will be given to local people according to their qualification for

employment. The project will contribute direct employment scope for about 349




Pag

e10

0

persons including skilled, semi-skilled and un-skilled mine workers, crushing

plant labourers, supervisory staffs, mining engineers, mechanical engineer,

geologists and surveyors. The project will also generate some indirect

employment for the locality.

4.8.2 EDUCATION

The project activities shall create awareness with the local people for preferring

permanent services than periodical agricultural activities. The activities will help

them to analyse the importance of education. With the increased amount of

income people can send their children to nearby schools. The implementation of

this project shall naturally augment the education status of the local people. These

schools are taking care of the local students in their study. But the Project

proponent has decided to improve the literacy level of the local peoples with the

elders also.

4.8.3 COMMUNICATION

The lease area is approachable from Joda(Town as well as Railway station) at

distance of 5 kms towards West from the site. Nearest Highway is SH or NH-23

distance of 5kms towards west from the site.Nearest air port is at Bhubaneswar

and Port at Paradeep. Implementation of this mining project shall definitely add

to the existing communication facilities.

4.9 SCOOPING PROCESS

As it is evident, due to mining activities the environment of the area in respect of

air and land use shall be adversely affected. Due to activities like drilling,

blasting and transportation shall have affected the air environment of the area.

The SPM level shall go up.

It is also noted that due to the proposed activity forest land shall be degraded with

cutting of tree species cause degradation of floral environment of the area. In

order to mitigate the above adverse effect project proponent has to take required

steps to minimize the affect. Adverse effect in respect of air shall be mitigated by

Construction of well compacted roads.

Regular water spraying on roads and waste dumps by tankers.

Provision of dust collectors for the drilling machines

Controlled blasting

Supply of dust masks for the drill operators

Plantation of wide leaf trees, creepers, tall grasses around quarry sites,

waste dumps, roads, colony and other surrounding barren zones.




Pag

Land degradation affect shall be mitigated by proper plantation programme and

reclamation programme.

4.10 MITIGATION MEASURES :

The various mitigation measures, covering both physical as well as socio-

economic factors, to analyzing the adverse environmental impacts are proposed

to be taken up for the following environmental components.

Degradation of land/soil

Degradation of natural vegetation cover/forest

Pollution of air

Noise pollution

Disturbance of habitat

Disposal and management of waste

5.1 ENVIRONMENT MONITORING PROGRAMME

The monitoring of various environmental parameters is necessary which is a part

and a parcel of the environmental protection measures. Monitoring is as

important as that of control of pollution since the efficiency of control measures

can only be determined by monitoring. Hence, an environmental monitoring cell

will be formed for regular environmental assessment on air, water, noise and soil

qualities at nearby area in and around the ML area. Four permanent Air quality

stations will be fixed as per the SPCB guidance to monitor the AAQ in quarterly

basis. Quarterly water samples of ground water and surface water shall be

collected and analysed. Noise level monitoring at Noise generating points and

AAQ locations shall be done in quarterly basis.

5.2 ENVIRONMENT MANAGEMENT CELL

To implement the EMP, a structured environment cell (EMC) will be present.

EMC undertakes regular monitoring of the proposed pollution control system and

conduct half yearly audit of the environmental performance of the system. It will

also check that the stipulated measures are being satisfactorily implemented and

operated. All the above observations will be complied and documented by the

EMC to serve the following purposes.

i) Identification of any environmental problem, which may occur in or

surrounding area.

ii) Initiating or providing solutions to those problems through designated

channels and verification of the implementation status.

iii) Suitably respond to emerge situations. Provide details of the emergency

action and the action taken to the top management.

iv) Suitably make modifications to alteration in the plant to meet regulatory

standards as amended from time to time.

The entire ML area coming under non-forest area.

Four monitoring station for monitoring of PM10, PM2.5, SO2 ,NOx &

CO have been established..

There is no workshop within the lease hold area. For collection of rain

water during monsoon, we have made arrangement in such a way that

it will be accumulated within the ML area.

Periodical medical examination to all categories of employees is being

done and they are provided with protective devices.

Separate ledger has been made to keep the Acts of Environment

Management Cell.

6.3 EMPLOYEE WELFARE ACTIVITIES

Welfare includes anything that is done for the comfort and improvement of

employees and is provided over and above the wages. Welfare helps in keeping

the morale and motivation of the employees high so as to retain the employees

for longer duration.

The lessee has been conscious about the welfare of his employees to create

efficient, healthy, loyal and satisfied labor force. He has taken care for

monitoring of working conditions, creation of harmony through infrastructure for

health and insurance against disease, accident for the workers and their families.

The lessee is also very much concern for improvement of intellectual, cultural

and material conditions of living of the workers. Some of the existing facilities

are :-

6.4 CORPORATE SOCIAL RESPONSIBILITY (CSR)

For social sustainability of any project, attentions need to be paid to the

development of the society that existed before or builds up around the project

area. The Corporate Social Responsibility is the internalization by the country of

the social and environmental effect of its operations through proactive pollution

prevention and social impact assessment so that it is anticipated and avoided and

benefits are optimized.

The concept is about companies seizing opportunities and targeting capabilities

that they have built up for competitive advantages to contribute to sustainable

development goals in ways that go beyond traditional responsibilities to

shareholders, employees and the law. It is the active partnership of the company

which defines the voluntary works with local communities as well as with

regional and national Government and reciprocity based on trust and openness to

reach agreed objectives and shared involvement. The development activities for

the locality have been taken by the lessee for the locality is as follows.

Employment:

The best method to improve the living standard of any the area is to provide

employment for the locality. The lessee has always followed this principle and




Pag

will do the same in future as well. 80% of workers(un-skilled, semi skilled and

skilled) engaged in the mine belong to local villages The lessee also proposes for

maximum appointment of local people to fulfill the manpower requirement for

this expansion proposal.

Education :

A strong promoter of basic and primary education has been adopted for

educational institutions to enhance their education standards and equip them with

better infrastructure facilities. Financial help to schools in tribal villages and slum

areas, sponsored funds for school building, teachers‟ salaries, books, school

uniforms and other study materials has been done. Many computers have also

been donated to Government schools and schools in rural remote areas promoting

computer literacy.

Community Development:

Being committed and socially responsible, the objective of the Lessee is

community development. Providing villages with basic amenities, and extending

friendship to senior citizens, orphans and physically challenged people are few

initiatives taken in the direction of community development.

Healthcare:

The objective is to provide basic healthcare facilities and a better quality of life to

people in the lower rung of the ladder. As a part of the healthcare program,

hospitals and foundations of the area are supported by the lessee, and also

promotion and assistance to the Government of India initiatives like Pulse Polio

drive has been provided. Some instances include:

Arranging health camps, free medicine distribution, eye check up camp,

mobile ambulance and doctor facility etc.

Providing medical kits to villages along with basic first-aid training

Organising blood donation drives for well-known blood banks

Organising a Cancer Screening in coordination with a renowned medical

foundation

Extending support to the leprosy affected people through micro-financing

and providing sewing machines and utensils to Leprosy homes

Environmental Awareness:

The lessee plays a conscious and active role to improve the quality of life around

us. A variety of campaigns have been initiated towards environmental causes

including awareness sessions for employees on issues like global warming,

environment day celebration through pamphlet distribution and planting of

saplings and other environmental awareness campaigns across our locations.

He also actively participates in relief programs and campaigns during natural

calamities and disasters. With contribution and support of its employees and

government, he had provided quick relief and support to the affected areas by

participating in relief programs, donation drives etc.

Other Peripheral Development Activities:

Development of infrastructure facility is one of the main activity in CSR domain.

Water supply, road construction and maintenance bridge construction etc. are

main infrastructure for any area. The project proponent is also involved in the

development of all these activities.

Thus the lessee, being a responsible citizen, has tried for the development of the

area by various beneficial activities. The lessee intends to continue the same in

future as well. The details of cost details for welfare activities already under taken

Due to the mining activity of all these mines, there will be some impact on the

environment. However, those impacts can be mitigated by proper control

measure like regular water sprinkling, maintenance of haul roads as well as roads

connecting the mines and machineries and adequate plantation. The lessees being

concern about the environment have come together for a joint collaboration to

discuss the problems that may arise due to the mining activity and take necessary

measures to mitigate them.

6.6 RISK ASSESSMENT

Human health and Environmental risk from developmental activities is mainly

due to occurrence of some accident consisting of an event or sequence of events

explosion, fire and toxic hazards. Risk analysis provides a numerical measure of

the risk that a particular facility poses to the public. It begins with the

identification of probable hazardous events at an operational area and

categorization as per the predetermined criteria. The consequences of major

events or accidents are calculated for different combinations of weather

conditions to stimulate worst possible scenario. These predictions of

consequences are combined to provide numerical measures of the risk for the

entire facility. Risk assessment should be done on the basis of past accident

analysis at similar projects, previous judgments and expertise in the field of risk

analysis especially in accident analysis.

CHAPTER 8


8.0 INTRODUCTION

A detailed account of the impacts on the environment due to the proposed mining

activities in the lease area has been discussed in Chapter–4. It is evident that the

proposed activities will have marginal impact on different environmental

components. To mitigate such adverse impacts, negligible though, appropriate

remedial measures have been proposed, the details of which are being discussed

in this chapter.

8.1 OBJECTIVE OF THE EMP

Keeping the above considerations in view, the EMP aims at achieving the

following objectives.

Sustainable mineral development

Least damages to the existing environmental domains

Evaluation of environmental impacts due to proposed activities

8.2 BASIS OF EMP

The formulation of EMP is based on the following considerations.

Evaluation of proposed project activities

Studies on Environmental Impact Assessment for the project

8.3 MITIGATION MEASURES

For maintaining better environment in the area the components relevant to the

project that need to be taken into account include.

a) An afforestation/plantation detail of plantation/afforestation programme

under taken by the lease is given below.

b) Reclamation of degraded quarry area

c) Construction of check dam, boulder pitching of bench edges, hauls roads

etc.

d) Monitoring of environmental parameters.

On completion of mining activities the degraded land covered under mining shall

be restored through backfilling of solid waste removed and stacked. Each non-

working bench is proposed to be stabilized by boulder pitching and plantation of

shrubs to arrest free movement of loose materials. Waste dumps will be

rehandled to some extent, then stabilized, graded and compacted. This shall be

provided with peripheral check dams and garland drains to control the movement

of loose materials. Dump yards shall be rehandled and shall be planted with local

tree species. During the 1st five years, it is proposed to stabilize the existing dump

over 1.1ha of area and maintain plantation over there. As estimated, about 79.314

ha of land will be planted during life of the mine @ 2000 no of saplings per ha.

Thus about 158628 number of sapling will be required for this purpose.

5,54,758m3

of waste will be used for back filling of mined out area.

8.3.2 PROGRAMME OF PLANTATION

The plantation area will not require any extensive soil preparation as the original

soil cover will not be much disturbed. However, in the reclaimed area, suitable

nutrients may be added for proper growth of plants if required.

Post plantation care includes replacement of casualties, weeding, soil working,

manuring, watering, protection from grazing and fire, engaging watch and ward

staff. This scheme and selection of plant species are mainly based on the local

soil conditions. A few species are listed below for plantation programme. As

programmed, more number of trees and vegetation will be grown during the lease

period which will be effective on the protection of environment and aesthetic

beauty of the area. The forests over the dump when fully developed will give a

positive impact on climate. The terrace formation will give better land scaping.




Pag

The plantation along the boundary, along the roads, around quarry area etc. will

help to develop much improved landscape.

Proposals are being made to systematically and scientifically reclaim and

stabilize the exhausted quarry area. The scheme of reclamation and afforestation

has been proposed which shall be implemented after 4th

year of operation. The

detail year wise schedule of phase reclamation and plantation is given as follows.

(Table No.10.1, 10.2 and 10.3).

area will be coved under plantation which is about 70% of the total area.

Since there is not much non-mineralized zone for the lease area, it is not possible

to have a plantation over 33% area from the initial stages. However there will be

plantation over 70% of area after the mine life.

Beside reclamation plantation the safety zone area shall be covered under

plantation programme with the observation and charge of state forest department.

8.3.3 MEASURES FOR CONTROLLING WATER POLLUTION

The surface run-off during rainy season the main source of water pollution. The

measures proposed for runoff management are as follows :

No overburden or loose sediments will be kept in the working

benches particularly during monsoon months.

Check dam will be provided around the temporary overburden

storing sites to arrest flow of loose sediments before discharge into

the drainage system of the region.

Peripheral drain proposed to arrest the inflow of run-off water to

the quarry area.




Pag

e12

9

The surface runoff water shall kept within the lease area as

maximum as possible.

Settling pits shall be formed in the rainy season.

The settling pits shall work as water harvesting structure as well as

water conservation measures.

In rainy season the rain water flowing through the lease area will

be channelized to settling tank for settling it will be used for

mining operation, plantation, and water sprinkling as well as for

watering of nearby vegetation through canals. Thus rain water

harvesting of the area will be done.

The possibility of the project activity contributing to the pollution of water

courses of the region or to the ground water regime is so less that this does not

significantly constitute an area of concern.

8.3.4 MEASURES FOR CONTROLLING AIR POLLUTION

The mining area, due to its very nature and scale of operation is likely to

marginally contribute towards air pollution in the area. The effect is localised and

this effect is mostly due to fugitive emission. For the mine, the only pollution

occurs from dust (SPM) during vehicular traffic, blasting, loading/unloading etc.

As the particles are heavy in nature, they settle easily in the immediate vicinity.

There is no other source for SO2, NOx and CO except a little contributed by the

vehicular traffic, which is well below the prescribed limits. Still, the following

different control measures are proposed.

Construction of well compacted roads.

Regular water spraying on roads and waste dumps by tankers.

Provision of dust collectors for the drilling machines

Controlled blasting

Supply of dust masks for the drill operators

Plantation of wide leaf trees, creepers, tall grasses around quarry

sites, waste dumps, roads, colony and other surrounding barren

zones.




Pag

8.3.5 MEASURES FOR CONTROLLING NOISE POLLUTION

The sources and causes of noise have been discussed in Chapter-3 and its

negligible impact has been highlighted in Chapter-4. However, the following

measures will be taken to minimize the adverse impact of noise, though

negligible within the project area and its surrounding region.

Proper and regular maintenance of vehicles, compressors and jack

hammers.

Provision of supplying ear plugs for jackhammer drillers and compressor

operators.

Carrying of blasting only during daytime not during cloudy weather as

well as and when strong wind is blowing towards residential areas.

Blasting will be carried out with limited explosives at a time so that the

noise generation can be well maintained with the prescribed limits.

Provision of Green Belt (thick foliage) along the lease boundary and road.

8.3.6 SOCIO-ECONOMIC MEASURES

Apart from overall beneficial impact of the project on the local people of the

region, it is felt necessary to augment facilities in the fields of education, health

and social awareness including concern for ecology. These are presented as

follows.

Sl. No. Environmental Attributes Nature of Impact

1 Employment Beneficial

2 Service, trade/commerce - do -

3 Public utility/education, social awareness Augmentation

4 Health care facilities - do -

It is necessary to create awareness among the population the beneficial aspects of

the following measures which would be taken up by the mine as a periphery

development project.

Family planning

Abandonment of shift cultivation

Planting of trees and social forestry

Reduction in the consumption of fuel wood and encourage

use of alternative fuels

Use of clean and boiled water

Reducing the consumption of alcohol

Saving from earnings

Personal hygiene

Regular health check

In implementation of these measures, the mine management can contribute lot on

the overall socioeconomic scenario of the region.

8.3.7 SAFETY MEASURES DURING BLASTING

Controlled blasting practices will be adopted to minimize the ground vibration,

sound and fling particles. Before blasting all the entrances to mines will be

guarded by persons and red flag will be posted to check inadvertent assess to

blasting zone. Sufficient warning systems by sirening or whistling will be made

before blasting to make persons alert. Sign boards will be posted at convenient

places where time of blasting operation and blasting danger zone to be indicated.

Shallow hole blasting will be carried out on to dislodge the boulders proper

charging, stemming and muffle blasting has been proposed against fly rock

hazards.

8.3.8 SAFETY & OCCUPATIONAL HEALTH

Since, the proposed mining is proposed to be operated by semi mechanized methods

deploying man and machines, it is envisaged to take up the following precautionary

measures.

Strict observance of the provisions of Acts, Rules and Regulations in respect

of safety both by management and the workers.

Proper planning and designing of work in order to reduce the risk of hazards.

Specific instructions and supervisions of working where danger due to fall of

side (overhanging, undercutting of bench, fall of objects from higher

benches/places, working at height is apprehended).

Training of work persons & the officials.




Pag

Parapet walls have been constructed on the sides of the haul road to prevent

fall of vehicles. The width of road will be maintained more than thrice the

width of the vehicle. A code of traffic rules will be implemented.

A code of practices for tipping in stock piles/dumping of overburden at dump

yard and loading point will be implemented.

In respect of contract work, safety code for contractors and workers will be

implemented. They will be allowed to work under strict supervision of

statutory person/officials only after they will imparted training at vocational

training centres. All personal protective equipments will be supplied to them.

A code of practice for fighting fire will be implemented.

Competent persons like fitters, mechanics will imparted with special attention

to the safe handling of materials while attending to repairs, maintenance of

HEMM.

8.5 IMPLEMENTATION AND MONITORING

As the major attributes of environment are not confined to the project area alone,

implementation of the proposed control measures and monitoring thereof have to

be undertaken on a regional basis. The mine management will, however,

implement the control measures and monitor the efficacy within the lease area

relating to the following specific areas as per the action plan.

Collection of air and water samples at strategic locations with appropriate

frequency and testing there of. If the parameters exceed the permissible

tolerance limits, corrective measures should be taken to arrest the

pollution.

Collection of soil samples at strategic location at least once in every year

and testing there of with regards to deleterious constitutions, if any.

Desiltation of drainage system and check dams.

Measurement of water level fluctuation in the near by dug wells and

borewells periodically.

Plantation/afforestation as per programme, regular watering of plant and

fencing to protect them from cattle/goats.

8.6 IMPROVEMENTS IN THE PHYSICAL INFRASTRUCTURE

The development of mining and industrial projects plays a key role in economic

growth by generating employment both directly, indirectly and development of

downstream industries. Peripheral development of the area takes place and due to

more influx of money through the populace, overall importance of the area

increases and the infrastructure improves.

From the very inception, the lessee of Inganijharan Iron & Manganese ore mine

is aware of and is concerned about the health safety of not only of its own

employees and their families but also about the ecology and issues affecting

society around the mine. As a corporate citizen, it always has been the endeavor

of group to take effective steps to tackle all these issues. Following improvements

in the physical infrastructure are envisaged.

Condition of roads. The transportation of the minerals will be by

mainly by road to rail head. The lease area is approachable from

Joda (Town as well as Railway station) at distance of 5 kms

towards West from the site.

Condition of educational buildings. The lessee will aid in

construction/maintenance of school buildings in the nearby

villages.

Condition of housing facilities. As the persons engaged for

outside will reside in the leased / rented houses in the nearby
