Nature has gifted Odisha with vast and extensive mineral resources. Mining of

minerals and extraction of metals were in practice in ancient Odisha. After independence,

rapid growths of mining activities in the state mining activities have depleted resources of

many deposits, new findings have also added to it. Graphite mining is an important activity

in Odisha. However, the enhanced mining activity is adversely affecting the environment.

For the past few decades, areas in and around the mining activities are getting affected by

the progressively increasing pollution load. Mining having adverse impact on natural

resources like land, forest, water, flora and fauna. Side by side, there is generation of solid,

liquid and gaseous refuge polluting air, water, soil and scenic natural beauty. The water

table is being lowered resulting in more dryness, dusty atmosphere, decreasing rainfall with

consequent less growth of vegetation. Now - a - days the growing concern towards the man

& environment has enforced the environmental ethics into the corporate levels. Through

the Environmental Impact Assessment exercise, the anticipated adverse impacts are being

identified and Environmental Management Plan has been formulated to mitigate the

impacts and sustain economic growth in harmony with nature.

1.1 Purpose of the Report

The Environment Impact Assessment and Environmental Management Plan of

Goendamal Graphite deposit address all the environment related issues and is prepared in

accordance with the requirements Ministry of Environment and Forest, Govt. of India, EIA

notification (2006) and subsequent ammendments.

The EIA/EMP report is based on the data generated from March 2011 to May 2011.

The baseline data for one month (April 2014) has been generated by M/s Cleenviron Pvt.

Ltd., Odisha forrevalidation of the EIA report.

The study evaluates the prevailing baseline environmental conditions. The adverse

impacts are identified and possible mitigation plan has been drawn in order to protect the

ecological system.

The present proposal is for enhancement in production of crude graphite from 3500

MT/ annum to 15,000 MT/ annum.

1.3.1 Importance of the Project to Country and Region

Graphite is an important strategic mineral of our country and presently about 2000

tones of finished graphite is being imported every year. It is one of the most important

industrial mineral having multifarious uses because of unique physical and chemical

characters such as high melting point, extreme chemical inertness, good electrical

conductivity, low specific gravity and easy translation. The production of graphite ore in

our country is insufficient to cater the demand of different industries. The beneficiated

graphite ore produce fromGoendamal Graphite Ore mines will cater the raw material

for different industries like refractories, Pencil industries. of the locality.

The proposed project with judicious and satisfactory mining methodologies will bring in

a better standard of living by improving the existing infrastructural facilities, job

opportunities and also the health status of the surrounding areas.

In a larger perspective, it will improve our country’s growth in production of graphite

ore.

2.4.2 Reserves

Reserve of graphite has been re-estimated by cross sectional area method. 15 no.s of

geological cross sectional area i.e. A-A’,B-B’,C-C’,D-D’,E-E’,F-F’,G-G’,H-H’,I-I’,K-K’,L-L’,M-

M’,N-N’ and O-O’ have been drawn for the reserve as shown in Geological plan. The basis

and parameters considered for calculation of reserve for graphite is as follows:

GR = A x L x RF x TF

Where,

GR = Geological reserve in MT

A = Area of cross section (Sq.m)

L = Length of influence (m)

RF = Recovery Factor (%)

TF = Tonnage Factor (MT/Cum)

Mineable reserve has been estimated taking into account mining block due to slope

factor in the same manner as the geological reserve duly providing allowance for the

Graphite that will get blocked under 7.5sq m wide safety zone and under the ultimate pit

slope of the mine. However, the reserve under said blockage is around 15% of the geological

reserve. The updated geological and mineable reserve up to 01.04.2011 is 1699621MT and

1122374 MT respectively. Since 1998 to till 2009-10 total 24728 T of crude graphite has

been exploited from the mine. Based on exposed vein on the quarries and depth confirmed

in the previous bore holes the additional reserve has been estimated in the approved

estimation modification of scheme of mining.

The map showing the geological plan and section has been given as figure 2.3and

figure 2.4. The summary of geological and mineable reserve has been given in table 2.3.

Based on surface geological data excavation will be confined to the existing quarry-5. Due to

labor problem in the locality semi mechanization method of mining is required to achieve

the production target. It is proposed to continue mining operation in the mine by “A” OTFM

method. The height and width of the benches are maintained at 3 and 4 m respectively.

Slopes of the benches are nearly vertical with overall quarry slope at 45º. In the ensuing

scheme period the existing quarry will be developed further to depth and towards south for

raising ore.Manual sorting will be carried out by using equipments like crowbar, pickaxe,

spade, chisel, hand shovel. wherever necessary small capacity poclain (0.9 cum) will be used

for loading and transportation will be done by tippers. The total annual production for the

scheme period is proposed as 15000 MTPA. The excavation planning is confined to the

existing quarry Q-5. Average working days during the year are about 220 days. Average daily

production is about 68 tonnes.

Representative samples drawn from different location and soil profiles have been

analyzed to know the soil characteristics. The analysis has been conducted to note various

(physical & chemical) parameters as per the guidelines.

3.4.7 Socio-economic & Demographic profile

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

on various aspects of socio-economic and demographic profile.

3.4.8 Meteorological Parameters

The monitoring stations at Goendamal were fixed with conventional anemometer to

measure the wind speed and wind vane to note wind direction. In a view to assess the

meteorological parameters of the project area and its surroundings, studies have been

made to generate and compile data on rainfall, wind speed, wind direction, temperature &

relative humidity. 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.

3.4.9 Ecological Status of the area

In order to assess the ecological status of the locality a small population of the area is

selected as a sample, which represents the area. In the present context the floral

composition of the area was studied by random sampling at number of places from a central



28

point taking quadrate as the unit of sampling. The fauna list was collected from the forest

department and local people.

3.4.10 Method for the Quadrate Study: Plot Quadrate Method

Quadrate size was fixed as 1m x 1m, 5m x 5m and 20m x 20m for herbs, shrubs and

trees respectively selected randomly at each study location. The occurrence of trees, shrubs

and herbs species in each quadrate was recorded for further study. This evaluation helps

determining the relative importance of each species in the area and to reveal whether any

economically valuable species is endangered in the process.

3.5 Establishment of Baseline for Valued Environmental Components

3.5.1 Topography

The ML area is located in village Goendamal, P.S-Turekela, of Bolangir district,

Odisha. The area shows gently sloping topography forming a dissected pediment landscape.

The average altitude of the area is 340m above MSL. The area is covered in the Toposheets

No. 64 L/14. This area lies between latitudes of 20° 35’ 00” N and longitude of 82° 46’ 40”E.

3.5.2 Connectivity

The lease area is connected by well developed metalled PWD road from Kantabanjhi

in the east and Lathore in the North. The road passes through the ML area. The G.P road

from Gaoendamal to Kandagada also passes through the lease area. The nearest railway

station is at Harishankar Road at a distance of abour 6 Km from the ML area. Nearest town

is at Kantabanjhi which is well connected to the ML area.

3.5.3.1 Regional Geology

Graphite in these parts of the state is known as “Surmamati” which the local people

use as paint for their houses and earthenware. Graphite deposits occur in association with

Eastern ghat rock types of precambrian age. The area under reference is southern part of

“Sargipalli Graphite Belt” in Sambalpur and Bolangir districts. The area is mostly soil covered

with sporadic outcrops of quartz-garnet-silimanites+graphite schist and gneisses,

granitiferous quartziteand calcium silicate/granuliteof khondalite suit, their migmatised

equivalent and granite-gneiss with pegmatite and quartz veins. Occasional boulders of

pyroxene of charnokite suit of rocks are also at places. The tentative lithography of the

region is given below:

Recent: Alluvium/soil

Laterite

Pegmatite/Quartz veins

Migmatites (Garnetiferous granite gneiss)

Eastern Ghat Group Charnockite: pyroxene granuliteKhondalite:Quartz-garnet

Sillimanite graphite

Gneisses/schist

Garnetiferous Quartzite

Cal-silicate/granulite



31

The general trend of foliation/schistocity in the area is NNE-SSE with gentle (15-40)

easterly dip.

Graphite is flaky and crystalline and occurs as disseminations within quartz-garnet-

biotite-sillimanite-schist/gneiss and constitutes about 1-2% of the rock. The commercial

deposits are confined to graphite schist within khondalite Migmatite. These occur as

enechelon bands or lenses conformable to foliation of the rocks. All the payable Deposits

are emplaced by pegmatite/quartz veins. The presence of such veins enriches the quantity

and quality of the deposits. Normally, these veins intruding into the graphite schist have

concentrated graphite along its margin where good growth of flakes takes places. Graphite

mineralization is also influenced by folding by forming rich concentration at the crustal part

of the fold.

3.5.3.2 Local Geology

Though the ML area is covered by soil & clay, on examination of the local geology in

the areas adjoining the ML area and rock types encountered in the trial pits and boreholes it

is interpreted that in the ML area three narrow bands of Khondalite schist are sandwiched

between Khondalite Migmatite. The overall trend of this schist is N300 S. Dip is around 160 in

the direction of S 600 E.

Graphite occurs either as disseminated flakes or as segregated veins or pockets in

the schist. All along the strike continuity of the schist, the graphite concentration varies

owing to its nature of occurrences and at some places it is concentrated (FC is more that

10% by visual estimates) to become economically viable for exploitation.

3.5.3.3 Studies reveal the local Litho-Stratigraphy as follows.

Soil (Red coloured)

Laterite, Morrum

Pegmatite/Quartz veins

Khondalite Migmatite

Graphite bearing feldspathic schist (Khondalite)

3.5.3.4 Description of Rock Types:

a. Khondalites

It occurs as gneissic and schistose rocks affected by weathering. It consists of Quartz,

Feldspar, Sillimanite, Garnet, Biotite& Graphite. It is medium to coarse grained and grayish

brown in color.



32

b. Granite Gneisses

The exposure of these rocks can be seen in the north of the quarry. It occurs in the

area in patches. It contains fine dots of garnet and hence can be termed as garnetiferous

granite gneisses.

c. Quartz Veins

They are generally found in the fracture zones of older rocks, developed during the

different phases of folding movements. A number of such veins are found exposed in the

quarry.

d. Migmatite

It is a hybrid product of original khondalite in the process of metamorphism. It is

light colored, medium grained rock containing quartz, feldspar, garnet, biotite and graphite.

The pegmatite has intruded into the migmatite and is commonly observed in trial pits

with graphite.

e. Soil

A major part of leasehold area is covered by the soil. In general it is ferruginous in

nature. Occasionally pieces of garnet are found in it. It varies in thickness from 0.5m to

1.5m. On an average its thickness can be taken as one meter of which the top layer of 0.3m

thickness is soft &rich in humus.

3.5.3.5 Graphite Genesis

Graphite occur in a wide variety of rocks such as carbonaceous shales,coil

(sedimentary rocks); basalt,peridotite,nepholin syenite, pegmatite, (igneous rocks);marble,

qrartzite,gneiss,schit,migmatite,(metamorphic rock) and even in meteorites.graphite in

these rock formed under various geological envernment.The genesis of graphit in high grade

metamorphic rocks has been the subject of different interpretation such as granulity facies

metamorphism of carbonaceous matter;reduction of oxider of carbon either emanated

from magnetic sources or due to silicification of limestones ; a direct consequence of

granulity fancies metamorphism in the presence of CO2-rich fluid under low O2 condition;

assimilation of cystal material containing biogenic carbon by magma; and methanation of

carbonate menerals by hydrogen. In the eastern ghats complex of Orissa, the sedimentary

percentage of some graphit are sediments metamorphosed under granulity facies

conditions.Methamorphism of carbonaceous marerial producing graphite is well known

(ubbelodhdf and lewis, 1960; walker, 1969; pacault, 1971).A directrelation exists between

graphitistation and metamorphic grade. The first recognized fully crystalline occurs in rocks



33

of albite-epidote amphibolites and amphiboite fscies where temparture probably exceeded

400oc and pressure ranged from < 2 kb to> 6kb (landis, 1971).many authors belived that

such carbonaceous materials are of biogenic origin (clark, 1921 ;Tilley, 1921;walker, 1962;

Erdosh ,1970 ;Landis, 1971; Pacault, 1971 ; grew , 1974; Dissanayake, 1981; kucha and

wieczorek,1988; senguota and chhattopadhyay,1991). But the biogenic or abiogenic origin

of such carbon need to be confirmed by carbon isotope data (luque et al,1992),as such

carbon could possibly be abiogenic (Eck et al., 1966; karkhanis, 1977).

Graphite can be formed by the reduction of oxides of carbon produced either as a

result of magnetic process or by silicification of limestone (winchell , 1911 , Bastin, 1921 ;

Tilley , 1921; Bain, 1929; Ford, 1954; Strens, 1965 )following reversible reacation.

2CO=CO2+C (Boudouard reaction)

C+2H2O=CO2+2H2

C+H2O=CO+H2

During metamorphic devolation , vest quantities of fluids were developed , and under deep

seated granulity facies they wear rich in CO2 which were later precipitated as graphite under

reduced H2O (Katz, 1987 ; Santosh, 1992).

However , the objection to such reacaction is the very low value of equilibrium constant of

carbon dioxide (Craig, 1954) is consistent with both stability over the whole range of

temperatures of metamorphic reaction and inabillty to dissociate by itself.Reduction to

carbon requires temperature above 800Oc and the presence of V, Zn,Si , Ti,Al, Mg,or Ca as

native which do not exist in the crust (salotti et al., 1971).

Assimilation magma has crystal material containing biogenic carbon by the ultramafic

magma has been advocated as the source for the graphite vein deposit .The process of

mantle derived ultramafic rocks of serrania da Ronda ,southern spain.the process of maxing

of mentle carbon (δ13c=-7 ‰ ) and biogenic carbon (δ13c=-25‰) would explain the carbon

isotopic composition (δ13c=-18‰ to -16.5‰) of the graphit vein deposit (luque et al.,

1992).Isotopic stydy of graphite s from kerala khondalite belt suggests three different

modes of geneiss viz (a)graphite in the gneisses where charnockite formation is absent

showed lowest δ13c values (upto -43 ‰)corresponding to biogenic carbon.(b)samples from

the charnockite lens yielded a range of -14.4 to -12.2 ‰ δ13c values representing mixed

biogenic-fluid controlled .(c) graphits associated with charnockite adjacent to calc –silicate



34

have δ13c in the range of -408 to -9.3 ‰ which have been precipitated from heavier carbon

enriched fluids emanation by decarbonations .relation,1992).

The calc –silicate granulites are considered to be the most probale source of carbon

in the eastern ghats complex of Orissa.methanation of carbonate menaral by hydrogen

takes place at low hydrogen pressure, under 200oC,provided the gases produced (

particularly H2O) leave system or enter into a soild phase. Subsequent pyrolysis of methane

result in the formation of graphite by the reaction CH4→ C +2H2.Once carbon is formed it

would have a catalytic effect on subsequent methane dissociation (salotti et al ,. 1971 ;

Acharya and Dash ,1984).

The field and menaralogical evidences suggest or by CO2-rich fluids generated through

diverse processess (santosh ,1992),if at all ,may be of local and / or minor signification

graphite , after its formation, in solid state through open spaces in rocks to low pressure

sites such as foliation planes, fractures, fold hinges. (Erdosh , 1970). The textural and

microstructral features show graphite as an infilling of a variety of open spaces in rocks and

mineral .The mineral impurities gangue mineral impurities in graphite lodes ,wedges of

gangue mineral withen the cleavage planes of graphite ,branching , step –like margines

,kinks and slips in graphite suggest for its crystalinity (Acharya and Dash ,1984).secondary

manganese and iron minerals like cryptomelane ,psilomelane , lithiophorite,birnessite and

goethite fill the cleavage planes of graphite,replace as well as enclose flakes and tablets of

graphite which suggests that they are later to graphite (Acharya and Rao,1998).

3.5.4 Water Resources

The main drainage pattern of the area is formed by tributaries of Lant river which

flows at a distance of 1.3 km in the north-east of the ML area. Other small nalas flow in NE

to E directions and join Lant River in the North. The drainage pattern is dendritic with

coarse density in the surrounding area. At some places the drainage system is sub-parallel.

There is no seasonal or perennial nala in the lease area.

The drainage map showing the water bodies within the buffer zone of the project

area has been given in figure 3.1.

3.5.5 Geo-hydrology

The entire study area is underlain by rock types of eastern Ghat Super Group of Pre-Cambrian

age. The rocks constitute Khondalite, Charnockite and Granite gneisses. The lateritic

formations occur as cappings at discontinuous patches.

The pre-monsoon depth to water level varies in the range between 5.0m.bgl and 7.0m.bgl.

The post-monsoon depth to water level varies in the range between 2.3m.bgl and

6.7m.bgl.Rainfall is the principal source of ground water recharge in the study are/buffer

zone. For estimation of ground water resources and stage of ground water development in

the buffer zone, GEC (Ground Water Resource Estimation Committee, 1997) norms have

been adopted and are described below.

3.5.5.1 GROUND WATER RECHARGE

a) Monsoon Ground Water Recharge

I) Based on Rainfall Infiltration Method

Total Area : 314 sq.km

Area suitable for recharge : 295sq.km

Average Rainfall : 1534.5 mm

Infiltration factor : 12%

Annual Recharge : 54.30 MCM

II) Based on Water Table Fluctuation Method

Area suitable for recharge : 295 sq.km

Mean water level fluctuation : 3.5m

Specific yield : 4%

Maximum Ground Water Recharge : 41.3 MCM

The ground water resource estimated by Water table fluctuation method is less. Therefore

as per the norms of GEC, it is to be adopted.

b) Recharge through other sources

Recharge through other sources primarily constitutes recharge through surface water

irrigation. Return recharge from surface water irrigation is estimated to be 30% of the

applied water for irrigation. As per the district irrigation department, about 898 ha. Of land



37

is irrigated in the study area. If the gross irrigation requirement is taken as 50 cm/ha, total

applied water will work out to be 449 Ham. The return seepage will be 30% of 449 Ham i.e.

134 ham or 1.34 MCM.

c) Hence annual ground water resources will be

41.3 MCM+1.34 MCM

=42.64 MCM

3.5.5.2 GROUND WATER DRAFT

Ground water is mainly used for domestic, irrigation and industrial need. To estimate the

ground water use, Census data of 2001 have been used for population and irrigated area.

Draft for Drinking Use

Population using groundwater as drinking water : 37635

Per Capita : 70 lit/day

Annual Ground Water Use : 0.00263 MCM

Irrigation Use

About 83 ha of land is being irrigated through ground water. Considering 50 cm/ha of

ground water use, total ground water need for irrigation works out to be 0.415 MCM.

Industrial Use

Several industries are in the process of being set up in the study area. The industrial use can

be taken to be about 3 MCM

Total Ground Water Utilization

0.002MCM+ 0.415 MCM+3 MCM

= 3.417 MCM

Ground Water Balance

Annual Resources =42.64 MCM

Annual Utilisation =3.417 MCM

Balance GW=39.223 MCM

3.5.5.3 STAGE OF GROUND WATER DEVELOPMENT

The stage of ground water development in an area is taken as the ratio of Gross annual draft

for all uses to the total utilizable ground water resource or net annual ground water

availability

Thus the stage of ground water development ( in %) in the buffer zone is8.01 %



38

Since the buffer zone represents an area where stage of development is 8.01 % and there is

no long term decline of pre & post monsoon water level , the area is categorized as safe.

3.6 Land Use Pattern

The landuse / landcover classification system standardized by Department of Space,

for mapping different agro-climatic zones has been adopted. This classification system has

six major land use classes at level I and twenty-eight at level II (table 3.4). The land use

classification of the buffer zone of the study point is shown in table -3.5. andfigure-3.2.

3.7 Traffic DensityThe traffic density monitoring stations was located on Kantabanjhi – Harishankar

PWD road near Goendamal village.

3.7.1 ObjectiveObjective of the study was to measure traffic volumes and note other related traffic

characteristics such as flow composition, flow fluctuations.

3.7.2 MethodologyManual Classified Count (MCC) method was used to count the number of vehicles

passing through a given point and classify them according to vehicle type (e.g. Heavy Goods

vehicles, cars, motorbikes). Manual Classified Turning Count (MCTC) – was used to count the

number of vehicles passing through intersections and classify the vehicles according to type

(e.g. cars, motorbikes).

Traffic density measurements were done continuously for 24 hours by visual

observations and counting of vehicles under various categories. The time period chosen

from 7:00 a.m. to 9:00 a.m., included the morning peak flow. Two skilled persons were

deployed simultaneously during each shift – one person on each of the two directions for

counting the traffic. A summary of the traffic density monitored during survey period is

given table 3.6.

The peak traffic density was attained during 8 to 9 am during day time and 5 to 6 pm

during the evening. Contribution of heavy vehicle to the total traffic is 8 % only. 21% of



42

traffic is contributed by Car/Jeep/Van/Auto and two wheelers. This may be due to the traffic

inputs from near by habitation.

3.8 Climate and Meteorological Parameters

The major part of the district falls under the agroclimatic zone of Western central

table land. The climate is hot and moist sub-humid with a dry period during the winter

season from October to March and a wet period from mid-June to mid- September when

over 80% of rainfall occurs. The district experiences large amount of humidity all along the

year. The average temperature during the summer months is about 38°C and in winters the

temperature drops to about 14°C.

The rainfall in the area is mostly because of south – west monsoon. The annual

average rainfall of about 1384 mm occurs during the monsoon period and the average

number of rainy days is around 70. The climate is characterized by high inter-annual

variability. Temperatures vary according to altitude and are highest in May (up to 47°C) and

lowest in January (down to 12°C).

3.8.1 Methodology

The methodology adopted for monitoring surface observation is as per the standard

norms laid down by Bureau of Indian Standards (IS: 8829) and India Meteorological

Department (IMD). On-site monitoring was undertaken for various meteorological variables

in order to generate the site-specific data.

The Central Monitoring Station (CMS) equipped with continuous monitoring

equipment was installed at a height of 10 m above ground level to record wind speed &

direction, relative humidity and temperature. The meteorological monitoring station was

located in such a way that it is free from any obstructions and as per the guidelines specified

under IS: 8829. Cloud cover was recorded by visual observation.

Secondary information on meteorological conditions has been collected from the

nearest IMD station at Bolangir and Bhubaneswar.

3.8.2 Temperature

Both the night & day temperatures increase rapidly during the summer season from

March to May. The maximum temperature of the district is during the month of May i.e.

around 47°C and minimum during January i.e 12° C. The monthly average temperature

during the period of 2000 to 2009 has been furnished in table 3.7 and graphical

representations of the same have been given in figure 3.4.

3.11 Ambient Air Quality

The study area includes mostly villages and open areas. Ambient air quality

monitoring was carried out at eight locations within 10 Kms radius including AAQMS in

downwind direction. The results are tabulated below. This section describes the selection of

sampling locations, methodology adopted for sampling, analytical techniques and frequency

of sampling for ambient air quality monitoring. The existing ambient air quality in terms of

Particulate Matter (PM10), Sulphur Dioxide (SO2) and Oxides of Nitrogen (NOX) has been

measured through a planned field monitoring. Ambient Air quality-sampling stations are as

shown in figure 3.8.

3.11.1 Frequency & Duration of Sampling

Ambient air quality monitoring was carried out at a frequency of two days per week

at each location during the study period continuously for twenty four hours.

3.11.2 Method of Sampling

Air monitoring stations sampling was done at 8 sampling locations at a height of 3

meter above the ground on a platform erected with outcrops at the base. The station

represents approximately the highest ground level of the area and practically having no

obstruction. Respirable Dust Samplers have been used for monitoring PM10 and gaseous

pollutants like SO2 and NOx.

The result obtained was compared with standards recommended for ambient air

quality. The comparison reveals that the ambient air quality study results are well within the

stipulated limits. The summarized AAQ monitoring result is given in table 3.14 (a). The

chemical characteristaion of particulate matter is given in table 3.14 (b).The details are

being presented in Annexure 3. The National ambient air quality standards are presented in

(i) Chemical Characterization of NRPM and RSPM

The physicochemical characterization of the NRPM & RSPM reveals that liquid

absorbed by soluble species forms a major component and exceeds 70%, but much of this

evaporates when filters are equilibrated prior to weighing. The inorganic elemental

compositions of the fine particles were dominated by Silica, Iron, Calcium, Aluminium and

Manganese, with minor amounts of potassium, chlorine, sulfur, sodium and zinc. The

chemical composition of the particulate matter is being given in table 3.14 (b).

3.13 Soil Quality

It is essential to determine the potential quality of soil in the area to identify the

current impacts of urbanization and industrialization on soil quality and also predict impacts,

which may arise due to the project operations. Accordingly, a study of assessment of the

baseline soil quality has been carried out.The soil quality of the study area can be classified

into high land, low land and scrub land which either sandy or sandy loam.

Soil samples were collected from six different sampling locations as shown in figure 3.9 in

the season and were analyzed for the soil structure, texture, moisture, content, nutrient

level and other chemical parameters. The present study of the soil profile establishes the

baseline characteristics and this will help in future in identifying the incremental changes if

any, due to the operation of the proposed project. The sampling locations have been

identified with the following objectives:

3.14.3 Interpretation of water quality results

The overall groundwater quality showed moderate to high hardness and was found in the

range of 88-160 mg/l. The data indicate low to moderate mineral content in terms of chlorides,

sulphate. Ground water was found to be free from turbidity. Heavy metals viz. cadmium, chromium,

copper, lead, zinc was estimated in ground water samples. The concentrations of these metals were

found to below the detection limit.

The physico-chemical characteristics of surface water samples are depicted in the Table

3.25. The increase in turbidity is due to shallow depth of the water bodies and high water current.

Turbidity values lay in the range 10 - 18 NTU. Dissolved Oxygen (DO) was observed between 5.8 – 6.5

mg/l ; whereas BOD, chlorides and sulphates were observed in the range of 1.6 – 3.5 mg/l, 18 – 27

mg/l and 1.5 – 3.8 mg/l respectively. From the surface water quality results it can be inferred that all

the parameters analyzed are under the prescribed limit and the water does not contain any

pollutant which would be hazardous for human, animal or crop health.

For confirmation of the data of surface and ground water quality samples from the same

location was collected and analysed during April 2014. The analysis result of surface and ground

water quality has been given in the table below:

Water Analysis conducted during April 2014

3.15 Noise LevelEvaluation of present status of noise level in the core zone & buffer zone was done on hourly

basis for a continuous period of 24 hrs during the season. Another confirmatory noise monitoring

was conducted during April 2014.

For measurement of ambient noise level, a Digital Sound Level Meter was used. The meter

was calibrated with a standard Acoustic Calibrator before using in the field. The measurements were

carried out continuously for the 24-hour period with one hour interval starting at 00.30 hrs to 00.30

hrs next day to obtain hourly equivalent sound pressure level, 1 hour Leq. From these values, day

and night time as well as 24-hour Leq values were also calculated. The Leq is the equivalent

continuous sound level, which is equivalent to the same sound energy as the fluctuating sound

measured in the same period.

The noise levels were monitored on working days only. The stations for monitoring of noise

level have been given in figure 3.11. The results have been presented as minimum, maximum and

average value in table 3.22.

3.16.1 Methodology for Study

The study was aimed at enumeration of the available plant resources and obtaining

a broad representation of the existing floristic variations in the mine lease area and

surrounding mine lease areas. Enumeration of the plant wealth was done by surveying the

area through walking along the gradients of hillocks and valleys followed by collection and

identification of plant specimens. Phyto-sociological aspects of the study were carried out

by perambulating and sampling through quadrates method. Sample plots were selected in

such a way to get maximum representation of different types of vegetation and plots were

laid out in different parts of the areas within the mine area as well as the surrounding mine

area.

From the detailed quantitative field survey the structure and composition of the

community has been expressed quantitatively both in absolute term of each species as well

as in relative term of species with respect to the other species of the study area. While

conducting the study, care was taken to overcome bias due to biotic interference and

proper decision making regarding the method of sampling and number of samples to be

taken. During the survey the pattern of distribution, density and frequency of occurrence of

individual species was recorded.

3.16.5 Economically Important Flora of the study area

a. Agricultural Crops

Paddy was the main crop grown during monsoon season. But with the growing

demand of cotton the paddy cultivation has been shifted to cotton cultivation in most of

the area. Mostly cultivation is rain fed with very less irrigation facility. Apart from the

paddy and cotton, there is the cultivation of sugar cane, Maize, Ground nut, Black gram,

green gram in the area. Vegetable farming is being practiced as backyard cultivation. This

includes cauliflower, lady’s finger, Cucurbits, brinjal, tomato. Vegetable cultivation in large

scale is not been practiced due to lower rain fall and less irrigation facility. Photograph

showing agriculture of the area has been shown in Plate 1.

b. Minor Forest Produces:

Most of the people depend on the forest produces for their livelihood. About 30% of the

livelihood in the locality depend on collection and marketing of Mahua (Madhuca indica)

flower. Apart from the mahua flower other forest produces includes Mahua seed, Sal

leaves, and seeds, Kendu (Diospyros melanoxylon)leaves, Char (Buchnania lanzam) seeds,

fire wood, Kusuma (Schelechera oleosa) seeds, mushrooms during rainy season, Arrow

root, broom sticks.

c. Rare and Endangered Floral Species

Floristic survey of both core and buffer zones of the leasehold area did not

encounter any such species, which can be considered to be critically endangered,

endangered or threatened under the IUCN (International Union for Conservation of Nature

and Natural resources) guidelines.

3.17.1 Demographic profile of the Project AreaThe core zone (ML area) consists of denudated hills with no habitation. With in 1 Km

radius there is one village namely Goendamal with 147 households having a total of 574

inhabitants. In the buffer zone there are 50 villages with 8859 households. The total

population is about 37635 of which 50 % is contributed by males and rest 49 % are females.

Sex ratio indicates that female population is relatively less in the study area. Percentage of

Scheduled Cast population is 15 and that of Scheduled tribe is 21.

3.17.2 Employment & Occupation

As per the base line survey and census data, it has been observed that unlike other parts

of Odisha cultivation is not the major occupation of the villagers in this locality. Only 9.72% of

the working population depends on the cultivation as the main source of income where as

1.86% of the population are mraginal cultivators. This may be because of less land holding,

erractic rainfall and low irrigation facility for the farmers. The people involve in other activities

for their income. The mining and industry in this locality can be able to create good source of

income for the local people. The details occupation pattern is being enumerated in the

Figure 3.14 Occupational Pattern of the Study Area

The occupational profile of the inhabitants shows that only 42.75% of the population is

working and 56.45 % of the population is non-working. Out of the total population 26.4% are

main worker and 17.19% are marginal worker. It can be observed that the main worker section

is dominated by male whereas marginal worker section is dominated by female workers. The

nonworking population is dominated by female. It can be observed from the database as well

as field survey that the area has lack of potential of employment. The other source of income

for the people are dairy, fisheries, goatery, poultry and vegetable cultivation, paddy cultivation ,

cane and bamboo work, and other small business.

3.17.3 Educational ProfileThe literacy rate in the study area is 45.16%, which is less as compare to the other

district of the state. The male literacy rate is 66.06% and the female literacy is 33.93%. Rest

54.88% of the population is illiterate. The Illiteracy is more among the female (62.72%) as

compare to the male. The education infrastructure seems to be good in these villages but lack

of proper teaching staff is a problem. There are 52 Primary Schools, 15 ME Schools and

10 High Schools in these villages. The literacy pattern of the villages in the project area

Literate males are higher in population than literate females. This is probably the reason

for lower employed/working female population than males.

3.17.4 CommunicationThe lease area is well connected with Kantabanjhi in the east and Lathore in the north

with well developed metalled PWD road. The nearest railway station is at Kantabanjhi which is

at a distance of 25 Km from the ML area.

3.17.5 AgricultureThough agriculture is the primary activity of the people in Odisha but in the study area,

major portion of the working population have been diverted from agriculture. The major

reasons for distracting people from agriculture in the area are lack of irrigation facility, smaller

land holding, entire dependence on the rainfall and low fertility of the soil resulting in the poor

agricultural yield. Rice is the main crop grown during monsoon season. Apart from it, vegetable

farming such as tomato, brinjal, bitter gourd, turmeric, cauliflower, gram and ladies-finger is

also an important agricultural practice. Back yard plantation includes Banana, Papaya, Jack

Fruit and Mangoes. Now most of the farmers working as labour in mining industries which are

their prime source of income. About 93.5 % of the agriculture land is rain-fed and the yield of

the crops is dependant on the distribution and quantity of rainfall. Therefore, production of

food grains fluctuates in the years depending on rainfall pattern. Of the total cropped area, rice

commands more than 80%. Kharif crop is dominated by rice. The irrigation facilities available

are given in table 2.29.

four primary health centers and eleven primary health sub-centers in the buffer zone. Buffer

zone also consists of 8 post offices and 20 bus stops. Almost all the villages are supplied with

electricity. Dug wells and hand pumps are the major source of drinking water in the

surrounding villages. The amenities present and drinking water facilities present in the study

area is given in Annexure 6.

4.0 Introduction

In comparison with many other sectors, the potential social and environmental issues

associated with mining and mineral processing operations are both highly significant and

complex to manage. The fixed location of the mineralized zone of interest imposes constraints

on all aspects of mining developments, including the method of mining, location of mine

facilities, requirements for new infrastructure and services (conflict with existing

infrastructure), and the suitability of waste management or disposal methods. This in turn

profoundly influences the environmental, social and health impacts of mining developments, as

well as the economic viability of developing a given mineralized zone.

4.1 Details of Environmental Impacts

The identification of potential environmental impact is first step in the Environmental

Impact Assessment. In order to ensure comprehensiveness the various aspects considered in

impact identification of the project are as follows;

- Investigation of project components

- Investigation of project phases

- Investigation of Impact generating activities

- Investigation of type of Impact

A scientific assessment of the impacts that are likely to influence the existing

environmental scenario is carried out which would facilitate in formulating a suitable

environmental management plan depicting all mitigation measures for sustainable

development of the area. The basic activities involved are:

i) Impact Identificationii) Impact Prediction and Measurement

CHAPTER 4ANTICIPATEDENVIRONMENTALIMPACTS&MITIGATION

MEASURES



83

iii) Impact Interpretation and Evaluationiv) Impact Communicationv) Impact Monitoring and Mitigation

Various techniques are available for impact identification. These include checklists,

matrix, networks cause effect diagrams. In the present study, matrix method has been used.

4.1.1 ChecklistsChecklists methodologies range from listing of environmental factors to highly

structured approaches involving scaling of impacts. Such lists can be modified to reflect the

nature of the developmental activities and the geography of the study area.

4.1.2 MatricesMatrices methodologies identify specific sources of potential environmental impacts,

which provide means for communicating the predicted environmental impacts, and can be

communicable in a graphic form.

4.1.3 Flow Diagrams (Network Method)Flow diagrams are some times used to identify action-effect-impact relationship. The

flow diagram permits the analyst to visualize the connection between action and impact. This

method is best suited to single project assessments, and is not recommended for large regional

actions. The network method has been chosen to list the potential impacts of the proposed

project. The graphical feature of the impact network of mining on different environmental

parameters is being given the figure 4.1 to fig 4.7.

The mining and allied activities as proposed in the project area which influence the

environmental attributes include:

1. Excavation2. Construction of approach and haulage road3. Drilling & blasting4. Loading & transportation of ores and wastes5. Processing & sizing of ores6. Disposal of overburden/waste.7. Stockpiling of low-grade ores.8. Site preparation.

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



84

the proposed mining and allied activities on the various environmental parameters are

discussed.

The pollution potential of a mining project in general is outlined as per Table-4.1 for

general reference.

4.2 Impact of mining on Land environment

4.2.1 Impact on Topography & drainage

The impact on the topography is in the form of changed landscape due to the mining

activities in the form of excavation& dumping of waste. This is confined to core zone only.

Beyond the core zone no such changes in the buffer zone is envisaged.

The main drainage pattern of the area is formed by tributaries of Lant River which flows

at a distance of 1.3 km in the north-east of the ML area. Other small nalas flow in NE to E

directions and join Lant River in the North. There is no seasonal or perennial nala in the lease

area. Direct impact on hydrology is not envisaged.



92

Ground water is likely to occur at a depth of 10 m bgl. The mine is to be worked through

pumping and drain off the quarried area through peripheral drain. The peripheral drain is

provided with a settling tank.

4.2.2 Impact on Land use Pattern

4.2.3 Impact on Land environment and Land use

Mining operations involve development of benches, approach roads, haul roads, drilling,

blasting, excavation and transport and handling of product and waste materials. These activities

can have significant impact on the land environment if proper mitigation measures are not

adopted. Overburden and waste rock including the non-mineralized strata overlying or

interleaving mineralized zones and low grade mineralization which can not be economically

processed is also a source of adverse impact on the land use. The magnitude of such

environmental impacts depends upon

The extent and depth of the mineralized zone

The quantities of material to be mined and disposed of and the effects on dump locations

and designs

The possible inherent toxicity of the wastes

Health and safety issues relating to transportation, storage, use of explosives and toxic

materials.

Management (containment, control, and disposal) of overburden

The potential adverse environmental implications of these activities include impacts on

water quality or hydrology, plant and animal life, loss of natural habitats, resettlement, loss of

cultural heritage or religious sites, effects on visual amenity, noise nuisance, and loss of

agricultural land or forestry resources.

In the present case following are the identified sources which may degrade the land

environment of the area:

o Change in land use due to mining, dumping and infrastructure development.

o Leachates from the waste dump and contaminated water from the mines that may

affecting the characteristic of the top soil affecting the land use.



93

o Mining may affect the ground water regime which may also affect the quality of soil and

land in due course.

Buffer zone will not be affected as the mining operations are confined only to the core

zone. At present 4.982 Ha of land has already degraded due to mining which will increase upto

8.684 Ha during the proposed scheme period and during conceptual period he land degradation

will be 28.802 Ha. Total excavation area will be 17.49 Ha and Overburden will be stored over

3.5 ha of land.

4.2.4 Mitigation Measures:

The reclamation of the degraded land shall be taken up by backfilling the quarries utilizing

the waste material at the site and spreading the top soil over the filled up portion. This will be

followed by plantation activities on the reclaimed are. Check dams and gully plugs will be

constructed to provide an effective arrest of soil erosion.

4.2.5 Solid Waste DisposalThe solid waste generation during the course of mining will be about 10, 50,000 cum. This

solid waste is mainlywall rock. This will be transported to the dump yard located away from the

working area. The top soil generated is stored in soil preservation yard which is located near the

dump yard an over of 0.20 ha.

4.2.6 Toxicity of Waste:

TCLP for three OB samples were carried out for ascertaining its characteristic. The

extraction procedure is called as Toxicity Characteristics leaching procedure (TCLP). The solid

sample was agitated in a rotary agitation device for a specified period. A known quantity of

waste was mixed with 20 times its weight of extraction fluid..The heavy metal concentration in

the leachate is given in table 4.2.

4.2.7 Impact on Air Quality:

The impacts on air environment due to graphite mining and allied activities arise during

land development phase and during mining process. The excavation/removal of topsoil and

Pegmatite, Khandolite and Migmatite host rock, separation of graphite, carriage and dumping

of overburden (top soil and host rock) generates fugitive dust in that area.

The sources of pollution is being given in table 4.3and figure 4.8.

95

4.2.8 Mitigation Measures:

Air pollution control activities includes construction of well compacted roads, regular

water spraying on roads, provision of dust collectors for the drilling machines, controlled

blasting, plantation of wide leaf trees, creepers, tall grasses around quarry sites, roads, colony

and other surrounding barren zones.

Figure 4.8. Sources of Air Pollution

4.2.8.1 Air Quality Modeling:

ISCST3 area source model is used for the prediction of increase in particulate matter

level due to mining activities in the nearby area. The ISC area source algorithm was used to

model ground level release with no plume rise. The ISC OPENPIT source algorithms are used to

model particulate emissions from open pits, such as surface mines. The open pit algorithm uses

an effective area for modeling pit emissions, based on metrological condition. This model uses a

numerical integration approach for modeling impacts from area sources. The model accepts

rectangular areas that may also have a rotation angle specified relative to a North - south

orientation. The rotation angle is specified relative to a vertex used to define the source location

on the card.

The source parameter includes location coordinate of the area. The other parameter which

included in the model input is as follows:



96

Aremis – Area emission rate in g/(s-m2)

Relhgt - Release height above the ground in m.

x init – length of x side of the area in meters.

y init – length of y side of the area

Angle – Orientation angle for rectangular area in degrees from north, measured positive in

clockwise direction

The following source /emission inputs have been considered for air pollution prediction

modeling:

1. Pollution Sources in multiple combinations of active mining areas (as area source) and

haul roads (as line source) have been considered.

2. Emission rates utilized for mines of similar capacity and geo-mining conditions

elsewhere as noted from secondary data have been used for the present case. Emission

rates for active mining area and haul roads have been taken to be 1.4 X 10-7 g/s/m2 and

1.6 x 10-5 g/s/m2 respectively.

3. Extent of quarried area changes with time. Fugitive dust level at any particular time is,

by large extent, function of this available active mining area; haul road length. under a

given set of meteorological conditions.

The impact has been predicted over the study area, which is around 10 km radius of the

project site. It is evident from data furnished in the table 4.4 below that, the PM10

concentration will be maximum within 500 m radial distance and gradually decreases with

increase in distance. Therefore, it can be predicted that, the M.L. area & its vicinity will be

slightly affected by suspended particles; whereas beyond 1km distance no effect will be

envisaged. The isopleths showing the spread of fugitive dust is shown in figure 4.9. The

modeling output has been given in Annexure - 7.

The prediction of air quality due to proposed activities through simulation model shows

that, the maximum incremental Ground Level Concentration (GLC) of PM10 will be 7.8 μ g/m3 in

SW direction at a distance of 500m.

Above result shows that the increase in pollution in the ambient air is low. It has been

predicted from the model output data that the maximum GLC will be at a distance of 300m

from the M.L. area in the prevalent wind directions i.e. SW, S and W directions. It has been

observed during air quality monitoring that, the dust generations are short term and settle

quickly within close ranges.

4.2.9 Impact on Noise Quality:

Different activities in mining such as loading, hauling, drilling, ore handling, mining. lead

to generation of noise. The existing noise level in the core zone as measured at project site of

Goendamal Graphite ore mines is 38 to 45 dB during daytime and 35 to 40 dB during the

nighttime.

The various sources of noise mentioned above shall only be periodical and are 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 generated by different machinery used in mining

operation is given in table 4.5.

Machinery Noise generated in dB (A)

Shovel 90-100Dozer 90-106Dumper 80-100Drill 105Sprinkler 80Backhoe 85

Work zone noise levels in the mining area expected to increase marginally due to

excavation, transportation and host rock handing and separation of graphite from host rock. It

is expected that the generated noise will be contained within the mine lease area and there will

be no profound effect of noise on buffer zone. It is further expected that, the ambient noise

levels within the mine lease area will confirm to National Ambient noise standard prescribed

under Environmental Protection Act, 1986. Noise level at boundary was found to be less than

58 dB. No negative impacts are anticipated at the nearest villages Goendalmal No-7, Bhalpara,

pipalbahal, Kandagadh and villages farther than it.

The noise produced by blasting would be for extremely short duration of around 0.5

seconds, though with a high intensity. The impacts over the surrounding habitat can be

minimized by adopting adequate precautions during blasting and also by properly scheduling of

blasting time. The health hazards of noise exposure is given in table 4.6.

100

4.2.10 Blasting Effects:

Noise of blast is site specific and depends on type, quantity of explosives, dimension of

drill holes, degree of compaction of explosive in the hole and rock. Here the impact of noise will

be very less as the blasting will be performed during the day time. Shot hole drilling &Blasting

will be in practice so that the effect of blasting in terms of fly rock and maximum ground

vibration will be negligible. Time of blasting will be 12 noon to 12.30 PM in day time with prior

intimation to the villagers for taking shelter. The blasting site is located at distance of 450m from

the office. The practice of regularly wetting the blasting ground and spraying water over the

blasted material will be adopted to control air pollution. Proposal is to adopt wet drilling on the

benches.

4.2.11 Impact on Water Quality

The mining activities can cause adverse impacts due to mine drainage, siltation due to

storm water & contaminated water from domestic sewage. Water shall be used only for

Afforestation and domestic purposes which will be met by ground water sources and hence

exploitation of surface water and aquatic biodiversity is not anticipated.

The potential impact on the surface water quality is likely to be due to higher load of

suspended solids. Sources of suspended solids would be:

Discharge of mine runoff during rains to the surface water channels;

Wash off from waste dumps and limestone stock piles during rainy season;

Oil spillage from maintenance of machineries

a. Impact due to Mine drainage Water

The ground water occurs at 316 mRL and mining will continue upto 305 mRL. During the

conceptual period mining activities will intersect the sub surface water regime. About 54 cum/d

of sub surface water will be generated. Two numbers of 15 HP pumps will be used to pump out

the mine water for 6 hours daily for draining of the quarried area through the peripheral drains.

The peripheral drain is provided with settling tank and clean water will be stored and used for

miscellaneous purpose. Excess water will be provided to the farmers for agriculture in the

surrounding areas. The water is neither acidic nor alkaline in nature and it does contain any

harmful chemicals. Hence treatment of water other than desilting is not required.



101

b. Impact due to Water use in Mines:

Water will be mainly used for dust suppression and washing of machineries. Since no

chemical transformation takes place and the ore is naturally occurring there is no possibility of

any chemical contamination in the wastewater. The domestic effluents being generated will be

discharged to soak pits through septic tank.

c. Impact due to Surface Runoff from the Dumps:

The waste dumps are more prone to erosion. The garland drains around the dumpsites

helps to check the flow of fines during the surface runoff and helps in minimizing the impact on

the surrounding environment. Grasses will also be planted on the dump slope to check the soil

erosion.

4.2.12 Impact on Vegetation:

The mining lease area does not include any forest land. The ML area and the buffer

zone is devoid of any endangered flora and fauna species. The existing vegetation with in the

ML area includes few shrubs which are sparsely scattered. As the existing vegetation in the ML

area is very less there will be negligible impact on vegetation of the project area.

4.2.13 Impact on Socioeconomic Conditions

The mine lease area comprises of mainly non-forestland and the project does not

involve any loss of agriculture land. Commencement of mining activity will have beneficial to

the socio-economic environment. It is being proposed to employ 93 persons and provision of

improved infrastructure facility. Preference will be given to skilled, semi skilled and unskilled

categories for employment. General medical facilities of area to be provided to the villagers

from the first – aid – center depending upon the availability. There will be a development of

infrastructural facilities and amenities due to proposed mines in the region.

In terms of the major socio-economic impacts, the project will provide more direct and

indirect job opportunities and better economic standards to the project affected people and

others, through improved infrastructural and community facilities. Development of residential

colony, creation of civic and welfare amenities like primary health care, communications,

educational institutes, recreational facilities, that will develop along with the project will ensure

better quality of life for the local population.



102

4.2.14 Impact on Occupational Health

The process of excavation / quarrying leads to some health hazards. The most significant

occupational health impacts are Noise Induced Hearing Loss (NIHL) and Occupational Lung

Disease (OLD) due to inhalation of dust. As per Mines Rules, 1955, medical examination of

employees at the initial stage and periodically, shall be done by a team of qualified medical

officers provided by the project proponent. Regular medical check up camps shall also be

arranged for detection of occupational diseases and minor disease in the nearby rural

population. Free check up and medicine for treatment for their acute and chronic illness shall

be provided.

4.2.15 Impact on Traffic Density

All transportation will be done by 15T trucks and tippers. Five trucks / tippers are

provided for transportation of ore and waste from mine. The rate of production is 15000 Tonns

per year with 220 no. of working days. Therefore two numbers of trucks will be engaged in

transportation of ore @ 3 trips per day. This truck will be engaged for removal of waste during

the balance period of the week. Hence, there is a very insignificant increase in traffic density of

the locality. This can be manageable within the present capacity of the highway and the

connective link from the highway to project site. The road is wide & black top to sustain the

negligible increase. There shall be an insignificant increase in traffic resulting from to and fro

movement of people.

4.3. Irreversible / Irretrievable Commitments of Environmental Components

Except short term aesthetic change, no irreversible change in the prevailing

environment will be there. The change in landscape is temporary in nature, which will soon be

restored by backfilling of stored overburden and afforestation in that area.

4.4 Significance of Impacts

This activity has two distinct inter-related operations. Firstly it refers to the need to

determine the importance of an impact. Secondly, the relative importance of impacts in

comparison with other impacts of a different nature some times is considered as part of the

impact interpretation. This is termed as evaluation. The environmental impact evaluation

follows the identification and quantification of the impacts. The significant impacts, which have



103

been identified and quantified in the previous chapter, are based on the baseline data

generated in the field during to March to May 2011. The data obtained from other sources like

Indian Meteorological Department, Census of Odisha, Directorate of Economics and Statistics

& other Government Organizations on different aspects have also been utilized. These are

expressed in appropriate units in this chapter so as to get the aggregate score of the

“Environmental Impact” of the mining lease area and its surroundings. This exercise results in a

whole number that could be used in decision making without any ambiguity.

4.4.1 Evaluation of Environmental Impacts

Matrix method has been adopted in this report for the purposes of impact evaluation.

The advantage of matrix method is that it is possible to identify the most severe cause-effect

relationship. The matrix method employs a list of project activities in addition to a checklist of

potentially affected environmental characteristics. These two lists are related in a matrix,

which identify cause-effect relationship between specific activities and impacts.

Among matrix methodologies, “Modified Matrix” has been adopted, similar to matrix method,

involves assignment of “Parameter Importance Value” (PIV) against each environmental

impact parameter. These values are determined by subjective judgment considering the

relative importance or significance of individual parameter. After deciding PIV, these values

have to be distributed among all the cause-effect relationship, which are established between

those particular affected environmental parameters and the concerned project activities by

means of indices, which are called “Relative Parameters Importance Indices” (RPII). The RPII is

chosen in such a way that the sum of all the indices is equal to unity. The value of RPII is

decided based on the relative importance of cause-effect relationships. Higher important one

is given higher RPII value and the next important one is given next higher RPII value.

Another index which is to be determined for each cause effect relationship is called

“Environmental Impact Index” (EII). The scale for EII varies from zero to one. The value one is

assigned to an impact of highest order and zero is assigned to an impact of negligible

magnitude. For adverse impacts, EII carries a negative sign and for beneficial impacts, it carries

positive sign. For determining the value of EII, the environmental impact parameters are

divided into two categories.



104

Category “A” incorporates environmental impact parameters whose quality varies linearly with

the magnitude of impact and includes

- surface and ground water resources

- socio-economic aspects

- land use pattern

- human settlement

Category “B” incorporates environmental impact parameters whose quality varies

logarithmically with the magnitude of impact and includes

- surface ground water quality

- air quality

- noise quality

- health

- Biodiversity

In the later cause, a slight change in impact magnitude will have insignificant change in

environmental quality, but as the magnitude increases, the deterioration in quality increases

logarithmically. The basis for determination of EII for category A and category B are given in

tables 4.7 and 4.8 respectively. After determining EII for each cause-effect relationship the

same will be multiplied with RPII to get a “Weighted Environmental Impact Index” (WEII).

These values are once again multiplied with PIV and addition of all these values gives the

impact score of that particular environmental parameters. The impact score so obtained for all

environmental impact parameters is added together to get total impact score. This total

impact score is used for interpretation and decision-making.

The mining and allied activities, which are likely to cause potential impacts on

environment, are identified and listed as below:

1. Mining operations2. Sizing of ores3. Disposal of solid wastes4. Transportation5. Provision of civic amenities6. Plantation programmeEach of the above activities is discussed below:

1. Mining Operation

This includes the activities like occasional drilling, blasting and excavation.

2. Sizing of Ores

This includes the breaking and sizing of the ore to the required sizes.



106

3. Disposal of solid wastes

The activity includes removal and disposal of solid wastes associated with ore bodies.

4. Transportation

This includes total transportation system i.e. movement of ore from stack yard to the

destination and transportation of overburden waste from mines to dump yard.

5. Provision of civic amenities

Civic amenities like water supply, sewage collection and disposal, recreational facility,

power supply, medical facility and educational facilities will be provided in the residential

colony at the project site.

6. Plantation programme

Development of green belt along the periphery of the lease area, colony area and avenue

plantation along the roadside shall be organized.

The environmental parameters, which are likely to be affected, are given below:

1. Impact on surface water resources2. Impact on ground water resources3. Impact on air quality4. Impact on water quality5. Impact on noise quality6. Impact on health7. Impact on public utilities8. Impact on economic aspects9. Impact on land use and soil characteristics10. Impact on wild life11. Impact on flora12. Impact on human settlement4.4.2 Parameter Importance Value for Environmental Components

The environmental components listed in the earlier section are assigned with PIV so as

to convert the environmental impacts into commensurate units, which could be aggregated

easily to get the total score of environmental impacts. The parameter importance values are

assigned by marking and pair-wise comparison procedure. This procedure involves preparation

of a table containing number of columns corresponding to the range of value, which can be

assigned a “Score of importance” against each impact area. The score of importance is any



107

integer ranging from one to six. The most affected parameters carries a score of six and the

least affected parameter carries a score of one.

4.4.3 Assigning Importance Ranking

The impact areas considered along with their ranking are tabulated. The weightage for

each impact area is calculated by dividing the ranking integer by sum of rankings. The total

parameter importance value is assumed to be 1000 as per the standard practice. The value of

total PIV is distributed among each impact area according to its weightage. The final values

computed by this procedure are also tabulated intable 4.9.

4.4.4 Relative Parameter Importance Index (RPII)

The RPII indicates the importance of interaction between the action and environmental

components. It is assigned any value between 0 and 1 so that the sum of all the values of EPII

under each environmental component is equal to 1. While deciding RPII, first the RPII values

are distributed among adverse and beneficial impacts depending upon their significance. The

RPII values so distributed are once again distributed among the respective interactions



108

depending upon their individual significance. The most importance interaction under a

particular impact area is given the maximum RPII, whereas the least important one is given

minimum RPII. As the significance of impact area increases the RPII also increases.

4.4.5 Environmental Impact Index (EII)

The index represents the magnitude of an impact due to the interaction established

between environmental component and a project activity. The environmental components are

grouped into two categories viz. A and B as discussed in earlier paragraph.

4.4.6 Weighted Environmental Impacts Index (WEII)

The WEII is determined by multiplying RPII and EII of corresponding interaction. The

values are tabulated in table 4.10.

4.4.7 Environmental Impact Matrix without Mitigation Measures

The environment impact matrix incorporating all the environmental components and

project activities (with in-built control measures) is presented in table 4.11. The RPII and EII

values are shown above while the WEII are shown below these against each interaction. The



110

impact score is calculated by multiplying the sum of all WEII’s against each environmental

component by its corresponding PIV. Total impact score is calculated by adding all individual

impact scores. The total impact score is assessed by using following relative scale.

Table 4.11 Impact Score Matrix without Mitigation Measure

Scale

Up to -200 : No appreciable impact on environment

-200 to –400 : Appreciable but reversible impact and measures impact

-400 to –600 : Significant impact mostly reversible after a short period and

that the negative impacts are getting accumulated. Even though, the assimilative capacity of

the region is not damaged completely, it is amply endangered. The mitigation measures for the

present mining and allied activities are important and they are very crucial in the context of

the future development expansions of the existing leases in the region. The predominantly

affected environmental attributes are air quality, water quality, land use, soil characteristics

and health. On the other hand, economic aspects and public utilities in the region will be

benefited with the advent of new industries.

4.5 Mitigation Measures

In order to minimize the impact of the project activities on the ecosystem and to

achieve the desired objectives of mineral excavation the different management strategies are

to be undertaken, which includes both physical as well as socio-economic factors, to minimize

the adverse environmental impacts on the following environmental components.

- Degradation of land/soil

- Degradation of natural vegetation cover/forest

- Water pollution

- Air pollution

- Noise pollution

- Disturbance of habitat

- Disposal and management of waste

- Socio-economic measures

- Occupational safety and health.

4.6 Assessment of Environmental Impacts after Implementation of Mitigation Measures

Assessment of the environmental impacts due to the proposed project after adhering

to different mitigation measures has been computed in the matrix method and presented in

6.1 Risk Assessment and Disaster Management Plan

Risk is the probability of the harm or likelihood of harmful occurrence being released

and its severity. Environmental risk is a measure of the potential threats to the environment,

life and property and which is more likely to happen in the mining activities. All the type of

developmental activities like mining, industries, developmental projects may face certain type

of hazards which can disrupt the normal activities abruptly and lead to disaster like fires,

inundation, failure of machinery, explosion. A risk assessment has been carried out and the

disaster management plan formulated with an aim of taking precautionary measures to control

the hazard propagation and avert disaster and to take such action after the disaster, which

limits the damage to the minimum.

6.2 Objectives

The objectives of environmental risk assessment are governed by the following, which

excludes natural calamities:

a) To identify the potential hazardous areas so that necessary design safety measures can

be adopted to minimize the probability of accidental events.

b) To identify the potential areas of environmental disaster which can be prevented by

proper design of the installations and its controlled operation.

c) To manage the emergency situation or a disastrous event, if any, from the mining

operation.

The major hazards related to the mining activities are as follows:

Open cast bench slope failure

Accident due to fall of quarry sides

Accident due to machineries

Accident due to explosives

Electrical hazards

123

6.3 Environmental Risk Evaluation

From environmental hazards point of view for the mining activities and processing of

ore in various point of work the relative risk potential analysis is made on the following three

factors:

Likelihood of occurrence

Likelihood of detection

Severity of consequence

Each of these factors is graded and compiled to determine the risk potential. The factors

governing the determination of relative risk potentials are presented in the table 6.1.

Table 6.1 Determination of Risk Potential

Very High 5 Very High 1 None 2

High 4 High 2 Minor 4

Moderate 3 Moderate 3 Low 6

Low 2 Low 4 Moderate 8

Very Low 1 Very Low 5 High 10

Risk Potential (Rp) = (A + B) x C

Based on the above stated criteria for assessing the risk, each probable event has been

evaluated by addressing several questions on the probability of event occurrence in view of the

in-built design features detection response, operational practice and its likely consequence.

The major risk associated with the project activities are as follows:

6.3.1 Open Cast Bench Slope Failure

The bench slopes are to be monitored regularly by sensitive instruments at precise level

at regular intervals to check for any possible ground movement. A well-developed drainage

system over the leasehold area is to ensured & check the water flows out of the lease area.

- Development of socio economic status of the people of the project area

- Decrease in the rate of migration from the project villages as the employment

opportunity will be created in the locality.



132

The potential impacts the project have been discussed in Chapter 4. It is evident that the

proposed activities will have negligible adverse impact on different environmental

components. To mitigate such adverse impacts, appropriate remedial measurers have been

proposed. An EMP is an implementation plan to mitigate and offset the adverse environmental

impacts of the project and to protect and where possible, enhance the environment. EMP

should be viewed as a legal commitment on the part of the proponent to minimize

environmental impacts. This chapter proposes Environmental Management Plan (EMP), which

will be an integral part of the project for minimizing the adverse impacts and to ensure the

sustainable development of the area.

8.1 Objectives

The EMP has been worked out with the following objectives:

Reclamation of the mined out area where ever and when ever possible.

Restoration of landscape as near to its original form as far as possible, consistent with

the economy of mining operations, keeping in view the drainage pattern, geological

stability, vegetation.

Minimization, mitigation and where possible elimination of degradation in land, quality

of air and water.

Making least disturbance to the water regime and water quality.

Least disruption to the existing basic ecological status in the mining area during mining.

Improvement of the overall flora scenario of the area.

CHAPTER 8

ENVIRONMENTAL MANAGEMENT PLAN



133

8.2 Planning to Maintain Better Environment in the Area

The following broad categories of environmental factors have been taken into

consideration in order to prepare sustainable environmental management plan. These impacts

include:

- Degradation of land/soil

- Disposal & management of Solid waste

- Degradation of natural vegetation cover/forest

- Water pollution

- Air pollution

- Noise pollution

- Forest & Vegetation cover

- Socio-economic measures

- Occupational safety and health.

8.3 Reclamation of Degraded Land/ Land Soil Management

Quarry 2 and 3 over an area of 0.633 Ha will be backfilled with 73678 m3 of wasteafter

complete exhaustion of quarry.Top soil cover will be spread over the backfilled area to make it

stable and fertile. Plantations will be developed over the backfilled area to attain the pre mining

land use. Cow dung manure will be applied at the rate of 2500 kg/Ha to improve soil fertility.

Utmost care will be undertaken to ensure the survival & growth of the existing plantation and

drought resistant and fast growing trees will be planted.Quarry 1 & 4 over an area of 11.854 Ha

will be used as water reservoir for rain water harvesting after the exhaution. During conceptual

period 5.003 Ha of mined out area will be backfilled and plantation will be done over the

backfilled area.The details of reclamation, rehabilitation and backfilling plan has been given in

table 8.1 and 8.2.

The details of land use, reclamation of degraded land and afforestation details has been given

in Annexure 9 (Table 1,2& 3).

8.3.1 Solid Waste Management:a. Top soil management

Top soil in the proposed mining area is fertile in nature. During plan period 2830cum

and during the conceptual period 74850cum of top soil will be generated. Generated top soil

will be stored over an area of 0.20 Ha. The top soil will be spread over the backfilled area and

plantation will be done over that.

b. Waste disposal & management:The waste generated during plan period and conceptual period will be 163400 cum and 10,

50,000 cum respectively. During the conceptual period 3.5 Ha of land will be covered under

dump. Waste will be completely used for backfilling of mined out quarries. Therefore no waste

dump will be left over after the conceptual period. Retaining wall will be provided around the

dump to arrest the silt & loose materials. Garland drain with settling tank to be provided at a

distance of 3m from the retaining wall to settle down the heavy particles. The detail size of

garland drains & settling tank has been given in table 8.3.

Proposed Dump 500m x 1.5 x 2 m 500 x 1.5 m

c. Dump Management Practices:

It has been envisaged that appropriate dump management practice will be undertaken

to create waste dump for disposal of the mineral rejects. In order to protect the dumps from

erosion the following measures can be recommended:

The dump will be adequately benched. The ultimate slope will be maintained at 20o –

22o with individual terrace slope not exceeding 37o.

The individual terrace height will be maintained at 8m.

Each terrace will have inward slope with catch drains at inward side of the terrace and

the catch drain of the individual terrace will be connected to the garland drain outside

the periphery of the dump.

The catch drains will have half concrete open pipes followed by settling tanks to avoid

wash offs.

The dump bench slope will be vegetated with grasses to avoid erosion by wind & water

and in latter stage, the dump will be utilized for backfilling of the exhausted quarry.

Retaining wall and garland drains for the proposed waste dump will be constructed to

arrest wash offs from the dump.

The afforestation programe will be carried out from the 1st year of the scheme period. The

details of environmental management plan showing different activities has been given in Figure

8.1.



136

Figure 8.1. Environment Management Plan



137

8.4 Water Management & Water Pollution Control

8.41 Surface Water Management

No perennial water body is present in the close proximity to the mine. Surface runoff

around the quarries and dumps near the natural drains will follow the garland drains to arrest

the eroded sediments, which shall pass through a series of garland drains before being

discharged to the natural drainage system. This practice shall be carried out only in rainy season

at the time of heavy rains. Other wise the water from garland drains shall be collected in

reservoirs after settling and shall be used for afforestation uses. The sediments thus collected

shall be analyzed for hazardous substances. Quarterly monitoring of water quality will be done

and for this purpose water quality monitoring station will be erected.

The pumped out water from the mining pit will be guided through channel and this

water will not cause any adverse impact on the water regime of the area. A boulder bund will

be provided beyond the toe of the waste dump which retains dump wash offs during rains. At a

distance of 3-4m beyond the retaining wall, a garland drain with settling tank (5mx15mx5m) is

provided to allow slime and silt to settle down. There after only clean water is allowed to pass

to the adjacent area.

8.4.2 Ground Water Management

The ground water table of the area is 10 m below ground level. So seepage of water is

likely to be encountered when the mining activities continue below this depth. The ground

water occurs at 316 mRL and mining will continue upto 305 mRL. During the conceptual period

mining activities will intersect the sub surface water regime. About 54 cum/d of sub surface

water will be generated. Two numbers of 15 HP pumps will be used to pump out the mine

water for 6 hours daily for draining of the quarried area through the peripheral drains. The

peripheral drain is provided with settling tank and clean water will be stored and used for

miscellaneous purpose. Excess water will be provided to the farmers for agriculture in the

surrounding areas. The water is neither acidic nor alkaline in nature and it does contain any

harmful chemicals. Hence treatment of water other than desilting is not required.The project

got clearance from central ground water board for water requirement of 64 cu.m/ day includes

54 cum/day of mine seepage water.



138

8.4.3 Rain Water Harvesting

In the first phase Quarry no. 1 & 4 will be dedicated for rainwater storage reservoir.

Following considerations are made for RWH;

The total quarry area = 4095 Sq.m.

Total roof top area of the office building = 1000 Sq.m

Annual avg. rainfalls: 1384mm (Historical data of 10yrs)

Hourly rainfall of peak intensity: 50 mm

15 minutes rainfall of peak intensity: 22 mm

Rate of rainfall: 0.022 m/hr

Runoff Coefficient for roof top (corrugated): 0.70

Coefficient of evaporation, spillage and first flush wastage: 0.80

8.4.3.1 Harvestable rain water from the ML area

Corrugated roof top (1000 sq m)

1000 x 1.384 = 1384 cum

Possible harvestable quantity: 1384 x 0.70 x 0.80 = 775 cum

Quarry Areas (4095 sq m)

4095 x 1.384= 5667 cum

Possible harvestable quantity: 5667 x 0.80 = 4533 cum

8.4.3.2 Storage facilities

Through rain barrels of capacity 3 x 1000 lts

Assuming daily use of 3 cum per day

8.5 Air Pollution ControlIn order to reduce fugitive dust emissions during loading/unloading of overburden and

topsoil, water will be sprayed. Topsoil banks and overburden dumps will be periodically wetted

to reduce fugitive dust generation.

Haul roads are expected to be the major source of fugitive dust. To reduce dust from

haul roads the following measures will be taken:



139

The unmetalled hauls roads shall be adequately compacted before being put into use.

Periodically water will be sprinkled on these roads in amounts just sufficient to wet the

surface. Water will also be sprinkled on stacks of topsoil.

Overloading of transport equipment shall be prevented in order to stop spillage.

Wherever possible by the sides of haul roads, trees will be planted.

Following control measures are suggested for controlling the emission of particulate

matter to permissible limit.

Stock piles Mist spraysHaul roads Trucks to be covered with tarpaulin and over filling of tippers

to be strictly avoided maintenance of haulage road onregular basis.Regular water spraying on haulage roads(Twice daily)

8.6 Noise Pollution Control

Noise level shall be maintained below 70 dB (A) in the working zone (for 8 hr. Exposure).

The mitigation measures for noise are of following types:

Prevention at source

Attenuation in transmission path and

Protective measures on work environment.

The following measures will be taken up to reduce the noise level:

Diesel powered machineries, which are major; source of noise in open cast environment

will be properly maintained. Scheduled to prevent undesirable noise. Attention shall be

paid towards rigorous maintenance of the silencer of the diesel engines.

Static diesel engines shall be housed as far as possible. If possible they will be placed on

vibration isolators.



140

Truck drivers will be issued ear plugs and ear muffs. Duty of the operators of the noisy

machineries will be regulated to keep their noise exposures levels with in the limits

Green belt will be developed around the office building and mine to reduce noise

exposure level.

8.7 Protective measures for ground vibration/ Air blast caused by Blasting8.7.1 Control Measures for Vibration

Blast design can be altered to result in reduced levels of ground vibration by:

Reducing the maximum instantaneous charge (MIC) by using delays, reduced hole

diameter and/or deck loading.

Blast vibration research shows the level of ground vibration is proportional to the Scaled

Distance (vibration) which is defined as the distance to the blast divided by the square

root of the MIC. So, at a given distance, reducing the MIC will generally result in lower

levels of vibration.

Changing the burden and spacing by: altering the drilling pattern, and/or delay layout,

or altering the hole inclination.

Exercise strict control over spacing and orienting all blast drill holes.

Establish times of blasting to suit local conditions.

8.7.2 Control Measures for Noise Selecting low noise plant and equipment incorporating available noise control kits.

Optimum placement of waste dumps, location of haul roads, location of fixed plant

loading hoppers. Waste dumps, stockpiles can be used to shield fixed items of plant

which generate noise.

Provision of sound walls and acoustical screening.

Also, earth embankments can often be constructed from overburden, from stripping

and initial excavation works and provide an alternative means of stockpiling soil for

future rehabilitation works.

Incorporating optimum buffer zones and setback distances. This is only of use where

large distances are involved. In general, doubling the distance between the source and

receiver will result in a 6 dBA reduction in noise level.

8.8 Green Belt Development

Plantation of different tree species plays an important role in restoring the productivity,

eco-system stability and biological diversity to the degraded lands and helps to decrease the air

pollution. Therefore, an effective plantation programme has been planned to stabilize the eco-

system and decrease the pollution load. At present, it is proposed to have at least 7.5 meters

wide green belt all around the ML area by planting suitable species of evergreen and broad

leaves type. Plantation is also envisaged on both sides of the mine road, waste dump and top

soil dump. Where tree plantations will not be feasible, the unpaved land shall be covered with

grass and small height bushes in order to avoid soil erosion.

Plantation within the ML area has been initiated since 2003. There are existing

plantation over an area of 1.0 Ha with 1522 no. of saplings. Photograph showing plantation in

mining area has been shown in Plate 3.

The details of the existing plantation within the ML area has been given in the table 8.5

8.11 EMP Implementation and Monitoring

A large part of the sampling and measurement activities will be concerned with long

term monitoring aimed at providing an early warning of any undesirable changes or trends in

the natural environment that could be associated with mining and allied activities. This is

essential to determine where the changes are a response to a cycle of climatic conditions or are

due to the mining and allied activities.

In particular, a monitoring strategy is required to ensure that all environmental resources,

which may be subjected to contamination, are kept under review. Monitoring of the individual

elements of the environment is necessary.

To meet the above objective an “Environmental Management and Monitoring Department

(EMMD)” will be formed which will be responsible for implementation of EMP and post

operation monitoring. The officers of the department will meet frequently to assess the

progress and analyze the data collected during the preceding fortnight/month.

8.684 Ha during the proposed scheme period and during conceptual period he land degradation

will be 28.802 Ha.Preset dumping area is 1.51 Ha which extends upto 3.5 Ha during the conceptual

period. Presently 4.97 Ha of land has been degraded due to mining activities which will increase to

26.7 Ha during the conceptual period

9.3 Baseline Environmental Status

The EIA/EMP report is based on the data generated from March 2011 to May 2011.The

study area is confined to 10 km radius of the ML area. The baseline data was revalidated with

the fresh data collected during April 2014 by M/s Cleenviron Pvt. Ltd., Odisha (NABL accredited

laboratory).



155

9.3.1Land Use Pattern

Land pattern use as shown in the satellite imagery around 10 km radius shows that the

project area constitutes mainly crop land and forests. Crop land occupies 43.00 % and forest

land occupies 37.00 % of the total land area respectively. Waste land covers an area of 14.6 %.

Land degraded due to mining activities is about 0.3 %.

9.3.2 Soil Type in the Study Area:

The soil quality of the study area can be classified into high land, low land and scrub land

which either sandy or sandy loam.

9.3.3 Climate and Meteorological Parameters

The rainfall in the area is mostly because of south – west monsoon. The annual average rainfall

of about 1384 mm occurs during the monsoon period and the average number of rainy days is

around 70. The climate is characterized by high inter-annual variability. Temperatures vary

according to altitude and are highest in May (up to 47°C) and lowest in January (down to 12°C).

9.3.4 Ambient Air Quality

Ambient air quality monitoring was carried out at eight locations within 10 Kms radius

including AAQMS in downwind direction. The concentration of PM10 was found to be in the

range of 27 – 48 µg/m3, SO2 in the range of 4.3 – 5.7 µg/m3 and NOx in the range of 9.7-13.5

µg/m3.

9.3.5 Soil Quality

It has been observed that the pH of the soil in the study area ranged from 7.0 to 7.8. The

electrical conductivity was observed to be in the range of 283 - 422 µmhos/cm. The electric

conductivity is favorable for the agricultural activities. The nitrogen values range between 224 –

356 kg/ha. The phosphorus values ranged between 17 to 41 kg/ha indicating poor to medium

fertility of the soil with respect to P content. The potassium value ranged between 132 – 254

kg/ha. The textural class of the samples analyzed is found to be sandy silt. The bulk density of

the soil is found to be 0.98 to 1.32 gm/cc. The percentage of organic matter content reveals

poor to medium fertile soils in the region.



156

9.3.6 Water Quality

The overall groundwater quality showed moderate to high hardness and was found

in the range of 88-160 mg/l. The data indicate low to moderate mineral content in terms of

chlorides, sulphate. Ground water was found to be free from turbidity. Heavy metals viz.

cadmium, chromium, copper, lead, zinc was not found in ground water samples.

The surface water analysis result shows turbidity values lie in the range 10 - 18 NTU.

Dissolved Oxygen (DO) was observed between 5.8 – 6.5 mg/l ; whereas BOD, chlorides and

sulphates were observed in the range of 1.6 – 3.5, 18 - 27 and 1.5 – 3.8 mg/l respectively. From

the surface water quality results it can be inferred that all the parameters analyzed are under

the prescribed limit and the water does not contain any pollutant which would be hazardous

for human, animal or crop health.

9.3.7 Noise Level

157

9.3.12 Socioeconomic Profile of the Study Area

The core zone (ML area) consists of denudated hills with no habitation. With in 1 Km

radius there is one village namely Goendamal with 147 households having a total of 574



9.3.13 Educational Profile

The literacy rate in the study area is 45.16%, which is less as compare to the other

district of the state. The male literacy rate is 66.06% and the female literacy is 33.93%. Rest

54.88% of the population are illiterate. The Illiteracy is more among the female (62.72%) as

compare to the male. The education infrastructure seems to be good in these villages but lack

of proper teaching staff is a problem. There are 52 Primary Schools, 15 ME Schools and 10 High

Schools in these villages.

9.4 Anticipated Environmental Impacts and Mitigation Measures

9.4.1 Impact on Topography & drainage

The main drainage pattern of the area is formed by tributaries of Lant River which flows

at a distance of 1.3 km in the north-east of the ML area. Other small nalas flow in NE to E


area. Direct impact on hydrology is not envisaged.

Ground water is likely to occur at a depth of 10 m bgl. The mine is to be worked through

pumping and drain off the quarried area through peripheral drain. The peripheral drain is

provided with a settling tank.

9.4.2 Impact on Land use Pattern

Buffer zone will not be affected as the mining operations are confined only to the core

zone. During the life of the mine, 17.49 hectares will be utilised for mining, activities. At present

4.982 Ha of land has already degraded due to mining which will increase upto 8.684 Ha during the

proposed scheme period and during conceptual period he land degradation will be 28.802 Ha.

Total excavation area will be 17.49 Ha and Overburden will be stored over 3.5 ha of land.



158

9.4.3 Impact on Air Quality

The impacts on air environment due to Graphite mining and allied activities arises

during land development phase and during mining process. The excavation/removal of topsoil

and Pegmatite, Khandolite and Migmatite host rock, separation of graphite, carriage and

dumping of overburden (top soil and host rock) generates fugitive dust in that area. Dust

suppression through spraying of water is to be adopted to minimize its harmful effect.

9.4.4 Air Quality Modeling

ISCST3 area source model is used for the prediction of increase in fugitive dust level due

to mining activities in the nearby area. It has been predicted that the PM10 concentration will

be maximum within 500 m radial distance and gradually decreases with increase in distance.

The prediction of air quality due to proposed activities through simulation model shows that,

the maximum incremental Ground Level Concentration (GLC) of PM10 will be 7.8 μ g/m3 in SW

direction at a distance of 500m.

9.4.5 Impact on Noise Quality

Different activities in mining such as loading, hauling, drilling, ore handling, mining. lead

to generation of noise. The existing noise level in the core zone as measured at project site of

Goendamal Graphite ore mines is 38 to 45 dB during daytime and 35 to 40 dB during the

nighttime.

9.4.6 Blasting Effects

Shot hole drilling &blasting will be in practice so that the effect of blasting in terms of fly

rock and maximum ground vibration will be negligible. Time of blasting will be 12 noon to 12.30

PM in day time with prior intimation to the villagers for taking shelter. The practice of regularly

wetting the blasting ground and spraying water over the blasted material will be adopted to

control air pollution. Proposal is to adopt wet drilling on the benches.

9.4.7 Impact on Water Quality

The ground water occurs at 316 mRL and mining will continue upto 305 mRL. During the

conceptual period mining activities will intersect the sub surface water regime. About 54 cum/d

of sub surface water will be generated. Two numbers of 15 HP pumps will be used to pump out

the mine water for 6 hours daily for draining of the quarried area through the peripheral drains.



159

9.4.8 Impact on Vegetation

The mining lease area does not include any forest land. The ML area and the buffer

zone is devoid of any endangered flora and fauna species. The existing vegetation with in the

ML area includes few shrubs which are sparsely scattered.

9.4.9 Impact on Socioeconomic Conditions

The mine lease area comprises of mainly non-forestland and the project does not

involve any loss of agriculture land. Commencement of mining activity will have beneficial to

the socio-economic environment. It is being proposed to employ 93 persons and provision of

improved infrastructure facility. Preference will be given to local skilled, semi skilled and

unskilled categories for employment. General medical facilities of area to be provided to the

villagers from the first – aid – center depending upon the availability. There will be a

development of infrastructural facilities and amenities due to proposed mines in the region.

9.5 Environmental Management Plan

9.5.1 Reclamation of Degraded Land/ land Soil Management

Quarry 2 and 3 will be backfilled after complete exhaustion of the quarries with 73678 m3

of waste.Top soil cover will be spread over the backfilled area to make it stable and fertile.

Plantations will be developed over the backfilled area to attain the pre mining land use. Cow dung

manure will be applied at the rate of 2500 kg/Ha to improve soil fertility. Utmost care will be

undertaken to ensure the survival & growth of the existing plantation and drought resistant and

fast growing trees will be planted.Quarry 1 & 4 will be used as water reservoir for rain water

harvesting. During conceptual period 5.003 Ha of mined out area will be backfilled and planted

over.

9.5.2 Solid Waste Management

9.5.2.1 Top soil management

Top soil in the proposed mining area is fertile in nature. During the planning period 2830

m3of top soil will be generated. The top soil will be spread over the backfilled area and

plantation will be done over that.



160

9.5.2.2 Waste disposal & management:

The waste generated during plan period and conceptual period will be 163400 cum and

10, 50,000 cum respectively. During the conceptual period 3.5 Ha of land will be covered under

dump. Waste will be completely used for backfilling of mined out quarries. Therefore no waste

dump will be left over after the conceptual period.

9.5.3 Water Management & Water Pollution Control:

No perennial water body is present in the close proximity to the mine. Surface runoff

around the quarries and dumps near the natural drains will follow the garland drains to arrest

the eroded sediments.

9.5.4 Rain Water HarvestingIn the first phase Quarry no. 1 & 4 will be dedicated for rainwater storage reservoir.

About 775 cum/annum of rain water will be harvested which will be stored in rain barrels of

capacity 3 x 1000 lts.

9.5.5 Air Pollution ControlFollowing control measures are suggested for controlling the emission of particulate

matter to permissible limit.

Table 8.2. Suggested Air pollution Control Measures

Areas of dust generation Suggested pollution control measures

Faces/sites before and after

blasting Faces/sites while loading


Drill machines Dust extraction systems

Use of sharp drill bits for drilling holes and drills with

water flushing systems (wet drilling) to reduce dust

generation.

Stock piles Mist sprays

Haul roads Trucks to be covered with tarpaulin and over filling of

tippers to be strictly avoided maintenance of haulage

road on regular basis.

Regular water spraying on haulage roads

9.5.6 Noise Pollution Control



161

Noise level shall be maintained below 70 dB (A) in the working zone (for 8 hr. Exposure).

Diesel powered machineries, which are major; source of noise in open cast environment will be

properly maintained. Attention shall be paid towards rigorous maintenance of the silencer of

the diesel engines.Static diesel engines shall be housed as far as possible. If possible they will be

placed on vibration isolators.

9.5.7 Protective Measures for Ground Vibration/ Air Blast Caused By Blasting:Blast design can be altered to result in reduced levels of ground vibration by:

Reducing the maximum instantaneous charge (MIC) by using delays, reduced hole

diameter and/or deck loading.

Changing the burden and spacing by: altering the drilling pattern, and/or delay layout,

or altering the hole inclination.

Exercise strict control over spacing and orienting all blast drill holes.

Establish times of blasting to suit local conditions.

9.5.8 Green Belt DevelopmentPlantation within the ML area has been initiated since 2003. There is existing plantation

over an area of 1.0 Ha with 1522 no. of saplings. The year wise plantation programme is also

proposed in the EIA report.

2 Water pollution Surface runoff around the quarries anddumps near the natural drains will follow the

√



26

garland drains to arrest the eroded sediments,and pass through a series of garland drainsbefore discharged to the natural drainagesystem.

The water from garland drains shall becollected in reservoirs after settling and shallbe used for afforestation uses.

A boulder bund will be provided beyond thetoe of the waste dump which retains dumpwash offs during rains. At a distance of 3-4mbeyond the retaining wall, a garland drainwith settling tank (5mx15mx5m) is providedto allow slime and silt to settle down. Thereafter only clean water is allowed to pass tothe adjacent area.

Excess water will be provided to the farmersfor agriculture in the surrounding areas.

3. Water conservation Rain water conservation method will followedto recharge the ground water table.

4. Noise pollution Diesel powered machineries, which are major;source of noise in open cast environment willbe properly maintained. Scheduled to preventundesirable noise. Attention shall be paidtowards rigorous maintenance of the silencerof the diesel engines.

Static diesel engines shall be housed as far aspossible. If possible they will be placed onvibration isolators.

Truck drivers will be issued ear plugs and earmuffs. Duty of the operators of the noisymachineries will be regulated to keep theirnoise exposures levels within the limits

Green belt will be developed around the officebuilding and mine to reduce noise exposurelevel.

5. Solid waste /Tailings

Waste generated during the mining operationwill be stored in the demarcated dumping sites.The dump management measures includes asfollows: The dump will be adequately benched. The

ultimate slope will be maintained at 20o – 22o

with individual terrace slope not exceeding



27

37o. The individual terrace height will be

maintained at 8m. Each terrace will have inward slope with

catch drains at inward side of the terrace andthe catch drain of the individual terrace willbe connected to the garland drain outside theperiphery of the dump.

The catch drains will have half concrete openpipes followed by settling tanks to avoid washoffs.

The dump bench slope will be vegetated withgrasses to avoid erosion by wind & water andin latter stage, the dump will be utilized forbackfilling of the exhausted quarry.

Retaining wall and garland drains for theproposed waste dump will be constructed toarrest wash offs from the dump.

6. Land degradation The degraded land due to the mining activitywill be backfilled by the waste generated fromthe mines and reclaimed by plantation

7. Erosion &Sediment8. Top soil The top soil generated will be spread over the

backfilled area and plantation was done on thearea.

9. Ground vibration Reducing the maximum instantaneous charge(MIC) by using delays, reduced holediameter and/or deck loading.

Blast vibration research shows the level ofground vibration is proportional to the ScaledDistance (vibration) which is defined as thedistance to the blast divided by the squareroot of the MIC. So, at a given distance,reducing the MIC will generally result inlower levels of vibration.

Changing the burden and spacing by: alteringthe drilling pattern, and/or delay layout, oraltering the hole inclination.

Exercise strict control over spacing andorienting all blast drill holes.

Establish times of blasting to suit localconditions.

10. Wildlifeconservation

There is no wildlife corridors or sanctuarylocated in the buffer zone of the area. Howeverfor conservation of wild life and prevent thedamage to the wildlife due to mining activitythe following measures will be undertaken:

mining quarry will be fenced properly The fencing around the lease area prevent the

wildlife to come inside the lease area. The blasting operation will be done in the

day time only. Transportation of the ore will be done

preferably in the day time.11. Forest protection There are 8 reserved forests present within the

buffer zone of the project area. The proponentwill take necessary steps for protection of theforest.

Annexure-11HYDROGEOLOGICAL REPORTFOR GOENDAMAL GRAPHITE ORE MINES

CHAPTER 1INTRODUCTION

1.0 INTRODUCTION

Goendamal Graphite Mine is located in Goendamal village in Turekela block in Bolangir

district of Odisha State. The mining lease area spreads over an area of 63.771 hectares

(157.58 acres). The lease was executed in favour of Shri Natwarlal Agarwal on 11.05.1998 for

a period of 30 years which is valid upto 10.05.2028. Mining plan was approved under Rule of

22 of Mineral Conservation and Development Rules 1960 vide letter No. CAL/BG/Gr/MP/540

dated 18.03.1998. Shri. N.L.Agarwal started mining operation with effect from middle of

1998. Mining activity has been discontinued since October 2009 due to requirement of

Environmental clearance. The present mining scheme was prepared for the period of 2013-14

to 2017-18 and approved by Indian Bureau of Mines, vide letter no. MS/OTFM/55-

ORI/BHU/2012-13 dated 13.08.2013.

1.2 MINING LEASE AREA

Goendamal Graphite Ore Mining Lease area spreads over an area of 63.771 hectares of non-

forest land. The lease area is flat and undulating topography with surface elevation varies in

the range between 326 (in the north-east) and 348m.amsl in the south.(Surface Mining Plan

in plate no.1). There are 5 (five) nos. of quarries i.e. quarry no.1, 2, 3, 4, & 5 but mining will be

resumed only in quarry no.5 (Approved IBM Mining Plan in Plate no.2). Since mining has

intersected local water table, de-watering of mining pit is required for safe mining operation.

De-watering of mining seepage has been described in chapter- 9.

1.3 MINING METHODS

The method of mining is “A” OTFM Method. Benches are making with a maximum height of

3m and minimum width of 3m sloping nearly vertical with overall quarry slope at 370. The

year wise development of the quarry is shown by plan and sections in plate no. III. Existing

Quarry ( no.5) will be developed further to depth and towards south for raising ore in the

ensuring scheme period. Labours will be deployed on the face for excavation and loading

purpose. Equipments like crowbar, pickaxe, spade, chisel, hand shovel. will be used. Where

ever necessary small capacity poclainer (09 CuM) will be used for loading and transportation

purpose 15 tonne tippers will be used. Total annual production will be 15000 tonnes.

Average working days during the year will be 220 days. Average daily production is about

68.18 tonnes.

1.3.1 Dimension of Quarry

Based upon the surface geological data, the excavation planning is confined to the existing

quarry namely Quarry-5. The average annual output has been proposed to be 15000 MT of

graphite ore. The mineral will be exploited by Semi-mechanized means. The Year-wise

volume of excavation, ore recovery, generation of waste, RL of benches and stripping ration

for each year has been mentioned in the following table.

Agriculture is the main occupation of the people. Paddy is the principal crops grown in the

area. Cotton now a days has become a commercial crop in the area. Total agricultural lands

accounts about 43 % of the study area. Some families depend upon the forest product and

few are engaged in the mining sector primarily graphite mining in the area. The forest land

coverage of the buffer zone is about 38.8% of the total area and waste land is about 14.6% .

2.2.1 Demographic profile of the Project Area

The core zone (ML area) consists of denudated hills with no habitation. With in 1 Km radius

there is one village namely Goendamal with 147 households having a total of 574



Sex ratio indicates that female population is relatively less in the study area. Percentage of

Scheduled Cast population is 15 and that of Scheduled tribe is 21.

2.2.2 Employment & Occupation

As per the base line survey and census data, it has been observed that unlike other parts of

Odisha cultivation is not the major occupation of the villagers in this locality. Only 9.72% of

the working population depends on the cultivation as the main source of income where as

1.86% of the population are mraginal cultivators. This may be because of less land holding,

erractic rainfall and low irrigation facility for the farmers. The people involve in other

activities like daily wage, animal husbandry, NTFP collecation and marketing, mining and

indurial labour for their income. The mining and industry in this locality can be able to create

good source of income for the local people. The details occupation pattern is being

enumerated in the following table 2.5.

main worker and 17.19% are marginal worker. It can be observed that the main worker

section is dominated by male whereas marginal worker section is dominated by female

workers. The nonworking population is dominated by female. It can be observed from the

database as well as field survey that the area has lack of potential of employment. The other

source of income for the people are dairy, fisheries, goatery, poultry and vegetable

cultivation, paddy cultivation , cane and bamboo work, and other small business.



59

2.2.3 Agriculture

Though agriculture is the primary activity of the people in Odisha but in the study area, major

portion of the working population have been diverted from agriculture. The major reasons for

distracting people from agriculture in the area are lack of irrigation facility, smaller land

holding, entire dependence on the rainfall and low fertility of the soil resulting in the poor

agricultural yield. Rice is the main crop grown during monsoon season. Apart from it,

vegetable farming such as tomato, brinjal, bitter gourd, turmeric, cauliflower, gram and

ladies-finger is also an important agricultural practice. Back yard plantation includes Banana,

Papaya, Jack Fruit and Mangoes. Now most of the farmers working as labours in mining

industries which are their prime source of income. About 93.5 % of the agriculture land is

rain-fed and the yield of the crops is dependant on the distribution and quantity of rainfall.

Therefore, production of food grains fluctuates in the years depending on rainfall pattern. Of

the total cropped area, rice commands more than 80%. Kharif crop is dominated by rice. The

irrigation facilities available are given in table 2.6.

The project village consists of one high school one senior secondary school also. There are

four primary health centers and eleven primary health sub-centers in the buffer zone. Buffer

zone also consists of 8 post offices and 20 bus stops. Almost all the villages are supplied with

electricity. Dug wells and hand pumps are the major source of drinking water in the

surrounding villages.

CHAPTER 3CLIMATE

The study area experiences a tropical climate with a hot and dry summer and pleasant winter

intervened by south-west monsoon season. The summer season extends from March to

middle of June followed by rainy season from mid-June to mid-October. The winter season

extends from November till the end of February.

3.1 TEMPERATURE

The temperature in the study area starts rising from March to May, which is the hottest

month of the year with mean daily maximum temperature 43oC. However in 2005 June was

the hottest month with a maximum temperature of 48oC. With the advent of monsoon,

temperature starts reducing and the winter season starts from November. December is the

coldest month of the year with mean daily maximum temperature of about 27oC and the

temperature coming down to a minimum of about 6oC.

3.2 HUMIDITY AND WIND

Humidity of the air is generally high during south-west monsoon period and low during winter

months. The relative humidity varies from 26% to 84% throughout the year. The mean

monthly potential evapo-transpiration value ranges from 4mm in December to 470mm in

May.

Wind is generally light to moderate. Wind velocity increases during summer and south-west

monsoon months. The mean annual wind speed is 3.3km/hr.

3.3 RAINFALL

The south-west monsoon is the principal source of precipitation in the study area. The

average annual rainfall of the study area is 1193 mm (2004-2012). About 80% of the total

rainfall is received during the period from June to September. Droughts are quite common in

the study area. The average number of rainy days in a year with rainfall of 2.5mm or more is

about 67.

CHAPTER 4HYDRO-GEOMORPHOLOGY

4.0 GEO MORPHOLOGICAL FEATURESGeomorphic features of an area control the occurrence and movement of ground water.Satellite remote sensing is being widely used for assessment of natural resources due to itssynoptic coverage. A hydro-geomorphological map of 10km radius buffer zone of the projectsite has been prepared through interpretation of remote sensing data along with field groundchecking. The map shows presence of the following hydro-geomorphic units.Structural HillThese are linear to arcuate hills showing definite trend lines. These are associated withfolding, faulting. Around 25% of the study area is covered with structural hills mostly in south-western part of the area in patches in the east and north. The average elevation of the hillranges varies in between 300 and 750 mamsl. The hills are comprises of granite gneisses andkhondalite of the Eastern Ghat Super Group of. High surface elevation with moderate to steepslope and nature of rock surface facilitate fast surface runoff and possibility of rainfallinfiltration is poor. From ground water resources potential view, these are have poorresource.Denudational HillThis is formed due to differential erosion and weathering so that a more resistant formationor intrusion stand as mountains or hills. These are commonly seen on the south-eastern partof the study area.Residual HillsThese are residual masses left out after prolonged weathering and denudation. In the studyarea these occur as few patches in the south. They are less dissected and non-oriented.Linear RidgeThese are linear, narrow with high relief. The trend of the ridge is in NE-SW direction. Thereoccur as small patches in the eastern part of the study area. Ground water potential of thesearea is poor.PedimentsThis is the landform characterized by gently slopping smooth surface of erosional bedrockbetween hill and plain with thin cover of soil. They occur in the north of the study area.PediplainThese are the coalescence of several pediments marked by a large area with varying lithologywith low relief. The unit occurs as largest area in the buffer zone occupying around 30% of thetotal area. Ground water potential is moderate to good.



64

Valley FillThese constitute colluvial deposits of varying lithology. These are in fact broad depressionsbetween mountains normally filled with colluvial deposits,The geomorphic units are shown in fig.no.4.1.4.1 DRAINAGEThe drainage pattern of the area is controlled by underlying geological formation andstructural features such as surface elevation, strike, folds, faults and lineaments. There aretwo major streams in the area i.e. Lant nadi and Dharlu Jhor. The Lant nadi flows in the south-east to north-east. The nadi gets its maximum flow from the central region. The Dharlu jhorflows east ward. It gets its maximum discharge from the eastern region.The drainage lines exhibits in the buffer area are in subdendritic to subparallel pattern.Though the streams and rivers in the area are controlled by the lithology and structure, slopeplays an important role in controlling the direction of flow. The drainage density variesthroughout the area with high diversity in the hilly region and low drainage density in theplains. Some of the streams are perennial in nature. But the lower order channels areephemeral.The drainage in the area is shown in fig.no.4.2

CHAPTER 5GEOLOGY

5.0 GEOLOGICAL FEATURES

The area is underlain by rock types of Eastern Ghat Supergroup of Precambraina age. The

area belongs to southern part of “ Surgically Graphite Belt” in Sambalpur and Bolangir district.

The area is mostly soil covered with sporadic outcrops of quartz-garnet-sillimanite-graphite

schist and gneisses, garnetiferous quartzite and cal-silicate/granulite of khondalite suit, their

migmatised equivalent and granite gneiss with pegmatite and quartz veins. Occasional

boulder of pyroxenite of charnockite suit of rocks are also seen at places. The general

stratigraphy of the region is given below:

Khondalite Qtz-garnet-sillimanite-graphite Schist/Gneiss

Garnetiferous Quartzite

Calc-silicate/granulite

Khondalite: The khondalite Group consists of garnetiferous sillimanite schist and gneiss with (

and also rarely without) graphite. These are interbanded with quartzites, calc granulites, calc

silicate rocks. The quartzites are grey to pink coloured with occasional garnet and fine needles

of sillimanite. Generally the typical gneissose/-schistose khondalites comprise quartz, feldspar

(usually orthoclase) garnet, sillimanite, graphite, sapphirine, spinel, cordierite, corundum and

hypersthene as accessories. Calc silicate and calc granulites occur as small pockets and lenses

consisting of diopside, calcite, wollastone, garnet, sphene, quartz, scapolite and feldspar.



68

These calc rocks are characterized by ribbed weathering with grooves and furrows. The

leptynites including the granite gneiss occur usually as bands along the contact regions of

khondalites with Charnockites and granite gneiss. Leptynites are foliated quartz-feldspar –

garnet rocks with occasional biotite and minor hypersthene with drawn out streaks of quartz

typical of leptynite.. It is felt by some workers that Charnockites are migmatized into

leptynites along well developed bands, streaks and lenses.

Charnockite Group

The charnockite Group is represented by acid/intermediate and basic varieties with rare

exceptions of ultrabasic type. Acid and intermediate types are ubiquitous in occurrence with

considerable variation in the mineralogical variation and form hill ranges aligned parallel to

the foliation of khondalites and also occur as small mounds and hillocks within the gneissic

country. These are generally hypersthene bearing quartzo-feldspathic garnetiferous

granulites. The basic Charnockites or pyroxene granulites are less common and occur as

bands, streaks and lenses of various dimensions conformably with the khondalites. At many

places this basic variety occurs also as inclusions in acid/intermediate variety. Previously, it

was thought that these Charnockites represent the original mafic igneous rocks occurring

either as sills or flows, metamorphosed into mafic granulites along with the surrounding

sediments as evidenced from swerving of foliations of the khondalites around them, ophitic

to subophitic texture, bouldery nature and prismatic fracturing. But diverse opinion was also

put forward regarding this origin.

Granite Gneisses

Granite gneisses vary from syntectonic medium grained, grey granite gneiss, migmatite,

augen gneiss to porphyroblastic gneiss. The gneissic variety is rich in biotite and essentially

contains garnet and show effect of contact metamorphism with khondalites with formation of

spinel and corundum at the contact. The porphyroblastic type is rather limited in occurrence.

Discordant and concordant bodies of pegmatite and vein quartz traverse the gneissic country

.



69

5.1 RECENT

The quaternary formations include laterite and alluvium. Laterites occur as capping over the

khondalite suites in the hill ranges and also over the granites and granite gneisses in the

valleys and pediment areas. The alluvium comprises sand silt and clay occurs in the close

vicinity of the major drainage channels. A thin sheet of laterites ranging in thickness to a

maximum of about 1.5m is observed in sporadic patches. These are porous and hence aid

percolation to ground water.

5.2 LOCAL GEOLOGY

On the basis of trial pits it is inferred that there are three nos. of narrow bands of khondalite

schist sand-witched between khondalite migmatite. The overall trend of this schist is N300 S

and dip is around 160 in the direction of S600E.

Graphite occurs as disseminated flakes or as segregated veins or pockets in the schist. All

along the strike continuity of the schist, the graphite concentration varies owing to its nature

of occurrence and it is at places concentrated enough to become economically viable for

CHAPTER 6

AQUIFER SYSTEM

6.0 HYDROGEOLOGY

The study area is underlain by varied rock types with wide variation in hydrogeological

characteristics. Depending upon the characteristics the area is classified broadly into two

hydrogeological units.

Consolidated formations

Unconsolidated formations

6.1 CONSOLIDATED FORMATIONS

Rock types of Eastern Ghat Super Group constitute the consolidated formations. These rocks

are devoid of primary porosity and are usually very hard and compact in nature. The

secondary porosity in the consolidated formations developed as a result of weathering which

is limited to few meters from surface. Secondary porosity also developed in the form of

fracturing due to major and minor tectonic movement. The fractures form the conduits for

movement of groundwater as also act as reservoir of groundwater. This fractured and jointed

rocks when interconnected form potential aquifers, which sustain limited to moderate yield.

Groundwater occurs under water table conditions in the weathered residuum while it occurs

under semi-confined to confined conditions in the fractured and jointed rocks. The

hydrogeological properties of individual rock types are described as below:

6.1.1 Khondalite

Khondalites are represented by quartz-garnet-sillimanite ±graphite schist and gneiss with calc

silicate and garnet as occasional occurrences. These rocks are well foliated and have

developed good to moderate weathering. The thickness of weathering varies from 5 to 25

meters. This weathering layer is a good repository of ground water resources. Ground water

development is possible by tapping zones down to 12 meters by means of dug wells. Ground

water also occurs in deep fractures. One to two sets of saturated fractures are encountered in



72

between 50 to 150m depth. The yield of borewells tapping these fractures varies from 0.3 to

5 lps.

6.1.2 Charnockites

These formations are of very much-restricted occurrences in the study area. Due to paucity of

joints and fractures, the thickness of weathering in these formations is limited to 10m. The

depth of open well varies in the range between 5 to 10m. The average yield of dug wells

ranges between 5 to 10 m3/day. The discharge of borewells tapping deeper saturated

fractures within depth range of 150m ranges from negligible to 2 lps. Due to the compact

nature and less weathering, ground water prospect in charnockite is not good.

6.1.3 Granite gneissesAs shallow aquifer: Ground water occurs in pheratic condition. The thickness of the

weathered zone is generally more in topographic lows and undulating plains than in the high

land areas. The weathered residuum ranging in depth from 3.25 to 9.85m below ground level

constitute the shallow aquifer zone. On weathering these rocks produce sandy granular

material and their water holding and transmitting capacity depends on the percentage of

kaolin present. The weathered zone forms the main repository of ground water and aids in

circulation of ground water through interconnected fractures and fissures to deeper fracture

zones.

As deeper aquifer: These rocks have well-developed joints and fractures which constitute the

deeper aquifer zone. Ground water occurs in semi-confined to confined condition. There are

generally two to four sets of fracture zone within 160m depth below ground level. The

discharge of the wells within 160m bgl depth is negligible to 25 lps. This variation in yield

depends on topographic setting, proximity to the major lineaments, thickness of weathered

residuum and number of saturated and interconnected fractures encountered.

6.2 UNCONSOLIDATED FORMATIONSAlluvium: Recent alluvium occurs as thin discontinuous patches along prominent drainage

channels. The thickness of the alluvial deposits varies from 5 to 10m and form potential

shallow aquifers. The specific capacity of the dug wells varies from 336 to 446 lpm/m draw

down. These sustain development of ground water through open wells.



73

Laterite: Laterites occur as capping over the older formations and are tapped through dug

wells. However they do not form good aquifer. But due to their porous nature, they allow

higher percolation of atmospheric precipitation into ground water.

A total 14 nos. of observation wells were established in the study area. The water level of the

wells were monitored during the pre & post-monsoon 2012. The location and details of the

wells are given in the table no.7.1 and 7.2 and shown in fig.no.7.1.

7.1 PRE-MONSOON, 2012 DEPTH TO WATER LEVEL.The pre-monsoon depth to water level varies in the range between 5.10m.bgl and

9.028m.bgl. Maximum water level was observed at Ramod which was 9.02m.bgl. The depth

to water level contour map was prepared and shown in fig. 7.2. The map depicts that waterlevel in major part of the area lies between 5 and 7mBGL. Water level is shallow in the north,

west and south-western part of the area which is in between 5 and 6m and deep in the east

and south-east which lies between 6 to 9m BGL.7.2 POST-MONSOON , 2010 DEPTH TO WATER LEVELThe post-monsoon depth to water level varies in the range between 2.33m.bgl and 6.68m.bgl.

Maximum water level was observed at Ramod which was 6.68m.bgl. The depth to water levelcontour map was prepared and shown in fig.7.3. The map depicts that water level is shallow

in the north, west and south-wesern part of the area which lies between 3.0mbgl and

4.0m.bgl. Water level is deep (5.0-6.0mbgl) in the east part of the area.7.3 WATER LEVEL FLUCTUATION (PRE TO POST-MONSOON)All the observation wells show rise in water level during post-monsoon period. The rise in

water level is in the range of 0.8m. to 4.42m. Maximum rise in water level was observed at

Goendamal which was 4.42m. Fluctuation contour map was prepared and shown infig.no.7.4.The map depicts that central part of the study area show maximum rise in water

level in the range between 3 to 4m.

7.4 WATER TABLE ELEVATIONWater table elevation map has been prepared and shown in fig no.7.5. The map depicts that

water table elevation varies from 350m to 300mamsl. Water table is at higher elevation in the

south central part and ground water flow direction from south-central to south-east, northand north-west direction.

CHAPTER 8PUMPING TEST

8.0 AQUIFER CHARACTERISTICS

Aquifer characteristics are necessary in order to assess the ground water potential of the area.

It is essential to know aquifer parameters such as yield, transmissivity and storativity. For this

purpose one aquifer performance test was conducted. Static water level was subtracted from

the respective pumping water level data recorded to obtain drawdown. The computed value of

drawdown and time were plotted on a semi log paper and analyzed by applying Jacob’s

Straight Line formula mentioned below-

Transmissivity (T) = (2.30X Q) / (4 ∆S)

Where Q is the yield of well recorded during pumping

These data along with respective analysis and plotting of data on semi-log graph sheet are

shown in fig.no.8.1. Basic data of APT is given below:

CHAPTER 9

MINING DEWATERING

9.0 MINE DRAINAGE

De-watering in Open Cast Mining Pits of Goendamal Graphite Mines

The Goendamal Graphite Ore Mines spreads over an area of 63.771 hectares (157.58 acres) of

land. The surface elevation of mining lease area varies between 326m.amsl and 348m.amsl.

Presently mining is proposed to be carried out in one Quarry (pits) such as Quarry No.5 only.

Water Table elevation ( based on the water level data of dug wells tapping phreatic aquifer &

measured during post-monsoon,2012) surrounding the Mines varies in between 340 and

330m,amsl. The ground water flow direction is from south to north. The elevation map is

shown in fig.9.1. This is a regional water table elevation map. But to get a precise picture of

ground water intersection the piezometric head of the piezometer in the premises of the

mining lease area has been taken in to consideration.

Fig.9.1: Water Table Elevation, Post-Monsoon, 2012 Surrounding Mines (m.amsl)



86

Piezometric head measured in the piezometer established in the mining lease area (in the

premises of the site office) is as below:

Month Head in m.amsl

May, 2012 324

August, 2012 330.75

Nov, 2012 331.61

The present pit bottoms of Quarry-5 stands at 331m.amsl and the ultimate Pit bottom at the

end of the mining plan is 322.5. Hence mining activities will intersect water table during

monsoon and upto few months after monsoon. The intersection also depends upon the

progressive pit bottom.

The groundwater level must be pulled down to create dry conditions in the mining area so that

the generally low strength aquifer sequence material can be safely excavated. Mine dewatering

is usually undertaken for a variety of geo-technical (material strength considerations), mining

and safety reasons also.

Water Flow Direction



87

The main objective is to find out the total volume of ground water which needs to be

removed from the Pits for safe mining operations.

9.1 GROUND WATER INTERSECTION

The groundwater inflow to a mining excavation is mainly a consequence of the interaction of

groundwater system, hydrogeological characteristics of the rock mass and the mining

geometry. The water inflow regime is determined by the incision of one or more aquifers by the

mining exaction and the relative hydrogeological characteristics of the various aquifers.

The groundwater inflow in the vicinity of mining excavation can be estimated by one of the

following techniques.

Equivalent flow approach

Two-dimensional flow equations

Numerical techniques incorporating the Finite Element method, Finite Difference

Method or the Boundary Element Method

The groundwater inflow equations use both linear flow as well as non-linear flow conditions.

The effect of turbulence results in the reduction of inflow quantities because of the energy loss

in the turbulent flow. The method outlines the two-dimensional flow technique of estimating

ground water to surface excavations using both steady state and transient state equations for

unconfined and confined aquifers. This approach provides a simple method of predicting first

order estimates of ground water inflow to mining excavations and provides a factor of safety by

slight over-estimating the inflow.

The complexity of the relationship between aquifer type, aquifer characteristics, flow regime

and mining excavation often complicates mine water inflow prediction. The flow regime

depends on the type of conducting medium. In an unconsolidated sedimentary sequence where

groundwater movement is through inter-granular pore-spaces, flow is essentially linear. On the

other hand, in a rock sequence in which it is the secondary processes like fracturing and faulting

that provide the conducting medium, flow is predominantly non-linear. Surface mining

excavation serves as a natural groundwater discharge point. Near the excavation, there is

invariably, a vertical component of flow and high hydraulic gradient which often leads to

turbulent flow and negates analysis by Darcy’s Law. Non-linear flow equations are therefore



88

valid. The rate of flow is generally computed from equations which relate the hydraulic head

loss in and flow of groundwater through the porous geological strata. Prior knowledge of

aquifer hydraulic characteristics and pit geometry is necessary. The aquifer parameters are

obtained from detailed hydrogeological investigations of the mine site and pit geometry from

the mine plan.

The analytical approaches for estimating groundwater inflow to surface mining excavations are

based on drawdown theory.

9.1.1 Equivalent Well Approach

This approach assumes that dewatering of the surface mine is carried out by use of an

imaginary pumping-out borehole ( fully penetrating the entire saturated thickness of the

aquifer) from which water is pumped out at a uniform discharge rate in order to lower the

piezometric level of the aquifer to below the mining horizon at the mine boundary. Input

parameters for equations developed in this approach are aquifer characteristics (Transmissivity,

Permeability, Storage-Coefficient and Leakage Factor) and mine geometry. Normally the mine

excavation is envisaged as large diameter well. Where the mine has the shape of a square or

rectangular as is the case in most strip mine, than, an equivalent radius for the well is calculated

using the equation given by (Mansur and Kaufman,1962).

r = [ - ] ( Y.W)

Where Y= length of the mine, m

W=width of the mine, m

r= equivalent radius, m

Dudley (1972) discussed various methods of approximating a mine model to an equivalent

cylindrical well and estimating input parameters for the equivalent well model. The notations

used in the equations in this approach are defined as follows:

D= drawdown (m)= (H-h)

H= original height of water table or piezometric surface above mine level (m)

h= piezometric head at a specific point in time (m)

constant rate Q to reduce the head by D.

been calculated taking the assumed progressive pit bottom and is shown in the table 9.1. The

9.2 USE OF PIT DE-WATERED WATER

The pumped out pit water is being put to gainful uses. Goendamal Graphite Mines requires

water mainly for dust suppression, green belt development and for drinking and domestic uses

for colony, drinking for mining site and uses in site office. Pit water will be used for dust

suppression and green belt development only. On an average 54 m3/day of mining de-watering

water will be available.



92

The amount of water required for dust suppression will be 20 m3/day and for green belt

development it will be around 10 m3/day. The balance water of 24 m3/dat will either be stored

for use for the above purposes during non dewatering period or will be used for agriculture.

CHAPTER 10GROUND WATER QUALITY

10.0 CHEMICAL QUALITY OF GROUND WATER

In order to assess the chemical quality of ground water in the buffer zone,

ninenos.ofwatersampleswerecollected and analyzed. The table 10.1 shows the quality of

ground water in the area.

A perusal of the table no.10.1 indicates, the distribution of various constituents vary greatly in

the area. Concentrations of the above parameters are well within the permissible limits as per

the BIS standards.

pH of ground water samples varies from 6.7 to 7.3 indicating slightly acidic nature of the water.

The maximum permissible limit for pH as prescribed by B.I.S (1991) in drinking water supply is

6.50 to 8.50. The ground water has pH values within prescribed limits and suitable for drinking

purposes.

The results of chemical analysis of ground water samples indicate that there is less variation in

conductivity in the area. The EC value of ground water varies between 220 and 375 micro-

mhos/cm at 250c. The range of electrical conductivity values shows that the ground water of

the area is fresh.

The major sources of chloride in ground water are from rainwater, evaporite deposits and

seepage from sewage and industrial effluents containing common salt. The chloride

concentration in ground water varies from 30 to 55 mg/l indicating the quality of water within

this aquifer is portable.

The main sources of nitrate in ground water are atmospheric precipitation, geological deposits,

industrial wastes, sewage and animal wastes and agricultural sources. The nitrate concentration

in shallow ground water has been recorded from 2.5 to 4.6mg/l. The nitrate concentration in

ground water in the area is well within the permissible limit of 100mg/l as prescribed by

BIS,1991.

The fluoride concentration in the area lies between 0.03 to 0.08mg/l. The fluoride

concentration is within the permissible limit as prescribed by BIS, 1991.

The ground water samples of the area show that water is fit for drinking as well as for domestic



94

purposes.

CHAPTER 11DYNAMIC GROUND WATER RESOURCES

Rainfall is the principal source of ground water recharge in the study are/buffer zone. For

estimation of ground water resources and stage of ground water development in the buffer

zone, GEC (Ground Water Resource Estimation Committee, 1997) norms have been adopted

and are described below.

11.1 GROUND WATER RECHARGE

a) Monsoon Ground Water Recharge

I) Based on Rainfall Infiltration Method

Total Area : 314 sq.km

Area suitable for recharge : 295sq.km

Average Rainfall : 1534.5 mm

Infiltration factor : 12%

Annual Recharge : 54.30 MCM

II) Based on Water Table Fluctuation Method

Area suitable for recharge : 295 sq.km

Mean water level fluctuation : 3.5m

Specific yield : 4%

Maximum Ground Water Recharge : 41.3 MCM

The ground water resource estimated by Water table fluctuation method is less. Therefore as

per the norms of GEC, it is to be adopted.

b) Recharge through other sources

Recharge through other sources primarily constitutes recharge through surface water irrigation.

Return recharge from surface water irrigation is estimated to be 30% of the applied water for

irrigation. As per the district irrigation department, about 898 ha. Of land is irrigated in the

study area. If the gross irrigation requirement is taken as 50 cm/ha, total applied water will

work out to be 449 Ham. The return seepage will be 30% of 449 Ham i.e. 134 ham or 1.34

MCM.



96

c) Hence annual ground water resources will be

41.3 MCM+1.34 MCM

=42.64 MCM

11.2 GROUND WATER DRAFT

Ground water is mainly used for domestic, irrigation and industrial need. To estimate the

ground water use, Census data of 2001 have been used for population and irrigated area.

Draft for Drinking Use

Population using groundwater as drinking water : 37635

Per Capita : 70 lit/day

Annual Ground Water Use : 0.00263 MCM

Irrigation Use

About 83 ha of land is being irrigated through ground water. Considering 50 cm/ha of ground

water use, total ground water need for irrigation works out to be 0.415 MCM.

Industrial Use

Several industries are in the process of being set up in the study area. The industrial use can be

taken to be about 3 MCM

Total Ground Water Utilization

0.002MCM+ 0.415 MCM+3 MCM

= 3.417 MCM

Ground Water Balance

Annual Resources =42.64 MCM

Annual Utilisation =3.417 MCM

Balance GW=39.223 MCM

11.3 STAGE OF GROUND WATER DEVELOPMENT

The stage of ground water development in an area is taken as the ratio of Gross annual draft for

all uses to the total utilizable ground water resource or net annual ground water availability

Thus the stage of ground water development ( in %) in the buffer zone is



97

Net Ground Water Draft

= ----------------------------- X 100

Net Ground Water Availability

= (3.417/42.64 )X 100

= 8.01 %

The unit of assessment as per GEC norms are categorized for ground water development based

on two criteria.

i. Stage of Development

ii. Long term trend of pre & post monsoon water level

Since the buffer zone represents an area where stage of development is 8.01 % and there is no

long term decline of pre & post monsoon water level , the area is categorized as safe.

CHAPTER 12CONCLUSION

Goendamal Graphite Ore Mines of the lessee Sh.Natwarlal Agarwal is located in Goendamal

village in Turekela block of Bolangir district Odisha State. The mining lease area is spread over an

area of 63.771 hectares of non-forest land. The Mining Lease area falls in the Survey of Indiatopo-sheet no. 64 L/14 and is bounded by North latitude 20034’07” to 20035’20” and East

longitude 82046’10” to 82046’34”.

There are 5 nos. of quarries i.e. quarry no.1, 2, 3, 4 & 5. But mining will be resumed in quarry no.5 only with the annual production of 15000 tonnes. The mining will be carried out through open

cast manual mining methods.

The climate of the area is tropical monsoon climate with average annual rainfall of 1094mm with

annual maximum and minimum temperature of 480C and 120 C respectively.The area is characterized by geomorphic features such as denudational hills,valley fill, linear

ridge, pediments,residual hills, pediplain and structural hills. The area is drained by river Lant &

Dharlu jhor.The entire study area is underlain by rock types of eastern Ghat Super Group of Pre-Cambrian

age. The rocks constitute Khondalite, Charnockite and Granite gneisses. The lateritic formations

occur as cappings at discontinuous patches.The pre-monsoon depth to water level varies in the range between 5.0m.bgl and 7.0m.bgl.

The post-monsoon depth to water level varies in the range between 2.3m.bgl and 6.7m.bgl.

The stage of ground water development of the study area has been calculated to be 8.01%.The ground water samples of the area show that water is fit for drinking as well as for domestic

purposes.

The surface elevation of mining lease area varies between 326m.amsl and 348m.amsl.the surface

elevation at quarry -5 is 340mamsl. The present bit bottom of quarry -5 lies at 331mamsl andultimate pit bottom will be 322.5m as per the latest approved mining plan. The piezometric head

measured in the lease area varies in the range between 324m amsl during pre-monsoon to

332.5mamsl during monsoon. So mining activities will intersect water table during monsoon andwith progressive mining , water table will be intersected even after monsoon. De-watering of

mining pit is necessary for safe mining. The quantum of probable de-watering water has been

estimated to be 54 m3/day. The pit de-watering water will be used for dust suppression, greenbelt development. The balance water will be either stored for use during non-dewatering period

or for agriculture.

Risk Assessment and Disaster Management Plan

Risk is the probability of the harm or likelihood of harmful occurrence being released

and its severity. Environmental risk is a measure of the potential threats to the environment,

life and property and which is more likely to happen in the mining activities. All the type of

developmental activities like mining, industries, developmental projects may face certain type

of hazards which can disrupt the normal activities abruptly and lead to disaster like fires,

inundation, failure of machinery, explosion. A risk assessment has been carried out and the

disaster management plan formulated with an aim of taking precautionary measures to control

the hazard propagation and avert disaster and to take such action after the disaster, which

limits the damage to the minimum.

Objectives

The objectives of environmental risk assessment are governed by the following, which

excludes natural calamities:

a) To identify the potential hazardous areas so that necessary design safety measures can

be adopted to minimize the probability of accidental events.

b) To identify the potential areas of environmental disaster which can be prevented by

proper design of the installations and its controlled operation.

c) To manage the emergency situation or a disastrous event, if any, from the mining

operation.

The major hazards related to the mining activities are as follows:

Open cast bench slope failure

Accident due to fall of quarry sides

Accident due to machineries

Accident due to explosives

Electrical hazards



133

Environmental Risk Evaluation

From environmental hazards point of view for the mining activities and processing of

ore in various point of work the relative risk potential analysis is made on the following three

factors:

Likelihood of occurrence

Likelihood of detection

Severity of consequence

Each of these factors is graded and compiled to determine the risk potential. The factors

governing the determination of relative risk potentials are presented in the table.

Determination of Risk Potential

A B C

Likelihood of occurrence Likelihood of detection Severity of consequence

Criteria Rank Criteria Rank Criteria Rank

Very High 5 Very High 1 None 2

High 4 High 2 Minor 4

Moderate 3 Moderate 3 Low 6

Low 2 Low 4 Moderate 8

Very Low 1 Very Low 5 High 10

Risk Potential (Rp) = (A + B) x C

Based on the above stated criteria for assessing the risk, each probable event has been

evaluated by addressing several questions on the probability of event occurrence in view of the

in-built design features detection response, operational practice and its likely consequence.

The major risk associated with the project activities are as follows:

Open Cast Bench Slope Failure

The bench slopes are to be monitored regularly by sensitive instruments at precise level

at regular intervals to check for any possible ground movement. A well-developed drainage

system over the leasehold area is to ensured & check the water flows out of the lease area.



134

Probable Reasons of Accident

Accidents Due To Fall of Sides

Failure to make and keep the quarry sides secure by proper benching, sloping and

keeping benches of adequate height and width.

Undercutting so as to cause dangerous covering.

Inadequate nos. of competent persons for carrying out statutory inspections.

Lack of supervision.

Accidents Due To Transportation Machinery (Shovels, Trucks And Dumpers) During reversal operation

Unauthorized driving of vehicles (mostly by helpers)

Unauthorized riding of vehicles

Attempt to ride moving vehicles

Overloading

Driving vehicles in a intoxicated stage

Vehicles moving in steep gradient or on benches of inadequate width

Other Than Transportation Machinery

Use of sub standard equipments

Attempt to clean moving parts of machinery

Non-provision or removal of guards from moving parts of machinery

Accidents Due To Use of Explosives

Fly rock throw due to blasting

Inadvertent handling of explosives

Miscellaneous

Electrical hazards

Small scale fires

Disaster Management Plan

To address the probable risk associate with the project activities and to minimize the

risk in different stage the disaster management plan has been framed by the project

implementing agency. The following precautionary measures shall be taken to prevent any kind

of disaster in the mining operations:

Top edge of opencast workings shall be kept properly fenced off to prevent failing

down of man and animals.

At the final stage, the workings shall be fenced with masonry wall (of not less that

0.13m thick and 1.2m high with a parapet top).

The sides of excavation and the height and width of benches shall be properly

maintained as per mining regulations.

Quarrying shall be done from top downwards. No overhand will be allowed.

Special attention and requisite precautions shall be taken while working in areas of

geological weakness like existence of slip, fault.

Regular dressing of bench sides to ensure safety of workers employed with in 5m of

working face.

Provision of safety belt or rope while persons are at work at the quarry sides or

benches from where there are chances of falling down for more than 1.8m.

Spoil banks not to be retained by artificial means at an angle of repose in excess of its

natural angle.

Drafting and implementation of preventive maintenance schedule for various kinds of

machinery deployed in opencast workings.

Provision of maintenance of properly laid haul roads with parapet wall fencing or

guards and road signs at strategic points.

Precautions against danger while traversing dumpers, excavators. by installing audio-

visual alarms and appointment of spotters.

Transportation of ore within mine workings by vehicles under the direction, supervision

and control of Mine Management only.

Proper maintenance of vehicles and weekly examination by an engineer and daily

examination by a competent person.

Training and retraining (at specified interval) of the machinery operators.

Use of controlled blasting techniques. 500m-radius danger zone to be followed strictly.



136

Provision of blasting shelters – properly constructed and maintained.

Blasting danger zone will be identified and indicated to the concerned mine people and

nearby locality to avoid inadvertent trespassing

Whistle will be blown an the time of blasting not to enter into the blasting danger zone

A guard will be employed to prevent pilferage or theft and to keep the explosive in safe

and secure

Adequate maintenance of electrical equipments.

Adequate illumination after daylight.
