EXECUTIVE SUMMARY

Demand for river sand is enormously increased in building construction, good transport

road formation and in infrastructural developments. The river sand is stated vanishing

from the river beds besides causing natural and environmental hazards in surrounding

areas due to illegal and unsystematic way of mining without Proper Mining plan.

Systematic, Scientific and “Eco-Friendly “Mining/ Desilting of river sand will helping in to

avoid flood and also meet the sand requirement in building construction, good transport

road formation and in infrastructural developments. Hence west Bengal Govt. is

sanctioning the sand mining lease.

The Kangsabati or Kasai River is a major river system in the study area. It originates from

Chhotonagpur plateau and flows in the district Paschim Medinipur and conjoined with

Keleghai and falls into the Haldi River near Mahishadal. The river is navigable during

rainy season. River Kumari in Bankura and Cossye from Kapastikri in Paschim Medinipur

are the main tributaries of Kasai River. The river carries a large amount of silt causing

silting up the channel.

5.0 PHYSIOGRAPHY, DRAINAGE & CLIMATE:

On the basic of the characteristics of the districts, the entire Midnapore district (Purba

and Paschim) has broadly been divided into two natural divisions –the western upland

including undulating lateritic Rarh plain and the eastern Gangetic alluvial plain along

with southern maritime tract. It is assumed that a metalled road passing from Raniganj

to Cuttack through undivided Midnapore district that cut across the district north to

south is the approximate boundary line of these two natural divisions. Physiographically,

the region has been sub-divided into three macro-regions and five micro-regions. The

macro-regions are:

a) The Western Upland

b) The Rarh.

c) The Plain (Deltaic and Coastal).

The micro-regions lies within these macro-regions are:

i. Medinipurupland

ii. Silaiplain

iii. Lower Kasai plain

iv. Contaiplain

v. Digha coastal plain

Lower Kasai plain:

Kasai is the main river in this region. The region extends over both the side of the Kasai

River. Being the largest plain area of undivided Midnapore district, the upper eastern

part is experienced with the deltaic nature while the lower northern part experiencing

the tidal influences; ebb and flow is very much active in this region. It is a long

depressed area characterized by low laying tract of alluvium. This is formed due to the

assimilation of the deltas of Kasai and Silai in the north-west portion which is triangular

in nature. The rate of alluvial deposition is very high as for the river bed of Kasai is

totally lost her navigability.



General slope is noticed in this area is from NW-SE a sloppy undulating terrain. The flow

of the water is SE direction. Most of the River bed area covered fine grain to coarse

grain sand with rocky pebbles at places & there is no vegetation except grass at places.

The district is characterized by tropical day climate with a hot summer. The daily

maximum temperature in the hot summer is about 40 0cand annual rain fall is ranging

fron1400 -1800mm.

6.0. GEOLOGY OF THE AREA:

a) Regional Geology:

The terrain characteristic of the district (undivided Midnapore) is lateritic in the western

and north-western part while in southern and south-eastern part it is gradually changing

with alluvium deposit of Gangetic delta. In north-west and western portion is hilly

upland and several ridges are formed where micaceous schist carved out from the

beneath of lateritic outcrop. Grey and bluish-grey micaceous schists are found in the

ridges. The hills are separated by valley in an irregular manner. The hills are composed

of hard grey and grayish-white gritty quartzite whereas blue slater and traps are found

in the valleys.

The lateritic rocks are present in the undulating plain surface and it covers a large area.

The lateritic rocks area is slightly elevated from the adjoining alluvial plain. The gravelly

structure is found in most of the areas. The lateritic gravel and laterite covering areas

are characterized by dry, parched and stony soil which is not suitable for crop

cultivation. The upper laterite often enrooted by conglomeratic and pebbles of quartz or

somewhere it rests upon grayish white and reddish clay, soft soapy and felspathic rocks.

The clay beneath down the lateritic gravels is slightly saturated with iron. Most aberrant

phenomenal feature of geology of the district is the long and vast lateritic sheet found

into the dip of adjoining Gangetic plain and also the dip of western upland.



b) Local Geology (Tectonics and structural behavior of rocks, description of formation,

lithology of catchment area,).

Most of the area is covered by ordinary river sand deposited decade back. The other

rock formation in area is alluvial rocky upland and undulating lateritic upland these

formations undergo series of metamorphic cycles, like weathering, erosion,

transportation and deposition of sand material.

The geological parameters / features of the ore body as obtained from the field mapping

and exploration studies reveal the following.

Length of the Deposit (Lease Area.) : 450-500 m

Width of the Deposit (Lease Area.) : 160-170m

Depth of the ore body : 1.5m-2 m.

A Surface Geological Map & Section showing the different litho units is mapped and the

cross-section showing the disposition of the different litho units are marked and

enclosed as Plate No. 5.

C ) Replenishment Study.

i) Origin and Control of mineralization

Sediment dispersal and accumulation patterns are governed by three basic effluent

forces and by tide- or wave-induced processes. Neglecting modifications by tides or

waves, effluent behavior and consequent depositional patterns depend on the relative

dominance of (1) outflow inertia, (2) turbulent bed friction seaward of the mouth, and

(3) outflow buoyancy.

The final source to be discussed is the alluvium of the Plains. Sheet and rill erosion of the

low gradient surface of the Plains is surprisingly high; between 500 and 1000 t km–2 yr–

1 , with ravine (gully) lands yielding ~ 3000 t km–2 yr–1 along river terrace margins

14,36. But there are no estimates of the Sediment Delivery Ratio for these parts of the

Ganga Basin.



iii )Geomorphology

Geo-morphologically, the area represents flat topography with regional slope. The

district lies in the Ganges delta Plain. The Ganges delta consists of the whole

of Murshidabad district, Nadia, Kolkata, Hooghly, and Howrah and the northern part

of North and South 24 Parganas. River Ganges passes through this vast area and divides

into three distinct parts – the old delta, the mature delta and the active delta.

iv) Climate Zone, Rainfall, Drainage Pattern

A) Climate Zone

The area is experienced by a great variation in climatic characteristics. The climate is

very much tropical and exercising monsoonal characteristics with variations in micro-

regions. The climate of the northern and western part of the area is being characterized

by arid climate having a vicious dry heat in summer, a short winter season and

moderately rainfall. The climate of eastern and southern part is different in nature;

characterized by hot and humid climatic condition. The seasons are however well

marked for the entire area.

• Summer season – (March to May)

• South west Monsoon season – (June to September)

• Post-Monsoon season – (October to November)

• Winter season – (December to February)

B) Rain fall

The average annual rainfall occurs in the area is 1525.5 mm which is very much variable

in nature from place to place. Most of it occurs during monsoonal period. At least 74.0

percent of the total annual rainfall occurs in monsoonal period. The average annual

range of temperature varies from 25.5 °C to 38.6°C in Purba Medinipur whereas in

Paschim Medinipur it varies from 39.0°C to 10.0°C. The average annual rainfall occurs in

Purba Medinipur is 1697.0 mm whereas in Paschim Medinipur it is 1550.0 mm.

C ) Drainage Pattren

The Kangsabati or Kasai River is a major river system in the study area. It originates from

Chhotonagpur plateau and flows in the district Paschim Medinipur and conjoined with

Keleghai and falls into the Haldi River near Mahishadal. The river is navigable during

rainy season. River Kumari in Bankura and Cossye from Kapastikri in Paschim Medinipur

are the main tributaries of Kasai River. The river carries a large amount of silt causing

silting up the channel.

iv) Sedimentation study.

The catchment of the combined Ganga–Brahmaputra rivers is 1.656 ´ 106 km2 in area,

yields ~ 1000 ´ 106 tonnes/yr of suspended sediment at a point ~ 200 km from the ocean

in Bangladesh2,3 (~ 8% of the total sediment load reaching the global oceans), and

appears to be the highest suspended sediment load of any river system in the world.

The Ganga–Brahmaputra rivers contribute almost all of the sediment making up the

Bengal Delta and Submarine Fan, a vast structure that extends from Bangladesh to south

of the Equator, is up to 16.5 km thick, and contains at least 1.13 ´ 1016 tonnes of

sediment4 accumulating over the last 17 ´ 106 years at an average rate of 665 ´ 106 t/yr.

From about 0.9 ´ 106 years ago, the rate of accumulation in the Bengal Fan has

increased by a factor of 4.5 from the previous 6 ´ 106 years, coincident with global

cooling and drying. The Fan has buried organic C at a rate since the early Miocene of ~

1.1 ´ 1012 mol/yr, representing between 10 and 25% of the total global burial flux of

organic carbon during this period.

Silt sediment in the River during the month of May to June 2016, a daily reading showed

0.8 cm increase in the deposit of silt inside the reservoir connected to the river. The

sediment level is higher and the same does not get washed away with low tide as the

water in the reservoir does not have current therefore allowing the sediment to settle

down. The reading was carried out during low tide. The river water was allowed to enter

in to private land. The study measuring sediment level is ongoing; the same shall be

concluded by October, 2016.



a) Estimation of Geological Reserve & Grade

The parameters considered for estimation of reserves.

a) The total Sanctioned area for Mining of River Sand 7.717 Ha

b) The total area proposed for Mining of Brick earth/river silt is 7.360 Ha or 73600M2

c) Depth of the Mining allowed is 2.0m from the ground level.

d) Bulk density is taken 2.5.

Geological Reserves of river sand are tabulated below.

Total area in M2

Depth of pit In Mtr Volume in M3 Bulk Density Total MT

73600 2.0 1,47,200 2.5 3,68,000

Note: Every year silt will be removed and allow excavated pit for sedimentation. The

sedimentation study reveals that every day 0.8cms of silt will be filling in the proposed

area, hence mining activity only for four months rest 8 months allowed for

sedimentation of silts.

7.0. METHOD OF MINING IN DETAIL:-

a) Category of mine (A/B1/B2)- B2 :

The proposed River Silt is >than 5.0 Ha, hence this project comes under Category-B1.

b) Year wise development plan.

The sedimentation in every year is about 1,40,000 M3. Year wise production for plan

period is tabulated below.

Year Area in M2

Depth/Bench Height Area in M3 Bulk Density Total in MT

1st Year 70000 2 1,40,000 2.5 3,50,000

2nd Year 65000 2 1,30,000 2.5 3,37.500

3rd Year 65000 2 1,30,000 2.5 3,37.500

5th Year 65000 2 1,30,000 2.5 3,37.500



c) Extraction methods:-

Presently the ordinary River sand mining is working with conventional open cast with

bench system method with manual mode of operation.

It is only a small-scales and mining. The extraction of sand is being done by manually

with simple hand tools such as shovel pans and crowbars & some place Slurry pumps

will be used to extract sand. This activity followed by sorting of pebbles by manually or

by screening device.

Initially it is proposed to sub level bench method keeping a sub bench height of 1.0m

and at the final stage all the sub benches will merge. The maximum bench height is kept

2.00 m and Pit Slope will be maintaining 65 degree at ultimate stage.

Proposed Project will lift River sand i.e. 1,30,000M3 or3,37,500 MT/annum from the

lease area of 7.717 ha, river sand is having huge demand in construction projects,

infrastructure development in the state.

d) Drilling& Blasting

No Drilling & Blasting is required since it is river sand extraction manual only.

e) Excavation and Transportation of Materials:

Subsequent to the extraction of sand is being done by manually, and sorting of pebbles

by manually or by screening device, will be lode manually or by small loading Machinery

(small Capacity Excavator) into trucks Tippers of 10 tones capacity. The loaded material

is transported to the various places for Building construction, road construction places

f) Details of employment

Since it is only small scale River sand mining, and the Mining is being done by scooping

of sand manually.



Local labors shall be engaged from the nearby villages, districts and neighboring states

like Bihar, Jharkhand and Odessa for digging / desilting of and loading / handling of river

sand. The mining project shall provide direct employment to the population nearby.

Total No of labors Skilled ,Semi-Skilled un Skilled required is 10 members,

8.0. STACKING OF MINERALS AND WASTE:

No solid waste is generation other than negligible quantity of screening debris / soil

material will collected and same will be used for Internal and external roads formation

purpose, hence The unit generates zero solid waste during production.

9.0. LOADING & TRANSPORTATION OF MINERALS AND WASTE:

It is only a small-scales and mining. The extraction of sand is being done by manually

with simple hand tools such as shovel pans and crowbars & some place Slurry pumps

will be used to extract sand. This activity followed by sorting of pebbles by manually or

by screening device

River sand mining and loading will be done manually/JCB and the same is transported to

the adjacent high land by overhead load. or by engaging transportation vehicles on

contractual

10.0 ENVIRONMENTAL MANAGEMENT PLAN:

The mining operations in the study area need to be intertwining with judicious

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

assimilative capacity of the study area is the maximum amount of pollution load that

can be discharged in the environment without affecting the designated use and is

governed by dilution, dispersion and removal due to natural physio-chemical and

biological processes. The Environmental Management Plan (EMP) is required to ensure

sustainable development in the study area.

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

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



statutory requirements of gaseous emissions, wastewater discharge characteristics,

noise levels etc. for environmental management purpose in connection with the mining

and its related activities in the study area.

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

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

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

regulatory requirements on environmental and socio-economic aspects.

Environmental Management Plan giving the environmental protection measures at

mining to meet the stipulated norms, are as detailed.

a) Air Environment

As the proposed mining involves only scooping of River sand from the Delta (surface) of

the river bed, the quality of the air will not be altered by this. As it is a manual mining

using simple instruments / tools, there will not be emissions into the atmosphere. The

surrounding area will not have any change in the air quality due to the proposed mining

activity.

The change in air quality will only be due to vehicles used for transportation of River

sand the no. of vehicles per day will be about 12 to 15 considering River sand Desilting/

excavation in general shift 8 hrs duration. All the vehicles used for transport of River silt

will be “environmentally compliant” and the emissions of vehicles will be in accordance

with the MOEF norms. Existing roads are adequate for the handling of this additional

traffic.

The following measures will be adopted in mining to eliminate the fugitive dust

emission.

Proposed Mitigating Measures:

The dust generated during the vehicular movement will be controlled by spraying of

water on roads for which water tanker fitted with sprayer are proposed. Over loading of



trucks and consequent spillage on the roads will be avoided. Measures such as covering

with tarpaulins over the loaded material will prevent spreading of River sand from the

trucks.

b) Water Requirement:

The proposed Mining activity requires 3.0 KLD of water. This includes water for domestic

purpose, plantation and dust suppression. Water required will be sourced from wells

available in surrounding area and adjacent river. The depth of River sand mining will be

limited to 2 m. Hence there will not be any significant impact on hydrology of the river.

Fluctuation of Water Table:

The River sand mining will be limited to 1.5 to 2.0 m depth which is in accordance with

MoEF stipulations; hence the ground water depletion will not occur due to the proposed

River sand mining.

Hydrology of River:

It is open cast River sand mining only. Shallow pit will be formed due to excavation. The

depth of mining will be limited to 1.5 to2.0 m .Hence there will not be any significant

change in hydrology of the river.

Waste Water:

Sanitary waste water generated will be treated in septic tank followed soak pit outside

the Mining block. Hence there will not be any impact due to the waste on the water

environment.

Anticipated Impacts:

There will not be any water pollution due to the following reasons in this proposed

Mining activity.

As the proposed activity is a process involving manual scooping/ mining of sand from

the River bed for a depth of 1.5 to 2.0 m only.



c) Solid Waste:

The mining does not involve any processes such as overburden removal, drilling, blasting

and beneficiation. The mining will involve extraction of river sand by simple hand tool,

sorting, manual picking and loading into trucks / tractor / trolley for transporting. Hence

there will not be any waste disposal yards proposed.

d) Impact on Vehicular Traffic:

The vehicles using this road are very few. The excavated sand will transported to the

various places for Building construction, road construction places. River sand will be

transported in tarpaulin covered trucks. Number of trucks per day to transport brick will

be 12 to 15 The existing roads can handle this additional vehicular traffic. Hence there

will not be any significant impact on vehicular traffic.

e) Noise Environment:

The Mining/ Desilting of river sand will not have any adverse effect in Noise levels as the

operations are totally manual in nature. No mechanical methods will be used in the sand

excavation. The excavated sand will be transported in tarpaulin covered trucks. Number

of trucks per day to transport brick will be 12 to 15. The existing roads can handle this

additional vehicular traffic. Hence there will not be any significant impact on vehicular

traffic. Hence noise pollution is very minimal.

f) Land Environment

In the proposed Mining activity there will not be much impact on the land environment

due to the following reasons.

1. There is no removal of vegetation such as plants, bushes in the reach area.

2. The proposed Mining/ Desilting of sand block area are situated on the delta /surface of

river bed. Alter extraction / mining, the land is not utilized for any other purposes.



3. No effluent generation as any further processing of mineral is proposed. Hence, no

ground water contamination due to the proposed mining activity.

4. The extraction / mining excavated pit will be allowed for resedimentation in rainy

season.

g) Biological Environment:

As the area is devoid of any vegetation, river sand mining is not going to cause any

damage to any plant species. Hence the anticipated negative impacts if any are only

minor, temporary and easily reversible.

h) Occupational Health Management:

If the workers are continuously exposed for dust it may affect their respiratory systems

depending upon the resistance of the individuals. However to overcome this problem,

all the workers who work in the mining will be provided with special masks to prevent

the same and also provided with PPE.

Project Benefits:

River sand Mining is to help to flow river water and also help in avoiding flood situation .

The Govt, will get revenue in the form of royalty due to sand mining.

This project will lead to indirect employment opportunity. Employment is expected

during silt excavation, sand transportation, in trade and other ancillary services.

Employment in these sectors will be temporary or contractual and involvement of

unskilled labor will be more.

11.0. MINE CLOSURE PLAN & FINANCIAL ASSURANCE

Preparation of mine closure plan at this stage is not possible because of replenishment /

resedimentation of silt during rainy season of every year.



Since it is continous process ,i.e desilting and allow the area for resedimentation every

year eventhough the following activites are proposed to reclaim the mined out area at

the end.

Proposals are made for plantation all along the 3.0m buffer/safty zone by planting local

plants.

All the temporary building / infrastructures will be removed and area will be reclaimed

for plantation purpose.

a) Disaster Management and Risk Assessment.

Since the mining operation is small scale in nature and is in gently sloping ground with

opencast workings. The anticipated mining depth is up to 1.5 to 2.m. The chance for

disaster due to land sliding of bench slopes is not envisaged. However Cell /Mobile

Phones are provided to the Supervisor for easy communication during any emergency.

b) Care and Maintenance during Temporary Discontinuance.

The requisite care and maintenance procedures shall be followed during temporary

discontinuance of the mine. However due to unforeseen situation if mines happens to

be a temporary discontinuance due to strike, lockout & any order passed by the

government, court and etc, lessee takes the care of mines by providing the fencing the

pit deploying the security guards for watch and ward of the mine.

Payment will be made to all the employees as per the statute and providing medical and

other facilities.
