EXECUTIVE SUMMARY

Geomatics Engineering Group of Civil Engineering Department at Indian Institute of

Technology (IIT) Roorkee has been contacted by the officials of Uttarakhand Van Vikas

Nigam, Dehradun in May 2018 for the survey of Swarna river section at Selaqui region of

Dehradun. The main aim of the survey work and measurements is to carry out the levelling

operation for getting the elevation of the river bed in pre and post monsoon period of year

2018. Survey work was carried out in Swarna river-section near Selaqui town.

State of the art survey equipments e.g. Electronic Total Station and Geodetic GPS

have been used for carrying out the survey. A number of ground control points have been

established on each site at permanent structures at prominent locations on the banks of river.

These reference control points have been connected using Geodetic GPS in the relative point

positioning mode (DGPS).

The river section has approx. 3800 m length with average slope of 1.6%. The survey

work has been carried out independently from the downstream side of the river and is

progressed towards upstream direction, The survey observations are taken at a grid interval of

50 m in longitudinal direction (along the length of river) and in perpendicular across direction

(along the width of the river). Thus the entire river-section is surveyed at a grid of 50 m by 50

m. After the surveys for the pre-monsoon and post-monsoon periods have been completed the

Longitudinal-sections (along the length of river) and the Cross-sections (along the width of

river) have been prepared using the survey computation software.

Size of mineral classification as per IS 1498; 1970, using grading approach has been

carried out. The sampling has been done at 7 locations by excavation of river bed material for

each 500 m stretch of the river, along the length. Sieve analysis was carried out on these

samples in the IIT Roorkee laboratory. Soil can be termed as well graded or poorly graded

gravels with sard. Average percentage of sand observed was around 25o/o,lt is also observed

that percentage of coarse gravel (between 20 to 80 mm) is significant. Average percentages

of coarse gravel at three depths (0.5 m, 1.5 m,2.5 m) are 54oA, 48Vo and 39o/o respectively'

The different of levels for the same location of the mining lot, in pre and post-

monsoon period has been observed in the range of 0.161 m to 0.713 m. The average rise in

the river bed level in the post and pre monsoon period is 0.353 m. Considering the average

mineable width of present mining lot as 150 m and length of river section as 3800 m, the

average volume of material available in one year cycle of replenishment is 2,04,630 cubic

meters. However, considering the changes in the river morphology and width of river after

the 2013 floods, the volume of material for the proposed mining from this mining lot of 150

m width and 3800 m length will be 8,55,000 cubic meters approximately for excavation upto

1.5 m with respect to the river bed levet.

SURVEY WORK FOR BASELINE DATA ASSESSMENT OF SWARNARIYER SECTION AT SELAQUI IN UTTARAKHAND STATE DURING

2018-19

Preamble:

Geomatics Engineering Group of Civil Engineering Department at Indian Institute of

Technology (IIT) Roorkee has been contacted by the officials of Uttarakhand Van Vikas

Nigam, Dehradun in May 2018 for the survey of Swarna river section at Selaqui region of

Dehradun. The survey work is to be carried out in pre and post monsoon season of year 2018.

After deliberations and field visit to ascertain the scope of work and the ground situation at

the site, Uttarakhand Van Vikas Nigam has awarded the work to IIT Roorkee. The'main aim

of the survey work and measurements is to carry out the levelling operation for getting the

elevation of the river bed in pre and post monsoon period.

Scope of Work:

After discussions with the Uttarakhand Van Vikas Nigam (UVVN) official Sri Indra

Singh Negi, Prabhagiya Longing Prabandhak (Khanan), Dehradun, the scope of work has

been decided as follows-

1. Land Survey work for baseline data assessment of Swarna river section including survey

of elevation for center-line of the river and few cross-sections. Along the river, the

sections will be taken at a spacing of 50 m, in longitudinal direction. Total 20 readings

will be taken for each cross-sections across the river, as per ground conditions. 2-3

permanent Bench marks will be established at appropriate places near the river. The

construction/maintenance work for the B.M. will be carried out by UV\rN. If any Survey

of India reference BM is available within 1-2 km from the study'reach of river, then the

BMs will be established with respect to that, otherwise, these will be established

independently. The land survey work will be repeated one more time in post-monsoon

period at the mutually agreed time, provided the river is dry and has proper working

conditions.

2. Size of mineral classification as per IS 1498: 1970, using grading approach will be carried

out. The sampling will be done for each 500 m stretch of the river, along the length. 2

nos. of labour for excavation of the samples will be provided by UVVN.

3

3. Both the works will be carried out for a 3.7 km long section of Swarna river (area23.75

hectare).

Description of the site:

The survey work has been carried out for the Swarna river section at Selaqui area of

Dehradun. The rivers section is mostly clear from the vegetation and have deposits of river

bed material in the form of boulders, cobbles, gravels etc. Agricultural fields are present for

major stretch of the river section closer to the left and right bank of the river. At few places a

bunch of trees are located on island like formations. More number of trees are located closer

to the left bank of the river. Despite the repeated rains which have occurred this year due to

more than average monsoon season, the river is almost dry when the survey work was carried

out in pre and post monsoon seasons, The river section starts near Tilwari village on the

upstream side with Abdullapur on the left bank. The total length of river section is about than

3.8 km. Atakfarm is located at the downstream side of river section on left bank.

The length of Swarna river section to be surveyed and to be used for rnining purpose,

is located between 30"22'48.22" N latitude, 11"51'36.J6" E, longitude (downstream side) and

30'23'53.13" N latitude,77"53'28.36" E, longitude (upstream side). The river section has

approx" 3800 m length with average slope of 1.60/o.The general layout of the river section at

Selaqui area in Dehradun district has been given in Figure 1.

Figure 1: General layout of Swarna river section at Selaqui area as viewed on Google Earth(the approximate mining arca and river center line are marked on it)

Methodology and Work done:

Several field visits to the concemed river section have been carried out by IITRoorkee team members (few visits with the UWN officials Sri I.S. Negi, Sri Bisht and Sri

S.S. Negi in the months of June to October 2018, for collecting the reconnaissance data, meta

data of the ground locations, location of the Survey of India Bench Mark and then the

surveying work in the pre and post monsoon season. Later the inputs from Sri Yadav, DLM

were also used for preparation ofthe report.

The reconnaissance survey data also helped in deciding the selection of control

stations and the work strategy to be adopted for mapping in order to restrict the errors. State

of the art survey equipments e.g. Electonic Total Station and Geodetic GPS have been used

for carrying out the survey. Before starting the survey work, a number of ground control

points have been established closer to the river section. It was mainly in the form ofperrnanent Bench Marks by construction of concrete pillars at appropriate places near the

river section. The construction/ maintenance work for the B.M. has been carried out by

UWN. Out of these, two concrete pillars were constructed at upstream end of the mining lot,

while the other two concrete pillars were constructed at downstream end of the mining lot.

5

For getting better accuracy of survey measurements, it was taken care that the

concrete pillars are constructed on both banks of the river, i.e. on left hand side as well as

right hand side. These pillars were constructed on the river banks at the safe locations having

very less threat offlooding, thus these can act as reference control points for long duration for

the monitoring of the river section year after year. The pair of pillars on upstream and

downstream side were used for positional and direction reference. The two sets of pillars on

upstream as downstream side would also serve the purpose of closing the level survey and to

evaluate the errors. The ground control points at these pillar locations have been connected

with the Survey of India referenee BM, which is available at PWD Inspection Bungalow at

Sahaspur. Since the Survey of India reference BM is at more than I km distance from the

Swarna river-section, the BMs for the river-section have been established using Geodetic

GPS in the relative point positioning mode (DGPS).

The various control points and TBM established for the Swama river section are

given in table no. 1. These control points are also marked on the ground and these may be

utilized as further controls for the survey work in subsequent years, These will act as

reference as well as reduce the efforts in subsequent surveys for the aurrent river section.

Complete survey measurements were taken by Electronic Total Station. The work was

started from the permanent bench mark locations in the form of concrete pillars, which were

constructed specifically for providing control points of the current survey work. Since there

are very less possible geographic landmarks available at or near the river sections, these

pillars would be very useful, if the reference is required for the survey work to be carried out

in subsequent years for continuous monitoring of the morphological behavior of the river-

sections as well as for river replenishment studies. A temple is present at the left bank of the

river on downstream side at approx. 380 m from the concrete pillar. A temporary bench mark

was marked in the temple premises also, which will help as reference in subsequent surveys'

The survey work has been starled from downstream end of the river section and is

progressed towards upstream direction. Although the concrete pillars being used as reference

control points have been constructed at both the ends of the mining-lot, however the

downstream side is closer to the Selaqui town, thus has the logistics advantage for carrying

out the survey work.

The survey work for the river sections has been carried out for the entire width of the

river from |eft bank to right bank, since the location of mining lot can be more efficiently

demarcated if the ground elevation values of entire width-points are available. The reference

pillars as well as few TBMs have been used as reference for this mining lot. The Total Station

is a modern survey device and a total survey solution, which is a combination of 'theodolite'

for measuring the horizontal and vertical angles; 'level' for measuring the elevation

difference between two or more ground locations; and 'EDM' (Electronie Distance

Measuring Device) for measuring the slope distance by electro-magnetic radiations and

computing the horizontal and vertical distance on that basis.

Total Station survey for a river section has been started from the reference oontrol

point (concrete pillar constructed for this purpose). The two concrete pillars on either side of

the river section are used for setting up the bearing/ orientation. Back-sight has been taken for

the control point and then fore-sights are taken for different locations on the river bed. The

survey observations are taken at a grid interval of 50 m in longitudinal direction (along the

length of river) and at a grid interval of 10 m in perpendicular across direction (along the

width of the river). Thus the entire river-section is surveyed at a grid of l0 m by 50 m. The

ETS survey measurements have been carried out in Prism mode, since it ensures better

reflection of electromagnetic radiations, which are used for taking the observations.

The ETS observations have been taken for planimetric coordinates and height

positions for the various points at the spacing of approximate 50 n-r in the longitudinal and 10

m in across direction of the river-section in prism mode. The width of the river is not much"

therefore the observation stations are at less distance only. The instrument has been kept

approximately in the center of the river and the observations towards the river banks have

been carried out. This has helped to keep all the ETS survey-sightings a1 less clistance" It may

be noted that while the ETS instrument used in the survey work is capable of taking

observations upto 4 km in prism mode. therefore it is ensured that the sighting distance has

been kept less to enhance the observation-accuracy" The observational points for the

prominent features e.g. temple, important buildings, river spur locations are also taken" The

land survey has been carried out in the pre-monsoon period and then has been repeated ir-l

post monsoon period. The pre-monsoon survey has been carried out in the month of June

20 1 8, while post-monsoon survey has been conducted in the rnontl-r of October 20 1 8 "

After the surveys for the pre-monsoon and post-monsoon periods have been

completed the Longitudinal-sections (along the length of river) and the Cross-sections (along

the width of river) have been prepared using the survey computation software. The data has

been exported to the Excel file and the difference of elevation has been obtained by

subtracting pre-monsoon levels from the post-monsoon levels. The survey observations of'

both the periods have been compared and evaluated. The difference of levels for the same

location of the mining lot, in pre and post-monsoon period has been observed in the range of

0.161 m to 0.713 m. The pre and post monsoon elevation of the river bed level as measured

with the Electronic Total Station observations has been given in Table no. 2. These values

will act as the basis of the replenishment study of the river for the concemed mining lot. This

elevation difference at each location will help in further analysis for studying the

replenishment behavior of the river. The longitudinal sections corresponding to the pre and

post monsoon period have been given in Annexure A. The cross-sections for pre and post

monsoon period have been divided in two groups. Cross-sections from Chainage 0 m to

3962.915 m (upstream chainage) have been given in Annexure B. The cross-sections have

been made while moving from downstream to upstream of the river, i.e. left portion of the

cross-section depict the right bank and right portion depict the left bank of river. Cross-

I

sections from Chainage 0 m to -380.10 m (downstream chainage) have been given in

Annexure C. The cross-sections have been made while moving from upstream to downstream

ofthe river, i.e. left portion ofthe cross-section depict the left bank and right portion depict

the right bank ofriver. These extra observations have been taken, since a temple exists on the

left bank of the river after chainage -300 m, which may act as a permanent bench mark or

reference for subsequent surveys in future.

Staking out survey for grid points

The coordinates of the grid points with respect to both the banks of the river have

been determined from the Total Station survey. Since the grid distance for estimating the

river bed level along the lenglh of the river has been taken as 50 m, therefore the grid points

at the separation of 50 m have been determined on both the river banks, The coordinates of

these points have been staked out (located on the ground using survey techniques) using

DGPS in RTK mode to improve the accuracy. After these points have been marked on the

ground along the length of the river on both banks, the UWN officials have used wooderV

stone and paint markers so that these points would be available for future reference. The list

of coordinates (in Easting, Northing) of staked out grid locations is given in table 3.

Volume of replenishment and mineable volume available

The average rise in the river bed level in the post and pre monsoon period is 0'353 m

for one year cycle of 2018-19. Considering the average mineable width of present mining lot

as 150 m and length of river section as 3800 m, the average volume of material available in

one year cycle of replenishment is 2,04,630 cubic meters. However, this value should not be

taken as annual average, since the variation ofriver morphology and its characteristics should

be studied for longer duration, with a minimum of three consecutive years' study" Then only

river bed material (RBM) deposition behavior of that particular stretch of the river can be

ascertained.

Carrying capacity of the river increases after controlled mining, since the cross-

section of the river increases due to mining. Sediment carrying capacity reflects the account

of entrainment and transportation by the flow under the certain boundary condition. It is a

comprehensive index characterizing the sediment carrying capacity of flow under the

conditions of equilibrium of scouring and deposition (Yu, et al,, 2001; Milhous, 2005; Yang,

et a1.,2007; Wang, 2007 and Ni et al., 2014).In order to increase the cross-section of river,

either horizontal or vertical expansion can be exercised. Increase of river cross-section in

horizontal direction is not advisable, since it may induce the breaching of river banks, which

in tum will give rise to threat of flooding for nearby places. Therefore, increase in river cross-

section in vertical direction through controlled mining of the river is a more viable option.

The current deposition of RBM in the river for one year cycle (pre-monsoon to post-

monsoon) is about half a meter. In order to increase the river section, it is proposed that

controlled mining upto the depth of 1.5 m from current river bed level be allowed (may be for

current year only), as it will enhance the carrying capacity of the river and the rate of

deposition of RBM will also increase. The similar studies may be carried out in subsequent

years to ascertain the impact of increase in river cross-section by controlled mining'

Also, it has been observed that mining has not been carried out in the present mining

lot in last year, therefore the river bed level is already quite high, thus it might have reached

the saturation of deposition. Therefore, the rate of deposition of material will increase if the

river bed is lowered by controlled mining. It is in line with the law of sediment transport in

the natural streams. As a consequence of controlled mining in the designated lots of the river,

low elevation channels are created, which have got the tendency to get filled first with

sediment flow in the monsoon time. In the absence of that, the material deposition takes place

along the width of river upto the banks of river and this sometimes creates the situation of

breaching ofthe river banks causing flood havoc in the adjoining areas. The above condition

will induce the deposition of RBM for the entire width of river'

Severe floods in year 2013 have impacted the morphology of major and minor rivers

of Uttarakhand, as it has brought huge amount of RBM and silt deposits to the downstream

side. A study has been carried out using satellite remote sensing to study the morphology of

current river-section in pre and post era of 2013 floods. Satellite images of the same river

section pertaining to pre 2013 (pre-flood) and post flood time have been taken. The pre-

monsoon image of February 2013 has been shown in figure 2. Figure 3 shows the satellite

L4

image of the same area of December 2018. The river bank lines,for both the images have

been digitized and overlaid on the satellite image to get an idea of the width of river in that

year. The river bank lines of both the years (pre 2013 flood and post flood) have been

ovedaid on the satellite image of year 201 8, for better comparison as shown in figure 4. It has

been observed that river width has increased at several locations. The primary reason for the

same may be the excessive RBM brought along with the20l3 flood water and the subsequent

monsoon flows. It is evident that, if suffrcient depth of river cross-section is not available, the

RBM will have the tendency to get deposited towards the river banks, which sometimes may

cause breaching ofriver banks, i.e. increased flood threat for the neighbouring areas.

Figure 2: River bank line (shown in yellow colour) of Swarna river-section at Selaqui inFebruary 2013. Satellite image of February 2013 is shown in background.

By increasing the depth of river through controlled mining, the river flow as well as

the deposition of RBM will be more regularized arrd will stabilize the river morphology.

Hence it is proposed that mining upto a maximum depth of 1.5 m may be allowed for current

year and the situation may be studied for subsequent year (by ground survey ofriver-section

in pre and post monsoon period of year 2019). Therefore, considering the changes in the river

morphology and width of river after the 2013 floods, the volume of material for the proposed

SIZE OF MINERAL CLASSIFICATION

Size of mineral classification has been carried out, using grading approach, as per IS

1498:1970. Forthis soil exploration program has been conducted on the river stretch of3.7

km. The sampling has been done for every 500 m stretch of the river at seven locations, along

the length of river. The sampling was done in the field at the interval of approximately 600 to

700 m. The manual digging and collection of the samples was carried out carefully, owing to

the presence oflarge boulders on the river bed. The pits were excavated up to the depth of2.5

to 3 m. Then samples were collected from the depths at 0.5 m, 1.5 m and 2.5 m. Quantity of

sample collected at each depth was varying from 3 to 10 kg. The similar approach is followed

for collection of samples from all the pits.

Sieve analysis was carried out on these samples in the IIT Roorkee laboratory. Grain

size distribution for 21 samples (seven ground locations and three depths at each location) are

presented in the Annexure 'D' in 21 Charts. Various parameters like Dro, D:0, Dso, Doo, Cu

and C" are obtained from grain size analysis and summarized in table 4. Similarly,

percentages of gravel sand and fines are obtained from sieve analysis. After finding

percentage finer correspondingto 10,30 and600/o (Dro, D:0, Doo) uniformity coefficient and

coefficient of curvature gradation of each sample can be determined. Similarly, average

particle size Dso is also found out for each sample. On an average 74.4% Gravel, 25%o sand

and 0.5Yo fines were present. Mainly size can be classified as either GW or GP. Average

particle size Dso was around 20.7 mm. Depth wise average particle size at three depths are 23,

22.3, 16.7 mm. Average effective size Dro was around 1.1 mm. Depth wise average particle

size at three depths are 1.1, 0.9, 1.3 mm. Soil can be termed as well graded or poorly graded

gravels with sand. Soils with particle size between 4.75-80 mm are classified as gravels. In

which they are further sub-grouped as 4.75-20 mm fine gravel and 20-80 mm as ooarse

gravel. Particles between size 80-200 mm are considered as cobbles (IS 1498-1970). Average

percentage of sand observed was around 25%. ft is also observed that percentage of coarse

gravel (between 20 to 80 mm) is significant. Average percentages of coarse gravel at.three

depths (0.5 m, 1.5 m, 2.5 m) we 54Yo,48Yo and 39% respectively. Only at one particular

location25Yo were observed in the sampling, everywhere else it was coarse gravels.

ENVIRONMENT MANAGEMENT PLAN

1 INTRODUCTION

Environmental Management Plan is a guiding document for environmental impacts associated with

the proposed projects. It is a guiding document for management of good environmental condition

on the site & surrounding of the proposed sand mine. The Environmental Management Plan (EMP)

has been formulated and integrated with the sand mine planning keeping in view overall scientific

development of local habitat and the adverse impact that may be caused due to the sand mining

operation.

A scientific assessment of these impacts those are likely to influence the existing environmental

scenario is needed. This could also facilitate in formulating a suitable environmental management

plan depicting all mitigation measures. It can help in implementing the project in an eco-friendly

manner.

The project activities influencing the following environmental attributes have been studied and

their impacts on the following attributes have been assessed.

• Air Environment

• Water Environment

• Land Environment

• Noise Environment

• Biological Environment

• Socio-Economic Environment

2 Description of the Project

The proposed project is Mining of Sand, Bajri, Boulder (minor mineral) from the bed of Swarna

River of area 23.75 ha at Near Village: Abdullapur & Rampur, Tehsil - Vikasnagar, District –

Dehradun, State- Uttarakhand and the estimated project cost is Rs. 25 Lakhs. It has been proposed

to collect 2,16,000 tonnes per annum.

3 OBJECTIVES

To ensure that sand extraction will be carried out in an eco friendly manner.

To reduce the potential impacts of proposed sand mining extraction operations on the stream

and riparian habitats of streams, river bank stability etc.

To provide employment opportunities to the locals

To restore the ecosystem to the maximum extent possible.

4 ANTICIPATED IMPACTS AND MITIGATION MEASURES

The pollution potential of the proposed project, its possible impacts on the surrounding

environment during pre-operational and operational phases and the necessary management

actions proposed for control and abatement of pollution are furnished hereunder.

4.1 AIR ENVIRONMENT

4.1.1 Anticipated impacts

a) Due to Haul road/ Access Road

Plying of trucks from public road to river sand collection points needs access roads. Majority of

such access roads are the same existing roads/tracks being used by pedestrians/cart owners.

Movement of heavy vehicles sometimes causes problems to cattle post, agriculture land, and human



habitations due to dust, noise and movement of public. These environmental problems are felt

more as the area is rural in nature.

b) Due to Mining process

Air pollution is likely to be caused at various stages of sand mining operations such as excavation,

loading of material. Most of the dust will be generated from loading. This dust becomes air borne

and gets carried away to surrounding areas. The impact on air is mainly localized in nature as the

dust particles are not carried to longer distances and the effect is felt within the core zone of the

project involving active Sand mining operations.

4.1.2 Mitigation Measures

a) Mitigation of Impacts on Access Roads

Movement of the vehicles on the road will be increased; however, unmetalled road in the mining

area will be sprinkled with water at regular intervals. In addition to prevent spillage by trucks over

loading should be controlled along with speed limit (10 tonnes/ truck). Water will be sprinkled on

regular basis to control the dust generation.

b) For Fugitive Dust Emission:

To avoid fugitive dust emissions at the time of excavation, regular sprinkling of water will be

done on regular basis.

Sand is transported to the sites by road through trucks covered by tarpaulin sheets.

To minimize the vehicular pollution from the sand transporting vehicles, the following

conditions are insisted to permit the vehicles of the transporters:

o The vehicles should have pollution control certificate (PUC) issued by appropriate

authorities.

o Regular maintenance of transport vehicles and monitoring of vehicular emission levels at

periodical intervals.

Green belt development along the haul roads, which will act as pollution sink.

4.2 WATER ENVIRONMENT


As the project activity is carried out in the dry part of river bed, none of the project activities will

affect the water environment or riverian habitats. Project activities will not have any adverse effect

on the physical components of the environment and therefore may not have any effect on the

recharge of ground waters or affect the water quality. Monitoring of water quality will be checked

yearly.

4.2.2 Mitigation measures

Mining is avoided during the monsoon season and at the time of floods. This will help in

replenishment of sand in the river bed.

Mining below subterranean water level will be avoided as safe guard against environmental

contamination and over exploitation of resources.

River stream will not be diverted to form in active channels.



Utmost care will be taken to minimize or control leakage vehicles to be used for sand

transportation.

The washing of trucks in the river will be avoided.

The contractor will follow all guidelines and rules for proper and scientific method of mining

during the period of extracting the sand.

4.3 LAND ENVIRONMENT

The type of mining and the characteristics of the particular mineral deposit both affect the degree

to which mining disturbs the landscape. Sand Mining and allied activities will be done in the fluvial

plain formed by river meandering. Mining of sand may cause a few environmental degradations.


Damage of river bank due to access ramps to river bed, may cause soil erosion.

Destruction of river bank hinterland and ecological due to extraction of sand by probability of

damage to the flood control bunds (built along the river side) due to heavy movements of

vehicles over the bund to approach the mine are and further during transportation for sand

from the mine area.

Disposal of packing material, carried by the workers, would not be allowed. This packing

material would include used sachet/gutka/pan masala pouches.

Movement of heavy vehicles sometimes cause problems to agricultural land, human habitations,

borehole users due to dust, noise and it also causes traffic hazards.

Surface degradation due to road network.


Safety distance of 3m or 1/10th of the width of the river which ever will be more will be left

from both the bank of the river. (As guided by, MOEFCC guidelines on “Sustainable sand mining

guidelines” & Geological Survey of India).

No foreign material like polythene bag, jute bag and useless articles should be allowed to

remain/spill in river bed and catchment area, or no pits/pockets will be allowed to be filled

with such material.

Minimum number of access roads to river bed for which cutting of river banks will be avoided

and ramps are to be maintained.

Care will be taken to ensure that ponding is not formed in the river bed.

Mining will not exceeds beyond the allowed extraction capacity.

Green belt will be developed along the haul road and the bank of rivers of mine premises and

near the sand mining site. While selecting the plant species, preference will be given for

planting native species of the area.

4.4 NOISE ENVIRONMENT


Noise environment in this project will be affected only by the equipment at the site and vehicular

transportation. Since, slight increase in noise levels can be expected.




• Minimum use of Horns at the village area.

• Timely maintenance of vehicles and their silencers to minimize vibration and Sound.

• Phasing out of old and worn out trucks.

• Provision of green belts along the road networks.

• Care will be taken to produce minimum sound during sand loading.

• Use of Backhoe and ear plugs may be provided to protect the labors working at the site.

4.5 BIOLOGICAL ENVIRONMENT


a) Aquatic environment

Proposed mining will not have any possibility of disturbance of aquatic life as it is a dry bed.

b) Flora and Fauna

The mining activity will have insignificant affect on the existing flora and fauna. The project area is

surrounded with agricultural land. It was found that the sand mining activity will not have any

significant impact on the biological environment of the region.


• Improvement in river bank stability.

• Large woody debris in the riparian zone will be left undisturbed or replaced when moved and

not be burnt.

• Vegetative debris will not be stored within the mine lease area.

• Operation and storage of heavy vehicles within riparian habitat will be restricted.

• Covering of loaded vehicles to reduce dust emission, which may harm surrounding agricultural

crops and other plant species.

• Conservation of biological diversity of plants, birds and animals.

• Greenbelt Development and Bio-Diversity Preservation

o Plantation activities will be carried out at the bank of the river and along the haul roads.

o This activity will help for maintaining ecology and environment of the area.

4.6 GREENBELT DEVELOPMENT

The implementation for development of green belt will be of paramount importance as it will

not only add up as an aesthetic feature, but also act as a pollution sink.

The species to be grown in the area should be dust tolerant and fast growing species so that

permanent green belt is created.

To stabilize the river bank erosion the plantation of native species of that area along the river

bank.

Apart from the green belt and aesthetic plantation for elimination fugitive of emission and noise

control, all other plantation efforts shall be decided and executed with the assistance and co-

operation of the local community.

4.7 IMPLEMENTATION OF EMP

Environmental Management Plan serves no purpose if it is not implemented with true spirit. Some

loopholes in the EMP can also be detected afterwards when it is implanted and monitored. Thus, an

implementation and monitoring programmed has to be prepared.

Implementation of proposed control measures and monitoring programmed has an implication on

the surrounding area as well as for the region. Therefore, sand mining management should be

strengthen the existing control measures as elaborated earlier in this report and monitor the

efficacy of the control measures implemented within the sand mining area relating to the following

specific areas:

Coordinate with environment monitoring laboratory for collecting and analyzing air, water soil

& noise quality of the area.

Implementing the control and protective measures.

Co-coordinating the environment related activities within the project as well as with outside

agencies.

Separate Budget has been allocated for the EMP.

Collecting statistics of health of workers and population of surrounding villages.

Monitoring the progress of implementation of environmental management program.

Greenbelt development along the access road at sand mining site.

This project operation will provide livelihood to the poorest section of the society. Approximately

300 people shall work at mine site.

5.1 Anticipated impacts and evaluation

The project activities shall not have any adverse impacts on any of the common property resources

of the village communities, as the sand mine lease area is not being used for any purpose by any

section of the society in this region. There is no R & R involvement in this project. There is no land

acquisition in this project.

The results of the field survey conducted to understand the knowledge and perception of the people

living around the project area gives a clear idea about the need for the project.

A major portion of the houses in the study area are semi- pucca type structures. The water source

to these areas is from the municipal connection and private bore wells and wells. The awareness

level regarding the proposed mining activity is very high.

The proposed mining activity is expected to provide stimulus to socio-economic activities in the

region and thereby accelerate further development processes.

ANNEXURE-IV- Indicating mining will be restricted to 1.5m only.

CHAPTER - 4MINING

Mining (Past):

Applied area for mining is 23.75 ha. The present topography shows some

depositional and erosional or mining activity during past years. Infect mining pits if any,

are replenished every year during the rainy season. The lease area has gentle slope towards

SW. Highest point is at RL 603.5 m in the northeast corner of the area where as lowest

point RL 545m is in the southwest corner of the area.

Proposed Method of Mining:The project does not involve any processes such as drilling, blasting and

beneficiation. The mining process involves collection of material by simple hand tool such

as shovel, pans and sieves. This is followed by sorting and manual picking, stacking and

loading into trucks/tractor-trolley for transporting. The pits from where the material ispicked are not deeper than 1.5m as allowed in mining area and shall follow the normal

channel direction of the river. These get replenished during monsoon. The only waste is

silt/clay which is recycled back to the pits.

Mining will be carried out only during the day time. The factors such as

topography, bed gradient, soils, rainfall etc will be taken into consideration for the same.

The material is transported through the high velocity flow and is deposited in downstream

portion where the bed slope is mild.

Applied area is a part of a river bed and mining will be done manually in open cast

method in quite a systematic manner by forming benches of 1.5m high. However, there

may be variation in the width which the lessee will keep on mending. About 216,000

Tonnes mineral will be exploited per year. From first year to fifth year total 1080,000

Tonnes mineral will be produced. The proposed area is within river bed and mined out area

will be replenished gradually during succeeding rainy season. The sandy soil to be

scrapped manually with the help of pickaxe, spade & crowbar and will be stacked

separately in dump yard located near the working pit. About l0% of the total production is

considered as a waste material and will be used for reclaiming the bank slope. Backfilling

will be done simultaneously in each year.

Prior to any actual mining being done at the site, itoverburden from the top of the RBM. Overburden is sandy soil

composed of silty sand. Sandy soil will be kept separate and used

amenable to excavation. Excavation is typically performed by man ffidils. Hand

operated tools like spade; tasla etc will be used to collect the sand. The avated material

may be directly loaded into trucks, dumpers, tippers and tractors trolleys and send to the

destination wherever it is required for construction and other purposes.

Transportation of sand from the mine is a process to deliver mined out material to

the location where it is going to be collected. Mined out sand will manually be loaded into

truck and transported to its destination where it will ultimately be used. Sufficient space

will be left for loading of trucks. Excavation of river bed minerals will commence from the

top surface of the area and commence towards down removing the minerals manually in

1.5m slices. Ultimate depth of a bench will be 1.5m. Mining will be restricted upto a

maximum depth of 1.5m only. The entire area does not require excavating at once. Per year

about 216,000 tonnes production of river RBM (sand bajri & boulder) have been proposed

to meet the market requirement.

The mineral extraction will be done for a peflod of 270 days in a year. During this

period the areas of mining quary will be free from submergence. During mining operation

the river flow will be away to enable dry pit mining. In the lease area the river flow being

reduced and sediment load get deposited. During flood season, the area gets replenished

with sediments and source of erosion at this location is comparatively less.

The guidelines of the Ministry of Environment & Forests and Directorate ofGeology and Mining will be followed; the most important is as under:

. Dry pit mining will be followed which means mining an all times will be above the

flowing river water level. Mining activity will be immediately stopped when water

comes in the mining pits.. RBM (sand bajri & boulder) will be collected in slices upto a depth of 1.5 m or river

water levels whichever less than prescribed.

. Stream will not be diverted to form inactive channel.

. Mining at the concave side of the river channel will be avoided to prevent bank erosion.

. Mining will be restricted minimum 25Yo fromriver bank to minimize effect of river bank

erosion and to avoid consequent channel migration. Plarftation will be done on such area

to isolate mining operation form the rest of the area.

. Area of mining lease will be demarcated prior to mining and Pillars will be erected on

ground.. No mining operations shall be carried out in proximity of any bridge and or embankment.

Working will be during day-time only; i.e. sunrise to sunset only;

. No constructions will be done at site except for construction of initial temporary shelter

house.

. No water intake from river will be done. Water will be

sources.

supplied

. No machineries will be used.

. Mining will be completely stopped during monsoon season.

Proposed Rate of Production and Life of Mine:

Depending upon the market about 216,000 tonnes per

to be swiped out from the mining area. Each bench will be of 1.5m

sub benches. Tonnage factor of 1.8 has been considered, This material will be expected to

be replenished during the next rainy season.
