32
Shri S. N. Mishra (Sub-Divisional Officer, Wani) said that there are few problems of people of Wani area related with mining. Due to deep excavation the ground water level of the region is drastically declined and it is necessary to undertake water conservation programme by mines authorities. He added that project proponent should help in implementing various government schemes regarding rural development, water conservation etc. he said that blasting also causes nuisance to the villagers on large scale. Mine authorities should carry out blasting in specific timing and villagers should be informed in advance about these timing to avoid any untoward incident. He appealed project proponent to take all precautionary measures to control pollution from mining and transportation.
Shri P G Thakkar on behalf of the project proponent replied that blasting will be carry out in specific timing as per the DGMS norms and safety precautions will be implemented within blasting zone and allover mine premises. He added that modern controlled technique will be used for blasting. Water sprinklers and water tankers will be provided to control the emission from mining and transportation within mine premises speed breakers will be provided on transportation road to control the speed of the vehicles to avoid the spillage of minerals and subsequent issues.
Shri Shriram Kadu (District Mining Officer, Yavatmal) said that mine authorities should implement all measures for controlling the pollution from mining and transportation. He enquired about the CSR funds provided.
Shri P G Thakkar on behalf of the project proponent replied that initially Rs. 1.5 lakhs will be provided as CSR funds and Rs. 50000 will be provided annually for CSR activities.
Shri Sunanda Reddy (Dharitri NGO, Hyderabad) appealed project proponent to maintain the ecological balance by carrying out tree plantation, avenue plantation and water conservation programs etc. He had that although plantation is mandatory on 33% open land of the project, mine authorities
Chairman Shri Rahul Ranjan Mahiwal requested Shri Reddy to give his written representation which includes all these issues so that it can be forwards to concerned authority for further necessary action.

1 Introduction:
Shree Mohd. Abdul Kadir Mohd.Hanif (M/s Mohammadi Minerals) proposes Dolomite
mining over a Chilai Dolomite mine lease area; the lease has been granted by
Government of Maharashtra to said company. M/s. Mohammadi Minerals had made a
formal presentation to the Environment Appraisal Committee of Ministry of Environment,
Forest, & Climate change, Government of India during the period of July 8 -9, 2014.
Observation of the Environment Appraisal Committee is reproduced below:
"The Committee was of the view that proposed project is located in the area with densely
intersected natural drainages in the catchments of the river Vaidarbha and Laliya and in
view that the information presented on hydrology is inadequate and in order to decide
whether OC mining should be permitted, the Committee recommended that a study be
undertaken by the proponent on the i). Framework of hydro-geological and hydrological
regime in the study area and ii). Preliminary assessments regarding the likely effect of mine
drainage on stream flow characteristics and water quality especially with resp ect to
Vaidarbha river which passes adjacent to the proposed project .
Accordingly, M/s Mohammadi minerals have engaged a Enviro Techno Consultant for
the above assignment. He will submit two reports. Preliminary report will be to obtain
Terms of Reference and the second will contain detailed report as per TOR for inclusion in
the EIA report to seek environmental clearance. The study has commenced. Present report
includes preliminary aspects desired by the Appraisal Committee.
2 Location of the study area:
Dolomite is one of the major mineral deposits occurring in the Indian sub-continent. It has
played a great role in development of civilization and industrialization. The occurrence of
low silica dolomite in the proposed area is proved by way of explorat ion and its
production has important role in the local steel industries and cement industries. Also low
silica dolomite is a raw material used in refractory’s, glass and paint industries. It has a
huge demand as low silica dolomite is limited.
Chilai dolomite deposit is a unique deposit which contains low silica & iron which has a
huge demand in SMS, refractory’s, ferromanganese, steel & Ferro alloy metal
manufacturing. It is having demand in industrial area of Chandrapur, Nagpur, Wardha
49
and nearby industrial area. Therefore mining of a low-silica dolomite is in the interest of
nation and industries as well.
Proposed dolomite mining project is located near village Chilai in Wani tahsil of Yavatmal
district of Maharashtra. The study area lies in between the latitude 19° 49' 39.6" - 19° 50'
09.5" N and longitude 78° 55' 32.6" - 78° 56' 09.4 " E on Survey of India Top sheet No. 56
I/13.(Fig-1). The proposed mining area of Dolomite mine area is about 61.91Ha and the
proposed production will be @ 1.5 Million TPA by opencast mining. (Fig-2). Chilai dolomite
mine is about 25km from Wani town. Nearest railway station is Kayar at distance of 17 km.

3 Physiography and drainage:
Physio-graphically, the study area Slope of mine lease is towards Vaidarbha river
which flows from NW-SE along the lease and is the main drainage of the area.
Highest and lowest contours are 211 and 197 m. General surface slope slope
towards the Vaidarbha River to east. It flows from N-NW to SE. It is at minimum 500 m from
the lease. Western side of lease has a slope towards Laliya nalla. Few seasonal drains
flow into Laliya nalla during monsoon and it meets the Vaidarbha River. Ultimat ely,
Vaidarbha River meets River Penganga further south. (Fig-3).

4 Climate and Rainfall:
The climate of the area is tropical. The rainfall data has been collected from Yavatmal
Taluka Office. The temperature and humidity has been collected from
Yavatmal Meteorological Station. The climate of this district, which is similar to
neighboring districts of north Deccan, is characterized by a hot summer and general
dryness except during the southwest monsoon season. The cold season from December
to February is followed by the hot season from March to May. The period from June to
September is the southwest monsoon season and October and November form the post
monsoon period.
Rainfall: The average rainfall during 10 year period 1995-2004 was 1,036 mm. Only during
four years rainfall had gone below 1,000 mm. The maximum rainfall was 1,379.8 m during
1995 while minimum was 716.4 mm during 2004. Records of rainfall in the dis trict
are available for 11 stations for the period ranging from 10 to 49 years. The normal
annual rainfall in the district is 1012.1 mm. The rainfall generally increases from the
northwest towards the southeast. Ner, near the northwestern border of the district gets
annually 870.3 mm while Panderkawda near the southeast border gets 1145.7 mm. The
rainfall during the southwest monsoon season constitutes about 87% of the annual
rainfall, July being the rainiest month. The variation in the rainfall from year to year is not
large. During the fifty year period, 1941-1990, the highest annual rainfall over the district
amounting to 153% of the normal occurred in 1959. 1972 was the year with the lowest
annual rainfall which was only 64% of the normal. In the same fifty year period rainfall less
than 80% of the normal occurred in 8 years, two of them being consecutive. The annual
rainfall in the district was between 801 and 1300 mm in 37 years out of 50. On an average
there are 52 rainy days (i.e. days with rainfall of 2.5 mm or more) in a year in the district.
This number varies from 47 days at Ner to 58 days at Pandharkawda. The heaviest rainfall
in 24 hours recorded at any station in the district was 339.0 mm at Panharkwda on 14th
September 1959. Average rain fall of 1190mm is recorded across the district of Yavatmal.
Temperature: There are two meteorological observatories in the district, one each
at Yavatmal and Pusad. The description which follows is mainly based on the records
of the observatories in the district. Temperatures rise rapidly after February till May which
is the hottest month of the year. In May the mean daily maximum temperature is about
42.10C and the mean daily minimum temperature is about 27.7oC. The heat in the

summer season is intense and on some days in May and June the maximum
temperatures may rise upto 47oC. The afternoon heat is sometimes relieved by
thundershowers. With the arrival of the southwest monsoon by about the middle of
June, there is an appreciable drop in day temperatures and the weather
becomes pleasant. After the end of September, when the southwest monsoon
withdraws, the day temperatures increase slightly, but the night temperatures
decrease progressively. After October both day and night temperatures decrease
rapidly. December is usually the coldest month with the mean daily maximum
temperature at about 290C and the mean daily minimum temperature at about
13oC. In association with the western disturbances which move across north India cold
waves affect the district and the minimum temperature may occasionally go down up to
about 3-4oC. The highest maximum temperature ever recorded at Yavatmal was
46.6oC on 11th May 1988 and 5th June 1995. The lowest minimum temperature ever
recorded was 3.0oC on 30th January 1980. The highest maximum temperature ever
recorded at Pusad was 49.9oC on 8th April 1990 and the lowest minimum temperature
was 4.2oC on 4th January 1991.
Humidity : Except during the southwest monsoon season when the humidity is
high (70- 80%) the air is generally dry. The summer months are the driest, with the relative
humidity in the afternoons being about 20%.
Wind Velocities and Wind Direction: Winds are generally light to moderate with
some strengthening during the period May to August. In the post-monsoon and cold
seasons the winds generally blow from east or northeast. Micro-meteorological data
recorded for the month of October-December is tabled below.
5 Geology:
The proposed mining area lies in the Gondwana formation. The Gondwanas are well
developed against the Cuddapas. The Cuddapa formations are older than Gondwanas.
Regionally the area is having the formations from basement complex i.e. gneisses,
granites etc. to youngest one is basalt which is of cretaceous age. Archeans i.e.
basement complex (granites, Cuddapas in the form of red shells, highly siliceous to low
silica dolomites & limestones) are represented in this area. Gondwanas having Kamthis,
Barakars & mottur are present; similarly basaltic capping with inter trapean clays are
overlain on Cuddapas and Gondwanas at so many places (Figure -4).
55
The area is well faulted so that at one natural RL we are encountering Cuddapas in the
form of shell, dolomite etc and Kamthis etc against the older formation. Major faults in
the form of rivers like Nirguda, Vaidarbha & Penganga are seen. All these formations are
faulted post deposition so that perennial springs are available at Kayer Wadzari etc
within the buffer zone area. The proposed mining area is also highly disturbed. The
stratigraphical sequence in the area is shown in below Table-1.

Beds Dolomite (low & high silica) Red shell
Basement complex Archeans Granites Granite gneisses
The project Dolomite is an inlier i.e. younger formation is surrounded by older . There is a
possibility of presence of Gondwanas which may be dolomite bearing, are underneath the
basaltic formation which may have to be explored. Dolomite, which is the project area is
having the general strike of NW-SE with a dip of 10 to 150 at places 250 due southwest
direction. In general, the limestone & dolomite are siliceous but at places like Hiwardara &
Mukutban & Hirapur have cement grade limestone & low silica dolomite. Mining at these
places is in progress
6 Hydrology:
Drainage is simple. Dolomite deposits are hard and massive. Permeability is very
low. Hence rain water is likely to be drained in to the river. Surface sources
within10 km radius is the perennial Penganga River and the seasonal Vaidarbha
river. Water from river Vaidarbha is being pumped for agriculture by a few
agriculturists along the river. There is no organized rural water supply within 10
km radius. Most people use hand pump/bore well.
Permission by GSDA to use water @ 50 m3/day during the operational phase of
the project.
Hence, Hydrologically the area is having a simple drainage which having gentle slope and
the rain water will not effect to the lease area as the rain water divides itself into small
segments. The Lallya nalla & Vaidarbha river will be charged with mining water during the
57
mining operations. The area is in between the Vaidarbha river & Lallya nalla, which is a
seasonal one. A very small drainage hardly of 2 Km in length forming a storm nalla during
excess rainfall, if any of existing fields is present, while mining it will be automatically
diverted due to dumps etc. So there is no need of modifications, diversions and channeling
of natural drainages of existing river or nalla. In addition, it is observed that no river or nalla
flows through the lease area.
7 Hydro geology:
The core & buffer zone area are having different geological formation. The buffer zone
area is having hard, massive basalt in Northern portion and highly siliceous dolomite and
Limestone in remaining area of around the actual lease area. The lease area only have
exposed or established sandstone of Kamthis & Barakars. The limestone, dolomite & basalts
are hard, massive formation after a general weathered zone of 1.5 to 2.0 Mts depth. Due
to compactness of these formations, the rain water will move along the existing drainages
with very less deep percolation into soil.
There will not be generation of effluent. Proposed mine will not intercept water table. Only
rain water may accumulate in the pit during monsoon. This water after treatment will be
used for plantation, dust suppression, fire fighting, and other industrial and domestic
applications.
Secondly the natural faulting along the Vaidarbha river and Lallya nalla the natural
drainage will be terminating into these two drainage systems. The lease area falls under
these two main drainages. The lease area will be safe from the drained rain water due to
the termination of the rain water which is expected to recharge the lease area. The
recharge into the lease area due to annual rains will be within the sandstone area i.e. the
lease area only. Hence Hydrogeologically the lease area will be safe due to existing
geological formation in buffer zone around the leasehold area.
8 SURFACE WATER:
Rain water which immediately flows through existing drainage system is the surface
water. Most of the drainage system is not perennial. The Vaidarbha river may be
perennial after good rains in that year, or otherwise it goes dry in summer season. It
indicates the low recuperation into the rock system in buffer zone. Due to the low
58
recuperation in rainy season & due to the absence of the favorable geological
formation, this could have provided the continuous water to the drainage system.
Secondly the chances are also feeble. This is because the geological formations
available nearly after 2.5 to 3 km along north or north-west direction in buffer zone are
hard compact basalt / dolomites. Due to compactness & hardness of these formations
and absence of any deep aquifers, the chances of providing surface water perennially
to the river that means lease area does not arise. It seems that the surface water do not
subscribe or interfere the lease area by in large.
As a part of the survey, the highest contour is 211 m to the N-NW and the lowest contour
is 197m at village Tejapur to the SE of lease near the Penganga river which shows that
general slope is towards south east direction.. Area is drained by the River Penganga,
which flows from west to east. There are several sub-drainages. Main sub-drainage is the
Vaidarbha River, which meets the Penganga. The Vaidarbha river is minimum 500 m to
the east of lease. Another major sub-drainage of concern is the Lallya drain and is to the
south - west of lease. A few seasonal drains flow into these. The lease area which may
recuperate is mainly covered by forests, agricultural field, open scrubs etc. Habitations
are relatively sparse. Slope of area is 0.5-0.6 per cent.
Most widely used is the Rational method viz. Q= C.I.A where Q is runoff in feet 3 /sec, C is
the coefficient of runoff, I is the rainfall intensity in inches per hour and A is drainage area
in hectors and the discharges are worked out as per segments. Coefficient of runoff
varies with land uses soil, slope etc. In the present case slope is less than 1%, soils are
covered by agriculture/forest. Coefficient of runoff is taken as 0.09 since soils are heavy,
maximum rainfall intensity is 25mm per hour. Actual rainfall hours during 90 days monsoon
are 100 and effective area is 11, 618 Hectors. Therefore, runoff will be 685.78 M3/sec i.e. 6,
85, 780 liters/sec. In this area, rain is restricted to June to September i.e. 90 days. Annual
rainfall is 930 mm/year. In filtration is 10% for the formations of this area. Rational method
is used in this report. Maximum flood discharge by rational method will be 685.78m 3/sec.
Velocity in the river for the span of river would be 6.87 m/sec during flood. This has been
calculated for available gradient & average span of the river.
Dewatering of mines during monsoon will be @0.025 cum per second since dewatering
will be about 2000 cum/day. It is very small compared to the total discharge of
59
Vaidarbha river in rainy season. Hence, the runoff will not affect the additional recharge
of the mine during monsoon.
9 GROUNDWATER:
The core and buffer zone area consists mostly of hard rock area. A small portion covers
under Gondwanas mainly sandstone and shale. The hard rocks, limestone, dolomite or
basalt, are compact in nature. So runoff is much more rather than the percolation in
these rocks due to compactness. Rainwater is the main source for ground water. In
general in hard rock area the infiltration factor is approximately 10% and in sandstone it
remains nearly 15%.
The groundwater recharge for the study area has been calculated. The recharg e to
groundwater is calculated by two method, one by infiltration method and second by
water table fluctuation method.
The total area is about 61.91 hectare and the average rainfall as recorded for last 15
years is taken and it comes to 930 mm. Similarly the static water tables of all existing dug-
wells and bore-wells, domestic and irrigation are physically measured. The levels of pre
monsoon and post monsoon period i.e.in May and November of this year is recorded.
The levels are from all villages falling in core and buffer zone. It is also seen that the most
of the dug-wells which are in hard rock go dry in May this year. Hence static water levels
of bore-well of that village are taken as pre monsoon level. It is also noticed that the
perennial irrigation by dug-wells is negligible. Only the ground water irrigation from bore
wells is noticed. The area of such irrigation is also very small. There is no irrigation through
dams, rivers or ponds are noticed in this area. From the data collected the total draft b y
all means & incremental recharge through dug well etc is calculated for to take the
water balance in the buffer zone area. The recharge through this hard rock is very small.
Runoff is also more than recharge. Even though the average recharge of 10 % is take up
for calculation.
In hard rocks that is dolomite & limestone, which is at places beneath the basalt
formation, is having poor aquifer in nature. From the data collected and the
observations in the field, it is found that the open dug well or in bore wells in domestic or
irrigation areas do not behave in the same manner. Most of the dug wells & bore wells
go dry even in the vicinity of village. It is due to the presence of no uniform aquifer
nature. The aquifer formed by bedding plains, cracks and joints are not well connected
60
to each other. From the data collected the aquifer present here have very low specific
capacity, poor permeability and poor Transmissivity.
The ground water characters of sandstone area are bit different from the hard rock area,
as the sandstone in general have the uniform aquifers. But within the dolomite area,
these faults behave like opening for ground water. These faults are seen to be not
connected to each other. Hence the ground water in this aquifer flows from higher
elevation to lower elevation of these faults. The characters of both the aquifer as
calculated from the field data and mentioned in Table-2.
TABLE-2: Aquifer properties in the study area
S. No. Aquifer Transmissivity Specific Yield Permeability ‘T’ ‘S’ ‘K’
1.Hard rock (L.Stone, Dolomite) 509.56 - 0.0048% - 7.66 M/day 1440 M2/day 0.058% 35.02 M/day
2.Sandstone 39.274 - 4.25% - 68.95 M/day
97.442 M2/day 5.91% 122.02 M/day
Actually the area of buffer zone is as considered as the study area. As per Ground Water
Survey and Development Agency, Govt. of Maharashtra, have been calculated
groundwater balance and mentioned in the Table-3. The water balance by both
methods namely total recharge by rainfall infiltration and total recharge by water table
fluctuation have been calculated and compared with obtained stage development.
TABLE-3 : Groundwater Assessment in the study area
Sr. no Area in Ha Net recharge in Total withdrawal
Stage of

The derivation of groundwater balance are based upon the actual figure of rainfall for
last 10 years and fluctuation of water table in pre monsoon & post monsoon static water
tables as recorded physically in the field of the villages in the buffer zone. Actually due to
hard rock terrain there will not any effect in the additional recharge of lease area.
Hence, the area is classified as SAFE as per present data from groundwater
development with reference to Groundwater Estimation Committee (GEC, 2009) Norms.

10 WATER QUALITY:
The quality of groundwater is as much important as its quantity especially when it is used to meet particular
re quirements like drinking, domestic and agriculture. A detailed survey has been conducted in the study
area to collect water samples from established observation well network includes hand pumps (08 No.)
bore wells (02 No.) and dug wells (01 No.). In addition, surface water samples (02 No.) from a poodle in the
River Vaidarbha and from the Penganga river were collected (Table-4) i.e. one is from upstream and other
one is from downstream of the study area (Fig.5).

Methods for the Examination of Water and Wastewater" published by the American Public Health
Association: 20th edition (1998). Water quality analysis (ground water/surface water) has been carried out
for all major ion concentrations and trace elements and mentioned in the Table -5.
Ground water is calcium bicarbonate (CaHCO3) type because of the
concentrations of alkaline earths (Ca & Mg), alkali metals (Na & K), weak acids (CO3
& HCO3) and strong- acid ions (Cl & SO4 & NO3). Surface water quality of Penganga
river is as per requirement of drinking water quality criteria can be a source of water
supply after conventional treatment. Overall, the water quality of the study area is in
normal and the concentration of all parameters is within permissible limits as per BIS
standards.
In present case, it is stated that, the surface water is in the form of seasonal rainfall
accumulated in pits. At the end of ensuing Scheme period, the depth of pits will be
30m, it is expected that water accumulated in pits will be partially percolated in
ground itself. Also
62
Figure-5 : Location of water samples in the study area
63
there would be seepage of water in pit for which dewatering may be required.
Water quality of pumped out ground water, may not change as the rocks of that
nature do not occur in the lease area. However, ground water quality will be
monitored quarterly as per CPCBs’ notification 422(E) and drinking water parameters
will be analyzed as per BIS standards 10500 through accredited environmental
consultant. Surface water from nallah or river or from reservoir is not being used nor
will it be used in future for any mining activities including beneficiation. Therefore,
surface water will be unaffected due to operation of this mine. A stone wall at the
toe of dump will be erected to avoid the wash-off. While winning the Dolomite, no
toxic elements are used or no toxic elements constitute the part of soil and Dolomite,
therefore, no water contamination or pollution takes place. There is no potential of
acid- mine drainage, as rocks of that nature do not exist in lease area.
In addition, CGWB has carried out a detailed study for concentration of fluorides in
groundwater in complete Yavatmal district. The concentration of fluorides varies
from place to place in different rock type vertically & laterally. High contents of
fluorides ranging from 0.91 to 13.41 mg/ltr, have been found only in deeper zone
whereas the shallow zone has not shown the fluoride content above the permissible
limit. Not a single village is recorded from the buffer zone area, hence the buffer
zone if free of fluoride problem.

11 SUMMARY:
Proposed dolomite mining project is located near village Chilai in Wani tahsil of
Yavatmal district of Maharashtra and it lies in between the latitude 19° 49' 39.6" - 19°
50' 09.5" N and longitude 78° 55' 32.6" - 78° 56' 09.4 " E on Survey of India Top sheet No.
56 I/13.
The proposed mining area of Dolomite mine area is 61.91Ha and the proposed
production will be @ 1.5 Million TPA by opencast mining. The normal annual rainfall in
the study area is about 1012.10 mm.
The proposed mining area lies in the Gondwana formation and the Dolomite, which is
the project area, is having the general strike of NW-SE with a dip of 10 to 150 at places
250 due southwest direction.
Hydro logically, the area is having a simple drainage which having gentle slope and
the rain water will not affect to the lease area as the rain water divides itself into small
segments. Proposed mine will not intercept water table and only rain water may
accumulate in the pit during monsoon. This water after treatment will be used for
plantation, dust suppression, fire fighting, and other industrial and domestic
applications.
The lease area will be safe from the drained rain water due to the termination of the
rain water which is expected to recharge the lease area . Hydro-geologically the lease
area will be safe due to existing geological formation in buffer zone around the lease
hold area.
Dewatering of mines during monsoon will be @0.025 cum per second since
dewatering will be about 2000 cum/day. It is very small compared to the total
discharge of Vaidarbha river in rainy season. Hence, the runoff will not affect the
additional recharge of the mine during monsoon.
In hard rocks that is dolomite & limestone, which is at places beneath the basalt
formation, is having poor aquifer in nature. From the data collected and the
66
observations in the field, it is found that the open dug well or in bore wells in domestic
or irrigation areas do not behave in the same manner. Most of the dug wells & bore
wells go dry even in the vicinity of village. It is due to the presence of no uniform
aquifer nature.
The derivation of groundwater balance are based upon the actual figure of rainfall
for last 10 years and fluctuation of water table in pre monsoon & post monsoon static
water tables as recorded physically in the field of the villages in the buffer zone. Due
to hard rock terrain, there will not any effect in the additional recharge of lease area.
Hence, the area is classified as SAFE as per present data from groundwater
development with reference to Groundwater Estimation Committee (GEC, 2009)
Norms.
A detailed survey has been conducted in the study area to collect water samples
from established observation well network includes hand pumps (08 No.) bore wells
(02 No.) and dug wells (01 No.). In addition, surface water samples (02 No.) from
upstream and downstream of the study area i.e. a poodle in the River Vaidarbha
and from the Penganga river were collected. Overall, the water quality of the study
area is in normal and the concentration of all parameters is with in permissible limits as
per BIS standards.
In addition, it is proposed to establish two to three bore wells in and around buffer
zone to regular monitor of groundwater levels and groundwater quality of the leased
area during entire mining operation period as per MOEF / CPCB prescribed norms to
study the local groundwater regime.
