110/P (Old) – 136/P(New) village - Virpur, taluka – Kalyanpur, State – Gujarat
which was sanctioned by Govt. of Gujarat in favour of M/s Bharat Abrasives &
Chemical Industries, initially, for 20 years commencing on 16.10.1979 (date of
execution of mining lease).
Subsequently the mining lease was transferred in the name of M/s B. P. Abrasives

the remaining period and the transfer deed of mining lease was executed on
24.02.1984.
The company negotiated the transfer of the said mining lease in favour of Shri
Nataraj against Govt. of Gujarat for the remaining period ending 15.10.1999 to
cater to its captive requirement.
The date of expiry of ML was 15.10.1999 and applied for renewal.

CHAPTER 3.0
ANTICIPATED ENVIRONMENTAL MEASURES AND MITIGATING
MESAURES
Opencast mining involves extraction of underneath minerals; it’s dumping, and dumping
of waste along with related operations viz. vehicular movement, drilling & blasting etc.
The environmental parameters likely to be affected by this mining project and mitigating
measures are discussed below-
Environmental
Parameters
Landscape and
land use pattern
Impact
Land will be degraded due to
mining and dumping of waste
Air Quality Drilling, Blasting and
increased vehicular movement
due to transportation of
mineral and waste generates
air borne dust.
Noise Operation of various mining
machinery and blasting
generates noise.
Water Quality
Soil Quality
Flora
Fauna
Forest Land
Human
Settlement
and
No discharge of effluents
water from the mine. Working
will no intersect ground water
level.
Opencast mining will entail
the removal of soil.
No endangered species of
flora & fauna exists in ML
area as well as in buffer zone.
MNP exists in buffer zone at
about 2.0 km from ML area.
No adverse impact is
anticipated on MNP as there
is no danger to local ecology
due to mining activities.
Forest land does not exist in
the lease area as well in buffer
zone.
No human settlement in mine
area and no human
displacement will be there. No
Mitigating Measures
Soil will be separately stacked. Waste
will be backfilled after confirmation of
non-availability of mineable mineral.
Soil will be used for plantation
purposes.
Proper maintenance of vehicles, water
spraying on haul roads, use of dust
extractors; scientific blasting pattern will
reduce the air borne dust.
Development of greenbelt within
mining area, proper maintenance of
machinery, personal protective wears.
These measures will keep the noise
within permissible limits.
There is no process plant. Mining will
be done at a shallow depth above
ground water level and there is no run
of water from the mine.
Soil if encountered will be stacked
separately and spread evenly over
worked out areas for plantation.
Plantation within ML area has already
been started and shall be continued in
future all around within the ML area.
This will improve the floral
environment of the surroundings.
Marine National Park exists in the
buffer zone not in lease area so no
impact is anticipated on MNP.
Moreover proper care shall be taken in
guidance of forest department.
No measure required.
No measures required.

Socio economic
profile
adverse impact anticipated.
The mining activity changes
the socio economic profile of
the region.
In the area where cultivation is little
and employment opportunities
presently are very much limited.
Expansion in production will generate
more employment and improve the
socio economic condition of the
people.

CHAPTER 4.0
ENVIRONMENT MONITORING PROGRAMME
4.1 AIR
Air sampling stations will be established in core and buffer zone. Air quality
monitoring shall be carried out every as per norms. Proper records will be maintained
in a bound book and result submitted to designated authorities.
4.2 WATER
Regular monitoring of ground water level and quality shall be carried out at suitable
locations. Water samples will be collected four times in a year i.e. Pre Monsoon
(April-May), Monsoon (Aguest), Post Monsoon (November) and winter (January).
The data collected shall be recorded and maintained in a bound book and result will
be submitted to designated authorities.
4.3 NOISE
Noise level will be recorded periodically at mine site near operating machines during
day and night times and records will be maintained.
4.4 LAND
The excavated area will be properly dressed and soil will spread over worked out
area. There will be no residual voids left behind. Plantation will be done along lease
boundary.
4.5 HEALTH AND SANITATION
Periodical medical checkup of workers will be done and medical facility provided to
the worker. Toilets and urinals will be provided near mine site. Drinking water will be
made available to the workers.
CHAPTER 5.0
ADDITIONAL STUDIES
No additional study is required for this mine except public hearing.
CHAPTER 6.0
PROJECT BENEFITS
The mining will produce useful Bauxite. It generates wealth for the country, provides
employment opportunities to local people, increases their earning capacity and
improves their quality of life.

CHAPTER 7.0
ENVIROMENT MANAGEMENT PLAN
The mining in the area should propose a time bound management plans so that
impacts on different environmental parameters are minimum at every stage of
mining. For this following plans are proposed.
7.1 LAND RECLAMATION
The following reclamation plan will be adopted in this mine.
(1) At end of the life of mine, total excavation area will be over an area of 85.04 ha.
which about 12.96 hectares area shall be backfilled & out of reclaimed and
about 60.65 hectares area shall be converted into water reservoirs. Area not
suitable for converted in accumulation of rainwater (11.43 hectares) shall be
rehabilitated by means of plantation.
(II) Total plantation proposed over an area of 60.65 ha including on worked out area,
fresh area, along lease boundary and road side.
7.2 AIR QUALITY MANAGEMENT
Air quality management will be carried out using wet drilling system, controlled
blasting technique, water spraying for suppression of dust, development of green belt
in the mining lease area etc. whereas necessary dust masks will be provided to
workers exposed to high dust emission zones.
7.3 NOISE CONTROL MEASURES
Noise levels shall be kept within permissible limits by proper maintenance of
machinery, periodical noise monitoring, by developing green belt in and around
mining lease area and providing suitable protective earplugs to the workers.
7.4 MANAGEMENT TO MINIMISE IMPACT OF GROUND VIBRATION
AND FLY ROCK
Drilling and blasting will be carried out as per rules. Safety and optimum efficiency
will be assured by adopting proper design of blasting parameters.
7.5 WATER MANAGEMENT
The impact of mining on ground water is not anticipated because the mining will be
done much above the water table. No liquid effluent will generate, so there will be no
chance of polluting the surface water. No water will be accumulated in the pits
during rainy season.

7.6 SOIL QUALITY
There is soil covering in patches, varying from 1.0 meter, in the area, which will be
stacked separately and will be spread over worked out area and stabilized by
plantation.
7.7 FLORA AND FAUNA
There is no significant vegetal cover and endangered fauna in and around the lease
area will be taken due care according to the norms decided by the Govt.
7.8 SOCIO-ECONOMIC UPLIFTMENT
The main source of occupation in the area is agriculture. As the agriculture is low
yielding and the economical status is not so good, the proposed production
enhancement will have significant impact in improving the socio economic status of
the area.
