final TOR and no other additional TOR received.
1.5 PROCESS FOR OBTAINING ENVIRONMENTAL CLEARANCE
As per the EIA Notification of 14th September 2006 and subsequent amendments, all ‘Category
B’ projects require prior clearance by the State Expert Appraisal Committee. The environmental
clearance process for such projects comprises of a maximum of four stages. The four stages in
sequential order are as given below.
Stage 1- Screening:
It refers to the definite assignment of environmental category to projects or activities where the
same is not completely specified. In case of category B projects scrutiny of application at the
State level to categorize project in “B1” and “B2” is done. The “B2” projects do not require EIA
reports. The proposed project comes under category “B1” Category.
Stage 2- Scoping:
It refers to the process where SEAC determines detailed and comprehensive Terms of Reference
(ToR) for the EIA report and can also include site visits by the committee if required.
Stage 3- Public Consultation:

The bauxite deposit of Kalayanpur Taluka, Jamnagar District,Gujarat is associated with a narrow belt
of laterite extending from Mota Asota Gulf of Kutuch in North to Gandhvi village near Arabian sea
coast on South.
The laterites belt is about 7km. wide between Kenedy & Habardi village and is less than 1km. wide
near Ran, Mewasa & Lamba village. On the west of this belt the laterites overlain by the younger
tertiary rock and to the East they are underlain by the deccan traps.
The laterite is distributed almost as a continuous zone between Gajbeds & underlying Deccan traps.
The Gajbeds which overlie laterite bauxite succession in belt and are mostly sub horizontal in the
deposition. They comprise of yellow colored argillaceous fragmentary limestone.

2.5 QUALITY OF RESERVES
2.5.1 Method of estimation of reserve
The total mineral resources and reserves have been calculated by cross sectional area &
influence width method. In this method the cross sectional area of section line is multiplied by the
influence of the section line to give the volume. This in turn has been multiplied by the bulk density
(2.5 t/m3) to find out the tonnage. The mineral reserve thereafter has been calculated by depleting
remaining resources from total mineral resources.

Fig. 2.4 Conceptual Plan
Backfilling of Voids & Reclamation
Backfilling of Voids
It is not possible to backfill the mined out land up to original ground level. As volume of void
is much more than material available for backfilling. Therefore up to life of the mine the
mined out area will be used as water reservoir as shown in conceptual plan.
Reclamation
The mined out area will be used as water reservoir. The plantation will be on statutory
barrier.
Afforestation:-
It is proposed to undertake plantation program in the lease area. Plantation work will be
carried out along statutory barrier so that a green belt can be developed. About 550 plants of
local species will be planted.
Post Mining land use:-
The basic requirement of local community is storage of rain water therefore the part of the
area will used as water reservoir which will act to replenish the ground water with fresh rain
water which over a period of time will reduce the salinity and farmer will utilize reservoir
water for agricultural purposes.
2.6.2 Life of mine
The expected life of mine is approximately 6 years on the basis of present level of exploration.
2.6.3 Waste Management
The overburden generated during mining scheme period will be Nil only soil will be generated.
Besides the 10 % of ROM as mineralized waste which contains high silica & low alumina. The waste
does not find any use & can be disposed as waste. The topsoil generated during the scheme pried will
be backfilled. The waste generated during scheme period is will be as under:-

reservoir. The stack of dump is shown in year wise development plan plate no. 6.
2.6.4 Reclamation and Rehabilitation of mined out area
i) During Proposal Period – It is proposed to undertaken programme in the lease area.
Plantation work will be carried out along statutory barrier and on backfilled area. Green
belt will be developed around the statutory barrier and around the water reservoirs, also
plantation of the backfilled area is taken up.
ii) At Conceptual Stage–Reclamation will be carried out by simultaneous backfilling
during conceptual stage. About 33% of total area will be rehabilitation by afforestation
of native species. Rehabilitation of mined out land by making water reservoir will be
by developing for Pisciculture, irrigation use and picnic spot etc. Mine road will be
developed in approx. 0.0120 ha.

Drilling and Blasting is proposed in mining plan but drilling and blasting is not adopted hence, whilerequired PP will use breaker and hammer machine instead of drilling and blasting. To avoid pollutiondue to heavy machinery due care will be taken as per the norms.2.6.6 Use of Mineral
The bauxite produced in mining are of two types – high grade & low grade. High grade Bauxite willbe used in captive plant situated at Bhatia. The low grade bauxite will be used in the manufacture ofcement and which is exported to Middle East countries.2.7 GENERAL FEATURES2.7.1 Surface drainage pattern
There is no river or Nalla or well exist in the lease area. A seasonal nalla is passing northern side of
the lease area. There is no fix drainage pattern; rainfall in the area is scanty. During rains, water
flows from higher elevation to lower elevation in all direction. Part of rain water is collected in
working pits, which are soon dried up as rains are not regular. There is no natural drainage pattern
within the lease area.

3.1 Preamble
Baseline environmental status in and around proposed mining lease area depicts the existing
environmental conditions of air, noise, water, soil, biological and socio-economic environment.
The proposed project as a center, a radial distance of 10 km is considered as study area for
baseline data collection and environmental monitoring. The data was collected for various
environmental attributes so as to compute the impacts that are likely to arise due to proposed
development activity by Cognizance Research India Pvt. Ltd. recognized by MoEF as per
Environment (Protection) Act, 1986.
The main aim of the impact assessment study depends mainly on two factors. One is the
estimation of impact from proposed project on the environment and second one is the assessment
of the environmental condition. Both are key factors to arrive at the post project scenario. The
estimated impact due to the proposal mine lease area can be superimposed over the existing
conditions to arrive at the post project scenario. The scope of the baseline studies includes
detailed characterization of following environmental components, which are most likely to be
influenced by the setting up of a mine lease area.
Metrological conditions
Ambient Air Quality
Noise levels
Water Quality (Surface + Ground water)
Soil Quality
Socio economic status
3.2 Study Area
The proposed project as a center, a radial distance of 10 km is considered as study area for
baseline data collection and environmental monitoring.
3.3 Study Period

3.4. Meteorological Conditions
Meteorology is the key to understand the air quality. The essential relationship between
meteorology and atmospheric dispersion involves the wind in the broadest sense. Wind
fluctuations over a very wide range of time, accomplish dispersion and strongly influence other
processes associated with them.
A meteorological station was set up at the proposed plant premises. Meteorological data was
generated during the winter season monitoring period.
The following parameters were recorded at hourly intervals continuously during
monitoring period:
Wind speed
Wind Direction
Air Temperature
Rainfall was recorded on daily basis.

a) Suspended Particulate Matter (PM10)
Suspended particulate matter in general terms is the particulate matter in suspension in ambient
air. It includes dust, smoke etc. In general some of the important sources of suspended particulate
matter are mines. The following sources of suspended particulate matter in the study area are
identified:
Emission due to vehicular movement
Dust generation from ground or other mining operations
The minimum and maximum level of PM10 recorded within the study area was in the range of
57.8 µg/m3 to 89.7 µg/m3 with the 98th percentile ranging between 68.92 µg/m3 to 89.52 µg/m3.

Chapter-3Description of Environment
CRIPL III- 62
b) Suspended Particulate Matter (PM2.5)
Suspended particulate matter in general terms is the particulate matter in suspension in ambient
air. PM 2.5 refers to particles with a diameter of less than 2.5 microns. These are usually called
fine particles and contain secondary aerosols, combustion particles and re-condensed organic
metallic vapour, and acid components. Fine particles can reach all the way down to the alveoli in
the lungs.
The minimum and maximum level of PM2.5 recorded within the study area was in the range of
31.1 µg/m3 to 56.7 µg/m3 with the 98th percentile ranging between 36.39 µg/m3 to 56.58 µg/m3.
The 24 hourly average values of PM2.5 were compared with the National Ambient Air Quality
Standards (NAAQS) and found that all sampling stations recorded in the study area are within
the applicable limits i.e., 60 µg/m3 for PM2.5 in rural areas.
c) Sulfur Dioxide (SOX)
Sulfur dioxide gas is an inorganic gaseous pollutant. Sulfur dioxide emissions are expected to be
emitted wherever combustion of any fuel containing sulfur takes place. The sulfur in the fuel will
combine with oxygen to form sulfur dioxide. The following sources of sulfur dioxide in the study
area are identified:
Emissions from domestic/consumption of fuel (coal, diesel, etc)
Emissions from DG sets used residents.
Sulfur dioxide in atmosphere is significant because of its toxicity; sulfur dioxide is capable of
producing illness and lung injury. Further it can combine with water in the air to form toxic acid
aerosols that can corrode metal surfaces, fabrics and the leaves of plants. Sulfur dioxide is an
irritant to the eyes and respiratory system. Excessive exposure to sulfur dioxide causes bronchial
asthma and other breathing related diseases as it affects the lungs.
The minimum and maximum level of SOX recorded within the study area was in the range of 4.7
µg/m3 to 13.3 µg/m3 with the 98th percentile ranging between 7.74 µg/m3 to 13.21 µg/m3.
The 24 hourly average values of SO2 were compared with the National Ambient Air Quality
Standards (NAAQS) and it was found that all sampling stations recorded values are below the
applicable limits 80 µg/m3 for rural areas.

CRIPL III- 63
d) Oxides of Nitrogen (NOX)
The important sources of oxides of Nitrogen are from utilities and auto exhaust due to vehicular
movement in mine lease area. The following sources of oxides of nitrogen in the study area are
identified.
Emissions from field burning of coal.
Emissions from vehicular movements in the study area.
Oxides of Nitrogen in the presence of sunlight will undergo reactions with a number of organic
compounds to produce all the effects associated with photochemical smog. NOX has inherent
ability to produce deleterious effects by themselves like toxicity. It causes asphyxiation when its
concentration is great enough to reduce the normal oxygen supply from the air.
The minimum and maximum level of NOx recorded within the study area was in the range of
6.3µg/m3 to 22.9 µg/m3 with the 98th percentile ranging between 13.75 µg/m3 to 22.17 µg/m3.
The 24 hourly average values of NO2 were compared with the National Ambient Air Quality
Standards (NAAQS) and it was found that all sampling stations recorded values are below the
applicable limits 80 µg/m3 for rural areas.
e) Carbon monoxide
Carbon monoxide (CO; CAS 630-08-0)) is a colorless, odorless, tasteless gas produced by the
incomplete combustion of carbon-containing material such as coal, wood, paper, gasoline, and
diesel fuel. Known to miners as white damp or the silent killer, CO constitutes a serious health
hazard and exposure to it may even lead to death. Ambient levels of CO in mine atmospheres
may vary depending on the characteristics of the coal. Elevated levels of CO are commonly
found adjacent to gob areas and in bleeder entries and must be carefully monitored.
The minimum and maximum level of CO recorded within the study area was in the range of was
0.17 µg/m3 to 0.96 µg/m3.

3.6 NOISE ENVIRONMENT
Noise is one of the most undesirable and unwanted by-products of our modern life style. It may
not seem as insidious or harmful as air and water pollutants but it affects human health and well-
being and can contribute to deterioration of human well-being in general and can cause
neurological disturbances and physiological damage to the hearing mechanism in particular. It is
therefore, necessary to measure both the quality as well as the quantity of noise in and around the
proposed site.
3.6.1 Source of Noise
The main sources of noise in the study area are domestic activities, industrial activities and
vehicular traffic. The main occupation of the villagers in the study area is agriculture and
business.
3.6.2 Noise level in the Study Area
The baseline noise levels have been monitored at 10 locations within the study zone, using a
sound level meter and noise level measurement locations were identified for assessment of
existing noise level status, keeping in view the land use pattern, industrial area, Silence Zone,
residential areas in villages etc., if available within 10 km radius of the study area. The day levels
have been monitored during 6.00 AM to 10.00 PM and night noise levels, during 10.00 PM to
6.00 AM. The noise monitoring stations are shown in Figure 3.3 and represented in Table 3.8.
The results are presented in Table 3.9.

3.7 WATER ENVIRONMENT
3.7.1 Water Quality
Water quality assessment is one of the essential components of EIA study. Such assessment
helps in evaluating the existing health of water body and suggesting appropriate mitigation
measures to minimize the potential impact from development projects. Water quality of ground
water has been studied in order to assess proposed water-uses in construction, drinking, cooling
and horticulture purpose.

The water quality at the site and other locations within the 10 km impact zone was monitored
during May. The water sampling locations marked within the study and the result of the
monitoring and analysis is presented in the Figure 3.4 showing Water Quality Monitoring
Locations marked within the Study Area.
Sampling Frequency and Sampling Techniques
Parameters for analysis of water quality were selected based on the utility of the particular source
of water as per MoEF guidance. Hence quality of ground water was compared with IS: 10500:
1991 (Reaffirmed 1993 With Amendment NO -3 JULY 2010) for drinking purposes.
As per the standard practice, one sample from each station was taken each month in the study
Period. Sampling was done by standard sampling technique as per the Standard Methods.
Necessary precautions were taken for preservation of samples.

3.7.2 Result & Conclusion:
The pH limit fixed for drinking water samples as per IS-10500 Standards is 6.5 to 8.5 beyond
this range the water will affect the mucus membrane or water supply system. During the
study period, the pH was varying for ground waters from 7.11 to 7.51. The pH values for all
the samples collected in the study area during study period were found to be within the
limits.
The desirable limit for total dissolved solids as per IS-10500 Standards is 500 mg/l where as
the permissible limits in absence of alternate source is 2000mg/l, beyond this palatability
decreases and may cause gastro intestinal irritation. In ground water samples collected from

the study area, the total dissolved solids are varying from 490.6 mg/l to 518.2 mg/l. the TDS
of the samples were above the desirable limit but within the permissible limit of 2000 mg/l.
The desirable limit for chlorides is 250 as per IS-10500 Standards where as permissible limit
of the same is 1000 mg/l beyond this limit taste, corrosion and palatability are affected. The
chloride level in the ground water samples collected in the study area were ranging from 56.
3 mg/l to a maximum of 63.3 mg/l.
The desirable limit as per IS-10500 Standards for hardness is 200 mg/l where as the
permissible limit for the same is 600 mg/l beyond this limit encrustation in water supply
structure and adverse effects on domestic use will be observed. In the ground water samples
collected from the study area, the hardness is varying from 299.7 mg/l to 306 mg/l.
Fluoride is the other important parameter, which has the desirable limit of 1mg/l and
permissible limit of 1.5 mg/l. however the optimum content of fluoride in the drinking water
is 0.6 to 1.5 mg/l. if the fluoride content is less than 0.06 mg/l it causes dental carries, above
1.5 mg/l causes flurosis. In the ground water samples of study area the fluoride value were in
the range of 0.06 mg/l to 0.07 mg/l.
Overall all the samples collected from the study area were found to be fit for consumption, Most
of ground water samples are well within the permissible limits. Most of the heavy metals in all
samples are below detectable limits.

agricultural land.
3.10 Socio-Economic Environment
Introduction
In this section of the EIA report an attempt has been made to assess the socio-economic Impact
of the Mining Project on Bauxite located at Mewasa village, Kalayanpur Taluka, district
Devbhumi Dwarka, Gujarat. The total lease area is 1.0 Hectare.
Socio-Economic Impact Assessment (SEIA) refers to systematic analysis of various social and
economic characteristics of human being living in a given geographical area. The geographical
area is often called Study Area or Impact from happening area. It is carried out simultaneously
with Environment Impact Assessment (EIA). The prime objective of SEIA is to identify and
evaluate potential socio-economic and cultural impacts of a proposed development project on the
lives and conditions of people, their families and their communities. If the potential impacts are
significant and adverse, SEIA assist the developers and other stakeholders to reduce, remove or
prevent these impacts.
SEIA is multidisciplinary, using theories and methods from Sociology, Economics, History,
Psychology, Geography and Anthropology. It is pre-requisite before the project is put into
implementation. The study area consists of the core area where the proposed project is expected
to come up and a buffer area encircling the project area with a radius of prescribed kilometers
from the periphery of the core area. For every new project socio-economic impact assessment is
mandatory. It is also mandatory for existing projects in case of expansion, modernization and

change in product mix. The Socio-economic impact assessment focuses the effect of the project
on social and economic well-being of the community.
Under SEIA it is examined how a proposed development project will change the lives of current
and future residents of a community. The outcome of the study relies on both quantitative and
qualitative measure of impacts. The impacts are evaluated in terms of changes in community
demographics, housing, employment, wage income, consumption pattern, market effects, public
services, retail business, quality of life and artistic qualities of the community. Qualitative
assessment of community perceptions about development is an important measure of
development impacts, without which no assessment is complete. Hence, due importance is given
on qualitative assessment of community perceptions. Further, assessing proposed developments
in socio-economic context help the community leaders and local people identify potential social
equity issues, evaluate the adequacy of social services and determine whether the project has
adverse effects on overall social well-being or not.
Scope of the study
The Scope of socio-economic impact assessment of Bauxite mining project located at Mewasa is
as follows:
a) To collect baseline data of the study area
b) To comprehend socio-economic status of the people living in the study area.
c) To assess probable impact of the project on social and economic aspects in the study area.
d) To measure the impact of the project on Quality of life of the people living in the study
area.
e) To ensure sustainability of positive impact.

Concept & Definition of Terms used in the report
Study Area: The study area, also known as impact area has been defined as the sum total of core
area and buffer area with a radius of 10 Kilometers from the periphery of the project site. The study
area includes all the land marks both natural and manmade, falling therein.
QoL: The Quality of Life (QoL) refers to degree to which a person enjoys the important
possibilities of his/her life. The ‘Possibilities’ result from the opportunities and limitations, each
person has in his/her life and reflect the interaction of personal and environmental factors.

Enjoyment has two components: the experience of satisfaction and the possession or achievement
of some characteristic.
Household: A group of persons who normally live together and take their meals from a common
kitchen are called a household. Persons living in a household may be related or unrelated or a mix
of both. However, if a group of related or unrelated persons live in a house but do not take their
meals from the common kitchen, then they are not part of a common household. Each such person
is treated as a separate household. There may be one member households, two member households
or multi-member households.
Sex Ratio: Sex ratio is the ratio of females to males in a given population. It is expressed as
'number of females per 1000 males'.
Literates: All persons aged 7 years and above who can both read and write with understanding in
any language are taken as literate. It is not necessary for a person to have received any formal
education or passed any minimum educational standard for being treated as literate. People who are
blind but can read in Braille are also treated as literates.
Literacy Rate: Literacy rate of population is defined as the percentage of literates to the total
population aged 7 years and above.
Labour Force: The labour force is the number of people employed and unemployed in a
geographical entity. The size of the labour force is the sum total of persons employed and
unemployed. An unemployed person is defined as a person not employed but actively seeking
work. Normally, the labour force of a country consists of everyone of working age (commencing
from 16 years) and below retirement (65 years) that are participating workers, that is people
actively employed or seeking employment. People not counted under labour force are students,
retired persons, and stay-at home people, people in prisons, permanently disabled persons and
discouraged workers.
Work: Work is defined as participation in any economically productive activity with or without
compensation, wages or profit. Such participation may be physical and/or mental in nature. Work

involves not only actual work but also includes effective supervision and direction of work. The
work may be part time or full time or unpaid work in a farm, family enterprise or in any other
economic activity.
Worker: All persons engaged in 'work' are defined as workers. Persons who are engaged in
cultivation of land or milk production even solely for domestic consumption are also treated as
workers.
Main Workers: Those workers who had worked for the major part of the reference period (i.e. 6
months or more in the case of a year) are termed as Main Workers.
Marginal Workers: Those workers who did not work for the major part of the reference period
(i.e. less than 6 months) are termed as Marginal Workers.
Work participation rate: The work participation rate is the ratio between the labour force and the
overall size of their cohort (national population of the same age range). In the present study the
work participation rate is defined as the percentage of total workers (main and marginal) to total
population.
Birth Rate: The ratio of total live births to total population in a specified community or area over a
specified period of time. The birthrate is often expressed as the number of live births per 1,000 of
the population per year also called natality.
Death Rate: The ratio of total deaths to total population in a specified community or area over a
specified period of time. The death rate is often expressed as the number of deaths per 1,000 of the
population per year. It is also called fatality rate or mortality rate.
Maternal Mortality Rate: The maternal mortality rate, the number of maternal deaths per 1,000
women of reproductive age in the population (generally defined as 15-44 years of age).
Infant Mortality Rate: The infant mortality rate, the number of deaths of children less than 1 year
old per 1000 live births.

Demographic particulars of the study area
The population Census 2011 was not held in Devbhumi Dwarka district due to severe earth quake
in 2001. The population data for the Devbhumi Dwarka district was therefore estimated by the
Census authority. The population Census 2011 was however, conducted in all the districts of
Gujarat as per the time schedule. While the data at state and district level has been released by
the Census Authority, the same at village level is yet to be released by them. Hence, an attempt
was made to collect demographic particulars of the study area during the field survey. It has been
estimated that the population of the study area is 38,028. The table below presents the
demographic particulars of the study area.

Health Centres and Dispensaries in the study area.
Assessment of likely Socio-Economic impact
Impact on population composition
In general, no impact is envisaged on the population composition of the study area as there will
be no in-migration or out-migration of villagers. Since all the workers will be recruited locally
in-migration of people in search of job in the proposed mining project is not expected. Similarly,
chances of out-migration of people due to environmental degradation resulting from mining
activities are remote as Bauxite is not so lethal even if it is handled loosely. Hence, there will be
no negative impact on the population composition of the study area. If on the other hand, the
project proponent is compelled to recruit few highly skilled workers from distant places outside
the study area the impact on population composition will be insignificant or marginal.
Impact on employment
For removal of Bauxite the project proponent intends to recruit the local people. The total
number of people to be recruited will depend upon quantity of minerals to be extracted over a
period of time. In the initial period the number of such people will be less but gradually it will go
up when the extraction of minerals will pick up. It is definitely a positive impact of the proposed
mining project.
On an average 19 workers will be engaged for the operation of the mine to achieve the targeted
production of 5200 Ton per annum. Of the total number of workers proposed to be engaged for
extraction of mineral four will be skilled and two semi-skilled. Further, the mine lease holder has
decided to engage ten workers on piece rate basis. They will be paid their wages on the basis of

task performed during a given time period. The project will operate under the supervision of a
Mining Foreman having adequate experiences. Besides providing direct employment to the local
people there will be indirect employment for the informal sector, who is either Semi-Skilled and
or Un-skilled workers.

Piece rate is a system of making payment of wages to an employee. Under this system an
employee is paid for each unit of production at a fixed rate. Thus piece rate is the amount of
money paid per task performed or piece produced.
Increased supply of Bauxite for end users
Bauxite has about 100 uses. It serves as an excellent material for use as an aggregate in concrete
and asphalt, railroad ballast, rip-rap, or fill. It is also calcined in the production of cement and cut
into blocks of specific size known as "dimension stone." is used for acid neutralization in the
chemical industry, in stream restoration projects, and as a soil conditioner. Bauxite is used as a
road base material, drainage Material, roofing chipping, steel making industries, sugar soda ash
Industries and in formulation of other Household products. With the continuation of this project,
there will be increased supply of Bauxite. The states that will be benefitted by increased supply
of Bauxite will be Gujarat and the adjoining states.

Chapter-3Description of Environment
CRIPL III- 85
Scope for promotion of Bauxite based industries in the study area.
With increased supply of Bauxite in the region the prospective entrepreneurs shall have the
opportunity to set up Bauxite based industrial units for manufacturing drainage Material, roofing
chipping, rip-rap Bauxite for use in foundries. This will generate additional employment
opportunities for jobless in the region. This is a positive impact of the project.
Scope for development and maintenance of roads in the area
Movement of trucks, dumpers and other vehicles to and fro the quarry site is expected to increase
substantially, when the mine will start operating. The existing approach roads connecting the
quarry with the PWD road are narrow and uneven. There will be mud slides and traffic bottle
necks if the road is not widened and their surface conditions are not improved to support heavy
truck dumper traffic. Hence, there is a scope for development and maintenance of roads in the
area. This is a positive impact of the project.
Improvement in quality of life of the local people
The mining project proposes to provide gainful employment to 19 people. If a worker provides
his services for 275 days in a year and a sum of Rs. 160 is given to him per day as his wages
(Since revised from Rs.137 to Rs. 160) his household income will increase by Rs.44000 per
annum. This is a positive change in the consumption pattern of the household. The quality of life
will improve to those households who will be benefitted by getting employment in the above
mining project. This is a positive impact of the project.
Impact on state income
The upcoming mining project will make positive impact on state’s economy as state’s revenue
will increase due to higher collection of royalty, dead rent, taxes and fees. It is a positive and
direct impact of the project on State’s Gross Domestic product (SGDP).
Impact on Law & Order
As local people will be deployed to run the quarry, no law & order problem is envisaged. It is
expected that the workers will attend to their duties from their residences and return to their

homes after the day’s work is over. There would have ethnic issues and subsequent law & order
problem if the workers were migrants and lived in shanties close to the mining area. However, to
meet any untoward incident a police post may be set up close to the project area.
Check on illegal mining
Illegal Bauxite extraction has far reaching impacts on the society as it creates disturbances in the
social well being of the people. There are instances of indiscriminate violation of ‘Illegal Mining
Rules’ framed by various state governments. This has resulted to increase in the instances of
conflicts in the area. Majority of the people who are engaged in illegal Bauxite mining activities
are outsiders with criminal backgrounds. They force the local people in different ways to sell
their lands for extraction of Bauxite and those who oppose them are physically attacked. Conflict
between the criminal groups for the monopoly of Bauxite mining is a usual scene in many areas
across the country and in many cases it is fatal. In such cases the common people are helpless as
they are often threatened by the mafias. Further, illegal mining brings windfall gain to the
Bauxite mafias resulting to conspicuous expenditures especially on drinking, which again causes
law and order problem in the mining area and its surrounding areas. Thus illegal mining not only
bring loss to the Government revenue but also create law and order problems in the mining area.
The mining project has legal backing since the lease has been granted by the Government and the
miner will start operating the mine after the receipt of environment clearance and other
permissions from the Government. Such projects with legal backing are expected to put a check
on illegal mining and siphoning of government revenue.
Impact on health
Mining is always a health hazard and extraction of Bauxite is no exception to that. The major
health problem originates from mining of Bauxite is the generation of dust and other pollutants.
It exposes communities to airborne particulate matter that damages lungs of infants, children,
elderly persons and those with existing health problems. This must be checked when mine starts
operating, otherwise it will lead to permanent respiratory diseases.

health education resources, emergency response personnel and equipment, doctors, nurses and
hygienists. Furnished below are few steps need to be taken by the mine operator to meet any
health hazard during the course of mining practices.
Safe work environment
The project proponent must ensure health and safety of all the employees at work. He must
maintain safe work environment and ensure that the machinery and equipment in use are safe for
his employees. Further, he must make sure that work arrangements are non-hazardous to
employees.
Provision of first aid and regular health examination:
There should be provision for First Aid and the first aiders must be well trained in handling
patients working in mines. Periodical medical examination as per Mines Rule 1955 should be
undertaken for all the mine workers. This must be made compulsory for all workers engaged in
extraction of minerals. The regular health examination must cover treatment of serious back
injury; existing asthma or respiratory diseases, existing skin diseases, lung function test (pre and
post ventolin), Audiograms, Chest X- ray etc.
Health education:
Adequate health education and information related to the job must be provided to the workers.
Baseline health information should be recorded for future references.
Tie up with the nearest hospital for medical help
To meet the medical needs of the mine workers tie-ups with nearest hospitals should be made.
Efforts must be made to reserve few beds in the above hospitals for the workers of the upcoming
mining project. This will ensure timely medical aid to the affected persons.
Supply of mask, gloves etc.
The workers in the Bauxite mines are subject to respiratory diseases. For protection from dust it
must be made compulsory for all workers to wear masks and gloves, while working in a mine.

Chapter-3Description of Environment
CRIPL III- 89
Administration of anti-venom injections
Provision of Anti-venom therapy must be made available for administration to the workers in
case of snake, spider and insect bites, while working in the mine.
Special telephone number
A special telephone number should be made available to the workers in case of emergency so
that they can dial the same for medical assistances. Further, efforts may be made to provide
vehicles to the patients in short duration for shifting to the health institutions.
Special group insurance scheme:
All the mine workers must be covered under a Group Insurance Scheme of LIC or any other
Insurance company to achieve economic objectives and social obligations.
Perception of local people
During the course of site visit people living in the villages were requested to express their views
about this mining project in district Devbhumi Dwarka in Gujarat. Irrespective of the distance of
the villages from the mining site they all supported it. They stated that it should be given top
priority as the entire construction industry is depended upon it. However, people living in the
study area stated that extraction of Bauxite should be allowed with the following conditions:
a) All the persons to be deployed for extraction of Bauxite should be recruited locally from
Devbhumi Dwarka, in no case outsiders be engaged for the purpose.
b) There should not be any pilling of Bauxite for deferred sale. The piling of Bauxite may
create environment pollution.
c) The mud road connecting the quarry with the Tar road should be well maintained and
there should not be any pothole or uneven surface. This will ensure speedy transportation
of Bauxite from the quarry to the end users.
d) The local communities should be involved while implementing the CSR activities.
e) The CSR activities should be carried on under the supervision of a team drawing
members from affected villages.

f) The mining should be practiced every year since Bauxite never gets exhausted due to
regular replenishment during rainy season.
Corporate Social Responsibility
Corporate social responsibility (CSR) refers to responsibility of a company to ensure positive impact
on environment, consumers, employees, communities, stakeholders and all other members of public
sphere. Corporate involvement in local services is being increasingly encouraged for the expansion
of occupational welfare. It would be appropriate for the project proponent to undertake few
community development projects for the local residents. This will not only improve the socio-
economic status of the people but also enhance the reputation of the project proponent who has
selected the place for mining activity. During the field survey the selected households were
requested to state the needs of the community. Based on their replies the following four activities
have been identified, which could be taken up by the project proponent in order of preference.

Conclusion
The implementation of the Bauxite mining project at Mewasa will generate both direct and indirect
employment for the local aspirants. The issue of environment clearance to the mine owner will make
mining operation legally valid and it will bring income to the state exchequer. It is expected that
intending entrepreneurs will venture to set up micro and small scale units in the near future making
the area a mixed society, dependent on industry, trade and business. With the implementation of the
proposed mining project the occupational pattern of the people in the area will change making more
people engaged in mining, industrial and business activities rather in agriculture. Thus there will be a
gradual shifting of population from agriculture to mining and industry.

3.11 BIOLOGICAL ENVIRONMENT
The conservation and sustainable use of natural ecosystems and biodiversity is essential to support
sustainable development with biological resources providing raw materials for livelihoods,
sustenance, trade, medicine and industrial development. Protecting forests and other natural
ecosystems can provide a host of services that reduce human vulnerability to natural hazards along
with benefits of global value such as carbon sequestration, hydrological and geo-chemical cycling of
essential elements. In any Environment Impact Assessment study, it is necessary to identify the
baseline levels of relevant biological environmental parameters which are likely to be affected as a
result of the construction and operation of the planned project. Similar approach has been adopted
for conducting the Biological Environment study of the proposed Project. The biological study was
undertaken to understand the present status of terrestrial and aquatic ecosystems of the study area.
The baseline status has been ascertained for the following aspects:
3.11.1 Terrestrial Ecology
The study area covers core zone and 10 km around the project site. The plant species commonly
found in the area is given below. The information presented in this Chapter has been
collected through field studies, consultation with various government departments, local
resource person and collation of available literature with various institutions and organizations.
The climatic condition is semi-arid type and Juwar, bajra are the main crops during kharif season
and chilli during ravi season and the village people are mainly agriculture.
The nature of vegetation cover in this region is open, tropical dry deciduous type with thorny
shrub vegetation. Plantations have been done along the road side, and agricultural fields under
social forestry. The main species are Acacia nilotica, Azadiracta indica, Opuntia elatior,
Syzigium cumunii, Dalbergia sissoo, and Eucalyptus species. The vegetation is degraded due to
the human and live stock interference in this region. Herbs are abundant only during monsoon.
The vegetation in this region has been exploited in the past therefore the present condition is
degraded. Productivity of the agricultural crops in this region is very low because of poor soil

quality, infrequent and inadequate rainfall, water scarcity, and low consumption of fertilizer. The
floristic study reveals species composition, which represents poor gene pool uniformly spread in
restricted vegetation patches around human settlements. Collection of dead and dried branches
for fuel, hard wood and local trees for construction purpose, grazing practice on vegetated land is
also common.
Methodology
Reconnaissance survey
Reconnaissance field surveys were carried out by transect method for identification of various
forest patches in both core and buffer zones of the study area. As per the Reconnaissance survey,
most part of the buffer area is dominated by agriculture though some xerophytic vegetation like
acacia, kikar, khair, sisam occurs at high land while the river beds houses the salix, coconut etc.
Vegetation Study
Vegetation study was conducted in both buffer and core zones. The inventory of plants was
prepared through the field observations, personal interviews and group discussion. The species
composition revealed that plants are characterized by short stature, including annual or biannual
herbs and with spiny structures (thorns and spines), were classified as shrubs. Herb included
shade-loving, annual, biannual or perennial, herbaceous species. Any species which could not be
identified in the field was brought back (flowers/leaves specimen) and cross-checked with the
help of local expert institutions/resource person. Depending upon the vegetation, pattern of the
area, two methods were adopted for the study.
i) - Plot quadrate method
ii) - Belt transacts method
I- Plot quadrate method:
For present survey of plants, 10 m x 10 m plots were selected for the study of vegetation in the
study area.

The methods of calculation of different parameters are as given below:
(a) Diversity : Diversity was calculated with the help of Shannon &Weaver (1948) diversity index.
H = - Pi . loge Piwhere, Pi = n/N
n = No. of individual species.N = Total No. of species.
(b) Density : It was calculated as plants/ha by using quadrate methods.(d) Simpson’s Reciprocal Index 1/D is calculated where,
D = n (n-1) / N (N-1)
Where, n is no. of individuals of “i” th species and N is total number of individuals in data set.
Core Zone:-
The biological diversity of core zone is described as follows. The vegetation was dominated by
Acacia nilotica, Carissa congesta and millingtonia hortensis.
Buffer Zone:-
The buffer zone was devoid of any forest however the trees of Australian babul have been found
on the edges of agricultural fields and along pathways. These Australian babool seeds were
sprinkled by helicopters in Saurastra region of Gujarat during the period of Late Smt. Indira
Gandhi. Earlier the area was devoid of green cover as well. The main tree species found in the
buffer zone is given in Table 3.18.

Chapter-4Anticipated Environmental Impact and Mitigation Measures
CRIPL IV- 98
4.1 INTRODUCTION
Opencast semi-mechanized mining activity causes some adverse impacts on the surrounding
environment unless proper environmental management plan is adopted. Selecting suitable
sites for mining and also adopting all the guidelines prescribed by the Ministry of
Environment and Forests and Indian Bureau of Mines (IBM) can minimize the major possible
impacts. Mewasa Bauxite mine will take enough care in the mine to avoid adverse impacts on
the surrounding environment.
In this chapter, an attempt has been made to quantify the possible environmental impacts on
various features such as air, water, land, ecology and socioeconomic factors. The following
aspects have been studied to identify the impacts of the proposed production of the mine.
The magnitude and significance of the environmental pollution caused by mining depends on
method of mining, scale and concentration of mining activity.
4.2 AIR ENVIRONMENT
4.2.1 Anticipated Impacts
Bauxite mining is carried out by opencast semi mechanized mining method with Excavator-
Tipper combination ,Jack Hammer and Breaker. The air borne particulate matter generated
by ore and handling operations, and transportation of ore is the main air pollutant. The
emissions of Sulphur dioxide (SOx), Oxides of Nitrogen (NOx) contributed by diesel
operated excavation/loading equipment and vehicles plying on haul roads are marginal.
Prediction of impacts on air environment has been carried out taking into consideration
proposed production and net increase in emissions.
Air pollution sources in the operating mine have been classified into two categories:
i. Loading of ore
As per modified approved mining plan 5200 TPA production of Bauxite is target.
Project proponent is using number of one JCB having capacity 0.30 m3 of bauxite ore
per bucket. To achieve the target of 5200
MT in 300 working days, use of excavator is average 3.00 hours/day.
ii. Project proponent is using tippers for transportation having capacity of 8 MT/Tipper.
To achieve target of 17.0 MT/day the 2.1 say 2 trips are required. The route for
transportation is 800 m haul route & then it meets to state highway Harshad road. The

proposed increase in traffic density is not causing significant impact on the traffic
since the connecting road and nearby State Highway is capable of handling this
increase in traffic density. The trucks are always properly covered with tarpaulin and
overloading is not allowed to avoid spillage on roads.
iii. Water tankers with spraying arrangement are in use for regular water sprinkling on
the haul roads to ensure effective dust suppression. The tippers are well maintained
so that exhaust smoke does not contribute abnormal values of noxious gases and
un-burnt hydrocarbons.
In order to assess the impact due to Bauxite on air environment, prediction has been carried
out.
The prediction of Ground level concentrations (GLC) of pollutants emitted from the mining
activities will be carried out using ISCST-3 Air Quality simulation model released by
USEPA. This model is basically a Gaussian dispersion model, which considers multiple
sources. The model accepts hourly meteorological data records, to define the conditions of
plume rise for each source and receptor combination for each hour of input meteorological
data sequentially and calculates short term averages up to 24 hours.
The impact has been predicted over a 10 km radius area with mining area as the centre. To
obtain greater resolution, the receptors are defined with respect to 500 x 500 m grid point to
have better results. GLC have been calculated at every 500 m grid point to have better results.
4.2.2 Emissions Details
Excavation, loading and transportation through tippers are the major sources, which are of
significance. The quantity of particulate matter injected into the atmosphere, is a function of
tippers & excavator, horizontal area, quantity of charge and associated items. In modeling
emissions for each identified source, emission factors were obtained from the United States
Environmental Protection Agency (US EPA), 1995, AP-42 compilation of Air Pollution
Emission Factors. Emission rates for each identified source were determined using the
adopted emission factors and are given in Table 4.1.

4.2.3 Meteorological data
The meteorological data recorded continuously during the month of Oct 2018 to Dec 2018 on
hourly basis on wind speed, wind direction and temperature has been processed to extract the
critical 24 - hourly mean meteorological data as per the guidelines of IMD and MoEF.
Stability has been computed by Turner’s method and mixing height has been obtained from
publication of IMD “Atlas of Hourly Mixing Height in India, 2008. Wind rose diagram of the
observed meteorology is shown in Figure 4.2.
Fig 4.1: Wind Rose Diagram
4.2.4 Proposed mitigation measures for dust suppression
Bentonite, kaolin, and other clays often contain quartz, and exposure to quartz is causally
related to silicosis and lung cancer. Statistically significant increases in the incidence of or
mortality from chronic bronchitis and pulmonary emphysema have been reported after
exposure to quartz. Air pollution is caused mainly due to dust generation added with gaseous
emission from transportation activities along with mining operation like dozing, loading,
haulage etc. Proper mitigation measures will be practiced during mining activities to control
air pollution load below the prescribed limits. The same are as follows
Control of Fugitive Emissions
• Use of Personal Protection Equipments (PPE) like dust masks, ear plugs etc. by the mine
workers.

CRIPL IV- 101
• Regular water sprinkling on haul roads & loading points will be carried out.
• Development of green belt/plantation around the lease boundary, roads, dumps etc.
• Ambient Air Quality Monitoring will be conducted on regularly basis to assess the quality of
ambient air.
Prevention and control of Gaseous Pollution
• In mining activities, the sources of gaseous emissions are excavation & loading. Proper
maintenance of machines improves combustion process & makes reduction in the pollution.
Good maintenance and monitoring of fuel and oil will not allow significant addition in the
gaseous emission.
4.2.5 Model Results
The Air Quality Impact Prediction has been done by using “Industrial Source Complex Short
Term version 3 (ISCST3), of USEPA”. The main sources of air pollution with regard to the
proposed project for the purpose of estimation of increase in PM10 are identified due to –
(i) Excavation
(ii) Loading/unloading of ore
(iii)Transportation of ore by trucks on the Haul roads from mining benches.
Combined impact of PM10 was considered due to mining activities occurred simultaneously
on various sampling locations is given in table below.

4.2.6 Discussion of Results and Conclusion
ISCST3 - Model was used for prediction of impact of PM10 during conditions i)
Loading/unloading and ii) transportation of ore by trucks on Haul roads by using area source
model to predict GLC of PM10 during these conditions. Prediction was made with emission
values due to loading / unloading and transportation of ore by trucks on haul road. Total
predicted 24-h maximum GLC of PM10 at project site was 86.12 µg/m3 occurred at the
project site after superposition of base-line value 94.41 µg/m3 over the incremental
8.29µg/m3 due to combined impact of loading and unloading and transportation over the haul
road. Meteorological data under worst case scenario providing 24-h maximum average GLC
was discussed and given in Table 4.3.

4.3 NOISE ENVIRONMENT
Noise generated at the mine is due to semi-mechanized mining operations and truck
transportation activities. The noise generated by the mining activity dissipates within the
mine. There is no major impact of the mining activity on the nearby villages. However,
pronounced effect of above noise levels is felt only near the active working area.
The impact of noise on the villages is negligible as the villages are far located from the mine
workings. Since there is no involvement of major machinery, the impact of noise levels will
be minimal.

4.3.1 Noise Abattement and Control
Proper maintenance, oiling and greasing of machines at regular intervals will be done to
reduce the generation of noise.
Adequate silencers will be provided in all the diesel engines.
Blast holes will not be overcharged.
Plantation along the sides of approach roads, around office building and mine area will be
done to minimize the propagation of noise.
Personal Protective Equipments (PPE) like earmuffs/earplugs will be provided to all
operators and employees working near mining machineries or at higher noise zone.
Periodical noise level monitoring will be done.
4.4 WATER ENVIRONMENT
Mining activities cause adverse impacts due to mine drainage, siltation due to storm water
and contaminated water from workshops and domestic sewage water. Various components
have been identified for study of impact of the mine operations. Details of the same are given
below:
4.4.1 Impact on surface water bodies and control measures
As there is no seasonal nalla or water body within the leasehold area, therefore, no change
will be observed due to mining operation There is only seasonal water courses/nalla in the
buffer zone. Since there is no river or any perennial water course in the applied area,
diversion will not be required. There is no toxic element in and around the applied area or in
OB or ore. Hence contamination of any nature is not expected for surface or any ground
water source.
4.4.2 Impacts on ground water table and control.
Ground water in the area is saline in general and salinity increases with passage of time after
monsoon as the water table goes down. Water for drinking purpose is brought by tankers
from Mewasa village. Besides above rainy water will be collected in working pits and of pits
within nearby mines, which will be used for plantation purposes and dust suppression. The
water table in the area is 18m below the ground level during monsoon period. The mining
activity has been restricted up to a moderate depth. Therefore the mining activity in the
leasehold area will not make any impact on ground water.

4.4.3 Impact on water quality and control measures
The mining operations being opencast semi mechanized mining, adverse impacts are likely to
arise if proper control measures are not implemented. The following are the areas where
adverse impacts are envisaged in respect of surface water quality:
Wash-off from the dumps
Soil Erosion
No waste dumps will be formed in the subject mine due to absence of overburden. The
lateritic soil will be used as blanket on the worked out area of the pits for taking up
afforestation. As such no wash off from the dumps or soil erosion is expected.
4.4.4 Water consumption and wastewater generation
The total water consumption in the Mewasa Mine is about 4 KLD. The water is used in the
following purposes (i) For dust suppression (ii) for domestic consumption and (iii) for
greenbelt development.
The source of requirement met from the private water suppliers and water collected in the pits
of mine.
Breakup is given in the water balance as per Table 4.2.1:

After removal of ore body, a flat portion will be created in place of ridge and small benches
will be formed along the slope. All the broken area will be thoroughly afforested in planned
manner, so that landscape of the area is improved.
The measures to be taken are likely to bring forth positive impact on the core zone landscape.
The aesthetic environment of the core zone will have a positive impact by the time mining
ceases in the area with proposed thick afforestation.
4.5.3 GREENBELT AND PLANTATION
The future mining will hardly effect the existing vegetation. However, plantation will be
taken up in the area to upgrade environment and the scenic beauty of the area. The soil
generated during mining plan period will be spread at statutory barrier. Soil generated during
mining plan period will be spread on statutory barrier for plantation.
The afforestation is proposed over the statutory barrier. The afforestation is proposed from
first year of mining as shown in reclamation plan.
The proposed afforestation is given below in a tabular form. While calculating number of
saplings to be planted, the spacing of plants is considered as 5m2 area. The survival rate of

The following characteristics should be taken into consideration while selecting plant species
for green belt development and tree plantation.
• They should be fast growing and tall trees.
• They should be perennial and evergreen.
• They should have thick canopy cover.
• Plantation should be done in appropriate alternate rows around the proposed site to
prevent lateral pollution dispersion.
• The trees should maintain regional ecological balance and conform to soil and
hydrological conditions. Indigenous species should be preferred.
4.6 BIOLOGICAL MANAGEMENT MEASURES
There is a requirement to establish a stable ecosystem with both ecological and economic
returns. Minimization of soil erosion and dust pollution enhances the beauty of the core and
the buffer zone. To achieve this, it is planned to increase plantation activities. The basic
objectives of plantations are as follows:-
Improvement of Soil quality
Quick vegetative cover to check soil erosion

4.7 Greenbelt Development Plan
Green belt is plantation of trees for reducing the air pollution as they absorb both gaseous and
particulate pollutant, thus removing them from atmosphere. Green plants form a surface
capable of absorbing air pollutants and forming sinks for pollutants. It improves the aesthetic
value of local environment. Under present project, green belts have been planned with
emphasis on creating biodiversity; enhance natural surroundings and mitigating pollution.
The greenbelt development plan aims to overall improvement in the environmental
conditions of the region. The plan with a five-fold objective addresses issues such as
providing sink for air pollutants likely to emitted from the project; enhancing the forest cover
for increasing the biodiversity of the region; providing aesthetic value to the project area
enhancing the ecological equilibrium of the area; and to a large proportion in combating soil
erosion.
Afforestation on degraded forest area, forest protection / conservation will be
carried out every year by the mine owner
This activity will promote the emergence of the primary succession species, hence
it will be a silvicultural operation, extremely important for maintaining ecology
and environmental health of the area
This helps in regeneration & establishment of pioneer plant species saving expose
land & land cutting
The scheme of plantation around the project site is given as follows:
1. Afforestation will be put under a protective regulatory framework to ensure that it is
not Degraded or disturbed. No ecologically disruptive activity will be allowed in this
zone.
2. Afforestation will cover a total of statutory barrier area of lease
.
The plants recommended for afforestation are as follows.

Impacts on Biodiversity
Present data have been collected through direct inventory as well as various Government
Departments such as forests, agriculture, fisheries, animal husbandry and various offices to
establish the pre-project biological environmental conditions. There are no endangered
species, wildlife sanctuary, wildlife corridors, faunal migratory routes or eco-sensitive area
near the whole study area. Save the flora/fauna around the project area, is one of the basic
objective of present project. For this, mine owner agency planted a good roadside plantation
along both side of the mine road.
Impacts on agriculture
Agriculture activities are practiced nearby areas may impacted because of dust generation
but mitigative measures such as regular water sprinkling on active areas for example hole
roads, dump sites should be strictly followed so that impact is minimized.
4.8 SOCIO ECONOMIC ENVIRONMENT
The mine area does not cover any habitation. Hence the mining activity does not involve any
displacement of human settlement. No public buildings, places, monuments etc exist within
the lease area or in the vicinity. The mining operation will not disturb/ relocate any village or
need resettlement. Thus no adverse impact is anticipated.
The impact of mining activity in the area is positive on the socio-economic environment of
the region. Meawasa Bauxite mine is providing employment to local population and it will be
give preference to the local people whenever there is requirement of man power.

6.1 INTRODUCTION
Success of any environmental management program depends upon the efficiency of the
organizational set up responsible for the implementation of the program. Regular monitoring
of the various environmental parameters is also necessary to evaluate the effectiveness of the
management program so that the necessary corrective measures can be taken in case there are
some drawbacks in the proposed program. Since environmental quality parameters at work
zone and surrounding areas are important for maintaining sound operating practices of the
project in line with conformity with environmental regulations, the post project monitoring
work forms part of EMP. Monitoring program will be followed till the mining operations
cease; every year as per the schedule below:
6.1.1 AIR QUALITY MONITORING
One location in core zone and eight locations in the buffer zone will be monitored for once
per season except monsoon.
6.1.2 NOISE LEVELS MONITORING
Noise levels in the working area will be monitored once in every month till the continuation
of operations. Ambient noise levels will also be monitored once in a season in the buffer zone
to evaluate the noise levels in surrounding community.
6.1.3 WATER QUALITY MONITORING
Water environment will be assessed periodically for both surface water and ground water.
Surface water quality will be monitored at identified ponds/lakes during all four seasons.
Surface water flow through the major nalla down stream will be measured at least once a
month during monsoon and co-relate with the total rainfall during the season to estimate the
relative changes, if any. Ground water level and quality on seasonal basis will be assessed in
the open/dug wells to evaluate the impacts of ongoing operations. Water levels will also be
monitored on seasonal basis in surrounding wells.
6.1.4 PLANTATION
Before the onset of monsoon season, will be done progressively till the final closure of the
mine. Plantation will be done in 33% area of lease. It is proposed to plant sapling of 550
trees.

CRIPL IX- 132
ENVIRONMENTAL MANGEMENT PLAN
The environmental management plan consists of the set of mitigation, management,
monitoring and institutional measures to be taken during the implementation and operation of
the project, to eliminate adverse environmental impacts or reduce them to acceptable levels.
The present environmental management plan addresses the components of environment,
which are likely to be affected by the different operations in a mine area.
The mitigation measures which reduce the impact have already been identified earlier in this
report. To minimize the adverse impact, certain additional EMP is enumerated below for
implementation.
9.1 ENVIRONMENTAL MANAGEMENT PLAN (EMP)
Proper environmental management plan are proposed for “Mewasa Bauxite mine” mining
project to mitigate the impact during the mining operation.
• Control of Fugitive Emissions.
• Prevention and control of Gaseous Pollution.
• Minimization of waste generation and pollution.
• Judicious use of natural resources and water.
• Safety, welfare and good health of the work force and populace.
• Ensure effective operation of all control measures.
• Vigilance against probable disasters and accidents.
• Monitoring of cumulative and long time impacts.
• Plantation along the sides of approach roads, around office building and mine area will be
done to minimize the propagation of noise.
• If wild animals are noticed crossing the core zone, it will not be disturbed at all.
• Labors will not be allowed to discards food, plastic etc., which can attract animals near
the core site.
• Only low polluting vehicle will be allowed for carrying ore materials. All vehicles
allowed in the project site area will have to provide pollution under control certificate at
the end of three months

CRIPL IX- 133
9.2 ENVIRONMENTAL MANAGEMENT PLAN IMPLEMENTATION
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 programme has to be prepared.
The major attributes of environment are not confined to the mining site alone.
Implementation of proposed control measures and monitoring programme has an implication
on the surrounding area as well as for the region. Therefore, mine management should
strengthen the existing control measures as elaborated earlier in this report and monitor the
efficacy of the control measures implemented within the mining area relating to the following
specific areas:
a) Collection of air and water samples at strategic locations with frequency suggested and
by analyzing thereof. If the parameters exceed the permissible tolerance limits, corrective
regulation measure will be taken.
b) Collection of soil samples at strategic locations once in every year and analysis thereof
with regard to deleterious constituents, if any.
c) Measurement of noise levels at mine site, stationary and mobile sources, and adjacent
villages will be done in every quarter of the year.
d) Innovations would be carried out at our mine for minimizing adverse impact of blasting
along with following measures will be adopted at mine to reduce ground vibration, fly rocks,
dust generation, noise generation, etc.
e) The waste generated during modified mining scheme period will be backfilled in mined
out land. As backfilling material is less as compared to depth of excavated area, hence part of
the mined out area will be backfilled and will be carried out plantation & rest will be
developed as water reservoir.
Mine management will be in regular touch with local surrounding villages to update the
various developmental schemes made by them. They will also consider any immediate
requirement, which could be taken care of in near future.
An Environmental Management Cell (EMC) is envisaged which will be responsible for
monitoring EMP and its implementation. EMC members should meet once in a month to
assess the progress and analyze the data collected during the month.

Chapter-9Environment Management Plan
CRIPL IX- 134
EMC will be in regular touch with State Pollution Control Board and send them regular
progress report. Any new regulations considered by State/Central Pollution Control Board for
the industry will be taken care of.
9.3 PROPOSED SET UP
Keeping the utility of monitoring results in the implementation of the environmental
management program in view, an organizational chart has been proposed, headed by General
Manager as shown below.

10.9 ANALYSIS OF ALTERNATIVES
In the proposed project, an opencast manual mining will be carried out. For that, no other
methodology is going to be changed, depending upon the geological set up, strata of the rock,
boulders and its structural behavior. So, all the parameters of EIA/EMP will be implemented
as per the open cast mining.
10.10 DESCRIPTION OF ENVIRONMENT
This section contains the description of baseline studies of the 10 km radius of the area
surrounding “Meawsa Bauxite Mine”. The data collected has been used to understand the

impacts of the project can be assessed.
Environmental data has been collected in relation to propose mining for:-
(a) Land
(b) Water
(c) Air
(d) Biological
(e) Noise
(f) Socio-economic
10.11 AMBIENT AIR QUALITY
The results of AAQ are given in Chapter-3, the results of PM10 recorded within the
study area was in the range of 57.8 µg/m3 to 89.7 µg/m3 , the result of SO2 recorded within
the study area was in the range of 4.7 µg/m3 to 13.3 µg/m3, the result of NOx recorded within
the study area was in the range of 6.3 µg/m3 to 22.9.
10.12 NOISE ENVIRONMENT
The values of noise observed in some of the areas are primarily owing to vehicular traffic and
other anthropogenic activities. Assessment of hourly night time Leq (Ln) varies from 53.0 to
39.8 dB (A) and the hourly daytime Leq (Ld) varies from 51 to 62.5 dB (A) within the study
area.
10.13 WATER ENVIRONMENT
The water quality in the impact zone was assessed through physico- chemical and
bacteriological analysis of ground water samples. The results have been compared with the
drinking water quality standards specified in IS: 10500. It was observed that all the physico
chemical parameters and heavy metals from surface and ground water samples are below
stipulated drinking water standards.
All the ground water samples analyzed can be considered fit for drinking purpose in the
absence of alternate sources.

10.14 SOIL ANALYSIS REPORT
Physical characteristics of soil were characterized through specific parameters viz bulk
density, porosity, water holding capacity, pH, electrical conductivity and texture. Soil pH
plays an important role in the availability of nutrients. Soil microbial activity as well as
solubility of metal ions is also dependent on pH. In the study area, variations in the pH of the
soil were found to be neatral (7.43 to 7.76). Electrical conductivity (EC) is a measure of the
soluble salts and ionic activity in the soil. In the collected soil samples the conductivity
ranged from 359.0 to 375.3 µmhos/cm. The soils with low bulk density have favorable
physical condition where as those with high bulk density exhibit poor physical conditions for
agriculture crops.
10.15 BIOLOGICAL ENVIRONMENT –
The lease area as well as buffer zone area reveals no endangered and endemic species of flora
and fauna in the area.
10.16 WATER REQUIREMENT
The total water consumption in the Ran Mine is about 4 KLD. The water is used in the
following purposes.
For dust suppression.
For domestic consumption
For greenbelt development.
The above water will be met from the private water suppliers and water collected in the pits
of mine.
The following table shows the water balance of the mine activity:

i. Air quality modeling
In order to predict the particulate emissions, Gaussian’s mathematical expression will be used
to predict changes in air quality i.e., maximum ground level concentration (GLC’s) of
particulate matter, due to the various mining activities of the proposed mine.

10.18 ENVIRONMENTAL MANAGEMENT PLAN
The mining activities involve, dozing, excavation, loading, haulage and transportation of
Bauxite. These activities lead to generation of air borne dust, which can cause air pollution in
and around the mining lease area, if appropriate control measures are not taken. Similarly
mining causes land degradation, noise and water pollution etc. in the area.

CRIPL X- 146
In order to minimize impacts of mining on different environmental parameters and to keep air
and water quality within prescribed limits of CPCB, a rapid Environmental Management Plan
(EMP) is prepared to strictly follow it. This helps in resolving all environmental and
ecological issues due to mining in the area. The environmental management plan includes all
measures and safety precautions necessary for safe mining along with rehabilitation measures
for mined out areas.

10.19 CONCLUSION
As discussed, it is safe to say that the proposed facilities are not likely to cause any
significant impact to the ecology of the area, as adequate preventive measures will be adopted
to keep the various pollutants within the permissible limits. Green belt development around
the area will also be taken up as an effective pollution mitigative technique, as well as to
serve as biological indicators for the pollutants released from the premises of “Mewasa
Bauxite Mining Project”.
