1.7 Importance to Country and Region
1.7.1 Importance to Country
Limestone is very important mineral and is the principal raw material for the
production of soda ash and clinker for cement etc. The need for mining of the
chemical grade limestone from the project (mine lease area) has arisen to
meet the current situation of demand supply gap faced by company.
Limestone Mining is a very important economic activity in Gujarat region of
Gujarat. Chemical Grade Limestone is mainly found in this region. This high
purity limestone is essential for Soda Ash manufacturing. For Soda Ash

industry to remain competitive, availability of chemical grade lime stone in
nearby area is extremely important.
The Soda Ash based limestone mining industry contributes significantly to
the State Gross Domestic Product and provides direct employment to nearby
laborers. Additional jobs are created by way of transportation and related
jobs, ancillary to mining. Subject mine lease aims to augment the limestone
supply to company‘s own Soda Ash plant, Sutrapada.
The products of Company‘s Soda Ash Plant, Sutrapada, especially soda ash,
are a vital input for a number of basic industries such as glass, pulp & paper,
chemicals and detergents besides others. Consequently, this project aims at
keeping many of the key industries within the country well supplied with an
essential raw material.
1.7.2 Importance to Region
About 36 local people will be employed for the proposed mining activity which
will create ample opportunities for employment to local population. On the
other hand, by Limestone production, the applicant will pay revenue in the
form of royalty, dead rent, direct and indirect taxes which will contribute and
generate additional revenue to the region. Besides this, the project will prove
beneficial in terms of socio - economic development.

Regional Rock Type:-
The Deccan traps are extrusive rocks occurring as undulating terrain. Some
of the Igneous rocks occurring in ―Gir Forest‖ area are intrusive ultrabasic
rocks, containing mineral like greenish Nepheline, Augite & Hornblende.
The miliolitic limestone is unconformably lying on Gaj formation, which are
older than miliolitic limestone. The Gaj limestone is hard, compact and
contained silicified fossils. The Gaj clay is associated with Gaj limestone. The
economically important miliolitic limestone is compact to semi compact
aggregates of miliolamicro organism shells. Current bedding is more due to
shallow water deposition. The limestone thickness varies from thin layer upto
20-30 m and more.
2.3.2 Local Geology
In the entire area limestone is extensively in low height elongated
mounds/elevated ground with patches of thin soil cover and surrounded by
soil covered cultivated fields. The limestone shows variation in CaO
constituents in compact and semi-compact limestone. The compact type
shows micro crystalline due to enrichment of calcium which commonly occurs
near to surface followed by semi compact type. Below the semi compact good
cement grade limestone is available with somewhat more silica content. The
compact and semi compact type limestone of chemical grade is suitable for
the Soda Ash manufacturing. Cement grade limestone of CaCo3 content less
than 90% and SiO2 more than 5.5% is not suitable for the Plant. This may be
utilized for Cement manufacturing at later date.

cement grade. The chemical grade and cement grade limestone categorization
is based on CaO and SiO2 variation depending on enrichment due to leaching
of SiO2 by solution activities.
Normally, the cement grade limestone occurs below the chemical grade
limestone of semi compact type. In bottom the Gaj clay is lying there, as a
departure from above at two places.
Lithology:
The entire area is mostly exposed by Miliolitic formation and rarely cover of a
layer of soil attaining a maximum thickness of about 15-30 cms.
The local stratigraphic sequence observed in the area is as follows:

Limestone of the area is a porous rock containing minute empty spaces and is
also severely affected by the solution effect of percolating water resulting in
innumerable minute cavities and voids within the otherwise massive rock. It
shows prominent dune type current bedding with bedding dips ranging
between 5° to 10° towards the south-east in general.

2.4 Proposed Method of Mining
The proposed Limestone mine will be developed by manual open cast mining
which includes excavation, loading, transport and dispatch of mineral to end
users.
2.4.1 Open Cast Mining
The mining will be done by manual open cast method. The configuration of
the lease area is irregular polygon shape, elongated along North – west –
south – east direction. The area is also interspersed by agricultural field (part
of the lease area without surface right) and encroached area etc.
Presently mining is going on the site of proposed mining by manual opencast
method of mining. Drilling is being carried out by jack hammer. Blasting is
carried out by ANFO and High explosive booster charge. Blasted Material is
being sized manually then loaded manually into truck / dumpers.
Mining is being carried out in benches with maximum height of 1.5 mts. and
width of the benches is maintained more than height of the bench. Slope of
the benches is being maintained at 60⁰. Each pit has approach road of
gradient 1:16 as marked in the surface plan.
Taking into consideration shape and nature of deposit and the targeted
production the mine will continue to be worked by manual opencast method
of mining. Attempts have been made to design and exploit the deposit with
minimum damage to environment and optimal utilization of limestone for
Soda Ash industry The ultimate working depth will not intersect the ground
water table.
2.4.2 Salient Features of Mining Method
The salient features of proposed mining method are:-
The height of the bench will be maintained at 1.5m.
Width of the benches is maintained more than height of the bench
Mining will be done from top to bottom.
Considering the stability of rocks, the final slope or say ultimate pit slope
is proposed 45° from vertical.
Transportation of the mineral from mine to end users will be done by
hired trucks.

3.3 Study Period
The baseline environmental quality represents the background scenario of
various environmental components in the study area. As part of
Environmental Impact Assessment Study, baseline environmental
monitoring was carried out for summer season covering the months of March-
April - May 2017.
3.4 Land Environment
Land Cover is the physical material at the surface of the earth (it includes
grass, asphalt, trees, bare ground, water etc.) whereas Land use is the
human use of land. Land Use involves the management and modification of
natural environment or wilderness into built environment such as fields,
pastures and settlements. It has also been defined as "the arrangements,
activities and inputs people undertake in a certain land cover type to
produce, change or maintain it". Studies on land use aspects of eco-system
play an imperative role in identifying susceptible issues and to take
appropriate action to uphold ecological equilibrium in the region. The main
objective of this section is to provide a baseline status of the study area,
covering 10 km radius around the mining lease so that temporal changes due
to the mining activities on the surroundings can be assessed in future.
3.4.1 Objective of the Study
The objective of the land use study is given below:
To develop land use & land cover map using land coordinates of the
project area.
To identify and mark important basic features according primary and
secondary data.
To suggest measures for conservation and sustainable use of land.

3.6 Seismicity of the Study Area
The study area comes under Zone-III i.e. low damage risk zone. Many parts of
the Indian subcontinent have historically high Seismicity. Seven catastrophic
earthquakes of magnitude greater than 8 (Richter scale) have occurred in the
western, northern and eastern parts of India and adjacent countries in the
past 100 years. By contrast, peninsular India is relatively less seismic,
having suffered only infrequent earthquakes of moderate strength. The main
seismogenic belts are associated with the collision plate boundary between
the Indian and Eurasian plates. The mine site as well as study area lies in
Zone-III of Seismic Zoning Map. The Seismic Zone Map of Gujarat is shown
in Figure 3-5.

3.10 Ambient Noise
Noise is defined as an unwanted sound. The acoustic environment varies
dynamically in magnitude and character throughout in most of the
communities. The noise level variation can be temporal, spatial. It interferes
with speech and hearing and is intense enough to damage hearing or is
otherwise annoying. The definition of noise as unwanted sound implies that
it has an adverse effect on human beings and their environment. Noise can
also disturb natural wildlife and ecological system. Sound is mechanical
energy from a vibrating surface, transmitted by cyclic series of compression
and rarefaction of molecules of the materials through which it passes. Sound
can be transmitted through gases, liquids and solids. The number of
compressions and refractions of the air molecules in the unit of time is
described as its frequency. Frequency is expressed in hertz (Hz), which is the
same as the number of cycles per second.

3.10.1 Methodology of Ambient Noise Monitoring
Instant Sound Level Meter (SLM) is used for the collection of data related to
noise at an interval of one hour. The day noise levels have been monitored
during 6:00 AM to 10:00 PM and night noise levels during 10:00 PM to 6:00
AM at six locations in the study area. Measured noise level displayed as a
function of time provides a useful scheme for describing the acoustical
climate of a community. Noise levels recorded at each station are computed
for equivalent noise levels. Equivalent noise level is a single number
descriptor for describing time varying noise levels. The equivalent noise level
is defined mathematically as:-
10 Log1/ T Σ (10Ln/10)
Where L = Sound pressure level a function of time dB (A)
T = Time interval of observations
3.10.2 Noise Monitoring Locations
The hourly Leq noise levels were recorded at nine locations in the study area;
sampling locations are given in Table 3-13, and also shown in Figure 3-9.

3.11 Hydrology and Physiography of the Study Area
3.11.1 Hydrology
Deccan Traps, Gaj Beds, Miliolite Limestone, and Alluvium from the aquifer
system in the district. The deccan Traps and gaj beds formation constitute
both confined unconfined aquifers, the alluvium and the miliolite limestone
form unconfined aquifer only. These unconfined aquifer occur in hydraulic
continuity and act as a single aquifer system.
The extent of the miliolite limestone aquifer is restricted to the coastal ridge
and depression and the southern fringe of the plains. Further, in land occurs
the unconfined Guj aquifer. The inland depressions and the ‖ gheds‖ are
underlain by this aquifer. The remaining part of the district is underlain by
Deccan trap aquifer and constitutes almost 60% of its total area.
(a) Ground Water in Deccan traps:
This is the most important and the most widespread aquifer in the
district.
Salient Features:
- Aquifer material : Massive and Amygdaloidal basalt
- Nature of aquifer : Upper un- confined -20m(thickness)
Lower confined -25m (thickness)
- Nature of porosity : Secondary (weathered material, fractures and
shears)
- Quality : Good
The depth of water level varies from 2 to 24 meters below ground level: yields
of the wells varies from 10 to 1370 m3/day.
(b) Ground water in Gaj formation:
Salient Features:
-Aquifer material : Limestone, grit and sandstone
-Nature of aquifer : Upper unconfined -30 m (thickness)
: Lower confined – 15m (thickness)

-Nature of porosity : Primary & Secondary (pores, fractures and solution
cavities)
- Quality : Good to bad (lower aquifer saline)
The depth of water level varies from near surface to 27 meters below ground
level. The yield of the wells varies from 1 to 1110 m3 /day, the average yield
being 196.61 m3 /day.
( c ) Ground Water in Milliolite Limestone : This aquifer constitutes an
important source of portable water in the coastal parts of the district. The
ground water in this aquifer occurs under unconfined conditions and its
movement is controlled by the porosity and the karstic nature of the
limestone.
Salient features:
- Aquifer material : Limestone
- Nature of aquifer : Upper unconfined > 40 m(thickness)
- Nature of porosity : Primary and Secondary
- Quality : Good to bad
The depth of water level ranges from 2 to 8 meters below ground level. The
yield of the wells varies from 15 to 2549 m3 /day. And their average yield is
210 m3 /day.
(d) Ground water in Alluvium:
Salient Features:
- Aquifer material : Fine grained sand, Silt
- Nature of aquifer : Upper un confined -30m (thickness)
The depth of water level ranges from 2 to 13 meters below ground level. The
yield of the wells varies from 25 to 121 m3 /day.
( e) Depth to water level and water level fluctuation:
In general, the depth of water level varies between 5 to 15 meters below the
ground level. The quantum of seasonal fluctuation in the water table in the
area varies from year to year

and place to place. The average change in the water level between pre
monsoon and post monsoon period varies from 5 to 10 meters.
( f) Chemical Quality:
A generalized account of the range of different chemical constituent in the
region is as under:
pH 7.3 to 8.6
Ca 8.0 to 552 ppm
Mg 5.0 to 411 ppm
Cl 28 to 3829 ppm
Co3 Nil to 96 ppm
HCO3 85 to 1244 ppm
Total Hardness (as Caco3) 40 to 2810 ppm
Electricity Conductivity
(in micromohs/cm at 25oC) 378 to 15850
(g) Ground Water Recharge:
Rainwater infiltration is the principal source of recharge to the ground water
body in the region. Amongst other sources of recharge are return flow of
irrigation water, seepage from surface water sources e.g, canals and tanks
and influent seepage from the streams, all of witch contribute in replenishing
the ground water body.
(h ) Ground Water Drainage:
Ground water is discharged from the area by evapo-transpiration from
shallow water tracts along stream beds, vicinity of tanks and areas of shallow
water table tracts by natural sub surface flow as base flow into stream and
withdrawal by wells for irrigation and other purpose.

3.13 Biological Environment
An ecological study of the ecosystem is essential to understand the impact of
industrialization and urbanization on existing flora and fauna of the study
area. Studies on various aspects of ecosystem play an important role in
identifying sensitive issues for undertaking appropriate action to mitigate the
impact, if any. The biological study was undertaken as a part of the EIA
study report to understand the present status of ecosystem prevailing in the
study area, to compare it with past condition with the help of available data,
to predict changes in the biological environment as a result of present
activities and to suggest measures for maintaining its health. A survey was
conducted to study the flora & fauna in 10 km radius. Some of the
information was gathered from the local habitants. All the collected data
were classified to interpret the impact of pollution on the flora and fauna of
that region. Survey of the wild plants as well as cultivated crop plants was
made and all the available information was recorded. Methods used for
identifying flora and fauna are given in Table 3.20

3.13.4 Cropping Pattern
The climatic conditions of a region affect the agricultural cropping pattern of
different areas. Thus, it produces different crops. Amongst a host of climatic
factors i.e. rainfall, temperature, humidity, wind velocity and duration of
sunshine etc. affect the cropping pattern in a significant way. Annual rainfall
and its distribution over the entire year and the regimes of diurnal and
annual temperatures are by far, the prominent factors affecting agriculture
and the life style of the people. Cropping pattern is shown in .Table 3.23.

3.14 Socio Economic Environment of the Study Area
An essential part of environmental study is socio-economic environment
incorporating various facts related to socio-economic conditions in the area,
which deals with the total environment. Socio economic study includes
demographic structure of the area, provision of basic amenities viz., housing,
education, health & medical services, occupation, water supply, sanitation,
communication, transportation, prevailing diseases pattern as well as feature
of aesthetic significance such as temples, historical monuments etc. at the
baseline level. This would help in visualizing and predicting the possible
impact depending upon the nature and magnitude of the project.
Socio-economic study of an area provides a good opportunity to assess the
socioeconomic conditions of it. This study will possibly make a change in
living and social standards of the particular area benefitted due to the
Project. The gross economic condition of the area will be increased
substantially due to the existence of this project. It can undoubtedly be said
that this project will provide direct and indirect employment and improve the
infrastructural facilities and standards of living of the area. The fabrics of
socio-economic changes are so complicated that this study would seem to be
extremely limited, almost superficial and at time subjective in nature. More

thorough and quantified socio-economic study will undoubtedly require vastly
longer time and resources and is, therefore, beyond the scope of the present
EIA study. The EIA will give a reasonably clear picture of the socio-economic
conditions prevailing in the study area.
3.14.1 Objective of Socio Economic Study
The objectives of this socio-economic study are:
To conduct socio-economic assessment study in Project Area.
To know the current socio-economic situation in the region to cover the
subsectors of education, health, sanitation, water and food security.
To recommend practical strategic interventions in the sector.
To help in providing better living standards.
To provide employment opportunities.
3.14.2 Scope of Study
The scope of socio economic study area as follows:
To study the Socio-economic Environment of area from the secondary
sources.
To develop a questionnaire for SIA Survey.
Data Collection & Analysis.
Prediction of project impact.

3.14.3 Methodology
For socioeconomic study, both qualitative and quantitative methods were
adopted. Data regarding the field area were collected both from primary as
well as secondary sources. Primary sources include data collected through
direct field sampling, observations based on schedules, questionnaires etc. A
suitable format of Questionnaires was developed by us & survey was
conducted. Secondary sources include various reports, records, literatures,
documents, maps, charts and photographs etc, collected from various public
and private organizations. To know the perception of local people on socio-
economic impact of Lime Stone mining in the area, a field survey was
conducted during March- May 2017. The target groups were selected from

villages of core and buffer area of Veraval Tehsil. About 25 people were
interviewed to get response. Focus Group Discussion (FGD) and Participatory
Rural Appraisal (PRA) techniques are the two important tools of
participatory method used in the field. Household level contacts and
interviews have been undertaken with each family for completing the
household socio-economic profile. For individual farmers and community
members, qualitative interviews were used since this approach allows a more
in-depth investigation into the each interviewee. It also allows people to
speak for themselves without their answers being biased by predetermined
hypothesis-based questions. The questionnaire was basically focused to
gather respondents´ views from the study areas on the impacts of mining.
The data collected from various sources were processed, computed and
tabulated to fit the problem. These tabulated data were interpreted and
analyzed with the help of various quantitative techniques. More thorough
and quantified socio-economic study will undoubtedly require vastly longer
time and resources and is, therefore, beyond the scope of the present EIA
study. The EIA will give a reasonably clear picture of the socio-economic
conditions prevailing in the study area.
3.14.4 Background of Study Area
The study area is defined as 10 km radius of the periphery of mine lease
boundary. About 35 villages of Tehsil Veraval District Gir Somnath was
falling in this study area. The socio-economic parameters i.e. population
growth, density, literacy etc. played an important role in determining the
impact of the proposed activity directly or indirectly on the human population
of the study area. These impacts may be beneficial or detrimental. This study
area falls in lowest part of Gujarat state in western India. It lies in Veraval
Tehsil of Gir Somnath District in Gujarat State, India. The Tehsil Head
Quarters is veraval town of Gir Somnath district which is located 7.5 km in

The table shows that out of total population only 48741 (60.11%) are literates
and 27661 (34.11 %) are illiterates. Out of total literate population, there are
57.67% male literates while female literates are 43.32% only in the region.
Among illiterates there are 39.22 % male and 60.81 % females to total
illiterates. This analysis shows that literacy in the region is low. Hence, the
potential availability of unskilled labor is more in this region.
3.14.8 Infrastructure Facilities in the Study Area
Infrastructure is basic physical and organizational structures needed for the
operation of a society or enterprise, or the services and facilities necessary for
an economy to function. It can be generally defined as the set of
interconnected structural elements that provide framework supporting an
entire structure of development. It is an important term for judging a country
or region's development. The term typically refers to the technical structures
that support a society, such educational institutions, medical facilities
banking facilities, telecommunications and so forth, and can be defined as
"the physical components of interrelated systems providing commodities and
services essential to enable, sustain, or enhance societal living conditions.
3.14.9 Drinking Water Facility
Drinking water is the primary need for survival of the men, animal and plant
kingdom. The state spent thousand and thousand Crore rupees to provide
drinking water to the population of the state. Table 3.27 shows that the
region gets drinking water from well, and tube well. It means the water is
directly consumed. No treatment is given to purify the water.

3.15 Primary Socio Economic Survey
3.15.1 Sampling Method
A judgmental and purposive sampling method was used for choosing
respondents of various sections of the society i.e. Sarpanch, adult males and
females, teachers, medical practitioners, businesspersons, agriculture
laborers, fishermen, unemployed group etc. Judgmental and purposive
sampling method includes the right cases from the total population that
helps to fulfill the purpose of research needs.
Data Collection Method
Data collection is a term used to describe a process of preparing and
collecting data, for example, as part of a process improvement or similar
project. The purpose of data collection is to obtain information to keep on
record, to make decisions about important issues, to pass information on to
others. Primarily, data are collected to provide information regarding a
specific topic. Data collection usually takes place early on in an improvement
project, and is often formalized through a data collection plan which often
contains the following activity.
Pre collection activity — agree on goals, target data, definitions, methods
Collection — data collection
Present Findings — usually involves some form of sorting analysis and/or
presentation
Main types of data collection include census, sample survey, and
administrative by-product and each with their respective advantages and
disadvantages. A census refers to data collection about everyone or
everything in a group or population and has advantages, such as accuracy
and detail and disadvantages, such as cost and time.
Types of Data
The data needed for a social science research may be broadly classified into
Data pertaining to human beings,
Data relating to organization,
Data pertaining to territorial.

Field survey involved the collection of primary data or information that was
new. This was collected through surveys and questionnaires that are made
out specifically for this purpose. Observations were conducted on nearly any
subject matter and the kinds of observations were depending on survey
question. Field Survey and Observations were made at each sampling village
and the quality of life of that region was studied. Visits were made at
hospitals, primary health centers and sub-centers to know the health status
of the region. Various governmental organizations such as statistical
department, department of census operations etc. were visited to collect the
population details of that region.
Interview Method
Interview is verbal questioning. Surveys were also conducted through
interviews. Interviews consisted of asking questions, listening to individuals
and recording their responses. At times, it was found that it was more
profitable to ask questions to a few individuals instead of carrying out a
large-scale questionnaire based survey. The interviews were done very
informally e.g. as conversations with people met in the fields,at co-operative
stores or block offices. In these meetings, one question leads to the next based
on the responses given to the previous one. At the other end of the scale,
highly structured interviews often rely on questionnaires or interviews held
with mostly closed-ended questions that allowed the respondents only a
limited range of possible answers. Structured interview method was used to
collect data regarding the awareness and opinions from the sample selected
of the various socio- economic sections of the community. The questionnaire
mainly highlights the parameters of primary needs. The interview method
has the advantage that almost all the perfect sample of the general
population was to be reached and respond to the approach. Interview method
helped to collect more correct and accurate information as the interviewer
was present during the field survey.
Socio-economic survey was conducted in four villages of core zone and 2
villages of buffer zone, within the study area located in all directions with
reference to the project site. The respondents were asked for their
awareness/opinion about the project and their opinion about the impacts of
the project, which is an important aspect of socio-economic environment, viz.

job opportunities, education, health care, transportation facility and economic
status.
According to survey done in the study area, the observations made are as
follows:
In the study area, the main occupation of the villagers is agriculture,
labour work and small business of cutlery items etc.
Most of the houses are in pakka form.
Villages are well connected by tarred roads with the district place
Farmers depend mainly on monsoon for agricultural activities.
Communication facility is good due to better mobile network and
transportation facilities.
All villages are well electrified and use of electricity for all purposes.
Main language in study area is Gujarati & Hindi widely spoken by the
population.
LPG is used by villagers in general, as fuel for cooking; otherwise wood,
kerosene etc.
3.15.2 Awareness and Opinion
Awareness is the state or ability to perceive, to feel, or to be conscious of
events, objects or sensory patterns. In this, level of consciousness, sense data
can be confirmed by an observer without necessarily implying understanding.
In general, an opinion is a subjective belief, and is the result of emotion or
interpretation of facts. An opinion may be supported by an argument,
although people may draw opposing opinions from the same set of facts. For
assessing the awareness and opinion about the project activity, socio-
economic survey was conducted in the sampling villages.
The salient observations drawn through survey are given below:
The respondents from almost all the villages were aware about the project
activity.
Some of the respondents have very good opinion about the project and
they opined that due to proposed project activity, quality of life of the
villages will improve.
Respondent have suggested minimizing the environmental pollution
during and after project activity.

4 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION
MEASURES
Opencast mining activity may cause some impacts on the surrounding
environment unless proper mitigation measures are adopted. Selecting
suitable sites for mining and also adopting all the guidelines prescribed by
the ministry of environment and forest with proper environment
management plan can minimize the major impacts. In this chapter, an
attempt has been made to quantify the possible environmental impacts and
recommend mitigation measures improve the environment and reduce the
impacts to acceptable level.
Any human activity in any environment produces impact or modifying it
to a status which is considered adverse or beneficial according to the
damage or improvement it brings about in physical, chemical and
biological status of air, water, land including bio-diversity, socio-cultural
life styles and economy of the populace it affects. Depending on the
nature of activities and existing status, the impacts are assessed for
their importance. On the basis of the impact analysis, the mitigating
action and future monitoring requirement are focused in the
Environmental Management Plan for counting or minimizing adverse
impacts.
Effects of this mining project on each of the environmental component
are detailed below in accordance with the parameter of environment
likely to be affected. The parameters, which are relevant in the context, are
given below:
Land use
Air quality
Water resources
Water quality
Noise levels and ground vibration
Ecological factors
Socio-economic conditions
Generally, the environmental impacts can be categorized as either primary or
secondary. Primary impacts are those which can be attributed directly to the
project. Secondary impacts are indirect or induced and typically include the
associated investments and change patterns of social and economic by the
proposed actions.

4.1.3 Post Mining Land Use Pattern
At the end of life of mine total 3.7125 hectare area will be excavated, 3.7125
Ha. area will be turned to water reservoir, 0.9875 Ha. will be used for
plantation. All necessary precaution will be taken as per Rule. 106, 115(1) of
MMR,1961.
4.2 Impact on Soil
The leasehold area is Govt. Waste land. The Lime stone mine is an existing
mine. Soil generated due to activities will be stacked on benches separately
and shall be utilized for afforestation. The soil will be mixed with fertilizer
and will be filled in pot holes made for growing plants.
4.3 Impact on Water Quality
4.3.1 Impact on Surface Water Quality
There is no abstraction of surface water. The opencast mining operation usually
causes surface water pollution. The sources of pollution generally are run-off
from mineral reject yard and mining area. The mining area lies on flat land
and has some soil cover, therefore storage of soil is required. However if
some soil is encountered in small patches during mining, then it will be
recovered carefully and used for plantation purpose. There is proposal for
mineral reject yard. There is proposal of utilization of waste material in
construction of parapet walls, retaining walls & check dams and paved roads.
The rest of waste material will be stacked in dump stack as in mining plan.
No water source exists within the lease area and there is no any water body or
spring inside lease area.
4.3.2 Impact on Ground Water Quality
Ground water pollution can take place only if dumps and stockpiles
contain harmful chemical substances that get leached by precipitation of
water and percolate to the ground water table. This is not the case with this
mine; the mining will not intersect with the ground water table. The excavation
of limestone further does not add to any harmful ingredients that could leach
down to the water table. The composition of limestone is mainly CaO and MgO.
Thus the mine workings shall not affect the ground water quality.

4.3.3 Proposed Mitigation Measures
Adequate control measures will be adopted to check not only the wash-off
from soil erosion but also uncontrolled flow of mine water. The measures to
be adopted are:
The ground water table (15mRL) thus shall not be encountered nor shall
groundwater regime be affected. Further as per secondary data on
hydrogeology, these areas are underlain by semi-consolidated and
consolidated hard rock‘s.
Garland drains will be constructed on all side of quarries and external
dumps. All the garland drains will be routed through settling pits to remove
suspended solids from flowing into storm water. The water collected in the
pit, after settling of the suspensions, shall be used for plantation.
Retaining walls with weep holes should be built all round the dumps. The
storm water should pass through weep holes to the garland drains as
detailed out in mining plan.
A temporary toilet with septic tank shall be provided at the site for the use of
workers during day time to prevent toilet in open.
4.4 Impact on Air Quality
4.4.1 Impact during Construction Phase
There will be no impacts on ambient air quality as no construction stage is
involved in this project.
4.4.2 Impact during Operation Phase
The major impact on ambient air quality in opencast mining is due to dust
generation by various mining activities especially due to movement of
dumpers / trucks on haul roads. The other activities which are responsible for
dust generation are drilling and blasting in ore benches, loading and
unloading of overburden, soil and stone, operation of equipment at mining
site viz. excavator, jackhammer, shovel etc. However, the dust generation due
to these activities is for short duration and localized in nature. Other

atmospheric pollutants viz. SO2 and NO2 are not expected to have
considerable variation due to mining activities of proposed project. As the
dust generation from mine haul road is the major contributor towards
deterioration of air quality, Air Quality Modeling for PM10 emission from
haul road is carried out using ISCST3 to assess the severity of impact.
Emission Characteristics for Mining Operations
Dust emission rate from the Mining area, based on the following empirical
formula.
a) Dust emission due to excavation:
Pa x 23.6
Dust emission (DE) = ----------------------
Wd x Wh x 1000
DE = Dust emission in kg/hr
Pa = Annual Excavation in Tonnes
Wd = No. of days of operation in a year
Wh = Effective working hrs in a day
23.6 Quantity of dust emitted in kg/for 1000 tonnes of excavation
Dust emission rate=16890 x23.6)/ 300x8x1000)= 0.1661 kg/hr
The above mentioned emission rate is without adoption of dust control
measures. The literature suggests that dust control measures reduce the
emissions and effective emission rate is one third of the computed emission.
Accordingly emission rate to be in the modeling is (0.1661 /3) i.e. 0.0554
kg/hr.

Meteorological Data
On site hourly meteorological data for Summer (March to May2017) in
respect of wind speed, wind direction, temperature and cloud amount are
utilized in this study. The data was put in model format. The mixing heights
have been extracted from CPCB publications.
Modeling Procedure
Methodology:
Prediction of ground level concentrations (glc‘s) due to mining have been
made by Industrial Source Complex, Short Term (ISCST3) as per CPCB
guidelines. ISCST3 is US-EPA approved model to predict the air quality. The
model uses rural dispersion and regulatory defaults options as per guidelines
on air quality models (PROBES/70/1997-1998). The model assumes receptors
on undulating and hilly. This model is capable of handling point, area, and
line sources simultaneously.
Meteorological inputs required are hourly wind speed and direction ambient
temperature, stability class, mixing height and wind exponents. The model
details follow.

4.6.1 Impact on Wildlife
There is no National Park, Wildlife Sanctuary, and Biosphere Reserve,
Wildlife Corridors, Tiger/Elephant Reserves etc. within 10 km radius of the
project site.
Therefore mining will not cause a problem to the existing wildlife.
It is also observed that the faunal species found in the study area are
commonly found species. No rare, endemic & endangered species are reported
in the core / buffer zone. However, during mining activities the mine
management will practice scientific method of mining with proper
Environmental Management Plan including pollution control measures
especially for air and noise, which will not cause any adverse impact on the
surrounding wildlife.
Besides, Plantation & Green belt development will be undertaken to improve
the floral cover of the area which will eventually attract micro fauna, birds
etc. in the area thereby help in development of wildlife. For that, assistance
will be taken from local forest department in selection of species of plants so
that green coverage could improve very fast. The varieties that will be
planted would include those plants, which are suitable to the area.

5 ANALYSIS OF ALTERNATIVES
5.1 Analysis of Alternate Site
Kodidra mine of lime stone is situated at village- Kodidra, Tehsil- Veraval,
District-Gir Somnath, Gujarat. Mining of Lime Stone is site specific activity.
The mine is to be located where the mineral exists in sufficient quantity to be
economically extracted. The site selected has following advantages:
1. The area chosen for mining activities is not having habitation of any kind.
2. There are some other Lime stone mines in the study area, hence basic
infrastructure such as road and electric connection are available.
3. Better availability of experienced labors from nearby villages.
4. No endangered species around the mine site.
5.2 Analysis of Alternate Technology
The mining techniques have transformed dramatically since it began
thousands of years ago. With the development of new technologies, many
advanced methods have been adopted. It yields more extraction and least
environmental impacts. That commitment involves an intense drive to
improve the safety and health of workers and lifting the economic and
environmental performance of mining operations. Mining methods are
constantly changing and improving as companies forge new technologies to
enhance rates of extraction and minimize impacts such as noise, dust, land
and water disturbance. The mining methods used are (i) open-cast and (ii)
underground.
5.2.1 Open- Cast Mining
Open-cast mining known as surface mining is most effective when the
mineral deposit is close to the surface. The mining process is fundamentally
different between the soft-rock and hard-rock operations. The techniques
involves with (or) without blasting depending on the hardness of the rock and
removing surface layers of soil and other rocks to reach the deposit. In some
cases, a separation process will be used to eliminate waste by-products. It has
maximum recovery of mineral compared to underground method of mining.

5.2.2 Underground Mining
There are several variations of underground mining. The common factor for
all forms of underground mining is the creation of tunnels extending from the
surface into the mineral seam/lode and the use of machinery to extract the
mineral. The most commonly used under- ground mining methods are
stopping methods, board &pillar, long wall, caving methods, cut & fill and
retreat benching etc. Lime Stone mining is soft material hence underground
mining methods are not suitable.
5.2.3 Selection of Mining Technology
After the complete analysis of various technologies, the nature of material to
be excavated that are in practice, it is proposed to operate the mine by
manual opencast method by using light weight excavators for loading of
mineral in tippers and dumpers, as Lime Stone deposits are close to the
surface. No other alternative technologies can be used because of the soft
nature of the Lime Stone mineral. M/s GHCL Limited will use eco-friendly
measures to minimize the impact on the surrounding environment.
5.3 Details of Mining Methodology
Mining is proposed to be carried out by opencast manual method of mining by
forming benches of 1.5m height. Drilling of 32 mm dia. holes with burden and
spacing of 1 & 1.2 m respectively. Loading of blasted rock is proposed to be done
by excavator having 0.93 cu.m. Bucket capacity. Existing approach roads will
continue to be used and gradient of not less than 1:16 will be maintained. The
ultimate depth of the mine workings is estimated to be well above the ground
water table.
The salient features of proposed mining technique are:-
The height of the bench will be maintained at 1.5 m.
Width of the benches is maintained more than height of the bench
The mining will be done from top to bottom.
Considering the stability of rocks, the final slope or say ultimate pit slope
is proposed 45° from vertical.
The haul road will be developed up to the point of loading and will not
have gradient 1:16.
The transportation of the mineral from mine to end users will be done by
hired trucks.

6 ENVIRONMENTAL MONITORING PROGRAM
6.1 Introduction
The industrial development of any area needs to be intertwined with
judicious utilization of non-renewable resources of the study area and within
the limits of permissible assimilative capacity. The assimilative capacity of
the study area is the maximum amount of pollution load that can be
discharged into the environment without affecting the designated use and is
being governed by dilution, dispersion and removal due to physicochemical
and biological processes. The Environment Monitoring Programme has been
done to ensure sustainable development in the study area (10 km) of the
project site and to monitor the pollution levels due to the proposed activities.
6.2 Monitoring Schedule and Parameters
To evaluate the effectiveness of environmental management programme,
regular monitoring of the important environmental parameters will be taken
up. The schedule, duration and parameters to be monitored are shown in
Table 6-1.

10.2 Conclusion
As discussed, it is safe to say that the collection of minor mineral from the
proposed lease area is not likely to cause any significant impact on the
ecology of the area as the mineral is replenish able naturally and does not
harm the surrounding environment.
Adequate measures will be taken to control the fugitive emissions to be
generating during mining operation. Green belt development in the vicinity
of river banks, approach roads, Govt. buildings, Schools also proposed with
the help of local govt. department and local people as social forestry in the
area for betterment of environment.
