report, within the overall framework of the prescribed ToR:

To Describe and Assess

1. The prevailing baseline environmental and socio-economic condition of the

study area through baseline studies and secondary data collection

2. The proposed project (i.e. mining) methodology, including equipment,

procedures and processes, based on interactions with project owners /

managers, and information presented in the approved mining plan

To Determine

1. Impacts of the project on the environment, ecology, workers and

community, due to the proposed project

2. Formulation of Mitigation measures for the impacts identified

3. Alternatives in terms of project concept and location, mining methods,

To Recommend

1. An Environmental Management Plan (EMP) with action plans and a

management system covering timing, responsibilities and costs and

considering the existing regulatory framework, for implementing the

selected alternatives and mitigation measures covering: water use and

quality, wastes, hazardous materials, land use and bio-diversity, air

quality, noise and vibration, and visual impacts, as also remedial

measures when deviations occur.

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




25



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.

2.3 Geology

Topography – The configuration of the area is irregular polygon shape and

elongated along N-S direction. The Lease area is part of coastal Arabian and

away from the central direction. The lease area is part of coastal Arabian Sea

and away from the central highland of Gir. The area present the gently

undulating to semi flat. The area is surrounded by private agricultural fields.

The soil occurrence in thin layer close to the boundary. The highest surface

RL of the area is at 50 mRL in the NE portion near boundary line and lowest

surface is at 49 mRL in the western portion eastern portion.

2.3.1 Regional Geology

The sedimentary limestone is the most common and important rock type

exposed in the coastal belt of Saurashtra region. The Northen land mass

bears Igneous Deccan Trap rocks and Intrusive. Stratigraphy of Saurashtra

region in Gujarat is as follow:

Regional Rock Type:-

The Deccan trap of upper Cretaceous age covers entire Saurashtra region.

The Sedimentary rocks (limestone) are outer fringes bordering Arabian Sea.

Kodidra limestone deposit is a part of Porbandar limestone of Pleistocene Age

occurring along coastal belt of Veraval region. The limestone deposition of the

coastal area begin from few km to 40 km towards in and often extending

more depending upon the pale geographically condition as in the case of

miliotic limestone up to Rajkot and even Drangadra in Surendranagar

District. Along the coast, the limestone deposition occurs from Dwarka to

Bhavnagar via, Porbandar, Mangrol, Una, Jafrabad, Talaja and Mahuwa.




47



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.

Physical & Chemical properties:

Colour : White buff to light brown

Streak : White to creamish white

Luster : Earthy

Cleavage: Nil




48



The limestones of this deposit are of two types, i.e. chemical grade and

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:

Table 2-3: Litho units of Study Area

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.

3.4.2 Land Use Pattern of Mining Lease (Core Area)

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

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.




85



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 unconfined -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)




90



-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




91



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.




92



(i) Ground Water Utilization

Irrigation and domestic consumption are two main modes of utilization of

ground water in the area. The present utilization of ground water for

irrigation purpose is through dug wells with bullock and motes and wells

fitted with pumps operated by electric motors and diesel pumps.

( j) The water Balance Chart:

The mining operations do not require water. Quality of water required for

sprinkling on the haul road, watering the planted area and for humans

consumption for the work – force employed at the area is about 10 to 15 cu. m

per day. The required quantity of water of water will be available from the

bore hole located near existing office.

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




108



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.

Mitigation Measures s

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




109



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

NE.

3.14.7 Literacy Details

Literacy Rate is the amount of people in a country with the ability to read

and write. The analysis of the literacy levels is done in the study area.

Literacy in any region is key for socio-economic progress and the Indian

literacy rate grew to 74.04% in 2011 from 12% at the end of British rule in

1947. Although this was a greater than six fold improvement, the level is well

below the world average literacy rate of 84% and of all nations, Table and

gives the educational status of the study area.

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 and Observations




115



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.




116



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.





MITIGATION MEASURES

4.1 Impact on Land Environment

4.1.1 Impact on Land Degradation

Total 4.70 ha of mine lease area Govt. waste land. The proposed lime stone

mine is an existing mine. Since the land degradation is restricted only to the

mining area and the area within the mine lease boundary, the reclamation

strategy must include the programme to reclaim the disturbed land. No

adverse impact is anticipated on land.

4.1.2 Mitigation Measure for Land Degradation

Total 3.1725 hectare area will be turned to water reservoir & 0.98715 hectare

area will be use for plantation present land use, land use after 4 years

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.





MITIGATION MEASURES

120



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





MITIGATION MEASURES

121



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.

Mine Dimensions

The mine dimensions are as follows:

Area = 4.70hectare

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.

4.4.3 Mitigation Measures

The proposed mining operations are not anticipated to raise the

concentration of the pollutants beyond prescribed limits. However, the

following measures are suggested mitigate any harmful impacts of pollutants

-

Plantation of trees along haul roads, specially near settlements, to help to

reduce the impact of dust on the nearby villages;

Planning transportation routes of mined material so as to reach the

nearest paved roads by shortest route. (minimize transportation over

unpaved road);

Dust mask shall be provided to the workers engaged at dust generation

points like excavations and loading points;

Regular water sprinkling on unpaved roads to avoid dust generation

during transportation;

Transportation of material shall be carried out during day time only;

The speed of trucks plying on the haul road should limited to avoid

generation of dust;

Haul road shall be covered with gravels; and

Covering of material during transportation on trucks to prevent spillage of

sand from the trucks. The trucks shall be covered by tarpaulin.

Overloading shall be avoided.

4.5 Impact of Noise/ Vibration

4.5.1 Impact of Noise

The area in general represents calm surroundings. There is no habitation

around and the nearest village is about 1.5 Km away.

The main source of noise pollution and vibrations are (i) movement of trucks (ii)

Operation of excavator (iii) Drilling of holes for blasting and (iv) Blasting itself.

4.5.2 Mitigating Measure for Noise:

There is no habitation in immediate vicinity. The nearest population is in

village Kodidra at about 1.20 km from the mining site. Continuous noise levels

beyond the prescribed standards can, however, have impact, on fauna. These

can also have an impact on workers.





MITIGATION MEASURES

127



The following control measures are been adopted to keep the ambient noise

levels well below the limits at the mine boundary:

Plantation shall be carried out along mining lease boundary and sides of

haul roads, etc. The greenbelt minimizes propagation of noise.

Proper maintenance of vehicles shall be done.

Mine operations shall be limited to day time i.e 9AM to 6 PM

Power Horns shall not be allowed in trucks. Drivers shall be further

instructed not to use music systems at high volumes.

The compressor used for drilling holes shall be provided with proper

enclosures.

The blasting is of low impact type with a maximum impact area of 500 m

The excavator use will be for limited hours with breaks at regular intervals.

The driver is provided with ear plugs. The excavator will be regularly

serviced.

By carefully designing a blast hole using experience and deciding drilling

pattern or blast geometry with appropriate burden distance, spacing as

holes, hole size, hole depth, and stemming height, and powder factor.

In order to reduce the effect of noise pollution, ear plugs /earmuffs shall be

provided to workers

Ambient and Source Noise level Monitoring will be conducted on regular

basis to assess the quality of ambient air w.r.t noise as per the proposed

monitoring plan.

4.5.3 Mitigating Measure forVibration

The nature of mining activity is such that vibration cannot be eliminated. But

the vibration can be checked prevented. In lease area there is no building which

is likely to be affected by vibration. Control of ground movement due to

vibration can be achieved by avoiding over charging, by use of delays and

4.6 Impact on Biological Environment

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.

4.6.2 Mitigation Measures for Flora

Green Belt Development

The sapling for plantation will be selected on basis of water availability of

water & according to climatic condition and hence it is proposed to plant 386

saplings per year. The plantation will be done along the lease boundary.

Year- wise program of green belt development for four years is given below.

About 386 saplings will be planted in an area of 0.9875 ha upto the end of 4

years. By the green development it will improve the eco-systems and

aesthetic beauty of the area. Post plantation cares including provision for

watering, soil mulching manure supply to plants will be done.

This will help in reducing the spread of pollutants and will also be effective in

attenuating noise levels.

environment.

Greenery development around mine area will help in creating habitats for

local faunal species and to create better environment for various fauna.

Creating and developing awareness for nature and wildlife in the

adjoining villages.

4.7 Socio economic Environment

The mining activities in the proposed area will definitely help in the

improvement of socio-economic status of the people around the mine area by

generating direct or indirect employment opportunities. The project will also

attract ancillary and related small-scale industries in the adjoining areas.

Continued mining activities will benefit the local people due to provision of

more infrastructural facilities provided by local industry as mining industry

will boost up the local market.

Since, the extraction of the reserves of this mineral is economically viable,

their proper utilization will improve the economic status of the people nearby

and the country as a whole.

The social welfare activities will be handled by a full time team of village

development officials, who will monitor the programme and give necessary

back-up support. The programs will be made broad based by involvement of

local groups and government agencies to the maximum extent possible.

4.7.1 Measure to Improve Socio Economic Status

With mining activities, local people will have a lot of direct and indirect

employment avenues opened up. There will be direct employment

opportunities in the mine and also the secondary employment by providing

services to the employed manpower. Thus the local people will enjoy the

economic upliftment. The following activities will be followed: -

Rural/village & Community welfare,

Thus the socio-economic status of the area will be improved.

4.8 Occupational Health and Safety

Occupational health and safety (OHS) is a cross-disciplinary area concerned

with protecting the safety, health and welfare of people engaged in work or

employment. The goal of all occupational health and safety programs is to

foster a safe work environment.

Occupational health hazards at mine site:

Mining activity experiences risk of a number of hazards. Some examples of

such hazards are as under:

Exposure to dust

Noise exposure;

Physical Hazards;

Vehicular movements and related accidents.

These mainly impact on those working within the mine although health

hazards can also impact on local communities. Therefore, protective

measures are required for health and safety of the employed persons. The

health of workers and the persons around the lease area will be regularly

monitored. All the personal protective equipment‘s will be provided to

employed persons. The mining in the area will be got done with all safety

measures.

Implementation of Occupational health and safety measures:

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.



TEHSIL VERAVAL, GIR SOMNATH DISTRICT OF GUJARAT ANALYSIS OF ALTERNATIVES

135



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 underground 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

dangers or risk which needs to be investigated and addressed. Disaster

management plan is formulated with an aim of taking precautionary steps to

avert disaster and also to take such action after the disaster which limits the

damage to the minimum.

Nevertheless, the following natural/industrial problems may be encountered

during the mining operation:

Inundation-Filling of the mine pit due to excessive rains/flooding.

Slope failures at the mine faces.

Accident due to fire.

As per proposal made under the Mining Plan, during proposed working, the

area will be developed by means of opencast mining method. Exploitation and

transportation of mineral are to be carried out by semi-mechanized means.

Ultimate quarry depth will be 8 m below the surface level. Bench height is

kept 1.5 m. Ground water table in this region of 15- 20 m from the surface.

Mining will not intersect the ground water level. But possibility of accidental

disaster is also not ruled out. Therefore, all the statutory precautions should

be taken for quick evacuation as per the Mines Act 1952, the Mines Rules

1955, Rule of MMR- 1961 and the Rules of MCDR-1988.

7.3 Anticipated Disaster and Corrective Actions

7.3.1 Inundation

This is Lime Stone mine project. In case of inundation, at any time in the

future, the water will be allowed to stand and naturally percolate into the

ground. If there is any need to empty out any particular pit for working, then

pumps will be used to pump out the water. In other cases where possibility of

accumulation of water is there preventative & management measures shall

be planned as per Regulation of MMR 1961.

7.3.2 Disaster Due to Failure of Slope

The pit slopes may fall at any time causing damage to human life and

machinery. The only remedy to the effect of such situation is to dress pit

slopes and maintaining the pit slope as specified in Metalliferrous Mine

Regulations, 1961.

7.3.3 Disaster Due to Fire

No surface fire is involved in Lime Stone mining. The lease area does not

involve forest area/land.

The EIA study for the proposed project has identified impacts that are likely

to arise during different phases of the project. The study has also examined

the extent to which the adverse impacts identified can be controlled through

the adoption of mitigation measures. The Environment Management Plan

describes both generic good practice measures and site-specific measures, the

implementation of which is aimed at mitigating potential impacts associated

with the proposed activities.

9.1.2 Purpose of EMP

The environment management plan is prepared with a view to facilitate

effective environmental management of the project, in general and

implementation of the mitigation measures in particular. The EMP provides

a delivery mechanism to address potential adverse impacts and to introduce

standards of good practice to be adopted for all project works. For each stage

of the programme, the EMP lists all the requirements to ensure effective

mitigation of every potential biophysical and socio-economic impact identified

in the EIA. For each impact or operation, which could otherwise give rise to

impact, the following information is presented:

A comprehensive listing of the mitigation measures to be implement

The parameters that will be monitored to ensure effective implementation

of the action

The timings for implementation of the action are also included to ensure the

objectives of mitigation get fully met. The EMP is presented in Table.9.1
