3.2 Ambient Air Quality:

To assess the ambient air quality level, 7 monitoring stations were set up. Ambient air quality

monitoring was carried out twice a week with a frequency of 24 hours for 12 weeks. The results

when compared with National Ambient Air Quality Standards (NAAQS) of Central

Pollution Control Board (CPCB) for "Residential and Rural Areas" show that the average values

of ambient air quality parameters are well within the stipulated limit.

The minimum and maximum concentration of PM10 recorded within the study area was 50.5µg/m3 to 139.4 µg/m3 with the 98th percentile ranging between 63.3 µg/m3 to 130.7 µg/m3.

The minimum and maximum concentration of SO2 recorded within the study area was <5 to 6.8µg/m3 with the 98th percentile ranging between 6.2 µg/m3 to 6.8 µg/m3.

The minimum and maximum concentration of NOx recorded within the study area was 6.5µg/m3 to 15.3 µg/m3 with the 98th percentile ranging between 12.7 µg/m3 to 15.1 µg/m3.

3.3 Noise Levels:

The values of noise observed in some of the areas are primarily owing to vehicular traffic andother anthropogenic activities. Assessment of night time Leq (Ln) varies from 38.1 to 54.6 dB(A) and the daytime Leq (Ld) varies from 46.3 to 68.4 dB (A) within the study area. The status ofnoise quality within the 10 km zone of the study area is, therefore, within the MoEF standards.

3.4 Water Quality:

Selected water quality parameters for water resource of the study area have been used for

describing the water environment and assessing the impacts. Seven ground water samples

were collected in the study area to assess the water quality. Water samples were also drawn

from the hand pumps and open wells and two surface water samples were drawn from the

natural springs being used by the villagers for domestic needs. For surface water quality,

comparing the values of pH, DO, BOD and total coliforms with ‘Use based classification of

surface waters’ published by Central Pollution Control Board; it can be seen that all the

analyzed surface waters can be compared with class “C” and can be used as drinking water

sources after conventional treatment and disinfection.

8


3.5 Soil Characteristics:

The soil samples were collected in the month of May 2015. Soil samples were collected from 7

locations to assess the existing soil conditions representing various land use conditions and

geological features. Each of these locations was identified randomly. Soil sample was collected

from 30 cm below the surface. pH of the soil were found to be Neutral (7.46 to 7.86 ). Electrical

conductivity (EC) is a measure of the soluble salts and ionic activity in the soil, and ranged from

241‐432 µmhos/cm.

3.6 Biological Environment:There are few forest patches and reserved and protected forests in study area. Marine National

Park/Marine Sanctuary is present within 5 Km of the study area. Conservation plan of Schedule

–I species found in study and has been prepared.

3.7 Socio economic environment

The impact of mining activity in the area is positive on the socio-economic environment of the

region. Virpur (Gunawali) Bauxite Mine is providing employment to local population and

preference will be given to the local people for man power.

4.0 Post Project Monitoring Program

5.0 Additional Studies:

The Additional Studies conducted are Risk Assessment & Disaster Management / Hazard

Management & Occupational Health & Safety.

5.1 Risk Assessment and Disaster Management Plan

The complete mining operation will be carried out under the management control and

direction of a qualified mine manager with Certificate of competency to manage a

metalliferous mine granted by the Directorate General of Mines Safety (DGMS),

Dhanbad. The DGMS have been regularly issuing standing orders, model standing orders

and circulars to be followed by the mine management in case of disaster, if any.

Moreover, mining staff will be sent to refresher courses from time to time to keep them

alert.

5.2 Disaster Management Plan

Emergency preparedness is an important aspect in the planning of Disaster

Management. Personnel would be trained suitably and prepared mentally and physically

in emergency response through carefully planned, simulated procedures. Similarly, the

key personnel and essential personnel shall be trained in the operations.

6.0 PUBLIC CONSULTATION

6.1 Public Hearing

The draft EIA is prepared and submitted to Pollution Control Board for Public Hearing. Thepublic hearing for the Virpur (Gunawali) Bauxite mine for 1, 51,875 TPA capacities by semimechanized open cast method in Virpur (Gunawali) village, Kalyanpur Taluka, DevbhumiDwarka District, Gujarat was conducted on 29.03.2016, as per the Environment ImpactAssessment Notification dated 14th September 2006. The public hearing proceedings &related papers are attached as Annexure- XIII.

7.0 Project Benefits:

The project will prove beneficial to the people as the lessee has already agreed to provide

infrastructural facilities to the villagers like Educational facilities, Medical facilities,

10


Transportation facilities, water supply etc. which will improve the socio-economic environment

of the area.

8.0 Environmental Management Plan

The mining activities involve, dozing, excavation, loading, haulage and transportation of mined

minerals. These activities lead to generation of air borne dust, which can cause air pollution in

and around the mining lease area, if appropriate control measures are not taken. Similarly mining

causes Land Degradation, Noise and Water Pollution etc. in the area.

In order to minimize impacts of mining on different environmental parameters and to keep air

and water quality within prescribed limits of CPCB, a rapid Environmental Management Plan

(EMP) is prepared to strictly follow it. This helps in resolving all environmental and ecological

issues due to mining in the area. The environmental management plan includes all measures and

safety precautions necessary for safe mining along with rehabilitation measures for mined out

areas

8.1 Green Belt/Plantation

0.2000 ha area will be developed under as green belt.

8.3 Conclusion

Based on the EIA study it is observed that there will be generate minor dust emission, which will

be controlled by sprinkling of water and plantation. There will be an insignificant impact on

ambient environment and ecology due to the mining activities moreover the mining operation

will lead to direct and indirect employment generation in the area. Green belt development

around the area will also be taken up as an effective pollution mitigative technique, as well as to

control the pollutants released from the premises of the Mine.

Monitoring program will be followed till the mining operations continue. Around Rs 1.75 lakhs

as capital cost and Rs 1.8 lakhs as recurring budget for environmental protection have been

formulated to achieve the environmental quality as desired. Hence, it can be summarized that the

development of the mine will have a positive impact on the socio-economic of the area and lead

to sustainable development of the region.

The study area is still lacking in education, health, housing, water, electricity etc. It is expected

that same will improve to a great extent due to proposed mining project and associated industrial

and business activities. Proposed activities and expenses on Corporate Social Responsibility will

be as per CSR Mandate of the Government.

1.3.5 Importance to the Country & Region

Bauxite is a mineral found mostly in a belt around the equator. Bauxite, containing

15-25 percent aluminium, is the only ore that is used for commercial extraction of

aluminium today. It is extremely important economically due to the very widespread

use of aluminum. It is used in almost everything from soda cans to candy wrappers

to cars, aircraft, and boats. It is the most common light weight metal in use.

Resources of bauxite in the country as on 1.4.2010, as per UNFC system, are placed

at 3,480 million tonnes. These resources include 593 million tonnes reserves and

2,887 million tonnes remaining resources. By grades, about 84% resources are of

metallurgical grade. The resources of refractory and chemical grades are limited and

together account for about 4%. By States, Odisha alone accounts for 52% of

country's resources of bauxite followed by Andhra Pradesh (18%), Gujarat (7%),

Chhattisgarh and Maharashtra (5% each) and Madhya Pradesh and Gujarat (4%

each). Major bauxite resources are concentrated in the East Coast bauxite deposits

in Odisha and Andhra Pradesh. (Source: Indian Minerals Yearbook 2013, Part II

http://ibm.nic.in/IMYB%202011_Bauxite.pdf).

1.3.6 Supply and Demand Details

The production of bauxite in India, at 15,360 thousand tonnes in 2012-13 increased

by 11% as compared to the previous year due to better market demand. There were

152 reporting mines in 2012-13 as against 172 in the previous year. Besides,

production of bauxite was reported as associate mineral by 10 mines during the

year. In all, 70 producers reported production of bauxite in 2012-13. Ten principal

producers having 42 mines contributed 86% of the total production. Forty seven

major mines, each producing more than 50 thousand tonnes per annum, together

accounted for 93% of the total production. The share of 18 public sector mines was

about 42% of the total production in 2012-13 as against 43% contributed in the

previous year. About 63% of the total production of bauxite was of 40-45% Al2O3

grade, 15% was of cement grade, 12% was of 45-50% Al2O3 grade, 7% was of below

40% Al2O3 grade, 2% was of Refractory grade, and 1% of production was reported


I-12

together in 50-55% Al2O3, 55-60% Al2O3 Abrasive and Chemical grade during the

year under review. Odisha continued to be the leading producing state accounting

for about 38% production. Next in the order of production were Chhattisgarh and

Maharashtra (13 % each), Gujarat (20%), Jharkhand & Maharashtra (13%) and

Madhya Pradesh 5%. The remaining two percent was produced by Goa, Karnataka

and Tamil Nadu. In 2012-13, reported consumption of bauxite in India was 11.02

million tonnes as compared to 10.37 million tonnes in the previous year.

Alumina/aluminium industry was the principal consumer of bauxite, accounting for

88% consumption in 2012-13 followed by cement (9%) and refractory (2%). (Source:

2.6 Physiography

The leasehold area is covered by soil in peneplained terrain without any major

topographical relief. The mining lease area is government waste land. The lease area is in

irregular shape. Bauxite can be seen in working pits in all the blocks. No cultivation is being

done in leasehold area. Bajra and jawar are MC main crops of the region, which are grown

on the cultivable land outside mine lease in the area.

There is no river or nala crossing in the lease area. The rainy water follows the natural slope

of the area. In general the area is having slope in eastern direction. Rainy water of region

ultimately goes into Arabian Sea. However in general water flow in eastern direction. The

temperature reaches up to 450C during summer and minimum up to 120C in the winter. The

average rainfall of the region is 400 mm per year. Except small bushes no tree can be seen in

the area. There is no reserve or protected forest in the area. There is no village within lease

area. The nearest village is Virpur, Mewasa & Kenedy.

2.7.2 Details of Exploration: -

In the proposed mining, the Mining work will be carried out from southern part of the leasearea during modified mining plan period in one shift only.Soil will be first scraped/excavated and stacked near pit temporary. It will be spread overstatutory barrier. Bauxite present in the area with a thickness of 4.5 will be mined out byforming one bench of 4.5m each with the help of excavator- tipper combination. Initially abox cut is made for formation of RAMP with 1:16 in gradient to reach the pit bottom of the


II-9

one bench. The bauxite will be transported to porbandar by hired truck. The existing fairweathered road will be used as approach road to connect village.

Geometry of bench:-The height of bench will be 4.5m and the width of benches will be 10m and slope of benchwill be maintained 700 from vertical.In the next five years the mining will be done by semi mechanized open cast method (OTFM)by using excavator and tippers. The width of bench will be kept 10m and height of benchwill be of 4.5m. The blasted bauxite will be sorted manually on pit surface. The slope of theface will be maintained 700 from vertical during mining operation.In general bauxite of the area is soft in nature & major part of it can be excavated withoutuse of drilling & blasting. However Drilling will be done in hard compact part of bauxite bed.Drilling will be carried out with the help jack hammer. Blasting will be done by qualifiedblaster under supervision of mining mate / Mines Manger. All precaution as will be takenduring blasting operation.Based on experience gain from the lease area in past, recovery of bauxite from ROM is 95%,rest 5% in waste. Bauxite of the area is of low grade category. The waste generated duringmodified mining plan period will be stacked at pit floor.The bench wise reserves are calculating as under:-

BL x BW x BH x Sp. Gr. x RF = R (T)BL = Bench length in MeterBW = Bench width in MeterBH = Bench height in MeterSp. Gr. = Specific GravityR (T) = Reserves in tones

2.7.3 Indicate Year wise tentative Excavation in cubic meters indicating development,ROM, pit wise as in table below: -As mining lease is having working pits, in the proposed mining plan no development work isproposed. During the proposed mining plan period bauxite will be excavated after removalof soil, for tonnage calculation specific gravity is considered as 2.5 MT/M3. During planperiod work will be carried out in south part of the area.The recovery factor of bauxites from Rom is considered as 0.95 (95% for ROM because lowgrade bauxite upto 35% (Al2O3) will be used & sold as non plant grade (Low grade).During the modified mining plan period, the bauxite mineral left out in working pit will alsobe excavated. The total area (other than already mined out area) of each year to be minedin next four year will be as under:

2.7.4 Year wise production for the ensuring four year of modified mining plan period:-In the proposed mining plan. The mining will be started in south part of lease area. It isproposed to undertake mining work systematically, so as to improve effective supervision,better quality & economic work of the mines. As mentioned above overburden is consistingof soil. Bauxite horizon occurs 0.4m thin cover of soil. Bauxite mineral will be excavated byforming single bench of 4.5m height as the thickness of bauxite zone is 4.5m. The width ofbench will be kept 10k. Drilling & Blasting will be done for bauxite only if required.It is proposed during modified mining plan period; the soil will be scraped & stackedtemporally near pit/ statuary boundary. No bench of soil/ OB will be formed. Bauxitespresent in the area is about 4.5m thick & will be excavated by forming one bench of 4.5 mheight. The width of bench will be kept as 10m minimum.Initially a box cut is made for formation of RAMP with 1:16 gradient to reach pit bottom ofthe ROM bench. The bauxite present in the area is low grade. The recovery of saleablebauxite is 95% of ROM. The 5% of ROM will be generated as waste. The waste generatedduring modified mining plan will be stacked at pit floor.

The past experience of mining activity in the ML as the details of maturity of voids aftermining marked out in the present mining plan have shown that the voids created by miningwill be much larger and the waste rocks and soil left out will be insufficient for backfillingpurpose. Therefore complete backfilling of the mined out area upto original ground level isnot possible. Therefore the mined out will be used as water reservoir as shown inconceptual plan. In the water reservoir the higher benches of excavated mining pit shall beterraced and plantation will be done for stabilizing the slope. The slope of higher bencheswill be made gradual & gentle for easy accessibility by local people to pond water andfencing will be carried out around the water reservoir as required.The waste generated (5% of ROM) will be stacked at pit floor in systematic manner afterexcavation of fall thickness of bauxite.

2.10.2 (B) Afforestation programme upto end of conceptual mining plan period: -It is proposed to undertake plantation programme in the lease area. Plantation work will becarried out along statutory barrier and on backfilled area so that a green belt can bedeveloped. 150 saplings will be planted during modified mining plan period and upto life ofthe mined and 750 plants will be upto life of the mine.

2.11 Post mining land use:-Part of the area will be backfilled and other part of the area will be used as water reservoir.The basic requirement of local community is storage of rain water therefore the mined outarea will be used as water reservoir. In the water reservoir the higher benches on theexcavated pit shall be terraced and plantation will be done for stabilization the slope. Theslope of higher benches will be made gradual and gentle for easy accessibility by localpeople to pond water and fencing will be carried out around the water reservoir.

2.12 Generation of Waste(a) Nature and quantity of top soil, overburden/ waste and mineral reject:

In the proposed mining plan topsoil will be generated but no OB will be generatedthe 5% ROM will be generated as mineral waste.


II-21

The waste that is likely to be generated will be in the form of associated clay with thebauxite horizon as mineral reject, which is below the threshold grade, and has nosale value & of no use. Hence considered as a waste.The yearly rate of generation of the waste has been described in detail in the miningchapter and the date given there is presented in a tabular from below. For the soiland waste the expansion factor considered is 1.3.Top soil will be generated during modified mining plan period.A tabular statement shoeing volume of soil, OB mineralized waste:-

Waste generated during production of mineral bauxite will be stacked in pit floorafter excavation of bauxite upto full thickness. Top soil will be spread over statuarybarrier for plantation.(b) Proposed dumping area: -In the proposed modified mining plan. It is proposed that waste generated duringmining plan period will be stacked at pit floor after excavation of bauxite. Soil will bespread over statuary area for plantation. Part of mined out land will be used as waterreservoir.(c) Disposal of waste, configuration & sequence of year wise build up of dumps &protective measures:-No Backfilling will be done in the area after complete extraction of full thickness ofbauxite. The waste generated during modified mining plan period will be stacked inthe pit floor. As volume of voids (area to be worked) is much more than materialavailable for backfilling, entire mined out area up to original ground level will notpossible. Therefore mined out lease area will be used as water reservoir. Fencing willbe carried out around the water reservoir.

2.17 Characteristics of Ore


II-26

Bauxite is one of the most important industrial minerals and it being the aluminum ore, is

the principal raw material for the production of alumina. Bauxite is formed by lateralization

of various silicate rocks such as granite, gneiss, basalt, syenite and shale. The bauxite rock

usually includes other materials such as iron hydroxides, clay, silt and free silica. It most

often occurs as a residual soil material in tropical and subtropical areas. It is the primary

source of aluminum.

2.18 Use of Mineral

a. End use industry (Physical & Chemical Composition):-i. End use of mineral:The bauxite produced in the mining lease falls under low category only.The low grade category of bauxite is used in the manufactures of cement and which isexported to Middle East countries.

Physical specification for abrasives and ceramic grade bauxite: -The bauxite to be used in the abrasive grains manufactures and in the manufacture of HighAlumina refractory bricks should be in lump form and the size of the lumps should not beless than 10 cm.Physical specification for cement grade bauxite: -In the case of bauxite used in the manufacture of cement, the lumps can be less than 10cmin size.

(b) Intermediate Industries involved in up gradation of mineral before end use:-There is no industry involved in up gradation of mineral bauxite before its end use. Onlymanual hands sorting of lateritic clay & laterite which are very low is Al2O3 is high in Fe2O3 &SiO2 is being done.(c) Detail requirement of other industries, captive consumption export:-Low grade bauxite is sold to other parties.(d) Physical & Chemical specification of buyers : -Physical & chemical specification of low grade bauxite used in cement manufacture is asunder:-Al2O3 : upto 30 %SiO2 :10 %( max)(f) Proposal for up gradation of ROM:-Except hand sorting (removal of lateritic clay & lateritic) no up gradation is required.

3.0 DESCRIPTION OF THE ENVIRONMENTAL

3.1 Preamble

Baseline environmental status in and around the mining lease area depicts theexisting environmental conditions of air, noise, water, soil, biological and socio-economic environment. The project as a center, a radial distance of 10 km isconsidered as study area for baseline data collection and environmental monitoring.The data was collected for various environmental attributes so as to compute theimpacts that are likely to arise due to proposed development activity by Grass RootsResearch & Creation India (P) Ltd. recognized by MoEF as per Environment(Protection) Act, 1986 & NABL through it Laboratory.

The main aim of the impact assessment study depends mainly on two factors. One isthe estimation of impact from proposed project on the environment and second oneis the assessment of the environmental condition. Both are key factors to arrive atthe post project scenario. The estimated impact due to the mine lease area can besuperimposed over the existing conditions to arrive at the post project scenario. Thescope of the baseline studies includes detailed characterization of followingenvironmental components:

Metrological conditions Ambient Air Quality Noise levels Water Quality (Surface + Ground water) Soil Quality Biological Environment

3.2 STUDY AREA

The project as a center, a radial distance of 10 km is considered as study area forbaseline data collection and environmental monitoring.

3.3 STUDY PERIOD

The baseline environment quality was carried out over a radial distance of 10 kmaround the mine during pre- monsoon season of 2015 covering the months of March2015 to May 2015.


III-3

3.4 METHODOLOGY / APPROACH

3.4.1 Methodology of EIA

Environmental Impact Assessment study has been conducted within an area of 10km radius around the ML area. The various steps involved in the study for thisproject are divided into three following phases.

• Identification of significant environmental parameters and assessing thebaseline status within the study area and assessment of pollutants envisageddue to proposed activities and the polluting activities in the study area onvarious environmental parameters.

• Perdition of impacts after superimposing the predicted pollution load over thebaseline condition.

• Prepare Environmental Management Plan for mitigation of impacts onenvironment arising out of the proposed activity.

3.4.2 Approach

Environmental monitoring in order to establish the baseline environmental status ofthe study area for Ambient air, Water, Soil, Land use, ecology, etc.

• Collection of site specific meteorological data at the mine site.• Carrying out a detailed biological study for the Core and Buffer Zone.• Literature review that includes identification of relevant data and articles

from various publications, various government agencies and other sourcesfor socio-economy, demography, meteorology, land use, ecology, etc.

• Identify various existing pollution loads due to mining and domesticactivities in the buffer zone.

• Evaluate the predicted impacts on the various environmental attributes inthe study area by using scientifically developed and widely acceptedEnvironmental Impact Assessment (EIA) Methodologies.

• Preparation an Environmental Management Plan (EMP) outlining themeasures for improving the environmental quality.

3.5. METEOROLOGICAL CONDITIONS

Meteorology is the key to understand the air quality. The essential relationshipbetween meteorology and atmospheric dispersion involves the wind in the broadestsense. Wind fluctuations over a very wide range of time, accomplish dispersion andstrongly influence other processes associated with them.

3.6.3: Baseline Scenario

a) Particulate Matter (PM10)

Particulate matter in general terms is the particulate matter in ambient air. Itincludes dust, smoke etc. In general some of the important sources of suspendedparticulate matter are mines. The following sources of suspended particulate matterin the study area are identified:

o Emission due to vehicular movemento Dust generation from ground or other mining operations

The minimum and maximum concentration of PM10 recorded within the study areawas 50.5 µg/m3 to 139.4 µg/m3 with the 98th percentile ranging between 63.3µg/m3 to 130.8 µg/m3.

The 24 hourly average values of PM10 were compared with the National Ambient AirQuality Standards (NAAQS) and found that some sampling stations recorded in thestudy area are above the applicable limits i.e., 100 µg/m3 for PM10.

b) Sulfur Dioxide (SO2)

Sulfur dioxide gas is an inorganic gaseous pollutant. Sulfur dioxide emissions areexpected to be emitted wherever combustion of any fuel containing sulfur takesplace. The sulfur in the fuel will combine with oxygen to form sulfur dioxide. Thefollowing sources of sulfur dioxide in the study area are identified:

Emissions from domestic/consumption of fuel (coal, diesel, etc) Emissions from DG sets used by mining activity and local residents

Sulfur dioxide in atmosphere can combine with water (moisture) in the air to formsulphuric acid aerosols that can corrode metal surfaces, fabrics and the leaves ofplants. Sulfur dioxide is an irritant to the eyes and respiratory system. Excessiveexposure to sulfur dioxide can cause bronchial asthma and other breathing relateddiseases as it affects the lungs.

The minimum and maximum concentration of SO2 recorded within the study areawas <5 to 6.8 µg/m3 with the 98th percentile ranging between 6.2 µg/m3 to 6.8µg/m3.


III-12

The 24 hourly average values of SO2 were compared with the National Ambient AirQuality Standards (NAAQS) and it was found that all sampling stations recordedvalues are below the applicable limits 80 µg/m3.

c) Oxides of Nitrogen (NO2)

The important sources of oxides of Nitrogen are from utilities and auto exhaust dueto vehicular movement in mine lease area. The following sources of oxides ofnitrogen in the study area are identified.

o Emissions from field burning of coal.o Emissions from vehicular movements in the study area.

Oxides of Nitrogen in the presence of sunlight will undergo reactions with a numberof organic compounds to produce all the effects associated with photochemicalsmog. NOX has inherent ability to produce deleterious effects by themselves liketoxicity. It causes asphyxiation when its concentration is great enough to reduce thenormal oxygen supply from the air.

The minimum and maximum concentration of NOx recorded within the study areawas 6.5 µg/m3 to 15.3 µg/m3 with the 98th percentile ranging between 12.7 µg/m3to 15.1 µg/m3.

The 24 hourly average values of NO2 were compared with the National Ambient AirQuality Standards (NAAQS) and it was found that all sampling stations recordedvalues are below the applicable limits 80 µg/m3.

3.7 NOISE LEVELS

Noise is one of the most undesirable and unwanted by-products of our modern lifestyle. It may not seem as insidious or harmful as air and water pollutants but itaffects human health and well-being and can contribute to deterioration of humanwell-being in general and can cause neurological disturbances and physiologicaldamage to the hearing mechanism in particular. It is therefore, necessary tomeasure both the quality as well as the quantity of noise in and around theproposed site.


III-13

3.7.1 Source of Noise

The main sources of noise in the study area are domestic activities, industrialactivities and vehicular traffic. The main occupation of the villagers in the study areais agriculture and business.

3.7.2 Noise Level in the Study Area

The baseline noise levels have been monitored at 7 locations within the study zone,using a sound level meter and noise level measurement locations were identified forassessment of existing noise level status, keeping in view the land use pattern,industrial area, Silence Zone, residential areas in villages etc., if available within 10km radius of the study area. The day levels have been monitored during 6.00 AM to10.00 PM and night noise levels, during 10.00 PM to 6.00 AM. The noise monitoringstations are shown in Figure 3.3 and represented in Table 3.6. The results arepresented in Table 3.8.

Note:1. Daytime is from 6.00am to 10.00 pm and Nighttime is from 10.00 pm to

6.00 am.2. Silence zone is defined as area up to 100 meters around premises of hospitals,

educational institutions and courts. Use of vehicle hours, loud speakers and burstingof crackers are banned in these zones

3.7.4 Baseline Scenario

The values of noise observed in some of the areas are primarily owing to vehiculartraffic and other anthropogenic activities. Assessment of night time Leq (Ln) variesfrom 38.1 to 54.6 dB (A) and the daytime Leq (Ld) varies from 46.3 to 68.4 dB (A)within the study area.

The status of noise quality within the 10 km zone of the study area is, therefore,within the MoEF standards.

3.8 WATER ENVIRONMENT


III-16

3.8.1 Water Quality

Sampling Frequency and Sampling Techniques

Parameters for analysis of water quality were selected based on the utility of the particularsource of water as per MoEF guidance. Hence quality of ground water was compared withIS: 10500: 1991 (Reaffirmed 1993 With Amendment NO -3 JULY 2010) for drinking purposes.Surface water quality was monitored for parameters as per Methods of Monitoring &Analysis published by CPCB and it was rated according to the CPCB Water Quality Criteriaagainst A, B, C, D & E class of water. Water samples were collected as Grab water samplefrom sampling location in a 5 liter plastic jerrycan and 250 ml sterilized clean glass/petbottle for complete physico-chemical and bacteriological tests respectively. The sampleswere analyzed as per standard procedure / method given in IS: 3025 (Revised Part) andstandard method for examination of water and wastewater Ed.21st, published jointly APHA,AWWA and WPCF.The surface water quality is compared with CPCB water quality criteria mentioned in Table3.16 below:

As per the standard practice, one sample from each station was taken each month inthe study period. Sampling was done by standard sampling technique as per theStandard Methods. Necessary precautions were taken for preservation of samples.

3.8.2 Result & Conclusion:

The pH limit fixed for drinking water samples as per IS-10500 Standards is 6.5to 8.5 beyond this range the water will affect the mucus membrane and orwater supply system. During the study period, the pH was varying for groundwaters from 7.62 to 8.21 & pH was varying for surface waters from 7.7 to8.16. The pH values for all the samples collected in the study area duringstudy period were found to be within the limits.

The desirable limit for total dissolved solids as per IS-10500 Standards is 500mg/l where as the permissible limits in absence of alternate source is2000mg/l, beyond this palatability decreases and may cause gastro intestinalirritation. In ground water samples collected from the study area, the totaldissolved solids are varying from 1668 mg/l to 4249 mg/l the TDS of thesamples above the permissible limit of 2000 mg/l.

The desirable limit for chlorides is 250 as per IS-10500 Standards where aspermissible limit of the same is 1000 mg/l beyond this limit taste, corrosionand palatability are affected. The chloride level, in ground water samples 550mg/l to 1539 mg/l. & for surface water it is 42 mg/l to 18060 mg/l thechloride samples are within the above limits.

The desirable limit as per IS-10500 Standards for hardness is 300 mg/l whereas the permissible limit for the same is 600 mg/l beyond this limitencrustation in water supply structure and adverse effects on domestic usewill be observed. In the ground water samples collected from the study area,the hardness is varying from 410 mg/l to 1388 mg/l.

Fluoride is the other important parameter, which has the desirable limit of1mg/l and permissible limit of 1.5 mg/l. however the optimum content offluoride in the drinking water is 0.6 to 1.5 mg/l. if the fluoride content is less


III-36

than 0.6 mg/l it causes dental carries, above 1.5 mg/l causes flurosis. In theground water samples of study area the fluoride value were in the range of0.7 mg/l to above limit in surface water it varies from 0.6 mg/l to 1.3.

Overall all the samples collected from the study area were found to be forconsumption, Most of ground water samples limits. Most of the heavy metals in allsamples are below detectable limits.

3.9 Soil Characteristics

The composite soil samples were collected from site and the study area and wereanalyzed for characterization. The locations of the monitoring sites are depicted inFigure 3.5 and given in Table 3.17 Showing Soil Sample Collection Points markedwithin the Study Area.

3.9.1 Methodology

The soil samples were collected in the month of April - 2015. Soil samples werecollected from 7 locations, at each of these locations, the sub-locations wereidentified randomly from where soil was collected from 30 cm below the surface.The final samples represent homogenously mixed soil from these sub-locations foreach location. The samples were filled in polythene bags, labeled in the field withnumber and site name and sent to laboratory for analysis. The test results are givenin Table-3.18.

3.9.2 Results of Analysis of the Soil

Physical characteristics of soil were characterized through specific parameters vizbulk density, porosity, water holding capacity, pH, electrical conductivity andtexture. Soil pH plays an important role in the availability of nutrients. Soilmicrobial activity as well as solubility of metal ions is also dependent on pH. In thestudy area, variations in the pH of the soil were found to be Neutral (7.46 to 7.86).Electrical conductivity (EC) is a measure of the soluble salts and ionic activity inthe soil. In the collected soil samples the conductivity ranged from 241-432µmhos/cm.

The soils with low bulk density have favorable physical condition where as thosewith high bulk density exhibit poor physical conditions for agriculture crops.

3.10 Land Use/Land Cover Mapping

To assess the land use pattern surrounding the 10 km radius of the site, a detailedstudy was carried out. The land use pattern study reveals that the 10 km environs ispredominantly settlement area in the East while the entire West is occupied bysome Agriculture and Reserved or protected forest land.

3.12 BIOLOGICAL ENVIRONMENT

3.12.1 Introduction

Biodiversity reflects the potential of a regional ecosystem. Biota of a particular area is

considered as indicators of the environment as they quickly respond not only to one

environmental factor but also an interactive group of factors. These communities influence

and react sensitively to changes in the balance of environmental stresses.

Biological diversity comprises the variability of genus, species and ecosystems and is very

crucial for maintaining the basic processes on which the life depends. On the basis of

biological physiology biodiversity broadly can be divided into two category i.e. the floral

diversity and faunal diversity. Conservation of the biodiversity is essential for the

sustainable development as it not only provides the food, fodder and medicine, but also

contributes to improvement of essential environmental attributes like air, water, soil, etc.

Before starting any Environmental Impact Assessment study, it is necessary to identify the

baseline of relevant environmental parameters which are likely to be affected as a result of

the operation of the proposed project. A similar approach has been adopted for conducting

the study on Biological Environment for this Project. Both terrestrial and aquatic ecosystems

have been studied to understand the biological environment nearby the project site.

The study was conducted in the project area to assess all possible consequences on the

biological environment. Flora and fauna surveys and data collection conducted for assessing

the biological diversity and its status over a period of time that forms an integral part of

Impact Assessment Techniques. The present study is highlighting the various issues

pertaining to floristic diversity and the faunal wealth in the core area i.e. Virpur (Gunawali)

Bauxite Mine, District Devbhoomi Dwarka (Gujarat) and buffer zone i.e. area within 10 km

radius.

3.12.2 Description of Study

Virpur (Gunawali) Bauxite Mine is situated near the Virpur village which is spread over an

area of 55.2520 ha and located in the Devbhoomi Dwarka district of Gujarat near the

Kalyanpur tehsil.

Devbhoomi Dwarka District is located in the North West of Gujarat. It is bounded partly by

Gulf and partly by the desert of Kutch in the North, Porbandar district in the South, Jamnagar

district in the East and Arabian Sea in the West. The District has a geographical area of

40, 51 sq. km. Devbhoomi Dwarka district is situated under the Seismic Zone-IV as per IS-

1893 (part-1)-2002. The district has a hot semi-arid tropical climate. The district has

maximum agricultural land out of its total geographical area. The district is not enriched

with forest. The forest of Devbhoomi Dwarka district comprises of tropical deciduous

vegetation due to high temperature and humidity.

Present mining lease area (Gunawali) is located on the barren land in the Devbhoomi

Dwarka district near the Sea shore. There is no any agriculture land nearby the mining lease

area. Some agriculture land is present away from the mining lease area. The main crop of

the buffer area is Cotton (Gossypium herbaceum)followed by Castor (Ricinus communis), Ground

nut (Arachis hypogaea), Bajra (Pennisetum typhoides), Jowar (Sorghum bicolor), Jeera/Jeeru

(Cumium cyminum), Wheat (Triticum aestivum), Tuver (Cajanus cajan), Mug (Magna radiate),

Mango (Mangifera indica) and Chikko (Manikara zapota).

As an Eco-Sensitive zone, Marine National Parks and Sanctuary, Jamnagar is situated at the

distance of 1 km away in north-West direction (Fig. 1).

3.12.4 Agricultural landThe economy of Gujarat is predominantly agricultural and rural in nature, with wide

fluctuations in the growth rate due to uncertainties in agricultural production.

Agriculture in Devbhoomi Dwarka district is primarily rain-fed. The irrigation from the

mining pit is observed in many localities. It is observed that these mining pits are acting as

an option for rainwater harvesting in this water scarcity region.


III-59

Maximum area of buffer zone (within 10 km radius of the site) is covered with agricultural land.

The crops grown in Devbhoomi Dwarka district as well as buffer zone of Gunawali Mine

(Virpur) were Cotton (Gossypium herbaceum), and Castor (Ricinus communis) and during monsoon

period, Ground nut (Arachis hypogaea), Bajra (Pennisetum typhoides), and Jowar (Sorghum bicolor)

among major crops. While, minor crops practiced in this region during monsoon are Jeera/Jeeru

(Cuminum cyminum) and Ground nut (Arachls hypogaea). Minor crops practiced in this region during

winter are Wheat (Triticum aestivum) and Til (Sesamum indicum). Some others crop such as Tuver

(Cajanus cajan) and Mug (Magna radiate),Mango (Mangifera indica) and Chikko (Manilkara zapota)

plantation were also observed in the few villages in the buffer area. In Devbhoomi Dwarka

district has 62% land as cultivable land of its total Geographical area.

3.12.3.1 Fishery

In Gujarat, village ponds are very good resource to undertake effective fish culture which

can generate employment at village level. For the financial and administrative support of

fisherman, Gujarat Fisheries Central Co-operative Association Limited (GFCCA) has been

established which is an apex cooperative body of the fishermen cooperatives in the State of

Gujarat. The Devbhoomi Dwarka district is endowed with some dams, ponds and canal

which support fisheries activities. Besides, this a large number of private pond aquaculture

practice are continued by local fisherman communities.

Some common fish species present in all the water bodies of Gujarat are as Catla catla,

Cirrhinus cirrhinus, Labeo rohita, Mystus Cavasius, Glossogobius giuris, Mastacembelus

armatus and Puntius sp.

The opencast mining operations in general cause environmental degradation and ifadequate control measures are not taken to prevent/mitigate the adverseenvironmental impacts, these operations may cause irreversible damage to the eco-system. The environmental parameters most commonly affected by mining activitiesare:

Topography and drainage Air quality Noise levels and ground vibrations Water resources and quality Landuse Pattern Soil quality Flora and Fauna Socio-Economic conditions; and Occupational Health

Various environmental impacts, which have been identified due to the miningactivities, are discussed in the following sections and mitigation measures aresuggested.

4.1.1 Impact on Topography and Drainage

(a) Topography: - The Topography of the terrain around Virpur (Gunawali), Mewasa,Mota Astota and other village is marked low lying narrow winding latertte ridgeswith intervening broad flat and undulating valley gradually sloping towards the coastin the west to south westerly direction. Being a drought prone area, the rain fall isscanty and hence there are no perennial rivers. The nallas and rivers which remainsmostly dry during major part of the year show a dendritic drainage pattern. Thenarrow winding ridges normally show a low dip slope towards east – north – eastand relatively escarpment slope towards west- south – west.


IV-3

The general topography of the lease area is relatively a flat terrain having very lowSlop. The highest RL is 26 m RL in south part of the lease area and lowest RL is 10.53m RL in north part of the lease area. Drainage of the lease area is towards north intonatural drainage course.

(b) Drainage Pattern: - There is no river or nalla or well exist in the lease in the leasearea. There is no fix drainage pattern Rain fall in the area is Scanty. During rains,water flows higher elevation to lower elevation in all direction. Part of rain water isalso collected in working pits, which are soon dried up as rains are not regular. Thereis a natural drainage system within the lease area. The drainage system in the arearemains from south to north direction.

4.2 AIR ENVIRONMENT

4.2.1 Anticipated Impacts

The mining will be carried out by opencast other than fully mechanized method. The air

borne particulate matter generated by ore and handling operations and transportation of ore is

the main source of air pollutant. The dumpers and HEMM will emit smoke and noxious gases

and un-burnt hydrocarbons.

The emissions of Sulphur dioxide (SO2), Oxides of Nitrogen (NO

2) contributed by diesel

operated excavation/loading equipment and vehicles plying on haul roads are marginal.

Prediction of impacts on air environment has been carried out taking into consideration

proposed production and net increase in emissions.

Air pollution sources in the operating mine have been classified into three categories:

i. Drilling and Blasting operations

ii. Excavation and Loading of ore

iii. Transportation of ore on the haul road

Water tankers with spraying arrangement will be used for regular water sprinkling on the haul

roads to ensure effective dust suppression. The dumpers are well maintained so that exhaust

smoke does not contribute abnormal values of noxious gases and un-burnt hydrocarbons.

In order to assess the impact due to Bauxite production of 500 TPD on air environment,

prediction has been carried out.

4.2.4 Air Pollution Impact Prediction through Dispersion Modeling

Prediction of impacts on air environment has been carried out by employing Industrial

Source Complex Short Term (ISCST3) dispersion model.

The ISC area source model is used to simulate the effects of fugitive emissions from sources

such as topsoil, OB and ore loading and unloading and blasting, and transportation. The ISC

models use a numerical integration approach for modeling impacts from area sources. The


IV-5

ISC models accept rectangular areas that may also have a rotation angle specified relative to a

north-south orientation.

The dust dispersion modeling requires the following data: Micro – meteorological data Mining data Dust concentration data

The impact has been predicted over a 10 km radius area with mining area as the centre. To

obtain greater resolution, the receptors are defined with respect to 500 x 500 m grid point to

have better results. GLC have been calculated at every 500 m grid point to have better results.

4.2.2 Emissions Details

Blasting, loading - unloading and transportation of ores and overburden will be the main

polluting source in the proposed mining activities releasing Particulate Matter (PM10)

affecting Ambient Air of the area. Emission during Blasting, Loading and unloading was

calculated by the area sources. Transportation of the ore by tucks on the haul road was

calculated by the area source which was combination of line sources with each truck loaded

with ore transported over the haul road of the mining area.

The open pit mining involves the following general processes:

• Removal of the vegetable layer (top soil)

• Removal of overburden

• Removal of the useful geological material

• Hauling of the useful geological material

Each one of these mining operations is, in turn, divided into various different activities, that

depend on the technologies used. Each activity is an emission source. The Table - 4.1 shows

the emission factors considered for modeling exercise.


IV-6

Table-4.1 Emission Factors

Activity type Emission

Soil Loading & Unloading 7.85 x 10-6 kg PM10/t

Soil Transportation 1.47 kg PM10/VKT

OB Loading & Unloading 7.85 x 10-6 kg PM10/t

OB Transportation 19.87 kg PM10/VKT

Blasting 2.57 x 10-2 kg PM10/blast

Mineral loading 2.56 x 10-3 kg PM10/t

Mineral unloading 7.85 x 10-6 kg PM10/t

Mineral Transportation 2.88 x 10-1 kg PM10 VKT

Emission was calculated with the help of emission factor calculated by formula given below

E=TP X EF

Where E= Emissions (tonnes/year)

TP= Annual Throughput

EF= Emission Factor

4.2.5 Meteorological parameters

The meteorological data file for the Short Term model normally consists of meteorological

data, beginning with hour 0.1:00 of March 1, 2015 and ending with hours 24:00 of May 31,

2015. The hourly meteorological data recorded continuously at site for the same period. The

mean meteorological data recorded at the site has been used for the modelling. In absence of

site specific mixing heights, mixing heights published in IMD Publication “Atlas of Hourly

Mixing Height and Assimilative Capacity of Atmosphere in India” by S.D. Attri, Siddhartha

Singh, B. Mukhopadhyay, and A.K. Bhatnagar (2008) has been used.

After processing of area source data in ISCST3, isopleths for fugitive dusts (Line Source +

Area Source) is generated, this is presented in figure 4.2. The software selects the

meteorological data of the worst day which is different from the seasonal wind rose.

A summary of the PM10 concentrations predicted for the proposed mine are presented in

The excess of the 24-hour PM10 standards is observed. The 24-h maximum incremental GLC

of PM10 9.48 µg/m3 occurred at the center of the mine site. The value of PM10 at the project

site was 140.2 µg/m3observed after superposition of base-line value of 130.7 µg/m3 on the

incremental GLC of 9.48 µg/m3 under combined impact of loading, unloading, transportation

of ore by trucks over haul road and blasting at the mining area.

Contours of the maximum predicted 24-hour average PM10 concentrations (Figure 4.2)

indicate that 9.48 µg/m3 are predicted to occur within mine site from the mining operations.

However, at the receptors of 500m downwind from project site the contour of 1.5 µg/m3 has

occurred and at the rest of the receptors in 10 km radius there is no effect of mining and the

PM10 concentrations well within the PM10 standards. Hence peak concentrations are

localised to operations.

4.3 Water Environment

4.3.1 Impact on Water Resources

The mining activities will not produce any kind of pollutants. So, there is no any bad impactwill be introduces on local surface water. On the other hand, ground water will also be safeand not disturbed as ground water table in this area. There is no river or nala crossing in the


IV-10

lease area. The rain water follows through the natural slope in eastern direction of the area.Rain water of the region ultimately goes into the Arabian Sea.

4.3.2 Impact on Water Quality

Water is required for mining operations mainly for sprinkling on haulage roads and at openfaces during mining for suppression of dust. Around 8.0 kld of water is required for miningactivities. Arabian Sea is near from the lease area. There will be insignificant impact on thesurface water resources due to withdrawal of water required for mining operations.

Impact on Surface Water Quality and Sediment Load

Mining activity increases sediment load and total dissolved solids in streams due toerosional activity of overburden dump and loosened soil by blasting activity. Thefollowing measures will be taken up by project authorities to reduce this load.

1. Dense plantation.2. Construction of siltation ponds/tanks.3. Construction of Garland drains.

Physico-chemical characteristics of surface water samples collected from rivers andnalas in the buffer zone are under the desirable limits. Except, water of Pindara Bayrecorded higher values for Conductivity, Chloride, Sulphate, Sodium and Potassiumas compared to Ran River and Ni-Pal Pond. The higher values documented onaccount of higher salinity and hardness.

No wastewater generation is envisaged due to the mining operations. The sanitarywastewater will be sent to septic tanks. No impact of wastewater generation on thesurface water is envisaged, as there is no discharge into surface water resources.

Impact on Ground Water Quality

Ground water pollution can take place only if the mining rejects contain chemicalsubstances. However, the deposit does not contain any harmful ingredients. Hence,no impact on groundwater quality is envisaged.

4.3.3 Wastewater Generation, Treatment & Disposal

The wastewater generation in the mining process is not envisaged. The sanitarywaste will be routed to septic tanks followed by soak pits. The sump also behaves asprimary settling tanks for the mine water. Thereby, the suspended solids, the major


IV-11

contaminant added to the mine water inflow, would settle down and clean tappedwater will be discharged on to the surface.

4.3.3.1 Measures for Minimizing Adverse Impacts

Mine Drainage

The following facilities will be provided for proper mine drainage:

The garland drains will be developed in advance for each mine stage so thatwater is collected in these garland drains and discharged properly outside the pit.

Working faces will be laid such that the water from the working areas will flowinto the sump by gravity from where it will be pumped out.

Face pumps of adequate capacity will be provided at working faces to keep thesedry.

Slurry pumps will be provided to deal with slurry formed during rainy season. Surface Water Pollution Control Measures

Retaining walls of adequate dimensions will be provided at the toe of dumps andthe unstable OB benches within the mine to prevent wash off from dumps andsliding of material from benches. This will help in preventing silting of waterdrains/channels;

The water channels/drains carrying the rain water from the mine will be providedwith baffles and settling pits to arrest the suspended solids, if any, present in thiswater;

The worked out slopes will be stabilized by planting appropriate shrub/grassspecies on the slopes. This will help in preventing wash-off of ore from theseslopes;

The mine water will be regularly tested for presence of any undesirable elementsand appropriate measures will be taken in case any element is found exceedingthe limits prescribed by CPCB.

Ground Water Pollution Control Measures

The domestic sewage from the canteen and toilets will be routed to septic tanks.


IV-12

Regular monitoring of water levels and quality in the existing open wells andbore wells in the vicinity will be carried out. If found necessary, additionalobservation wells will be sunk for monitoring the water levels and quality aroundthe mine representing both upstream and downstream conditions.

Artificial Recharge and Rain Water Harvesting

For reducing the impact of lowering of water level and pollution level in thesurroundings of the proposed opencast workings, the following methods of artificialrecharge and rain water harvesting methods will be adopted.

1. There is no major roof top area is present in lease area. Only small office ispresent at mine lease. Rain water will be collected and recharge in mined out pitsthrough garland.

2. Rain water which flows away from the area as runoff will be accumulated inmined out pit through garland drain. Water stored in mined out pits inducesgroundwater recharge.

3. Rain water and sump water.4. No STP plant is require at mining lease because very small quantity waste water

will be generated from domestic uses water. Waste water will be collected insoak pit and utilize for dust suppression and green belt development.

The project will through these actions enhance the water levels in the area.

4.4 Impact on Land Use

The proposed opencast mine will result slight change and disturbance of the land usepattern of the Mine Lease area. The land degradation is expected during miningactivities like excavation, overburden dumping, soil extraction etc. Land requirementfor the project has been assessed considering functional needs. The lease area is of55.2520 ha (Mine working area 37.167 ha) Fertility of land is very poor. Within theproposed area the pre-mining break up of land is as follows:

Existing Land Use:

Agriculture land and govt. wastelands cover the terrain surrounding ML area. Apartfrom this, quite a number of mining leases area also found all around the ML.

At the conceptual stage, about 23.3954 ha area will be disturbed on account ofmining activities. A part of excavated area will be converted into water reservoir. Inaddition to this, about 19.5512 ha of undisturbed area will also be covered underafforestation and 0.0100 ha area will be utilized for Roads.

In mining operation, neither toxic effluent nor toxic solid waste will be generated.Hence, the soil quality in the vicinity is not expected to be adversely affected due tomining operation.

Hazard and Risk Assessment of OB Dumps

Hazard of OB dump failure is mainly governed by following factors:

1. Height of benches


IV-15

2. Slope of benches3. Nature of material4. Slope of foundation rock5. Nature of foundation rock6. Drainage of foundation7. Depth of ground water table

The following precautions will be taken to reduce the risk of dump failure:

1. OB benches will be of <30m height in each tier.2. The angle of repose of3. OB benches will be around 37o.4. The soil from the foundation ground will be scrapped before starting OB

dumping.5. Drainage control structure like garland drain will be made around OB dump area

to avoid water flow during monsoon below the OB dump.6. Levelling, grading and drainage arrangement for top of OB dumps.7. Technical & Biological reclamation.No adverse impact is anticipated on land use of buffer zone associated due to theproposed mining operations, as all the activities will be confined within the projectsite only.

Rehabilitation and reclamation is an integral part of the environmental managementplan, Figure-4.4 reflects this aspect.

FIGURE- 4.4Environmental Management Plan

4.5 Impacts due to disposal of Overburden


IV-17

In the proposed mining plan topsoil will be generated but no OB will be generatedthe 5% ROM will be generated as mineral waste.The waste that is likely to be generated will be in the form of associated clay with thebauxite horizon as mineral reject, which is below the threshold grade, and has nosale value & of no use. Hence considered as a waste.The yearly rate of generation of the waste has been described in detail in the miningchapter and the date given there is presented in a tabular from below. For the soiland waste the expansion factor considered is 1.3.Top soil will be generated during modified mining plan period.A tabular statement showing volume of soil, OB mineralized waste:-

Waste generated during production of mineral bauxite will be stacked in pit floorafter excavation of bauxite upto full thickness. Top soil will be spread over statuarybarrier for plantation.(b) Proposed dumping area: -In the proposed modified mining plan. It is proposed that waste generated duringmining plan period will be stacked at pit floor after excavation of bauxite. Soil will bespread over statuary area for plantation. Part of mined out land will be used as waterreservoir.(c) Disposal of waste:-No Backfilling will be done in the area after complete extraction of full thickness ofbauxite. The waste generated during modified mining plan period will be stacked inthe pit floor. As volume of voids (area to be worked) is much more than materialavailable for backfilling, entire mined out area up to original ground level will notpossible. Therefore mined out lease area will be used as water reservoir. Fencing willbe carried out around the water reservoir.

4.6 Impact on Air Quality


IV-18

Air pollution sources at the mining area can be classified into three categories, viz.,area sources, line sources and instantaneous point sources. Extraction of Bauxite byvarious activities in mining area is considered as an area source. Blasting is the mainsource of instantaneous point sources. Majority of the heavy machinery is operatedon diesel. The mining activity is likely to contribute Suspended Particulate Matter(SPM), Dust from area sources and Oxides of Nitrogen (NOx) and hydrocarbons fromautomobile exhaust. The existing baseline concentrations of pollutants are withinthe limits prescribed by CPCB. The sources of pollutants from mining activities aregiven in Table-4.4.

TABLE-4.4SOURCES OF POLLUTANTS

Sr. No. Source Type of Pollutant1 Mining activity (drilling, blasting, loading) SPM, NOx2 Transport of Overburden or soil for dumping/

backfill and bauxite to sorting/sizingSPM

3 Dumping of waste SPM4 Sorting of bauxite and loading SPM5 Transportation of sorted bauxite SPM, NOx

Impacts from Area Sources

The area sources include mine pit and its activities covering drilling, blasting, hauling,loading/unloading and stockpiles.

The dust emissions from the above areas will be fugitive in nature and maximumduring summer season (when the wind velocities are likely to be high) and almost nilduring the monsoon season. The dust emissions are likely to be confined to the minepremises only.

Impacts from Line Sources

The proposed plant activities will involve transport of ore from the site. The totalproposed traffic details due to the project are given in Table-4.5. The trucks will beadequately covered/ bagged; hence the fugitive emissions will be avoided.

The transportation of raw materials will involve generation of additional traffic ofabout 25 trucks per hour. Compared to the existing traffic on highway, theincremental traffic density due to the proposed plant (25 trucks per hour) will benegligible.

The annual and 24-Hr average concentrations of PM10 are lower than the NAAQS atmining and residential places. In order to reduce the effect of PM10 a few additionalmeasures may be implemented.

Restriction of trucks/dumpers speed and overhauling, and regular road cleaning areessential in order to control dust pollution from transportation, together with waterspraying on roads. Washing of dumpers/ trucks’ wheels/body at an appropriatedistance from site entrance, loading and unloading in area protected from wind,minimization of drop heights, use of sheet or cover on loaded vehicles andapplication of water sprays to moisten transported material is also essential.Installation of sprinkling system along with application of binding agents, chemicalson unpaved roads are required. In addition, unpaved roads should be converted toblack topped roads, with regular maintenance/ repair of roads to maintaincompactness, gradient and drainage, sweeping of unpaved roads and the impositionof speed limits on trucks and other vehicles. A Green belt should be developedhaving plants with thick foliage, which will effectively attenuate the dustconcentration.

4.7 Proposed Mitigation Measures for Dust Suppression

Bauxite is a hydrated oxide of aluminum. It is a mixture of two or more hydroxidescorresponding to Gibbsite (Al2O3.3H2O) and Boehmite (Al2O3.H2O). The moisturecontent in Bauxite is around 3% to 7%. Therefore emissions due to mineral handling


IV-20

during mining operation are not much and restricted to the lease area only. Airpollution is caused mainly due to dust generation added with gaseous emission fromtransportation activities along with mining operation like drilling, dozing, blasting,loading, haulage etc. Proper mitigation measures will be practiced during miningactivities to control air pollution load below the prescribed limits.

In the proposed project, drilling will be done with latest drill machines with vacuumsuction for dust extraction thus the likelihood of dust emission from drilling activities isnegligible. The burden and spacing for the hole will be 2m and 3m for effective depthof 6.00m. The power factor per Kg. will be 8.00 MT. About 50% of ROM bauxiteneeds blasting therefore about 110Kg. explosive will be required per day. 14 or 15holes will be required daily.

Blasting is the main source of instantaneous point sources. Blasting is usually carriedout by deep holes. SPM and NOx emissions are envisaged during the blasting andtransportation operations. The large quantity of dust will be wind borne due toblasting but due to the proposed greenbelt around the mine, the spread of dust willbe arrested. But these are kept under control by monitoring regularly the emissionsfrom exhaust and using appropriate control measures by sprinkling of water on haulroads etc. The gaseous emissions like Oxides of Nitrogen from the blasting activity willbe instantaneous and will prevail for shorter duration. The blasting will be carried outonly between 2 pm to 3 pm during noon when normally low wind conditions prevailand temperature inversions are not likely to occur.

In addition to the above the production of blast fumes containing noxious gases willbe reduced by the following methods:

Blasting will be carried out only during the daytime Controlled blasting will be practiced Mitigative measures for control of ground vibrations and to arrest fly rocks and

boulders will be implemented Proper and proportionate mixing of fuel oil with ammonium nitrate to ensure

complete detonation Use of adequate booster/primer: and Proper stemming of the blast hole.

Fugitive Emissions

Fugitive dust emissions from the proposed project would be significant as there willbe air pollution due to activities like transport of bauxite and overburden and


IV-21

generally due to the movement of vehicles on the roads. The proposed greenbeltand regular water sprinkling will help reduction in fugitive emissions.

Automatic water sprinklers will be installed in the mine. Pressurized water will besprinkled. Dust generation is reduced by using sharp teeth for shovels.

With the proposed control measures, the fugitive emissions will be insignificant interms of their impact on environment.

The proposed air pollution mitigation measures are as follows:

• Regular water sprinkling on haul roads, loading and unloading points and transferpoints will be carried out.

Wet drilling of mine to reduce the dust generation from the drilling operations; Water spraying on mine faces to control dust emanated from loading and

handling operations; Water spraying over the muck pile to be loaded in order to reduce dust

generation during loading operations; Bauxite will be transported by tarpaulin covered vehicles and not overloaded to

avoid dust emission; Vehicular emissions will be kept under control and regularly monitored. Measures will be taken for maintenance of vehicles used in mining

transportation of mineral Extensive Plantation of trees of different variety in Bauxite storage yard; Dust masks to all workers working in dusty atmosphere; A good housekeeping and proper maintenance which will help in controlling

pollution; and• Periodical monitoring of air samples at various locations, and it will be ensure

that the ambient air quality parameters conform to the norms prescribed by theCPCB/SPCB in this regard.

4.8 Noise Environment

4.8.1 Noise Impact on Working Environment

Mining operations will be the main sources of noise pollution. Noise due to vehicularmovement will be intermittent, but will also add to the background noise level.

Once the mine becomes operational, there will be the following sources of noise inthe area:


IV-22

Drilling; Blasting; Operation of HEMM; and Vehicular Movement.

It has been observed that mechanization of mine generally leads to higher noiselevels if not properly controlled. Operation of drills, shovels, dumpers, pay loadersand dozers involve noise generation above 90 dB (A), which is the prescribedThreshold Limit Value. However, the expected noise levels are not likely to have anyeffect from the occupational health point of view.With the mining operations, due to the deployment of machinery, drilling andblasting for mine development, excavation, and transportation of bauxite and men,it is imperative that noise levels would increase. However, as the mine leaseboundary is located 1.0-km away from the nearest settlement, the expected noiselevels will not have significant effect on the community.

Noise Generated due to Drilling

The drilling operations in mine will be carried out by using 6” dia rotary percussivedrills. The typical Noise levels due to drilling at1-m distance will be about 85 – 90 dB (A). However, it is proposed to provide inbuiltcabin for drill operators with ear muffs/ear plugs.

The mine site where heavy earth moving machinery will operate, noise level will bemore than the stipulated 90 dB (A) norm of DGMS. The noise level will be within thetolerance limit at a distance of 15 to 20 m. The protection measures for theoperators of the equipment will reduce the impact.

The noise produced by blasting will be for extremely short duration of around 0.5seconds, though with a high intensity. The impacts over the surrounding habitat canbe minimized by adopting adequate precautions during blasting and also by properlyscheduling it as indicated in the management plan. Development of greenbelt alongthe periphery of the mine site is expected to act as an effective barrier against itspropagation of sound waves towards the nearby human settlements.

4.8.2 Noise Generated Due to Blasting

Noise generated from blasting is always instantaneous. It takes less than 5 secondsto occur. Noise of blast is site specific and depends on type, quantity of explosives,dimensions of drill holes, degree of compaction of explosive in the hole and rock.


IV-23

The noise levels during blasting operations are likely to be in the range of 120-140 dB(A) at 50-200 m distance from the blast site. The noise levels tend to decrease withdistance. Blasting will be carried out maximum two times per week between 12.00Noon to 2.00 PM. As the blasting is likely to last for very short duration depending onthe charge, the noise levels over this time will be instantaneous and short induration.

The noise levels in many situations will be above Threshold Limit Value. Exposure tonoise levels, above Threshold Limit Value may have detrimental effect on theworkers' health. Mine workers working for more than 4 to 4.5 hours per shift will begreatly affected, unless suitable mitigatory measures are taken. The adverse effectsof high noise levels on exposed workers may result in:

Annoyance; Fatigue; Temporary shift of threshold limit of hearing; Permanent loss of hearing; and Hypertension and high blood cholesterol, etc.

Noise pollution poses a major health risk to the mine workers. When noise in theform of waves impinges the eardrum, it begins to vibrate, stimulating other delicatetissues and organs in the ear. If the magnitude of noise exceeds the tolerance limits,it is manifested in the form of discomfort leading to annoyance and in extreme casesto loss of hearing. Detrimental effects of noise pollution are not only related tosound pressure level and frequency, but also on the total duration of exposure andthe age of the person.

Frequency levels and associated mental and physical response of humans are givenin Table-4.6.

It is a well accepted fact that noise pollution causes fatigue to operating personnel.Provision will be made to keep down the noise level to the extent it is feasible.

4.8.3 Noise Generated due to Excavation and Transportation

Typical noise levels generated during excavation, loading and transportationactivities of the mining activities are presented in Table-4.7.

EQUIPMENT

Sr. No. Name of the Equipment Nos. Noise at Source dB(A)1 Near Tipper (at full race) 2 75 - 902 Excavators 4 75–90

The total noise from all of the above equipments occurs only when all theequipments operate together and simultaneously, which is a remote possibility.

It is proposed to provide air conditioned cabins in Excavators and Tippers to reducenoise impact to the operators.

Noise Dispersion from the Mine

The noise generation from the mine will be from various sources, which will beoriginating from various locations within the Mines. For the purpose of noisedispersion, it is assumed that all the noise generating sources from the mine as onesource. The dispersion of this noise is computed by using the model.

4.8.4 Mitigation Measures


IV-25

The noise level control measures at various stages of the mining will be as givenbelow:

Use of Hydraulic drills with in-built cabin; Proper maintenance and lubrication of all moving parts of machines; Non-moving parts of machine will be properly fastened; Blasting will be well designed and arranged in such a way that only one or two

holes are blasted at a time with the use of short delay detonators in combinationwith sequential blasting machine;

No trunk line of detonating fuse will be used on surface (Even if detonating fuseis used as trunk line with cord relays, then it is covered with clay properly);

Primary blasts will be designed such that boulder generation will be minimum; Secondary blasting will be avoided; Explosives will be blasted into confined stage or optimum stemming column will

be maintained for holes during charging of hole; Blasting will be done only during afternoon hours when temperature inversions

are not likely to be there and air density is less; Blast of optimum size will be taken to keep noise level of blasting within 130

dB(A); No blasting will be done when the sky is cloudy because cloud cover can cause

reflection of pressure wave block to the ground at some distance from blast; Non-electric down-the-hole detonators will be used thus reducing noise level

during blasting operation

4.8.5 Occupational Exposure Mitigation Measures

Cabins will be provided for hydraulic drill machines; Earmuffs / ear plugs will be provided to personnel to abate noise; Silencers are provided to modulate the noise generated by machines; and Reducing the exposure time of workers to the higher noise levels.

4.9 Impact due to Ground Vibrations

Ground vibration, fly rock, air blast, noise, dust and fumes are the deleterious effectsof blasting on environment. The explosive energy sets up a seismic wave in theground, which can cause significant damage to structures and disturbance to humanoccupants. It causes major damages to the pit configuration too.


IV-26

When an explosive charge is fired inside the blast hole, it is instantly converted intohot gases, which exert intense pressure on the blast hole walls. High intensity shockwaves propagate radially in all directions and cause the rock particles to oscillate.This oscillation is felt as ground vibration. The proposed mining operations usingdeep hole drilling and blasting using delay detonators are bound to produce groundvibrations.

Blasting, in addition to easing the hard strata, generates ground vibrations andinstantaneous noise. Ground vibration from mine blasting is expressed by amplitude,frequency and duration of blast. The variables, which influence ground vibrations arecontrollable and non-controllable. The non-controllable variables include generalsurface terrain, type and depth of overburden and wind. Similarly, the controllablevariables include type of explosives, charge per delay, delay interval, direction ofblast progression, burden, spacing and specific charge and coupling ratio.

The oscillation of rock particles is called Particle Velocity and its maximum value iscalled Peak Particle Velocity (PPV), which is measured in millimeter per second. Thestandards for safe limit of PPV are established by Director General of Mines Safetyfor safe level criteria through Circular No. 7 dated 29/8/1997. The safe level criteriaPPV as mentioned in Circular No. 7 of DGMS is presented in Table-4.8.

IV-27

As the distance increases, the PPV value is likely to reduce. The ground vibrationsgenerated by blasting during the mining operations will be well within the standardsprescribed by DGMS by controlled blasting. Ground vibrations are not likely to affectthe structures in the vicinity of mine lease area.By adopting controlled blasting, the problems will be greatly minimized at mines. Theimpacts are also minimized by choosing proper detonating system, optimizing totalcharge and charge/delay. Noiseless trunk delays to minimize the noise due to airblast, non-electric (NONEL) system of blasting for true bottom whole initiation,muffling mats to arrest the dust and fly rock will be adopted. Hence, the impact dueto ground vibration will be significantly reduced.

4.9.1 Vibration Abatement

The blasting operations are proposed to use deep hole drilling and blasting usingdelay detonators which are bound to reduce the ground vibrations. Further, theground vibrations will be controlled by using modern shock tubes with delay non-electric (nonel) detonators. The following mitigation measures should continue to bepracticed.

State of the art technology of non-electric initiation system; Free face is kept sufficiently long and care is taken to ensure that effective

burden is not excessive; Firing of maximum number of blast holes towards free face will be carried out; Number of blast holes per delay will be kept as one; Proper stemming of holes will always be carried out; Blasting will be avoided during foggy wealth and when wind velocity is more than

25 km/hour; Blasting will be performed strictly as per the guidelines specified under blasting

technology; Overcharging will be avoided; Blasting operations will be carried out only during day time as per mine safety

guidelines; A safe distance of about 500 m from center of blasting will be maintained; During blasting, other activities in the immediate vicinity will be temporarily

stopped; Drilling parameters like over burden, depth, diameter and spacing will be

properly designed to give proper blast; The mesh ratio S/B will always be more than unity; S/B >1 S = hole spacing, B = distance between rows (burden); Effective stemming of the explosives will be done in the drill holes;


IV-28

The explosives will be selected such that they have:

A high velocity of detonation; A density suited to its particular application; Good fume characteristics; Good water resistance; and Good storage qualities and resistance to atmospheric parameters.

Further, the afforestation programme will reduce the noise and vibration level. A 50m wide belt of trees of increasing height will be provided, which act as an acousticbarrier and reduces noise levels by 20-30 decibel.

In order to reduce ground vibrations caused by blasting the following additionalprecautions will be taken:

a) To provide proper free face to each hole to keep maximum charge per delaywithin limit, holes will be blasted with a combination of short delay detonatorsand sequential blasting machine;

b) To minimize vibration level, burden of first row as well as effective burden forother holes will be kept optimum;

c) Holes will be drilled at 10 degree inclination from vertical so more explosiveenergy is utilized in productive way as in vertical hole only 50% of energy isutilized in productive way;

d) Holes will be charged with proper quantity of explosives instead of excessivecharging;

e) Keep coupling ratio (ratio of charge diameter to hole diameter) minimum forhigh strength booster explosives;

f) Larger column of hole will be charged with low-density explosives i.e., ANFO etcinstead of high-density explosives column to reduce loading density;

g) Total number of holes per blast will be designed properly;h) Blasts will be only once or twice a week; andi) Peak particle velocity will be according to vibration study.

4.10 Greenbelt and Plantation

Proposed Plantation at the Mine Site

The main aim of plantation in the mined out areas is to stabilize the land to protect itfrom rain and wind erosion. The plantation scheme broadly covers the followingareas:


IV-29

Greenbelt around peripheral portions of the ML; and Afforestation on top soil dumps and either sides of the haul roads.

Full fledged horticulture department under the guidance of the experiencedhorticulturist will carry out the Greenbelt development programme.

Plantation will be raised in the 7.5 m wide green belt in the safety zone around themining lease by planting the native species around ML area, backfilled and reclaimedarea, around water body, roads etc. in consultation with the local DFO/Agriculturedepartment. The density of the trees will be around 2500 plants per ha.

Greenbelt Development in ML area

It is given immense importance to develop green cover in ML area. About 0.0100 haof land will be brought under green cover development in first five years ofoperation. Area available for afforestation and green belt in mine lease at the end ofmine life is 0.2000 ha in addition to 19.5512 ha of backfilled and reclaimed withplantation area.

It is also proposed to develop wide Greenbelt around peripheral portions of the ML,afforestation on top soil dumps and either side of the haul roads.

Plantation Species

The suggested species for plantation are given in Table-4.9. The plantation species isconsidered based on the following:

Adoption to the geo-climatic conditions of the area; Mix of round, spreading, oblong and conical canopies; Different heights ranging from 4 m to 20 m; Preferably evergreen trees; Fast growing type; A thick canopy cover; Preferably of native origin; and Having large leaf area index.

4.11 Biological Environment

There are few forest patches and reserved and protected forests in study area.Marine National Park is about 4.12km, Marine Sanctuary is about 0.521km & GagaBird Sanctuary about 16.55km of the study area.No loss of forest resource is envisaged due to the project. The impacts on flora arebriefly described in the following sections:

4.11.1 Impact on Terrestrial Ecology

Flora


IV-31

There is no forest area in the core zone, although there are few reserved andprotected forests in the buffer zone. As the mining activity is in the core zone noimpact on the flora of the buffer zone due to the proposed mining of bauxite isanticipated.

The impact on terrestrial ecology will be due to emission of gaseous pollutant likeNOx. The pollutant at a very low dose acts as an atmospheric fertilizer for thevegetation. However, at higher doses, they are injurious to both vegetation as wellas animals.

Extensive plantation comprising of pollutant resistant trees is undertaken, which willserve not only as pollution sink but also as a noise barrier. It is expected that with theadoption of these mitigatory measures, the impact due to operation of the mine willbe minimal on the terrestrial ecosystem.

Fauna

The adverse impacts on fauna would be mainly due to:

Human activity; Noise; and Land Degradation.

The impact on the fauna of the buffer zone due to the mining activity will bemarginal as minimum disturbance will be there outside the mine lease area. Theproposed progressive mine closure, plantation and pollution prevention and controlover a period of time will create conditions favourable for fauna.

4.11.2 Impact on Aquatic Ecology

No wastewater generation is envisaged from the mining operations. The domesticsewage is sent to septic tank followed by soak pit. The rainwater and seepage watercollected in the sumps will be re-used for dust suppression and for greenbelt. Hence,no impact is envisaged from the mining operations on aquatic bodies.

4.11.3 Mitigation Measures

No impact is envisaged on biological environment of the area. However, extensivegreenbelt / green cover will be developed in and around ML area.


IV-32

4.12 Occupational Health (Impacts and Mitigation Measures)

5.0 ANALYSIS OF ALTERNATIVE TECHNOLOGY AND SITE

5.1 Site Alternatives under Consideration

No alternative mining method has been proposed.

The mining projects are site specific as such alternate sites is not considered.

5.2 Analysis of Alternative Technology

5.2.1 Choice of Method of Mining

Factors in the choice of an actual mining method for a given deposit are depositcharacteristics, percentage recovery, requirement of health and safety andenvironmental concerns, production, scheduling scope of mechanization andautomation, workforce requirements wage rates, land reclamation, operating andcapital cost estimates. The selection of the mining method (development andextraction) is a key decision to be made in the opening up of a mine.

Surface or open pit mining is used for large, near-surface deposits is drilled, blasted,loaded into trucks, and hauled to a facility where it is crushed and ground to auniform size for further processing. Surface mining requires the removal and disposalof layers of top soil and underlying rock commonly called the overburden. The ore isbroken into pieces that can be easily transported and moved to a crushing plant forfurther processing. Mining must be planned so that the combine of miningprocessing and reclaiming the land is taken up concurrently.

The Semi Mechanised opencast mining method will be adopted because of thefollowing reasons:

The Semi Mechanised opencast mining operations ensure higher mineralconservation.

The method used for mining is efficient for Bauxite mining, so no alternative miningmethod has been proposed.

7.0.2 Conclusion on Public Hearing

As there is no further representation from the Public present during public hearing,

P.U. Dave Regional Officer, GPCB Jamnagar summed up the Proceedings of the

Public hearing and declared the Public Hearing as over. The details of people

attended, representations received in writing during the public hearing are enclosed

along with the minutes of the public hearing as Annexure XIII.

7.1 Risk Assessment & Occupational Health & Safety and Disaster Management

Mining by open cast method involves dust generation by excavation, loading and

transportation of mineral. At site, during blasting, excavation and loading activity,

dust is main pollutant which affects the health of workers whereas environmental and

climatic conditions also generate the health problems.

Addressing the occupational health hazard means gaining an understanding of the

source (its location and magnitude or concentration), identifying an exposure pathway

(e.g. a means to get it in contact with someone), and determination of likely a receptor

(someone receiving the stuff that is migrating).

Occupational hazard due to mining mainly comes under the physical hazards.

Possible physical hazards are as below mentioned:-

7.1.1 Physical Hazards due to Mining Operations:

Following health and safety related physical hazards were identified due to mining

operations to the workers:-

1. Light: - The workers may be exposed to the risk of poor illumination during

evening hours or excessive brightness during day times. The effects are eye strain,

headache, eye pain and lachrymation, congestion around the cornea and eye fatigue.

2. Heat and Humidity: - The most common physical hazard is heat as working is

done in open sun light without any shed. The direct effects of excessive heat exposure


VII-13

in summer season areas are burns, heat exhaustion, heat stroke and heat cramps; the

indirect effects are decreased efficiency, increased fatigue and enhanced accident

rates. Heat and humidity are encountered in hot and humid condition when

temperatures and air temperatures may exceed 480C in the mining area.

3. Eye Irritation: - During the high windy days in summer the sandstorms could be

the problems for eyes like itching and watering of eyes.

4. Respiratory Problems: - Large amounts of dust in air with possibility to have free

crystalline quartz can be a health hazard, exacerbating respiratory disorders such as

asthma and irritating the lungs and bronchial passages. However, this can be easily

controlled by water sprinkling.

5. Noise Induced Hearing Loss: - Vehicles and Machinery is the main source of noise

pollution at the mine site, though they are not significant

6. Insect and snake bites: These are possible as their habitations below boulders, if

any, may be disturbed during mining.

7. Approaching areas having deep pits unknowingly: These are possible if there is

any such site nearby and no warning sign boards are provided.

Safety in the workplace is critical to the success of running a business, no matter what size it

is. As a small business owner one has certain rights and responsibilities regarding health and

safety in the workplace. Even without any employees, one must ensure that the business does

not create health and safety problems for the customers and the general public.

All safety gears will be provided to workers and care will be taken by the Management that

these are used properly by them. All safety norms will be followed.

The Management, however small it may be, will form a policy and methods to execute them

as given in Fig. 7.1.


VII-14

Fig. 7.1: Occupational Health – Policy and Methods

7.2 Occupational Health – Proposal for Surveillance

The choice and the implementation of specific measures for preventing workplace injury and

ill health in the work-force of the proposed mining project are due to operations like blasting,

excavation, mining machineries, loading and transportation of materials in open areas without

any shed and exposure to unexpected and natural weather conditions. Below are the most

common causes of injury and illness in the mining industry:

Slips, trips and falls on the same level, falls into pits, unguarded machinery, falling

objects while loading;

Moving machinery, on-site transport, loaders and trucks/dumpers;

Exposure to uncontrolled solar heat, exposure to minerals and inhalable agents (fine

dusts );

Manual handling and repetitive work;

Lack of OSH training, poor work organization;


VII-15

Inadequate accident prevention and inspection, inadequate emergency first-aid and

rescue facilities, lack of medical facilities and social protection;

Mining industry generates dust during its operation and transportation. Dust may enter

into the systemic circulation and thereby reach the essentially all the organs of body

and affects the different tissues.

Continuous working and improper working position leading to pain & exhaustion.

7.2.1 The OHS system:

The entire OHS system will be designed as per Fig. 7.2.

Fig. 7.2: OHS system

7.2.2 Personal Protective Equipment (PPE)

General Provisions

As a supplementary protection against exposure to hazardous conditions in the mining

projects where the safety of workers cannot be ensured by other means, such as eliminating

the hazard, controlling the risk at source or minimizing the risk; suitable and sufficient PPEs,

having regard to the type of work and risks, and in consultation with workers and their


VII-16

representatives, shall be procured and used by the workers and provided and maintained by

the employer, without cost to the workers.

Items of PPE provided shall comply with the relevant BIS standards and criteria

approved or recognized by the competent authority. Where BIS standards are not

available, PPEs meeting international standards may be procured.

Those responsible for the management and operation of the personal protection

programme shall be trained in the selection of the proper equipment, in assuring that

it is correctly fitted to the people who use it, in the nature of the hazards the

equipment is intended to protect against, and provide adequate comfort, and in the

consequences of poor performance or equipment failure.

PPEs shall be selected considering the characteristics of the wearer and additional

physiological load or other harmful effects caused by the PPEs. It shall be used,

maintained, stored and replaced in accordance with the standards or guidance for

each hazard identified at the facility and according to the information given by the

manufacturer.

PPEs shall be examined periodically to ensure that it is in good condition.

Different PPEs & their components shall be compatible with each other when worn

together.

It shall be ensured that the procured PPEs are ergonomically designed and, to the

extent practicable, should not restrict the user’s mobility or field of vision, hearing or

other sensory functions.

Employer shall ensure that the workers who are required to wear PPEs are fully

informed of the requirements and of the reasons for them, and are given adequate

training in the selection, wearing, maintenance and storage of this equipment.

When workers have been informed accordingly, they shall use the equipment

provided throughout the time they may be exposed to the risk that requires the use of

PPEs for protection.

The PPEs shall not be used for longer than the time indicated by the manufacturer.


VII-17

Workers shall make proper use of the PPEs provided, and maintain it in good

condition, consistent with their training and be provided with the proper means for

doing so.

PPEs procured shall not contain hazardous substances, such as asbestos.

7.2.3 Head Protection:

Helmets intended for use in industry shall be subjected to a test for resistance to

falling objects while loading.

Any helmet that has been submitted to a heavy blow, even if there are no evident

signs of damage, shall be discarded.

If splits or cracks appear, or if a helmet shows signs of ageing or deterioration of the

harness, the helmet shall be discarded.

Helmets for persons working overhead shall be so procured that they shall be

provided with chin straps.

In addition to safety, consideration shall also be given to the physiological aspects of

comfort for the wearer.

The helmets shall be so procured that they shall be as light as possible, the harness

should be flexible and should not irritate or injure the wearer and a sweatband should

be incorporated.

All protective headgear shall be cleaned and checked regularly.

7.2.4 Face & Eye Protection:

Face shields or eye protectors shall be used to protect against flying particles and dust

storms.

Goggles, helmets or shields that give maximum eye protection shall be worn by

operators and their helpers.

With the use of face and eye protectors, due attention shall be paid to greater comfort

and efficiency in consultation with workers.

The protectors shall be fitted and adjusted by a person who has received training in

this task.


VII-18

7.2.5 Respiratory Protective Equipment:

When effective engineering controls are not feasible, or while they are being

implemented or evaluated, masks, appropriate to the hazard and risk in question, shall

be used to protect the health of the worker working in dusty conditions.

7.2.6 Hearing Protection:

Noise pollution is not a major issue in the project except while working near a

blasting site and noisy mining machinery. However, the following measures shall be

taken if anybody is to work in a noisy area:

When effective engineering controls are not feasible or while they are being

implemented or evaluated, hearing protection shall be used to protect the health of

workers.

Hearing loss of speech frequencies may occur with elevated long-term exposure to

noise. The use of hearing protectors gives the best results to users who are well

informed of the risks and trained in their use. If earplugs are used, special attention

shall be paid to the proper fitting technique.

Hearing protectors shall be so procured that they are comfortable, and the users shall

be trained to use them properly. Special attention shall be paid to possible increased

risk of accidents due to the use of hearing protectors. Earmuffs reduce the capacity to

locate sound sources and prevent warning signals from being heard. This is especially

true for workers with considerable hearing loss.

No model is suitable for all persons. Those wearing hearing protectors shall be able to

choose from alternative products that meet the attenuation criteria. Earplugs shall not

be the only solution as not all people can wear them.

Hearing protectors shall be evaluated through an audiometric test programme for

exposed workers.

7.2.7 Protection from fall:

In mining projects, workers are exposed to working at uneven sites with pits and

slopes not properly designed.


VII-19

Devices like fencings and warning signboards shall be provided to prevent workers

from falling to the extent possible.

Appropriate and timely rescue shall be provided.

7.2.8 Protection from flying rock and blast vibration:

Though the blasting will be controlled and only to loosen the rock, flying rock

elements may reach habitations and injure persons.

Blasting will be done on schedule times with proper information by public

announcement system to warn workers and nearby villagers.

The area to be blasted will be fenced temporarily.

Charge amount and delay per charge will be controlled to limit vibration within CMRI

limits and USBM Model will be run to predict peak particle velocity (ppv) and safe

distance from blasting site where ppv will be within limits.

7.4 Disaster Management Plan

7.4.1 Introduction

Even with all precautions, disasters may take place. As such, an Emergency Plan has been

formulated to take care of any disaster in the project and surrounding areas and is detailed

here.

In order to prevent occurrence of any disaster, the project will be provided with

various safety measures as described. However, in case of failure of safety measures or due

to natural calamity or sabotage, disaster may happen. Therefore, it is necessary to provide

disaster control facilities to minimize losses due to disaster. Normally, in the project, no

major disaster affecting nearby population areas are foreseen. However, accidents inside

the project affecting workplace in vicinity cannot be ruled out.

7.4.2 Definition of disasters

A situation will be called a `Disaster' if it entails any one or more of the following factors:

Risks of loss of human lives - ten or more in one single situation.

Loss of property as a consequence of the incident is over Rs.1 Crore and/or bears a

potential to the above.


VII-22

A situation which goes beyond the control of the available resource of the project.

A situation apparently may not have much loss but its long-term severity can affect

loss of life, production and property.

7.4.3 Type of disasters:

The types of possible disaster in the project are given below:

i) Disaster due to failure of safety measures on account of:

- Fire and explosion

- Pressure wave transmission due to blasting or explosion

- Collapse of mine wall and dump slope

- Accidents due to mining equipment and trucks/dumpers

ii) Disaster due to natural calamity on account of:

- Flood

- Earth quake / cyclone / Storm / Cloud burst / Lightning

iii) Disaster due to external factors on account of:

- Food poisoning / Water poisoning

- Sabotage

- Quick sand conditions

7.4.4 Objectives:

Objectives of the disaster control/management plan for the proposed project are:

i. To identify type of major disasters that may occur in the project.

ii. To collect data on type of disasters, which had happened already in other mining projects.

iii. An action plan to handle disaster.

7.4.5 Identification of Hazardous Process/Area: The entire area is prone to hazard.

7.4.6 Level of Accident:

If there is any disaster in any part of the project /work place due to any reason, the area which

may be affected can be classified in the following four classes:


VII-23

1. Level I - Operator level

2. Level II - Local/community level

3. Level III - Regional/ national level

4. Level IV - International level

Level I class of accidents have been considered for the project.

Level I

Under this level, disasters may happen due to fire and explosion, accidents due to traffic, falls

on uneven areas and pits, toxic gas release, pressure wave transmission due to blasting or

explosion, flash floods, inundation, cyclones, cloud burst, collapse of dumps and earthquake.

This level has probability of occurrence affecting persons inside the project site-may be

workers or any visitor including stray animals who have strayed into the site as the site has no

protective boundary of its own due to its nature unlike an industrial plant. Moreover, as the

project, other than controlled blasting, has no source of fire, explosion, or toxic gas release,

the effect will not reach nearby community.

7.5 Major Hazards and their Control:

Fire and Explosions:

The mining machineries use diesel and these may be stored at site. The fuel oil storage areas

may face fire and explosion problems if the Hazardous Materials Act is not complied with.

Fire protection facilities will be provided as mentioned under Disaster Control Team

responsibilities to handle Fire and explosion.

Fall in pits:

The entire work area is unprotected worked out area. The levels are not uniform having pits

and slopes. There are every possibility of workers, visitors and stray cattle to fall in pits.

Fencing will be provided wherever is practicable as complete fencing of pits is not

practicable.

Failure of Pit Slope

Pit will be created of limited depth with bench heights not exceeding 3m and a slope of 450.

Thus the chance disaster during collapse of pits or failure of pit slope is under control.


VII-24

Failure of Waste Dump

Rolling of stones from dump may pose severe chances of injury. However, as all dumps will

have adequate slope, chances are minimized. However, bund walls of 3m height will be

created around dumps to catch rolling objects. Also, during heavy rains, dump slide may take

place which will be contained by these bund walls.

Explosion, Fire

The operation needs only controlled blasting and hence any major fire or explosion disaster is

not anticipated.

Accidents from Trucks/Dumpers

Movement of trucks and dumpers inside the lease area and accident during loading and

transportation of minerals/overburden may cause accidents.

Measures to Prevent Accidents Due to Trucks/Dumpers

All transportation within applied mining lease working shall be carried out directly under

the supervision and control of the management.

The vehicles will be maintained in good condition and checked thoroughly and vehicles

without fitness certificate or PUC Certificate will not be allowed. In case of doubt, vehicles

will be inspected by a competent person authorized for the purpose by the management.

Road signs will be provided along the evacuation route showing maximum speed limit,

school sites, market places, hospital sites or any other sites where crowds are anticipated en

route and at each and every turning point up to the main road (wherever required).

To avoid danger while reversing the equipment’s/ vehicles especially at the working place /

loading points, stopper shall be posted to properly guide reversing/ spotting operating,

otherwise no person shall be allowed within 10 m radius of machine except operators.

Flash Floods:

As the project site has many deep pits, it has probability of getting affected by flash floods in

case of excessive rains, if the workers remain uninformed. They may be severely affected

leading to wash away in the stream.

Insect and Snake Bites:


VII-25

The area of mining is broken areas and pits having good habitation of benthic organisms,

insects and snakes. During working, they may feel disturbed and there are possibilities of

insect and snake bites. Anti venom injections will be kept at site and at contracted hospitals

nearby and this will be administered only by a qualified doctor as mentioned in the Disaster

Control Team responsibilities.

7.6 Disaster Preventive Measures

Alarm System – an effective control system:

In case of mining projects, where maximum chances of disaster are due to uninformed

blasting, flash floods and inundation due to anthropogenic or natural activities, a proper

communication and alarm system is the first requirement. The alarm system can be activated

during each disaster as per the protocol and for natural calamities like heavy rain or flood in

the adjoining river, if any, only if the Safety Officer is communicated the same from upstream

sources on time. There is a time lag between the occurrence of the situation at source and it’s

reaching the site, which are some distance away. If the source is due to anthropogenic

reasons, the information must be communicated to downstream areas so that they can take

preventive measures on time. In case the source is due to natural disasters, then also its effect

will take some time to reach the project site and there is sufficient time to take preventive

actions. To develop and operate such a communication system during natural calamities is the

responsibility of the state government. The responsibility of the project is to develop links

with nearby villagers to warn them before blasting and the state government, specially the

irrigation department during flash floods, so that they can receive such communications on

time and translate into actions. The project shall develop its own communication and alarm

system which will work as follows:

Whereas for blasting, the alarm will be initiated as per protocol and during flash floods, on

receiving the message of `Disaster’ from upstream sources, the Safety Executive, will instruct

Commanding Officer Security services to sound SIREN WAILING TYPE FOR 5

MINUTES. On receiving the message of “Emergency Over” from Safety Executive All Clear

Signal by Sounding Siren straight for two minutes will be given. The features of the alarm


VII-26

system will be explained to one and all to avoid panic or misunderstanding during disaster.

7.6.1 Project layout:

Provision of adequate access ways for the movement of equipment and personnel are

kept.

Minimum two numbers of escape routes for escape during disaster shall be identified

and informed.

Siting of fuel oil storage for mining machineries, if any, shall be in protected fenced

area inside tank bund located on the shore and not in river bed.

7.6.2 Fire Fighting

The proposed project will be provided with fire protection systems as given in Table 7.2.

Table 7.2: List of Fire Extinguishers Required at Different Locations

Name of site Type

Fuel Tank Area CO 2 Foam type

Dry Chemical type

Sand Baskets

In project office Dry Chemical powder type

However, prior to installation of fire station & safety equipment, an experienced and

qualified Fire Officer as per Factories Act will be engaged to carry out in-depth study and

advise on the selection of equipment.

7.6.3 Safety

The proposed project will have a Safety Executive who will be an experienced and qualified

staff whose main job will be to bring about safety consciousness amongst the work force in

the project. The Safety Executive will conduct regular safety awareness courses/drills by

organizing training of the personnel among the various working levels.

Safety awareness will also be created by the various posters highlighting the safe working


VII-27

practices in working area, public places and roads etc. Report will be given to Management

for corrective measures to improve the safety conditions.

7.6.4 Training

Management will arrange training on safety accident prevention, first aid, hazard control,

housekeeping and environmental management. Special emphasis with mock drills in disaster

control will also be planned.

7.6.5 Communication

In the proposed project, there will be up-to-date communication facilities with

telecommunication and mobile phones, walkie-talkies, loud speakers to warn workers in case

of an accident.

Contingency Plan and formation of Disaster Control Team

The contingency plan has been prepared from the experiences of accidents that have occurred

in various other mining projects. The contingency plan being a dynamic plan will need

periodical reviews and modifications with new experiences. Even with all precautionary

measures taken to avoid disaster, disaster may occur. To tackle situations during and after

disaster, a well-defined contingency plan and persons responsible to execute it is a must. The

management will form a Disaster Control Team which will be headed by a Safety Executive,

who is a senior full time employee of the company well qualified in Risk Management and

Safety. The Safety Executive will be made responsible to handle disaster. On getting

information about any accident, the officer will perform the following tasks:

verify from the affected project site

Inform the Management or other nominated coordinators immediately.

To be responsible for planning and provisions of assistance from local authorities.


VII-28

To keep higher authorities informed about the situation.

The decision of the Safety Executive on any matter to meet the objective of disaster

control plan will be final.

To identify persons from within the organization or outside local persons and form a

Disaster Control Team.

To convey message to his Disaster Control Team after consulting Management.

Disaster Control Team will report to the Safety Executive and will consists of

members from Casualty services, Rescue services, Fire fighting services, Traffic

control, Training services, Depot and Transport services, Supply Services, Salvage

service, Welfare services, Security services and Public Relation Service.

All the services will be headed by respective Commanding Officers.

To consult between themselves on matters related to more than one service and to

decide on the action to be taken.

In effect, it is to optimize operational efficiency to rescue rehabilitation and render

medical help and to restore normalcy.

Emergency Organization

It is recommended to setup an Emergency Organization. A senior executive (Mine

Manager) who has control over the affairs of the mine will be heading the Emergency

Organization. He will be designated as Site Controller. As per the General Organization

chart, in the mines, the Mines Manager will be designated as the Incident Controller.

The Incident Controller will be reporting to the Site Controller.

Each Incident Controller, for himself, organizes a team responsible for controlling the

incidence with the personnel under his control. Shift In-charge will be the reporting

officer, who will bring the incidence to the notice of the Incidence Controller and Site

Controller.


VII-29

Emergency Co-coordinators’ will be appointed who will undertake the responsibilities

like fire fighting, rescue, rehabilitation, transport and provide essential and support

services. For this purposes, Security In-charge, Personnel Department, Essential services

personnel will be engaged. All these personnel will be designated as key personnel.

In each shift, electrical supervisor, electrical fitters, pump house in-charge and other

maintenance staff will be drafted for emergency operations. In the event of power or

communication system failure, some of staff members in the mine offices will be drafted

and their services will be utilized as messengers for quick passing of communications.

All these personnel will be declared as essential personnel.

Emergency Communication

Whoever notices an emergency situation such as fire, growth of fire etc will inform his

immediate superior and Emergency Control Center. The person on duty in the

Emergency Control Center will appraise the Site Controller. Site Controller verifies the

situation from the Incident Controller of that area or the Shift In-charge and takes a

decision about an impending On Site Emergency. This will be communicated to all the

Incident Controllers, Emergency Co-ordinators. Simultaneously, the emergency warning

system will be activated on the instructions of the Site Controller.

7.6.6 Emergency Facilities

7.11 Socio – Economic Impact Assessment of virpur Gunawali Bauxite Mining Project,Jamnagar, Gujarat:

IntroductionIn this section of the EIA Report an attempt has been made to assess the Socio-Economic

Impact of the proposed Bauxite Mining Project at village Virpur, Taluka Kalyanpur, District

Devbhumi Dwarka, Gujarat.

Socio-Economic Impact Assessment (SEIA) refers to the systematic analysis of various social

and economic characteristics of the human beings living in a given geographical area during

the period of study. The geographical area is called Study Area or Impact Area. SEIA is


VII-40

carried out separately but concurrently with Environment Impact Assessment (EIA). The

study area consists of core area where the project is located and a buffer area encircling the

project area with a radius of 10 km from the periphery of the core area. The Socio-

Economic Impact Assessment focuses on the likely effect of the project on social and

economic well-being of the community. The impact may be direct or indirect, positive or

negative.

Objective of the StudyThe Socio-Economic Impact Assessment focuses the effect of the project on social and

economic well-being of the community. The above analysis relies on both quantitative and

qualitative measures of impacts. The impacts are evaluated in terms of changes in

community demographics, housing, employment & income, market effects, public services,

retail business, quality of life and artistic qualities of the community. Qualitative assessment

of community perceptions about development is also an important measure of

development impacts. Assessing proposed developments in socio-economic context will

help the community leaders and local people identify potential social equity issues,

evaluate the adequacy of social services and determine whether the project has adverse

effects on overall social well-being.

Scope of the Study

The scope of the study is as follows:

To collect Baseline Data of the study area.

To comprehend Socio-economic status of the people living in the study area.

To assess probable impact of the project on social and economic aspects in the study

area.

To evaluate the likely impact of the project on Quality of Life of the people living in

the study area.

To ensure sustainability of the positive impact.


VII-41

To suggest mitigation measures and agency responsible for taking action in case of

adverse impact.

Methodology

For Socio-Economic Impact Assessment of the proposed project, GRC India carries out

systematic analysis of the various socio-economic characteristics, both in terms of quality

and quantity. Accordingly, both qualitative and quantitative data was collected from

secondary sources. The secondary data was collected from the published data/information

of the Census Authority. Records of the state and district administration were also referred

to.

For collection of primary data, a sample survey was conducted in the study area. In each

selected habitation, a specified number of representative households were selected

scientifically for collection of information through face to face interviews with head of the

household or any responsible member of the family.

Census-cum-Sample Survey in the Core Area

As the likely impact of the project will be greatest in the core area and it diminishes

progressively when move away from the core area to the periphery of the study area, a

Census-cum-Sample Survey was conducted in the core area for the collection of socio-

economic data. It is treated as a census survey because all the habitations located in the

core area were surveyed for the collection of information. Further, in each habitation a

household survey was conducted by drawing representative samples from a list of

households prepared. Since, collection of information from all the households in a

habitation is time consuming and expensive, the sample survey approach was adopted for

collection of information from the selected households in the village(s).

Sample Survey in the Buffer Area

In the buffer area, where the impact of the project progressively reduces with the distance

from the project area, two stage sample design was adopted. The first stage units were

census village(s) and the ultimate stage units were households.


VII-42

Sample Design

Two-Stage Sampling Design was adopted in the study area. The First Stage Units were Census

village(s) and the Ultimate Stage Units were households in the selected village(s).

Method of selection of First Stage Units:

Probability Proportional to Size without Replacement (PPSWOR) was adopted to select the

habitations from the list of Census villages.

Method of selection of Ultimate Stage Unit:

The Circular Systematic Sampling was adopted in each habitation to select the households from

a list of households prepared after complete listing. The household were selected at an interval

(K) calculated by dividing the population (N) by sample size (n).

Sample Size

The sample size at each level (village and household) was decided by using the formula =

√ {(1.96 *σ)/Δ}; where = Sample Size, 1.96 is the Table Value of Confidence Limit, σ =

Standard Deviation and Δ = Degree of Precision.

Survey Instruments

The following Schedules/Questionnaires were developed for collection of Primary Data:

Questionnaire 1: Village Particulars

The village Questionnaire was developed for collection of village particulars like

Demographic details of the village, Infrastructure and other facilities available in the village

from the Sarpanch or other village officials.

Questionnaire 2: Household Particulars

The Household Questionnaire was developed to collect information on various parameters

from the selected households.

Each Schedule/Questionnaire is divided into several blocks and there are both open-ended

and closed-ended questions.

Chronology of various steps to prepare the SEIA Report is as under:


VII-43

Study Area

The project site is located at village Virpur, Taluka Kalyanpur, District Devbhoomi Dwarka

Gujarat. In the study area, there are only nine identified habitations. All habitations are

falling under rural category. The habitations are spread over in different taluka namely

Okhamandal, Kalyanpur, Khambhalia and Kalavad of the district Jamnagar.

The land use pattern of the study area is presented in the table below:


VII-44

It may be seen from the above table that 55.8 per cent of the total geographical area is

cultivable land whereas 15.0 per cent is forest land, 9.0 per cent is cultivable waste land and

the remaining 20.2 per cent is barren or fallow land. Of the total cultivable land, 23.8 per

cent is irrigated land and the remaining 76.2 per cent is un-irrigated land.

Socio-Economic Impact Assessment of the Project

Impact on Demographic Composition:

The impact of the proposed mining project on demographic composition will be marginal as

there will be no major immigration of people from distant areas and mainly local people will

be recruited for employment. The migrants from distant places will be kept bare minimum.


VII-48

Hence, there will be no significant impact on the population composition in the study area.

After expansion of the existing unit the increase in population will be marginal. Since there

will be no significant change in population, the overall sex ratio will remain more or less

same.

Impact on Employment Opportunities:

The greatest impact of the proposed project is employment opportunities for the local

people. The proposed project will provide employment to the local people up to the

maximum extent. It has estimated that 65 people will get direct employment in this mining

project. Besides the above the project is expected to generate some indirect employment

also. Creation of employment opportunities is a positive impact of the project on socio-

economic aspects of people living in the study area.

Impact on Agriculture:

No negative impact on agricultural production in the study area is anticipated due to mining

activities of the proposed project. The lease area is a plateau and there is no vegetation.

Hence no agriculture is possible in the lease area due to its barrenness, pits and quarries.

Impact on Industrial Activity:

The Industrial activity in the study area is expected to get a boost due to proposed mining

project. It is expected that in the near future few micro and small scale industrial units may

come up in the vicinity offering employment opportunities to many people.

Impact on Road Development:

Movement of trucks and other vehicles to and fro the quarry is expected to increase

substantially. Hence, there is ample scope for road development in and around the mining

areas.

Impact on Consumption Pattern of the Local People:

Increased household income due to employment opportune in the mining operation may

change the consumption pattern of the study area.

Impact on Health:


VII-49

To resolve any kind of health hazard and accident in the mining area there are many safety

guards for the workers. For protection from blasting at the mining place, dust and other

materials it may be made compulsory for all workers to wear helmet, masks and gloves

while working in the mining site. There will also be a well-developed medical unit with

trained MBBS doctors and other medical staffs at the mining site.

Impact on Law & Order:

As local people will be employed to run the quarry, no law & order problem is envisaged. It

is expected that the workers will attend to their duties from their residence and return to

their homes after the day’s work is over. However, to meet any untoward incident one

police post may be set up closed to the project area.

Corporate Social Responsibility

As per the section 135 of the Companies Act, 2013 Corporate Social Responsibility (CSR) is

mandatory part of any development project.

As per the guidelines issued on dated 27th Feb, 2014 (Schedule-VII) by the Ministry of

Corporate Affairs, Government of India the suggested ten major CSR activities by giving

importance to the corporate philosophy with the objective to improve the quality of life

and socio-economic scenario with special attention to the people residing in the study area

are given below:

I. Hunger, Poverty and Malnutrition, Promoting Preventive Health Care and Sanitation

and making available Safe Drinking Water.

II. Promoting Education, including Special Education and Employment Enhancing

Vocation Skills Especially among Children, Women, Elderly, and the Differently-Able

and Livelihood Enhancement Projects.

III. Promoting Gender Equality, Empowering Women, setting up Homes and Hostels for

Women and Orphans, setting up Old Age Homes, Day Care Centers and such other

Facilities for Senior Citizens and measures for Reducing Inequalities faced by Socially

and Economically Backward Groups.


VII-50

IV. Ensuring Environmental Sustainability, Ecological Balance, Protection of Flora and

Fauna, Animal Welfare, Agro-forestry, Conservation of Natural Resources and

Maintaining Quality of Soil, Air and Water.

V. Protection of National Heritage, Art and Culture Including Restoration of Buildings

and sites of Historical Importance and Works of Art, setting up Public Libraries,

Promotion and development of Traditional Arts and Handicrafts.

VI. Measures for the benefit of Armed Forces Veterans, War Widows and their

Dependents

VII. Training to Promote Rural Sports, Nationally Recognized Sports, Paralympics sports

and Olympic sports.

VIII. Contribution to the Prime Minister's National Relief Fund or any other fund set up

by the Central Government for socio-economic development and relief and welfare

of the Scheduled Castes, the Scheduled Tribes, other backward classes, minorities

and women.

IX. Contributions or funds provided to technology incubators located within academic

institutions which are approved by the Central Government.

X. Rural Development Projects.

Based on the above suggested activities by the Government of India, the project proponent

may set out to do the following CSR activities by giving importance to their corporate

philosophy in order to achieve the objective to improve the quality of life and socio-

economic scenario with special attention to the people residing in the study area:

1. In support of Health-

Health Checkups and Medical Camps in the project village and other part of

the study area.

Providing free medicines and medical equipments to the Primary Health

Centers falling under the study area.

2. In support of Education-


VII-51

Spreading the light of Education by providing sponsorship or financial

assistance to underprivileged children and meritorious students

Providing uniforms and books to the school children.

A certain part (5%) of budgetary amount i.e., approximately Rs. 2.40 Lakh of the project has

been decided to spend during next three years after commencement of the project in

support of the above mentioned CSR activities.

The estimated budgetary allocation of the amount for these above activities is given in the

table below:

Table: Fund for the various CSR ActivitiesS. No. Activities Allocation of Fund (Rs.

Lakhs)1. In support of Health 1.20

2. In support of Education 1.20Total 2.40

Conclusion

The implementation of the project will increase employment opportunities to the local

people. The mining operation will not only fetch income to the state exchequer but also

ensure healthy development of bauxite mining in the state of Gujarat. The project will

provide impetus to industrialization of the area. It is likely the intending entrepreneurs will

venture to set up micro and small scale units in the near future making the area a mixed

society, associated with industry, trade and business. With the implementation of the

mining project the occupational pattern of the people in the area will change making more

people engaged in industrial and business activities.

In the study area, there is large scope of improving health and educational facilities. It is

expected that same will improve with opening of the project and promoting the CSR &

other associated industrial & business activities by the project proponent. It can be

expected from the project that it may also give some value addition directly or indirectly in

the field of agriculture and agro-based activities in the study area.


VII-52

The overall impact of the project is expected to be positive for the habitants of the area,

the government and the persons associated with the project.

9.0 ENVIRONMENT MANAGEMENT PLAN

The environmental management plan consists of the set of mitigation, management,

monitoring and institutional measures to be taken during the implementation and operation of

the project, to eliminate adverse environmental impacts or reduce them to acceptable levels.

The present environmental management plan addresses the components of environment,

which are likely to be affected by the different operations in a mine area.

The aims of EMP are:

• Overall conservation of environment.

• Minimization of waste generation and pollution.

• Judicious use of natural resources and water.

• Safety, welfare and good health of the work force and populace.

• Ensure effective operation of all control measures.

• Vigilance against probable disasters and accidents.

• Monitoring of cumulative and long time impacts.

• Ensure effective operation of all control measures.

9.1 Air Quality Management

Emissions due to mineral handling, during mining operations are not much and restricted to

the lease area only. Air pollution is caused mainly due to dust generation added with gaseous

emission from transportation activities along with mining operation like drilling, blasting,

loading, haulage etc.

9.1.1 Control of Fugitive Emissions

• Wet drilling arrangements will be made.

• Use of Personal Protection Equipments (PPE) like dust masks, ear plugs etc. by the

mine workers.

• Rock breaker will be used for breaking over size boulders in order to reduce dust and

noise generation, which otherwise would be generated due to secondary blasting.

• Controlled blasting and optimization of use of explosive energy will help in reducing

the above emissions.


IX-3

• Regular water sprinkling on haul roads & loading points will be carried out.

• Development of green belt/plantation around the lease boundary, roads, dumps etc.

• Ambient Air Quality Monitoring will be conducted on regularly basis to assess the

quality of ambient air.

9.1.2 Prevention and control of Gaseous Pollution

• In mining activities, the sources of gaseous emissions would be blasting

• Blasting of explosive results in the increase of nitrogen oxides, which get diluted by

the wind. Controlled blasting and optimization of use of explosive energy will help in

reducing the above emissions.

• Proper maintenance of machines improves combustion process & makes reduction in

the pollution. Good maintenance and monitoring of fuel and oil will not allow

significant addition in the gaseous emission.

9.2 Noise Pollution Control

9.2.1 Noise Abattement and Control

• Proper maintenance, oiling and greasing of machines at regular intervals will be done

to reduce the generation of noise.

• Adequate silencers will be provided in all the diesel engines.

• Blast holes will not be overcharged.

• Plantation along the sides of approach roads and mine area will be done to minimize

the propagation of noise.

• Personal Protective Equipments (PPE) like earmuffs/earplugs will be provided to all

operators and employees working near mining machineries or at higher noise zone.

• Periodical noise level monitoring will be done.

9.2.2 Protective measures for ground vibrations / fly rocks caused by blasting

• Innovations like shelter plantation would be carried around the mine for minimizing

adverse impact of blasting along with following measures will be adopted at mine to

reduce ground vibration, fly rocks, dust generation, noise generation, etc.

• Overcharging will be avoided;


IX-4

• Supervision of drilling and blasting operations to ensure design blast geometry;

• Blasting operations will be carried out only during day time as per mine safety

guidelines;

• Proper warning signals will be used;

• By optimization of drilling – blasting parameters i.e. burden, spacing, depth of hole,

etc.

• By using Control Blasting

• By avoiding secondary blasting with the help of rock breaker.

9.3 Water Quality Management

Adequate control measures will be adopted to check not only the wash-off from soil erosion

but also uncontrolled flow of mine water.

9.4 Waste Management

9.4.1 Nature of waste: They shall be used for backfilling. The quantum of waste to be

removed is given below:



(2015 – 16 )August 15 to

March 16)




There is soil will be utilized for preparation of protective bund during 5 years and then

or leveling and topping of backfilled area so that plantation can be done on it.


IX-5

9.5 Greenbelt and Plantation:

So far as Afforestation is concerned, saplings will be planted in pits of 50 cm to 40 cm dia

and about 0.5m deep would be dug. Depending upon the type of soil and type of plant

species, listed in this chapter in Table 9.2, the interval between the pits would be kept. The

hole will be filled with mixture of soil and manure fertilizer. Local species will be planted in

the area as per availability. A table showing year wise Afforestation scheduled

It was proposed to plant 150 sampling every year during plan period. The lessee has taken up

Afforestation work.

• Plantation should be done in appropriate alternate rows around the proposed site to

prevent lateral pollution dispersion.

• The trees should maintain regional ecological balance and conform to soil and

hydrological conditions. Indigenous species should be preferred.

9.6 Biological Management Measures

There is a requirement to establish a stable ecosystem with both ecological and economic

returns. Minimization of soil erosion and dust pollution enhances the beauty of the core and

the buffer zone. To achieve this, it is planned to increase plantation activities. The basic

objectives of plantation are as follows:-

Improvement of Soil quality

Quick vegetative cover to check soil erosion

Improvement in mining site stability

Conservation of biological diversity

As dust receptor which likely to produce during mining

9.6.1 Greenbelt Development Plan

Green belt is plantation of trees for reducing the pollution as they absorb both gaseous and

particulate pollutant, thus removing them from atmosphere. Green plants form a surface

capable of absorbing air pollutants and forming sinks for pollutants. It improves the aesthetic

value of local environment. Under present project, green belts and shelter plantation have

been planned with emphasis on creating biodiversity; enhance natural surroundings and

mitigating pollution. The greenbelt development plan aims to overall improvement in the

environmental conditions of the region. The plan with a five-fold objective addresses issues

such as providing sink for air pollutants likely to emitted from the project; enhancing the

forest cover for increasing the biodiversity of the region; providing aesthetic value to the

project area enhancing the ecological equilibrium of the area; and to a large proportion in

combating soil erosion.

Afforestation on degraded forest area, forest protection / conservation will be

carried out every year by the mine owner.

10.3 BASELINE ENVIRONMENTAL STATUS

10.3.1 Soil Quality


X-7

Eight soil samples were collected in and around the mine lease area to assess thepresent soil quality of the region. The pH of the soil indicates that the soil is slightlyto moderately alkaline in nature. The nitrogen, phosphorous, potassiumconcentrations were observed to be in the range of less to more than sufficientcategory.

Based on the results, it is evident that the soils are not contaminated by anypolluting sources.

10.3.2 Meteorology

Meteorological data at the site was monitored during 1st March to 31st May 2015representing winter season. It was observed that the during study period,temperature ranged from 19.10C to 42.20C. During the same period of observations,the relative humidity recorded was ranged from 12% to 79.35% A total of 0.19-mmrainfall was recorded during the study period.

10.3.3 Ambient Air Quality

Ambient Air Quality Monitoring (AAQM) has been carried out at seven locations with afrequency of two days per week for three months during summer season of 2015. Theminimum and maximum concentration of PM10 recorded within the study area was50.5 µg/m3 to 139.4 µg/m3 with the 98th percentile ranging between 63.3 µg/m3 to130.7 µg/m3. The minimum and maximum concentration of SO2 recorded within thestudy area was <5 to 6.8 µg/m3 with the 98th percentile ranging between 6.2 µg/m3to 6.8 µg/m3. The minimum and maximum concentration of NOx recorded withinthe study area was 6.5 µg/m3 to 15.8 µg/m3 with the 98th percentile rangingbetween 12.7 µg/m3 to 15.6 µg/m3. The minimum and maximum concentration ofPM10 recorded within the study area was 50.5 µg/m3 to 139.4 µg/m3 with the 98thpercentile ranging between 63.3 µg/m3 to 130.7 µg/m3.

10.3.4 Water Quality

To assess the physical and chemical properties of water in the region, water samplesfrom seven locations were collected from various water sources around the mine leasearea.

The pH limit fixed for drinking water samples as per IS-10500 Standards is 6.5to 8.5 beyond this range the water will affect the mucus membrane and orwater supply system. During the study period, the pH was varying for ground


X-8

waters from 7.62 to 8.21 & pH was varying for surface waters from 7.7to8.16. The pH values for all the samples collected in the study area duringstudy period were found to be within the limits.

The desirable limit for total dissolved solids as per IS-10500 Standards is 500mg/l where as the permissible limits in absence of alternate source is2000mg/l, beyond this palatability decreases and may cause gastro intestinalirritation. In ground water samples collected from the study area, the totaldissolved solids are varying from 1668 mg/l to 4249 mg/l the TDS of thesamples were below the desirable limit but within the permissible limit of2000 mg/l.

The desirable limit for chlorides is 250 as per IS-10500 Standards where aspermissible limit of the same is 1000 mg/l beyond this limit taste, corrosionand palatability are affected. The chloride level, in ground water samples 550mg/l to 1539 mg/l. & for surface water it is 42 mg/l to 18060 mg/l thechloride samples are within the desirable limits.

The desirable limit as per IS-10500 Standards for hardness is 300 mg/l whereas the permissible limit for the same is 600 mg/l beyond this limitencrustation in water supply structure and adverse effects on domestic usewill be observed. In the ground water samples collected from the study area,the hardness is varying from 410 mg/l to 1388 mg/l.

Fluoride is the other important parameter, which has the desirable limit of1mg/l and permissible limit of 1.5 mg/l. however the optimum content offluoride in the drinking water is 0.6 to 1.5 mg/l. if the fluoride content is lessthan 0.6 mg/l it causes dental carries, above 1.5 mg/l causes flurosis. In theground water samples of study area the fluoride value were in the range of0.7 mg/l to 2.1 & in surface water it varies from 0.6 mg/l to 1.3.

Overall all the samples collected from the study area were found to be fit forconsumption, Most of ground water samples are well within the permissible limits.Most of the heavy metals in all samples are below detectable limits

10.3.5 Noise Levels

Ambient noise levels were measured at seven locations around the proposed minesite. Assessment of night time Leq (Ln) varies from 43.2 to 54.6 dB (A) and thedaytime Leq (Ld) varies from 46.3 to 68.4 dB (A) within the study area.
