3.3 Noise Levels:
The values of noise observed in some of the areas are primarily owing to vehicular traffic and other anthropogenic activities. Assessment of night time Leq (Ln) varies from 40.6 to 54.6 dB dB (A) and the daytime Leq (Ld) varies from 50.4 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.
3.4 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 “D” and can be used for propagation of wildlife and fisheries.
3.5 Soil Characteristics:
The soil samples were collected in the month of May 2015. Soil samples were collected from 5 locations to assess the existing soil conditions representing various land use conditions and geological features and each of these locations were identified randomly from where soil was collected from 30 cm below the surface in the pH of the soil were found to be Neutral (7.24 to 7.89 ). Electrical conductivity (EC) is a measure of the soluble salts and ionic activity in the soil. In the collected soil samples the conductivity ranged from 241-444 µmhos/cm.

11 Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine Executive Summary
Medical facilities, 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, an 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 0.4587 ha area will be developed under plantation.
8.2 Budgets for Environmental Protection SI. Measures Capital cost Annual recurring No. (in Rs.) cost (in Rs.) Proposed Proposed 1 Pollution Control - i) Dust Suppression 80,000 ii) Garland drain & ground 60,000 dump iii) Water reservoir 50,000 2 Pollution Monitoring - i) Air pollution 50,000 ii) Water pollution 50,000 3 Occupational Health 50,000 10,000 4 Green Belt & Afforestation 2,50,000 2,00,000 5 Reclamation of mined out 2,00,000 20,000 area
12 Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine Executive Summary
6 Others (specify) - - Total 5,00,000 5,20,000
8.3 Conclusion Based on the EIA study it is observed that there will be an increase in the dust pollution, 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. 5.0 lakhs as capital cost and Rs 5.2 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.

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 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 (17 % each), Gujarat (4%), 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%).

2.8 Geology
In this as well as in the surrounding areas, both Central and state Geological departments have conducted regional and detailed geological studies. The generalized geological sequence, as worked out by them is as follows:
Recent Soil, blown sand, shell limestone, calcareous clays
Pleistocene Milliolite limestone
L.Miocene ( Gaj series) Concretionary limestone , calcareous clays, greenish bentonic clays, calcareous grit, conglomerate
------Unconformity------Paleocene (Supra Trappeans) laterite with or without bauxite Ocherous and benthonic clays (prominently purple to brown in colour and spotted) Altered derivatives of trap and other pyroclastic etc Eocene Deccan trap The bauxite deposits of kalyanpur taluka are essentially confined to a narrow delta of laterite extending from Mota Asota in the north Gandhvi village in the south west covering a total distance of 30 kms having a width of about 6 km. between Mewasa and Harbardi villages and less than 1 km from Ran, Bhatia and lamba villages. Though the laterite capping is seen up to 60 m. Above MSL the thickness rarely exceeds 7.5 m. The laterite are undertaken by Deccan traps (being source rock of laterite) and overlain by Tertiary sediments. The tertiary rocks are generally seen on the west of the laterite belt. The detailed study of laterite has revealed that they are of two types viz.

1. Hard , deep brown, clay free , ferruginous laterite forming a thin crust on the surface and 2. Soft clay rich with mottled surface and exhibiting pseudo stratification.
The bauxite are confined to the laterite of first type described above. The laterite grades downward gradually to clay zone (lithomarge) exhibiting characteristic purple to red colour. Occasionally white colour is also seen. The purple and red coloured lateritic clays are mottled with the white kaolinitic clays, exhibiting the relict structure of trap from which they have been derived. The bauxite occurs within the lateritic belt either as concentrated pocket or scattered at random within it with erratic variation both horizontally and vertically. Whenever bauxite occurs as pocket, the profile observed as follows, Concretionary mottled zone Nodular zone Compact massive zone Lithomerge The bauxite in this area exhibits typical oolitic or pisolitic habit and colloform structure. The laterite belt, as said above , is characterized by escarpment slope and dip slope, which are gentle in nature. In the entire belt laterite describes above bulk of the high grade bauxite pockets are confined to Mewasa and virpur villages (about 65%). In general, on an average, the thickness of the bauxite zone extends to about 6 m.

2.18 Mining Operation The lessee has been mining bauxite for a long time by mechanized open cast mining method (OTFM) with the use of Excavator and tippers. The position at present in the ML area is that the major part of mineable reserves have been mined out. The present mining has been carried out by forming one bench in bauxite and one bench in topsoil if available in the particular block. Top soil is scraped and stacked over the statutory boundary, which is again spread over backfilled area. The thickness of bauxite zone varies between 3.00m to 6.5m. Drilling is being done by jack hammer and blasting is done by suitable explosive, available in the region. Blasted material after manual sorting is being loaded into trucks. Mining is carried out only during the day shift. The general nature of bauxite is soft and hence, it can be easily mined with the help of excavator. A part of bauxite reserve is of compact nature and require drilling and blasting. Haul roads are maintained properly at a gradient of not less that 1:16. The production capacity of mine is about 4.65 lakh t/annum. The production done during the last five years of the plan period was less than the proposed production because there was poor demand of bauxite in the market. The mining has been done by developing working pits in the area. In general the pits are irregular in shape and slopes 70° from vertical. The dimensions of the pits are as under: Name of the Dimension of Depth in m Lithology Block working pits in m Bock A 125 x 110 0.0 to 6.5 Bauxite (Ghanghra Block) 120 x 30 6.5 to - Lithomargic clay

The depth of pits varies from 3.0m to 6.5m. It is proposed to enhance the production during ensuing five years be at use in earlier days the state government did not issue royalty pass did not gave permission to sell the low grade material but now the state govt. allows to sell the low grade bauxite in the market & lessee has order for low grade bauxite of the area. Hence, the lessee has achieved the proposed production. 2.18.1 Proposed method of mining during mining scheme period:- In the proposed mining scheme, the work will be carried out in all the blocks of the lease area adopting mechanized opencast method (OTFM) with the use of excavator and tipper. Topsoil wherever available will be scraped first separately and stacked near pit or over statutory boundary. Bauxite present in the proposed area has thickness varying between 3.00 to 6.5m and will be mined out by developing one bench of height equal to thickness of bauxite bed. Bauxite available at pit floor will also be excavated with the help of excavator tipper combination. About 30% of ROM requires drilling and blasting which will be carried out with the help of jack hammer and compressor. Controlled blasting practice will adopted and the management intends to eliminate blasting and alternative method for mineral extraction will adopted such as, ripper/ dozer combination/ rock breakers/ surface miners etc and practiced wherever practicable. Blasting will be done by qualified blaster under supervision of mine manager. There is no production of high grade bauxite from the area. Low grade bauxite will be stacked near pit and will be sold to buyers whenever demand arises. The existing fair weathered road will be used as approach road to connect village road.

No backfilling will be done in the area. The waste generated during mine scheme period will be stacked in the mined out area in part of the lease area. As volume of voids (area to be worked) is much more than material available for backfilling, entire mined out area upto original ground level will not be possible. Therefore no backfilling will be done and the mined out area will be developed into water reservoir. ***************

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

3.2 STUDY PERIOD
The baseline environment quality was carried out over a radial distance of 10 km around the mine during pre-monsoon season of 2015 covering the months of March 2015 to May 2015.
3.3 METHODOLOGY / APPROACH 3.3.1 Methodology of EIA Environmental Impact Assessment study has been conducted within an area of 10 km radius around the ML area. The various steps involved in the study for this project are divided into three following phases. • Identification of significant environmental parameters and assessing the baseline status within the study area and assessment of pollutants envisaged due to proposed activities and the polluting activities in the study area on various environmental parameters • Evaluation of impacts after superimposing the predicted pollution load over the baseline condition. • Prepare Environmental Management Plan for mitigation of impacts on environment arising out of the proposed activity
3.3.2 Approach Environmental monitoring in order to establish the baseline environmental status of the 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 sources for socio-economy, demography, meteorology, land use, ecology, etc. • Identify various existing pollution loads due to mining and domestic activities in the buffer zone

Chapter-3 Baseline Environmental Status
• Evaluate the predicted impacts on the various environmental attributes in the study area by using scientifically developed and widely accepted Environmental Impact Assessment (EIA) Methodologies • Preparation of Environmental Management Plan (EMP) outlining the measures for improving the environmental quality Accordingly, field studies were carried out during the study period (March 2015 to May 2015) to establish existing baseline conditions. 3.4 METEOROLOGICAL CONDITIONS Meteorology is the key to understand the air quality. The essential relationship between meteorology and atmospheric dispersion involves the wind in the broadest sense. Wind fluctuations over a very wide range of time, accomplish dispersion and strongly influence other processes associated with them. A meteorological station was set up at the proposed mine premises. Meteorological data was generated during the pre monsoon monitoring period and shown in Table-3.1. The following parameters were recorded at hourly intervals continuously during monitoring period, except rainfall which was recorded on daily basis.

3.5 AIR ENVIRONMENT 3.5.1 Ambient Air Quality The ambient air quality was monitored in the impact area as per MoEF guidelines. The study area represents mostly rural environment. The prime objective of the baseline air quality study was to assess the ambient air quality of the mining lease area. 3.5.2 Methodology Adopted for the Study The baseline status of the ambient air quality has been assessed through a scientifically designed ambient air quality network. The design of monitoring network in the air quality surveillance programme has been based on the following consideration. Meteorological parameters Topography of the study area Representative of regional background air quality for obtaining baseline status Representative of likely impact areas. Ambient Air Quality Monitoring (AAQM) stations were set up at 14 locations with due consideration to the above mentioned points. AAQM locations were selected in downwind and upwind direction of the proposed mining lease area covering core and buffer zones. Monitoring location at 500m in downwind direction is also considered. The details of the ambient air monitoring stations are given in Figure 3.2 and shown in Table-3.3. Ambient air quality monitoring was carried out twice a week with a frequency of 24 hours for 12 weeks during the study period. The common air pollutant namely Particulate Matter-10 (PM10), Sulphur-dioxide (SO2) and
Oxides of Nitrogen (NOX) has been measured through a planned field monitoring. The baseline values of the air pollutants of concern are presented in Tables below statistical parameters like minimum, maximum, average and 98th percentiles have been computed from the observed field data for all sampling stations and are given Table-3.4. These are compared with the standards III-8 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat

Chapter-3 Baseline Environmental Status
3.5.3: Baseline Scenario a) Suspended Particulate Matter (PM10) Suspended particulate matter in general terms is the particulate matter in suspension in ambient air. It includes dust, smoke etc. In general some of the important sources of suspended particulate matter are mines. The following sources of suspended particulate matter in the study area are identified: Emission due to vehicular movement Dust generation from ground or other mining operations The minimum and maximum concentration of PM10 recorded within the study area was 50.1 µg/m3 to 99.7 µg/m3 with the 98th percentile ranging between 63.3 µg/m3 to 98.2 µg/m3. The suspended particulate matter concentration has been found to be comparatively higher at monitoring sites AQ 1, AQ 2, AQ 6 and AQ 11 due to the other village activities going on in the nearby villages. The 24 hourly average values of PM10 were compared with the National Ambient Air Quality Standards (NAAQS) and found that all sampling stations recorded in the study area are within the applicable limits i.e., 100 µg/m3 for SPM in rural areas.
b) Sulphur Dioxide (SO2) Sulphur dioxide gas is an inorganic gaseous pollutant. Sulphur dioxide emissions are expected to be emitted wherever combustion of any fuel containing sulfur takes place. The Sulphur in the fuel will combine with oxygen to form Sulphur dioxide. The following sources of sulfur dioxide in the study area are identified: Emissions from domestic/consumption of fuel (coal, diesel, etc) Emissions from DG sets used by mining activity and local residents Sulphur dioxide in atmosphere can combine with water (moisture) in the air to form sulphuric acid aerosols that can corrode metal surfaces, fabrics and the leaves of plants. Sulfur dioxide is an irritant to the eyes and respiratory

Chapter-3 Baseline Environmental Status system. Excessive exposure to Sulphur dioxide can cause bronchial asthma and other breathing related diseases as it affects the lungs. The minimum and maximum concentration of SO2 recorded within the study area was BDL (<5 µg/m3) to 6.8 µg/m3 with the 98th percentile ranging between 5.8 µg/m3 to 6.8µg/m3. The 24 hourly average values of SO2 were compared with the National Ambient Air Quality Standards (NAAQS) and it was found that all sampling stations recorded values are below the applicable limits 80 µg/m3 for rural areas.
c) Oxides of Nitrogen (NO2) The important sources of oxides of Nitrogen are from utilities and auto exhaust due to vehicular movement in mine lease area. The following sources of oxides of nitrogen in the study area are identified. 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 number of organic compounds to produce all the effects associated with photochemical smog. NOX has inherent ability to produce deleterious effects by themselves like toxicity. It causes asphyxiation when its concentration is great enough to reduce the normal oxygen supply from the air. The minimum and maximum concentration of NOx recorded within the study area was 6.5 µg/m3 to 18.6 µg/m3 with the 98th percentile ranging between 12.5 µg/m3 to 18 µg/m3. The 24 hourly average values of NO2 were compared with the National Ambient Air Quality Standards (NAAQS) and it was found that all sampling stations recorded values are below the applicable limits 80 µg/m3 for rural areas. 3.6 NOISE LEVELS Noise is one of the most undesirable and unwanted by-products of our modern life style.

As per the standard practice, one sample from each station was taken each month in the study period. Sampling was done by standard sampling technique as per the Standard Methods. Necessary precautions were taken for preservation of samples.
3.7.2 Result & Conclusion: The pH limit fixed for drinking water samples as per IS-10500 Standards is 6.5 to 8.5 beyond this range the water will affect the mucus membrane and or water supply system. During the study period, the pH was varying for ground waters from 7.60 to 8.21 & pH was varying for surface waters from 7.7 to 8.2. The pH values for all the samples collected in the study area during study period were found to be within the limits.

The desirable limit for total dissolved solids as per IS-10500 Standards is 500 mg/l whereas the permissible limits in absence of alternate source is 2000mg/l, beyond this palatability decreases and may cause gastro intestinal irritation. In ground water samples collected from the study area, the total dissolved solids are varying from 1474 mg/l to 4477mg/l the TDS of the samples were above the permissible limit of 2000 mg/l. Highest TDS was observed in case of Mewasa. The desirable limit for chlorides is 250 as per IS-10500 Standards whereas permissible limit of the same is 1000 mg/l beyond this limit taste, corrosion and palatability are affected. The chloride level, in ground water samples 480 mg/l to 1539 mg/l. The higher chloride level was found in the ground water samples from villages Mewasa & Kenedy & for surface water it is 42 mg/l to 152 mg/l the chloride samples crossed the desirable limit. The chloride level of 18125 mg/l is observed in Pindara Bay sample due to mixing of sea water. 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 limit encrustation in water supply structure and adverse effects on domestic use will be observed. In the ground water samples collected from the study area, the hardness is varying from 410 mg/l to 1495 mg/l. Fluoride is the other important parameter, which has the desirable limit of 1mg/l and permissible limit of 1.5 mg/l. however the optimum content of fluoride in the drinking water is 0.6 to 1.5 mg/l. if the fluoride content is less than 0.6 mg/l it causes dental carries, above 1.5 mg/l causes flurosis. In the ground water samples of study area the fluoride value were in the range of 0.7 mg/l to 2.1 mg/l & in surface water it varies from 0.6 mg/l to 1.3 mg/l.
The proposed study area is situated near the coastal area. So, the ground water characteristics namely TDS, chloride, fluoride and hardness levels all exceed the desirable and permissible limits as per IS-10500. The ground

Chapter-3 Baseline Environmental Status water is thus classified as brackish to marginal saline. Hence, the ground water of this area is not suitable for drinking. The surface water can be compared with class “D” which is suitable for propagation of wildlife and fisheries. Similarly, ground water is suitable for irrigation of only salt tolerant plants due to high TDS & Chloride content.

3.8.2 Results of Analysis of the Soil Physical characteristics of soil were characterized through specific parameters viz bulk density, porosity, water holding capacity, pH, electrical conductivity and texture. Soil pH plays an important role in the availability of nutrients. Soil microbial activity as well as solubility of metal ions is also dependent on pH. In the study area, variations in the pH of the soil were found to be slightly alkaline (7.24 to 7.89). Electrical conductivity (EC) is a measure of the soluble salts and ionic activity in the soil. In the collected soil samples the conductivity ranged from 241-444 µmhos/cm. The soils with low bulk density have favorable physical condition where as those with high bulk density exhibit poor physical conditions for agriculture crops. The soil is of medium fertility (CEC mostly 10-20) and have favourable characteristics for crops namely idea pH (<8), good texture (sandy clay loam), good SAR (<3) and acceptable EC (< 400 µmhos).
3.9 LAND USE/LAND COVER MAPPING To assess the land use pattern surrounding the 10 km radius of the site, a detailed study was carried out. The land use pattern study reveals that the 10 km environs is predominantly occupied by agricultural land and ocean area in the North.

From the above analysis it is observed that the V/C ratio in case of all the roads in the vicinity of the blocks of Virpur, Mewasa may increase due increase in traffic load with change in the Level of Service from “A” which is “Excellent” on the metalled road of the village joining Virpur, Mewasa and Ran to NH-947 to “B” which is “Very Good”. The total increase in traffic load is proposed to increase on NH-947, thereby changing the LOS to “A” which is “Execellent”. Although the ratios will increase for the vicinity roads near the blocks in Kenedy village, the Level of Service will remain “A” which is “Excellent” on the metalled road of the village which joins Gujarat SH-29. The V/C for SH- 29 was also calculated and analysed that the LOS will remain “A” which is “Excellent”. So the additional load on the carrying capacity of the concerned roads is not likely to have any significant adverse effect.

3.11 BIOLOGICAL ENVIRONMENT 3.11.1. 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,

4.0 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES
4.1 Details of the Investigated Environmental Impacts
This chapter provides a brief overview of the potential impacts on various environmental components due to the proposed opencast mining activities.
The opencast mining operations in general cause environmental degradation and if adequate control measures are not taken to prevent/mitigate the adverse environmental impacts, these operations may cause irreversible damage to the eco- system. The environmental parameters most commonly affected by mining activities are:
Topography and drainage Air quality Water resources and quality; Soil quality; Flora and Fauna; Landuse Pattern; Noise levels and ground vibrations; Socio-Economic conditions; and Occupational Health.
Various environmental impacts, which have been identified due to the mining activities, are discussed in the following sections and mitigation measures are suggested.
4.1.1 Impact on Topography and Drainage
The general topography of the lease area is practically flat with isolated low lying lateritic ridges. The lease area is divided in different blocks in village Virpur, Mewasa, Kenedy and Mota Asota.

A major part of the ML comprises of peneplain relief whose original topography has been mutilated and is now covered by worked pits and waste dumps.
Although no cultivation is being done in the lease hold area, but cultivation is done on agriculture land in rainy season in nearby area. Bajra and Jowar are the main crops of the region, which are grown on the cultivable land in the area.
There is no river or nala within the lease area. No permanent nala is passing in the area. Rainy water flows in eastern direction. The temperature reaches upto 45°C during summer and minimum upto 12°C in the winter.
The waste land of mine lease area will be reclaimed in the form of water reservoir which will be used for rain water harvesting purpose and for recreation and irrigation in adjoining agricultural fields. The water reservoirs will be surrounded by green belt improving aesthetics of the area.
The drainage map of the study area is shown in Figure-4.1.

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 (NO2) 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
IV-4 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures
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 1335 TPD from Virpur, Mewasa, Mota Asota Blocks and 696 TPD from Kenedy Blocks 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 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 will be the main polluting source in the proposed mining activities releasing Particulate Matter (PM10)
IV-5 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures 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. 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

4.2.5 Meteorological parameters
The meteorological data file for the Short Term model normally consists of meteorological data, beginning with 0100 hour of March 1 2015 and ending with 2400 hour of May 31, 2015, the hourly meteorological data recorded continuously at site. 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.

The excess of the 24-hour PM10 standards is observed. The 24-h maximum incremental GLC of PM10 11.3 µg/m3 occurred at the center of the mines blocks at Virpur block and GLC of PM10 4.4 µg/m3 occurred at the center of the mines blocks at Kenedy block. The value of PM10 at the project site was 106.7 µg/m3 and 85.7 µg/m3 observed after superposition of base-line value of 95.4µg/m3 and 81.3 µg/m3 on the incremental GLC of 11.3 µg/m3 and 4.4 µg/m3 respectively, 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 4.3) indicate that 11.3 µg/m3 and 4.4 µg/m3 are predicted to occur from the mining operations of Virpur, Mewasa, Mota Asota and Kenedy blocks. However, at the receptors of 500m downwind from project site the contour of 0.5 µg/m3 and <0.01 µg/m3 has occurred at Virpur, Mewasa, Mota Asota and Kenedy blocks respectively, 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 localized to operations.

4.3 Water Environment
4.3.1 Impact on Water Resources
As pointed out earlier, due to scanty and unpredictable rainfall, there is acute scarcity of potable water in the area. The water available in the well nearer to the mining lease is suitable for drinking. So far as surface water is concerned, there are no perennial rivers or other water bodies. Hence, there is no surface water pollution due to the proposed mining activities.
Mining activity will be above the general ground water level. The mining activity will have no adverse impact on the water region of the area. The water available in the well nearer to the mining lease is suitable for drinking. The small quantity of water will be accumulated in mine pits during rainy season. It will dry up during the course of time hence no dewatering will be required.
The minimum level of ground water in the area is 12 m bgl during monsoon and maximum level of water is 18m bgl during summer.
The maximum and minimum depth of working will vary between 6.5 and 3m depending upon the thickness of bauxite bed and topsoil. So, ground water table will not be intercepted by mine working and thus will not be affected.
It is expected that some water may be collected in mine pits during the rainy season, which will get percolated in the ground. Hence, no remedial measure is required as there is no effect.
At the conceptual stage, the waste land of the mine lease will be converted into water reservoir (for rain water harvesting, irrigation and recreation purposes) surrounded by green belt which will improve the aesthetics of the area.

4.3.2 Impact on Surface Water Quality
Due to poor rainfall, there are no perennial streams or rivers near the mine lease area. The mining rejects are in very small amount and do not contain any harmful ingredient. So, surface water resources in the area will not be impacted by mining activity. The quality of water in water reservoirs at conceptual stage will also be unaffected due to non-toxic waste.
The maximum depth of mine will be 6.5m bgl, while the ground water depth is 12m bgl during monsoon and 18m bgl during summer. So, groundwater will not be intercepted by mine working and thus will not be affected by mining activity.
Impact on Ground Water Quality
Ground water pollution can take place only if the mining rejects contain chemical substances. 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 sanitary waste will be routed to septic tanks followed by soak pits. The waste water from vehicular washing after separation of oil and grease will be used for dust suppression.
The sump also behaves as primary settling tanks for the mine water. Thereby, the suspended solids, the major contaminant added to the mine water inflow, would settle down and clean tapped water 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 that water is collected in these garland drains and discharged properly inside the mine pit. Working faces will be laid such that the water from the working areas will flow into the sump by gravity from where it will enter in mine pits. Face pumps of adequate capacity will be provided at working faces to keep these dry. Slurry pumps will be provided to deal with slurry formed during rainy season.
Surface Water Pollution Control Measures
The water channels/drains carrying the rain water from the mine will be provided with baffles and settling pits to arrest the suspended solids, if any, present in this water; The worked out slopes will be stabilized by planting appropriate shrub/grass species on the slopes. This will help in preventing wash-off of ore from these slopes; The mine water will be regularly tested for presence of any undesirable elements and appropriate measures will be taken in case any element is found exceeding the limits prescribed by CPCB and SPCB
Ground Water Pollution Control Measures
The domestic sewage from the toilets will be routed to septic tanks.
Regular monitoring of water levels and quality in the existing open wells and bore wells in the vicinity will be carried out. If found necessary, additional observation wells will be sunk for monitoring the water levels and quality around the mine representing both upstream and downstream conditions.

4.4 Impact on Land Use
The proposed opencast mine will result in disturbance of the land use pattern of the ML area. The land degradation is expected during mining activities like excavation, overburden dumping, soil extraction etc. Land requirement for the project has been assessed considering functional needs.
The potential adverse impact of opencast mining is the change in land use pattern. So reclamation of mined out land will be given due importance as a step for sound land resource management.
The lease area is of 67.1827 ha. Fertility of land is very poor. Within the proposed area the pre-mining break up of land is as follows:
Existing Land Use:
The area was under mining operation. Land acquired for mining activity and other infrastructures along with post mining reclamation of the area in the form of making water bodies, plantations, recreation areas etc are presented in Table-4.3

At the conceptual stage, about 46.1951 ha area will be disturbed due to mining activity. A part of excavated area will be converted to water reservoir. In addition to this about 17.3849 ha of undisturbed area will also be covered under afforestation and 0.9 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 to mining operation.
4.5 Impacts due to disposal of Overburden
No overburden is generated from the mining of bauxite. There is only generation of top soil and wastes in the form of associated clay which is below the threshold grade.
The generation of waste during the excavation of ore is given in Table-4.4.
Table-4.4 GENERATION OF WASTE
Year Top Soil (cum) Mineral Waste (cum) Reuse/spreading Storage 2015-16 Nil 7945 2016-17 2128 11985 2017 -18 21965 8969 2018-19 Nil 6583 2019-20 Nil 6454 Total 33039 41963
In the proposed mine scheme, waste generated during mine scheme period will be stacked in the mined out area simultaneously. Soil will be spread over statutory barrier and reused for plantation. The mined out land will be used as water reservoir.
4.5.1 Impact on Soil vis-à-vis Generation of Solid Waste
Mining operations involve removal of soil, creation of depressions due to voids caused by removal of mineral / overburden rocks ‘in-situ’, change in relief of the
IV-16 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures area and of landscape etc. The entire waste generated will be backfilled and there will be no external overburden dump left at the end of the mine life.
The dust generated during blasting operations, loading and unloading operations and vehicular movement normally constitute heavier particles that would readily settle on very small areas within the mining area itself. On account of various associated activities there would be increased vehicular traffic on these areas. These may generate additional particulate emissions. Generation of particulate emissions is therefore, of primary concern in the project. Adequate mitigation measures will be adopted for the suppression of dust which is already discussed in details.
There will be minimum impact on the soil due to the generation of solid waste as the soil will be stocked separately for further reclamation and rehabilitation. Further, the proposed greenbelt program with diversified species not only increases the biomass, soil fertility, productivity but also works as pollution sink and control of soil erosion. Hence, the likely impact on the soil characteristics will be insignificant.
4.6 Impact on Air Quality
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 by various activities in mining area is considered as an area source. Blasting is the main source of instantaneous point sources. Majority of the heavy machinery is operated on diesel. The mining activity is likely to contribute Suspended Particulate Matter (SPM), Dust from area sources and Oxides of Nitrogen (NOx) and hydrocarbons from automobile exhaust. The existing baseline concentrations of pollutants are within the limits prescribed by CPCB. The sources of pollutants from mining activities are given in Table-4.5.

TABLE-4.5 SOURCES OF POLLUTANTS
Sr. No. Source Type of Pollutant 1 Mining activity (drilling, blasting, loading) SPM, NOx 2 Transport of Overburden or soil for SPM dumping/ backfill and bauxite to sorting/sizing 3 Dumping of waste SPM 4 Sorting of bauxite and loading SPM 5 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 maximum during summer season (when the wind velocities are likely to be high) and almost nil during the monsoon season. The dust emissions are likely to be confined to the mine premises only.
4.7 Proposed Mitigation Measures for Dust Suppression
Bauxite is a hydrated oxide of aluminum. It is a mixture of two or more hydroxides corresponding to Gibbsite (Al2O3.3H2O) and Boehmite (Al2O3.H2O). The moisture content in Bauxite is around 3% to 7%. Therefore emissions due to mineral handling during mining operation 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, dozing, blasting, loading, haulage etc. Proper mitigation measures will be practiced during mining activities to control air pollution load below the prescribed limits.
In the proposed project, drilling will be done with latest drill machines with vacuum suction for dust extraction thus the likelihood of dust emission from drilling activities is negligible.
IV-18 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures
Blasting is the main source of instantaneous point sources. Blasting is usually carried out by deep holes. Blasting in the mining is conducted through deep blast holes of about 6 m to 7 m depth. SPM and NOx emissions are envisaged during the blasting and transportation operations. The large quantity of dust will be wind borne due to blasting but due to the proposed greenbelt around the mine, the spread of dust will be arrested. But these are kept under control by monitoring regularly the emissions from exhaust and using appropriate control measures by sprinkling of water on haul roads etc. The gaseous emissions like Oxides of Nitrogen from the blasting activity will be instantaneous and will prevail for shorter duration. The blasting will be carried out only between 2 pm to 3 pm during noon when normally low wind conditions prevail and temperature inversions are not likely to occur.
In addition to the above the production of blast fumes containing noxious gases will be 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 will be air pollution due to activities like transport of bauxite and overburden and generally due to the movement of vehicles on the roads. The proposed greenbelt and regular water sprinkling will help reduction in fugitive emissions.
IV-19 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures
Automatic water sprinklers will be installed in the mine. Pressurized water will be sprinkled. Dust generation is reduced by using sharp teeth for shovels.
With the proposed control measures, the fugitive emissions will be insignificant in terms 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 transfer points 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 the CPCB/SPCB in this regard.
4.8 Noise Environment- Impacts & Mitigation
4.8.1 Noise Impact on Working Environment
Mining operations will be the main sources of noise pollution. Noise due to
IV-20 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures vehicular movement 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 in the area:
Drilling; Blasting; Operation of HEMM; and Vehicular Movement.
It has been observed that mechanization of mine generally leads to higher noise levels if not properly controlled. Operation of drills, shovels, dumpers, pay loaders and dozers involve noise generation above 90 dB(A), which is the prescribed Threshold Limit Value. However, the expected noise levels are not likely to have any effect from the occupational health point of view.
With the mining operations, due to the deployment of machinery, drilling and blasting for mine development, excavation, and transportation of bauxite and men, it is imperative that noise levels would increase. However, as the mine lease boundary is located nearby about 500m to 1 km away from the nearest settlement, the expected noise levels will not have significant effect on the community.
Noise Generated due to Drilling
The drilling operations in mine will be carried out by using 100mm dia rotary percussive drills. The typical Noise levels due to drilling at 1-m distance will be about 85 – 90 dB (A). However, it is proposed to provide inbuilt cabin for drill operators with ear muffs/ear plugs. The mine site where heavy earth moving machinery will operate, noise level will be more than the stipulated 90 dB (A) norm of DGMS. The noise level will be within the tolerance limit at a distance of 15 to 20 m. The protection measures for the operators of the equipment will reduce the impact.
IV-21 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures
The noise produced by blasting will be for extremely short duration of around 0.5 seconds, though with a high intensity. The impacts over the surrounding habitat can be minimized by adopting adequate precautions during blasting and also by properly scheduling it as indicated in the management plan. Development of greenbelt along the periphery of the mine site is expected to act as an effective barrier against its propagation 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 seconds to 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. Controlled blasting and delay blasting will be used to reduce to noise due to blasting.
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 with distance. Blasting will be carried out maximum two times per week between 12.00 Noon to 2.00 PM. As the blasting is likely to last for very short duration depending on the charge, the noise levels over this time will be instantaneous and short in duration.
The noise levels in many situations will be above Threshold Limit Value. Exposure to noise levels, above Threshold Limit Value may have detrimental effect on the workers' health. Mine workers working for more than 4 to 4.5 hours per shift will be greatly affected, unless suitable mitigatory measures are taken. The adverse effects of 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 the form of waves impinges the eardrum, it begins to vibrate, stimulating other delicate tissues 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 cases to loss of hearing. Detrimental effects of noise pollution are not only related to sound pressure level and frequency, but also on the total duration of exposure and the age of the person.
Frequency levels and associated mental and physical response of humans are given in Table-4.6.
TABLE-4.6 NOISE EXPOSURE LEVELS & ITS EFFECTS
Noise Levels Exposure Time Effects dB(A) 85 Continuous Safe 85-90 Continuous Annoyance and irritation 90-100 Short term Temporary shift in hearing threshold, generally with complete recovery Above 100 Continuous Permanent loss of hearing Short term Permanent hearing loss can be avoided 100-110 Several years Permanent deafness 110-120 Few months Permanent deafness 120 Short term Extreme discomfort 140 Short term Discomfort with actual pain 150 and above Single exposure Mechanical damage to the ear Source: Hand Book of EIA, Rao & Wooten
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 transportation

TABLE-4.7 TYPICAL NOISE GENERATION DUE TO EXCAVATION/LOADING/TRANSPORTATION EQUIPMENT
Sr. Name of the Equipment Nos. Noise at Source dB(A) No. 1 Tippers 6 75 - 90 2 Excavators 2 75–90 4 Jack Hammer (RH 658/42) 1 5 Compressor 1
The total noise from all of the above equipments occurs only when all the equipments operate together and simultaneously, which is a remote possibility.
It is proposed to provide air conditioned cabins in Excavators and Tippers to reduce noise impact to the operators.
All equipments will be maintained in good condition to reduce the noise levels. The trucks and tippers will also be regularly serviced and maintained in good condition to reduce noise. The truck drivers will be instructed not to use power horns near residential areas.
Noise Dispersion from the Mine
The noise generation from the mine will be from various sources, which will be originating from various locations within the Mines. For the purpose of noise dispersion, it is assumed that all the noise generating sources from the mine as one source. The dispersion of this noise is computed by using the below mentioned model.
Input to the Mathematical Model for Sound Wave Propagation during Operation
Major noise sources as cumulative noise source has been identified. For convenience of the contours, 100 m grid scale is chosen for the immediate impact of the nearby villages from the mine. The center of the central part is taken as
IV-24 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures center (0,0) for calculating the co-ordinates of noise generating sources within the mining area. An attempt has been made to predict the noise levels at the boundary of the mining site. Coordinates X and Y are taken as input to the model is correlated with grid size and scale (1:100 m). Thus, the center of the mining area is defined as 0,0 coordinates.
The input to the model has been taken as the cumulative noise generating sources.
Noise Impact Analysis on Community
The noise levels in the working environment are compared with the standards prescribed by Occupational Safety and Health Administration (OSHA) which in- turn are being enforced by Government of India through Model rules framed under the Factories Act. These standards were established with the emphasis on reducing the hearing loss. It should be noted that each shift being of 8-hr duration, equivalent noise level exposure during the shift is 90 dB(A).
4.8.4 Mitigation Measures
The noise level control measures at various stages of the mining will be as given below:
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 combination with sequential blasting machine; No trunk line of detonating fuse will be used on surface (Even if detonating fuse is 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;
IV-25 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures
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 & mitigation measures
Ground vibration, fly rock, air blast, noise, dust and fumes are the deleterious effects of blasting on environment. The explosive energy sets up a seismic wave in the ground, which can cause significant damage to structures and disturbance to human occupants. It causes major damages to the pit configuration too.
When an explosive charge is fired inside the blast hole, it is instantly converted into hot gases, which exert intense pressure on the blast hole walls. High intensity shock waves propagate radially in all directions and cause the rock particles to oscillate. This oscillation is felt as ground vibration. The proposed mining operations using deep hole drilling and blasting using delay detonators are bound to produce ground vibrations.
Blasting, in addition to easing the hard strata, generates ground vibrations and instantaneous noise. Ground vibration from mine blasting is expressed by amplitude, frequency and duration of blast. The variables, which influence ground
IV-26 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures vibrations are controllable and non-controllable. The non-controllable variables include general surface terrain, type and depth of overburden and wind. Similarly, the controllable variables include type of explosives, charge per delay, delay interval, direction of blast progression, burden, spacing and specific charge and coupling ratio.
The oscillation of rock particles is called Particle Velocity and its maximum value is called Peak Particle Velocity (PPV), which is measured in millimeter per second. The standards for safe limit of PPV are established by Director General of Mines Safety for safe level criteria through Circular No. 7 dated 29/8/1997. The safe level criteria PPV as mentioned in Circular No. 7 of DGMS is presented in Table-4.8.
TABLE-4.8 PERMISSIBLE PEAK PARTICLE VELOCITY (mm/s)
Type of Structure Dominant Excitation Frequency <8 Hz 8 – 25 >25 Hz Hz A] Buildings/structures not belonging to the owner Domestic houses/structures (Kuchha brick 5 10 15 and cement) Industrial Buildings (RCC and framed 10 20 25 structures Objects of historical importance and sensitive 2 5 10 structures A] Buildings belonging to the owner with limited life span Domestic houses/structures (Kuchha brick 10 15 25 and cement) Industrial buildings (RCC & framed 15 25 50 structures) Source: DGMS Circular No. 7 dated 29/08/1997
As the distance increases, the PPV value is likely to reduce. The ground vibrations generated by blasting during the mining operations will be well within the standards prescribed by DGMS by controlled blasting. Ground vibrations are not likely to affect the structures in the vicinity of mine lease area. By adopting controlled blasting, the problems will be greatly minimized at mines. The impacts are also minimized by choosing proper detonating system, optimizing IV-27 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures total charge and charge/delay. Noiseless trunk delays to minimize the noise due to air blast, non-electric (NONEL) system of blasting for true bottom hole initiation, muffling mats to arrest the dust and fly rock will be adopted. Hence, the impact due to ground vibration will be significantly reduced.
4.9.1 Vibration Abatement
The blasting operations are proposed to use deep hole drilling and blasting using delay detonators which are bound to reduce the ground vibrations. Further, the ground vibrations will be controlled by using modern shock tubes with delay non- electric (nonel) detonators. The following mitigation measures should continue to be practiced.
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 whether 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;
IV-28 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures
S/B >1 S = hole spacing, B = distance between rows (burden); Effective stemming of the explosives will be done in the drill holes; 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.
In order to reduce ground vibrations caused by blasting the following additional precautions will be taken: a) To provide proper free face to each hole to keep maximum charge per delay within limit, holes will be blasted with a combination of short delay detonators and sequential blasting machine; b) To minimize vibration level, burden of first row as well as effective burden for other holes will be kept optimum; c) Holes will be drilled at 10 degree inclination from vertical so more explosive energy is utilized in productive way as in vertical hole only 50% of energy is utilized in productive way; d) Holes will be charged with proper quantity of explosives instead of excessive charging. e) Keep coupling ratio (ratio of charge diameter to hole diameter) minimum for high strength booster explosives; f) Larger column of hole will be charged with low-density explosives i.e., ANFO etc instead 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; and i) 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 it from rain and wind erosion. The plantation scheme broadly covers the following areas:
Greenbelt around peripheral portions of the ML; and Afforestation on top soil dumps and either sides of the haul roads. Afforestation on undisturbed mine lease area.
Full-fledged horticulture department under the guidance of the experienced horticulturist will carry out the Greenbelt development programme.
Plantation will be raised in the 7.5 m wide green belt in the safety zone around the mining lease by planting the native species around ML area, around water body, roads etc. 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 belt in ML area. About 0.4587 ha of land will be brought under green belt development in first five years of operation. Area available for afforestation and green belt in mine lease at the end of mine life is 17.3849 ha. 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 plantation species is considered 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;
IV-30 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures
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 in study area. There are no wildlife sanctuaries/ wildlife corridors in 10-km area around the mine lease boundary. Because of air pollution control measures, surrounding agricultural crops will not be affected.
No loss of forest resource is envisaged due to the project. The impacts on flora are briefly described in the following sections:
4.11.1 Impact on Terrestrial Ecology & mitigation measures.
Flora
There is forest area at a long distance in the given buffer zone of 10 km. The mining activity may have some impact on the flora due to the proposed mining of bauxite.
The impact on terrestrial ecology will be due to emission of gaseous pollutant like NOx. The pollutant at a very low dose acts as an atmospheric fertilizer for the vegetation. However, at higher doses, they are injurious to both vegetation as well as animals. The air pollution control measures will reduce the pollution levels to non-injurious levels.
Extensive plantation comprising of pollutant resistant trees is undertaken, which will serve not only as pollution sink but also as a noise barrier. It is expected that with the adoption of these mitigatory measures, the impact due to operation of the mine will be minimal on the terrestrial ecosystem.
Fauna
The adverse impacts on fauna would be mainly due to:
IV-31 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha( mine working area 59.0889 ha) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-4 Anticipated Environmental Impacts and Mitigation Measures
Human activity; Noise; and Land Degradation.
The impact on the fauna of the buffer zone due to the mining activity will be marginal as minimum disturbance will be there outside the mine lease area. The proposed progressive mine closure, plantation and pollution prevention and control over a period of time will create conditions favourable for fauna.
4.11.2 Impact on Aquatic Ecology & mitigation measures
There is no perennial river or nalla near the mine lease area. No wastewater generation is envisaged from the mining operations. The domestic sewage is sent to septic tank followed by soak pit. The rainwater and seepage water collected 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. Mining will not intersect ground water and hence, groundwater will not be affected.
4.11.3 Mitigation Measures
No impact is envisaged on biological environment of the area. However, extensive greenbelt / green cover will be developed in and around ML area.

5.0 ANALYSIS OF ALTERNATIVE TECHNOLOGY AND SITE 5.1 Site Alternatives under Consideration
Presence of bauxite for commercial exploitation has been identified based on the result of geological investigations and exploration carried out by the Geological Survey of India (GSI). The mining projects are site specific as such alternate sites were 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 deposit characteristics, percentage recovery, requirement of health and safety and environmental concerns, production, scheduling scope of mechanization and automation, workforce requirements wage rates, land reclamation, operating and capital cost estimates. The selection of the mining method (development and extraction) 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 mineral deposits. Mineral is drilled, blasted, loaded into trucks, and hauled to a facility where it is crushed and ground to a uniform size for further processing. Surface mining requires the removal and disposal of layers of top soil and underlying rock commonly called the overburden. Mining must be planned so that the combine of mining processing and reclaiming the land is taken up concurrently. The opencast mining method will be adopted because of the following reasons: The opencast mining operations ensure higher mineral conservation.
The method used for mining is efficient for bauxite mining, so no alternative mining method is proposed.

6.0 ENVIRONMENTAL MONITORING PROGRAMME
6.1 Introduction
The industrial development of any area needs to be intertwined with judicious utilization of non-renewable resources of the study area and within the limits of permissible assimilative capacity. The assimilative capacity of the study area is the maximum amount of pollution load that can be discharged into the environment without affecting the designated use and is governed by dilution, dispersion and removal due to physico-chemical and biological processes. The Environment Monitoring Programme is required to ensure sustainable development in the study area (10 km) of the project site, hence it needs to be an all encompassing plan for which the plant authorities, Government, Regulating agencies like Pollution Control Board etc. working in the region and more importantly the affected population of the study area need to extend their co- operation and contribution.
6.2 Implementation Schedule of Mitigation Measures The mitigation measures suggested in Chapter-4 will be implemented so as to reduce the impact on the environment due to the operations of the proposed project. Implementation schedule of mitigation measures is given in Table-6.1.

6.2.1 Administrative Aspects & Environmental Monitoring Program
Regular monitoring of environmental parameters is of immense importance to assess the status of environment during project operation. With the knowledge of baseline conditions, the monitoring programme will serve as an indicator for any deterioration in environmental conditions due to operation of the project, to enable taking up suitable mitigatory steps in time to safeguard the environment. Monitoring is as important as that of control of pollution since the efficiency of control measures can only be determined by monitoring.
Usually, as in the case of the study, an Impact Assessment study is carried over short period of time and the data cannot bring out all variations induced by the natural or human activities. Therefore, regular monitoring programme of the environmental parameters is essential to take into account the changes in the environmental quality.
6.2.2 Institutional Arrangements for Environment Protection and Conservation
The mine will be supervised and controlled by Mines Manager supported by adequate team of technically and statutorily qualified personnel apart from the operating staff of skilled, semi-skilled, unskilled and other categories.
The organizational structure for Environment Cell for mining operations is shown in Figure-6.1. This Environment Cell is responsible for the management and implementation of the environmental control measures. Basically, this department will supervise the reclamation planning & management, air & water pollution control management, Liasoning with State & Central Statutory agency & Committee.
In case the monitored results of environmental pollution are found to exceed the allowable limits, the Environment Management Cell will suggest remedial action and get these suggestions implemented through the concerned authorities.

6.3 Environment Monitoring Programme
Monitoring shall confirm that commitments are being met. This may take the form of direct measurement and recording of quantitative information, such as emissions and wastes, for measurement against corporate or statutory standards, consent limits or targets. It may also require measurement of ambient environmental quality in the vicinity of a site using ecological/biological, physical and chemical indicators. Monitoring may include socio-economic interaction, through local liaison activities or even assessment of complaints.
The environmental monitoring will be conducted in the mine operations as follows: Air quality; Water quality; Noise levels; Soil Quality; and Greenbelt Development The details of post project monitoring is presented in Table 6.2
6.4 Reporting Schedules
Post project monitoring will be carried out as per conditions stipulated in environmental clearance letter issued by MOEF, consent issued by SPCB as well as according to CPCB guidelines. The project site is considered as core zone and the area lying within 10 km radius from the mine site is considered as buffer zone, where some impacts may be observed on physical and biological environment. In the buffer zone, slight impact may be observed and that too is occasional, table below showing the details of post Project Monitoring programme.

7.2 Occupational Health & Safety and Disaster Management Plan
7.2.1 Occupational Health & Safety: 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 follows:- Physical Hazards due to Mining Operations: Following health and safety related physical hazards were indentified 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 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 air temperatures may exceed 480C in the mining area.

3. Eye Irritation: - During the high windy days in summer the sandstorms could be the problem for itchy and watery 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. Some workplace hazards have the potential to cause injury or disease that specific regulations or codes of practice are warranted. These regulations and codes, adopted under state and territory OH & S Acts explain the duties of particular groups of people in controlling the risks associated with specific hazards. Codes of Practice provide advice on how to meet regulatory requirements. As such, codes are not legally enforceable, but they can be used in courts as evidence that legal requirements have or have not been met. 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 employee, 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. 7.2.

Figure 7.2. Policy & Methods of the Management
7.2.2 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; 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 VII-47 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha(mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-7 Additional Studies
may enter into the systemic circulation and thereby reach essentially all the organs of body and affects different tissues. Continuous working and improper working position leading to pain & exhaustion.
The OHS system: The entire OHS system will be designed as per Fig. 7.3.
Fig. 7.3: OHS system
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 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.

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.
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. 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.
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:
VII-50 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha(mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-7 Additional Studies
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.
Protection from fall: In mining projects, workers are exposed to working at uneven sites with pits and slopes not properly designed. 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. 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 scheduled 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.

7.3 Disaster Management Plan
7.3.1 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.
7.3.2 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. 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 VII-53 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha(mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-7 Additional Studies
can affect loss of life, production and property.
7.3.3 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 -Toxic gas release -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
7.3.4 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 that has already happened in other mining projects. iii. An action plan to handle disaster.
7.3.5 Identification of Hazardous Process/Area:
The entire area is prone to hazard.
7.3.6 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-54 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha(mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-7 Additional Studies
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.
7.3.7 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
VII-55 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha(mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-7 Additional Studies
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. 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:
VII-56 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha(mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-7 Additional Studies
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: 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.
7.3.8 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 VII-57 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha(mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-7 Additional Studies 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 system will be explained to one and all to avoid panic or misunderstanding during disaster.
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.
Fire Fighting The proposed project will be provided with fire protection systems as given in Table 7.4.

7.4 SOCIAL IMPACT ASSESSMENT, REHABILITATION & RESETTLEMENT (R&R) ACTION PLAN
Introduction In 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-Mewasa, Sub-district Kalyanpur, District Jamnagar, 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 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 Study
The 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
VII-68 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha(mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-7 Additional Studies 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. 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
VII-69 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha(mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-7 Additional Studies
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. 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.

Chapter-9 Environmental Management Plan
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. • Proper use of natural resources and water. • Safety, welfare and good health of the work force and populace. • Ensure effective operation of all control measures. • Monitoring of cumulative and long-time impacts. 9.1 Air Quality Management Bauxite is a hydrated oxide of aluminum. It is a mixture of two or morehydroxides corresponding to Gibbsite (Al2O3.3H2O) and Bohemite (Al2O3.H2O). The moisture content in Bauxite is around 7%.Therefore, dust emissions due to mineral handling, during mining operations arenot much and restricted to the lease area only. Air pollution is causedmainly due to dust generation added with gaseous emission fromtransportation 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 Equipment (PPE) like dust masks, ear plugs etc.by the mine workers. • Controlled blasting will help inreducing the above emissions. • Regular water sprinkling on haul roads & loading points will be carried out. • Development of green belt/plantation around the lease boundary, roads, dumpsetc.

Chapter-9 Environmental Management Plan
• Ambient Air Quality Monitoring will be conducted on regularly basis to assessthe 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 will help in reducing the above emissions. • Proper maintenance of machines improves combustion process & makesreduction in the pollution. Good maintenance and monitoring of fuel and oilwill not allow significant addition in the gaseous emission. 9.2 Noise Pollution Control 9.2.1 Noise Abatement and Control • Proper maintenance, oiling and greasing of machines at regular intervals willbe 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 andmine area will be done to minimize the propagation of noise. • Personal Protective Equipments (PPE) like earmuffs/earplugs will beprovided to all operators and employees working near mining machineries orat higher noise zone. • Periodical noise level monitoring will be done. 9.2.2 Protective measures for fly rocks caused by blasting • Overcharging will be avoided. • Supervision of drilling and blasting operations to ensure design blastgeometry; • Blasting operations will be carried out only during day time as per minesafety 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.

Chapter-9 Environmental Management Plan
9.3 Water Conservation Measures Water for drinking and operations is required to be 15 KLD. It is proposed to obtain water for drinking from nearby villages. Adequate control measures will be adopted to check not only the wash-off from soil erosion but also uncontrolled flow of mine water. The mine working (6.5 m bgl) will not intercept ground water table (12-18 m bgl) and will not affect ground water quality. Mine pits will be used to store run-off water in water reservoirs which will be useful in rainwater harvesting. Due to scanty rainfall there are no perennial rivers or streams near the lease area thus surface water bodies will not be affected by mining activity. The stored run-off water in the mined out pits will be used for watering of the afforested areas and also dust suppression. Bauxite mining does not cause any contamination in surface as well as ground water and also, there is no intersection of groundwater due to mining activities. 9.4 Waste Management 9.4.1 Nature of waste: The quantum of wastes removed is given below:

10.7 BASELINE ENVIRONMENTAL STATUS
10.7.1Soil Quality
Five soil samples were collected in and around the mine lease area to assess the present soil quality of the region. The pH of the soil indicates that the soil is slightly acidic in nature. Based on the results, it is evident that the soils are not contaminated by any polluting sources.
10.7.2 Meteorology
Meteorological data at the site was monitored during March 2015 to May 2015 representing pre-monsoon season. It was observed that the during study period, temperature ranged from 19.1 0C to 42.2 0C. During the same period of observations, the relative humidity recorded was ranged from 11.7% to 79.35%.
10.7.3 Ambient Air Quality
Ambient Air Quality Monitoring (AAQM) has been carried out at fourteen locations pre-monsoon season of March 15 to May 15. The Particulate Matter (PM10) conc. ranged between 50.1 µg/m3 to 99.7 µg/m3 with the 98th percentile ranging between 63.3 µg/m3 to 98.2 µg/m3, Sulphur dioxide (SO2) between BDL to 6.8µg/m3 with the 98th percentile ranging between 5.8 µg/m3 to 6.8µg/m3, Oxides of Nitrogen (NO2) between 6.5µg/m3 to 18.6 µg/m3 with the 98th percentile ranging between 12.5µg/m3 to 18µg/m3. The results thus obtained indicate that the concentrations of PM10, SO2 and NO2 in the ambient air are well within the National Ambient Air Quality (NAAQ) standards for Residential and Rural areas.
10.7.4 Water Quality
X-9 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha(mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-10 Summary & Conclusion
To assess the physical and chemical properties of water in the region, water samples from five locations were collected from various water sources around the mine lease area. The pH of the ground water samples in the region varied from 7.60 to 8.21. Concentration of Fluorides varied from 0.7 mg/l to 2.1 mg/l.
The higher chloride level was found in the ground water samples from villages Mewasa & Kenedy & for surface water it is 42 mg/l to 152 mg/l the chloride samples crossed the desirable limit. The chloride level of 18125 mg/l is observed in Pindara Bay sample due to mixing of sea water.
The results indicate that due the presence of saline water in the vicinity of the mine lease area, both groundwater and surface water are not in conformity with the drinking water standards (IS: 10500) and IS-2296 respectively.
10.7.5 Noise Levels
Ambient noise levels were measured at seven locations around the proposed mine site. The daytime and nighttime noise levels ranged between 50.4 to 68.4 dB (A) and 40.6 to 54.6 dB (A) respectively. The daytime and nighttime noise levels in all the locations were observed to be within the permissible limits. 10.7.6 Ecological Environment
Based on the field studies and review of published literature, it is observed that there is a Schedule-I species in the buffer zone. There is presence of Marine National Park, Marine Sanctuary-Eco sensitive Zone in the buffer zone of the lease area.
10.7.7 Social Environment
No impact is envisaged on the population composition of the study area as there will be no in-migration or out-migration of villagers. Those who will be engaged for extraction of bauxite and laterite from the mining site will be recruited locally. It is expected that on an average 48 workers will be engaged by the project proponent for the extraction of bauxite. Most of the workers will be engaged for the operation

10.8 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES
10.8.1 Impact on Air Quality & Mitigation Measures
Bauxite mining is carried out by opencast fully mechanized method. The air borne particulate matter generated by ore and handling operations, and transportation of ore is the main air pollutant. The emissions of Sulphur dioxide (SO2), Oxides of Nitrogen (NOx) contributed by diesel operated excavation/loading equipment and vehicles plying on haul roads are marginal. Prediction of impacts on air environment has been carried out taking into consideration proposed production and net increase in emissions, in Final EIA Report. Air pollution sources in the operating mine have been classified into: Line sources A. Drilling & Blasting, stockpiling, extraction and loading of ore by various activities in mining area are considered as area sources B. Transportation of ore from mining benches to tipper platform of plant, movement of tippers on the haul road is considered as line sources. Water tankers with spraying arrangement will be used for regular water sprinkling on the haul roads to ensure effective dust suppression. The tippers are well maintained so that exhaust smoke does not contribute abnormal values of noxious gases and un-burnt hydrocarbons.
10.8.2 Impact on Water Resources & Mitigation Measures
X-11 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha(mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-10 Summary & Conclusion
Surface Water Resources As there is no seasonal nalla or water body within or nearby the leasehold area. The surface water resources will not be affected by mining activities.
Groundwater Resources Ground water level of the area in general is about 12m below the ground level. The mining activity will be restricted up to a maximum depth of 6.5m from ground level. Therefore, the mining activity in the leasehold area will not make any impact on ground water. Moreover, the reclamation of mine pits in water reservoirs will be helpful in rainwater harvesting and recharge of ground water.
10.8.3 Impact on Water Quality & Mitigation Measures
Analysis results of surface water samples collected from rivers and nallas in the buffer zone indicate that the pH is well below the prescribed limits whereas the total dissolved solids (TDS), chloride content and hardness exceed the permissible limits which may be due to sea water ingress in the study area which is near to the coast. No wastewater generation is envisaged due to the mining operations. The sanitary wastewater will be sent to septic tank. No impact of wastewater generation on the surface water is envisaged, as there is no discharge into surface water resources.
10.8.4 Impact on Noise Levels and Ground Vibrations & Mitigation Measures
With the mining operations, involving deployment of machinery, drilling and blasting for mine development, excavation and transportation of bauxite, it is imperative that noise levels would increase. It is also observed that these incremental noise levels will not significantly affect the existing ambient noise levels, with the adoption of controlled blasting techniques, regular maintenance of HEMM, tippers and trucks, as well as restricted use of power horns by truck in residential areas.
10.8.5 Impact on Soil & Mitigation Measures
X-12 EIA for the Proposed Virpur, Mewasa, Kenedy & Mota Asota Bauxite Mine (67.1827 ha(mine working area 59.0889 ha)) for a Peak Production of 5,99,300 TPA at Kalyanpur Taluka, Devbhumi dwarka District, Gujarat Chapter-10 Summary & Conclusion
The environmental impacts of the mining activities on topsoil are based on the quantity of removal of topsoil and its dumping. In the present project as it is proposed to temporarily store the topsoil and use it for plantation schemes, no adverse impact of excavation of topsoil is envisaged. The soil erosion from overburden dumps is not envisaged in the present project, as sufficient measures as detailed in the EMP would be undertaken.
10.8.6 Impact on Flora and Fauna & Mitigation Measures As the mining activity is restricted to core zone, no significant impact on the flora of the buffer zone due to the proposed mining of bauxite is anticipated. Extensive plantation comprising of pollutant resistant trees will be undertaken, which will serve not only as pollution sink but also as a noise barrier. The incremental dust generations due to the mining operations, at the boundary of the mine lease are insignificant and it is also expected that with the adoption of mitigatory measures as suggested in EMP, the impact due to operation of the mine will be minimal on the terrestrial ecosystem and also on the adjacent forest area. The impact on the fauna of the buffer zone due to the mining activity will be insignificant. The dust suppression methods and proposed progressive plantation over a period of time will reduce the impact, if any, on the fauna.
10.8.7 Impact on Land Use Pattern & Mitigation Measures The proposed opencast mine will result in change the land use pattern of the ML area. The land degradation is expected during mining activities like excavation, overburden dumping, soil extraction etc. however, the present barren land of mine lease will be converted at conceptual stage, in multiple useful water reservoirs and green belt and plantations, improving the aesthetics of the area.
10.8.8 Impact on Socio - Economic Aspects & Mitigation Measures
The mine area does not cover any habitation. Hence the mining activity does not involve any displacement of human settlement. No public buildings, places, monuments etc exist within the lease area or in the vicinity. The mining operation

Thus no adverse impact is anticipated. The impact of mining activity in the area is positive on the socio-economic environment of the region. Virpur, Mewasa, Kenedy and Mota Asota Bauxite Mine will be providing employment to local population and it will be give preference to the local people whenever there is requirement of man power. The CSR activity will provide better infrastructure facilities to the local people.
