CHAPTER - I
1.1 Purpose of the Report:
The growth of mining / industry significantly contributes towards economic progress of the country. However, any project progress brings along with it a number of environmental problems. Many of these problems can be avoided, if adequate environmental control considerations are thought of during conceptual stage of the project. Once the project is set up, it becomes very costly to install pollution control equipment and implement other environmental control measures, if the same are not considered in the conceptual stage. Any project exerts both positive and negative environmental impacts. Negative impact cause environmental degradation. It is the responsibility of Planners, Scientists and Environmentalists to document these impacts separately so that these can be identified, quantified and attempts may be made to minimize negative impacts and maximize the positive impacts for better development with least environmental degradation.

1.7 Pre-appraisal of EIA Projects
The MoEF & CC, vide its EIA Notification 2006, has made Eenvironmental Clearance mandatory for new project or expansion or modernization of any activity if pollution load exceeds existing levels and also for new project listed in schedule. MoEF & CC Has developed guidelines for the preparation of EIA reports. Among these guidelines, pre-appraisal of the proposed project helps to judge whether the proposed project broadly fulfils the statutory requirements for setting up the industry / developmental activity. The critical issues in all these guidelines, which are given below are very important for initial appraisal of the project before taking up the EIA activity. With this view, the initial environmental examination has been undertaken for preliminary appraisal of proposed project to look at whether the proposed project satisfies the critical issues on board level so that EIA study can be undertaken for the purpose of application for environmental clearance.
The critical issues focused in all these guidelines are:
♦ Will the project location conflict with the nearby land use or preclude later developmental areas?
♦ Can the project operate safety without serious risk of accidents or long-term health hazards?
♦ How will the project affect economic activities that are based on natural resources?
♦ Is there sufficient infrastructure to support the project?
♦ How much of these resources (water, energy etc) will the project consume and weather supplies of these resources are available?
♦ What kind of human resources will be required of replace and what will be its social importance on short / long run?

1.11 Methodology for EIA
The impacts of existing and proposed activities in a region on environmental components can be assessed through Environmental Impact Assessment studies within the impact zone of the region. The results of EIA Studies form a basis for preparing a variable Environmental Management Plan (EMP) for mitigating the adverse impacts and to comply with the guidelines and regulations of regional and national regulatory bodies.
The present Environmental Impact Assessment study deals with the detailed study and data collection for various environmental components viz. air, noise, water, land, biological and socio-economic environment for Pre Monsoon season 2015 (Mar - May’ 2015).
For the environmental impact assessment studies, an area covering 10 km radial distance from the mining lease was selected as study area.
Air Environment
The topographical information of study area was collected. Different air pollution parameters like Sulphur Dioxide (SO2), Nitrogen Dioxide (NOx), Ammonia (NH3), Carbon monoxide (CO).
Particulate Matter of 10µm (PM10), Particulate Matter of 2.5µm (PM2.5), Benzene (C6H6), and other parameters were identified as related to the project activities for representing baseline status of ambient air quality within the study area. A temporary field centre cum laboratory was established in study area purpose of calibration of equipment, planning of fieldwork and chemical analysis etc. Data on micro-meteorological parameters viz., wind speed, wind direction and ambient temperature were collected by establishing Micrometeorological Station during the study period. A Steady State Gaussian Dispersion Model for multiple area and line sources has been used for prediction of impacts on ambient air quality.
Noise Environment
Noise, often defined as unwanted sound, interferes with speech, communication, causes annoyance, distracts a person from work, and disturbs sleep, thus deteriorating quality of

human environment. Noise pollution survey was, therefore, carried out in and around the proposed site and other places to assess the impact of the activity and human activities on the acoustic environment. The ambient noise level is characterized by significant variations above a base or residual noise level. The noise level below which the ambient noise does not seem to drop during a given time interval and is generally caused by unidentified distant sources is called as residual noise level. The annoyance that people experience depends upon the number of noise events that occur during a time interval. Noise levels were measured at several locations at proposed site, along the transportation routes, and at several locations in the human settlements around the Iron ore mining at different times of the day with precision noise level meter.
Water Environment
Information on surface and ground water resources in the study area was collected. The parameters of prime importance for water quality assessment were selected under physical, chemical, inorganic, organic, nutrients, heavy metals (abiotic parameters), plankton and bacteriological parameters (biotic parameters). For establishing baseline water quality status in the region, samples were collected at different locations including surface and ground water. Information on quantum of surface water resources available in the region and ground water potential of the region was collected from secondary sources.
Land Environment
Soil samples were collected from the proposed site, forest, agricultural fields, and other places in study area. Physico-chemical properties of the soils were determined to define the soil quality. Information on land use pattern in the study area was also collected from secondary data from Census of 2011. Land use pattern was also studied employing remote sensing techniques. Information regarding existing cropping pattern, crop types and yield of the crop was also collected from various sources.

Biological Environment
The parameters of prime importance to both biotic and abiotic factors have been selected to estimate the structural and functional changes in the ecosystem. Biodiversity with special reference to flora and wild life was also studied in the core and buffer zone. Water samples were also collected from rivers, lakes and groundwater sources for estimation of biological parameters viz., zooplankton and phytoplankton through detailed microscopic examination. Diversity Indices based on the biodiversity of plankton and forest flora were also computed to evaluate the biological quality status.
Socio-economic Environment
A field survey was conducted within the study area in randomly selected villages. The parameters selected under socio-economic component were demographic structure of the study area, provision of basic amenities, welfare facilities provided by the mine owners, safety training and management, community and occupational health hazards etc. Relevant information was collected from selected villages and analyzed. Data was also collected on quality of life indicators for establishing QoL status. All the aforesaid environmental parameters have been used for identification, prediction and evaluation of significant impacts. Modelling of environmental quality at appropriate places has also been undertaken to predict the impacts due the existing and proposed activities in the region.

CHAPTER – II
PROJECT PROFILE
2.1 Introduction
Bhilai Steel Plant of M/s Steel Authority of India Ltd. (SAIL), a Government of India enterprises, it is one of the five integrated steel plants under SAIL and is located strategically in the mineral rich central region of India. BSP has always been a major contributor to the bottom line of Maharatna Company- SAIL and hence is admired as its flagship unit. BSPs inbound supply chain has strategic advantage of having captive mines. The outbound supply chain logistics is facilitated by being located on the Howrah-Mumbai railway route. The entire value chain of BSP is supported by other corporate units of SAIL like Central Marketing Organization (CMO) - the largest industrial marketing network in the country, Research and Development Centre for Iron and Steel (RDCIS), Centre for Engineering and Technology (CET), Management Training Institute (MTI), Raw Materials Division, Environment Management Division, Growth Division and Safety Organization. BSP produces a wide range of Plates, world’s cleanest Rails, heavy structural’s, merchant Products (TMT Bars, Angles, Channels, and Rounds) and Wire rods (TMT, Plain, and Ribbed). BSP has been continuously improving its existing products and developing new products which have resulted in manufacture of value added and differentiated products. BSP products have found applications in a number of prestigious infrastructure projects and defence projects of the country in the areas of rail lines, bridges, dams, air / sea ports, refineries, pipelines, etc.
Bhilai Steel Plant (BSP) is undergoing expansion to increase hot metal production to 7.6 MTPA. Under expansion, BSP is setting up a large Blast Furnace (BF-8) of useful volume 4060 m3. Post expansion, the iron ore requirement for BSP will be about 12 MTPA from 9.5 MTPA at present. After expansion 80% Sinter and 20% Lump Ore & Pellet have been envisaged in BF burden. Dalli-Rajhara Iron ore complex is the existing captive iron ore mines of Bhilai Steel Plant (BSP) & Pandridalli Rajhara Pahar lease is one of the prime sources to supply Iron ore to BSP. The mines was in operation from the year 1958

To fulfill the consumption requirement of Iron ore of Bhilai Steel Plant it is proposed to enhance the Excavation of ROM capacity up to 3.50 MTPA. The existing method of mining, i.e. open cast mechanized will be continued in future. Removal of waste rock will be done simultaneously in a systematic manner to get the adequate exposure of iron ore faces. 50/60 tonner rear dump BEML / HM dumpers are engaged for transporting ore to Crushing & Screening Plant bunker situated in the adjacent lease tor processing with the ROM of other mines. & waste to designated waste dump after dumper is loaded by either 4.6 cum capacity electric rope shovel / 5.5 cum capacity hydraulic shovel. Presently no change is proposed in method of mining, however a possibility of enhancing equipment size particularly shovel and dumpers for enhancing capacity of mines in present setup is explored. In near future it is expected that higher capacity dumper up to 60/80 T or above pay load capacity may be introduced with matching volumetric capacity of shovel for achieving the proposed rate of excavation at Rajhara mechanised mine & if required one mobile crushing & screening facility of 1 MTPA capacity proposed be establish in future within the lease area. Also there is possibility of outsourcing of part excavation of ore and waste in order to meet the immediate ore requirements for production of hot metal in post modex scenario and delayed Rowghat project
2.2 Physiography of the area²
Rajhara Iron-Ore deposit occurring in Pandaridalli-Rajhara hills leasehold constitutes the eastern edge of Dalli-Rajhara Iron-ore belt stretching for about 15 km in a roughly E-W direction. The associated country rocks mainly consist of Phyllites, Quartz, Mica Schist’s and BHQ (Banded Hematite Quartzite). The BIF (Banded Iron formations, viz. the BHQ and Iron-ore bodies) occur as resistant outcrops for a considerable stretch forming

General elevation of the ground is around 425 mRL on the northern stretch of the hills. It is, however, still lower on the southern/se side of the hills falling down to about 370 mRL. The Iron-ore deposit in the leasehold comprises two distinct blocks, viz. Rajhara-main block and Kokan-West block, associated with Phyllites and Mica Schist at the top and BHQ at the bottom. Juxtaposed to the Rajhara- main block on the n-e is Kokan-East block, which is geologically exactly similar to the Kokan-West block. Another adjoining deposit falling in the leasehold of Rajhara Pahar known as Rajhara hill comprising Kondekasa blocks (Dalli mechanised mines), Jharandalli and Kokan-East respectively) lies to the west of Rajhara deposit, separated by a fault with a shift of about 1 km, the fault zone forming a valley. Further down west, juxtaposed to the Kondekasa block is the Mayurpani block operated by Dalli Manual mine.The area including the surroundings is drained by 2 nallahs. The more prominent Jharan nallah flows due east on the general ground on the northern side of Dalli hills and traverses the fault zone valley between Rajhara and Dalli hills turning due south at the northern edge of the fault valley and has finally been impounded to form the Rajhara dam reservoir. The other nallah, called Rajhara baba nallah, flows westwards on the general ground on the north of Rajhara hill along the side of the township and then meanders northwards through Rajhara and Chiklakasa towns. These are the 2 perennial watercourses, albeit small, in the area. Drainage of the Rajhara hills is affected by the various watershed lines in a dendritic pattern formed by the contours of the hill slopes, having any flow only during rains.
2.3 Geology of the Area
The Iron-Ore deposits of Dalli-Rajhara range are associated with the BIF (Banded Iron Formations) belonging to the Iron Ore Series of Dharwarian system of the pre-Cambrian or Archaic age (popularly known as the Iron-Ore Series of the Dharwarian system).They form a wide crescent shaped structure with the open limits pointing towards south and the apex covered by the younger argillaceous and calcareous meta-sediments of the pre-Cambrian age, forming the Chhattisgarh basin. In the east, the iron-ore series is known as the Singhbhum / Bonai series, whereas in the western part, it is locally known as Dalli-Rajhara and Bailadila series.

Basis for estimation: The estimation of mineral resource is done by using mine planning software (CAE Datamine Studio 3).The whole process of estimation of mineral resource and reserve has been done in two steps as follows. • 3D geological Ore body Modelling • Grade Estimation 3D geological Ore body Modelling: The process of creating a 3D geological ore body model typically makes use of the following: • Drill holes: Drill hole data are often used as a basis for creating geological models. In order to use these drill hole data for modelling purposes, all drill hole data was converted into 3D drill holes by using the following steps: • Section Strings Model*: It is the process of generating cross section profile of mineral zone by using the following steps: • Wire-frame Model*: The process is used for generation of 3D surface of iron ore body, topography and present surface profile of pit and form the basis determination of volume of various bodies like • Block Model**: *3D ore bodies can also be modelled using top and bottom contact contour strings (and subsequent wire-frame surfaces). **The optimized waste+ore block model is then typically passed on to the next step which I s Grade Estimation. Grade estimation: Grades are estimated into the cells of a geological block model in order to generate a resource block model. The input for grade estimation uses the results from a geo-statistical analysis in order to define mineralization zones and various grade estimation parameters.

Grade Estimation Processes: Grades are estimated for individual block model cells. The results of the geo-statistical analysis are used to prepare the geological sample and block model data before it is used in the grade estimation process. This preparation includes the mineralization code ,sample data,block model data, point data, drill hole data, compositing drill hole and regularizing block model data to produce models with fixed x, y and z cell sizes.
Grade Estimation Methods: There are a number of grade estimation methods available within Studio 3 like Nearest neighbour, Inverse Power Distance, Ordinary Kriging, Simple Kriging, Indicator Estimation, Sichel's T. The Inverse power distance method is used for grade estimation in this case.
Grade Estimation Inputs: The inputs to the above process include a sample file, block model, search volume parameters and others. Parameters are stored in parameter files or as parameters within each process. These are summarized below: • Samples: The composite drill hole data in mineralization zone are used as sample grades • Block Model: A prototype block model is required to interpolate the sample grades into for grade estimation methods. The specified prototype model contains cells and sub- cells, e.g. a geological block model, then grade values will be interpolated into the existing cells if there are sufficient samples within the search volume. • Search Volume: A search volume ellipsoid defines the spatial limits and associated parameters used for selecting which samples are to be used when estimating grades into a block model cell; this search volume and its parameters will be the same for each cell in a particular zone and is centered on the cell being estimated. More than one search volume may be defined e.g. for zonal control or for different grade fields. • Estimation Parameters: It is necessary to provide a set of estimation parameters for each grade to be estimated. The parameters should include items such as the estimation method, the search volume reference number etc.

Grade Estimation Outputs: The output from the block model grade estimation methods is a grade block model, which contains values for each estimated grade field. Additional output fields may include estimation variance, number of samples and search volume information. These additional fields are used for the determination of confidence limits for the grade estimates or for controlling detailed evaluations. A detailed or summary evaluation is performed on these grade block models to generate tonnage-grade reports. Method of Geological Modeling and Grade Estimation: Based on the method explained above, geological cross sections were developed with the help of boreholes. Strings are drawn bound borehole samples above threshold value of Fe for generating cross section of ore body and waste in pre-defined sections. After completion of strings along sections, cross-sections are linked to make a wire frame, which shows the surface of ore and waste with continuity. All ore strings are considered for ore body modelling of the Mine. In the same manner waste strings are linked and a waste wire-frame for intercalated of the mine is made.The sub-surface characters were compiled along with the borehole alignment after giving adequate consideration to the regional structures, the limits of the ore body and ore types were delineated. Suitable interpretations were made where the interconnecting features were not supported by the data. A prototype block model is defined in predefined grid with parent cell size of maximum dimension restricted to bench height (i.e. 10m in DMM and 5 m for JMM). This prototype block model is used for creating ore body and waste body separately by providing different zone code After making both the block; they are combined in a complete 3 Dimension block model of mine is made. Geo-statistical analysis is done for Fe, SiO2, Al2O3 to optimize the distribution of cell size ellipse. In the block model of the mine, quality of ore i.e. Fe%, SiO2% & Al2O3% are interpolated to view the quality at different levels and sections. The software interpolates quality ranges automatically by taking area of influence and cell sizes.

Air Quality
Mechanized opencast mining activities include drilling, blasting, shoveling, dumping, dozing and unloading, handling etc. are the root cause of generations of dust and suspended particles (SPM) in air, SOx and Nox are not major pollutants in such opencast iron ore mine.
Air Quality Management: Corrective measures adopted to control the air pollution are as under:- • .Water sprinkling along Haul roads. • .Atomized water spraying systems are being used at bunkers and conveyers transfer points. • Regular checking of gaseous emissions from HEME and light equipment. • Plantation of trees around fines dumps to prevent the micro particles becoming air borne. • .Afforestation of old and inactive dumps. • .Plantation and afforestation in all the vacant areas available in the lease hold area and acquired area. • Maintaining gardens in every shop Water Quality
At Rajhara, the ground water occurs below 433 mRL arising from the presence of aquifer. The company has constructed 2 nos of dams namely Boirdih and Rajhara Dam site for supply of drinking water and industrial water supply. The corrective measures have been taken to meet water quality confirming to the permissible limit. • No slime/slurry is generated since the plant processing is through dry circuit • The returned cooling water and other industrial used water are returned through open channel (nallas) in to Rajhara Dam site and other water of Rajhara dam site is not being used for any purpose other than cooling and industrial use • The quarry sump water is being pumped out to sump and taken to industrial dam site Rajhara

Therefore, the direct impact on environment outside the mines are negligible. As the mining operation activities have gone deeper, the impact will be gradually lowered down. BSP mine management have been provided either ear plug/muffs to the operators who are working throughout the shift hours. Vibrations level (due to blasting): Blasting is necessary for the recovery of ore. However, blasting can cause noise and vibration which can have impact upon neighboring premises. Proper control of blasting practices is therefore necessary to ensure both the safety of employee and protection of the community from adverse effect. Blasting usually results in both ground and airborn vibration. Latter commonly includes audible noise and vibration known as airblast, which can cause objects rattle and make noise. However generation and transmission of ground vibration can be controlled by design and methodology of blasting. All blasts both in Dalli mechanized mine & Jharandalli mine are being carried out by using Shock tube delay detonators. The charge/metre of shock tube is far 10 mg/ metre much lower than ordinary detonating fuse (6-10 g/metre) which helps in reduction of ground vibration and air over blast. This facilitates bottom initiation (down the hole) & reduction in maximum charge per delay by distributing the column charge along the number of deck generally two. The distances of the township and habitations from the mine areas and systematically designed blasts using state of the art initiation technology, blast generated ground vibrations and the air over pressure do not at all have any impact on the environment. Socio -Economic:-
In terms of the major socio-economic impacts, the mining activity provided more direct and indirect job opportunities and better economic standards to the people and others, through improved infrastructural, community facilities etc. Development of residential colony, creation of civic and welfare amenities like primary health care, communications, educational institutes, recreational facilities, etc, that already developed along with the mining activity and ensure better quality of life for the local population in future also. With ongoing of mining activities additional facilities for local population by way of better communication, postal services, educational facilities, advanced medical services etc. are on in the area. There is a marked change in social status of the area with commencement of mining activity by Bhilai Steel Plant. State Government is benefited through financial revenues in crores of rupees by way of royalty, sales tax etc. from the -direct and indirect operations in the project area. Central exchequer is also getting financial revenues by way of Income tax, Central Sales Tax etc.

However, small pockets are encountered occasionally, that quantity is being used for plantation. Surface subsidence mitigation through backfilling of mine void or by any other means and its monitoring mechanism. The primary reason for on-going monitoring of the mine site is to ensure that remediation measures, including earthworks, water treatment and drainage systems, proposed plantations, green belt, etc. function as intended. In addition, site surveillance may be necessary to demonstrate that the mine site remains safe and poses no environmental or health risks. Regular monitoring also allows for a proactive response where the rehabilitation process is found to be lacking in the desired results. For example, the proper discharge of rain water during monsoon will be ensure that there will be no pollutant discharge into the surrounding environment by making check dam and garland drains, discharge of rain water in scattered manner. Regular monitoring of active dumps, cracks, by proper monitoring and survey technique. Monitoring also provides valuable reference data for authorities in subsequent decision-making and in refining.

CHAPTER - III DESCRIPTION OF ENVIRONMENT
The present environmental status of the proposed projects has been studied covering 10 Km radius and presented in this chapter. It is necessary to know the present quality of the environment with respect to the various aspects considered under impact identification. These factors include air, water, noise, soil, meteorology, land use, flora & fauna, socio-economic and demographic pattern. For this purpose, a monitoring schedule was planned and data were collected during Pre Monsoon season (March- May 2015).
The baseline data on flora & fauna, socio-economic and demographic factors, land use pattern, forests, geology, hydro-geology, soil and agriculture, mineral resources etc. was carried out by field survey and secondary data has been collected from the State Government authorities and compilation of all season are presented in this chapter.
3.1 Air Environment
Identification of different pollutants, which are expected to be released into the atmosphere and having significant impact on the neighborhood, is an essential component in impact assessment of the air environment. The ambient air quality status of the study area of 10 km radial distance from the existing project will form the baseline information. The predicted impacts due to the project will be superimposed to find out the net (final) impacts (post-project scenario) on environment.
If the final impacts due to the proposed project are known at the planning stage of the project, a viable Environmental Management Plan (EMP) can be proposed to mitigate and minimize adverse effects on the environment. The design of the ambient air quality-monitoring network in the air quality surveillance programme is based on the following considerations.

3.1.1 CLIMATE AND METEOROLOGY
Regional climate and meteorology:
The study area lies in sub-tropical region where climate is characterized by hot summer, moderate monsoon and mild winter seasons. Summer is typically from March to mid June, when temperature ranges from a maximum of 45°C during daytime to a minimum of 27°C at night. Winter from December to February, when the maximum temperature during day time goes upto 36°C and minimum temperature 7°C at night. The area receives max annual rainfall of 1100mm. The rains predominantly occur between july to september due to south-west monsoon. The pattern of rainfall is highly irregular and varies significantly from year to year.
Wind speed and wind direction have a significant role on the dispersion of atmospheric pollutants and therefore the air quality of area. Ground level concentrations for the pollutants are inversely proportional to the wind speed in down wind direction while in upwind direction no effect will be observed and in cross wind directions partial effect due to the emission source is observed.
Micrometeorology at site Prevailing micro-meteorological conditions at site regulate the dispersion (and hence dilution) of air pollutants in the atmosphere. Therefore, study of meteorological conditions is an integral part of environmental impact assessment studies. Accordingly, a meteorological station was set up at project site. The following parameters were recorded at hourly intervals during pre monsoon seasons

Core-zone: PM10 and PM2.5 values were ranging between 48 and 83 µg/m3 and 20 3 and 38 µg/m respectively. The SO2 and NOx values were ranging between 14.8 and 22.6 µg/m3 and 21.2 and 28.3 µg/m3 respectively.
Bufferzone (March – May 2015) : PM10 and PM2.5 values were ranging between 37 and 86 µg/m3 and 16 and 39 µg/m3 respectively. The SO2 and NOx values were ranging between 8.2 and 22.7 µg/m3 and 10.3 and 28.3 µg/m3 respectively.
All CO values except in three locations in (corezone & crushing plant) were found to be below the detectable limit of <114.5 µg/m3. The maximum CO value observed was found to be <572.5 µg/m3. All heavy metal, Benzene and BAP values were
found to be Below Detectable Limit. There is a traceable amount of NH3 and O3, which is negligible while comparing with the prescribed AAQ standards. Based on the above discussions, it may be concluded that air quality data was found to be well within the prescribed limit.

3.3 Water Environment
Methodology Reconnaissance survey was carried out based on the location of ground and surface water bodies, which represent baseline condition. A total of 14 water samples Viz., 9 ground/drinking water samples (W1 – W9) and 5 surface water samples (W10–W14) were collected and analyzed as per standard methods.. Water samples were collected during the study period for Physico-chemical and Bacteriological parameters after taking suitable precautions and analysed as per Standard methods. Samples were collected for Chemical analysis as per procedure outlined in IS: 2488. Sterilized bottles were used for collection of water samples for bacteriological analysis, stored in icebox and transported to the laboratory for the analysis. Parameters like pH, Temperature, DO etc. were measured in the field while collecting the samples. MPN index of coliforms were determined in the laboratory as per Standard methods. The water quality monitoring stations are shown in Fig. III.4 and Table 3.9. The ground / surface water quality status is given in Table 3.10-3.11

Hydrogeology The formations within study Dalli-Rajhara range are associated with the banded ferruginous formations belonging to the Chilpi formations of Pre-Cambrian age, generally known as the iron ore series of the Dharwarian System. (Dharwarian system forms a wide crescent shaped structure extending from eastern India to central India. In the eastern part, the iron ore series is locally known as Singhbhumand Bonai iron ore series and Gangpur series; whereas in the Western part, it is locally known as the Dalli-Rajhara iron ore series and Bailadilla series.) The lithological assemblages of Pandradalli and Rajhara areas are dominantly of the hard metamorphic formations. The rock types consist of quartz and micaschist; gneisses and phyllite associated with banded hematite quartzite (BHQ). It may be noted that the overlying rock of the ore body at Rajhara is Phyllite (locally and in general). Though regionally highly deformed basic rock (KusumVolcanics) overlying the ferruginous formation have been reported by GSI. At some places of Rajhara mine, particularly on the HW side highly deformed and weathered gneisses are found. Thus, locally phyllite in the top and BHQ at the bottom exists in the study area.The water table with a gentle gradient (0.013) sloping towards Southwest was observed in the area. Hydrological Condition Hydrological condition of any area is influenced by number of natural and manmade factors. Geology is one important natural factor, which has been already described above. Besides this, geomorphology, drainage, topography, irrigation potential and soil plus land use are some other factors closely linked to the hydrological conditions. In Dalli-Rajhara area, the iron ore bodies lies in hilly topography mostly and ridges in the general plain. The general elevation of the ground is 425m above mean sea level. The drainage is dendritic and the drainage flow is along NE direction. Because of hard rock terrain surface run off is higher. On a regional scale the water level declining trend is observed. Study region encompasses some areas, which show long-term declining trends in water level. This is basically due to more draft compared to recharge. Decadal change in water levels is also indicative of these facts. As said earlier, at RMM the seepage from surface water to aquifer is less compared to those of sedimentary and porous formations though overall recharge in the study area is satisfactory. Ground Water Levels
The Hydrogeology study reveals that the pre-monsoon water levels vary from 2.46 m to 9.95 m with an average of 7.35 m and the post-monsoon water levels vary from 0.85 m to 8.86 m with an average of 4.68 m. The average water fluctuation in the area was found to be 2.67 m. As per, CGWA norms, the trends reveal that the groundwater exploitation in the study area is well within the acceptable limits.

Ground water configuration
To assess the water table configuration, a monitoring network consisting 24 bore / open wells, covering most of the villages falling within the core and buffer zones, was established in the study area. The wells are mostly used for domestic water needs. The water levels in these wells were monitored in post-monsoon period. This data is compared with the ground water levels of summer season data collected and the difference is tabulated. The details of the monitoring wells and water levels are given in the Table 3.12.

Pre-field interpretation of Satellite details
The false colour Composite (FCC) of IRS-1B Satellite data at 1:50000 scale has been used for pre-field interpretation work. Taking the help of topo sheets, geology, geo- morphology and by using the image elements the features were identified and delineated the boundaries roughly. Each feature is identified on image by their image elements like tone, texture, colour, shape, size, pattern and association. A tentative legend in terms and erosion was formulated. The sample areas for field check were selected covering all the physio-graphic land-use / land cover features cum image characteristics.
Ground Truth Collection
Ground truth field verification was conducted using both topo sheets and imagery. Representative sample areas were traversed to observe the broad land–use features and the sample areas were adjusted according to the field conditions. Detailed field observations and investigations were carried out and land–use features on the imagery were recorded.
Post field work
The base maps of the study area were prepared with the help of Survey of India Topo sheet at 1:50000 scale. Preliminary interpreted land use and the land cover features boundaries from IRS-1B FCC were modified in light of field information and the final thematic details were transferred on to the base maps. The tentative legend during the pre-field work were finalized. The final interpreted and classified thematic map was prepared using standard colour coding and detailed description of features with Standard symbols. All the classes are noted and marked by the standard legend on the map. Visual interpretation of multi-sensor false colour imagery composite of the area was prepared using LANDSAT satellite data. The land use /Land cover map is shown in Fig. III.5

3.5 Biological Environment
Introduction Studies on ecology and biodiversity are one of the important aspects of Environmental Impact Assessment with a view to conserve environmental quality and biodiversity. Ecological systems show complex inter-relationships between biotic and abiotic components including dependence, competition and mutualism. Protecting the environment and making efficient use of natural resources are two of the most pressing demands in the present stage of social development. Study of the biological environment is one of the most important aspects of Environmental Impact Assessment. This again has a special importance in case of mining project due its location. Mining leases and surrounding area are mostly located in the forest area. It is important to conserve natural flora and fauna of an area. EIA helps to identify the impact of the mining on the ecosystem and to check the damage. It suggests measures so that a particular ecosystem can improve & minimize damage. In the preset study, mainly terrestrial ecosystem has been considered. Every anthropogenic activity has some adverse impact on the environment. More often it is harmful to the environment than benign. However, mankind as it is developed today cannot live without taking up these activities for his food, security and other needs. Consequently, there is a need to harmonize developmental activities with the environmental concerns. Environmental impact assessment (EIA) is one of the tools available with the planners to achieve the above-mentioned goal.
Survey was under taken in the core zone and Buffer Zone during the monitoring period. The study was under taken during 21st to 23rd June 2015. Scope: The objectives of this study were as follows: To conduct brief study in cultivated and naturally occurring species in the core and buffer zone Assessment of species protected by specific legislation (Rare, endangered, critically endangered, endemic and vulnerable). To identify locations and features of ecological significance

The purpose of the desk study was to see land use of the study area through remote sensing images and species of local conservation value which may not have been present or apparent during the survey visit (e.g. spring/monsoon plants). Flora The structure and composition of vegetation and forest cover were studied by using phyto-sociological methods of vegetation survey, to analyze and estimate biodiversity, density, dominance and frequency of different members of plant

EIA & EMP for the Pandridalli and Rajhara Pahar Lease (220.42 Ha) of Bhilai Steel Plant, M/s SAIL for Capacity 3.5 MTPA ROM at Iron Ore Complex (IOC) Dalli-Rajhara, Tehsil: Dondi Distt Balod, Chhattisgarh-State. populations. Observations were made in the forest area (as possible) as well as in non-forest area by laying plots and adopting quadrate method. Quadrate method has been used to carry out the study of trees, shrubs, herbs and grasses. 20 m X 20 m for tree species, 5 m X 5 m quadrates for shrubs and 1 m X 1 m quadrates for herbs. List of floral species observed at each quadrant is documented and photographed. Species are compared with standard floras and identifying the plants need for conservation. The quadrate method includes laying down square sample plots or units for quantitative analysis of vegetation. It is actually the sample plot method given by Clements (1898); Philips (1959); Muller and Ellenberg (1974) and Rau and Wooten (1988).
Coexistence and competition both are affected directly by the number of individuals in the community. Therefore, it is essential to know the quantitative structure of the community. To characterize the community as a whole, certain parameters are used. The count of individuals of each species and total count of individuals of all species per plot, basal area are the major parameters. The derived parameters i.e. frequency, density, abundance, Importance Value Index (IVI), Simpson's Diversity Index give a clear picture of community structure in quantitative terms. The value of a parameter as estimated from the representative samples is the estimate, which is close to the real value
The formulae incorporating different parameters, analyzed and assessed for obtaining the baseline status of terrestrial biodiversity, are presented in Table . To characterize the vegetation in the study area, the data was collected and analyzed for describing the properties of vegetation with reference to species composition and functional attributes. Importance Value Index is the average of Relative Density, Relative Dominance, and Relative Frequency. Therefore, Importance Value Index is a reasonable measure to assess the overall significance of a species.
