The source of water shall be mine water of Selected Dhori Quarry & from Integrated Water Supply System (IWSS) and no discharge is being done outside the project boundary. Water is also being recycled as much as practically possible and several measures are being undertaken for further augmentation of water resources in project command area. Present Mine Inflow (Monsoon Season): Since Selected Dhori GoM is an existing old mine of 2.25 MTPA rated capacity and working in combined Karo group of seams from VI to X and the expansion project of Selected Dhori GoM (Normative capacity: 8.25 MTPA and Peak capacity: 11.0 MTPA) proposes to exploit the same combined Karo group of seams from VI to X with the increase in production rate. All the seams and aquifers of the project has already been exposed and only rate of production has to increase with the same set of technology. Therefore mine inflow (non-monsoon) will remain the same for the future production target i.e. 1,305 m3/day. Thus the proposed mine inflow (Monsoon+Non-monsoon)= 8346 m3/day.
SN Description Seepage 1 Total Excavated Area 2115900 sqm 2 Monsoon rainfall 1.040 m 3 Run-off coefficient 0.60 4 Inflow of water to the quarry 7041 cum/day

Impact on Land Environment
The excess coal was produced from the same quarry area of the mine as mentioned in the approved EIA/EMP of 2.25 Mty. The excess coal production was mainly to prevent the propagation of fire. No land outside the project area has been broken. The most effective method to control the fire is to excavate the carbonaceous material and then it is proposed to control the fire through technical reclamation/fire blanketing and will be reclaimed as per the proposed Post-mining land use plan as given below.

Impact on Water Environment
Water can be categorized in two categories: a. Ground Water b. Surface Water
Ground Water Potential Damage on Ground water due to Excess Production are as given below:
1. Depletion of ground water level due to mine seepage and obstruction of
Rainwater infiltration due to mining Activities 2. Impact on ground water quality.
1. Depletion of Ground Water Level:
To evaluate the behaviour of long term groundwater level trends, long term water level data from the permanent observation well of CGWB have been referred. Long term water level trends at hydrograph station Turyo Basti (Well No.: EB-01) was collected and is given below. It was estimated that the radius of influence due to project activities on ground water regime is about 220m and the Village Turyo Basti falls within this zone of influence. Hence, the impact due to excess production on ground water regime can be well understood by studying the ground water pattern at Turyo village. Long term pre monsoon and post monsoon water level are shown in the table given below and the hydrograph of these stations are shown in Figure.

Noise and Vibration
The major source of noise and vibration due to mining and its allied activities are as listed below.
x Drilling and Blasting x Heavy Machinery x Movement of coal transportation vehicles.
Existing Control Measures x Controlled blasting is being practiced. x Blasting is being done at specific time and care is being taken that no person
is present in the vicinity during the time of blasting. x No blasting has been carried out within the 150 m of any structure nearby. x As per the blast monitoring report, it was observed that the vibration levels
are less than 5mm/sec. x Workmen who are susceptible to heavy noise exposure have been provided
with ear muffs and sound proof operator cabins. The noise levels monitored in the previous years by CMPDI are as given below.

From the above table, it can be observed that there is no significant damage due to mining activities on noise environment. The permission obtained for controlled blasting is enclosed with this report. As no permanent structure exists within 300 mtrs from the working faces of the mine, There is no significant damage from vibration.
Impact on Flora Fauna
The excess production was excavated from the same quarry without diversion of any additional land. Therefore, due to excess production no additional forest land has got affected. The total forest land involved in Selected Dhori GoM is 212.23 Ha which has already been Stage II diverted. As per the Flora Fauna study carried out QCI accredited consultant of CMPDI, the following observations are noted.
x Coal mining activity has been prevalent in this region prior to nationalization period, the flora & fauna especially in the core zone of the project is almost degraded.
x In buffer zone, the forest occurs in small sporadic patches consist of open mixed deciduous vegetation of Shorearobusta dominant tree species. The remaining area is either barren or used as farm land for cultivation by the villagers growing both traditional and commercial crop varieties.
x It was found that there was no endangered, threatened and endemic category fauna as per the IUCN-Red Data Book (RDB), Botanical Survey of India (BSI), Indian wildlife (Protection) Act, 1972. During survey no endangered and threatened aquatic fauna have been noticed by the investigation team.
Therefore, it can be observed that there is no direct impact on flora & fauna due to excess production because no additional forest land has been broken and the forest land involved has already been diverted and NPV and compensatory afforestation cost for double of the area has already been submitted to statutory bodies. The pattern of incremental fugitive dust concentrations in buffer has been studied in the previous section shows that there is a significant increase in dust levels at Turiyo village and Pichhri Village. This increase in GLC might have affected the plantation and its productivity
33
Impact on Socio Economic Profile
Mining activity in the study area is being taken up since long time. There has been a predominant influx of people observed in the recent decades due to income generation and availability of resources. Coal mining is a major source of employment for this area. There is no direct adverse impact that can be observed due to violation activity on the socio economic status of nearby villagers. In turn coal handling and despatch activities of excess production have created excess income to the villagers Preventive/Mitigative measures adopted
x CSR activities are carried out continuously. More emphasis of CSR are in drinking water, infrastructure, sanitation, education, skill development, social empowerment, water management, environment, sports and health.
x CSR expenditure detail is given below. It is not the complete detail but It is since organised CSR started in the area. CSR activities were being carried out prior the period given below.

CHAPTER- I 1.0 INTRODUCTION 1.1 Location Selected Dhori block is located in easternmost part of the East Bokaro Coal field. It is bounded by Tisri Nala in the west, river Damodar in the south, Tarmi Colliery in the east and village Gunjardih in the north. It covers an area of about 3 sq.km and falls within latitudes 230 45’N to 230 48'N and longitudes 860 02'E to 850 03'E and falls in the Survey of India Toposheet no. 73 I/1.
1.2 Communication Selected Dhori is well connected by rail and road. The Gomoh-Barkakana loop line of the Eastern Railway passes adjacent to the area. The nearest railway Station ‘Phusro' on the Barkakana-Gomoh loop line is about 2 Km to the West of the area. 1.3 Topography with drainage pattern of area The area presents all rugged topography being traversed by a major flat topped hill, some isolated hillocks and intervening plain lands and valley occupied by paddy fields, quarters and dumps of some existing and abandoned quarries. The hook-shaped plateau that covers a major part of the area runs in N-S direction and attains a maximum height of 329.79m. The river Damodar serves as a perennial source of water for the area. The Tisri Nala, a prominent tributary of Damodar, flows from north to south and forms the western boundary of the area.

1.4 Climate & Vegetation The area witnesses a sub-tropical climate. Heavy rainfall occurs in the months of June to September. The area is thickly forested. 1.5 Geology The basic geological information given in this report is based on the “Geological Report on Exploration carried out in Selected Dhori Block, East Bokaro Coalfield”, prepared by the Department of Geology, Projects and Construction Division, CCL, in May, 1977. Subsequently, plans showing floor and roof contours and isochores of the thick Karo group of seams (VI to X) were revised on the basis of additional drilling data and surface contours, by the Geology Department of CCL and RI-3, CMPDIL during October-November, 1978. Selected Dhori block falls in the easternmost part of the East Bokaro Coalfield. The Karo group of seams (VI to X) are available in this block. The Selected Dhori block forms a part of the northern limb of the East-West elongated synclinal sub-basin of the East Bokaro coalfield. The Barakar beds strike east-west and dip in southerly direction at angles varying in amount from 7o to 12o. The area has been traversed by 12 faults (three distinct set of faults) of varying magnitude and trend. Sequence of Coal Seams in Selected Dhori Block
