10 Page10 SOCIO-ECONOMIC CONDITION OF THE AREA Based on the sample survey of the study area comprising of 10 km radius, the general socio-economic conditions of the local people can be summarized as below. There are 35 villages within the study area comprising of 6935 house hold. Majority of the population are industrial workers dependant on the local mines. S.T. population of %, which dominates the local population. Level of literacy is very low, which corresponds to their level of poverty. Employment in agricultural sector is seasonal and people look forward for miscellaneous jobs for their survival in the lean months. Mining could provide an important employment opportunity to the workers. Majority of the workers is addicted to country liquor that degenerate their working abilities. All the villages have dug wells and Hand pumps for drinking water. All most all villages are provided with electricity, 9 villages have bus stand which are 5 to 10 km away from rest of the villages. All of the villages are connected with kuchha and pucca roads. ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES The dust generated from mining activities is the primary source of air pollution. The emission sources include excavation and mining of ore bodies, drilling, blasting, screening/sizing and transportation within the project area. During air quality monitoring it is observed that dust generation is of short term and settle quickly within close ranges. There is very less scope of spreading of dust particles to the nearby residential areas as these operations are carried out at far off distances from the habitation areas. The impact of mining on the study area is assessed using ISCST Area & Line Source modeling and the resultant concentrations so derived are as below.

11 Page11 AQ6 Dadua AQ7 Chamakpur AQ8 Godindapur Mining activities and related operations can cause several beneficial and adverse imp0acts on the environment. The adverse impacts are proposed to mitigate. Using matrix method the impact on the environment has assessed. The expected beneficial impacts on the society are Health, Population/Migration, Employment, Literacy, Services and Aesthetic sense, The mining operation will generate direct employment for 349 no. of people. Communication, education, medical, power and employment facilities will be improved. Various mining operations will generate dust and gaseous pollutants. In a view to the scale of mining and existing environmental back ground condition it is anticipated that increment impact due to the mining operation will be within the prescribed limit. Further mitigation measures like water sprinkling and plantation will reduce the pollution level in the area. Contamination/siltation of surface water might occur due to mixing of runoff during rainy season with high-suspended particles, likely to be caused due to wash out of overburden. As it is proposed to construct settling tank and garland drain around the mining area the level of concentration of suspended particles in the surface water shall be well within the prescribed limit. The contamination of surface water may cause diseases in the area. Treatment of water will be done. Medical treatment will be provided as per the requirement. The impact on ground water will be marginal since proposed mining activities will be much above the ground water table. Due to the opencast mining project, the noise level of the area due to drilling, blasting transportation and running of heavy machineries will increase. Controlled blasting, proper maintenance of machineries and soundproof cabins, noise level can be minimized. The loss of vegetation due to mining activity and degradation of forest land will be compensated by the Compensatory Afforestation to be implemented as per the Forest Act. Further, due stabilization of dumps with rehabilitation will increase the area of plantation in order to bring an ecological balance.

There will be less chance of improvement in agriculture in the degraded land. However, there will be generation of employment and revenue for the local people from various ancillary mining activities including direct employment. ENVIRONMENT MONITORING PROGRAMME An environmental monitoring cell will be formed for regular environmental assessment on air, water, noise and soil qualities at nearby habitational area. Four permanent Air quality stations will be fixed as per the SPCB guidance to monitor the AAQ in quarterly basis. Quarterly water samples of ground water and surface water shall be collected and analysed. Noise level monitoring at Noise generating points and AAQ locations shall be done in quarterly basis. ADDITIONAL STUDIES Additional studies like soil erosion and nutrient quality at river bed soil will be taken up. PUBLIC HEARING As per the statutory provisions, the Public Hearing Meeting was held successfully on at 11:00 AM at Dadwan village of Keonjhar District, Odisha in respect of Environmental Assessment of Inganijharan Iron & Mn Mines of Sri. B.C Deb for production of 0.6 mtpa of Iron ore and MTPA Manganese ore over an area of ha.

13 Page13 PROJECT BENEFITS All the industries using iron and manganese as raw material will be benefited and add to the earning of revenue. The iron and manganese will be utilized in sponge iron, steel, smelter depending on their grade. Derived from the existing calculation, the net benefit at the end of the project at the present rate is Rs lakh. The ratio of Cost to benefit comes to be 1:1.33 or 1:1.3. Therefore the project is very much feasible. ENVIRONMENT MANAGEMENT PLAN The mining activities will have certain adverse effects on the existing environment like air, water land and noise. The following protection measures will be adopted to minimize pollution. Provision of planting emission, noise absorbing species (with dense/thick type canopy), soil erosion control and nutrient enhancing species To suppress fugitive dust, provision of water sprinkler, dust extractor etc at the dust generation source Adoption of control blasting techniques (suing advance non-electric detonator) Construction of garland drains around the quarry area and dumps with proper gradients The settling tank will have adequate dimension Drain and channel on Overburden dump in to sedimentation pond before discharging into natural drainage Proper maintenance of plant and machinery Providing sound proof cabins with proper ventilation Provision of personal protective equipments according to the pollution Dump yard stabilization through grading, compacting and suitable plantation Stone pitched walls in garland drains will be prepared to arrest flow of loose sediments Provision of speed breaker (stone pitching) at regular intervals in garland drains Silvipastoral plantation will be made to control erosion on dump slopes Phase wise reclamation through backfill shall be followed as per the Mine Plan No displacement is required for the proposed project. Hence R&R action plan is not applicable for the project.

14 Page14 PLANTATION PROGRAM Plantation over an area of 4.3hactareas have already been done with 8600 no of 2000 saplings per hectare. More plantations will be done gradually over the mined out area after backfilling. At the end of the mine life ha of area will be coved under plantation which is about 70% of the total area. Beside reclamation, plantation in the safety zone area shall be carried out under the plantation program as per the guidance and supervision of the State Forest Department.
