2 ENVIRONMENTAL MANAGEMENT PLAN INTRODUCTION Mining, Environment and development have become complimentary to each other. EMP identifies the extent of the environmental, social and economic impacts of a project prior to mining of mineral and systematically examines both beneficial and adverse impacts of the proposed project over and above the prevailing conditions of environmental parameters and ensure that these impacts are taken into account during the project designing stage itself and the values of the combined impacts are never allowed to exceed and remain within the statutory norms. The EMP has been prepared with a view to ultimately ensure the adverse impacts are mininmized if these cannot be prevented altogether. Indeed, in a developing country like India, the supply of sand & gravel as a raw material for infrastructure development has a paramount importance. Therefore, the implementation of scientific mining principles through EMP plays a vital role in sustainable economic growth of our country. Benefits of Sustainable Sand Mining Prevents the river bed from becoming shallow due to the deposition of sediments. Scientific mining prevents the excessive erosion, which can damage flora, agriculture land and settlements situated in close proximity. It maintains the water retention capacity and help to avoid flood like situations. It generates useful economic resource for construction and generates employment in local areas. This project is meant for exploitation of ordinary sand from Boragam sand quarry as minor mineral over an area of Acres or Ha. The project site is located in Village- Boragam, Tahasil- Kodinga, District- Nabarangpur, Odisha. The revenue department, Govt. of Odisha has granted the lease in favour of Sri Padman Kumar Bisoi, S/o- Motising Bisoi, At/Po- Kerla, Tahasil- Kodinga, District- Nabarangpur, State- Odisha by Tahasildar, Kodinga, for 5 (five) years from to

7 Total 5.02 Ha/12.40 Acres The land use of the lease area will not change completely as the lease is non forest land. The excavated sand from lease area will be naturally reclaimed with the flow of water during rainy season, hence no change in land use. The mined out area will be replenished with sand deposit during monsoons.

8 CHAPTER ANTICIPATED ENVIRONMENT IMPACTS AND ITS MITIGATIVE MEASURES 2.1. Environmental Scenario: Any human activity in any environment produces impact, modifying it to a status which is considered adverse or beneficial according to the damage or improvement it brings about in physical, chemical and biological status of air, water, land including biota and in socio-cultural lifestyles and economy of the populace it affects. Depending on the nature of activities and existing status, the impacts are assessed for their importance. On the basis of the impact analysis, the mitigating action and future monitoring requirement are focused in the Environmental Management Plan for counting or minimizing adverse impacts so that abatement measures could be planned in advance for eco friendly mining in the area. The likely impacts on different environmental parameters due to mining project are discussed below. 2.2 Impacts on Land Environment and Mitigation Measures Land Environment The river mining does not involve any overburden/ waste. Thus, no waste dump sites are needed. Main aspects are excavation, loading and transportation activities. Deviation from planned mining procedure can lead to bank erosion /cutting and thereby river channel shifting degradation of land, causing loss of properties and degradation of surrounding landscape. The project area does not consist of any forest land. It does not consist of any human habitations. In the proposed Mining activity there will not be much impact on the land environment due to the following reasons. Excavation will be carried out in a manner so that water flow / course will not be obstructed. Safety zone or buffer area will be created from the river banks to minimize the instability & erosion and to increase the stability of structures. These safety zones will not be mined out. Sand mining will be restricted to a depth of 1.0 m. Therefore, the mining will not intersect the ground water table. Loss of habitat is minimized because the river bed mining will be carried only in dry bed which will not disturb the riverine ecosystem.

9 The mine working will remain confined to river bed only and in no case mining will disturb any surface area outside the river bed which may affect topography or drainage. The mining from river bed will not have impact on natural drainage of surrounding areas as the excavated sand from river bed is filled with first heavy flow in river during monsoon season. Change in Land Use Pattern The land use of the lease area will not change completely as the lease is non forest land. The excavated sand from lease area will be naturally reclaimed with the flow of water during rainy season, hence no change in land use. The mined out area will be replenished with sand deposit during monsoons. 2.3 Impact On Ambient Air Quality And Mitigation Measures Mitigative measures suggested for air emission control will be based on the baseline ambient air quality situation. From the point of view of maintenance of an acceptable ambient air quality in the lease area, it is desirable that the air quality needs to be monitored on a regular basis to check it vis-à-vis the NAAQS prescribed by MoEF&CC and in cases of non-compliance, appropriate mitigative measures will be adopted at the time of operation. In order to minimize impacts of mining on air and to maintain it within the prescribed limits of CPCB/ SPCB, an Environmental Management Plan (EMP) should be prepared. This will help in resolving all environmental and ecological issues likely to be caused due to mining in the area. During the course of sand mining no toxic substances are released into the atmosphere posing potential threat to health of human beings. In the mining activities, the source of gaseous emissions is engines of vehicles, loading operations. The reasons may be quality of fuel, improper operation of the engine, etc; proper maintenance of engines will improve combustion process and brings reduction in pollution. 2.4 Control of Dust Pollution The main pollutant in air is PM10, which is generated due to various mining activities. However to reduce the impact of dust pollution the following steps should be taken during various mining activities.

10 a) During Loading Operation (i) Water sprinkling will be done to reduce dust emission before & during loading operations. (ii) Avoid overloading of trucks and consequent spillage on the roads. b) During Transport Operation (i) All the haulage roads including the main ramp be kept wide, leveled, compacted and properly maintained and watered regularly during the shift operation to prevent generation of dust due to movement of trucks/ tippers, and other vehicles. (ii) Mineral carrying trucks should be effectively covered by Tarpaulin to avoid escape of fines to atmosphere. (iii) Regular Compaction and grading of haul roads to clear accumulation of loose material. (iv) Air quality should be regularly monitored both in the core zone and the buffer zone. c) Plantation Work Carried Out In order to reduce air pollution in the surroundings, green belt will be developed around mines, mine approach road. d) Monitoring Of Air Pollution Periodic air quality survey in the lease area will be carried out to monitor the changes consequent upon mining activities as per the norms of State Pollution Control Board. 2.5 Impact On Noise Environment And Mitigation Measures The ambient noise level monitoring carried out in and around the mine lease area to assess that ambient noise levels are well within the stipulated limits of MoEF&CC. Noise pollution due to transportation will not cause any problem to the inhabitants of this area as there is no human settlement in close proximity to the link roads in lease area. Effective steps should be taken to keep the noise level if any well below the DGMS prescribed limit of 85 dba.

11 Noise Abatement and Control (i) All the transport vehicles will be properly maintained to minimize generation of noise. (ii) Dense plantation in mining area will also reduce propagation of noise outside the core zone. (iii) Periodical monitoring of noise will be done to adopt corrective actions wherever needed. (iv) No other equipments except the transportation vehicles for loading will be allowed. (v) Plantation will be taken up along the approach roads. The plantation minimizes propagation of noise and also arrests dust. (vi) Noise level shall be maintained within prescribed limits in the working zone (for 8 hr. Exposure). (vii) Oiling & greasing at regular interval will be done. (viii) Minimum use of horns and speed limit of 10 km/hr. in the village area. (xi) Truck drivers will be issued ear plugs and ear muffs. It will be ensured that all transportation vehicles carry a valid PUC Certificates. Vibration Levels No vibrations of notable levels will be generated as blasting and drilling is not envisaged in the river bed sand mining project. 2.6 Impact On Water Environment And Its Mitigation Measures There will be no waste water generation from the mining operations during removal/ collection of mined material. Washrooms will be made available near working blocks. Waste water generated will be sanitary wastewater, which will be treated in septic tank and soak pits for the disposal of domestic/ washrooms effluents followed by sub surface dispersion. No diversion is proposed. There will not be any adverse impact on flow pattern, surface hydrology and ground water regime. Mining activities will be restricted to 3.0m depth, which will not cause much change in flow pattern of the river. There will be no change in surface water quality as river is seasonal. Ground water quality will not be affected due to mining activities

12 A safety zone around the lease area will be created and it will be left un-mined. The mining will not be allowed below the water table. Portable Bio-tiolets will be used; hence no sewage / liquid effluent will be generated and contamination is also not expected due to percolation. 2.7 Impacts of Soil Environment and Its Mitigation Measures The lease area is not having any top soil or fertile soil. The depth of mining shall be restricted to 3 m/water level, whichever is less. There is no environmental pollution due to the proposed quarrying as it is proposed to be a manual scooping of ordinary sand on the river bed. However the workers involved in quarrying and loading of sand will be provided with dust masks. Hence there will be no major occupational health hazards. River Bank Protection & Management Collection will be done during day light only. No stockpiling of collected Sand will be done. Mining will be conducted on demand. Mining will be done for 1.0 meter thickness at a time in the direction of river, to avoid the providing effect & maintaining the uniform surface. Markers showing water level will be marked on the site. 2.8 Green Belt Development The green belt in the lease area will be designed at the approach road, river bank and vicinity area to control dust, air & noise pollution, soil erosion and improve aesthetic environment. While considering the above aspects due care should be taken for selecting the suitable characteristic plant species such as fast growing, locally suitable plant species, resistant to specific pollutant and those which would maintain the ecological balance, soil and hydrological conditions. Scheme of Tree Plantation: Plantation is carried out around the mine, to reduce the dust emission at source. The total allotted lease area is Ha. Since the deposits are within the river, it has been planned to make plantation along the road connecting to the river & the river bank adjacent to the lease hold. Therefore, 20 plants are proposed per year with survival rate

13 of 80%. The dead plants will be replaced by fresh plantation to reclaim the original number. Year Saplings to be planted Species I 20 Peepal, Mango, Bel, II 20 Amaltas, Banyan, III 20 Neem, Bahada, Acacia IV 20 etc. and others as V 20 suggested by SPCB/ Total 100 Forest Department Place of Plantation Along the roads, in schools and public building, river bank adjacent to the lease hold and other social forestry program. 2.9 Impacts On Socio-Economic Environment And Mitigation Measures In general, socio- economic environment will have positive impact due to the mining project in the area. The deployed labourers will be from nearby villages only as these people are mainly dependent upon such mining activities. The proposed mining activity will generate direct employment and indirect employments for the people living in the surrounding area Impacts On Occupational Health And Safety Occupational health and safety are important to the people and domestic animals concerned. Periodic assessment of it will be useful. The villages and their inhabitants & domestic animals will not be disturbed from their settlements due to the mining operations. There is no inhabitation within the lease area. Therefore neither villages nor any part of village or any hamlet will be disturbed during the plan period of the mines. As the mining operations will not disturb or relocate any village or settlement, no adverse impact is anticipated on any human settlement. The mining operation does not disturb/relocate any human population or domestic animals.

14 Identifying workplace hazards, assessing risks to employee health and safety, are important. Health and safety points are important in many of the environmental aspects of the workplace. (i) Except dust generation there is no source which can show a probability for health related diseases and proper dust separation and dispersion. (ii) Dust masks be provided to the workers working in the dust prone areas as additional personal protective environment. (iii) The occupational health hazards if any will be reported. (iv) Awareness program be conducted about likely occupational health hazards so as to have preventive action in place. (v) Any workers health related problem be properly addressed. (vi) Periodical medical checkup be conducted. (vii) Promote occupational health and safety within workers in mine and develop safer and healthier ways of working. (viii) Help supervise the investigation of accidents and unsafe working conditions, study possible causes and recommend remedial action. (ix) Develop and implement training sessions for management, supervisors and workers on health and safety practices and legislation. (x) Coordinate emergency procedures, mine rescues, fire fighting and first aid crews Effect on Flora & Fauna. The direct impacts of the mining activity disturbances to land surfaces are usually significant, with the likelihood of destruction of biodiversity within natural ecosystems through removal of natural soils, plants and the floral dependent animals. No wildlife population is present in the study area except the common type of birds and domestic animals. As the mining is restricted to very small area there is no likelihood of any deforestation being caused. No significant long-term residual impacts on fauna due to mining activity of the proposed mine is expected Visual Impact After reclamation aesthetic value will enhance.

15 Summary As per above discussion there is no major impact on the environment due to mining except fugitive emission in the form of dust generated during handling and loading of mineral. The adequate preventive measures will be adopted to contain the various pollutants within permissible limits. Plantation development will be carried out in the mine premises, along the approach roads, around Govt. buildings, school approx 20 trees per year. It will prove an effective pollution mitigate technique and help avoid soil erosion during monsoon season. Employment opportunities will be provided to the locals as extraction of sand from the lease area is an important prevailing occupation for them for their livelihood.

16 3.0 Environment Monitoring Plan CHAPTER Introduction Regular monitoring of environmental parameters is of immense importance to assess the status of environment during project operation. The knowledge of baseline conditions comes through monitoring of environmental parameters; the monitoring program will serve as an indicator for environmental conditions due to operation of the project. Monitoring is an important tool for the management, environmentalist and policy maker to make changes in pollution control equipments, environmental policy to save environment. It is decision making tool for the state of environment carried out through periodic monitoring. Further, 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 program of the environmental parameters is essential to take into account the changes in the environmental quality over the period of time to comply environmental conditions necessary to save environment. 3.2 Implémentation of EMP & Environmental Monitoring Programme The EMP has been developed with a view to bring down the levels of impacts as discussed in the last chapter. A large part of the sampling and measurement activities will be concerned with long term monitoring aimed at providing an early warning of any desirable changes or trends in the natural environment that could be associated with mining and allied activities. This is essential to determine where the changes are a response to a cycle of climatic conditions or are due to the mining or allied activities. In particular, a monitoring strategy is required to ensure that all environmental resources, which may subjected to contamination, are kept under review. Monitoring of the individual elements of the environment is necessary. Monitoring of environmental parameters, compliances, supervision and reporting will be done through outsourcing basis. The routine monitoring program will be implemented as per CPCB & MoEF & CC guidelines. Environmental Monitoring Program will be conducted on outsource basis once in season except monsoon. The Environmental Monitoring of environmental parameters at site and data thus generated will be regularly furnished to the State regulatory agencies/ State Pollution Control Board at the frequency of six month.

17 Sl. No. Description Environmental Monitoring Programme Frequency of Monitoring 1. Ambient Air Quality in and around mines One Sample after 24 hours continuous monitoring will be collected twice a week in every year during mining period or as per norms of SPCB, Odisha 2. Water Quality Annually once for 2 surface water samples during mining period or as per norms of SPCB, Odisha & MoEF for various parameters 3.
