In the study area about 70.86 % of the total population is literates. As per census 2011, about 28.16 % of the total are main workers, 0.080 % are marginal workers & 44.63 % of the total population are non – workers.
1.10 Anticipated Environmental Impact and Mitigation Measure
1.10.1 Topography
Topography of the surrounding area will remain unchanged while that of the mining lease area will change due to mining, excavation, dumping etc.
1.10.2 Drainage
No impact on drainage pattern within or outside the lease area due to mining project.
1.10.3 Impact on Air Environment
The modeling results show that all the pollutants will remain well within the limits of National Ambient Air Quality Standards after the commencement of mining.
1.10.4 Impact on Noise Environment
The expected noise levels in the working environment are compared with standards prescribed by occupational safety and health administration (OSHA- USA) & CPCB-NEW DELHI, the noise levels are expected to be in the acceptable range.

No surface water will be affected due to mining activity.
8 SH. SUNIL KUMAR KALWANI DRAFT EIA REPORT EIA/EMP REPORT FOR MANGANESE ORE MINING AT ARJUNI VILLAGE, TEHSIL KATANGI, BALAGHAT DISTRICT OF MADHYA PRADESH EXECUTIVE SUMMARY
Impact on Surface Water Quality
The opencast mining operation may cause water pollution. The sources of pollution generally are:
Wash off from dumps Pumping of mine water into surface water bodies Soil Erosion
Mitigation Measures
Lessee will construct garland drain to prevent the surface runoff from mine polluting the nearby surface water body. Water filled in the pit during rainy season will be used for dust suppression and green belt development.
Impact on Groundwater Quantity
Groundwater will be used for mining activities, only 6.5 KLD water will be used during mining operation.
Impact on Groundwater Quality
Ground Water will remain unaffected due to above mining activities, as mineral or soil does not contain any harmful ingredients that could leach down to the water table and also mining activity will not intersect the ground water table. Thus, the mine workings shall not affect the ground water quality.
Mitigation Measures of Groundwater
Mining will be carried out as per the approved mining plan, mining will not intersect groundwater table as mining will be carried out above the water table.
1.10.6 Impact on Flora and Fauna
As the mining activities will be confined to core zone only, no adverse impact is foreseen on the flora & fauna in the core zone. To prevent the entry of wildlife animals from entering the lease area proper fencing will be done all around the lease area.
1.10.7 Impact on Top Soil
The soil is present in a patch of very thin layer of 0.1 m. The soil removed from the mining area has been utilized for plantation in surrounding area. Since, soil removal is a regular activity; the excess soil is stacked separately for future use. Therefore, impact on soil in the lease area will be negligible.
9 SH. SUNIL KUMAR KALWANI DRAFT EIA REPORT EIA/EMP REPORT FOR MANGANESE ORE MINING AT ARJUNI VILLAGE, TEHSIL KATANGI, BALAGHAT DISTRICT OF MADHYA PRADESH EXECUTIVE SUMMARY
Mitigation Measures for Top Soil
Top soil will be stacked properly and used for back filling and after backfilling the part of lease area will be used for plantation.
1.10.8 Impact on Socio Economic Status
There is no inhabitation within the lease area. The only employment is based on agriculture, which is seasonal. The mining operations are providing employment to 14 local persons. So, due to the above mining project there will be social upliftment in the area.
1.11 Environment Monitoring Program
The monitoring of pollutant in mine will be carried out for air, water, soil and noise. It takes care of all monitoring needs of the mine. Additionally ambient air and work zone monitoring in mine will be conducted in every season near mining operation, loading and transportation (haul road) areas by Government approved private agency. The analysis results of air monitoring will be properly recorded and submitted to the statutory authorities from time to time. Noise measurement of mine equipment will be done once in a year, ambient air monitoring will be done once in one season at three locations (1 in upwind, 1in downwind, 1 in lease area. Ambient noise monitoring will be carried out at 3 locations, 1 within the lease area, and 2 locations of nearest habitation to the lease. Water quality monitoring will be done once in season at two locations & soil quality monitoring will be done once in a year at 2 locations within the study area.
1.12 Additional Studies
1.12.1 Risk Assessment and Disaster Management Plan
The following natural /industrial problems may be encountered during the mining operation are
Inundation-filling of the mine pit due to excessive rains. Slope failures at the mine faces or stacks. Accident due to fire.
Water table will not be encountered during proposed working. No high risk accidents like landslides, subsidence flood etc. have been apprehended. But possibility of accidental disaster is also not ruled out. Therefore, all the statutory precautions will be taken for quick evacuation as per the Mines Act 1952, the Mines Rules 1955, Rule of MMR- 1961 and the Rules of MCDR-1988.

1.13 Environment Management Plan
The environment management plan is prepared with a view to facilitate effective environmental management of the project. Apart from having an Environmental Management Plan, environment management cell consisting of mines manager, safety officer and environmental officer is constituted. A total of INR 2,51,750/- would be spent on environment management activities every year.
1.14 Project Benefits
The surrounding inhabitants around the mine lease area are mainly agricultural oriented. Opportunities for jobs activities will be created and mining will serve as a source of permanent livelihood. The mine will create employment directly or indirectly. Additional, certain works like transportation will be outsourced on contract. So, overall effect of mining is expected to be positive.
