G uidelines covering the design and construction of new infrastructure, R&R packages, compensation. N eed for providing mitigation measures including guidelines for the reclamation of mined out areas, dumps and other disused areas.Proposed Environmental Safeguards/Mitigation Measures: Proposed Environmental Safeguards/Mitigation Measures Land Use/Landscape:- • To ensure land use changes happen in an optimal way so that impacts are minimised and land is reclaimed as soon as possible with predetermined land use patterns and landscape considerations. • To minimise the impacts on the local population with provision of environmental benefits to local people. • Top soil removal and conservation (bunds etc) • Overburden analysis and selective procedures for handling requirements including ripping & regradationPowerPoint Presentation: Socio-economic:- • Compensation to be paid for house and land acquired from each family. • House site 0.02 ha of developed plot to be given to each family. • Shifting allowance of Rs. 2000 to be paid per family. • Civic facilities to be provided in the rehabilitation colony will include water supply, power, roads and sanitation arrangements.PowerPoint Presentation: Water Quality • Overburden run-off collection and treatment with subsequent sediment control. • Oil & grease traps/separators. • Collection/storage of leachates , seepages, wash-offs with subsequent treatment. • Proper sanitation and provision of domestic and sewage effluents treatment. • Treatment of mine water discharges.PowerPoint Presentation: Air Quality:- • Dust suppression through heavy dust sprinklers/road watering trucks. • Dust extraction facilities with HEMM, crushing, screening and mineral handling plants. • Water sprays, hoods, dust collectors are to be used to control dusts from drilling. • Mineral handling plants are to be covered with proper enclosures. • Stabilisation through vegetation at various critical dust generating points/dump s.Noise and Vibrations:-: Noise and Vibrations :- Provision of ear plugs and ear muffs to reduce noise level exposure. Use of noise abatement paddings in fixed plant installations Use of silencers/mufflers in HEMM, noise insulating enclosures. Location of residential/resettlement colonies away from noise generating sourcesPowerPoint Presentation: Ecology:- • Providing environmental (wildlife) corridors to link adjacent habitat where mining is to be carried out in such sensitive afforested areas . • Suitable design of greenbelts/shelter beds with selected species should be provided which canalso respond to attenuate dust, gaseous emissions and noise levelsResidual Impacts: Residual Impacts ●Dust, ● Landscape ●Noise & vibrations, ●Risk &healthPublic Participation and Consultation: Public Participation and Consultation This is very vital for successful implementation of the project because this will help to: identify local knowledge/problems/needs. inform about the proposed development and allay fears and also to avoid complications. determine local response and integrate people into project. collect information which would otherwise be missed and use experts knowledge .Decision Making: Decision Making On the basis of the exercise, the Environmental Appraisal Committee on Mining Projects, make recommendations for approval or rejection of particular projects.Monitoring: Monitoring The purpose of the monitoring is : • T o ensure that no impacts are in excess of standards. • To check the predictions made in EIA. • To facilitate identification of any unidentified impacts and make provisions for their mitigation.
